| 1 | Blocking of the PD-1/PD-L1 interaction by a novel cyclic peptide inhibitor for cancer immunotherapy显示文摘The interaction of PD-1/PD-L1 allows tumor cells to escape from immune surveillance.Clinical success of the antibody drugs has proven that blockade of PD-1/PD-L1 pathway is a promising strategy for cancer immunotherapy.Here,we developed a cyclic peptide C8 by using Ph.D.-C7 C phage display technology.C8 showed high binding affinity with h PD-1 and could effectively interfere the interaction of PD-1/PD-L1.Furthermore,C8 could stimulate CD8^(+)T cell activation in human peripheral blood mononuclear cells(PBMCs).We also observed that C8 could suppress tumor growth in CT26 and B16-OVA,as well as anti-PD-1 antibody resistant B16 mouse model.CD8^(+)T cells infiltration significantly increased in tumor microenvironment,and IFN-γsecretion by CD8^(+)T cells in draining lymph nodes also increased.Simultaneously,we exploited T cells depletion models and confirmed that C8 exerted anti-tumor effects via activating CD8^(+)T cells dependent manner.The interaction model of C8 with h PD-1 was simulated and confirmed by alanine scanning.In conclusion,C8 shows anti-tumor capability by blockade of PD-1/PD-L1 interaction,and C8 may provide an alternative candidate for cancer immunotherapy. | Wenjie Zhai Xiuman Zhou Mingxia Zhai Wanqiong Li Yunhui Ran Yixuan Sun Jiangfeng Du Wenshan Zhao Lingxiao Xing Yuanming Qi Yanfeng Gao | 2021 | Science China(Life Sciences)2021，64，4： | 5 |
| 2 | Temperature-induced Lifshitz transition in topological insulator candidate HfTe_5显示文摘The ongoing discoveries and studies of novel topological quantum materials have become an emergent and important field of condensed matter physics.Recently,HfTe_5 ignited renewed interest as a candidate of a novel topological material.The single-layer HfTe_5 is predicted to be a two-dimensional large band gap topological insulator and can be stacked into a bulk that may host a temperature-driven topological phase transition.Historically,HfTe_5 attracted considerable interest for its anomalous transport properties characterized by a peculiar resistivity peak accompanied by a sign reversal carrier type.The origin of the transport anomaly remains under a hot debate.Here we report the first high-resolution laser-based angle-resolved photoemission measurements on the temperature-dependent electronic structure in HfTe_5.Our results indicated that a temperature-induced Lifshitz transition occurs in HfTe_5,which provides a natural understanding on the origin of the transport anomaly in HfTe_5.In addition,our observations suggest that HfTe_5 is a weak topological insulator that is located at the phase boundary between weak and strong topological insulators at very low temperature. | Yan Zhang Chenlu Wang Guodong Liu Aiji Liang Lingxiao Zhao Jianwei Huang Qiang Gao Bing Shen Jing Liu Cheng Hu Wenjuan Zhao Genfu Chen Xiaowen Jia Li Yu Lin Zhao Shaolong He Fengfeng Zhang Shenjin Zhang Feng Yang Zhimin Wang Qinjun Peng Zuyan Xu Chuangtian Chen Xingjiang Zhou | 2017 | Science Bulletin2017，62，13： | 4 |
| 3 | A Nonresonant Hybridized Electromagnetic-Triboelectric Nanogenerator for Irregular and Ultralow Frequency Blue Energy Harvesting显示文摘As a promising renewable energy source,it is a challenging task to obtain blue energy,which is irregular and has an ultralow frequency,due to the limitation of technology.Herein,a nonresonant hybridized electromagnetic-triboelectric nanogenerator was presented to efficiently obtain the ultralow frequency energy.The instrument adopted the flexible pendulum structure with a precise design and combined the working principle of electromagnetism and triboelectricity to realize the all-directional vibration energy acquisition successfully.The results confirmed that the triboelectric nanogenerator(TENG)had the potential to deliver the maximum power point of about 470μW while the electromagnetic nanogenerator(EMG)can provide 523 mW at most.The conversion efficiency of energy of the system reached 48.48%,which exhibited a remarkable improvement by about 2.96 times,due to the elastic buffering effect of the TENG with the double helix structure.Furthermore,its ability to collect low frequency wave energy was successfully proven by a buoy in Jialing River.This woke provides an effective candidate to harvest irregular and ultralow frequency blue energy on a large scale. | Weibo Xie Lingxiao Gao Lingke Wu Xin Chen Fayang Wang Daqiao Tong Jian Zhang Jianyu Lan Xiaobin He Xiaojing Mu Ya Yang | 2021 | Research2021，，1： | 4 |
| 4 | Small changes in the length of diselenide bond-containing linkages exert great influences on the antitumor activity of docetaxel homodimeric prodrug nanoassemblies显示文摘Homodimeric prodrug-based self-assembled nanoparticles,with carrier-free structure and ultrahigh drug loading,is drawing more and more attentions.Homodimeric prodrugs are composed of two drug molecules and a pivotal linkage.The influence of the linkages on the self-assembly,in vivo fate and antitumor activity of homodimeric prodrugs is the focus of research.Herein,three docetaxel(DTX)homodimeric prodrugs are developed using different lengths of diselenide bond-containing linkages.Interestingly,compared with the other two linkages,the longest diselenide bond-containing linkage could facilitate the self-delivery of DTX prodrugs,thus improving the stability,circulation time and tumor targeting of prodrug nanoassemblies.Besides,the extension of linkages reduces the redox-triggered drug release and cytotoxicity of prodrug nanoassemblies in tumor cells.Although the longest diselenide bond-containing prodrug nanoassemblies possessed the lowest cytotoxicity to 4T1 cells,their stable nanostructure maintained intact during circulation and achieve the maximum accumulation of DTX in tumor cells,which finally“turned the table”.Our study illustrates the crucial role of linkages in homodimeric prodrugs,and gives valuable proposal for the development of advanced nano-DDS for cancer treatment. | Lingxiao Li Shiyi Zuo Fudan Dong Tian Liu Yanlin Gao Yinxian Yang Xin Wang Jin Sun Bingjun Sun Zhonggui He | 2021 | Asian Journal of Pharmaceutical Sciences2021，16，3： | 3 |
| 5 | Temporal and spatial variations of net primary productivity and its response to groundwater of a typical oasis in the Tarim Basin, China显示文摘Net primary productivity (NPP) of the vegetation in an oasis can reflect the productivity capacity of a plant community under natural environmental conditions. Owing to the extreme arid climate conditions and scarce precipitation in the arid oasis regions, groundwater plays a key role in restricting the development of the vegetation. The Qira Oasis is located on the southern margin of the Taklimakan Desert (Tarim Basin, China) that is one of the most vulnerable regions regarding vegetation growth and water scarcity in the world. Based on remote sensing images of the Qira Oasis and daily meteorological data measured by the ground stations during the period 2006-2019, this study analyzed the temporal and spatial patterns of NPP in the oasis as well as its relation with the variation of groundwater depth using a modified Carnegie Ames Stanford Approach (CASA) model. At the spatial scale, NPP of the vegetation decreased from the interior of the Qira Oasis to the margin;at the temporal scale, NPP of the vegetation in the oasis fluctuated significantly (ranging from 29.80 to 50.07 g C/(m2•month)) but generally showed an increasing trend, with the average increase rate of 0.07 g C/(m2•month). The regions with decreasing NPP occupied 64% of the total area of the oasis. During the study period, NPP of both farmland and grassland showed an increasing trend, while that of forest showed a decreasing trend. The depth of groundwater was deep in the south of the oasis and shallow in the north, showing a gradual increasing trend from south to north. Groundwater, as one of the key factors in the surface change and evolution of the arid oasis, determines the succession direction of the vegetation in the Qira Oasis. With the increase of groundwater depth, grassland coverage and vegetation NPP decreased. During the period 2008-2015, with the recovery of groundwater level, NPP values of all types of vegetation with different coverages increased. This study will provide a scientific basis for the rational utilization and sustainable management of groundwater resources in the oasis. | SUN Lingxiao YU Yang GAO Yuting ZHANG Haiyan YU Xiang HE Jing WANG Dagang Ireneusz MALIK Malgorzata WISTUBA YU Ruide | 2021 | Journal of Arid Land2021，13，11： | 2 |
| 6 | Resequencing of sweetpotato germplasm resources reveals key loci associated with multiple agronomic traits显示文摘Sweetpotato is an important crop that exhibits hexaploidy and high heterozygosity,which limits gene mining for important agronomic traits.Here,314 sweetpotato germplasm resources were deeply resequenced,and 4599509 SNPs and 846654 InDels were generated,among which 196124 SNPs were nonsynonymous and 9690 InDels were frameshifted.Based on the Indels,genome-wide marker primers were designed,and 3219 of 40366 primer pairs were selected to construct the core InDel marker set.The molecular ID of 104 sweetpotato samples verified the availability of these primers.The sweetpotato population structures were then assessed through multiple approaches using SNPs,and diverse approaches demonstrated that population stratification was not obvious for most Chinese germplasm resources.As many as 20 important agronomic traits were evaluated,and a genome-wide association study was conducted on these traits.A total of 19 high-confidence loci were detected in both models.These loci included several candidate genes,such as IbMYB1,IbZEP1,and IbYABBY1,which might be involved in anthocyanin metabolism,carotenoid metabolism,and leaf morphogenesis,respectively.Among them,IbZEP1 and IbYABBY1 were first reported in sweetpotato.The variants in the promoter and the expression levels of IbZEP1 were significantly correlated with f lesh color(orange or not orange)in sweetpotato.The expression levels of IbYABBY1 were also correlated with leaf shape.These results will assist in genetic and breeding studies in sweetpotato. | Shizhuo Xiao Xibin Dai Lingxiao Zhao Zhilin Zhou Lukuan Zhao Pan Xu Bingqian Gao An Zhang Donglan Zhao Rui Yuan Yao Wang Jie Wang Qinglian Li Qinghe Cao | 2023 | Horticulture Research2023，10，1： | 1 |
| 7 | Green‑Solvent Processed Blade‑Coating Organic Solar Cells with an Efficiency Approaching 19%Enabled by Alkyl‑Tailored Acceptors显示文摘Power-conversion-efficiencies(PCEs)of organic solar cells(OSCs)in laboratory,normally processed by spin-coating technology with toxic halogenated solvents,have reached over 19%.However,there is usually a marked PCE drop when the bladecoating and/or green-solvents toward large-scale printing are used instead,which hampers the practical development of OSCs.Here,a new series of N-alkyl-tailored small molecule acceptors named YR-SeNF with a same molecular main backbone are developed by combining selenium-fused central-core and naphthalene-fused endgroup.Thanks to the N-alkyl engineering,NIR-absorbing YR-SeNF series show different crystallinity,packing patterns,and miscibility with polymeric donor.The studies exhibit that the molecular packing,crystallinity,and vertical distribution of active layer morphologies are well optimized by introducing newly designed guest acceptor associated with tailored N-alkyl chains,providing the improved charge transfer dynamics and stability for the PM6:L8-BO:YRSeNF-based OSCs.As a result,a record-high PCE approaching 19%is achieved in the blade-coating OSCs fabricated from a greensolvent o-xylene with high-boiling point.Notably,ternary OSCs offer robust operating stability under maximum-power-point tracking and well-keep>80%of the initial PCEs for even over 400 h.Our alkyl-tailored guest acceptor strategy provides a unique approach to develop green-solvent and blade-coating processed high-efficiency and operating stable OSCs,which paves a way for industrial development. | Hairui Bai Ruijie Ma Wenyan Su Top Archie Dela Pea Tengfei Li Lingxiao Tang Jie Yang Bin Hu Yilin Wang Zhaozhao Bi Yueling Su Qi Wei Qiang Wu Yuwei Duan Yuxiang Li Jiaying Wu Zicheng Ding Xunfan Liao Yinjuan Huang Chao Gao Guanghao Lu Mingjie Li Weiguo Zhu Gang Li Qunping Fan Wei Ma | 2023 | Nano-Micro Letters2023，15，12： | 1 |

| 9 | Proteome-Wide Profiling of the Covalent-Druggable Cysteines with a Structure-Based Deep Graph Learning Network显示文摘Covalent ligands have attracted increasing attention due to their unique advantages,such as long residence time,high selectivity,and strong binding affinity.They also show promise for targets where previous efforts to identify noncovalent small molecule inhibitors have failed.However,our limited knowledge of covalent binding sites has hindered the discovery of novel ligands.Therefore,developing in silico methods to identify covalent binding sites is highly desirable.Here,we propose DeepCoSI,the first structure-based deep graph learning model to identify ligandable covalent sites in the protein.By integrating the characterization of the binding pocket and the interactions between each cysteine and the surrounding environment,DeepCoSI achieves state-of-the-art predictive performances.The validation on two external test sets which mimic the real application scenarios shows that DeepCosI has strong ability to distinguish ligandable sites from the others.Finally,we profiled the entire set of protein structures in the RCSB Protein Data Bank(PDB)with DeepCoSI to evaluate the ligandability of each cysteine for covalent ligand design,and made the predicted data publicly available on website. | Hongyan Du Dejun Jiang Junbo Gao Xujun Zhang Lingxiao Jiang Yundian Zeng Zhenxing Wu Chao Shen Lei Xu Dongsheng Cao Tingjun Hou Peichen Pan | 2022 | Research2022，，4： | 1 |

| 12 | Uniformity Control of Scanned Beam in 300 MeV Proton and Heavy Ion Accelerator Complex at SESRI显示文摘In recent years,heavy ion accelerator technology has been rapidly developing worldwide and widely applied in the fields of space radiation simulation and particle therapy.Usually,a very high uniformity in the irradiation area is required for the extracted ion beams,which is crucial because it directly affects the experimental precision and therapeutic effect.Specifically,ultra-large-area and high-uniformity scanning are crucial requirements for spacecraft radiation effects assessment and serve as core specification for beamline terminal design.In the 300 MeV proton and heavy ion accelerator complex at the Space Environment Simulation and Research Infrastructure(SESRI),proton and heavy ion beams will be accelerated and ultimately delivered to three irradiation terminals.In order to achieve the required large irradiation area of 320 mm×320 mm,horizontal and vertical scanning magnets are used in the extraction beam line.However,considering the various requirements for beam species and energies,the tracking accuracy of power supplies(PSs),the eddy current effect of scanning magnets,and the fluctuation of ion bunch structure will reduce the irradiation uniformity.To mitigate these effects,a beam uniformity optimization method based on the measured beam distribution was proposed and applied in the accelerator complex at SESRI.In the experiment,the uniformity is successfully optimized from 75%to over 90%after five iterations of adjustment to the PS waveforms.In this paper,the method and experimental results were introduced. | HOU Lingxiao YUAN Youjin SHEN Guodong RUAN Shuang LIU Jie ZHU Yunpeng WANG Geng GUO Hongliang LYU Mingbang GAO Daqing XU Zhiguo SHENG Lina YANG Jiancheng | 2024 | 原子能科学技术2024，58，4： | 0 |

| 14 | Epidemiological and clinical features,treatment status,and economic burden of traumatic spinal cord injury in China:a hospital-based retrospective study显示文摘Traumatic spinal cord injury is potentially catastrophic and can lead to permanent disability or even death.China has the largest population of patients with traumatic spinal cord injury.Previous studies of traumatic spinal cord injury in China have mostly been regional in scope;national-level studies have been rare.To the best of our knowledge,no national-level study of treatment status and economic burden has been performed.This retrospective study aimed to examine the epidemiological and clinical features,treatment status,and economic burden of traumatic spinal cord injury in China at the national level.We included 13,465 traumatic spinal cord injury patients who were injured between January 2013 and December 2018 and treated in 30 hospitals in 11 provinces/municipalities representing all geographical divisions of China.Patient epidemiological and clinical features,treatment status,and total and daily costs were recorded.Trends in the percentage of traumatic spinal cord injuries among all hospitalized patients and among patients hospitalized in the orthopedic department and cost of care were assessed by annual percentage change using the Joinpoint Regression Program.The percentage of traumatic spinal cord injuries among all hospitalized patients and among patients hospitalized in the orthopedic department did not significantly change overall(annual percentage change,-0.5%and 2.1%,respectively).A total of 10,053(74.7%)patients underwent surgery.Only 2.8%of patients who underwent surgery did so within 24 hours of injury.A total of 2005(14.9%)patients were treated with high-dose(≥500 mg)methylprednisolone sodium succinate/methylprednisolone(MPSS/MP);615(4.6%)received it within 8 hours.The total cost for acute traumatic spinal cord injury decreased over the study period(-4.7%),while daily cost did not significantly change(1.0%increase).Our findings indicate that public health initiatives should aim at improving hospitals’ability to complete early surgery within 24 hours,which is associated with improved sensorimotor recovery,increasing the awareness rate of clinical guidelines related to high-dose MPSS/MP to reduce the use of the treatment with insufficient evidence. | Hengxing Zhou Yongfu Lou Lingxiao Chen Yi Kang Lu Liu Zhiwei Cai David BAnderson Wei Wang Chi Zhang Jinghua Wang Guangzhi Ning Yanzheng Gao Baorong He Wenyuan Ding Yisheng Wang Wei Mei Yueming Song Yue Zhou Maosheng Xia Huan Wang Jie Zhao Guoyong Yin Tao Zhang Feng Jing Rusen Zhu Bin Meng Li Duan Zhongmin Zhang Desheng Wu Zhengdong Cai Lin Huang Zhanhai Yin Kainan Li Shibao Lu Shiqing Feng | 2024 | Neural Regeneration Research2024，19，5： | 0 |
| 15 | Efficient option pricing with a unary-based photonic computing chip and generative adversarial learning显示文摘In the modern financial industry system,the structure of products has become more and more complex,and the bottleneck constraint of classical computing power has already restricted the development of the financial industry.Here,we present a photonic chip that implements the unary approach to European option pricing,in combination with the quantum amplitude estimation algorithm,to achieve quadratic speedup compared to classical Monte Carlo methods.The circuit consists of three modules:one loading the distribution of asset prices,one computing the expected payoff,and a third performing the quantum amplitude estimation algorithm to introduce speedups.In the distribution module,a generative adversarial network is embedded for efficient learning and loading of asset distributions,which precisely captures market trends.This work is a step forward in the development of specialized photonic processors for applications in finance,with the potential to improve the efficiency and quality of financial services. | HUI ZHANG LINGXIAO WAN SERGI RAMOS-CALDERER YUANCHENG ZHAN WAI-KEONG MOK HONG CAI FENG GAO XIANSHU LUO GUO-QIANG LO LEONG CHUAN KWEK JOSÉIGNACIO LATORRE AI QUN LIU | 2023 | Photonics Research2023，11，10： | 0 |
| 16 | Synergetic lethal energy depletion initiated by cancer cell membrane camouflaged nano-inhibitor for cancer therapy显示文摘Mitochondrial bioenergy plays a vital role in the occurrence and development of cancer.Although strategies to impede mitochondrial energy supply have been rapidly developed,the anticancer efficacy is still far from satisfactory,mainly attributed to the hybrid metabolic pathways of mitochondrial oxidative phosphorylation(OXPHOS)and glycolysis.Herein,we construct a cancer cell membrane camouflaged nano-inhibitor,mTPPa-Sy nanoparticle(NP),which co-encapsulates OXPHOS inhibitor(mitochondrial-targeting photosensitizers:TPPa)and glycolysis inhibitor(syrosingopine(Sy))for synergistically blocking the two different energy pathways.The mTPPa-Sy NPs exhibit precision tumor-targeting due to the high affinity between the biomimic membrane and the homotypic cancer cells.Under laser irradiation,the mitochondrial-targeting TPPa,which is synthesized by conjugating pyropheophorbide a(PPa)with triphenylphosphin,produces excessive reactive oxygen species(ROS)and further disrupts the OXPHOS.Interestingly,OXPHOS inhibition reduces O_(2) consumption and improves ROS production,further constructing a closed-loop OXPHOS inhibition system.Moreover,TPPa-initiated OXPHOS inhibition in combination with the Sytriggered glycolysis inhibition results in lethal energy depletion,significantly suppressing tumor growth even after a single treatment.Our findings highlight the necessity and effectiveness of synergetic lethal energy depletion,providing a prospective strategy for efficient cancer therapy. | Fudan Dong Qikun Jiang Lingxiao Li Tian Liu Shiyi Zuo Lin Gao Mengna Fang Yanlin Gao Bingjun Sun Cong Luo Zhonggui He Jin Sun | 2022 | Nano Research2022，15，4： | 0 |
| 17 | Photoluminescence manipulation in two-dimensional transition metal dichalcogenides显示文摘Two-dimensional transition metal dichalcogenides(TMDCs)have been regarded as an intriguing platform for exploring novel physical phenomena and optoelectronic devices due to their excitonic emission characteristics derived from the atomic thin thickness and reduced dielectric screening effect.Notably,monolayer TMDCs with a direct bandgap exhibiting strong photoluminescence(PL)are promising candidates for the light-emitting devices,while the interlayer excitons in heterostructures hold great potential for the photonic chips and optical communication applications.However,the non-ideal photoluminescent intensity and quality due to the ultrathin thickness and high defect density of experimentally obtained monolayer TMDCs limit the further development for the light-emission applications.Here,we summarize the research progress on the PL manipulation of the excitonic emission in TMDCs,where the PL intensity enhancement and emission wavelength regulation are included.The concept and characteristics of excitons are overviewed firstly,followed by the discussion on the evaluation and characterization of excitonic emission.The state-of-the-art progress on the manipulation of the neutral excitons and interlayer excitons PL are then summarized.Finally,the challenges and prospects are proposed. | Minglang Gao Lingxiao Yu Qian Lv Feiyu Kang Zheng-Hong Huang Ruitao Lv | 2023 | Journal of Materiomics2023，9，4： | 0 |
