Abstract:
Objective To evaluate the quality of blood after marine storage and transportation,to establish a quantitative energy metabolism platform supported by extracellular flux(XF)technique to determine the glycolysis level of red blood cells(RBC), and to introduce the "functional dose", as a valuable supplement, into the quality evaluation of RBCs after marine storage and transportation.Methods The extracellular acidification rate(ECAR)of erythrocyte glycolysis was detected by XF.The levels of glycolysis, ATP contents and free hemoglobin of RBCs were detected before and after marine navigation.RBC suspensions stored at 4℃in a blood bank on land served as control.Results The results showed that the glycolysis level of RBCs was detected by XF.Indicators of blood quality and energy metabolism of RBCs were detected in the twice marine storage and transportation.Blood samples transported around the Gulf of Bohai had no significant change,indicating that the samples were well preserved.The energy indicators of blood samples navigated in the Pacific Ocean decreased significantly,and it was recommended that the samples be discarded.Conclusion XF technique has been applied to the measurement of erythrocyte glycolysis,enabling high-throughput and multi-indicator dynamic detection of viable cells.The energy metabolism of erythrocyte should be recommended as an important indicator for evaluating blood after marine storage and transportation.
