Objective: To clarify clinical and morphological features and immunophenotype of T lymphoblastic lymphoma/leukaemia (T-LBL/ALL) and to further improve the knowledge and diagnostic accuracy for T-ALL/LBL.

Methods: 128 cases of T-LBL/ALL were analyzed for the clinical features, morphology, immunophenotype and TCR gene rearrangement using routine eosin and haematoxylin stain, immunohistochemistry and polymerase chain reaction combining with the clinical findings.

Results: In 128 cases of T-LBL/ALL, there were 94 male and 34 female.

ING4, a new member of the ING (inhibitor of growth) family of tumour suppressor genes, has been found to be deleted or down-regulated in gliomas, breast tumours, and head and neck squamous cell carcinomas. The goal of the present study was to investigate whether the expression and alternative splicing of ING4 transcripts are involved in the initiation and progression of stomach adenocarcinoma. ING4 mRNA and protein expression was examined in gastric adenocarcinoma tissues and human gastric adenocarcinoma cell lines by RT-PCR, real-time RT-PCR, tissue microarray immunohistochemistry, and western blot analysis.

Ceruloplasmin (CP) is essential for brain iron homeostasis. However, little is known about the effect of iron on CP expression in the brain. Also, the role of CP in brain iron transport has not been well determined.

The increased iron content in the brain of subjects with aceruloplasminemia has implicated ceruloplasmin (CP) as a major factor in the regulation of regional brain iron content. In this study, we investigated the effects of age and iron on CP expression in rat brain. In all four regions, the iron concentrations increased with developmental age.

The DMT1(Nramp2/DCT1) is a newly discovered proton-coupled metal-ion transport protein. The cellular localization and functional characterization of DMT1 suggest that it might play a role in physiological iron transport in the brain. In the study, we evaluated effects of dietary iron and age on iron content and DMT1 expression in four brain regions: cortex, hippocampus, striatum, substantia nigra.

Aim: To observe the relationship between the expression of vascular endothelial growth factor (VEGF), microvascular density (MVD) and the pathological characteristics of esophageal and gastric carcinomas.

Methods: S-P immunohistochemical staining was used to investigate the expression of VEGF in all the specimens. The antibody against factor VIII-related antigen was used to display vascular endothelial cells, and MVD was examined by counting the factor VIII-positive vascular endothelial cells.
