| 1 | Effect of substrate COD/N ratio on performance and microbial community structure of a membrane aerated biofilm reactor显示文摘Two parallel carbon-membrane aerated biofilm reactors were operated at well-defined conditions to investigate the effect of substrate COD/N ratios on the performance and microbial community structure of the bioreactor.Results showed that at substrate COD/N of 5,organic and nitrogen could be eliminated simultaneously,and COD removal degree,nitrification and denitrification efficiency reached 85%,93% and 92%,respectively.With increasing substrate COD/N ratios,the specific oxygen utilization rates of nitrifying bacteria in biofilm were found to decrease,indicating that nitrifying population became less dominant.At substrate COD/N ratio of 6,excessive heterotrophs inhibited the activity of nitrifying bacteria greatly and thus led to poor nitrification process.With the help of fluorescence in situ hybridization(FISH),Nitrosomonas and Nitrosospira were identified as dominant ammonia-oxidizing bacteria in the biofilm at substrate COD/N of 0,whereas only Nitrosospira were detected in the biofilm at COD/N ratio of 5.Nitrospira were present as dominant nitrite-oxidizing bacteria in our study.Confocal laser scanning microscopy images revealed that at substrate COD/N ratio of 0 nitrifying bacteria existed throughout the biofilm and that at COD/N ratio of 5 they were mainly distributed in the inner layer of biofilm. | Huijun Liu Fenglin Yang Shuyi Shi Xincheng Liu | 2010 | Journal of Environmental Sciences2010，22，4： | 9 |
| 2 | Effect of Ti-V-Nb-Mo addition on microstructure of high chromium cast iron显示文摘The effects of trace additions of multi-alloying elements(Ti,Nb,V,Mo)on carbides precipitation and as- cast microstructure of eutectic high chromium cast iron containing 2.85wt.%C and 31.0wt.%Cr were investigated from thermodynamic and kinetic considerations.The thermodynamic calculations show that Ti and Nb exist in the multi-alloying system in the forms of TiC and NbC.The formation of VC during the solidification is not feasible from the thermodynamic consideration.XRD analysis shows that the V exists in alloy compounds(VCr2C2,VCrFe8).The first precipitated high melting point particles(TiC,NbC)can act as the heterogeneous substrate of M7C3 carbides, which results in significant refinement of the M7C3 carbides.After the addition of alloying elements,C atom diffusion is hindered due to the strong affinities of the strong carbide forming elements for carbon,which decreases the growth rate of carbides.The combined roles of the increase of nucleation rate and the decrease of carbides growth rate lead to the finer microstructure. | Ma Youping Li Xiulan Liu Yugao Zhou Shuyi Dang Xiaoming | 2012 | China Foundry2012，9，2： | 6 |
| 3 | Fouling community characteristics in subtropical coastal waters of the southwestern East China Sea显示文摘A fouling study was conducted in coastal waters southwest of the East China Sea between December 2013 and November 2014. A total of 84 species of fouling organisms belonging to 69 genera, 49 families, and 10 phyla were recorded over the entire year. The community composition was dominated by coastal warm-water species belonging to typical subtropical inner bay communities. The prosperous stage of settlement lasted from April to September, and the adhesion strength of the fouling organisms was the highest in summer. Sessile suspension feeders constituted the main core of settlement for the fouling community. Amphibalanus reticulatus was the most dominant and representative species of fouling organism, and other dominant species included Caprella equilibra, Ectopleura crocea, Anthopleura nigrescens, Stylochus ijimai, Spirobranchus kraussii, Crassostrea angulata, Perna viridis, Jassa falcata, Stenothoe valida, Sphaerozius nitidus, and Biflustra grandicella. The individuals in the fouling community showed a mutual dependence or constraint relationship due to competition for settlement space and food, and they exhibited a particular spatiotemporal distribution in accordance with adaptation to environmental factors. Temperature was the most important environmental factor determining the geographic distribution of fouling organisms. The temperature characteristics of species essentially reflect the differences in the fouling community composition in various climate zones. The species number, settlement stage, and settlement rate of fouling organisms are closely related to water temperature. Local natural environmental conditions(salinity, water currents, light, etc.) as well as human activity(such as aquaculture production) are all important factors affecting the settlement of fouling organisms. | LIN Heshan WANG Jianjun LIU Wei LIU Kun ZHANG Shuyi HE Xuebao HUANG Yaqin LIN Junhui MOU Jianfeng ZHENG Chengxing YAN Tao | 2017 | Acta Oceanologica Sinica2017，36，10： | 6 |
| 4 | Atomistic simulation of dynamical and defect properties of multiferroic hexagonal YMnO_3显示文摘Atomistic simulation has been performed to investigate the dynamical and defect properties of multiferroic hexagonal YMnO3 with newly developed interaction potentials. Dynamical calculation reveals that phonon vibrations of hexagonal YMnO3 are quite different from those of orthorhombic YMnO3. Defect calculation finds that O Frenkel is the most probable intrinsic disorder, and Mn antisite defect is favorable to exist, especially for Mn ions entering the Y2 sites. It is also found that holes prefer to localize at O2sites rather than at Mn3+ sites, while the electron can be localized at the Mn3+ site. The disproportionation of Mn3+ ions is unlikely to occur in hexagonal YMnO3. | ZHANG ChengGuo ZHANG XiaoZhong SUN YongHao LIU ShuYi | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，5： | 4 |
| 5 | Effects on Growth Performance and Feed Digestibility of Hainan Black Pigs by Adding Lysine in Low Protein Diet显示文摘[Objective] The paper was to study the effects on growth performance and feed digestibility of Hainan black pigs by adding lysine in low protein diet.[Method] A total of 36 Hainan black pigs with the body weight of(46.34 ±3.06) kg were randomly divided into three groups:control group(protein level 15%,lysine level 0.83%),experimental group I(protein level 13%,0.83%),and experimental group II(protein level 13%,lysine level 1.03),each group had three replicates of four pigs.The trial lasted 35 d.[Result] The growth performance of Hainan black pig in group II had no significant difference with that in control group(P>0.05).The apparent digestibility of crude protein and phosphorus of Hainan black pigs in Group II increased significantly(P<0.05),which were increased by 10.08% and 11.85% respectively compared to the control group;the apparent digestibility of calcium was increased,but the difference was not significant(P>0.05).[Conclusion] It will not reduce the growth performance of Hainan black pig when the protein level of diet is reduced by 2% and the lysine level is increased to 1.03%.It is recommended that the diet can be used in the production of Hainan black pig. | Wei Limin Liu Quanwei Sun Ruiping Zheng Xinli Wang Feng Tan Shuyi Huang Lili Xing Manping | 2018 | Animal Husbandry and Feed Science2018，10，2： | 4 |
| 6 | An ecological survey of the abundance and diversity of benthic macrofauna in Indonesian multispecific seagrass beds显示文摘Seagrasses are one of the most productive ecosystems in coastal areas and support a wide variety of associated fauna. The tropical Indo-Pacific region is considered to have the highest diversity of seagrass plant species and the largest distribution areas of seagrass, yet the seagrass macrofauna in this region are poorly understood. To help fill this gap in our knowledge, an ecological survey was conducted to describe the abundance and diversity of benthic macrofauna from tropical seagrass beds and to determine between-station variations within a transect and between-site variations in macrofaunal abundance, taxa richness and community structure. Benthic macrofaunal samples associated with seagrass beds were collected with a core sampler on the east coast of North Sulawesi in May 2014 and on the west coast in October 2015. A total of 149 species from 14 higher taxa was collected. The most species-rich groups were polychaetes(56 species, 26% of total individual numbers), decapods(20 species, 9% of total numbers) and amphipods(18 species, 35% of total numbers). Between-station variations within a transect displayed different patterns between the east coast and the west coast. On the east coast, there were marked variations in abundance between stations within a transect for the macrofauna and amphipod assemblages. Both taxa richness and abundance varied with station for the macrofauna and polychaete assemblages on the west coast, resulting from the heterogeneity of the substrate along a transect. One-way ANOSIM together with MDS ordination indicated that macrofaunal community structure in seagrasses differed significantly between the east coast and the west coast, corresponding with the division of seagrasses into two broad categories of habitats, i.e.,mangrove-seagrass-reef continuum and seagrass-reef continuum. Compared with other studies in tropical areas,the abundance and diversity of benthic macrofauna in the present study were moderate. The reason for the two markedly distinct macrofaunal communities might be attributed to multiple factors, including sediment pattern,seagrass structure and temporal changes. | LIN Junhui HUANG Yaqin ARBI Ucu Yanu LIN Heshan AZKAB Muhammad Husni WANG Jianjun HE Xuebao MOU Jianfeng LIU Kun ZHANG Shuyi | 2018 | Acta Oceanologica Sinica2018，37，6： | 3 |

| 8 | Elliptical model for surface topography prediction in five-axis flank milling显示文摘In five-axis flank milling operations,the intersecting surfaces of different cutting edges create roughness on the milled surfaces that cannot be ignored in situations with strict requirements,especially in aeronautical manufacturing.To focus on motion problems in milling operations,this paper presents a new model that utilizes elliptical paths as cutting edge trajectories on 3D surface topography machined by peripheral milling.First,the cutter parallel axis offset and location angle are considered,which change the location of the ellipse center and intersection point of the cutting edges.Then,through the proposed model,the predicted surface topography is obtained,and the factors that affect the development tendency of roughness are analyzed.Next,the effects of the cutter location position(CLP)geometric parameters,cutter parallel axis offset and curvature on the roughness are evaluated by a numerical simulation.Finally,machining tests are carried out to validate the model predictions,and the results show that the surface topography predictions correspond well with the experimental results. | Liping WANG Shuyi GE Hao SIa Liwen GUAN Feiyu DUAN Yuzhe LIU | 2020 | Chinese Journal of Aeronautics2020，33，4： | 3 |
| 9 | E17110 promotes reverse cholesterol transport with liver X receptor β agonist activity in vitro显示文摘Liver X receptor(LXR) plays an important role in reverse cholesterol transport(RCT), and activation of LXR could reduce atherosclerosis. In the present study we used a cell-based screening method to identify new potential LXRβ agonists. A novel benzofuran-2-carboxylate derivative was identified with LXRβ agonist activity: E17110 showed a significant activation effect on LXRβ with an EC50 value of 0.72 μmol/L. E17110 also increased the expression of ATP-binding cassette transporter A1(ABCA1) and G1(ABCG1) in RAW264.7 macrophages. Moreover, E17110 significantly reduced cellular lipid accumulation and promoted cholesterol efflux in RAW264.7 macrophages. Interestingly, we found that the key amino acids in the LXRβ ligand-binding domain had distinct interactions with E17110 as compared to TO901317. These results suggest that E17110 was identified as a novel compound with LXRβ agonist activity in vitro via screening, and could be developed as a potential anti-atherosclerotic lead compound. | Ni Li Xiao Wang Peng Liu Duo Lu Wei Jiang Yanni Xu Shuyi Si | 2016 | Acta Pharmaceutica Sinica B2016，6，3： | 3 |
| 10 | Pharmacokinetics and Biodegradation of Chitosan in Rats显示文摘Chitosan, an excellent biomedical material, has received a widespread in vivo application. In contrast, its metabolism and distribution once being implanted were less documented. In this study, the pharmacokinetics and biodegradation of fluorescein isothiocyanate(FITC) labeled and muscle implantation administrated chitosan in rats were investigated with fluorescence spectrophotometry, histological assay and gel chromatography. After implantation, chitosan was degraded gradually during its distribution to diverse organs. Among the tested organs, liver and kidney were found to be the first two highest in chitosan content, which was followed by heart, brain and spleen. Urinary excretion was believed to be the major pathway of chitosan elimination, yet 80% of chitosan administered to rats was not trackable in their urine. This indicated that the majority of chitosan was degraded in tissues. In average, the molecular weight of the degradation products of chitosan in diverse organs and urine was found to be <65 k Da. This further confirmed the in vivo degradation of chitosan. Our findings provided new evidences for the intensive and safe application of chitosan as a biomedical material. | LI Hui JIANG Zhiwen HAN Baoqin NIU Shuyi DONG Wen LIU Wanshun | 2015 | Journal of Ocean University of China2015，14，5： | 3 |
| 11 | Identification of anti-Gram-negative bacteria agents targeting the interaction between ribosomal proteins L12 and L10显示文摘Gram-negative bacteria have become the main pathogens and cause serious clinical problems with increased morbidity and mortality. However, the slow discovery of new antimicrobial agents is unable to meet the need for the treatment of bacterial infections caused by drug-resistant strains. The interaction of L12 and L10 is essential for ribosomal function and protein synthesis. In this study, a yeast two-hybrid system was established to successfully detect the interaction between L12 and L10 proteins from gram-negative bacteria Escherichia coli, which allows us to screen compounds that specifically disrupt this interaction. With this system, we identified two compounds IMB-84 and IMB-87 that block L12-L10 interaction and show bactericidal activity against E. coli. We used glutathione-S-transferase(GST) pull-down and surface plasmon resonance(SPR) assays to demonstrate that these compounds disrupt L12-L10 interaction in vitro and the target of compounds was further confirmed by the overexpression of target proteins. Moreover, protein synthesis and elongation factor G-dependent GTPase activities are inhibited by two compounds. Therefore, we have identified two antibacterial agents that disrupt L12-L10 interaction by using yeast two-hybrid system. | Weiwei Wang Chao Liu Ningyu Zhu Yuan Lin JiANDong Jiang Yanchang Wang Yan Li Shuyi Si | 2018 | Acta Pharmaceutica Sinica B2018，8，5： | 3 |
| 12 | Flotation performance of a novel Gemini collector for kaolinite at low temperature显示文摘How to sustainably produce bauxite by effective reverse froth flotation of kaolinite at low temperature is an urgent problem to be solved in the field of mineral processing.In this work,a novel amino-based Gemini surfactant butadiyl-1,4-bis(dimethyl dodecylammonium bromide)(BBDB) was prepared and first utilized as a novel collector for kaolinite flotation.Its flotation performance for kaolinite was compared with that of the common monomolecular surfactant 1-dodecylamine(DDA) by micro-flotation tests.The tests results indicated that 95% kaolinite recovery was obtained using 2.0×10^(-4) mol/L BBDB at 25℃ which was half of the dosage when DDA obtained the maximum kaolinite recovery of81%.At extremely low temperature(0℃),3.0×10^(-4) mol/L BBDB could still collect 91% kaolinite,while DDA showed a frustrating ability.The contact angle tests indicated that BBDB could still significantly improve the hydrophobicity of the kaolinite surface(contact angle 71.7°) than DDA(contact angle only25.8°) at 0℃.The Krafft point comparison tests indicated that BBDB had a much lower Krafft point(below0℃) than DDA.Fourier transform infrared spectroscopy(FTIR)-spectrum analysis and zeta potential measurements showed that BBDB was physically adsorbed on the surface of kaolinite through electrostatic interaction. | Shiyong Zhang Zhiqiang Huang Hongling Wang Rukuan Liu Chen Cheng Shuyi Shuai Yajing Hu Zhiqun Guo Xinyang Yu Guichun He Weng Fu | 2021 | International Journal of Mining Science and Technology2021，31，6： | 2 |
| 13 | The novel ER stress inducer Sec C triggers apoptosis by sulfating ER cysteine residues and degrading YAP via ER stress in pancreatic cancer cells显示文摘Pancreatic adenocarcinoma(PAAD) is one of the most lethal malignancies. Although gemcitabine(GEM) is a standard treatment for PAAD, resistance limits its application and therapy. Secoemestrin C(Sec C) is a natural compound from the endophytic fungus Emericella, and its anticancer activity has not been investigated since it was isolated. Our research is the first to indicate that Sec C is a broad-spectrum anticancer agent and could exhibit potently similar anticancer activity both in GEM-resistant and GEM-sensitive PAAD cells. Interestingly, Sec C exerted a rapid growth-inhibiting effect(80% death at 6 h), which might be beneficial for patients who need rapid tumor shrinkage before surgery. Liquid chromatography/mass spectrometry and N-acetyl-L-cysteine(NAC) reverse assays show that Sec C sulfates cysteines to disrupt disulfide-bonds formation in endoplasmic reticulum(ER) proteins to cause protein misfolding, leading to ER stress and disorder of lipid biosynthesis. Microarray data and subsequent assays show that ER stress-mediated ER-associated degradation(ERAD) ubiquitinates anddownregulates YAP to enhance ER stress via destruction complex(YAP-Axin-GSK-βTr CP), which also elucidates a unique degrading style for YAP. Potent anticancer activity in GEM-resistant cells and low toxicity make Sec C a promising anti-PAAD candidate. | Junxia Wang Minghua Chen Mengyan Wang Wenxia Zhao Conghui Zhang Xiujun Liu Meilian Cai Yuhan Qiu Tianshu Zhang Huimin Zhou Wuli Zhao Shuyi Si Rongguang Shao | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 2 |

| 15 | Effect of Pelleted Total Mixed Ration of Different Particle Sizes on Production Performance and Serum Biochemical Index of Fattening Hainan Black Goats显示文摘[Objective] The paper to investigate the effects of pelleted total mixed ration of different particle size on production performance and serum biochemical index of fattening Hainan black goats.[Method] Thirty-six fattening Hainan black goats with the same genetic backgrounds and similar initial weight of(19.02±0.22) kg were randomly divided into three treatments. Goats were fed with Juncao+concentrate(control group), pel-leted total mixed ration I(particle size 6 mm, experimental group I) and II(particle size 5 mm, experimental group II), respectively. The trial lasted 45 d.[Result](1) The final weight and daily gain of experimental group II were significantly higher than those of control group( P<0.05), and the daily gain of experimental group II was also higher than that of experimental group I(P<0.05);the feed intake of experimental group II was markedly higher than that of control group(P<0.05), but was significantly lower than that of experimental group I(P<0.05). The feed/gain ratio of experimental group II was significantly lower than those of control group and experimental group I(P<0.05).(2) The feed gain cost of experimental group II was markedly lower than that of control group(P<0.05), but the gross profit was significantly higher than those of control group and experimental group I(P<0.05).(3) Compared with the control group, the serum total protein content of experimental group II increased markedly( P<0.05) while the urea nitrogen level decreased(P>0.05).[Conclusion] The pelleted total mixed ration with the particle size of 5 mm obtained better fattening ef-fect, and obviously improved the serum total protein level. | Liu Quanwei Wei Limin Wang Feng Tan Shuyi Sun Ruiping Huang Lili Zheng Xinli | 2019 | Animal Husbandry and Feed Science2019，11，1： | 2 |

| 17 | A general and simple method for evaluating the electrical transport performance of graphene by the van der Pauw–Hall measurement显示文摘Expected for many promising applications in the field of electronics and optoelectronics, a reliable method for the characterization of graphene electrical transport properties is desired to predict its device performance or provide feedback for its synthesis.However, the commonly used methods of extracting carrier mobility from graphene field effect transistor or Hall-bar is time consuming, expensive, and significantly affected by the device fabrication process other than graphene itself.Here we reported a general and simple method to evaluate the electrical transport performance of graphene by the van der Pauw–Hall measurement.By annealing graphene in vacuum to remove the adsorbed dopants and then exposing it in ambient surroundings, carrier mobility as a function of density can be measured with the increase of carrier density due to the dopant re-adsorption from the surroundings.Further, the relationship between the carrier mobility and density can be simply fitted with a power equation to the first level approximation, with which any pair of measured carrier mobility and density can be normalized to an arbitrary carrier density for comparison.We experimentally demonstrated the reliability of the method, which is much simpler than making devices and may promote the standard making for graphene characterization. | Fangzhu Qing Yang Shu Linsen Qing Yuting Niu He Guo Shuyi Zhang Chunlin Liu Changqing Shen Wanli Zhang Samuel S.Mao Wenjuan Zhu Xuesong Li | 2018 | Science Bulletin2018，63，22： | 2 |
| 18 | High proportion strontium-doped micro-arc oxidation coatings enhance early osseointegration of titanium in osteoporosis by anti-oxidative stress pathway显示文摘The excessive accumulation of reactive oxygen species(ROS)under osteoporosis precipitates a microenvironment with high levels of oxidative stress(OS).This could significantly interfere with the bioactivity of conventional titanium implants,impeding their early osseointegration with bone.We have prepared a series of strontium(Sr)-doped titanium implants via micro-arc oxidation(MAO)to verify their efficacy and differences in osteoinduction capabilities under normal and osteoporotic(high OS levels)conditions.Apart from the chemical composition,all groups exhibited similar physicochemical properties(morphology,roughness,crystal structure,and wettability).Among the groups,the low Sr group(Sr25%)was more conducive to osteogenesis under normal conditions.In contrast,by increasing the catalase(CAT)/superoxide dismutase(SOD)activity and decreasing ROS levels,the high Sr-doped samples(Sr75% and Sr100%)were superior to Sr25% in inducing osteogenic differentiation of MC3T3-E1 cells and the M2 phenotype polarization of RAW264.7 cells,thus enhancing early osseointegration.Furthermore,the results of both in vitro cell co-culture and in vivo studies also showed that the high Sr-doped samples(especially Sr100%)had positive effects on osteoimmunomodulation under the OS microenvironment.Ultimately,the collated findings indicated that the high proportion Sr-doped MAO coatings were more favorable for osteoporosis patients in implant restorations. | Xinkun Shen Kai Fang Kendrick Hii Ru Yie Zixin Zhou Yiding Shen Shuyi Wu Yue Zhu Zhennan Deng Pingping Ma Jianfeng Ma Jinsong Liu | 2022 | Bioactive Materials2022，7，4： | 2 |

| 20 | A fully biodegradable polydioxanone occluder for ventricle septal defect closure显示文摘Ventricular septal defect(VSD)is one of the commonest congenital heart diseases(CHDs).Current occluders for VSD treatment are mainly made of nitinol,which has the risk of nickel allergy,persistent myocardial abrasion and fatal arrythmia.Herein,a fully biodegradable polydioxanone(PDO)occluder equipped with a shape line and poly-L-lactic acid PLLA membranes is developed for VSD closure without the addition of metal marker.PDO occluder showed great mechanical strength,fatigue resistance,geometry fitness,biocompatibility and degradability.In a rat subcutaneous implantation model,PDO filaments significantly alleviated inflammation response,mitigated fibrosis and promoted endothelialization compared with nitinol.The safety and efficacy of PDO occluder were confirmed in a canine VSD model with 3-year follow-up,demonstrating the biodegradable PDO occluder could not only effectively repair VSD,induce cardiac remodeling but also address the complications associated with metal occluders.Furthermore,a pilot clinical trial with five VSD patients indicated that all the occluders were successfully implanted under the guidance of echocardiography and no adverse events occurred during the 3-month follow-up.Collectively,the fully bioresorbable PDO occluder is safe and effective for clinical VSD closure and holds great promise for the treatment of structural CHDs. | Zefu Li Pengxu Kong Xiang Liu Shuyi Feng Wenbin Ouyang Shouzheng Wang Xiaopeng Hu Yongquan Xie Fengwen Zhang Yuxin Zhang Rui Gao Weiwei Wang Xiangbin Pan | 2023 | Bioactive Materials2023，，6： | 1 |
