In this study, we first sought to determine the existence of side population (SP) cells in pancreatic cancer cell lines. Furthermore, we compared the biological characteristics of SP and non-SP cells. The presence of side population cells in pancreatic cancer cell lines was detected by Hoechst 33342 staining and FACS analysis. Cell cycle distribution was(More)

From 1957 to 1985, 842 patients were diagnosed as having thoracic hydatid cysts; 810 cysts were intrathoracic, 29 occurred on the "liver roof," 2 were cardiac, and 1 was on the chest wall. A total of 1,010 surgical procedures were performed in 807 patients (35 refused operation). There was a total operative mortality of 0.6% (5 deaths). Procedures became(More)
Digestive malignancies, especially pancreatic cancer (PC), gastric cancer (GC), and colorectal cancer (CRC), still occur at persistently high rates, and disease progression in these cancers has been associated with tumor immunosurveillance escape. Natural killer (NK) cell dysfunction may be responsible for this phenomenon, however, the exact relationship(More)
Increasing evidence indicates an important role of transcription factor Yin Yang-1 (YY1) in human tumorigenesis. However, its function in cancer remains controversial and the relevance of YY1 to pancreatic ductal adenocarcinoma (PDAC) remains to be clarified. In this study, we detected YY1 expression in clinical PDAC tissue samples and cell lines using(More)
OBJECTIVES To establish a gemcitabine-resistant pancreatic cancer cell line SW1990/GZ, and to explore the relationship between drug-resistant cell line SW1990/GZ and pancreatic cancer stem cell. METHODS Gemcitabine-resistant pancreatic cancer cell line SW1990/GZ was obtained by treating parental cell line SW1990 in vitro with increasing dosage of(More)
OBJECTIVE To evaluate the methods of diagnosis and surgical treatment for nonfunctional islet cell tumor (NICT). METHODS Forty-four patients with non-functional islet cell tumor treated at the First Affiliated Hospital of Nanjing Medical University during January 1968 to June 2008 were analyzed retrospectively. There were 9 males and 35 females, aged from(More)
