The effect of Salvia miltiorrhiza polyphenolic acid injection on promoting angiogenesis and improving cerebral perfusion in patients with large area cerebral infarction / 中风与神经疾病杂志

ABSTRACT

@#Objective By observing the changes of angiogenesis related factors and cerebral perfusion before and after treatment in patients with large area cerebral infarction，the formation of collateral circulation of Salvia miltiorrhiza polyphenolic acid injection and its effect on the improvement of nerve function were discussed.Methods Forty-four patients with large area cerebral infarction were selected，and all subjects were randomly divided into the salvia miltiorrhiza polyphenolic acid treatment group and the conventional treatment group （control group） according to the ratio of 1：1，with sample content of 22 patients in each group. Both groups were treated with cerebral infarction dehydration，cranial pressure reduction and brain protection，and the salvia miltiorrhiza polyphenolic acid treatment group was treated with Salvia miltiorrhiza polyphenolic acid injection on the basis of the above medication. The course of treatment in both groups was 14 days. The changes of VEGF，bFGF，Ang and quasi-continuous arterial spin labeling were observed in the two groups before and 14 days after treatment. Changes in the ratio of cerebral blood flow （CBF） to CBF in the region of interest （ROI） and contralateral image region （CBF lesions/CBFnormal），as well as changes in NIHSS score and mRS score.Results Serum levels of VEGF，bFGF and Ang in the two groups increased after treatment compared with those before treatment，and the difference was statistically significant （P<0.05）.Fourteen days after treatment，serum levels of VEGF，bFGF and Ang in the salvia miltiorrhiza polyphenolic acid treatment group were significantly higher than those in the control group，with statistically significant differences（P<0.05）.After treatment，CBF lesions/CBFnormal in the two groups were increased compared with those before treatment，and the difference was statistically significant（P<0.05）.Fourteen days after treatment，CBF lesions/CBFnormal in the salvia miltiorrhiza polyphenolic acid treatment group were significantly higher than those in the control group，with statistically significant differences（P<0.05）.The NIHSS and mRS scores of the two groups decreased after treatment compared with before treatment，with statistically significant differences（P<0.05），and the salvianolic acid treatment group decreased significantly compared with the control group （P<0.05）.Conclusion Salvia miltiorrhiza polyphenolic acid for injection can promote angiogenesis in patients with large area cerebral infarction，and can significantly improve cerebral blood flow in diseased brain tissue，improve cerebral perfusion，and then effectively improve the symptoms of neurological impairment
