| 2 | Intermetallic Cu_(5)Zr Clusters Anchored on Hierarchical Nanoporous Copper as Efficient Catalysts for Hydrogen Evolution Reaction显示文摘Designing highly active and robust platinum-free electrocatalysts for hydrogen evolution reaction is vital for large-scale and efficient production of hydrogen through electrochemical water splitting.Here,we report nonprecious intermetallic Cu_(5)Zr clusters that are in situ anchored on hierarchical nanoporous copper(NP Cu/Cu_(5)Zr)for efficient hydrogen evolution in alkaline medium.By virtue of hydroxygenated zirconium atoms activating their nearby Cu-Cu bridge sites with appropriate hydrogenbinding energy,the Cu_(5)Zr clusters have a high electrocatalytic activity toward the hydrogen evolution reaction.Associated with unique architecture featured with steady and bicontinuous nanoporous copper skeleton that facilitates electron transfer and electrolyte accessibility,the self-supported monolithic NP Cu/Cu_(5)Zr electrodes boost violent hydrogen gas release,realizing ultrahigh current density of 500mAcm^(-2) at a low potential of-280mV versus reversible hydrogen electrode,with exceptional stability in 1M KOH solution.The electrochemical properties outperform those of state-of-the-art nonprecious metal electrocatalysts and make them promising candidates as electrodes in water splitting devices. | Hang Shi Yi-Tong Zhou Rui-Qi Yao Wu-Bin Wan Qing-Hua Zhang Lin Gu Zi Wen Xing-You Lang Qing Jiang | 2020 | Research2020，，1： | 4 |
| 3 | Epidemiological trends of urinary tract infections,urolithiasis and benign prostatic hyperplasia in 203 countries and territories from 1990 to 2019显示文摘Background:Urinary tract infections(UTI),urolithiasis,and benign prostatic hyperplasia(BPH)are three of the most common nonmalignant conditions in urology.However,there is still a lack of comprehensive and updated epidemiological data.This study aimed to investigate the disease burden of UTI,urolithiasis,and BPH in 203 countries and territories from 1990 to 2019.Methods:Data were extracted from the Global Burden of Disease 2019,including incident cases,deaths,disabilityadjusted life-years(DALYs)and corresponding age-standardized rate(ASR)from 1990 to 2019.Estimated annual percentage changes(EAPC)were calculated to evaluate the trends of ASR.The associations between disease burden and social development degrees were analyzed using a sociodemographic index(SDI).Results:Compared with 1990,the incident cases of UTI,urolithiasis,and BPH increased by 60.40%,48.57%,and 105.70%in 2019,respectively.The age-standardized incidence rate(ASIR)of UTI increased(EAPC=0.08),while urolithiasis(EAPC=–0.83)and BPH(EAPC=–0.03)decreased from 1990 to 2019.In 2019,the age-standardized mortality rate(ASMR)of UTI and urolithiasis were 3.13/100,000 and 0.17/100,000,respectively.BPH had the largest increase(110.56%)in DALYs in the past three decades,followed by UTI(68.89%)and urolithiasis(16.95%).The burden of UTI was mainly concentrated in South Asia and Tropical Latin America,while the burden of urolithiasis and BPH was recorded in Asia and Eastern Europe.Moreover,the ASIR and SDI of urolithiasis in high-SDI regions from 1990to 2019 were negatively correlated,while the opposite trend was seen in low-SDI regions.In 2019,the ASIR of UTI in females was 3.59 times that of males,while the ASIR of urolithiasis in males was 1.96 times higher than that in females.The incidence was highest in the 30–34,55–59,and 65–69 age groups among the UTI,urolithiasis,and BPH groups,respectively.Conclusions:Over the past three decades,the disease burden has increased for UTI but decreased for urolithiasis and BPH.The allocation of medical resources should be based more on the epidemiological characteristics and geographical distribution of diseases. | Cong Zhu Dan-Qi Wang Hao Zi Qiao Huang Jia-Min Gu Lu-Yao Li Xing-Pei Guo Fei Li Cheng Fang Xiao-Dong Li Xian-Tao Zeng | 2022 | Military Medical Research2022，9，4： | 4 |
| 4 | One-step generation of zebrafish carrying a conditional knockoutknockin visible switch via CRISPR/Cas9-mediated intron targeting显示文摘The zebrafish has become a popular vertebrate animal model in biomedical research.However,it is still challenging to make conditional gene knockout(CKO)models in zebrafish due to the low efficiency of homologous recombination(HR).Here we report an efficient non-HR-based method for generating zebrafish carrying a CKO and knockin(KI)switch(zCKOIS)coupled with dual-color fluorescent reporters.Using this strategy,we generated hey2^zCKOIS which served as a hey2 KI reporter with EGFP expression.Upon Cre induction in targeted cells,the hey2^zCKOIS was switched to a non-functional CKO allele hey2^zCKOIS-inv associated with Tag RFP expression,enabling visualization of the CKO alleles.Thus,simplification of the design,and the visibility and combination of both CKO and KI alleles make our z CKOIS strategy an applicable CKO approach for zebrafish. | Jia Li Hong-Yu Li Shan-Ye Gu Hua-Xing Zi Lai Jiang Jiu-Lin Du | 2020 | Science China(Life Sciences)2020，63，1： | 2 |
| 5 | UBE3A alleviates isoproterenol-induced cardiac hypertrophy through the inhibition of the TLR4/MMP-9 signaling pathway显示文摘Cardiac hypertrophy is considered to be a leading factor in heart function-related deaths.In this study,we explored the potential mechanism underlying cardiac hypertrophy induced by isoproterenol.Our results showed that isoproterenol induced cardiac hypertrophy in AC16 cells,as reflected by the increased cell surface area and increased hypertrophic markers,which was accompanied by increased ubiquitin-protein ligase E3a(UBE3A)expression.Moreover,UBE3A knockdown by siRNAs accelerated cardiac hypertrophy,suggesting that increased UBE3A expres sion induced by isoproterenol might be a protective response and UBE3A might be a protective factor against cardiac hypertrophy.Our study also revealed that UBE3A knockdown increased the protein expression of the TLR4/MMP-9 pathway that has been shown to be associated with cardiac hypertrophy,which suggested that UBE3A-mediated protection is likely to be associated with the blockade of the TLR4/MMP-9 signaling pathway.UBE3A might be thus a potential target gene for the treatment of cardiac hypertrophy. | Yanfei Li Linlin Ma Sijie Gu Jiewen Tian Yilin Cao Zi Jin Jingyi Chen Bingbing Gu Jiayin Tu Zhixiao Wang Xinming Li Zhongping Ning Yueling Jin | 2020 | Acta Biochimica et Biophysica Sinica2020，52，1： | 1 |
| 6 | The Synthesis and Characterization of High Molecular Weight Poly(phenylene sulfide/ether)显示文摘Poly(phenylene sulfide/ether) (PPSE) was synthesized from 4,4′-dihydroxydiphenyl sulfide and 4,4′-dichlorodiphenyl sulfide in solution by nucleophilic substitution reaction. The resulting polymer was characterized by viscosity measurement, elemental analysis, FT-IR, 1H NMR, X-ray diffraction and thermal analysis. The results showed that the viscosities of the resulting polymer were above 0.68 dL/g, and the linear chain structure of product was confirmed. PPSE had the same reflex indices as poly(p-phenylene sulfide), an orthorhombic crystalline with unit cell a=0.853, b=0.562, c=1.026nm. The melting temperature, glass transition temperature and initial decomposition temperature were found to be 228℃, 85℃ and 325℃, respectively. The product was soluble in common organic solvents such as NMP, N, N′-dimethylformamide, N, N′-dimethylacetamide and 1,2–dichloroethane. | Ai Qun GU Mei Ju XIE Zi Li YU | 2006 | Chinese Chemical Letters2006，17，10： | 1 |

| 11 | Structural and functional characteristics of microbiota in oropharynx of sub-healthy children with gastrointestinal heat retention syndrome differentiated by traditional Chinese medicine显示文摘Objective:To explore the structural and functional characteristics of microbiota in oropharynx of subhealthy children with gastrointestinal heat retention syndrome(GHRS)differentiated by traditional Chinese medicine,and screen the biometric operational taxonomic units(OTUs)to assist the clinical diagnosis.Methods:We recruited children according to the“GHRS diagnostic scale”,collected their oropharyngeal swabs,and sequenced the 16 SrDNA V4 region.We described the bacterial structure with alpha-indexes,beta-distances,and relative abundances;moreover,we screened the differential genera/OTUs with Wilcoxon rank-sum test,Metagenome Seq analysis,and linear discriminant analysis effect size(LEf Se)analysis,in which biometric OTUs were selected to construct the receiver operating characteristic curve to verify the diagnostic value.The bacterial function was predicted with Kyoto Encyclopedia of Genes and Genomes pathways according to 16S rDNA gene by using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States.Results:The study population was composed of 10 children with GHRS and 10 healthy control children.GHRS children were more likely to overeat(gluttony,P=.033).Alpha-indexes,such as Sobs,abundancebased coverage estimator,Bootstrap,and Qstat,were significantly higher in the GHRS group,while betadistances did not exhibit any significant intergroup differences.There were 9 differently distributed nonpredominant genera between the groups in Wilcoxon rank-sum test,as well as 13 non-predominant genera in Metagenome Seq analysis and 3 non-predominant OTUs in LEfSe analysis.OTU44 and OTU196 were used to construct the receiver operating characteristic curve,and the area under curve was 0.92.Predicted functions showed that pathways related to oxidative phosphorylation and carbon metabolism were enriched in healthy control samples,while the pathway related to renin secretion was remarkably enriched in GHRS samples.Conclusion:Unique oropharyngeal microbial structure and function were identified in GHRS children.OTU44 and OTU196 were specific OTUs,which could be used as biomarkers of GHRS to assist clinical diagnosis. | Jianhua Zhen He Yu Xiaofei Li Fei Dong Zi'an Zheng Xueyan Ma Yuxiang Wan Tiegang Liu Lu Fan Xiaohong Gu | 2022 | Journal of Traditional Chinese Medical Sciences2022，9，3： | 1 |

| 13 | Simulation and visualization experiment of manganese ion diffusion and damage to gel in a porous media-gel system显示文摘A new visualization method for studying the damage to gel structure caused by high salinity ions is explored by using the characteristics of suppression image signal of Mn^(2+) and nuclear magnetic resonance(NMR) imaging technique. The diffusion and distribution characteristics of Mn^(2+) in porous media-gel system were studied based on manganese chloride static diffusion and gel flooding experiments, and the gel's nuclear magnetic image and displacement pressure were tested. The results show that the diffusion of Mn^(2+)conforms to the Fick diffusion law in porous media-gel system, and the diffusion speed of Mn^(2+) increases and the area of gel image decreases gradually with the increase of concentration, and the image of gel decreases faster and the pressure drop of water drive is larger in flooding experiment of manganese chloride with higher concentration. Reaction-diffusion model with the reaction of Mn^(2+) with gel was established to study the concentration distribution characteristics of Mn^(2+). The model is validated by comparing the results with magnetic resonance imaging(MRI) experiments and the diffusion coefficient of Mn^(2+) equals 1.6 mm^2/h, and the minimum concentration of Mn^(2+) to impact gel NMR image signals is 2.5 g/L. The above results show that the diffusion of Mn^(2+) into the gel in the rock core inhibits the imaging signal of the gel and damages its strength, and the greater the concentration is, the greater the influence. Increase of adsorption amount of gel and reaction rate, reduction of diffusion time, and addition of ion adsorption isolator all can reduce the impact of Mn^(2+) on the gel. | GU Chunyuan QIN Rongsheng DI Qinfeng JIANG Fan LIU Zi'ang CHEN Huijuan | 2019 | Petroleum Exploration and Development2019，46，2： | 0 |

| 15 | Systemic and single cell level responses to 1 nm size biomaterials demonstrate distinct biological effects revealed by multi-omics atlas显示文摘Although ultra-small nanoclusters(USNCs,<2 nm)have immense application capabilities in biomedicine,the investigation on body-wide organ responses towards USNCs is scant.Here,applying a novel strategy of single-cell mass cytometry combined with Nano Genome Atlas of multi-tissues,we systematically evaluate the interactions between the host and calcium phosphate(CaP)USNCs at the organism level.Combining single-cell mass cytometry,and magnetic luminex assay results,we identify dynamic immune responses to CaP USNCs at the single cell resolution.The innate immune is initially activated and followed by adaptive immune activation,as evidenced by dynamic immune cells proportions.Furthermore,using Nano Genome Atlas of multi-tissues,we uncover CaP USNCs induce stronger activation of the immune responses in the cartilage and subchondral bone among the five local tissues while promote metabolic activities in the liver and kidney.Moreover,based on the immunological response profiles,histological evaluation of major organs and local tissue,and a body-wide transcriptomics,we demonstrate that CaP USNCs are not more hazardous than the Food and Drug Administration-approved CaP nanoparticles after 14 days of injection.Our findings provide valuable information on the future clinical applications of USNCs and introduce an innovative strategy to decipher the whole body response to implants. | Tao Zhang Tingyun Lei Ruojin Yan Bo Zhou Chunmei Fan Yanyan Zhao Shasha Yao Haihua Pan Yangwu Chen Bingbing Wu Yuwei Yang Lijuan Hu Shen Gu Xiaoyi Chen Fangyuan Bao Yu Li Hanqi Xie Ruikang Tang Xiao Chen Zi Yin | 2022 | Bioactive Materials2022，7，12： | 0 |
| 16 | Measurement of Br(n,γ)cross sections up to stellar s-process temperatures at the CSNS Back‑n显示文摘The neutron capture cross sections(n,γ)of bromine were obtained using the time-of-flight technique at the Back-n facility of the China Spallation Neutron Source.Promptγ-rays originating from neutron-induced capture events were detected using four C_(6)D_(6) detectors.The pulse-height weighting technique and double-bunch unfolding method based on Bayesian theory were used in the data analysis.Background deductions,normalization,and corrections were carefully considered to obtain reliable measurement results.The multilevel R-matrix Bayesian code SAMMY was used to extract the resonance parameters in the resolved resonance region(RRR).The average cross sections in the unresolved resonance region(URR)were obtained from 10 to 400 keV.The experimental results were compared with data from several evaluated libraries and previous experi-ments in the RRR and URR.The TALYS code was used to describe the average cross sections in the URR.The astrophysical Maxwell average cross sections(MACSs)of ^(79,81)Br from kT=5 to 100 keV were calculated over a sufficiently wide range of neutron energies.At a thermal energy of kT=30 keV,the MACS value for ^(79)Br 682±68 mb was in good agreement with the KADoNiS v1.0 recommended value.By contrast,the value of 293±29 mb for ^(81)Br was substantially higher than that of the evaluated database and the KADoNiS v1.0 recommended value. | Gao‑Le Yang Zhen‑Dong An Wei Jiang Xian‑Kai Li Wei‑Wei Qiu Zheng‑Fa Liao Zi‑Yue Zhuang Xiao‑Ping Zhang Sheng‑Li Chen Chen‑Chen Guo Er‑Xi Xiao Xiao Fang Xin‑Xiang Li Xin‑Rong Hu Bing Jiang Jin‑Cheng Wang Jie Ren Wen Luo Zhi‑Chao Zhu Hao‑Yang Lan Zong‑Wei Cao Xu Ma Ying‑Du Liu Pu‑Sen Wang Yi Yang Ping Su Xian‑Gai Deng Wan‑Bing He Chun‑Wang Ma Yu‑Ting Wang Zhi‑Tao Dai Peng‑Qin He Ren‑Guang Tang Tao Zhou Jing Wang Han Yi Yue Zhang Yong‑Hao Chen Rui‑Rui Fan Ke‑Qing Gao Qiang Li Kang Sun Zhi‑Xin Tan Min‑Hao Gu Han‑Tao Jing Jing‑Yu Tang | 2023 | Nuclear Science and Techniques2023，34，11： | 0 |

| 20 | Engineering human spinal microphysiological systems to model opioid-induced tolerance显示文摘pioids are commonly used for treating chronic pain.However,with continued use,they may induce tolerance and/or hyperalgesia,which limits therapeutic efficacy.The human mechanisms of opioid-induced tolerance and hyperalgesia are significantly understudied,in part,because current models cannot fully recapitulate human pathology.Here,we engineered novel human spinal microphysiological systems(MPSs)integrated with plug-and-play neural activity sensing for modeling human nociception and opioid-induced tolerance.Each spinal MPS consists of a flattened human spinal cord organoid derived from human stem cells and a 3D printed organoid holder device for plug-and-play neural activity measurement.We found that the flattened organoid design of MPSs not only reduces hypoxia and necrosis in the organoids,but also promotes their neuron maturation,neural activity,and functional development.We further demonstrated that prolonged opioid exposure resulted in neurochemical correlates of opioid tolerance and hyperalgesia,as measured by altered neural activity,and downregulation ofμ-opioid receptor expression of human spinal MPSs.The MPSs are scalable,cost-effective,easy-to-use,and compatible with commonly-used well-plates,thus allowing plug-and-play measurements of neural activity.We believe the MPSs hold a promising translational potential for studying human pain etiology,screening new treatments,and validating novel therapeutics for human pain medicine. | Hongwei Cai Zheng Ao Chunhui Tian Zhuhao Wu Connor Kaurich Zi Chen Mingxia Gu Andrea G.Hohmann Ken Mackie Feng Guo | 2023 | Bioactive Materials2023，，4： | 0 |
