| 1 | The rice OsV4 encoding a novel pentatricopeptide repeat protein is required for chloroplast development during the early leaf stage under cold stress显示文摘Pentatricopeptide repeat(PPR)proteins,characterized by tandem arrays of a 35 amino acid motif,have been suggested to play central and broad roles in modulating the expression of organelle genes in plants.However,the molecular mechanisms of most rice PPR genes remains unclear.In this paper,we isolated and characterized a temperature-conditional virescent mutant,OsV4,in rice(Oryza sativa cultivar Jiahua1(WT,japonica rice variety)).The mutant displays albino phenotype and abnormal chloroplasts at the three leaf stage,which gradually turns green after the four leaf stage at a low temperature(20°C).But the mutant always develops green leaves and well-developed chloroplasts at a high temperature(32°C).Genetic and molecular analyses uncovered that OsV4 encodes a novel chloroplast-targeted PPR protein including four PPR motifs.Further investigations show that the mutant phenotype is associated with changes in chlorophyll content and chloroplast development.The OsV4transcripts only accumulate to high levels in young leaves,indicating that its expression is tissue-specific.In addition,transcript levels of some ribosomal components and plastid-encoded polymerase-dependent genes are dramatically reduced in the albino mutants grown at 20°C.These findings suggest that OsV4 plays an important role during early chloroplast development under cold stress in rice. | Xiaodi Gong Qianqian Su Dongzhi Lin Quan Jiang Jianlong Xu Jianhui Zhang Sheng Teng Yanjun Dong | 2014 | Journal of Integrative Plant Biology2014，56，4： | 19 |
| 2 | Transmission of climate change impacts from temperature change to grain harvests, famines and peasant uprisings in the historical China显示文摘Because of the complexity of social responses to climate change,as well as limitations of proxy data concerning interactions between climate change and human responses,the social impacts of past climate change and associated response mechanisms,thus,require further investigation.To shed light on the transmission of climate change impacts within historical Chinese society,we selected 30-year resolution sequences of temperature anomalies in eastern China and 10-year resolution sequences of grain harvest grades,famine indices,and frequencies of peasant uprisings in China over the past 2000 years.Using a food security perspective,we analyzed the impacts of temperature changes historically transmitted through Chinese production,population,and social subsystems,and differences in transmission characteristics between cold and warm units.Our results were as follows.(1)From 210 BC to 1910 AD,temperature changes in China were significantly positively correlated with grain harvest grades(correlation coefficient,0.338),and significantly negatively correlated with famine indices,and frequencies of peasant uprisings(correlation coefficients,-0.301 and-0.277,respectively).The correlation coefficients between famine indices and grain harvest grades or frequencies of peasant uprisings were very low.(2)There was a higher proportion of bumper or normal harvests(86.5%of the total decades),more moderate and mild famines(76%),and a lower proportion of peasant uprisings(33.3%)in the 30-year warm units.Conversely,there was a higher proportion of poor or normal harvests(70.7%),a greater proportion of moderate and severe famines(77.6%),and more peasant uprisings(51.7%)in the 30-year cold units.(3)Of the 23 main transmission pathways extending from temperature change to the social subsystem,13 occurred in cold units,of which 7 had an endpoint of peasant uprisings,and 10 occurred in warm units of which 3 had an endpoint of peasant uprisings.The main transmission pathways that were more likely to be associated with the impacts of temperature change were:Cold→poor harvests→severe famines→more uprisings;cold→poor harvests→moderate famines→more uprisings;warm→bumper harvests→mild famines→no uprisings;warm→bumper harvests→moderate harvests→no uprisings;warm→normal harvests→mild famines→no uprisings;and warm→normal harvests→moderate famines→no uprisings.(4)The transmission of the impacts of temperature change was a complex process.Within this process,famine was most prone to being modulated by human society.In the transmission pathways from the production to the social subsystem,there was a stepwise decrease in the occurrence rate of decades that were probably affected by climate change.In all cold units,10.4%of decades ending in more uprisings were most likely to be associated with the impacts of temperature change.In all warm units,47.9%of decades ending in no uprisings were most likely to be associated with the impacts of temperature change.This research can contribute a better understanding on the past interaction mechanisms and processes within the human-climate-ecosystem complex,as well as a better response to the impacts of the ongoing climate change. | FANG XiuQi SU Yun YIN Jun TENG JingChao | 2015 | Science China Earth Sciences2015，58，8： | 15 |

| 5 | Transarterial chemoembolization with PD-(L)1 inhibitors plus molecular targeted therapies for hepatocellular carcinoma(CHANCE001)显示文摘There is considerable potential for integrating transarterial chemoembolization(TACE),programmed death-(ligand)1(PD-[L]1)inhibitors,and molecular targeted treatments(MTT)in hepatocellular carcinoma(HCC).It is necessary to investigate the therapeutic efficacy and safety of TACE combined with PD-(L)1 inhibitors and MTT in real-world situations.In this nationwide,retrospective,cohort study,826 HCC patients receiving either TACE plus PD-(L)1 blockades and MTT(combination group,n=376)or TACE monotherapy(monotherapy group,n=450)were included from January 2018 to May 2021.The primary endpoint was progression-free survival(PFS)according to modified RECIST.The secondary outcomes included overall survival(OS),objective response rate(ORR),and safety.We performed propensity score matching approaches to reduce bias between two groups.After matching,228 pairs were included with a predominantly advanced disease population.Median PFS in combination group was 9.5 months(95%confidence interval[CI],8.4-11.0)versus 8.0 months(95%CI,6.6-9.5)(adjusted hazard ratio[HR],0.70,P=0.002).OS and ORR were also significantly higher in combination group(median OS,19.2[16.1-27.3]vs.15.7 months[13.0-20.2];adjusted HR,0.63,P=0.001;ORR,60.1%vs.32.0%;P<0.001).Grade 3/4 adverse events were observed at a rate of 15.8%and 7.5%in combination and monotherapy groups,respectively.Our results suggest that TACE plus PD-(L)1 blockades and MTT could significantly improve PFS,OS,and ORR versus TACE monotherapy for Chinese patients with predominantly advanced HCC in real-world practice,with an acceptable safety profile. | Hai-Dong Zhu Hai-Liang Li Ming-Sheng Huang Wei-Zhu Yang Guo-Wen Yin Bin-Yan Zhong Jun-Hui Sun Zhi-Cheng Jin Jian-Jian Chen Nai-Jian Ge Wen-Bin Ding Wen-Hui Li Jin-Hua Huang Wei Mu Shan-Zhi Gu Jia-Ping Li Hui Zhao Shu-Wei Wen Yan-Ming Lei Yu-Sheng Song Chun-Wang Yuan Wei-Dong Wang Ming Huang Wei Zhao Jian-Bing Wu Song Wang Xu Zhu Jian-Jun Han Wei-Xin Ren Zai-Ming Lu Wen-Ge Xing Yong Fan Hai-Lan Lin Zi-Shu Zhang Guo-Hui Xu Wen-Hao Hu Qiang Tu Hong-Ying Su Chuan-Sheng Zheng Yong Chen Xu-Ya Zhao Zhu-Ting Fang Qi Wang Jin-Wei Zhao Ai-Bing Xu Jian Xu Qing-Hua Wu Huan-Zhang Niu Jian Wang Feng Dai Dui-Ping Feng Qing-Dong Li Rong-Shu Shi Jia-Rui Li Guang Yang Hai-Bin Shi Jian-Song Ji Yu-E Liu Zheng Cai Po Yang Yang Zhao Xiao-Li Zhu Li-Gong Lu Gao-Jun Teng | 2023 | Signal Transduction and Targeted Therapy2023，8，3： | 7 |
| 6 | Effects of the Fhb1 gene on Fusarium head blight resistance and agronomic traits of winter wheat显示文摘The gene Fhb1 has been used in many countries to improve wheat Fusarium head blight(FHB) resistance. To make better use of this gene in the Yellow-Huai River Valleys Winter Wheat Zone(YHWZ), the most important wheat-producing region of China, it is desirable to elucidate its effects on FHB resistance and agronomic traits in different genetic backgrounds. Based on a diagnostic marker for Fhb1, six BC2 populations were developed by crossing dwarf-male-sterile(DMS)-Zhoumai 16 to three Fhb1 donors(Ningmai 9, Ningmai 13, and Jianyang 84) and backcrossing to Zhoumai 16 and Zhoumai16’s derivative cultivars(Lunxuan 136 and Lunxuan 13) using marker-assisted backcross breeding. The progenies were assessed for FHB resistance and major agronomic traits.The Fhb1 alleles were identified using the gene-specific molecular marker. The plants with the Fhb1-resistant genotype(Fhb1-R) in these populations showed significantly fewer infected spikelets than those with the Fhb1-susceptible genotype(Fhb1-S). When Lunxuan 136 was used as the recurrent parent, Fhb1-R plants showed significantly fewer infected spikelets per spike than Fhb1-R plants produced using Lunxuan 13 as the recurrent parent, indicating that the genetic backgrounds of Fhb1 influence the expression of FHB resistance. Fhb1-R plants from the DMS-Zhoumai 16/Ningmai 9//Zhoumai 16/3/Lunxuan 136 population showed the highest FHB resistance among the six populations and a significantly higher level of FHB resistance than the moderately susceptible control Huaimai 20. No significant phenotypic differences between Fhb1-R and Fhb1-S plants were observed for the eight agronomic traits investigated. These results suggest that it is feasible to improve FHB resistance of winter wheat withoutreducing yield potential by introgressing Fhb1 resistance allele into FHB-susceptible cultivars in the YHWZ. | Teng Li Hongjun Zhang Yiwen Huang Zhenqi Su Yun Deng Hongwei Liu Chunyan Mai Guangjun Yu Huili Li Liqiang Yu Tongquan Zhu Li Yang Hongjie Li Yang Zhou | 2019 | The Crop Journal2019，7，6： | 6 |
| 7 | Biodegradable magnesium-matrix composites:A review显示文摘Biodegradable magnesium alloys as new biomedical implant materials have been extensively studied because of their notable biodegradability over traditional bio-inert metals.However,the extreme degradation rate of pure magnesium leads to the loss of its mechanical integrity before the tissue recovers completely.The solutions to this challenge are as follows:(1)purification,(2)alloying,(3)surface modification,and(4)biodegradable magnesium-matrix composites(BMMCs)synthesis.Owing to the tunability of mechanical properties,the adjustability of degradation rate,and the improvement of biocompatibility,BMMCs reinforced with bioactive reinforcements have promising applications as a new generation of biomedical implants.In this review,the processing methods,Mg matrix,and reinforcement phases of BMMCs are discussed.Moreover,the review comprehensively discusses various BMMCs synthesized thus far,aiming to show the governing aspects of the achieved mechanical properties,corrosion behavior,and biocompatibility.Finally,this paper also discusses the research direction and further development areas for these materials. | Jin-long Su Jie Teng Zi-li Xu Yuan Li | 2020 | International Journal of Minerals,Metallurgy and Materials2020，27，6： | 5 |

| 10 | Numerical study of resonance induced by wave action on multiple rectangular boxes with narrow gaps显示文摘By introducing a source term into the Laplace equation, a two-dimensional fully nonlinear time-domain numerical wave flume(NWF) is developed to investigate the resonance induced by the interaction between waves and multiple objects with narrow gaps. In the numerical model, the fully nonlinear kinematic and dynamic boundary conditions are satisfied on the instantaneous free surface and the constant artificial damping is employed in the gaps to approximate the viscous dissipation due to vortex motion and flow separation. The computational domain is discretized using a higher-order boundary element method(HOBEM). The proposed model is firstly validated against the published experimental data and numerical results of the wave height in the narrow gap between two boxes, the wave heights in the two gaps of three boxes, and wave loads on the boxes.Then, the extensive numerical experiments are performed to study the influences of the number of the boxes and the gap spacing on the resonant frequency, reflected and transmitted wave heights and wave loads on the boxes. | NING Dezhi SU Xiaojie ZHAO Ming TENG Bin | 2015 | Acta Oceanologica Sinica2015，34，5： | 5 |
| 11 | Clonality and allelotype analyses of focal nodular hyperplasia compared with hepatocellular adenoma and carcinoma显示文摘AIM: To identify clonality and genetic alterations in focal nodular hyperplasia (FNH) and the nodules derived from it. METHODS: Twelve FNH lesions were examined. Twelve hepatocellular adenomas (HCAs) and 22 hepatocellular carcinomas (HCCs) were used as references. Nodules of different types were identified and isolated from FNH by microdissection. An X-chromosome inactivation assay was employed to describe their clonality status. Loss of heterozygosity (LOH) was detected, using 57 markers, for genetic alterations.RESULTS: Nodules of altered hepatocytes (NAH), the putative precursors of HCA and HCC, were found in all the FNH lesions. Polyclonality was revealed in 10 FNH lesions from female patients, and LOH was not detected in any of the six FNH lesions examined, the results apparently showing their polyclonal nature. In contrast, monoclonality was demonstrated in all the eight HCAs and in four of the HCCs from females, and allelic imbalances were found in the HCAs (9/9) and HCCs (15/18), with chromosomal arms 11p, 13q and 17p affected in the former, and 6q, 8p, 11p, 16q and 17p affected in the latter lesions in high frequencies (≥ 30%). Monoclonality was revealed in 21 (40%) of the 52 microdissected NAH, but was not found in any of the f ive ordinary nodules. LOH was found in all of the 13 NAH tested, being highly frequent at six loci on 8p, 11p, 13q and 17p. CONCLUSION: FNH, as a whole, is polyclonal, but some of the NAH lesions derived from it are already neoplastic and harbor similar allelic imbalances as HCAs. | Yi-Ran Cai Li Gong Xiao-Ying Teng Hong-Tu Zhang Cheng-Feng Wang Guo-Lian Wei Lei Guo Fang Ding Zhi-Hua Liu Qin-Jing Pan Qin Su | 2009 | World Journal of Gastroenterology2009，15，37： | 5 |
| 12 | 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 |

| 14 | Exosomes Released from Rabies Virus-Infected Cells May be Involved in the Infection Process显示文摘Exosomes are cell-derived vesicles that are secreted by many eukaryotic cells. It has recently attracted attention as vehicles of intercellular communication. Virus-infected cells release exosomes, which contain viral proteins, RNA, and pathogenic molecules. However, the role of exosomes in virus infection process remains unclear and needs to be further investigated.In this study, we aimed to evaluate the effects of exosomes on rabies virus infection. OptiPrep^(TM) density gradient centrifugation was used to isolate exosomes from rabies virus-infected cell culture supernatants. A rabies virus G protein enzyme-linked immunosorbent assay and acetylcholinesterase activity assays were performed to verify the centrifugation fractions. Exosomes were then characterized using transmission electron microscopy and Western blotting. Our results showed that rabies virus infection increased the release of exosomes. Treatment with GW4869 and si-Rab27 a, two exosomal secretion inhibitors, inhibited exosome release. Furthermore, the inhibitors reduced the levels of extracellular and intracellular viral RNA. These data indicated that exosomes may participate in the viral infection process. Moreover, our results establish a basis for future research into the roles of exosomes in rabies virus infection and as potential targets for developing new antiviral strategies. | Jingyu Wang Fan Wu Chuntian Liu Wenwen Dai Yawei Teng Weiheng Su Wei Kong Feng Gao Linjun Cai Ali Hou Chunlai Jiang | 2019 | Virologica Sinica2019，34，1： | 3 |

| 17 | Energy-efficient recovery of tetrahydrofuran and ethyl acetate by triple-column extractive distillation:entrainer design and process optimization显示文摘An energy-efficient triple-column extractive distillation process is developed for recovering tetrahydrofuran and ethyl acetate from industrial effluent.The process development follows a rigorous hierarchical design procedure that involves entrainer design,thermodynamic analysis,process design and optimization,and heat integration.The computer-aided molecular design method is firstly used to find promising entrainer candidates and the best one is determined via rigorous thermodynamic analysis.Subsequently,the direct and indirect triple-column extractive distillation processes are proposed in the conceptual design step.These two extractive distillation processes are then optimized by employing an improved genetic algorithm.Finally,heat integration is performed to further reduce the process energy consumption.The results indicate that the indirect extractive distillation process with heat integration shows the highest performance in terms of the process economics. | Ao Yang Yang Su Tao Shi Jingzheng Ren Weifeng Shen Teng Zhou | 2022 | Frontiers of Chemical Science and Engineering2022，16，2： | 3 |
| 18 | Crack status analysis for concrete dams based on measured entropy显示文摘The integrity and safety of concrete dams are seriously affected by the existing cracks in dam bodies, and some serious cracks may cause dam failure or disaster. The propagation of cracks in concrete dams is accompanied by changes in energy distribution, which can be represented by changes in the structure's system entropy. Therefore, the entropy theory can be used in analyzing the behavior of dam cracks. Due to the randomness and locality of crack propagation, it is difficult to predict the location of cracks by traditional monitoring methods. To solve this problem, the influence of spatial positions of monitoring points on inspection zones is represented by a weight index, and the weight index is determined by the distance measure method proposed in this paper. Through the weighted linear fusion method, the entropy of multiple monitoring points is obtained for analyzing the behavior of dam cracks in the selected zones. Meanwhile, the catastrophe theory is used as the variation criterion of an entropy sequence in order to predict the instability time of dam cracks. Case studies are put forward on a high arch dam, and the fusion entropy is calculated according to the monitoring data from strain gauges. Results show that the proposed method can effectively predict the occurrence time and location of dam cracks regardless of the layout of monitoring instruments, and it is a new way to analyze the occurrence and propagation of dam cracks. | WU Bang Bin WU Zhong Ru CHEN Bo SU Huai Zhi BAO Teng Fei WANG Shao Wei | 2016 | Science China(Technological Sciences)2016，59，5： | 3 |
| 19 | Experimental investigation on continuous N_(2) injection to improve light oil recovery in multi-wells fractured-cavity unit显示文摘The purpose of this experimental study is to evaluate the feasibility and oil recovery efficiency of continuous N_(2) injection in a multi-well fractured-cavity reservoir.In this study,the similar criterion of physical simulation was firstly discussed.In order to reveal the mechanism of remaining oil startup and production performance characteristic by continuous N_(2) injection,a visualized twodimensional fractured-cavity model and a three-dimensional pressure resistant model were designed and fabricated respectively based on the similar theory.And the 2D visualized physical experiments and 3D physical experiments were performed with the simulated oil and brine reservoir samples in Tahe oilfield.Four groups of experiments in 2D and 3D model were performed,each of which included bottom water depletion driving,water injection and N_(2) injection.The 2D visualized experiments indicated the main mechanism of N_(2) developing remaining oil was to occupy the high position and replace the attic oil due to gravitational differentiation.Furthermore,both the 2D and 3D experiments demonstrated that higher oil recovery factor could be achieved if N_(2) was injected through high positional wells.The 3D physical model is closer to the real reservoir condition,so the production performance can reflect the real field production process.This paper confirmed the efficiency of continuous N2 flooding in the light oil saturated fractured-cavity reservoir. | Wei Su Jirui Hou Teng Zhao Yuanyuan Xi Can Cui | 2017 | Petroleum2017，3，3： | 3 |
