OBJECTIVE To determine the effects of total parenteral nutrition (TPN) and enteral nutrition (EN) on biochemical and clinical outcomes in pancreatic cancer patients who underwent pancreaticoduodenectomy. METHODS From the year 2006 to 2008, 60 patients who underwent pancreaticoduodenectomy in Tianjin Third Central Hospital were enrolled in this study. They(More)
We investigated the effect of chemical oxygen demand (COD)/N ratio on polyhydroxybutyrate (PHB) accumulating ability in an anaerobic/aerobic cycle sequential batch reactor (SBR). Compared the COD/N ratio of 10, 20, 50, and 125, the COD/N of 125 was the most suitable nutritional proportion. When COD was 1,200 mg/L and COD/N/P was 1,200/9.6/30, activated(More)
Coagulation followed by sedimentation, as a conventional technique in the water treatment plant, can be the first line of defense against exposures of carbon nanotubes (CNTs) to aquatic organisms and human beings, which has been rarely documented. This study investigated the removal of dispersant-stabilized CNT suspensions by poly aluminum chloride (PACl)(More)
Discharged carbon nanotubes (CNTs) can adsorb the widely-distributed humic acid (HA) in aquatic environments and thus be stabilized. HA-stabilized CNTs can find their way into and challenge the potable water treatment system. This study investigated the efficiency of coagulation and sedimentation techniques in the removal of the HA-stabilized multi-walled(More)
OBJECTIVE To estimate the broad-sense heritability of the production of Glycyrrhiza uralensis and the content of glycyrrhizin as well as the genetic relationship of various growth indexes and biomass indexes, and provide the scientific basis for establishment of high quality licorice cultivate technology system. METHOD The randomized method was used to(More)
OBJECTIVE We studied the licorice provenance rule under the manual simulative water stress conditions, discussed geographical variation pattern and the ecology mechanism and laid the theoretical basis for the licorice seed regionalization and the seed allocation. METHOD On the spot we investigated and collected seed materials. Setting up water potential(More)
The main objective of this work was to investigate the influence of different oxygen supply patterns on poly-β-hydroxybutyrate (PHB) yield and bacterial community diversity. The anaerobic-aerobic (A/O) sequencing batch reactors (SBR1) and feast-famine (F/F) SBR2 were used to cultivate activated sludge to produce PHB. The mixed microbial communities were(More)
PTA wastewater discharged from a factory was selected as the research object in this project and CODcr was selected as the characteristic pollution factor. Static adsorption and soil column leaching experiments of silty clay and clayey soil were carried out to study the adsorption, bio-degradation and dispersion coefficient of CODcr in PTA wastewater.(More)
The anaerobic baffled reactor (ABR) was used to treat alkaline-surfactant-polymer (ASP) flooding wastewater in the Daqing oilfield. With the ABR, hydraulic retention time (HRT)was reduced from 72  to 24 h, the bioreactor purification capability gradually improved. After the ABR running for 100 days, the removal rate of raw oil, suspended solid and(More)
