Protective Effect of Astragaloside Ⅳ Combined with Hydroxysafflor Yellow A on Mice with Myocardial Infarction
Objective:To observe the effect of pretreatment with astragaloside Ⅳ combined with hydroxy safflower yellow A on myocardial infarction area
cardiomyocyte apoptosis and expression of inflammatory cytokines in mice with myocardial infarction. Method:Totally 50 SPF grade C57 mice (half male and half female) were randomly divided into sham operation group (Sham)
myocardial infarction model group (MI)
astragaloside pretreatment group (MI + As Ⅳ
3.5 mg·kg-1)
hydroxy safflower yellow A pretreatment group (MI + HSYA
10 mg·kg-1)
and astragaloside Ⅳ + hydroxy safflower yellow A pretreatment group (MI + As Ⅳ + HSYA
3.5 mg·kg-1+10 mg·kg-1). Intraperitoneal injection lasted for 7 days before modeling
once a day. The model of myocardial infarction was established by ligating left anterior descending coronary artery. The infarction area
ischemic area and total left ventricle area of myocardium were distinguished by evans blue-TTC double staining method. ImageJ software was used to calculate the myocardial infarction area
the expressions of Bax
Bcl-2 and cleaved-Caspase-3 in myocardium were detected by Western blot. The levels of serum interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected by enzyme-linked immunosorbent assay (ELISA) content. Result:Compared with the model group
the pretreatment group and the combined pretreatment group could significantly reduce the myocardial infarction area of the mice
and the effect of the combined treatment group was better than that of the single pretreatment group. Compared with the sham group
the ischemic area and infarction area of the model group were increased
and the ischemic area and infarction area of the combination group and the combined administration group were decreased(P<0.05
P<0.01). Compared with the model group and the sham operation group
astragaloside Ⅳ combined with hydroxy safflower yellow A up-regulates the expression of anti-apoptotic protein Bcl-2 incardiomyocytes
and down-regulates the expressions of cleaved-Caspase-3 and Bax(P<0.05
P<0.01). Astragaloside Ⅳ combined with hydroxysafflor yellow A can reduce the levels of IL-6 and TNF-α in serum of mice with myocardial infarction(P<0.05
P<0.01). Conclusion:Astragaloside Ⅳ combined with hydroxy safflower yellow A can reduce the myocardial infarction area in mice
and inhibit myocardial cell apoptosis and inflammatory response after myocardial infarction
