| 1 | Inuence of oxytetracycline on the structure and activity of microbial community in wheat rhizosphere soil显示文摘The microbial community composition in wheat rhizosphere was analyzed by detecting colony forming units (CFUs) in agar plates. The total CFUs in rhizosphere were 1.04 × 109/g soil with 9.0 × 108/g bacteria, 1.37 × 108/g actinomyces and 3.6 × 106/g fungi. The 10 dominant bacteria were isolated from wheat rhizosphere and were grouped into genus Bacillus according to their full length 16S rRNA gene sequences. Although belonging to the same genus, the isolated strains exhibited dierent sensitivities to oxytetracycline. When a series of the rhizosphere soil was exposed under various concentrations of oxytetracycline, the microbial community structure was highly aected with significant decline of CFUs of bacteria and actinomyces (22.2% and 31.7% at 10 mg/kg antibiotic, respectively). This inhibition was clearly enhanced with the increase exposure dosage of antibiotic and could not be eliminated during 30 d incubation. There was no obvious inuence of this treatment on fungi population. Among the four soil enzymes (alkaline phosphatase, acidic phosphatase, dehydrogenase and urease), only alkaline phosphatase was sensitive to oxytetracycline exposure with 41.3% decline of the enzyme activity at 10 mg/kg antibiotic and further decrease of 64.3%-80.8% when the dosage over 30 mg/kg. | YANG Qingxiang, ZHANG Jing, ZHU Kongfang, ZHANG Hao College of Life Sciences, Henan Normal University, Xinxiang 453007, China. | 2009 | Journal of Environmental Sciences2009，21，7： | 36 |

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(P | Guo 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. | 2001 | World Journal of Gastroenterology2001，7，3： | 20 |
| 4 | Roux-en-Y gastric bypass promotes expression of PDX-1 and regeneration of β-cells in Goto-Kakizaki rats显示文摘AIM:To study the effects of Roux-en-Y gastric bypass(RYGB) on the expression of pancreatic duodenal homeobox-1(PDX-1) and pancreatic β-cell regeneration/neogenesis,and their possible mechanisms in diabetics.METHODS:Three groups of randomly selected nonobese diabetic Goto-Kakizaki(GK) rats were subjected to RYGB,sham-RYGB and sham-operation(sham-op) surgery,respectively.The rats were euthanized at postoperative 1,2,4 and 12 wk.Their pancreases were resected and analyzed using reverse transcription polymerase chain reaction to detect the mRNA of PDX-1.Anti-PDX-1 immunohistochemical(IHC) staining and Western blotting were used to detect the protein of PDX-1.Double IHC staining of anti-Brdu and-insulin was performed to detect regenerated β-cells.The index of double Brdu and insulin positive cells was calculated.RESULTS:In comparison with sham-RYGB and sham-op groups,a significant increase in the expressions of PDX-1 mRNA in RYGB group was observed at all experimental time points(1 wk:0.378 ± 0.013 vs 0.120 ± 0.010,0.100 ± 0.010,F = 727.717,P < 0.001;2 wk:0.318 ± 0.013 vs 0.110 ± 0.010,0.143 ± 0.015,F = 301.509,P < 0.001;4 wk:0.172 ± 0.011 vs 0.107 ± 0.012,0.090 ± 0.010,F = 64.297,P < 0.001;12 wk:0.140 ± 0.007 vs 0.120 ± 0.010,0.097 ± 0.015,F = 16.392,P < 0.001);PDX-1 protein in RYGB group was also increased significantly(1 wk:0.61 ± 0.01 vs 0.21 ± 0.01,0.15 ± 0.01,F = 3031.127,P < 0.001;2 wk:0.55 ± 0.00 vs 0.15 ± 0.01,0.17 ± 0.01,F = 3426.455,P < 0.001;4 wk:0.39 ± 0.01 vs 0.18 ± 0.01,0.22 ± 0.01,F = 882.909,P < 0.001;12 wk:0.41 ± 0.01 vs 0.20 ± 0.01,0.18 ± 0.01,F = 515.833,P < 0.001).PDX-1 mRNA and PDX-1 protein production showed no statistical significance between the two sham groups.Many PDX-1 positive cells could be found in the pancreatic islets of the rats in RYGB group at all time points.In addition,the percentage of Brdu-insulin double staining positive cells was higher in RYGB group than in the other two groups(1 wk:0.22 ± 0.13 vs 0.03 ± 0.06,0.03 ± 0.06,P < 0.05;2 wk:0.28 ± 0.08 vs 0.00 ± 0.00,0.03 ± 0.06,P < 0.05;4 wk:0.24 ± 0.11 vs 0.07 ± 0.06,0.00 ± 0.00,P < 0.001;12 wk:0.20 ± 0.07 vs 0.03 ± 0.06,0.00 ± 0.00,P < 0.05).CONCLUSION:RYGB can increase the expression of pancreatic PDX-1 and induce the regeneration of β-cells in GK rats.The associated regeneration of islet cells may be a possible mechanism that how RYGB could improve type 2 diabetes mellitus. | Zhen Li,Dong-Fei Li,Jing-Xing Dai,Yu Bai,Lin Yuan,Southern Medical University,Institute of Basic Medical Anatomy National Key Disciplines,Guangzhou 510515,Guangdong Province,China Hong-Ya Zhang,Lu-Xian Lv,Wen-Qiang Li,Second Affiliated Hospital,Xinxiang Medical College,Henan Province Key Laboratory of Biological Psychiatry,Xinxiang 453002,Henan Province,China Ou Sha,Department of Anatomy,Faculty of Medicine,Shenzhen University,Shenzhen 518060,Guangdong Province,China | 2010 | World Journal of Gastroenterology2010，16，18： | 14 |

| 6 | Identification of an avirulence gene,avrxa5,from the rice pathogen Xanthomonas oryzae pv.oryzae显示文摘Xanthomonas oryzae pv.oryzae,the causal agent of bacterial blight in rice,interacts with rice plants in a gene-for-gene manner.The specificity of the interaction is dictated by avirulence(avr) genes in the pathogen and resistance(R) genes in the host.To date,no avr genes that correspond to recessive R genes have been isolated.We isolated an avrBs3/pthA family gene,avrxa5,from our previously isolated clone p58,which was originally from strain JXOIII.The avrxa5 gene converted the PXO99A strain from compatible to incompatible in rice cultivars containing the recessive xa5 gene,but not in those containing the dominant Xa5 gene.Sequencing indicated that avrxa5,which is highly similar to members of the avrBs3/pthA family,encodes a protein of 1238 amino acid residues with a conserved carboxy-terminal region containing three nuclear localization signals and a transcription activation domain.It has 19.5 34-amino-acid direct repeats,but the 13th amino acid is missing in the fifth and ninth repetitive units.Domain swapping of the repetitive regions between avrxa5 and avrXa7 changed the avirulence specificity of the genes in xa5 and Xa7 rice lines,respectively.This indicates that avrxa5 is distinct from previously characterized avrBs3/pthA members.The specificity of avrxa5 toward recessive xa5 in rice could help us better understand the molecular mechanisms of plant-pathogen specific interactions. | ZOU HuaSong1,ZHAO WenXiang2,ZHANG XiFu3,HAN YangChun2,ZOU LiFang2 & CHEN GongYou1,2* 1School of Agriculture and Biology,Shanghai Jiaotong University,Shanghai 200240,China 2College of Plant Protection,Nanjing Agricultural University/Laboratory for Monitoring and Management for Plant Pests and Diseases,Chinese Ministry of Agriculture,Nanjing 210095,China 3Department of Agronomy,Henan Vocation-Technical Teachers College,Xinxiang 453003,China | 2010 | Science China(Life Sciences)2010，53，12： | 9 |
| 7 | Heat shock induction of a 65 kDa ATP-binding proteinase in rat C6 glioma cells显示文摘The 45, 55, 65 and 100 kDa ATP-binding proteinases (ATP-BPases) of the heat-shocked (44 ℃ for 30 min, recovery for 12h) rat C6 glioma cells were purified by DEAE-ionexchange and ATP-affinity chromatography. Their molecular masses, isoelectric points (pI), pH-optima and other properties were analyzed by native proteinase gels.It was shown that the 65 kDa ATP-BPase is specifically induced by heat shock and not detectable in control cells.Its N-terminal 1-9 amino acid sequence was determined by Edman degradation, but no homologies to other proteins in the protein data bases were found. 30 and 31 kDa proteinases can be cleaved from the 45, 55 and 65 kDa proteinases to which they are linked. A possible relationship of the heat-induced 65 kDa ATP-BPase with the ATP-dependent proteinases (ATP-DPases) in prokaryotes and eukaryotes is discussed. | XU CUN SHUAN WEI MING ZHANG DIETER TECHEL MARCO MEYER YAN ZHANG LI LUDGER RENSING (Department of Biology, Henan Normal University,Xinxiang 453002)(Institute of Cell Biology, Bremen University, D-28359 Bremen, Germany) | 1999 | Cell Research1999，9，2： | 8 |

| 10 | Spatial calculating analysis model research of land-use change in urban fringe districts显示文摘The spatial calculating analysis model is based on GIS overlay. It compartmental-izes the research district land into three spatial parts: unchanged part,converted part and increased part. By this method we can evaluate the numerical model and dynamic degree model for existing calculating changing speed of land-use. Fur-thermore the paper raises reviving the calculating analysis model of spatial infor-mation in order to predict the dynamic changing level of all sorts of land. More concretely speaking,the model is mainly to know the changing area and changing speed (increased or decreased) of different land classifications from the micro-cosmic angle and to clearly show the spatial distribution and spatio-temporal law for changing urban lands. We discover why the situation has taken place by com-bining social and economic conditions. The result indicates that the calculating analysis model of spatial information can derive more accurate procedure of spatial transference and increase of all kinds of land from the microcosmic angle. By this model and technology,we can make the research of spatio-temporal structure evolution in land-use be more systematical and deeper. The result will benefit the planning management of urban land-use of developed districts in China in the fu-ture. | ZHANG XinChang,PAN Qiong,WANG ZhongYang & CHEN XinXiang Department of Remote Sensing and GIS Engineering,Sun Yat-sen University,Guangzhou 510275,China | 2008 | Science China(Technological Sciences)2008，51，S1： | 5 |

| 13 | Deposition features of Ni on self-assembled microtubule template from biolipid by electroless method显示文摘Diacetylenic glycero-phosphatidylcholine is a chiral molecule with amphiphilic property, and it can self-assembly into a lipid microtubular structure. The lipid microtubule is a stable structure formed by tightly wound helical ribbons, and the ribbon-wrapping patterns have a significant effect on their chemical deposition on the microtubules. The deposition of colloidal Pd catalyst occurs mainly on the helical edge of the wound helical ribbons to form helical deposition lines of colloidal Pd particles in the interior and exterior of the lipid microtubules, resulting in an uneven chemical deposition of Ni on the microtubules. Catalyzed by as-deposited colloidal Pd, metallized Ni microtubules are characterized by a helical form, which may be in relation to inner stress due to the thickness difference or the different deposition processes. The observation of microtom shows that metallized tubules have a hollow structure. Some metallized tubules have a kind of coaxial double layer structure observed in the direct experiment evidence, indicating that metallization can occur in the inner and outer surface of the lipid tubules. Both lipid microtubules and metallized microtubules can be used as vehicles for encapsulating biological active mole-cules to control their release and to develop micro-components in biological and mechanical systems. | FU Yubin1,2, ZHANG Lide1, ZHENG Jiyong2, FU Shangang3 & ZHU Mingwei3 1.

| 16 | Two hydroxypyruvate reductases encoded by OsHPR1 and OsHPR2 are involved in photorespiratory metabolism in rice显示文摘Mutations in the photorespiration pathway display a lethal phenotype in atmospheric air,which can be fully recovered by elevated CO2.An exception is that mutants of peroxisomal hydroxypyruvate reductase(HPR1)do not have this phenotype,indicating the presence of cytosolic bypass in the photorespiration pathway.In this study,we constructed overexpression of the OsHPR1 gene and RNA interference plants of OsHPR1 and OsHPR2 genes in rice(Oryza sativa L.cv.Zhonghua 11).Results from reverse transcription-polymerase chain reaction(RT-PCR),Western blot,and enzyme assays showed that HPR1 activity changed significantly in corresponding transgenic lines without any effect on HPR2 activity,which is the same for HPR2.However,metabolite analysis and the serine glyoxylate aminotransferase(SGAT)activity assay showed that the metabolitefiux of photorespiration was disturbed in RNAi lines of both HPR genes.Furthermore,HPR1 and HPR2proteins were located to the peroxisome and cytosol,respectively,by transient expression experiment.Double Research mutant hpr1 hpr2 was generated by crossing individual mutant of hpr1 and hpr2.The phenotypes of all transgenic lines were determined in ambient air and CO2-elevated air.The phenotype typical of photorespiration mutants was observed only where activity of both HPR1 and HPR2 were downregulated in the same line.Thesefindings demonstrate that two hydroxypyruvate reductases encoded by OsHPR1and OsHPR2 are involved in photorespiratory metabolism in rice. | Nenghui Ye Guozhen Yang Yan Chen Chan Zhang Jianhua Zhang Xinxiang Peng | 2014 | Journal of Integrative Plant Biology2014，56，2： | 2 |
| 17 | Potential of capillary electrophoresis mass spectrometry for the characterization and monitoring of amine-derivatized naphthenic acids from oil sands process-affected water显示文摘Capillary electrophoresis coupled to mass spectrometry(CE–MS) was used for the analysis of naphthenic acid fraction compounds(NAFCs) of oil sands process-affected water(OSPW). A standard mixture of amine-derivatized naphthenic acids is injected directly onto the CE column and analyzed by CE–MS in less than 15 min. Time of flight MS analysis(TOFMS), optimized for high molecular weight ions, showed NAFCs between 250 and 800 m/z. With a quadrupole mass analyzer, only low-molecular weight NAFCs(between 100 and 450 m/z) are visible under our experimental conditions. Derivatization of NAFCs consisted of two-step amidation reactions mediated by 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide(EDC), or mediated by a mixture of EDC and N-hydroxysuccinimide, in dimethyl sulfoxide, dichloromethane or ethyl acetate. The optimum background electrolyte composition was determined to be 30%(V/V) methanol in water and 2%(V/V) formic acid. NAFCs extracted from OSPW in the Athabasca oil sands region were used to demonstrate the feasibility of CE–MS for the analysis of NAFCs in environmental samples, showing that the labeled naphthenic acids are in the mass range of 350 to 1500 m/z. | Matthew S.MacLennan Cai Tie Kevin Kovalchik Kerry M.Peru Xinxiang Zhang John V.Headley David D.Y.Chen | 2016 | Journal of Environmental Sciences2016，28，11： | 2 |

| 20 | Identification of Rice Al-responsive Genes by Semi-quantitative Polymerase Chain Reaction using Sulfite Reductase as a Novel Endogenous Control显示文摘Based on the evidence that Al resistance is an inducible process and rice is an Al-resistant crop,identification of Al-responsive genes from rice may help to further clone Al-resistant genes in plants.Semi-quantitative and real-time polymerase chain reaction (PCR) is widely applied in gene transcriptional analyses,particularly for those genes with low transcript abundance.Normalization with proper endogenous control (EC) genes is critical for these two approaches in terms of reliability and precision.We first noticed that the expression of several commonly-used EC genes was depressed under Al stress,while sulfite reductase gene (SR) was stable throughout the Al treatment.The reliability of SR as an EC gene was further tested by analyzing the expression of a number of genes in response to Al challenge.Except for the consistent results obtained for the four previously-identified genes,nine additional genes were newly defined as Al-responsive in this study.Collectively,our results suggest that SR can be used as a novel EC gene for semi-quantitative and real-time PCR analysis of Al responsive genes,and that activated transport of silicon and stimulated metabolism of carotenoid and terpenoid could be involved in Al resistance in rice plants. | Jianjun Zhang Ying Yin Yuqi Wang Xinxiang Peng | 2010 | Journal of Integrative Plant Biology2010，52，5： | 1 |
