| 1 | New generation of multi-scale NWP system (GRAPES):general scientific design显示文摘A new generation of numerical prediction system GRAPES (a short form of Global/Regional Assimilation and PrEdiction System) was set up in China Meteorological Administration (CMA). This paper focuses on the scientific design and preliminary results of the numerical prediction model in GRAPES, including basic idea and strategy of the general scientific design, multi-scale dynamic core, physical package configuration, architecture and parallelization of the codes. A series of numerical experiments using the real data with horizontal resolutions from 10 to 280 km and idealized experiments with very high resolution up to 100 m are conducted, giving encouraging results supporting the multi-scale application of GRAPES. The results of operational implementation of GRAPES model in some NWP centers are also presented with stress at evaluations of the capability to predict the main features of precipitation in China. Finally the issues to be dealt with for further development are discussed. | CHEN DeHui XUE JiShan YANG XueSheng ZHANG HongLiang SHEN XueShun HU JiangLin WANG Yu JI LiRen CHEN JiaBin | 2008 | Chinese Science Bulletin2008,53,22: | 70 |
| 2 | HIF-1α-induced expression of m6A reader YTHDF1 drives hypoxia-induced autophagy and malignancy of hepatocellular carcinoma by promoting ATG2A and ATG14 translation显示文摘N6-methyladenosine(m6A),and its reader protein YTHDF1,play a pivotal role in human tumorigenesis by affecting nearly everystage of RNA metabolism.Autophagy activation is one of the ways by which cancer cells survive hypoxia.However,the possibleinvolvement of m6A modification of mRNA in hypoxia-induced autophagy was unexplored in human hepatocellular carcinoma(HCO).In this study,specific variations in YTHDF1 expression were detected in YTHDF1-overexpressing,knockout,and-knockdownHCC cells,HCC organoids,and HCC patient-derived xenograft(PDX)murine models.YTHDF1 expression and hypoxia inducedautophagy were significantly correlated in vitro;signifhcant overexpression of YTHDF1 in HCC tissues was associated with poorprognosis,Multivariate cox regression analysis identihed YTHDF1 expression as an independent prognostic factor in patients withHCC.Multiple HC models conhrmed that YTHDF1 deficiency inhibited HCC autophagy,growth,and metastasis.Luciferase reporterassays and chromatin immunoprecipitation demonstrated that HlIF-1a regulated YTHDF1 transcription by directly binding to itspromoter region under hypoxia.The results of methylated RNA immunoprecipitation sequencing,proteomics,and polysomeprofling indicated that YTHDF1 contibuted to the translation of autophagy-related genes ATG2A and ATG14 by binding to m6A-modifhed ATG2A and ATG14 mRNA,thus facilitating autophagy and autophagy-related malignancy of HCC.Taken together,HlE-1d-induced YTHDF1 expression was associated with hypoxia-induced autophagy and autophagy-related HCC progression via promoting translation of autophagy-related genes ATG2A and ATG14 in a m6A-dependent manner.Our fndings suggest thatYTHDF1 is a potential prognostic biomarker and therapeutic target for patients with HCC. | Qing Li Yong Ni Liren Zhang Runqiu Jiang Jing Xu Hong Yang Yuanchang Hu Jiannan Qiu Liyong Pu Jinhai Tang Xuehao Wang | 2021 | Signal Transduction and Targeted Therapy2021,6,3: | 24 |
| 3 | Verification of GRAPES unified global and regional numerical weather prediction model dynamic core显示文摘During the past few years, most of the new developed numerical weather prediction models adopt the strategy of multi-scale technique. Therefore, China Meteorological Administration has devoted to developing a new generation of global and regional multi-scale model since 2003. In order to validate the performance of the GRAPES (Global and Regional Assimilation and PrEdiction System) model both for its scientific design and program coding, a suite of idealized tests has been proposed and conducted, which includes the density flow test, three-dimensional mountain wave and the cross-polar flow test. The density flow experiment indicates that the dynamic core has the ability to simulate the fine scale nonlinear flow structures and its transient features. While the three-dimensional mountain wave test shows that the model can reproduce the horizontal and vertical propagation of internal gravity waves quite well. Cross-polar flow test demonstrates the rationality of both for the semi-Lagrangian departure point calculation and the discretization of the model near the poles. The real case forecasts reveal that the model has the ability to predict the large-scale weather regimes in summer such as the subtropical high, and to capture the major synoptic patterns in the mid and high latitudes. | YANG XueSheng HU JiangLin CHEN DeHui ZHANG HongLiang SHEN XueShun CHEN JiaBin JI LiRen | 2008 | Chinese Science Bulletin2008,53,22: | 14 |

| 7 | Crimped nanofiber scaffold mimicking tendon-to-bone interface for fatty-infiltrated massive rotator cuff repair显示文摘Electrospun fibers,with proven ability to promote tissue regeneration,are widely being explored for rotator cuff repairing.However,without post treatment,the microstructure of the electrospun scaffold is vastly different from that of natural extracellular matrix(ECM).Moreover,during mechanical loading,the nanofibers slip that hampers the proliferation and differentiation of migrating stem cells.Here,electrospun nanofiber scaffolds,with crimped nanofibers and welded joints to biomimic the intricate natural microstructure of tendon-to-bone insertion,were prepared using poly(ester-urethane)urea and gelatin via electrospinning and double crosslinking by a multi-bonding network densification strategy.The crimped nanofiber scaffold(CNS)features bionic tensile stress and induces chondrogenic differentiation,laying credible basis for in vivo experimentation.After repairing a rabbit massive rotator cuff tear using a CNS for 3 months,the continuous translational tendon-to-bone interface was fully regenerated,and fatty infiltration was simultaneously inhibited.Instead of micro-CT,μCT was employed to visualize the integrity and intricateness of the three-dimensional microstructure of the CNS-induced-healed tendon-to-bone interface at an ultra-high resolution of less than 1μm.This study sheds light on the correlation between nanofiber post treatment and massive rotator cuff repair and provides a general strategy for crimped nanofiber preparation and tendon-to-bone interface imaging characterization. | Liren Wang Tonghe Zhu Yuhao Kang Jianguang Zhang Juan Du Haihan Gao Sihao Chen Jia Jiang Jinzhong Zhao | 2022 | Bioactive Materials2022,7,10: | 2 |

| 14 | Three-Year Consecutive Field Application of Erythromycin Fermentation Residue Following Hydrothermal Treatment:Cumulative Effect on Soil Antibiotic Resistance Genes显示文摘Fermentation-based antibiotic production results in abundant nutrient-rich fermentation residue with high potential for recycling,but the high antibiotic residual concentration restricts its usefulness(e.g.,in land application as organic fertilizer).In this study,an industrial-scale hydrothermal facility for the treatment of erythromycin fermentation residue(EFR)was investigated,and the potential risk of the long-term soil application of treated EFR promoting environmental antibiotic resistance development was evaluated.The treatment effectively removed bacteria and their DNA,and an erythromycin removal ratio of up to approximately 98%was achieved.The treated EFR was utilized as organic fertilizer for consecutive field applications from 2018 to 2020,with dosages ranging from 3750 to 15000 kg·hm^(-2),resulting in subinhibitory levels of erythromycin(ranging from 0.83-76.00μg·kg^(-1))in soils.Metagenomic shotgun sequencing was then used to characterize the antibiotic resistance genes(ARGs),mobile genetic elements(MGEs),and bacterial community composition of the soils.The soil ARG abundance and diversity did not respond to the treated EFR application in the first year,but gradually changed in the second and third year of application.The highest fold change in relative abundance of macrolide-lincosamide-streptogramin(MLS)and total ARGs were 12.59 and 2.75 times,compared with the control(CK;without application),respectively.The soil MGEs and taxonomic composition showed similar temporal trends to those of the ARGs,and appeared to assist in driving increasing ARG proliferation,as revealed by correlation analysis and structural equation models(SEMs).The relative abundance of particular erm resistance genes(RNA methyltransferase genes)increased significantly in the third year of treated EFR application.The close association of erm with MGEs suggested that horizontal gene transfer played a critical role in the observed erm gene enrichment.Metagenomic binning results demonstrated that the proliferation of mac genecarrying hosts was responsible for the increased abundance of mac genes(efflux pump genes).This study shows that sub-inhibitory levels of erythromycin in soils had a cumulative effect on soil ARGs over time and emphasizes the importance of long-term monitoring for assessing the risk of soil amendment with treated industrial waste. | Ziming Han Haodi Feng Xiao Luan Yunpeng Shen Liren Ren Liujie Deng D.G.Joakim Larsson Michael Gillings Yu Zhang Min Yang | 2022 | Engineering2022,8,8: | 1 |

| 17 | Mefatinib as first-line treatment of patients with advanced EGFR-mutant non-small-cell lung cancer:a phase Ib/II efficacy and biomarker study显示文摘EGFR inhibitors have revolutionized the treatment of advanced non-small-cell lung cancer(NSCLC).Mefatinib is a novel,bioavailable,second-generation,irreversible pan-EGFR inhibitor.This phase Ib/II open-label,single-arm,multi-center study investigated the efficacy,safety,biomarker,and resistance mechanisms of mefatinib in the first-line treatment of patients with advanced EGFR-mutant NSCLC.This study included 106 patients with EGFR-mutant stage IIIB-IV NSCLC who received first-line mefatinib at a daily dose of either 60 mg(n=51)or 80 mg(n=55).The primary endpoint was progression-free survival(PFS).Secondary endpoints were overall response rate(ORR),disease control rate(DCR),overall survival(OS),and safety.The cohort achieved an ORR of 84.9%and DCR of 97.2%.The median PFS was 15.4 months and the median OS was 31.6 months.Brain metastasis was detected in 29%of patients(n=31)at diagnosis and demonstrated an ORR of 87.1%,PFS of 12.8 months,and OS of 25.2 months.Adverse events primarily involved skin and gastrointestinal toxicities,which were well-tolerated and manageable.Analyses of mutation profiles were performed using targeted sequencing of plasma samples at baseline,first follow-up 6 weeks from starting mefatinib therapy(F1),and at progression.Patients with concurrent TP53 mutations had comparable PFS as wild-type TP53(14.0 vs 15.4 months;p=0.315).Furthermore,circulating tumor DNA clearance was associated with longer PFS(p=0.040)and OS(p=0.002).EGFR T790M was the predominant molecular mechanism of mefatinib resistance(42.1%,16/38).First-line mefatinib provides durable PFS and an acceptable toxicity profile in patients with advanced EGFR-mutant NSCLC. | Pingli Wang Yuping Li Dongqing Lv Lingge Yang Liren Ding Jianya Zhou Wei Hong Youfei Chen Dongqing Zhang Susu He Jianying Zhou Kai Wang | 2021 | Signal Transduction and Targeted Therapy2021,6,12: | 1 |
| 18 | Essential Features of Tectonic Movement Revealed by Crustal Vertical Deformations in the Mainland of China显示文摘Based on the precise reieveling data of more than 260,000 km carried out from 1950 to 1991 in the Chinese mainland,recent crustal vertical movement is studied.By means of some quantitative indices,such as the pattern of crustal vertical movement,the intensity of differential movement,the maximum gradient and its distribution,etc.,the properties of movements are analyzed on a large scale.The results suggest that all the properties have a profound tectonic background of their own and are closely related to the zoning and seismic activity of active subplates.The driving force for the movement comes mainly from the northward push of the India plate acting on the Eurasia plate.The effects of motions of the Pacific and Philippine Sea plates in the east are much less significant. | Huang Liren,Zhang Xingke1,and Ma QingFirst Land Deformation Monitoring Center,SSB,Tianjin 300180,China Seismological Bureau of Jilin Province,Changchun 130022,China | 1995 | Earthquake Research in China1995,9,4: | 1 |
| 19 | Canine ACL reconstruction with an injectable hydroxyapatite/collagen paste for accelerated healing of tendon-bone interface显示文摘Healing of an anterior cruciate ligament(ACL)autologous graft in a bone tunnel occurs through the formation of fibrovascular scar tissue,which is structurally and compositionally inferior to normal fibrocartilaginous insertion and thus may increase the reconstruction failure and the rate of failure recurrence.In this study,an injectable hydroxyapatite/type I collagen(HAp/Col I)paste was developed to construct a suitable local microenvironment to accelerate the healing of bone-tendon interface.Physicochemical characterization demonstrated that the HAp/Col I paste was injectable,uniform and stable.The in vitro cell culture illustrated that the paste could promote MC3T3-E1 cells proliferation and osteogenic expression.The results of a canine ACL reconstruction study showed that the reconstructive ACL had similar texture and color as the native ACL.The average width of the tunnel,total bone volume,bone volume/tissue volume and trabecular number acquired from micro-CT analysis suggested that the healing of tendon-bone interface in experimental group was better than that in control group.The biomechanical test showed the maximal loads in experimental group achieved approximately half of native ACL’s maximal load at 24 weeks.According to histological examination,Sharpey fibers could be observed as early as 12 weeks postoperatively while a typical four-layer transitional structure of insertion site was regenerated at 48 weeks in the experimental group.The injectable HAp/Col I paste provided a biomimetic scaffold and microenvironment for early cell attachment and proliferation,further osteogenic expression and extracellular matrix deposition,and in vivo structural and functional regeneration of the tendon-bone interface. | Qingsong Jiang Liren Wang Zhanhong Liu Jinlei Su Yajun Tang Peijie Tan Xiangdong Zhu Kai Zhang Xing Ma Jia Jiang Jinzhong Zhao Hai Lin Xingdong Zhang | 2023 | Bioactive Materials2023,,2: | 1 |
