Objective To study the pathological response characteristics of channel points in patients with bronchial asthma（BA）and the temperature changes of channel points in patients with different patterns.Methods Totally 81BA patients were classified into the cold pattern group and heat pattern group

with 45and 36in each.Forty healthy persons were chosen as the control group.ATIM-M301medical infrared thermal imager was used to collect the infrared thermal images.The temperature values of Zhongfu（LU1）

Chize（LU5）

Kongzui（LU6）and Lieque（LU7）in Lung Channel

Tianshu（ST25）

Quchi（LI11）

Pianli（LI3）and Hegu（LI4）in Large Intestine Channel and Yintang（EX-HN3）in Du Channel were recorded.The skin temperature of the same point on the left and right side was compared and analyzed.Results There was no significant difference between the skin temperature of the same point on the left and right side in the control group（P>0.05）.There was significant differences between the skin temperature of Zhongfu

Chize

Kongzui

Lieque

Quchi

Pianli and Hegu on the left and right side in the cold pattern group（P<0.01）.There was significant differences between the skin temperature of Zhongfu

Chize

Kongzui

Lieque

Quchi and Hegu on the left and right side in the heat pattern group（P<0.05or P<0.01）.Comparing with the control group

the average temperatures of Kongzui and Hegu were significantly lower but the average temperatures of Chize and Quchi were significantly higher in the cold pattern group（P<0.05or P<0.01）.Comparing with the control group

the average temperatures of Zhongfu

Chize

Kongzui

Lieque

Tianshu

Quchi

Pianli and Hegu were significantly higher in the heat pattern group（P<0.05or P<0.01）.Conclusion Most points in Lung Channel and Large Intestine Channel of BA patients show imbalance on the left and right side.The skin temperature values of lung-large intestine related channel points in BA patients with heat pattern are obviously higher than those in the healthy persons.
