Trophoblast cells serve as the foundation for placental development. We analyzed published multiomics sequencing data and found that trophoblast cells highly expressed RRS1 compared to primitive endoderm and epiblast. We used HTR-8/SVneo cells for further investigation, and Western blot and immunofluorescence staining confirmed that HTR-8/SVneo cells highly expressed RRS1. RRS1 was successfully knocked down in HTR-8/SVneo cells using siRNA. Using IncuCyte S3 live-cell analysis system based on continuous live-cell imaging and real-time data, we observed that proliferation, migration, and invasion abilities were all significantly decreased in RRS1-knockdown cells. RNA-seq revealed that knockdown of RRS1 affected the gene transcription, and upregulated pathways in extracellular matrix organization, DNA damage response, and intrinsic apoptotic signaling, downregulated pathways in embryo implantation, trophoblast cell migration, and wound healing. Differentially expressed genes were enriched in diseases related to placental development. Consistent with these findings, human chorionic villus samples collected from spontaneous abortion cases exhibited significantly reduced RRS1 expression compared to normal controls. Our results highlight the functional importance of RRS1 in human trophoblasts and suggest that its deficiency contributes to early pregnancy loss.

Objective:To evaluate the effect of value orientation brief therapy(VBT)combined with selective serotonin reuptake inhibitors(SSRIs)on clinical symptoms,rumination,decision-making ability,and cognitive func-tion in patients with mild to moderate depression.Methods:Eighty patients meeting the DSM-5 diagnostic criteria for mild to moderate depression were randomly assigned to either a medication(SSRIs)group(36 completed)or a VBT combined group(38 completed)for a 6-week intervention.Baseline and post-intervention assessments includ-ed the Hamilton Depression Scale(HAMD),Hamilton Anxious Scale(HAMA),Ruminative Response Scale-Chi-nese Version(RRS-CV),Iowa Gambling Test(IGT),number of eye fixation(NEF),responsive search score(RSS)in exploratory eye trajectory movement were used to evaluate patients'anxiety and depression symptoms,ru-minative thinking,decision-making function,and cognitive function.Results:The VBT combined group showed sig-nificantly better therapeutic effects than the medication group(P＜0.05).Compared to baseline and the medication group,the VBT combined group had significantly lower post-intervention scores in HAMD,HAMA,symptom rumi-nation,introspective reflection,compulsive meditation,and RRS-CV total scores after intervention(Ps＜0.05),and significantly higher scores in IGT net profit scores,NEF,and RSS scores(Ps＜0.05).Compared with the medica-tion group,the VBT combined group demonstrated a greater reduction in HAMD,HAMA,symptom rumination,in-trospective reflection,compulsive meditation,and RRS-CV total scores before and after intervention(Ps＜0.05),and a larger increase in IGT net profit scores,NEF,and RSS scores(Ps＜0.05).Conclusion:VBT combined with SSRIs effectively improves the symptoms of depression,anxiety,decision-making ability,rumination thinking,and cognitive function in patients with mild to moderate depression.

Objective There is a Few studies explored the association between vitamin intake and meta-bolic dysfunction-associated fatty liver disease(MAFLD),while the existing results were still contradictory.This study aimed to investigate the association between dietary vitamins and all-cause mortality as well as fibrosis risk in patients with MAFLD.Methods The data were extracted from the third National Health and Nutrition Examination Surveys 1988-1994.Dietary vitamins was assessed using a 24 h diet recall,including vitamin A,vitamin B6,vitamin B12,vitamin C,vitamin D,thiamin,riboflavin,folic acid and α-tocopherol.The non-alcoholic fatty liver disease fibrosis score(NFS)<-1.455 was considered as non-advanced fibrosis,while NFS≥-1.455 was considered as advanced fibrosis.Results A total of 3844 MAFLD participants were included in this study.The median time of follow-up was 310 months.1739 participants(45.3%)were deceased during the follow-up.The intake of thiamin,riboflavin,α-tocopherol,VB6,and VB12 were significantly higher in patients with NFS-determined non-advanced fibrosis(P<0.05).After adjusting,a significantly lower risk of fibrosis was found in patients with the highest quartile(>11.5 mg/d)of α-tocopherol intake compared to the lowest intake group(P = 0.031).Compared to the lowest quartile group,the risk of mortality was reduced by 0.34 folds in the group consuming the highest quartile amount(>130 mg/d)of VC(HRs:0.66,95%CI:0.51～0.85,P = 0.001).Conclusions More α-tocopherol intake reduced fibrosis grade in MAFLD patients.VC intake may reduce all-cause mortality in patients with MAFLD.

Hypertensive disorder of pregnancy (HDP) involves two major public health issues: mother-infant safety and prevention and controlling major chronic disease. HDP poses a serious threat to maternal and neonatal safety, and it is one of the leading causes of maternal and perinatal morbidity and mortality worldwide, as well as an important risk factor for long-term cardiovascular disease (CVD). In order to explore effective strategies to prevent and control the source of CVD and reduce its risk, we have established a cohort of HDPs in Shenzhen for the primordial prevention of CVD. The construction of the HDP cohort has already achieved preliminary progress till now. A total of 2 239 HDP women have been recruited in the HDP cohort. We have established a cohort data management platform and Biobank. The follow-up and assessment of postpartum cardiovascular metabolic risk in this cohort has also been launched. Our efforts will help explore the pathophysiological mechanism of HDP, especially the pathogenesis and precision phenotyping, prediction, and prevention of pre-eclampsia, which, therefore, may reduce the risk of adverse pregnancy outcomes, and provide a bridge to linking HDP and maternal-neonatal cardiovascular, metabolic risk to promote the cardiovascular health of mothers and their infants.

Background/Aims: Epstein-Barr virus-associated gastric cancers (EBVaGCs) have unique molecular and clinicopathological characteristics. The cyclic GMP-AMP synthase-stimulator of interferon genes (STING) pathway is recently recognized as the critical innate immunity against pathogens and tumors. STING is also a master regulator in the cancer-immunity cycle and targeting STING could synergize with existing immune-checkpoint therapies. However, the role of STING in GC, especially in EBVaGC, and its correlation with programmed death-ligand 1 (PD-L1) remain largely unclear. Methods: We collected 78 cases of EBVaGCs and 210 cases of EBV-negative GC (EBVnGC) from a total of 1,443 cases of GC analyzed by EBV-encoded small RNA in situ hybridization. We investigated STING and PD-L1 expression and their concomitant prognostic value in EBVaGCs and EBVnGCs using tissue microarray and immunohistochemistry. The effects of STING and PD-L1 expression on the overall survival of patients with EBVaGC or EBVnGC were assessed by univariate and multivariate analysis. Results: We found that both STING and PD-L1 exhibited significantly higher expression in the EBVaGCs than that in the EBVnGCs. The expression of STING was positively correlated with that of PD-L1 in EBVaGCs. Simultaneous negative expression of STING and PD-L1, and positive expression of STING were independent prognostic risk factors for EBVaGC and EBVnGC, respectively. Conclusions This is the first prognostic retrospective study of STING and PD-L1 expression and the prognosis among EBVaGC and EBVnGC. The expression and prognostic value of STING and PD-L1 are different in the two types of GCs. STING and PD-L1 are promising prognostic biomarkers and therapeutic targets for EBVaGC and EBVnGC.
