Methods: Local cerebral ischemia-reperfusion rat model was established with modified Zea-Longa thread-occlusion method, and MSCs were injected into the caudal vein, and Buyang Huanwu Tang(补阳还五汤)was administrated. Vascular endothelial growth factor (VEGF) and Ki-67 expression in the ischemic side of the brain in the cerebral ischemic-reperfusion rat were detected with immuno-histochemical staining method. Results: VEGF and Ki-67 expressions were significantly up-regulated in the MSCs group and the combination group, with significant differences as compared with the model group and the sham operation group (P<0.05), and with the most strongest effect in the combination group. Conclusion: Buyang Huanwu Tang(补阳还五汤)combined with MSCs transplantation repairs the injured blood vessels and lesion tissues possibly by up-regulation of VEGF and Ki-67 expression.展开更多
