Abstract: Objective To explore the efficacy and value of Ginkgo biloba extract injection for patients with acute cerebral infarction. Methods 42 patients with acute cerebral infarction were selected from the Department of Neurology, Laiyang Central Hospital, Yantai City. The research started in March,2020 and finished in May,2021. All cases were divided into 2 groups according to the random number table(21 cases in each group). The control group was treated with additional Xingnaojing injection, and the observation group was treated with Ginkgo biloba extract injection. The therapeutic effect, brain function impairment, daily activity, cerebral infarction volume, cytokine level, nerve function factor and serum inflammatory factor were observed before and after treatment. Results Analysis of treatment efficacy: the observation group was as high as 95.24%, and the control group was only 66.67%. (P<0.05). After treatment, the observation group had milder brain function deficits, better daily activities, smaller cerebral infarction volume, and lower serum inflammatory factors and neurological function factors than those of control group. Data comparison between the two groups was catistically significant (P<0.05). Conclusion Ginkgo biloba extract injection has a significant effect on the treatment of acute cerebral infarction, which can improve the clinical efficacy and improve the prognosis of patients.
