| 1 | First Human Infection Case of Monkey B Virus Identified in China,2021显示文摘Monkey B virus(BV),initially isolated in 1932,is currently designated as Macacine alphaherpesvirus 1 by the International Committee on Taxonomy of Viruses(1).BV is an alphaherpesvirus enzootic in macaques of the genus Macaca,normally transmitted horizontally via direct contact and exchange of bodily secretions,just like herpes simplex virus(HSV)in humans. | Wenling Wang Wenjie Qi Jingyuan Liu Haijun Du Li Zhao Yang Zheng Guoxing Wang Yang Pan Baoying Huang Zhaomin Feng Daitao Zhang Peng Yang Jun Han Quanyi Wang Wenjie Tan | 2021 | China CDC weekly2021，3，29： | 4 |
| 2 | Genomic characterization of SARS-CoV-2 identified in a reemerging COVID-19 outbreak in Beijing's Xinfadi market in 2020显示文摘After 56 days without coronavirus disease 2019(COVID-19)cases,reemergent cases were reported in Beijing,China on June 11,2020.Here,we report the genetic characteristics of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)sequenced from the clinical specimens of 4 human cases and 2 environmental samples.The nucleotide similarity among six SARS-CoV-2 genomes ranged from 99.98%to 99.99%.Compared with the reference strain of SARS-CoV-2(GenBank No.NC_045512),all six genome sequences shared the same substitutions at nt241(C→T),nt3037(C→T),nt14408(C→T),nt23403(A→G),nt28881(G→A),nt28882(G→A),and nt28883(G→C),which are the characteristic nucleotide substitutions of L-lineage European branch I.This was also proved by themaximum likelihood phylogenetic tree based on the full-length genome of SARS-CoV-2.They also have a unique shared nucleotide substitution,nt6026(C→T),which is the characteristic nucleotide substitution of SARS-CoV-2 in Beijing's Xinfadi outbreak.It is noteworthy that there is an amino acid D614Gmutation caused by nt23403 substitution in all six genomes,which may enhance the virus's infectivity in humans and help it become the leading strain of the virus to spread around the world today.It is necessary to continuously monitor the genetic variation of SARS-CoV-2,focusing on the influence of key mutation sites of SARS-CoV-2 on viral transmission,clinical manifestations,severity,and course of disease. | Yong Zhang Yang Pan Xiang Zhao Weifeng Shi Zhixiao Chen Sheng Zhang Peipei Liu Jinbo Xiao Wenjie Tan Dayan Wang William J.Liu Wenbo Xu Quanyi Wang Guizhen Wu | 2020 | Biosafety and Health2020，2，4： | 3 |
| 3 | The compactness of spatial structure in Chinese cities:measurement,clustering patterns and influencing factors显示文摘Rapid urbanization in China has led to an excessive urban expansion of built-up areas,which makes quantitative research on compact city important.We adopted density and the degree of mixed land use to measure the compactness of 160 Chinese cities.Spatial autocorrelation analysis was performed to identify spatial clustering patterns,and the relationships between compactness and five variables were explored through regression models.The result shows that in nearly half of the cases,the calculated values of two indices are less than the average.The high or low values of density and the degree of mixed land use tend to be spatially clustered.The hot spot regions of density and the degree of mixed land use lie mainly in the south of China,while the north present as cold spots or the insignificant regions.Urban compactness can be affected by multifaceted factors and the relationships between compactness and five variables are not consistent throughout the areas of analysis.The GWR model can identify this phenomenon and provides a better fit than the OLS model.This study proposed a new approach to measure the compactness,and the results of GWR analysis can conducive to appropriate policy-making based on different local conditions. | Fangqi Zhao Lina Tang Quanyi Qiu Gang Wu | 2020 | Ecosystem Health and Sustainability2020，6，1： | 3 |

| 6 | Functional isolation,culture and cryopreservation of adult human primary cardiomyocytes显示文摘Cardiovascular diseases are the most common cause of death globally.Accurately modeling cardiac homeostasis,dysfunction,and drug response lies at the heart of cardiac research.Adult human primary cardiomyocytes(hPCMs)are a promising cellular model,but unstable isolation efficiency and quality,rapid cell death in culture,and unknown response to cryopreservation prevent them from becoming a reliable and flexible in vitro cardiac model.Combing the use of a reversible inhibitor of myosinⅡATPase,(-)-blebbistatin(Bleb),and multiple optimization steps of the isolation procedure,we achieved a 2.74-fold increase in cell viability over traditional methods,accompanied by better cellular morphology,minimally perturbed gene expression,intact electrophysiology,and normal neurohormonal signaling.Further optimization of culture conditions established a method that was capable of maintaining optimal cell viability,morphology,and mitochondrial respiration for at least 7 days.Most importantly,we successfully cryopreserved hPCMs,which were structurally,molecularly,and functionally intact after undergoing the freeze-thaw cycle.hPCMs demonstrated greater sensitivity towards a set of cardiotoxic drugs,compared to human-induced pluripotent stem cell-derived cardiomyocytes(hiPSC-CMs).Further dissection of cardiomyocyte drug response at both the population and single-cell transcriptomic level revealed that hPCM responses were more pronouncedly enriched in cardiac function,whereas hiPSC-CMs responses reflected cardiac development.Together,we established a full set of methodologies for the efficient isolation and prolonged maintenance of functional primary adult human cardiomyocytes in vitro,unlocking their potential as a cellular model for cardiovascular research,drug discovery,and safety pharmacology. | Bingying Zhou Xun Shi Xiaoli Tang Quanyi Zhao Le Wang Fang Yao Yongfeng Hou Xianqiang Wang Wei Feng Liqing Wang Xiaogang Sun Li Wang Shengshou Hu | 2022 | Signal Transduction and Targeted Therapy2022，7，8： | 1 |
| 7 | Tetrahedral framework nucleic acids promote the biological functions and related mechanism of synovium-derived mesenchymal stem cells and show improved articular cartilage regeneration activity in situ显示文摘Many recent studies have shown that joint-resident mesenchymal stem cells(MSCs)play a vital role in articular cartilage(AC)in situ regeneration.Specifically,synovium-derived MSCs(SMSCs),which have strong chondrogenic differentiation potential,may be the main driver of cartilage repair.However,both the insufficient number of MSCs and the lack of an ideal regenerative microenvironment in the defect area will seriously affect the regeneration of AC.Tetrahedral framework nucleic acids(tFNAs),notable novel nanomaterials,are considered prospective biological regulators in biomedical engineering.Here,we aimed to explore whether tFNAs have positive effects on AC in situ regeneration and to investigate the related mechanism.The results of in vitro experiments showed that the proliferation and migration of SMSCs were significantly enhanced by tFNAs.In addition,tFNAs,which were added to chondrogenic induction medium,were shown to promote the chondrogenic capacity of SMSCs by increasing the phosphorylation of Smad2/3.In animal models,the injection of tFNAs improved the therapeutic outcome of cartilage defects compared with that of the control treatments without tFNAs.In conclusion,this is the first report to demonstrate that tFNAs can promote the chondrogenic differentiation of SMSCs in vitro and enhance AC regeneration in vivo,indicating that tFNAs may become a promising therapeutic for AC regeneration. | Liwei Fu Pinxue Li Junyao Zhu Zhiyao Liao Cangjian Gao Hao Li Zhen Yang Tianyuan Zhao Wei Chen Yu Peng Fuyang Cao Chao Ning Xiang Sui Quanyi Guo Yunfeng Lin Shuyun Liu | 2022 | Bioactive Materials2022，7，3： | 1 |

| 9 | MKL1 mediates TNF-α induced pro-inflammatory transcription by bridging the crosstalk between BRG1 and WDR5显示文摘Tumor necrosis factor alpha(TNF-a) is a cytokine that can potently stimulate the synthesis of a range of proinflammatory mediators in macrophages. The underlying epigenetic mechanism, however, is underexplored. Here we report that the transcriptional modulator megakaryocytic leukemia 1(MKL1) is associated with a histone H3 K4 methyltransferase activity. Re-ChIP assay suggests that MKL1 interacts with and recruits WDR5, a component of the COMPASS complex responsible for H3 K4 methylation, to the promoter regions of pro-inflammatory genes in macrophages treated with TNF-α. WDR5 enhances the ability of MKL1 to stimulate the promoter activities of proinflammatory genes. In contrast, silencing of WDR5 attenuates TNF-a induced production of pro-inflammatory mediators and erases the H3 K4 methylation from the gene promoters. Of interest, the chromatin remodeling protein BRG1 also plays an essential role in maintaining H3 K4 methylation on MKL1 target promoters by interacting with WDR5. MKL1 knockdown disrupts the interaction between BRG1 and WDR5. Together, our data illustrate a role for MKL1 in moderating the crosstalk between BRG1 and WDR5 to activate TNF-a induced pro-inflammatory transcription in macrophages. | Wenping Xu Quanyi Zhao Min Wu Mingming Fang Yong Xu | 2019 | The Journal of Biomedical Research2019，33，3： | 1 |

| 11 | Study on pharmacokinetics and tissue distribution of the isocorydine derivative (AICD) in rats by HPLC-DAD method显示文摘A simple and effective high-performance liquid chromatography with diode-array detection method coupled with a liquid-liquid extraction pretreatment has been developed for determining the pharmacokinetics and tissue distribution of a novel structurally modified derivative(8-acetaminoisocorydine) of isocorydine.According to the in vivo experiments data calculations by DAS 2.0 software,a two-compartment metabolic model was suitable for describing the pharmacokinetic of 8-acetaminoisocorydine in rats.8-Acetamino-isocorydine was absorbed well after oral administration,and the absolute bioavailability was 76.5%.The half-life of 8-acetamino-isocorydine after intravenous and oral administration was 2.2 h and 2.0 h,respectively.In vivo,8-acetamino-isocorydine was highly distributed in the lungs,kidney and liver;however,relatively little entered the brain,suggesting that 8-acetaminoisocorydine could not easily pass through the blood brain barrier.Our work describes the first characterization of the pharmacokinetic parameters and tissue distribution of 8-acetamino-isocorydine.The acquired data will provide useful information for the in vivo pharmacology of 8-acetaminoisocorydine,and can be applied to new drug research. | Yali Chen Qian Yan Mei Zhong Quanyi Zhao Junxi Liu Duolong Di Jinxia Liu | 2015 | Acta Pharmaceutica Sinica B2015，5，3： | 0 |
| 12 | Adaptively temporal graph convolution model for epidemic prediction of multiple age groups显示文摘Introduction:Multivariate time series prediction of infectious diseases is significant to public health,and the deep learning method has attracted increasing attention in this research field.Material and methods:An adaptively temporal graph convolution(ATGCN)model,which leams the contact patterns of multiple age groups in a graph-based approach,was proposed for COVID-19 and influenza prediction.We compared ATGCN with autoregressive models,deep sequence learning models,and experience-based ATGCN models in short-term and long-term prediction tasks.Results:Results showed that the ATGCN model performed better than the autoregressive models and the deep sequence learning models on two datasets in both short-term(12.5%and 10%improvements on RMSE)and longterm(12.4%and 5%improvements on RMSE)prediction tasks.And the RMSE of ATGCN predictions fluctuated least in different age groups of COVID-19(0.029±0.003)and influenza(0.059±0.008).Compared with the Ones-ATGCN model or the Pre-ATGCN model,the ATGCN model was more robust in performance,with RMSE of 0.0293 and 0.06 on two datasets when horizon is one.Discussion:Our research indicates a broad application prospect of deep learning in the field of infectious disease prediction.Transmission characteristics and domain knowledge of infectious diseases should be further applied to the design of deep learning models and feature selection.Conclusion:The ATGCN model addressed the multivariate time series forecasting in a graph-based deep learning approach and achieved robust prediction on the confirmed cases of multiple age groups,indicating its great potentials for exploring the implicit interactions of multivariate variables. | Yuejiao Wang Dajun Daniel Zeng Qingpeng Zhang Pengfei Zhao Xiaoli Wang Quanyi Wang Yin Luo Zhidong Cao | 2022 | Fundamental Research2022，2，2： | 0 |
| 13 | Advancing drug delivery to articular cartilage:From single to multiple strategies显示文摘Articular cartilage(AC) injuries often lead to cartilage degeneration and may ultimately result in osteoarthritis(OA) due to the limited self-repair ability. To date, numerous intra-articular delivery systems carrying various therapeutic agents have been developed to improve therapeutic localization and retention, optimize controlled drug release profiles and target different pathological processes. Due to the complex and multifactorial characteristics of cartilage injury pathology and heterogeneity of the cartilage structure deposited within a dense matrix, delivery systems loaded with a single therapeutic agent are hindered from reaching multiple targets in a spatiotemporal matched manner and thus fail to mimic the natural processes of biosynthesis, compromising the goal of full cartilage regeneration. Emerging evidence highlights the importance of sequential delivery strategies targeting multiple pathological processes. In this review, we first summarize the current status and progress achieved in single-drug delivery strategies for the treatment of AC diseases. Subsequently, we focus mainly on advances in multiple drug delivery applications, including sequential release formulations targeting various pathological processes, synergistic targeting of the same pathological process, the spatial distribution in multiple tissues, and heterogeneous regeneration. We hope that this review will inspire the rational design of intraarticular drug delivery systems(DDSs) in the future. | Tianyuan Zhao Xu Li Hao Li Haoyuan Deng Jianwei Li Zhen Yang Songlin He Shuangpeng Jiang Xiang Sui Quanyi Guo Shuyun Liu | 2023 | Acta Pharmaceutica Sinica B2023，13，10： | 0 |
| 14 | Cerium oxide nanozymes alleviate oxidative stress in tenocytes for Achilles tendinopathy healing显示文摘Background:Reactive oxygen species(ROS)is considered as ubiquitous and highly active chemicals that influence tendon integrity and orchestrate tendon repair.With significant recent advances in nanomaterials,cerium oxide nanoparticles(CeO_(2)NPs)exhibit superoxide dismutase-and catalase-like activities.Herein,we introduced a therapeutic approach of CeO_(2)NPs for Achilles tendinopathy(AT)healing.Methods:CeO_(2)NPs were synthesized to examine their effect as ROS scavengers on AT healing in vitro and in vivo.The mRNA levels of inflammatory factors were evaluated in AT after CeO_(2)NPs treatment in vitro.The mechanisms underlying CeO_(2)NPs-mediated stimulation of NRF2 translocation and ERK signaling were verified through immunofluorescence and Western blot analysis.The efficacy of CeO_(2)NPs was tested in an AT rat model in comparison with the control.Results:CeO_(2)NPs not only significantly scavenged multiple ROS and suppressed ROS-induced inflammatory reactions but also protected cell proliferation under oxidative stress induced by tert-butyl hydroperoxide(TBHP).Moreover,CeO_(2)NPs could promote NRF_(2)nuclear translocation for anti-oxidation and anti-inflammation through the ERK signaling pathway.In a rat model of collagenase-induced tendon injuries,CeO_(2)NPs showed significant therapeutic efficacy by ameliorating tendon damage.Conclusion:The present study provides valuable insights into the molecular mechanism of CeO_(2)NPs to ameliorate ROS in tenocytes via the ERK/NRF_(2)signaling pathway,which underscores the potential of CeO_(2)NPs for application in the treatment of enthesopathy healing. | Xingquan Xu Rongliang Wang Yixuan Li Rui Wu Wenjin Yan Sheng Zhao Quanyi Liu Yan Du Wenli Gong Weitong Li Hui Wei Dongquan Shi | 2023 | Nano Research2023，16，5： | 0 |
| 15 | Application of a ddRT-PCR to quantify seasonal influenza virus for viral isolation显示文摘Viral isolation in cell cultures has been regarded for decades as the“gold standard”for the laboratory diagnosis of influenza viral infections.Not all viral strains could be isolated from clinical samples.This study aimed to quantify the viral load in the samples before isolation to save working time and improve working efficiency.Four hundred samples from patients with influenza-like cases were confirmed pdmH1N1 positive(200 cases)and B Victoria(BV)positive(200 cases)by whole-genome sequencing and analyzed by ddPCR for viral load in samples before isolation,and isolation results were verified by hemagglutination(HA)assay and hemagglutination-inhibition(HI)tests.Probit regression analysis was used to calculate the isolation viral load limit with a 95%probability level by SPSS 19.0 software.The results showed that the isolation limit of viral load was 4.9×10^(4)(95%CI:2.5×10^(4)–9.0×10^(4))copies/mL for pdmH1N1 and 1.9×10^(4)(95%CI:7.8×103–3.6×10^(4))copies/mL for BV.The isolation rate of clinical samples is positively correlated with the viral load in clinical samples,which can be used for viral culture,providing important guidance for daily work. | Yimeng Liu Jiachen Zhao Xiaomin Peng Guilan Lu Weixian Shi Zhaomin Feng Hui Xu Shujuan Cui Yang Pan Daitao Zhang Peng Yang Quanyi Wang | 2022 | Biosafety and Health2022，4，5： | 0 |
