中文摘要:
      心肌缺血再灌注损伤(MIRI)是指心肌缺血重获血流后对心肌结构和功能造成进一步伤害的现象,是临床治疗中亟待解决的关键问题。研究发现这一过程涉及氧化应激、炎症、细胞凋亡和铁死亡等多个层面。核因子NF-E2相关因子2(Nrf2)是一个对氧化还原变化敏感的转录因子,可通过活化Nrf2有关途径调控下游基因及抗氧化酶表达,发挥抗氧化、抗炎、降低细胞凋亡率和抑制铁死亡等作用缓解MIRI。中医药具有多成分、多靶点、多通路、多层次等作用特点,在防治MIRI方面具有突出优势。本文以Nrf2为切入点,查阅整理近5年的国内外相关文献,发现Nrf2是中医药防治MIRI的核心靶点,对于MIRI具有广泛的保护作用,中药主要发挥活血化瘀、益气养血、清热解毒、补血滋阴等作用激活Nrf2,继而通过介导Nrf2对抗氧化响应元件(ARE)、Kelch样环氧氯丙烷相关蛋白1(Keap1)、血红素氧合酶-1(HO-1)等分子进行靶向调控或协同多个信号通路串扰,发挥抗MIRI的作用。
英文摘要:
      Myocardial Ischemia-Reperfusion Injury (MIRI) refers to the phenomenon in which myocardial tissue suffers further damage to its structure and function after reperfusion following ischemia, representing a key challenge in clinical treatment. Research has shown that this process involves oxidative stress, inflammation, apoptosis, ferroptosis, and other factors. The nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor sensitive to redox changes. It can regulate the expression of downstream genes and antioxidant enzymes through activation of Nrf2-related pathways, exerting antioxidant, anti-inflammatory, anti-apoptotic, and ferroptosis-inhibitory effects to alleviate MIRI. Traditional Chinese medicine (TCM) is characterized by multi-components, multi-targets, multi-pathways, and multi-level effects, which offer prominent advantages in the prevention and treatment of MIRI. This paper focuses on Nrf2 as a research entry point. After reviewing relevant domestic and international literature from the past five years, it is found that Nrf2 is the core target for TCM in the prevention and treatment of MIRI. TCM plays a broad protective role in MIRI by activating Nrf2. The main effects of TCM include promoting blood circulation and removing blood stasis, tonifying Qi and nourishing blood, clearing heat and detoxifying, replenishing blood, and enriching Yin. These actions activate Nrf2, which then mediates the targeted regulation or cooperative interaction of multiple signaling pathways through molecules like antioxidant response elements (ARE), Kelch-like ECH-associated protein 1 (Keap1), heme oxygenase-1 (HO-1), thereby exerting anti-MIRI effects.
