Changes in CD4+, CD8+, Th17 and IgG, IgM, and IgA levels. <strong>Methods:</strong> A total of 118 NSCLC patients who attended the Oncology Department of the Affiliated Hospital of Chengde Medical College from September 2018 to September 2021 were selected as the research objects, and the patients were analyzed at different time points (before chemotherapy, after the first chemotherapy, and after the second chemotherapy). The effects of NKG2D, IL-12, IL-15, IL-18, DC cells, TNF-A, IFN-r, CD4+, CD8+ Th17, IgG, IgM and IgA levels in peripheral blood at different time points (before chemotherapy, after the first chemotherapy and after the second chemotherapy) were analyzed. The changes of NKG2D, IL-12, IL-15, IL-18, DC cells, TNF-A, IFN-r and the levels of CD4+, CD8+ Th17, IgG, IgM and IgA in peripheral blood were compared at each time point. <strong>Results:</strong> NKG2D, IL-12, IL-15, IL-18, TNF-a, IFN-r gradually decreased before chemotherapy, one week after chemotherapy, and two weeks after chemotherapy, the difference was statistically significant, but DC cells were not significant Variety. CD4+ and CD8+ both increased significantly, and the levels of Th17, IgG, IgM, and IgA gradually decreased. <strong>Conclusion:</strong> In the course of chemotherapy, all immune factors except DC cells were significantly decreased compared with those before chemotherapy, and the decrease of immune factors except DC cells was positively correlated with the length of chemotherapy cycle. If additional immunotherapy is needed, it should be carried out in the early stage of chemotherapy.展开更多

The difference between each factor of each point was statistically significant (all P < 0.05). Pearson correlation analysis showed that there was no correlation between peripheral blood DC cells of patients at different time points and other factors. <strong>Conclusion:</strong> The decrease of other immune cytokines except DC cells in peripheral blood of patients with NSCLC after chemotherapy may be one of the mechanisms by which the patient’s immune function is suppressed. There is no correlation between DC cells and other factors.展开更多
