拔罐对健康人体背部皮肤血流量的影响

目的：观察拔罐对健康人体背部不同部位皮肤血流量的影响。方法：运用经络罐通仪控制罐压为-0．04MPa，在健康受试者大椎及双侧大杼穴拔罐10min，通过激光散斑血流监测视频系统对大椎、身柱、神道、双侧肺俞、双侧心俞拔罐前，拔罐后即刻及拔罐后第5min、第10min、第15min、第20min、第25min、第30min的血流量进行记录。结果：起罐即刻，大椎、身柱及双侧肺俞血流量较拔罐前明显升高（均P〈0．05）；与起罐即刻相比，大椎在起罐20min后各时间点，身柱在起罐后10min、15min，双侧肺俞在起罐即刻后各时间点，血流量均明显下降（均P〈0．05）。神道、双侧心俞血流量在拔罐前后的差异无统计学意义（均P〉0．05）。结论：拔罐疗法可引起皮肤血流量的变化，且距离拔罐区域越近血流变化越明显。

Effects of cupping on blood flow under skin of back in healthy human

Objective To observe the effects of cupping on blood flow under different skins of back in healthy human. Methods With meridian-cupping dredging apparatus to set cupping pressure at -0.04 MPa, cupping was applied at Dhzhui （大椎 GV 14） and bilateral Dazhu （大杼 BL 11） for 10 min in healthy subject. Blood flow monitoring video system of laser speckle was used to record blood flow of GV 14, Shenzhu （身柱 GV 12）, bilateral Feishu （肺俞 BL 13） and Xinshu （心俞 BL 15） before cupping therapy, immediate time of cupping removal and 5 min, 10 rain, 15 min, 20 min, 25 rain and 30 rain after cupping removal. Results Compared before cupping therapy, the blood flow of GV 14, GV 12 and bilateral BL 13 was obviously increased at immediate time of cupping removal （all P〈0.05）. Compared with immediate time of cupping removal, the blood flow of GV 14 at each time point after 20 rain of cupping removal, GV 12 at 10 min and 15 min after cupping removal, bilateral BL 13 at each time point after cupping removal was all obviously decreased （all P〈0.05）. The difference of blood flow of Shendao （神道 GV 11） and bilateral BL 15 before and after cupping therapy was not significantly different （all P〉0.05）. Conclusion The cupping therapy could adjust skin blood flow, which is more obvious near the cupping area.
