目的分析影响脓毒症患者预后的因素并评估其预后诊断价值。方法采用前瞻性、临床病例分析研究，共纳入广州医科大学附属第一医院重症加强治疗病房（ICU）2012年10月17日至2013年8月8日收治的脓毒症患者53例，以同期35例健康体检者为健康对照组。根据脓毒症严重程度将患者分为脓毒症组、严重脓毒症组和脓毒性休克组；根据急性生理学与慢性健康状况评分系统Ⅱ（APACHEⅡ）评分将患者分为低危组（APACHEⅡ评分＜10分），中危组（APACHEⅡ评分10-19分），高危组（APACHEⅡ评分≥20分）。根据患者是否出现过凝血功能障碍及凝血功能障碍至观察终点时是否得到纠正将患者分为无凝血功能障碍组、凝血功能障碍纠正组、凝血功能障碍未纠正组。入组后记录患者的性别、年龄、体温、血压、凝血酶原时间（PT）、凝血酶原活动度（PTA）、活化部分凝血活酶时间（APTT）、国际标准化比值（INR）、D-二聚体、纤维蛋白原（Fib）、血乳酸及血清降钙素原（PCT）等临床资料，并进行APACHEⅡ评分。24 h内采集血液标本，运用Bio-Plex悬液芯片技术检测血浆白细胞介素（IL-6、IL-8）含量。采用二分类多变量logistic回归分析筛选脓毒症相关的预后因素，运用受试者工作特征曲线（ROC曲线）评价血乳酸、PCT、IL-6和IL-8及APACHEⅡ评分对脓毒症患者预后的诊断价值。结果纳入的53例患者中：脓毒症组17例，8例患者出现凝血功能障碍，其中7例得以纠正，死亡5例；严重脓毒症组15例，7例患者出现凝血功能障碍，其中2例得以纠正，死亡7例；脓毒性休克组21例，18例患者出现凝血功能障碍，其中4例得以纠正，死亡18例。脓毒症组IL-6、IL-8水平均明显高于健康对照组（P＜0.01）。单变量logistic回归分析显示，脓毒症分级、APACHEⅡ评分、IL-6、IL-8、血乳酸、PCT及凝血功能障碍与患

Objective To analyze the potential factors affecting the prognosis of patients with sepsis and evaluate their values in predicting the disease outcome. Methods A clinical prospective study was conducted. Fifty-three septic patients admitted to intensive care unit （ICU） of the First Affiliated Hospital of Guangzhou Medical University from October 17th, 2012 to August 8th, 2013 were enrolled, and in the same term 35 volunteers having passedphysical check-up were assigned in the healthy control group. According to the severity of the patients, they were divided into sepsis, severe sepsis and septic shock groups. Furthermore, based on the difference in scores of acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ）, the patients were divided into low-risk （APACHE Ⅱ scores 〈 10）, middle-risk （APACHE Ⅱ scores 10 - 19） and high-risk groups （APACHE Ⅱ scores≥ 20 ）. According to whether the coagulation dysfunction occurred or not and whether the dysfunction was adjusted or not at the end of observation, the septic patients were divided into non-coagulation defect group, and adjusted and non-adjusted coagulation defect groups. After entrance of groups, the clinical data, including gender, age, body temperature, blood pressure, prothrombin time （PT）, prothrombin time activity （PTA）, activated partial thromboplastin time （APTT）, international normalized ratio （INR）, levels of D-dimer, fibrinogen （Fib）, blood lactate, and serum procalcitonin （PCT） were recorded, and APACHEⅡscore was calculated. In 24 hours after admission, blood samples were collected, and the levels of interleukins （IL-6, IL-8） were tested by Bio-Plex 200 System. The prognostic factors related to sepsis were screened by binary multivariate logistic regression analysis. The receiver operating characteristic curve （ROC） were used to evaluate the prognostic values of blood lactate, PCT, IL-6, IL-8 and APACHE Ⅱ scores for patients with sepsis. Results Fifty-three patients were enrolled, i
