| 4 | Study on regional material flow analysis of Chengyang District in Qingdao显示文摘Base on the framework of material flow analysis (MFA) proposed by Eurostat, this paper collected relateddata and conducted a regional MFA for the Chengyang District in Qingdao. The indicators such as Direct Material Input(DMI), Direct Material Consumption (DMC) and Exports are calculated or estimated for the period of year 1995through 2004. Several derivable indicators defining direct material productivity and material intensity are also evaluatedand some valuable conclusions were drawn. DMI in absolute number increased from about 1645.9 kilotons in 1995 toabout 8052.5 kilotons in 2004. Imports contribute to about 47 to 69% of DMI, and the biggest component of imports isfossil fuel that approximately accounts for 50% of imports. DMI per capita of Chengyang District increased rapidly andreached 17.4 tons in 2004. Compared with other five economies studied by WRI, material consumption intensity ofChengyang District is significantly lower than developed countries, which indicates that Chengyang District is still in adevelopment stage. The direct material productivity (actual GDP per DMI) increased 59.1% from 1995 to 2004 and hasbeen higher than either of studies in China, which indicates efficiency of resources utilization has improved obviously inChengyang District. But there was significant increase in material input in the last decade, which shows that rapidincrease of economy is highly dependent on requirement and consumption of natural resources. Therefore, in order topromote the sustainability, it is essential to develop circular economy and improve utilization efficiency of resources. | Zhou Zhenfeng Sun Yinglan Wang Jun | 2006 | Ecological Economy2006，2，1： | 5 |
| 5 | Subtyping of type A influenza by sequencing the variable regions of HA gene specifically amplified with RT-PCR显示文摘The outbreak of a novel influenza A(H1N1) virus across the globe poses a threat to human health.It is of paramount importance to develop a rapid,reliable and inexpensive diagnostic procedure.Based on the bioinformatic information from public database,primers specific for influenza A virus surface protein haemagglutinin(HA) of several subtypes(including H1,H2,H3,H5,H7 and H9) were designed.Primer-specific PCR products were subjected to sequencing for accurately distinguishing H1 and H3 subtypes from others.This sequencing-based detection method will not only be applied to rapid detection and simultaneous subtype identification of new influenza A virus H1N1,but also provide the strategies to monitor other new types ofinfluenza virus with explosive potential. | YAN An DING GuoHui ZHOU ZhenFeng DONG Hui ZHANG YaKun ZHU Lei HE YunGang ZHANG GuoQing LI YiXue SUN Bing HUANG Zhong LAN Ke JIN Li WANG HongYan WANG XiaoNing YANG Zhong ZHONG Yang DAI JianXin GUO YaJun WANG Hao CHE XiaoYan WU Fan YUAN ZhenGan ZHANG Xi CAO ZhiWei ZHOU XiaoNong ZHOU JiaHai MA ZhiYong TONG GuangZhi ZHAO GuoPing JIN WeiRong XIONG Hui | 2009 | Chinese Science Bulletin2009，54，13： | 3 |

| 7 | Winter soil CO_2 efflux in two contrasting forest ecosystems on the eastern Tibetan Plateau, China显示文摘Significant CO_2 fluxes from snow-covered soils occur in cold biomes. However, little is known about winter soil respiration on the eastern Tibetan Plateau of China. We therefore measured winter soil CO_2 fluxes and estimated annual soil respiration in two contrasting coniferous forest ecosystems(a Picea asperata plantation and a natural forest).Mean winter soil CO_2 effluxes were 1.08 lmol m^-2s^-1in the plantation and 1.16 lmol m^-2s^-1in the natural forest.These values are higher than most reported winter soil CO_2 efflux values for temperate or boreal forest ecosystems.Winter soil respiration rates were similar for our two forest ecosystems but mean soil CO_2 efflux over the growing season was higher in the natural forest than in the plantation. The estimated winter and annual soil effluxes for the natural forest were 176.3 and 1070.3 g m^-2, respectively, based on the relationship between soil respiration and soil temperature,which were 17.2 and 9.7 % greater than their counterparts in the plantation. The contributions of winter soil respiration to annual soil efflux were 15.4 % for the plantation and 16.5 %for the natural forest and were statistically similar. Our results indicate that winter soil CO_2 efflux from frozen soils in the alpine coniferous forest ecosystems of the eastern Tibetan Plateau was considerable and was an important component of annual soil respiration. Moreover, reforestation(natural coniferous forests were deforested and reforested with P. asperata plantation) may reduce soil respiration by reducing soil carbon substrate availability and input. | Zhenfeng Xu Feifei Zhou Huajun Yin Qing Liu | 2015 | Journal of Forestry Research2015，26，3： | 2 |

| 9 | Enhanced nitrogen removal and microbial analysis in partially saturated constructed wetland for treating anaerobically digested swine waste water显示文摘Nitrogen removal of wastewater containing high-strength ammonium by the constructed wetlands (CWs) has been paid much attention. In this study, the ability of a partially saturated CW to treat anaerobically-digested decentralized swine wastewater under varying operating parameters from summer to winter was investigated. The partially saturated CW achieved better NH4^+-N and TN removal by tidal flow than intermittent flow. With surface loading rates of 0.108, 0.027, and 0.029 kg/(m^2·d) for COD, NH4^+-N, and TN, the partially saturated CW by tidal operation achieved corresponding removal efficiencies of 85.94%, 61.20%, and 57.41%, respectively, even at 10℃. When the rapid-adsorption of NH4^+-N and the bioregeneration of zeolites reached dynamically stable, the simultaneous nitrification and denitrification in the aerobic zeolite layer was observed and accounted for 58.82% of the total denitrification of CW. The results of Illumina high-throughput sequencing also indicated that nitnfiers (Nitrospira and Rhizomicrobiurri) and denitrifiers (Rhodanobacter and Thauera) simultaneously existed in the zeolite layer. The dominant existence of versatile organic degraders and nitrifiers/denitrifiers in the zeolite layer was related to the removal of most COD and nitrogen in this zone. The contribution of the possible nitrogen removal pathways in the CW was as follows: nitrification-denitrification (86.55%)>substrate adsorption (11.70%)>plant uptake (1.15%)>microbial assimilation (0.60%). | Zhenfeng Han Ying Miao Jing Dong Zhiqiang Shen Yuexi Zhou Shan Liu Chunping Yang | 2019 | Frontiers of Environmental Science & Engineering2019，13，4： | 2 |

| 12 | ACE2 expression is regulated by AhR in SARS-CoV-2-infected macaques显示文摘During the current outbreak of coronavirus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),more than 115 million people have been infected,and 2.5 million have died.1,2 Despite such great harm to human health,the pathogenesis of COVID-19 remains unclear.As the first step in the pathogenetic process,viral entry is mediated by the binding of the SARS-CoV-2 surface spike(S)protein to angiotensin-converting enzyme 2(ACE2)on host cells,such as lung epithelial cells.As an alternative to S protein-blocking strategies,manipulating host cell ACE2 expression may exert an inhibitory effect on SARS-CoV-2 infection.However,the molecular mechanism regulating ACE2 expression remains unclear. | Jiadi Lv Pin Yu Zhenfeng Wang Wei Deng Linlin Bao Jiangning Liu Fengli Li Qiangqiang Zhu Nannan Zhou Qi Lv Guanpeng Wang Shunyi Wang Yabo Zhou Jiangping Song Wei-Min Tong Yuying Liu Chuan Qin Bo Huang | 2021 | Cellular & Molecular Immunology2021，18，5： | 1 |
| 13 | Development of a New Welding Material for Arc Welding of As-cast Ferritic Ductile Iron显示文摘Using the nickel welding wire, the effect of alloying elements on the chilling tendency of partial fusion zone (PFZ) of arc-welded ferritic ductile iron and the mechanical properties of weld metal have been systematically studied. On this basis a new nickel electrode for arc welding of ferritic ductile iron (QT400-17) is developed for the first time. The mechanical properties of its weld metal can match those of ferritic ductile iron. The width of carbide layer (WCL) in PFZ is significantly decreased, the welded joint has excellent machinability and the weid metal has high hot cracking | Sun, Daqian Zhou, Zhenfeng Luan, Jingfei

| 15 | SARS-CoV-2 treatment effects induced by ACE2-expressing microparticles are explained by the oxidized cholesterolincreased endosomal pH of alveolar macrophages显示文摘Exploring the cross-talk between the immune system and advanced biomaterials to treat SARS-CoV-2 infection is a promising strategy.Here,we show that ACE2-overexpressing A549 cell-derived microparticles(AO-MPs)are a potential therapeutic agent against SARS-CoV-2 infection.Intranasally administered AO-MPs dexterously navigate the anatomical and biological features of the lungs to enter the alveoli and are taken up by alveolar macrophages(AMs).Then,AO-MPs increase the endosomal pH but decrease the lysosomal pH in AMs,thus escorting bound SARS-CoV-2 from phago-endosomes to lysosomes for degradation.This pH regulation is attributable to oxidized cholesterol,which is enriched in AO-MPs and translocated to endosomal membranes,thus interfering with proton pumps and impairing endosomal acidification.In addition to promoting viral degradation,AO-MPs also inhibit the proinflammatory phenotype of AMs,leading to increased treatment efficacy in a SARS-CoV-2-infected mouse model without side effects.These findings highlight the potential use of AO-MPs to treat SARS-CoV-2-infected patients and showcase the feasibility of MP therapies for combatting emerging respiratory viruses in the future. | Zhenfeng Wang Jiadi Lv Pin Yu Yajin Qu Yabo Zhou Li Zhou Qiangqiang Zhu Shunshun Li Jiangping Song Wei Deng Ran Gao Yuying Liu Jiangning Liu Wei-Min Tong Chuan Qin Bo Huang | 2022 | Cellular & Molecular Immunology2022，19，2： | 1 |

| 17 | Step-wise CAG@PLys@PDA-Cu^(2+)modification on micropatterned nanofibers for programmed endothelial healing显示文摘Native-like endothelium regeneration is a prerequisite for material-guided small-diameter vascular regeneration.In this study,a novel strategy is proposed to achieve phase-adjusted endothelial healing by step-wise modification of parallel-microgroove-patterned(i.e.,micropatterned)nanofibers with polydopamine-copper ion(PDA-Cu^(2+))complexes,polylysine(PLys)molecules,and Cys-Ala-Gly(CAG)peptides(CAG@PLys@PDA-Cu^(2+)).Using electrospun poly(L-lactide-co-caprolactone)random nanofibers as the demonstrating biomaterial,step-wise modification of CAG@PLys@PDA-Cu^(2+)significantly enhanced substrate wettability and protein adsorption,exhibited an excellent antithrombotic surface and outstanding phase-adjusted capacity of endothelium regeneration involving cell adhesion,endothelial monolayer formation,and the regenerated endothelium maturation.Upon in vivo implantation for segmental replacement of rabbit carotid arteries,CAG@PLys@PDA-Cu^(2+)modified grafts(2 mm inner diameter)with micropatterns on inner surface effectively accelerated native-like endothelium regeneration within 1 week,with less platelet aggregates and inflammatory response compared to those on non-modified grafts.Prolonged observations at 6-and 12-weeks post-implantation demonstrated a positive vascular remodeling with almost fully covered endothelium and mature smooth muscle layer in the modified vascular grafts,accompanied with well-organized extracellular matrix.By contrast,non-modified vascular grafts induced a disorganized tissue formation with a high risk of thrombogenesis.In summary,step-wise modification of CAG@PLys@PDA-Cu^(2+)on micropatterned nanofibers can significantly promote endothelial healing without inflicting thrombosis,thus confirming a novel strategy for developing functional vascular grafts or other blood-contacting materials/devices. | Bingcheng Yi Boya Zhou Zhenfeng Song Lei Yu Wenbo Wang Wei Liu | 2023 | Bioactive Materials2023，，7： | 1 |
| 18 | Airway administration of bisphosphate and dexamethasone inhibits SARS-CoV-2 variant infection by targeting alveolar macrophages显示文摘Dear Editor,Alveolar macrophages(AMs)are among the first immune cells to encounter SARS-CoV-2 during an infection due to their abundant numbers and physical location in the lungs.Thus,the reaction of AMs to SARS-CoV-2 has a profound impact on the outcome of the infection.In most cases,AMs can release cytokines and prime adaptive T-and B-cell immune responses to resolve the infection. | Zhenfeng Wang Yabo Zhou Linlin Bao Dan Li Jiadi Lv Dianheng Wang Shunshun Li Jiangning Liu Chuan Qin Wei-Min Tong Bo Huang | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 1 |
