〔摘要〕 针灸镇痛机制十分复杂,是多种因素相互作用的整合过程,与微循环密切相关。血流动力学变化反映了生物组织代谢与生理功能的状态,临床上可通过测量局部组织血流动力学来反应其微循环功能状态。本文整理概括针灸镇痛改善微循环的血流成像技术,从电子显微学技术、超声多普勒成像、激光多普勒成像、激光散斑成像、近红外光成像技术方面进行分析,总结出针灸镇痛与微循环的关系以及上述检测技术的应用价值。

〔Abstract〕 The analgesic mechanism of acupuncture and moxibustion is very complex, which is an integrated process of interaction of many factors and is closely related to microcirculation. Hemodynamic changes reflect the status of metabolism and physiological function of biological tissue, and local tissue hemodynamics can be measured to reflect the status of microcirculation function in clinic. This article summarizes the empirical of acupuncture analgesia improving the flow imaging techniques of microcirculation, by expressing electron microscopy technique, ultrasonic doppler imaging, laser doppler imaging, laser speckle imaging, near-infrared spectroscopy, analying and summarizing the relationship between the analgesic effect of acupuncture and moxibustion and microcirculation, and the detection technology of application value.

微循环是微动脉、微静脉、毛细血管和组织管道内的血液循环,为组织提供营养和氧气,清除代谢废物,也在维持血流灌注及内环境稳定等方面发挥关键作用[1]。针刺镇痛机制十分复杂,是多种因素相互作用的整合过程,从外周到中枢涉及整个神经系统,也与神经化学和分子生物学有关,许多生物活性物质参与镇痛,改善了微循环[2]。灸法直接作用于局部,可以加速血流量,镇痛机制也与微循环关系密切[3]。中医学认为针灸疗法的镇痛机制离不开中医基础理论,通过穴位(包括阿是穴)、经络进行调控,达到活血化瘀、通则不痛的效果[4]。
血流动力学变化反映了生物组织代谢与生理功能的状态,临床上可通过测量局部組织血流动力学来反应其微循环功能状态[5]。目前,常用电子显微学技术、超声多普勒成像、激光多普勒成像、激光散斑成像、近红外光成像等技术检测局部微循环变化。……
