Targeted delivery of contrast agents is a highly desirable strategy for enhancing diagnostic efficiency and reducing side effects and toxicity. Water-soluble and tumor-targeting superparamagnetic iron oxide nanoparticles (SPIONs) were synthesized by loading hydrophobic SPIONs into micelles assembled from an amphiphilic block copolymer poly(ethylene glycol)-(More)
BACKGROUND & OBJECTIVE Focal nodular hyperplasia (FNH) is a rare benign hepatic tumor and its imaging diagnosis remains difficult. This study was to analyze dynamic contrast-enhanced MR imaging and digital subtraction angiography (DSA) manifestation of FNH, and to improve the diagnostic accuracy of FNH. METHODS The MRI and DSA imaging data of 30 patients(More)
PURPOSE Pancreatic carcinoma is one of the most malignant tumors of the alimentary system, with relatively high incidence rates. The purpose of this study was to assess the efficacy and safety of two regimens for advanced pancreatic carcinoma: continuous transarterial infusion versus systemic venous chemotherapy with gemcitabine and 5-fluorouracil.

BACKGROUND & OBJECTIVE Advanced pancreatic cancer is mainly treated by chemotherapy with poor prognosis. This study was designed to evaluate clinical efficacy and application of selective continuous transarterial infusion chemotherapy in treating patients with advanced pancreatic cancer. METHODS Twenty patients with advanced pancreatic cancer were treated(More)
OBJECTIVE To evaluate the cytotoxicity of poly(ethylene glycol)-block-poly(D,L-lactic acid) (PEG-PDLLA) nanovesicles loaded with doxorubicin (DOX) and the photosensitizer hematoporphyrin monomethyl ether (HMME) on human hepatocellular carcinoma HepG2 cells and to investigate potential apoptotic mechanisms. METHODS PEG-PDLLA nanovesicles were(More)
