Abstract:
ObjectiveThis study was designed to observe the effect of Didang Xianxiong decoction on the cardiac myocardial microvascular endothelial cells （CMECs） injury， and to explore its related mechanism based on the CMECs model induced by high glucose. MethodRat primary myocardial cells were cultured in vitro and 33 mmol·L-1 glucose was added for modeling. After modeling， the rats were randomly divided into model group （final glucose concentration： 33 mmol·L-1）， normal group， Didang Xianxiong decoction low dose group （glucose + 5% Didang Xianxiong decoction containing serum）， Didang Xianxiong decoction medium dose group （glucose+10% Didang Xianxiong decoction containing serum）， Didang Xianxiong decoction high dose group （glucose+20% Didang Xianxiong decoction containing serum） and alagebrium chloride （ALT-711） group （glucose+10% ALT-711 containing serum）. The influence of drug-containing serum on the proliferation of CMECs was detected by MTT tetrazolium salt colorimetric assay. The relative mRNA expression of c-Jun was detected by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The protein expression of phosphorylated Janus kinase 1 （p-JAK1）， phosphorylated signal transducer and activator of transcription 1 （p-STAT1） and transforming growth factor-β1 （TGF-β1） was determined by Western blot. ResultCompared with the conditions in normal group， the mRNA expression of c-Jun and protein expression of p-JAK1， p-STAT1 and TGF-β1 were up-regulated in model group （P<0.01）. Compared with model group， all treatment groups had decreased mRNA expression of c-Jun （P<0.01）. Didang Xianxiong decoction medium and high dose groups and ALT-711 group showed reduced protein expression of p-JAK1 and p-STAT1 （P<0.05， P<0.01）， while there was no significant change in Didang Xianxiong decoction low dose group. TGF-β1 protein expression was lowered in all treatment groups （P<0.05， P<0.01）， and the decrease was more significant in Didang Xianxiong decoction medium and high dose groups than Didang Xianxiong decoction low dose group. ConclusionDidang Xianxiong decoction can protect CMECs with high glucose-induced injury， and the mechanism may be related to reducing the activity of JAK/STAT signaling pathway in cells.
