To compare the difference of remote effects of acupuncture between metal needle and laser needle on facial blood perfusion (FBP).
Hand acupuncture and laser-needle acupuncture were randomly used on Hegu (LI4) in 20 healthy volunteers. FBP was observed by speckle contrast imager before, during, and after the acupunctures.
For hand acupuncture there were gradual increases on the nose and left and right visor areas (p<0.05 or p<0.01) during the acupuncture and on an immediate increase (p<0.01) that remained constant during the acupuncture on the forehead area but no significant increase on mouth area. During laser-needle acupuncture, on the other hand, there was a tendency of increase on the nose, left visor, and right visor areas but these were non significant.
Hand acupuncture can influence FBP in remote places connected by meridians.
比较金属针与激光针针刺对面部血流灌注（FBP）的远隔效应差异。
对20名健康志愿者随机采用手针针刺和激光针针刺合谷穴（LI4）。在针刺前、针刺期间和针刺后，用散斑对比成像仪观察面部血流灌注。
手针针刺时，鼻部、左右面颊区域血流灌注逐渐增加（p<0.05或p<0.01），前额区域在针刺期间即刻增加（p<0.01）且保持稳定，但口腔区域无显著增加。另一方面，激光针针刺时，鼻部、左面颊和右面颊区域有增加趋势，但不显著。
手针针刺可影响经络相连远隔部位的面部血流灌注。
