Objective To evaluate the effect of cytokine-induced killer cells (CIKs) as an adoptive immunotherapy option for treatment of leukemia relapse after allo-hematopoietic stem cell transplantation (allo-HSCT).Methods Two cases of infusion of donor CIKs in patients with leukemia relapse after allo-HSCT were retrospectively analyzed.Patient one relapsed 986 days (+986d) after HLA-matched unrelated donor allo-HSCT.Applications of chemotherapy only resulted in short term remission,but allo-CIKs were successfully expanded from the patient's peripheral blood mononuclear cells of donor origin.Totally five cycles of CIKs infusion were infused as an alternative of adoptive immunotherapy.Patient two had recurrent in the + 158d after HLA-matched sibling alloHSCT.At + 204d and + 294d,two cycles of CIKs which were expanded from donor peripheral blood mononuclear cells were infused.Results One cycle of CIKs was given to patient one after the application of chemotherapy to reduce the tumor burden,and the patient successively achieved complete remission.Again after additional four cycles of CIKs infusion,consistent remission was maintained during the following seven months.Patient two who had relapsed disease posttransplantation,achieved cytological complete remission after withdrawal of immunosuppressants and undergoing chemotherapy combined with G-CSF mobilized stem cell infusion.However,at + 187d,the patient suffered from side-effect of acute graft versus host disease and extramedullary infiltration.The symptoms were alleviated markedly after one cycle of CIKs infusion at + 204d.Moreover,the pain disappeared after an additional infusion at + 294d.And up to the present,the bone marrow aspiration showed complete remission while the extramedullary disease vanished.Conclusion The use of CIKs in the treatment of leukemia relapse after allogeneic bone marrow transplantation can be feasible and well tolerated.

PURPOSE: To know whether the cardiac function of the patients with heart disease is impaired or improved after long-term taking ?-AR antagonists. METHODS: After giving the rats ?-AR selective antagonist, atenolol, for 12wk, the method of radioligand binding assay and the experiment of isolated left-atrium contractive function were carried out to observe the quantity and distribution of ?-AR, its subtypes, ?-AR, and the change of left - atrium contractive function. RESULTS: After long-term administration of atenolol, there were no any obvious changes in ?-AR, the density of the total ?-AR, ?1-AR, and the proportion of ?2-AR in tota1 amount of ?-AR, but the con centrat ion - response cu rves shi fted l e ftwa rd s si gn ifi cant ly as compared with control group- The PA2 value of isoprotenol(ISO) - induced positive inotropic effect after antagonized by ?1-AR selective antagonist CGP20712A in atenolol group was increased significantly as compared with control group. But the PKB value after antagonized by ICI 118511 showed no obvious difference between two groups. HPLC detection showed that the level of plasma atenolol was 3. 5pmol/L in atenolol group and the leveIs of plasma norepinephrine had no significant difference between two groups. But the level of plasma adrenaline in atenolol group was obviously lower than that in control group. CONCLUSIO- N: The long-term administration of ?l-AR antagonist will cause significant increase of the sensitivity of heart ?-AR, especially ?1-AR to excitant ISO. But the number of ?-AR and its subtypes did not change significantly. Besides, after the long-term administration of ?1-AR antagonist atenolol, the level of plasma adrenaline in rats was much lower than that in control group.
