OBJECTIVE To explore the influence of compound whole grain complex antioxidant chain on oxidative stress to the hyperlipidemia population. METHODS From March 2008 to March 2009, 418 hyperlipemia residents (45 to 75 years of age) of Han group were screened from 3 main districts in Nanjing, according to the community, blood lipids and oxidative indicators,(More)
Phytochemical investigation on the stems of Kadsura renchangiana led to the isolation of two new sesquiterpenoids, renchangianins F and G (1 and 2). Their structures were elucidated by spectroscopic methods, including 2D NMR techniques. The in vitro cytotoxic activities of the isolates were studied against HepG2, A549, and LN229 cancer cell lines.
Previous gastrectomy has been considered a relative contraindication to laparoscopic cholecystectomy (LC). The aim of this study was to evaluate the safety and efficacy of LC in patients with a history of gastrectomy. From a database of 1 104 consecutive patients with symptomatic gallstone disease, who underwent LC between April 1992 and January 2007, 51(More)
Two new long-chain unsaturated compounds, (2E, 6E)-10-methoxy-3,7-dimethyl-10-oxodeca-2,6-dienoic acid (1) and (2E, 6E)-3,7,11-trimethyldodeca-2,6-dienedioic acid (2), together with seven known compounds were isolated from a marine-derived Streptomyces sp. Their structures were determined by spectroscopic methods, including 2D NMR techniques. Compounds 1(More)
The aerial parts of Epilobium plants are widely used as folk medicine and food around the world. The present study was aimed to investigate the antioxidant activities and active chemical constituents from Epilobium angustifolium L. The results revealed that the EtOAc extract, rich in phenolic compounds and flavonoids (16.81 ± 0.67 g GAE/100 g extract and(More)
One new compound, himalain A (1), together with 12 known compounds were isolated from Mirabilis himalaica. Their structures were determined by spectroscopic methods, including 2D NMR techniques, and the absolute configuration of the 1,2-diol moiety in 1 was defined through Riguera's method. All isolated compounds were tested for their cytotoxic and(More)
