摘要

Objective: To investigate the effects of electroacupuncture and ischemic preconditioning (IPC) on circulatory function in pigs with myocardial ischemia/reperfusion injury.Method: Eighteen pigs with myocardial ischemia/reperfusion injury were randomly allocated into three groups

6 in each. Group I was the control group

group II was the group that received IPC

and group III was that received both electroacupuncture and IPC Blood malondialdehyde (MDA)

Superoxide dismutase (SOD)

creatine phosphokinase (CPK) and its isoenzyme (CK-MB)

coronary artery flow and myocardial heat-shock protein (HSP) mRNA expression were detected for evaluation.Results: After treatment

the MDA content was decreased and SOD activities increased significantly in the acupuncture and IPC group compared with the control group (P<0.05 respectively). The levels of CPK

CK-MB at 20

60 min after reperfusion were significantly higher than those before treatment

but the levels in group III and group II were remarkably lower than those in group I. HSP70 mRNA expression was found to be increased in group II and group III at 60 min after ischemia/reperfusion compared with those in group I.Conclusion: Electroacupuncture can enhance the myocardial protection of IPC against ischemia/reperfusion injury. The. protective mechanism may be related to the improvement of antioxidation and the increased expression of HSP70 gene.
