BACKGROUND Cardiovascular disease (CVD) and colon cancer incidence are known to be closely related to dietary factors. This article evaluated effects of krill oil (KO) on serum lipids of hyperlipidemia rats and human colon cancer cells (SW480). Serum lipids of rats fed with high fat diet (HFD) and different doses of KO were measured by automatic analyzer.(More)
Glucuronidation and sulfation represent two major pathways in phase II drug metabolism in humans and other mammalian species. The great majority of drugs, for example, polyphenols, flavonoids and anthraquinones, could be transformed into sulfated and glucuronidated conjugates simultaneously and extensively in vivo. The pharmacological activities of drug(More)
OBJECTIVE To investigate the dynamic trends of activities of matrix metalloproteinase (MMP)-2/9 and protein expressions of their inhibitors-tissue inhibitor of matrix metalloproteinase (TIMP)-1/2 during the progression of pulmonary fibrosis in rats so as to get insight of the roles played by MMP-2/9 in lung injury and fibrogenesis. METHODS Forty-eight SD(More)
The in vivo and in vitro metabolism of genipin was systematically investigated in the present study. Urine, plasma, feces, and bile were collected from rats after oral administration of genipin at a dose of 50 mg/kg body weight. A rapid and sensitive method using ultraperformance liquid chromatography coupled with electrospray ionization quadrupole(More)
OBJECTIVE To study the mechanism of Fuzheng Huayu (FZHY) recipe against pulmonary fibrosis relating to MMP-2 activity and type IV collagen expression at lung tissue. METHOD The pulmonary fibrosis model was induced by intratracheal instillation with bleomycin once in rats. The models were divided into 3 groups: model control, FZHY recipe treated, and(More)
Yeputaoteng is the dried ground part of Ampelopsis sinica (Miq.) W.T. Wang, which is widely used in traditional Chinese medicine for preventing and treating tumors, chronic nephritis, hepatitis, rubella, traumatic bleeding, stomach heat and vomiting. A simple and reliable method using high-performance liquid chromatography with diode array detection(More)
OBJECTIVE To research on the preparation of Arctigenin in vitro. METHODS Took enzyme concentration, time course and substrate concentration as investigation factors, used Box-Behnken design-response surface methodology to optimize the enzyme hydrolysis path of Arctigenin. RESULTS The best operational path for Arctigenin was as follows: the temperature(More)
BACKGROUND Thoracic lymph node (LN) metastasis is the determining factor for NSCLC staging. However, enlargement in thoracic LNs, which can be detected by chest computed tomography (CT), may not be adequate for NSCLC staging. This study aimed to investigate the effectiveness of a new transbronchial needle aspiration (TBNA) procedure to improve the(More)
The optimum conditions of baicalin hydrolysis into baicalein by immobilized beta-glucosidase in a two-phase system was studied and the yield was observed. A two-phase system comprising of sodium acetate buffer and chloroform was determined by comparing the solubleness of baicalein in different solvents and partition coefficient of baicalein in related(More)
OBJECTIVE To optimize the extraction process and macroporous resin for purification of Timosaponin B II from Anemarrhena asphodeloides. METHODS Orthogonal design L9 (34) was employed to optimize the circumfluence extraction conditions by taking the extraction yield of Timosaponin B II as index. The absorption-desorption characteristics of eight kinds of(More)
