探讨溃疡性结肠炎的发病原因，探索中医方剂仙翁愈疡合剂治疗溃疡性结肠炎的疗效及机制。

选取2013年10月至2014年3月来自聊城市人民医院肛肠科住院的经中医辨证为大肠湿热型溃疡性结肠炎患者60例，所有病例均进行纤维结肠镜检查，随机分为治疗组和对照组，每组30例。分别给予仙翁愈疡合剂50 ml和锡类散2 g＋0.9%生理盐水50 ml，每晚睡前1次保留灌肠，疗程20天。比较两组治疗前后症状改善情况及证候积分。

临床症状缓解情况，治疗组腹痛、腹泻、黏液血便及里急后重症状改善明显优于对照组（u=2.44，2.77，2.52，2.40，P<0.05），两组中医证候积分比较，组内治疗前后比较均有效（t=7.645，t=4.295，P<0.05），治疗后两组之间比较治疗组证候积分的改善明显优于对照组（t=2.942，P<0.05）。

溃疡性结肠炎发病原因为脾胃虚弱为本，大肠湿热为标，气滞血瘀贯穿整个病程，湿、热、瘀、虚是溃疡性结肠炎发病的重要机制。仙翁愈疡合剂治疗早中期溃疡性结肠炎安全有效。
