Peripheral blood was collected to detect the polymorphism of Cx40 gene rs35594137 locus, and serum was collected to determine the contents of cytokines, proteases and related molecules.Results: The constituent ratio of Cx40 gene AA+AG genotype in peripheral blood of cerebral infarction group was higher than that of control group whereas the constituent ratio of GG genotype was lower than that of control group;serum IL-17, HMGB1, VCAM1, MCP-1, P-selectin, YKL-40, MMP9, TIMP1 and Caspase-3 contents as well as MMP9/TIMP1 ratio of cerebral infarction group were significantly higher than those of control group whereas ADAMTS13 and Vaspin contents were significantly lower than those of control group;serum IL-17, HMGB1, VCAM1, MCP-1, P-selectin, YKL-40, MMP9, TIMP1 and Caspase-3 contents as well as MMP9/TIMP1 ratio of cerebral infarction group of patients with CX40 gene AA+AG genotype were significantly higher than those of patients with GG genotype whereas ADAMTS13 and Vaspin contents were significantly lower than those of patients with GG genotype.Conclusion: The mutation from Cx40 gene rs35594137 allele G to A in peripheral blood of patients with cerebral infarction can promote the development of atherosclerotic plaque properties.展开更多
