目的 从炎症反应和肠道屏障两个方面探究五味苦参肠溶胶囊对葡聚糖硫酸钠(DSS)诱导的小鼠结肠炎的治疗作用。方法 6~8周龄雄性BALB/c小鼠被随机分为3组,分别为正常组、急性肠炎模型组和五味苦参组。急性肠炎模型组和五味苦参组小鼠予含有3% DSS的饮用水1周诱导急性结肠炎,其后急性肠炎模型组予PBS灌肠,五味苦参组予五味苦参肠溶胶囊制备为灌肠液灌肠。每天称量小鼠体质量,观察大便性状及血便情况,第8天处死小鼠,取结肠组织检测炎症细胞因子和肠屏障因子。结果 与正常组相比,急性肠炎模型组肠道炎症明显,五味苦参组有效缓解肠道炎症和有利于肠上皮屏障修复。表现为五味苦参灌肠液有效缓解小鼠体质量下降,具有较低的DAI评分,有较好的组织学表现,其结肠组织IL-1β,IL-6和TNF-α的相对表达下降,Occludin和ZO-1的相对表达增加(P<0.05)。结论 五味苦参肠溶胶囊制备的灌肠液可减轻DSS诱导的小鼠急性结肠炎。
Objective To explore the therapeutic effect of five-flavor sophora flavescens enteric-coated capsules(FSEC)on dextran sulphate sodium(DSS)-induced colitis in mice from inflammatory response and intestinal barrier.Methods Male BALB/c mice aged 6-8 weeks were randomly divided into three groups,namely normal group,acute colitis group and FSEC group.The mice in acute colitis group and FSEC group were given drinking water containing 3% DSS for one week to induce acute colitis,and then they were given PBS enema or FSEC enema respectively.The mice were administered daily,including weight loss,the stool properties and bloody feces.The mice were sacrificed on the 8th day,and the colon tissue was collected to detect inflammatory cytokines and intestinal barrier cytokines.Results Compared with the normal group,the intestinal inflammation in the acute colitis group was obvious,however the FSEC effectively relieved intestinal inflammation and facilitated the intestinal epithelial barrier repair.It showed that FSEC enema effectively relieved weight loss and had a lower disease activity index score.In addition,FSEC enema group had better histological appearance.Compared to acute colitis group,the relative expression of IL-1β,IL-6 and TNF-α in colon tissue decreased,and the relative expression of Occludin and ZO-1 significantly increased in FSEC group(P<0.05).Conclusions FSEC enema can alleviate DSS-induced acute colitis in mice.
