提插补泻对健康人足三里穴皮肤微循环血流灌注量的影响

摘要

Objective To observe the influence of different acupuncture manipulations at Zusanli (ST 36) on blood perfusion of skin microcirculation in healthy volunteer subjects.Methods A total of 10 healthy volunteers were recruited in the present study.Acupuncture manipulations of lifting-thrusting reinforcing and reducing,uniform reinforcing-reducing,and simple needle insertion were applied to right Zusanli (ST 36) for 2 min.Changes of blood perfusion in the right Zusanli (ST 36) area were detected 1 min,5 min,10 min,15 min,20 min,25 min and 30 min after acupuncture stimulation,respectively by using a Pericam Perfusion Speckle Imager.The interval between two detections for different needling manipulations was 2 days at least.Results In comparison with pre-acupuncture stimulation,the blood perfusion levels of the skin microcirculation around the right Zusanli (ST 36) region were significantly increased from 1 min to 10 min following simple needle insertion,from 5 min to 30 min after uniform reinforcing-reducing manipulation,from 1 min to 30 min after reinforcing manipulation,and from 1 min to 25 min following reducing manipulation,respectively (P＜0.05,P＜0.01),and the effects of reinforcing manipulation were apparently superior to those of the reducing,uniform reinforcing-reducing manipulations and simple needle insertion in upregulating blood perfusion level (P＜0.05,P＜0.01).Conclusion Lifting-thrusting reinforcing,reducing,uniform reinforcing-reducing manipulations of acupuncture needle,and simple needle insertion at Zusanli (ST 36) can obviously increase blood perfusion level in normal volunteer subjects,and the effect of reinforcing manipulation is apparently better.%目的:观察提插补法和提插泻法对健康人足三里穴区局部皮肤微循环血流灌注量的影响.方法:对10名健康受试者分别进行提插补法、提插泻法、平补平泻手法以及针刺不行手法及不针刺干预,应用激光散斑血流监测视频系统监测上述不同手法针刺健康人体足三里穴后即刻,针后5、10、15、20、25、30 min穴区局部皮肤血流灌注量的变化.结果:针刺即可使足三里局部皮肤血流灌注量增加,其中提插补法及提插泻法更为明显,且补法组血流灌注量增加幅度明显高于泻法组.结论:针刺手法操作可明显提高健康人足三里皮肤血流灌注量,且补泻手法不同,影响存在差异.
