Fang-Lin Li, Ai-Fei Liu, Yi-Jian Chen
Previous studies have found that Musashi-2 (Msi-2) plays an essential role in regulating the gene expression of stem cell populations by inhibiting or activating the translation, and thus regulates stem cell function. Current research shows that Msi-2 involved in the regulation of a variety of malignant hematological diseases through different mechanisms; moreover abnormally expressed in a variety of malignant hematological diseases and involved in the occurrence, development of a variety of malignant hematological diseases...

Yan Li, Li Yu
Invasive fungal diseases (IFD) are associated with considerable morbidity and mortality in patients with hematological malignancies. Primary antifungal prophylaxis (PAP) is effective for decreasing incidence of IFD, and the patients will be more tolerable to chemotherapy with less cost and better prognosis. Antifungal drugs as fluconazole, itraconazole, posaconazole, caspofungin and micafungin are all recommended for PAP by many consensus and guidelines. The PAP will be more scientific, appropriate and effective with the development of studies about predicting risk-stratification for IFD, new drugs, pharmacokinetics and integrated prophylaxis...

Xie Su, Peng Cheng, Dong-Hong Deng
Microparticles (MP) are small membrane vesicles released from many different cell types in response to cellular activation or apoptosis, which have the procoagulant effect. Hemolytic anemia(HA) is a type of anemia that have a short life expectancy of red blood cells due to the destruction which exceed the hematopoietic compensatory capacity of bone marrow. Sickle cell anemia(SCD), thalassemia and paroxysmal nocturnal hemoglobinuria(PNH) are all characterized by hypercoagulation and thromboembolism (TE). Research shows that MP can promote the formation of hypercoagulative state which in turn increases the risk of thromboembolism in HA...

Lin Li, Zhi-Jian Xiao, Xue-Mei Sun
The spectrum of genetic abnormalities in myelodysplastic syndromes(MDS) has been revealed by high-throughput sequencing. However, the functional role of these mutations in occurrence and development of MDS was not delineated. The mutations in splicing factors have been identified as the commonest gene mutations in MDS. Recently, it was reported that the mutated or dysregulated splicing factors, including SF3B1, SRSF2 and U2AF1, attribute to aberrant mRNA splicing, which leads to hematopoietic dysfunction and drives MDS...

Myeloma nephropathy is a common complication in patients with myltiple myeloma (MM) that causes high morbidity. In the majority of cases, renal impairment is caused by the accumulation and precipitation of light chains, which form casts in the distal tubules, resulting in renal obstruction. This review discusses the recent advances on its treatment, so as to provide reference for clinical treatment of MM induced-renal failure.

Drug resistance of multiple myeloma(MM) has become more and more common, and greatly decreased the survival rate of these patients. The occurence of drug-resistance involves in many factors such as bone marrow microenveronment, tumor cell self-metabolism, cytokines, specific targets and so on. In this review, the potential mechanisms of resistance to glucocorticoid/proteasome inhibitor/immunomodulatory druges are briefly expounded in the aspect of tumor cell self-metabolism, including the changes of heat slock protein expression, mRNA expression, related cytokine levels and down-regulation of thalidomid-effecting site CRBN expression...

Primary breast lymphoma(PBL) is a rare and unique type of lymphoma. Female patients are the majority, but its pathogenesis is not clear, and the estrogen may be related with the pathoganesis. Women who have breast implants have more chance to be suffered. The painless breast masses are the most common clinical manifestations, which is similar to breast cancer. Surgical resection of the mass and core needle biopsy are helpful for the diagnosis. The most common pathological type of PBL is diffuse large B cell type, with non GCB type, and it is prone to extranodal relapse in which central nervous system relapse is common which has poor prognosis...

Splenic marginal zone lymphoma (SMZL) is an uncommon indolent B-cell non-Hodgkin's lymphoma. The clinical features of SMZL are splenomegaly, lymphocytosis and cytopenia in peripheral blood. Immunopheno-typically, the neoplastic cells are typically positive for CD45, CD20, CD79a, PAX5, IgD, BCL-2. The previous common used treatment is splenectomy and chemotherapy. Nowadays, rituximab-based chemotherapy regimens has improved the curative effect dramaticlly. IFN-α with or without ribavirin can be used to treat the patients with HCV infection...

Qian Wang, Yu-Feng Li
Homoharringtonine(HHT) is an alkaloid with anti-tumor activity, having a good therapeutic effect on chronic myeloid leukemia(CML), and its toxicity is much lower than other anti-cancer drugs. However, the remarkable therapeutic efficacy of imatinib on CML treatment made HHT to be forgotten gradually. Today, the omacetaxine mepesuccinate, a semisynthetic form of HHT, display a good clinical response to TKI-resistant CML patients. Therefore, the HHT again attracts more attention from the medical field. Here, the clinical effects of HHT on IM-resistant CML patients and its mechanism are briefly reviewed...

Lymphocyte function-associated antigen-3 (LFA-3/CD58) is a cell-surface glycoprotein, it can bind to CD2 and activate the costimulation pathways of T lymphocytes and natural killer (NK) cells, maximizing the cytolysis of target cells by cytotoxic T lymphocytes (CTL) and NK cells. Some studies have demonstrated that in acute lymphoblastic leukemia(ALL) and lymphomas, lack of CD58 on the tumor cells may fail to activate the T lymphocytes and NK cells, resulting in feeble cytotoxic effect and subsequently escape from immune surveillance, making the disease become more complicated and liable to relapse...

T lymphoblastic lymphoma / leukemia is a strong invasive and has a high incidence of various molecular genetic abnormalities. The NOTCH1 / FBXW7 mutation is one of the most common mutations, and related with good prognosis in T-LBL / ALL. PTEN mutation, a poor prognostic factor, could be overcome by NOTCH1 mutations in pediatric patients to some extent. Patients with MLL gene abnormality and loss of heterozygosity 6q have worse prognosis than those with normal karyotype. The incidence of MLL gene abnormality, RUNX1 mutation and DNMT3A mutation in early precursor T-lymphoblastic leukemia was higher than that of other mature subtypes, which could be used as risk stratification factors...
