OBJECTIVE： To explore the efficacy and safety of probucol combined with butylphthalide in the treatment of patients with acute cerebral infarction. METHODS： 172 patients with acute cerebral infarction were randomly divided into observation group and control group， 86 cases in each group. All patients received conventional treatment for acute cerebral infarction， including thrombolysis， anti-platelet aggregation， reducing intracranial pressure， nutritional support， intensive lipid-lowering within onset 4.5 h， timely treatment of the underlying diseases； based on it， control group received Probucol tablet， 0.5 g every times， bid. Observation group additionally received Butylphthalide and sodium chloride injection， 100 ml every times， bid， in 9：00 and 17：00 every day， infusion within 50-90 min. Both groups lasted for 2 weeks. Lipid metabolic indexes， the changes of serum S100β， NSE and hs-CRP levels， NIHSS score， clinical efficacy before and after treatment， and the incidence of adverse reactions in 2 groups were observed. RESULTS： Compared with before treatment， triglyceride （TG）， total cholesterol （TC） and low-density lipoprotein cholesterol （LDL-C） levels in 2 groups significantly decreased， high-density lipoprotein cholesterol level significantly increased， and TG， TC and LDL-C levels in observation group decreased more significantly， the differences were statistically significant （P＜0.05）. Serum S100β， NSE and hs-CRP levels and NIHSS scores in 2 groups significantly decreased， and NSE level NIHSS scores and in observation group decreased more significantly， the differences were statistically significant （P＜0.05）.  The total effective rate in observation group was 89.5％， significantly higher than control group （62.8％）， the difference was statistically significant （P＜0.05）. There were no obvious adverse reactions during treatment， and also no obvious liver and kidney function， blood coagulation and ECG changes. CONCLUSIONS： Probucol combined with butylphthalide can effectively improve the lipid metabolism and decrease serum NSE level in the treatment of patients with acute cerebral infarction， and plays positive role in early recovery of neurological function.
