ObjectiveTo investigate the effect of simvastatin on serum CRP and IL-6 in patients with acute cerebral infarction. Methods70 patients with acute cerebral infarction were randomly divided into the observation group and the control group with 35 cases in each. Conventional treatments,including enteric coated aspirin(os),low molecular weight heparin calcium(ih),iOzagrel(iv),citicoline(iv) and 6% hydroxyethyl starch(iv),were used in both groups. Additionally,10 mg simvastatin was orally used before sleeping every night in the observation group,14 days as a course. Clinical effects between two groups as well as CRP and IL-6 before and after treatment were compared.ResultsThe total effective rate in the observation group(91.4%) was higher than that in the control group(71.4%),which has a significant difference (P<0.05).Serum CRP and IL-6 levels decreased in both groups after the treatment(both P<0.05),while the observational group declined more (P<0.05). ConclusionThe combination of simvastatin with other drugs in the treatment of acute cerebral infarction can improve the clinical efficacy,for simvastatin may inhibit the generation of CRP and IL-6.
