Effect of acupuncture on the expressions of TNF-α and IFN-γ in patients with premature ovarian failure

Abstract

To explore the clinical effect of acupuncture and the potential effect mechanism in patients with premature ovarian failure. A total of 104 patients with premature ovarian failure were randomized into an acupuncture group and a western medication group, 52 cases in each one. In the western medication group, the conjugated estrogens tablets were prescribed for oral administration, 0.625 mg each time, once a day, consecutively for 21 days. On the 16th day of medication with conjugated estrogens tablets, the oral administration of medroxyprogesterone acetate tablets were supplemented, 10 mg each time, once a day, consecutively for 5 days, and then, these two kinds of western medication were discontinued for 1 week. A total of 3 cycles were required in treatment with 28 days as an artificial cycle. In the acupuncture group, acupuncture was applied. Two groups of acupoints were selected. The first group of acupoints were stimulated before ovulation and the acupoints were Guanyuan (CV 4), Guilai (ST 29), Taichong (LR 3), Taixi (KI 3), Xuehai (SP 10), Sanyinjiao (SP 6), Zigong (EX-CA 1), Yinlingquan (SP 9), Zusanli (ST 36), Shuidao (ST 28), Dahe (KI 12) and Tianshu (ST 25). The second group of acupoints were stimulated after ovulation and the acupoints included Ciliao (BL 32), Shiqizhui (EX-B 8), Ganshu (BL 18), Shenshu (BL 23), Geshu (BL 17) and Pishu (BL 20). The therapeutic effect was observed and compared in the patients between the two groups, as well as the expressions of interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) and the levels of serum luteinizing hormone (LH), follicule stimulating hormone (FSH) and estradiol (E2) before and after treatment. The total effective rate was 90.4% (47/52) in the acupuncture group, higher than 67.3% (35/62) in the western medication group (P<0.05). After treatment, the expressions of IFN-γ and TNF-α in the acupuncture group were obviously lower than the western medication group (P<0.05). Except for serum LH after treatment, at the end of treatment and in 30 days and 90 days after treatment, the levels of serum E2 in the acupuncture group were higher obviously than the western medication group and the levels of serum LH and FSH were lower obviously than the western medication group (all P<0.05). Acupuncture promotes the regular menstruation, effectively regulates the levels of serum LH, FSH and E2 and improves the pituitary gland and the ovary endocrine in the patients with premature ovarian failure. Such effect may be related to the the improvements in the expressions of IFN-γ and TNF-α, the inhibition of the apoptosis of ovarian granulosa cells, the recovery of ovarian function and the enhancement of reserve capacity.
