Abstract:
Objective To study astragalus polysaccharide′s synergistic enhancement on Carvedilol′s improvement effects on dilated cardiomyopathy′s heart function.Methods SD rat model of dilated cardiomyopathy was established and divided into CON group (no treatment),CAR group (only Carvedilol treatment),APS group (only astragalus polysaccharide treatment) and C+A group (Carvedilol and astragalus polysaccharide treatment) according to their treatment methods.The left ventricular ejection fraction (LVEF),Tei index,high sensitive C reactive protein (hs-CRP),tumor necrosis factor (TNF)-α,interleukin (IL)-1,IL-6,IL-8,CD3+,CD4+ and CD8+ T lymphocyte subsets in four groups were detected and compared.Results The LVEF in C+A group and CAR group were significantly higher than those in CON group and APS group respectively (P<0.05,respectively),while Tei index in C+A group and CAR group were significantly lower than those in CON group and APS group respectively (P<0.05,respectively).The LVEF in C+A group was significantly higher than that in CAR group (P<0.05),while Tei index in C+A group was significantly lower than that in CAR group (P<0.05).The hs-CRP,TNF-α,IL-1,IL-6 and IL-8 in C+A group and APS group were significantly lower than those in CON group and CAR group respectively (P<0.05,respectively),while CD3+,CD4+ and CD8+ T lymphocyte subsets in C+A group and APS group were significantly higher than those in CON group and CAR group respectively (P<0.05,respectively).The hs-CRP,TNF-α,IL-1,IL-6 and IL-8 in C+A group were significantly lower than those in APS group respectively (P<0.05,respectively),while CD3+,CD4+ and CD8+ T lymphocyte subsets in C+A group were significantly higher than those in APS group respectively (P<0.05,respectively).Conclusion Astragalus polysaccharide has significant synergistic enhancement on Carvedilol′s improvement effects on dilated cardiomyopathy′s heart function,which may be related to the enhancement of T lymphocyte immunity and the decreasing of inflammatory reaction.
