Abstract:

AIM: To analyze the effect of metformin on patients with polycystic ovary syndrome (PCOS) and its effect on adipose tissue miR-25 level. METHODS: From March 2018 to January 2019, 76 patients with PCOS were enrolled in the department of endocrinology and gynecology in our hospital. The simple randomization method was used to divide them into two groups, 38 cases in each group. The control group was given ethinyl estradiol progesterone tablets. The observation group was given metformin on the basis of this, and the total effective rate, sex hormone binding protein (SHBG), luteinizing hormone (LH), testosterone (T), follicle stimulating hormone (FSH), and female two were compared after treatment for 6 courses. Alcohol (E2), fasting insulin (FINS), insulin resistance index (HOMA-IR), waist-to-hip ratio (WHR), body mass index (BMI), adipose tissue miR-25 mRNA level were counted. RESULTS:After treatment for 6 courses, the total effective rate was 94.74% higher than that of the control group (76.32%) (P<0.05). After 6 courses of treatment, SHBG in the observation group increased more significantly than that in the control group, while LH, T, FINS, HOMA-IR, WHR and BMI decreased more significantly than that in the control group (P<0.05). There was no significant difference in FSH and E2 between the two groups after 6 courses of treatment (P>0.05); after 6 courses of treatment, the expression of microRNA-25 in the observation group decreased more significantly than that in the control group (P<0.05).CONCLUSION:Metformin treatment of PCOS can improve the level of sex hormones and central obesity, correct endocrine abnormalities and increase insulin sensitivity. The mechanism may be related to the inhibition of miR-25 expression in adipose tissue. miR-25 targeting inhibitor provides new idea for treating PCOS.
