Three-dimensional visualization and evaluation of hilar cholangiocarcinoma resectability and proposal of a new classification.

Background: As digital medicine has exerted profound influences upon diagnosis and treatment of hepatobiliary diseases, our study aims to investigate the accuracy of three-dimensional visualization and evaluation (3DVE) system in assessing the resectability of hilar cholangiocarcinoma (hCCA), and explores its potential clinical value.

Materials And Methods: The discovery cohort, containing 111 patients from April 2013 to December 2019, was retrospectively included to determine resectability according to revised criteria for unresectability of hCCA. 3D visualization models were reconstructed to evaluate resectability parameters including biliary infiltration, vascular involvement, hepatic atrophy and metastasis.

Self-protection against triptolide-induced toxicity in human hepatic cells via Nrf2-ARE-NQO1 pathway.

Objective: To find the signaling pathway of triptolide (TP)-induced liver injury and to reveal whether NF-E2-related factor 2 (Nrf2) plays an important role in cellular self-protection.

Methods: The L-02 and HepG2 cells were cultured and treated with various concentrations of TP. The cell viability was observed, and the cell medium was collected for detecting the aspartate aminotransferase (ALT), alanine aminotransferase (AST), lactate dehydrogenase (LDH), superoxide dismutase (SOD) and L-glutathione production (GSH) levels.

Emodin as an effective agent in targeting cancer stem-like side population cells of gallbladder carcinoma.

Side population (SP) cells are previously identified from bone marrow based on their capacity to efflux of the fluorescent dye Hoechst 33342. Recent studies demonstrate that SP cells isolated from various cancer cell lines and primary tumors possess stem-cell-like properties. Thus, targeting tumor SP cells may provide new strategies for treatment in clinic.

Sclerosing angiomatoid nodular transformation of the spleen: report of five cases and review of literature.

Sclerosing angiomatoid nodular transformation (SANT) of the spleen, a newly defined primary lesion of the spleen, is very rare. Immunohistochemistry is the only way to confirm the diagnosis of SANT. We present the clinical characteristics and postoperative outcomes of five SANT cases that underwent splenectomy from January 2007 to October 2010.

Characterization of cancer stem-like cells derived from a side population of a human gallbladder carcinoma cell line, SGC-996.

The cancer stem cell (CSC) hypothesis proposes that CSCs, which can renew themselves proliferate infinitely, and escape chemotherapy, become the root of recurrence and metastasis. Previous studies have verified that side population (SP) cells, characterized by their ability to efflux lipophilic substrate Hoechst 33342, to share many characteristics of CSCs in multiplying solid tumors. The purpose of this study was to sort SP cells from a human gallbladder carcinoma cell line, SGC-996 and to preliminarily identify the biological characteristics of SP cells from the cell line.
