[Breast cancer subtypes based on ER/PR and Her2 expression: comparison of MR imaging features].

Objective: To evaluate the magnetic resonance (MR) imaging findings of breast cancer subtypes based on the profiles of ER/PR and Her2.

Methods: A retrospective study was conducted for 267 breast cancer subjects between February 2007 and January 2011. Clinicopathologic features and MR imaging findings of four subtypes were compared.

[Clinicopathologic study on 61 cases of uterine papillary serous carcinoma with or without adjuvant therapy].

Objective: To study the clinicopathologic features of uterine papillary serous carcinoma (UPSC) and the roles of adjuvant therapy.

Methods: Sixty-one cases of UPSC with operation done and followed up for a period of 4 to 9 years were enrolled into the study. The histology of slides specimens were reviewed and immunohistochemical study was performed.

Features of intestinal T-cell lymphomas in Chinese population without evidence of celiac disease and their close association with Epstein-Barr virus infection.

Background: Intestinal T-cell lymphoma (ITCL) is a heterogeneous lymphoid neoplastic group with variable clinical and pathological features. ITCL in oriental countries is different from enteropathy-type intestinal T-cell lymphoma (ETCL) in relation to celiac disease and Epstein-Barr virus (EBV). The objective of this study was to investigate the clinicopathological features, immunophenotype, expression of cytotoxic molecule (TIA-1), T-cell receptor (TCR)-gamma gene rearrangement, and Epstein-Barr virus (EBV) latent infection in primary ITCL without celiac disease in Chinese.

Influence of N,N'-diacetyl-L-cystine on D-galactosamine/lipopolysaccharide induced immunological liver failure in mice.

Aim: To study the therapeutic effects of N,N'-diacetyl-L-cystine (DiNAC) on immunological liver failure.

Methods: Serum ALT, AST and T cell subsets in peripheral blood of the experimental animals during the trial period were analyzed by an automatic serum analyzer and a flow cytometer, respectively. The sectioned liver specimens were examined under a light microscope.
