OBJECTIVE: To study the effect of dexmedetomidine (Dex) on myocardial injury induced by acute kidney injury (AKI) in diabetes mellitus rats and explore the potential mechanisms.
METHODS: The Type 2 diabetes mellitus (T2DM) model was prepared in 40 adult male Wistar rats. These rats were randomly divided into four groups (n=10/group), including the control (Con) group, AKI group, Dex preconditioning (DPreC) group, and resveratrol (Res) combined with Dex preconditioning (Res+DPreC) group. The AKI model was prepared in the AKI, DPreC, and Res+DPreC group. The DPreC group received Dex, while the Con and AKI group received normal saline. The Res+DPreC group received Res in addition to Dex preconditioning. Histopathologic, apoptotic, enzymatic, and inflammatory changes in myocardial tissue were observed or detected.
RESULTS: Histopathologic, apoptotic, and enzymatic changes in myocardial tissue demonstrated that AKI induced myocardial injury in T2DM rats; Dex preconditioning could mitigate this injury; and RES enhanced this effect. Inflammatory changes suggested that Dex alleviated the inflammatory response induced by AKI in T2DM rats via regulating the expressions of SIRT1, TNF-α, IL-17A, and IL-10.
CONCLUSIONS: Dex could alleviate myocardial injury induced by AKI in DM rats via regulating the inflammatory response associated with SIRT1, TNF-α, IL-17A, and IL-10, and Res could enhance this protective effect.
