Objective To examine the related temperature sense score in Chinese medicine body constitution scale and characteristics of acupoint biological signal in people with different Chinese medicine body constitution and to explore the correlation between them. Methods Thirty-two cases with typical Yang deficiency constitution conversion score

28 cases with Yin deficiency constitution conversion score

and 19 cases with Yin-Yang harmony constitution conversion score were screened out from 79 subjects by using Chinese medicine constitution classification and decision scale. Biological signal values of body surface of bilateral twelve yuan-primary points and eight confluence points of subjects in each group were detected with electronic system state measuring instrument. Correlation analysis was made on total scores of related temperature sense in the Chinese medicine constitution scale and the biological signal values of twelve yuan-primary points and eight confluence points. Results In 79 subjects

total scores of related temperature sense in the Chinese medicine constitution scale were negatively related to the biological signal value of right Shenmen（ HT7）（ P < 0. 05）. In Yang deficiency subjects group

total scores of related temperature sense in the Chinese medicine constitution scale were positively related to the biological signal value of left Zulinqi（ GB41）（ P < 0. 05）. In Yin deficiency subjects group

total scores of related temperature sense in the Chinese medicine constitution scale were positively related to the biological signal values of left Lieque（ LU7）

Waiguan（ SJ5）

and Gongsun（ SP4）

and right Chongyang（ ST42） and Lieque（ P < 0. 05）; and the scores were negatively related to the biological signal value of right Taiyuan（ LU9）. In Yin-Yang harmony subjects group

total scores of related temperature sense in the Chinese medicine constitution scale were positively related to the biological signal value of left Daling（ PC7）

Shenmen

Wangu（ SI4） and Gongsun（ P < 0. 05）; and the scores were negatively related to the biological signal value of left Neiguan（ PC6） and bilateral Lieque and Waiguan（ P < 0. 05）. Conclusion The biological signal value detection of yuan-primary points and eight confluence points might provide reference for constitution differentiation. There are certain correlation between the biological signal values of twelve yuan-primary points and eight confluence points in people with Yang deficiency constitution

Yin deficiency constitution and Yin-Yang harmony constitution and the total score of related temperature sense in the Chinese medicine constitution scale.
