OBJECTIVE Sinistral, or left-sided, portal hypertension (SPH) is a rare cause of upper gastrointestinal hemorrhage. This retrospective analysis summarizes the clinical features of SPH and the results of surgical treatment. SUBJECTS AND METHODS Between 2000 and 2009, patients from our hospital diagnosed with SPH were identified. Diagnosis of SPH was based(More)
AIM To investigate the lymph node metastasis patterns of gallbladder cancer (GBC) and evaluate the optimal categorization of nodal status as a critical prognostic factor. METHODS From May 1995 to December 2010, a total of 78 consecutive patients with GBC underwent a radical resection at Liaocheng People's Hospital. A radical resection was defined as(More)
To investigate the predictive value of combined use of D-dimer and P-selectin for splenic or portal vein thrombosis (SPVT) after splenectomy. A prospective study was carried out in 82 patients who had undergone splenectomy for portal hypertension secondary to hepatic cirrhosis. Plasma levels D-dimer and P-selectin were measured before and after the(More)
The electrooxidation of ethylene glycol (EG) and glycerol (G) has been studied: in alkaline media, in passive as well as active direct ethylene glycol fuel cells (DEGFCs), and in direct glycerol fuel cells (DGFCs) containing Pd-(Ni-Zn)/C as an anode electrocatalyst, that is, Pd nanoparticles supported on a Ni-Zn phase. For comparison, an anode(More)
Improved performance through milling: A method for enhancing the catalytic activity of supported metal nanoparticles is reported. This method enhances the activity for the ethanol electro-oxidation of a supported palladium catalyst. The much higher catalytic performance is ascribed to the increased electrochemically active surface area as well as the(More)
Fe nanocrystal catalysts were synthesized by electrochemistry. Shape transformations of Fe nanocrystals from rhombic dodecahedra and tetragonal bipyramids, both bounded by {110} facets, to 18-facet polyhedra enclosed by different combinations of {110} and {100} facets and finally to cubes exclusively covered by {100} facets have been achieved. A study of(More)
CoPt nanoparticles supported on a glassy carbon electrode (denoted as CoPt/GC) were prepared by galvanic replacement reaction between electrodeposited Co nanoparticles and K(2)PtCl(6) solution. Scanning electron microscope (SEM) and transmission electron microscope (TEM) were both employed to characterize the CoPt nanoparticles. It was shown that the CoPt(More)
