Title: Method for evaluating and predicting placenta-derived diseases and kit

Description:
TECHNICAL FIELD 
     The present disclosure relates to the field of biological detection. Specifically, the present disclosure relates to a method for predicting and evaluating the risk of pregnancy complications associated with placental dysplasia, and a kit. More specifically, the present disclosure relates to a method for evaluating and predicting, at early pregnancy (12 to 16 weeks of gestation), the risk of pregnant women being afflicted with gestational hypertension and other types of placenta-derived diseases in the perinatal period, and a kit. More specifically, the present disclosure relates to a method for evaluating and predicting the risk of preeclampsia, and a kit. 
     BACKGROUND 
     Formation of a placenta is a vital guarantee for normal mammalian pregnancy and healthy fetal growth. The placenta is a maternal-fetal interface and plays important roles in, e.g., providing necessary nutrition support for a fetus and regulating maternal immune tolerance. From the standpoint of embryonic development, the placenta originates from the extraembryonic ectoderm (ExE). Its formation course starts with implantation of the blastocyst, i.e., 6 to 7 days after fertilization, and its development course continues throughout the gestation. The blastocyst ready for implantation has differentiated into the inner cell mass (ICM) with the potential to develop into an embryo and the trophoectoderm (TE) with the potential to differentiate into a placental tissue. Placental growth and development involves such biological processes as degradation of extracellular matrix, trophoblastic invasion, cell differentiation of placental lineage, promotion of angiogenesis, cell migration, and regulation of tolerance of the maternal immune system. In addition, the placental development is also accompanied by dynamic epigenetic processes, such as a remodeling process of whole-genome methylation and regulation of expression levels by genomic imprinting, which plays important roles in determining the fate of the cell lineage and regulating the expression of placental development-associated genes and the embryonic development. 
     DNA methylation modification is to transfer a methyl group to the fifth carbon atom of cytosine under the action of methyltransferases to form 5-methylcytosine. Most of DNA methylation modifications occur at CpG loci, with very few occurring at CHG or CHH loci (H represents C, T, or A). DNA methylation modifications are roughly similar in cells from the same developmental lineage. When cells undergo differentiation, transdifferentiation, canceration, etc., the DNA methylation modifications will be altered. Under different physiological and pathological conditions, the DNA methylation modification to the same cell may also be altered. Therefore, the pattern of the DNA methylation modification may be used to deduce the origin of its tissue and to evaluate the pathological and physiological status of the tissue cell where it is found. 
     During the development of zygote, the DNA methylation modification is a highly dynamic process. In a few hours after zygote formation, an erasure of DNA methylation occurs progressively within a whole-genome range to thereby reduce the mean whole-genome methylation level from approximately 41% after fertilization to 9% at the 2-cell stage. The genome of blastocyst is almost completely hypo-methylated prior to implantation. The unerased methylation modification is known as methylation imprinting. After implantation of blastocyst, the de novo methylation of DNA will occur, which is closely related to the regulation of the expression of embryonic development-associated genes. During the de novo methylation, intra- and extra-embryonic tissues show different patterns, with 80% of methylated loci being differentially modified at the whole-genome level in the intra- and extra-embryonic tissues; for an individual methylated locus, the DNA methylation modification in the intra-embryonic tissue is in an “all-or-none” pattern, i.e., a state that a particular methylated locus is completely methylated or completely hypo-methylated, whereas a majority of CpG loci in the extra-embryonic tissues are hemi-methylated. 
     For the vast majority of genes on autosomes, alleles inherited from both paternal and maternal sources are expressed simultaneously. However, there are a few genes, in which either the paternal or maternal allele is expressed. Such monoallelic expression, i.e., a genomic imprinting phenomenon, is realized by asymmetric epigenetic modifications between different parents. The occurrence of imprinted gene is of significance to normal tissue differentiation and embryonic development. For example, fetal growth restriction (FGR) is associated with the loss of genomic imprinting on IGF2, which, in turn, leads to an undersized placenta or villous hypoplasia. The genomic imprinting can be realized by differential methylation modifications of the paternal and maternal genomes. The methylation modifications to imprinted genes are regulated by an imprinting control region (ICR). The ICR may remain methylated during the whole-genome erasure of methylations in the early development of a zygote, and the methylated ICR may affect surrounding genes such that they are methylation modified as well. Most of the ICRs in the oocyte are methylated, and they are mostly distributed in the CpG island (CGI) containing dense methylated loci. In the early stage of embryonic development, genes are transcribed with an alternative promoter. The alternative promoters are upstream of the classic promoter on the CGI, and are mostly retrotransposons with a long terminal repeat (LTR), also referred to as endoretroviruses (ERVs). ERVs make up approximately 8% of the human genome. Human-derived ERVs lose their retrotransposon activity but retain their function as alternative promoters. For example, the transcription of the CYP19A1 gene in the placenta is driven by a tissue-specific promoter—MER21 LTR, which belongs to the ERV family and enables placental cells to express tissue-specific transcripts through an alternative splicing mechanism. 
     Preeclampsia (PE) is a common pregnancy complication that may seriously threaten lives of mother and fetus in the perinatal period. In China, the morbidity of preeclampsia is approximately 2% to 6%, and preeclampsia is the second leading cause of maternal death. In clinic, preeclampsia is typically characterized by first onset of hypertension and proteinuria after 20 weeks of gestation, often accompanied by edema and hyperuricemia. Onset of preeclampsia will cause fatal damages to the liver function, kidney function, and coagulation function of pregnant women. Pregnant women with severe preeclampsia may develop microangiopathic hemolytic anemia, elevated lactate dehydrogenase and liver enzymes, headache, or other neurological symptoms. 
     It is now generally acceptable that preeclampsia is mainly caused by inadequate invasion of trophoblast into the uterine decidua and inadequate remodeling of distal uterine spiral arteries. However, there is still no clinical means of treating preeclampsia and the only cure is induction of labor. Several clinical trials have demonstrated that taking low-dose aspirin before 16 weeks of gestation may reduce the morbidity of preeclampsia. In order to relieve the pressure of clinical management in preeclampsia, strengthen the early prevention of preeclampsia, and reduce its morbidity, there is a need to strengthen early screening of preeclampsia. Previous scientific research has shown that Congo red dye could bind to the β-amyloid protein in urine of pregnant women with preeclampsia, and turns red. In the plasma of patients with preeclampsia, as the placental development-associated proteins, the PlGF level is decreased, while the sFlt1 level is increased. Therefore, the Congo red staining result and the PlGF/sFlt1 ratio may be used as indicators for clinical diagnosis and prediction of preeclampsia. However, the above biochemical assay is only applicable to people at 25 weeks of gestational age or more but not to people at less than 16 weeks of gestational age. Because aspirin intervention is only effective before 16 weeks of gestational age, the above method is relatively limited in guiding physicians on medication and preventing preeclampsia. Scientific findings have shown that there is a significant difference in DNA methylation modifications between the preeclamptic placenta and the placenta in normal pregnancy. 
     Cell-free DNA (cfDNA) is a single- or double-stranded DNA fragment present in human circulating blood, urine, and other body fluids. Most of cfDNAs are 200 bp or less in length, and they are present in plasma at very low concentrations (about 1 to about 100 ng/mL). cfDNA results mainly from apoptosis because its fragmentation pattern is very similar to DNA fragments generated by apoptosis. 90% or more of cfDNAs are derived from cells of the hematopoietic lineage. The cfDNAs in maternal plasma is a mixture of maternal and placental cfDNAs, of which fetal/placental cfDNAs are in a smaller proportion (proportion of placental cfDNAs: 3% to 15%). Existing methods for prenatal diagnosis have realized early screening for fetal genetic diseases, e.g., chromosomal polyploidization diseases such as Down&#39;s syndrome (T21), by deep sequencing of cfDNAs in maternal plasma. 
     In the prior art, a large number of clinical trials have been conducted to predict the risk of pregnancy complications associated with placental dysplasia by using, alone or in combination, a biochemical assay, a biophysical assay, and epidemiological statistics. However, subject to their sensitivity and specificity, these clinical trials also fail to achieve effective evaluation and prediction of the onset risks of the aforesaid diseases at an earlier gestational age. To date, there have been no proven and reliable screening methods used in clinical practice.

     DETAILED DESCRIPTION 
     Definitions 
     When used in combination with the term “including” in the claims and/or specification, the word “a” or “an” may refer to “one”, or refer to “one or more”, “at least one”, and “one or more than one”. 
     As used in the claims and specification, the term “including”, “having”, “comprising”, or “containing” is intended to be inclusive or open-ended, and does not exclude additional or unrecited elements or methods and steps. 
     Throughout the application document, the term “about” means that a value includes the error or standard deviation caused by the device or method used to measure the value. 
     It is applicable to the content disclosed herein that the term “or” is defined only as alternatives and “and/or”, but the term “or” used herein refers to “and/or” unless otherwise expressly stated to be only alternatives or mutual exclusion between alternatives. 
     In the present disclosure, unless otherwise specified, all of the positions of human chromosomes described herein are numbered as per the GRCh37 version. 
     In the present disclosure, “fetus” refers to an embryo after 8 weeks of gestational age. “Gestational age” is a measure of the age of gestation, starting from a woman&#39;s last menstrual period (LMP) or a corresponding age estimated by an additional method. In obstetrics, the gestational age refers to the embryonic or fetal age+two weeks. For human beings, it is common that labor occurs within 37 to 42 weeks of gestational age, but it usually occurs at about 40 weeks of gestational age. 
     In the present disclosure, “early pregnancy” refers to the gestational age at or before 16 weeks. 
     In the present disclosure, “normal pregnancy” refers to the pregnancy during which no significant pregnancy complications occur, the pregnancy complications including, but not limited to, gestational hypertension, gestational diabetes, twin-to-twin transfusion syndrome, fetal intrauterine growth restriction, HELLP syndrome, preeclampsia, severe preeclampsia, secondary preeclampsia, atypical preeclampsia, and eclampsia. 
     In the present disclosure, “control pregnancy” refers to the pregnancy without preeclampsia, severe preeclampsia, secondary preeclampsia, atypical preeclampsia, or eclampsia. To wit, the “control pregnancy” used herein may include “normal pregnancy”. 
     In the present disclosure, “placenta-derived gestational disorder” refers to a disorder developed during pregnancy due to a developmental defect or loss of function of the placental tissue. Exemplarily, the “placenta-derived gestational disorder” used herein is selected form gestational diabetes, twin-to-twin transfusion syndrome, fetal intrauterine growth restriction, gestational hypertension, eclampsia, preeclampsia, severe preeclampsia, secondary preeclampsia, atypical preeclampsia, or HELLP syndrome. 
     In the present disclosure, “gestational diabetes” means that a woman, who does not have diabetes before pregnancy, has symptoms of hyperglycemia during pregnancy. 
     In the present disclosure, “twin-to-twin transfusion syndrome” is the commonest complication occurring in monochorionic diamniotic twins. Because the monochorionic diamniotic twins share one placenta, in which the networks of a large number of blood vessels are anastomosed with one another, the blood of the two fetuses communicate directly, with one fetus being a donor twin with growth retardation, anemia, oliguria, oligohydramnios, or hypotension, while the other fetus being a recipient twin with plethora, polyuria, polyhydramnios, cardiomegaly, hypertension, or edema. The donor twin may die in the womb due to intrauterine growth distress, and the recipient twin may also die from heart failure. 
     In the present disclosure, “fetal growth restriction” means that the fetal weight is less than the tenth percentile or less than two standard deviations of the average weight for the same gestational age. 
     In the present disclosure, “gestational hypertension” refers to onset of diastolic blood pressure ≥90 mm Hg and (or) systolic blood pressure ≥140 mm Hg (measured at intervals between 6 hours and 1 week) after 20 weeks of gestational age without proteinuria, neurological symptoms, symptoms of liver or kidney damage, or symptoms of HELLP syndrome. 
     In the present disclosure, “preeclampsia” refers to new onset of systolic blood pressure ≥140 mm Hg and (or) diastolic blood pressure ≥90 mm Hg after 20 weeks of gestational age, proteinuria ≥300 mg/24 h, or qualitative test (+). In the present disclosure, preeclampsia may include severe preeclampsia, secondary preeclampsia, and atypical preeclampsia. 
     In the present disclosure, “severe preeclampsia” refers to onset of systolic blood pressure ≥160 mm Hg and (or) diastolic blood pressure ≥110 mm Hg after 20 weeks of gestational age, 24-hour proteinuria level of greater than or equal to 2.0 g and (or) qualitative test (++) or more, together with at least one of: serum creatinine ≥106 μmol/L or elevated than before, blood platelets &lt;100,000/mm 3 , or developing microangiopathic hemolytic anemia, elevated lactate dehydrogenase or liver enzymes, with headache or other neurological or visual symptoms, persistent epigastric discomfort, or pulmonary edema. 
     In the present disclosure, “secondary preeclampsia” refers to onset of systolic blood pressure ≥140 mm Hg and (or) diastolic blood pressure ≥90 mm Hg before pregnancy or before 20 weeks of gestational age, and onset of preeclampsia or eclampsia during pregnancy. 
     In the present disclosure, “atypical preeclampsia” refers to occurrence of symptoms of gestational hypertension with one of: neurological symptoms, hemolysis, elevated liver enzymes, and low counts of platelets, but without proteinuria (abbreviated from preeclampsia without symptoms of renal impairment), or with proteinuria (more than two rapid strip tests being positive) along with one of: neurological symptoms, hemolysis, elevated liver enzymes, low counts of platelets, but without hypertension (abbreviated from preeclampsia without symptoms of hypertension). 
     In the present disclosure, “HELLP syndrome” refers to a syndrome characterized by hemolysis, elevated liver enzymes, and low counts of platelets during pregnancy, which is a serious complication of gestational hypertension. 
     In the present disclosure, “transposon”, also known as a mobile gene or a jumping gene, is a DNA sequence that may be inserted and cleaved in a genome and can change its own location. 
     “Sequence identity” and “percent identity” used herein refer to the percentage of nucleotides that are the same (i.e., identical) between two or more polynucleotides. The sequence identity between two or more polynucleotides can be determined by aligning the nucleotide sequences of polynucleotides and scoring the number of positions at which nucleotides are identical in the aligned polynucleotides, and comparing the number of these positions with the number of positions at which nucleotides are different in the aligned polynucleotides. Polynucleotides may differ at one position by, e.g., containing a different nucleotide (i.e., substitution or mutation) or deleting a nucleotide (i.e., a nucleotide insertion or a nucleotide deletion in one or two polynucleotides). The sequence identity may be calculated by dividing the number of positions at which nucleotides are identical by the total number of polynucleotides. For example, the percent identity may be calculated by dividing the number of positions at which nucleotides are identical by the total number of nucleotides in the polynucleotides, and multiplying the result by 100. 
     In some inventions, the present disclosure relates to the stringency of hybridization conditions used to define the degree of complementarity between two polynucleotides. Optionally, the aforesaid polynucleotides may be selected from DNA. “Stringency” used herein refers to the temperature and ionic strength conditions during hybridization and the presence or absence of some organic solvents. The higher the stringency, the higher the degree of complementarity between the target nucleotide sequence and the labeled polynucleotide sequence. “Stringent conditions” refers to the temperature and ion conditions under which only nucleotide sequences with high-frequency complementary bases hybridize. The term “hybridization under high-stringency or very high-stringency conditions” used herein describes the conditions for hybridization and washing. Guidance for hybridization reactions is described in Current Protocols in Molecular Biology, John Wiley &amp; Sons, N.Y. (1989), 6.3.1-6.3.6. 
     In the present disclosure, “high-stringency hybridization conditions” means that following the standard DNA blotting procedures, a probe of at least 100 nucleotides in length pre-hybridizes or hybridizes for 12 to 24 hours at 42° C. in 5×SSPE (saline sodium phosphate EDTA), 0.3% SDS, 200 μg/ml of sheared and denatured salmon sperm DNA, and 50% formamide. Finally, the vector material is washed three times at 65° C. with 2×SSC and 0.2% SDS, each for 15 min. 
     In the present disclosure, “very high-stringency hybridization conditions” means that following the standard DNA blotting procedures, a probe of at least 100 nucleotides in length pre-hybridizes or hybridizes for 12 to 24 hours at 42° C. in 5×SSPE (saline sodium phosphate EDTA), 0.3% SDS, 200 μg/ml of sheared and denatured salmon sperm DNA, and 50% formamide. Finally, the vector material is washed three times at 70° C. with 2×SSC and 0.2% SDS, each for 15 min. 
     In the present disclosure, “whole-genome bisulfite sequencing” is also known as WGBS. The sequencing is based on the principle of treating a sample to be tested with bisulfite to convert the unmethylated C bases in the genome into U and then into T by PCR amplification, so that they are distinguished from the C bases originally with methylation modifications, and then aligned with the reference sequence by the high-throughput sequencing technology, thereby determining whether methylations occur at the CpG/CHG/CHH loci. This is particularly suitable for drawing whole-genome DNA methylation profiles at single-base resolution. 
     In the present disclosure, “cell-free DNA”, also known as cfDNA, is the partially degraded endogenous DNA that is free from extracellular parts in human circulating blood, urine, and other body fluids. cfDNAs are mostly 200 bp or less in length and present in plasma at very low concentrations (about 1 to about 100 ng/mL). 
     In the present disclosure, “genomic DNA”, also known as “gDNA”, refers to the total DNA content of an organism in the haploid state. 
     In the present disclosure, “locus” corresponds to a single locus, which may be a single base position or a group of related base positions, such as a CpG locus. 
     In the present disclosure, “DNA methylation” refers to a process of transferring a methyl group from S-adenosyl methionine (SAM) as a methyl donor to a specific base under the catalysis of DNA methyltransferases in an organism. In mammals, methylation mainly takes place at the 5′C-terminal of nucleotide cytosine residues. On human genomes, a large amount of DNA methylations take place on cytosines in CpG dinucleotides, where C is cytosine, G is guanine, and p is a phosphate group. DNA methylation may also take place on cytosine in nucleotide sequences such as CHG and CHH, where H is adenine, cytosine, or thymine. DNA methylation may also take place at, e.g., N6-methyladenine, other than cytosines. In addition, DNA methylations may further be in the form of 5-hydroxymethylcytosine, etc. In most cases, DNA methylations are induced by methylation modifications on oppolocus DNA strands or other CpG loci near DNA bases. 
     In some cases, “DNA methylation” may be used as a noun, referring to a methylated DNA fragment. 
     In the present disclosure, “demethylation” refers to biochemical erasure of the methylation modification to the C base of the CpG locus on the original DNA fragment. During human embryonic development, the erasure process is realized mainly by specifically catalyzing the oxidization of 5-methylcytosine by a TET family oxidase to form 5-hydroxymethylcytosine, 5-formylcytosine, and 5-carbonylpyrimidine in this order, then forming uracil through the catalytic deamination reaction of APOBEC family enzymes, and finally erasing the uracil at this locus through replication and correction by DNA polymerases, and replacing it with the original cytosine. 
     In the present disclosure, “de novo methylation” refers to a process of DNA methylation occurring on a DNA fragment that does not originally have any methylation modification. In particular, this process is not the same as the DNA methylation induced by the methylation modification to the oppolocus DNA strand caused by semi-conservative replication. 
     In the present disclosure, “hyper-methylation” means that more than 50%, preferably more than 90%, more preferably more than 95% of the C bases at CpG loci on a DNA fragment are modified with methylation. In the present disclosure, “hyper-methylation” and “high methylation” have the same meaning and are interchangeable. 
     In the present disclosure, “hypo-methylation” means that less than 50%, preferably less than 10%, more preferably less than 5% of the C bases at CpG loci on a DNA fragment are modified with methylation. 
     In the present disclosure, “DNA methylated locus” refers to a single or multiple base position(s) at which DNA methylation modifications may occur, for example, a CpG locus, a CHG locus, or a CHH locus. In some instances, DNA methylated loci are equivalent to CpG loci. 
     In the present disclosure, “DNA differentially methylated locus”, also known as a “DNA methylation modification difference locus”, refers to a single base position where the degrees of DNA methylation modifications are different in two groups of biological samples, for example, a CpG locus, a CHG locus, or a CHH locus. 
     In the present disclosure, “DNA differentially methylated region”, also known as a “DNA methylation difference region” or “DNA methylation modification difference region”, refers to a genomic region consisting of a plurality of adjacent base positions where the degrees of DNA methylation modifications are different in two groups of biological samples. Of these, the distance between any two adjacent base positions does not exceed 20,000 nucleotides (bases). 
     In the present disclosure, “DNA methylation modification” may be expressed as a single base methylation modification, or may be expressed as a mean of methylation modifications of multiple bases on a continuous region, or may be expressed as a methylation haplotype, or may also be expressed as a methylation monosomy. 
     In the present disclosure, “DNA methylation modification level” may be described by overall quantitative parameter p or by the abundance of the methylation haplotype. 
     In the present disclosure, the overall quantitative parameter p of the DNA methylation modification level may be expressed as a mean methylation modification level of C bases, namely.

     The above-mentioned formula is applied to either a single base or a genomic region consisting of a plurality of adjacent bases. 
     In the present disclosure, “methylation haplotype”, also known as “methylation monosomy”, refers to a combination of methylation modifications at two or more consecutive C-base loci on a single DNA fragment. Due to the relevance of the DNA methylation modifications on the same chromosome (DNA strand), the methylation modifications to a plurality of adjacent C-base loci may be correlated with one another, forming a certain fixed form. Therefore, the DNA methylation haplotype is an interlocking pattern of DNA methylation modifications on the same chromosome. 
     In the present disclosure, “abundance of methylation haplotype” refers to the proportion of a specific methylation haplotype obtained from statistical analysis of the methylation haplotype information. That is, abundance of methylation haplotype=the number of DNA fragments matching a specific methylation haplotype/the total number of DNA fragments fully covering the genomic region with this methylation haplotype. 
     In the present disclosure, “methylated regions with a placenta-derived gestational disorder” and “differentially methylated regions (DMRs) specific to a placenta with a placenta-derived gestational disorder” share the same meaning, and can be interchangeable. 
     In the present disclosure, “Pearson correlation coefficient” can be used to measure the degree of correlation between two random variables by dividing the standard deviation of the two random variables by the covariance. Pearson correlation coefficient is a value between −1 and 1. If the linear relationship between two variables is strengthened, the correlation coefficient tends to be 1 or −1. If one variable increases and the other also increases, this indicates that they are positively correlated and the correlation coefficient is greater than 0. If one variable increases but the other decreases, this indicates that they are negatively correlated and the correlation coefficient is less than 0. If the correlation coefficient is equal to 0, this indicates that they do not have a linear relationship. 
     In the present disclosure, “similarity” can be used to measure the quantitative similarity of two samples or two types of samples. In particular, it can be expressed quantitatively as the probability that a sample is surely from a certain type of specific samples, as calculated by a statistical principle. In other words, it corresponds to the probability that a sample randomly selected from a group of samples of a specific type is equivalent to a given target sample. 
     In the present disclosure, “higher similarity” or “significantly higher” means that when the probability that a sample is from the specific samples of type A rather than from the specific samples of another type (e.g., rather than from the specific samples of type B) exceeds 90%, preferably exceeds 95%, more preferably exceeds 99%, the statistic value of similarity is significantly higher than expected; “lower similarity” or “significantly lower” means that when the probability that a sample is from the specific samples of type A rather than from the specific samples of another type (e.g., rather than from the specific samples of type B) is less than 10%, preferably less than 5%, more preferably less than 1%, the statistic value of similarity is significantly lower than expected. 
     In the present disclosure, the method for measuring the similarity between two samples may be selected from Bayesian analysis, correlation, binomial distribution, beta distribution, negative binomial distribution, hypergeometric distribution, Normal distribution, Poisson distribution, Komolgorov-Smirnov test (KS test), and Shapiro-Wilk test. The method for measuring the proportion of sample similarity (i.e., the probability that a sample is more likely from the specific samples of type A rather than the specific samples of type B) may be selected from likelihood ratio test and chi-square test. Without loss of generality, a person skilled in the art should be easily aware that such analysis may be conducted by any other appropriate mathematics statistics method based on the specific DNA methylated markers and principles and methods of statistics provided herein. 
     In the present disclosure, “EP-007 probe or probe set” is composed of a series of end-labeled DNA fragments of about 50 bp to about 70 bp in length, which is capable of capturing and enriching the genomic regions listed in Attached List 1 herein. For a specific region as listed in the Attached List 1, the EP-007 probe or probe set includes a combination of whole-genome methylation or demethylation modifications to all CpG loci over this specific region. Namely, for any CpG locus on any region as listed in the Attached List 1, the EP-007 probe or probe set includes not only complementary sequences when the locus is an unmethylated cytosine, but also complementary sequences when the locus is a methylated cytosine. Exemplarily, the probes in the “EP-007 probe or probe set” used herein are 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, or 70 bp in length. 
     In one embodiment of the present disclosure, the DNA methylation status may be analyzed by other techniques, such as microarray, real-time PCR, digital real-time PCR, and mass spectrometry (Plongthongkum et al., Nature Reviews Genetics, 2014, 15 (10):647-61; Consortium et al., Nature Biotechnology, 2016, 34 (7):726). A person skilled in the art should be easily aware that, based on the specific DNA methylated markers provided herein, any method or reagent that can be used to detect the DNA methylation status may be used to detect, monitor, and/or predict whether a subject has a placenta-derived gestational disorder. 
     The bisulfite conversion-based methylation detection method has become a conventional technique for detecting the DNA methylation status, and is well known to a person skilled in the art. In one specific embodiment of the present disclosure, the EZ DNA Methylation-Goldbisulfite conversion kit from the Zymo Research Corporation is used as a reagent for detecting the DNA methylation status, to enable the bisulfite conversion of the sample DNA. 
     In one embodiment of the present disclosure, the inventors have discovered that it is possible to compare the methylation regions in the placental sample to be tested with those in the placenta in control pregnancy, determine a mean methylation level or an abundance of methylation haplotype in a differentially methylated region specific to the placenta with a particular placenta-derived gestational disorder in the sample to be tested by comparing the placental sample to be tested with the placental sample from a pregnancy with or without the particular placenta-derived gestational disorder, and then analyze the similarity between the placental sample to be tested and the placenta with or without the particular placenta-derived gestational disorder based on the mean methylation level or the abundance of methylation haplotype, thereby determining whether the source of the placental sample to be tested is related to the particular placenta-derived gestational disorder. 
     In one specific embodiment of the present disclosure, the inventors have discovered that compared with the placenta in the control pregnancy, the placenta with the placenta-derived gestational disorder has a series of differentially methylated regions (DMRs) specific to the placenta with the placenta-derived gestational disorder, namely, the methylation regions with the placenta-derived gestational disorder. 
     In another embodiment of the present disclosure, the inventors have discovered that by comparing the mean methylation levels in the differentially methylated regions (DMRs) specific to the placenta with the placenta-derived gestational disorder, the placenta in normal pregnancy can be distinguished from the placenta from a pregnant woman with the placenta-derived gestational disorder selected from: gestational diabetes (GDM), twin-to-twin transfusion syndrome (TTTS), fetal intrauterine growth restriction, gestational hypertension (GHT), eclampsia, preeclampsia (PE), severe preeclampsia, secondary preeclampsia, atypical preeclampsia, or HELLP syndrome, thereby determining whether the subject has the placenta-derived gestational disorder. 
     In one specific embodiment of the present disclosure, the placenta-derived gestational disorder is preeclampsia. Exemplarily, according to the relative methylation levels (compared, in the same region, with the regional methylation levels in the placenta in control pregnancy), the differentially methylated regions (PE-DMRs) specific to the preeclamptic placenta may be classified into preeclampsia-specific hyper-methylated regions (PE-hyper-DMRs, i.e., the genomic regions with an elevated methylation modification level in the preeclamptic placenta) and preeclampsia-specific hypo-methylated regions (PE-hypo-DMRs, i.e., the genomic regions with a decreased methylation modification level in the preeclamptic placenta). Furthermore, the inventors have discovered that by comparing the mean methylation levels in PE-DMRs, it is possible to distinguish germ cells or embryonic tissues at different developmental stages, including, but not limited to, ovum, sperm, 8-cell cleavage stage, morula, blastocyst-stage inner cell mass, and fetus at 6 weeks of gestation. 
     In one embodiment of the present disclosure, the inventors have further studied PE-DMRs and discovered that PE-hyper-DMRs are mostly distributed in intergenic regions and introns. Moreover, the inventors have discovered a higher proportion of PE-hyper-DMRs on a series of human endoretroviruses (ERVs) in intergenic regions or introns. 
     In one specific embodiment of the present disclosure, ERV enriching preeclampsia-specific hyper-methylated regions includes LTR12C, LTR12E, LTR13A, HERVE-int, LTR12D, and LTR13. In a more specific embodiment, the ERV significantly enriching preeclampsia-specific PE-hyper-DMRs is LTR12C. 
     In spite of not wishing to be bound by a single theory, there are PE-hyper-DMRs that are in a hypo-methylation status in  Homo sapiens  spermatoblasts, but are in a hyper-methylation status in the homologous regions in Pan troglodytes. That is, the PE-hyper-DMRs are enriched in the hypo-methylated regions specific to  Homo sapiens  gametes. Furthermore, the chromatin accessibility to the PE-hyper-DMRs are specifically increased at the 8-cell stage of  Homo sapiens  embryonic development, that is, the PE-hyper-DMRs are enriched in the functional regions of the genome that play important roles in the specific stage of embryonic development. 
     In one embodiment of the present disclosure, the inventors have discovered that in the preeclamptic placenta, a change in the methylation status of LTR12C is strongly correlated with the change in the chromatin accessibility status of its surrounding genes. 
     Moreover, PE-hypo-DMRs are enriched in introns of functional genes, introns of non-coding RNAs, 5′-untranslated regions, 3′-untranslated regions, and downstream regions of genes. 
     In one embodiment of the present disclosure, the inventors have discovered that PE-hypo-DMRs are significantly enriched in the de novo methylation region of the placental lineage, suggesting that the preeclamptic placenta is significantly defective in the course of de novo methylation. Furthermore, the chromatin accessibility to the PE-hypo-DMRs is specifically increased at the morula stage and blastocyst stage and in the placenta during the  Homo sapiens  embryonic development, and the expression of their surrounding genes is strongly increased at these stages of embryonic development, particularly in the differentiation process of extravillous trophoblasts (EVTs). That is, PE-hypo-DMRs are enriched in functional regions of the genome that play important roles in cell differentiation and placental development. 
     In another embodiment of the present disclosure, the inventors have discovered that in the placental tissue, there are strongly correlated CpG loci in the preeclampsia-specific methylation regions. The methylation modifications carried on DNA fragments, from which such type of genomic regions are derived, can form a characteristic combination, i.e., a preeclampsia-specific methylation haplotype. The inventors have further discovered that the methylation patterns of the preeclampsia-specific methylation haplotypes differ markedly and consistently between the preeclamptic placenta and the placenta in control pregnancy. Meanwhile, such kind of methylation haplotypes is not present in the plasma of normal non-pregnant women. 
     In another embodiment of the present disclosure, the inventors have discovered that the preeclampsia-specific methylation haplotype may be detected in and only in cfDNA fragments in the plasma of pregnant women afflicted with preeclampsia. 
     In another embodiment of the present disclosure, the inventors have discovered that the difference in the abundance of such kind of methylation haplotypes in the plasma of pregnant women is in fact an indicator for the difference in the developmental and health conditions of placentas. To wit, it is possible to determine whether a subject pregnant woman has a placenta-derived disease by comparing the abundance of methylation haplotype in the plasma of the subject pregnant woman with that in the placenta with the placenta-derived gestational disorder and in the placenta in control pregnancy. 
     In one specific embodiment of the present disclosure, when the abundance of the preeclampsia-specific methylation haplotype in plasma is significantly lower than the abundance in plasma of pregnant women with preeclampsia in a statistics sense and the abundance of the methylation haplotype specific to the control pregnancy is significantly higher than the abundance in plasma of pregnant women with preeclampsia in a statistics sense, the placenta may be considered to be in good developmental and health conditions. However, when the abundance of the preeclampsia-specific methylation haplotype is relatively increased, the placenta may be considered to be dysplastic, and placental-derived diseases such as preeclampsia are more likely to occur. Thus, the preeclampsia-specific methylation haplotype discovered by the inventors may be used to predict the risk of preeclampsia. 
     In one embodiment of the present disclosure, the inventors have discovered that by comparing the sample to be tested with the placental samples with or without the placenta-derived gestational disorder to determine the mean methylation level of the sample to be tested in the differentially methylated regions specific to the placenta with the placenta-derived gestational disorder; and then by comparing the similarity between the detection results of the sample to be tested and the placental sample without the placenta-derived gestational disorder, it is possible to determine whether the subject has the placenta-derived gestational disorder. 
     To be specific, if the similarity between the detection results is lower (i.e., the statistic value of similarity is significantly lower than expected), or the similarity between the detection results of the sample to be tested and the placental sample with the placenta-derived gestational disorder is higher (i.e., the statistic value of similarity is significantly higher than expected), the subject has the placenta-derived gestational disorder. If the similarity between the detection results of the sample to be tested and the placental sample without the placenta-derived gestational disorder is higher (i.e., the statistic value of similarity is significantly higher than expected), or the similarity between the detection results of the sample to be tested and the placental sample with the placenta-derived gestational disorder is lower (i.e., the statistic value of similarity is significantly lower than expected), the subject does not have the placenta-derived gestational disorder. 
     The higher similarity (or significantly higher) or the lower similarity (or significantly lower) is determined by the following criterion: if the probability that this sample is from a certain group of the samples is less than 10%, preferably less than 5%, more preferably less than 1%, the similarity between the detection results is considered to be lower; if the probability that this sample is from a certain group of the samples is more than 90%, preferably more than 95%, more preferably more than 99%, the similarity between the detection results is considered to be higher. 
     In another embodiment of the present disclosure, the inventors have discovered that by comparing the detection result of the DNA methylation haplotype in the sample to be tested or of the abundance of the DNA methylation haplotype with the detection result of a DNA methylation haplotype in a placental sample with or without the placenta-derived gestational disorder or of the abundance of the DNA methylation haplotype, it is possible to determine whether the subject has the placenta-derived gestational disorder. 
     To be specific, if the similarity between the detection results of the sample to be tested and the placental sample without the placenta-derived gestational disorder is lower (i.e., the statistic value of similarity is significantly lower than expected), or the similarity between the detection results of the sample to be tested and the placental sample with the placenta-derived gestational disorder is higher (i.e., the statistic value of similarity is significantly higher than expected), the subject has the placenta-derived gestational disorder. If the similarity between the detection results of the sample to be tested and the placental sample without the placenta-derived gestational disorder is higher (i.e., the statistic value of similarity is significantly higher than expected), or the similarity between the detection results of the sample to be tested and the placental sample with the placenta-derived gestational disorder is lower (i.e., the statistic value of similarity is significantly lower than expected), the subject does not have the placenta-derived gestational disorder. 
     The higher similarity (or significantly higher) or the lower similarity (or significantly lower) is determined by the following criterion: if the probability that this sample is from a certain group of the samples is less than 10%, preferably less than 5%, more preferably less than 1%, the similarity between the detection results is considered to be lower; if the probability that this sample is from a certain group of the samples is more than 90%, preferably more than 95%, more preferably more than 99%, the similarity between the detection results is considered to be higher. 
     In one embodiment of the present disclosure, the inventors have developed a prediction model for the risk of preeclampsia using the plasma from 22 pregnant women at 11 to 18 gestational weeks. Specifically, cfDNAs are extracted from the plasma of pregnant women; the cfDNA fragments treated with sulfite are captured by a specific probe; and the DNA fragments containing the preeclampsia-specific methylation regions are enriched and subjected to high-throughput sequencing. The similarity between the cfDNA sample and the preeclamptic placenta and the placenta in control pregnancy is calculated to predict the risk of preeclampsia. 
     In one embodiment of the present disclosure, the risk of preeclampsia can be predicted by calculating the Pearson correlation coefficient between the cfDNA sample and any type of placental samples. 
     In one specific embodiment of the present disclosure, the Pearson correlation coefficient can be used to describe the degree of correlation between the preeclampsia-specific methylation haplotype in cfDNA from a subject pregnant woman and the placenta in control pregnancy and the preeclamptic placenta, i.e., r(CTRL) and r(PE). Further, r(CTRL) is compared with r(PE) to evaluate the risk of the subject pregnant woman being afflicted with preeclampsia during the pregnancy. If r(CTRL) &gt;r(PE), the risk of the subject pregnant woman being afflicted with preeclampsia during the pregnancy is low; if r(CTRL)&lt;r(PE), the risk of the subject pregnant woman being afflicted with preeclampsia during the pregnancy is high; if r(CTRL)=r(PE), the risk of the subject pregnant woman being afflicted with preeclampsia during the pregnancy is a grayscale critical value. 
     Furthermore, in a retrospective clinical trial of the present disclosure, the detection and statistical method has achieved a sensitivity of 97% and specificity of 89% for the detection of pregnant women with preeclampsia among 159 peripheral blood samples from pregnant women. Besides, the correlation coefficient may also be used to predict the risk of pregnant women being afflicted with gestational hypertension, preeclampsia, severe preeclampsia, and secondary preeclampsia during the pregnancy. Moreover, the correlation coefficient shows a good linear correlation with the highest systolic blood pressure during the first stage of labor for pregnant women, and this correlation coefficient may be used to predict the highest systolic blood pressure during labor. 
     In one specific embodiment of the present disclosure, the “EP-007 probe or probe set” is composed of a series of 50- to 70-bp DNA fragments labeled with biotin at the 3′-end. It has the following four types of sequences (the design principle is as shown in  FIG.  17   a    of the present disclosure): 
     1. the sequences inversely complementary to the sequences in which C is replaced with T as compared to the sequences of the genomic regions listed in Attached List 1; 
     2. the sequences in which C is replaced with T as compared to the sequences of the genomic regions listed in Attached List 1; 
     3. the sequences inversely complementary to the sequences in which C is replaced with T except at CpG loci as compared to the sequences of the genomic regions listed in Attached List 1; 
     4. the sequences in which C is replaced with T except at CpG loci as compared to the sequences of the genomic regions listed in Attached List 1. 
     In one specific embodiment of the present disclosure, the labeling may be applied at the 3′-end. 
     In one specific embodiment of the present disclosure, the labeling may include, but is not limited to, the labeling methods such as biotin labeling, avidin labeling, and fluorescent labeling, as long as the labeling enables the “EP-007 probe or probe set” to be detected by a detecting instrument. Exemplarily, in case of the fluorescent labeling, the detecting instrument is selected from fluorescence-detectable devices. 
     Since the sequences of the genomic regions listed in Attached List 1 in the present disclosure have been recited, a person skilled in the art may design a suitable EP-007 probe or probe set based on the design principle of the EP-007 probe or probe set as described above.

     Hybridization reaction: In accordance with Table 7, a hybridization system was prepared in a 200-μL PCR tube using a hybrid elution kit of non-invasive preeclampsia early screening kit, left to stand for 10 min after mixing well with vortex, and thereafter denatured in a PCR amplifier at 95° C. for 10 min. At 8 min of denaturation, the PCR tube containing 4.5 μL of probe was placed in the PCR amplifier at 95° C. to preheat the probe. After denaturation, the probe was charged into the hybridization system mixture at 47° C. After mixing with vortex, the PCR tube was placed in the PCR amplifier at 47° C. (heat dome temperature: 57° C.) and hybridized for 72 h.

This step was repeated once. The liquid waste was aspirated and discarded and 180 NL of 1×TQWS1 was added and mixed well by vibration at room temperature for 2 min before absorbing over a magnetic stand until the liquid was clear. The liquid waste was aspirated and discarded and 180 μL of 1×TQWS2 was added and mixed well by vibration at room temperature for 1 min before absorbing over a magnetic stand until the liquid was clear. The liquid waste was aspirated and discarded and 180 μL of 1×TQWS3 was added and mixed well by vibration at room temperature for 1 min before absorbing over a magnetic stand until the liquid was clear. The liquid waste was aspirated and discarded and 23 μL of TQNF reagent was added and mixed well by vibration.

       FIG.  4    shows the fragment size of the libraries captured by the SeqCap EpiGiant probe, as determined by Agilent 2100 Bioanalyzer. The size of the above fragment is about 300 bp. Specifically,  FIG.  4   a    shows the library constructed based on placenta gDNAs, which has a fragment size of about 300 bp.  FIG.  4   b    shows the library constructed based on cfDNAs in the plasma, which has a fragment size of about 300 bp. 
     Example 5: Quality Test on Data Produced by Illumina Second-Generation High-Throughput Sequencing Platform for Methylation Libraries 
     Experimental Methods and Results 
     The DNA pre-library was sequenced in accordance with the instructions of the Illumina platform kit. In the raw reads, the proportion of Q30 was greater than 80%. Samples were demultiplexed using bcl2fastq (0.2.1). According to the quality control criterion, the unknown demultiplexing fragment count was &lt;5%, and the average fragment length was &gt;160 bp. The Euler-PhiX flow was used for quality control of the PhiX library, and the criterion of acceptability was error rate &lt;0.001%. Fastqc (3.2) was used for quality control of sublibraries. The quality control criteria for libraries were as follows: Q30 &gt;80%, repeating fragments &lt;=10%, and GC ratio=30%-35%. As for the cfDNA libraries, the KS test on their fragment length distribution and that of the standard cfDNAs shows that P&gt;0.5, and the KS test on their fragment end base distribution and that of the standard cfDNAs show that P&gt;0.5. CHG&gt;THG and CHH&gt;THH were sampled and found that their conversion rates were &gt;99%.

     Experimental Methods 
     Analysis of DNA Methylation Level 
     The procedures for extraction of placenta gDNA, capture by SeqCap EpiGiant probes, and high-throughput sequencing were the same as those described in Example 1, Example 4, and Example 5. 
     Analysis of the methylation level at CpG loci: The coverage and methylation level at each CpG locus were extracted using PileOMeth (version 0.1.13). Conditions for quality control: The coverage at a single CpG locus was required to be ≥200×. Each of the methylated loci was analyzed using the R language (3.5.2) to screen out the preeclampsia-specific methylation modification loci. Each of the CpG methylation modification loci was subjected to statistical detection by the t test, and required to meet the following conditions: the distribution of its methylation modifications in preeclamptic placental samples was significantly different from that of methylation modifications in control placental samples, i.e., p&lt;0.001; at the same time, the distribution of its methylation modifications in preeclamptic placental samples was significantly different from that of methylation modifications in plasma samples from healthy non-pregnant women, i.e., p&lt;0.001. The methylation levels at the CpG loci, obtained from the above analysis, were significantly and consistently different among different groups of samples, i.e., groups of preeclamptic placentas, control gestational placentas, and plasma from non-pregnant women. The CpG loci obtained from the above analysis were methylation modification loci specific to preeclamptic placentas (for the details, see Attached List 1). 
     The regions where the methylation modification loci specific to preeclamptic placentas were located were combined, and the methylation levels were averaged across the whole region. In control placentas and preeclamptic placentas, each of the regions was analyzed using the R language (3.5.2), and the mean methylation level of each of the regions was detected by the t test. 
     Experimental Process for Chromatin Accessibility Sequencing Analysis (ATAC-Seq) 
     Tissue homogenization: 20 mg of frozen tissues were weighed and put in a pre-cooled glass homogenizer, to which 1 ml of pre-cooled 1×HB buffer (as listed in Table 10, in which the 1×HB buffer was further prepared based on the 1.022×HB buffer listed in Table 9) was added, followed by grinding the tissues. The ground tissue homogenates were filtered through a 70-μm cell strainer and transferred into a low-adsorption tube, and centrifuged at 4° C. for 5 min. The supernatant was discarded. The tissue homogenates were re-suspended by adding a fresh HB buffer.

     Iodixanol gradient centrifugation: An equal volume of 50% iodixanol was added to the re-suspension to prepare 30% and 40% iodixanol, and construct a density gradient centrifugation system for nuclei enriched on 25%/30%/40% iodixanol, which was centrifuged at 3000 rcf at 4° C. for 20 min. After centrifugation, the nuclear layer at the interface of 30% and 40% iodixanol was aspirated. The RSB buffer (Table 11) was added to dilute the nuclei.

     Tn5 transposase digestion-based library construction and purification: After centrifugation at 500 rcf at 4° C. for 10 min, the Tn5 transposase digestion was carried out according to the instructions of the VazymeTD501-02 TruePrepDNALibraryPrepKit. The enzyme-digested product was purified according to the Zymo D4061 Oligo Clean &amp; Concentrator kit. The purified product was subjected to Index PCR according to TruePrep Index Kit V2 for Illumina. The PCR product was subjected to library purification with XP beads. 
     ATAC-Seq Data Analysis 
     The coverage was extracted with deeptools (version 3.3.0). R Software (version 3.5.2) was used to analyze the coverage values of transcription factors and TSS region. The peak of the accessible chromatin enrichment region was analyzed using macs2 Software (version 2.2.4) and Genrich Software (version 0.6). For the peaks of the accessible chromatin enrichment regions extracted from the eclamptic placenta and the control placenta, diffBind and NarrowPeaks (R language package from Bioconductor) were used to analyze their differential regions and perform enrichment analysis (statistically analyzing the data using the R language). 
     Experimental Results 
     Screening of Preeclampsia-Specific DNA Methylated Regions 
     As shown in  FIG.  5   a   , the x-axis represents the mean methylation level of the placenta-specific differentially methylated regions in a placenta in normal pregnancy, and the y-axis represents the mean methylation levels of the same region in preeclamptic placentas. The light-gray dots were concentrated on the straight line y=x, indicating that the mean methylation levels of these methylated regions were consistent in the preeclamptic placentas and in the placentas in normal pregnancy, i.e., non-differential regions. The distribution of black dots deviated obviously from the straight line y=x, indicating that there were differentially methylated regions with significantly statistical differences in the preeclamptic placentas and in the placentas in normal pregnancy. 
     The density distribution curves in  FIG.  5   b    depict the differentially methylated regions of  FIG.  5   a   . Therefore,  FIG.  5   b    shows the density distribution curves of the non-differential regions (light gray) and the methylated regions with significantly statistical differences (dark gray) as shown in  FIG.  5     a.    
     In other words, as shown in  FIG.  5   , the comparison between the whole-genome methylation levels in the preeclamptic placentas and in the placentas in control pregnancy revealed that there were a large number of preeclampsia-specific differentially methylated regions (PE-DMRs), which could be classified into, according to the difference in methylation levels of PE-DMRs, preeclampsia-specific hyper-methylated regions (PE-hyper-DMRs) and preeclampsia-specific hypo-methylated regions (PE-hypo-DMRs) (for the details, see Attached List 2). 
     As shown in  FIG.  6   , PE-DMRs, when aligned to the whole genome, were found to be concentrated in the gene regulatory regions, such as non-coding transcription regions (5′UTR/3′UTR), intergenic regions, introns, and some of exon regions. A further statistical analysis of enrichment showed that PE-hypo-DMRs were significantly enriched in introns, 5′UTR/3′UTR, and intron regions of non-coding RNAs; while PE-hyper-DMRs were mostly distributed in intergenic regions and intron regions, their distribution patterns were random. 
     As shown in  FIG.  7   , the alignment of the PE-hyper-DMRs with the transposable elements (TEs) in human genome revealed that the PE-hyper-DMRs were significantly enriched in LTR12 family transposons. In particular, about 30% of LTR12C transposons contained PE-hyper-DMRs. 
       FIG.  8   a    shows the DNA methylation patterns in Pan troglodytes and  Homo sapiens  spermatoblasts.  FIG.  8   b    shows the comparison of chromatin accessibility to the placenta in control pregnancy and the preeclamptic placenta.  FIG.  8   c    shows the methylation patterns of the region in the placenta in control pregnancy and the preeclamptic placenta. 
     To wit, by comparing the DNA methylation modification levels of the LTR12C regions with the preeclampsia-specific hyper-methylation characteristics or the homologous regions thereof in the preeclamptic placentas, the placentas in control pregnancy, the  Homo sapiens  spermatoblasts, and the Pan troglodytes spermatoblasts, it was found that there was LTR12C in the preeclamptic hyper-methylated region, and this region was in a hyper-methylation status in Pan troglodytes spermatoblasts while it was in a hypomethylation status in  Homo sapiens  spermatoblasts ( FIG.  8   a   ). That is, the hypo-methylated LTR12C specific to  Homo sapiens  spermatoblasts was in a hyper-methylation status in preeclamptic placentas ( FIG.  8   c   ). The DNA methylation status of the hypo-methylated LTR12C specific to  Homo sapiens  spermatoblasts was altered in preeclamptic placentas, accompanied by the change in chromatin accessibility ( FIG.  8   b   ). 
     As shown in  FIG.  9   , the analysis of the whole-genome chromatin accessibility to different developmental stages (2-cell stage, 4-cell stage, 8-cell stage, inner cell mass at the blastocyst stage, embryonic stem cell, and placenta) of an embryo showed that the chromatin accessibility to the genes in vicinity of the preeclamptic hyper-methylated region was specifically increased at 8-cell stage. 
     Example 7: Screening of De Novo Methylation Regions Specific to Placental Lineage 
     Experimental Methods and Results 
     Analysis of methylation levels at CpG loci: The coverage and methylation level were extracted from each of CpG loci using PileOMeth (version 0.1.13). Conditions for quality control: the coverage at a single CpG locus was required to be ≥200×. Each of the methylated loci was analyzed using the R language (3.5.2) to screen out the preeclampsia-specific hyper-methylation modification locus, which was in a hypomethylation status in leukocyte of healthy non-pregnant women. Each of the CpG methylation modification loci was subjected to statistical detection by the t test, and required to meet the following conditions: the distribution of its methylation modifications in the placental sample in control pregnancy was significantly different from that of methylation modifications in the sample from leukocyte of healthy non-pregnant women, i.e., p&lt;0.001. 
     Based on the differentially modified methylation locus screened by the above analysis, the regions where it was located were combined, and the methylation levels were averaged across the whole region, thereby screening out a placenta-specific hyper-methylated region. Similarly, by comparing the loci with differentially methylated modifications in DNAs from HUVEC (a differentiated human-derived placental cell line) and hESC1 (an undifferentiated human-derived embryonic stem cell line), it was possible to screen out the locus that was hyper-methylated in HUVEC and hypo-methylated in hESC1 could be screened out. The differentially methylated loci were statistically detected by the t test, which had to satisfy p&lt;0.001. The regions where differentially modified methylation loci screened were located were combined, and the methylation levels were averaged across the whole region, thereby screening out a HUVEC-specific hyper-methylated region. The intersection of the placenta-specific hyper-methylated region and HUVEC-specific hyper-methylated region was the de novo methylation region specific to placental lineage.

     Single cell RNA sequencing database of  Homo sapiens  placental tissues (E-MTAB-6701, E-MTAB-6678, E-MTAB-7304). 
     Experimental Methods and Results 
     Placental de novo methylation regions and PE-DMRs were intersected to sort out the preeclampsia-specific differentially methylated regions that executed the placental de novo methylation, i.e., ExE-DN PE-DMRs, and the preeclampsia-specific differentially methylated regions that did not execute the placental de novo methylation, i.e., Not-ExE-DN PE-DMRs. 
       FIG.  9    shows the mean regional methylation levels of the preeclampsia-specific differentially methylated regions that executed the placental de novo methylation, ExE-DN PE-DMRs (dark gray) and the preeclampsia-specific differentially methylated regions that did not execute the placental de novo methylation, Not-ExE-DN PE-DMRs (light gray). The y-axis represents the log value of the ratio of the mean regional methylation level in the preeclamptic placenta to that in the placenta in normal pregnancy. That is, y=0 represents that in a certain region, there is no difference between the mean methylation levels in the preeclamptic placenta and in the placenta in normal pregnancy. 
     To wit, the methylation level of ExE-DN PE-DMRs in the preeclamptic placenta was significantly decreased in comparison to the placenta in normal pregnancy ( FIG.  10   ). By aligning the preeclampsia-specific hypo-methylated regions with the placental de novo methylation regions, it was found that 52% of the preeclampsia-specific hypo-methylated regions overlapped the placental de novo methylation regions, so the preeclamptic placentas were obviously defective in the course of de novo methylation to the placental lineage. Two examples of preeclampsia-specific de novo methylation defects in the placental lineage were as shown in  FIGS.  11  and  12   . The analysis of the whole-genome chromatin accessibility to different developmental stages (2-cell stage, 4-cell stage, 8-cell stage, inner cell mass at the blastocyst stage, embryonic stem cell, and placenta) of an embryo showed that the chromatin accessibility to the genes in vicinity of the preeclampsia-specific hypo-methylated region was specifically increased in morula, blastocyst, or placenta, as shown in  FIG.  13   . 
     Time-series analysis of single-cell RNA expression: The RNA expression data were extracted using Monocle (version 0.2.0). The data were subjected to dimensionality reduction by the principal component analysis method (reduce_dimension function, Monocle) and the UMAP method. For each cell, the mean expression levels of its homologous genes (genes within the range of 50 kbp base pairs near the PE-hypo-DMR or PE-hyper-DMR position) were calculated as the expression levels of PE-hypo-DMR genes and PE-hyper-DMR genes. 
     By analyzing the gene expression levels during the differentiation of placental villous cytotrophoblasts (VCTs) into syncytiotrophoblasts (SCTs) or extravillous trophoblasts (EVTs), it was found that, as shown in  FIG.  14   , the genes in vicinity of the preeclampsia-specific hypo-methylated regions were mostly specifically expressed in EVT cells, while the genes in vicinity of the preeclampsia-specific hyper-methylated regions were mostly specifically expressed in VCT cells.

     Experimental Methods and Results 
     The experimental methods for performing the DNA methylation sequencing on placentas and the data analysis were the same as those described in Example 4, Example 5, and Example 6. 
     PE-hyper-DMRs and PE-hypo-DMRs could be obtained through the experiments and analyses described in the above-mentioned examples. Statistical analysis of the mean methylation levels of the above-mentioned regions in the methylation databases of human ovum, sperm, 8-cell cleavage stage, morula, inner cell mass at the blastocyst stage, and fetuses at 6 gestational weeks showed that the early embryonic development process following the gametogenesis involved a process of from extensive whole-genome demethylation (represented by 8-cell cleavage stage, morula, blastocyst) to de novo methylation (represented by normal placenta and embryo). On the trajectory formed in the course of epigenetic changes, epreeclamptic placentas could be well distinguished from early embryos/fetuses based on the mean methylation levels of the preeclampsia-specific hyper-methylated regions and hypo-methylated regions. 
       FIGS.  15   a  and  15   b    show the mean methylation levels of the preeclampsia-specific hyper-methylated and hypo-methylated regions in embryos (or tissues) at different developmental stages and placentas with different pregnancy complications, respectively.  FIG.  15   c    shows a scatter plot drawn for germ cells or embryonic tissues at different developmental stages with the mean methylation level of the preeclampsia-specific hyper-methylated regions as the x-axis and the mean methylation level of the preeclampsia-specific hypo-methylated regions as y-axis. The preeclamptic placentas, placentas without the placenta-derived gestational disorder, sperms, ova, 8-cell stage, morula, and blastocyst could be well distinguished. 
     To wit, as shown in  FIG.  15   , the result further demonstrated that PE-hyper-DMRs and PE-hypo-DMRs were specific to preeclamptic placentas.

     (All of the above placentas were collected from Peking University Third Hospital, Clinical Research Ethics Approval Document No.: IRB00001052-16009.) 
     Experimental Methods and Results 
     The experimental methods for performing the DNA methylation sequencing on gestational placentas with preeclampsia, gestational hypertension, gestational diabetes, and twin-to-twin transfusion syndrome, and placenta in normal pregnancy as well as the data analyses were the same as those described in Example 4 and Example 6. 
     PE-hyper-DMRs and PE-hypo-DMRs could be obtained through the experiments and analyses described in the above-mentioned examples. Statistical analysis of the mean methylation levels of the above regions in the placentas with gestational hypertension, gestational diabetes, and twin-to-twin transfusion syndrome, placentas without the placenta-derived gestational disorder, and preeclamptic gestational placentas showed that the mean methylation levels of the preeclampsia-specific hyper-methylated regions and hypo-methylated regions could be used to distinguish different pregnancy complications ( FIG.  15   c   ). Therefore, there were specific methylation modification differences in the PE-hyper-DMRs and PE-hypo-DMRs in preeclamptic placentas.

     (All of the above samples were collected from Guangdong Maternal and Child Health Hospital, Clinical Research Approval No. YL No. [201701044].) 
     Experimental Methods and Results 
     Extraction of placental tissue gDNA/plasma cfDNA and construction flow of DNA library were roughly the same as those described in Example 1, Example 2, Example 4, and Example 5. 
     Methylation haplotypes were extracted within the preeclampsia-specific differentially methylated regions obtained from the above analysis. Each of the haplotypes was analyzed using the R language (3.5.2) to screen out the preeclampsia-specific methylation haplotype, which was required to satisfy the condition that the frequency of this haplotype occurring in the preeclamptic placenta was at least 20 times that in the control placenta, or that the frequency of this haplotype occurring in the control placenta was at least 20 times that in the preeclamptic placenta. 
     The screened methylation haplotypes were listed in Table 3. There were significant and consistent differences in the frequencies of the preeclampsia-specific methylation haplotypes listed in this table occurring in the control gestational placentas and preeclamptic placentas, e.g., as shown in  FIG.  16   .  FIGS.  16   a  and  16   b    show the methylation haplotypes in the preeclampsia-specific hyper-methylated region and hypo-methylated region, respectively.

     Experimental Materials 
     Synthesized EP-007 probe or probe set; 
     KAPA double-strand DNA library kit (KAPA HTP Lib PrepKit, KK8235); 
     Agencourt AMPure XP beads (Beckman, A63882); 
     Dynabeads™ M-270 streptavidin (Thermo Fisher Scientific, 65306). 
     Experimental Methods and Results 
     As shown in  FIG.  17   a   , the EP-007 probe or probe set was designed based on the following basic principle: The probe was composed of several sequences that were 59 bp in length and complementary to the sequences of the methylation haplotype-specific loci after sulfite sequencing. For each of the CpG loci of each preeclampsia-specific methylation haplotype, one methylated (G) probe and one unmethylated (A) probe corresponding to this locus would be synthesized. The two probes covering adjacent loci contained 40-bp overlapping sequences. The probes had a biotin label at the 3′-end. 
     Probe design was conducted on the genomic region where the preeclampsia-specific methylation haplotypes (Attached List 3) obtained from the above analysis were located to synthesize a DNA probe complementary thereto (Twist Inc., U.S.A.). As shown in  FIG.  17   a   , a 59-bp DNA complementary strand was basically designed. 
     Exemplarily, in the present example, the sequence of the target region desired to be detected was:

     Example 13: Optimization of Hybridization Time and Hybridization and Eluting Temperatures of EP-007 Probe or Probe Set 
     Experimental Materials 
     500 ng of pre-library product for methylation library construction; 
     Hybrid Elution Kit of Non-Invasive Preeclampsia Early Screening Kit (Euler Genomics, EU-TQ-MV1); 
     Agencourt AMPure XP beads (Beckman, A63882); 
     Dynabeads™ M-270 streptavidin (Thermo Fisher Scientific, 65306). 
     Experimental Methods 
     The experimental methods were basically the same as those described in Example 4. 
     Experimental Results 
     Hybridization and eluting temperatures 
       FIGS.  18   a  and  18   b    show the comparisons of the on target rates and the mean coverage in the sequencing results obtained at different combinations of the hybridization temperatures (47° C., 56° C., and 65° C.) and the eluting temperatures (47° C., 56° C., and 65° C.), respectively. The circle represents hybridization at 47° C., the square represents hybridization at 56° C., and the triangle represents hybridization at 65° C. 
     By comparing the on target rates and the mean coverage in the sequencing results of the library products at different combinations of the hybridization temperatures (47° C., 56° C., and 65° C.) and the eluting temperatures (47° C., 56° C., and 65° C.), it was concluded that the capture effect was optimal in case of hybridization at 56° C. and elution at 65° C. That is, the on target rate was greater than 30% (as shown in  FIG.  18   a   ) and the mean coverage was the highest in case of the same data size (as shown in  FIG.  18   b   ). 
     Hybridization Time 
       FIG.  19    shows the on target rates of the library products when hybridized at the eluting temperature of 56° C. for different hybridization time (4 h, 8 h, 12 h, 24 h, 36 h, 48 h, and 60 h). It was found that the on target rate reached a sequencing result of greater than 30% when the hybridization time was 12 h. 
     The results show that the on target rate of greater than 30% may be obtained when the hybridization time is 12 h or longer.

     Dynabeads™ M-270 streptavidin (Thermo Fisher Scientific, 65306). 
     Experimental Methods 
     The experimental methods were basically the same as those described in Example 4. 
     Experimental Results 
       FIG.  20    shows the fragment size distribution of the library after probe capture as determined by Agilent 2100 Bioanalyzer. The peaks at 35 bp and 10,380 bp are DNA molecular markers.  FIG.  20   a    shows the fragment size of the library constructed based on placenta gDNA, and  FIG.  15   b    shows the fragment size of the library constructed based on cfDNA in plasma. 
     That is to say, from 500 ng of pre-library for methylation library construction, 2.98 ng/μL of library could be enriched after capture with the EP-007 probe or probe set. Determined by Agilent 2100 Bioanalyzer, the fragment size of the library constructed based on placenta gDNA and the fragment size of the library constructed based on cfDNA in plasma were both about 300 bp, as captured with the EP-007 probe or probe set.

     Experimental Methods and Results 
     The plasma from 22 pregnant women was subjected to experiments in molecular biology and analysis of the DNA methylation level. The experimental methods were the same as those described in Examples 2, 3, 5, 9, and 12. There were 6 pregnant women and 16 preeclamptic pregnant women. 
     In the control pregnancy group and the preeclampsia group, the methylation levels of each of the preeclampsia-specific methylation haplotype regions in Attached List 3 were averaged within the groups to obtain matrices M (CTRL) and M (PE), and calculate the Pearson correlation coefficients r (CTRL) and r (PE) of the control pregnancy group and the preeclampsia group by the leave-one-out method. 
     As shown in  FIG.  21   , a linear regression analysis between r(CTRL) and r(PE) and the clinical diagnosis of 22 pregnant women was made to obtain linear scores, which could be used to evaluate the degree of preeclampsia-associated placental dysplasia, that is, the degree of placental dysplasia in pregnant women afflicted with preeclampsia was high, and its linear score was high accordingly; however, the placental development of the control pregnancy was relatively good, so its linear score was low. 
       FIG.  16    shows linear scores statistically calculated by correlation and linear regression after analysis of the methylation levels of PE-DMRs. 
     Example 16: Verification of Preeclampsia Risk Prediction Model by Retrospective Clinical Samples 
     Experimental Materials 
     The experimental materials were the same as those used in Example 13, in which the peripheral blood samples drawn from a total of 159 pregnant women with preeclampsia or control pregnancy at 10 to 38 gestational weeks (Guangdong Maternal and Child Health Hospital, YL No. [201701044]). 
     Experimental Methods and Results 
     In four batches, four experimenters conducted experiments in molecular biology and analysis of haplotypes in 159 pregnant women by the same experiment methods as described in Examples 2, 3, 5, 9, and 12. 
     For the preeclampsia-specific methylation haplotype regions listed in Attached List 3, the mean methylation level of the subject in each region was calculated to obtain the matrix M (test), and the Pearson correlation coefficients between M (test) and M (CTRL) and M (PE), i.e., r (CTRL) and r (PE), were calculated, respectively. Further, r (CTRL) was compared with r (PE) to predict the risk of preeclampsia. If r (CTRL) &gt;r (PE), the risk of preeclampsia was high; if r (CTRL)&lt;r (PE), the risk of preeclampsia was low. 
     As shown in  FIG.  22   , the results show that this method may differentiate pregnant women with preeclampsia from pregnant women of control pregnancy, with the sensitivity of 97% ( 36/37) and the specificity of 89% ( 109/122). 
     Example 17: Distinguishing Different Severities of Subtypes of Preeclampsia by the Preeclampsia Risk Prediction Model 
     Experimental Materials 
     The experimental materials were the same as those used in Example 13, in which the peripheral blood samples drawn from a total of 159 pregnant women with preeclampsia or control pregnancy at 10 to 38 gestational weeks (Guangdong Maternal and Child Health Hospital, YL No. [201701044]). 
     Experimental Methods and Results 
     The experimental methods were roughly the same as those used in Example 15. For the maternal plasma from 159 subjects, the correlation between r (CTRL) and r (PE) and the clinical outcomes showed that gestational hypertension, preeclampsia, severe preeclampsia, and secondary preeclampsia could be better distinguished ( FIG.  23   ). 
     Example 18: Prediction of the Highest Pressure in the First Stage of Labor of Pregnant Women by the Preeclampsia Risk Prediction Model 
     Experimental Materials 
     The experimental materials were the same as those used in Example 13, in which the peripheral blood samples drawn from a total of 181 pregnant women with preeclampsia or control pregnancy at 10 to 38 gestational weeks (collected from Guangdong Maternal and Child Health Hospital, Clinical Research Approval No.: YL No. [201701044]). 
     Experimental Methods and Results 
     The regression statistical analysis was performed on r (CTRL) and r (PE) of 22 pregnant women and the highest pressure in the first stage of labor in the corresponding clinical outcomes, to establish a model between the similarity of the subject placenta to the control pregnancy and preeclamptic placenta and the highest systolic blood pressure in the first stage of labor of pregnant women. Then, the model was used to predict the highest systolic blood pressure in the first stage of labor of 159 pregnant women. As shown in  FIG.  24   , the highest systolic blood pressure in the first stage of labor predicted by the model was in a good linear relationship with the highest systolic blood pressure measured in clinical.
