In this study, the clinical data of patients with AIS were collected, 16s RNA was used to detect the composition and diversity of intestinal flora, and flow cytometry and mass spectrometry were used to detect intestinal flora-related metabolites in plasma,to explore the influence of gut microbiota and its metabolites on stroke prognosis.
In recent years, more and more studies have been conducted on the gut-brain axis, and gut microbes can affect the brain by regulating immune responses, metabolites, and neurotransmitters. The composition of gut microbiota may affect stroke prognosis, including focal neurological deficits, cognitive impairment, anxiety and depression, and fatigue. In this study, 16s RNA was used to detect the composition and diversity of intestinal flora, and flow cytometry and mass spectrometry were used to detect intestinal flora-related metabolites in plasma. The clinical data of patients were collected, including age, gender, and medical history, NIHSS, mRS, MMSE, Patient Health Questionnaire-9(PHQ9), Social Support Rating Scale(SSRS), laboratory and radiology results. The neurological recovery of the patients was assessed after 3 and 6 months, and the presence or absence of post-stroke depression(PSD) and post-stroke fatigue(PSF) was assessed by the Hamilton Depression Scale, the Fatigue Severity Scale(FSS) and the Multidimensional Fatigue Scale(MFS). To evaluate the relationship between gut microbiota and its metabolites and stroke prognosis.
