Objective To evaluate the effect of inducing differenation of all trans retinoic acid (ATRA) on immunologic function of patients with gastric cancer. Methods T-lymphocyte subsets(T-Ls) and interleukin-2 receptor(sIL-2R) of 56 patients with gastric cancer after treatment of ATRA were studied. Results In radical gastric cancer resection group, the serum CD3,CD4 and CD4/CD8 rate were higher and sIL-2R were lower than those in the control group, after treatment of ATRA, CD3,CD4 and CD4/CD8 rate and sIL2R were as high as those in the control group. In the non-operative or palliative gastric resection group, CD3,CD4 and CD4/CD8 rates were increased markedly and the serum sIL-2R was decreased significantly than those in the control group. Conclusion ATRA inducing differenation can improve the immunity of the patients with gastric cancer.
To evaluate the effect of intraperitoneal hyperthermo-chemotherapy (IPHC) on immunologic function of patients with gastrointestinal malignant tumor (GMT). The authors determined the serum T-lymphocyte subsets (T-LS) and interleukin-2 receptor (sIL-2R) of 32 patients with GMT after IPHC, and compared the two indexes with 20 healthy control group. Results: Before IPHC the serum CD+3, CD+4, CD+8 and CD+4/CD+8 were higher and sIL-2R were lower than control group, after IPHC, CD+3, CD+4, CD+8 and CD+4/CD+8 increased obviously (P<0.01) and the serum sIL-2R decreased significantly (P<0.01). Conclusion: The IPHC can improve the patients immunologic function.
Objective To study the regulative effect of angelica sinensis on cellular immune function in perioperative patients with obstructive jaundice. Methods Fourteen patients with obstructive jaundice were injected with angelica before and after operation for 14 days. The activity of IL-2 and the expression of IL-2R in lymphocytes in peripheral blood were measured, respectively. Results The activity of IL-2 and the expression of IL-2R decreased significantly in patients with obstructive jaundice (P<0.01). The activity of IL-2 and the expression of IL-2R in peripheral blood lymphocyte increased significantly before and after operations (after treatment using angelica) (P<0.01), though there was a little decrease after operation but they were still higher than that befor using angelica.Conclusion It maybe useful to use angelica to improve the cellular immune function in patients with obstructive jaundice.
