     [摘要] 目的：探讨清热通下中药在急性胆管炎治疗中对肠黏膜屏障保护和炎症调控的作用。方法：60只SD大鼠分为3组，每组20只。模型组(A组)制作急性胆管炎模型；治疗组(B组)制作急性胆管炎模型并喂清热通下中药治疗；假手术组(C组)仅剖腹后缝合。取血检测细胞因子、炎症介质、内毒素和细菌移位等指标。结果：A组白细胞介素6(interleukin6, IL6)、白细胞介素8(interleukin8, IL8)、肿瘤坏死因子α(tumor necrosis factorα, TNFα)、血清C反应蛋白(C reactive protein, CRP)和一氧化氮(nitric oxide, NO)明显高于B组和C组(P<0.01)，IL2则显著低于B组和C组(P<0.01)；A组的血清内毒素和肝、脾、肠系膜淋巴结细菌移位数显著高于B组和C组(P<0.01)。结论：具有清热通下作用的中药在治疗急性胆道感染中具有保护肠黏膜屏障、降低血清内毒素和调节机体炎症反应的作用。

    ABSTRACT Objective: To investigate the effects of antipyretic and purgative herbs on intestinal mucosal barrier and inflammatory response in the treatment of acute cholangitis. Methods: Sixty SD rats were randomly divided into group A (untreated group, acute cholangitis was induced, n=20), group B (treatment group, acute cholangitis was induced and treated with antipyretic and purgative herbs, n=20) and group C (sham operation group, n=20). At the third or fifth day after operation, the rats were sacrificed and sampled. The serum endotoxin, cytokines and inflammatory mediators were tested and the numbers of labeled bacteria in the liver, spleen and mesenteric lymph nodes translocated from the gut were assayed. Results: As compared with group A, the serum content of endotoxin, IL6, IL8, TNFα, CRP and NO was significantly lower and that of IL2 was significantly higher, and the translocated numbers of labeled bacteria from gut were reduced in both group B and group C(P<0.01). Conclusion: Antipyretic and purgative herbs can play therapeutic roles in the treatment of acute biliary tract infections, including the protection of intestinal mucosal barrier from bacterial translocation, reduction of serum endotoxin content and regulation of inflammatory response. ......
