Rat models of primary dysmenorrhea due to cold-dampness retention were established using（0±1） ℃ ice water immersion method combined with injection of estradiol benzoate for 10 d, followed by injection of oxytocin on the 11 th day. Rats in the 3 intervention groups received moxibustion to Shenque（CV 8） and Guanyuan（CV 4）, 10 min for each acupoint, once a day. Rats in pre-moxibustion group were given mild moxibustion, beginning on the 8th day during modeling, for 3 continuous days; rats in immediate-moxibustion group were given one time mild moxibustion, immediately after injection of oxytocin on the 11 th day during modeling; rats in pre-moxibustion plus immediate-moxibustion group were given mild moxibustion, beginning on the 8th day during modeling till immediately after injection of oxytocin on the 11 th day during modeling, for 4 continuous days. The level of PGF_（2α） in the rat uterine tissues was measured by enzyme-linked immunosorbent assay（ELISA）, and the levels of PGE_2 and AVP in rat uterine tissues were measured by radioimmunoassay.Results： Compared with the blank control group, the levels of PGF_（2α） and AVP, the PGF_（2α）/PGE_2 ratio in the model group were significantly increased（P〈0.01）, and the PGE_2 level was significantly decreased（P〈0.01） in the rat uterine tissues in the model group.

Methods： A total of 90 eligible cases were randomly allocated into three groups, 30 cases in each group. Points Guanyuan（CV 4）, bilateral Zusanli（ST 36） and Sanyinjiao（SP 6） were selected for patients in all three groups, with a different treatment duration： 15 min in group A, 30 min in group B and 45 min in group C. Then the clinical efficacy in each group was evaluated by pain symptom scoring. Results： As for the pain symptom scores, there were statistically significant intra-group differences between before and after treatment in three groups（all P〈0.05）; coupled with statistically significant inter-group differences between group B and the other two groups（both P〈0.05）. As for clinical efficacy, there were statistical differences between group B and the other two groups（both P〈0.05）, indicating that 30 min of acupuncture is the optimal duration in the treatment of dysmenorrhea. Conclusion： With the same needling manipulation, 30 min of acupuncture treatment achieves a better efficacy for primary dysmenorrhea.展开更多
