Abstract:
Objective To investigate the effect of thymosin ?1 (T?1) on cellular immune function in gastric cancer patients through observing its treatment on the differentiation of T-lymphocyte subsets from screened peripheral blood mononuclear cells (PBMCs). Methods PBMCs were obtained by centrifugation of blood samples from 18 healthy subjects and 32 patients with gastric cancer,and then cultured in the presence of culture medium with addition of T?1 at 50,10 and 1 ?g/ml for 2 d. T lymphocyte subsets (such as CD4+,CD8+ and CD4+ CD25+ Foxp3+ T cells) and Th1/Th2 multiplex cytokines were detected by flow cytometry (FCM). Results After PBMCs isolated from healthy people and patients were incubated with or without T?1,there was no significant change in percentage of CD4+,CD8+ peripheral lymphocyte subsets and ratio of CD4+/CD8+. There was no obvious change in the percentage of CD4+ CD25+ Foxp3+ T lymphocyte subsets in the normal control,but a significant increase was observed in the cells from patients with gastric cancer after treatment (P
