Abstract:
OBJECTIVE:To explore the metabolic characteristics and metabolic markers of WBC-depleted RBCs in MAP preservation solution and to analyzed the metabolic profile of RBC in MAP preservation solution by using metabolomics.
METHODS:The changes of metabolitcs in 10 U WBC-depleted RBC suspension at 3-different storage period (D 0, D 14 and D 35) were detected by using the UPLC-MS/MS, the charaeteristic ions and metabolic markers of RBC stored in preservation sblution for 0 d, 14 d and 35 days were analyzed by using the principal component analysis(PCA).
RESULTS:The number of characteristic ions in RBC and supernatant extracts detected during the initial, middle and final storage could be clearly distinguiseed. The 5 metabolism-related substamces such as lact-c acid, nicotinamide, glucose, 5-htdroxyproline and malic acid showed statistically significant difference in 3 storage period.
CONCLUSION:The UPLC-MS/MS method combined with statistical analysis of multivariate data can be used to study the metabolic characteristics of RBC, the different metabolites of RBC in different storage stages can be used as the potential markers for evaluation of guality of RBC in storag period. The results of this study provide a basis for studing the RBC guality changes in storage period.
