Abstract:
Objective To investigate the effects of Shexiangbaoxin pills (SXBXP) on the serum levels of T helper type 1 (Th1) cytokines including tumor necrosis factor-a (TNF-α),interferon-γ(IFN-γ) and T helper type 2 (Th2) cytokines incloding interleukin-4 (IL-4),interleukin-10 (IL-10)in rats with chronic heart failure (CHF).Methods The CHF models were established by left anterior descending coronary artery ligation.Fifty-four Wistar rats were randomly divided into six groups:control group,sham operation group,CHF model group,small dose SXBXP group,large dose SXBXP group and positive medicine group.Heart function was examined by echocardiography before and after therapy,the TNF-α and IL-10 levels were measured by radioimmunoassay,IFN-γ and IL-4 levels were measured by enzyme linked immunosorbent assay (ELISA).Results (1) Before therapy,there was no significant difference between control group and sham operation group in ejection fraction of left ventricle (LVEF).Compared with control group and sham operation group,the levels of LVEF were significantly decreased in CHF model group,small dose SXBXP group,large dose SXBXP group and positive medicine group (all P＜0.01).(2) After therapy,compared with sham operation group,the serum levels of TNF-α and IFN-γ were markedly increased,and IL-4 and IL-10 were significantly decreased in CHF model group (all P＜0.01 ).Compared with CHF model group,LVEF was significantly improved,serum levels of TNF-α and IFN-γ were markedly decreased,IL-4 and IL-10 were markedly increased in large dose SXBXP group (all P＜0.05).In small dose SXBXP group,serum levels of IFN-γ were markedly decreased and IL-10 were markedly increased (all P＜0.05).In positive medicine group,serum levels of TNF-α and IFN-γ were markedly decreased and IL-10 were markedly increased (all P＜0.05).In small dose SXBXP group and positive medicine group,serum levels of IL-4 increased and LVEF decreased,even though there was no significant difference compared with CHF model group.Conclusions The SXBXP therapy of rats with CHF induced by myocardial infarction improves the heart function,decreases the serum levels of TNF-α and IFN-γ,and increases serum levels of IL-4 and IL-10.
