摘要: 缺血性卒中(又称脑梗死)作为导致全球残疾和死亡的主要原因之一,近年来,其预后生物标志物的研究取得了显著进展。本文综述了包括血细胞分析指标(如红细胞体积分布宽度)、ω-3多不饱和脂肪酸、细胞因子(如白介素6、肿瘤坏死因子α)、微小核糖核酸(miRNA,如miR-21、miR-155、miR-126)和外泌体在内的多种生物标志物在缺血性脑卒中中的作用机制及其在预后评估中的研究进展。综述得出,血细胞分析相关指标、ω-3多不饱和脂肪酸、白介素6、肿瘤坏死因子α的浓度与缺血性脑卒中的严重程度和预后密切相关。其中,较高基线红细胞体积分布宽度与复发性缺血性脑卒中的风险增加相关,并且与缺血性脑卒中的复发时间呈负相关。特定miRNA(如miR-21)通过抑制细胞凋亡和促进神经元存活,改善神经功能恢复;而miR-155通过调控炎症反应加剧脑损伤,其表达水平可预测缺血性脑卒中的复发;此外,miR-126在血管生成和神经保护中发挥关键作用。外泌体则通过携带抗炎因子、神经营养因子、抗氧化酶和热休克蛋白等,显著减轻缺血再灌注引起的炎症和损伤,从而影响缺血性脑卒中的预后。尽管这些生物标志物在缺血性脑卒中预后评估中显示出巨大潜力,但其临床应用仍面临诸多挑战,包括个体间差异、长期效应和安全性研究不足以及技术标准化问题。未来研究应进一步探讨这些标志物的作用机制,开发标准化的检测方法,并进行大规模临床验证,以便将其应用于临床,改善缺血性脑卒中患者的预后和生活质量。

Abstract:

Ischemic stroke (IS) is one of the leading causes of disability and death worldwide. Various biomarkers closely associated with IS prognosis have been identified in recent years. This paper reviewed the mechanisms of action of blood cell analysis related indicators, omega-3 polyunsaturated fatty acids, IL-6, TNF-α, miRNA, and extracellular vesicles in ischemic stroke and their research progress as predictive biomarkers. The concentrations of blood cell analysis related indicators, omega-3 polyunsaturated fatty acids, IL-6 and TNF-α were closely related to the severity and prognosis of IS. Among them, a higher baseline red blood cell volume distribution width was associated with an increased risk of recurrent ischemic stroke, and was negatively correlated with the recurrence time of ischemic stroke. miR-21 improved neuronal functional recovery by inhibiting apoptosis and promoting neuronal survival, while miR-155 exacerbated brain injury by regulating inflammatory responses, with its expression level predicting IS recurrence. Moreover, miR-126 played a crucial role in angiogenesis and neuroprotection. Extracellular vesicles, carrying anti-inflammatory factors, neurotrophic factors, antioxidant enzymes, and heat shock proteins, mitigate inflammation and damage caused by ischemia-reperfusion, significantly influencing IS prognosis. Despite the tremendous potential of these biomarkers in IS prognosis assessment, their clinical application faced several challenges, including interindividual differences, inadequate research on long-term effects and safety, and issues with technical standardization. Future research should focus on elucidating the mechanisms of action of these biomarkers, developing standardized detection methods, and conducting large-scale clinical validation, to apply them in clinical practice to improve the prognosis and quality of life of IS patients.
