目的 观察健脾益肠散对溃疡性结肠炎(ulcerative colitis,UC)大鼠CD86分子(CD86)和细胞间黏附分子-1(intercellular adhesion molecule-1,ICAM-1)表达的影响,探讨其对UC肠黏膜的免疫保护机制。方法 将60只SD大鼠先随机分为空白组和造模组,造模组采用2,4,6-三硝基苯磺酸(2,4,6-trinitrobenzene sulfonic acid,TNBS)溶液灌肠法制备UC大鼠模型,待模型复制成功后再将造模组随机分为模型组、西药组和中药高、中、低剂量组;干预21 d后,免疫组化法检测各组大鼠结肠组织中CD86的阳性表达,Western Blot、RT-PCR法分别检测结肠中ICAM-1的蛋白和mRNA表达。结果 与空白组比较,模型组大鼠结肠组织中CD86的阳性表达以及ICAM-1的蛋白和mRNA表达均显著增高(P<0.01);与模型组比较,中药高、中、低剂量组和西药组CD86、ICAM-1的表达均不同程度地降低(P<0.05或P<0.01),且以中药高剂量组最为明显(P<0.05或P<0.01)。结论 健脾益肠散可能通过降低结肠组织中CD86、ICAM-1的表达水平起到对UC结肠黏膜的免疫保护作用。 |

Abstract: |
Objective To observe the effects of Jianpi Yichang Powder (JYP) on the expressions of CD86 molecule (CD86) and intercellular adhesion molecule-1 (ICAM-1) in ulcerative colitis (UC) rats, and to explore its immunoprotective mechanism of UC intestinal mucosa. Methods A total of 60 SD rats were randomly divided into a blank group and a modeling group. The UC models were established by the method of 2,4,6-trinitrobenzene sulfonic acid (TNBS) solution clyster. Then the successfully modeled rats were randomly divided into a model group, a western medicine group, a high, middle, and low dosage groups of Chinese herbal medicine. After intragastric administration for 21 days, immunohistochemical method was used to detect the positive expression of CD86. Western Blot and Real-Time PCR methods were used to detect the expression of ICAM-1 protein and mRNA in colonic tissue of rats in each group. Results The positive expression of CD86 and the protein and mRNA expressions of ICAM-1 in colonic tissue of the model group were significantly increased than those in the blank group (P<0.01). The expressions of CD86 and ICAM-1 in high, middle, low dose groups of Chinese herbal medicine groups and western medicine groups were decreased than the model group in different degrees (P<0.05 or P<0.01), and the high dose group of Chinese herbal medicine was the most obvious (P<0.05 or P<0.01). Conclusion JYP may play an immune protective role on colon mucosa of UC by decreasing the expression of CD86, ICAM-1 in colon tissue. |
