摘要:


文题释义:

右旋美托咪定:是一种高度特异性的α2肾上腺素能受体激动剂,具有镇痛、镇静、抗焦虑、抗交感神经和阿片类药物保护作用。右旋美托咪定主要通过调节基因表达、通道激活、递质释放、炎症过程以及细胞的凋亡和坏死,已经被证明在各种缺血再灌注损伤的模型中具有器官保护作用。
缺血再灌注损伤:多数情况下,缺血后再灌注可使组织器官功能得到恢复,损伤的结构得到修复,患者病情好转康复,但有时缺血后再灌注不仅不能使组织、器官功能恢复,反而加重组织、器官的功能障碍和结构损伤。这种在缺血基础上恢复血流后组织损伤反而加重,甚至发生不可逆性损伤的现象称为缺血再灌注损伤。


背景:右旋美托咪定具有抗缺血再灌注损伤的作用,但对其信号通路全面、系统的综述较少。

目的:重点对右旋美托咪定在抗氧化应激、抑制炎症、抗凋亡、自噬等机制方面的信号通路进行综述。
方法:计算机检索PubMed 数据库、中国知网、万方数据库及维普数据库的相关文章,英文检索词为“ischemia-reperfusion injury,dexmedetomidine,signal path,oxidative stress,inflammation,apoptosis”;中文检索词为“缺血再灌注损伤,右旋美托咪定,信号通路,氧化应激,炎症,凋亡”。排除重复性研究及部分相关性较低的基础类文章,最终纳入57篇文献进行评价。

结果与结论:①右旋美托咪定主要通过抗氧化应激损伤、抗炎、抗细胞凋亡和自噬等多种机制发挥器官保护作用,这其中又涉及众多通路,主要包括Nrf2及其下游蛋白抗氧化应激通路、Toll样受体4家族和核因子κB相关抗炎通路、JAK2/STAT3相关抗炎通路、胆碱能抗炎通路,而且胆碱能通路是众多核因子κB信号通路的上游机制;②PI3K/Akt通路依据其激活的下游信号不同发挥不同的作用,抑制NLRP3炎性体激活,激活内皮型一氧化氮合酶、哺乳动物雷帕霉素靶蛋白、缺氧诱导因子1α等信号分子发挥抗炎作用,激活Bad或Bax残基发挥抗凋亡作用,PI3K/Akt激活糖原合成酶激酶3β可同时发挥抗炎、抗凋亡作用;③右旋美托咪定激活SIRT3介导抗细胞凋亡作用,抑制内质网应激产生抗凋亡作用;④针对右旋美托咪定抗缺血再灌注损伤信号通路的详细综述,能为将来的机制研究及诊疗决策提供依据。

Abstract: BACKGROUND: Dexmedetomidine has the effect of anti-ischemia-reperfusion injury, but the comprehensive and systematic review of its signaling pathway is less.  
OBJECTIVE: To focus on the review of dexmedetomidine’s signaling pathway in the mechanisms of antioxidant stress, inhibition of inflammation, anti-apoptosis, autophagy, and so on.
METHODS: The relevant articles on PubMed, CNKI, WanFang, and VIP databases were searched by computer with the key words “ischemia-reperfusion inquiry; dexmedetomidine; signal path; oxidative stress; inflammation; apoptosis” in Chinese and English. After excluding repetitive research and some basic articles with low correlation, 57 articles were finally included for review.  
RESULTS AND CONCLUSION: (1) Dexmedetomidine plays an important role in organ protection through many mechanisms, such as anti-oxidative stress injury, anti-inflammation, anti-apoptosis and autophagy. This involves many pathways, including Nrf2 and its downstream protein antioxidant stress pathway, Toll-like receptor 4 family and nuclear factor-κB-related anti-inflammatory pathway, JAK2/STAT3-related anti-inflammatory pathway, and cholinergic anti-inflammatory pathway, and the cholinergic pathway is the upstream mechanism of many nuclear factor-κB signaling pathways. (2) PI3K/Akt pathway plays different roles according to its activated downstream signals, inhibiting the activation of NLRP3 inflammatory body, activating signal molecules endothelial nitric oxide synthase, mammalian target of rapamycin, and hypoxia-inducible factor 1α to play an anti-inflammatory role, and activate Bad or Bax residues to play an anti-apoptotic role, and PI3K/Akt activates glycogen synthetase kinase-3β. It can also play an anti-inflammatory and anti-apoptotic role. (3) Dexmedetomidine activates SIRT3 to mediate anti-apoptosis and inhibit endoplasmic reticulum stress to produce anti-apoptosis. (4) The detailed review of the anti-ischemia-reperfusion injury signaling pathway of dexmedetomidine can provide a basis for future mechanism research and diagnosis and treatment decisions.

Key words: ischemia-reperfusion injury, dexmedetomidine, signaling pathway, oxidative stress, inflammation, apoptosis
