| 1 | Acetylenes and fatty acids from Codonopsis pilosula显示文摘Four new acetylenes(1–4) and one new unsaturated ω-hydroxy fatty acid(5),together with 5known analogues,were isolated from an aqueous extract of Codonopsis pilosula roots.Their structures were determined by spectroscopic and chemical methods.The new acetylenes are categorized as an unusual cyclotetradecatrienynone(1),tetradecenynetriol(2),and rare octenynoic acids(3 and 4),respectively,and 3 and 4 are possibly derived from oxidative metabolic degradation of 1 and/or 2.The absolute configuration of 1 was assigned by comparison of the experimental circular dichroism(CD)spectrum with the calculated electronic circular dichroism(ECD) spectra of stereoisomers based on the quantum-mechanical time-dependent density functional theory,while the configuration of 2 was assigned by using modified Mosher's method based on the MPA determination rule of ΔδRSvalues for diols. | Yueping Jiang Yufeng Liu Qinglan Guo Zhibo Jiang Chengbo Xu Chenggen Zhu Yongchun Yang Sheng Lin Jiangong Shi | 2015 | Acta Pharmaceutica Sinica B2015，5，3： | 15 |
| 2 | Impact of anthropogenic activities on the sediment microbial communities of Baiyangdian shallow lake显示文摘Microorganisms are recognized as sensors of external disturbance in freshwater ecosystems.In this study,sediment samples from regions with strong human activity interference(four sites),moderate human activity interference(five sites)and minor human activity interference(five sites)in Baiyangdian Lake were collected;and their physiological and chemical properties and heavy metals contents were analyzed.The structures of bacterial and fungal communities were tested using 16S ribosomal Ribonucleic Acid(rRNA)and Internal Transcribed Spacer 2(ITS2)high-throughput sequencing technologies.The results indicated that Proteobacteria was the most abundant bacterial phylum.Ascomycota,Basidiomycota and Ciliophora were the dominant phyla of fungi.Obvious differences of microbial genera among the three regions were observed,especially fungal genera.With intensified disturbance by human activities,the Simpson and Shannon indices of bacteria significantly decreased.The fungal communities were clustered into three groups in accordance with the different human disturbance levels.The bacterial communities of sediment samples under moderate and minor human disturbance appeared similar,but different from those under strong human disturbance.Redundancy analysis indicated that zinc,total phosphorus,copper,and lead were the dominant factors that influenced the bacterial community.Nitrifiers and sulfate-reducing bacteria were influenced by pH,nitrate(NO3 ),and total nitrogen.The fungal community was significantly affected by total phosphorus.This study reveals that sediment microbial community structures among different regions of a shallow lake are mainly impacted by human activities. | Wenjun Wang Yujun Yi Yufeng Yang Yang Zhou Shanghong Zhang Xuan Wang Zhifeng Yang | 2020 | International Journal of Sediment Research2020，35，2： | 14 |
| 3 | Clinical characteristics and effectiveness of antiviral agents in hospitalized children with infectious mononucleosis in China:A multicenter retrospective study显示文摘Importance:The clinical characteristics of infectious mononucleosis(IM)in Chinese children have not been evaluated in multicenter studies,and the effectiveness of antiviral treatment are controversial.Objective:To investigate the clinical characteristics of Chinese children with IM and current status of antiviral therapy for affected patients.Methods:Hospitalized patients with IM were enrolled between 2018 and 2020 in five children’s hospitals in China.The clinical characteristics were compared among four age groups:<3 years,3-<6 years,6-<10 years,and≥10 years.The clinical characteristics of IM and effectiveness of antiviral therapy were compared among patients receiving acyclovir(ACV),ganciclovir(GCV),and no antiviral therapy(i.e.,non-antiviral group).Results:In total,499 patients were analyzed;most patients were 3-<6 years of age.The most common symptoms and signs included fever(100%),lymphadenopathy(98.6%),pharyngitis(86.4%),eyelid edema(76.8%),and snoring(72.9%).There were significant differences in rash,hepatomegaly,and liver dysfunction among the four age groups.Patients aged<3 years had a lower incidence of liver dysfunction and a higher incidence of rash.Among the 499 patients,50.1%were treated with GCV,26.3%were treated with ACV,and 23.6%received no antiviral therapy.Compared with the non-antiviral group,patients in the ACV and GCV groups had longer durations of fever(P<0.001).There were no significant differences in the incidences of complications among the three treatment groups.Interpretation:The incidence of IM in Chinese children peaked at 3-<6 years of age.Clinical features of IM varied according to age.Patients receiving antiviral therapy exhibited more serious clinical manifestations than did patients without antiviral therapy.The effectiveness of antiviral therapy for IM requires further analysis. | Huili Hu Huiling Deng Jing Bi Yi Xu Shuangjie Li Yue Xie Xinrong Sun Dongmeng Wang Xufang Li Wenxian Ouyang Bing Hu Yufeng Zhang He Tang Chunxiao Fang Hui Zhang Lingyun Guo Chen Wang Tianyi Wang Fengxia Yang Tao Jiang Zhengde Xie Gang Liu | 2021 | Pediatric Investigation2021，5，3： | 12 |
| 4 | Growth response and toxic effects of three antibiotics on Selenastrum capricornutum evaluated by photosynthetic rate and chlorophyll biosynthesis显示文摘The effects of three types of antibiotics (erythromycin,ciprofloxacin and sulfamethoxazole) on the photosynthesis of freshwater algae,Selenastrum capricornutum Printz,were investigated by determining the growth rate,chloroplast pigments content,seven main precursors (including δ-aminolevulinic acid,porphobilinogen,uroporphyrinogen III,coproporphyrinogen III,protoporphyrin IX,Mg-proporphyrin IX and protochlorophyllide),and photosynthetic rate during chlorophyll biosynthesis.The antibiotics significantly decreased the growth rate,chlorophyll content,and photosynthetic rate.Erythromycin induced a decreasing effect at a concentration of 0.06 mg/L,while ciprofloxacin and sulfamethoxazole achieved the same results at concentrations higher than 1.5 mg/L.Only erythromycin significantly inhibited chlorophyll biosynthesis,which indicated that it was considerably more toxic to S.capricornutum than ciprofloxacin and sulfamethoxazole,and may pose a high potential risk to aquatic ecosystems. | Binyang Liu Weiqiu Liu Xiangping Nie Chao Guan Yufeng Yang Zhaohui Wang Wei Liao | 2011 | Journal of Environmental Sciences2011，23，9： | 11 |
| 5 | Research status of biodegradable metals designed for oral and maxillofacial applications:A review显示文摘The oral and maxillofacial regions have complex anatomical structures and different tissue types,which have vital health and aesthetic functions.Biodegradable metals(BMs)is a promising bioactive materials to treat oral and maxillofacial diseases.This review summarizes the research status and future research directions of BMs for oral and maxillofacial applications.Mg-based BMs and Zn-based BMs for bone fracture fixation systems,and guided bone regeneration(GBR)membranes,are discussed in detail.Zn-based BMs with a moderate degradation rate and superior mechanical properties for GBR membranes show great potential for clinical translation.Fe-based BMs have a relatively low degradation rate and insoluble degradation products,which greatly limit their application and clinical translation.Furthermore,we proposed potential future research directions for BMs in the oral and maxillofacial regions,including 3D printed BM bone scaffolds,surface modification for BMs GBR membranes,and BMs containing hydrogels for cartilage regeneration,soft tissue regeneration,and nerve regeneration.Taken together,the progress made in the development of BMs in oral and maxillofacial regions has laid a foundation for further clinical translation. | Dandan Xia Fan Yang Yufeng Zheng Yunsong Liu Yongsheng Zhou | 2021 | Bioactive Materials2021，6，11： | 9 |
| 6 | An analytical solution to the scattering of cylindrical SH waves by a partially filled semi-circular alluvial valley: near-source site effects显示文摘The earth's surface irregularities can substantially affect seismic waves and induce amplifi cations of ground motions. This study investigates whether and how the source characteristics affect the site amplifi cation effects. An analytical model of a line source of cylindrical waves impinging on an alluvial valley is proposed to link the source and site. The analytical solution to this problem proves one aspect of the strong effect of source on site amplifi cation, i.e., the wave curvature effect. It is found that the site amplifi cation depends on the source location, especially under conditions of a small source-to-site distance. Whether the displacement is amplifi ed or reduced and the size of the amplifi cation or reduction may be determined by the location of the source. It is suggested that traditional studies of site responses, which usually ignore the source effect, should be further improved by combining the source with site effects. | Zhang Ning Gao Yufeng Yang Jie Xu Changjie | 2015 | Earthquake Engineering and Engineering Vibration2015，14，2： | 9 |
| 7 | Biodegradable Zn-Sr alloy for bone regeneration in rat femoral condyle defect model: In vitro and in vivo studies显示文摘Bone defects are commonly caused by severe trauma,malignant tumors,or congenital diseases and remain among the toughest clinical problems faced by orthopedic surgeons,especially when of critical size.Biodegradable zinc-based metals have recently gained popularity for their desirable biocompatibility,suitable degradation rate,and favorable osteogenesis-promoting properties.The biphasic activity of Sr promotes osteogenesis and inhibits osteoclastogenesis,which imparts Zn-Sr alloys with the ideal theoretical osteogenic properties.Herein,a biodegradable Zn-Sr binary alloy system was fabricated.The cytocompatibility and osteogenesis of the Zn-Sr alloys were significantly better than those of pure Zn in MC3T3-E1 cells.RNA-sequencing illustrated that the Zn-0.8Sr alloy promoted osteogenesis by activating the wnt/β-catenin,PI3K/Akt,and MAPK/Erk signaling pathways.Furthermore,rat femoral condyle defects were repaired using Zn-0.8Sr alloy scaffolds,with pure Ti as a control.The scaffold-bone integration and bone ingrowth confirmed the favorable in vivo repair properties of the Zn-Sr alloy,which was verified to offer satisfactory biosafety based on the hematoxylin-eosin(H&E)staining and ion concentration testing of important organs.The Zn-0.8Sr alloy was identified as an ideal bone repair material candidate,especially for application in critical-sized defects on load-bearing sites due to its favorable biocompatibility and osteogenic properties in vitro and in vivo. | Bo Jia Hongtao Yang Zechuan Zhang Xinhua Qu Xiufeng Jia Qiang Wu Yu Han Yufeng Zheng Kerong Dai | 2021 | Bioactive Materials2021，6，6： | 9 |
| 8 | Large-eddy simulation of shock-wave/turbulent boundary layer interaction with and without Spark Jet control显示文摘The efficiency and mechanism of an active control device ‘‘Spark Jet' and its application in shock-induced separation control are studied using large-eddy simulation in this paper.The base flow is the interaction of an oblique shock-wave generated by 8° wedge and a spatially-developing Ma = 2.3 turbulent boundary layer.The Reynolds number based on the incoming flow property and the boundary layer displacement thickness at the impinging point without shock-wave is20000.The detailed numerical approaches were presented.The inflow turbulence was generated using the digital filter method to avoid artificial temporal or streamwise periodicity.The numerical results including velocity profile,Reynolds stress profile,skin friction,and wall pressure were systematically validated against the available wind tunnel particle image velocimetry(PIV) measurements of the same flow condition.Further study on the control of flow separation due to the strong shock-viscous interaction using an active control actuator ‘‘Spark Jet' was conducted.The single-pulsed characteristic of the device was obtained and compared with the experiment.Both instantaneous and time-averaged flow fields have shown that the jet flow issuing from the actuator cavity enhances the flow mixing inside the boundary layer,making the boundary layer more resistant to flow separation.Skin friction coefficient distribution shows that the separation bubble length is reduced by about 35% with control exerted. | Yang Guang Yao Yufeng Fang Jian Gan Tian Li Qiushi Lu Lipeng | 2016 | Chinese Journal of Aeronautics2016，29，3： | 8 |
| 9 | Study on Biogenic Amines in Various Dry Salted Fish Consumed in China显示文摘This study was carried out to investigate the biogenic amines(BAs), physicochemical property and microorganisms in dry salted fish, a traditional aquatic food consumed in China. Forty three samples of dry salted fish were gathered from retail and wholesale markets and manufacturers, which had been produced in various regions in China. Cadaverine(CAD) and putrescine(PUT) were quantitatively the most common biogenic amines. About 14% of the samples exceeded the histamine content standards established by the FDA and/or EU. The highest histamine content was found in Silver pomfret(Pampus argenteus)(347.79 mg kg^(-1)). Five of forty three samples exceeded the acceptable content of TYR(100 mg kg^(-1)), and 23.26% of dried-salted fish contained high contents of biogenic amines(above 600 mg kg^(-1)). In addition, species, regions, pickling processes and drying methods made the physicochemical property, microorganisms and biogenic amines in dry salted fish to be different to some extents. The total plate count(TPC) was much higher than that of total halophilic bacteria in all samples. The biogenic amines, physicochemical property and microbiological counts exhibited large variations among samples. Furthermore, no significant correlation between biogenic amines and physicochemical property and TPC was observed. This study indicated that dry salted fish may still present healthy risk for BAs, depending on the processing methods, storage conditions among others. | WU Yanyan CHEN Yufeng LI Laihao YANG Xianqing YANG Shaoling LIN Wanling ZHAO Yongqiang DENG Jianchao | 2016 | Journal of Ocean University of China2016，15，4： | 8 |
| 10 | Biochemical sensing in graphene-enhanced microfiber resonators with individual molecule sensitivity and selectivity显示文摘Photonic sensors that are able to detect and track biochemical molecules offer powerful tools for information acquisition in applications ranging from environmental analysis to medical diagnosis.The ultimate aim of biochemical sensing is to achieve both quantitative sensitivity and selectivity.As atomically thick films with remarkable optoelectronic tunability,graphene and its derived materials have shown unique potential as a chemically tunable platform for sensing,thus enabling significant performance enhancement,versatile functionalization and flexible device integration.Here,we demonstrate a partially reduced graphene oxide(prGO)inner-coated and fiber-calibrated Fabry-Perot dye resonator for biochemical detection.Versatile functionalization in the prGO film enables the intracavity fluorescent resonance energy transfer(FRET)to be chemically selective in the visible band.Moreover,by measuring the intermode interference via noise canceled beat notes and locked-in heterodyne detection with Hz-level precision,we achieved individual molecule sensitivity for dopamine,nicotine and single-strand DNA detection.This work combines atomic-layer nanoscience and high-resolution optoelectronics,providing a way toward high-performance biochemical sensors and systems. | Zhongxu Cao Baicheng Yao Chenye Qin Run Yang Yanhong Guo Yufeng Zhang Yu Wu Lei Bi Yuanfu Chen Zhenda Xie Gangding Peng Shu-Wei Huang Chee Wei Wong Yunjiang Rao | 2019 | Light(Science & Applications)2019，8，1： | 8 |
| 11 | Corrosion of magnesium and magnesium–calcium alloy in biologically-simulated environment显示文摘A study of biocompatibility and corrosion of both metallic magnesium(Mg) and a magnesium alloy containing 1% calcium(Mg–Ca) were investigated in in vitro culture conditions with and without the presence of bone marrow derived human mesenchymal stem cells(h MSCs).Chemical analysis of the degraded samples was performed using XRD and FEGSEM. The results from the XRD analysis strongly suggested that crystalline phase of magnesium carbonate was present on the surface of both the Mg and Mg–Ca samples. Flame absorption spectrometry was used to analyse the release of magnesium and calcium ions into the cell culture medium. Magnesium concentration was kept consistently at a level ranging from 40 to 80 m M for both Mg and Mg–Ca samples. No cell growth was observed when in direct contact with the metals apart from a few cells observed at the bottom of culture plate containing Mg–Ca alloy. In general, in vitro study of corrosion of Mg–Ca in a biologicallysimulated environment using cell culture medium with the presence of h MSCs demonstrated close resemblances to in vivo corrosion. Although in vitro corrosion of Mg–Ca revealed slow corrosion rate and no immediate cytotoxicity effects to h MSCs, its corrosion rate was still too high to achieve normal stem cell growth when cells and alloys were cultured in vitro in direct contact. | Richard Harrison Diana Maradze Simon Lyons Yufeng Zheng Yang Liu | 2014 | Progress in Natural Science:Materials International2014，24，5： | 8 |

| 13 | The signal pathways and treatment of cytokine storm in COVID-19显示文摘The Coronavirus Disease 2019(COVID-19)pandemic has become a global crisis and is more devastating than any other previous infectious disease.It has affected a significant proportion of the global population both physically and mentally,and destroyed businesses and societies.Current evidence suggested that immunopathology may be responsible for COVID-19 pathogenesis,including lymphopenia,neutrophilia,dysregulation of monocytes and macrophages,reduced or delayed type I interferon(IFN-I)response,antibody-dependent enhancement,and especially,cytokine storm(CS).The CS is characterized by hyperproduction of an array of pro-inflammatory cytokines and is closely associated with poor prognosis.These excessively secreted pro-inflammatory cytokines initiate different inflammatory signaling pathways via their receptors on immune and tissue cells,resulting in complicated medical symptoms including fever,capillary leak syndrome,disseminated intravascular coagulation,acute respiratory distress syndrome,and multiorgan failure,ultimately leading to death in the most severe cases.Therefore,it is clinically important to understand the initiation and signaling pathways of CS to develop more effective treatment strategies for COVID-19.Herein,we discuss the latest developments in the immunopathological characteristics of COVID-19 and focus on CS including the current research status of the different cytokines involved.We also discuss the induction,function,downstream signaling,and existing and potential interventions for targeting these cytokines or related signal pathways.We believe that a comprehensive understanding of CS in COVID-19 will help to develop better strategies to effectively control immunopathology in this disease and other infectious and inflammatory diseases. | Lan Yang Xueru Xie Zikun Tu Jinrong Fu Damo Xu Yufeng Zhou | 2021 | Signal Transduction and Targeted Therapy2021，6，8： | 7 |
| 14 | Niobium pentoxide:a promising surface-enhanced Raman scattering active semiconductor substrate显示文摘Surface-enhanced Raman scattering technique,as a powerful tool to identify the molecular species,has been severely restricted to the noble metals.The surface-enhanced Raman scattering substrates based on semiconductors would overcome the shortcomings of metal substrates and promote development of surface-enhanced Raman scattering technique in surface science,spectroscopy,and biomedicine studies.However,the detection sensitivity and enhancement effects of semiconductor substrates are suffering from their weak activities.In this work,a semiconductor based on Nb_(2)O_(5) is reported as a new candidate for highly sensitive surfaceenhanced Raman scattering detection of dye molecules.The largest enhancement factor value greater than 107 was observed with the laser excitation at 633 and 780 nm for methylene blue detection.As far as literature review shows,this is in the rank of the highest sensitivity among semiconductor materials;even comparable to the metal nanostructure substrates with“hot spots”.The impressive surface-enhanced Raman scattering activities can be attributed to the chemical enhancement dominated by the photoinduced charge transfer,as well as the electromagnetic enhancement,which have been supported by the density-functional-theory and finite element method calculation results.The chemisorption of dye on Nb_(2)O_(5) creates a new highest occupied molecular orbital and lowest unoccupied molecular orbital contributed by both fragments in the molecule-Nb_(2)O_(5) system,which makes the charge transfer more feasible with longer excitation wavelength.In addition,the electromagnetic enhancement mechanism also accounts for two orders of magnitude enhancement in the overall enhancement factor value.This work has revealed Nb_(2)O_(5) nanoparticles as a new semiconductor surface-enhanced Raman scattering substrate that is able to replace noble metals and shows great potentials applied in the fields of biology related. | Yufeng Shan Zhihui Zheng Jianjun Liu Yong Yang Zhiyuan Li Zhengren Huang Dongliang Jiang | 2017 | npj Computational Materials2017，，1： | 7 |
| 15 | Serum zinc levels and multiple health outcomes: Implications for zinc-based biomaterials显示文摘Background:Zinc-based biomaterials,including biodegradable metal,nanoparticles,and coatings used in medical implants release zinc ions that may increase the whole-body and serum zinc concentrations.The impact of serum zinc concentrations on major health outcomes can provide insights for device design and clinical transformation of zinc-based biomaterials.Methods:This nationally representative cross-sectional study enrolled participants from the National Health and Nutrition Examination Survey(NHANES,2011-2014)including 3607 participants.Using unadjusted and multivariate-adjusted logistic regression analyses,two-piecewise linear regression model with a smoothing function and threshold level analysis,we evaluated the associations between elevated serum zinc levels and major health outcomes.Results:Elevated serum zinc levels were significantly associated with an increase in total spine and total femur bone mineral density(BMD).Every 10μg/dL increase was associated with a 1.12-fold increase in diabetes mellitus(DM)and 1.23-fold and 1.29-fold increase in cardiovascular diseases(CVD)and coronary heart disease(CHD),in participants with serum zinc levels≥100μg/dL.It had no significant linear or nonlinear associations with risk of fractures,congestive heart failure,heart attack,thyroid disease,arthritis,osteoarthritis,rheumatoid arthritis,dyslipidemia and cancer.Conclusion:Serum zinc levels are significantly associated with increased BMD in the total spine and total femur,and risk of DM,and CVD/CHD among participants with serum zinc levels≥100μg/dL. | Xinhua Qu Hongtao Yang Zhifeng Yu Bo Jia Han Qiao Yufeng Zheng Kerong Dai | 2020 | Bioactive Materials2020，5，2： | 7 |
| 16 | Source apportionment and ecological risk assessment of PAHs in surface sediments from the Liaodong Bay,northern China显示文摘The sources and ecological risk from sixteen polycyclic aromatic hydrocarbons in surface sediment in the Liaodong Bay were investigated from 2014 to 2015.The total concentrations of PAHs ranged from 88.5 to 347.1 ng/g,and the high value occurred in the central region of the Liaodong Bay.Cluster analysis identified two site clusters representing the coastal region affected by land-based pollution and the central region of the Liaodong Bay.Principal component analysis-multiple linear regression and diagnostic ratios suggested that PAHs contaminants originated from a mixture of combustion and petroleum sources,and the major was combustion sources.Based on sediment quality guideline,naphthalene,acenaphthylene,acenaphthene,phenanthrene and dibenz[a,h]anthracene may occasionally cause adverse biological effects in some stations.The toxic equivalent concentrations of carcinogenic PAHs indicated low carcinogenic risk for the Liaodong Bay.The ecological risk and toxic pollution levels of PAHs were higher in the central region than in the coastal region along the Liaodong Bay. | ZHANG Yufeng WU Jinhao SONG Lun SONG Yonggang YANG Meng WANG Nianbin HAN Jiabo GUAN Daoming | 2018 | Acta Oceanologica Sinica2018，37，4： | 6 |

| 18 | Cross-cultural adaption and psychometric properties of the Chinese version of the Diabetes Behavior Rating Scale: a pilot study显示文摘Self-care behavior plays a major role in diabetic management. However, in China, a satisfactory instrument has not yet been developed to evaluate the compliance of self-care behavior for young patients with type 1 diabetes mellitus(T1 DM). The Diabetes Behavior Rating Scale(DBRS) has a potential to be the first mature instrument. The purpose of this study is to cross-culturally adapt the DBRS, and preliminarily evaluate its psychometric properties. The instrument translation included translation, back translation and culture adaptation. Psychometric properties were assessed in a sample of 116 young patients with T1 DM adapting insulin injection therapy. The Chinese version of the DBRS was divided to four subscales. Cronbach's α for the total scale was 0.92. The mean inter-item and item-total correlations were 0.35 and 0.54 respectively. Test-retest reliability showed good temporal stability(r=0.81, P=0.001). Negative correlations were found between DBRS scores with the Diabetes Distress Scale scores(r=.0.32, P=0.003) and hemoglobin A1 c(HbA1 c) levels(r=.0.36, P=0.002). Higher DBRS scores correlated with better glycemic control. The Chinese insulin injection therapy version of the DBRS is well translated and culturally adapted. It shows good overall reliability and validity and appears to be a valuable tool for assessing the diabetic self-care behaviors for young patients with T1 DM. | Jing Zhu Jingjing Xu Yang Chen Yong Gu Li Ji Yufeng Zhou Min Zhu Hsiang-Ting Hsu Xiaoping Huang Cuiping Yuan Yun Shi Dan Yan Lili Xie Shuang Chen Tao Yang Wei He | 2018 | Science China(Life Sciences)2018，61，3： | 6 |
| 19 | CD147 antibody specifically and effectively inhibits infection and cytokine storm of SARS-CoV-2 and its variants delta,alpha,beta,and gamma显示文摘SARS-CoV-2 mutations contribute to increased viral transmissibility and immune escape,compromising the effectiveness of existing vaccines and neutralizing antibodies.An in-depth investigation on COVID-19 pathogenesis is urgently needed to develop a strategy against SARS-CoV-2 variants.Here,we identified CD147 as a universal receptor for SARS-CoV-2 and its variants.Meanwhile,Meplazeumab,a humanized anti-CD147 antibody,could block cellular entry of SARS-CoV-2 and its variants-alpha,beta,gamma,and delta,with inhibition rates of 68.7,75.7,52.1,52.1,and 62.3%at 60μg/ml,respectively.Furthermore,humanized CD147 transgenic mice were susceptible to SARS-CoV-2 and its two variants,alpha and beta.When infected,these mice developed exudative alveolar pneumonia,featured by immune responses involving alveoli-infiltrated macrophages,neutrophils,and lymphocytes and activation of IL-17 signaling pathway.Mechanistically,we proposed that severe COVID-19-related cytokine storm is induced by a'spike protein-CD147-CyPA signaling axis':Infection of SARS-CoV-2 through CD147 initiated the JAK-STAT pathway,which further induced expression of cyclophilin A(CyPA);CyPA reciprocally bound to CD147 and triggered MAPK pathway.Consequently,the MAPK pathway regulated the expression of cytokines and chemokines,which promoted the development of cytokine storm.Importantly,Meplazumab could effectively inhibit viral entry and inflammation caused by SARS-CoV-2 and its variants.Therefore,our findings provided a new perspective for severe COVID-19-related pathogenesis.Furthermore,the validated universal receptor for SARS-CoV-2 and its variants can be targeted for COVID-19 treatment. | Jiejie Geng Liang Chen Yufeng Yuan Ke Wang Youchun Wang Chuan Qin Guizhen Wu Ruo Chen Zheng Zhang Ding Wei Peng Du Jun Zhang Peng Lin Kui Zhang Yongqiang Deng Ke Xu Jiangning Liu Xiuxuan Sun Ting Guo Xu Yang Jiao Wu Jianli Jiang Ling Li Kun Zhang Zhe Wang Jing Zhang Qingguo Yan Hua Zhu Zhaohui Zheng Jinlin Miao Xianghui Fu Fengfan Yang Xiaochun Chen Hao Tang Yang Zhang Ying Shi Yumeng Zhu Zhuo Pei Fei Huo Xue Liang Yatao Wang Qingyi Wang Wen Xie Yirong Li Mingyan Shi Huijie Bian Ping Zhu Zhi-Nan Chen | 2021 | Signal Transduction and Targeted Therapy2021，6，10： | 6 |
| 20 | Comparative studies on zooplankton community between the sea surface microlayer and the subsurface microlayer in Daya Bay, China显示文摘Characteristics of the zooplankton community inhabiting the sea surface microlayer (SM) and the sub-surface microlayer (SSM) are compared at six sampling stations in Daya Bay, near Shenzhen City of China during 2 cruises in 1999. This is the first study on zooplankton community in the SM in China. Results show that protozoans and nauplii are the most dominant components, accounting for 80.71% (SM) and 89.15% (SSM) of the total zooplankton in the average abundance, respectively. The densities of copepods (adult + copepodid) are higher in the SSM than in the SM. The size-frequency distributions indicate that the frequency of micro-zooplankton (<0.2 mm) is higher in the SM (0.8235, n=290) than in the SSM (0.6768, n=306). Enrichment phenomenon of zooplankton is detected in the SM at the sampling stations excluding two stations near nuclear power plants (NPP). The enrichment factor is from 1.516 to 3.364 with the average value of 2.267. The SM zooplankton community structure revealed in the present study is quite different from previous investigations in the Bay. Typical sea water characteristics such as turbidity, biological oxygen demand (BOD), chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP) and chlorophyll a (Chl-a) indicate that the water quality is poorer in the SM than in the SSM. | YANG Yufeng | 2005 | Progress in Natural Science:Materials International2005，15，8： | 6 |
