Objective To retrospectively analyze and compare the curative outcome of hematopoietic stem cell transplantation (HSCT) from HLA identical siblings vs intensive immunosuppression therapy (IST) for severe aplastic anemia (SAA).Methods From January 2008 to December 2010,41 patients with severe aplastic anemia were treated with related HSCT (n =14) or IST (n =27) which combined antithymocyte globulin (ATG) with cyclosporine-A (CsA) therapy.Results All the patients receiving HSCT reached complete response.Among the patients receiving IST,21 patients could be responsive to the therapy,and 2 patients died.There was significant difference in the response rate between HSCT group and IST group (100 % vs 77.8 %,P<0.01 ).Conclusion With the improvement of HSCT technology,the curative outcome of HSCT from HLA identical siblings for SAA is much better than IST.

Objective To analyze the outcome of idarubicin-intensified myeloablastive conditioning regimen in allogeneic peripheral blood stem cell transplantation (allo-PBSCT) in patients with myelodysplastic syndromes (MDS). Methods From August 2004 to July 2009, 12 patients with MDS were treated with alIo-PBSCT following the idarubicin-intensified conditioning regimen. The conditioning regimen was idarubicin (15 mg/m~2), continuous intravenous infusion for 20 h, days-12 to-10; busulfan (0.8 mg/kg), intravenous infusion every 6 h, days-6 to-4; cyclophosphamide (1.8 g/m~2), intravenous infusion every 6 h, days-3 to-2; cyclosporine A combined with short-term methotrexate was used for the prophylaxes of acute graft versus host disease (aGVHD). Results All twelve patients achieved Trilineage engraftment, and were well tolerated to this regimen. Eight patients survived, and the overall survival was 66.7%, disease-free survival (DFS) 58.3%. Two patients relapsed. OS for neither WHO subgroups nor IPSS subgroups had statistically significant difference. Conclusion Allo-PBSCT with idarubicin-inteusified conditioning regimen is an effective treatment with reduction of the relapse rate for MDS patients.

Objective To evaluate the outcome of combination of intensive preconditioning regimen allo-HSCT with imatinib for treatment of Ph chromosome positive acute lymphocyte leukemia (ALL). Methods Between 2009 and 2010, 8 patients diagnosed as Ph+ ALL received allo-HSCT from HLA identical sibling during complete remission. Imatinib was added into the therapies of 5 patients.Seven patients received the intensive preconditioning regimen based on BuCy2, one patient received the regimen of TBI-Cy. A median of 6. 02 × 108/kg mononuclear cells and 3. 14 × 106/kg CD34+ cells were transfused. GVHD prophylaxis included cyclosporine A and methotrexate. Results All patients were well tolerant to the regimen without serious regimen-related toxicity. The median time of ANC≥0. 5 × 109/L was 15. 5 days, and that of PLT≥20 × 109/L was 19 days. Thirty days after allo-HSCT, all patients got donor engraftment successfully. Among 8 cases, 4 cases presented acute GVHD, 2 developed degree Ⅰ , one developed degree Ⅱ , and one developed degree Ⅳ. Seven patients were alive 100 days after allo-HSCT, 3 of whom presented chronic GVHD. At the end of following-up period, 6 patients were alive, among them, 3 patients were alive without relapse; 3 patients relapsed; Two patients died, one from acute GVHD, and one from leukemia relapse. Conclusion Combined intensive preconditioning regimen allo-HSCT with Imatinib was an effective treatment for Ph+ ALL, but the effect of anti-chronic GVHD of imatinib should arouse certain attention.

Objective To investigate the clinical characteristics of acute inhalational metallic nickel poisoning and its treatment effect.Methods Data including epidemiology,clinical features,laboratory tests,imaging examinations,therapy protocol as well as prognosis were collected and analyzed.Results Thoracic CT scan of all patients demonstrated as bilateral diffuse infiltration.Nickel concentration in both blood and urine were high in all patients and the concentration was positively associated with poisoning severity.All 4 patients received glucocorticoid treatment,2 of whom with acute respiratory distress syndrome were admitted to ICU to initiate mechanical ventilation and were given sodium dimercaptopropanesulfonate.All patients survived to hospital discharge.Conclusions Acute inhalational metallic nickel poisoning is uncommon and early symptoms are inconclusive.The blood and urine nickel concentration is helpful to judge the severity of the disease.Pulmonary diffuse infiltration is the main clinical feature.Glucocorticoid,chelation therapy as well as symptomatic treatment are effective therapies to relief disease severity.

The kinetics of nicotine degradation by O.intermedium DN2 and its application in tobacco waste were investigated. The results showed that the optimum temperature of nicotine degradation by O.intermedium was 30 ℃, the pH value was 6.5 and a mount of inoculum was 5 %. Under above conditions, the kinetics of nicotine degradation of initial concentration 500 mg/L was studied. The results indicated that the degradation process of nicotine with no-induced strain DN2 followed inverse S-shaped curve, and degradation process of nicotine with induced cells of DN2 followed Eckenfelder mode. The half life of nicotine degradation was 17.43 h and 4.10 h, respectively. And the results also showed that tolerance of O.intermedium DN2 to nicotine was up to 5000 mg/L when 0.1 % of glucose was added. Nicotine (2 220 mg/L) in extract of tobacco wastes degraded about 95.22 % by strain DN2 in 60 h incubation, indicating that strain DN2 was of application value in treatment nicotine pollution.
