Abstract
Background Idiopathic membranous nephropathy (IMN) is frequently coexisted with diabetes mellitus (DM). Few researches investigate clinical outcomes in IMN patients coexisting diabetes mellitus (DM), including remission rates, renal survival and complications. Concurrent DM also pose therapeutic challenges to IMN patients due to the influence of glucocorticoids and immunosuppressant on metabolic disorders. We performed this study to investigate the impact of DM on clinical outcomes in IMN and the influence of therapeutic regime on metabolic parameters in diabetic IMN patients. Methods Two hundred and six adult hospitalized patients diagnosed with biopsy-proven IMN were retrospectively studied, including 42 patients coexisted with DM. Clinical outcomes including remission rates, renal outcome and complications were compared between groups. Impact of cyclophosphamide and ciclosporin on metabolism and complications were analyzed in IMN patients coexisting DM. Results IMN patients coexisted with DM were presented with advanced age, lower level of eGFR and hemoglobin. Patients coexisted with DM experienced worse renal function deterioration and higher incidence of infection. COX regression analysis showed that DM was an independent risk factor for renal function deterioration in IMN patients. There was no significant difference in remission rates and incidence of venous thromboembolism between two groups. Further exploration on the impact of therapeutic regimens on complications and metabolism showed that cyclophosphamide and ciclosporin had no significant difference in incidence of complications including infection and venous thromboembolism, and posed comparable influences on blood glucose, uric acid and blood lipids in IMN patients coexisted with DM. Conclusion Coexisting DM was an independent risk factor for renal function deterioration in IMN patients but did not influence the remission of proteinuria. Glucocorticoids in combination with cyclophosphamide or ciclosporine had similar impact on complications and metabolic index including blood glucose, uric acid and blood lipids in IMN patients coexisted with DM.

Abstract
Background Long non-coding RNAs (lncRNAs) can play important roles in uterine and ovarian functions. However, little researches have been done on the role of lncRNAs in the adrenal gland of sheep. Herein, RNA sequencing was used to compare and analyze gene expressions in adrenal tissues between FecB ++ (WW) and FecB BB (MM) sheep in the follicular and luteal phases and key lncRNAs and genes associated with reproduction were identified. Results In MM sheep, 38 lncRNAs and 545 mRNAs were differentially expressed in the adrenal gland between the luteal and follicular phases; In WW sheep, 30 differentially expressed lncRNAs and 210 mRNAs were identified. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses indicated that differentially expressed lncRNAs and their target genes are mainly involved in the circadian rhythm, the mitogen activated protein kinase, thyroid, ovarian steroidogenesis and transforming growth factor beta signaling pathways. Key lncRNAs can regulate reproduction by modulating genes involved in these signaling pathways and biological processes. Specifically, XLOC_254761 , XLOC_357966 , 105614839 and XLOC_212877 targeting CREB1 , PER3 , SMAD1 and TGFBR2 , respectively, appear to play key regulatory roles. Conclusion These results broaden our understanding of lncRNAs in adrenal gland of sheep and provide new insights into the molecular mechanisms underlying sheep reproduction.

Authors: Li Xiaoyu , Zhou Wei , Zhan Weiwei 
Published: April 2020

Abstract
Background: To identify the sonographic features that help to differentiate medullary thyroid microcarcinomas (MTMCs) and papillary thyroid microcarcinomas (PTMCs).
Methods: A total of 46 MTMCs in 41 patients and 136 PTMCs in 104 patients that were proved by surgery and pathology, were included in the study. The age and nodule size were analyzed by independent sample t test, and the gender, multiplicity and cervical lymph node metastases were analyzed by χ 2 or Fisher’s exact tests. Univariate analysis and multivariate logistic regression analysis were performed on the sonographic features of thyroid nodules, including location, shape, boundary, margin, peripheral halo ring, echogenicity, composition, calcifications and vascularization.
Results: Compared with PTMCs, there were more MTMCs patients with cervical lymph node metastases (P=0.040). There were no significant differences in age, gender, nodule size, multiplicity, location, boundary, margin, peripheral halo ring, echogenicity and microcalcification between MTMCs and PTMCs (P > 0.05 for all). However, significant differences were found in shape (P=0.000), composition (P=0.032), macrocalcification (P=0.004) and vascularity (P=0.000) between the two groups.
Conclusions: There was some overlapping of sonographic features of MTMCs and PTMCs. However, MTMCs tended to be >50% solid composition, ovoid to round nodules with macrocalcifications and hypervascularity. Cervical lymph node metastases were more common in MTMCs patients.

Abstract
Background: Intellectual disability (ID) is a heterogeneous neurodevelopmental disorder with a complex genetic underpinning in its etiology. Chromosome microarray (CMA) is recommended as the first-tier diagnostic test for ID due to high detection rate of copy number variation (CNV). Methods: To identify an appropriate clinical detection scheme for ID in Han Chinese patients, whole genome low-coverage sequencing was performed as the first-tier diagnostic test, and medical exome sequencing (MES) as the second-tier diagnostic test for patients with negative results of CNVs. Results: A total of 19 pathogenic CNVs in 16/95(16.84%) ID patients and 10 pathogenic single-nucleotide variations (SNVs), including 6 novel mutations in 8/95(8.42%) ID patients were identified on whom no pathogenic CNVs were discovered. The detection rate of CNVs in ID with multiple congenital anomalies (MCA) subgroup was significantly higher than ID with autism spectrum disorders and other IDs subgroups. And the single-nucleotide variations showed a higher occurrence rate in the other IDs subgroup. Conclusions: There were differences in the diagnostic yields of different variation types among the three ID subgroups. Our findings provided a new perspective on appropriate clinical detection scheme in different ID subgroups based on statistically significant differences among the three ID subgroups. The application of whole genome low-coverage sequencing as the first-tier diagnostic test for ID with MCA subgroup and MES as the first-tier diagnostic test for other ID subgroup was considered as an efficient clinical detection scheme.

Abstract
Background: Accurate assessment of left ventricular (LV) systolic function is important after coronary artery bypass grafting (CABG). LV ejection fraction (LVEF) is conventionally used to evaluate LV systolic function; deformation parameters can be used to detect subtle LV systolic dysfunction. It is unclear whether an incised pericardium without sutures during CABG could affect LV morphology and function. We investigated the effect of pericardial incision on LV morphology and systolic function during CABG. Methods: Intraoperative transesophageal echocardiography was performed in 27 patients during elective CABG 5 minutes before and after pericardial incision. LV longitudinal and mid-cavity transversal diameters, sphericity index, volumes, and LVEF were measured. LV global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and twist obtained by two-dimensional speckle tracking echocardiography were measured simultaneously. Results: LV mid-cavity transversal diameter increased, while the LV sphericity index decreased ( P <0.001) immediately after pericardial incision. The GLS, GCS, and twist significantly decreased, while the GRS notably increased ( P <0.001). The LV volumes and LVEF remained unchanged. The SYNTAX score was an independent predictor of reduction of GLS by >15% immediately after pericardial incision ( P <0.001). Conclusions: Pericardial incision immediately transformed LV morphology from an ellipsoid to sphere, with decreased longitudinal and circumferential strain and twist, and increased radial strain, while LVEF remained unchanged. This should be considered when evaluating LV systolic function in patients after CABG, especially in those with a lower SYNTAX score.

Abstract
Background: Despite the demonstrated role of human Papillomavirus (HPV) in the etiology of cervical cancer and the strong evidence suggesting the importance of HPV in the development of oropharyngeal cancer, several aspects concerning the interrelationship between HPV infection in both body sites remain unknown, specifically in human immunodeficiency virus (HIV)-positive (HIV+) female patients. We aimed to assess the prevalence, distribution, and concordance of cervical and oral HPV in HIV+ women and matched HIV-negative (HIV-) controls in Brazil.
Material and methods: Cervical and endocervical samples for cytological screening and HPV detection and oral samples were collected from 115 HIV+ women using highly active antiretroviral therapy (HAART) and 139 HIV-matched controls (HIV-) in Maringá City, Brazil. Risk factors were assessed using a standardized questionnaire, and the data regarding HIV infection were obtained from the patients’ medical records. HPV detection and typing were performed using the Kit Multiplex XGEN Multi HPV Chip HS12.
Results: HIV infection was well controlled in this cohort, but women who exhibited detectable HIV load were significantly associated with HPV-positive status in overall (P = 0.03) and in cervical mucosa (P = 0.01). HIV+ women had significantly more abnormal cytological findings (P = 0.04) than HIV- women. Of the 115 HIV+ women, 48.7% were positive for cervical and/or oral HPV DNA; of the 139 HIV- women, 41% were positive for cervical and/or oral HPV (P = 0.25). Both HIV+ and HIV- women had a statistically higher prevalence of cervical HPV infection than oral infection. The concurrent HPV infection in two anatomical sites was similar in HIV+ and HIV- women, however HPV type concordance was not observed. HPV type distribution was different between the anatomical sites in both groups, and HIV+ women presented less common types, mainly in oral mucosa.
Conclusion: Our data support the importance of HPV infection in HIV+ women, even when the HIV infection is well controlled. Prospective studies are required to better understand the natural history of HPV infection in both anatomical sites, specifically in HIV+ women.

Abstract
COVID-19 has globally spread and has become a new pandemic, but there are still no effective drugs or vaccines to treat or prevent this disease. SARS-CoV-2 invades human cells through its spike proteins interacting with human ACE2 receptors, which may cause severe respiratory syndrome. One strategy to prevent the virus from entering cells is the interruption of the viral spike protein interacting with human ACE2. Facing such an urgent situation, drug repurposing is a promising strategy for rapid drug development. Here, we selected approximately 15000 molecular candidates, including FDA-approved drugs from DrugBank and natural compounds from TCMSP, to perform virtual screening for potential molecules that can target viral spike proteins, which may potentially interrupt the interaction between the human ACE2 receptor and viral spike protein. We found that digitoxin, a cardiac glycoside in DrugBank and bisindigotin, which is extracted from indigo naturalis and polygoni tinctorii foliu, in TCMSP had the highest docking scores. Note that indigo naturalis and the other herbs we found have been applied to prevent infectious diseases in traditional Chinese medicine. We also found that raltegravir, an HIV integrase inhibitor, has a relatively high binding affinity. All the docking results are presented in this article. Based on these docking results, further work will continue to identify potential molecules to prevent the spike protein from binding with the ACE2 receptor.Authors Tianzi Wei and Hao Wang contributed equally to this work.

Abstract
Background The compensatory mechanisms of the spine, pelvis, and lower limbs are essential to maintaining an upright posture. The effect of a high dislocated dysplastic hip on spinal-pelvic alignment has not been well described. The aim of this study was to investigate the sagittal spinal-pelvic alignment in patients with Crowe type IV developmental dysplasia of the hip(DDH). Methods A prospective study was conducted from July 2016 to December 2017, and 49 consecutive patients with unilateral or bilateral high dislocated dysplastic hips were enrolled. Forty-nine sex- and age-matched asymptomatic healthy adults were also recruited as a control group. The sacral slope (SS), lumbar lordosis (LL), spino-sacral angle (SSA), C7 tilt (C7T), and sagittal vertical axis (SVA[C7])were measured on lateral whole spine radiographs. The presence of low back pain and visual analogue scale (VAS) scores were recorded. Results Patients with high dislocated dysplastic hips showed significantly greater SS(47.5±7.5° vs. 40.4±6.7°, p<0.001), LL(-63.7±9.2° vs. -53.3±11.5°, P<0.001), SSA(141.8°±7.2° vs. 130.6±7.9°, p<0.001), C7T(93.9±3.6° vs. 91.1±3.7°, P<0.001), and lower SVA(C7) (-16mm[-95-45] vs. 6.4mm[-52-47], p<0.001) compared to normal controls. Patients with bilateral high dislocated dysplastic hips also exhibited larger SS, LL, SSA, and C7T and a smaller SVA(C7) than those of patients with unilateral hip dysplasia. 63.2% of the patients with high dislocated dysplastic hips reported low back pain. Conclusion Patients with Crowe type IV DDH exhibited abnormal spinal-pelvic alignment characterized by anterior pelvic tilt, lumbar hyperlordosis, and a backward-leaning trunk. Bilateral dislocated dysplastic hips had a greater impact on spinal-pelvic alignment than unilateral dislocated dysplastic hips.

Abstract
Background Although hip arthroplasty has become increasingly common, its radiological and clinical outcomes in chronic renal failure patients remain unclear. This study analyzed the outcomes of hip arthroplasty in patients with chronic renal failure undergoing dialysis. Methods Of 2,364 hips undergoing total hip arthroplasty or bipolar hemiarthroplasty between January 2003 and December 2017, data pertaining of 37 hips of patients with chronic renal failure undergoing dialysis (16 men, 21 women) were retrospectively examined. We analyzed the radiological and clinical outcomes of hip arthroplasty, as well as the occurrence of local and general complications (particularly the time of their occurrence) during follow-up and their association with dialysis duration. Results The mean patient age was 60.6 ± 13.5 years, and the mean follow-up duration was 36.6 ± 27.2 months. The mean T-value indicating bone mineral density was -2.62 ± 1.15, with osteoporosis noted in 20 cases. Except for 1 case with infection-induced change in acetabular cup tilt, all cases of total hip arthroplasty with cementless acetabular cup implant exhibited excellent radiographic outcomes. The cementless proximally coated femoral stem was used in all 25 cases of total hip arthroplasty and 7 out of 12 cases of bipolar hemiarthroplasty. Changes in the alignment of femoral stems, subsidence, osteolysis, and loosening were not observed. On clinical assessment, 33 patients received an “excellent” or “good” Harris hip score. Within 1 year postoperatively, complications developed in 18 patients, and some patients exhibited more than 1 complication. More than 1 year after surgery, general complications developed in 12 patients; however, no patient experienced local complications.Conclusions Hip arthroplasty in chronic renal failure patients on dialysis showed excellent radiological and satisfactory clinical outcomes; however, it may be associated with various postoperative complications. Therefore, meticulous preoperative treatment planning and overall postoperative management are required to reduce the risk of complications.

Abstract
Background

Statins suppress the progression of atherosclerosis by reducing low-density lipoprotein (LDL) cholesterol levels. Pemafibrate (K-877), a novel selective peroxisome proliferator-activated receptor α modulator, is expected to reduce residual risk factors including high triglycerides (TGs) and low high-density lipoprotein (HDL) cholesterol during statin treatment. However, it is not known if statin therapy with add-on pemafibrate improves the progression of atherosclerosis. The aim of this study was to assess the effect of combination therapy with pitavastatin and pemafibrate on lipid profiles and endothelial dysfunction in hypertension and hyperlipidemia model rats.

Methods

Seven-week-old male Dahl salt-sensitive (DS) rats were divided into the following five treatment groups (normal diet (ND) plus vehicle, high-salt and high-fat diet (HD) plus vehicle, HD plus pitavastatin (0.3 mg/kg), HD plus pemafibrate (K-877) (0.5 mg/kg), and HD plus combination of pitavastatin and pemafibrate) and treated for 12 weeks. At 19 weeks, endothelium-dependent relaxation of the thoracic aorta in response to acetylcholine was evaluated.

Results

After feeding for 12 weeks, systolic blood pressure and plasma levels of total cholesterol were significantly higher in the HD-vehicle group compared with the ND-vehicle group. Combination therapy with pitavastatin and pemafibrate significantly reduced systolic blood pressure, TG levels, including total, chylomicron (CM), very LDL (VLDL), HDL-TG, and cholesterol levels, including total, CM, VLDL, and LDL-cholesterol, compared with vehicle treatment. Acetylcholine caused concentration-dependent relaxation of thoracic aorta rings that were pre-contracted with phenylephrine in all rats. Relaxation rates in the HD-vehicle group were significantly lower compared with the ND-vehicle group. Relaxation rates in the HD-combination of pitavastatin and pemafibrate group significantly increased compared with the HD-vehicle group, although neither medication alone ameliorated relaxation rates significantly. Western blotting experiments showed increased phosphorylated endothelial nitric oxide synthase protein expression in aortas from rats in the HD-combination group compared with the HD-vehicle group. However, the expression levels did not respond significantly to either medication alone.

Conclusions

Combination therapy with pitavastatin and pemafibrate improved lipid profiles and endothelial dysfunction in hypertension and hyperlipidemia model rats. Pemafibrate as an add-on strategy to statins may be useful for preventing atherosclerosis progression.

Published: April 2020

Abstract
Background: The reproduction number is one of the most crucial parameters in determining disease dynamics, providing a summary measure of the transmission potential. However, estimating this value is particularly challenging owing to the characteristics of epidemic data, including non-reproducibility and incompleteness.Methods: In this study, we propose mathematical models with different population structures; each of these models can produce data on the number of cases of the influenza A(H1N1)pdm09 epidemic in South Korea. These structured models incorporating the heterogeneity of age and region are used to estimate the time-dependent effective reproduction numbers. Subsequently, the age- and region-specific reproduction numbers are also computed to analyze the differences illustrated in the incidence data.Results: The basic SIR fails to provide a reasonable estimation of the reproduction numbers. The estimated values demonstrate a large variation and remains outside of the feasible range for the influenza, regardless of the time period for data. Real-time estimation using age- and region-structured models demonstrated that the effective reproduction number rose sharply during mid-October when the ㅜumber of patients increased dramatically. The reproduction number fell below unity at the end of October and stayed lower than unity indicating that the epidemic starts decreasing, which is consistent with the incidence data.Conclusions: Numerical results reveal that the introduction of heterogeneity into the population to represent the general characteristics of dynamics is essential for the robust estimation of parameters.
