Methods： Clinical literatures related to PMS treated with acupuncture-moxibustion published from 2007 to 2016 were collected from Chinese Biomedical Literature Database（CBM）, Chongqing VIP Database（CQVIP）, China National Knowledge Infrastructure（CNKI）, and Wanfang Academic Journal Full-text Database（Wanfang）. The retrieved data underwent descriptive analysis, cluster analysis and association pattern analysis to determine the acupoints selection principle in acupuncture-moxibustion treatment of PMS. Results： The top five acupoints used in acupuncture-moxibustion treatment of PMS were Sanyinjiao（SP 6）, Shenshu（BL 23）, Guanyuan（CV 4）, Baihui（GV 20）, and Shenmen（HT 7）. The leading 4 meridians were Bladder Meridian, Conception Vessel, Spleen Meridian, and Governor Vessel. The clustering analysis showed that the 5 core acupoint groups were：（1） Sanyinjiao（SP 6）;（2） Shenshu（BL 23） and Guanyuan（CV 4）;（3） Baihui（GV 20）, Shenmen（HT 7）, Zusanli（ST 36）, Ganshu（BL 18） and Taichong（LR 3）;（4） Taixi（KI 3）, Pishu（BL 20）, Xinshu（BL 15）, Qihai（CV 6） and Neiguan（PC 6）;（5） Sishencong（EX-HN 1）, Zhongwan（CV 12）, Hegu（LI 4）, Yintang（GV 29）, Fengchi（GB 20）, Zhongji（CV 3） and Feishu（BL 13）. The three most significant acupoints were Sanyinjiao（SP 6）, Shenshu（BL 23） and Guanyuan（CV 4）. Acupoint groups based on syndrome differentiation included：（1） Hegu（LI 4）, Zhongwan（CV 12） and Sishencong（EX-HN 1）;（2） Feishu（BL 13）, Zhongji（CV 3）, Fengchi（GB 20） and Yintang（GV 29）;（3） Xinshu（BL 15）, Pishu（BL 20）, Qihai（CV 6）, Neiguan（PC 6） and Taixi（KI 3）;（4） Ganshu（BL 18）, Zusanli（ST 36）, Shenmen（HT 7）, Taichong（LR 3） and Baihui（GV 20）. The analysis of association pattern elaborated that Shenshu（BL 23） and Sanyinjiao（SP 6） won the highest support rate in the paired groups; Ganshu（BL 18）, Shenshu（BL 23） and Sanyinjiao（SP 6） had the highest support rate among the acupoint groups. Conclusion： The data mining results of acupuncture-moxibustion treatment of PMS substantially conform to the general principle in traditional acupuncture-moxibustion theories, able to reflect the acupoints selection and grouping pattern and provide references for acupuncture-moxibustion treatment of PMS.展开更多

Method： There were 47 cases with menopause syndrome, which were divided into two groups, 32 cases in the acupuncture group, treated by acupuncture with main acupoins of Shenshu （BL 23）, Zusanli （ST 36） and Sanyinjiao （SP 6）, and 15 cases in the control group, treated by orally taking the Oryzanol. The Kupperman index of the two groups was observed before and after treatment for evaluating the therapeutic effect. The changes of blood-serum E2, T, FSH, LH of the 25 cases in the acupuncture group were tested by radioimmunoassay before and after the treatment. Results： The acupuncture therapy can relieve the clinical symptoms of menopause syndrome, and its therapeutic effect was better than Oryzanol. After being treated by acupuncture therapy, the content of blood-serum E2 obviously increased, while the contents of LH and T declined, and the FSH also had a tendency to lower, but it was not statistically significant. Conclusion： The therapeutic effect of acupuncture therapy for menopause is confirmed. The acupuncture therapy can improve the function of hypophysial-gonadal axis of the patient with menopause syndrome, which may be the main mechanism of the acupuncture therapy for treating menopause syndrome.展开更多
