目的 探讨脓毒症患者血中降钙素原（PCT）和C-反应蛋白（CRP）与急性生理学与慢性健康状况评分系统Ⅱ（APACHEⅡ）评分及序贯器官衰竭评分（SOFA）的相关性，以及PCT和CRP对脓毒症预后的评估价值。方法 回顾性分析2011年1月至2014年6月入住第二军医大学附属长征医院重症监护病房（ICU）患者的临床资料，纳入人院24h内行PCT、CRP检测以及APACHEⅡ、SOFA评分的脓毒症患者201例。分析死亡（65例）和存活（136例）患者的PCT、CRP、APACHEⅡ、SOFA评分差异以及不同APACHEⅡ、SOFA评分分层组间PCT和CRP的差异；PCT、CRP与APACHEⅡ、SOFA评分的相关性用Spearman相关分析；绘制受试者工作特征曲线（ROC），评价PCT、CRP对脓毒症患者预后的判断价值。结果与存活组比较，死亡组PCT（μg/L：11．03（19．17）比1．39（2．61），Z=-4．572，P〈0．001]、APACHEⅡ评分（分：19．16±5．32比10．01±3．88，t=-13．807，P〈0．001）、SOFA评分（分：9．66±4．28比4．27±3．19，t=-9．993，P〈0．001）均明显升高，而CRP升高差异无统计学意义[mg/L：75．22（110．94）比56．93（100．75），Z=-0．731，P=O．665]。PCT与APACHEⅡ、SOFA评分均呈显著正相关（rl=0．373，r2=0．392，均P〈0．001），而CRP与APACHEⅡ、SOFA评分均无相关性（r1=-0．073、P1=0．411，r2=-0．106、P2=0．282）。随APACHEⅡ、SOFA评分升高，PCT水平逐渐升高，而CRP水平无明显变化；APACHEⅡ分值0～10分、11～20分、〉20分3组的PCT分别为1．45（2．62）、1．96（9．04）、7．41（28．9）μL，CRP分别为57．50（83．40）、59．00（119．70）、77．60（120．00）mg/L；SOFA分值0～5分、6-10分、〉10分3组的PCT分别为1．43（3．09）、3．41（9．75）、5．43（29．60）肌，ClIP分别为49．30（86．20）、76．00（108．70）、75．60（118．10）mg/L；PCT在APACHEⅡ和SOFA评分各分层组间两两比较差异均有统

ObjectiveTo investigate the correlation between procalcitonin (PCT), C-reactive protein (CRP) and acute physiology and chronic health evaluationⅡ (APACHEⅡ) score and sequential organ failure assessment (SOFA) score, and to investigate the value in assessment of PCT and CRP in prognosis in patients with sepsis.Methods Clinical data of patients admitted to intensive care unit (ICU) of Changzheng Hospital Affiliated to the Second Military Medical University from January 2011 to June 2014 were retrospectively analyzed. 201 sepsis patients who received PCT and CRP tests, and evaluation of APACHEⅡ score and SOFA score were enrolled. The values of PCT, CRP, APACHEⅡ score and SOFA score between survivals (n = 136) and non-survivals (n = 65) were compared. The values of PCT and CRP among groups with different APACHEⅡ scores and SOFA scores were compared. The relationships between PCT, CRP and APACHEⅡ score and SOFA score were analyzed by Spearman correlation analysis. Receiver operating characteristic (ROC) curve was plotted to assess the prognostic value of PCT and CRP for prognosis of patients with sepsis.Results Compared with survival group, the values of PCT [μg/L: 11.03 (19.17) vs. 1.39 (2.61), Z= -4.572,P< 0.001], APACHEⅡ score (19.16±5.32 vs. 10.01±3.88,t = -13.807,P< 0.001) and SOFA score (9.66±4.28 vs. 4.27±3.19,t = -9.993,P< 0.001) in non-survival group were significantly increased, but the value of CRP was not significantly different between non-survival group and survival group [mg/L: 75.22 (110.94) vs. 56.93 (100.75),Z = -0.731,P = 0.665]. The values of PCT were significantly correlated with APACHEⅡ score and SOFA score (r1 = 0.373,r2 = 0.392, bothP< 0.001), but the values of CRP were not significantly correlated with APACHEⅡscore and SOFA score (r1 = -0.073,P1 = 0.411;r2 = -0.106,P2 = 0.282). The values of PCT rose significantly as the APACHEⅡ score and SOFA score became higher, but the value of CRP was not significantly increased. When APACHEⅡ score was 0-10, 11-20, and> 20,
