Objective To explore the effect of Salvianolic Acid for Injection combined with rosuvastatin in the treatment of acute ischemic stroke and its effect on the expression of lipoprotein related phospholipase A₂ (Lp-PLA₂), oxidized low-density lipoprotein (ox-LDL), and interleukin 6 (IL-6). Methods A total of 200 patients with acute ischemic stroke admitted to Anyang People's Hospital from January 2020 to October 2022 were selected for retrospective analysis. According to different treatment schemes, the patients were divided into control group and experimental group, with 100 cases in each group. The patients in the control group received thrombolysis, conventional symptomatic treatment+rosuvastatin (10 mg each time, once a day after dinner). The patients in the experimental group were added with Salvianolic Acid for Injection on the basis of the control group, 0.13 g each time, once a day, diluted with 250 mL of 0.9% Sodium Chloride Injection, and intravenous drip. Both groups were treated continuously for 14 days. The clinical efficacy of two groups was compared, and the serum levels of Lp-PLA₂, ox-LDL, IL-6, as well as the cerebral blood flow velocity of the middle cerebral artery (MCA), anterior cerebral artery (ACA), and posterior cerebral artery (PCA) were compared before and after treatment. The occurrence of adverse reactions in both groups were observed during the treatment period. Results The total effective rate of the experimental group was 97.00%, which was significantly higher than the control group's 89.00% (P＜0.05). Before treatment, there was no significant difference in the levels of serum Lp-PLA₂, ox-LDL, IL-6, cerebral blood flow velocity of MCA, ACA, and PCA between the two groups of patients (P＞0.05). After treatment, the serum levels of Lp-PLA₂, ox-LDL, and IL-6 in both groups were significantly reduced compared to before treatment in same group (P＜0.05), and the experimental group was lower than the control group (P＜0.05). After treatment, the cerebral blood flow velocity of MCA, ACA, and PCA in both groups significantly increased compared to before treatment in same group (P＜0.05), and the experimental group was higher than the control group (P＜0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P＞0.05). Conclusion The combination of Salvianolic Acid for Injection and rosuvastatin in the treatment of acute ischemic stroke can not only improve the cerebral blood flow velocity, regulate the expression of Lp-PLA₂, ox-LDL and IL-6, but also improve the overall efficacy and safety.
