| 1 | Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection. | Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu | 2020 | Science China(Life Sciences)2020，63，3： | 157 |
| 2 | Recent advances in wireless epicortical and intracortical neuronal recording systems显示文摘An implantable brain-computer interface(BCI)has proven to be effective in the field of sensory and motor function restoration and in the treatment of neurological disorders.Using a BCI recording system,we can transform current methods of human interaction with machines and the environment,especially to help those with cognitive and mobility disabilities regain mobility and reintegrate into society.However,most reported work has focused on a simple aspect of the whole system,such as electrodes,circuits,or data transmission,and only a very small percentage of systems are wireless.A miniature,lightweight,wireless,implantable microsystem is key to realizing long-term,real-time,and stable monitoring on freely moving animals or humans in their natural conditions.Here,we summarize typical wireless recording systems,from recording electrodes,processing chips and controllers,wireless data transmission,and power supply to the system-level package for either epicortical electrocorticogram(ECoG)or intracortical local field potentials(LFPs)/spike acquisition,developed in recent years.Finally,we conclude with our vision of challenges in next-generation wireless neuronal recording systems for chronic and safe applications. | Bowen JI Zekai LIANG Xichen YUAN Honglai XU Minghao WANG Erwei YIN Zhejun GUO Longchun WANG Yuhao ZHOU Huicheng FENG Honglong CHANG Jingquan LIU | 2022 | Science China(Information Sciences)2022，65，4： | 2 |
| 3 | StRAP2.3, an ERF-Ⅶ transcription factor, directly activates StInvInh2 to enhance cold-induced sweetening resistance in potato显示文摘Potato invertase inhibitor(StInvInh2)positively regulates cold-induced sweetening(CIS)resistance by inhibiting the activity of vacuolar invertase.The distinct expression patterns of StInvInh2 have been thoroughly characterized in different potato genotypes,but the related CIS ability has not been characterized.The understanding of the regulatory mechanisms that control StInvInh2 transcription is unclear.In this study,we identified an ERF‐Ⅶ transcription factor,StRAP2.3,that directly regulates StInvInh2 to positively modulate CIS resistance.Acting as a nuclear-localized transcriptional activator,StRAP2.3 directly binds the ACCGAC cis-element in the promoter region of StInvInh2,enabling promoter activity.Overexpression of StRAP2.3 in CIS-sensitive potato tubers induced StInvInh2 mRNA abundance and increased CIS resistance.In contrast,silencing StRAP2.3 in CIS-resistant potato tubers repressed the expression of StInvInh2 and decreased CIS resistance.We conclude that cold-responsive StInvInh2 is due to the binding of StRAP2.3 to the ACCGAC cis-element in the promoter region of StInvInh2.Overall,these findings indicate that StRAP2.3 directly regulates StInvInh2 to positively modulate CIS resistance,which may provide a strategy to improve the processing quality of potatoes. | Weiling Shi Yuhao Song Tiantian Liu Qiuqin Ma Wang Yin Yuchen Shen Tengfei Liu Chunyan Jiang Kai Zhang Dianqiu Lv Botao Song Jichun Wang Xun Liu | 2021 | Horticulture Research2021，8，1： | 1 |
| 4 | Manipulating cavity photon dynamics by topologically curved space显示文摘Asymmetric microcavities supporting Whispering-gallery modes(WGMs)are of great significance for on-chip optical information processing.We establish asymmetric microcavities on topologically curved surfaces,where the geodesic light trajectories completely reconstruct the cavity mode features.The curvature-mediated photon-lifetime engineering enables the enhancement of the quality factors of periodic island modes by up to 200 times.Strong and weak coupling between modes of very different origins occurs when the space curvature brings them into resonance,leading to fine tailoring of the cavity photon energy and lifetime and the observation of non-Hermitian exceptional point(EP).At large space curvatures,the role of the WGMs is replaced by high-Q periodic modes protected by the high stability of island-like light trajectory.Our work demonstrates interesting physical mechanisms at the crosspoint of optical chaotic dynamics,non-Hermitian physics,and geodesic optical devices,and would initiate the novel area of geodesic microcavity photonics. | Yongsheng Wang Yuhao Ren Xiaoxuan Luo Bo Li Zaoyu Chen Zhenzhi Liu Fu Liu Yin Cai Yanpeng Zhang Jin Liu Feng Li | 2022 | Light(Science & Applications)2022，11，11： | 1 |
| 5 | Scalable synthesis of macroscopic porous carbon sheet anode for potassium-ion capacitor显示文摘Carbon materials hold the great promise for application in energy storage devices owing to their low cost, high thermal/chemical stability, and high electrical conductivity. However, it remains challenging to synthesize high-performance carbon electrodes in a simple, scalable and sustainable way. Here, we report a facile method for scalable synthesis of porous carbon anode by using cheap and easily accessible zeolitic imidazolate framework-8 as a template and polyvinylpyrrolidone as an additional carbon source. The obtained porous carbon shows the macroscopic sheet-like morphology, which has the highly disordered structure, expanded interlayer spacing, abundant pore structure, and nitrogen doping properties. This porous carbon anode is demonstrated to have the excellent K^(+) charge storage properties in specific capacity, rate capability, and cycling stability. A potassium-ion capacitor assembled by using this porous carbon as the anode, delivers a maximum energy density of 85.12 Wh/kg and power density of 11860 W/kg as well as long cycle life exceeding 3000 cycles. This represents a critical advance in the design of low cost and scalable carbon material for applications in energy storage devices. | Yuying Qin Yuhao Xie Han Zhao Chunyan Zhu Tong Li Shuxian Zhang Rutao Wang Yuanchang Shi Longwei Yin | 2022 | Chinese Chemical Letters2022，33，3： | 1 |
| 6 | Remediation of Cu and As contaminated water and soil utilizing biochar supported layered double hydroxide:Mechanisms and soil environment altering显示文摘Preparing materials for simultaneous remediation of anionic and cationic heavy metals contamination has always been the focus of research. Herein a biochar supported FeMnMg layered double hydroxide(LDH) composites(LB) for simultaneous remediation of copper and arsenic contamination in water and soil has been assembled by a facile co-precipitation approach. Both adsorption isotherm and kinetics studies of heavy metals removal by LB were applied to look into the adsorption performance of adsorbents in water. Moreover, the adsorption mechanisms of Cu and As by LB were investigated, showing that Cu in aqueous solution was removed by the isomorphic substitution, precipitation and electrostatic adsorption while As was removed by complexation. In addition, the availability of Cu and As in the soil incubation experiments was reduced by 35.54%–63.00% and 8.39%–29.04%, respectively by using LB. Meanwhile, the addition of LB increased the activities of urease and sucrase by 93.78%–374.35% and 84.35%–520.04%, respectively, of which 1% of the dosage was the best. A phenomenon was found that the richness and structure of microbial community became vigorous within 1% dosage of LB, which indirectly enhanced the passivation and stabilization of heavy metals. These results indicated that the soil environment was significantly improved by LB. This research demonstrates that LB would be an imaginably forceful material for the remediation of anionic and cationic heavy metals in contaminated water and soil. | Pengling Shao Hua Yin Yingchao Li Yuhao Cai Caiya Yan Yibo Yuan Zhi Dang | 2023 | Journal of Environmental Sciences2023，，4： | 1 |
| 7 | Effects of Combined Stress from Salt and Herbicide on Microbial Remediation of Soil Contaminated by n-Hexadecane and Phenanthrene显示文摘In this study,physicochemical,cluster,and high-throughput sequencing analyses were used to investigate the joint effects of salt and herbicide(glyphosate)stress factors on the microbial remediation of soil contaminated by n-hexadecane and phenanthrene.Based on the soil’s physical and chemical properties,differences in microbial quantity and enzyme activities were analyzed among the samples,and how that influenced distribution of soil community structure was focused upon.After 120 days of indoor simulated remediation,the cumulative degradation rate of n-hexadecane decreased by 94.92%(blank control),96.96%(low concentration salt and glyphosate stress group),65.07%(high concentration salt and glyphosate stress group),while that of phenanthrene decreased by 87.33%(blank control),86.25%(low concentration salt and glyphosate stress group),58.45%(high concentration salt and glyphosate stress group).The combined stress of salt and herbicides was capable of lowering the reduction efficiency of organic matter,total nitrogen,and total phosphorus,and also restricting the growth of microorganisms and enzyme activities.Cluster analysis results indicated that the non-stress group was similar to the low-concentration compound stress group during different remedial period,whereas both of those differed starkly from the high-concentration compound stress group.High-throughput sequencing revealed that the dominant soil bacteria phyla shifted from Firmicutes to Actinobacteria within 120 days of remediation. | Liu Bingkun Zuo Shuai Wang Ruirui Dong Kangning Zhang Xiuxia Li Ruyue Hao Boyu Li Jing Yin Linghao Bai Yuhao Song Jiayu Gu Yingying Sun Juan | 2022 | China Petroleum Processing & Petrochemical Technology2022，24，2： | 0 |

| 9 | The paradoxical roles of miR-4295 in human cancer:Implications in pathogenesis and personalized medicine显示文摘MiR-4295,located on chromosome 10q25.2,is a unique miRNA with a wide range of biological functions.miR-4295 is widely expressed in vivo,participating in the biological processes of multiple cancers.Although miR-4295 is dysregulated in various cancers,it has also been found to have the function of inhibiting cancer.At the same time,the expression of miR-4295 is related to prognosis and can be affected by numerous factors connecting to the therapeutic effects of various drugs.This article is to better summarize the role of miR-4295 in cancer and review the potential diagnostic,prognostic,and therapeutic value of miR-4295,which may provide insight into subsequent research. | Yin Li Yihan Zhang Yuhao Zou Shiwei Duan | 2022 | Genes & Diseases2022，9，3： | 0 |
| 10 | Effect of Nano Silver Modification on the Dielectric Properties of Ag@TiO_(2)/PVDF Composites显示文摘To get a dielectric material with a high dielectric permittivity and suppressed dielectric loss,nano-Ag with a particle size of 20 nm and Ag@TiO_(2)core-shell particles with diameters of approximately 70-120 nm were embedded in polyvinylidene fluoride(PVDF)to fabricate nano-Ag/Ag@TiO_(2)/PVDF composites.After being modified by nano-Ag with 3 vol%optimal amount,the relative permittivity(ε_r)at 100 Hz of 50 vol%Ag@TiO_(2)/PVDF composites was 61,and the dielectric loss can be suppressed to 0.04,almost 96.4%lower than that of unmodified composites,and a higher frequency stability of bothε_r and loss has also been found.The underlying mechanism of the reduced loss was attributed to Maxwell-Wagner polarization and the Coulomb blockade effect caused by the introduction of a small amount of nano-Ag,which will block the movement of electrons between metal nanoparticles and composites.The space charge polarization and conductance loss are weakened at lower and higher Ag@TiO_(2)filling ratios,respectively,thus leading to a very low loss of the composites. | 戴金航 MENG Shunliang YANG Chuntian Lv Wenzhong CHEN Xizi YIN Yuhao 梁飞 | 2021 | Journal of Wuhan University of Technology(Materials Science)2021，36，3： | 0 |
| 11 | Spacecraft potential variations of the Swarm satellites at low Earth orbital altitudes显示文摘In this study, we provide the first detailed analysis of variations in the spacecraft potential (Vs) of the three Swarm satellites, which are flying at about 400-500 km. Unlike previous studies that have investigated extreme charging events, usually with spacecraft potentials as negative as −100 V, this study is focused on variations of Swarm Vs readings, which fall within a few negative volts. The Swarm observations show that spacecraft at low Earth orbital (LEO) altitudes are charged only slightly negatively, varying between −7 V and 0 V, with the majority of recorded potentials at these altitudes clustering close to −2 V. However, a second peak of Vs data is found at −5.5 V, though the event numbers for these more-negative observations are less, by an order of magnitude, than for incidents near the −2 V peak. These two distinct Vs peaks suggest two different causes. We have thus divided the Swarm spacecraft Vs data into two categories: less-negatively charged (−5 < Vs < 0 V) and more-negatively-charged (−6.5 < Vs < −5 V). These two Vs categories exhibit different spatial and temporal distributions. The Vs observations in the first category remain relatively closer to 0 V above the magnetic equator, but become much more negative at low and middle latitudes on the day side;at high latitudes, these first-category Vs readings are relatively more-negative during local summer. Second-category Vs events cluster into two bands at the middle latitudes (between ±20°-50° magnetic latitude), but with slightly more negative readings at the South Atlantic Anomaly (SAA) region;at high latitudes, these rarer but more-negative second-category Vs events exhibit relatively more-negative values during local winter, which is opposite to the seasonal pattern seen in the first category. By comparing Vs data to the distributions of background plasma density at Swarm altitudes, we find for the first category that more-negative Vs readings are recorded at regions with higher background plasma density, while for the second category the more-negative Vs data are observed at regions with lower background plasma density. This can be explained as follows: the electron and ion fluxes incident on Swarm surface, whose differences determine the potential of Swarm, are dominated by the background “cold” plasma (due to ionization) and “hot” plasma (due to precipitated particles from magnetosphere) for the two Vs categories, respectively. | HaiCheng Jiang Chao Xiong Fan Yin YuHao Zheng ZiYuan Zhu Rui Yan Yi Wen Liu | 2023 | Earth and Planetary Physics2023，7，4： | 0 |
| 12 | Design of a Microwave Filter Based on a Novel Negative Coupling Structure with Conical Through-Hole显示文摘This article introduces the design theory of ceramic waveguide filter and proposes a new type of negative coupling structure with a conical throughhole,which has fine-adjustment of negative coupling without significantly increasing the insertion loss of the filter.Based on this,the article proposes an eightcavity ceramic waveguide filter design for 5G base stations.It also presents a detailed discussion on the influence of the cross-coupling slot lengths L2 and L4 on the transmission zeros positions during the filter optimization process and the relevant change rules.For the proposed optimized filter,the observed performance indicators include the center frequency of 3.5 GHz,working bandwidth of 200 MHz,an insertion loss of≤2.0 dB,return loss of≥19 dB,and out-of-band nearend suppression and out-of-band far-end suppression of≥39 dB and≥63 dB,respectively.The test performance results obtained for the sample,with structural parameters as per the simulation model,were in good agreement with the simulation results. | Shunliang Meng Fei Liang Wenzhong Lu Zihang Lin Yuhao Yin Rong Zhang | 2022 | China Communications2022，19，2： | 0 |
| 13 | Recent advances in photothermal effects for hydrogen evolution显示文摘Photothermal effect has been widely employed in the H2 evolution process at the advantage of using clean energy sources to produce another one of higher benefits.The solar-to-heat conversion have various forms and heat can facilitate reactions in a variety of dimensions.Hence,summarizing the sources and destinations of heat is important for constructing hydrogen production systems of higher efficiency.This view mainly focuses on the recent state-of-art progress of hydrogen evolution reaction(HER)based on photothermal effect.First,we introduce the main pathways of photothermal conversions applied in H2 evolution.Then,the functions of the photothermal effect are clearly summarized.Furthermore,we go beyond the catalytic reaction and introduce a method to improve the catalytic system by changing the catalytic bulk phase through thermal means.In the end,we sort out the challenges and outlook to offer some noble insights for this promising area. | Pengcheng Fan Yuhao He Junan Pan Ning Sun Qiyu Zhang Chen Gu Kang Chen Weinan Yin Longlu Wang | 2024 | Chinese Chemical Letters2024，35，1： | 0 |
| 14 | Targeting UBE2C for degradation by bioPROTACs based on bacterial E3 ligase显示文摘UBE2C(Ubiquitin conjugating enzyme E2 C), a key regulator of cell cycle progression, is a promising target for discovery of antitumor agents. However, it is challenging to develop inhibitors of UBE2C owing to its lack of “druggable” pockets. Bio PROTACs(biological proteolysis targeting chimeras) are a kind of protein-based degraders by fusing an adaptor to a subunit of E3 ligase for ubiquitination and subsequent proteasome-dependent degradation of target protein. We report herein the design and biological evaluation of a UBE2C-targeting bio PROTAC based on the NEL(novel E3 ligase) domain of bacterial E3 ligase Ipa H9.8 and the UBE2C-binding WHB(winged-helix B) domain of APC_(2)(anaphase promoting complex subunit 2). The in vitro ubiquitination test and Mass Spectrometry analysis showed that the bio PROTAC could transfer ubiquitin to surface exposed lysines on UBE2C and catalyzed the formation of polyubiquitin chains. In addition, the transient co-expression experiment showed that the bio PROTAC could promote proteasomal degradation of heterologous UBE2C and rescue its downstream substrates in mammalian cells. | Jinpeng Wang Min Zhang Susheng Liu Zhipeng He Rui Wang Minchan Liang Yuhao An Chenran Jiang Chunli Song Zigong Ning Feng Yin Hao Huang Zigang Li Yuxin Ye | 2023 | Chinese Chemical Letters2023，34，4： | 0 |
