PURPOSE The aim of this study was to investigate the signaling mechanisms surrounding changes in tight junction (TJ) and the permeability of human intestinal epithelial cell induced by tumor necrosis factor-alpha (TNF-α). METHODS To confirm that TNF-α induces epithelial barrier hyperpermeability by disrupting tight junction, Caco-2 cells were exposed to(More)
OBJECTIVE To study the influence of lipopolysaccharide (LPS) on the permeability of rat brain microvascular endothelial cells (BMECs) and possible molecular mechanism. METHODS Monolayers of primary rat BMECs were separated and cultured, and then treated with (LPS group) or without LPS (control group). The barrier integrity was measured by transendothelial(More)
OBJECTIVE To observe and compare the effects of aging and hypertension on rats' aortic vascular smooth muscle cells (VSMCs) and the effects of the extracts from Panax ginseng, Panax notoginseng and Ligusticum chuanxiong. METHODS The rat aortic VSMCs model was established using the method of primary cell culture. Of them, the rats of the aging experiment(More)
The semileptonic decays of meson Bc to a P-wave charmonium state χc( PJ) or hc( P1) are computed. The results show that the decays are sizable so they are accessible in Tevatron and in LHC, especially, with the detectors LHCB and BTeV in the foreseeable future, and of them, the one to the P1 charmonium state potentially offers us a novel window to see the(More)
The decay constants of pseudoscalar heavy mesons of 0− state are computed by means of the relativistic (instantaneous) Salpeter equation. We solved the full Salpeter equation without making any further approximation, such as ignoring the small component wave function. Therefore, our results for the decay constants include the complete relativistic(More)
OBJECTIVE To evaluate the value of reflux diagnostic questionnaire in the diagnosis of children with gastroesophageal reflux disease (GERD). METHODS Forty-five children aged 7-16 years old referred for suspected GERD with vomiting/regurgitation, nausea, heartburn/retrosternal pain, abdominal pain, epigastric pain, acid regurgitation and pain while(More)
BACKGROUND Psoriasis is a common inflammatory skin disease, yet knowledge of the factors that may induce, trigger, or exacerbate psoriasis is not fully delineated. Recent advances have improved our understanding of the link between psoriasis and cell-wall-deficient bacteria (CWDB) infections. In the present study we assessed the prevalence of CWDB infection(More)
OBJECTIVE To study the chemical constituents from the supercritical CO2 extraction of Schisandra chinensis. METHODS The compounds were separated and purified by conventional column chromatography and their structures were identified by spectroscopic methods. RESULTS Nine compounds were isolated from the supercritical CO2 extraction of Schisandra(More)
