Samples from patients with GDM (n=50), and controls (n=50) were collected. Fasting insulin (FIN) was determined by radioimmunoassay. Fasting plasma glucose (FPG) was measured by oxidase assay. Western blot technique was used to detect the levels of PI-3K P85 subunit in adipose tissues of patients with GDM. The mRNA expression of PI-3K P85 subunit was detected by reverse transcription polymerase chain reaction (RT-PCR) method in the adipose tissue. PI-3K activity was examined by immunoprecipitation, thin-layer chromatography and gamma scintillation counting. The results were analyzed statistically. It was found that the levels of FPG, FIN and HOMA-IR in GDM group were significantly higher than those in control group (all P0.05). PI-3K activity was significantly decreased to 82.89% in GDM group as compared with control group (P<0.01) and negatively correlated with HOMA-IR (r=-0.75, P<0.01). It was concluded that PI-3K in GDM patients may be involved in the insulin signaling pathway, resulting in IR of GDM.展开更多

Methods： select 76 cases of endometrial cancer patients, divided into two groups, 40 in laparoscopic-alone group and 36 in laparoscopic-assisted group, and compare operation time, intraoperative blood loss, intraoperative complications, postoperative complications, lymph node number, anal exhaust time, indwelling catheter days and hospitalization days by group. Result： compared with laparoscopic-alone surgery, laparoscopic-assisted vaginal surgery has certain advantages in reducing intraoperative blood loss, intraoperative and postoperative complications, anal exhaust time, indwelling catheter days and hospitalization days. Discussion： laparoscopic-assisted vaginal surgery is a relatively safe, effective and good economic benefit surgical method in treatment of endometrial cancer.展开更多
