The serum levels of S1P, STIM1, angiogenesis molecules and inflammation molecules were detected 24 hours after PCI.Results:Serum S1P, NO, VEGF, Angptl2 and Angptl4 levels of restenosis group were significantly lower than those of non-restenosis group while STIM1, IFN-γ, IL-18, VCAM-1, P-selectin and L-selectin levels were significantly higher than those of non-restenosis group;serum NO, VEGF, Angptl2 and Angptl4 levels of restenosis group with lower STIM1 were significantly higher those of restenosis group with normal STIM1;serum IFN-γ, IL-18, VCAM-1, P-selectin and L-selectin levels of restenosis group with lower S1P were significantly higher than those of restenosis group with normal S1P.Conclusion:The decreased serum S1P and increased STIM1 after PCI have prediction value for in-stent restenosis and are closely related to the angiogenesis disorder and inflammation activation.展开更多

Serum was collected, fluorescent quantitative PCR kit was used to detect miR-148b expression, and enzyme-linked immunosorbent assay kit was used to detect the contents of myocardial injury markers and myocardial fibrosis markers.Results:Serum miR-148b expression as well as CK-MB, cTnT, H-FABP, PICP, PIIINP, CTX-I, TGF-β1 and GDF-15 levels in AMI group was significantly higher than those in control group;serum CK-MB, cTnT, H-FABP, PICP, PIIINP, CTX-I, TGF-β1 and GDF-15 levels in AMI patients with high miR-148b expression were significantly higher than those in AMI patients with low miR-148b expression.Conclusion: Highly expressed miR-148b in serum of patients with myocardial infarction can promote myocardial injury and myocardial fibrosis.展开更多
