In order to observe the levels of immune‐associated indicators in patients with sepsis‐induced ALI, we tested the levels of immunoglobulins (IgA, IgM, and IgG) and T lymphocyte subsets (CD3+, CD4+, and CD8+) The results in Table 3 demonstrated that the levels of immunoglobulins and T lymphocyte subsets in sepsis‐induced ALI were lower than those without ALI (all p < 0.05). This evidence concerns the gene CD4 and acute respiratory distress syndrome.
