Objective: To explore the difference of intestinal flora between groups of ulcerative colitis and large intestine dampness heat syndrome and healthy group. Methods: A total of 14 stool samples from patients with ulcerative colitis and large intestine dyspepsia syndrome and 14 samples of healthy people were collected. Amplification was designed based on the 16 S r DNA V3-V4 region of the bacteria. Illumina HiSeq 2500 platform was used for high-throughput sequencing.The ultimately sample species information was get by Reads splicing, OTUs (operational taxonomic units) clustering, species annotation, the analysis of alpha diversity and the analysis of principal component. Results: There was a significant difference in intestinal flora between the ulcerative colitis group and the healthy group (P=0.008 < 0.01); and the diversity of intestinal flora in patients with ulcerative colitis and large intestine dyspepsia syndrome was higher than that of healthy people. There a significant difference in the richness degree of intestinal flora patients with ulcerative colitis and large intestine dampness syndrome and the healthy group. Intestinal flora centered on Lactobacillus、Lactobacillaceae、Erysipelotrichaceae、Erysipelotrichales and Akkermansia bacteria was rich in patients with ulcerative colitis. Conclusion: There are significant differences in intestinal flora diversity and bacterial structure between patients with ulcerative colitis and large intestine dampness syndrome and the healthy group.

This paper was aimed to study the effect of Qing-Chang Wen-Zhong (QCWZ) decoction on interferon gamma induced protein 10 (IP10) in colon tissues of rats with ulcerative colitis (UC).The UC model was induced using 4.5% DSS added to distilled water for 7 days.At the same time,low-,medium-and high-dose of QCWZ decoction and mesalazine was given by gavage route daily.Then,the rats were killed and the colon tissues were taken.Expression level of interleukin-1 alpha (IL-1α),IL-1β,IL-6,tumor necrosis factor alpha (TNF-α) and interferon gamma (INF-γ) in colon were detected by Elisa assay.The expression and distribution of IP10 protein were detected by immunohistochemistry (IHC).The results showed that compared with the normal group,inflammatory factors (IL-1α,IL-1β,IL-6,TNF-α,INF-γ) and IP10 expression level in DSS-induced UC rats were significantly increased.After 7 days of intervention,inflammatory factors (IL-1α,IL-1β,IL-6,TNF-α,INF-γ) and IP10 decreased significantly (p<0.01,p<0.05).It was concluded that QCWZ decoction may down-regulate the expression of IP 10 and inflammatory factors (IL-1α,IL-1β,IL-6,TNF-α,INF-γ),and then inhibit intestinal inflammation and repair intestinal mucosal damage,so as to achieve the purpose of UC treatment.
