应用液相色谱-串联质谱技术(liquid

tandem
spectrometry,LC-MS/MS)和代谢组学方法探讨早产儿视网膜病(retinopathy
prematurity,ROP)患儿出生血代谢产物差异,寻找ROP早期诊断的新的生物标记物。方法:
收集2013年1月—2016年12月中山大学附属第六医院住院的21例ROP患儿(ROP组)及同期21例非ROP患儿(非ROP组)干血片标本,利用LC-MS/MS进行代谢产物测定,运用正交偏最小二乘判别分析法(orthogonal
squares
discriminant
analysis,OPLS-DA)寻找差异物质和生物标记物。结果:
ROP组和非ROP组患儿血代谢谱有明显差异,经模式识别分析、代谢物得分图(Score-plot,S-plot)、权重分析初步得出10个差异较大的氨基酸。进一步统计分析发现ROP组患儿血谷氨酸、亮氨酸、天冬氨酸、鸟氨酸和甘氨酸水平明显高于非ROP组,差异有统计学意义(P<0.05)。受试者工作特征曲线分析显示,谷氨酸及鸟氨酸对ROP诊断价值最高。结论:
ROP患儿与非ROP患儿比较血代谢产物具有明显差异,谷氨酸及鸟氨酸是诊断ROP的代谢标志物。LC-MS/MS结合代谢组学分析方法在ROP早期识别与诊断中具有潜在的应用价值。.
