重症肺炎患儿免疫球蛋白、T淋巴细胞亚群及细胞因子的变化
[Abstract]:Objective: to observe the changes of Ig mg G and CD3~, CD4~, CD8~, Th1,Th2,Th17,IFN- 纬, IL-4,IL-17 in 60 children with severe pneumonia, analyze their immune function and explore their clinical significance, so as to provide basis for immunological treatment of severe pneumonia in children. Methods: 60 children with severe pneumonia admitted in Changchun Children's Hospital from January to December 2016 were selected as observation group and 60 children with mild pneumonia as control group. The changes of Ig mg G and CD3~, CD4~, CD8~, Th1,Th2,Th17,IFN- 纬, IL-4,IL-17 in peripheral blood of 60 children with severe pneumonia and control group were observed by immunoturbidimetry, flow cytometry and ELISA assay. Results: in the observation group, the contents of Ig, CD4~ and CD8~ decreased, the ratio of CD4~ / CD8~ decreased, the Th1,Th17 level was higher than that of the control group, the Th1/Th2 ratio was higher than that of the control group, and the IL-17 content of the observation group was significantly higher than that of the control group. Conclusion: the content of Ig Ag G M in children with severe pneumonia is lower than that in children with severe pneumonia, the level of T lymphocyte subsets in children with severe pneumonia is lower, and the Th1/Th2 imbalance in children with severe pneumonia is lower than that in children with severe pneumonia. There are more severe immune disorders; Th17 cells are involved in the progression of severe pneumonia in children.
