摘要: 目的:探究水溶性蜂胶对酒精加重溃疡性结肠炎(UC)发作时结肠炎症的缓解作用并对其作用机制进行初步探讨。方法:SPF级雄性SD大鼠 40 只,随机分为对照组、UC组、UC+酒精组、UC+酒精+蜂胶组和UC+酒精+美沙拉嗪组。除对照组外,其余各组均通过自由饮用葡聚糖硫酸钠(DSS)建立UC疾病模型。对各组大鼠进行疾病活动指数(DAI)评分、组织学评分(HS)、结肠长度测量、结肠质量测量,酶联免疫吸附测定检测结肠组织中促炎细胞因子白细胞介素-6、白细胞介素-17,肿瘤坏死因子-?琢和抗炎细胞因子白细胞介素-10 的水平。结果:DSS成功建立UC大鼠模型。与UC组比较,UC+酒精组大鼠结肠损伤程度增强,HS显著升高(P<0.01),促炎细胞因子水平均显著增高(P<0.01),抗炎细胞因子水平明显降低(P<0.01);与UC+酒精组比较,UC+酒精+蜂胶组和UC+酒精+美沙拉嗪组大鼠结肠损伤程度改善,HS降低(P<0.05),促炎细胞因子水平减少、抗炎细胞因子水平升高(P<0.01)。结论:酒精加重UC的发作,水溶性蜂胶可以通过降低结肠组织中促炎细胞因子水平,提高抗炎细胞因子水平,从而缓解酒精加重的UC发作,减轻结肠炎症。

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.
