| 摘要: |
| 基于动物模型及代谢组学方法,探讨玄参总苷的主要化学成分及其干预大鼠甲亢阴虚火旺证模型的作用机制。将SD大鼠随机分为对照组、模型组、玄参总苷给药组,腹腔注射3′,5-三碘代-L-甲状腺原氨酸(T3)溶液(100 μg/100 g)建立阴虚火旺模型,进行cAMP、cGMP水平等相关指标的检测,采用超高效液相色谱-四极杆-飞行时间串联质谱技术(ultra performance liquid chromatography-quadrupole-time of flight mass spectrometry,UPLC-Q-TOF-MS)对玄参总苷的化学成分和不同组别大鼠的血清内源性代谢物分析,并结合主成分分析(PCA)和正交偏最小二乘判别分析(OPLS-DA)多元统计分析,筛选差异性代谢物并构建其代谢通路。从玄参总苷中共鉴定了31个化学成分,玄参总苷能显著降低阴虚大鼠cAMP、cAMP/cGMP水平,阴虚火旺模型大鼠血清中25个内源性代谢物发生显著变化,其中鞘脂、类固醇、脂质、亚油酸、花生四烯酸呈上升趋势,通路分析表明玄参总苷可能通过调节鞘脂类、甘油磷脂、花生四烯酸等代谢途径改善阴虚火旺症候。本研究运用血清代谢组学方法揭示了玄参总苷干预甲亢阴虚火旺证的作用机制, 为玄参“滋阴降火”功效的物质基础和临床应用提供了理论依据。 |
