Objective To study the biological features and prognostic factors of mantle ceil lymphoma (MCL).Methods The clinical data of 39 cases of MCL were analyzed prospectively.The fellow-up informations were also studied.Age,sex,B symptoms,Ann-Arbor staging,bone marrow and lympho node biopsies were assessed.Serum lactate dehydrogenates(LDH) and β2-microglobulin (β2-MG) level,Cyclin D1 expression and immunophenotype were investigated.Results The median age of patients was 62 years old (range 43-80).The male-to-female ratio was 5.5:1,a clear predominante of male patients.Thirty-five (89.7 ％)cases presented with advanced stage disease (Ann Arbor stage Ⅲ to Ⅳ) at initial diagnosis.CD20 was positive expressed in 39 patients,that all cases expressed B-cell markers.Majority of cases were positive for Cyclin D1 (84.7 ％) and CD5 (64.1％).Conclusion MCL is a special type of B-cell originated non-Hodgkin lymphoma (NHL).The clinical data suggest considerable clinical heterogeneity and it has characteristics of both indolent and aggressive NHL that some patients show a chronic/indolent course,while others have a more fulminant course and short survival.LDH,β2-MG and Cyclin D1 arc the important prognostic factors.

A growing body of evidence demonstrates that vascular factors have involved in the occurrence and development of Alzheimer's disease.This article reviews the research progress of the AD-associated vascular factors from the aspects of AD epidemiology,pathology,clinical research,imaging,and genetics,expecting to investigate the nature of AD from all aspects through vascular factors and finding a new entry point for prevention,diagnosis and treatment of AD.
