通过血生化证明心梗会导致心肌梗死小鼠活性氧含量升高,促进乳酸脱氢酶的释放,抑制超氧化物歧化酶(SOD)活性,并提高丙二醛(MDA)水平,通过HE染色、MASSON染色和天狼猩红染色发现假手术组小鼠细胞核呈椭圆形且完整,排列紧密整齐,胶原沉积很少,模型组细胞数量较假手术组减少,具有细胞凋亡现象,排列不规则并产生炎性细胞,细胞间隙增宽胶原纤维沉积更加严重,说明心梗线粒体损伤造成了心肌纤维化。
综上所述,我们得出:心梗对于心脏的损伤是及其严重的,并且至今未能找到痊愈的解决方案,而据研究活血川归剂的君药当归和川芎对于氧化应激等损伤有明显的治疗效果。因此,我们接下来的实验将围绕WB、PCR、线粒体相关功能检测,研究活血川归剂通过干预PGC-1α/Sirt3通路及上下游相关因子,上调Sirt3和PGC-1α,调控心梗线粒体功能相关基因的表达,进而减轻心肌纤维化的机制。
