ABSTRACT
Objective • To investigate the risk factors for gestational diabetes mellitus (GDM) among multiparae. Methods • Women who had two consecutive pregnancies records in the International Peace Maternity and Child Health Hospital from January 2012 to January 2017 were included into this study. The case group (116 cases) and control group (464 cases) were matched at the ratio of 1:4 according to the pre-pregnancy age in index pregnancy. Clinical characteristics, biochemical parameters including oral glucose tolerance test (OGTT) and lipid profiles were took into consideration by virtue of their medical records. Multivariate Logistic regression analysis was used to compute the adjusted odds ratio (aOR) and 95%CI so as to identify the risk factors. Results • Compared with the control group, the case group was associated with greater body mass index (BMI) change between pregnancies (aOR=1.35, 95% CI=1.07-1.69), greater postprandial 1 h glucose load (aOR=1.99, 95% CI=1.55-2.55) and 2 h glucose load (aOR=2.02, 95% CI=1.51- 2.70) at OGTT in index pregnancy, and greater first-trimester fasting plasma glucose (aOR=1.96, 95% CI=1.16-3.32), total cholesterol (aOR=1.37, 95% CI=1.06-1.77) and triacylglycerol (aOR=1.53, 95% CI=1.10-2.14) in subsequent pregnancy. Conclusion • The elevated BMI change between pregnancies, the abnormal glucose and lipid profiles persisting from index to subsequent pregnancy lead to the occurrence of GDM.
ABSTRACT
Polycystic ovary syndrome (PCOS) is a gynecologic endocrine disorder with complex etiology and pathogenesis. Many women of reproductive age are influenced by this disease due to infertility. The pathogenesis of PCOS remains unclear despite increasing studies in recent years. It is generally accepted that insulin resistance, hyperandrogenism and abnormal follicle development play a pivotal role in PCOS. Gut microbiota becomes a research hotspot in the aspect of infectious, immune and metabolic diseases recently. Previous studies have found that gut microbiota could modulate the synthesis and secretion of insulin, and affect metabolism of androgen and follicle development, providing us a new idea for unravelling the pathogenesis of PCOS. Based on these researches, fecal microbiota transplantation may be a promising treatment in rectifying intestinal microecology imbalance and improving metabolism. This paper reviewed recent research advances in the roles of gut microbiota in the occurrence and development of PCOS.

ABSTRACT
This study was to improve the way for selecting ura5 mutants of Cryptoccocus neoformans Cap59 capsule-deficient strains.They were induced by Diethyl Sulfate. Ura5 mutants were screened by 5-fluoroorotic acid counter selection method. Using the new method, we obtained two ura5 mutants of Cryptoccocus neoformans Cap59 capsule-deficient strain.A easy method that was used to screen ura5 mutants of Cryptoccocus neoformans has been established.
