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

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

In this article, we studied the effect of Fuzheng Jiedu granule on immunological function and the expression of immune-related cytokines in immune-suppressed mice. 72 mice were randomly divided into six groups, with 12 in each group. The control groups included an untreated group, a negative control group(Cyclophosphamide) and a positive control group(Astragalus polysaccharide). There were three treated groups, which were given different doses of Fuzheng Jiedu granule: a low dose(100 mg kg^(–1)), a medium dose(400 mg kg^(–1)) and a high dose(600 mg kg^(–1)). With the exception of the untreated control animals, each group received an intraperitoneal injection of Cyclophosphamide(100 mg kg^(–1)) for 3 days to establish the immune-suppressed model. Mice were then treated for 19 consecutive days and, 24 h after the last treatment, blood was taken for the eyeballs and serum separation was performed. Analysis was made of the levels of related cytokines(IgA, IgG, IgM, IL-6, IFN-γ, C3, C4 and TNF-α), the transformation of lymphocytes and the immune organ indexes. The results showed that Fuzheng Jiedu granule can improve the levels of cytokines, the rate of proliferation of lymphocytes and the immune organ indexes of immune-suppressed mice.展开更多

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 blood levels of interleukin-12 (IL-12), interleukin-15 (IL-15), interleukin-18 (IL-18), dendritic cells (DC cells), tumor necrosis factor A (TNF-a) and the levels of immune interferon (IFN-r) and NK cell activating receptor (NKG2D) in blood before chemotherapy, after the first chemotherapy and after the second chemotherapy were analyzed. <strong>Results:</strong> Except for the viability of DC cells and DC cells, all other immune factor groups showed statistical differences. <strong>Conclusion: </strong>Chemotherapy will have a negative effect on all immune factors except DC cells. The effect of immune factors will be weakened according to the increase of the chemotherapy cycle. Therefore, immunotherapy for non-small cell lung cancer needs to be carried out before chemotherapy or in the early stage of chemotherapy to achieve better results.展开更多

Investigations of immune system problems in ASD, including aberrations in cytokine pro?les and signaling, have been increasing in recent times and are the subject of ongoing interest. With the aim of establishing whether cytokines have utility as potential biomarkers that may de?ne a subgroup of ASD,or function as an objective measure of response to treatment, this review summarizes the role of the immune system, discusses the relationship between the immune system, the brain, and behavior, and presents previouslyidenti?ed immune system abnormalities in ASD, speci?-cally addressing the role of cytokines in these aberrations.The roles and identi?cation of biomarkers are also addressed, particularly with respect to cytokine pro?les in ASD.展开更多
