摘要
Objective: To study the evaluation value of intestinal flora detection for intestinal mucosal inflammatory response and immune response in patients with ulcerative colitis. Methods: The patients who were diagnosed with ulcerative colitis in Zigong Fifth People's Hospital between March 2015 and February 2017 were selected as the UC group, and those who were diagnosed with colonic polyps were selected as the control group. Fresh excreta were collected to detect the number of intestinal flora, and the diseased intestinal mucosa tissue was collected to detect the expression of inflammatory response molecules and immune cell transcription factors. Results: enterococcus contents in intestinal tract and TLR4, NF-kB, TNF-α, HMGB-1, T-bet and RORC mRNA expression levels in intestinal mucosa of UC group were significantly higher than those of control group while bifidobacteria contents in intestinal tract and SOCS2, SOCS3, Foxp3 and GATA-3 mRNA expression levels were significantly lower than those of control group;TLR4, NF-kB, TNF-α, HMGB-1, T-bet and RORC mRNA expression levels in intestinal mucosa of UC patients with grade II and grade III flora disturbance were significantly higher than those of UC patients with normal flora and grade I flora disturbance while SOCS2, SOCS3, Foxp3 and GATA-3 mRNA expression levels were significantly lower than those of UC patients with normal flora and grade I flora disturbance;TLR4, NF-kB, TNF-α, HMGB-1, T-bet and RORC mRNA expression levels in intestinal mucosa of UC patients with grade III flora disturbance were significantly higher than those of UC patients with grade II flora disturbance while SOCS2, SOCS3, Foxp3 and GATA-3 mRNA expression levels were significantly lower than those of UC patients with grade II flora disturbance. Conclusion: The intestinal flora disturbance in patients with ulcerative colitis can result in inflammatory response activation and immune response disorder.
