Effect of acupuncture the points of the pericardium channel of the Hand-Jueyin(手厥阴心包经穴) on cardium troponin in myocardial ischemia and reperfusion injury

Objective:To explore effect of acupuncture on pericardium channel of the HandJueyin points (手厥阴心包经穴) on cardium troponin(cTnT) during the process of ischemia and reperfusion injury. Methods: Fifty rats were randomly divided into five groups,normal group,ischemia and reperfusion injury group,acupuncture Neiguan point(the inner pass point,内关穴)group,Ximen point(郄门穴)group,Zhigou point(支沟穴)group.Acupuncture was given at the HandJueyin points for 20 minutes,followed by ligation of anterior descending branch of the left coronary artery and 40 minutes later,acupuncture the points for 20 minutes again, reperfusion for 60 minutes,with electrocardiogram monitoring.Then,venous blood was taken and the contents of cTnT were observed.The result on acupuncture the Zhigou point was control. Results: In the acupuncture groups,cTnT contents decreased obviously,compared with model group were significantly(both P 0 01),and compared with Zhigou point group was so (both P 0 01).Conclusion:Acupuncture the HandJueyin points can obviously control the contents of cardium troponin,reduce the injury degree during the process of ischemia and reperfusion injury.
