2Effects of aminoguanidine on nitric oxide production induced by inflammatory cytokines and endotoxin in cultured rat hepatocytes显示文摘AIM To study the effects of aminoguanidine(AG) and two L-arginine analogues Nω-nitro-L-arginine methyl ester (L-NAME) and Nω-nitro-L-arginine (L-NNA) on nitric oxide (NO) productioninduced by cytokines (TNF-α, IL-11β, and IFN-γ)and bacterial lipopolysaccharide (LPS) mixture(CM) in the cultured rat hepatocytes, andexamine their mechanisms action.METHODS Rat hepatocytes were incubatedwith AG, L-NAME, L-NNA, Actinomycin D (ActD)and dexamethasene in a medium containing CM(LPS plus TNF-α, IL-1β, and IFN-γ) for 24 h. NOproduction in the cultured supernatant wasmeasured with the Griese reaction. IntracellularcGMP level was detected with radioimmunoasey.RESULTS NO production was markedlyblocked by AG and L-NAME in a dose-dependentmanner under inflammatory stimuli conditiontriggered by CM in vitro. The rate of themaximum inhibitory effects of L-NAME (38.9%)was less potent than that obtained with AG(53.7%, P<0.05). There was no significantdifference between the inhibitory effects of AGand two L-arginine analogues on intracellularcGMP accumulation in rat cultured hepatocytes.Non-specific NOS expression inhibitordexamethasone ( DEX ) and iNOS mRNAtranscriptional inhibitor ActD also significantlyinhibited CM-induced NO production. AG(0.1mmol.L-1) and ActD (0.2ng@Lt) wereequipotent in decreasing NO production inducedby inflammatory stimuli in vitro, and botheffects were more potent than that induced bynon-selectivity NOS activity inhibitor L-NAME(0. 1 mmol@ L- 1) under similar stimuli conditions(PGuo Liang Zhang Ye Hong Wang Hui Ling Teng Zhi Bin Lin Department of Pharmacology,School of Basic Medical Sciences,Beijing University,Beijiog 100083,ChinaDr.Guo Liang Zhang graduated from Xinxiang Medical College in 1982,got Ph.D.at Nagoya City University Medical School,Japan in 1994,finished postdoctoral research at Beijing Medical Univcrsity in 1996,now an associate professor of pharmacology,specialized in hepatic pharmacology,having 15 papers published. 2001World Journal of Gastroenterology2001,7,3:20

4Transretinoic acid inhibits rats gastric epithelial dysplasia induced by N-methyi-N-nitro-N-nitrosoguanidine:influences on cell apoptosis and expression of its regulatory genes显示文摘INTRODUCTIONGastric epithelial dysplasia (GED) hypothetically is a straight-forward concept: dysplastic epithelium replacing the normal gastric epithelium of the stomach [1].In the stomach ,like any other segment of the gut ,it is defined as an unequivocal non-invasive epithelial change[2,3].The observation of gastric dysplasia as a cancerous lesion was recognized over a century ago ,but it is only after the advent of gastroscopy that its clinical significance has been stressed[4-7].Ru Tao Cui~1 Gan Cai~2 Zhao Bao Yin~(2*) Yong Cheng~2 Qiu Hong Yang~1 Tao Tian~(3#) ~1Liver Center,Beijing Friendship Hospital Affiliated to CapitalUniversity of Medical Sciences~2Department of Gastroenterology,Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine,Shanghai China and Department of Pathophysiology.Shanghai Medical University.Shanghai,China ~3Pathological Department,Shanghai Medical University (?)Now working at UCLA,USA ~#Now working at University of Michigan,USADr.Ru Tao Cui graduated and got the bachelor degree from Shandong University of Traditional Chinese Medicine in 1994,got doctor degree from Shanghai University of Traditional Chinese Medicine in 2000,now studying as a postdoc,majoring gastroenterology,having 29 papers published. 2001World Journal of Gastroenterology2001,7,3:8
5The Relationship between Apolipoprotein B Gene Loci Polymorphisms and Coronary Heart Disease.显示文摘The authors utilized the polymerase chain reaction to rapidly and accurately type a variable number of tandemly repeated loci (VNTR loci) of the 3’ flanking region of apolipoprotein B (apo B) gene, and studied the relationship between this loci polymorphisms and coronary heart disease (CAD); comparisons were made with relative diseasesQu Wan-yun,et al.

6Changes of PTH, 1,25(OH)_2D_3 and Biochemistry in Renal Osteodystrophy.显示文摘The changes of plasma PTH, 1,25(OH)2D3, serum calcium, phosphorus and AKP were observed in 55 uremic patients with renal osteodystrophy. The results showed that: in all types of renal osteodystrophy, plasma PTH were markedly higher than normal (P<0.001), while plasma 1,25(OHH)2D3 and serum calcium were lower than normal (P<0.001). In low bone-turnover uremic osteodystrophy (LTO), plasma phosphorus was markedly lower than that of high bone-turnover uremic osteodystrophy (HTO) and mixe d uremic osteodystrophy (MO) (P<0.05), and plasma 1,25(OH)2D3 was significantly lower than that of HTO (P<0.05). In HTO and MO, serum phosphorus was much higher than mormal (P<0.001). Plasma PTH had a negative linear correlation with plasma 1,25(OH)2D3 (P<0.05), a positive linear correlation with serum AKP (P<0.05), but no linear correlation with the duration of hemodialysis, serum calcium, serum aluminum and bone aluminum content. Plasma 1.25(OH)2D3 had no linear correlation with the duration of hemodialysis,Jia Jing-kang, et al. Renal Unit, 2ndHospital, Zhejiang Med Uni, Hangzhou 310009.

7APPLICATION OF COMPUTER GRAPHICS IN MARTENSITIC TRANSFORMATION显示文摘This paper discuss the stereographic method of martensitic transformation(MT) in the viewof computer graphics(CG)and programs are programmed to realize this method.Habitplane resulting from the programs agrees with that of numerical analysis in terms of the lat-tice parameters of austenite and martensite and shear mechanism supposed inFe-22%Ni-0.8%C alloy,so does orientation relationships.Zhou JianqiSouthern Naval Unit of Institute of Naval Technical Equipment in Zhanjiang Manuscript received 18 April, 1994 1994Acta Metallurgica Sinica(English Letters)1994,7,2:3

9MICROSTRUCTURE OF Mg-Zn-Zr-Y ALLOYS显示文摘In the as-cast Mg-Zn-Zr-Y alloys.the quasierystal phases show massive and eutectoidplate morphologies.The selected area diffraction(SAD)revealed that a large part of the quasicrystals are face-centered icosahedral(FCI),while a small amout of the quasierystals belong to the simple icosahedral(SI)phase.It was found that in homogenized alloys,a part of the grain boundry phases was dissolved,and small massive W-phase and lath-shape MgZn2 phase dispersedly precipitate in the grains.The transformation of the quasicrystals relates to the temperature.After homogenizing at 360℃,the quasicrystals still present,while after homogenizing at 400℃,the quasicrystals transformed into a new C-typeorthorhombic phase with a=0.975nm,b=1.137nm and c=0.935nm.LUO Zhiping, ZHANG Shaoqing, SONG DeyuBeijing Institute of Aeronoutical Materials, Beijing, 100095, ChinaTANG Yali, ZHAO DongshanZhengzhou Institute of Technology, Zhengzhou, 450002, China Manuscript received, 27 April 1994 1994Acta Metallurgica Sinica(English Letters)1994,7,2:2
10ANALYSIS OF FLUID FIELD OF LIQUID METAL IN ELECTROMAGNETIC CENTRIFUGAL CASTING显示文摘Navier-Stokes equation and Lorentz force equation are used to calculate the fluid field of liquid metal of electromagnetic centrifugal casting(EMCC) in this paper.A field equationis given,which shows the azimuthal velocity closely relates to electrical conductivity,mag-netic density,viscosity of liquid metal and radius of casting.The results show that the sta-tionary magentic field can effectively restrain the fluid flow and the relative velocity be-tween liquid metal and casting mould and the velocity gradient at solid/liquid interface in-creases with rising magnetic density,which has a great effect on the solidification of liquidmetal and crystal growth characteristies.JIAO Yuning, LIU Qingmin, YANG Yuangsheng, HU Zhuangqi,Institute of Meta] Research, Chinese Academy of Sciences, Shenyang, ChinaGAO Yunyan, JIA Guanglin, ZHANG Guozhi, QIAO YuanjunNortheast University, Shenyang, China Manuscript received 12 May, 1994 1994Acta Metallurgica Sinica(English Letters)1994,7,2:2
