AIM To report the long-term effect of stent placement in 115 patients with Budd-Chiari syndrome (BCS). METHODS One hundred and fifteen patients with BCS were treated by percutaneous stent placement. One hundred and two patients had IVC stent placement, 30 patients had HV stent placement, 17 of them underwent both IVC stent and HV stent. All the procedures(More)
Protein fractions were extracted by successive extraction and analysis method in four buckwheat varieties including Japanese spring buckwheat, Japanese summer buckwheat, Yuqiao No. 1 and Yuqiao 6-21. The amino acid and the mineral content of each protein fraction were also analyzed in this paper. The basis for the data on the experiment was the relationship(More)
OBJECTIVE To investigate the effect of body mass index (BMI) and waist hip ratio (WHR) on lumbar lordosis and sacrum slant angle in the patients with low back pain, and to discuss the theory of low back pain induced by obesity. METHODS The Roland Disability Questionnaire (RDQ) was answered by 98 middle and elderly women with low back pain, whose body(More)
PURPOSE To describe and propose a sonographic classification of the blood-draining pathways of obstructed hepatic veins in Budd-Chiari syndrome. METHODS This retrospective study included 206 patients with hepatic vein obstructions who underwent sonographic examination. We evaluated the afflicted hepatic veins, as well as the course, orifice, blood flow(More)
This study focuses on the preparation of a new type of Prussian Blue/polyaniline (PB/PANI)-modified electrode as oxygen reduction cathode, and its availability in microbial fuel cell (MFC) for biological power generation. The PB/PANI-modified electrode was prepared by electrochemical and chemical methods, both of which exhibited good electrocatalytical(More)
OBJECTIVE To explore the feasibility of transplantation of frozen autogenous mandible with delayed implantation. METHODS Operations were performed to create two defects in the bilateral mandible of 16 dogs. The left defect was grafted by composite transplantation of frozen autogenous mandible (immersed in -196 degrees C liquid nitrogen) with fresh(More)
To date, commercial 4D-CT systems typically depend on an external respiratory monitoring device. Immobilizing patients in a thermoplastic mask while receiving radiotherapy may result in a failure of 4D-CT reconstruction. The aim of this study is to investigate the feasibility of 4D-CT reconstruction based on a method using pulmonary average CT values (ACV)(More)
Insulin-like growth factor-I (IGF-I) and its receptor (IGF-IR) have tremendous trophic effects on the central, peripheral and enteric neurons. The loss of IGF-IR contributes to the development of diabetic gastroparesis. However, the nature and the function of the IGF-IR(+) cells in the gastric myenteric plexus remain unclear. In this study, anti-ChAT,(More)
HCN2 channels are involved in the spontaneous rhythmic activities of some CNS neurons and act by generating I(f) current. The gastrointestinal (GI) tract is known to be capable of spontaneous rhythmic activity; however, the possible role of HCN2 channels in this organ has not yet been elucidated. This study investigated the distribution of HCN2-positive(More)
