There is currently no consensus on the definition and diagnostic criteria of hyperandrogenism in PCOS. The aim of this study was to investigate the complex symptoms of hyperandrogenic disorders and the correlations between metabolism and hyperandrogenism in patients with PCOS from an outpatient reproductive medicine clinic in China. We conducted a case control study of 125 PCOS patients and 130 controls to evaluate differences in body mass index （BMI）, total testosterone （TT）, modified Ferriman-Gallwey hirsutism score, sex hormone binding globulin （SHBG）, homeostasis model assessment-estimated insulin resistance （HOMA-IR） and free androgen index （FAI） between PCOS patients and controls and subgroups of PCOS. The prevalence of acne and hirsutism did not differ significantly between the hyperandrogenic and non-hyperandrogenic subgroup. Patients with signs of hyper- androgenism had significantly higher BMI （P 〈 0.05）, but differences in TT, SHBG, FAI and waist/hip ratio were insignificant. The odds ratio of overweight was calculated for all PCOS patients. Our results suggest that PCOS patients with high BMI tend to have functional disorders of androgen excess; therefore, BMI may be a strong pre-dictor of hyperandrogenism in PCOS.展开更多

In this research, we investigated the remedial effect of slL-1-R Ⅱ administration on endometriosis in the nude mouse model. Methods： Nineteen nude model mice with endometriosis were randomly divided into three groups： group A was treated by intraperitoneal administration with only slL-1 R Ⅱ for two weeks, group B was similarly treated with only IL- 1, and group C （control） was administered saline. After 2 weeks, the size of the ectopic endometrial lesions was calculated, and the expression of vascular endothelial growth factor （VEGF） and B-cell lymphoma leukemia-2 （Bcl- 2） were detected by immunohistochemistry. The IL-8 and VEGF levels in the peritoneal fluid （PF） and serum were also measured by enzyme-linked immunosorbent assay （ELISA）. Results： The mean size of ectopic endometrial lesion did not differ between the three groups （P 〉 0.05）. Compared with the control, the expression of VEGF and Bcl-2 was significantly lower in group A, and higher in group B. In the three groups, the levels of IL-8 in the PF and serum were highest in group A, and lowest in group B. Conclusion： slL-1 R Ⅱ may suppresse hyperplasia of ectopic endometriosis, perhaps by reducing the expression of certain cytokines, such as VEGF, IL-8, and Bcl-2, which could provide a new clinical strategy for the treatment of endometriosis.展开更多
