OBJECTIVE To investigate the effect of Tanshinone II A on K562 cell-line and its possible mechanism. METHODS Cell culture, cytomorphology and cytometrics were used. RESULTS The proliferative inhibition of K562 cells induced by Tanshinone II A was dose-independent, and the degrees of erythroid differentiation induced by 30 nmol/L ACM and 0.5 microgram/ml(More)
OBJECTIVE With an increased use of endoscopic retrograde cholangiopancreatography (ERCP), post-ERCP complications have attracted much attention. We aimed to identify independent risk factors of post-ERCP pancreatitis (PEP) and hyperamylasemia, and to develop a simple scoring system of the factors contributing to the clinical prevention against PEP.

OBJECTIVE To observe the effect of autologous dendritic cells (DC) on positive Philadelphia (Ph+) chromosome cells of Chronic Myeloid Leukemia (CML) in vitro. METHODS DCs and T cells extracted from the peripheral blood mononuclear cell (PBMNC) of 4 CML patients with Ph+ chromosome in chronic phases were amplified in a special liquid culture system. The(More)
OBJECTIVE Pancreatic duct guidewire placement (PDGP) includes double guidewire technique (DGT) and transpancreatic sphincterotomy (TPS). DGT can be switched to TPS with ease due to the existing guidewire in the pancreatic duct. In this study, we aimed to combine DGT and TPS as a single technique, named sequential PDGP, and to compare its performance with(More)
OBJECTIVE In order to search for more effective treatment regimen of chronic myeloid leukemia (CML). METHODS Semisolid culture and conventional chromosome assay were used to evaluate the effect of interferon (IFN) and Ara-c on K562 cell line and BMMNCs from CML patients and normal controls. RESULTS IFN had no obvious inhibitory effect on K562 cell. IFN(More)
