The invention discloses a molecular marker for diagnosing an inflammatory bowel disease and application of the molecular marker, and the molecular marker for diagnosing the inflammatory bowel disease (IBD) is ribonuclease III (Ribonuclease III, RNASE3). The expression level of the RNASE3 protein in the colon of a mouse with DSS induced colitis is obviously higher than that of a control mouse, and the expression level is further confirmed in the colon of a clinical IBD patient. The method has the advantages that the expression quantity of the RNASE3 protein in the excrement of the mouse in the acute stage is the highest, and the expression quantity of the RNASE3 protein in the remission stage is reduced, so that the research finds that the RNASE3 is a potential biomarker of the IBD and has the characteristics of noninvasive property, sensitivity and the like.

The invention provides an application of IL-28A in preparation of a medicine for treating colon cancer/colitis, and belongs to the technical field of biological medicine.In an AOM + DSS model, compared with a wild type mouse (IL-28AWT) group, colon tumors of IL-28A gene knockout (IL-28A-/-) mice grow more quickly, the number of the tumors is larger, and the colon cancer/colitis can be better treated. Meanwhile, whether the IL-28A has an inhibiting effect on the development of mouse colitis diseases or not is also researched, and the result shows that the IL-28A can inhibit acute enteritis of mice. Furthermore, the invention finds that IL-28A directly inhibits differentiation and recruitment of MDSCs by activating an IL-28A receptor expressed by MDSCs, and plays a key regulation role in occurrence and development of colon cancer. Therefore, the invention reveals that IL-28A can significantly inhibit colon cancer/colitis for the first time. The invention provides a new drug choice for clinical diagnosis and treatment of tumors.

The present invention provides use of an ldh gene-containing lactobacillus plantarum in preparing a product for relieving enteritis. The lactobacillus plantarum or plasmid involved in the present invention is an ldh gene-containing lactobacillus plantarum or plasmid. Experiments prove that the ldh gene has the function of preventing and relieving inflammation. According to the present invention, lactobacillus plantarum AR113 with acetate kinase (ackA), D-lactate dehydrogenase (D-ldh), and L-lactate dehydrogenase (L-ldh) knocked out is taken as a research object. By studying the effect of the knock-out strains on O157:H7-induced colitis, the important role of lactic acid in alleviating tissue damage caused by O157:H7 and protecting the integrity of intestinal epithelial cells is investigated, and lactic acid can effectively relive and prevent different types of enteritis; a lactic acid or a lactate dehydrogenase gene is selected as a screening marker for bacterium screening, and it is concluded that it is the lactic acid that plays a major relieving role in colitis, thereby laying a foundation for a method for screening probiotics with an inflammation relieving function.

Irritable Bowel Syndrome (IBS) is a multifactorial disorder characterized by pain, bloat, and changes in bowel movements, where different bacteria in the gut microbiome potentially influence some or all of the related symptoms. However, IBS is extremely heterogenous, suggesting a need to identify relationships between groups of bacteria in the gut microbiome and specific IBS-related symptoms. RS consumption significantly altered the microbiome while improving several measures of IBS. The use of RS by those needing to reduce the IBS-related symptoms, including those diagnosed with IBS, can be guided by simultaneously measuring changes in select genera in the microbiome.
