英文摘要Objective: To establish a LC-MS/MS method for determining the concentration of platelet activating factor (PAF) in human plasma and to know the activity of lipoprotein-associated phospholipase A_2 (LP-PLA_2), an independent risk factor for coronary artery disease (CAD) in clinical practice. Methods: After addition of PAF, the plasma sample was incubated at 37 ℃ for 10 min, then immediately pretreated with methanol for deproteinization. The supernatant was separated with liquid chromatography and detected with tandem mass spectrometry. The LP-PLA_2activity was assessed from the velocity of the decrease in PAF in human plasma. Results: Good linear relation over the range of 1-50 mug/mL of PAF was obtained with regression equation y=0. 284 c+0. 914. r=0.999 1(n=6). At low,middle and high concentrations of quality control sample (3, 20, 40 mug/mL),the intra- and inter-batch RSD were 2.08%-4.75%(n=6) and 5.47%-5.86%(n=18), respectively. Accuracy was 93.50%-97.66% and recovery of PAF and febuxostat (internal standard) was 97.36%-100.8%(n=6). Sample was stable for 12 halter preparation and for 3 freeze-thaw cycles with accuracy ranging from 99.96% to 107.1%(n=6). Results of PAF determination by the developed method showed that PAF concentration of CAD group was significantly higher than that of healthy controls [(22.77 1. 26) mg/mL vs (19.62 3.94) mg/mL, P〈0.05], which indicated a higher activity of LP-PLA_2 in CAD patients than in healthy conlrols. Conclusion: The developed ducible, reliable and has the advantage of high throughput detection, used as a diagnostic marker for CAD and ischemic apoplexy. LC-MS/MS method, which is specific, accurate, repros suitable for determining LP-PLA_2 activity which can be used as a diagnostic marker for CAD and ischemic apoplexy.
