摘 要:目的:观察益气活血复方对mt TFA在心力衰竭大鼠中表达的影响。方法:大鼠80只,随机选取20只为正常组,余大鼠经左冠状动脉前降支结扎法配合力竭式游泳、节食等方法造成慢性心衰模型,将造模成功大鼠分为模型组、中药组、西药组,共4组,均以灌胃给药或蒸馏水28 d。利用蛋白免疫印迹法和RT-PCR法分别检测线粒体转录因子A(mitochondrial transcription factor A,mt TFA)的蛋白和基因表达的变化情况,比色法测定高能磷酸盐(adenosine triphosphate,ATP)浓度,ELISA法测定血清脑钠素(brain natriuretic peptide,BNP)的浓度。结果:与正常组相比,模型组及余各组大鼠ATP及mt TFA水平显著降低(P<0.01),BNP含量显著升高(P<0.01);与模型组相比,中药组和西药组ATP及mt TFA明显升高(P<0.01),BNP含量明显降低(P<0.01);西药组与中药组血清中ATP,mt TFA及BNP含量无明显差异(P>0.05)。结论:益气活血中药可显著降低心衰大鼠BNP的含量水平,改善线粒体能量代谢,改善心功能,促进mt TFA生成,可抑制或逆转心室重构的过程,从而有抗心力衰竭的作用。Objective:To observe the effect of Yiqi Huoxue Decoction on the expression of mtTFA in heart failure in rats. Methods:80 rats were randomly selected,20 were normal group, the other rats by left anterior descending coronary ar- tery ligation method with the exhaustive method type swimming, diet to establish chronic heart failure model. The success- ful model rats were divided into model group, Chinese medicine group, western medicine group, a total of 4 groups, all with intragastric administration or distilled water for 28 days. We detected mitochondrial transcription factor A by protein immu- noblotting and RT - PCR ( mitochondrial transcription factor A, mtTFA) changes of the expression of proteins and genes, determination of high - energy phosphate Colorimetry ( adenosine triphosphate, ATP) concentration, the determination of serum brain natriuretic peptide ELISA ( brain natriuretic peptide, BNP) concentration. Results : Compared with normal group, model group and the other groups ATP and mtTFA levels were significantly decreased ( P 〈 0. 01 ) and the content of BNP increased significantly (P 〈 0.01 ) ; compared with the model group ,Chinese medicine group and Western medi- cine group ATP and mtTFA were increased significantly ( P 〈 0.01 ) and the content of BNP was decreased ( P 〈 0.01 ) ; the western medicine group and Chinese medicine group had no significant difference in serum ATP, mtTFA and BNP con- tent ( P 〉 0.05 ). Conclusion : Yiqi Huoxue Decoction can significantly reduce the levels of BNP in heart failure rats, im- prove mitochondrial energy metabolism,improve heart function, promote the formation of mtTFA and can inhibit or reverse remodeling process, and thus play the role of anti heart failure.
