贲门癌患者外周血CD4+CD25hiCD127low调节性T细胞水平及其临床意义

Objective To analyse the dysfunction of immunity and clinical significance in patients with cardiac cancer.Methods The level of CD4+ CD25hi CD127low Treg cells were detected by flow cytometry (FCM),and serum IL-10 and TGF-β1 levels were determined by enzyme linked immunosorbent assay (ELISA) kit in 56 patients with cardiac cancer.15 healthy volunteers were tested as normal controls.The clinical data of each patient were collected and analyzed. Results There was a significantly higher percentage of CD4+ CD25hi CD127low Treg cells in patients with cardiac cancer (5.73±1.56)% than that (4.45±1.06)% of healthy volunteers (P<0.01).The IL-10 and TGF-β1 levels in the serum of patients with cardiac cancer were also significantly higher than that of healthy volunteers (P<0.05).There was a positive correlation between levels of IL-10.TGF-β1 and the levels of CD4+ CD25hi CD127low Treg cells.The number of CD4+ CD25hi CD127low regulatory T cells in the peripheral blood of cardiac cancer patients were significantly correlated with clinical stages and metastasis lymph node.Conclusion The CD4+ CD25hi CD127low Treg cells in the peripheral blood of cardiac cancer patients is significantly increased in comparison with that in healthy volunteers,and was also correlated with different stages.The abnormal levels of CD4+ CD25hi CD127low Treg cells may be related to tumor progression in patients with cardiac cancer.     

肺癌患者外周血CD+4CDHi25CDLo127调节性T细胞检测的临床意义

Objective To evaluate the changes and clinical significance of CD+4CDHi25CDLo127 regulatory T cell(Treg) in peripheral blood of patients with lung cancer. Methods 30 patients with lung cancer and 20 heathy volunteers were included in this study. The proportion of Treg population in CD4+ T cells stained with three colors was analysed by flow cytometry. The serum level of IL-10 and TGF-β were measured by ELISA. Results The proportion of Treg in patients with squamous cell careinoma(n=20), adenocarcinoma (n=10) were all significantly higher than that of healthy controls (P <0.05), but there was not obvious difference between the two groups with different pathological types(P0.05). Increased serum level of IL-10 and TGF-β was also detected in lung cancer patients. Conclusion The proportion of Treg is increased in lung cancer patients, which may result in the inhibition of host anti-cancer immune response by excreting IL-10 and TGF-β.
