摘要
目的:比较常态下督脉经线上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。方法:应用激光多谱勒血流仪对53名健康成年志愿者进行观察。测试皮肤的微循环血流灌注量时,将型号为412的测试探头直接固定于被测试部位的皮肤,保持无压力接触;测试深部组织的微循环血流灌注量时,将型号为418-1的测试探头固定在测试部位,将一次性静脉留置针插至所要测试的深度,导入光纤,同时尽量减少直射光的干扰。结果:(1)督脉线上的命门、脊中、至阳、身柱4个穴位和第12胸椎水平1个非穴位的皮肤微循环血流灌注量均要比其两侧旁开1 cm的非经对照部位高(P<0.01)。(2)督脉线上的命门、脊中、至阳、身柱4个穴位和第12胸椎水平1个非穴位的深部1、1.5、2 cm处微循环血流灌注量均要比其左右两侧旁开1 cm非经对照部位高(P<0.05)。(3)对督脉命门穴的观察发现,在深度达2.5 cm处,经穴与非经对照点微循环血流灌注量差异无统计学意义(P>0.05)。结论:沿督脉循行线的皮肤和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,深度在皮表至皮下2 cm之间。说明皮肤表面的微循环血流是形成循经红外辐射轨迹(IRRTM)的直接热源,而深部组织中的血流则是形成IRRTM的主要热源。
Objective To observe the difference of the microcirculation blood perfusion volume between the Governor Vessel （GV） running course and its bilateral control points in healthy volunteers. Methods A total of 53 healthy volunteers were recruited in the present study. Cutaneous and muscular microvascular blood perfusion units （BPU） of Mingmen （GV 4）, Jizhong （GV 6）, Zhiyang （GV 9）, Shenzhu （GV 12） and non-acupoint （at the 12^th thoracic vertebra level） of GV and their bilateral non- meridian points （ 1 cm lateral to the above mentioned GV-acupoints and non-acupoint on both sides） were measured by using a Laser Doppler Flowmetry （PeriFlux 5000）. Results 1） In comparison with bilateral control points, the cutaneous microvascular BPU values of Mingmen （GV 4）, Jizhong （GV 6）, Zhiyang （GV 9）, Shenzhu （GV 12） and non-acupoint of GV Meridian were significantly higher （P〈0.01）. 2） Compared with bilateral control points, BPU values of GV4, GV6, GV9,GV12 and non-acupoint of GV Meridian 1 cm, 1.5 cm and 2 cm beneath the skin were significantly higher （P〈0.05）. No significant differences were found between the bilateral corresponding control points of GV4, GV6, GV9, GV12 and non-acupoint of GV in cutaneous BPU values, and between bilateral control points and GV4 in BPU values of deep （2.5 cm beneath the skin） tissues （P〉0.05）. Conclusion Blood flow perfusion volumes in the skin and deeper tissues along GV are significantly higher than those of their bilateral corresponding control points, indicating that cutaneous microvascular blood flow and shallower muscular blood flow may be the heat source for forming infrared radiation trace along meridian （IRRTM） in our past studies.
