Objective:To evaluate the clinical curative effect of invigorating the spleen and kidney and regulating menstrual cycle treament combined with Dong's extra-point acupuncture on polycystic ovary syndrome (PCOS).Methods:According to random number table method, 70 patients with PCOS meeting inclusion criteria in the hospital were divided into western medicine group (23 cases), TCM group (23 cases) and combination group (24 cases) between January and December 2020. The western medicine was treated with ethinylestradiol and cyproterone acetate tablets, TCM group was treated with invigorating the spleen and kidney and regulating menstrual cycle treatment, and combination group was treated with invigorating the spleen and kidney and regulating menstrual cycle treatment and Dong's extra-point acupuncture. All the three groups were treated continuously for 3 menstrual cycles. Before and after treatment, levels of testosterone, estradiol, FSH and LH were detected by full-automatic immunoluminescence analyzer. The ovaries were detected by color Doppler ultrasound diagnostic apparatus. The ovarian volume, number of follicles and adverse reactions were recorded. The clinical curative effect was evaluated.Results:The differences in total response rate among western medicine group, TCM group and combination group were statistically significant [52.17% (12/23), 60.87% (14/23) vs. 87.50% (21/24), P<0.05]. After treatment, levels of testosterone [(1.02±0.12) μg/L vs. (1.23±0.25) μg/L, (1.46±0.19) μg/L, F=30.47], estradiol [(40.18±12.31) ng/L vs. (48.62±12.58) ng/L, (50.73±12.37) ng/L, F=4.78] and LH [(6.87±2.45) U/L vs. (8.28±2.29) U/L, (8.54±2.51) U/L, F=3.26] in combination group were significantly lower than those in the TCM group and western medicine group ( P<0.05). After treatment, ovarian volume [(7.05±2.34) m 3vs. (8.79±2.11) m 3, (9.12±2.18) m 3, F=5.97] in combination group was significantly lower than that in TCM group and western medicine group ( P<0.05), and number of follicles (<10 mm) (8.28±2.24 vs. 9.67±2.40, 10.15±2.64, F=3.77) was significantly lower than that of TCM group and western medicine group ( P<0.05). During treatment, difference in incidence of adverse reactions among western medicine group, Tiaozhou group and combination group was not statistically significant [21.7% (5/23), 13.0% (3/23) vs. 8.3% (2/24), P>0.05]. Conclusion:The invigorating the spleen and kidney and regulating menstrual cycle treatment combined with Dong's extra-point acupuncture can regulate levels of sex hormones, promote follicles development and ovulation, and improve ovarian morphology of PCOS patients safely.
