To evaluate effects of health education on treast-feeding, studies have been conducted on 203 gravidas who were delivered of their babies in hospital. In the inteervene group, the rate of exclusively breastfeeding in the period of early sucking lates and breast-feeding according to the necessity and during the post6partum four months is higher than that of the control group, while the neonate's weight-reduction in the intervene group is lower than that of those in the control group when they leave hospital. The disparity is significant after dealt with by statistics. The study suggests that health eeeducation is on important and indispensable measure to develop breast-feeding.

Objective To investigate the effects of pioglitazone on serum adipocytokines (leptin, resistin and adiponectin) in polycystic ovary syndrome (PCOS) patients with insulin resistance (IR). Methods Thirty-five PCOS patients with IR were treated with pioglitazone 15mg/d for 12 weeks. The results of ovulation induction were observed. The changes of fasting plasma glucose (FPG), fasting serum insulin (FINS), serum levels of leptin, resistin and adiponectin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), and blood fat were examined at the baseline and after the therapy by enzyme-linked immunosorbentassay (ELISA) and radioimmunoassay (RIA). Results After 12 weeks' treatment, menstruation and rate of ovulation per cycle were improved in 35 (88.5%) PCOS patients with IR. Waist/hip ratio and F-G score were significantly decreased (P<0.05), and BMI declined with no significant difference (P>0.05). The levels of LH, T, FINS, HOMA-IR, total cholesterol, triglyceride and low density lipoprotein-cholesterol were significantly decreased (P<0.01, P<0.05) after treatment; high density lipoprotein-cholesterol level was significantly increased (P<0.01) after treatment. However, there were no significant differences in FSH and FPG (P>0.05). The levels of serum leptin and resistin were decrease than before (P<0.05), and the level of serum adiponectin was increased (P<0.05). Conclusion Pioglitazone can effectively improve clinical syndromes, insulin sensitivity, glucose and lipid metabolism of PCOS patients with IR. Adipocytokines (leptin, adiponectin and resistin) as regulators of insulin metabolism are involved in the pathogenesis of insulin resistance in PCOS. Pioglitazone treatment can decrease plasma glucose level and improve insulin sensitivity at least partly through improving the profiles of adipocytokines.

Objective To examine the expression and clinical significance of E26 transformation specific-1 in premature rupture of fetal membranes. Methods Fetal membranes from 75 women in the following categories were analyzed for Ets-1 expression: preterm and term premature rupture of fetal membranes; 70 women (control group) with term cesarean sections and without complications. Ets-1 protein was localized with the use of immunohistochemical S-P method. Results Ets-1 protein was expressed in both the nucleus and cytoplasm of trophoblast of human fetal membranes, with more obvious expression in the nucleus. Ets-1 protein's expression was up-regulated in the trophoblast of fetal membranes with premature rupture, which differed significantly from the control group (P<0.05). Ets-1 protein's expression was up-regulated in the trophoblast of fetal membranes with preterm premature rupture, which did not differ significantly from the control group (P>0.05). Conclusion Ets-1 is expressed in human fetal membranes and its expression is up-regulated with premature rupture of fetal membranes, suggesting a role for Ets-1 in extracellular matrix remodeling of the membranes. This study provides an evidence to predict premature rupture of fetal membrances.
