| 1 | Spatiotemporal changes in vegetation coverage and its driving factors in the Three-River Headwaters Region during 2000-2011显示文摘The Three-River Headwaters Region(TRHR), which is the source area of the Yangtze River, Yellow River, and Lancang River, is of key importance to the ecological security of China. Because of climate changes and human activities, ecological degradation occurred in this region. Therefore, 'The nature reserve of Three-River Source Regions' was established, and 'The project of ecological protection and construction for the Three-River Headwaters Nature Reserve' was implemented by the Chinese government. This study, based on MODIS-NDVI and climate data, aims to analyze the spatiotemporal changes in vegetation coverage and its driving factors in the TRHR between 2000 and 2011, from three dimensions. Linear regression, Hurst index analysis, and partial correlation analysis were employed. The results showed the following:(1) In the past 12 years(2000–2011), the NDVI of the study area increased, with a linear tendency being 1.2%/10a, of which the Yangtze and Yellow River source regions presented an increasing trend, while the Lancang River source region showed a decreasing trend.(2) Vegetation coverage presented an obvious spatial difference in the TRHR, and the NDVI frequency was featured by a bimodal structure.(3) The area with improved vegetation coverage was larger than the degraded area, being 64.06% and 35.94%, respectively during the study period, and presented an increasing trend in the north and a decreasing trend in the south.(4) The reverse characteristics of vegetation coverage change are significant. In the future, degradation trends will be mainly found in the Yangtze River Basin and to the north of the Yellow River, while areas with improving trends are mainly distributed in the Lancang River Basin.(5) The response of vegetation coverage to precipitation and potential evapotranspiration has a time lag, while there is no such lag in the case of temperature.(6) The increased vegetation coverage is mainly attributed to the warm-wet climate change and the implementation of the ecological protection project. | LIU Xianfeng ZHANG Jinshui ZHU Xiufang PAN Yaozhong LIU Yanxu ZHANG Donghai LIN Zhihui | 2014 | Journal of Geographical Sciences2014，24，2： | 47 |
| 2 | Theoretical analysis and experimental investigation on flexural performance of steel reinforced ultrahigh toughness cementitious composite (RUHTCC) beams显示文摘UHTCC (ultrahigh toughness cementitious composite), which is a kind of ultrahigh toughness cemen- titious composites material, exhibits pseudo strain hardening feature when subjected to tension load, and has enormous ductility and prominent crack dispersal ability. Accordingly, UHTCC can improve mechanical behavior of ordinary concrete structure especially its durability, and has been regarded as historical breakthrough to traditional cementitious materials. In this paper, the study focuses on flexure behavior of steel reinforced beam made of UHTCC. Based on the plane section assumption, along with two equilibrium equations of force and moment, the formulae to calculate the flexural load capability for the reinforced ultrahigh toughness cementitious composite (RUHTCC) beam were developed under the assumption that the compression stress- strain relationship in the UHTCC material is a bilinear model. Following this, the simplified formulae were further evolved by effective rectangle stress distribution approach in order to facilitate design of practical engineering. Two effective parameters introduced in effective rectangle approach were determined. The mathematical expressions to evaluate limited rein- forcement ratio, flexural stiffness as well as ductility index were proposed, too. Last, two series of dif- ferent reinforcement ratios of the RUHTCC beams were tested in four-point flexure loading. For com- parison purposes, ordinary RC (reinforced concrete) beams also were prepared. Both moment curva- ture curves and load mid-span displacement curves were recorded and compared with the theoretical calculations. A good agreement between them was found, which validates the proposed theoretical formulae. For ductility index, a slightly big difference between the experimental values and the calcu- lated ones exists. The experimental results show that, compared to control RC beams, the RUHTCC beam can improve both flexural capacity and ductility index, and the degree of improvement will de- crease with the increase in the reinforcement ratio. Particularly, the results also reveal that lager crack width in control beams can be greatly reduced by formation of tightly-spaced fine cracks in UHTCC, which offers more durable structures. | XU ShiLang ZHANG XiuFang | 2009 | Science China(Technological Sciences)2009，52，4： | 18 |
| 3 | Adipose-derived mesenchymal stem cell transplantation promotes adult neurogenesis in the brains of Alzheimer's disease mice显示文摘In the present study,we transplanted adipose-derived mesenchymal stem cells into the hippocampi of APP/PS1 transgenic Alzheimer’s disease model mice.Immunofluorescence staining revealed that the number of newly generated(BrdU+)cells in the subgranular zone of the dentate gyrus in the hippocampus was significantly higher in Alzheimer’s disease mice after adipose-derived mesenchymal stem cell transplantation,and there was also a significant increase in the number of BrdU+/DCX+neuroblasts in these animals.Adipose-derived mesenchymal stem cell transplantation enhanced neurogenic activity in the subventricular zone as well.Furthermore,adipose-derived mesenchymal stem cell transplantation reduced oxidative stress and alleviated cognitive impairment in the mice.Based on these findings,we propose that adipose-derived mesenchymal stem cell transplantation enhances endogenous neurogenesis in both the subgranular and subventricular zones in APP/PS1 transgenic Alzheimer’s disease mice,thereby facilitating functional recovery. | Yufang Yan Tuo Ma Kai Gong Qiang Ao Xiufang Zhang Yao Gong | 2014 | Neural Regeneration Research2014，9，8： | 16 |
| 4 | Gradual solution heat treatment of AlSiCuMg cast alloys显示文摘The microstmcture characteristics of AlSiCuMg cast alloys were studied with different Cu content and the gradual solution treatment by DSC, SEM, TEM and mechanical method. The melting point of α(Al) + Si decreases and polynary eutectic phases with low melting point form with increase of Cu content. Gradual solution treatment includes two steps:solution treating near the melting point of polynary eutectic phase to take it dissolve first, and then increasing solution temperature to take the remainder copper intermetallics dissolved into o(Al). Grain boundaries melting can be avoided by gradual solution treatment, even the maximum solution temperature is above final solidification point, and the age hardening response increases correspondingly. | WANG Guiqing , BIAN Xiufang ,and ZHANG Junyan1) The Key Laboratory of Liquid Structure and Heredity of Materials, Ministry of Education, Shandong University, Jinan 250061, China2) Department of Material Science and Technology, Shandong Architectural Engineering Institute, Jinan 250014, China | 2003 | Rare Metals2003，22，4： | 13 |
| 5 | Differences in thermal effects of moxibustion at Zusanli(ST 36) and Hegu(LI 4) on various facial areas in healthy people显示文摘OBJECTIVE:To study the effects of temperature on different facial areas by suspended moxibustion at two points,Zusanli(ST 36) and Hegu(LI 4),and probe the phenomena underlying self-regulation in the human body after thermal stimulation.METHODS:Thirty healthy volunteers accepted moxibustion over Zusanli(ST 36) and Hegu(LI 4),and the order of moxibustion points was randomly determined.Moxibustion method:suspension of moxibustion over Zusanli(ST 36) and Hegu(LI 4) on both sides was performed using an ignited moxa stick stuck in a support for 20 min.Observation method:An infrared thermal image of the face was taken before and after suspended moxibustion using a CK350 medical infrared thermal imaging instrument.Data analysis:A thermal microscopic section view system(TMTSys) was used to analyze the change in temperature in special facial areas.Statistical analysis was carried out using SPSS 14.0 software.RESULTS:Before moxibustion was suspended,the facial thermal image showed a T-shaped thermal area related to the vascular distribution with even temperature and good symmetry on both sides.Suspended moxibustion over Zusanli(ST 36) have a very significant increase in temperature at the forehead,around the nose,at the corners of the mouth,and at the cheeks and lips(P<0.01).Suspended moxibustion over Hegu(LI 4) also have a significant(P<0.05) increase in temperature around the nose,the corners of the mouth,the cheeks,and lips,where has a new high temperature area was formed(P<0.01).Suspended moxibustion over Hegu(LI 4) raised the temperature at the middle point of the lips more obviously than did Zusanli(ST 36) in the same person,(P<0.05).After 10 min of moxibustion over Zusanli(ST 36) and Hegu(LI 4),the change in temperature in the facial area reached its peak value.CONCLUSIONS:Facial infrared thermography of healthy people revealed a T-shaped thermal area reflecting a physiological thermal area.Moxibustion over Zusanli(ST 36) or Hegu(LI 4) raised the temperature in this facial T-shaped thermal area.Hegu(LI 4) led to the formation of a new thermal area in the lips.The time required for moxibustion to regulate human body temperature was 10 min. | Yiling Yang Laixi Ji Gaobo Li Xiufang Deng Peisi Cai Ling Guan | 2012 | Journal of Traditional Chinese Medicine2012，32，3： | 13 |
| 6 | The role of ribosomal proteins in the regulation of cell proliferation, tumorigenesis, and genomic integrity显示文摘Ribosomal proteins(RPs), the essential components of the ribosome, are a family of RNA-binding proteins, which play prime roles in ribosome biogenesis and protein translation. Recent studies revealed that RPs have additional extra-ribosomal functions, independent of protein biosynthesis, in regulation of diverse cellular processes. Here, we review recent advances in our understanding of how RPs regulate apoptosis, cell cycle arrest, cell proliferation, neoplastic transformation, cell migration and invasion, and tumorigenesis through both MDM2/p53-dependent and p53-independent mechanisms. We also discuss the roles of RPs in the maintenance of genome integrity via modulating DNA damage response and repair. We further discuss mutations or deletions at the somatic or germline levels of some RPs in human cancers as well as in patients of Diamond-Blackfan anemia and 5q- syndrome with high susceptibility to cancer development. Moreover, we discuss the potential clinical application, based upon abnormal levels of RPs, in biomarker development for early diagnosis and/or prognosis of certain human cancers. Finally, we discuss the pressing issues in the field as future perspectives for better understanding the roles of RPs in human cancers to eventually benefit human health. | Xilong Xu Xiufang Xiong Yi Sun | 2016 | Science China(Life Sciences)2016，59，7： | 13 |
| 7 | Effects of Service Condition on Rolling Contact Fatigue Failure Mechanism and Lifetime of Thermal Spray Coatings——A Review显示文摘The service condition determines the Rolling Contact Fatigue(RCF) failure mechanism and lifetime under ascertain material structure integrity parameter of thermal spray coating. The available literature on the RCF testing of thermal spray coatings under various condition services is considerable; it is generally difficult to synthesize all of the result to obtain a comprehensive understanding of the parameters which has a great effect on a thermal spray coating's resistance of RCF. The effects of service conditions(lubrication states, contact stresses, revolve speed, and slip ratio) on the changing of thermal spray coatings' contact fatigue lifetime is introduced systematically. The effects of different service condition on RCF failure mechanism of thermal spray coating from the change of material structure integrity are also summarized. Moreover, In order to enhance the RCF performance, the parameter optimal design formula of service condition and material structure integrity is proposed based on the effect of service condition on thermal spray coatings' contact fatigue lifetime and RCF failure mechanism. The shortage of available literature and the forecast focus in future researches are discussed based on available research. The explicit result of RCF lifetime law and parameter optimal design formula in term of lubrication states, contact stresses, revolve speed, and slip ratio, is significant to improve the RCF performance on the engineering application. | CUI Huawei CUI Xiufang WANG Haidou XING Zhiguo JIN Guo | 2015 | Chinese Journal of Mechanical Engineering2015，28，1： | 12 |

| 9 | Milling surface roughness for 7050 aluminum alloy cavity influenced by nozzle position of nanofluid minimum quantity lubrication显示文摘In nanofluid minimum quantity lubrication(NMQL)milling of aviation aluminum alloy,it is the bottleneck problem to adjust the position parameters(target distance,incidence angle,and elevation angle)of the nozzle to improve the surface roughness of milling,which has large and uncontrollable errors.In this paper,the influence law of milling cutter speed,helical angle,and cavity shape on the flow field around the milling cutter was studied,and the optimal nozzle profile parameters were obtained.Using 7050 aluminum alloy as the workpiece material,the milling experiment of the NMQL cavity was conducted by utilizing cottonseed oil-based Al2 O3 nanofluid.Results show that the high velocity of the surrounding air flow field and the strong gas barrier could be attributed to high rotating velocities of the milling cutter.The incidence angle of the nozzle was consistent with the helical angle of the milling cutter,the target distance was appropriate at 25–30 mm,and the elevation angle was suitable at 60°–65°.The range and variance analyses of the signal-to-noise ratio of milling force and roughness were performed,and the chip morphology was observed and analyzed.The results show that the optimal combination of nozzle position parameters was the target distance of 30 mm,the incidence angle of 35°,and the elevation angle of 60°.Among these parameters,target distance had the largest impact on cutting performance with a contribution rate of more than 55%,followed by incidence angle and elevation contribution rate.Analysis by orthogonal experiment revealed that the nozzle position parameters were appropriate,and Ra(0.087 lm)was reduced by 30.4%from the maximum value(0.125 lm).Moreover,Rsm(0.05 mm)was minimum,which was 36%lower than that of the seventh group(Rsm=0.078 mm). | Zhenjing DUAN Changhe LI Yanbin ZHANG Lan DONG Xiufang BAI Min YANG Dongzhou JIA Runze LI Huajun CAO Xuefeng XU | 2021 | Chinese Journal of Aeronautics2021，34，6： | 10 |
| 10 | Infrared thermography and meridian-effect evidence and explanation in Bell's palsy patients treated by moxibustion at the Hegu (LI4) acupoint Overall regulation or a specific target?显示文摘Subjects with Bell's palsy and healthy individuals were treated with moxibustion thermal stimulation on the Hegu (LI4) acupoint; an infrared thermal imaging system was used to observe facial-temperature changes. Bell's palsy patients developed low or high temperatures at the affected side, with poor symmetry. Healthy people showed high temperatures on the forehead, medial angle of the eye, nasal ala and around the lips, but low temperatures on bilateral cheeks, thus forming a 'T-type hot area' in the face, with good temperature symmetry. Moxibustion treatment for 11 minutes significantly improved high asymmetry in temperature in the faces of Bell's palsy patients. This evidence indicates that moxibustion treatment on Hegu enables increases in facial temperatures in healthy people and Bell's palsy patients, especially around the lips. Moxibustion stimulation at the Hegu not only improves the global circulation but also has specific effects on the lips in Bell's palsy patients, but the underlying mechanism needs further investigation. | Ling Guan Gaobo Li Yiling Yang Xiufang Deng Peisi Cai | 2012 | Neural Regeneration Research2012，7，9： | 10 |
| 11 | A Simplified PCR-SSP Method for HLA-A2 Subtype in a Population of Wuhan,China显示文摘HLA-A2 is the most frequent HLA-A allele in all ethnic populations, and an important restriction element for peptide presentation to T cells in infectious disease and cancer. However, the HLA-A2 supertype consisting of up to 75 subtypes, mutation studies and analyses using cytotoxic T lymphocytes suggest the functional relevance of subtype-specific differences in HLA-A2 molecules for peptide binding and T-cell recognition. Therefore, it is necessary for T-cell response study to discriminate the HLA-A2 subtypes and to understand the profile of HLA-A2 allelic distribution in a given population. In this study, we developed a simple, robust approach based on the nested polymerase chain reaction using sequence-specific primers (PCR-SSP) to discriminate 17 HLA-A2 subtypes which cover the most HLA-A2 alleles (> 99% allele frequency) reported in Chinese, using 15 combinations of 19 allelic specific primers. In the first round of PCR, 3 combinations of 5 primers were used to determine whether the tested sample was HLA-A2 positive, meanwhile the subtypes of HLA-A*0209 and HLA-A*0215N were determined for the variant position of these two subtypes is in exon 4 instead of exon 2, 3. Samples of HLA-A2 positive were subtyped in the second round of PCR, using PCR products of the first round as templates. This strategy was applied to test the samples of 78 random HLA-A2 positive individuals for their HLA-A2 subtypes. Those samples were screened for HLA-A2 positive by the first round PCR-SSP from 154 healthy blood donors in Wuhan, China. The subtyping results were verified by using flow cytometric analysis (FCM) with HLA-A2 specific monoclonal antibody BB7.2 and DNA sequencing. The typing results of the samples show 50.7% random individuals in the population carry HLA-A2, HLA-A*0201 ranks the first (allele frequency = 15.5%), followed by A*0207 (5.8%), A*0206 (4.7%), A*0203 (2.6%), A*0210 (0.7%), and these 5 alleles account for 99.0% HLA-A2 subtypes of allele frequency. Our study indicates that the developed typing method is simple and reliable for HLA-A2 subtyping in Chinese, and the profile of allelic distribution of HLA-A2 subtypes is revealed in the population of Wuhan, China. | Bing Liang Lijun Zhu Zhihui Liang Xiufang Weng Xiaoling Lu Cai'e Zhang Hui Li Xiongwen Wu | 2006 | Cellular & Molecular Immunology2006，3，6： | 9 |
| 12 | High-Resolution Genome-wide Association Study Identifies Genomic Regions and Candidate Genes for Important Agronomic Traits in Wheat显示文摘Wheat(Triticum aestivum)is a major staple food crop worldwide.Genetic dissection of important agronomic traits is essential for continuous improvement of wheat yield to meet the demand of the world's growing population.We conducted a large-scale genome-wide association study(GWAS)using a panel of 768 wheat cultivars that were genotyped with 327609 single-nucleotide polymorphisms generated by genotyping-by-sequencing and detected 395 quantitative trait loci(QTLs)for 12 traits under 7 environments.Among them,273 QTLs were delimited to≤1.0-Mb intervals and 7 of them are either known genes(Rht-D,Vrn-B1,and Vrn-D1)that have been cloned or known QTLs(TaGA2ox8,APO1,TaSus1-7B,and Rht12)that were previously mapped.Eight putative candidate genes were identified for three QTLs that enhance spike seed setting and grain size using gene expression data and were validated in three bi-parental populations.Protein sequence analysis identified 33 putative wheat orthologs that have high identity with rice genes in QTLs affecting similar traits.Large r^2 values for additive effects observed among the QTLs for most traits indicated that the phenotypes of these identified QTLs were highly predictable.Results from this study demonstrated that significantly increasing GWAS population size and marker density greatly improves detection and identification of candidate genes underlying a QTL,solidifying the foundation for large-scale QTL fine mapping,candidate gene validation,and developing functional markers for genomics-based breeding in wheat. | Yunlong Pang Chunxia Liu Danfeng Wang Paul St.Amand Amy Bernardo Wenhui Li Fang He Linzhi Li Liming Wang Xiufang Yuan Lei Dong Yu Su Huirui Zhang Meng Zhao Yunlong Liangi Hongze Jia Xitong Shen Yue Lu Hongming Jiang Yuye Wu Anfei Li Honggang Wang Lingrang Kong Guihua Bai Shubing Liu | 2020 | Molecular Plant2020，13，9： | 8 |
| 13 | Pre-peak on the structure factor of liquid hypoeutectic Al-Fe alloy显示文摘Using a θ-θ X ray diffractometer the structure of liquid hypoeutectic Al Fe alloy at 675℃ and its change with different thermal histories are investigated . Liquid Al is used as a reference system. It is found that a pre peak appears on the small angle part of the structure factor of the nonsuperheated hypoeutectic Al Fe alloy, but disappears after superheating whereas the structure factors of liquid Al hardly change with the different thermal histories, and no pre peak can be observed on them. The appearance of a pre peak is a mark of the intermediate range order (IRO). The pre peak is taken as the correlation between Fe atoms on the IRO length scale. Assume that the crystalline structure is the first order approximation of the liquid structure. A model structure is constructed. The basic unit is a cube formed by 8 Al atoms on its corner and one Fe atom occupying its center. The translation of such a unit along its fourbody diagonals by the length of a diagonal can meet the requirement of the Fe_Fe distance and gives a DO 3 like structure. If the vacancy among the units is filled with fcc like Al cells, the composition of the entity is about Al 7Fe, close to that of the metastable phase Al 6Fe from rapid solidification. It is speculated that there are Al 6Fe like clusters in the liquid hypoeutectic Al Fe alloy. | Jingyu Qin Xiufang Bian Weimin Wang Jiaji Ma Changye Xu | 1998 | Chinese Science Bulletin1998，43，14： | 7 |
| 14 | Influence of surface modification of SrFe12O19 particles with oleic acid on magnetic microsphere preparation显示文摘Oleic acid was used as surface modification agent to improve the hydrophobicity of magnetic strontium hexaferrite particles.The structure and properties of treated magnetic particles were characterized by scanning electronic microscopy(SEM),Fourier transform infrared spectra(FTIR),powder X-ray diffraction(XRD) and magnetic property measurement system(MPMS).The results show that oleic acid is chemically enwrapped on the surface of SrFe12O19 particles.Magnetic particles modified by oleic acid are highly dispersible and strongly responsive to magnetism but with slight decrease in saturated magnetization.The affinity between magnetic particles and monomers is improved by surface modification,resulting in increased particle incorporation in magnetic polymeric microspheres.The surface modification mechanism of magnetic particles by oleic acid is addressed in this work. | Sifang Kong Peipei Zhang Xiufang Wen Pihui Pi Jiang Cheng Zhuoru Yang Jing Hai | 2008 | Particuology2008，6，3： | 7 |
| 15 | The relationship between viscosity and glass forming ability of Al-(Ni)-Yb alloy systems显示文摘The dynamic viscosity of Al-Yb and Al-Ni-Yb superheated melts was measured using a torsional oscillation viscometer. The results show that the temperature dependence of viscosity fits the Arrhenius law well and the fitting factors are calculated. The amorphous ribbons of these alloys were produced by the melt spinning technique and the thermal properties were characterized by using a differential scanning calorimetry (DSC). E (the activation energy for viscous flow), which reflects the change rate of viscosity, has a good negative relation with the GFA in both Al-Yb and Al-Ni-Yb systems. However, there is no direct relation between liquidus viscosity (ηL) and GFA. The superheated fragility M can predict GFA in Al-Yb or Al-Ni-Yb alloy system. | JIA Ran, BIAN XiuFang, Lü XiaoQian, SONG KaiKai & LI XueLian Key Laboratory for Liquid-Solid Structural Evolution and Processing of Materials (Ministry of Education), Shandong University, Jinan 250061, China | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，3： | 6 |
| 16 | Magnetically Driven Superhydrophobic Polyurethane Sponge for High Efficiency Oil/Water Mixtures Separation显示文摘Magnetically driven super-hydrophobic materials were prepared by Fe3O4 nanoparticles and stearic acid,which were deposited on the surface of polyurethane sponges.The presence of the Fe3O4 nanoparticles makes the sponge have the magnetic,and the micro-nano hierarchical structure and hydrophobic functional groups lead to the sponge have excellent superhydrophobicity.The as-prepared sponge exhibited excellent absorption capacities for various oils and organic solvents ranging from 23.8 times to 86.7 times of its own weight.Moreover,the oil separation capacities still keep a high value after 50 cycles of squeezing the saturated absorbed as-prepared sponge.All of these satisfactory properties make the as-prepared sponge as a candidate of ideal absorbents for oily industrial wastewater and oil spills in oceans. | Xuemei Zhang Feng Fu Xiaoming Gao Xiufang Hou | 2019 | Journal of Bionic Engineering2019，16，1： | 6 |
| 17 | Influence of La2O3 addition on nano indentation hardness and residual stress of Stellite 6 coating prepared by plasma cladding显示文摘One of the problems limiting the application of Stellite 6 coating is the residual stress resulting in cracks in the coating easily. In order to reduce the residual stress and increase the nano-indentation hardness,La_2 O_3 was added to Stellite 6 coating in this study, and the influence on the microstructure, nano indentation hardness and residual stress of the coatings were investigated by scanning electron microscopy(SEM) with energy dispersive spectrum(EDS), X-ray diffraction(XRD) and nano-indentation tester. Results indicate that the addition of La_2 O_3 leads to the phenomenon that the dendrite is partly transformed into the equiaxed grain, which results in the grain refinement. The nano-indentation hardness of coatings is improved, which is attributed to the fine-grain strengthening and dispersion strengthening effect of La_2 O_3. With the addition of La_2 O_3, the residual stress in coatings is decreased significantly. Especially, when the content of La_2 O_3 is 0.8 wt%, the nano indentation hardness increases by 1.31 times and residual stress decreases to 20 percent, compared with coating without La_2 O_3. | Yongchao Fang Xiufang Cui Zhaobing Cai Chang Wang Guo Jin | 2018 | Journal of Rare Earths2018，36，8： | 5 |
| 18 | Amyloid beta-peptide worsens cognitive impairment following cerebral ischemia-reperfusion injury显示文摘Amyloid β-peptide,a major component of senile plaques in Alzheimer’s disease,has been implicated in neuronal cell death and cognitive impairment.Recently,studies have shown that the pathogenesis of cerebral ischemia is closely linked with Alzheimer’s disease.In this study,a rat model of global cerebral ischemia-reperfusion injury was established via occlusion of four arteries;meanwhile,fibrillar amyloidβ-peptide was injected into the rat lateral ventricle.The Morris water maze test and histological staining revealed that administration of amyloidβ-peptide could further aggravate impairments to learning and memory and neuronal cell death in the hippocampus of rats subjected to cerebral ischemia-reperfusion injury.Western blot showed that phosphorylation of tau protein and the activity of glycogen synthase kinase 3βwere significantly stronger in cerebral ischemia-reperfusion injury rats subjected to amyloid β-peptide administration than those undergoing cerebral ischemia-reperfusion or amyloidβ-peptide administration alone.Conversely,the activity of protein phosphatase 2A was remarkably reduced in rats with cerebral ischemia-reperfusion injury following amyloidβ-peptide administration.These findings suggest that amyloidβ-peptide can potentiate tau phosphorylation induced by cerebral ischemia-reperfusion and thereby aggravate cognitive impairment. | Bo Song Qiang Ao Ying Niu Qin Shen Huancong Zuo Xiufang Zhang Yandao Gong | 2013 | Neural Regeneration Research2013，8，26： | 5 |
| 19 | 基于桐油热处理的竹材理化性质研究显示文摘寻求绿色、可持续发展的改性方法来生产耐用竹材制品,是目前竹产业面临的挑战。本文将桐油热处理技术应用于竹材改性,探讨了桐油热处理过程中桐油在竹材中的渗透行为和分布,研究了桐油与热处理的协同作用对竹材化学性质、物理性质、力学性质的影响以及相互作用机制。结果表明,桐油热处理不仅可以增强竹材的疏水性能和尺寸稳定性,改善竹材的防霉性能,而且竹材可以保持其良好的力学性能。与未处理竹材相比,200℃桐油热处理后竹材的饱水膨胀率从3.17%下降至2.42%,200℃桐油热处理后竹材径切面的接触角在300 s时仍可保持在100°以上。桐油热处理后竹材性能的改善归因于竹材化学成分的变化、纤维结晶度的增加、竹材外表面和细胞腔内表面油膜的形成。因此,桐油热处技术在竹材工业改性中具有良好的发展前景。 | 费本华 唐彤 Tong Tang Bo Zhang Xianmiao Liu Wenbo Wang Xiufang Chen Benhua Fei | 2019 | 世界竹藤通讯2019，17，5： | 5 |
| 20 | Improved performance of aluminum pigments encapsulated in hybrid inorganic-organic films显示文摘An organic silane acrylate resin(PMBK) was synthesized by free-radical solution polymerization using methyl methacrylate,butyl acrylate and(3-methacryloxypropyl)trimethoxysilane as monomers.Aluminum(Al) particles were then encapsulated in inorganic-organic hybrid films that were prepared by hydrolysis and condensation of PMBK and tetraethyl orthosilicate(TEOS) on the surface of Al pigments.Characterization results showed that PMBK and TEOS could simultaneously hydrolyze and condense with hydroxyl groups on the surface of the Al particles to form composite Al particles coated with inorganic-organic hybrid films.Compared with raw Al particles,the corrosion resistance and adhesive properties of paint films containing the composite Al particles were improved greatly,while the glossiness of the paint films decreased slightly,from 48.6° to 47.0°.In alkaline media(pH 11),the volume of evolved H_2 of composite Al particles was only 3.5 mL,whereas that of raw Al was 83.5 mL.The glossiness of paint films containing composite Al particles decreased by 1.66%after immersion in alkaline media for24 h,whereas that of raw Al decreased by 14.82%.Peel-off tests of the paint films showed that the composite particles moved slightly away from the paint films.In contrast,the raw Al particles were seriously desquamated,suggesting encapsulation of hybrid films can greatly improve the adhesive properties of Al particles in paint films. | Pihui Pi Chao Liu Xiufang Wen Lianfu Zheng Shouping Xu Jiang Cheng | 2015 | Particuology2015，13，2： | 5 |
