3Effect of Helicobacter pylori infection on gastric epithelial cell proliferation显示文摘INTRODUCTION Helicobacter pylori(H.pylori)infection is one ofthe main pathogens of chronic gastritis and duodenalulcer(DU),and it may be considered as a riskfactor in the incidence of gastric cancer.H.pylori infection may lead to the anomaly of gastricepithelial cell proliferation which is closely relatedto the development of gastric cancer.Vacuolatingcytotoxin(VacA)is an important virulence andvacA subtype determines the toxic activity.According to its signal sequence,it can be groupedinto type sla,slb,slc and s2.Strains harboringvacAsla are more closely related with digestivediseases and may be the strains with high toxicity.The effect of H.pylori infection onGao H Wang JY Shen XZ Liu JJ 2000World Journal of Gastroenterology2000,6,3:14

6Mechanism of frost heave by film water migration under temperature gradient显示文摘IT is well known that there exists unfrozen film water in frozen soils due to the action of sur-face energy among soil particles and frost heave occurs by water migration under the tempera-ture gradient. The problem is how to determine the amount of frost heave quantitatively. The amount of frost heave induced by ice segregation can be calculated by the following e-quations:Xu, XZ Wang, JC Zhang, LX Deng, YS Chuvilin, EM Yershov, ED Ishizaki, T Fukuda, M 1997Chinese Science Bulletin1997,42,15:6

9Sequence variations of the S7 ribosomal protein gene in primitive cyprinid fishes: Implication on phylogenetic analysis显示文摘Cyprinidae is the largest fish family in the world and contains about 210 genera and 2010 species. Appropriate DNA markers must be selected for the phylogenetic analyses of Cyprinidae. In present study, the 1st intron of the S7 ribosomal protein (r-protein) gene is first used to examine the relationships among cyprinid fishes. The length of the 1st intron obtained by PCR amplification ranges from 655 to 859 bp in the 16 cyprinid species investigated, and is 602 bp in Myxocyprinus asiaticus. Out of the alignment of 925 nucleotide sites obtained, the parsimony informative sites are 499 and occupy 54% of the total sites. The results indicate that the 1st intron sequences of the S7 r-protein gene in cyprinids are rich in informative sites and vary remarkably in sequence divergence from 2.3% between close species to 66.6% between distant species. The bootstrap values of the interior nodes in the NJ (neighbor-joining) and MP (most-parsimony) trees based on the present S7 r-protein gene data are higher thanWang, XZ He, SP Chen, YY 2002Chinese Science Bulletin2002,47,19:5

13Isolation of tomato proteinase inhibitor Ⅱ gene and the function of its intron显示文摘The genomic DNA sequence of tomato pro-teinase inhibitor II gene (named tin2i, whose accession number in GenBank is AF007240) was isolated by PCR techniques. The intron sequence (TPI), with a length of 109 bp, owns typical structures of GT/AG dinucieotides at both ends and high content of AT base pairs which accounts for 80.7% of the total nucleotides. As shown by recombination experiment, the TPI sequence could efficiently promote the expression of the reporter gene gusA and this effect was independent of the position and orientation of the intron, thus showing its role as an enhancer. Such experiments as gel retardation assays, GUS histochemical staining and GUS fluorometric assays further demonstrated that TPI sequence maybe has promoter-like activity.Xie, XZ Wu, NH 2002Chinese Science Bulletin2002,47,10:2

15Design,synthesis,and anti-inflammatory evaluation of a series of novel amino acid-binding 1,5-diarylpyrazole derivatives显示文摘Aim: To design and synthesize a series of novel amino acid-binding 1,5-diarylpyrazole derivatives, which are intended to act as prodrugs with better aqueous solubility than celecoxib, and which will exert potent anti-inflammatory activi-ties after being converted to their parent compounds in vivo. Methods: To introduce an amino acid, celecoxib analogs containing amino or methylamino group were synthesized first through multi-step chemical reactions. All the synthesized compounds were screened in an intact cell-based assay in vitro and in carrageenan-induced mouse paw edema in vivo. Some active compounds were selected for further evaluation in a carrageenan-induced rat paw edema model. The preliminary pharmacokinetics experiments were conducted using high performance liquid chromatography/mass spectrometry (HPLC/MS). Results: Celecoxib, 6 of the 1,5-diarylpyrazole class of celecoxib analogs, and their amino acid derivatives (hydrochloride salts) were synthesized. In vitro screening, the hydrochloride salts showed decreased inhibitory effects on cyclooxygenase (COX)- 1 and COX-2 compared with their parent compounds, but some exhibited potent anti-inflammatory activity in vivo. Compound 4a was selected for further evaluation, and its anti-inflammatory effect was equivalent to that of celecoxib after oral administration in the carrageenan-induced rat paw edema model. At three doses (25 mg/kg, 50 mg/kg, and 100 mg/kg) the percentage inhibition on edema was 20.7%, 52.6%, and 62.6% (for compound 4a) and 27.8%, 38.4%, and 40.1% (for celecoxib), respectively. Preliminary pharmacokinetic evaluations support the hypothesis that compound 4a was actually converted to its parent compound, compound 4. Conclusion: The compound bound with amino acid acts like prodrug, which can exert anti-inflammatory effect similar to celecoxib after being converted to its parent compound. This finding will be of great benefit in carrying out structural modifications of prodrug-like selective COX-2 inhibitors.Li MH Yin LL Cai MJ Zhang WY Huang Y Wang X Zhu XZ Shen JK 2005Acta Pharmacologica Sinica2005,26,7:2
