Clinical data, fresh feces and intestinal mucosal tissues of patients with diarrheal IBS were collected. High performance liquid chromatography, immunohistochemistry and immunofluorescence were used to study the amino acid levels in feces of patients with IBS, the expression of taste receptors in intestinal mucosa, and the correlation between symptoms of abdominal pain and diarrhea and the expression of taste receptors, so as to obtain the conclusion that "intestinal amino acid perception abnormalities exist in patients with IBS. And correlated with clinical symptoms."
