Objective To investigate the effects of butylphthalide injection on serum levels of inflammatory factors and oxidative stress products in patients with acute cerebral infarction. Methods A total of 120 patients with acute cerebral infarction were selected in our hospital from March 2014 to September 2016. Patients were divided into conventional treatment group (n=56) and butylphthalide group (n=64) according the therapeutic methods. The conventional treatment group was treated with improving microcirculation and resisting blood platelet aggregation, while the butylphthalide group was injected with butylphthalide (100 mL intravenous drip, twice a day) on the basis of conventional treatment. The levels of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-17, IL-23 and methane dicarboxylic aldehyde (MDA) were detected before the treatment and 7 days,14 days after the treatment. The clinical efficacy was also accessed. Results The TNF-α, IL-6, IL-17, IL-23 and MDA levels were significantly decreased 7 days and 14 days after the treatment than those before the treatment in two groups of patients (P<0.05). And the above indexes were also decreased in butylphthalide group than those of conventional treatment group (P < 0.05). No obvious adverse reactions were observed in two groups. Conclusion Butylphthalide can improve the clinical symptoms through the inhibition of inflammation and oxidative stress in patients with acute cerebral infarction.
