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

Methods: A total of 48 patients with NSCLC who visited the Oncology Department of the Affiliated Hospital of Chengde Medical College from September 2018 to September 2019 were selected as the study subjects. Changes in the expression levels of NKG2D, IL-12, IL-15 and IL-18 in peripheral blood of patients at different time points (before chemotherapy, after the first chemotherapy and after the second chemotherapy) were analyzed to investigate the correlation between NKG2D and IL-12, IL-15 and IL-18 in peripheral blood at each time point. Results: The expression levels of NKG2D, IL-15, and IL-18 in the peripheral blood of the patient before chemotherapy, after the first chemotherapy, and after the second chemotherapy gradually decreased. After the first chemotherapy and the second chemotherapy, the peripheral blood IL-12 was significantly lower than before chemotherapy, and IL-12 in peripheral blood after the second chemotherapy was slightly increased compared with that after the first chemotherapy. The comparison of each factor at different time points was statistically significant (all P<span style="font-family: ">0.05). Pearson correlation analysis showed that after the first chemotherapy, NKG2D in peripheral blood was positively correlated with IL-18 (r = 0.342, P = 0.031);after the second chemotherapy, NKG2D in peripheral blood was positively correlated with IL-18 (r = 0.411, P = 0.023), negatively correlated with IL-15 (r = -0.451, P = 0.001). Conclusion: There was no significant change in the number of NK cells in the peripheral blood of NSCLC patients after chemotherapy, while NKG2D and related immune cytokines decreased, which may be one of the mechanisms for the suppression of immune function in patients, and this provides a potential target for immunotherapy in patients.展开更多
