AIM To investigate the effect of angiopoietin-1 (Ang-1) on biological behaviors in vitro and tumorigenesis and angiogenesis in vitro of human gastric cancer cells. METHODS Human full-length Ang-1 gene was cloned from human placental tissues by RT-PCR method. Recombinant human Ang-1 antisense eukaryotic expression vector was constructed by directional(More)
The N-myc downstream-regulated gene-1 (NDRG1) has recently been proposed as a metastasis suppressor, but its precise role remains unclear. To investigate whether NDRG1 can indeed influence the metastasis progress, expression of endogenous NDRG1 was knocked down in human AGS gastric adenocarcinoma cells using RNA interference. Stable NDRG1 “silenced”(More)
BACKGROUND AND AIMS HER2, an oncogene, has been found to be over-expressed in 10-40% of human gastric carcinomas. The aims of this study were to investigate if a fusion protein consisting of anti-HER2 sFv and constitutively active caspase-3 was capable of inducing apoptosis in HER2-expressing human gastric cancer cells and blocking the growth of human(More)
OBJECTIVE To investigate the effect of Earthworm decoction on the airway inflammation of experimental bronchial asthma in guinea pigs and inquire into the mechanism in the decoction. METHOD Forty-eight guinea pigs were randomly divided into six groups: the control group, the model group, the dexamethasone group, the Xiaoqinglong decoction group, the(More)
AIM Rosiglitazone is one of the specific PPARγ agonists showing potential therapeutic effects in asthma. Though PPARγ activation was considered protective in inhibiting airway inflammation and remodeling in asthma, the specific mechanisms are still unclear. This study was aimed to investigate whether heme oxygenase-1 (HO-1) related pathways were involved in(More)
OBJECTIVE To investigate the association of -141C insert/delete polymorphism with schizophrenia in Wuhan of Hubei province. METHODS A case-control study was conducted to analyze the polymorphism in the D(2) receptor gene promoter region with schizophrenia. A total of 120 cases of schizophrenia diagnosed according to CCMD-II R criteria and 100 normal(More)
In the field of plastic Compression processing and manufacturing technology, A new idea of volumetric liquid plastic molding manufacturing's technology is proposed. The technology is using the transmission of liquid force which is advantage of the fine mechanical properties, and synthetic rubber has a good property against oil, pressure, flexible features,(More)
OBJECTIVE To investigate the role of human angiopoietin-1 (Ang1) in tumorigenesis and angiogenesis of human gastric cancer cell line SGC7901 in nude mice. METHODS Recombinant human Ang1 sense or antisense eukaryotic expression vectors were constructed, and transfected by lipofectin into human gastric cancer line SGC7901. Stable transfectants were obtained(More)
AIM To explore the influence of angiostatin up-regulation on the biologic behavior of gastric cancer cells in vitro and in vivo, and the potential of angiostatin gene therapy in the treatment of human gastric cancer. METHODS Mouse angiostatin cDNA was subcloned into the eukaryotic expression vector pcDNA3.1(+) and identified by restriction endonucleases(More)
OBJECTIVE To explore the effects and the mechanism of Wuwei Dilong Decoction (Schisandra Fruit and Earthworm Decoction) for treatment of asthma. METHODS The asthma guinea pig model was established with spray of ovalbumin (OVA). Fifteen days later, the guinea pigs were administered by intra-gastric perfusion of Wuwei Dilong Decoction once a day for 8(More)
