肠炎清Ⅰ号合锡类散保留灌肠治疗湿热内蕴型溃疡性结肠炎15例

目的 观察肠炎清Ⅰ号保留灌肠治疗湿热内蕴型溃疡性结肠炎（ulcerative colitis, UC）的临床疗效及其对血清IL-8和IL-4影响。方法 将30例湿热内蕴型UC患者,随机分为治疗组与对照组,每组各15例,治疗组用肠炎清Ⅰ号加锡类散0.75 g,常规保留灌肠。对照组用锡类散0.75 g,保留灌肠。两组患者均每日口服奥沙拉秦3 g。临床观察两组治疗前后疾病活动指数（disease activity index, DAI）、电子结肠镜下黏膜病理变化、血清白介素8（interleukin8, IL8）和白介素4（interleukin4, IL4）含量变化。结果 治疗后治疗组DAI显著低于对照组（P<0.01）;电子结肠镜显示治疗组黏膜炎症的改善程度显著优于对照组（P<0.05）;治疗组血清IL-8水平的下降和IL-4水平的升高显著优于对照组（P<0.05,或P<0.01）。结论 肠炎清Ⅰ号合锡类散灌肠治疗UC疗效显著,下调IL-8水平和升高IL-4水平可能是其治疗UC的作用机制之一。
