Meta-analysis showed a significant difference between the acupuncture therapy and Western medicine therapy [combined RR（random efficacy model）=1.46,95%CI（1.21,1.75）,Z=3.96,P0.0001],indicating an obvious superior effect of the acupuncture therapy;significant difference also existed between the comprehensive acupuncture therapy and acupuncture therapy alone[combined RR（fixed efficacy model）=3.35,95%CI （1.92,5.82）,Z=4.28,P0.0001],indicating that acupuncture combined with other therapies,such as points injection,scalp acupuncture,auricular acupuncture,etc.,were superior to the conventional body acupuncture therapy alone.Conclusions：The inclusion of limited clinical studies had verified the efficacy of acupuncture in the treatment of neurovascular headache.Although acupuncture or its combined therapies provides certain advantages,most clinical studies are of small sample sizes.Large sample size,randomized,controlled trials are needed in the future for more definitive results.展开更多

Method: Ninety cases were randomized into thread-embedding group, western medicine group and embedding+western medicine group (allied-therapy group), 30 cases in each one. In thread embedding group, Yingxiang (迎香 LI 20) and Feishu (肺俞 BL 13) were selected for thread embedding, once a week, totally 4 treatments were required. In western medicine group, certirizine tablet 10 mg in combination with flixonase sprayer was applied once per day, continuously for 30 days in treatment. In allied-therapy group, both of the above methods were adopted continuously for 30 days in treatment. The therapeutic effects were in statistics at the end of treatment and 1 year later. Results: At the end of treatment, in thread-embedding group, 21 cases were remarkably effective, 3 cases effective and 6 cases no effect. In western medicine group, 20 cases were remarkably effective, 3 cases effective and 7 cases no effect. In allied-therapy group, 23 cases were remarkably effective, 2 cases effective and 5 cases no effect. It was shown in statistics that there was no significant difference in therapeutic effects among three groups ( P>0.05 ). But one year after the end of treatment, it was indicated that in thread-embedding group, 3 cases were remarkably effective, 10 cases effective and 17 cases no effect; in western medicine group, 2 cases were remarkably effective, 9 cases effective and 19 cases no effect; in allied-therapy group, 7 cases were remarkably effective, 11 cases effective and 12 cases no effect. The significant difference in the therapeutic effects had not been presented in the comparison between thread-embedding group and western medicine group (P>0.05), but that had been presented between allied-therapy group with either of the groups with single therapy applied (P<0.05).

Methods： Sixty patients with prostatic hyperplasia were randomized into a treatment group and a control group, 30 in each. The treatment group was treated by electroacupuncture, and the control was prescribed with orally taken Jing Zhu Qian Lie Long Bi Tong Capsule. After treatment, the two groups were compared with each other in terms of treatment result, international prostate symptom score （I-PSS）, quality of life index （QLI）, maximum flow rate （Qmax）, and residual urine volume （RUV）. Results： The total effective rate was 96.7% in the treatment group versus 70.0% in the control, and the difference was significant （P0.05）. Both groups had marked improvement in I-PSS, QLI score, Qmax and RUV （P0.05）. Conclusion： By improving I-PSS, QLI, Qmax and RUV, electroacupuncture is an effective way for treating prostatic hyperplasia.展开更多
