The objective of the study is to assess the TNF-α levels in PCOS patients and healthy controls. A comprehensive electronic search in Medline, Embase, and the Cochrane Library database was conducted up to July 2016. Random-effects model was used to estimate the standardized mean differences (SMDs) with 95% confidence intervals (CIs). Twenty-nine studies with a total of 1960 participants (1046 PCOS patients and 914 controls) were included in this meta-analysis. The TNF-α levels in PCOS patients were significantly higher than those in controls (random-effects, SMD = 0.60, 95% CI = 0.28–0.92, P1.72(SMD = 0.967, 95% CI = 0.103–1.831, P = 0.028, I² = 93.5%) and T ratio>2.10 (SMD = 1.420, 95% CI = 0.429–2.411, P = 0.005, I² = 96.1%). By meta-regression it was suggested that ethnicity might contribute little to the heterogeneity between the included studies. Through cumulative meta-analysis and sensitivity analysis it was supposed that the higher TNF-α levels of PCOS patients compared to healthy controls was stable and reliable. This meta-analysis suggests that the circulating TNF-α levels in women with PCOS are significantly higher than those in healthy controls. It may be involved in promoting insulin resistance and androgen excess of PCOS.

We found previously that the expression of SET gene was up-regulated in polycystic ovaries. Evidences suggested that SET protein was essential for regulating both the promoter activity of CYP17A1 and the biological activity of P450c17. In this study, we explored whether SET regulated androgen production in preantral follicles.

To determine the prevalence of depression and anxiety among infertile women in Zanzibar and explore their risk factors, infertile female patients were recruited from Mnazi Mmoja Hospital in Zanzibar. The questionnaire survey was adopted. Ordinal univariate and multivariate logistic regression analyses were separately conducted to identify the risk factors associated with depression and anxiety in this sample. Among 330 infertile women, the overall prevalence of depression among patients with infertility was 40.3% and the incidence of anxiety was 66.06%. Older age (odds ratios (ORs): 1.056, 95%CI: 1.004-1.112, p = .035) and low education level (OR: 0.685, 95%CI: 0.475-0.987, p = .042) were the independent risk factors for depression. Low educational level (OR: 0.678, 95%CI: 0.482-0.954, p = .026) and primary infertility (OR: 1.546; 95%CI: 1.028-2.324, p = .036) were the risk factors for anxiety. Low educational level is a risk factor for both depression and anxiety in infertile women. Older age is a risk factor for depression and primary infertility is a risk factor for anxiety.

MiR-145-5p has been implicated in the development and progression of various disorders, and it is primarily recognized as a tumor suppressor in numerous cancers types. Its expression has been reported to decrease in the granulosa cells of patients with polycystic ovarian syndrome (PCOS). This study aimed to investigate whether miR-145-5p plays a role in granulosa cell proliferation and to shed light on the underlying pathological mechanisms of follicular development in patients with PCOS. Follicular fluid samples were collected from patients with PCOS and healthy individuals. The Cell Counting Kit-8 and bromodeoxyuridine assays were performed to assess KGN cell proliferation. The expression of miR-145-5p was significantly decreased in PCOS granulosa cells than in control cells, whereas the expression of SET was increased. Furthermore, miR-145-5p suppressed the proliferation of KGN cells. SET was identified as a direct target of miR-145-5p. Additionally, SET promoted the proliferation of KGN cells, and knockdown of SET counteracted the effect of the miR-145-5p inhibitor. Therefore, miR-145-5p regulates granulosa cell proliferation by targeting the SET in KGN cells; this process may be a potential pathological pathway that contributes to follicular developmental disorders in PCOS.

This study aimed to evaluate the effectiveness of a generative artificial intelligence based simulated patient model in improving gynecological history-tak
