目的：研究血清降钙素原（PCT ）在重症急性胰腺炎（SAP）患者中表达水平的改变，探讨其在预测SAP患者预后的临床价值。方法对2012年4月至2014年4月48例被确诊的S A P患者进行回顾性分析，分析测定S A P患者住院不同时间段的存活组和死亡组的PCT水平，并同时对存活组和死亡组的急性生理和慢性健康状况（APACHE Ⅱ）评分进行比较。结果存活组和死亡组的临床特征比较，性别、体温、白细胞（WBC ）之间差异无统计学意义，而PC T 水平差异有统计学意义；刚刚入院的PCT 水平和APACHE Ⅱ评分之间差异无统计学意义，在后面的整个治疗过程中，存活组的 PCT 水平、APACHE Ⅱ评分都进行性下降，而死亡组的PCT 水平、APACHE Ⅱ评分则进行性升高。结论 PCT对SAP的预后具有重要的临床价值。%Objective To study the change of serum procalcitonin(PCT) expression level and to investigate its clinical value for predicting the prognosis in the patients with severe acute pancreatitis (SAP) .Methods Totallay 48 inpatients with SAP in our hos‐pital from April 2012 to April 2014 were retrospectively analyzed .The PCT levels during different hospitalization period in the sur‐vial group and the death group were detected and analyzed .The scores of acute physiological and chronic health evaluation Ⅱ (A‐PACHE Ⅱ) were compared between these two groups .Results (1)The clinical characreristics of gender ,body temperature and WBC had no statistically significant differences beween the survival group and the death group (P>0 .05) ,but the PCT level had statistical differencet (P<0 .05) .(2)There was no statistically significant difference in the PCT level and APACHE Ⅱ score at ad‐mission between the two groups .In the later treatment process ,the PCT level and APACHE Ⅱ score in the survival group were progressively decreased ,while which in the death group were progressively inecreased (P<0 .05) .WT5"HZ〗Conclusion PCT has an important clinical value in forcasting the prognosis of SAP .
