| 摘要: |
| 目的 通过观察心肌缺血再灌注损伤大鼠NO水平、eNOS蛋白和eNOS mRNA表达，探讨丹参通络解毒汤联合骨髓干细胞动员对心肌缺血再灌注损伤大鼠内皮保护作用。方法 大鼠60只，随机分为假手术组、模型组、重组人红细胞生成素（recombinant human erthropoietin，rhEPO）动员组、丹参通络解毒汤组；丹参通络解毒汤联合动员组，每组12只。于造模后14 d采用放射免疫法测定NO水平、免疫组化法测定eNOS蛋白和采用实时荧光定量PCR法测定eNOS mRNA表达。结果 与假手术组比较，各组NO水平，eNOS蛋白和eNOS mRNA表达均明显降低，差异具有统计学意义（P<0.01）；与模型组比较，rhEPO动员组、丹参通络解毒汤组和丹参通络解毒汤联合动员组NO水平升高，eNOS蛋白和eNOS mRNA表达明显提高，差异具有统计学意义（P<0.01）；与rhEPO动员组和丹参通络解毒汤组比较，丹参通络解毒汤联合动员组NO水平显著升高，eNOS蛋白和eNOS mRNA表达明显提高，差异具有统计学意义（P<0.01）。结论 丹参通络解毒汤可以提高缺血心肌eNOS mRNA表达，进一步促进eNOS蛋白表达，升高NO水平，是该方保护心肌缺血再灌注损伤大鼠内皮重要机制之一，同时该方联合动员剂对内皮保护有增强促进作用。 |

| Abstract: |
| Objective To investigate the protective effect of Danshen Tongluo Jiedu decoction combined with bone marrow stem cells mobilization on vascular endothelial cells through observing the changes of NO level, eNOS protein and mRNA eNOS expression in rats with myocardial ischemia reperfusion injury. Methods The 60 rats were randomly divided into sham-operation group, model group, rhEPO mobilization group, Danshen Tongluo Jiedu decoction (DTJD) group, and DanShen TongLuo JieDu decoction combined with rhEPO mobilization (DTJr) group, 12 rats in each group. After 14 days of modeling, the NO level was determiened by radioimmunaossay. The expression of eNOS protein was assessed by immunocytochemistry method, and eNOS mRNA was measured by real-time fluorescence quantitative PCR method. Results Compared with sham-operation group, the levels of NO, eNOS and eNOS reduced significantly (P<0.01). Compared with the IRI group, the levels of NO, eNOS protein and mRNA eNOS expression in rhEPO mobilization group, DTJD group and DTJDr group increased significantly, the differences were statistically significant (P<0.01). Cmpared with rhEPO mobilization group and DTGD group, the level of NO, eNOS protein and mRNA eNOS expression in DTJr group increased significantly, the differences were statistically significant (P<0.01). Conclusion DTJD could improve the expression of eNOS mRNA in endothelial cells and further promote expression of eNOS protein. It is may be one of the mechanisms of protecting endothelial cells in rats with myocardial ischemia reperfusion injury. DTJD combined with mobilization agent could enhance the protective effect on endothelial cells. |
