Clinical epidemiological survey of gallbladder carcinoma in northwestern China, 2009-2013: 2379 cases in 17 centers.

Objective: To analyze the clinical epidemiological characteristics of patients with gallbladder carcinoma recruited from 17 hospitals in five northwestern provinces of China (Shaanxi Province, Gansu Province, Qinghai Province, Ningxia Hui Autonomous Region, and Xinjiang Uygur Autonomous Region) from 2009 to 2013, and to summarize the clinical diagnosis and treatment data of gallbladder carcinoma.

Methods: Clinical information of 2379 patients with gallbladder carcinoma from 17 hospitals in five northwestern provinces of China was retrospectively collected and analyzed using the "Questionnaire for Gallbladder Carcinoma Patients in Northwestern Area of China." All information was verified with EpiData software and analyzed with SPSS 13.

Characterization of a stem-like population in hepatocellular carcinoma MHCC97 cells.

A small stem-like subpopulation was isolated from human hepatocellular carcinoma (HCC) MHCC97 cells, characterized by their high efflux ability of the Hoechst 33342 dye. These side population (SP) cells were able to generate a heterogeneous mixture of SP and main population (MP) cells, while the MP cells rarely generated SP cells. Cell cycle analysis also revealed that more SP cells were in the G0 phase.

[Effects and mechanism of decorin on the proliferation of HuH7 hepatoma carcinoma cells in vitro].

Aim: To investigate the effects and mechanism of decorin( DCN) on the proliferation of HuH7 hepatoma carcinoma cell line in vitro.

Methods: Hepatoma carcinoma cells was cultured with DCN in different concentration (0, 25, 50, 75, 100, 125, 150, 200 microg/L) for different time(12, 24, 48, 72 h and 2 weeks). Cell activities were studied by MTT and clone test.
