Objective: To analyze the incidence of bone marrow involvement in patients with different pathological types of lymphoma.
Methods: The results of bone marrow tests including bone marrow aspiration(BMA), flow cytometry detection, bone marrow biopsy(BMB) and F-FDG PET/CT, were analyzed retrospectively in 702 cases of newly diagnosed lymphoma with bone marrow assessment in our hospital from October 2000 to September 2016. If one of the above-mentioned 4 tests showed positive, the lymphoma patient was judged as bone marrow involved.
Results: The incidence of bone marrow involvement (BMI ) in the patients with NHL was much higher than that in patients with HL [32.6 %(201/616) vs 15%(13/86)](P<0.05). For patients with NHL, the incidence of bone marrow involvement in B-cell lymphoma was higher than that in T-cell lymphoma (37.0% vs 22.6%)(P<0.05). According to different pathological types, the incidences of BMI in the patient with mantle cell lymphoma, hepatosplenic T-cell lymphoma, diffuse large B-cell lymphoma (DLBCL) and follical lymphoma (FL) were 88% (25/22), 100% (5/5), 21.8% (56/257), and 38.5% (15/39) , respectively.
Conclusion: The incidence of bone marrow involvement varies in different pathological types of lymphoma.Bone marrow assessment has significant importance for stading of newly diagnosed lymphoma patients.

Leukemia symptoms occurring in the first 4 weeks of infancy are known as congenital leukemia. We present a case of congenital leukemia in a full-term neonate manifesting at birth with a grossly distended abdomen due to a large abdominal mass. Ultrasonography of the abdomen showed a large abdominal mass originating from the liver.

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by reduced platelet levels and heightened susceptibility to bleeding resulting from augmented autologous platelet destruction and diminished thrombopoiesis. Although antibody-mediated autoimmune reactions are widely recognized as primary factors, the precise etiological agents that trigger ITP remain unidentified. The pathogenesis of ITP remains unclear owing to the absence of comprehensive high-throughput data, except for the belated emergence of autoreactive antibodies.

Creatine is essential for ATP regeneration in energy-demanding cells. Creatine deficiency results in severe neurodevelopmental impairments. In the brain, creatine is synthesized locally by oligodendrocytes to supply neighboring neurons.

Background: Long-term renal allograft acceptance has been achieved in macaques using a transient mixed hematopoetic chimerism protocol, but similar regimens have proven unsuccessful in heart allograft recipients unless a kidney transplant was performed simultaneously. Here, we test whether a modified protocol based on targeting CD154, CD2, and CD28 is sufficient to prolong heart allograft acceptance or promote the expansion of regulatory T cells.
Methods: Eight macaques underwent heterotopic allo-heart transplantation from major histocompatibility complex-mismatched donors.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is one of the most important methods for treating a wide range of hematologic malignancies and bone marrow failure diseases. However, graft-versus-host disease (GVHD), a major complication associated with this method, can seriously affect the survival and quality of life of patients. Acute GVHD (aGVHD) occurs within 100 days after transplantation, and gastrointestinal aGVHD (GI-aGVHD) is one of the leading causes of nonrecurrent death after allo-HSCT.
