Objective To study the relationship between serum adiponectin and insulin resistance in wo men with polycystic ovary syndrome(PCOS). Methods Forty women with PCOS and twenty five healthy women were divided into PCOS obese group [body weight index(BMI)≥25kg/m 2], PCOS non-obese group(BMI

Objective To study the expression of glucose transporter-1 (GLUT_1) and its correlation with basic fibroblast growth factor (bFGF) and proliferating cell nuclear antigen (PCNA) in epithelial ovarian neoplasm. Methods Streptavidin-peroxidase complex technique was used to examine the expression of GLUT_1, bFGF and PCNA protein in six cases of normal ovarian tissue, 20 cases of benign epithelial tumors, seven cases of borderline tumor and 44 cases of epithelial ovarian carcinoma. Results In normal ovary and benign ovarian tumor, GLUT_1 was not detected,but in borderline ovarian tumor and cancer, the positive expression ratio of GLUT_1 was 6/7 and 91%(40/44), respectively. The intensity of GLUT_1 in ovarian epithelial neoplasm was significantly higher than in borderline tumors. The staining intensity of GLUT_1 was significantly correlated with the histological grade of the tumor (r_S=0.499, P=0.001), and was positively correlated with the clinical stage, cancer invasion and lymph node metastasis. GLUT_1 staining was intense in cytoplasmic membrane, and was stronger in areas far away from blood vessels and near the necrotic center. GLUT_1 expression level did not show any association with histology type (P=0.513). bFGF positive rate in tumor was 57%(25/44). The staining intensity of GLUT_1 was significantly higher in bFGF positive group than in bFGF negative group (P
