| 1 | Annual cost of illness of stomach and esophageal cancer patientsin urban and rural areas in China: A multi-center study显示文摘Objective: Stomach and esophageal cancer are imposing huge threats to the health of Chinese people whereas there were few studies on the financial burden of the two cancers.Methods: Costs per hospitalization of all patients with stomach or esophageal cancer discharged between September 2015 and August 2016 in seven cities/counties in China were collected, together with their demographic information and clinical details. Former patients in the same hospitals were sampled to collect information on annual direct non-medical cost, indirect costs and annual number of hospitalization. Annual direct medical cost was obtained by multiplying cost per hospitalization by annual number of hospitalization. Annual cost of illness(ACI)was obtained by adding the average value of annual direct medical cost, direct non-medical cost and indirect cost,stratified by sex, age, clinical stage, therapy and pathologic type in urban and rural areas. Costs per hospitalization were itemized into eight parts to calculate the proportion of each part. All costs were converted to 2016 US dollars(1 USD=6.6423 RMB).Results: Totally 19,986 cases were included, predominately male. Mean ages of stomach cancer and urban patients were lower than that of esophageal cancer and rural patients. ACI of stomach and esophageal cancer patients were $10,449 and $13,029 in urban areas, and $2,927 and $3,504 in rural areas, respectively. Greater ACI was associated with male, non-elderly patients as well as those who were in stage I and underwent surgeries.Western medicine fee took the largest proportion of cost per hospitalization.Conclusions: The ACI of stomach and esophageal cancer was tremendous and varied substantially among the population in China. Preferential policies of medical insurance should be designed to tackle with this burden and further reduce the health care inequalities. | Zhixun Yang Hongmei Zeng Ruyi Xia Qian Liu Kexin Sun Rongshou Zheng Siwei Zhang Changfa Xia He Li Shuzheng Liu Zhiyi Zhang Yuqin Liu Guizhou Guo Guohui Song Yigong Zhu Xianghong Wu Bingbing Song Xianzhen Liao Yanfang Chen Wenqiang Wei Guihua Zhuang Wanqing Chen | 2018 | Chinese Journal of Cancer Research2018,30,4: | 22 |
| 2 | A hybrid invisibility cloak based on integration of transparent metasurfaces and zero-index materials显示文摘The invisibility cloak,a long-standing fantastic dream for humans,has become more tangible with the development of metamaterials.Recently,metasurface-based invisibility cloaks have been proposed and realized with significantly reduced thickness and complexity of the cloaking shell.However,the previous scheme is based on reflection-type metasurfaces and is thus limited to reflection geometry.In this work,by integrating the wavefront tailoring functionality of transparent metasurfaces and the wave tunneling functionality of zero-index materials,we have realized a unique type of hybrid invisibility cloak that functions in transmission geometry.The principle is general and applicable to arbitrary shapes.For experimental demonstration,we constructed a rhombic double-layer cloaking shell composed of a highly transparent metasurface and a double-zero medium consisting of dielectric photonic crystals with Dirac cone dispersions.The cloaking effect is verified by both full-wave simulations and microwave experimental results.The principle also reveals exciting possibilities for realizing skin-thick ultrathin cloaking shells in transmission geometry,which can eliminate the need for spatially varying extreme parameters.Our work paves a path for novel optical and electromagnetic devices based on the integration of metasurfaces and metamaterials. | Hongchen Chu Qi Li Bingbing Liu Jie Luo Shulin Sun Zhi Hong Hang Lei Zhou Yun Lai | 2018 | Light(Science & Applications)2018,7,1: | 13 |
| 3 | Roles of a sustained activation of NCED3 and the synergistic regulation of ABA biosynthesis and catabolism in ABA signal production in Arabidopsis显示文摘ABA, acting as a stress signal, plays crucial roles in plant resistance to water stress. Because ABA signal production is based on ABA biosynthesis, the regulation of NCED, a key enzyme in the ABA biosynthesis pathway, is normally thought of as the sole factor controlling ABA signal production. Here we demonstrate that ABA catabolism in combination with a synergistic regulation of ABA biosynthesis plays a crucial role in governing ABA signal production. Water stress induced a significant accumulation of ABA, which exhibited different patterns in detached and attached leaves. ABA catabolism followed a temporal trend of exponential decay for both basic and stress ABA, and there was little difference in the catabolic half-lives of basic ABA and stress ABA. Thus, the absolute rate of ABA catabolism, i.e. the amount of ABA catabolized per unit time, increases with increased ABA accumulation. From the dynamic processes of ABA biosynthesis and catabolism, it can be inferred that stress ABA accumulation may be governed by a synergistic regulation of all the steps in the ABA biosynthesis pathway. Moreover, to maintain an elevated level of stress ABA sustained activation of NCED3 should be required. This inference was supported by further findings that the genes encoding major enzymes in the ABA biosynthesis pathway, e.g. NCED3, AAO3 and ABA3 were all activated by water stress, and with ABA accumulation progressing, the expressions of NCED3, AAO3 and ABA3 remained activated. Data on ABA catabolism and gene expression jointly indicate that ABA signal production is controlled by a sustained activation of NCED3 and the synergistic regulation of ABA biosynthesis and catabolism. | REN HuiBo FAN YiJian GAO ZhiHui WEI KaiFa LI GuiFen LIU Jing CHEN Lin LI BingBing HU JianFang JIA WenSuo | 2007 | Chinese Science Bulletin2007,52,4: | 12 |
| 4 | Antidepressant effect of Xingnao Jieyu decoction mediated by alleviating neuroinflammation in a rat model of post-stroke depression显示文摘OBJECTIVE: To identify the antidepressant effect of Xingnao Jieyu (XNJY) decoction on a post-stroke depression (PSD) rat model and the underlying molecular mechanism. METHODS: We established a rat PSD model by middle cerebral artery occlusion (MCAO) combined with chronic unpredictable mild stress (CUMS). Healthy SD rats were randomly divided into six groups: sham, PSD, fluoxetine (Flu), and XNJY groups at low, middle, and high doses. The sham group underwent sham operation, while the other groups underwent MCAO+CUMS. The Flu and XNJY decoction groups were intragastrically administered with Flu or different doses of XNJY for 21 consecutive days. Histopathological changes in the cortex and hippocampus were observed by staining with hematoxylin and eosin and Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling. Iba1 positive cells were evaluated by immunofluorescence assay. The expressions of tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), interleukin-1β(IL-1β), 5-hydroxytryptamine (5-HT), and norepinephrine (NE) in the cortex and hippocampus were measured by enzyme linked immunosorbent assay. RESULTS: The PSD group rats had a significant decrease in body weight, consumption of sucrose water, and locomotor activity but an increase in immobility time during a forced swimming test (P < 0.01) compared with sham group. Flu and different doses of XNJY significantly recovered these indices (P < 0.01). XNJY also inhibited neuronal damage and apoptosis in the cortex induced by PSD (P < 0.01). Furthermore, XNJY reduced the number of Iba1 positive cells and the expressions of TNF-α, IL-6, and IL-1β, in addition to recovered the levels of 5-HT and NE in the cortex and hippocampus (P < 0.01). CONCLUSION: The alleviation of neuroinflammation might be an important mechanism of the XNJY decoction against PSD. Thus, XNJY might be a promising candidate for the treatment of PSD. | Yan Yongmei Li Tao Wang Dou Zhao Bingbing Zhou Qi | 2019 | Journal of Traditional Chinese Medicine2019,39,5: | 11 |
| 5 | Integrated energy-oriented cruising control of electric vehicle on highway with varying slopes considering battery aging显示文摘Eco-driving strategies for vehicles with conventional powertrains have been studied for years and attempt to reduce fuel consumption by optimizing the driving velocity profile.For electric vehicles(EVs)with regenerative braking,the speed profile with the best energy efficiency should be different from conventional vehicles.This paper proposes an energy-oriented cruising control strategy for EVs with a hierarchical structure to realize eco-cruising on highways with varying slopes.The upper layer plans the energy-optimized vehicle velocity,and the lower layer calculates the torque allocation between the front and rear axles.However,the resulting speed profile with varying velocity may cause a high charge and discharge rate of the battery,resulting in rapid battery fading.To extend the battery life,we make a tradeoff between the energy consumption and wear of the battery by formulating an optimal control problem,where driving comfort and travel time are also considered.An indirect optimal control method is implemented to derive the optimal control rule.As an extension,the control rule for avoiding rear-end collisions is presented and simulated for driving in the real world. | ZHUANG WeiChao QU LingHu XU ShaoBing LI BingBing CHEN Nan YIN GuoDong | 2020 | Science China(Technological Sciences)2020,63,1: | 10 |
| 6 | Gene expression profiling of rat livers with Yin-deficiency-heat syndrome显示文摘OBJECTIVE: To explore the nature of 'Yin internal heat caused byYin-deficiency,' in terms of the theory of Traditional Chinese Medicine, by studying energy metabolism in rats with Yin-deficiency-heat syndrome and analyzing the gene expression profile of their livers. METHODS: A Yin-deficiency-heat syndrome model was induced in rats using three Chinese medicinal herbs. Glycogen and triglycerides in blood plasma, and the enzyme activity of ATP in livers were measured colorimetrically. Triiodothyronine (T3 ), thyroxine (T4 ), and thyroid stimulating hormone levels in blood plasma were also measured with enzyme linked immunosorbent assay. The gene expression profile of livers was detected with gene chip analysis. Differentially expressed genes were screened out and classified according to Gene Ontology. The accuracy of results were examined with reversetranscription-polymerase chain reaction. RESULTS: Compared with the control group, body weight (P<0.05) and hepatic glycogen (P<0.05) were significantly lower in the Yin-deficiency-heat syndrome group. Moreover, toe temperature (P< 0.01) and triglyceride (P<0.05), Na+ -K+ -ATPase (P< 0.01), Mg2+ -ATPase (P<0.01), T3 (P<0.05), and T4 (P< 0.01) levels were significantly higher. There were 99 differentially expressed genes in livers from the Yin-deficiency-heat syndrome group. Genes were mainly related to sterol synthesis (Pc=0.0392), defense response (Pc=0.0448), and sterol metabolism (Pc=0.0533). CONCLUSION: Abnormal expression genes in rats with Yin-deficiency-heat syndrome prompted the synthesis and metabolism of cholesterol, increased energy consumption, and reduced defense response. This gene expression might be the molecular mechanism underlying 'internal heat caused by Yin-deficiency' in the rats with Yin-deficiency-heat syndrome. | Bingbing Han Shijun Wang Lin Li YuanWang Haijun Zhao | 2013 | Journal of Traditional Chinese Medicine2013,33,3: | 8 |
| 7 | Medical expenditures for colorectal cancer diagnosis and treatment: A 10-year high-level-hospital-based multicenter retrospective survey in China, 2002-2011显示文摘Objective: Colorectal cancer(CRC) causes a substantial burden of disease in China and the evidence of economic burden triggered is fundamental for priority setting. The aim of this survey was to quantify medical expenditures and the time trends for CRC diagnosis and treatment in China.Methods: From 2012 to 2014, a hospital-based multicenter retrospective survey was conducted in 13 provinces across China. For each eligible CRC patient diagnosed from 2002 to 2011, clinical information and expenditure data were extracted using a uniform questionnaire. All expenditure data were reported in Chinese Yuan(CNY)using 2011 values.Results: Of the 14,536 CRC patients included, the average age at diagnosis was 58.2 years and 15.8% were stageI cases. The average medical expenditure per patient was estimated at 37,902 CNY [95 % confidence interval(95%CI): 37,282-38,522], and the annual average increase rate was 9.2% from 2002 to 2011(P for trend <0.001), with a cumulative increase of 2.4 times(from 23,275 CNY to 56,010 CNY). The expenditure per patient in stages Ⅰ, Ⅱ, Ⅲ and Ⅳ were 31,698 CNY, 37,067 CNY, 38,918 CNY and 42,614 CNY, respectively(P<0.001). Expenditure significantly differed within various subgroups. Expenses for drugs contributed the largest proportion(52.6%).Conclusions: These conservative estimates illustrated that medical expenditures for CRC diagnosis and treatment in tertiary hospitals in China were substantial and increased rapidly over the 10 years, with drugs continually being the main expense by 2011. Relatively, medical expenditures are lower for CRC in the earlier stages. These findings will facilitate the economic evaluation of CRC prevention and control in China. | Jufang Shi Guoxiang Liu Hong Wang Ayan Mao Chengcheng Liu Lanwei Guo Huiyao Huang Jiansong Ren Xianzhen Liao Yana Bai Xiaojie Sun Xinyu Zhu Jialin Wang Bingbing Song Jinyi Zhou Lin Zhu Haike Lei Yuqin Liu Yunyong Liu Lingbin Du Yutong He Kai Zhang Ni Li Wanqing Chen Min Dai Jie He | 2019 | Chinese Journal of Cancer Research2019,31,5: | 8 |

| 9 | Genomic insights into the fast growth of paulownias and the formation of Paulownia witches' broom显示文摘Paulownias are among the fastest growing trees in the world,but they often suffer tremendous loss of wood production due to infection by Paulownia witches'broom(PaWB)phytoplasmas.In this study,we have sequenced and assembled a high-quality nuclear genome of Paulownia fortunei,a commonly cultivated paulownia species.The assembled genome of P.fortunei is 511.6 Mb in size,with 93.2%of its sequences anchored to 20 pseudo-chromosomes,and it contains 31985 protein-coding genes.Phylogenomic analyses show that the family Paulowniaceae is sister to a clade composed of Phrymaceae and Orobanchaceae.Higher photosynthetic efficiency is achieved by integrating C3 photosynthesis and the crassulacean acid metabolism pathway,which may contribute to the extremely fast growth habit of paulownia trees.Comparative transcriptome analyses reveal modules related to cambial growth and development,photosynthesis,and defense responses.Additional genome sequencing of PaWB phytoplasma,combined with functional analyses,indicates that the effector PaWB-SAP54 interacts directly with Paulownia PfSPLa,which in turn causes the degradation of PfSPLa by the ubiquitin-mediated pathway and leads to the formation of witches'broom.Taken together,these results provide significant insights into the biology of paulownias and the regulatory mechanism for the formation of PaWB. | Yabing Cao Guiling Sun Xiaoqiao Zhai Pingluo Xu Liming Ma Minjie Deng Zhenli Zhao Haibo Yang Yanpeng Dong Zhonghai Shang Yujie Lv Lijun Yan Haifang Liu Xibing Cao Bingbing Li Zhe Wang Xiaogai Zhao Haiyan Yu Fan Wang Wen Ma Jinling Huang Guoqiang Fan | 2021 | Molecular Plant2021,14,10: | 7 |

| 11 | A Tailored High-Efficiency Sample Pretreatment Method for Simultaneous Quantification of 10 Classes of Known Endogenous Phytohormones显示文摘One of the hottest topics in plant hormone biology is the crosstalk mechanisms,whereby multiple classes of phytohormones interplay with each other through signaling networks.To better understand the roles of hormonal crosstalks in their complex regulatory networks,it is of high significance to investigate the spatial and temporal distributions of multiple-phytohormones simultaneously from one plant tissue sample.In this study,we develop a high-sensitivity and high-throughput method for the simultaneous quantitative analysis of 44 phytohormone compounds,covering currently known 10 major classes of phytohormones(strigolactones,brassinosteroids,gibberellins,auxin,abscisic acid,jasmonic acid,salicylic acid,cytokinins,ethylene,and polypeptide hormones[e.g.,phytosulfokine])from only 100 mg of plant sample.These compounds were grouped and purified separately with a tailored solid-phase extraction procedure based on their physicochemical properties and then analyzed by LC–MS/MS.The recoveries of our method ranged from 49.6%to 99.9%and the matrix effects from 61.8%to 102.5%,indicating that the overall sample pretreatment design resulted in good purification.The limits of quantitation(LOQs)of our method ranged from 0.06 to 1.29 pg/100 mg fresh weight and its precision was less than 13.4%,indicating high sensitivity and good reproducibility of the method.Tests of our method in different plant matrices demonstrated its wide applicability.Collectively,these advantages will make our method helpful in clarifying the crosstalk networks of phytohormones. | Peiyong Xin Qiuhuan Guo Bingbing Li Shujing Cheng Jijun Yan Jinfang Chu | 2020 | Plant Communications2020,1,3: | 7 |
| 12 | Functional Metabolomics Reveals that Astragalus Polysaccharides Improve Lipids Metabolism through Microbial Metabolite 2-Hydroxybutyric Acid in Obese Mice显示文摘Polysaccharides are widely present in herbs with multiple activities,especially immunity regulation and metabolic benefits for metabolic disorders.However,the underlying mechanisms are not well under-stood.Functional metabolomics is increasingly used to investigate systemic effects on the host by iden-tifying metabolites with particular functions.This study explores the mechanisms underlying the metabolic benefits of Astragalus polysaccharides(APS)by adopting a functional metabolomics strategy.The effects of APS were determined in eight-week high-fat diet(HFD)-fed obese mice.Then,gas chromatography–time-of-flight mass spectrometry(GC–TOFMS)-based untargeted metabolomics was performed for an analysis of serum and liver tissues,and liquid chromatography–tandem mass spectrom-etry(LC–MS/MS)-based targeted metabolomics was performed.The potential functions of the metabo-lites were tested with in vitro and in vivo models of metabolic disorders.Our results first confirmed the metabolic benefits of APS in obese mice.Then,metabolomics analysis revealed that APS supplemen-tation reversed the HFD-induced metabolic changes,and identified 2-hydroxybutyric acid(2-HB)as a potential functional metabolite for APS activity that was significantly decreased by a HFD and reversed by APS.Further study indicated that 2-HB inhibited oleic acid(OA)-induced triglyceride(TG)accumula-tion.It was also found to stimulate the expression of proteins in lipid degradation in hepatocytes and TG lipolysis in 3T3-L1 cells.Moreover,it was found to reduce serum TG and regulate the proteins involved in lipid degradation in high-fat and high-sucrose(HFHS)-fed mice.In conclusion,our study demonstrates that the metabolic benefits of APS are at least partially due to 2-HB generation,which modulated lipid metabolism both in vitro and in vivo.Our results also highlight that functional metabolomics is practical for investigating the mechanism underlying the systemic benefits of plant polysaccharides. | Bingbing Li Ying Hong Yu Gu Shengjie Ye Kaili Hu Jian Yao Kan Ding Aihua Zhao Wei Jia Houkai Li | 2022 | Engineering2022,8,2: | 6 |
| 13 | Multifunctional dextran micelles as drug delivery carriers and magnetic resonance imaging probes显示文摘Multifunctional nanoparticles combining diagnostic and therapeutic agents into a single platform make cancer theranostics possible and have attracted wide interests in the field. In this study, a multifunctional nanocomposite based on dextran and superparamagnetic iron oxide nanoparticles(SPIO) was prepared for drug delivery and magnetic resonance imaging(MRI). Amphiphilic dextran was synthesized by grafting stearyl acid onto the carbohydrate backbone, and micelle was formed by the resulted amphiphilic dextran with low critical micelle concentration at 1.8 mg L-1. Doxorubicin(DOX) and a cluster of the manganese-doped iron oxide nanoparticles(Mn-SPIO)nanocrystals were then coencapsulated successfully inside the core of dextran micelles, resulting in nanocomposites with diameter at about 100 nm. Cell culture experiments demonstrated the potential of these Mn-SPIO/DOX nanocomposites as an effective multifunctional nanoplatform for the delivery of anticancer drug DOX with a loading content(DLC) of 16 %. Confocal laser scanning microscopyreveals that the Mn-SPIO/DOX had excellent internalization ability against MCF-7/Adr cells after 2-h labeling compared with free DOXáHCl. Under a 3.0-T MRI scanner, Mn-SPIO/DOX nanocomposite-labeled cells in gelatin phantom show much darker images than the control. Their transverse relaxation(T2) rate is also significantly higher than that of the control cells(33.9 versus 2.3 s-1). Our result offers an effective strategy to treat MCF-7/Adr at optimized low dosages with imaging capability. | Bingbing Lin Hongying Su Rongrong Jin Danyang Li Changqiang Wu Xin Jiang Chunchao Xia Qiyong Gong Bin Song Hua Ai | 2015 | Science Bulletin2015,60,14: | 6 |
| 14 | Genetic analysis of yield and fiber quality traits in upland cotton(Gossypium hirsutum L.) cultivated in different ecological regions of China显示文摘Background:Cotton is an important fiber crop worldwide.The yield potential of current genotypes of cotton can be exploited through hybridization.However,to develop superior hybrids with high yield and fiber quality traits,information of genetic control of traits is prerequisite.Therefore,genetic analysis plays pivotal role in plant breeding.Results:In present study,North Carolina II mating design was used to cross 5 female parents with 6 male parents to produce 30 intraspecific F1cotton hybrids.All plant materials were tested in three different ecological regions of China during the year of 2016-2017.Additive-dominance-environment(ADE)genetic model was used to estimate the genetic effects and genotypic and phenotypic correlation of yield and fiber quality traits.Results showed that yield traits except lint percentage were mainly controlled by genetic and environment interaction effects,whereas lint percentage and fiber quality traits were determined by main genetic effects.Moreover,dominant and additiveen vironine nt in teraction effects had more influence on yield traits,whereas additive and domi nance-e nviron ment interaction effects were found to be predominant for fiber traits.Broad-sense and its interaction heritability were significant for all yield and most of fiber quality traits.Narrow-sense and its interaction heritability were non-significant for boll number and seed cotton yield.Correlation analysis indicated that seed cotton yield had significant positive correlation with other yield attributes and non-significant with fiber quality traits.All fiber quality traits had signiflcant positive correlation with each other except micronaire.Conclusions:Results of current study provide important information about genetic control of yield and fiber quality traits.Further,this study identified that parental lines,e.g.,SJ48-1,ZB-1,851-2,and DT-8 can be utilized to improve yield and fiber quality traits in cotton. | SHAHZAD Kashif LI Xue QI Tingxiang GUO Liping TANG Huini ZHANG Xuexian WANG Hailin ZHANG Meng ZHANG Bingbing QIAO Xiuqin XING Chaozhu WU Jianyong | 2019 | Journal of Cotton Research2019,2,2: | 5 |
| 15 | Ultrabroad band microwave absorption from hierarchical MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)Tx hybrids via annealing treatment显示文摘Two-dimensional(2D)transition metal carbide MXene-based materials hold great potentials applied for new electromagnetic wave(EMW)absorbers.However,the application of MXenes in the field of electromagnetic wave absorption(EMA)is limited by the disadvantages of poor impedance matching,single loss mechanism,and easy oxidation.In this work,MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)T_(x)hybrids were prepared by the annealing-treated Mo_(2)TiC_(2)T_(x)MXene and uniform MoO_(3)and TiO_(2)oxides in-situ grew on Mo_(2)TiC_(2)T_(x)layers.At the annealing temperature of 300℃,the minimum reflection loss(RLmin)value of MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)T_(x)reaches-30.76 dB(2.3 mm)at 10.18 GHz with a significantly broadening effective absorption bandwidth(EAB)of 8.6 GHz(1.8 mm).The in-situ generated oxides creating numerous defects and heterogeneous interfaces enhance dipolar and interfacial polarizations and optimize the impedance matching of Mo_(2)TiC_(2)T_(x).Considering the excellent overall performance,the MoO_(3)/TiO_(2)/Mo_(2)TiC_(2)T_(x)hybrids can be a promising candidate for EMA. | Feiyue HU Fan ZHANG Xiaohan WANG Yaya LI Hailong WANG Rui ZHANG Hongxia LI Bingbing FAN | 2022 | Journal of Advanced Ceramics2022,11,9: | 5 |
| 16 | Reduction of polyethylenimine-coated iron oxide nanoparticles induced autophagy and cytotoxicity by lactosylation显示文摘Superparamagnetic iron oxide(SPIO)nanoparticles are excellent magnetic resonance contrast agents and surface engineering can expand their applications.When covered with amphiphilic alkyl-polyethyleneimine(PEI),the modified SPIO nanoparticles can be used as MRI visible gene/drug delivery carriers and cell tracking probes.However,the positively charged amines of PEI can also cause cytotoxicity and restricts their further applications.In this study,we used lactose to modify amphiphilic low molecular weight polyethylenimine(C_(12-)PEI_(2K))at different lactosylation degree.It was found that the N-alkyl-PEI-lactobionic acid wrapped SPIO nanocomposites show better cell viability without compromising their labelling efficacy as well as MR imaging capability in RAW 264.7 cells,comparing to the unsubstituted ones.Besides,we found the PEI induced cell autophagy can be reduced via lactose modification,indicating the increased cell viability might rely on down-regulating autophagy.Thus,our findings provide a new approach to overcome the toxicity of PEI wrapped SPIO nanocomposites by lactose modification. | Jiuju Du Wencheng Zhu Li Yang Changqiang Wu Bingbing Lin Jun Wu Rongrong Jin Taipeng Shen Hua Ai | 2016 | Regenerative Biomaterials2016,3,4: | 5 |
| 17 | Genome Editing as A Versatile Tool to Improve Horticultural Crop Qualities显示文摘The quality traits of horticultural crops,including the accumulation of nutrients and flavor substances,morphology,and texture,affect the palatability and nutritional value.For many years,efforts have been made to improve the quality of horticultural crops.The recent establishment of gene editing technology,with its potential applications in horticultural crops,provides a strategy for achieving this goal in a rapid and efficient manner.Here,we summarize research efforts aimed at improving horticultural crop quality through genome editing.We describe specific genome editing systems that have been used and traits that have been targeted in these efforts.Additionally,we discuss limiting factors and future perspectives of genome editing technology in improving horticultural crop qualities in both research and plant breeding.In summary,genome editing technology is emerging as a powerful tool for efficiently and rapidly improving horticultural crop quality,and we believe that the cautious application of genome editing in horticultural crops will generate new germplasms with improved quality in the near future. | Yating Chen Wenwen Mao Ting Liu Qianqian Feng Li Li Bingbing Li | 2020 | Horticultural Plant Journal2020,6,6: | 5 |
| 18 | Multifunctional SiC@SiO_(2) Nanofiber Aerogel with Ultrabroadband Electromagnetic Wave Absorption显示文摘Traditional ceramic materials are generally brittle and not flexible with high production costs,which seriously hinders their practical applications.Multifunctional nanofiber ceramic aerogels are highly desirable for applications in extreme environments,however,the integration of multiple functions in their preparation is extremely challenging.To tackle these challenges,we fabricated a multifunctional SiC@SiO_(2) nanofiber aerogel(SiC@SiO_(2) NFA)with a threedimensional(3D)porous cross-linked structure through a simple chemical vapor deposition method and subsequent heat-treatment process.The as-prepared SiC@SiO_(2) NFA exhibits an ultralow density(~11 mg cm^(-3)),ultra-elastic,fatigue-resistant and refractory performance,high temperature thermal stability,thermal insulation properties,and significant strain-dependent piezoresistive sensing behavior.Furthermore,the SiC@SiO_(2) NFA shows a superior electromagnetic wave absorption performance with a minimum refection loss(RL_(min))value of-50.36 d B and a maximum effective absorption bandwidth(EAB_(max))of 8.6 GHz.The successful preparation of this multifunctional aerogel material provides a promising prospect for the design and fabrication of the cutting-edge ceramic materials. | Limeng Song Fan Zhang Yongqiang Chen Li Guan Yanqiu Zhu Mao Chen Hailong Wang Budi Riza Putra Rui Zhang Bingbing Fan | 2022 | Nano-Micro Letters2022,14,9: | 4 |

| 20 | Mahalanobis distance-based fading cubature Kalman filter with augmented mechanism for hypersonic vehicle INS/CNS autonomous integration显示文摘Inertial Navigation System/Celestial Navigation System(INS/CNS)integration,especially for the tightly-coupled mode,provides a promising autonomous tactics for Hypersonic Vehicle(HV)in military demands.However,INS/CNS integration is a challenging research task due to its special characteristics such as strong nonlinearity,non-additive noise and dynamic complexity.This paper presents a novel nonlinear filtering method for INS/CNS integration by adopting the emerging Cubature Kalman Filter(CKF)to handle the strong INS error model nonlinearity caused by HV's high dynamics.It combines the state-augmentation technique into the nonlinear CKF to decrease the negative effect of non-additive noise in inertial measurements.Subsequently,a technique for the detection of dynamic model uncertainty is developed,and the augmented CKF is modified with fading memory to tackle dynamic model uncertainty by rigorously deriving the fading factor via the theory of Mahalanobis distance without artificial empiricism.Simulation results and comparison analysis prove that the proposed method can effectively curb the adverse impacts of non-additive noise and dynamic model uncertainty for inertial measurements,leading to improved performance for HV navigation with tightly-coupled INS/CNS integration. | Bingbing GAO Wenmin LI Gaoge HU Yongmin ZHONG Xinhe ZHU | 2022 | Chinese Journal of Aeronautics2022,35,5: | 4 |
