肠道微生物-肠-脑轴与卒中后认知障碍的相关性研究进展

Research progress on the relation between gut microbiome-gut-brain axis and post-stroke cognitive impairment

卒中后认知障碍(PSCI)是卒中后常见的功能障碍,严重影响患者的生活质量和正常功能。研究显示肠道微生物群失调与中枢神经系统疾病关系密切,肠道菌群通过调节肠-脑轴可维持神经、代谢和免疫系统的稳定性,对人类生理健康产生多方面的影响。众多研究发现,肠道微生物-肠-脑轴在卒中及相关PSCI的发生和发展中发挥重要作用,调节肠道微生物-肠-脑轴有望成为PSCI治疗的潜在靶标。本文对肠道微生物-肠-脑轴与PSCI的相关性研究进展进行综述,以期为相关的机制探索和临床防治提供参考。

Post-stroke cognitive impairment(PSCI) is a prevalent functional impairments following stroke that seriously affects patients' quality of life and daily activities.Studies indicate a close relationship between intestinal microflora dysbiosis and central nervous system diseases.Intestinal microflora profoundly impacts on human physiological health,contributing to the stability of nervous,metabolic and immune systems through regulation of the gut-brain axis.An increasing number of studies confirmed the important role of the gut microbiome-gut-brain axis in the occurrence and development of stroke and its associated PSCI,and regulation of microbiome-gut-brain could be potential target to treatment of PSCI.This review summarizes research progress on gut microbiome-gut-brain axis and PSCI to provide a reference for exploration of related mechanisms and clinical prevention and treatment strategies.
