To compare the impacts on skin blood flow between moving cupping following the meridian running direction and that against the running direction.
JLG-2 meridian cupping drainage instru ment was used for moving cupping on the back along the Bladder Meridian running course in either single direction for 20 times. The cupping device was Bian stone cup, 44 mm in inner diameter, negative pressure from -0.03 to -0.04 MPa. PeriScan PIM II laser Doppler perfusion imager was used to observe the changes in skin blood flow on the running course of the Bladder Meridian with cup moved up and down and in the same region on the contralateral Bladder Meridian. Blood flow was measured before cupping, at the immediate time after cupping and 10 min after cupping separately. Fourteen healthy volunteers received the test. The measuring region was subdivided into a moving cupping area, an upstream area, a downstream area, a contralateral moving cupping area, a contralateral upstream area and a contralateral downstream area. The mean blood flow was calculated in each area.
Blood flow was increased significantly in each area and was more apparently increased in the moving cupping area. In comparison of the changing rate of blood flow between cupping following the meridian running direction and that against the running direction, it was only found that the changing rate in the upstream area of moving cupping against the running direction was significantly higher than that following the running direction (P < 0.05). The differences were not statistically significant in comparison among the other areas. Additionally, the changing rates of blood flow in the upstream and downstream area of the Bladder Meridian were increased significantly as compared with the contralateral Bladder Meridian.
The local effects are similar between moving cupping following the meridian running direction and that against the running direction. The abscopal effect of moving cupping against the running direction is superior to that following the running direction. It is suggested that the dual-directional moving cupping is applicable for the treatment of local disorders and the abscopal effect is better with moving cupping against the meridian running direction.
比较循经顺行走罐与逆经走罐对皮肤血流的影响。
采用JLG - 2型经络拔罐引流仪，沿膀胱经走行在背部进行单向走罐20次。拔罐器具为砭石杯，内径44 mm，负压为-0.03至-0.04 MPa。使用PeriScan PIM II激光多普勒血流灌注成像仪观察膀胱经走行部位在走罐上下移动时以及对侧膀胱经相同区域皮肤血流的变化。分别在拔罐前、拔罐即刻及拔罐后10分钟测量血流。14名健康志愿者接受测试。测量区域分为走罐区、上游区、下游区、对侧走罐区、对侧上游区和对侧下游区。计算每个区域的平均血流。
各区域血流均显著增加，走罐区增加更明显。比较循经顺行走罐与逆经走罐血流变化率，仅发现逆经走罐时走罐区上游的变化率显著高于顺经走罐（P < 0.05）。其他区域比较差异无统计学意义。此外，膀胱经上游和下游区域的血流变化率与对侧膀胱经相比显著增加。
循经顺行走罐与逆经走罐的局部效应相似。逆经走罐的远隔效应优于顺经走罐。提示双向走罐适用于局部病症治疗，逆经走罐的远隔效应更佳。
