摘　　要：目的探讨细胞因子、降钙素原(procalcitonin,PCT)及中性粒细胞-淋巴细胞比值(neutrophil-lymphocyte ratio,NLR)在脓毒症患者早期诊断及预后评价中的价值。方法选取空军军医大学第一附属医院2020年1月~2023年1月收治的98例脓毒症患者作为研究对象,其中脓毒症休克组16例和非休克组82例;另根据患者28天的生存情况,将其分为生存组(n=82)和死亡组(n=16);选取同期95例非脓毒症感染者作为对照组。采集患者入院24h内的外周静脉血,检测白细胞介素(interleukin,IL)-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-17,肿瘤坏死因子(tumor necrosis factor,TNF)-α,干扰素(interferon,IFN)-γ,IFN-α,PCT和NLR的表达水平。应用受试者工作特征(receiver operator characteristic,ROC)曲线分析各炎性指标对脓毒症患者诊断及不良预后的预测价值。结果(1)脓毒症组除IL-1β和IFN-γ外,其余炎性指标均高于非脓毒症感染组,差异具有统计学意义(Z=0.43~30.54,均P<0.05)。其中IL-8,NLR,PCT和IL-17预测脓毒症的能力较强,曲线下面积(area under curve,AUC)分别为0.78(95%CI:0.71~0.84),0.81(95%CI:0.75~0.87),0.83(95%CI:0.78~0.88),0.86(95%CI:0.81~0.92),联合检测四种指标AUC可达到0.90(95%CI:0.85~0.93),能有效提高诊断效能;(2)脓毒症血培养阳性组和阴性组的细胞因子,PCT和NLR表达水平差异均无统计学意义(P>0.05),提示这些炎性指标不受血培养检测结果影响;(3)脓毒症休克组IL-6[122.10(10.77~10000.00)ng/L]表达水平明显高于非休克组[25.56(1.02~9096.74)ng/L],差异具有统计学意义(Z=74.55,P=0.01),AUC为0.73(95%CI 0.59~0.87);死亡组IL-10[10.69(1.12~1338.00)ng/L],IL-2[12.52(0.86~280.42)ng/L]和IL-5[9.55(0.93~259.57)ng/L]的表达水平均高于生存组[2.55(0.34~695.13)ng/L,4.46(0.13~625.43)ng/L,2.75(0.01~117.88)ng/L],差异具有统计学意义(Z=3.64,6.37,4.74,均P<0.05),三者预测脓毒症预后的AUC分别为0.69(95%CI:(0.53~0.85),0.71(95%CI:0.56~0.85),0.72(95%CI:0.58~0.87)。结论IL-8,NObjective To explore the value of cytokines,procalcitonin(PCT)and neutrophil-lymphocyte ratio(NLR)in the early diagnosis and prognosis evaluation in the patients with sepsis.Methods 98 patients with sepsis admitted to the First Affiliated Hospital of Air Force Medical University from January 2020 to January 2023 were selected as research objects,including 82 patients in the sepsis non-shock group and 16 patients in the sepsis shock group.According to the death within 28 days,the patients was divided into survival group(n=82)and death group(n=16).Meantime,95 cases of non-septic infection group were included as control.The expression of interleukin(IL)-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-17,tumor necrosis factor(TNF)-α,interferon(IFN)-γ,IFN-α,PCT,and NLR were detected within 24h after admission,and their relationship with sepsis was analyzed by ROC curve.Results①The IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-17,TNF-α,IFN-α,NLR and PCT in patients with sepsis were significantly higher than those in healthy subjects(Z=0.43~30.54,all P<0.05)except IL-1β,IFN-γ.Further analysis of ROC showed that IL-8,NLR,PCT and IL-17 had strong predictive ability,with area under curve(AUC)of 0.78(95%CI:0.71~0.84),0.81(95%CI:0.75~0.87),0.83(95%CI:0.78~0.88),0.86(95%CI:0.81~0.92),respectively.Combined detection of the four indicators can effectively improve the diagnostic efficiency of sepsis,with the AUC of 0.90(95%CI:0.85~0.93).②There were no significant differences in cytokines,PCT and NLR concentration between positive and negative blood culture groups(P>0.05),suggesting that these indexes were not affected by blood culture detection results.③Among the patients in the shock group,IL-6[122.10(10.77~10000.00)ng/L]was significantly higher than that in non-shock group[25.56(1.02~9096.74)ng/L],the difference was statistically significant(Z=74.55,P=0.01),with the AUC of 0.73(95%CI:0.59~0.87).The levels of IL-10[10.69(1.12~1338.00)ng/L],IL-2[12.52(0.86~280.42)ng/L]and IL-5[9.55(0.93~259.57)ng/L]in sepsis death group
