Abstract：Objective To analyze the serum proteomic pattern in different severe acute pancreatitis complication by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) for evaluating the stage and prognosis of severe acute pancreatitis. Methods Serum samples were collected from 23 severe a-cute pancreatitis. Serum from organ nonfunction, pancreatic abscess, intra-abdominal hypertension and death were profiled using WCX Proteinchip and analyzed by mass spectrometry. Results Protein peak in the spectrum characteristics showed that at 1094u, 2751u, 5904u, the peak value of concurrent pancreas abscess pancreatitis [13.21 ± 3.73, 45.62±10.31, 48.37±9.24] were significantly higher than those in none-pancreas abscess group [4.33 ± 1.79, 8. 87 ±3.21, 4.45 ±1.59] (P<0.05). At 635u, the peak value of concurrent organ failure group(8.56 ± 3.21) was obviously lower than those in none-organ failure group(37.82 ± 12.65). At 4103u and 4187u, the peak value of in complicated organ failure group [21.63 ±8.23, 9.81±2.32] were higher than those in none-organ failure group [3.32±1.29, 1.14 ±0.49], At4173u, the peak value of concurrent increased intraabdominal pressure group(8.94 ±3.58) was significantly higher than that in none-intraabdominal pressure group(1.97 ±0. 73) , while at 5635u the peak value of concurrent increased intraabdominal pressure groups ( 0. 62 ± 0. 23 ) was lower than that without intraabdominal pressure group (15.78 ±6.34). Two cases died. Protein fingerprints showed that overall serum protein composite function dropped and the peak value reduced. Conclusion Proteomic technology can significantly identify novel significant biomarkers in the serum, which provides a new way to diagnose and treat the different complication of severe acute pancreatitis early and has clinical significance in evaluating the prognosis of severe acute pancreatitis.
