摘要:

背景  局麻药(local anesthetic, LA)广泛用于神经阻滞、镇痛,其可能引起的神经毒性引起了麻醉医生的关注,其中关于此种毒性作用机制的研究取得了较大的进展。 目的 分析总结各种丝裂原活化蛋白激酶家族(mitogen-activated protein kinases, MAPKs)成员在LA神经毒性中的作用。 内容 越来越多的证据证明LA的神经毒性作用可能与细胞凋亡有关。MAPKs是一种广泛存在细胞内的丝氨酸/苏氨酸蛋白激酶,在细胞凋亡过程中发挥重要作用。故MAPK信号通路逐渐成为LA毒性作用研究中的重点,其中关于细胞外信号调节激酶(extracellular signal-regulated kinase, ERK), c-Jun N-末端激酶(c-jun nterminal kinase, JNK)以及p38MAPK信号转导通路的研究较为成熟。 趋向 MAPKs在LA神经毒性的具体机制中发挥重要作用,这为LA的临床应用及毒性作用防治提供依据和理论指导。

Abstract:

Background The potential toxicity is a well-known side effect of local anesthetics (LA) which is widely used in nerve block and analgesia. The mechanisms of local anesthetic toxicity were further investigated. Objective This review summarized the recent studies examining the mitogen-activated protein kinases (MAPKs) signaling pathway and their regulation, and discussed the effects of MAPKs on neurotoxicity of LA. Content Accumulating evidences indicate that neurotoxicity of LA is related to apoptosis. MAPKs, a serine-threonine protein kinase family, play a crucial role in apoptosis of cells. So that the effects of MAPKs signaling pathway on neurotoxicity of LA is becoming a hot issue to be researched. And the impact of extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), p38MAPK are more concerned. Trend The MAPKs signaling pathway and their regulation play an important part in the underlying mechanisms of local anesthetic neurotoxicity which could provide evidences and theory for clinical use of LA.
