Extranodal natural killer/T cell lymphoma (ENKTL) is an EBV-associated and highly aggressive subtype of non-Hodgkin lymphoma. Most patients are distributed in Asia and South America, and advanced-stage patients have poor prognosis. Reports on research progress of ENKTL in the 58th American Society of Hematology Annual Meeting covered multiple respects which range from basic research to clinical prognosis and treatment: further study on pathogenesis of ENKTL is developing based on high-throughput sequence, and new prognostic index system can help to stratify patients more exactly; what's more, novel regimens make more benefits to the clinical efficacy and safety of ENKTL patients.

Chronic lymphocytic leukemia (CLL) is a chronic B-cell lymphoproliferative clonal disease with a highly heterogeneous clinical course. In recent years, with the emerging of immunochemotherapy, bcl-2 inhibitor, B-cell receptor signal transduction kinase inhibitors and the chimeric antigen receptor-T cell (CAR-T), more and more improvements were made in CLL therapy and remission. This report addressed the progress of CLL therapy in the 57th American Society of Hematology annual meeting.

Objective To determine the biological effect of p27 KIP1 on gastric carcinoma cells SGC7901. Methods The total length of p27 KIP1 cDNA was transfected into human gastric cancer cells SGC7901 by lipofectin transfection. Expression of p27 KIP1 in protein or mRNA level was examined by Western blotting and RNA dot blotting respectively. Effect of p27 KIP1 on cell growth was observed by trpan blue exclusion assay. Tumorigenicity test in nude mice was applied to assess the biological effect of p27 KIP1 in vitro. Results Expression of p27 KIP1 in protein or mRNA increased evidently in SGC7901 cells transfected with p27 KIP1 . The cell growth was reduced by 42% about 48h after the induction with Zn 2+ ,which was determined by cell viability assay. The tumorigenicity of nude mice was reduced evidently(P

Objective To evaluate the significance of dual-color interphase fluorescence in situ hybridization (FISH) in the engraftment estimation and minimal residual disease (MRD) monitoring after sex-mismatched allogeneic hematopoietic stem cell transplantation (allo-HSCT).Method The fluorescence signal of samples from 35 cases in different periods after sex-mismatched allo-HSCT were detected by interphase FISH using chromosome enumeration probes (CEP) X and Y. Results All of 35 patients had been determined to obtain engraftment after allo-HSCT. When the disease relapsed,FISH showed that the percentage of donor chromosomes was decreased and when the disease got remission,the percentage of donor chromosomes increased. When conventional cytogenetics showed 100 % XX or 100 % XY,FISH showed different percentage of host chromosomes.Conclusions The test of dual-color interphase FISH is reliably sensitive and simple for engraftment evaluation and MRD monitoring post HSCT. It is a good complement method to cell morphology and traditional karyotype analysis.

Objective To investigate the efficacy and safety of tirofiban in acute coronary syndrome(ACS)patients during primary PCI.Methods Sixty two patients with ACS who underwent primary PCI were randomly divided into two groups which were:the tirofiban + PCI group(n=32)and the primary PCI group(n=30).Tirofiban was predominantly initiated in the catheter laboratory before or during the intervention and maintained for a mean of 30 h(10 ?g/kg for bolus,followed by 0.15 ?g/kg?min infusion).Platelet counting,MACE event and periprocedural complication were investigated.Heart function by echo was observed.Results The incidence of the major primary end point(refractory ischemia,new myocardial infarction and death)at 30 days was significantly lower in the tirofiban group than that in the placebo group(9.3% vs 20.0%,P

Follicular lymphoma (FL) is a kind of indolent non-Hodgkin lymphoma (iNHL), which origins from follicle germinal center. Multiple researches reported the latest development about treatment of FL in the 58th American Society of Hematology (ASH) Annual Meeting. The outcomes of clinical trials in which GAl01 combined with chemotherapy and bendamustine in combination with 90Y-ibritumomab tiuxetan for the advanced stage FL were exciting. Relapsed/refractory FL patients who receive tandem autologous followed by nonmyeloablative allogeneic transplantation could acquire preferable remissions. With the emerging of novel drugs including inhibitor of bcl-2 or PI3K and antibody drug conjugate, more and more improvements of efficacy and remission were made in the treatment of relapsed/refractory FL therapy and remission.

Positron emission tomography-computed tomography (PET-CT) with both anatomic and functional information is now widely utilized for most lymphoma subtypes,among which,the pretreatment staging and response assessment of PET-CT in Hodgkin lymphoma (HL) and diffuse large B-cell lymphoma (DLBCL)have been well documented.Multiple clinical trials are ongoing using PET-CT for therapy monitoring.Additionally,factors interpreting interim PET (PET-i) like visual analysis using Deauville 5-PS,metabolic tumor volume at baseline (MTV0),and △ SUVmaxPET0-i show different prognostic values.However,the management of PET-CT in lymphoma is still elusive,further trials remain to be done to get evidences for the use of PET-CT in guiding therapeutic decisions.

Objective:To investigate the possibility of producing vaccine with higher effect of anti-hepatoma by means of freezing the tumour cells which have been modified by TNF-? genes before. Methods: H22 cells which had been modified by TNF-? genes were treated by means of freezing and 60Co radiation or of 60Co radiation, respectively. Then, they were put to use to produce two kinds of vaccines. Effects of these two kinds of vaccines on anti- plant-hepatoma in mice were compared. Results: Effects of increasing the inhibiting rates, the levels of lectin-induced IL-2 and TNF from splenocytes, and the splentic NK activity, were all obviously seen stronger in vaccine made up of cells treated by the method combined with freezing, than that in vaccine made up of cells by no freezing. Conclusion: Method of freezing, after procedure of TNF-a gene modifying, could raise up the immunogenicity of the tumour cells, thereby enhance the anti-plant-hepatoma effect in mice induced by the vaccine.

The role of consolidating radiation therapy (RT) is very controversial in Hodgkin lymphoma (HL),especially in adolescents and young adults (AYA) HL.The key problem is how to achieve better therapeutic effect but bear less toxicities in chemotherapy and radiotherapy,which will be hopefully solved by clinical trials adopting interim positron emission tomography (iPET) scanning to guide therapy for HL.The new technologies including whole genome amplification (WGA),high-throughput gene sequencing (NGS) assay and genome-wide association study (GWAS) further illustrate abnormal signaling pathways in HL,such as NF-κB,JAK/STAT and PI3K pathway,which may provide new therapeutic targets for the disease.
