Effect of Salvia Miltiorrhiza Polyphenolic Acid Injection on Improving Limb Use and Cognitive Impairment in Patients with Acute Stroke

AIMS: To investigate the effect of injectable salvia polyphenolic acid on the improvement of limb movement and cognitive dysfunction in acute stroke patients. MATERIALS AND METHODS: The clinical data of 90 acute stroke patients were collected for retrospective study and divided into 45 cases each in the comparison group and the observation group according to the different treatment methods; using basic treatment + salvianolic acid, the comparison group implemented conventional alteplase and butalbital treatment, and the observation group used injectable salvianolic acid treatment, to observe and compare the clinical efficacy, changes in neurological deficits, cognitive function, and motor function scores before and after treatment in the two groups. RESULTS: The NIHSS (National Institute of Health stroke scale) score, cerebral infarct volume, NSE (neuron-specific enolase), and S100β (A neurotrophic factor) levels were reduced after treatment compared with those before treatment in this group, and the NIHSS score, cerebral infarct volume, NSE, and S100β levels in the observation group were lower than those in the comparison group after treatment, and the difference was statistically significant (P < 0.05). Compared with the clinical efficacy of the comparison group and the observation group, the treatment effect of the observation group was better than that of the comparison group, and the difference was statistically significant (P < 0.05). After treatment, the cognitive function and motor function scores of both groups were significantly improved compared with those before treatment, and the degree of improvement of each score in the observation group was significantly better than that in the comparison group (P < 0.05). During the trial, two patients in the comparison group developed a generalized rash and withdrew from the experiment, and the rash subsided after anti-allergic treatment, and no significant adverse events were observed in the remaining participants. There was no statistically significant difference in liver and kidney function and cardiac enzyme test indexes between the two groups of patients at 14 days of treatment (P > 0.05). CONCLUSION: Danshen polyphenolic acid for injection has definite clinical efficacy in the treatment of acute ischemic stroke, and it can effectively improve cognitive and motor functions and promote neurological recovery in patients with high safety.
