OBJECTIVE This review was an effort to systematically examine the nationwide data available on pediatric burns requiring hospitalization to reveal burn epidemiology and guide future education and prevention. METHODS The China Biomedical Disk Database, Chongqing VIP Database, and China Journal Full-Text Database were searched for articles reporting data on(More)
INTRODUCTION Myeloma bone disease (MBD) is the result of the increased activity of osteoclasts (OCs), which is not accompanied by a comparable increase of osteoblast (OB) function, thus leading to enhanced bone resorption. Osteoblasts can also regulate osteoclast activity through expression of cytokines, such as receptor activator of nuclear factor-κB(More)
STUDY DESIGN A prospective, randomized study of the radiographic outcomes in patients undergoing single-level cervical arthroplasty with Bryan disc and ProDisc-C prosthesis. OBJECTIVE The purpose of this trial was to compare the alignment changes of Bryan disc arthroplasty (modified techniques) with ProDisc-C arthroplasty. SUMMARY OF BACKGROUND DATA(More)
We sought to compare the preventive effects of mitomycin-C(MMC) and chitosan on intraarticular adhesion after knee surgery in rabbits. For this purpose, 48 New-Zealand rabbits were randomly and equally divided into MMC, chitosan, and control groups. Approximately 10 × 10 mm2 of the cortical bone was removed from both sides of left femoral condyle and the(More)
Structural properties of cellulose gels Perloza MT, materials designed for the preparation of chromatographic adsorbents and immobilized biocatalysts, having a different content of polymer were investigated using a batch solute exclusion method. A homologous set of dextrans with a wide range of molecular weights was used to probe the pore accessibility of(More)
OBJECTIVE Patients with hypertensive left-ventricular hypertrophy (LVH) have lower coronary flow reserve (CFR). Whether carvedilol can improve CFR of patients with hypertensive LVH is unknown. We aimed to investigate the effects of carvedilol on CFR in patients with hypertensive LVH. METHODS Sixty-three patients were randomly divided into two groups for(More)
In this paper, after the discussion of user models and ontology-based domain knowledge representation in intelligent tutoring systems, a formal model of intelligent pedagogical agents is presented and the teaching processes of these agents is analyzed. Domain knowledge are represented based on ontologies to improve the sharing and reusing of teaching(More)
Protein sample preparation is a crucial step in a 2-DE proteomics approach. In order to establish a routine protocol for the application of proteomics analysis to aphids, this study focuses on the specific protein extraction problems in insect tissues and evaluates four methods to bypass them. The approaches of phenol extraction methanol/ammonium acetate(More)
A formal model of agent-based knowledge management in intelligent tutoring systems is presented in this paper. It consists of three agents, a knowledge acquisition agent, a knowledge distribution agent and a knowledge maintaining agent. The knowledge acquisition agent is responsible for the construction of user model and domain knowledge base. The knowledge(More)
A user model with emotional analysis in intelligent tutoring systems is presented in this paper. After introducing user characteristics, an emotional analysis module is introduced to discuss expression recognition, expression classification and emotional states confirming in our user model in detail, in order to improve pedagogical effects.
