Poststroke Depression of Clinical Trial Registration

First Affiliated Hospital Xi'an Jiaotong University100 enrolled

Overview

The investigators aim to explore the relationship between gut microbiota composition and earlier poststroke depression via 16S rRNA sequencing.

In this study, patients with first ever acute ischemic stroke were studied. According to the psychological assessment, patients were divided into two groups according to whether or not there was a PSD at the earlier stage of stroke. Clinical biological data and blood and feces samples were collected. Firstly, 16srDNA sequencing was used to study the difference in the composition and diversity of intestinal microbial communities in the two groups of patients. Then the two groups selected individual representative samples and conducted macro genome sequencing. At the same time, by analyzing the correlation between the intestinal flora and the clinical risk factors and neurotransmitters in early PSD patients, the key functional bacteria related to PSD were identified.
