Journal of Guangzhou University of Traditional Chinese Medicine 2015;(4):699-704
Objective To observe the curative effect of acupuncture on insulin receptor substrate 1 ( IRS-1) , IRS-2 and glucose transporter 4 (GLUT4) in skeletal muscle of experimental rats with insulin resistance (IR) . Methods Thirty-two rats were randomly divided into normal group, model group, acupuncture normal group and acupuncture model group. The fasting plasma glucose ( FPG) level was detected with glucose oxidase method, fasting insulin and C-peptide ( C-P) were examined with enzyme linked immunosorbent assay ( ELISA) , insulin sensitivity index ( ISI) was calculated, and IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of skeletal muscle were observed by real-time PCR-based fluorescent assay in each group. Results Compared to the normal group, the FPG, FINS, C-P levels were increased dramatically (P<0.01), ISI, IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of the model group declined remarkably ( P<0.01). Compared to the model group, the FPG, FINS, C-P levels declined evidently ( P<0.05 or P<0.01) , and ISI, IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA of the acupuncture model group were increased dramatically ( P<0.01). Conclusion The curative mechanism of acupuncture for insulin resistance is probably related to the increase of IRS-1 mRNA, IRS-2 mRNA and GLUT4 mRNA expression in skeletal muscle which contributes to the improvement of PI3K signal pathway.

Objective To investigate characteristics of anti-Müllerian hormone (AMH) secretion and mechanism of aberrant folliculogenesis by the ratio of luteinizing hormone (LH)/follicle-stimulating hormone(FSH) in polycystic ovarian syndrome (PCOS) patients. Methods Base on the ratio of LH/FSH,total 95 patients with PCOS were divided into two groups,including 49 cases in higher ratio group (LH/FSH≥2) and 46 cases in normal ratio group (LH/FSH < 2) matched with 62 infertile cases with tubal factor and regular menstruation as control group. Body mass index (BMI) were calculated in all objectives. The serum AMH were detected by enzyme linked immunosorbent assay(ELISA). Ovarian sexual hormones,fasting blood glucose, insulin and lipid were measured by chemiluminescence method. The correlation between AMH and metabolic index was analyzed by multilinear regression. Results (1) AMH: the serum level of AMH were (7.2±4. 3) μg/L in higher LH/FSH group, (5. 2±3. 8) μg/L in normal LH/FSH group and (3.7 ±2. 2) μg/L in control group, which all reached significant difference among those 3 groups(P < 0. 01). (2) The correlation between AMH and biological metabolic index: estradiol (E2) was negatively correlated with serum level of AMH in higher LH/FSH ratio group (r = -0. 318). The serum level of AMH were positively correlated with BMI, fasting glucose, homeostasis model assessment insulin resistance index (HOMA-IR) in normal LH/FSH ratio group (r = 0. 493,0. 362,0.303). After controlling affect factors, serum levels of AMH were positively correlated with LH/FSH in higher LH/FSH ratio group (r = 0. 301), but negatively correlated with E2 (r = -0. 429). However, in normal LH/FSH group, serum level of AMH was only positively correlated with BMI (r = 0. 428). Conclusion The PCOS patients with higher LH/FSH ratio are primarily caused by hypothalamic-pituitary dysfunction, while the PCOS patients with normal LH/FSH ratio are mainly caused by metabolic disorders.

This study aims to compare the urate-lowering response rate of febuxostat and allopurinol in gout patient using a model-based meta-analysis. The literature search identified 22 clinical trials of gout with a total of 43 unique treatment arms that met our inclusion criteria, and a total of 6 365 gout patients were included in the study. The response rates of allopuriol and febuxostat were characterized by Tmax model and Emax model respectively, and the effect of baseline serum uric acid (sUA) and patient type on the drug effect was tested. The results showed that allopurinol can reach an average maximum response rate of 50.8% while febuxostat can reach a 100% response rate within a very short time, and the ED50 was 34.3 mg. Covariate analysis revealed that baseline sUA has a negative effect on response rate of allopurinol, and a positive effect on the predicted ED50 of febuxostat. For patients who had shown inadequate response to prior allopurinol treatment, the average response rate was about half that of the allopurinol responder patients.
