Objective To observe the therapeutic effect of electro acupuncture at QIǖXǖ（丘墟GB40） for treating migraine and provide clinical study for Acupoints Dictionary of People＇s Republic of China. Methods Multi-center ...Objective To observe the therapeutic effect of electro acupuncture at QIǖXǖ（丘墟GB40） for treating migraine and provide clinical study for Acupoints Dictionary of People＇s Republic of China. Methods Multi-center （3 First-Class hospitals） study was adopted, and the involved 3 hospitals did clinical observation according to the requirements of the project. The methods are as follows. All cases were randomized into treatment group and control group according to their sequence. QIǖXǖ（丘墟GB40） was selected in treatment group, while Tiānshū （天枢 ST25） was selected in control group. Both groups were performed electro acupuncture, and syndromes indexes of migraine and 5-HT were observed before and after treatment. All data were analyzed by statistic software SPSS11.5. Results There was significant difference of VAS margin between two groups in each center and the combined center （u= -3. 362, P=0. 001 ）. There was significant difference of therapeutic effect of 4-week treatment between two groups in each clinical center and the combined center. The therapeutic effect of 3-month treatment between two groups in No. 1 and No. 3 hospitals, showed significant difference, the treatment group was better; while that of No. 2 hospital had no obvious difference. The therapeutic effect of 6-month treatment between two groups in each center and the combined center had significant difference, the treatment group was better. Conclusion The therapy of electro acupuncture at QIǖXǖ（丘墟GB40） is effective for migraine.展开更多
