OBJECTIVE: Use proteomic technique to research the effects of Qishenyiqi formula in acute myocardial infarcted rats, and further explore its protein-level mechanism. METHOD: The rat hearts of sham, myocardial infarcted and Qishenyiqi formula treated groups were collected. Analyzing and comparing the differences of protein expressions in each groups with two-dimensional electrophoresis, computer-assisted image analysis and matrix-assisted laser desorption/ionization mass spectrometry. RESULT: Compared with myocardial infarcted group, there were 14 protein expressions changed in Qishenyiqi formula treated group. The result showed that 9 protein expressions were up-regulated, and 5 ones were down-regulated significantly. These proteins are associated with energy metabolism, mitochondrial function, oxidative stress, cytoskeleton and others. CONCLUSION: Myocardial protective effects of Qishenyiqi formula in myocardial infarcted procedure might be closely related to the recovery of energy supply, the reduction of oxidative stress, as well as the promotion of cell recovery.
