Abstract 目的 肝病变是溃疡性结肠炎(ulcerative colitis,UC)最常见的肠外表现,但其发生机制目前尚未完全阐明,目前普遍认为其发生与免疫激活、肠道菌易位肝、炎症因子风暴及胆汁酸循环紊乱有关。UC相关性肝疾病的发生使其临床治疗更为困难,探究UC肝损伤的发病机制对于UC相关性肝疾病的防治意义重大。谷胱甘肽(glutathione,GSH)具有清除自由基、参与肝解毒代谢及免疫防御等多种生理功能,GSH的合成及氧化还原能力共同决定GSH的抗氧化功能。肝GSH抗氧化功能缺陷与多种肝疾病的发生密切相关,但其是否参与并介导UC相关性肝损伤的发生目前尚不明晰。本研究旨在探究UC发生中GSH合成及还原功能变化特征及其分子机制。 方法 应用2,4,6-三硝基苯磺酸(2,4,6-trinitrobenzenesulfonic acid,TNBS)乙醇溶液(每只5 mg/0.8 mL,50%乙醇)灌注结肠制备UC大鼠模型,分别在TNBS灌注后第3、5和7天取材血清、肝及肠道组织,测定疾病活动指数、结肠组织髓过氧化物酶活性及结肠病理组织学评分以评价UC结肠的病变程度;以肝病理组织学评分、血清谷草转氨酶(AST)和谷丙转氨酶(ALT)水平为指标评估肝病变程度;并分别将UC造模7天组大鼠肝病理评分和血清AST水平与其结肠病变程度做Spearman相关分析以明确UC发生中肝病变与结肠病变的相关性。采用试剂盒动态测定UC造模后第3、5和7天组大鼠肝中GSH含量、GSH过氧化物酶(glutathione peroxidase,GSH-Px)及GSH还原酶(glutathione reductases,GR)活性;并应用蛋白质印迹法检测肝中GSH合成反应关键酶谷氨酰胺半胱氨酸连接酶(glutamine cysteine ligase,GCL)、GSH合成酶以及GSH-Px和GR蛋白质表达的变化。 结果 与正常对照组相比,UC造模后第3、5及7天组大鼠的疾病活动指数、结肠组织髓过氧化物酶活性及结肠病理组织学评分均显著高于正常对照组(均 P 15%为4分)及粪便形状评分(正常为0分,成形软便为2分,软便不成形为3分,腹泻为4分)为指标计算病变活动指数(disease activity index,DAI)。最后以DAI、结肠组织髓过氧化物酶(myeloperoxidase,MPO)活性及结肠病理组织学评分 [11] 为指标评估UC模型。本实验已获得兰州大学医学伦理委员会批准(审批号:LDYYLL2017-37)。 1.2.2
