Spirometer was used to determine airway function parameters, enzyme-linked immunosorbent assay kits were used to determine serum cytokine contents, and flow cytometry was used to determine peripheral blood lymphocyte subset contents.Results: FEV1/FVC, FEF25, FEF50 and FEF75 levels, serum IL-2, IFN-γ and TGF-β1 contents as well as peripheral blood Th1 and Treg cell contents of asthma groups were significantly lower than those of control group while serum IL-4, IL-5 and IL-17 contents as well as peripheral blood Th2 and Th17 cell contents were significantly higher than those of control group;FEV1/FVC, FEF25, FEF50 and FEF75 levels, serum IL-2, IFN-γ and TGF-β1 contents as well as peripheral blood Th1 and Treg cell contents of asthma-RSV group and asthma-IFV group were significantly lower than those of pure asthma group while serum IL-4, IL-5 and IL-17 contents as well as peripheral blood Th2 and Th17 cell contents were significantly higher than those of pure asthma group;these indexes of asthma-AV group and asthma-PIV group were not significantly different from those of pure asthma group.Conclusion: RSV and IFV infection can affect the airway function and the balance of CD4+T cell subsets to promote the development of asthma.展开更多

The results indicate that uremia is a kind of selfimmunity disease with abnormal immunoregulation. Therefore, detecting B and T lymphocytes inuremia will be helpful in understanding the pathological mechanism of uremia and evaluation ofprognosis.展开更多
