ABSTRACT
<p><b>OBJECTIVE</b>To investigate the mechanism of acupuncture at "Neiguan" (PC 6) and "Ximen" (PC 4) of the Pericardium Meridian in treatment of myocardial ischemia.</p><p><b>METHODS</b>Rats were randomly divided into 5 groups, sham-operation group, ischemia-reperfusion model group, Neiguan acupuncture group, Ximen acupuncture group and Zhigou acupuncture group. Electroacupuncture (EA) was given at corresponding acupoints for 20 min in the later 3 groups, followed by ligation of the left anterior descending branch of the coronary artery and 40 min later, acupuncture was given at the points for another 20 min, reperfusion for 60 min, with ECG monitoring. Then the myocardial tissue sample (below the ligation site) of the left cardiac ventricle was taken for preparation of sarcoplasmic reticulum, and determination of Ca2+-ATPase activity according to quantitative analysis of phosphorum. The relative mRNA levels were determined by Northerm Bolt analysis.</p><p><b>RESULTS</b>In the acupuncture groups, both the activities of Ca2+-ATPase and the gene expressions increased significantly as compared with the model group (all P < 0.01).</p><p><b>CONCLUSION</b>The points of the Pericardium Meridian can obviously improve the Ca2+-ATPase activity and the gene expressions, reduce the degree of myocardial ischemia and reperfusion injury, and strength myocardial functions.</p>
