摘　　要：目的 通过联合使用红外热像和激光多普勒血流成像技术,对电针和艾灸引起的小腿穴区皮肤温度和微循环灌注变化进行观察,了解针灸对下肢局部温度与血流灌注的效应.方法 分别对10例健康人电针和艾灸足三里穴,应用红外热像、激光多普勒血流成像技术,观察丰隆穴、下巨虚穴和皮肤高温区的温度及皮肤微循环灌注的改变,并进行温度和血流值的定量化分析.结果 电针后,小腿外侧面3个分析区域温度变化较小,升温在0.13 ～0.23℃之间,各观察时点均无统计学差异;艾灸后,所观察的3个分析区升温较高,在1.33 ～3.22℃之间,具有统计学差异（P＜0.05）,停灸后仍有一定升温.不论电针还是艾灸,施治后对所分析区域的血流灌注均有明显增加,电针组在0.14 ～0.17 PU之间,艾灸组在0.19 ～0.39 PU范围,2组各时间点与前对照比较具有统计学差异（P＜0.05）.艾灸时,所观察的小腿区域血流随温度的增加而增加,呈现相关性（P＜0.05）.结论 电针和艾灸对下肢穴区血流灌注作用十分显著,并且艾灸提高组织温度的作用比电针更强;改善组织血液循环和代谢活动是针灸主要作用机理之一.Objective To observe the changes of skin temperature and blood perfusion induced by electroacupuncture and moxibustion in acupoint zones of lower limbs,and to study the curative effect of acupuncture and moxibustion on local temperature and blood flow of lower limbs through the integrated application of infrared thermal imagining and laser Doppler.Methods The health subjects （n =10） were given electroacupuncture and moxibustion in Zusanli （ST36） respectively.The changes of temperature and microcirculation perfusion in Fenglong （ST40）,Xiajuxu （ST39） and high temperature zone of skin were observed by using infrared thermal imagining and laser Doppler,which were analyzed quantitatively.Results After electroacupuncture,the temperature of 3 zones in outer side of lower leg increased slightly （rising from 0.13℃ to 0.23℃）.The difference in the temperature collected from different time points had no statistical significance.After moxibustion,the temperature of 3 zones increased significantly （rising from 1.33℃ to 3.22℃,P ＜ 0.05）.The blood perfusion could be improved by both electroacupuncture and moxibustion in test zones,and it was 0.14 PU to 0.17 PU in electroacupuncture group and 0.19 PU to 0.39 in moxibustion group,and thaer was statistical difference between two groups at all time points （P ＜ 0.05）.During mosibustion,blood flow in the zone of lower leg increased as temperature rising showed a correlation between them （P ＜ 0.05）.Conclusion The influences of electroacupuncture and moxibustion on blood flow of lower limbs are significant,while the warming effect of moxibustion is more significant than that of electroacupuncture.One of the effective mechanisms of acupuncture and moxibustion is to improve blood circulation and metabolism in local tissue.
