反复呼吸道感染(RRI)是儿科常见病、多发病,严重影响儿童健康.我们从1991年9月至1993年8月用红细胞C_3b受体花环试验、红细胞免疫复合物花环试验对56例RRI患儿(其中住院患儿37例,门诊患儿23例)的红细胞免疫功能及其中26例RRI患儿的红细胞免疫调节因子进行了测定,以探讨RRI患儿的红细胞免疫功能状态及其发生改变之原因,现将测定结果报告如下:1.对象和方法1.1 病例选择根据1987年成都全国呼吸道会议制定的诊断标准选择RRI患儿共56例.年龄1～8岁:其中男30例、女26例;就诊时诊断为支气管肺炎者25例,其中合并心衰者7例;支气管炎18例;上呼吸道感染10例;哮喘5例.56例中合并营养性贫血39例(其中轻度贫血24例,中度贫血13例).并与40名健康同龄儿对照。1.2 材料及检测方法红细胞C_3b受体花环试验和红细胞免疫复合物花环试验均由陕西省人民医院免疫研究室提供红细胞免疫功能检测试剂盒测定.方法按刘景田微量常规法进行。循环免疫复合物采
Repeated respiratory infections (RRI) is a common pediatric disease, frequently-occurring disease, seriously affecting children’s health.We have from September 1991 to August 1993 erythrocyte C_3b receptor rosette test, erythrocyte immune complex rosette on 56 cases of RRI children (Including 37 hospitalized children and 23 outpatients), and erythrocyte immunoregulatory factors in 26 children with RRI were measured in order to investigate the status of erythrocyte immune function and its causes in children with RRI , The measurement results are reported as follows: 1. Subjects and methods 1.1 Case Selection According to the diagnostic criteria developed in Chengdu National Respiratory Conference in 1987, a total of 56 cases of RRI children aged 1 to 8 years: 30 males and 26 females; Diagnosis of bronchial pneumonia at diagnosis 25 cases, including 7 cases of heart failure, bronchitis in 18 cases, upper respiratory tract infection in 10 cases, asthma in 5. 56 cases of nutritional anemia in 39 cases (including mild anemia in 24 cases, Moderate anemia in 13 cases), and 40 healthy children of the same age control. 1.2 Materials and testing methods RBC erythrocyte receptor rosette test and erythrocyte immune complex rosette test were provided by the Shaanxi Provincial People’s Hospital Immunology Laboratory erythrocyte immune function test kit determination by Liu Jingtian trace conventional method. Cyclic immune complexes taken
