Abstract

Background and aims Therapeutic angiogenesis is a pivotal strategy for ischemic heart disease. The aim of the present study was to determine the effect and molecular mechanism of Shexiang Baoxin pills, a widely-used traditional Chinese medicine for ischemic heart disease, on angiogenesis in a rat model of myocardial infarction (MI). Methods We used the occlusion of left anterior descending coronary artery of Sprague-Dawley rats as a model of MI. The MI rats were treated with distilled water, Shexiang Baoxin pills, or Shexiang Baoxin pills + HET0016 (a selective blocker of the biosynthesis of 20-hydroxyeicosatetraenoic acid (20-HETE) at 10 mg/kg/day), respectively. Sham-operated rats were used as controls. Results Treatment with Shexiang Baoxin pills increases the level of serum 20-HETE in MI rats, which can be suppressed by HET0016 treatment. Shexiang Baoxin pills shows cardio-protective effects on MI rats, including improving cardiac function, decreasing infarction area, and promoting angiogenesis in peri-infarct area. The protective effects of Shexiang Baoxin pills are partly inhibited by HET0016. Furthermore, Shexiang Baoxin pills enhances the number of circulating endothelial progenitor cells (EPCs) and the expression of the vascular endothelial growth factor (VEGF), based on immunohistochemical analysis, in peri-infarct area of MI rats, which is partly suppressed by HET0016. Conclusions Shexiang Baoxin pills may partially participate in angiogenesis in MI rats. The protective mechanism of Shexiang Baoxin pills may be mediated via up-regulation of 20-HETE, which promotes EPCs mobilization and VEGF expression.
