Abstract:
In this study,transcriptomics technique was used to investigate the mechanism of action of Aconiti Lateralis Radix Praeparata on acute heart failure rats induced by propafenone hydrochloride.First,rats were randomly divided into normal group,model group and administration group(1.25,2.5,5 g·kg-1).A rat with acute heart failure was constructed by intravenous femoral administration of proparone hydrochloride.The changes of heart rate,+dp/dtmaxand-dp/dtmaxat 5,10,20,30 and 60 min were recorded.Then another group of rats were given the same drug delivery method.In another group of animals,serum TNF-α could be determined by ELISA with the same dosage method.High-throughput sequencing technology was used to detect all gene expression differences in cardiac tissue samples of rats with acute heart failure.Through functional annotation and enrichment analysis,gene expression signaling pathways of rats with acute heart failure and rats with post-administration heart failure were screened out.The results showed that heart rate and LV+dp/dtmaxand LV-dp/dtmaxwere significantly decreased in the model group(P<0.05),while heart rate and LV+dp/dtmax and LV-dp/dtmaxwere significantly increased in the drug group(P<0.05,P<0.01).Moreover,ANP,BNP and TNF-α in acute heart failure rats was significantly decreased in high-dose aconite decoction group(P<0.05).Transcriptomics analysis showed that the mechanism of action was mainly related to activation of PI3 K-AKT signaling pathway and Jak-STAT pathway.Compared with the model group,aconite decoction up-regulated the expression of phosphatidylinostol 3-kinase(PI3 K),lysophosphatidic acid(LAP3),Bcl-3 and STAT genes,and down-regulated the expression of integrin(ITGA),nuclear orphan receptor(Nur77) genes.It could be concluded that the mechanism of aconite in treating acute heart failure rats may be related to the regulation of the PI3 k-Akt/Jak-STAT pathway.
