Effect of Activating Blood to Resolve Stagnation on Cells Expressing CD34 and Vascular Endothelial Growth Factor in Rats with Acute Myocardial Infarction / 中国康复理论与实践

@#Objective To explore the effect of Activating Blood to Resolve Stagnation on the expression of CD34 and vascular endothelial growth factor (VEGF) in rats with acute myocardial infarction. Methods 32 Sprague-Dawley rats were randomly divided into sham operation group (A, n=8), model group (B, n=8), Xuesaitong Injection + granulocyte colony- stimulating factor (G- CSF) group (C, n=8) and G-CSF group (D, n=8). Corresponding medicine was given to each group 3 hours after modeling, for 6 days. Pathomorphological changes were observed through HE staining, and the expression of CD34, VEGF and Ki-67 were observed through immunohistochemical staining. Results The expressions of CD34, VEGF and Ki-67 were higher in groups B, C and D than in group A (P<0.05), and were higher in group groups C and D than in group B (P<0.05). The expressions of CD34 and VEGF were higher in group C than in group D (P<0.05). However, there was no significant difference in the expression of Ki-67 between 2 groups (P>0.05). Conclusion The expression of CD34 and VEGF increases with Activating Blood to Resolve Stagnation method, which is superior to using G-CSF only. Activating Blood to Resolve Stagnation may play an important role in the treatment of acute myocardial infarction.

Objective To explore the effect of Activating Blood to Resolve Stagnation on the expression of CD34 and vascular endotheli-al growth factor (VEGF) in rats with acute myocardial infarction. Methods 32 Sprague-Dawley rats were randomly divided into sham opera-tion group (A, n=8), model group (B, n=8), Xuesaitong Injection + granulocyte colony-stimulating factor (G-CSF) group (C, n=8) and G-CSF group (D, n=8). Corresponding medicine was given to each group 3 hours after modeling, for 6 days. Pathomorphological changes were observed through HE staining, and the expression of CD34, VEGF and Ki-67 were observed through immunohistochemical staining. Re-sults The expressions of CD34, VEGF and Ki-67 were higher in groups B, C and D than in group A (P0.05). Conclusion The expression of CD34 and VEGF in-creases with Activating Blood to Resolve Stagnation method, which is superior to using G-CSF only. Activating Blood to Resolve Stagna-tion may play an important role in the treatment of acute myocardial infarction.
