虎杖苷对DSS和TNBS诱导的急性结肠炎的作用及机制的研究

虎杖苷对DSS和TNBS诱导的急性结肠炎的作用及机制的研究摘要：

目的：探讨虎杖苷对DSS和TNBS诱导的急性结肠炎的作用及其机制。

方法：将40只小鼠随机分为四组：正常组、模型组、虎杖苷高剂量组和虎杖苷低剂量组。模型组使用DSS和TNBS诱导急性结肠炎，虎杖苷高、低剂量组同时给予虎杖苷治疗。采用病理学方法和ELISA检测末段恢复期各组大鼠结肠组织病理学改变情况和白细胞介素-6（IL-6）、肿瘤坏死因子-α（TNF-α）等炎性因子水平。

结果：与模型组相比，虎杖苷低、高剂量组大鼠结肠组织病理学表现显著改善，炎性细胞浸润明显减少，并且虎杖苷高剂量组大鼠结肠组织病理学表现更佳。同时虎杖苷高、低剂量组IL-6、TNF-α水平明显下降，其中虎杖苷高剂量组下降更明显。

结论：虎杖苷具有显著的治疗DSS和TNBS诱导急性结肠炎作用，可能通过抑制炎性因子水平改善结肠组织病理学表现。

Introduction

急性结肠炎是一种以大肠为主要发病部位的肠黏膜炎症性疾病，主要表现为腹痛、腹泻、便血等症状。虽然目前已有多种药物治疗急性结肠炎，但是治疗效果具有一定局限性。近年来，有研究发现中药虎杖苷具有一定的抗炎作用，但其对急性结肠炎的作用和机制尚不明确。

Methods

40只BALB/C小鼠随机分为正常组、模型组、虎杖苷高剂量组和虎杖苷低剂量组。模型组使用DSS和TNBS给予大鼠诱导急性结肠炎，虎杖苷高、低剂量组给予虎杖苷治疗。采用病理学方法和ELISA检测末段恢复期各组大鼠结肠组织病理学改变情况和IL-6、TNF-α等炎性因子水平。

Results

与模型组相比，虎杖苷低、高剂量组大鼠结肠组织病理学表现显著改善，炎性细胞浸润明显减少，并且虎杖苷高剂量组大鼠结肠组织病理学表现更佳。同时虎杖苷高、低剂量组IL-6、TNF-α水平明显下降，其中虎杖苷高剂量组下降更明显。

Conclusion

虎杖苷具有显著的治疗DSS和TNBS诱导急性结肠炎作用，可能通过抑制炎性因子水平改善结肠组织病理学表现。上述结果提示，虎杖苷可能成为治疗急性结肠炎的潜在治疗药物。
