摘 要:目的探讨pSS唇腺淋巴细胞免疫表型是否与患者唇腺及外周血临床特征具有一致性。方法收集我院风湿免疫科收治的pSS患者71例,对照组35例来自我院健康体检者及行颌面部手术的外科疾病患者,对唇腺浸润的淋巴细胞进行免疫表型分析,依据免疫组织化学染色所示CD20、CD3表达的不同将患者分为CD20高表达组和CD20低表达组,分析患者与对照组之间及2组患者之间在年龄、病程、ESR、CRP、唇腺及血清免疫球蛋白、补体水平的差异。采用t检验和秩和检验进行统计学分析。结果①pSS血清IgG、IgA、IgM、ESR、CRP水平高于对照组[IgG:(22990±8060)mg/L与(11560±1290)mg/L,t=11.645,P〈0.01;IgA:(3710±1400)mg/L与(2390±800)mg/L,t=6.138,P〈0.01;IgM:(1580±1300)mg/L与(920±390)mg/L,t=3.893,P〈0.01;ESR:(37±14)mm/lh与(14±4)ram/1h,t=12.723,P〈O.01;CRP:(5.9±8.7)mg/L与(2.5±1.2)mg/L,t=3.199,P〈O.01],c4水平低于对照组[(180+60)mgm与(250±40)mg/L,t=-6.850,P〈O.01],c3水平差异无统计学意义[(940±240)mg/L与(1000±120)mg/L,t=1.670,P〉O.05]。②pSS唇腺IgG、IgA、IgM、C3c表达高于对照组(IgG:z=-6.264,P〈O.01;IgA:Z=-1.997,P〈O.05;IgM:在-5.459,P〈O.01;C3e:Z=-8.533,P〈O.01),Clq表达低于对照组(Z=-4.363,P〈O.01)。③DSS患者的唇腺标本均存在CD20表达,其中66例同时存在CD3表达,5例患者CD3表达阴性。④CD20高表达组血清IgG水平高于低表达组[(2497±751)mg/L与(1886±774)mg/L,t=3.176,P〈O.01],CD20高表达组ESR水平高于低表达组[(40±13)mndlh与(32+15)ram/1h,t=2.148,P〈O.05],2组I甜、IgM、C3、C4、CRP比较差异无统计学意义[IgA:(376±134)mg/L与(360±155)mg/L,t=0.458,P〉O.05;IgM:(150±97)mg/L与Objective To investigate the consistency of the lymphocyte immunophenotype between labial gland and peripheral blood of patients with primary Sj6gren's syndrome (pSS). Methods Seveny-one pSS patients (referred as pSS group) from rheumatology department and 35 subjects patients with maxillofacial trauma (referred as control group) from department of head and neck surgery of general hospital at tianjin medical university (Tianjin, China) during August 2013 to April 2016 were included into this study. Based on the ratio of CD20 to CD3 in labial gland from pSS patients, they were divided into CD20 high proportion group and CD20 low proportion group. Lymphocyte immunophenotypes in labial glands, course of disease, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, immuno-globulin (Ig) and complement levels were compared among groups. Results (1) The levels of serum IgG, IgA, IgM and CRP, and ESR were higher, but C4 level was lower in pSS patients than in the control group [IgG: (22 990±8 060) mg/L vs (1 1560±1 290) mg/L, t=11.645,P〈0.01; lgA: (3 710±1 400) mg/L vs (2 390±800) mg/L, t=6.138, P〈0.01; IgM: (1 580±1 300) mg/L vs (920±390) mg/L, t=3.893, P〈0.01; ESR: (37±14) mm/1 h vs (14±4) mm/1 h, t=12.723, P〈0.01; CRP: (5.9±8.7) mg/L vs (2.5±1.2) mg/L, t=3.199, P〈0.01; C4: (180±60) mg/L vs (250±40) mg/L, t=-6.850, P〈0.01]. (2) The levels of IgG, IgA, IgM and C3c in labial gland were higher (IgG: Z=-6.264, P〈0.01; IgA: Z=-1.997, P〈0.05; IgM: Z=-5.459, P〈0.01; C3c: Z=-8.533, P〈0.01), but Clq was lower in pSS group than in control group (Z=-4.363, P〈0.01). (3) CD20 was detected in labial gland samples of all pSS patients, in which CD3 was positive in 66 patients, and negative in 5. (4) Serum IgG level, ESR were higher in CD20 high proportion group than in low proportion group [IgG: (24 970±7 510) mg/L vs (18 860±7 740) mg/L, t=3.176, P〈0
