    Abstract:
    Objective: To explore the correlation between Semaphorin 4D (Sema4D) and rheumatoid arthritis (RA) clinical manifestations, laboratory indexes, bone destruction and rheumatoid arthritis related interstitial lung disease(RA-ILD), and to analyze its significance in evaluating the severity of patients with rheumatoid arthritis. Methods: A total of 108 RA patients and 50 healthy controls from September 2018 to October 2019 were collected from the Department of Rheumatology and Immunology, Peking University People's Hospital and Beijing Haidian Hospital. According to the DAS 28 score, RA patients were divided into active disease group (DAS28>2.6) and stable disease group (DAS28 ≤ 2.6). Fifty healthy controls. The levels of Sema4D in serum were detected by enzyme-linked immunoassay method (ELISA), and their correlation with clinical manifestations of RA, laboratory indicators, degree of bone damage and RA-ILD were analyzed. Results: The level of serum Sema4D in RA active group was significantly higher than that in stable group and healthy control group (P<0.05). The concentration serum Sema4D was positively correlated with C-reactive protein(CRP) (r=0.28, P<0.05), rheumatoid factor(RF) (r=0.25, P<0.05) and the 28-joint disease activity score (DAS28) (r=0.45, P<0.01). The concentration serum Sema4D was positively correlated with β-Crosslaps(r=0.20, P<0.05) and Sharp-van der Heijde score (SHS)(r=0.13, P<0.05). The concentration serum Sema4D was positively correlated with Vascular endothelial growth factor (VEGF)(r=0.25, P<0.05) and Warrick score of chest CT in RA patients(r=0.27, P<0.05). The anti-cyclic citrullinated peptid(CCP) antibody, DAS28, VEGF and the incidence of RA-ILD were significantly higher than that in Sema4D negative group (P<0.05). Conclusions: Serum Sema4D level in RA patients is closely related to the disease activity, bone destruction and RA-ILD. Serum Sema4D can be used as an indicator of disease monitoring and prognosis evaluation in RA patients. 目的： 检测Semaphorin 4D（Sema4D）在类风湿关节炎（RA）患者血清中的表达水平，探讨Sema4D与RA临床表现、实验室指标、骨破坏及继发肺间质病变（ILD）的相关性，分析其对RA患者病情评价的意义。 方法： 收集2018年9月至2019年10月北京大学人民医院及北京市海淀医院风湿免疫科RA患者共108例，并根据疾病活动指数（DAS）28评分，将RA患者分为病情活动组（DAS28>2.6）与病情稳定组（DAS28≤2.6）。另纳入健康对照者50名。采用酶联免疫吸附试验（ELISA）检测血清中Sema4D的水平，分析其与RA临床表现、实验室指标、骨破坏程度及RA-ILD的相关性。 结果： 血清Sema4D水平：RA病情活动组显著高于病情稳定组和健康对照组（P<0.05）。RA患者血清Sema4D水平与C-反应蛋白（CRP）（r=0.28，P<0.05）、类风湿因子（RF）（r=0.25，P<0.05）、DAS28（r=0.45，P<0.01）呈正相关。RA患者血清Sema4D水平与β-胶原特殊序列（β-Crosslaps）（r=0.20，P<0.05）及双手X线片Sharp-van der Heijde评分（SHS）（r=0.13，P<0.05）呈正相关。RA患者血清Sema4D水平与血管内皮生长因子（VEGF）（r=0.25，P<0.05）及胸部CT的Warrick评分（r=0.27，P<0.05）呈正相关。RA患者Sema4D阳性组的抗CCP抗体、DAS28、VEGF及RA-ILD发生率显著高于Sema4D阴性组（P<0.05）。 结论： RA患者血清Sema4D水平与病情活动、骨破坏及RA-ILD均具有相关性，血清Sema4D可作为RA患者病情监测及预后评估的指标。.
