[Effects of resolving method of Chinese medicine on the lipid metabolism in polycystic ovary syndrome accompanied with non-alcoholic fatty liver disease].

OBJECTIVE

To observe the therapeutic effect of resolving method of Chinese medicine (CM) on the lipid metabolism in polycystic ovary syndrome (PCOS) patients accompanied with non-alcoholic fatty liver disease (NAFLD), to analyze the correlation between PCOS and NAFLD, and to study its mechanisms.

METHODS

Totally 70 female PCOS patients in the reproductive age (20 -40 years old) were recruited. Among them, 35 PCOS patients accompanied with NAFLD were recruited as Group A, and 35 PCOS patients without complicated NAFLD were recruited as Group B. At the same time, 20 healthy female volunteers were recruited as the control group. All subjects had their personal medical records after relevant questionnaire. Their clinical data including body height (BH), body weight (BW), body mass index (BMI), waist circumference (WC), hip circumference (HC), testosterone (T), prolactin (PRL), follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), leptin, fasting blood glucose (FBG), fasting insulin (FINS), 2 h postprandial blood glucose (2 h PBG), homeostatic model assessment for insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), etc. were detected. Patients in Group A were treated by the resolving method for 3 months. The follow-up was continued for 6 months after ending treatment.

RESULTS

The levels of BW, BMI, WHR, T, LH, LH/FSH, leptin, FINS, 2 h PBG, HOMA-IR, and LDL-C were significantly higher in Group B than in the control group (P < 0.05). The level of FSH was significantly lower in Group B than in the control group (P < 0.05). The levels of BW, BMI, WC, HC, waist-hip-ratio (WHR), leptin, FINS, 2 h PBG, HOMA-IR, TG, LDL-C, ALT, and AST were significantly higher in Group A than in Group B (P < 0.05). The HDL-C level was significantly lower in Group A than in Group B (P < 0.05). In Group A after treatment by resolving method of CM, the menstrual cycle was recovered in 83.87% patients (26/31 cases), reduced fatty liver degree or disappearance of fatty liver degree occurred in 32.26% patients (10/31 cases), with the total effective rate being 85.71% (24/28 cases).48.28% (14/29) patients were pregnant. The levels of BW, BMI, FBG, leptin, TG, ALT, and AST significantly decreased when compared with those before treatment (P < 0.05). The level of SHBG significantly increased (P < 0.05). There was no significant difference in the levels of HOMA-IR, FINS, T, FSH, LH, or LH/FSH between before and after treatment (P > 0. 05).

CONCLUSIONS

The metabolic disorder of glycolipid exists in PCOS patients, and more serious in PCOS patients accompanied with NAFLD. Resolving method can effectively restore the metabolic disturbance in PCOS patients accompanied with NAFLD, recover their fatty liver degrees, recover normal menstrual cycles, and elevate their pregnancy rates. Further studies are necessary on whether its mechanisms lie on lowering leptin levels and correcting lipid metabolisms to relieve patient's clinical symptoms.
