OBJECTIVE:To investigate the effects of Qigong pills formula on uterine artery blood flow and endometrial recep-tivity of patients with polycystic ovary syndrome(PCOS)with infertility. METHODS:A total of 86 PCOS patients with infertility in our hospital during Jan.-Dec. 2016 were divided into control group and observation group according to random number table, with 43 cases in each group. Control group was given western medicine pituitary down-regulation therapy. Observation group was additionally given adjuvant therapy of Qigong pills formula,a dose per day,decocted with water to 400 mL,morning and night un-til artificial fertilization stopped,on the basis of control group. The uterus ultrasonic indexes and endometrial receptivity were com-pared between 2 groups before treatment and 3 months after treatment. The occurrence of ovulation,pregnancy and ADR was re-corded. RESULTS:Before treatment,there was no statistical significance in uterus ultrasonic indexes and endometrial receptivity in-dexes between 2 groups (P>0.05). Three months after treatment,endometrial thickness of 2 groups were increased significantly, while endometrial spiral arterial pulsatility indexes and resistance indexes were decreased significantly;the levels ofαvβ3 and GLUT4 were increased significantly;observation group was significantly better than control group,with statistical significance (P<0.05). The ovulation rate of observation group was 83.72％,which was significantly higher than 62.79％ of control group,with statistical significance(P<0.05). There was no statistical significance in pregnancy rate(27.91％ vs. 18.60％)between 2 groups(P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:The adjuvant therapy of Qigong pills formula help to regulate the pa-rameters of uterine artery blood flow in PCOS patients with infertility,and strengthen endometrial receptivity so as to increase ovu-lation rate.
