| 1 | Carbon sequestration within millet phytoliths from dry-farming of crops in China显示文摘Phytoliths are noncrystalline minerals that form inside cells and cell walls of different parts of plants. Organic carbon in living cells can be occluded in phytoliths during plant growth. It has been documented that the occluded carbon within phytoliths is an important long-term terrestrial carbon reservoir that has a major role in the global carbon cycle. Common millet and foxtail millet have become typical dry-farming crops in China since the Neolithic Age. The study of carbon conservation within phytoliths in these crops could provide insights into anthropogenic influences on the carbon cycle. In this study, we analyzed the carbon content in phytoliths of common millet and foxtail millet. The results indicated that (1) common millet and foxtail millet contained 0.136% ± 0.070% and 0.129% ± 0.085% phytolith-occluded carbon (PhytOC) on a dry mass basis, respectively; (2) based on the mean annual production of common millet and foxtail millet in the last 10 years, the phytolith occluded carbon accumulation rate of common millet and foxtail millet was approximately 0.023 ± 0.015 and 0.020 ± 0.010 t CO 2 ha 1 a 1 , respectively; (3) assuming a similar phytolith occluded carbon accumulation rate as for common millet (the highest accumulation rate was 0.038 t CO 2 ha 1 a 1 ), this could result in the sequestration of 2.37 × 10 6 t CO 2 per year for the 62.4 × 10 6 ha dry-farming crops in China. Although there was a decline in the annual production rate and planting area of foxtail millet during 1949 to 2008, the total phytolith carbon sequestration rate was 7×10 6 t CO 2 within the 60-year period. However, phytolith occluded carbon has not yet been fully considered as a global carbon sink. Also, this carbon fraction is probably one of the best candidates for the missing carbon sink. | ZUO XinXin LU HouYuan | 2011 | Chinese Science Bulletin2011，56，32： | 27 |
| 2 | Ferroptosis is essential for diabetic cardiomyopathy and is prevented by sulforaphane via AMPK/NRF2 pathways显示文摘Herein,we define the role of ferroptosis in the pathogenesis of diabetic cardiomyopathy(DCM)by examining the expression of key regulators of ferroptosis in mice with DCM and a new ex vivo DCM model.Advanced glycation end-products(AGEs),an important pathogenic factor of DCM,were found to induce ferroptosis in engineered cardiac tissues(ECTs),as reflected through increased levels of Ptgs2 and lipid peroxides and decreased ferritin and SLC7 A11 levels.Typical morphological changes of ferroptosis in cardiomyocytes were observed using transmission electron microscopy.Inhibition of ferroptosis with ferrostatin-1 and deferoxamine prevented AGE-induced ECT remodeling and dysfunction.Ferroptosis was also evidenced in the heart of type 2 diabetic mice with DCM.Inhibition of ferroptosis by liproxstatin-1 prevented the development of diastolic dysfunction at 3 months after the onset of diabetes.Nuclear factor erythroid 2-related factor 2(NRF2)activated by sulforaphane inhibited cardiac cell ferroptosis in both AGE-treated ECTs and hearts of DCM mice by upregulating ferritin and SLC7 A11 levels.The protective effect of sulforaphane on ferroptosis was AMP-activated protein kinase(AMPK)-dependent.These findings suggest that ferroptosis plays an essential role in the pathogenesis of DCM;sulforaphane prevents ferroptosis and associated pathogenesis via AMPK-mediated NRF2 activation.This suggests a feasible therapeutic approach with sulforaphane to clinically prevent ferroptosis and DCM. | Xiang Wang Xinxin Chen Wenqian Zhou Hongbo Men Terigen Bao Yike Sun Quanwei Wang Yi Tan Bradley B.Keller Qian Tong Yang Zheng Lu Cai | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 20 |

| 4 | Electroacupuncture at He-Mu points reduces P2X_4 receptor expression in visceral hypersensitivity显示文摘Electroacupuncture at Shangjuxu (ST37) and Tianshu (ST25) was reported to improve visceral hypersensitivity in rats.Colorectal distension was utilized to generate a rat model of chronic visceral hypersensitivity in irritable bowel syndrome.Results showed that abdominal withdrawal reflex scores noticeably increased after model establishment.Simultaneously,P2X 4 receptor immunoreactivity significantly increased in the colon and spinal cord.Electroacupuncture and pinaverium bromide therapy both markedly decreased abdominal withdrawal reflex scores in rats with visceral hypersensitivity,and significantly decreased P2X 4 receptor immunoreactivity in the colon and spinal cord.These data suggest that electroacupuncture treatment can improve visceral hypersensitivity in rats with irritable bowel syndrome by diminishing P2X 4 receptor immunoreactivity in the colon and spinal cord. | Xinxin Guo Jifei Chen Yuan Lu Luyi Wu Zhijun Weng Ling Yang Yuhu Xin Xianming Lin Yi Liang Jianqiao Fang | 2013 | Neural Regeneration Research2013，8，22： | 9 |
| 5 | Discriminated sgRNAs-Based SurroGate System Greatly Enhances the Screening Efficiency of Plant Base-Edited Cells显示文摘The development of CRISPR/Cas9-mediated base editing has made genomic modification more efficient. However, selection of genetically modified cells from millions of treated cells, especially plant cells, is still challenging. In this study, an efficient surrogate reporter system based on a defective hygromycin resistance gene was established in rice to enrich base-edited cells. After step-by-step optimization, the Discriminated sgRNAs-based SurroGate system (DisSUGs) was established by artificially differentiating the editing abilities of a wild-type single guide RNA (sgRNA) targeting the surrogate reporter gene and an enhanced sgRNA targeting endogenous sites. The DisSUGs enhanced the efficiency of screening base-edited cells by 3- to 5-fold for a PmCDA1-based cytosine-to-tyrosine base editor (PCBE), and 2.5- to 6.5-fold for an adenine base editor (ABE) at endogenous targets. These targets showed editing efficiencies of <25% in the conventional systems. The DisSUGs greatly enhanced the frequency of homozygous substitutions and expanded the activity window slightly for both a PCBE and an ABE. Analyses of the total number of single-nucleotide variants from whole-genome sequencing revealed that, compared with the no-enrichment PCBE strategy, the DisSUGs did not alter the frequency of genome-wide sgRNA-independent off-target mutations, but slightly increased the frequency of target-dependent off-target mutations. Collectively, the DisSUGs developed in this study greatly enhances the efficiency of screening plant base-edited cells and will be a useful system in future applications. | Wen Xu Yongxing Yang Ya Liu Guiting Kang Feipeng Wang Lu Li Xinxin Lv Si Zhao Shuang Yuan Jinling Song Ying Wu Feng Feng Xiaoqing He Chengwei Zhang Wei Song Jiuran Zhao Jinxiao Yang | 2020 | Molecular Plant2020，13，1： | 8 |
| 6 | Micro/nano-structured TiO2 surface with dual-functional antibacterial effects for biomedical applications显示文摘Implant-associated infections are generally difficult to cure owing to the bacterial antibiotic resistance which is attributed to the widespread usage of antibiotics.Given the global threat and increasing influence of antibiotic resistance,there is an urgent demand to explore novel antibacterial strategies other than using antibiotics.Recently,using a certain surface topography to provide a more persistent antibacterial solution attracts more and more attention.However,the clinical application of biomimetic nano-pillar array is not satisfactory,mainly because its antibacterial ability against Gram-positive strain is not good enough.Thus,the pillar array should be equipped with other antibacterial agents to fulfill the bacteriostatic and bactericidal requirements of clinical application.Here,we designed a novel model substrate which was a combination of periodic micro/nano-pillar array and TiO2 for basically understanding the topographical bacteriostatic effects of periodic micro/nano-pillar array and the photocatalytic bactericidal activity of TiO2.Such innovation may potentially exert the synergistic effects by integrating the persistent topographical antibacterial activity and the non-invasive X-ray induced photocatalytic antibacterial property of TiO2 to combat against antibiotic-resistant implant-associated infections.First,to separately verify the topographical antibacterial activity of TiO2 periodic micro/nano-pillar array,we systematically investigated its effects on bacterial adhesion,growth,proliferation,and viability in the dark without involving the photocatalysis of TiO2.The pillar array with sub-micron motif size can significantly inhibit the adhesion,growth,and proliferation of Staphylococcus aureus(S.aureus)and Escherichia coli(E.coli).Such antibacterial ability is mainly attributed to a spatial confinement size-effect and limited contact area availability generated by the special topography of pillar array.Moreover,the pillar array is not lethal to S.aureus and E.coli in 24 h.Then,the X-ray induced photocatalytic antibacterial property of TiO2 periodic micro/nano-pillar array in vitro and in vivo will be systematically studied in a future work.This study could shed light on the direction of surface topography design for future medical implants to combat against antibiotic-resistant implant-associated infections without using antibiotics. | Xiang Ge Chengzu Ren Yonghui Ding Guang Chen Xiong Lu Kefeng Wang Fuzeng Ren Meng Yang Zhuochen Wang Junlan Li Xinxin An Bao Qian Yang Leng | 2019 | Bioactive Materials2019，4，1： | 8 |
| 7 | A novel lncRNA, Lnc-OC1, promotes ovarian cancer cell proliferation and migration by sponging miR-34a and miR-34c显示文摘Long non-coding RNAs(lncRNAs) have been reported to be of great importance in tumorigenesis and progression of a variety of cancers. However, the role of lncRNAs in ovarian cancer(OC) remains largely unknown. In the present study, we identified a novel lncRNA, LOC100288181(named as Lnc-OC1), which acted as a key regulator in the development and progression of OC. The combined Gene Expression Omnibus(GEO) database analysis revealed that Lnc-OC1 was significantly upregulated in OC tissues and Kaplan-Meier survival analysis confirmed that high Lnc-OC1 expression was associated with poor prognosis of OC patients. Importantly, we also demonstrated that knockdown of Lnc-OC1 suppressed cell proliferation, colony formation, invasion and migration in vitro and inhibited tumorigenicity in vivo.Mechanistically, Lnc-OC1 repressed the expression of endogenous miR-34 a and miR-34 c as a sponge and vice versa. Moreover, rescue experiments demonstrated that the oncogenic function of Lnc-OC1 at least partially depended on suppressing miR-34 a and miR-34 c. In conclusion, our results suggest that the LncOC1-miR-34 a/34 c axis may play a pivotal role in OC, and may serve as a potential diagnostic biomarker and a powerful therapeutic target for OC. | Fangfang Tao Xinxin Tian Mengxi Lu Zhiqian Zhang | 2018 | Journal of Genetics and Genomics2018，45，3： | 8 |
| 8 | Synergistic effect of MXene on the flame retardancy and thermal degradation of intumescent flame retardant biodegradable poly(lactic acid)composites显示文摘The effect of Ti3C2 MXene nanosheets on the intumescent flame retardant(IFR)poly(lactic acid)(PLA)composites was investigated among a series of PLA/IFR/MXene,which were prepared by melt blending 0-2.0 wt%MXene,10.0 wt%-12.0 wt%IFR and PLA together.The results of limiting oxygen index(LOI)and vertical burning(UL-94)discover that the combination of 0.5 wt%MXene and 11.5 wt%IFR synergistically improves the fire safety of PLA to reach UL-94 V-0 rating with LOI value of 33.0%.The PLA/IFR/MXene composites perform an obvious reduction in peak of heat release rate(HRR)in cone calorimeter tests(CCTs).Furthermore,the carbon residues after CCTs were characterized by scanning electron microscope(SEM),laser Raman spectroscopy(LRS),X-ray diffraction(XRD)and X-ray photoelectron spectroscopy(XPS).It is demonstrated that both the titanium composition of the MXene structure and the characteristics of the two-dimensional material enhance the PLA/IFR/MXene composite materials’ability to produce a dense barrier layer to resist burnout during thermal degradation. | Haowei Huang Dexuan Dong Weijie Li Xinya Zhang Li Zhang Ying Chen Xinxin Sheng Xiang Lu | 2020 | Chinese Journal of Chemical Engineering2020，28，7： | 7 |
| 9 | Molecular characteristics of the omp A gene of serotype B Chlamydia trachomatis in Qinghai Tibetan primary school students显示文摘To study the molecular characteristics of Chlamydia trachomatis, the major outer membrane protein gene(omp A) of C. trachomatis from primary school students with trachoma residing in the Qinghai Tibetan area was sequenced and compared with the same serotype in Gen Bank. In Jianshetang Primary School and Galeng Central Primary School in the Galeng Tibetan Township of Qinghai Haidong Sala Autonomous County, scraped samples were collected from the upper tarsal conjunctiva and lower conjunctival sac of both eyes of 45 students with trachoma, stored at 4°C, and transported to Beijing Tongren Hospital by air within 24 h. The samples were screened for C. trachomatis by real-time PCR. The omp A gene from the C. trachomatis-positive samples was amplified by nested PCR. The serotype was confirmed by National Center for Biotechnology Information(NCBI) BLAST search and homology analysis. The entire omp A gene sequence was compared with the corresponding gene sequences of serotype B strains available in Gen Bank. Of the 45 students aged 6–13 years with trachoma, 26 C. trachomatis-positive students were identified by the initial real-time PCR screening(average age,(9.09±1.63) years; sex ratio, 1.0), accounting for 57.78%(26/45). The cycle threshold values for real-time PCR were 16.79–37.77. Half(13/26) of C. trachomatis-positive students had a bacterial copy number of >105. The compliance rate of the omp A gene sequences with the C. trachomatis serotype B strains in Gen Bank was up to 99%. Two novel genetic mutations were found when the omp A gene was compared with those of the 11 serotype B strains in Gen Bank. The two non-synonymous mutations were located at(i) position 271 in the second constant domain, an adenine(A) to guanine(G) substitution(ACT?GCT), changing the amino acid at position 91 from threonine to alanine(Thr?Ala) in all 26 strains; and(ii) position 887 in the fourth variable domain, a cytosine(C) to thymine(T) substitution(GCA?GTA), changing the amino acid at residue 296 from alanine to valine(Ala?Val) in four of the 26 strains. Six mutations were identified relative to ATCC VR-573. The strains could be divided into two gene clusters according to the mutation at nucleotide position 887: CQZ-1(China Qinghai Tibetan-1) and CQZ-2(China Qinghai Tibetan-2). We thus detected two novel serotype B mutant strains of C. trachomatis among study subjects with trachoma. | Xue Li Shaoya Zhang Qingfeng Liang Mei Wang Ailian Hu Xiuyuan Li Benshan Yang Mingxin Zhang Ningli Wang Xinxin Lu | 2016 | Science China(Life Sciences)2016，59，6： | 6 |
| 10 | The spatial pattern of farming and factors influencing it during the Peiligang culture period in the middle Yellow River valley, China显示文摘The Peiligang culture(ca.7000–5000 cal BC)is the earliest Neolithic culture in the middle Yellow River valley and represents the emergence of cereal farming in the region[1].It has long been considered representative of millet farming[2],which requires a dry field,a certain amount of rainfall,and minimal crop management,but new records reveal that mixed farming of millet and rice(Oryza sp.)took place during this period[3].Therefore,it is possible | Can Wang Houyuan Lu Wanfa Gu Naiqin Wu Jianping Zhang Xinxin Zuo Fengjiang Li Daojing Wang Yajie Dong Songzhi Wang Yanfeng Liu Yingjian Bao Yayi Hu | 2017 | Science Bulletin2017，62，23： | 6 |
| 11 | In vitro and in vivo activity of D-serine in combination with β-lactam antibiotics against methicillin-resistant Staphylococcus aureus显示文摘As D-amino acids play important roles in the physiological metabolism of bacteria,combination of D-amino acids with antibiotics may provide synergistic antibacterial activity. The aim of the study was to evaluate in vitro and in vivo activity of D-serine alone and in combination withβ-lactams against methicillin-resistant Staphylococcus aureus(MRSA) strains, and to explore the possible sensitization mechanisms. The activity of D-serine, β-lactams alone and in combinations was evaluated both in vitro by standard MICs, time–kill curves and checkerboard assays, and in vivo by murine systemic infection model as well as neutropenic thigh infection model. An in vitro synergistic effect was demonstrated with the combination of D-serine and β-lactams against MRSA standard and clinical strains.Importantly, the combinations enhanced the therapeutic efficacy in the animal models as compared toβ-lactam alone groups. Initial mechanism study suggested possible revision of D-alanine-D-alanine residue to D-alanine-D-serine in peptidoglycan by adding of D-alanine in the medium, which may cause decreased affinity to PBPs during transpeptidation. In conclusion, D-serine had synergistic activity in combination with β-lactams against MRSA strains both in vitro and in vivo. Considering the relatively good safety of D-serine alone or in combination with β-lactams, D-serine is worth following up as new anti-MRSA infection strategies. | Qing Wang Yuemeng Lv Jing Pang Xue Li Xi Lu Xiukun Wang Xinxin Hu Tongying Nie Xinyi Yang Yan Q.Xiong Jiandong Jiang Congran Li Xuefu You | 2019 | Acta Pharmaceutica Sinica B2019，9，3： | 6 |
| 12 | Distribution and contamination of metals and biogenic elements in sediments from Zhifu Bay of the Yellow Sea,China显示文摘Metals and biogenic elements were analyzed from surface sediments of sixteen stations and a 32 cm core collected from Zhifu Bay in July 2009.High concentrations of biogenic silica(BSi)reflected the high diatom productivity in the Bay.Meanwhile,total organic carbon(TOC)in Zhifu Bay was mainly from terrestrial sources.All metals were lower than the marine sediment quality guidelines.Based on the vertical profiles of biogenic elements,there was a clear increase of TOC,total nitrogen(TN),and total phosphate(TP)between1985 and 2000.TN concentrations decreased after the start of the operation of the sewage treatment plant in 1998;however TOC and BSi remained at high levels.Metal concentrations showed a general increase from the bottom to the top of the core.Most anthropogenic metals reached a maximum during 1996 and 2000,and decreased after the startup of the sewage plant;however,they have increased again recently.The results from correlation analysis and principal component analysis show that industrial pollution is the main source of Cd,Cr,Cu,Ni,Pb and Zn contamination in Zhifu Bay,and Yantai Port and ship transportation also contribute a lot to Cd,Cu,Hg,and Pb pollution. | Zhaohui Wang Xinxin Lu Ke Zhang | 2016 | Journal of Environmental Sciences2016，28，3： | 6 |
| 13 | Hybrid nano-scale Au with ITO structure for a high-performance near-infrared silicon-based photodetector with ultralow dark current显示文摘An internal photoemission-based silicon photodetector detects light below the silicon bandgap at room temperature and can exhibit spectrally broad behavior,making it potentially suited to meet the need for a near-infrared pure Si photodetector.In this work,the implementation of a thin Au insertion layer into an ITO/n-Si Schottky photodetector can profoundly affect the barrier height and significantly improve the device performance.By fabricating a nanoscale thin Au layer and an ITO electrode on a silicon substrate,we achieve a well-behaved ITO/Au/n-Si Schottky diode with a record dark current density of 3.7×10^(−7) A/cm^(2) at−1 V and a high rectification ratio of 1.5×10^(8) at±1 V.Furthermore,the responsivity has been obviously improved without sacrificing the dark current performance of the device by decreasing the Au thickness.Such a silicon-based photodetector with an enhanced performance could be a promising strategy for the realization of a monolithic integrated pure silicon photodetector in optical communication. | Xinxin Li Zhen Deng Jun Li Yangfeng Li Linbao Guo Yang Jiang Ziguang Ma Lu Wang Chunhua Du Ying Wang Qingbo Meng Haiqiang Jia Wenxin Wang Wuming Liu Hong Chen | 2020 | Photonics Research2020，8，11： | 4 |
| 14 | Etiological characteristics of chlamydia trachoma conjunctivitis of Primary Boarding School students in the Qinghai Tibetan area显示文摘The aim of this study was to investigate the etiological characteristics of Chlamydia trachomatis conjunctivitis among resident students at primary schools in the Qinghai Tibetan area in order to understand the distribution of C. trachomatis and other pathogenic microorganisms, to detect the isolation rate of infectious pathogens, and to provide an evidence for further targeted efforts in the prevent of sporadic trachoma efforts. From two primary schools in Qinghai Province, ocular samples from 35 students who were clinically diagnosed as trachoma cases and 60 normal controls were obtained by swabbing their upper eyelids and lower conjunctival sacs. Samples were preserved at 4°C and airlifted to Beijing Tongren Hospital within 24 h. Real-time polymerase chain reaction(RT-PCR) was used to screen for C. trachomatis, and nested PCR was used to amplify a fragment of the omp A gene for serotype confirmation. Bacterial cultivation and sensitivity tests were conducted based on the 2015 version of the Clinical and Laboratory Standards Institute. Adenovirus, herpes simplex virus, cytomegalovirus, and Epstein-Barr virus were screened by RT-PCR. Among the 35 students with trachoma, 8 came from the Jianshetang Primary School and 27 came from the Central Primary School. Two novel C. trachomatis B serotypes(Gen Bank accession numbers KU737520 and KU737521) were detected based on a sequence analysis of the omp A gene. Single C. trachomatis infections accounted for 42.86%(9/21) of the cases, and infections with multiple bacteria, particularly Haemophilus influenzae, Staphylococcus aureus, Moraxella catarrhalis, and Streptococcus pneumoniae, accounted for the remaining 57.14%(12/21). Of the 14 C. trachomatis-negative samples, one was positive for adenoviral infection(serotype D) and 13 were positive for bacterial infections(H. influenzae, M. catarrhalis, S. pneumoniae, S. aureus, streptococci other than S. pneumoniae, Staphylococcus epidermidis, Corynebacterium, and Arthrobacterium). In addition to C. trachomatis, the other bacteria and virus that were detected in the boarding students of primary schools in the Qinghai Tibetan area should be emphasized in trachoma prevention and control. | Mei Wang Xinxin Lu Ailian Hu Mingxin Zhang Xue Li Shijing Deng Ningli Wang | 2016 | Science China(Life Sciences)2016，59，6： | 4 |
| 15 | Three-dimensional time-varying sliding mode guidance law against maneuvering targets with terminal angle constraint显示文摘This paper deals with the problem of intercepting maneuvering targets with terminal angle constraints for missiles subjected to three-dimensional non-decoupling engagement geometry.To achieve the finite-time interception and satisfactory overload characteristics, a time varying sliding mode control methodology is developed based on a time base generator function. The main feature of the proposed guidance law guarantees the Line-of-Sight(LOS) angles to converge to small neighborhoods of the desired values at the interception time. First, a fractional power extended state observer is used to estimate the unknown target acceleration, which can significantly reduce the adaptive switching gain. The fractional power extended state observer enjoys the advantage of better noise tolerance. Then, a newly designed sliding mode surface is constructed by introducing a time base generator function and the time-varying sliding mode guidance law is developed based on this time-varying sliding surface. The proposed guidance law significantly reduces the overload magnitudes. Numerical simulations are carried out to verify the performance of the proposed guidance law. | Xinxin WANG Hongqian LU Xianlin HUANG Yefeng YANG Zongyu ZUO | 2022 | Chinese Journal of Aeronautics2022，35，4： | 4 |

| 17 | Multifunctional HDPE/CNTs/PW composite phase change materials with excellent thermal and electrical conductivities显示文摘The risk of leakage and low thermal conductivity severely hinder the wide application of phase change materials(PCMs).In this work,the high-density polyethylene/carbon nanotubes(HDPE/CNTs)porous scaffolds were successfully fabricated via a sacrificial template method followed by the general melt blending and water solvent etching.Subsequently,a series of paraffin wax HDPE/CNTs/PW composite PCMs were obtained combined with the simple vacuum impregnation method.The obtained HDPE/CNTs porous scaffolds can effectively avoid the leakage of PW,meanwhile,the thermal conductivity and electrical conductivity of HDPE/CNTs/PW-3:7 are increased by 2.94 times and 13 orders of magnitude compared with the HDPE/PW-3:7 respectively,also,it exhibits high phase change enthalpy(153.95 J/g for melting enthalpy and 152.82 J/g for crystallization enthalpy).From the above perspectives,the HDPE/CNTs/PW-3:7 has promising potential value in the application of light-to-thermal conversion,electro-to-thermal conversion and thermal energy storage. | Xiaolong Li Xinxin Sheng Yongqiang Guo Xiang Lu Hao Wu Ying Chen Li Zhang Junwei Gu | 2021 | Journal of Materials Science & Technology2021，，27： | 4 |
| 18 | Study of infectious conjunctivitis among children in rural areas of Qinghai province显示文摘Infectious conjunctivitis is no longer a common eye disease in cities and developed areas, but in remote mountainous regions of China where living conditions are relatively under-developed, the occurrence of infectious conjunctivitis remains a public health issue. Here, we evaluate the ratio of infectious conjunctivitis among primary school students in the rural areas of Xunhua, Huangyuan, and Huzhu Counties in the Qinghai province of China, and report the microorganisms involved in causing infection. Of the 765 eligible primary school students, 694 participated to this study(a response rateof 90.7%), 381 boys and 313 girls, with a mean age of 7.52 years(range 7–9 years). A clinical diagnosis of infectious conjunctivitis was returned for 238 of the 694 children examined. The ratio of infectious conjunctivitis in Xunhua County(46.64%) was higher compared to that in Huangyuan(26.67%; P=0.03) and Huzhu Counties(23.61%; P=0.02). The leading cause of conjunctivitis was bacterial, followed by chlamydial and viral. Our results show that there is a high ratio of infectious conjunctivitis among rural primary school students in Qinghai province. | Qingfeng Liang Xinxin Lu Mei Wang Lei Tian Antoine Labbé Ailian Hu | 2016 | Science China(Life Sciences)2016，59，6： | 3 |
| 19 | An insight into failure mechanism of NASICON-structured Na3V2(PO4)3 in hybrid aqueous rechargeable battery显示文摘NASICON (Na-super-ionic-conductors)-structured materials have attracted extensive research interest due to their great application potential in secondary batteries. However, the mechanism of capacity fading for NASICON-structured electrode materials has been rarely studied. In this paper, we synthesized the NASICON-structured Na3V2(PO4)3/C composite by simple sol-gel and high-temperature solid-phase method and investigated its electrochemical performance in Na-Zn hybrid aqueous rechargeable batteries. After characterizing the structure, morphology and composition variations as well as the interfacial resistance changes of Na3V2(PO4)3/C cathode during cycling, we propose a mechanical and interfacial degradation mechanism for capacity fading of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. This work will shed light on enhancing the mechanical and in terfacial stability of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. | Xinxin Zhang Jun Ma Pu Hu Bingbing Chen Chenglong Lu Xinhong Zhou Pengxian Han Lihua Chen Guanglei Cui | 2019 | Journal of Energy Chemistry2019，28，5： | 3 |
| 20 | Multi-proxy evidence of environmental change related to collapse of the Liangzhu Culture in the Yangtze Delta,China显示文摘The Liangzhu Culture(5300–4300 cal.a BP)has been regarded as the culmination of the Neolithic Age in the Yangtze Delta and as an archaic state.However,the reason behind the collapse of the Liangzhu Culture remains controversial.Some scholars attributed it to social conflicts or foreign invasions,while others suggested that environmental deterioration,such as cold episodes,inundation and palaeo-typhoon events,disrupted the civilization.Notably,the yellowish silty sediments widely overlying the Liangzhu group sites have been presumed to be one of the vital clues to resolving these issues.The process and cause of their formation are key to understanding the decline in the Liangzhu Culture.In this study,two typical profiles composed of the Liangzhu cultural layer and yellowish silty sediments were collected in Liangzhu Ancient City.Multiple proxies,including pollen,phytoliths and diatoms,along with radiocarbon and optically stimulated luminescence dating and synthesized geochemical evidence from different sediments,were applied to reconstruct ecological and hydrological changes and discuss their linkage to cultural collapse.The regional ecology was typical freshwater wetlands during 4800–4400 cal.a BP,which facilitated rice farming and large-scale architectural engineering in Liangzhu Ancient City.Evidence from microfossils and dating of the yellowish silty sediments indicated that Liangzhu Ancient City was significantly affected by seawater after abandonment during 4300–3400 cal.a BP.Furthermore,geochemical evidence,including trace element and Sr-Nd isotopic compositions,suggested that the primary provenance of the yellowish silt was a mixture of sediments from the Qiantang River,East China Sea,Yangtze River and Yellow River,which had been transported to Liangzhu Ancient City by the Yellow Sea Coastal Current and a marine transgression.Therefore,based on evidence from archaeological sites and numerical simulation in the Yangtze Delta,it was supposed that the short-term accelerated relative sea-level rise at approximately 4400 cal.a BP caused a marine transgression around Taihu Lake,formed a large range of yellowish silty sediments,destroyed rice farming production,and ultimately led to the collapse of the Liangzhu Culture. | Keyang HE Houyuan LU Guoping SUN Xiang JI Yonglei WANG Kaikai YAN Xinxin ZUO Jiangping ZHANG Bin LIU Ningyuan WANG | 2021 | Science China Earth Sciences2021，64，6： | 3 |
