目的 研究芩百清肺浓缩丸治疗支原体肺炎的作用机制。方法 采用超高效液相色谱与串联四级杆飞行时间质谱（UPLC-Q-TOF-MS）联用技术的代谢组学方法，分析肺炎支原体感染小鼠肺组织中内源性化合物的变化。采用Progenisis QI软件进行色谱峰识别及匹配，并采用主成分分析（PCA）和偏最小二乘-判别分析（PLS-DA）对获得数据进行降维，通过分析对不同组间分离贡献度较大（VIP > 1，P < 0.05）化合物的串联质谱数据，经HMDB等数据库检索，确定潜在生物标志物。结果 从肺组织中共鉴定出视黄醛、全反式维甲酸、焦谷氨酸、白三烯C4、维生素A、花生四烯酸、前列腺素I2等20个潜在生物标志物。与模型组比较，芩百清肺浓缩丸对20个潜在生物标志物均具有回调作用。结论 芩百清肺浓缩丸通过影响视黄醇代谢、亚油酸代谢、花生四烯酸代谢等通路发挥治疗支原体肺炎的作用。

Objective To study the mechanism of Qinbai Qingfei Concentrated Pellets (QQCP) in the treatment of mycoplasma pneumonia pneumonia. Methods UPLC-Q-TOF-MS was applied to detect the change of endogenous substances in the lung tissue of mycoplasma pneumonia mice model after taking decoction of QQCP orally. Progenisis QI was adopted to identify and match the peak, and principal compoment analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were used to reduce data dimension. Through the analysis of tandem mass spectrum data of compound that had larger contribution to the separation among different groups (VIP > 1, P < 0.05) and the HMDB database retrieval to identify potential biomarkers. Results Twenty potential biomarkers were identified from lung tissue as retinal, all-trans-retinoic acid, pyroglutamic acid, leukotriene C4, vitamin A, arachidonic acid, and prostaglandin I2. Compared with model group, QQCP group had callback function of 20 potential biomarkers. Conclusion QQCP play a role of treatment for mycoplasma pneumonia by affecting retinol metabolism, linoleic acid, and arachidonic acid metabolism. These results indicated that QQCP had the characteristics of multi-pathway, multi-target and overall regulation in the treatment of mycoplasmal pneumoniae pneumonia.
