Mechanism of action of icaritin on uterine corpus endometrial carcinoma based on network pharmacology and experimental evaluation.

Background: Uterine corpus endometrial carcinoma (UCEC) belongs to a group of epithelial malignant tumors. Icaritin is the main active compound of Epimedii Folium. Icaritin has been utilized to induce UCEC cells to death.

Overexpression of lncRNA HCP5 in human umbilical cord mesenchymal stem cell-derived exosomes promoted the proliferation and inhibited the apoptosis of ovarian granulosa cells via the musashi RNA-binding protein 2/oestrogen receptor alpha 1 axis.

HCP5 has been reported to be downregulated in ovarian granulosa cells (OGCs) and to facilitate cell proliferation. Human umbilical cord mesenchymal stem cell exosome (hucMSCs-exo) treatment can prevent OGCs apoptosis in vitro. However, the functional mechanism of HCP5 and hucMSCs-exo requires further exploration.

HucMSCs-exosomes containing miR-21 promoted estrogen production in ovarian granulosa cells via LATS1-mediated phosphorylation of LOXL2 and YAP.

Background: Premature ovarian failure (POF) is one of the common disorders found in women leading to 1% female infertility. Clinical features of POF are hypoestrogenism or estrogen deficiency. With the development of regenerative medicine, human mesenchymal stem cells (hMSCs) therapy brings new prospects for POF.

Association of DENND1A Gene Polymorphisms with Polycystic Ovary Syndrome: A Meta-Analysis.

Objective: The rs2479106 and rs10818854 polymorphisms in the DENND1A gene have been reported to be extensively associated with risk of polycystic ovary syndrome (PCOS). However, the results from these studies remained inconclusive and conflicting. To detect a true association of rs2479106 and rs10818854 polymorphisms with PCOS risk, a single study may be underpowered, particularly for those studies with inadequate sample size.

Risk factors of polycystic ovarian syndrome among Li People.

Objective: To study the relevant risk factors of polycystic ovarian syndrome (PCOS) of Li People so as to provide basis for early diagnosis and treatment of PCOS.

Methods: With case-control study method, 285 cases of PCOS of Li People were as recruited case group, and 580 cases of non-PCOS of female Li People as control group. Questionnaire was adopted to collect data regarding risk factors of PCOS, then the risk factors of PCOS was searched by univariate and multivariate analysis.

[2-Bromoethylamine protects vascular endothelium by inhibiting SSAO activity in diabetic rats].

The purpose of this study was to investigate the change of aortic semicarbazide-sensitive amine oxidase (SSAO) activity in diabetic rats and examine the effect of 2-bromoethylamine (2-BEA) on SSAO activity and vascular endothelium in diabetic rats. SSAO was prepared from rat aorta. For assessment of the inhibitory effect, the enzymes were preincubated in the presence of different concentrations of 2-BEA before the addition of benzylamine in vitro.

Safety assessment of ovarian cryopreservation and transplantation in nude mice bearing human epithelial ovarian cancer.

Objective: Nude mice with orthotopic transplantation of human ovarian epithelial cancer were used to investigate screening criteria for paraneoplastic normal ovarian tissue and the security of the freezing and thawing for ovarian tissue transplantation.

Methods: Expression of CK-7, CA125, P53, survivin, MMP-2/TIMP- 2 in paraneoplastic normal ovarian tissues were detected by RT-PCR as well as immunohistochemistry. The tissues of the groups with all negative indicators of RT-PCR, all negative indicators of immunohistochemistry, negative expression of CK-7, CA125 and survivin, positive expression of CK-7, CA125 and survivin, cancer tissues and normal ovarian tissues of nude mice were used for freezing and thawing transplantation, to analyze overt and occult carcinogenesis rates after transplantation.

[Clinical value of multi-tumor markers protein biochip in the diagnosis of pulmonary carcinoma].

Objective: To assess the value of multi-tumor markers protein biochip in the diagnosis and therapy of pulmonary carcinoma.

Methods: Twelve tumor markers (CA199, NSE, CEA, CA242, Ferrtin, β-HCG, AFP, f-PSA, PSA, CA125, HGH, and CA153) were detected using protein chip in 308 patients with pulmonary carcinoma, 218 with benign lung lesions and 250 healthy subjects.

Results: The positivity rate was 72.

[Clinical and pathological analysis of 217 patients with IgA nephropathy from Hainan Province].

Objective: To study the clinical manifestation, pathological features and their correlation in patients with IgA nephropathy from Hainan Province.

Methods: The clinical and pathological data of 217 patients with IgA nephropathy diagnosed by renal biopsy were retrospectively analyzed.

Results: The incidence of IgA nephropathy was the highest in patients at the age of 30-39 years (50.
