| 1 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
| 2 | Chemical characterization of size-resolved aerosols in four seasons and hazy days in the megacity Beijing of China显示文摘Size-resolved aerosol samples were collected by MOUDI in four seasons in 2007 in Beijing. The PM10 and PM1.8mass concentrations were 166.0 ± 120.5 and 91.6 ± 69.7 μg/m^3, respectively,throughout the measurement, with seasonal variation: nearly two times higher in autumn than in summer and spring. Serious fine particle pollution occurred in winter with the PM1.8/PM10 ratio of 0.63, which was higher than other seasons. The size distribution of PM showed obvious seasonal and diurnal variation, with a smaller fine mode peak in spring and in the daytime. OM(organic matter = 1.6 × OC(organic carbon)) and SIA(secondary inorganic aerosol) were major components of fine particles, while OM, SIA and Ca_2+were major components in coarse particles. Moreover, secondary components, mainly SOA(secondary organic aerosol) and SIA,accounted for 46%–96% of each size bin in fine particles, which meant that secondary pollution existed all year. Sulfates and nitrates, primarily in the form of(NH_4)_2SO_4, NH_4NO_3, Ca SO_4, Na_2SO_4 and K_2SO_4, calculated by the model ISORROPIA II, were major components of the solid phase in fine particles. The PM concentration and size distribution were similar in the four seasons on non-haze days, while large differences occurred on haze days, which indicated seasonal variation of PM concentration and size distribution were dominated by haze days. The SIA concentrations and fractions of nearly all size bins were higher on haze days than on non-haze days, which was attributed to heterogeneous aqueous reactions on haze days in the four seasons. | Kang Sun Xingang Liu Jianwei Gu Yunpeng Li Yu Qu Junling An Jingli Wang Yuanhang Zhang Min Hu Fang Zhang | 2015 | Journal of Environmental Sciences2015，27，6： | 19 |
| 3 | Chemical characteristics of size-resolved aerosols in winter in Beijing显示文摘Size-resolved aerosols were continuously collected by a Nano Sampler for 13 days at an urban site in Beijing during winter 2012 to measure the chemical composition of ambient aerosol particles. Data collected by the Nano Sampler and an ACSM(Aerodyne Aerosol Chemical Speciation Monitor) were compared. Between the data sets,similar trends and strong correlations were observed,demonstrating the validity of the Nano Sampler. PM10 and PM2.5concentrations during the measurement were 150.5 ± 96.0 μg/m3(mean ± standard variation)and 106.9 ± 71.6 μg/m3,respectively. The PM2.5/PM10 ratio was 0.70 ± 0.10,indicating that PM2.5dominated PM10. The aerosol size distributions showed that three size bins of 0.5–1,1–2.5 and 2.5–10 μm contributed 21.8%,23.3% and 26.0% to the total mass concentration(TMC),respectively. OM(organic matter) and SIA(secondary ionic aerosol,mainly SO42-,NO3-and NH4+) were major components of PM2.5. Secondary compounds(SIA and secondary organic carbon) accounted for half of TMC(about 49.8%) in PM2.5,and suggested that secondary aerosols significantly contributed to the serious particulate matter pollution observed in winter. Coal burning,biomass combustion,vehicle emissions and SIA were found to be the main sources of PM2.5. Mass concentrations of water-soluble ions and undetected materials,as well as their fractions in TMC,strikingly increased with deteriorating particle pollution conditions,while OM and EC(elemental carbon) exhibited different variations,with mass concentrations slightly increasing but fractions in TMC decreasing. | Kang Sun Yu Qu Qiong Wu Tingting Han Jianwei Gu Jingjing Zhao Yele Sun Qi Jiang Ziqi Gao Min Hu Yuanhang Zhang Keding Lu Stephan Nordmann Yafang Cheng Li Hou Hui Ge Masami Furuuchi Mitsuhiko Hata Xingang Liu | 2014 | Journal of Environmental Sciences2014，26，8： | 9 |
| 4 | The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels. | Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu | 2022 | Science China(Life Sciences)2022，65，12： | 4 |
| 5 | How are MCPIP1 and cytokines mutually regulated in cancer-related immunity?显示文摘Cytokines are secreted by various cell types and act as critical mediators in many physiological processes,including immune response and tumor progression.Cytokines production is precisely and timely regulated by multiple mechanisms at different levels,ranging from transcriptional to post-transcriptional and posttranslational processes.Monocyte chemoattractant protein-1 induced protein 1(MCPIP1),a potent immunosuppressive protein,was first described as a transcription factor in monocytes treated with monocyte chemoattractant protein-1(MCP-1)and subsequently found to possess intrinsic RNase and deubiquitinase activities.MCPIP1 tightly regulates cytokines expression via various functions.Furthermore,cytokines such as interleukin 1 beta(IL-1B)and MCP-1 and inflammatory cytokines inducer lipopolysaccharide(LPS)strongly induce MCPIP1 expression.Mutually regulated MCPIP1 and cytokines form a complicated network in the tumor environment.In this review,we summarize how MCPIP1 and cytokines reciprocally interact and elucidate the effect of the network formed by these components in cancer-related immunity with aim of exploring potential clinical benefits of their mutual regulation. | Ruyi Xu Yi Li Yang Liu Jianwei Qu Wen Cao Enfan Zhang Jingsong He Zhen Cai | 2020 | Protein & Cell2020，11，12： | 2 |
| 6 | Genome assembly of the maize inbred line A188 provides a new reference genome for functional genomics显示文摘The current assembled maize genomes cannot represent the broad genetic diversity of maize germplasms.Acquiring more genome sequences is critical for constructing a pan-genome and elucidating the linkage between genotype and phenotype in maize.Here we describe the genome sequence and annotation of A188,a maize inbred line with high phenotypic variation relative to other lines,acquired by single-molecule sequencing and optical genome mapping.We assembled a 2210-Mb genome with a scaffold N50 size of 11.61 million bases(Mb),compared to 9.73 Mb for B73 and 10.2 Mb for Mo17.Based on the B73_Ref Gen_V4 genome,295 scaffolds(2084.35 Mb,94.30%of the final genome assembly)were anchored and oriented on ten chromosomes.Comparative analysis revealed that~30%of the predicted A188 genes showed large structural divergence from B73,Mo17,and W22 genomes,which causes high protein divergence and may lead to phenotypic variation among the four inbred lines.As a line with high embryonic callus(EC)induction capacity,A188 provides a convenient tool for elucidating the molecular mechanism underlying the formation of EC in maize.Combining our new A188 genome with previously reported QTL and RNA sequencing data revealed eight genes with large structural variation and two differentially expressed genes playing potential roles in maize EC induction. | Fei Ge Jingtao Qu Peng Liu Lang Pan Chaoying Zou Guangsheng Yuan Cong Yang Guangtang Pan Jianwei Huang Langlang Ma Yaou Shen | 2022 | The Crop Journal2022，10，1： | 2 |
| 7 | Theoretical and experimental study on seismic response control on top of Three-Gorges ship lift towers using magnetorheological intelligent isolation system and its key technique显示文摘A vertical ship lift under earthquake excitation may suffer from a whipping effect due to the sudden change of building lateral stiffness at the top of the ship lift towers.This paper proposes a roof magnetorheological(MR)intelligent isolation system to prevent the seismic whipping effect on machinery structures.Theoretically,the dynamic models of MR damper and the mechanical model of ship lift was established,the inverse neural network controlling algorithm was proposed and the fundamental semi-active control equation for the Three-Gorges ship lift where the MR intelligent isolation system was installed was deduced.Experimentally,the experimental model of the ship lift was given,the vibrating table experiment of the MR intelligent isolation system controlling the whipping effect was carried out and the results of the inverse neural network control strategy and passive isolation strategy were compared.In practical aspect,the large-scale MR damper(500 kN)and a sliding support with limited stiffness were designed and fabricated.It was proven that the MR intelligent isolation system with proper control strategy can greatly reduce the seismic whipping effect on the top workshop of the ship lift and be simple and effective enough to be applied to real engineering structures. | Weilian QU Jianwei TU | 2009 | Frontiers of Structural and Civil Engineering2009，3，1： | 2 |
| 8 | Biomarkers of aging显示文摘Aging biomarkers are a combination of biological parameters to(i)assess age-related changes,(ii)track the physiological aging process,and(iii)predict the transition into a pathological status.Although a broad spectrum of aging biomarkers has been developed,their potential uses and limitations remain poorly characterized.An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research:How old are we?Why do we get old?And how can we age slower?This review aims to address this need.Here,we summarize our current knowledge of biomarkers developed for cellular,organ,and organismal levels of aging,comprising six pillars:physiological characteristics,medical imaging,histological features,cellular alterations,molecular changes,and secretory factors.To fulfill all these requisites,we propose that aging biomarkers should qualify for being specific,systemic,and clinically relevant. | Aging Biomarker Consortium Hainan Bao Jiani Cao Mengting Chen Min Chen Wei Chen Xiao Chen Yanhao Chen Yu Chen Yutian Chen Zhiyang Chen Jagadish K Chhetri Yingjie Ding Junlin Feng Jun Guo Mengmeng Guo Chuting He Yujuan Jia Haiping Jiang Ying Jing Dingfeng Li Jiaming Li Jingyi Li Qinhao Liang Rui Liang Feng Liu Xiaoqian Liu Zuojun Liu Oscar Junhong Luo Jianwei Lv Jingyi Ma Kehang Mao Jiawei Nie Xinhua Qiao Xinpei Sun Xiaoqiang Tang Jianfang Wang Qiaoran Wang Siyuan Wang Xuan Wang Yaning Wang Yuhan Wang Rimo Wu Kai Xia Fu-Hui Xiao Lingyan Xu Yingying Xu Haoteng Yan Liang Yang Ruici Yang Yuanxin Yang Yilin Ying Le Zhang Weiwei Zhang Wenwan Zhang Xing Zhang Zhuo Zhang Min Zhou Rui Zhou Qingchen Zhu Zhengmao Zhu Feng Cao Zhongwei Cao Piu Chan Chang Chen Guobing Chen Hou-Zao Chen Jun Chen Weimin Ci Bi-Sen Ding Qiurong Ding Feng Gao Jing-Dong JHan Kai Huang Zhenyu Ju Qing-Peng Kong Ji Li Jian Li Xin Li Baohua Liu Feng Liu Lin Liu Qiang Liu Qiang Liu Xingguo Liu Yong Liu Xianghang Luo Shuai Ma Xinran Ma Zhiyong Mao Jing Nie Yaojin Peng Jing Qu Jie Ren Ruibao Ren Moshi Song Zhou Songyang Yi Eve Sun Yu Sun Mei Tian Shusen Wang Si Wang Xia Wang Xiaoning Wang Yan-Jiang Wang Yunfang Wang Catherine CL Wong Andy Peng Xiang Yichuan Xiao Zhengwei Xie Daichao Xu Jing Ye Rui Yue Cuntai Zhang Hongbo Zhang Liang Zhang Weiqi Zhang Yong Zhang Yun-Wu Zhang Zhuohua Zhang Tongbiao Zhao Yuzheng Zhao Dahai Zhu Weiguo Zou Gang Pei Guang-Hui Liu | 2023 | Science China(Life Sciences)2023，66，5： | 2 |

| 10 | A single-cell transcriptome atlas of the aging human and macaque retina显示文摘The human retina is a complex neural tissue that detects light and sends visual information to the brain.However,the molecular and cellular processes that underlie aging primate retina remain unclear.Here,we provide a comprehensive transcriptomic atlas based on 119520 single cells of the foveal and peripheral retina of humans and macaques covering different ages.The molecular features of retinal cells differed between the two species,suggesting distinct regional and species specializations of the human and macaque retinae.In addition,human retinal aging occurred in a region-and cell-type-specific manner.Aging of human retina exhibited a foveal to peripheral gradient.MYO9A-rods and a horizontal cell subtype were greatly reduced in aging retina,indicating their vulnerability to aging.Moreover,we generated a dataset showing the cell-type-and region-specific gene expression associated with 55 types of human retinal disease,which provides a foundation to understanding of the molecular and cellular mechanisms underlying human retinal diseases.Such datasets are valuable to understanding of the molecular characteristics of primate retina,as well as molecular regulation of aging progression and related diseases. | Wenyang Yi Yufeng Lu Suijuan Zhong Mei Zhang Le Sun Hao Dong Mengdi Wang Min Wei Haohuan Xie Hongqiang Qu Rongmei Peng Jing Hong Ziqin Yao Yunyun Tong Wei Wang Qiang Ma Zeyuan Liu Yuqian Ma Shouzhen Li Chonghai Yin Jianwei Liu Chao Ma Xiaoqun Wang Qian Wu Tian Xue | 2021 | National Science Review2021，8，4： | 1 |

| 14 | Oxidation of benzene to phenol with N_(2)O over a hierarchical Fe/ZSM-5 catalyst显示文摘Catalytic oxidation of benzene with N_(2)O to phenol over the hierarchical and microporous Fe/ZSM-5-based catalysts in a continuous fixedbed reactor was investigated.The spent catalyst was in-situ regenerated by an oxidative treatment using N_(2)O and in total 10 reaction-regeneration cycles were performed.A 100% N_(2)O conversion,93.3% phenol selectivity,and high initial phenol formation rate of 16.49±0.06mmol_(phenol gcatalyst)^(-1)h^(-1)at time on stream(TOS) of 5 min,and a good phenol productivity of 147.06 mmol_(phenol gcatalyst)^(-1)during catalyst lifetime of 1800 min were obtained on a fresh hierarchical Fe/ZSM-5-Hi2.8 catalyst.With the reaction-regeneration cycle,N_(2)O conversion is fully recovered within TOS of 3 h,moreover,the phenol productivity was decreased ca.2.2±0.8% after each cycle,leading to a total phenol productivity of ca.0.44 ton_(pheol kg_(catalyst)^(-1)estimated for 300 cycles.Catalyst characterizations imply that the coke is rapidly deposited on catalyst surface in the initial TOS of 3 h(0.28 mgc_(gcatalyst)^(-1)min^(-1)) and gradually becomes graphitic during the TOS of 30 h with a slow formation rate of 0.06 mgc g_(catalyst)^(-1)min^(-1).Among others(e.g.,the decrease of textural property and acidity),the nearly complete coverage of the active Fe-O-Al sites by coke accounts for the main catalyst deactivation.Besides these reversible deactivation characteristics related to coking,the irreversible catalyst deactivation is also observed with the reaction-regeneration cycle.The latter is reflected by a further decreased amount of the active Fe-O-Al sites,which agglomerate on catalyst surface with the cycle,likely associated with the hard coke residue that is not completely removed by the regeneration. | Cui Ouyang Jianwei Li Yaqi Qu Song Hong Songbo He | 2023 | Green Energy & Environment2023，8，4： | 0 |
| 15 | Caspase-1 and Gasdermin D Afford the Optimal Targets with Distinct Switching Strategies in NLRP1b Inflammasome-Induced Cell Death显示文摘Inflammasomes are essential complexes of innate immune system, which form the first line of host defense against pathogens. Mounting evidence accumulates that inflammasome signaling is highly correlated with coronavirus disease 2019 (COVID-19). However, there remains a significant gap in our understanding of the regulatory mechanism of inflammasome signaling. Combining mathematical modeling with experimental analysis of NLRP1b inflammasome signaling, we found that only the expression levels of caspase-1 and GSDMD have the potential to individually switch cell death modes. Reduction of caspase-1 or GSDMD switches cell death from pyroptosis to apoptosis. Caspase-1 and GSDMD present different thresholds and exert distinct pathway choices in switching death modes. Pyroptosis switches to apoptosis with an extremely low threshold level of caspase-1, but with a high threshold of GSDMD. Caspase-1-impaired cells employ ASC-caspase-8-dependent pathway for apoptosis, while GSDMD-impaired cells primarily utilize caspase-1-dependent pathway. Additionally, caspase-1 and GSDMD can severally ignite the cooccurrence of pyroptosis and apoptosis. Landscape topography unravels that the cooccurrence is dramatically different in caspase-1- and GSDMD-impaired cells. Besides pyroptosis state and apoptosis state, a potential new “coexisting” state in single cells is proposed when GSDMD acts as the driving force of the landscape. The “seesaw model” is therefore proposed, which can well describe the death states that are controlled by caspase-1 or GSDMD in single cells. Our study sheds new light on NLRP1b inflammasome signaling and uncovers the switching mechanisms among various death modes, providing potential clues to guide the development of more rational control strategies for diseases. | Xiang Li Peipei Zhang Zhiyong Yin Fei Xu Zhang-Hua Yang Jun Jin Jing Qu Zhilong Liu Hong Qi Chenggui Yao Jianwei Shuai | 2022 | Research2022，，4： | 0 |

| 17 | KCNH2 regulates the growth and metastasis of pancreatic cancer显示文摘Objective:Due to the characteristics of insidious onset and early metastasis of pancreatic cancer(PC),patients are often diag-nosed at an advanced stage and often delayed in completing surgical resection timely,resulting in poor prognosis.Therefore,this study aims to explore the expression of potassium voltage-gated channel subfamily H member 2(KCNH2)in PC and its relation-ship with clinicopathological parameters and the related mechanisms.Methods:GEPIA database and immunohistochemical staining were used to analyze the difference in KCNH2 expression be-tween PC and adjacent tissue in RNA and protein levels.Chi-squared test was used to evaluate the relationship between KCNH2 expression and clinicopathological features.The Cox regression model was used for multivariate analysis and univariate analysis.Histological diagnosis was performed according to World Health Organization(WHO)criteria to evaluate the relationship between KCNH2 expression and clinicopathological features.Results:KCNH2 expression was upregulated in PC compared with normal pancreatic tissue.In addition,the knockdown of KCNH2 inhibits PC cell proliferation,migration,invasion,and epithelial-mesenchymal transformation and promotes their apopto-sis.In addition,clinical data showed that the abnormal expression of KCNH2 in PC was related to the tumor stage.Patients with high expression of KCNH2 had a poor prognosis.Conclusions:KCNH2 is expected to be a novel targeted molecule in treating PC. | Jinghao Lei Qiang Wang Tengfei Qu Lichao Cha Hanxiang Zhan Jianwei Xu Shanglong Liu Lantian Tian Chuandong Sun Jingyu Cao Fabo Qiu Weidong Guo Bin Zhou | 2023 | Journal of Pancreatology2023，6，3： | 0 |
| 18 | Rapid inactivation of human respiratory RNA viruses by deep ultraviolet irradiation from light-emitting diodes on a high-temperatureannealed AlN/Sapphire template显示文摘Efficient and eco-friendly disinfection of air-borne human respiratory RNA viruses is pursued in both public environment and portable usage.The AlGaN-based deep ultraviolet(DUV)light-emission diode(LED)has high practical potentials because of its advantages of variable wavelength,rapid sterilization,environmental protection,and miniaturization.Therefore,whether the emission wavelength has effects on the disinfection as well as whether the device is feasible to sterilize various respiratory RNA viruses under portable conditions is crucial.Here,we fabricate AlGaN-based DUV LEDs with different wavelength on high-temperature-annealed(HTA)AlN/Sapphire templates and investigate the inactivation effects for several respiratory RNA viruses.The AlN/AlGaN superlattices are employed between the template and upper n-AlGaN to release the strong compressive stress(SCS),improving the crystal quality and interface roughness.DUV LEDs with the wavelength of 256,265,and 278 nm,corresponding to the light output power of 6.8,9.6,and 12.5 mW,are realized,among which the 256 nm-LED shows the most potent inactivation effect in human respiratory RNA viruses,including SARS-CoV-2,influenza A virus(IAV),and human parainfluenza virus(HPIV),at a similar light power density(LPD)of~0.8 mW/cm2 for 10 s.These results will contribute to the advanced DUV LED application of disinfecting viruses with high potency and broad spectrum in a portable and eco-friendly use. | Ke Jiang Simeng Liang Xiaojuan Sun Jianwei Ben Liang Qu Shanli Zhang Yang Chen Yucheng Zheng Ke Lan Dabing Li Ke Xu | 2023 | Opto-Electronic Advances2023，6，9： | 0 |
| 19 | Advances in electrode interface materials and modification technologies for brain-computer interfaces显示文摘Recent advances in neuroelectrode interface materials and modification technologies are reviewed. Brain-computer interface is the new method of human-computer interaction, which not only can realise the exchange of information between the human brain and external devices, but also provides a brand-new means for the diagnosis and treatment of brain-related diseases. The neural electrode interface part of brain-computer interface is an important area for electrical, optical and chemical signal transmission between brain tissue system and external electronic devices, which determines the performance of brain-computer interface. In order to solve the problems of insufficient flexibility, insufficient signal recognition ability and insufficient biocompatibility of traditional rigid electrodes, researchers have carried out extensive studies on the neuroelectrode interface in terms of materials and modification techniques. This paper introduces the biological reactions that occur in neuroelectrodes after implantation into brain tissue and the decisive role of the electrode interface for electrode function. Following this, the latest research progress on neuroelectrode materials and interface materials is reviewed from the aspects of neuroelectrode materials and modification technologies, firstly taking materials as a clue, and then focusing on the preparation process of neuroelectrode coatings and the design scheme of functionalised structures. | Yunke Jiao Miao Lei Jianwei Zhu Ronghang Chang Xue Qu | 2023 | Biomaterials Translational2023，4，4： | 0 |
