This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.

The combined application of statins that inhibit HMG-CoA reductase and fibrates that activate PPAR-α can produce a better lipid-lowering effect than the simple application, but with stronger adverse reactions at the same time. In the treatment of hyperlipidemia, the combined administration of TCMs and HMG-CoA reductase inhibitor in treating hyperlipidemia shows stable efficacy and less adverse reactions, and provides a new option for the combined application of drugs. In this article, the pharmacophore technology was used to search chemical components of TCMs, trace their source herbs, and determine the potential common TCMs that could activate PPAR-α. Because there is no hyperlipidemia-related medication reference in modern TCM classics, to ensure the high safety and efficacy of all selected TCMs, we selected TCMs that are proved to be combined with statins in the World Traditional/Natural Medicine Patent Database, analyzed corresponding drugs in pharmacophore results based on that, and finally obtained common TCMs that can be applied in PPAR-α and combined with statins. Specifically, the pharmacophore model was based on eight receptor-ligand complexes of PPAR-α. The Receptor-Ligand Pharmacophore Generation module in the DS program was used to build the model, optimize with the Screen Library module, and get the best sub-pharmacophore, which consisted of two hydrogen bond acceptor, three hydrophobic groups and 19 excluded volumes, with the identification effectiveness index value N of 2. 82 and the comprehensive evaluation index CAI value of 1. 84. The model was used to screen the TCMD database, hit 5,235 kinds of chemical components and 1 193 natural animals and plants, and finally determine 62 TCMs. Through patent retrieval, we found 38 TCMs; After comparing with the virtual screening results, we finally got seven TCMs.

OBJECTIVETo establish LC-MS method in the determination of oxymatrine and its metabolite in plasma and investigate their pharmacokinetics in beagle dogs.

METHODLichrospher C18 column (4.6 mm x 250 mm, 5 microm) was used as the analytical column maintained at 25 degrees C. The mobile phase consisted of 10 mmol x L(-1) CH3COONH4 and CH3OH (25:75). Flow rate was 1 mL x min(-1). Electrospray ionization (ESI) was carried out. The ESI ion source was set in positive ion polasity mode. The selective ion monitoring (SIM) was set at m/z 265.1 and 249.2.

RESULTThe linearity ranged from 2 to 5000 ng x mL(-1) (r = 0.9991). The detection of oxymatrine and its metabolite were 0.6 and 0.3 ng x mL(-1). The RSD(%) within day and between day was less than 4.7%. The recovery of this method was more than 96.5%. The disposition was conformed to a two-compartment model. The T(1/2), Tmax, Cmax, MRT, AUC(0-->24 h) of oxymatrine were (5.5+/-1.58) h, (1.0+/-0.30) h, (2418.3 +/-970.78) ng x mL(-1), (3.2+/-0.64) h, (5797.4+/-908.16) ng x mL(-1) x h accordingly. The corresponding T(1/2), Tmax, Cmax, MRT, AUC(0-->24 h) of matrine were (9.8+/-2.77) h, (1.9+/-1.09) h, (1532.4+/-494.86) ng x mL(-1), (4.4+/-1.97) h, (5530.5+/-1042.65) ng x mL(-1) x h.

CONCLUSIONThis assay was highly sensitive, rapid, simple and specific enough for determining concentrations of oxymatrine and its metabolite matrine in plasma of beagle dog.

This study was aimed to investigate the expression of vascular endothelial growth factor (VEGF) in patients with aplastic anemia. The gene expressions of VEGF in mononuclear cells of bone marrow from 7 cases of aplastic anemia and 12 normal controls were detected by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR). The expressions of VEGF in bone marrow from 20 cases of aplastic anemia and 20 normal controls were also determined by immunohistochemistry assay. The results showed that expression of VEGF mRNA was found in 2 out of 7 (28.57%) bone marrow of patients and in 10 out of 12 (83.33%) bone marrow of normal controls. The VEGF mRNA in patients with aplastic anemia was significantly lower than that in normal controls (P < 0.05). No patients with aplastic anemia showed immunohistochemical staining of VEGF in bone marrow, while 5 out of 20 (25%) normal controls exhibited VEGF positive cells. Bone marrow of aplastic anemia patients contained less VEGF than that of normal persons (P < 0.05). In conclusion, when compared with normal controls, VEGF expression decreased significantly in patients with aplastic anemia at gene transcription level and protein translation level, it may be related to the defect of angiogenesis and thus hematopoiesis in bone marrow of patients with aplastic anemia.

OBJECTIVETo explore the effects and mechanisms of ascorbic acid (AA) and sodium selenite (SS) on growth inhibition and redifferentiation in human gastric cancer cells.

METHODSIn the present study, trypan blue dye exclusion method was used to determine the cell growth curve and mitotic index, cell electrophoresis and colonogenic potential were used as the indexes of redifferentiation. In order to find out the mechanisms of redifferentiation, the activities of superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase (CAT) were assayed, the content of malondialdehyde (MDA), reduced glutathione (GSH) and H2O2 were evaluated.

RESULTSAfter treatment with AA 3 mol/L + SS 2 mu mol/L, the growth rate and mitotic index of human gastric cancer cells (MGc-803) decreased remarkably. The indexes related with cell malignancy were alleviated. For example, cell surface charge was obviously decreased, the electrophoresis rate was dropped from 2.21 to 1.15 mu m.s-1.V-1.cm-1. The indexes related with cell redifferentiation were promoted. For example, the colonogenic potential was decreased to 93.5%. These results indicated that redifferentiation of human gastric cancer cells was successfully induced by AA + SS. The activities of SOD and GPX were significantly higher, while the activity of CAT was slower in treated group than that in the control. The content of MDA was slightly decreased, GSH was sharply decreased, and H2O2 content was dramatically increased.

CONCLUSIONThese results indicated that combination of ascorbic acid and sodium selenite may induce the redifferentiation of human gastric cancer cells and inhibit cell growth by virtue of enhancing the activities of antioxidative enzymes and inducing the formation of H2O2, and altering the cell redox status. Combination of ascorbic acid and sodium selenite may be a potent anticancer agent for human gastric cancer.
