摘　　要：目的:观察正常人体委中穴区刮痧前后经脉线上皮肤微循环血流灌注量的变化,探讨穴区刮痧疗效的作用机制。方法:在10例健康人体膀胱经委中穴区刮痧,应用激光多普勒血流成像仪,观察刮痧前至刮痧后90min内,委中穴区及本经同侧经脉线上气海俞区域的皮肤微循环血流灌注量变化情况,利用LDPI图像软件处理相关数据,进行组内比较和相关性统计学分析。结果:委中穴区刮痧后即刻至90min各时间段血流灌注量与刮痧前相比均显著升高(P<0.001,P<0.01);委中穴区刮痧后15、60、90min时,本经同侧经脉线气海俞穴区皮肤血流灌注量与刮痧前相比均有不同程度升高(P<0.05)。委中穴区与气海俞穴区之间血流灌注量变化存在正相关关系(P<0.05)。结论:穴区刮痧可明显增加本经经脉线上皮肤微循环血流灌注量,改善皮肤微循环,促进沿经组织新陈代谢,是刮痧活血化瘀、疏通经络以及畅通气血运行的机制之一。Objective To observe the effect of Guasha （scraping） of Weizhong （BL 40） on the cutaneous blood perfu- sion of Qihaishu （BL 24） region of the Bladder Meridian on the back. Methods Ten healthy volunteer subjects were recuited in the present study. Weizhong （BL 40, at the politeal fossa） area was repeatedly scraped till regional flush using a cornu bubali scraping plate for 5 min after applying scraping oil to the regional skin. Then blood perfusion levels of the skin microcirculation a- round Weizhong （BL 40） and Qihaishu （BL 24） regions on the ipsilateral back were detected using a Laser Doppler flowmetry （PeriScan PIMⅡ ）. Results Following scraping Weizhong （BL 40） region, the cutaneous blood perfusion levels in the stimula- ted region were increased significantly at the time-points of 0, 15, 60 and 90 min after scraping （P〈0. 001, P〈0.01 ）, while those of Qihaishu （BL 24） area at the lumbar part also showed a remarkable increase 15, 60 and 90 min after scraping compared with the basic value （P〈0.05）. A positive correlation was found between BL 40 and BL 24 areas in the cutaneous blood perfusion levels after scraping BL 40 （P〈0.05）. Conclusion Scraping stimulation of Weizhong （BL 40） can improve the cutaneous mi- crocirculation of the stimulated BL 40 and Qihaishu （BL 24） regions in healthy volunteers, suggesting a close connection between BL 40 and the back described in Chinese medicine.
