Hodgkin lymphoma (HL) originates from the lymphoid hematopoietic tissues and has a good treatment outcome with relatively high cure rate.Early stage HL is curable with abbreviated chemotherapy plus involved-filed radiotherapy or chemotherapy alone.However,patients with refractory or relapsed disease still lack effective treatment.In recent years,with the application of risk stratified treatment,novel drugs such as brentuximad vedotin,and PET-CT evaluation,significant progress has been made in prognosis and treatment of HL

Aggressive B-cell lymphoma is characterized by malignant behaviour and rapid progression.Patients are prone to drug resistance or relapse of disease.The 19th European Hematology Association (EHA)annual congress explored several aspects about aggressive B-cell lymphoma.PET-CT examination provided new tools for the indication of prognosis.The elevated dose of rituximab improved the outcome of elderly male patients.Novel drugs or methods including bortezomib,ABT-199,combined targeted therapy and CNS prophylaxis have shown encouraging results in various clinical trials which provide new hope for patients with aggressive B-cell lymphoma.

Objective To investigate the angiogenic effect of leptin on grainy fat transplantation. Methods Grainy fat was obtained from the Wistar rat subcutaneous tissue in the abdomen. It was then mixed with 0.9 % NS and 20 ng/ml leptin and transplanted in the head subcutaneously. The transplanted tissue was taken out after 10, 20 and 40 days and was stained with AKP histochemistry and actin immunohistochemistry. The microvessel density was measured by medical imagine analysis system. The data were analyzed with SPSS software. Results The values of microvessel density in leptin groups were 0.12 ?0.04?m 2/?m 2 after 10 days and (6.83?1.86)?10 -2 ?m 2/?m 2 after 20 days. This was obviously high as compared with (1.49?0.88)?10 -2 ?m 2/?m 2 and (4.32?2.11)?10 -2 ?m 2/?m 2 in saline groups in the same observing periods ( P
