Human umbilical cord-derived mesenchymal stromal cells for the treatment of steroid refractory grades III-IV acute graft-versus-host disease with long-term follow-up.

Introduction: Mesenchymal stromal cells (MSCs) have been extensively studied as a potential treatment for steroid refractory acute graft-versus-host disease (aGVHD). However, the majority of clinical trials have focused on bone marrow-derived MSCs.

Methods: In this study, we report the outcomes of 86 patients with grade III-IV (82.

[Efficacy and Safety of Allogeneic Hematopoietic Stem Cell Transplantation with Decitabine-containing Regimen in Myelodysplastic Syndromes and Myelodysplastic Syndromes Transformed Acute Myeloid Leukemia].

Objective: To evaluate the efficacy and safety of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with decitabine (Dec)-conditioning regimen in the treatment of myelodysplastic syndrome (MDS) and MDS transformed acute myeloid leukemia (MDS-AML).

Methods: The characteristics and efficacy data of 93 patients with MDS and MDS-AML who received allo-HSCT in our center from April 2013 to November 2021 were retrospectively analyzed. All patients were administered by myeloablative conditioning regimen containing Dec (25 mg/m /d×3 d).

Allogeneic haematopoietic stem cell transplantation with decitabine-containing preconditioning regimen in TP53-mutant myelodysplastic syndromes: A case study.

Myelodysplastic syndrome (MDS) with TP53 mutations has a poor prognosis after transplantation, and novel therapeutic means are urgently needed. Decitabine (Dec) monotherapy has demonstrated improved overall response rates in MDS and acute myeloid leukaemia, although these responses were not durable. This study aimed to preliminary evaluate the efficacy of a Dec-containing allogeneic haematopoietic stem cell transplantation (allo-HSCT) preconditioning regimen in TP53-mutant MDS.

CD19 CAR-T Cells With Membrane-Bound IL-15 for B-Cell Acute Lymphoblastic Leukemia After Failure of CD19 and CD22 CAR-T Cells: Case Report.

Objectives: At present, reinfusions of chimeric antigen receptor (CAR)-T cell have exhibited limited efficacy, while their efficacy on extramedullary relapse remains to be further elucidated in B-cell acute lymphoblastic leukemia (B-ALL). Although combination with IL-15 demonstrated the potential to enhance antitumor activity of CAR-T, the efficacy of this approach remains to be validated clinically.

Methods: We reported a patient with B-ALL with extramedullary relapse after allogeneic stem cell transplantation and who was resistant to chemotherapy and radiotherapy.

[Relationship between NK Cell Reconstitution and aGVHD after Allo-HSCT].

Objective: To investigate the relationship between NK cell count/activity and acute graft-versus-host disease (aGVHD) in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: A total of 26 patients who had undergone allo-HSCT from January to July 2015 were enrolled in this study. The NK cell count/activity in the peripheral blood of recipients on day 30 after allo-HSCT were monitored by using 4-color flow cytometry.

[Analysis of Risk Factors for Cytomegalovirus Infection after Allogeneic Hematopoietic Stem Cell Transplantation].

Objective: To analyze the incidence of cytomegalovirus infection and related risk factors after allogeneic hematopoietic cell transplantation and to develop a rational strategy for the preemptive treatment of CMV infection.

Methods: The clinical data of 398 patients undergoing allogeneic hematopoietic cell transplantation from December 2011 to December 2014 were analyzed retrospectively by using a Kaplan Meier analysis and Logistics model.

Results: Out of 398 patients 233 developed post-transplant CMV infection (58.

Different dosages of intravenous immunoglobulin (IVIg) in treating immune thrombocytopenia with long-term follow-up of three years: Results of a prospective study including 167 cases.

This study compared the effects of different dosages of intravenous immunoglobulin (IVIg) against immune thrombocytopenia (ITP). A total of 167 patients, 91 adults and 76 children, with ITP, followed-up for three years in the case-control study, were divided into three subgroups according to the dosages of IVIg administered: group A (0.2 g/kg/day), group B (0.

Analysis of possible factors relating to prognosis in autologous peripheral blood mononuclear cell transplantation for critical limb ischemia.

Background Aims: Autologous transplantation of granulocyte colony-stimulating factor-mobilized peripheral blood mononuclear cells (M-PBMNCs) has been shown to be effective in treating critical limb ischemia (CLI); however, the studies of the possible prognosis predictors after autologous M-PBMNC transplantation are inadequate. The objective of the study was to assess the possible factors affecting the results of M-PBMNC transplantation for CLI.

Methods: We reviewed the clinical profiles of 87 patients with CLI who were treated with M-PBMNC implantation in the Blood Diseases Hospital, Chinese Academy of Medical Sciences, between December 2002 and December 2011, and we followed these patients.
