| 2 | 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 |
| 3 | PSA controls hepatic lipid metabolism by regulating the NRF2 signaling pathway显示文摘The activity of proteinase is reported to correlate with the development and progression of nonalcoholic fatty liver disease(NAFLD).Puromycin-sensitive aminopeptidase(PSA/NPEPPS)is an integral nontransmembrane enzyme that functions to catalyze the cleavage of amino acids near the N-terminus of polypeptides.A previous study suggested that this enzyme acts as a regulator of neuropeptide activity;however,the metabolic function of this enzyme in the liver has not been explored.Here,we identified the novel role of PSA in hepatic lipid metabolism.Specifically,PSA expression was lower in fatty livers from NAFLD patients and mice(HFD,ob/ob,and db/db).PSA knockdown in cultured hepatocytes exacerbated diet-induced triglyceride accumulation through enhanced lipogenesis and attenuated fatty acid β-oxidation.Moreover,PSA mediated activation of the master regulator of antioxidant response,nuclear factor erythroid 2-related factor 2(NRF2),by stabilizing NRF2 protein expression,which further induced downstream antioxidant enzymes to protect the liver from oxidative stress and lipid overload.Accordingly,liver-specific PSA overexpression attenuated hepatic lipid accumulation and steatosis in ob/ob mice.Furthermore,in human liver tissue samples,decreased PSA expression correlated with the progression of NAFLD.Overall,our findings suggest that PSA is a pivotal regulator of hepatic lipid metabolism and its antioxidant function occurs by suppressing NRF2 ubiquitination.Moreover,PSA may be a potential biomarker and therapeutic target for treating NAFLD. | Bangliang Huang Xin Xiong Linlin Zhang Xiufei Liu Yuren Wang Xiaoli Gong Qian Sang Yongling Lu Hua Qu Hongting Zheng Yi Zheng | 2021 | Journal of Molecular Cell Biology2021，13，7： | 4 |
| 4 | Sequential infection with H1N1 and SARS-CoV-2 aggravated COVID-19 pathogenesis in a mammalian model, and covaccination as an effective method of prevention of COVID-19 and influenza显示文摘Influenza A virus may circulate simultaneously with the SARS-CoV-2 virus,leading to more serious respiratory diseases during this winter.However,the influence of these viruses on disease outcome when both influenza A and SARS-CoV-2 are present in the host remains unclear.Using a mammalian model,sequential infection was performed in ferrets and in K18-MCE2 mice,with SARS-CoV-2 infection following H1N1.We found that co-infection with H1N1 and SARS-CoV-2 extended the duration of clinical manifestation of COVID-19,and enhanced pulmonary damage,but reduced viral shedding of throat swabs and viral loads in the lungs of ferrets.Moreover,mortality was increased in sequentially infected mice compared with single-infection mice.Compared with singlevaccine inoculation,co-inoculation of PiCoVacc(a SARS-CoV-2 vaccine)and the flu vaccine showed no significant differences in neutralizing antibody titers or virus-specific immune responses.Combined immunization effectively protected K18-MCE2 mice against both H1N1 and SARS-CoV-2 infection.Our findings indicated the development of systematic models of co-infection of H1N1 and SARS-CoV-2,which together notably enhanced pneumonia in ferrets and mice,as well as demonstrated that simultaneous vaccination against HINT and SARS-CoV-2 may be an effective prevention strategy for the coming winter. | Linlin Bao Wei Deng Feifei Qi Qi Lv Zhiqi Song Jiangning Liu Hong Gao Qiang Wei Pin Yu Yanfeng Xu Yajin Qu Fengdi Li Jing Xue Shuran Gong Mingya Liu Guanpeng Wang Shunyi Wang Binbin Zhao Bin Cong Chuan Qin | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 4 |
| 5 | SARS-CoV-2 infection aggravates chronic comorbidities of cardiovascular diseases and diabetes in mice显示文摘Background:Cardiovascular diseases(CVDs)and diabetes mellitus(DM)are top two chronic comorbidities that increase the severity and mortality of COVID-19.However,how SARS-CoV-2 alters the progression of chronic diseases remain unclear.Methods:We used adenovirus to deliver h-ACE2 to lung to enable SARS-CoV-2 infection in mice.SARS-CoV-2’s impacts on pathogenesis of chronic diseases were studied through histopathological,virologic and molecular biology analysis.Results:Pre-existing CVDs resulted in viral invasion,ROS elevation and activation of apoptosis pathways contribute myocardial injury during SARS-CoV-2 infection.Viral infection increased fasting blood glucose and reduced insulin response in DM model.Bone mineral density decreased shortly after infection,which associated with impaired PI3K/AKT/mTOR signaling.Conclusion:We established mouse models mimicked the complex pathological symptoms of COVID-19 patients with chronic diseases.Pre-existing diseases could impair the inflammatory responses to SARS-CoV-2 infection,which further aggravated the pre-existing diseases.This work provided valuable information to better understand the interplay between the primary diseases and SARS-CoV-2 infection. | Yuanwu Ma Dan Lu Linlin Bao Yajin Qu Jiangning Liu Xiaolong Qi Lei Yu Xu Zhang Feifei Qi Qi Lv Yunpeng Liu Xudong Shi Caixian Sun Jing Li Jie Wang Yunlin Han Kai Gao Wei Dong Ning Liu Shan Gao Jing Xue Qiang Wei Sidan Pan Hong Gao Lianfeng Zhang Chuan Qin | 2021 | Animal Models and Experimental Medicine2021，4，1： | 3 |
| 6 | Review on observational studies of western tropical Pacific Ocean circulation and climate显示文摘The Western Tropical Pacific(WTP) Ocean holds the largest area of warm water(>28℃) in the world ocean referred to as the Western Pacific Warm Pool(WPWP),which modulates the regional and global climate through strong atmospheric convection and its variability.The WTP is unique in terms of its complex 3-D ocean circulation system and intensive multiscale variability,making it crucial in the water and energy cycle of the global ocean.Great advances have been made in understanding the complexity of the WTP ocean circulation and associated climate impact by the international scientific community since the 1960 s through field experiments.In this study,we review the evolving insight to the 3-D structure and multi-scale variability of the ocean circulation in the WTP and their climatic impacts based on in-situ ocean observations in the past decades,with emphasis on the achievements since 2000.The challenges and open que stions remaining are reviewed as well as future plan for international study of the WTP ocean circulation and climate. | HU Dunxin WANG Fan SPRINTALL Janet WU Lixin RISER Stephen CRAVATTE Sophie GORDON Arnold ZHANG Linlin CHEN Dake ZHOU Hui ANDO Kentaro WANG Jianing LEE Jae-Hak HU Shijian WANG Jing ZHANG Dongxiao FENG Junqiao LIU Lingling VILLANOY Cesar KALUWIN Chalapan QU Tangdong MA Yixin | 2020 | Journal of Oceanology and Limnology2020，38，4： | 3 |

| 10 | Relationship between joint development in rock and coal seams in the southeastern margin of the Ordos basin显示文摘To predict joint development characteristics of coal seams, joint characteristics of rock seams from 88field stations were observed and comparisons were made between joint characteristics of coal and rock seams at 10 coal outcrops. Additionally, detailed joint measurements of underground coal seams were taken at two coal mines. This study investigated the effects of seam thickness, lithology, and structure on joint development and established the relationship between joint development of coal and rock seams, which allowed predictions of predominant joint densities for the No.5 coal seam in the southeastern margin of the Ordos basin. The results show that outcrop and underground coal seams exhibit the same joint systems as rock seams. The joints are mainly upright. Predominant joints strike 55° on average, followed by joints striking 320°. The joint density of the coal seam is 18.7–22.5 times that of the sandstone seam at the same thickness. The predominant joint density of the No.5 coal seam, controlled by the structure, is 4–20 joints per meter. Joint densities exhibit high values at intersecting areas of faults and folds and decrease values in structurally stable areas. The permeability increases exponentially with increasing density of the predominant joints. | Wang Linlin Jiang Bo Wang Jilin Qu Zhenghui Li Pei Liu Jiegang | 2014 | International Journal of Mining Science and Technology2014，24，2： | 1 |

| 12 | A novel degradable injectable HLC-HPA hydrogel with antiinflammatory activity for biomedical materials:Preparation,characterization,in vivo and in vitro evaluation显示文摘In situ injectable hydrogels,which have great potential in tissue engineering,are characterized by simple preparation,minimal invasiveness and adaptation to complex shapes.However,injectable hydrogels have higher requirements for biocompatibility and safety due to their use in vivo implantation.Therefore,in this study,a human-like collagen(HLC)-based in situ gel-forming injectable HLC-HPA hydrogel was synthesized by combining the amino group of HLC with the carboxyl group of HPA activated using 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride(EDC)and N-hydroxysuccinimide(NHS),followed by crosslinking by horseradish peroxidase(HRP)and H_2O_2,and used as scaffold material for tissue engineering.The hydrogel stiffness,gel time and biodegradation rate could be easily and independently adjusted by varying the H_2O_2 and HRP concentrations.Scanning electron microscope(SEM)clarified the homogeneous porous and interconnected internal structures of the hydrogel.In vitro cell viability and in vivo degradation experiments confirmed that the HLC-HPA hydrogel had good biodegradability and excellent biocompatibility.Interestingly,in cultured macrophages,the HLC-HPA hydrogel showed anti-inflammatory activity by reducing the amount of the pro-inflammatory cytokines tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)and increasing the secretion of the anti-inflammatory cytokine interleukin-10(IL-10)induced by lipopolysaccharide(LPS).Meanwhile,in animal experiments,HLC-HPA hydrogels exhibit excellent biocompatibility and have properties of hemostasis and reduction of inflammatory response.Therefore,the HLC-HPA hydrogel prepared in this study has great potential for development for use in the biomedical field. | GAO Shang QU LinLin ZHU ChenHui OUYANG PingKai FAN DaiDi | 2020 | Science China(Technological Sciences)2020，63，11： | 1 |
| 13 | Ginsenoside Rk3 is a novel PI3K/AKT-targeting therapeutics agent that regulates autophagy and apoptosis in hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is the third leading cause of cancer death worldwide.Ginsenoside Rk3,an important and rare saponin in heat-treated ginseng,is generated from Rg1 and has a smaller molecular weight.However,the anti-HCC efficacy and mechanisms of ginsenoside Rk3 have not yet been characterized.Here,we investigated the mechanism by which ginsenoside Rk3,a tetracyclic triterpenoid rare ginsenoside,inhibits the growth of HCC.We first explored the possible potential targets of Rk3 through network pharmacology.Both in vitro(HepG2 and HCC-LM3 cells)and in vivo(primary liver cancer mice and HCC-LM3 subcutaneous tumor-bearing mice)studies revealed that Rk3 significantly inhibits the proliferation of HCC.Meanwhile,Rk3 blocked the cell cycle in HCC at the G1 phase and induced autophagy and apoptosis in HCC.Further proteomics and siRNA experiments showed that Rk3 regulates the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)pathway to inhibit HCC growth,which was validated by molecular docking and surface plasmon resonance.In conclusion,we report the discovery that ginsenoside Rk3 binds to PI3K/AKT and promotes autophagy and apoptosis in HCC.Our data strongly support the translation of ginsenoside Rk3 into novel PI3K/AKT-targeting therapeutics for HCC treatment with low toxic side effects. | Linlin Qu Yannan Liu Jianjun Deng Xiaoxuan Ma Daidi Fan | 2023 | Journal of Pharmaceutical Analysis2023，13，5： | 1 |

| 15 | Stretchable graded multichannel self-powered respiratory sensor inspired by shark gill显示文摘Respiratory sensing provides a simple,non-invasive,and efficient way for medical diagnosis and health monitoring,but it relies on sensors that are conformal,accurate,durable,and sustainable working.Here,a stretchgll structure can convert transverse elastic deformation into longitudinal elastic deformation during stretching.able,multichannel respiratory sensor inspired by the structure of shark gill cleftis reported.The bionic shark Combining the optimized bionic shark gll structure with the piezoelectric and the triboelectric effect,the bionic shark gill respiratory sensor(BSG-RS)can produce a graded electrical response to different tensile strains.Based on this feature,BSG-RS can simultaneously monitor the breathing rate and breathing depth of the human body accurately,and realize the effective recognition of the different human body's breathing state under the supporting software,With good stretchability,wearabilit,acuracy,and long-term stability(50,0oo cycles),BSG-RS is expected to be applied as self-powered smart wearables for mobile medical diagnostic analysis in the future. | Yang Zou Yansong Gai Puchuan Tan Dongjie Jiang Xuecheng Qu Jiangtao Xue Han Ouyang Bojing Shi Linlin Li Dan Luo Yulin Deng Zhou Li Zhong Lin Wang | 2022 | Fundamental Research2022，2，4： | 1 |
| 16 | Structures,properties,and applications of zwitterionic polymers显示文摘Zwitterionic polymers have attracted research attention in recent years owing to their unique molecular struc-tures.In the same repeat unit,positive and negative charges are simultaneously located on a pair of cationic and anionic groups;therefore,zwitterionic polymers have a large dipole moment and numerous charged groups.Al-though the molecular chain of the zwitterionic polymer can be maintained in an electrically neutral state overall,the coexistence of the oppositely charged groups confers extremely high polarity and excellent hydrophilicity to the polymer.At the same time,the electricality of the polymer can be further regulated by the environmental pH and salt ions,which greatly broadens the scope of applications in different fields.This review introduces various structures of zwitterionic polymers and analyzes the reasons why zwitterionic polymers exhibit pH responsive-ness,anti-polyelectrolyte effects,and superior electrical conductivity.The application fields are also summarized by generalizing the research status of zwitterionic polymers,including applications in antifouling coatings,drug delivery,wastewater treatment,and sensors,etc. | Keyu Qu Zhiang Yuan Yanyan Wang Zhaohui Song Xuyang Gong Yi Zhao Qiyu Mu Qinghong Zhan Wenlong Xu Linlin Wang | 2022 | ChemPhysMater2022，1，4： | 0 |
| 17 | Filamentation initiated by Cas2 and its association with the acquisition process in cells显示文摘Cas1-and-Cas2-mediated new spacer acquisition is an essential process for bacterial adaptive immunity.The process is critical for the ecology of the oral microflora and oral health.Although molecular mechanisms for spacer acquisition are known,it has never been established if this process is associated with the morphological changes of bacteria.In this study,we demonstrated a novel Cas2-induced filamentation phenotype in E.coli that was regulated by co-expression of the Cas1 protein.A 30 amino acid motif at the carboxyl terminus of Cas2 is necessary for this function.By imaging analysis,we provided evidence to argue that Cas-induced filamentation is a step coupled with new spacer acquisition during which filaments are characterised by polyploidy with asymmetric cell division.This work may open new opportunities to investigate the adaptive immune response and microbial balance for oral health. | Lei Wang Xin Yu Mengjie Li Guiqin Sun Lin Zou Tiansheng Li Linlin Hou Yameng Guo Danfeng Shen Di Qu Xunjia Cheng Li Chen | 2019 | International Journal of Oral Science2019，11，4： | 0 |
| 18 | Intravenous injection of AAV-PHP.eB across the blood-brain barrier in the adult mouse for central nervous system gene therapy显示文摘Objective To verify the neurotypicality of AAV-PHP.eB after tail vein injection in adult mice and its efficiency in crossing the blood-brain barrier(BBB).Methods The rAAV-SYN-GFP plasmid was constructed, and adult C57 BL mice were injected with AAV PHP.eB: SYN-GFP in the tail vein(300 nL, virus titer 3 × 10~9 vg) and in the prefrontal lobe(50 L, virus tite5 × 10^(11) vg). The green fluorescent protein(GFP) signal in the brain was observed at two weeks, while the GFP signal in the peripheral organs was observed at four weeks. Results Two weeks after tail vein injection, GFP expression was observed throughout the brain especially in the cortex, hippocampus, and geniculate nucleus. No GFP signal was observed or detected by western blotting in the peripheral organs after four weeks. GFP signal was observed mainly at the loca site after prefrontal lobe injection.Conclusion AAV-PHP.eB: SYN-GFP can effectively cross the BBB in adult mice. Using a neuron-specific promoter allows exogenous gene expression in neurons; therefore, AAV-PHP.eB can be used as an effective carrier for studying diseases in the central nervous system(CNS). | Yongwei Shu Jie Yao Yang Qu Jing Zheng Jing Ding Lina Zhang Yefan Wang Linlin Zhao Jingyu Zhang Siqi Tang | 2019 | Oncology and Translational Medicine2019，5，1： | 0 |

| 20 | Phenotypic and Genetic Characteristics of a Bordetella hinzii Isolated from a Rex Rabbit显示文摘A Bordetella hinzii strain,isolated from the lung of a dead breast-feeding infant rex rabbit with a respiratory infection,was used as study object to investigate its phenotypic and genetic characteristics. The strain could grow on Mac Conkey agar and was gram-negative,oxidase-positive,catalase-positive,short rodshaped,and it can produce alkali from malonate. Its 6S rRNA sequence was partially identical with B. hinzii( AF177667). Animal experiments revealed nasal mucous hyperemia,tracheal congestion and bronchopneumonia in 28-day old rex rabbits. To sum up,this Bordetella hinzii isolate was deemed as a novel causative agent of respiratory disease in rex rabbit. | Li Shuguang Shen Zhiqiang Qu Guanggang Guan Yu Fu Shijun Hu Linlin Wang Yumao | 2015 | Animal Husbandry and Feed Science2015，7，3： | 0 |
