Objective@#To systematically evaluate the detection rate of prenatal depression in Chinese women, so as to provide the reference for mental health care during pregnancy among women.@*Methods@#Publications pertaining to the detection rate of prenatal depression in Chinese women were retrieved from international and national databases from inception to July 30, 2023, including CNKI, Wanfang Data, VIP, PubMed and other databases. The Stata 17.0 software was used for meta analysis, sensitivity analysis was performed using the leave-one-out method, and the publication bias was evaluated using funnel plot and Egger's test.@*Results@#A total of 5 687 publications were retrieved, and 60 studies were finally included, with 58 in Chinese and 2 in English, 51 of medium quality and 9 of high quality, and 114 168 participants. The results of meta-analysis showed that the overall detection rate of prenatal depression in Chinese women was 23.7% (95%CI: 20.0%-27.5%). The detection rates of prenatal depression in the first, second and third trimesters were 22.1% (95%CI: 15.5%-28.6%), 16.3% (95%CI: 12.0%-20.6%) and 19.9% (95%CI: 16.0%-23.7%), in Eastern and Midwestern China were 19.7% and 27.5%, and in women with an education level of junior high school or below and high school or above were 27.2% and 17.9%, respectively, with statistically significant differences (all P<0.05). Sensitivity analysis showed that the study results were stable. There were publication bias in the results of overall detection rate of prenatal depression, and detection rates in the second and third trimester.@*Conclusions@#The overall detection rate of prenatal depression in Chinese women ranges from 20.0% to 27.5%. There are differences in the detection rate of prenatal depression in different pregnancies, with the highest detection rate in the first trimester.

Background: Long noncoding RNAs (lncRNAs) have been shown to have a fundamental role in cancer initiation and development. LncRNA microvascular invasion in hepatocellular carcinoma (MVIH) has been identified as a potential prognostic marker in several cancers; however, its role in gastric cancer (GC) has not been elucidated. Materials and Methods: A total of 152 tissue samples from patients underwent GC surgical resection in Linyi People's Hospital between 2007 and 2010 were collected. Quantitative real-time polymerase chain reaction was conducted to examine the expression level of lncRNA MVIH. The selection of clinically important cut-off scores for MVIH expression was based on receiver operating characteristic curve analysis. Then, the association between MVIH and GC clinicopathological parameters was analyzed. Moreover, univariate and multivariate Cox regression analysis were performed to reveal the relationship between MVIH and GC prognosis. Results: GC tissues exhibited a higher lncRNA MVIH expression level than paired nontumoros tissues. High MVIH level was revealed to be associated with the T stage, tumor-node-metastasis (TNM) stage and lymphatic metastasis of GC. Specially, patients with high MVIH expression level showed significantly shorter overall survival rate and progression-free survival rate. Moreover, invasion depth, distant metastasis, TNM stage, and MVIH expression were identified as risk factors of GC poor prognosis on univariate Cox regression analyses. By further analyzing these factors with multivariate logistic regression, high MVIH, and distant metastasis were discovered to be independent risk factors of GC prognosis. Conclusions: High MVIH is an independent risk factor of GC prognosis. LncRNA MVIH may serve as a potential therapeutic target and a prognostic marker of GC patients

The tumor suppressive role of oridonin, an active compound extracted from Rabdosia rubescens, has been proven in several gastric cancer (GC) cell lines. The present study aimed to evaluate the effect of oridonin on another GC cell line, SNU-216, and explore the potential mechanisms. The viable cell numbers, cell migration, survival fraction, and cell viability were, respectively, evaluated by trypan blue exclusion assay, wound healing assay, clonogenic assay, and CCK-8 assay. Cell apoptosis was determined by flow cytometry assay and western blot. The expression of p53 was inhibited by transient transfection, and the efficiency was verified by western blot. qRT-PCR was performed to measure the mRNA expression of p53. Western blot was used to evaluate the protein expression of apoptosis, DNA damage and p53 function related factors. We found that oridonin significantly inhibited cell proliferation, migration, and survivability, and enhanced cell apoptosis in SNU-216 cells. However, it had no influence on HEK293 cell viability. Oridonin also remarkably enhanced the anti-tumor effect of cisplatin on SNU-216 cells, as it significantly increased apoptotic cells and decreased cell viability. Moreover, the mRNA and protein expression of p53 was significantly up-regulated in oridonin-treated cells, while Mdm2 expression was down-regulated. Furthermore, oridonin enhanced p53 function and induced DNA damage. Knockdown of p53 or employing the caspase inhibitor, Boc-D-FMK, reversed the effect of oridonin on cell viability and apoptosis-related protein expression. The present study demonstrated that oridonin exhibited an anti-tumor effect on GC SNU-216 cells through regulating p53 expression and function.
