Abstract：Objective To observe the correlation between the subjective cold and objective body surface temperature,and acupoint temperature changes with Yang Qi.Methods According to the standard of Classification and Determination of Chinese Medicine Constitution,the subjects were divided into Group Yang deficiency and Group Gentleness constitution.An infrared thermal imaging system was used to collect and record 5 thermal images of the whole body,and the infrared heat value of the 61 areas.Twenty-four specific acupoints related with Yang Qi were measured by infrared thermometer to compare the difference of body surface temperature and acupoints temperature between the two groups.Results The surface temperature in Group Yang deficiency were significantly lower than Group Gentleness on the left anterior arm,right anterior arm,left posterior arm,right posterior arm,right anterior shoulder,left posterior shoulder,right posterior shoulder,left armpit,right cubital fossa,left heel,right heel and left toes (P ＜0.05).The surface temperatures on acupoints in Group Yang deficiency were significantly lower than those of Group Gentleness on the Danzhong,Zhongwan,Shenque,Dazhui,left Gaohuang,right Gaohuang and Yaoyangguan (P ＜ 0.05).Conclusion Patients with Yang deficiency have the subjective cold and low local surface temperature characteristics,and the temperature at some acupoints are relatively low,such as Danzhong,Zhong-wan,Shenque and et al.
