摘　　要：目的:比较常态下胃经与其两侧旁开的非经对照点的微循环血流灌注量有无差异以及电针对其的影响。方法:应用激光多谱勒血流仪,对21名健康成年志愿者进行观察。先将418-1型测试探头固定在所要测试部位,然后将一次性静脉留置针在胃经的上巨虚、梁丘、阴市、伏兔4个穴位和阴市与伏兔中点的非穴位点及其左右旁开1cm对照点插至1cm深度,导入光纤,尽量减少直射光的干扰,分别检测常态下及电针足三里时经脉线与非经脉线微循环血流灌注量情况。结果:①上巨虚、梁丘、阴市、伏兔4个穴位和阴市-伏兔中点的非穴位点的深部组织微循环血流灌注量都高于其两侧旁开非经对照点(P<0.01);②与电针前比,电针后胃经线下深部组织微循环血流灌注量较针前略有增高,但差异无统计学意义(P>0.05);③电针刺激可以使胃经循行线下的微循环更加均匀、顺畅。结论:沿胃经循行线下深部组织中的微循环血流灌注量均高于两侧非经对照部位,电针刺激可以使胃经循行线下的微循环更加均匀、顺畅,证实深部组织中的血流是形成循经红外辐射轨迹的主要热源,也可能是经脉参与人体机能调节活动的重要基础。Objective To observe the difference of the microcirculatory blood perfusion between acupoints and non-acupoints of the Stomach Meridian and its bilateral control points and to analyze the effect of electroacupuncture（EA） on subcutaneous microcirculatory perfusion in healthy volunteers.Methods A total of 21 healthy adult volunteers were recruited in the present study.Subcutaneous microcirculatory blood perfusion units（BPU） of Shangjuxu（ST 37）,Liangqiu（ST 34）,Yinshi（ST 33）,Futu（ST 32） and non-acupoint（the midpoint between ST 33 and ST 32） of the Stomach Meridian and their bilateral non-meridian points were measured by using Laser Doppler Flowmetry（LDF,PeriFlux 5000）.EA（0.5 Hz,duration 0.2 ms,3-4 V） was applied to Zusanli（ST 36） for 10 min.The subcutaneous microcirculatory perfusion was detected under room temperature of（28±1）℃ and humidity of about 60% after inserting a single-use syringe needle into the subcutaneous tissues（about 1 cm in depth）.Results In comparison with the bilateral control points,the subcutaneous microcirculatory BPU values of Shangjuxu（ST 37）,Liangqiu（ST 34）,Yinshi（ST 33）,Futu（ST 32） and non-acupoint regions of the Stomach Meridian were significantly higher（P〈0.01）.In comparison with pre-EA,the cutaneous microcirculatory BPU was increased mildly after EA of ST 36（P〉0.05）.Following EA for 5 to 10 min,the waveforms of LDF of the Stomach Meridian got regular and smooth.Conclusion The microcirculatory blood perfusion of acupoints and non-acupoint of the Stomach Meridian in the deeper subcutaneous tissues are significantly higher than that of their bilateral corresponding control points,suggesting that subcutaneous microvascular blood flow may be the heat source for forming infrared radiation trace along the meridian in the human body observed in our past studies.
