OBJECTIVE: To observe the therapeutic effect of acupuncture at Siguan points with Qinglong Baizei method on primary dysmenorrhea (PD) and to study the mechanism. METHODS:One hundred and eighty cases of PD were zandomly divided into group A, group B and group C, 60 cases in each group. Group A were treated by acupuncture at Hegu (LI 4) and Taichong (LR 3) with Qinglong Baiwei method; group B were treated by routine acupuncture with Sanyinjiao (SP 6), Ciliao (BL 32) selected as main points; and group C were treated by oral administration of Yueyueshu Decoction. After treatment of 3 months, the therapeutic effects were analyzed, and changes of hemorrheological indexes and prostaglandin level were observed. RESULTS: The cured rate and the total effective rate were 75.0% and 100.0% in group A, 60.0% and 95.0% in group B, and 25.0% and 90.0% in group C, respec tively, group A and B being significantly better than group C (P < 0.01). And the analgesic effects within 30 min of treatment in both group A and group B were significantly better than that in group C (P < 0.01), and that in group A was significantly better than that in group B (P < 0.01). CONCLUSION:Acupuncture at Siguan points with Qinglong Baiwei method has a significant therapeutic effect on primary dysmenorrhea. The possible mechanism is to relieve pain by improving blood circulation and inhibiting production of prostaglandin.
