艾灸对不同中医体质人体红外热像等的即刻效应

Immediate Influences of Moxibustion on Infrared Thermal Images of different constitutions

目的:研究不同体质人体红外热像、皮肤电导、血氧饱和度、心率的特点及其在艾灸后即刻效应,探讨艾灸调理体质的机制。方法:将45名在校大学生按体质分为4组,并对所有受试者的的双侧劳宫穴、神阙穴、双侧足三里及双侧涌泉穴依次进行艾灸,同时记录艾灸前后及过程中皮肤电导、血氧饱和度、心率的变化,并采集其中41人艾灸前、后的红外热像。结果:艾灸前,阳虚质眼部和大腿正面的红外热像数据有小于平和质的倾向,阴虚质有大于平和质的倾向;阳虚、阴虚、阴阳两虚三种偏颇质的神阙区域红外热像数据和心率都小于平和质;阳虚质的皮肤电导、阴虚质的血氧饱和度低于平和质,阳虚质的血氧饱和度、阴虚质的皮肤电导均高于平和质,阴阳两虚质的皮肤电导及血氧饱和度都有低于平和质的趋向,但各体质之间的以上差异均无统计学意义(P>0.05)。艾灸后,各体质受试者的某些部位的红外热像数据、皮肤电导、心率升高,血氧饱和度下降,与艾灸前比较,变化均有统计学意义(P<0.05)。结论:以上结果一方面反映了不同体质脏腑阴阳气血和功能代谢活动的差异性,另一方面也说明艾灸对体质的调理作用,跟其调节机体的温度、皮肤电导、血氧饱和度等有关。

Objective：To study the characteristic of infrared thermal images and skin conductance, SpO2 , heart rate of different constitution human body and its immediate changes after moxibustion and discuss the mechanism of adjusting constitution with moxibustion. Methods ： These physiological indexes were recorded, while moxibustion were being carried on the acupoints of bilateral Laogong, Shenque, bilateral Zusanli and bilateral Yongquan in sequence of 45 subjects who had been divided into 4 constitution groups, and infrared thermal images were acquired both before and after moxibustion. Results ： Before moxibustion, the infrared thermal images data of Yang-deficiency subjects＇ eyes and thighs were lower than normal subjects, but Yin-defieieney subjects＇ were higher than normal subjects＇ , and the infrared thermal images data of Shenque area and heart rate of abnormal constitution subjects＇ were lower than normal subjects＇ ; Yang-deficiency subjects＇ skin conductance and Yin-defieiency subjects＇ SpO2 lower than normal subjects＇ , and Yang-defieiency subjects＇ SpO2 and Yin-deficiency subjects＇ skin conductance larger than normal subjects＇ ; Yinyang-defieieney subjects＇ skin conductance and SpO2 were both lower than normal subjects＇. But the differences among the 4 constitutions were statistically insignificant （ P 〉 0. 05 ）. After moxibustion, some infrared thermal images data, heart rate and skin conductance of the 4 constitutions were increased, and the SpO2 were decreased, and the changes had statistical significance（ P 〈 0.05 ）. But the physiological indexes of some subjects changed in the opposite direction, and the proportion was different with different constitutions. Conclusion： The result above indicates the differences of yin, yang, qi and blood and the metabolic activity of different constitutions on one hand, on the other hand, it proves that maybe moxibustion adjust constitution through adjusting temperature, skin conductance, SpO2 and heart rate.
