5% versus 5.2%, log-rank test = 60.306; P = 0.000). Conclusion: The GIF scoring system is useful for predicting the AP prognosis. The combination of SOFA and GIF scores has a higher prognostic value than any one of them used alone. Key Word(s): 1. Acute pancreatitis; 2. gut function; 3. organ failure; 4. prognosis; Presenting

Methods: Hct and CRP within 24 h after admission were evaluated, and the differences between severe acute pancreatitis and mild actue pancreatitis were analyzed. The effectiveness in predicting the severity in AP patients was evaluated by ROC curve. Results: The levers of Hct and CRP in

SAP group were significantly higher than those in MAP group (p < 0.05). The sensitivity of CRP and Hct were 66.67% and 50%, the specificity 85.51% and 81.16%, the positive Proteasomal inhibitor predictive value 54.55% and 40.91%, the negative predictive value 90.77% and 86.15%, respectively. The sensitivity of combining CRP and Hct were 66.67%, the specificity 85.51%, the positive predictive value 40.91%, the negative predictive value 90.77%. Conclusion: The earlier period C reactive protein and hematocrit level have prognostic value and combining these two factors are more important in evaluating the severity in patients with acute pancreatitis.

of the 1992 Atlanta criteria for acute pancreatitis (AP) was long awaited. The International Working Group has proposed Clomifene the Revised criteria on the basis of international consensus. This has not been prospectively validated so far. We validate the new definitions of AP in a prospectively followed cohort. Methods: 163 consecutive patients with AP were followed from admission to 6 months after discharge. AP was categorized as mild (MAP) (no local complication[LC] and organ failure[OF]), moderate (MSAP) (transient OF or local/systemic complication but no persistent OF) and severe (SAP) AP (persistent OF), as per the revised definitions. LC included acute peripancreatic fluid collections, pseudocyst, acute necrotic collection and walled off necrosis.
