摘要:

背景:急性梗死心肌修复过程中,寻找可有效提高外周血骨髓间充质干细胞的数量、并动员其定向归巢于损伤心肌的骨髓间充质干细胞动员剂尤为关键。

目的:探讨养心通脉有效部位方对急性心肌梗死大鼠骨髓间充质干细胞动员入血及定向归巢于梗死心肌的影响。

方法:养心通脉有效部位方主要成分包括人参皂苷、丹参酮ⅡA、总生物碱、人参多糖等,由中南大学药学院依课题组稳定的制作工艺制作提供。SD大鼠70只,取8只大鼠作为正常对照组,剩余62只大鼠建立急性心肌梗死模型。取造模成功的32只大鼠,随机分为养心通脉有效部位方组、复方丹参注射液组、重组人粒细胞集落刺激因子组、模型对照组,各组均于造模3 h后给与对应药物,连续5 d。流式细胞仪检测外周血CD34+细胞数,免疫组化染色检测梗死心肌边缘区CD34+细胞数。

结果与结论:与模型对照组比较,重组人粒细胞集落刺激因子组、养心通脉有效部位方组外周血CD34+细胞数均明显增加(P < 0.01);心肌梗死边缘区胞浆CD34+细胞数均显著增加(P < 0.01)。与重组人粒细胞集落刺激因子组比较,养心通脉有效部位方组心肌梗死边缘区胞浆CD34+细胞数显著增加(P < 0.01)。养心通脉有效部位方能促进骨髓干细胞动员入血,并定向归巢于梗死心肌,其作用与重组人粒细胞集落刺激因子大体相当,在归巢CD34+细胞方面甚至强于重组人粒细胞集落刺激因子,是一种良好的骨髓间充质干细胞动员剂。

Abstract:

BACKGROUND: During acute infarct myocardium repair process, it is important to seek mobilization agent that can elevate number of peripheral blood bone marrow mesenchymal stem cells (BMSCs) and induce BMSCs homing to damaged myocardium.

OBJECTIVE: To explore the effect of active principle region of Yangxin Tongmai Formula (apr-YTF) on the BMSC mobilization and homing of infarct myocardium in rats.

METHODS: The apr-YTF was primarily composed of ginsenoside, tanshinone ⅡA, total alkaloids, and panaxan, which was supplied by College of Pharmacy, Central South University in accordance with the technique of this group. Among 70 Sprague Dawley rats, 8 rats were considered as normal control group, and the remaining 62 rats was used to establish models of acute myocardial infarction. A total of 32 rat models were randomly assigned to apr-YTF group, Danshen injection group, recombinant human granulocyte colony stimulating factor (rhG-CSF) group and model control group. After 3-hour modeling, corresponding drugs were given in each group for 5 days. Peripheral blood CD34+ cell number was determined using flow cytometry. CD34+ cell number was detected at marginal zone surrounding the infarct myocardium utilizing immunohistochemical staining.

RESULTS AND CONCLUSION: Number of peripheral blood CD34+ cells increased significantly in the rhG-CSF group and apr-YTF group compared with model control group (P < 0.05). CD34+ cell number at marginal zone surrounding the infarct myocardium increased significantly (P < 0.01). Compared with the rhG-CSF group, CD34+ cell number at marginal zone surrounding the infarct myocardium increased significantly in the apr-YTF group (P < 0.01). The apr-YTF could promote BMSCs mobilization into blood, and directly homing to infarct myocardium. Its effects were identical to rhG-CSF. The effects on homing of CD34+ cells were better than rhG-CSF. It was a good agent for BMSCs mobilization.
