不同参数督脉走罐对亚健康人体背部局部皮肤血流量影响的初步观察

目的]通过观察不同参数督脉走罐对亚健康人体背部局部皮肤血流量影响及规律的变化,探讨走罐对机体阳气的影响。方法]对20名亚健康成年人分别进行静息空白观察,以及罐压为-0.01~-0.02 MPa,走罐时间为5 min,罐压为-0.02~-0.03 MPa,走罐时间为5 min,罐压为-0.02~-0.03 MPa,走罐时间为3 min的督脉走罐,应用激光散斑血流监测视频系统监测上述不同干预方法对亚健康人体大椎穴、身柱穴及大椎与身柱连线的中点,在走罐后即刻、5、10、15、20、25、30 min穴区局部皮肤血流量的变化。结果]走罐后皮肤局部血流量升高(P<0.05),随时间延长血流量逐渐降低。不同参数督脉走罐对局部血流量的影响差异无统计学意义(P>0.05),但压力较大或刺激时间较长时,血流量的变化反而较小。3个观察点在静息状态下血流量随时间变化差异无统计学意义(P>0.05),但相同压力刺激时大椎穴与身柱穴从走罐后15 min起,血流量存在区别,且走罐后大椎穴变化幅度大,身柱穴维持高峰时间长。结论]1)不同的走罐方法对督脉阳气的调节是不同的。2)走罐后皮肤局部血流量增加,机体阳气功能增强。3)穴位具有特异性。

Preliminary observation on local skin blood flow of back with sub-healthy human for different parameters cupping on Du meridian

Objective] By observing on local skin blood flow and its changes of back with sub-healthy human for different parameters cupping on Du meridian, to discuss the effects on Yang Qi in the human body. Methods] The 20 sub-healthy adults were separately observed skin blood flow on Da Zhui point and Shen Zhu point and the middle point between Da Zhui and Shen Zhu point after different parameters cupping on Du meridian that was control group and negative pressure about -0.01~-0.02 MPa with five minute and negative pressure about -0.02~ -0.03 Mpa with five minute and negative pressure about -0.02~-0.03 MPa with three minute when instant and 5, 10, 15, 20, 25, 30 minute by laser speckle. Results] The local skin blood flow was increasing after cupping and gradually reducing along the time(P<0.05). Local skin blood flow of sub-healthy human back for different parameters cupping on Du Meridian dis not have significance(P>0.05). But the change of blood flow was smaller when the negative pressure was bigger or the time was longer. The local skin blood flow about three observed points did not have significance along the time on control group(P>0.05). The local skin blood flow was different after cupping 15 minute between Da Zhui and Shen Zhu point. The amplitude of variation on Da Zhui point was bigger and the summit time was longer on Shen Zhu point. Conclusion] 1)The different cupping methods which adjust Yang Qi of Du Meridian are different. 2)The local blood flow increase after cupping and the function of Yang Qi in the human body are strengthened. 3)The acu-points have specificity.
