3、持尾静脉注射。2周后使用多导生理记录仪15T（PowerLab 15T）数据采集与分析系统记录肢体导联心电图，监测各组大鼠房颤的持续时间；采用苏木精-伊红（HE）染色观察大鼠心房肌组织病理形态表现；酶联免疫吸附法（ELISA）检测大鼠血清中TNF-、ICAM-1的表达水平。结果（1）HE染色结果显示，空白组大鼠心房肌组织染色均匀，细胞形态正常；模型组大鼠心房肌细胞肿胀，纤维组织排列紊乱、断裂；与模型组相比，中药复方高剂量组、中药复方中剂量组及维拉帕米组鼠心房肌细胞肿胀改善，心房肌纤维排列相对整齐。（2）与空白组相比，模型组大鼠血清中TNF-和ICAM-1水平升高（P0.01）。与模型组相比，中
4、药复方高剂量组、中药复方中剂量组、中药复方低剂量组和维拉帕米组大鼠血清中TNF-水平降低（P0.05或P0.01）；中药复方高剂量组、中药复方中剂量组和维拉帕米组ICAM-1水平降低（P0.05 or P0.01）。结论 中药复方可以降低血清中TNF-和ICAM1水平，抑制炎症因子的过度表达，减轻心脏炎症活动度，改善心房肌组织损伤，从而发挥对心房颤动的治疗作用。关键词：心房颤动；中药复方；炎症反应；肿瘤坏死因子；细胞间黏附分子中图分类号：R541.75 文献标志码：A 文章编号：1673-842X (2023)01-0025-05Effects of Traditional Chinese M
