目的 :探索防治小儿反复呼吸道感染 (RRI)的方法。方法 :将 15 0例患儿随机分成A组 (口服锌硒宝组 ) 80例 ,B组 (肌注人血丙种球蛋白组 ) 70例 ,治疗前后分别检测细胞免疫及体液免疫功能。结果 :A组的总有效率明显高于B组 (P <0 .0 1) ,治疗前后A组的细胞免疫及体液免疫功能发生了显著变化 (P <0 .0 5 ) ,而B组治疗前后细胞免疫功能变化无显著性 (P >0 .0 5 )。结论 :口服锌硒宝能明显提高患儿的免疫力 ,用锌硒宝防治小儿RRI具有较好的远期效果
Objective: To explore the prevention and treatment of recurrent respiratory tract infections (RRI) in children. Methods: A total of 150 children were randomly divided into group A (oral zinc and selenium group) 80 cases, group B (intramuscular injection of blood gamma globulin group) 70 cases before and after treatment were detected cellular immunity and humoral immune function. Results: The total effective rate in group A was significantly higher than that in group B (P <0.01). The cellular immunity and humoral immune function of group A changed significantly before and after treatment (P <0.05), while group B There was no significant difference in cellular immune function before and after treatment (P> 0.05). Conclusion: Oral zinc selenium can significantly improve children’s immunity, with zinc selenium prevention and treatment of pediatric RRI has a good long-term effect
