Abstract: ObjectiveTo explore the effect of recombinant human granulocyte colony-stimulating factor (rhG-CSF) on acute cerebral infarction.Methods74 patients with acute cerebral infarction were divided into treatment and control groups. Two groups were treated by conventional methods of acute cerebral infarction; the treatment group was treated with rhG-CSF additionally. The two groups were measured before and 3 months after treatment by China Stroke Scale (CSS), respectively. Meanwhile, the side effect of rhG-CSF was observed during treatment.ResultsCSS score was better in the treatment group than in the control group 3 months after treatment (P＜0.05). No side effect occurred in the treatment group.ConclusionrhG-CSF is safe and effective to treat acute cerebral infarction.
