This study aims to explore the changes of myocardial sulfhydryl oxidoreductase system and its role in cardiac injury in type 2 diabetic rats. The study randomly divided type 2 diabetic rats into control group and model group. The pathological changes of heart tissue were observed by H&E staining and Masson staining. The expression levels of myocardial sulfhydryl oxidoreductase system related proteins and genes were detected by Western blot and real-time PCR technique. The results showed that the heart tissue pathological injury of type 2 diabetic rats was significant, and the expression levels of myocardial sulfhydryl oxidoreductase system related proteins and genes were also significantly changed. Further analysis showed that the imbalance of myocardial sulfhydryl oxidoreductase system was one of the important mechanisms of type 2 diabetes-induced cardiac injury. Therefore, the results of this study will provide important reference for further exploring the pathogenesis of type 2 diabetes-induced cardiac injury.精品文档---下载后可任意编辑【Key words】Type 2 diabetes; cardiac injury; myocardial sulfhydryl oxidoreductase system; chronic inflammatory reaction.
