Peripheral blood was collected to detect the expression of EMMPRIN, and serum was collected to determine the contents of inflammatory cytokines and MMPs/TIMPs. Results: Peripheral blood EMMPRIN expression as well as serum ICAM1, VCAM1, IL-1β, IL-17, MMP2, MMP8 and MMP9 contents of AMI group and SAP group were significantly higher than those of control group whereas TGF-β1, sFGL-2, TIMP1 and TIMP2 contents were significantly lower than those of control group and the changes of above indexes in AMI group were more significant than those in SAP group. Serum ICAM1, VCAM1, IL-1β, IL-17, MMP2, MMP8 and MMP9 contents of AMI group of patients with high EMMPRIN expression were significantly higher than those of patients with low EMMPRIN expression whereas TGF-β1, sFGL-2, TIMP1 and TIMP2 contents were significantly lower than those of patients with low EMMPRIN expression.Conclusion:The high EMMPRIN expression in peripheral blood of patients with myocardial infarction can aggravate the inflammatory response and destroy the balance of MMPs/TIMPs.展开更多
