An adolescent with primary cutaneous follicle center lymphoma: a case report and literature review.

Primary cutaneous follicle center lymphoma (PCFCL) differs from follicular lymphoma in biological behavior and molecular profile and is treated as a distinct entity, according to the 5th edition of the World Health Organization classification of hematolymphoid tumors. It is an uncommon cutaneous B-cell lymphoma that is considerably rare in children and adolescents. To date, only 13 cases of individuals younger than 20 years of age have been reported in the literature.

Romiplostim in primary immune thrombocytopenia that is persistent or chronic: phase III multicenter, randomized, placebo-controlled clinical trial in China.

A multicentre retrospective study of primary breast diffuse large B-cell and high-grade B-cell lymphoma treatment strategies and survival.

Primary breast diffuse large B-cell lymphoma (PB-DLBCL) and primary breast high-grade B-cell lymphoma (PB-HGBCL) are rare extranodal aggressive B-cell lymphomas with distinct characteristics. Reliable data regarding appropriate treatment of these specific entities are lacking due to their rarity. We reviewed 36 patients diagnosed at four Chinese medical centres between January 2008 and December 2018.

Outcome of CARE: a 6-year national registry of acquired haemophilia A in China.

Acquired haemophilia A (AHA) is a rare haemorrhagic disorder caused by autoantibodies directed against the functional epitopes of coagulation factor VIII (FVIII). Its management relies on prompt diagnosis, control of bleeding and eradication of the inhibitor by immunosuppression. China Acquired Hemophilia Registry (CARE), a nationwide multicentre registry, was intended to survey the status of AHA and standardize its diagnosis and therapy in China.

At 0, 3, 6, 9, 12, 15 and 18 days after modeling, routine blood counts, bone marrow biopsy slides, lymphocyte subsets (CD4 and CD8 T cells) and cytokine levels [including interleukin (IL)-2, IL-4, IL-5 and interferon-γ] were assessed.

3D culture enhances chemoresistance of ALL Jurkat cell line by increasing DDR1 expression.

Three dimensional (3D) culture has gradually become a research hotspot in the field of drug screening, stem cell research, and tissue engineering due to its more physiological-like morphology and function. In this study, we compared the differences of cell proliferation, population, protein expression and chemoresistance profiles between two dimensional (2D) and 3D culture of acute lymphoblastic leukemia (ALL) Jurkat cell line. Polycaprolactone (PCL) is used for 3D culture owing to its biochemical properties and compatibility.

LncRNA FIRRE is activated by MYC and promotes the development of diffuse large B-cell lymphoma via Wnt/β-catenin signaling pathway.

Thirty-one patients received rhTPO at an initial dose of 300 U/kg once daily for 14 days.

Philadelphia chromosome-positive acute myeloid leukemia with masses and osteolytic lesions: finding of 18F-FDG PET/CT.

Philadelphia chromosome-positive acute myeloid leukemia is controversial and difficult to distinguish from the blast phase of chronic myeloid leukemia. As a myeloid neoplasm, rare cases of this leukemia manifest multiple soft-tissue tumors or bone lytic lesions. In this paper, we describe a 49-year-old male patient who had an abrupt onset with sharp chest pain, fever, fatigue, emaciation, and splenomegaly.
