Abstract: Objective: To explore the protective effect of water-soluble propolis on easing the ulcerative colitis(UC) aggravated by alcohol and to explore its mechanism. Methods: 40 SPF male SD rats were randomly divided into the control group, the UC group, the UC+alcohol group, the UC+alcohol+propolis group and the UC+alcohol+mesalazine group. Except for the control group, the UC disease models were established by drinking dextran sodium sulfate(DSS) freely in other groups. Disease activity index(DAI) score, histological score(HS), colon length measurement, colon quality measurement were performed on rats in each group, and the levels of the pro-inflammatory cytokines IL-6、 IL-17、TNF -?琢 and anti-inflammatory cytokine IL-10 in colon tissue were detected by ELISA. Results: UC rat model was successfully established by DSS. Compared with the UC group, the colon injury degree of the UC+alcohol group was enhanced, HS was significantly increased(P<0.01), the levels of pro-inflammatory cytokines were significantly increased(P<0.01),and the level of anti-inflammatory cytokine was significantly reduced(P<0.01); compared with the UC+alcohol group, the degree of colon injury in the UC+alcohol+propolis group and the UC+alcohol+mesalazine group were improved, HS was reduced(P<0.05), the levels of pro-inflammatory cytokines were reduced, and the level of anti-inflammatory cytokine was increased(P<0.01). Conclusion: Alcohol accelerates inflammatory responses in the gut and makes UC worse. Water-soluble propolis can reduce the level of pro-inflammatory cytokines in colon tissues, and increase the level of anti-inflammatory cytokines, thereby alleviating the injury of UC aggravated by alcohol and reducing the inflammation of the colon.
