Objective To investigate various sex hormones and the their relation in patients with polycystic ovary syndrome (PCOS).Methods 40 patients with PCOS were matched with 40 age matched healthy women,study group was divided into the obese group and non-obese groups based on body mass index,insulin resistance and non-insulin-resistance based on insulin sensitivity index. The level of follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), estradiol (E2), testosterone (T), androstene dione (A4), sulfal-dehydroepiandrosterone (DHEAS), sex hormone-binding globulin (SHBG), fasting glucose(FG), fasting insulin (FIN) was measured in both group. Homeostasis model assessment insulin resistance (HOMA-IR), insulin sensitivity index (ISI) and free androgen index (FAI) were caulculated. Results ①In the PCOS group,LH, LH/FSH, T, A4, FAI, FIN and Homa-IR were significantly higher compared to the control,while FSH, SHBG, ISI were significantly lower (P<0.05),PRL, FG, E2, DHEAS level did not show difference (P>0.05). ②There were significant differences in T, FAI, A4, but not in DHEAS between the PCOS group and the control one. ③There were significant differences between the hirsute group and the non-hirsute group in T, FAI, A4 (P<0.05). ④In the obese PCOS group compared to the non-obese PCOS group, T, A4, DHEAS were not significantly different, but FAI and Homa-IR were significantly higher, SHBG, ISI, LH/FSH were significantly lower. ⑤The quantity of insulin resistance in the increased T group was significantly higher compared to the common T group. ⑥In the insulin resistance group compared to the non insulin resistance group, there were not significant differences of A4、DHEAS,T and FAI was significantly higher.⑦In PCOS group,there were significant positive correlation between FAI useful parameter compared to T, A4, DHEAS for the diagnosis of PCOS. Obese PCOS women have more severe and BMI,FAI and Homa-IR;BMI and LH/FSH were significant inverse correlation. Conclusions FAI is more endocrine secretion and metabolic disturbance than non PCOS women. Hyperandrogenism and insulin resistance are consanguineous correlation.

Human DAB2 interaction protein (DAB2IP) is a novel member of Ras GTPase-activating protein family. It interacts directly with disabled-2 protein (DAB2/DOC2) which suppresses growth of cancers derived from different tissues, including mammary, prostate and ovarian cancers. DAB2IP was identified as an immediate downstream effector mediated by DAB2/DOC2. DAB2IP and DAB2/DOC2 form a unique protein complex that has a negative regulatory effect on the Ras-mediated signal pathway. It is demonstrated that DAB2IP is a tumor suppressor gene inactivated by methylation in several cancers. This article reviews the structure and biological functions of DAB2IP gene as well as its potential roles in carcinogenesis and evolution.

Objective: To explore the effect of health insurance on consumption for rural and urban households. Methods: Using empirical study with the method of quasi-social experiment. Results: Households with health insurance have more consumption than those without health insurance. The higher the coverage of family health insurance improves, the more effects medical insurance would encourage family consumption. Meanwhile, the marginal effect of health insurance on rural households ’ consumption is much bigger than that of urban households. Conclusion: Through enhancing households’ risk tolerance, health insurance reduces households’ precautionary saving motivation and impels to increase the current consumption.
