摘要：

血清尿酸作为人体内天然抗氧化剂，近年发现其与多种神经变性病的发生与发展相关，包括帕金森病、多系统萎缩、阿尔茨海默病和肌萎缩侧索硬化症等。血清尿酸水平升高可以减少帕金森病和肌萎缩侧索硬化症的发病风险，但与多系统萎缩和阿尔茨海默病等神经变性病的关系尚不明确。体外研究和动物实验证实血清尿酸水平升高可以增强神经元抗氧化应激能力，从而延缓神经元变性和凋亡。本文拟对近年来血清尿酸与神经变性病的研究进展进行综述，以为探寻神经变性病新的预防与治疗策略提供信息。

Abstract:

Serum uric acid (sUA), a natural antioxidant in human body, has been found to be related to the occurrence and development of various neurodegenerative diseases in recent years, including Parkinson's disease (PD), multiple system atrophy (MSA), Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS). Increasing of sUA level has been found to reduce the incidence of PD and ALS, but the relationship between sUA and AD, MSA remains largely unknown. The in vitro studies and animal experiments revealed that sUA can enhance the antioxidant capacity of neurons and delay neurodegeneration and apoptosis. This paper mainly reviews the progress in epidemiological and basic studies of the relationship between sUA and neurodegenerative diseases in recent years, and aims to provide a reference for future novel prevention and treatment strategies for neurodegenerative diseases.
