摘　　要：目的探索初治慢性乙型肝炎(CHB)患者血清中细胞因子表达水平及其与病毒载量和肝脏炎症程度的关系,以期为临床动态评估CHB的病情和预后提供新思路。方法选择2018年10月至2019年11月就诊于海军军医大学(第二军医大学)第一附属医院感染科的初治慢性乙型肝炎病毒(HBV)感染者68例,健康对照者12名,通过ELISA检测血清中细胞因子IL-17A、IL-2、IL-21和IL-4表达水平,化学发光法检测HBV血清学标志物,qPCR法检测血清HBV DNA定量,全自动生化分析仪检测肝功能指标。采用Spearman相关分析评估血清细胞因子与病毒载量及肝脏炎症程度的相关性,绘制ROC曲线评价血清细胞因子水平对肝脏炎症程度的判断效能。结果相较于健康对照者,初治CHB患者血清IL-17A[17.50(11.99,25.36)pg/mL vs 13.74(9.07,16.94)pg/mL,Z=-2.001,P=0.045]、IL-21[37.12(23.85,77.66)pg/mL vs 20.30(17.90,24.19)pg/mL,Z=-3.485,P<0.01]水平升高,IL-2[57.19(31.10,79.92)pg/mL vs 73.06(62.41,105.84)pg/mL,Z=-2.509,P=0.012]水平降低,IL-4[11.40(5.79,18.62)pg/mL vs 10.84(8.05,25.20)pg/mL,Z=-0.681,P=0.496]水平差异无统计学意义。不同病程CHB患者的IL-17A表达水平差异有统计意义(H=8.870,P=0.031)。与非活动状态患者相比,炎症活动状态CHB患者血清中IL-17A[17.71(12.25,27.92)pg/mL vs 16.51(6.29,20.22)pg/mL]和IL-21[39.29(24.71,83.19)pg/mL vs 25.06(19.37,49.43)pg/mL]水平升高、IL-2[57.19(31.10,77.68)pg/mL vs 71.24(48.07,117.39)pg/mL]水平下降(均P<0.05),IL-4[11.40(5.94,18.12)pg/mL vs 14.57(3.12,24.49)pg/mL]水平差异无统计学意义(P>0.05)。HBeAg阳性CHB患者、HBeAg阴性CHB患者血清IL-17A[15.34(10.65,25.04)、19.98(15.55,34.14)pg/mL vs 13.74(9.07,16.94)pg/mL,H=10.061,P=0.007]和IL-21[37.74(25.06,82.87)、51.74(23.32,83.82)pg/mL vs 20.30(17.90,24.19)pg/mL,H=12.444,P=0.002]水平高于健康对照者,IL-2[57.19(37.45,79.92)、37.45(18.32,73.06)pg/mL vs 73.06(62.41,105.84)pg/mL,H=6.576,P=0.037]水平低于健康对照者。初治CHB患者血�Objective To explore the expression levels of cytokines in serum of treatment-naive chronic hepatitis B(CHB)patients and its relationships with viral load and liver inflammation,so as to provide new ideas for dynamic assessment of disease and prognosis of CHB.Methods A total of 68 treatment-naive patients with chronic hepatitis B virus(HBV)infection,who were admitted to Department of Infectious Diseases of The First Hospital Affiliated to Naval Medical University(Second Military Medical University)from Oct.2018 to Nov.2019,and 12 healthy controls were enrolled.The expression levels of cytokines interleukin(IL)-17A,IL-2,IL-21,and IL-4 in serum were tested by enzyme-linked immunosorbent assay(ELISA).Chemiluminescence method was used to detect HBV serological markers,quantitative polymerase chain reaction(qPCR)was used to detect serum HBV DNA quantification,and automatic biochemical analyzer was used to detect liver function indexes.Spearman correlation analysis was used to evaluate the correlations of serum cytokines with viral load and degree of liver inflammation.Receiver operating characteristic(ROC)curves were drawn to evaluate the efficacy of serum cytokines in judging liver inflammation.Results Compared with the healthy controls,the serum IL-17A and IL-21 levels in the treatment-naive CHB patients were significantly higher(17.50[11.99,25.36]pg/mL vs 13.74[9.07,16.94]pg/mL,Z=-2.001,P=0.045;37.12(23.85,77.66)pg/mL vs 20.30[17.9,24.19]pg/mL,Z=-3.485,P<0.01),the IL-2 level was significantly lower(57.19[31.10,79.92]pg/mL vs 73.06[62.41,105.84]pg/mL,Z=-2.509,P=0.012),and there was no significant difference in IL-4 level(11.40[5.79,18.62]pg/mL vs 10.84[8.05,25.20]pg/mL;Z=-0.681,P=0.496).The expression levels of IL-17A in CHB patients with different disease courses were significantly different(H=8.870,P=0.031).Compared to the patients with inflammatory inactive CHB,the serum IL-17A and IL-21 levels were significantly higher(17.71[12.25,27.92]pg/mL vs 16.51[6.29,20.22]pg/mL and 39.29[24.71,83.19]pg/mL vs 25.06[19.37,4
