Although the application of combined chemotherapy has made a great progress in treatment of adult acute myeloid leukemia (AML), the overall survival rate is still not high, mainly because of high recurrence rate and drug resistance. The treatment regimen for relapsed/refractory AML is always strong. Due to the chemotherapy drugs lacking of specific identification of tumor cells, significant adverse reactions often come out and sometimes even endanger the life of patients. In order to improve the life quality and survival rate, the new treatment strategy is urgently needed...

The myelodysplastic syndromes (MDS) are a heterogeneous group of clonal myeloid disorders characterized by ineffective hematopoiesis and increased risk of transformation to acute myelogenous leukemia (AML). The treatment of MDS is highly dependent on the reliability of the prognostic evaluation model. Current clinical prognostic scoring systems are comprised of morphology, pivotal clinical trials and cytogenetic findings. However, none of the available prognostic systems incorporates disease-related molecular abnormalities, such as somatic mutations...

Cytogenetic abnormalities get wide attention for its guidance value for prognosis and therapy in myelodysplastic syndrome (MDS) and related malignancies. Cytogenetic analysis is also the key to clarify the molecular pathogenesis of these kinds of diseases. The traditional karyotyping technique including metaphase cytogenetic (MC) karyotype analysis and immune fluorescence in situ hybridization (FISH) can detect the chromosomal abnormalities to some degree while the positive rate detected by the techniques is low due to the low resolution, dependence on metaphase dividing cells or the limitation of specific sites on the chromosomes, respectively...

Cereblon(CRBN) is a brain-associated protein with ionic protease activity, which interacts with DNA damage-binding protein-1 (DDB1), Cullin 4 (Cul4A or Cul4B), and regulator of Cullins 1 (RoC1) to form the functional E3 ubiquitin ligase complex(CRBN-CRL4) that performs proteolysis via the ubiquitin-proteasome pathway. And CRBN is a necessary target protein for the anti-myeloma effect of immunomodulators. The combination of lenalidomide and CRBN recruited a new substrate that binds to the CRBN-CRL4 complex, leading to increased ubiquitination and proteasome-dependent degradation, thus resulting in anti-myeloma activity...

Thrombotic thrombocytopenic purpura (TTP) is an acute, potentially life-threatening thrombotic microangiopathies (TMA). TTP has mainly been diagnosed by clinical findings, such as thrombocytopenia and microangiopathic haemolytic anemia. In addition, the reduced activity of von Willebrand factor-cleaving metalloproteinase ADAMTS13 below 10% has been accepted internationally as a diagnostic criterion for TTP. In clinic, the accurate diagnosis and early initiation of therapy can significantly improve the survival rate of patients...

POEMS syndrome is a rare multiple organ involvement of the parasympathetic syndrome associated with abnormal plasma cells, mostly with high-dose chemotherapy and stem cell transplantation for the treatment. Recently, more treatment attempts to treat POEMS syndrome have been utilized so as to improve the efficacy and safety for the patients with POEMS syndrome, such as immunomodulator, alkylating agent, cytokine-induced killer cells and so on. Lenalidomide has a significant effect on relapse/refractory POEMS syndrome and patients with endocrinopathy...

Hematopoietic stem cells (HSC) maintain homeostatic hematopoiesis via their multi-lineage differentiation and self-renewal potentials. HSC can be enriched and purified by flow cytometry relying on their cell surface markers and functional characteristics, however, these methods can not meet the need for deep analysis of HSC biological property and function because of the poor purity. Recent studies have successfully purified and tracked HSC using specifically expressed genes, which can enhance the purification efficiency of HSC, thus provide a better tool for the in-vivo study of HSC...
