Objective To observe effect and possible mechanism of Guanxin Shutong Jiaonang( 冠心舒通胶囊)on myocardial energy metabolism of chronic heart failure model rats after myocardial infarction. Methods Twenty of eighty SD rats were randomly selected as the blank group
and the others were copied to rats model with chronic heart failure used ligation of left coronary artery anterior descending branch cooperated with exhausting swimming and diet. Rats with successful model were randomly divided into model group
western medicine group and Guanxin Shutong Jiaonang group. The western medicine group was given lisinopril 1. 5 mg /( kg·d) to gavage. The Guanxin Shutong Jiaonang group was given Guanxin Shutong Jiaonang 10. 0 g /( kg·d) to gavage. The blank group and the model group were respectively given distilled water 3 ml each time to gavage
once a day. After 28 days
the researchers measured plasma b-type natriuretic peptide( BNP)
triphosadenine( ATP)
gene and protein expression of peroxisome proliferator-activated receptor γ auxiliary activation factor 1α( PGC-1α)
nuclear respiratory factor 1( NRF)and mitochondrial transcription factor A( mt TFA) of myocardial tissue in rats of each group. Results Compared with the blank group
plasma BNP level increased in the model group
the western medicine group and the GuanxinShutong Jiaonang group but plasma ATP concentration and PGC-1α
NRF-1
mt TFA mRNA and protein expression of myocardial tissue decreased( P < 0. 05). Compared with the model group
plasma BNP level of the western medicine group and the Guanxin Shutong Jiaonang group decreased but ATP concentration
PGC-1α
NRF-1
mt TFA mRNA and protein expression increased( P < 0. 05)
and the inter-group difference had no statistical significance between the western medicine group and the Guanxin Shutong Jiaonang group( P > 0. 05). Conclusion Guanxin Shutong Jiaonang may improve and correct heart failure by activating PGC-1α
NRF-1
mt TFA factor associated with myocardial energy metabolism and increasing capacity of mitochondria.
