[Nontargeted lipidomic analysis of sera from sepsis patients based on ultra-high performance liquid chromatography-mass spectrometry/mass spectrometry].

There are significant differences in lipid metabolites between the sera of sepsis patients and healthy volunteers. PE (18:0p/20:4), PC (16:0/16:0) and LPC (18:1) may be new targets for sepsis prediction and intervention.
