摘要:
目的 探讨艾黄素(artemitin)对臭氧暴露诱发的小鼠肺部炎症是否具有保护作用及其潜在机制。 方法 将32只雄性SPF级C57BL/6小鼠随机分为空白对照组、艾黄素对照组、模型组、艾黄素治疗组,每组8只。艾黄素治疗组每日先腹腔注射艾黄素(20 mg/kg),再持续吸入0.000 25%臭氧1 h;艾黄素对照组每日先腹腔注射艾黄素(20 mg/kg),再吸入洁净空气;模型组每日先腹腔注射等体积生理盐水,再吸入0.000 25%臭氧1 h;空白对照组每日先注射等体积生理盐水,再吸入洁净空气;以上各组均连续处理7 d。采用全身体积描记检测系统检测各组小鼠的肺功能指标;采用ELISA检测支气管肺泡灌洗液中肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)、白细胞介素-1β(interleukin-1β,IL-1β)水平;采用HE染色观察肺组织病理学变化;并采用超高效液相色谱质谱联用对血浆中整体代谢通路的变化进行非靶向代谢组学分析。 结果 与模型组相比,艾黄素治疗能显著改善臭氧引起的肺功能损伤(P<0.05)、降低支气管肺泡灌洗液中TNF-α、IL-1β的蛋白水平(P<0.05)、减轻肺组织炎症细胞浸润和结构破坏。代谢组学结果提示,艾黄素治疗可代偿性增强能量供给和氧化脂质信号,抑制嘌呤代谢与色氨酸衍生通路。 结论 艾黄素对臭氧暴露诱发的小鼠肺部炎症具有明显的保护作用,其通过协同调控色氨酸代谢、能量代谢和脂质炎症介质,从代谢层面改善代谢紊乱,进而抑制下游炎症反应与气道高反应性。本研究不仅揭示了艾黄素治疗气道炎症的多效性机制,还为其临床转化提供了潜在的代谢生物标志物和理论依据。
