Mass spectrometry assessment of the protective effects of Zhizi Dahuang decoction on alcoholic liver injury

  • 摘要: 采用液体辅助表面解吸常压化学电离质谱(LA-DAPCI-MS)技术对正常大鼠肝脏(正常组)、急性酒精性肝损伤大鼠肝脏(模型组)和接受栀子大黄汤治疗的肝损伤大鼠肝脏(治疗组)3组切片进行质谱成像研究,结合主成分分析(PCA)法对3组大鼠肝脏进行区分,识别出不同组动物肝内的差异性磷酸胆碱PC(34∶2),PC(36∶4)和PC(38∶4)。成像结果显示,在0.01 mm2的空间分辨率下,3种磷酸胆碱在肝组织中分布较均匀,在模型组中的含量相较于正常组和治疗组均降低,揭示了急性酒精性肝损伤与肝内磷脂变化的关系,在分子水平上评价了栀子大黄汤对急性酒精性肝损伤引起的肝内磷脂变化的保护作用。
    Abstract: Liquid-assisted surface desorption atmospheric pressure chemical ionization mass spectrometry(LA-DAPCI-MS)was used directly for the analysis of healthy rat liver(normal control group), acute alcoholic injury rat liver(alcohol model group)and Zhizi Dahuang decoction-treated rat liver(ZZDHD group)sections with the mass spectrometry images obtained simultaneously. Principal component analysis(PCA)was employed for the differentiation of livers of the groups, and 3 phospholipids, PC(34 ∶2), PC(36 ∶4)and PC(38 ∶4), were found to be the main factors. LA-DAPCI mass spectrometry images showed that the 3 phospholipids were evenly distributed in liver under the spatial resolution of 0. 01 mm2. Contents of 3 PCs in the model group were decreased in alcohol model group compared to the normal control group and the ZZDHD group, which revealed the relationship between acute alcoholic liver injury and intrahepatic phospholipid variation. The results showed that ZZDHD had protective effect on acute alcoholic liver injury-induced intrahepatic phospholipid variations at the molecular level.
