METHODS: A total of 100000 patients, diagnosed with either type 2 DM or HTN, were randomly selected from the 2004 Korean National Health Insurance System claims. Among them, 360 diabetes and 351 hypertensive patients with gastric cancer who had been regularly treated without chemotherapy from January 2005 to December 2010 were selected. They were divided into three groups according to their treatment methods: total gastrectomy(TG), subtotal gastrectomy(STG) and endoscopic resection(ER). RESULTS: The drug discontinuation rate of antidiabetic and anti-hypertensive agents after gastric cancer treatment was 9.7% and 11.1% respectively. DM appeared to be improved more frequently(22.8%) and earlier(mean ± SE 28.6 ± 1.8 mo) in TG group than in the two other groups [improved in 9.5% of ER group(37.4 ± 1.1 mo) and 6.4% of STG group(47.0 ± 0.8 mo)]. The proportion of patients treated with multiple drugs decreased more notably in TG group compared to others(P = 0.001 in DM, and P = 0.035 in HTN). In TG group, adjusted hazard ratio for theimprovement of DM was 2.87(95%CI: 1.15-7.17) in a multi-variate analysis and better control of DM was observed with survival analysis(P < 0.001).CONCLUSION: TG was found to decrease the need for anti-diabetic medications which can be reflective of improved glycemic control, to a greater extent than either ER or STG in non-obese diabetic patients.展开更多

Methods： In mice, blood biochemistry and histopathology were assessed in carbon tetrachloride（CCl4）-induced oxidative hepatic injury in vivo. The animal groups included vehicle-treated control, CCl4, SKT 500 mg/（kg·day） CCl4＋SKT 200 or 500 mg/（kg·day）. In Hep G2 cell, tert-butyl hydroperoxide（t BHP） induced severe oxidative stress and mitochondrial dysfunction in vitro. The cyto-protective effects of SKT were determined by 3-（4,5-dimethylthiazol）-2,5-diphenyltetrazolium bromide（MTT） assay, fluorescence activated cell sorting analysis and western blotting. Results： The administration of SKT prevented liver damage induced by CCl4 in mice, by inhibition of hepatocyte degeneration and inflammatory cell infiltration as well as plasma parameters such as alanine aminotransferase（P〈0.01）. Moreover, treatment with t BHP induced hepatocyte death and cellular reactive oxygen species production in hepatocyte cell line. However, SKT pretreatment（30–300 μg/m L） reduced this cell death and oxidative stress（P〈0.01）. More importantly, SKT inhibited the ability of t BHP to induce changes in mitochondrial membrane transition in cell stained with rhodamine 123（P〈0.01）. Furthermore, treatment with SKT induced extracellular signal-regulated kinases-mediated nuclear factor erythroid-2-related factor 2（Nrf2） activation as well as the expressions of heme oxygenase 1 and glutamate-cystein ligase catalytic, Nrf2 target genes. Conclusion： SKT has the ability to protect hepatocyte against oxidative stress and mitochondrial damage mediated by Nrf2 activation.展开更多
