摘要:

脑缺血时,骨髓间充质干细胞从骨髓中动员,经外周循环,发挥促神经再生作用,但是骨髓间充质干细胞动员进入外周循环的数量不足以达到治疗作用。研究显示中医活血化瘀方法能影响干细胞归巢。血塞通软胶囊是活血化瘀使用的主要药物之一,其主要成分是三七总皂甙。实验采用大脑中动脉闭塞方法建立脑梗死大鼠模型,持续28d灌胃血塞通软胶囊20,40,60 mg/kg/d。ELISA检测结果发现,中、高剂量血塞通能明显增加脑梗死大鼠血液和骨髓中干细胞因子的水平及骨髓干细胞标志物CD117阳性细胞数量,降低大鼠外周血和骨髓中细胞黏附因子CD54,CD106阳性细胞数量,但低剂量血塞通效果不明显。表明较高浓度的血塞通可促进外周血中骨髓间充质干细胞动员,提示一定浓度的三七总皂苷可以提高血浆中骨髓间充质干细胞动员的水平。

Abstract:

After cerebral ischemia, bone marrow mesenchymal stem cells are mobilized and travel from the bone marrow through peripheral circulation to the focal point of ischemia to initiate tissue regeneration. However, the number of bone marrow mesenchymal stem cells mobilized into peripheral circulation is not enough to exert therapeutic effects, and the method by which blood circulation is promoted to remove blood stasis influences stem cell homing. The main ingredient of Xuesaitong capsules is Panax notoginseng saponins, and Xuesaitong is one of the main drugs used for promoting blood circulation and removing blood stasis. We established rat models of cerebral infarction by occlusion of the middle cerebral artery and then intragastrically administered Xuesaitong capsules (20, 40 and 60 mg/kg per day) for 28 successive days. Enzyme-linked immunosorbent assay showed that in rats with cerebral infarction, middle- and high-dose Xuesaitong significantly increased the level of stem cell factors and the number of CD117-positive cells in plasma and bone marrow and significantly decreased the number of CD54- and CD106-positive cells in plasma and bone marrow. The effect of low-dose Xuesaitong on these factors was not obvious. These findings demonstrate that middle- and high-dose Xuesaitong and hence Panax notoginseng saponins promote and increase the level and mobilization of bone marrow mesenchymal stem cells in peripheral blood.
