Objective To observe the clinical efficacy ofTong Yuan(short forTong Du Tiao Shen,Yin Qi Gui Yuan, referring to unblocking the Governor Vessel, regulating mind, and guiding qi back to the origin) needling method plus Letrozol and human chorionic gonadotropin (HCG) in treating refractory sterility caused by polycystic ovary syndrome (PCOS).Method Sixty clomiphene citrate-resistant PCOS-induced sterility patients were recruited and randomized into two groups. The treatment group was intervened byTong Yuanneedling plus Letrozol and HCG, while the control group was intervened only by Letrozol and HCG, both for 3 months. Prior to and after the treatment,the levels of estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T) were detected; the endometrium, ovulation and pregnancy rates were also observed.Result After 3 menstrual cycles, the level of FSH increasedsignificantly (P<0.05), LH decreased significantly (P<0.05), LH/FSH declined significantly (P<0.05), and the level of T also dropped significantly (P<0.05) in both treatment group and control group; the level of E2also dropped significantly after the treatment in both groups (P<0.05), and the decrease in the treatment group was more significantly than that in the control group (P<0.05). The ovulation and pregnancy rates in the treatment group were significantly higher than those in the control group (P<0.05).Conclusion Tong Yuanneedling plus Letrozol and HCG can significantly down-regulate the levels of LH, E2and T, up-regulate the level of FSH, effectively improve the internal reproductive environment of refractory PCOS patients, and enhance the ovulation and pregnancy rates.

OBJECTIVETo observe the clinical efficacy and action mechanism of acupuncture for ovulatory disorder infertility of ovarian induction period with clomiphene citrate (CC).

METHODSThrough retrospective analysis, 36 patients with ovulatory disorder infertility were divided into CC group (16 cases) and acupuoture group (20 cases) by method. The patients in the CC group were treated with oral administration of CC (50 mg) for 5 days from the 5th day of menstruation; based on the treatment of CC, patients in the acupuncture group were treated with acupuncture; the group A of acupoint was mainly consisted of acupoints of the conception vessel and the three meridians and front- acupoints in abdomen; the group B of acupoint was mainly consisted of acupoints of the governor vessel and back- acupoints. The two groups of the acupoints were selected alternately, combined with the -guan points (Taichong (LR 3)、Hegu (LI 4)) and five- points. The needles were inserted with flying needling method, and the needles were retained for 30 min per treatment; acupuncture was given once every other day. All the patients were treated for 2 months, and treatment stopped if pregnancy occurred. The pregnancy rate, cycle ovulation rate, maximum diameter of follicle, endometrial thickness and adverse effects were compared between the two groups.

RESULTSThe pregnancy rate of the acupuncture group was 75.0% (15/20), which was superior to 37.5% (6/16) in the CC group (<0.05). The cycle ovulation rates of two groups were 70.4% (19/27, >0.05). The maximum diameter of follicle and the endometrium thickness in the acupuncture group were superior to those in the CC group (both <0.05). The incidence of adverse effects in the acupuncture group was 0% (0/20), which was lower than 18.8% (3/16) in the CC group (<0.05).

CONCLUSION acupuncture combined with CC could improve the quality of follicle and the receptivity of endometrium in patients with ovulatory disorder infertility, so as to improve the pregnancy rate, which could be used as a safe and effective means to cooperate with modern assisted reproductive technology.
