Objective To investigate the effect of allgeneic hematopoietic stem cell transplantation (allo-HSCT) for β-thalassemia major. Methods Twenty-four β-thalassemia major patients with median age of 4 years (range: 2～15 years), 18 boys and 6 girls, received allo-HSCT.They were classified into class Ⅱ-Ⅲ according to Pesaro thalassemia classification. Twenty-three transplantations were from sibling donor and 1 was from mother, either HLA-identical (n = 23) or HLA-mismatched (5/6) (n = 1). Fifteen patients received bone marrow transplantation (BMT) plus peripheral blood stem cell transplantation (PBSCT), and 9 were subjected to umbilical cord blood transplantation (UCBT). The conditioning regimen consisted of busalphan, cyclophosphamide,fludarabine, plus hydroxyurea before transplantation. Graft-versus-host disease (GVHD) prophylaxis included CsA, methotrexate, antilymphpcute globulin, and mycophenolate mofetil. The median follow-up period was 13 months (range: 3～69). Results Of 24 patients, there were 21 cases (87. 5 %) of disease-free survival, 1 (4. 2 %) transplantation-related death, and 2 cases (8. 3 %) of rejection. Three-year overall survival and disease-free survival rate was 91.7 % and 87. 5 %respectively. The cumulative incidence of grade Ⅱ -Ⅳ acute GVHD and chronic GVHD was 16. 7 %and 20. 3 %, particularly cumulative extensive chronic GVHD was 5. 0 %. Conclusion The sibling donor BMT plus PBSCT is an effective and safe way to treat β-thalassemia major. Cord blood is an important source of hematopoietic stem cells for HSCT. The protocol GVHD prophylaxis of CsA,MTX, ATG with a low-dose and short course of MMF can effectively reduce the incidence of severe acute GVHD, improve the outcome of thalassemia transplantation.

Objective: To explore the diagnosis, treatment and prognosis of autoimmune hemolytic anemia (AIHA) after allo-HSCT in patients with thalassemia major (TM). Methods: A retrospective analysis of AIHA status after allo-HSCT in 291 TM patients from July 2007 to December 2017 was conducted. Results: Five of the 291 TM patients (1.72%) were diagnosed with post-transplant AIHA. The median time of AIHA was 7 (5-12) months after HSCT. All post-transplant AIHA patients were positive in direct and indirect Coombs test, the main clinical manifestations were dizziness, fatigue, pale complexion, skin and sclera yellow, and soy sauce urine. The incidence of AIHA was higher after unrelated donor transplantation (6.36%, 4/63) compared with that of sibling donor transplantation (0.43%, 1/228). One patient who received only prednison was dead. Four patients who received rituximab combined with prednisolone were alive, Coombs test in two of them were negative. Conclusions AIHA after allo-HSCT developed in 1.72% patients with TM. Monitoring of Coombs test was important for diagnosis of post-transplant AIHA. The incidence of post-transplant AIHA was higher in unrelated donors compared with that of sibling donors transplantation. Treatment of rituximab combined glucocorticoid was effective strategy for post-transplant AIHA.

Objective:To investigate the relationship between the expression of hepatocyte nuclear factor-1 α (HNF-1α) and the occurrence and development of liver inflammation and fibrosis in liver tissues of patients with chronic hepatitis B.Methods:Sixty-four patients with chronic hepatitis B who were diagnosed and treated in our hospital from 2011 to 2018 were selected. All patients underwent ultrasound-guided aspiration liver biopsy. The pathological results of liver biopsy were collected for inflammation grading and fibrosis staging. The liver puncture biopsies was collected by paraffin sectioning. The expression of HNF1α in the liver tissue was detected by immunohistochemical staining. Mantel-Haenszel χ2 test was used for bidirectional ordered grouping data, and Spearman’s rank-correlation test was used for rank correlation analysis. Results:There were varying degrees of inflammatory necrosis and fibrosis in the liver tissues of patients with chronic hepatitis B. There was a linear relationship between the expression of HNF1α and the level of inflammation in liver tissues ( χ2MH = 40.70, P < 0.05). The expression of HNF1α in liver tissues of patients with chronic hepatitis B was decreased with the increase of liver inflammation. The expression intensity of HNF1α was negatively correlated with the inflammation grade ( rs = -0.815, P < 0.05). There was a linear relationship between the expressions of HNF1α and the degree and stage of liver fibrosis ( χ2MH = 31.95, P < 0.05). The expression level of HNF1α in liver tissue was gradually decreased with the aggravation of liver fibrosis. The expression intensity of HNF1α was negatively correlated with fibrosis stage ( rs = -0.713, P < 0.05). Conclusion:HNF1α is closely related to the occurrence and development of liver tissue inflammation and fibrosis, and is expected to be a sensitive indicator for evaluating the level of liver tissue inflammation and fibrosis in patients with chronic hepatitis B. In addition, its down-regulation may be involved in the process of occurrence and development of liver inflammation and liver fibrosis, and may become a new target for the treatment of chronic hepatitis B.

Objective: To further observe the efficacy of combined transplantation of islet and bone marrow mesenchymal stem cells (BMSC) in diabetic rats, PET-CT was used to trace cells in vivo to determine the homing and distribution of cells in vivo. Methods: Streptozotocin (STZ)was used to construct a rat model of diabetes mellitus. BMSC could be isolated and cultured by full adherence method; islets were isolated by collagenase; Islets and BMSC were labeled with 18F-FDG in vitro. Diabetic rats were randomly divided into 4 groups, 15 rats in each group: A, Control group; B, Stem cell transplantation group; C, Islet Transplantation group; D, Combined transplantation group, a total of four groups, all transplanted through portal vein, PET-CT tracing the distribution of cells transplanted into the body.7 days after transplantation, the livers of each group were taken, and the homing and distribution of transplanted cells were detected by immunofluorescent staining.The SUV was calculated by the analysis of variance of random block, and the difference between groups was compared by t-test. Results: PET-CT results showed that BMSC were mainly distributed uniformly in the right liver, and the islets of the pancreas were mainly clustered in terminal branches of hepatic portal vein, and BMSC were around the islets of pancreas, but there was no obvious development in the liver of the control group. Conclusions PET-CT can directly reveal the distribution of islets and BMSC in liver after transplantation through portal vein.

【Objective】 To explore the challenging blood cross-matching and resolution for multiple myeloma (MM) patients in different disease stages. 【Methods】 For a patient who was first diagnosed as MM and scheduled for blood transfusion, his blood was cross matched with donors’ blood by microcolumn gel method and tube test. When the major side of cross-matching was agglutinated, the patient’s plasma was cross matched with donors’ red blood cell (RBC) by polybrene test, then plasma dilution cross matched with donors’ RBC by microcolumn gel method. For a patient who was diagnosed as recurrent refractory MM and scheduled for blood transfusion, his blood was cross matched with donors’ blood by microcolumn gel method. 【Results】 1) Case 1 was a first-visit outpatient. The major side of microcolumn cross-match test was agglutinated with the shape of fine line. The result of tube method also showed agglutination of major sides, and the rouleaux were detected by the microscopy. Then polybrene method and microcolumn gel method (after plasma diluted) were applied for cross-matching again with the above two donors’ blood and showed compatibility. 2) Case 2 was a recurrent refractory MM patient. The major and minor sides of microcolumn cross-match test were both agglutinated with the shape of granular. The patient was treated with anti-CD38 monoclonal antibody. The RBCs, after treated with dithiothreitol (DTT) was used to cross match with patient plasma by microcolumn test, and the result was compatible. 【Conclusion】 Polybrene method and microcolumn gel method after plasma diluted are suitable for blood cross-matching of newly diagnosed MM patients, also for those treated with CD38 monoclonal antibody, as the drug interference with cross-matching can be eliminated by DTT.
