Abstract:
ObjectiveTo explore the effects ofYixintaiGranules on expression of C-Myc mRNA and its protein in myocardial tissues of rabbits with chronic heart failure (CHF).Methods CHF rabbit models were established by ear marginal vein injection of adriamycin. Successfully modeled rabbits were divided into the model group, the Losartan Potassium group, the high-, medium-, and low doseYixintaiGranules groups. Besides, a normal control group was set up. Administration groups were given relevant medicine for gavage, equal volume of physiological saline was administered to rabbits of the model group and the normal control group by gastrogavage. The intervention lasted for 4 weeks, once per day. Echocardiographic indexes and mRNA and protein expression levels of C-Myc in myocardial tissue were detected after 4 weeks of medication.Results Compared with the normal group, the LVEF, LVFS, and E/A of the model group decreased significantly (P<0.01), but mRNA and protein expression levels of C-Myc in myocardial tissues increased significantly (P<0.01). Compared with the model group, the LVEF, LVFS, and E/A of YG groups and Losartan Potassium group increased significantly (P<0.01), but mRNA and protein expression levels of C-Myc in myocardial tissues decreased significantly (P<0.05,P<0.01).ConclusionYixintaiGranules can effectively inhibit the expression of mRNA and protein expression of C-Myc, and improve cardiac function.
