| 1 | Effects of sulfur fertilization and short-term high temperature on wheat grain production and wheat flour proteins显示文摘The content of wheat flour proteins affects the quality of wheat flour. Sulfur nutrition in wheat can change the protein content of the flour. The inconsistency and instability of wheat grain quality during grain filling under high temperature stress(HTS) are a major challenge to the production of high-quality wheat. The effects of sulfur fertilization and HTS on wheat flour protein and its components are unknown. In this study, treatments varying two factors: sulfur fertilization and exposure to short-term HTS, at 20 days postanthesis, were applied to two wheat cultivars with differing gluten types. Plants of a stronggluten wheat(Gaoyou 2018) and a medium-gluten wheat(Zhongmai 8) were grown in pots in Beijing in 2015–2017. HTS significantly increased the contents of total protein, albumin,gliadin, glutenin, Cys, and Met in wheat kernels, but reduced grain yield, grain weight,protein yield, globulin content, and total starch accumulation. The HTS-induced increase in total protein amount was closely associated with nitrate reductase(NR) and glutamine synthetase(GS) activities in flag leaves. Sulfur fertilization increased grain and protein yields; grain weight; total protein, albumin, gliadin, glutenin, and globulin contents; protein yield; total starch; Cys, Met; and NR and GS activities. HTS and sulfur fertilization had larger effects on the strong-than on the medium-gluten cultivar. Sulfur fertilization also alleviated the negative effects of HTS on grain yield, protein yield, and starch content.Thus, growing wheat with additional soil sulfur can improve the quality of the flour. | Zhiqiang Tao Xuhong Chang Demei Wang Yanjie Wang Shaokang Ma Yushuang Yang Guangcai Zhao | 2018 | The Crop Journal2018，6，4： | 11 |
| 2 | Microstructure, mechanical properties and deformation mechanisms of an as-cast Mg–Zn–Y–Nd–Zr alloy for stent applications显示文摘A new Mg-2Zn-0.2Y -0.5N d-0.4Zr (wt%) alloy designed specially for stent applications has been developed. The as-cast alloy is featured with equiaxed grains with a mean size of about 40 μm and a small am ount of second phase (T phase) distributed discontinuously either at the grain boundaries or inside the grains. This alloy exhibits a tensile elongation of up to 35%, which is much larger than that of most reported other as-cast Mg alloys. The tensile deform ation mechanisms have also been investigated. The results show that, besides basal slip,{10-12} extension twining and non-basal pyramidal slips can also be observed at initial stage and later stage during tensile deform ation, respectively, which are responsible for the good room -tem perature ductility. | Jianfeng Wang Hongbo Zhou Liguo Wang Shijie Zhu Shaokang Guan | 2019 | Journal of Materials Science & Technology2019，35，7： | 9 |
| 3 | Effects of tridimensional uniform sowing on water consumption, nitrogen use, and yield in winter wheat显示文摘Wheat is a staple crop worldwide, but yields may diminish as climate change causes increasingly unpredictable patterns of precipitation and soil nutrient availability. Farmers are thus challenged to maximize planting efficiency to increase yield, while also improving their resource use efficiency. In this study the effectiveness of tridimensional uniform sowing was tested across a range of planting densities for winter wheat crops on the North China Plain. Tridimensional uniform sowing was tested against conventional drilling at three planting densities (180 × 104, 270 × 104, and 360 × 104 plants ha 1) and assessed for water consumption, biomass, nitrogen uptake and allocation, and aspects of yield. The tridimensional uniform sowing treatment outperformed the conventional drilling treatment in most metrics and at most planting densities, while performing markedly better at higher planting densities. Water consumption decreased and nitrogen efficiency increased. Tiller number and percentage of productive tillers, leaf area index, dry weight, and yield increased without a significant decline in grain protein. Nitrogen allocation was more efficient under tridimensional uniform sowing than with conventional drilling, and also varied according to annual precipitation and planting density. Both yield and grain protein contents were significantly correlated with the amount of pre-anthesis accumu- lated nitrogen translocated from vegetative organs to kernels after anthesis. Overall, a density of 270 × 104 plants ha 1 provided the highest water use efficiency and grain yield. Tridimensional uniform sowing will benefit farmers by forming stronger overall crops, promoting the coordinated improvement of yield, nitrogen uptake and efficiency, and increasing grain protein content at higher planting densities. | Zhiqiang Tao Shaokang Ma Xuhong Chang Demei Wang Yanjie Wang Yushuang Yang Guangcai Zhao Jiancang Yang | 2019 | The Crop Journal2019，7，4： | 8 |
| 4 | Multifunctional MgF_2/Polydopamine Coating on Mg Alloy for Vascular Stent Application显示文摘Mg alloy is of great potential in the application of vascular stent due to its degradation in physical environment and proper mechanical property.However its mechanical integrity does not meet the clinical requirement due to relatively fast degradation.Besides,in order to accelerate the reendothelialization of Mg-based stents,it needs surface modification to improve the attachment,growth and adhesion of endothelial cells(ECs).To solve the main obstacles,an anti-corrosion and quick endothelialization coating was prepared on novel Mg-Zn-Y-Nd alloy via a simple two-step immersion method in the present study,first in hydrofluoric acid(HF) then in dopamine tris-Hydrochloric acid(tris-HC1) solution.The coating was uniform and thin,which consisted of two layers—the upper was polydopamine(PDA) layer and the lower was MgF_2 layer.The alloy with the coating demonstrated dramatic corrosion resistance enhancement in vitro by immersion test and electrochemical test.Moreover the HFPDA-treated Mg alloy exhibited great performance of cell adhesion and proliferation.The coating created a favorable environment for ECs to have a competitive advantage over vascular smooth muscle cells(VSMCs),which was preferable for re-endothelialization.The results suggest that HF-PDA-treated Mg-Zn-Y-Nd alloy has great potential in the application of vascular stent and the surface coating method is of great application value in biodegradable Mg alloy stent due to its simplicity and effectiveness. | Xiaoli Liu Zhen Zhen Jing Liu Tingfei Xi Yudong Zheng Shaokang Guan Yufeng Zheng Yan Cheng | 2015 | Journal of Materials Science & Technology2015，31，7： | 8 |
| 5 | Real-time prediction of rock mass classification based on TBM operation big data and stacking technique of ensemble learning显示文摘Real-time prediction of the rock mass class in front of the tunnel face is essential for the adaptive adjustment of tunnel boring machines(TBMs).During the TBM tunnelling process,a large number of operation data are generated,reflecting the interaction between the TBM system and surrounding rock,and these data can be used to evaluate the rock mass quality.This study proposed a stacking ensemble classifier for the real-time prediction of the rock mass classification using TBM operation data.Based on the Songhua River water conveyance project,a total of 7538 TBM tunnelling cycles and the corresponding rock mass classes are obtained after data preprocessing.Then,through the tree-based feature selection method,10 key TBM operation parameters are selected,and the mean values of the 10 selected features in the stable phase after removing outliers are calculated as the inputs of classifiers.The preprocessed data are randomly divided into the training set(90%)and test set(10%)using simple random sampling.Besides stacking ensemble classifier,seven individual classifiers are established as the comparison.These classifiers include support vector machine(SVM),k-nearest neighbors(KNN),random forest(RF),gradient boosting decision tree(GBDT),decision tree(DT),logistic regression(LR)and multilayer perceptron(MLP),where the hyper-parameters of each classifier are optimised using the grid search method.The prediction results show that the stacking ensemble classifier has a better performance than individual classifiers,and it shows a more powerful learning and generalisation ability for small and imbalanced samples.Additionally,a relative balance training set is obtained by the synthetic minority oversampling technique(SMOTE),and the influence of sample imbalance on the prediction performance is discussed. | Shaokang Hou Yaoru Liu Qiang Yang | 2022 | Journal of Rock Mechanics and Geotechnical Engineering2022，14，1： | 8 |
| 6 | Fabrication and characterization of biodegradable Mg-Zn-Y-Nd-Ag alloy:Microstructure,mechanical properties,corrosion behavior and antibacterial activities显示文摘Magnesium(Mg),a potential biodegradable material,has drawn wide attention in the bone reconstruction field.However,Mg alloys,served as the bone graft substitution,remain a clinical challenge,the antibacterial activity of which is required to be enhanced.Here,we prepared biodegradable magnesium Mg-Zn-Y-Nd-Ag and then had it been further densified by extruding.The microstructure evolution of the as-cast and as-extruded Mg-Zn-Y-Nd-Ag was characterized using optical microscope and X-ray diffraction analyses(XRD).The results showed that the microstructure of the as-cast alloys was mainly dendrites,between which,the second phase was mainly distributed;with the increase of Ag additions,grain structure was further refined as well as the increase of amount of the second phase.After the extrusion,the grains were further refined.Microhardness tests indicated that both of the increase of Ag content and the extrusion process improved the microhardness of the alloys,specially the later.A systematic investigation of the in vivo antibacterial capability of Staphylococcus aurous and Escherichia coli was performed,and the results of which indicated that all Mg-Zn-Y-N-xAg(x?0.2,0.4,0.6,0.8)alloys exhibited certain antibacterial property,which would increased with the increase of Ag content.Taken all together,the antimicrobial property of the as-extruded alloy containing 0.4 wt%Ag exhibited the relatively better antimicrobial properties and mechanical property with the relatively small loss in corrosion resistance,which suggested the potential utility of as-extruded Mg-Zn-Y-N-0.4Ag in treating orthopedic infections. | Yashan Feng Shijie Zhu Liguo Wang Lei Chang Yachen Hou Shaokang Guan | 2018 | Bioactive Materials2018，3，3： | 7 |
| 7 | Investigation of Mg–Zn–Y–Nd alloy for potential application of biodegradable esophageal stent material显示文摘In recent years,due to unhealthy dietary habits and other reasons,advanced esophageal cancer patients are on the rise,threatening human health and life safety at all times.Stents implantation as an important complementary or alternative method for chemotherapy has been widely applied in clinics.However,the adhesion and proliferation of pathological cells,such as tumor cells,fibroblasts and epithelial cells,may interfere the efficacy of stents.Further multiple implantation due to restenosis may also bring pain to patients.In this contribution,we preferred a biodegradable material Mg–Zn–Y–Nd alloy for potential application of esophageal stent.The hardness testing showed that Mg–Zn–Y–Nd alloy owned less mechanical properties compared with the commercial esophageal stents material,317L stainless steel(317L SS),while Mg–Zn–Y–Nd displayed significantly better biodegradation than 317L SS.Cell apoptosis assay indicated Mg–Zn–Y–Nd inhibited adhesion and proliferation of tumor cells,fibroblasts and epithelial cells.Our research suggested potential application of Mg–Zn–Y–Nd alloy as a novel material for biodegradable esophageal stent. | Shuo Wang Xueqi Zhang Jingan Li Changsheng Liu Shaokang Guan | 2020 | Bioactive Materials2020，5，1： | 7 |
| 8 | Mg-Zn-Y-Nd coated with citric acid and dopamine by layer-by-layer self-assembly to improve surface biocompatibility显示文摘Magnesium alloy has been generally accepted as an important biodegradable material on cardiovascular stent development for a long time. However, its limited biocompatibility, especially delayed endothelialization process restricts its further application. In this contribution, we modified the Mg-Zn-Y-Nd alloy surface with citric acid and dopamine via a layer-by-layer self-assembly assay, aiming at improving the biocompatibility of the magnesium alloy. The citric acid/dopamine(CA/PDA) layer exhibited a remarkable suppression of platelet activation/aggregation and thrombosis under 15 dyn/cm2 blood flowing. Inhibition on vascular smooth muscle cells growth and macrophages attachment/activation were also observed on this layer. In particular, the CA/PDA layer presented a promoted property for the vascular endothelial cells growth and spreading compared with the bare magnesium alloy, suggesting the pro-endotelialized function. In conclusion, this research may support potential application on surface modification of magnesium alloy based cardiovascular stents for better biocompatibility. | CHEN Li LI JingAn CHANG JiaWei JIN ShiBo WU Di YAN HaoHao WANG XiaoFeng GUAN ShaoKang | 2018 | Science China(Technological Sciences)2018，61，8： | 7 |
| 9 | Influence of luteolin on the apoptosis of esophageal cancer Eca109 cells and its mechanism of action显示文摘The present study was conducted to verify the influence of luteolin on apoptosis of Eca109 cells and to further investigate the possible mechanisms underlying its effect on apoptosis.The cells were exposed to different concentrations of luteolin(0,40,80,120,160,200,240M)for 24,48,and 72 h respectively.The influence of luteolin on proliferation of Eca109 cells was detected using MTT assay.Eca109 cells were then treated with luteolin(0,40,160,240M)for 24 h.The effect of luteolin on cell cycle progression and apoptosis was assayed by using flow cytometry(FCM).Expression of caspase9 and caspase3 mRNA and protein was analyzed by real-time PCR and Western blot respectively.The results showed that luteolin could inhibit the proliferation of Eca109 cells at all concentrations in a time-dependent manner and the relative inhibition rate showed an inverted U-shaped association with the concentration of luteolin.Further,the cell cycle was arrested in the S phase following treatment with luteolin.Apoptosis analysis indicated that luteolin could induce the apoptosis of Eca109 cells across the three concentration groups,which exhibited a trend of first promotional and then inhibitory with the increases in luteolin concentration.The effect of luteolin on the mRNA and protein expression of caspase 9 and caspase3 first manifested as promotion,then inhibition.Therefore,luteolin may serve a role in promoting cell apoptosis by inducing Eca109 cell apoptosis that involves the expression of caspase3,caspase9 mRNA and protein.This study provides theoretical basis for further study and clinical application of luteolin.The specific mechanism has not yet been clarified and the other activation pathways inducing apoptosis need to be further studied. | Shaokang Wang Lingmeng Fu Yi Wu Hongmei Xiao Jing Wang Guiju Sun | 2019 | Food Science and Human Wellness2019，8，2： | 6 |

| 11 | Characterization and corrosion property of nano-rod-like HA on fluoride coating supported on Mg-Zn-Ca alloy×显示文摘The poor corrosion resistance of biodegradable magnesium alloys is the dominant factor that limits theirclinical application. In this study, to deal with this challenge, fluoride coating was prepared on MgeZneCa alloy as the inner coating and then hydroxyapatite (HA) coating as the outer coating was depositedon fluoride coating by pulse reverse current electrodeposition (PRC-HA/MgF2). As a comparative study,the microstructure and corrosion properties of the composite coating with the outer coating fabricatedby traditional constant current electrodeposition (TED-HA/MgF2) were also investigated. Scanningelectron microscopy (SEM) images of the coatings show that the morphology of PRC-HA/MgF2 coating isdense and uniform, and presents nano-rod-like structure. Compared with that of TED-HA/MgF2, thecorrosion current density of Mg alloy coated with PRC-HA/MgF2 coatings decreases from 5.72× 10^-5 A/cm2 to 4.32× 10^-7 A/cm^2, and the corrosion resistance increases by almost two orders of magnitude. Inimmersion tests, samples coated with PRC-HA/MgF2 coating always show the lowest hydrogen evolutionamount, and could induce deposition of the hexagonal structure-apatite on the surface rapidly. Theresults show that the corrosion resistance and the bioactivity of the coatings have been improved byadopting double-pulse current mode in the process of preparing HA on fluoride coating, and the PRC-HA/MgF2 coating is worth of further investigation. | Yashan Feng Shijie Zhu Liguo Wang Lei Chang Bingbing Yan Xiaozhe Song Shaokang Guan | 2017 | Bioactive Materials2017，2，2： | 6 |
| 12 | Spontaneous firing in olfactory bulb neurons of Bufo bufo gargarizans in and after hibernation显示文摘Microelectrode technique was used to record the spontaneous electrical activities of the neurons in olfactory bulb of the Bufo bufo gargarizans, both in hibernation and after hibernation. This study investigated the electrophysiological characteristics of amphibian olfactory bulb in the period of hibernation and after hibernation and its effects on the start of hibernation and spontaneous awakening. The research showed four forms of spontaneous firings: single spontaneous firing, burst spontaneous firing, irregular spontaneous firing and consecutive single spontaneous firing. The single spontaneous firing includes slow depolarized spontaneous firing and fast depolarized spontaneous firing, and the slow depolarized spontaneous firing occurs only during the hibernation period. In hibernation, the low amplitude and low frequency firing with a longer duration may be relevant to maintaining the tonicity of the central nervous system in toads that are in hibernation, and this kind of firing may also provide an excited basis for their arousal from hibernation. After hibernation, the amplitude and frequency of firing increase, but the firing duration gets shorter. This form of short-term firing, which may be a phenomenon of sensory neurons fast adapting, is one of the neuronal mechanisms for the arousal of hibernating animals. | Chuancheng Liang Shaokang Bian Xia Peng Liwen Wang | 2011 | Neural Regeneration Research2011，6，11： | 4 |
| 13 | Biocompatibility of nano-hydroxyapatite/Mg-Zn-Ca alloy composite scaffolds to human umbilical cord mesenchymal stem cells from Wharton's jelly in vitro显示文摘Seeding cells and scaffolds play pivotal roles in bone tissue engineering and regenerative medicine.Wharton’s jelly-derived mesenchymal stem cells(WJCs)from human umbilical cord represent attractive and promising seeding cells in tissue regeneration and engineering for treatment applications.This study was carried out to explore the biocompatibility of scaffolds to seeding cells in vitro.Rod-like nano-hydroxyapatite(RN-HA)and flake-like micro-hydroxyapatite(FM-HA)coatings were prepared on Mg-Zn-Ca alloy substrates using micro-arc oxidation and electrochemical deposition.WJCs were utilized to investigate the cellular biocompatibility of Mg-Zn-Ca alloys after different surface modifications by observing the cell adhesion,morphology,proliferation,and osteoblastic differentiation.The in vitro results indicated that the RN-HA coating group was more suitable for cell proliferation and cell osteoblastic differentiation than the FM-HA group,demonstrating better biocompatibility.Our results suggested that the RN-HA coating on Mg-Zn-Ca alloy substrates might be of great potential in bone tissue engineering. | GUAN FangXia MA ShanShan SHI XinYi MA Xun CHI LianKai LIANG Shuo CUI YuanBo WANG ZhiBin YAO Ning GUAN ShaoKang YANG Bo | 2014 | Science China(Life Sciences)2014，57，2： | 4 |
| 14 | Single-Step Organization of Plasmonic Gold Metamaterials with Self-Assembled DNA Nanostructures显示文摘Self-assembled DNA nanostructures hold great promise as nanoscale templates for organizing nanoparticles(NPs)with nearatomistic resolution.However,large-scale organization of NPs with high yield is highly desirable for nanoelectronics and nanophotonic applications.Here,we design fve-strand DNA tiles that can readily self-assemble into well-organized micrometerscale DNA nanostructures.By organizing gold nanoparticles(AuNPs)on these self-assembled DNA nanostructures,we realize the fabrication of one-and two-dimensional Au nanostructures in single steps.We further demonstrate the one-pot synthesis of Au metamaterials for highly amplifed surface-enhanced Raman Scattering(SERS).Tis single-step and high-yield strategy thus holds great potential for fabricating plasmonic metamaterials. | Shaokang Ren Jun Wang Chunyuan Song Qian Li Yanjun Yang Nan Teng Shao Su Dan Zhu Wei Huang Jie Chao Lianhui Wang Chunhai Fan | 2019 | Research2019，，1： | 4 |
| 15 | Microstructure and texture evolution of fine-grained Mg-Zn-Y-Nd alloy micro-tubes for biodegradable vascular stents processed by hot extrusion and rapid cooling显示文摘Magnesium alloys have narrow available slip result from close-packed hexagonal structure that limit their processing properties.In the recent work,the Mg-2Zn-0.46Y-0.5Nd,as materials for degradable stents,was applied to produce as-extruded micro-tube with an outer diameter of 3.0mm and a wall thickness of 0.35mm by hot extrusion with an extrusion ratio of 105:1 at 653K and rapid cooling.The fine microstructure of the dynamic recrystallization of as-extruded micro-tube could be preserved by rapid cooling such as water-cooled,resulting in more excellent mechanical properties relative to air-cooled micro-tube.The addition of rare earth elements Y and Nd results in continuous dynamic recrystallization dominated the dynamic recrystallization mechanism.During the hot extrusion process,the activation of the non-basal slip system,especially the pyramidal(c+a)slip,could significantly weaken the texture strength,and the as-extruded micro-tube exhibits weak'RE'texture components(011^(-)1)||ED and(1^(-)21^(-)1)||ED.Hence,the magnesium alloy micro-tube prepared by the rapid cooling has fine microstructure and weak texture,which is favorable for further process and governance. | Kaikai Guo Mengyao Liu Jianfeng Wang Yufeng Sun Weiqing Li Shijie Zhu Liguo Wang Shaokang Guan | 2020 | Journal of Magnesium and Alloys2020，8，3： | 3 |
| 16 | Synthesis and properties of a Pr(III) complex with 2-acetyl- benzimidazoledehyde-glycine Schiff-base ligand显示文摘The 2-acetyl-benzimidazoledehyde-gly- cine Schiff-base ligand and the corresponding Pr(III) complex Pr2L3(NO3)3·2CH3OH (L=C11H10N3O2) were synthesized in methanol and characterized by a series of methods, including chemical analysis, elemental analysis, TOF-MS, 1H NMR, UV-, IR-, Raman spectra, thermal analysis, and the three-dimension fluores- cence excitation and emission spectra. The Pr(III) complex exhibits extraordinary water-solubility and the Pr(III) hydroxide appears at pH≥13. The complex also possesses specific fluorescent properties.

| 17 | Improved mechanical, degradation, and biological performances of Zn–Fe alloys as bioresorbable implants显示文摘Zinc(Zn)is a promising bioresorbable implant material with more moderate degradation rate compared to magnesium(Mg)and iron(Fe).However,the low mechanical strength and localized degradation behavior of pure Zn limit its clinical applications.Alloying is one of the most effective ways to overcome these limitations.After screening the alloying element candidates regarding their potentials for improvement on the degradation and biocompatibility,we proposed Fe as the alloying element for Zn,and investigated the in vitro and in vivo performances of these alloys in both subcutaneous and femoral tissues.Results showed that the uniformly distributed secondary phase in Zn–Fe alloys significantly improved the mechanical property and facilitated uniform degradation,which thus enhanced their biocompatibility,especially the Zn-0.4Fe alloy.Moreover,these Zn–Fe alloys showed outstanding antibacterial property.Taken together,Zn–Fe alloys could be promising can-didates as bioresorbable medical implants for various cardiovascular,wound closure,and orthopedic applications. | Yingchao Su Jiayin Fu Wonsae Lee Shaokang Du Yi-Xian Qin Yufeng Zheng Yadong Wang Donghui Zhu | 2022 | Bioactive Materials2022，7，11： | 3 |

| 19 | A two-step superplastic forging forming of semi-continuously cast AZ70 magnesium alloy显示文摘A two-step technology combined forging with superplastic forming has been developed to enhance the forgeability of semi-continuously cast AZ70 magnesium alloy and realize the application of the as-cast magnesium alloy in large deformation bullet shell.In the first step,fine-grained microstructure preforms that are suitable for superplastic forming were obtained by reasonably designing the size of the initial blanks with the specific height-to-diameter ratio,upsetting the blanks and subsequent annealing.In the second step,the heat treated preforms were forged into the end products at the superplastic conditions.The end products exhibit high quality surface and satisfied microstructure.Consequently,this forming technology that not only avoids complicating the material preparation but also utilizes higher strain rate superplastic provides a near net-shaped novel method on magnesium forging forming technology using as-cast billet. | Pan Wang Shijie Zhu Liguo Wang Lihong Wu Shaokang Guan | 2015 | Journal of Magnesium and Alloys2015，3，1： | 2 |
| 20 | Effect of rare earth and Mn elements on the corrosion behavior of extruded AZ61 system in 3.5 wt%NaCl solution and salt spray test显示文摘In this study,multiple addition of rare earth(RE)and manganese(Mn)to AZ61 was conducted aiming to find out the influence to corrosion resistance.AZ61 containing different amounts of RE and Mn was investigated by electrochemical measurement in condition of 3.5 wt%NaCl solution at 25°C.Gravimetric measurement was conducted in 5 wt%salt spray at 35°C and 3.5 wt%NaCl solution at 25°C.Samples were characterized by SEM,EDS,OM and XRD.The result shows that with RE addition Al8Mn5 in AZ61 changed into Al10RE2Mn7.The quantity ofβphase is reduced significantly.The multiple addition of RE and Mn improved the corrosion resistance of AZ61.When the ratio of Mn and RE is 0.3,alloy has the best property of corrosion resistance.In addition,the composite addition removed the impurity elements in AZ61 especially Fe. | Shijie Zhu Zhidan Liu RuiXiao Qu LiGuo Wang Qingkui Li Shaokang Guan | 2013 | Journal of Magnesium and Alloys2013，1，3： | 2 |
