谵妄动物模型和评价方法研究进展

Research progress in animal models of delirium and their evaluation methods

谵妄是以意识模糊、思维混乱和注意力集中困难为特征的急性脑功能障碍综合征,主要影响ICU和老年住院患者。其不仅治疗成本高昂,还可能导致严重并发症及死亡率增加。由于其病因复杂、病理机制不明,临床对谵妄的药物治疗很大程度是无效的。而构建动物模型是理解谵妄疾病机制、筛选新药和研究干预措施的有力工具。本文通过回顾国内外近年来谵妄动物模型相关的实验研究,从动物选择、模型构建方法、模型评价三个方面总结谵妄动物模型构建及评价方法的最新进展,为基于谵妄动物模型开展的实验研究提供参考。

Delirium is an acute brain dysfunction syndrome characterized by confusion and difficulty concentrating,which mainly affects intensive care unit patients and elderly inpatients.Treatment is expensive and may also lead to increased risks of serious complications and death.The complex etiology and unknown pathological mechanisms of delirium mean that clinical drug treatment is largely ineffective.Animal models therefore provide a powerful tool to help understand the mechanism of delirium,screen new drugs,and study potential intervention measures.We review experimental research related to delirium animal models worldwide,and summarize the latest progress in the construction and evaluation of these models from the aspects of animal selection,model construction method,and model evaluation,to provide a reference for further experimental research based on delirium animal models.
