| 1 | Risk assessment of Giardia in rivers of southern China based on continuous monitoring显示文摘The occurrence and risks of Giardia in China have been unclear to date,which has made it difficult to properly manage source water as well as to create reasonable drinking water standards.The levels of Giardia in river networks of several cities in Zhejiang Province,China were found to be in the range of 0-5 oocysts/10 L in the rainy season in 2008.The mortality due to Giardia infection for people in this region was calculated to be from 0 to 1.95 × 10?8 persons using a conditional probability equation.Based on multiple unboiled water intake routes,the disability-adjusted life years(DALYs) due to Giardia infection for people who consumed conventionally treated water was 0.625(95% CI:0.137-2.05) per 105 persons,with the symptom of hospitalization making the highest contribution to total DALYs(0.56 per 105 persons;95% CI:0.122-1.84).The DALYs decreased to 0.425(95% CI:0.137-2.05) per 105 persons per year for those consuming water treated with advanced technology.These values were lower than the acceptable risk(1.97 × 10?5 DALYs per year).This study revealed the risk of Giardia infection to the people in river networks of Zhejiang Province for the first time,and provides a method to evaluate the risk of Giardia infection.The results are useful for the modification of drinking water quality standards based on cost-benefit analysis. | Wei An Dongqing Zhang Shumin Xiao Jianwei Yu Min Yang | 2012 | Journal of Environmental Sciences2012，24，2： | 8 |
| 2 | Mammalian ALKBH1 serves as an N^6-mA demethylase of unpairing DNA显示文摘N^6-methyladenine(N^6-mA)of DNA is an emerging epigenetic mark in mammalian genome.Levels of N^6-mA undergo drastic fluctuation during early embryogenesis,indicative of active regulation.Here we show that the 2-oxoglutarate-dependent oxygenase ALKBH1 functions as a nuclear eraser of N^6-mA in unpairing regions(e.g.,SIDD,Stress-Induced DNA Double Helix Destabilization regions)of mammalian genomes.Enzymatic profiling studies revealed that ALKBH1 prefers bubbled or bulged DNAs as substrate,instead of single-stranded(ss-)or double-stranded(ds-)DNAs.Structural studies of ALKBH1 revealed an unexpected“stretch-out”conformation of its“Flip1”motif,a conserved element that usually bends over catalytic center to facilitate substrate base flipping in other DNA demethylases.Thus,lack of a bending“Flip1”explains the observed preference of ALKBH1 for unpairing substrates,in which the flipped N^6-mA is primed for catalysis.Co-crystal structural studies of ALKBH1 bound to a 21-mer bulged DNA explained the need of both flanking duplexes and a flipped base for recognition and catalysis.Key elements(e.g.,an ALKBH1-specificα1 helix)as well as residues contributing to structural integrity and catalytic activity were validated by structurebased mutagenesis studies.Furthermore,ssDNA-seq and DIP-seq analyses revealed significant co-occurrence of base unpairing regions with N^6-mA in mouse genome.Collectively,our biochemical,structural and genomic studies suggest that ALKBH1 is an important DNA demethylase that regulates genome N^6-mA turnover of unpairing regions associated with dynamic chromosome regulation. | Min Zhang Shumin Yang Raman Nelakanti Wentao Zhao Gaochao Liu Zheng Li Xiaohui Liu Tao Wu Andrew Xiao Haitao Li | 2020 | Cell Research2020，30，3： | 6 |
| 3 | Arbitrary polarization conversion dichroism metasurfaces for all-in-one full Poincare sphere polarizers显示文摘The control of polarization,an essential property of light,is of broad scientific and technological interest.Polarizers are indispensable optical elements for direct polarization generation.However,arbitrary polarization generation,except that of common linear and circular polarization,relies heavily on bulky optical components such as cascading linear polarizers and waveplates.Here,we present an effective strategy for designing all-in-one full Poincare sphere polarizers based on perfect arbitrary polarization conversion dichroism and implement it in a monolayer all-dielectric metasurface.This strategy allows preferential transmission and conversion of one polarization state located at an arbitrary position on the Poincare sphere to its handedness-flipped state while completely blocking its orthogonal state.In contrast to previous methods that were limited to only linear or circular polarization,our method manifests perfect dichroism of nearly 100%in theory and greater than 90%experimentally for arbitrary polarization states.By leveraging this attractive dichroism,our demonstration of the generation of polarization beams located at an arbitrary position on a Poincare sphere directly from unpolarized light can substantially extend the scope of meta-optics and dramatically promote state-of-the-art nanophotonic devices. | Shuai Wang Zi-Lan Deng Yujie Wang Qingbin Zhou Xiaolei Wang Yaoyu Cao Bai-Ou Guan Shumin Xiao Xiangping Li | 2021 | Light(Science & Applications)2021，10，2： | 6 |
| 4 | Bevacizumab biosimilar LY01008 compared with bevacizumab(Avastin)as first-line treatment for Chinese patients with unresectable,metastatic,or recurrent non-squamous non-small-cell lung cancer:A multicenter,randomized,double-blinded,phase Ⅲ trial显示文摘Background:Previous studies have demonstrated the preclinical pharmacological and toxicological consistency,and clinical pharmacokinetic equivalence of bevacizumab biosimilar LY01008 with reference bevacizumab(Avastin).This randomized controlled trial aimed to compare the efficacy and safety of LY01008 with Avastin in first-line treatment of Chinese patients with advanced or recurrent non-squamous non-small cell lung cancer(NSCLC).Methods:StageⅢB-ⅣNSCLC patients with evaluable lesions,good physical status,and adequate organ functions from 67 centers across China were randomized in a ratio of 1:1 to receive LY01008 or Avastin 15 mg/kg intravenously in combination with paclitaxel/carboplatin(combined treatment)for 4-6 cycles,followed by maintenance monotherapy with LY01008 until disease progression,intolerable toxicity,or death.The primary endpoint was objective response rate(ORR)in accordance with Response Evaluation Criteria in Solid Tumors(RECIST)version 1.1 confirmed by independent radiological review committees(IRRC).Secondary endpoints included disease control rate(DCR),duration of response(DoR),progression-free survival(PFS),overall survival(OS),and safety.This study was registered in Clinical Trials.gov(NCT03533127).Results:Between December 15^(th),2017,and May 15^(th),2019,a total of 649 patients were randomized to the LY01008(n=324)or Avastin(n=325)group.As of September 25th,2019 for primary endpoint analysis,589 patients received ORR evaluation,with a median number of combined treatment cycles of 5(range 1-6)andmedian duration of treatment of 3.0(range 0.0-5.1)months.ORRof responseevaluable patients in the LY01008 and Avastin groups were 48.5% and 53.0%,respectively.The stratified ORR ratio was 0.91(90%CI 0.80-1.04,within the prespecified equivalence margin of 0.75-1.33).Up to May 15^(th),2020,with a median follow-up of 13.6(range 0.8-28.4)months,no notable differences in DCR,median DoR,median PFS,median OS,and 1-year OS rate were observed between the LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,LY01008 and Avastin groups.There were no clinically meaningful differences in safety and immunogenicity across treatment groups.Conclusions:LY01008 demonstrated similarity to Avastin in terms of efficacy and safety in Chinese patients with advanced or recurrent non-squamous NSCLC.LY01008 combined with paclitaxel/carboplatin is expected to become a new treatment option for unresectable,metastatic,or recurrent non-squamous NSCLC patients in the first-line setting. | Yuankai Shi Kaijian Lei Yuming Jia Bingqiang Ni Zhiyong He Minghong Bi Xicheng Wang Jianhua Shi Ming Zhou Qian Sun Guolei Wang Dongji Chen Yongqian Shu Lianke Liu Zhongliang Guo Yong Liu Junquan Yang Ke Wang Ke Xiao LinWu Tienan Yi Debin Sun Mafei Kang Tianjiang Ma Yimin Mao Jinsheng Shi Tiegang Tang Yan Wang Puyuan Xing Dongqing Lv Wangjun Liao Zhiguo Luo Bin Wang Xiaohong Wu Xiaoli Zhu Shuhua Han Qisen Guo Rongyu Liu Zhiwei Lu Jianyong Zhang Jian Fang Changlu Hu Yinghua Ji Guolong Liu Hong Lu Dedong Wu Junhong Zhang Shuyang Zhu Zheng Liu Wensheng Qiu Feng Ye Yan Yu Yanqiu Zhao Qinhong Zheng Jun Chen Zhanyu Pan Yiping Zhang Wenjuan Lian Bo Jiang Bo Qiu Guojun Zhang Hua Zhang Yanju Chen Yuan Chen Hongbing Duan Manxiang Li Shengming Liu Lijun Ma Hongming Pan Xia Yuan Xueli Yuan Yulong Zheng Emei Gao Li Zhao Shumin Wang Can Wu | 2021 | Cancer Communications2021，41，9： | 5 |
| 5 | Risk assessment of Giardia from a full scale MBR sewage treatment plant caused by membrane integrity failure显示文摘Membrane bioreactors(MBR) are highly efficient at intercepting particles and microbes and have become an important technology for wastewater reclamation. However, many pathogens can accumulate in activated sludge due to the long residence time usually adopted in MBR, and thus may pose health risks when membrane integrity problems occur.This study presents data from a survey on the occurrence of water-borne Giardia pathogens in reclaimed water from a full-scale wastewater treatment plant with MBR experiencing membrane integrity failure, and assessed the associated risk for green space irrigation. Due to membrane integrity failure, the MBR effluent turbidity varied between 0.23 and 1.90 NTU over a period of eight months. Though this turbidity level still met reclaimed water quality standards(≤ 5 NTU), Giardia were detected at concentrations of 0.3 to 95 cysts/10 L, with a close correlation between effluent turbidity and Giardia concentration. All β-giardin gene sequences of Giardia in the WWTP influents were genotyped as Assemblages A and B, both of which are known to infect humans. An exponential dose–response model was applied to assess the risk of infection by Giardia. The risk in the MBR effluent with chlorination was9.83 × 10-3, higher than the acceptable annual risk of 1.0 × 10-4. This study suggested that membrane integrity is very important for keeping a low pathogen level, and multiple barriers are needed to ensure the biological safety of MBR effluent. | Yu Zhang Zhimin Chen Wei An Shumin Xiao Hongying Yuan Dongqing Zhang Min Yang | 2015 | Journal of Environmental Sciences2015，27，4： | 4 |
| 6 | Time-sequential color code division multiplexing holographic display with metasurface显示文摘Color metasurface holograms are powerful and versatile platforms for modulating the amplitude,phase,polarization,and other properties of light at multiple operating wavelengths.However,the current color metasurface holography can only realize static manipulation.In this study,we propose and demonstrate a multiplexing metasurface technique combined with multiwavelength code-division multiplexing(CDM)to realize dynamic manipulation.Multicolor code references are utilized to record information within a single metasurface and increase the information capacity and security for anticracks.A total of 48 monochrome images consisting of pure color characters and multilevel color video frames were reconstructed in dual polarization channels of the birefringent metasurface to exhibit high information density,and a video was displayed via sequential illumination of the corresponding code patterns to verify the ability of dynamic manipulation.Our approach demonstrates significant application potential in optical data storage,optical encryption,multiwavelengthversatile diffractive optical elements,and stimulated emission depletion microscopy. | Xin Li Qinmiao Chen Xue Zhang Ruizhe Zhao Shumin Xiao Yongtian Wang Lingling Huang | 2023 | Opto-Electronic Advances2023，6，8： | 3 |
| 7 | Phyllotaxis-inspired nanosieves with multiplexed orbital angular momentum显示文摘Nanophotonic platforms such as metasurfaces,achieving arbitrary phase profiles within ultrathin thickness,emerge as miniaturized,ultracompact and kaleidoscopic optical vortex generators.However,it is often required to segment or interleave independent sub-array metasurfaces to multiplex optical vortices in a single nano-device,which in turn affects the device’s compactness and channel capacity.Here,inspired by phyllotaxis patterns in pine cones and sunflowers,we theoretically prove and experimentally report that multiple optical vortices can be produced in a single compact phyllotaxis nanosieve,both in free space and on a chip,where one meta-atom may contribute to many vortices simultaneously.The time-resolved dynamics of on-chip interference wavefronts between multiple plasmonic vortices was revealed by ultrafast time-resolved photoemission electron microscopy.Our nature-inspired optical vortex generator would facilitate various vortex-related optical applications,including structured wavefront shaping,free-space and plasmonic vortices,and high-capacity information metaphotonics. | Zhongwei Jin David Janoschka Junhong Deng Lin Ge Pascal Dreher Bettina Frank Guangwei Hu Jincheng Ni Yuanjie Yang Jing Li Changyuan Yu Dangyuan Lei Guixin Li Shumin Xiao Shengtao Mei Harald Giessen Frank Meyer zu Heringdorf Cheng-Wei Qiu | 2021 | eLight2021，1，1： | 3 |
| 8 | Direct observation of chaotic resonances in optical microcavities显示文摘Optical microcavities play a significant role in the study of classical and quantum chaos.To date,most experimental explorations of their internal wave dynamics have focused on the properties of their inputs and outputs,without directly interrogating the dynamics and the associated mode patterns inside.As a result,this key information is rarely retrieved with certainty,which significantly restricts the verification and understanding of the actual chaotic motion.Here we demonstrate a simple and robust approach to directly and rapidly map the internal mode patterns in chaotic microcavities.By introducing a local index perturbation through a pump laser,we report a spectral response of optical microcavities that is proportional to the internal field distribution.With this technique,chaotic modes with staggered mode spacings can be distinguished.Consequently,a complete chaos assisted tunneling(CAT)and its time-reversed process are experimentally verified in the optical domain with unprecedented certainty. | Shuai Wang Shuai Liu Yilin Liu Shumin Xiao Zi Wang Yubin Fan Jiecai Han Li Ge Qinghai Song | 2021 | Light(Science & Applications)2021，10，8： | 3 |
| 9 | Characterization of DNA damage response deficiency in pancreatic cancer patients from China显示文摘To the editor,Pancreatic ductal adenocarcinoma(PDAC)has the worst prognosis among all common malignant solid tumors,with a 5-year overall survival(OS)rate of less than 10%[1].Few effective targets for anticancer ther-apy have been confirmed in pancreatic cancer.Recently,it was substantiated that pancreatic cancer patients carry-ing deleterious mutations of the DNA damage response(DDR)genes are more likely to benefit from platinum-based chemotherapy[2]and poly(adenosine diphosphate-ribose)polymerase(PARP)inhibitor[3]. | Xiaofei Zhang Tiebo Mao Bei Zhang Haiyan Xu Jiujie Cui Feng Jiao Dongqin Chen Yu Wang Jiong Hu Qing Xia Shumin Li Ming Yue Jingyu Ma Jiayu Yao Yongchao Wang Xiao Zhang Shiqing Chen Yuezong Bai Yuexiang Wang Xuebin Zhang Qiang Liu Yongwei Sun Deliang Fu Yingbin Liu Lei Xiong Liwei Wang | 2022 | Cancer Communications2022，42，1： | 2 |

| 12 | Improvement of the chirality near avoided resonance crossing in optical microcavity显示文摘Chirality is one of the important phenomena at the vicinity of exceptional point(EP). The conventional understanding is that the chirality is determined by asymmetrical scattering efficiency(?), which reaches to zero only when the resonance approaches EP. Here we study the possibility to enhance the chirality in open systems with a more robust mechanism. By combining chirality with avoided resonance crossing, we show that the chirality and ? can be dramatically modified. Taking a spiral shaped annular cavity as an example, we show that the chirality of optical resonances can be significantly improved when two sets of chiral states approach each other. The imbalance between counterclockwise(CCW) components and clockwise(CW) components has been enhanced by more than an order of magnitude. Our research provides a new route to tailor and control the chirality in open systems. | SONG QingHai GU ZhiYuan ZHANG Nan WANG KaiYang YI Ning Bo XIAO ShuMin | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，11： | 1 |
| 13 | Phase characterisation of metalenses显示文摘Metalenses have emerged as a new optical element or system in recent years,showing superior performance and abundant applications.However,the phase distribution of a metalens has not been measured directly up to now,hindering further quantitative evaluation of its performance.We have developed an interferometric imaging phase measurement system to measure the phase distribution of a metalens by taking only one photo of the interference pattern.Based on the measured phase distribution,we analyse the negative chromatic aberration effect of monochromatic metalenses and propose a feature size of metalenses.Different sensitivities of the phase response to wavelength between the Pancharatnam-Berry phase-based metalens and propagation phase-reliant metalens are directly observed in the experiment.Furthermore,through phase distribution analysis,it is found that the distance between the measured metalens and the brightest spot of focusing will deviate from the focal length when the metalens has a low nominal numerical aperture,even though the metalens is ideal without any fabrication error.We also use the measured phase distribution to quantitatively characterise the imaging performance of the metalens.Our phase measurement system will help not only designers optimise the designs of metalenses but also fabricants distinguish defects to improve the fabrication process,which will pave the way for metalenses in industrial applications. | Maoxiong Zhao Mu Ku Chen Ze-Peng Zhuang Yiwen Zhang Ang Chen Qinmiao Chen Wenzhe Liu Jiajun Wang Ze-Ming Chen Bo Wang Xiaohan Liu Haiwei Yin Shumin Xiao Lei Shi Jian-Wen Dong Jian Zi Din Ping Tsai | 2021 | Light(Science & Applications)2021，10，4： | 1 |
