研究目的:

本项目拟从“微生物-肠-脑轴”角度出发,利用多模态 MRI技术联合微生物组学分析,重点阐述FCon患者肠道菌群多样性和物种相对丰度的异常改变与患者脑结构、功能、连接损害的关系,并进一步探讨FCon患者脑损害与肠道菌群紊乱和精神障碍类疾病是否存在中介关系。提出了FCon患者肠道菌群紊乱可引起脑结构、功能、连接的损害,进而导致FCon发生及其伴随的精神障碍类疾病发生、发展这一科学假设。本项目有助于从 “微生物-肠-脑轴”角度理解FCon发生、发展的神经机制,进而为以肠道菌群作为干预靶点治疗FCon以及相关药物研发提供理论基础的研发提供理论基础。  

Objectives of Study:

In this project, we aim to elucidate the relationship between abnormal alterations in the diversity and relative abundance of species in the gut microbiota of patients with fcon and the impairment of brain structure, function, connectivity, using multimodal MRI combined with microbiome analysis from the perspective of the "" microbiome gut brain axis "", and to further explore whether there is a mediating relationship between brain damage and gut microbiota disturbance and psychiatric disorders in patients with fcon. It has been proposed that the disturbance of intestinal flora in fcon patients can cause damage to brain structure, function, connection, and then lead to the scientific hypothesis that fcon occurs and its concomitant psychiatric disorders like disorders. This project can contribute to the understanding of the neural mechanisms underlying the occurrence and development of fcon from the perspective of the "" microbiota gut brain axis "", and then provide a theoretical basis for the development of gut microbiota as an intervention target for the treatment of fcon as well as related drug discovery.
