Authors: Jin Chenyu , Jiang Hong , Lv Xiang , Sun Yu 
Published: December 2020

Abstract
Background: Patients with maxillofacial deformities require orthognathic surgeries to correct occlusion. The surgical procedure may lead to massive bleeding, which is associated with hematoma, respiratory obstruction, and asphyxia. Dexmedetomidine has been used in controlled hypotension, and may decrease blood loss in orthognathic surgery. We conducted a retrospective cohort study to evaluate the effect of dexmedetomidine on blood loss in orthognathic surgeries.Methods: The primary outcome examined was blood loss, and secondary outcomes were postoperative haemoglobin level, intraoperative heart rate, and blood pressure (T0: preoperative; T1: at incision; T2: 30 minutes after incision; T3: 60 minutes after incision; T4: 120 minutes after incision); dose of fentanyl, remifentanil, urapidil, and esmolol; operation time; incidence of allogeneic blood transfusion; crystalloid fluids volume; and colloidal fluid volume. Results: A total of 1,247 patients were included in the study, and 557 patient pairs were matched via propensity score matching. There were significant decreases in mean blood loss, heart rate at T1–T4, blood pressure at T1, remifentanil and esmolol dosage, and crystalloid fluid volume in the dexmedetomidine group compared with those in the control group. There was also a significant increase in the postoperative haemoglobin level of the dexmedetomidine group. Conclusions: Continuous infusion of dexmedetomidine can decrease blood loss in orthognathic surgery.Trial registration number: ChiCTR1800018794 (retrospectively registered)Name of registry: Chinese Clinical Trial RegistryDate of registration: 2018/10/09URL: www.chictr.org.cn/showproj.aspx?proj=30612

Abstract
BackgroundSri Lanka sustained its malaria-free status by implementing, among other interventions, three core case detection strategies. The outcomes of these strategies - namely Passive Case Detection (PCD) and, under the overall strategy of Active Case Detection (ACD), Reactive Case Detection (RACD) and Proactive Case Detection (PACD) - were analysed in terms of their effectiveness in detecting malaria infections for the period from 2017-2019.MethodsComparisons were made between the surveillance methods and between years, based on data obtained from the national malaria database and individual case reports of malaria patients. The number of blood smears examined microscopically was used as the measure of the volume of tests conducted. The yield from each case detection method was calculated as the proportion of blood smears which were positive for malaria. Within RACD and PACD, the yield of sub categories of travel cohorts and spatial cohorts was ascertained for 2019.Results A total of 158 malaria cases were reported in 2017-2019, during which between 666,325-725,149 blood smears were examined each year: PCD detected 95.6%, with a yield of 16.1 cases per 100,000 blood smears examined, making it the most effective case detection strategy, while RACD and PACD produced a yield of 11.2 and 0.3 respectively. The yield of screening the sub category of travel cohorts was very high for RACD and PACD being 806.5 and 44.9 malaria cases per 100,000 smears respectively. Despite over half of the blood smears examined being obtained by screening spatial cohorts within RACD and PACD, the yield of both was zero over all three years.Conclusions The PCD arm of case surveillance is the most effective, and therefore, has to continue and be further strengthened as the mainstay in malaria surveillance. Focus on travel cohorts within RACD and PACD should be even greater. Screening of spatial cohorts, on a routine basis and solely because people are resident in previously malarious areas, may be wasteful, except in situations where the risk of local transmission is very high, or is imminent.

Abstract
Background In order to accurately estimate leaf area index (LAI) of winter wheat by using unmanned aerial vehicle (UAV) hyperspectral imagery.Methods The UAV hyperspectral imaging data, alternating slice-wise diagonalization (ASD) spectral data, and LAI were simultaneously obtained at main growth stages (jointing stage, booting stage, and filling stage) of various winter wheat varieties under various nitrogen fertilizer treatments.The characteristic bands related to LAI were extracted from UAV hyperspectral data with different algorithms including first derivative (FD), successive projections algorithm (SPA), competitive adaptive reweighed sampling (CARS), and competitive adaptive reweighed sampling combined with successive projections algorithm (CARS_SPA). Furthermore, three modeling machine learning methods including partial least squares regression (PLSR), support vector machine regression (SVR), and extreme gradient boosting (Xgboost) were used to build LAI estimation models.Results Our results show that the correlation coefficient between UAV and ASD hyperspectral data is greater than 0.99, indicating the UAV data can be used for estimation of wheat growth information.The LAI bands selected by using different algorithms were slightly different among the 15 models built in this study. The Xgboost model using nine consecutive characteristic bands selected by CARS_SPA algorithm as input was proved to have the best performance. This model yielded identical results of coefficient of determination (0.89) for both calibration set and validation set, indicating a high accuracy of this model.Conclusions The Xgboost modeling method in combine with CARS_SPA algorithm can reduce input variables and improve the efficiency of model operation. Our results provide reference and technical support for nondestructive and rapid estimation of winter wheat LAI by using UAV.

Published: December 2020

Abstract
Background: The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor and a member of the bHLH/PAS (basic Helix-Loop-Helix/Per-Arnt-Sim) family of proteins. The AhR was cloned and characterized for its role in mediating the toxicity of dioxins. Subsequent research has identified AhR’s role in the suppression of cancer cell growth. We hypothesized that that the AhR is a molecular target for therapeutic interventions, and that activation of the AhR by select AhR modulators in cancer cells could have anti-cancer properties including cell death. This study describes the discovery and characterization of a new class of anti-cancer agents targeting the AhR.Methods: We employed two independent small molecule screening approaches to identify novel modulators of the AhR with unique anti-cancer properties. We established the AhR selective effects of a highly selective modulator in cancer cells with or without the AhR expression and identified the mechanism of action of this anti-cancer compound.Results: We report the identification of CGS-15943, uniquely selective AhR modulator, that activates AhR signaling and induces apoptosis in an AhR-dependent manner in liver and breast cancer cell models. Investigation of the downstream signaling pathway of this newly identified modulator revealed novel upregulation of Fas-ligand, which is required for AhR-mediated apoptosis.Conclusions: We identified CGS-15943 as a novel AhR-selective modulator with anti-cancer properties using two parallel and distinct screening strategies. This compound induced AhR-dependent apoptosis in multiple mouse and human liver cancer cells. Our results provide a basis for the development of a new class of anti-cancer therapeutics targeting an underappreciated molecular target, the AhR.

Abstract
Recent evidence demonstrates a pathological role for senescent cells in Alzheimer’s and Parkinson’s diseases. The present study aimed to show senescence mechanisms including senescence-associated secretory phenotype (SASP) in the familial amyotrophic lateral sclerosis (ALS) transgenic mouse model hSOD1-G93A. We evaluated, as senescence biomarkers, the expression of p16 and p21 with reverse-transcriptase quantitative PCR (RT-qPCR), immunofluorescence (IF), and immunohistochemistry (IHC), as well as the senescence-associated β galactosidase (SA-β-gal) activity in the lumbar spinal cords (LSC) of this model. As SASP markers, we quantified the mRNA levels of Il1a, Il6, Ifna, and Ifnb. Furthermore, we explored if an alteration of alternative splicing is associated with senescence phenomena in this model. Thus, we quantified the Adipor2 cryptic exon inclusion levels, a specific splicing variant repressed by TAR-DNA binding of 43 kDa (TDP-43), using RT-qPCR. Our results show an atypical senescence-profile in LSC from transgenic mice, increasing p16 and p21 mRNA and protein levels in glial cells with a mostly cytoplasmic pattern, without the canonical increase in SA-beta-gal activity in these cells. Consistent with enhanced SASP, there is an increase in Il1a and Il6 expression. Also, TDP-43 splicing activity is compromised in this ALS model, in a direct relationship with the increase in p16 expression. However, senolytic drug Navitoclax -with reported benefits in Alzheimer and Parkinson disease mouse models - does not alter the present model’s disease progression. Navitoclax neither eliminates cells expressing senescence and nor represses the expression of SASP related genes. Globally, our findings support the existence of a non-canonical profile of senescence biomarkers in the LSC of the ALS model hSOD1-G93A.

Abstract
Backgroud: In our clinical practice, we found that Tiao Jing Cu Yun Recipe (TJCYR), which was composed of Dangshen, Danshen, Danggui, Huangqi, Shudihuang, Bajitian and Yinyanghuo, had obviously enhanced the rate of pregnancy in the women with infertility. Although the application effects are desirable and satisfactory, the therapeutic mechanism of TJCYR remains poorly understood. In this study, we evaluated the effect of TJCYR on embryo implantation dysfunction (EID)-induced damage of endometrial receptivity in mice and investigated the mechanisms underlying the effect. Methods: Pregnant mice were randomly divided into six groups: Control, EID only, Progesterone (Prog)+EID, TJCYR-low-dose+EID , TJCYR-medium-dose+EID, TJCYR-high-dose+EID. Mifepristone was injected to make EID model. On the eighth day of pregnancy, the mice were sacrificed and the number of uterus-implanted blastocysts was counted. On the fourth day of pregnancy, the serum was to analyze the level of hormone by radioimmunoassay, the uterus was to analyze morphology by H&E and SEM, the combination of immunofluorescence and western blot were to identify the related proteins. Results: Compared with the EID group, the mice treated with high-dose TJCYR had a greater number of implanted sites, so we choose that dose of TJCYR as treatment in the following study. The mice treatment with TJCYR could significantly enhance the level of P 4 , and inhibite the decrease in the expression of PR that induced by EID. Compared with the EID only, the SEM showed that a marked increase in the number of well-developed pinopodes in the TJCYR treatment group. Except morphological marker, several molecules in relation to pinopodes that could be used as biomarkers. TJCYR abrogated the EID-induced weakened in those biomarkers. Additionally, the vascular density and VEGF were decreased in the EID group, it appeared severe tissue hypoxia, while TJCYR reversed that change. Compared with the control, the p-Akt and p-eNOS were decreased in EID group, accompanied with decline of NO. While TJCYR promoted the activation of Akt and eNOS, to improve the poor microvascular environment of endometrium. Conclusion: TJCYR has therapeutic potential against poor endometrial receptivity via activation of the PI3K/AKT/eNOS signaling pathway.

Published: December 2020

Abstract
Background: The identification and authentication of Chinese herbal medicines (CHMs) are directly related to their safety and efficacy in clinical treatment. However, the limited number of qualified professionals with expertise fails to meet the demand of the vast CHMs market. To make the CHMs identification more convenient and accurate, this study aimed at assessing the feasibility of the state-of-art automated machine learning (AutoML) technology in CHMs image recognition.Methods: This study presented an experimental AutoML model built on the one-stop Huawei ModelArts platform instead of a handcrafted neural network. A rich and representative dataset of 31,460 images consisting of 315 categories of commonly-used CHMs was built and used for the model creation. Furthermore, the Huawei ModelArts model was compared with a model built on the Baidu EasyDL platform using the same dataset to investigate their ability to recognize CHMs images. Three professionals were also invited to recognize images of 315 categories of CHMs.Results: During the model evaluation, high accuracies of 99.2% and 98.4% were achieved by ModelArts and EasyDL, respectively. In the subsequent held-out tests, the accuracies of ModelArts and EasyDL models were 91.2% and 91.85%, respectively. Both models performed very well individually and no statistically significant difference was found in model performance between these two platforms. However, the model-training time was only approximately 41 minutes on ModelArts platform but 118 minutes on EasyDL. The mean accuracy of the manual recognition for 315 CHMs was 97.46±1.58%.Conclusion: Results revealed that AutoML technology is a fast and simple approach and has great practical potential in the field of CHMs image recognition. Since the Huawei ModelArts platform requires less training time, we recommend it as a priority.

Abstract
Background: Cross-border malaria in Laiza City of Myanmar seriously compromised the achieving goal of malaria elimination in Yingjiang County of China. A pilot project on 3+1 strategy of joint cross-border malaria prevention and control was carried out in building border malaria buffer area in the both sides since 2017; Here, 3 was the three preventive lines in Yingjiang County to strengthen targeted measures of elimination malaria in China and +1 was a defined border area in Laiza City to adopt the integrated measures of malaria control in Myanmar. Methods: A retrospective analysis from 2015 to 2019 was conducted and the descriptive statistics was used to analyze and compare the data of malaria case detection, parasite prevalence and vector surveillance. Results: In +1 area of Myanmar from 2015 to 2019, the average of annual parasite incidence was (59.11±40.73) / 1000 and plasmodium vivax accounted for 96.27 % of total confirmed cases. After the pilot project, the annual parasite incidence, microscopic parasite prevalence rate and density of An. Minimus reduced by 89%,100% and 93.93% respectively, but the submicroscopic parasite prevalence rate was no significant difference between the two surveys (p =0.084). In Yingjiang County of China, neither indigenous nor introduced case was reported and 100% cases were imported from Myanmar since 2017. The average of annual importation rate from 2015 to 2019 was (0.47±0.15)/1000. After the pilot project, it reduced by 53% of whole county, 67% of the first preventive line, 52% of the second preventive line and 36% of the third preventive line respectively. Conclusion: The pilot project on 3+1 strategy has made remarkable effectiveness and a buffer area of border malaria was successfully established between Laiza City of Myanmar and Yingjiang County of China. The combined use and expanded coverage of indoor residual spraying and long-lasting insecticidal nets (LLINs) was more effective than only use of LLINs in reducing the transmission of plasmodium vivax caused by An. Minimus. It is necessary to adopt submicroscopic infection interventions to eliminate potential sources of infection in Laiza City of Myanmar.

Abstract
Background: Thinopyrum intermedium (2n=6x=42) is an important wild perennial Triticeae species exhibiting many potentially favorable traits for wheat improvement. Wheat-Th. intermedium partial amphiploids serve as a bridge to transfer desirable genes from Th. intermedium into common wheat. Results: Three octoploid Trititrigia accessions (TE261-1, TE266-1, and TE346-1) with good resistances to stripe rust, powdery mildew and aphids were selected from hybrid progenies between Th. intermedium and the common wheat variety ‘Yannong 15’ (YN15). Genomic in situ hybridization (GISH), fluorescence in situ hybridization (FISH) and multicolor GISH (McGISH) analyses demonstrated that the three octoploid Trititrigia possess 42 wheat chromosomes and 14 Th. intermedium chromosomes. The 14 alien (Th. intermedium) chromosomes belong to a mixed genome consisting of J-, JS- and St-genome chromosomes rather than a single J, JS or St genome. Different types of chromosomal structural variation were also detected in the 1A, 6A, 6B, 2D and 7D chromosomes via FISH, McGISH and molecular marker analysis. The identity of the alien chromosomes and the variationes in the wheat chromosomes in the three Trititrigia octoploids were also different. Conclusions: The wheat-Th. intermedium partial amphiploids possess 14 alien chromosomes which belong to a mixed genome consisting of J-, JS- and St- chromosomes, and 42 wheat chromosomes with different structural variations. These accessions could be used as genetic resources in wheat breeding for the transfer of pest resistance genes from Th. intermedium to common wheat.

Abstract
Background: Insulin resistance (IR) and inflammation are the potential mechanism linking obesity and cardiometabolic risk. The aim of this work was to examine the joint relations of obesity and metabolic status with IR and chronic inflammation level among Chinese adult twins.Methods: The analyses used data from 1113 adult twins in 4 provinces (Shandong, Zhejiang, Jiangsu and Sichuan) from Chinese National Twin Registry (CNTR) which collected detailed information. Those with 0 or 1 metabolic syndrome (MetS) components excluding waist circumference were considered metabolically healthy, and those with waist circumference≥90 cm in men and ≥85 cm in women as obese. All participants were categorized into four phenotypes: metabolically healthy non-obesity (MHNO), metabolically healthy obesity (MHO), metabolically unhealthy non- obesity (MUNO), metabolically unhealthy obesity (MUO). High sensitivity C reactive protein (hsCRP) was measured to assess underlying inflammation and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated as surrogate measure of insulin resistance. Results: In observational analyses of 1113 individuals (mean [SD] age, 46.6 [12.9] years; 463 obese [41.6%]). 20.3% obese twins were metabolic healthy. Serum HOMA-IR level was higher in MUNO (β=0.42, 95% CI: 0.21–0.64), MHO (β=0.68, 95% CI: 0.36–1.00) and MUO (β=0.69, 95% CI: 0.46–0.91) twins, compared with their MHNO counterparts. The chronic inflammation level, evaluated by hsCRP was similar between MHO and MUO, which differed significantly to metabolic healthy non-obesity (MHNO). Within twin-pair analysis indicated there might exist common genetic influence between HOMA-IR and MHO/MUO phenotype.Conclusions: Among Chinese adult twins, metabolic status were independently associated with higher IR while development of chronic inflammation might closely relate to central obesity. It is necessary for the different risk assessment based on metabolic status in obese population.

Published: December 2020

Abstract
Background

For women age 75 and older, there is insufficient evidence to recommend routine breast cancer screening, as the benefits may not outweigh harms. The objective of this study was to identify variables that clinicians consider influential when making screening mammography recommendations for these women and to assess the acceptability and feasibility of a patient print intervention designed to support patient decision-making and patient-clinician communication about stopping mammography.
Methods

Primary care clinicians who were part of a practice-based research network and patients aged 74–85 from this network completed surveys online and by phone, respectively.
Results

Twenty-two clinicians (18% response rate) completed the survey. The mean age at which clinicians reported that they would stop recommending screening mammography was 77.14 years. Clinicians were most likely to cite patient comorbidity [86.4%], functional status [77.3%], and cancer family history [63.6%], as well as U.S. Preventive Services Task Force (USPSTF) guidelines [81.8%] and new research regarding screening mammography [77.3%] as factors influencing their recommendations. Fourteen patients (70% enrollment rate) completed baseline surveys and received personalized booklets. Eleven (79% retention) completed follow-up surveys, reporting high intervention acceptability. Decreases in perceived breast cancer risk were significant for lifetime perceived risk (M = 26.91 vs. 4.18, p = < 0.01). Cancer worry decreased slightly (M = 1.27 vs. 1.09, p = 0.77).
Conclusions

An intervention that addresses a patients’ cancer risk and comorbidities that aligns with USPSTF guidelines appears feasible and acceptable to patients and aligns with clinicians’ values.
