OBJECTIVES Both dental erosion and respiratory symptoms are extra-oesophageal manifestations of gastro-oesophageal reflux disease (GERD). The aim of this study was to determine whether dental erosion was correlated with respiratory symptoms in GERD patients. METHODS 88 GERD patients were recruited and assigned to three groups mainly according to the(More)
Cerium (Ce), one of the lanthanides (Ln), displays a variety of biochemical and physiological effects. However, the potential effect and mechanism of Ce on bone metabolism are not well understood. In this study, we investigated the putative role of Ce in regulating the migration and osteogenic differentiation of bone marrow stromal cells (BMSCs) and the(More)
BACKGROUND Data on the role of dental plaque in the transmission of Helicobacter pylori have varied. Furthermore, there has been few reports on the relationship between dental plaque control and H. pylori infection of gastric mucosa. The purpose of this study was to elucidate this potential relationship. METHODS The (13)C urea breath test was conducted on(More)
Tumstatin is the 28 kDa NC1 domain of the α3 chain of type IV collagen that inhibits pathological angiogenesis and suppresses endothelial cell proliferation and tumor growth. In the present paper, we expressed and purified recombinant human tumstatin protein and then prepared the anti-tumstatin polyclonal antibody. To investigate the expression of tumstatin(More)
OBJECTIVE To investigate the reinfection rate of Helicobacter pylori (H. pylori) in gastric mucosa by two measures of oral plaque control on patients, and to demonstrate the necessity and better method of plaque control on those patients. METHODS 148 patients suffered gastritis or gastroduodenal ulcer were assigned into test group 1 (54 patients), test(More)
Spermidine/spermine N1-acetyltransferase (SSAT) is a key enzyme of polyamine catabolism. In a previous study, we constructed a recombinant adenovirus, Ad-SSAT, which can express human SSAT. In the present study, we investigated the effect of Ad-SSAT on the growth and cell cycle of colorectal cancer cells. We found that Ad-SSAT increased the expression of(More)
PURPOSE The purpose of this study is to construct the expressing plasmid vector containing the GBR gene of Streptococcus mutans and study the immunogenicity of recombinant GBR protein. METHODS The GBR gene was cloned into the expression vector pTriEx-4 through gene cloning techniques by PCR,T-A clone and etc,the recombinant plasmid pTriEx-4-GBR was(More)
OBJECTIVE To compare the expression of CCL28 in minor and major salivary glands and clarify the role it plays in IgA secreting by minor salivary glands in oral cavity. METHODS Labial gland and parotid samples were analyzed with real-time fluorescent quantitative PCR assay for CCL28 mRNA. Rank-sum test was used for data analysis using SPSS 10.0 software(More)
OBJECTIVE To establish a three-dimension finite element model of mandible with two kinds of dental implant and to study the stress of implant-bone interface. METHODS Measuring the data of the components of the dental implant and using spiral CT image reconstruction technique to scan the cross section of the mandible. Three-dimension finite element(More)
OBJECTIVE To observe the antibody responses induced by recombinant plasmid plRES-fimA:IL15 via nasal immunization to BABL/c mice and the regulation of IL-15 to sIgA. METHODS BABL/c mice were immunized with recombinant plasmids pIRES-fimA:IL15 and pIRES-fimA via nasal or intramuscular route. Serum IgG and salivary sIgA levels after immunization were(More)
