[Gastrointestinal B-cell lymphoma: a morphologic and immunohistochemical study of 194 cases].

Objective: To study the morphologic and immunohistochemical features of gastrointestinal B-cell lymphomas.

Methods: One hundred and ninety-four cases of gastrointestinal B-cell lymphoma were retrieved from the archival file. The clinical features and pathologic findings were reviewed.

[Expression and clinical significance of phosphatidylinositol 3-kinase and protein kinase B in cervical carcinoma].

Background & Objective: Phosphatidylinositol 3-kinase /protein kinase B (PI3K/Akt) signaling pathway is involved in a variety of important cellular functions, including genesis and progression of neoplasms. However, its role in cervical cancer is unclear. This study was to detect the expression of PI3K and Akt proteins in different cervical lesions, and to investigate the correlation of PI3K/Akt signal transduction pathway to biological behaviors of cervical carcinoma.
