摘要(Abstract):
目的观察艾灸及艾烟对载脂蛋白E基因敲除(ApoE-/-)小鼠肺组织病理及血清白细胞介素-4(IL-4)、干扰素-γ(IFN-γ)的影响,评价艾灸及艾烟的安全性,并探讨艾灸在动脉粥样硬化炎症反应过程中的起效机制。方法 30只8周龄雄性采用高脂饮食喂养的载脂蛋白E基因敲除(ApoE-/-)小鼠随机分为3组(每组10只):模型组、艾灸组、艾烟组。10只同周龄雄性普通饲料喂养的C57BL/6非转基因小鼠作为空白对照。空白组和模型组小鼠均采用固定器固定,每日抓取固定20 min;艾灸组采用固定器固定小鼠,在膻中施灸20 min,艾烟组采用固定器固定小鼠后,将固定器放入5~15 mg/m3的艾烟环境中20 min,各组每周均干预6 d,连续干预14周后取材,观察小鼠的一般情况和肺组织病理及血清IL-4、IFN-γ水平。结果肺组织病理切片显示,空白组、模型组、艾灸组和艾烟组肺组织结构完整清晰;模型组小鼠血清中IL-4含量最低,IFN-γ含量最高,与空白组比较,差异有统计学意义(P <0.05);与模型组比较,艾灸组和艾烟组小鼠血清中IL-4水平含量均显著升高(P <0.05),IFN-γ水平含量均显著降低(P <0.05)。结论艾灸及艾烟对小鼠肺组织病理变化无影响;模型组ApoE-/-小鼠表现为动脉粥样硬化过程中的炎症反应,IL-4水平降低,IFN-γ水平升高;艾灸及艾烟能够提高IL-4水平,降低IFN-γ水平,可明显降低动脉粥样硬化过程中的炎性反应。
