Hematopoietic stem cells (HSCs) reside at the top of the hierarchy and have the ability to differentiate to variety of hematopoietic progenitor cells (HPCs) or mature hematopoietic cells in each system. At present, the procress of HSC and HPC differentiating to the complete hematopoietic system under physiological and stressed conditions is poorly understood. In vivo lineage tracing is a powerful technique that can mark the individual cells and identify the differentiation pathways of their daughter cells, it takes as a strong technical system to research HSC.

Methods: POX tests and cardiac auscultation were used concurrently to screen 8305 neonates born in Jinjiang City Hospital between January 2016 and December 2018 for CHD. The positive screening results (positive POX or positive cardiac auscultation) were confirmed with echocardiography, while any false negative results were identified through follow-up and parent feedback.
Objective: The mobilization and collection of sufficient autologous peripheral blood stem cells (APBSCs) are important for the fast and sustained reconstruction of hematopoietic function after autologous transplantation. This study aims to evaluate the mobilization effect and safety of thrombopoietin (TPO) combined with chemotherapy + G-CSF for APBSCs in patients with refractory/relapsed non-Hodgkin's lymphoma.
Methods: A total of 78 patients were included in the present study.
Disease recurrence is the most important obstacle to achieve long-term survival for patients with advanced acute myeloid leukemia (AML) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). In order to reduce the relapse risk and improve the survival, the strategy of early tapering of immunosuppressive agents was prospectively evaluated. Thirty-one patients with advanced AML received early tapering of immunosuppressive drugs, while 32 patients with AML in complete remission (CR) were given the routine tapering of immunosuppressive agents after HLA-matched donor transplantation.

Objective: To evaluate the application of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) to the staging and detecting residual masses of lymphoma.
Methods: The clinical data of 179 patients with lymphoma were analyzed retrospectively. The results of FDG-PET, computed tomography (CT) and bone marrow biopsy (BMB) were compared for detection of lymph node/extranodal lymphoid tissue and bone marrow infiltration.
Objective: To evaluate the relationship of chimerism status of cell subsets with engraftment, occurrence of acute graft versus host disease (aGVHD), graft rejection and disease relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT).
Methods: Chimerism status in peripheral blood (PB) and bone marrow (BM) of 65 patients received allo-HSCT were monitored at regular intervals post-transplant. Fluorescence-activated cell sorter (FACS) was used to sort CD3(+)T lymphocytes in 65 cases, CD3(-)CD56(+)CD16(+)NK cells in 52 cases, CD15(+) granulocytes in 32 cases and CD19(+)B lymphocytes in 20 cases post transplants.

Objectives: Isovaleric acidemia (IVA) is an autosomal recessive inborn error of leucine metabolism caused by a deficiency of the mitochondrial enzyme isovaleryl-CoA dehydrogenase (IVD) resulting in the accumulation of derivatives of isovaleryl-CoA. IVA is considered to be a severe, potentially life-threatening disorder that manifests with acute neonatal encephalopathy in approximately half of affected individuals, and recurrent episodes of vomiting, lethargy, coma and varying degrees of developmental delay in the other half of patients. This study was conducted to investigate the clinical features and IVD gene mutations of a Chinese patient with IVA.

Objective: To explore the effect and possible mechanism of catechin microcapsulation on the repair of DNA damage in glumreular mesangial cells (GMCs) induced by H2O2.
Methods: According to H2O2 concentration, the experiment GMCs were divided into 6 groups: a control group, 50 micromol/L group, 100 micromol/L group, 150 micromol/L group, 200 micromol/L group and 250 micromol/L group. Each group was sub-divided into 3 groups: 6 h group, 12 h group and 24 h group, in order to determining the optimum dose and the best time of detecting the DNA damage in GMCs.
Background & Objective: The manifestations of old acute myelogenous (AML) patients have their special biological and clinical characteristics, with lower response rate to therapy and shorter survival time. This study was to investigate the prognostic factors of elderly patients with AML retrospectively.
Methods: 77 patients aged> or =60 years with AML from 1994 to 2005 were admitted to our study and all the possible prognostic factors were analyzed with Kaplan-Meier survival analysis.

Objective: The expressions of caspase-1 and cytokines activated by caspase-1 are associated with the pathophysiology of many diseases for its proinflammatory and proapototic peculiarity. However its relationship to brain injury of developing rats following recurrent seizures has not yet been identified. This study aimed to investigate the role of caspase-1 and cytokines activated by caspase-1 in brain injury of developing rats following recurrent seizures.

The response to GC treatment is an important indicator for the outcome of PNS children. Children with GC-resistant PNS present with incomplete or no response to GC, and may herald the progression to end-stage renal failure.
