Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer, with an overall prevalence of 4/100,000, accounting for 25-30% of all childhood cancers. With advances in childhood ALL treatment, the cure rate for childhood ALL has exceeded 80% in most countries. However, refractory/relapsed ALL remains a leading cause of treatment failure and subsequent death.

Secondary acute myeloid leukemia (sAML) is a high-risk AML evolving from heterogenous prior hematological disorders. Compared to de novo AML, sAML has even worse responses to current therapy and thus is associated with lower remission rates, inferior overall survival (OS) and higher relapse rates. Many efforts have been devoted to improving the overall but with limited success, and novel strategy is thus highly needed.

The ability to identify a specific type of leukemia using minimally invasive biopsies holds great promise to improve the diagnosis, treatment selection, and prognosis prediction of patients. Using genome-wide methylation profiling and machine learning methods, we investigated the utility of CpG methylation status to differentiate blood from patients with acute lymphocytic leukemia (ALL) or acute myelogenous leukemia (AML) from normal blood. We established a CpG methylation panel that can distinguish ALL and AML blood from normal blood as well as ALL blood from AML blood with high sensitivity and specificity.

Introduction: Post-transplant lymphoproliferative disorder (PTLD) is the most common form of lymphoproliferation in childhood and is associated with significant morbidity and mortality. In this report we reviewed the case of a pediatric patient who experienced PTLD after allogeneic hematopoietic stem cell transplantation (HSCT) from a human leukocyte antigen (HLA)-identical sibling.

Methods: The clinical characteristics, diagnosis, and treatment of PTLD after sibling HSCT in a 4-year-old boy with severe β-thalassemia was retrospectively reviewed.

Unlabelled: To reveal the formation mechanism of a pulse-jet airflow's cleaning effect in a filter bag, a theoretical model is built by using the theory of the gas jet and unitary adiabatic flow according to given specifications and dimensions of the bags and resistance characteristics of the cloth and dust layer. It is about the relationship between cleaning system structure and operating parameters. The model follows the principle that the flow and kinetic energy of jet flow injected into a filter bag should be consistent with the flow of cleaning airflow in the bag and the pressure drop flowing through the filter cloth and dust layer.

Objective: To observe the status of iron deposition in patient with β thalassemia major, and to formulate appropriate treatment strategies.

Method: The data of status of transfusion and chelation in 135 patients aged from 6 years and 4 months to 17 years and 11 months with β thalassemia major were collected and analyzed. Serum ferritin levels were determined and cardiac and hepatic iron deposition was determined using MRI T2(*) technology.

Objective: To study the influence of cord blood total nucleated cell (TNC) dose on the efficacy of cord blood transplantation in children.

Methods: Thirty-four children with hematological disease received cord blood transplantation. They were assigned to 3 groups according to the infused TNC dose: TNC>10 x 10(7)/kg (n=7), 10 x10(7)/kg>TNC> or =7 x 10(7)/kg (n=9) and TNC<7 x 10(7)/kg (n=18).

Objective: Hematopoietic stem cell transplantation is currently a unique curative therapy for beta-thalassemia major. However, only 30% of patients have HLA-identical siblings to serve as donors. This study investigated the feasibility of hematopoietic stem cell transplantation from HLA mismatched related donors for beta-thalassemia major in children.

Objective: To analyze the relationship between cell-mediated immune function during conditioning and graft rejection in patients with beta-thalassemia major.

Methods: Allogeneic hematopoietic stem cell transplantation was performed in 25 children with beta-thalassemia major and 11 with acute leukemia group. The percentages of T lymphocytes and natural killer (NK) cells in peripheral blood of these patients were detected with dual color immunofluorescence on day -10 (before conditioning) and day -5 (after conditioning), and the relationship between the cellular immune function and graft rejection was analyzed.

Objective: To study the status of growth and development and the relationship between growth disorders and iron overload in children with beta-thalassemia major.

Methods: Fifty children with beta-thalassemia major and who received blood transfusion therapy regularly (age: 9 months-17 years) were enrolled. They were subjected to a thorough history taking, clinical examinations, and laboratory examinations, including complete blood count, alanine transferasa (ALT) and serum ferritin.

The objective of this study was to investigate the curative effect of combined sibling umbilical cord blood and bone marrow transplantation in treatment of beta-thalassemia major. Combined umbilical cord blood and bone marrow transplantation from an HLA-identical sibling were performed for 3 patients with beta-thalassemia major. The nucleated cells infused into 3 recipients were 19.

Objective: Hepatic veno-occlusive disease (HVOD) is one of the most serious complications after allogenic hematopoietic stem cell transplantation (allo-SCT). Endothelial injury, leading to deposition of coagulation factors in the terminal hepatic venules, is believed to the key event in the pathogenesis of HVOD. This study was designed to explore the efficacy of low-dose heparin and prostaglandin E1 (PGE1) in the prevention of HVOD after allo-SCT in children with beta-thalassemia major.

Allogeneic hematopoietic stem cell transplantation is the only curative therapy for severe beta-thalassemia. This time, the experience of utilizing HLA 2-loci mismatched sibling cord blood transplantation (CBT) in a child with severe beta-thalassemia was firstly reported in our country. A 3-year-male patient had been diagnosed with severe beta-thalassemia at 6 months of age (HbF 86.
