摘要：目的观察四神丸对溃疡性结肠炎(UC)大鼠结肠黏膜细胞间黏附分子-1(ICAM-1)mRNA和蛋白表达的影响,并探讨其作用机制。方法 40只SPF级Wistar大鼠随机分为空白组、模型组、四神丸组及柳氨磺吡啶(SASP)组,除空白组外,其余各组大鼠均以TNBS/乙醇灌肠法制备UC大鼠模型,四神丸组给予四神丸浸膏剂5 g/kg灌胃,SASP组SASP 0.3 g/kg灌胃,灌胃体积均为10 mL/kg,空白组、模型组灌服等体积生理盐水,持续3周。肉眼观察结肠大体形态损伤并进行评分,采用RT-PCR和免疫组化法检测ICAM-1基因和蛋白表达水平。结果与空白组比较,模型组大鼠结肠组织黏膜层肉眼观察可见炎症和溃疡形成。模型组大鼠结肠组织ICAM-1基因和蛋白的表达量上调(P<0.01);与模型组比较,四神丸组ICAM-1基因和蛋白表达量下调,差异有统计学意义(P<0.05,P<0.01)。结论四神丸可能通过下调ICAM-1 mRNA和ICAM-1蛋白的表达量,抑制炎症细胞浸润,阻止并减轻结肠组织损伤,起到治疗UC的作用。
Objective To observe the effect of Sishen Pill on ICAM-1 mRNA and protein expression of colonic mucosa in rats with ulcerative colitis （UC）, and identify its mechanism. Methods Taolly 40 SPF Wistar rats were randomly divided into blank group, model group, Pill group and SASP group. Except the blank group, UC model was prepared with TNBS/ethanol enema. Pill group was given Sishen Pill 5 g/kg, and SASP group was given SASP 0.3 g/kg by gavage, blank group and model group was given the same volume physiological saline for three weeks. Morphological injury of colonic mucosa was observed and scored. ICAM-1 gene and protein expression were detected by RT-PCR and immunohistochemical method. Results Inflammation and ulceration were found on the colonic mucous membrane of rats in the model group. The expression of ICAM-1 gene and protein of colonic tissues of rats in the model group increased compared with that of the blank group （P〈0.01）. Compared with the model group, the expression of ICAM-1 in Pill group decreased （P〈0.05, P〈0.01）. Conclusion Sishen Pill can decrease the expression of ICAM-1 mRNA and ICAM-1 protein, inhibit the infiltration of inflammation cells, prevent and reduce colon tissue damage, and play a vital role in the treatment of UC.
