Study design:

Cross-sectional 

研究目的:

1) 探讨IBD患者粪便中A.muciniphila丰度与外周血GPR15表达水平之间的关系; 2) 研究IBD患者粪便中A.muciniphila丰度与结肠组织中GPR15表达水平之间的关系; 3) 明确A.muciniphila在不同疾病活动度IBD患者粪便中的丰度; 4) 探索A.muciniphila丰度与不同亚型IBD患者的关系; 5) 明确A.muciniphila在健康对照者和IBD患者粪便中的丰度差异。  

Objectives of Study:

1) Explore the association between fecal A.muciniphila levels and peripheral blood GPR15 levels in patients with IBD; 2) Explore the association between fecal A.muciniphila levels and colonic GPR15 levels in patients with IBD; 3) Identify the abundance of fecal A.muciniphila in IBD patients with different disease activity; 4) Explore the association between fecal A.muciniphila levels and disease subtypes in patients with IBD; 5) Explore the differences in fecal A.muciniphila levels between IBD patients and healthy controls.
