摘　　要：目的探讨自身免疫性肝炎(AIH)、原发性胆汁性胆管炎(PBC)及其重叠综合征患者经规范化治疗前后外周血中OX40/OX40L(CD134/CD134L)在CD4+T淋巴细胞、CD8+T淋巴细胞、单核细胞、B淋巴细胞的表达情况及其临床意义。方法选取2015年8月-2019年8月在江苏省苏北人民医院就诊的74例确诊AIH、PBC及其重叠综合征患者,按照相关诊断标准分为AIH组(29例)、PBC组(26例)、重叠综合征组(19例)(即A、P、C组),同时设置健康对照30例。在规范化治疗前后抽取患者外周血标本,采用免疫荧光标记流式细胞术检测OX40/OX40L在外周血细胞表面的表达情况,比较OX40/OX40L在治疗前后、健康对照组的表达差异。多组间比较采用单因素方差分析,进一步两两比较采用LSD-t检验,配对样本两组间比较采用配对t检验。结果3组在性别年龄构成上差异均无统计学意义(P值均>0.05)。治疗前:A、P、C 3组外周血中CD4+T淋巴细胞的OX40阳性率依次升高,且均高于对照组,依次为:(14.80±4.99)%、(17.11±2.71)%、(25.18±5.55)%、(6.67±2.26)%,差异有统计学意义(F=14.823,P<0.001);3组CD8+T淋巴细胞的OX40阳性率均高于对照组,依次为:(4.86±1.54)%、(6.40±1.88)%、(7.33±2.12)%、(4.09±2.69)%,差异有统计学意义(F=5.486,P<0.001);A、P、C 3组及对照组CD14+单核细胞的OX40L阳性率依次为(19.84±6.11)%、(21.17±4.35)%、(29.13±6.32)%、(4.86±2.34)%,差异有统计学意义(F=17.004,P<0.001);但在CD19+B淋巴细胞中,A、P、C 3组的OX40L阳性率却呈现逐渐降低趋势,但仍明显高于对照组,依次为(17.62±3.86)%、(14.75±4.32)%、(10.13±2.56)%、(4.50±1.38)%,差异有统计学意义(F=12.221,P<0.001)。治疗后:CD8+T淋巴细胞的OX40阳性率明显下降,与对照组水平接近,组间差异无统计学意义(F=0.731,P=0.538)。在其余3种细胞中,虽然OX40/OX40L的阳性率与治疗前相比较有不同程度的下降,但仍高于对照组:在CD4+T淋巴细胞中,A、P、C组OX40阳性Objective To investigate the expression and clinical significance of OX40/OX40L(CD134/CD134L)in CD4+T cells,CD8+T cells,monocytes,and B lymphocytes in peripheral blood of patients with autoimmune hepatitis(AIH),primary biliary cholangitis(PBC),and their overlap syndrome before and after standardized treatment.Methods A total of 74 patients with AIH,PBC,and their overlap syndrome who were diagnosed in Subei People’s Hospital of Jiangsu from August 2015 to August 2019 were enrolled,and according to related diagnostic criteria,they were divided into AIH group(group A)with 29 patients,PBC group(group P)with 26 patients,and overlap syndrome group(group C)with 19 patients.A healthy control group with 30 individuals was also established.Peripheral blood samples were collected before and after standardized treatment to measure the expression of OX40/OX40L on the surface of peripheral blood cells by immunofluorescence flow cytometry,and the expression of OX40/OX40L was compared before and after treatment and between the three groups and the healthy control group to investigate its clinical significance.A one-way analysis of variance was used for comparison between multiple groups,and the least significant difference t-test was used for further comparison between two groups;the paired t-test was used for comparison of paired samples between two groups.Results There were no significant differences in sex composition and age composition between the three groups(P>0.05).Before treatment,the positive rate of OX40 in peripheral blood CD4+T cells gradually increased in groups A,P,and C,and groups A,P,and C had a significantly higher positive rate of OX40 than the control group(14.80%±4.99%/17.11%±2.71%/25.18%±5.55%vs 6.67%±2.26%,F=14.823,P<0.001);groups A,P,and C had a significantly higher positive rate of OX40 in CD8+T cells than the control group(4.86%±1.54%/6.40%±1.88%/7.33%±2.12%vs 4.09%±2.69%,F=5.486,P<0.001);the positive rate of OX40L in CD14+monocytes was 19.84%±6.11%in group A,21.17%±4.35%in group P,29.13%±6
