| 1 | Variation of grain Cd and Zn concentrations of 110 hybrid rice cultivars grown in a low-Cd paddy soil显示文摘Enhanced Cd uptake and Zn depletion in rice grains and high potential for food Cd exposure by the high-yielding hybrid cultivars of China had been addressed.A field experiment was conducted in 2006 to determine the difference in grain Cd and Zn between cultivars.Total 110 cultivars including super rice and common hybrid rice cultivars were grown on a single paddy soil(Entic Haplaquept) with a neutral reaction and low total Cd content.Grain Cd and Zn concentrations were determined with graphite atomic adsorption spectrophotometer(GFAAS) and flame atomic adsorption spectrophotometer(AAS) respectively.Wide variation of Cd content in grain was found in a range of 0.004-0.057 mg/kg,while the Zn content in a range of 10.25-30.06 mg/kg among the cultivars.Higher Cd but lower Zn concentration in grains of super rice cultivars was observed compared to the common hybrid ones.A highly significant positive linear correlation of grain Cd/Zn with grain Cd was found for super rice and common hybrid cultivars,meanwhile much higher slope for these hybrid cultivars than the reported non-hybrid cultivars was also observed.Using the limit value of the Chinese chemical guidelines for foods(MOHC and SSC,2005),calculated potential risk of food Cd exposure with 'Zn hungry' through diet intake was prominent with all the studied 110 hybrid rice cultivars,possessing high potential health problems for rice production in South China using the super rice cultivars.Breeding of genotypes of rice cultivars with low grain Cd and low Cd/Zn ratio is needed for rice production in acidic red soils where Cd bioavailability is prevalently high. | SHI Jing,LI Lianqing,PAN Genxing Institute of Resource,Ecosystem and Environment of Agriculture,Nanjing Agricultural University,Nanjing 210095,China. | 2009 | Journal of Environmental Sciences2009,21,2: | 44 |
| 2 | Perspectives on studies on soil carbon stocks and the carbon sequestration potential of China显示文摘Soil carbon stocks and sequestration have been given a lot of attention recently in the study of terrestrial ecosystems and global climate change.This review focuses on the progress made on the estimation of the soil carbon stocks of China,and the characterization of carbon dynamics of croplands with regard to climate change,and addresses issues on the mineralization of soil organic carbon in relation to greenhouse gas emissions.By integrating existing research data,China's total soil organic carbon(SOC) stock is estimated to be 90 Pg and its inorganic carbon(SIC) stock as 60 Pg,with SOC sequestration rates in the range of 20-25 Tg/a for the last two decades.An estimation of the biophysical potential of SOC sequestration has been generally agreed as being 2 Pg over the long term,of which only 1/3 could be attainable using contemporary agricultural technologies in all of China's croplands.Thus,it is critical to enhance SOC sequestration and mitigate climate change to improve agricultural and land use management in China.There have been many instances where SOC accumulation may not induce an increased amount of decomposition under a warming scenario but instead favor improved cropland productivity and ecosystem functioning.Furthermore,unchanged or even decreased net global warming potential(GWP) from croplands with enhanced SOC has been reported by a number of case studies using life cycle analysis.Future studies on soil carbon stocks and the sequestration potential of China are expected to focus on:(1) Carbon stocks and the sequestration capacity of the earths' surface systems at scales ranging from the plot to the watershed and(2) multiple interface processes and the synergies between carbon sequestration and ecosystem productivity and ecosystem functioning at scales from the molecular level to agro-ecosystems.Soil carbon science in China faces new challenges and opportunities to undertake integrated research applicable to many areas. | ZHENG JuFeng CHENG Kun PAN GenXing Pete SMITH LI LianQing ZHANG XuHui ZHENG JinWei HAN XiaoJun DU YanLing | 2011 | Chinese Science Bulletin2011,56,35: | 24 |

| 4 | Review of Electronic Speckle Pattern Interferometry(ESPI) for Three Dimensional Displacement Measurement显示文摘Three dimensional(3D)displacements,which can be translated further into 3D strain,are key parameters for design,manufacturing and quality control.Using different optical setups,phase-shift methods,and algorithms,several different 3D electronic speckle pattern interferometry(ESPI)systems for displacement and strain measurements have been achieved and commercialized.This paper provides a review of the recent developments in ESPI systems for 3D displacement and strain measurement.After an overview of the fundamentals of ESPI theory,temporal phase-shift,and spatial phase-shift techniques,3D deformation measurements by the temporal phase-shift ESPI system,which is suited well for static measurement,and by the spatial phase-shift ESPI system,which is particularly useful for dynamic measurement,are discussed.For each method,the basic theory,a brief derivation and different optical layouts are presented.The state of art application,potential and limitation of the ESPI systems are shown and demonstrated. | YANG Lianxiang XIE Xin ZHU Lianqing WU Sijin WANG Yonghong | 2014 | Chinese Journal of Mechanical Engineering2014,27,1: | 20 |
| 5 | Atomic force microscopy imaging and mechanical properties measurement of red blood cells and aggressive cancer cells显示文摘Mechanical properties play an important role in regulating cellular activities and are critical for unlocking the mysteries of life. Atomic force microscopy (AFM) enables researchers to measure mechanical properties of single living cells under physiological conditions. Here, AFM was used to investigate the topography and mechanical properties of red blood cells (RBCs) and three types of aggressive cancer cells (Burkitt's lymphoma Raji, cutaneous lymphoma Hut, and chronic myeloid leukemia K562). The surface topography of the RBCs and the three cancer cells was mapped with a conventional AFM probe, while mechanical properties were investigated with a microsphere glued onto a tip-less cantilever. The diameters of RBCs are significantly smaller than those of the cancer cells, and mechanical measurements indicated that Young's modulus of RBCs is smaller than those of the cancer cells. Aggressive cancer cells have a lower Young's modulus than that of indolent cancer cells, which may improve our understanding of metastasis. | LI Mi LIU LianQing XI Ning WANG YueChao DONG ZaiLi XIAO XiuBin ZHANG WeiJing | 2012 | Science China(Life Sciences)2012,55,11: | 16 |
| 6 | Effects of free iron oxyhydrates and soil organic matter on copper sorption-desorption behavior by size fractions of aggregates from two paddy soils显示文摘Effects of free iron oxyhydrates (Fed) and soil organic matter (SOM) on copper (Cu2+) sorption-desorption behavior by size fractions of aggregates from two typical paddy soils (Ferric-Accumulic Stagnic Anthrosol (Soil H) and Gleyic Stagnic Anthrosol (Soil W)) were investigated with and without treatments of dithionite-citrate-bicarbonate and of H2O2. The size fractions of aggregates were obtained from the undisturbed bulk topsoil using a low energy ultrasonic dispersion procedure. Experiments of equilibrium sorption and subsequent desorption were conducted at soil water ratio of 1:20, 25°C. For Soil H, Cu2+ sorption capacity of the DCB-treated size fractions was decreased by 5.9% for fine sand fraction, by 40.4% for coarse sand fraction, in comparison to 2.9% for the bulk sample. However, Cu2+ sorption capacities of the H2O2-treated fractions were decreased by over 80% for the coarse sand fraction and by 15% for the clay-sized fraction in comparison to 88% for bulk soil. For Soil W, Cu2+ sorption capacity of the DCB-treated size fraction was decreased by 30% for the coarse sand fraction and by over 75% for silt sand fraction in comparison to 44.5% for the bulk sample. Cu2+ sorption capacities of the H2O2-treated fractions were decreased by only 2.0% for the coarse sand fraction and by 15% for the fine sand fraction in comparison to by 3.4% for bulk soil. However, Cu2+ desorption rates were increased much in H2O2-treated samples by over 80% except the clay-sized fraction (only 9.5%) for Soil H. While removal of SOM with H2O2 tendend to increase the desorption rate, DCB- and H2O2-treatments caused decrease in Cu2+ retention capacity of size fractions. Particularly, there hardly remained Cu2+ retention capacity by size fractions from Soil H after H2O2 treatment except for clay-sized fraction. These findings supported again the dominance of the coarse sand fraction in sorption of metals and the preference of absorbed metals bound to SOM in di?erently stabilized status among the size fractions. Thus, enrichment and turnover of SOM in paddy soils may have great effects on metal retention and chemical mobility in paddy soils. | WANG Fang, PAN Genxing, LI Lianqing Institute of Resource, Ecosystem and Environment of Agriculture, Nanjing Agricultural University, Nanjing 210095, China. | 2009 | Journal of Environmental Sciences2009,21,5: | 14 |
| 7 | Source rupture process of Lushan M_S7.0 earthquake, Sichuan,China and its tectonic implications显示文摘The source rupture process of the MS7.0 Lushan earthquake was here evaluated using 40 long-period P waveforms with even azimuth coverage of stations.Results reveal that the rupture process of the Lushan MS7.0 event to be simpler than that of the Wenchuan earthquake and also showed significant differences between the two rupture processes.The whole rupture process lasted 36 s and most of the moment was released within the first 13 s.The total released moment is 1.9×1019N m with MW=6.8.Rupture propagated upwards and bilaterally to both sides from the initial point,resulting in a large slip region of 40 km×30 km,with the maximum slip of 1.8 m,located above the initial point.No surface displacement was estimated around the epicenter,but displacement was observed about 20 km NE and SW directions of the epicenter.Both showed slips of less than 40 cm.The rupture suddenly stopped at 20 km NE of the initial point.This was consistent with the aftershock activity.This phenomenon indicates the existence of significant variation of the medium or tectonic structure,which may prevent the propagation of the rupture and aftershock activity.The earthquake risk of the left segment of Qianshan fault is worthy of attention. | ZHAO CuiPing ZHOU LianQing CHEN ZhangLi | 2013 | Chinese Science Bulletin2013,58,28: | 13 |
| 8 | Millennial-scale climate change since the last glaciation recorded by grain sizes of loess deposits on the northeastern Tibetan Plateau显示文摘Whether climatic changes in high latitudes of the Northern Hemisphere since the last glaciation have effects on the Tibetan Plateau monsoon, and the variation characteristics of the Plateau monsoon itself are still not solved but of great significance. The 22-m high-resolution Ioess-paleosol sequence in the Hezuo Basin on the northeastern Tibetan Plateau demonstrates that the Plateau winter monsoon experienced a millennial variation similar to high latitude Northern Hemisphere, with cold events clearly correlated with Heinrich events but less for the warm events (Dansgarrd-Oeschger events). It may indicate that the climate system at high latitudes in the Northern Hemisphere had played an important role in both the Plateau monsoon and the high-level westerlies. On 10^4 year scale, there are two distinct anomalous changes, which are not found in the records from high latitude northern hemisphere, revealed by the loess grain size in the Hezuo Basin. One is that there was a considerable grain size increase at -36 kaBP, suggesting an abrupt enhancement of the Plateau winter monsoon at that time; the other is that, during 43--36 kaBP, the grain size decreased distinctly, indicating a notable weakening of the Plateau winter monsoon around that period. Both of the two anomalies suggest that the Tibetan climate may have been controlled by some other factors, besides the high latitude climatic changes in the Northern Hemisphere. | Lü Lianqing FANG Xiaomin LU Huayu HAN Yongxiang YANG Shengli LI Jijun AN Zhisheng | 2004 | Chinese Science Bulletin2004,49,11: | 13 |

| 10 | Transformation of surface water and groundwater and water balance in the agricultural irrigation area of the Manas River Basin,China显示文摘Calculation of the water balance is very important to relieve the pressure on water resources in arid agricultural irrigation areas.This research focused on irrigation water balance calculations in the Manas River Basin of the southern margin of the Junggar Basin of China,and aimed to analyze the groundwater level dynamic trend and response characteristics of the basin water cycle under water-saving irrigation measures.The surface water and groundwater coupling model of MIKE 11-Visual MODFLOW was used to simulate rainfall runoff in mountainous areas,and quantify the contribution of water balance components in the plain irrigation area.Convergence of the delayed watershed in the mountain area was obvious,and when the river runoff exceeded 200 m^(3)/s,the error in the runoff simulation was large.The water balance in the plain agricultural irrigation area was in a negative equilibrium state,and the difference between recharge and discharge was−2.65 billion m^(3).The evapotranspiration was 24.49 billion m^(3) under drip irrigation,accounting for only approximately 51%of the total discharge.The lateral discharge of the unsaturated and saturated aquifers was 15.38 billion m^(3),accounting for approximately 32%of the total discharge.The main reason for the groundwater decline in the irrigation area was closely related to the extraction of groundwater,because the amount of recharge and discharge in the natural state was approximately identical.The MIKE 11-Visual MODFLOW model produced accurate results,and the research method provided a new exploration technique to quantify the effect of water supply mode on the groundwater table.The model is suitable for the management of water resources in arid areas. | Yang Guang He Xinlin Li Xiaolong Long Aihua Xue Lianqing | 2017 | International Journal of Agricultural and Biological Engineering2017,10,4: | 10 |
| 11 | Research progress in quantifying the mechanical properties of single living cells using atomic force microscopy显示文摘The advent of atomic force microscopy(AFM)provides a powerful tool for investigating the behaviors of single living cells under near physiological conditions.Besides acquiring the images of cellular ultra-microstructures with nanometer resolution,the most remarkable advances are achieved on the use of AFM indenting technique to quantify the mechanical properties of single living cells.By indenting single living cells with AFM tip,we can obtain the mechanical properties of cells and monitor their dynamic changes during the biological processes(e.g.,after the stimulation of drugs).AFM indentation-based mechanical analysis of single cells provides a novel approach to characterize the behaviors of cells from the perspective of biomechanics,considerably complementing the traditional biological experimental methods.Now,AFM indentation technique has been widely used in the life sciences,yielding a large amount of novel information that is meaningful to our understanding of the underlying mechanisms that govern the cellular biological functions.Here,based on the authors’own researches on AFM measurement of cellular mechanical properties,the principle and method of AFM indentation technique was presented,the recent progress of measuring the cellular mechanical properties using AFM was summarized,and the challenges of AFM single-cell nanomechanical analysis were discussed. | Mi Li Lianqing Liu Ning Xi Yuechao Wang | 2014 | Chinese Science Bulletin2014,59,31: | 8 |

| 13 | Developing More Effective Enhanced Biochar Fertilisers for Improvement of Pepper Yield and Quality显示文摘Utilization of biochar at high application rates can increase soil C and crop yields, decrease greenhouse gas emissions and reduce nutrient run-off from soils. However, the high application rate of 10 t ha-1may not return a profit to the farmer due to the high cost of biochar. In this study biochar was modified through pre-treating the biomass and post-treating with phosphoric acid, minerals and different chemical fertilisers to study the effects of two new enhanced biochar fertilisers on the yield and quality of green pepper in a field experiment with 5 fertilisation treatments and 3 replications. The two new biochar fertilisers significantly(P < 0.05) increased the yield of green pepper(11.33–11.47 t ha-1), compared with the conventional chemical fertiliser(9.72 t ha-1). The biochar fertiliser treatments improved the vitamin C content of green pepper from 236.99 to 278.28 mg kg-1, and also significantly(P < 0.05) reduced the nitrate content from 132.32 to 101.92 mg kg-1, compared with chemical fertiliser. This study indicated that, compared to the use of conventional chemical fertiliser, all of the biochar fertiliser treatments could significantly improve the yield and quality of green pepper. | YAO Chunxue Stephen JOSEPH LI Lianqing PAN Genxing Yun LIN Paul MUNROE Ben PACE Sarasadat TAHERYMOOSAVI Lukas VAN ZWIETEN Torsten THOMAS Shaun NIELSEN Jun YE Scott DONNE | 2015 | Pedosphere2015,25,5: | 8 |
| 14 | Development of a pediment on western slopes of Liupan Mountain related to the Neotectonic Uplift显示文摘The late Cenozoic uplift of Qinghai-Xizang Plateau plays an important role in adjacent geomorphic evolution and depositional environments. Liupan Mountain, located at the northeast margin of Qinghai-Xizang Plateau, has different landforms on the east and west sides. Recently, a pediment, which lies above the highest terrace of the Yellow River at the northeast edge of Longzhong Basin, has been described. The paleomagnetic measurements indicate that the pediment had developed at least 1.8 MaBP and its age is in accordance with that of the peneplains near Lanzhou and Linxia, in the southwest of Longzhong Basin. The results suggest that the Longzhong Basin lying to the west of Liupan Mountain had been subject to erosion and developed an extensive pediment; this pediment is named the Gansu Period Peneplain. It also indicates that Qinghai-Xizang Plateau and Liupan Mountain were uplifted strongly at that time, which caused not only the end of pediplanation but also Yellow River appearance and loess | YANG Dong FANG Xiaomin SONG Yougui LU Lianqing LI Jijun | 2001 | Chinese Science Bulletin2001,46,S1: | 7 |
| 15 | Development of micro-and nanorobotics: A review显示文摘Micro-and nanorobotic is an emerging field of research arising from the cross-fusion of micro/nano technology and robotics and has become an important part of robotics.

In addition, from the perspectives of intelligence and sensing, clinical applications, materials and performance, the challenges that may be encountered in the development of such robots in the future are discussed. Finally, the entire article is summarized, and concepts for future micro-and nanorobots are described. | YANG Jia ZHANG Chuang WANG XiaoDong WANG WenXue XI Ning LIU LianQing | 2019 | Science China(Technological Sciences)2019,62,1: | 7 |
| 16 | Progress in measuring biophysical properties of membrane proteins with AFM single-molecule force spectroscopy显示文摘Membrane proteins are crucial in cell physiological activities and are the targets for most drugs.Thus,investigating the behaviors of membrane proteins not only provide deeper insights into cell function,but also help disease treatment and drug development.Atomic force microscopy is a unique tool for investigating the structure of membrane proteins.It can both image the morphology of single native membrane proteins with high resolution and,via single-molecule force spectroscopy(SMFS),directly measure their biophysical properties during molecular physiological activities such as ligand binding and protein unfolding.In the context of molecular biomechanics,SMFS has been successfully used to understand the structure and function of membrane proteins,complementing the static three-dimensional structures of proteins obtained by X-ray crystallography.Here,based on the authors’antigen-antibody binding force measurements in clinical tumor cells,the principle and method of SMFS is discussed,the progress in using SMFS to characterize membrane proteins is summarized,and challenges for SMFS are presented. | Mi Li Lianqing Liu Ning Xi Yuechao Wang | 2014 | Chinese Science Bulletin2014,59,22: | 7 |
| 17 | Atomic force microscopy studies on cellular elastic and viscoelastic properties显示文摘In this work, a method based on atomic force microscopy (AFM) approach-reside-retract experiments was established to simultaneously quantify the elastic and viscoelastic properties of single cells. First, the elastic and viscoelastic properties of normal breast cells and cancerous breast cells were measured, showing significant differences in Young’s modulus and relaxation times between normal and cancerous breast cells. Remarkable differences in cellular topography between normal and cancerous breast cells were also revealed by AFM imaging. Next, the elastic and viscoelasitc properties of three other types of cell lines and primary normal B lymphocytes were measured; results demonstrated the potential of cellular viscoelastic properties in complementing cellular Young’s modulus for discerning different states of cells. This research provides a novel way to quantify the mechanical properties of cells by AFM, which allows investigation of the biomechanical behaviors of single cells from multiple aspects. | Mi Li Lianqing Liu Ning Xi Yuechao Wang | 2018 | Science China(Life Sciences)2018,61,1: | 6 |
| 18 | Mapping CD20 molecules on the lymphoma cell surface using atomic force microscopy显示文摘Atomic force microscopy (AFM) was used to locate CD20 molecules on the surface of lymphoma Raji cells. Rituximab (a monoclonal antibody against CD20) molecules were linked onto the AFM tip via a polyethylene glycol (PEG) linker. Raji cells were adsorbed onto glass slides coated with poly-L-lysine. First, the CD20 distribution in a local area of the cell surface was visualized using the AFM lift scan mode. Second, 16 × 16 force curves were obtained from the same cell area to construct the CD20-rituximab binding force map. Finally, free rituximab was added to block the CD20 molecules on the cell surface and the lift phase image and CD20-rituximab force map were obtained again. The experimental results indicated that when the lift height was greater than the length of the PEG linker, no recognition sites were observed in the lift phase image. However, as the lift height decreased to the length of the PEG linker, some recognition sites were observed in the lift phase image and these sites were generally consistent with the pixels in the force map. After blocking, both the recognition sites in the lift phase image and the gray pixels in the binding force map decreased markedly. These results can improve our understanding of the distribution of protein molecules on the cell surface and facilitate further investigations into cellular functions. | LI Mi LIU LianQing XI Ning WANG YueChao DONG ZaiLi XIAO XiuBin ZHANG WeiJing | 2013 | Chinese Science Bulletin2013,58,13: | 6 |
| 19 | Atomic force microscopy imaging of live mammalian cells显示文摘Atomic force microscopy (AFM) was used to examine the morphology of live mammalian adherent and suspended cells. Time-lapse AFM was used to record the locomotion dynamics of MCF-7 and Neuro-2a cells. When a MCF-7 cell retracted, many small sawtooth-like filopodia formed and reorganized, and the thickness of cellular lamellipodium increased as the retraction progressed. In elongated Neuro-2a cells, the cytoskeleton reorganized from an irregular to a parallel, linear morphology. Suspended mammalian cells were immobilized by method combining polydimethylsiloxane-fabricated wells with poly-L-lysine electrostatic adsorption. In this way, the morphology of a single live lymphoma cell was imaged by AFM. The experimental results can improve our understanding of cell locomotion and may lead to improved immobilization strategies. | LI Mi LIU LianQing XI Ning WANG YueChao DONG ZaiLi XIAO XiuBin ZHANG WeiJing | 2013 | Science China(Life Sciences)2013,56,9: | 6 |
