复发性阿弗它溃疡(RAU)损害先有单核细胞浸润,然后有多形核白细胞进入病灶,伴有免疫复合物介导的脉管炎病变。部份RAU患者外周血也检出免疫复合物(ICs)。有鉴于此,作者根据Lehner提出的轻型复发性阿弗它溃疡(MiRAU)诊断标准选择了21例患者作实验组,31例健康人作正常对照组,另36例已确认患免疫复合物介导疾病的患者(其中7例Sjgren综合征仅累及腺组织,11例Sjgren综合征合并有腺外或结缔组织疾病和18例类风湿关节炎)作疾病对照组。用纯化类
Recurrent aphthous ulcer (RAU) premature mononuclear cell damage infiltration, and then enter the lesion with polymorphonuclear leukocytes, accompanied by immune complex-mediated vasculitis lesions. Some patients with RAU peripheral blood also detected immune complexes (ICs). In view of this, the authors selected 21 patients as the experimental group and 31 healthy individuals as the normal control group according to Lehner's diagnostic criteria for the light recurrence of Afraid ulcer (MiRAU). The other 36 patients were confirmed to have immune complex-mediated (7 cases of Sjgren's syndrome involving only glandular tissue, 11 cases of Sjgren's syndrome with extra-glandular or connective tissue disease and 18 cases of rheumatoid arthritis) as disease control group.
