摘要:

脓毒症及其引起的肺损伤严重威胁人类健康。右美托咪啶(DEX)作为镇静药物,在防治脓毒症肺损伤的基础与临床实践中发挥了积极作用。本文从炎症反应、氧化应激、细胞凋亡、线粒体动力学、细胞自噬、血管通透性、神经调节以及靶向miR-128-3p/MAPK14、DNA甲基化等方面综述了DEX减轻脓毒症肺损伤的作用与机制,以期深入理解DEX在重症医学领域中的应用,扩展DEX的药理学作用,从镇静角度为防治脓毒症提供新的思路。

Abstract:

The sepsis and sepsis-induce lung injury threats seriously human health. Dexmedetomidine (DEX), a sedative drug, plays an active role in preventing sepsis-induced lung injury during the basic and clinical practice. The current article reviews the role and mechanism of DEX dexmedetomidine alleviating sepsis-induced lung injury from the aspects of inflammation, oxidative stress, apoptosis, mitochondrial dynamics, autophagy, vascular permeability, neuro-regulation, targeting miR-128-3p/MAPK14 and DNA methylation, etc. This review looks forward to deepen the understanding the application of DEX in the field of critical care medicine, expand the pharmacological effect of DEX and provide a new idea for the prevention and treatment of sepsis from the sedation approach. 

Key words: dexmedetomidine, sepsis, acute lung injury ,
