Serum was collected to determine the contents of PAF, inflammatory response indexes and lipid metabolism indexes.Results:Serum PAF, HMGB1, FKN, CD40L, IL-18, HCY, DKK1, LDL-C, Vaspin and Resistin levels of cerebral infarction group were greatly higher than those of control group whereas Visfatin level was greatly lower than that of control group;serum HMGB1, FKN, CD40L, IL-18, HCY, DKK1, LDL-C, Vaspin and Resistin levels of cerebral infarction group of patients with high PAF level were greatly higher than those of patients with low PAF level whereas Visfatin level was greatly lower than that of patients with low PAF level.Conclusion: The increase of PAF content in serum of patients with posterior circulation cerebral infarction is closely related to the inflammatory response activation and lipid metabolism disorder.展开更多
