OBJECTIVETo observe the intervention and mechanism of Qushi Huayu Recipe (QHR) on gene expression profiles in high lipid diet induced fatty liver rats.
METHODSFatty liver model was prepared in 20 male SD rats using single high fat diet (88% common forage +2% cholesterol +10% lard). Four weeks after modeling they were divided into the model group and the QHR group according to random digit table, 10 in each group. QHR (at 0. 93 g crude drug/100 g body weight) and distilled water was respectively to rats in the QHR group and the model group by gastrogavage while modeling, once per day. Meanwhile, 10 SD male rats were recruited in a normal group, administered with equal volume of distilled water by gastrogavage. At the end of week 8 all rats were sacrificed, and blood and livers were collected for subsequent analysis. Contents of liver triglyceride (TG) and free fatty acid (FFA) , activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected using biochemical assay. Pathological changes of liver tissue were observed using H&E and oil red O stain. Liver gene expressions were detected by Affymetrix gene expression profiles. Differentially expressed genes were compared between the QHR group and the model group, functions of differentially expressed genes and signal pathways involved analyzed. Ten differentially expressed genes involved in glycolipid metabolism with fold change more than 2 were selected for verification by real-time PCR.
RESULTS(1) Compared with the normal group, contents of liver TG and FFA, and serum activities of ALT and AST obviously increased in the model group (P <0. 01). Compared with the model group, contents of liver TG and FFA, and activities of ALT and AST obviously decreased in the QHR group (P <0. 05, P <0. 01). QHR could reduce high fat induced fatty degeneration of liver cells , alleviate inflammation, and improve pathological changes of liver tissue. (2) Compared with the model group, there were 80 differentially expressed genes (with fold change > 2, P < 0.05) with clear functions and appointed gene names, including 44 up-regulated and 36 down-regulated genes. Eighty genes were involved in 27 signal pathways with statistical difference, including glycerolipid metabolism, adipocytokine signaling pathway, insulin signal pathway, drug metabolism signal pathway, etc (P < 0.05). (3) RT-PCR results of 10 glycolipids metabolism regulating genes such as Gk, Scd1, Gpat2, G6pc, Irs1, and so on showed that all RT-PCR genes were completely coincide with up-regulated or down-regulated tendency in results of gene chips. 80% genes had approximate fold change.
CONCLUSIONQHR could regulate gene expressions related to fat metabolism, carbohydrate metabolism, anti-lipid peroxidation, and drug metabolism in high fat diet induced fatty liver rats, and its comprehensive pharmacological actions could be manifested.

OBJECTIVETo observe the biological changes of primary human nasopharyngeal epithelial cells in the early stage of immortalization.
METHODSThe morphological changes of nasopharyngeal epithelial cells were observed by phase contrast microscopy, and the activity profile of senescence-associated beta-galactosidase (SA-beta-Gal) was detected by SA-beta-Gal staining. The expression of p16(INK4a) protein was tested by immunochemical assay, and the life span in vitro of nasopharyngeal epithelial cells was calculated as population doublings. In addition, the expression of Epstein-Barr (EB) virus latent membrane protein 1 (LMP1) was also detected by immunofluorescence staining.
RESULTSMorphologically, cells treated with EB virus and 12-o-tetradecanoyl-phorbol-13-acetate (TPA) formed multi-layer foci, and their cellular life span in vitro was extended (about 155 days of culture). A low percentage of cells (about 4.8%) expressed SA-beta-Gal activity at late primary culture, and did not always express p16(INK4a) protein in the progression of culture.
CONCLUSIONSNasopharyngeal epithelial cells treated with EB virus in cooperation with TPA can pass through the stage of senescence and enter the early stage of immortalization. Some changes of phenotype occur in these cells. Our results provide data for further studying the mechanism of immortalization and the establishment of a human nasopharyngeal epithelial cell line.

Ranolazine and metabolites in dog urine were identified by LC-MS(n). Dog urine samples were collected after ig 30 mg x kg(-1) ranolazine, then the samples were enriched and purified through solid-phase extraction cartridge. The purified samples were analyzed by LC-MS(n). The possible metabolites were discovered by comparing the full scan and SIM chromatograms of the test samples with the corresponding blanks. Seventeen phase I metabolites and fourteen phase II metabolites were identified in dog urine. Three metabolites were identified by comparing with the control article. The metabolites were formed via the following metabolic pathways: O-demethylation, O-dearylation, hydroxylation, N-dealkylation, amide hydrolysis, glucuronidation and sulfation. The LC-MS(n) method is suitable for the rapid identification of drug and its metabolites in biologic samples.
