The chimeric antigen receptor (CAR) T cell therapy has gradually became a new trend in the treatment of refractory and relapsed hematologic malignancies by developing for 30 years. With the exciting development of genetic engineering, CAR-T technology has subjected to 4 generations of innovation. Structure of CAR-T started from a single signal molecule to 2 or more than 2 co-stimulatory molecules, and then coding the CAR gene or promoter. CAR-T can specifically recognize tumor antigens, and does not be restricted by major histocompatibility complex (MHC), thus making a breakthrough in clinical treatment...

Xiao-Yang Yang, Meng-Jie Wan, Fang-Ping Chen
Since the American Medical Association published the 2011 guidelines for immune thrombocytopenia, China has been the first to update the guidelines for immune thrombocytopenia based on evidence-based medicine. Recently, there have been many breakthroughs in clinical research published, especially the Chinese medical workers have made a prominent contribution to the treatment of the immune thrombocytopenia. However, the references of systematic drug introduction for children, adults, aged and pregnant women are still insufficient, and the first or second line treatment for some patients were ineffective...

It has been increasingly recognized that the pathogenesis of B-cell lymphoma closely relates to the epigenetic disregulations. Epigenetics is a subdiscipline, which means heritable changes in gene expressions without alterations in the DNA sequence, and the DNA methylation, histone modification and miRNA maily were involved. Histone modification is the most important epigenetic modification, the researches showed that the aberrant histone modification is the important pathogenesis in B-cell lymphoma, especially the aberrant histone methylation and acetylation...

Diffuse large B-cell lymphoma (DLBCL) accounts for approximately 30% of the non-Hodgkin's lymphoma patients. The underlying molecular mechanism of its pathogenesis is not well defined and the survival rate of DLBCL patients is very low. Moreover, the annual incidence and mortality of DLBCL is still rising. Accordingly, identification and characterization of new molecular pathways of DLBCL will lead to the development of novel diagnostic markers and molecular therapeutic targets. Long non-coding RNAs (LncRNA) are non-coding RNAs with a length greater than 200 bp in eukaryotic cells, which can regulate the expression of their target genes at the transcriptional and post transcriptional levels...

Diffuse large B-cell lymphoma (DLBCL) is biologically aggressive and most common pathological type of non-Hodgkin's lymphoma (NHL), and about one-third of these patients are refractory or relapsed ultimately. Based on the molecular heterogeneity, DLBCL can be divided into 3 main molecular subtypes: germinal center B-cell like (GCB), activated B-cell like (ABC) and primary mediastinal B-cell lymphoma (PMBL). Arising from B cells at distinct stages of differentiation, these subtypes are also diverse in mechanisms of oncogenic activation...

β-catenin is an important member of Wnt signaling pathway. With more and more research on the relationship between β-catenin and cancers, it is noted that the concentration of β-catenin in cells is not only the landmark of activating the Wnt signaling pathway, but also a common phenomenon in various tumor cells. Moreover, abnormal expression of β-catenin is reported in blastic phase of CML and IM-resistant CML. Besides, β-catenin inhibitor is proved to be effective for the improvement of the IM susceptibility and the postponment of blastic phase...

Myeloproliferative neoplasm(MPN) is clonal hematopoietic stem cell disorder characterized by abnormal proliferation and expansion of one or more myeloid lineages. BCR-ABL-negative MPN includes polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (PMF). The mutations of JAK2, CALR and MPL genes are involved in the pathogenesis of MPN that provided a more complete molecular diagnostic standard for MPN. More and more new mutated genes related to prognosis of MPN were discovered in the past few years, at same time it was found that cytokines were also involved in the genesis and development of MPN...
