| 1 | pORF5 plasmid protein of Chlamydia trachomatis induces MAPK-mediated pro-inflammatory cytokines via TLR2 activation in THP-1 cells显示文摘Infection with Chlamydia trachomatis induces inflammatory pathologies in the urogenital tract that can lead to infertility and ectopic pregnancy.Pathogenesis of infection has been mostly attributed to excessive cytokine production.However,precise mechanisms on how C.trachomatis triggers this production,and which protein(s) stimulate inflammatory cytokines remains unknown.In the present study,the C.trachomatis pORF5 protein induced tumor necrosis factor alpha(TNF-α),interleukin-1 beta(IL-1β) and interleukin-8(IL-8) in dose-and time-dependent manners in the THP-1 human monocyte cell line.We found that intracellular p38/mitogen-activated protein kinase(MAPK) and extracellular signal-regulated kinase(ERK)/MAPK signaling pathways were required for the induction of TNF-α,IL-1β and IL-8.Blockade of toll-like receptor 2(TLR2) signaling reduced induction levels of TNF-α,IL-8 and IL-1β.We concluded that the C.trachomatis pORF5 protein might contribute to the inflammatory processes associated with chlamydial infections. | ZHOU Hui HUANG QiuLin LI ZhongYu WU YiMou XIE XiaoBing MA KangKang CAO WenJuan ZHOU Zhou LU ChunXue ZHONG GuangMing | 2013 | Science China(Life Sciences)2013，56，5： | 26 |
| 2 | Macrobenthic community structure in the Changjiang Estuary and its adjacent waters in summer显示文摘On the basis of data collected in the summer of 2006 from 27 sampling stations in the Changjiang Estuary and its adjacent waters, the ecological characteristics of macrobenthos and the relationship between the macrobenthos and the environmental factors were studied using hierarchical cluster and non-metric multidimensional scaling (MDS).The biomass, abundance, Shannon-Wiener's and Margalef's indices of the macrobenthos were presented. The results showed that a total of 253 macrobenthic species were found in the research region, and most of them belong to mollusks and polychaetes. The dominant species were Cossurella dimorpha, Eocylichna cylindrella, Episiphon kiaochowwanense, Nassarius semiplicatus, Ocstergrenia variabilis and Sternaspis scutata. The average abundance of the macrobenthos was (313.15±233.4) ind./m2, and the average biomass was (15.2±11.2)g/m2.The distribution patterns of the abundance and biomass of the macrobenthos were similar. The abundance and biomass in the area close to the estuary were lower than those from the area more distant to the estuary; the central part of the research region had higher abundance and biomass than other parts of the research region. In accordance with the results, four macrobenthic communities with distinct spatial differences were identified. The low abundance and biomass in the area close to the estuary should be caused by the high sedimentation rate. The statistical analysis indicated that the depth is the most important factor affecting the distribution of macrobenthos. | MENG Wei LIU Lusan ZHENG Binghui LI Xinzheng LI Zhongyu | 2007 | Acta Oceanologica Sinica2007，26，6： | 15 |

| 4 | The effect of melt overheating on the melt structure transition and solidified structures of Sn-Bi40 alloy显示文摘Evolution of the electrical resistivity of Sn-40wt%Bi melt with time under different overheating temperatures during isothermal experiments has been studied, and the relationship between different melt state, solidification behavior and solidified structure has also been investigated. The results show that the melt structure transition revealed by the abnormal change of resistivity would take place within a certain holding time just when the holding temperature is above a certain critical, and that the higher the temperature above the critical, the shorter the 'incubation period' of the melt structure transition, and the faster the transition speed. The results of solidification experiments suggest that the melt structure transition caused by different holding time at the same temperature can lead to a higher so-lidification undercooling degree, finer grain size and change of microscopic pattern. Further exploration indicates that the solidification undercooling degree can come to a head when the melt is held at the specific temperature for a given time. The functionary mechanism of the phenomena above is also discussed briefly. | CHEN HongSheng ZU FangQiu CHEN Jie ZOU Li DING GuoHua HUANG ZhongYue | 2008 | Science China(Technological Sciences)2008，51，9： | 11 |
| 5 | Phylogenetic and genetic characterization of a 2017 clinical isolate of H7N9 virus in Guangzhou,China during the fifth epidemic wave显示文摘Pathogenic H7N9 influenza viruses continue to pose a public health concern. The H7N9 virus has caused five outbreak waves of human infections in China since 2013. In the present study, a novel H7N9 strain(A/Guangdong/8 H324/2017) was isolated from a female patient with severe respiratory illness during the fifth wave of the 2017 H7N9 epidemic. Phylogenetic analysis showed that the H7N9 viruses collected during the fifth wave belong to two different lineages: the Pearl River Delta lineage and the Yangtze River Delta lineage. The novel isolate is closely related to the Pearl River Delta H7N9 viruses, which were isolated from patients in Guangdong Province. The novel H7N9 isolate has an insertion of three basic amino acids in the cleavage site of hemagglutinin(HA), which may enhance virulence in poultry. The 2017 isolate also possesses an R292 K substitution in the neuraminidase(NA)protein, which confers oseltamivir resistance. This study highlights the pandemic potential of the novel H7N9 virus in mammals;thus, future characterization and surveillance is warranted. | Yongqiang Deng Chunlin Li Jianfeng Han Yingfen Wen Jian Wang Wenxing Hong Xiaofeng Li Zhongyu Liu Qing Ye Jing Li Changshuai Zhou Lei Yu Chengfeng Qin Fuchun Zhang Tao Jiang | 2017 | Science China(Life Sciences)2017，60，12： | 9 |
| 6 | Inhibiting collagen Ⅰ production and tumor cell colonization in the lung via miR-29a-3p loading of exosome-/liposome-based nanovesicles显示文摘The lung is one of the most common sites for cancer metastasis.Collagens in the lung provide a permissive microenvironment that supports the colonization and outgrowth of disseminated tumor cells.Therefore,down-regulating the production of collagens may contribute to the inhibition of lung metastasis.It has been suggested that mi R-29 exhibits effective anti-fibrotic activity by negatively regulating the expression of collagens.Indeed,our clinical lung tumor data shows that mi R-29 a-3 p expression negatively correlates with collagen I expression in lung tumors and positively correlates with patients’outcomes.However,suitable carriers need to be selected to deliver this therapeutic mi RNA to the lungs.In this study,we found that the chemotherapy drug cisplatin facilitated mi R-29 a-3 p accumulation in the exosomes of lung tumor cells,and this type of exosomes exhibited a specific lung-targeting effect and promising collagen down-regulation.To scale up the preparation and simplify the delivery system,we designed a lung-targeting liposomal nanovesicle(by adjusting the molar ratio of DOTAP/cholesterol-mi RNAs to 4:1)to carry mi R-29 a-3 p and mimic the exosomes.This liposomal nanovesicle delivery system significantly down-regulated collagen I secretion by lung fibroblasts in vivo,thus alleviating the establishment of a pro-metastatic environment for circulating lung tumor cells. | Yan Yan Cancan Du Xixi Duan Xiaohan Yao Jiajia Wan Ziming Jiang Zhongyu Qin Wenqing Li Longze Pan Zhuoyu Gu Fazhan Wang Ming Wang Zhihai Qin | 2022 | Acta Pharmaceutica Sinica B2022，12，2： | 7 |

| 8 | The effect of crack tip environment on crack growth behaviour of a low alloy steel at cathodic potentials in artificial seawater显示文摘The environment at crack tip and its effect on the crack growth behaviour of low alloy steel-E690 steel were studied at cathodic potentials in artificial seawater.The results showed that the micro environment at crack tip and crack growth behaviour were related to the electrochemical reactions at crack tip,which were affected by the stress state and applied potentials.The crack tip environment was acidified under cyclic loading,resulting from the crack tip anodic dissolution reaction and corresponding hydrolysis reaction.Because of the hydrogen evolution and the inhibited anodic dissolution inside the crack,the crack tip p H increases as the cathodic potential decreases.The effect of cathodic potentials on the electrochemical reactions caused the variation of the hydrogen content,which influenced the crack growth rate because the crack growth behaviour was controlled by hydrogen embrittlement mechanism.This resulted in a fact that with the negative decrease of potential,the crack growth rate first decreased and then increased,with the minimum rate at-0.75 V.And the crack growth path exhibited transgranular fracture. | Yong Li Zhiyong Liu Endian Fan Zhongyu Cui Jinbin Zhao | 2020 | Journal of Materials Science & Technology2020，54，19： | 5 |
| 9 | Localization and characterization of the hypothetical protein CT440 in Chlamydia trachomatis-infected cells显示文摘The inclusion membrane proteins play potentially important roles in chlamydial biology and pathogenesis.Here we localized and characterized the hypothetical protein CT440 in Chlamydia trachomatis-infected cells.The open reading frame(ORF) encoding the CT440 protein from the C.trachomatis serovar D genome was cloned into the prokaryotic expression vector pGEX-6p and expressed as a glutathione-S-transferase(GST) fusion protein in E.coli XL1-Blue.The CT440 fusion protein was used to immunize mice to raise antigen-specific antibody.After verification by Western blot and immunofluorescence assay(IFA),the specific antibody was used to localize the endogenous CT440 protein and to detect its expression pattern in Chlamydia-infected cells.Cytosolic expression of CT440 in HeLa cells was also carried out to evaluate the effect of the CT440 protein on the subsequent chlamydial infection.The results showed that the hypothetical protein CT440 was localized in the C.trachomatis inclusion membrane,and was detectable 12 h after chlamydial infection.Expression of CT440 in the cytoplasm did not inhibit the subsequent chlamydial infection.In summary,we have identified a new inclusion membrane protein that may be an important candidate for understanding C.trachomatis pathogenesis. | LI ZhongYu HUANG QiuLin SU ShengMei ZHOU Zhou CHEN ChaoQun ZHONG GuangMing WU YiMou | 2011 | Science China(Life Sciences)2011，54，11： | 5 |
| 10 | The SOC1-like gene BoMADS50 is associated with the flowering of Bambusa oldhamii显示文摘Bamboo is known for its edible shoots and beautiful texture and has considerable economic and ornamental value.Unique among traditional flowering plants,many bamboo plants undergo extensive synchronized flowering followed by large-scale death,seriously affecting the productivity and application of bamboo forests.To date,the molecular mechanism of bamboo flowering characteristics has remained unknown.In this study,a SUPPRESSOR OF OVEREXPRESSION OF CONSTANS1(SOC1)-like gene,BoMADS50,was identified from Bambusa oldhamii.BoMADS50 was highly expressed in mature leaves and the floral primordium formation period during B.oldhamii flowering and overexpression of BoMADS50 caused early fl owering in transgenic rice.Moreover,BoMADS50 could interact with APETALA1/FRUITFULL(AP1/FUL)-like proteins(BoMADS 14-1/2,BoMADS15-1/2)in vivo,and the expression of BoMADS50 was signi ficantly promoted by BoMADS14-1,further indicating a synergistic effect between BoMADS50 and BoAP1/FUL-like proteins in regulating B.oldhamii flowering.We also identi fi ed four additional transcripts of BoMADS50(BoMADS50-1/2/3/4)with different nucleotide variations.Although the protein-CDS were polymorphic,they had flowering activation functions similar to those of BoMADS50.Yeast one-hybrid and transient expression assays subsequently showed that both BoMADS50 and BoMADS50-1 bind to the promoter fragment of itself and the SHORT VEGETATIVE PHASE(SVP)-like gene BoSVP,but only BoMADS50-1 can positively induce their transcription.Therefore,nucleotide variations likely endow BoMADS50-1 with strong regulatory activity.Thus,BoMADS50 and BoMADS50-1/2/3/4 are probably important positive flowering regulators in B.oldhamii.Moreover,the functional conservatism and speci ficity of BoMADS50 and BoMADS50-1 might be related to the synchronized and sporadic flowering characteristics of B.oldhamii. | Dan Hou Ling Li Tengfei Ma Jialong Pei Zhongyu Zhao Mengzhu Lu Aimin Wu Xinchun Lin | 2021 | Horticulture Research2021，8，1： | 4 |
| 11 | Efficient full-path optical calculation of scalar and vector diffraction using the Bluestein method显示文摘Efficient calculation of the light diffraction in free space is of great significance for tracing electromagnetic field propagation and predicting the performance of optical systems such as microscopy,photolithography,and manipulation.However,existing calculation methods suffer from low computational efficiency and poor flexibility.Here,we present a fast and flexible calculation method for computing scalar and vector diffraction in the corresponding optical regimes using the Bluestein method.The computation time can be substantially reduced to the sub-second level,which is 105 faster than that achieved by the direct integration approach(~hours level)and 102 faster than that achieved by the fast Fourier transform method(~minutes level).The high efficiency facilitates the ultrafast evaluation of light propagation in diverse optical systems.Furthermore,the region of interest and the sampling numbers can be arbitrarily chosen,endowing the proposed method with superior flexibility.Based on these results,full-path calculation of a complex optical system is readily demonstrated and verified by experimental results,laying a foundation for real-time light field analysis for realistic optical implementation such as imaging,laser processing,and optical manipulation. | Yanlei Hu Zhongyu Wang Xuewen Wang Shengyun Ji Chenchu Zhang Jiawen Li Wulin Zhu Dong Wu Jiaru Chu | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 12 | Therapeutic mechanisms of integrated traditional Chinese and conventional medicine underlying its treatment of precancerous lesions of gastric cancer显示文摘China has a high incidence of gastric cancer. Secondary prevention of gastric cancer is a major public health problem that must be solved urgently. Modern medicine focuses on the pathogenesis of precancerous lesions of gastric cancer(PLGC), and it has been found that there are a variety of abnormal gene expression patterns in PLGC. This study summarizes recent advances in our understanding of the therapeutic mechanisms of PLGC from various clinical studies;this will provide a reference for studying the therapeutic mechanisms of Traditional Chinese Medicine in the treatment of PLGC from the combined points of view of Traditional Chinese and Conventional medicine. | XU Qing WANG Yang LI Zhongyu YAN Jiaxing ZHAO Yingpan WANG Ping WEN Yandong | 2022 | Journal of Traditional Chinese Medicine2022，42，6： | 4 |
| 13 | Interactions between bubble and particles of key minerals of diasporic bauxite through the extended DLVO theory显示文摘The flotation of diasporic bauxite is to separate diaspore(valuable mineral)from aluminosilicate minerals(gangue minerals,mainly including kaolinite,illite and pyrophyllite),and the microscopic interaction force between the two types of minerals and air bubbles determines the separation efficiency.In this paper,based on the extended Derjaguin-Landau-Verwey-Overbeek(DLVO)theory,the van der Waals,electrostatic and hydrophobic interaction between particles of the four minerals mentioned above and air bubbles in collectorless solution were calculated first,and then diaspore and kaolinite were taken as examples to analyze the influence of various factors such as electrolyte concentration,mineral particle size,air bubble size,collector type(dodecylamine hydrochloride(DAH)and sodium oleate(NaOL))and concentration,and pulp pH on the interactions between the particles of valuable mineral and gangue minerals and air bubbles.The results showed that the total extended DLVO interactions between the four minerals and air bubbles were repulsive in most cases in collectorless solution.The increase in electrolyte concentration reduced the interaction force or even changed the direction of the force under certain circumstances.The addition of DAH and NaOL can reduce the adhesion energy barrier of kaolinitebubble and diaspore-bubble respectively.Each type of minerals exhibited a specific interface interaction response with air bubbles in each collector with different pH values.The research results have theoretical guiding significance for the optimization and directional control of diasporic bauxite flotation conditions. | Ningning Zhang Tian Pang Rui Han Songjiang Chen Zhen Li Yuexian Yu Zhongyu Shi Lijun Liu Jinzhou Qu Anning Zhou | 2022 | International Journal of Mining Science and Technology2022，32，1： | 3 |
| 14 | Neutron halo state of ^(13)C显示文摘Angular distributions for the 12C(d, p)13C transfer reactions have been measured at Ed = 11.8 MeV, and compared with those of the DWBA calculations. By means of this comparison, density distributions of the last neutron in the ground state and the first 1/2+ state of 13C are extracted. The properties of these states in 13C have also been studied in the framework of the nonlinear relativistic mean-field theory with NL-SH parameters. It is found that the first l/2+ state in 13C is a neutron halo state shown by both the experimental and theoretical density distributions of the last neutron. | LIU Zuhua, LIN Chengjian, LI Zhichang, ZHANG Huanqiao, CHEN Baoqiu, MA Zhongyu, WU Yuewei, LIU Jiancheng & LI ShuyuanChina Institute of Atomic Energy, Beijing 102413, China | 2001 | Chinese Science Bulletin2001，46，1： | 3 |
| 15 | Simulated photo-degradation of dissolved organic matter in lakes revealed by three-dimensional excitation-emission matrix with regional integration and parallel factor analysis显示文摘Simulated photo-degradation of fluorescent dissolved organic matter(FDOM) in Lake Baihua(BH) and Lake Hongfeng(HF) was investigated with three-dimensional excitationemission matrix(3 DEEM) fluorescence combined with the fluorescence regional integration(FRI),parallel factor(PARAFAC) analysis,and multi-order kinetic models.In the FRI analysis,fulvic-like and humic-like materials were the main constituents for both BH-FDOM and HF-FDOM.Four individual components were identified by use of PARAFAC analysis as humic-like components(C1),fulvic-like components(C2),protein-like components(C3) and unidentified components(C4).The maximum 3 DEEM fluorescence intensity of PARAFAC components C1-C3 decreased by about 60%,70% and 90%,respectively after photo-degradation.The multi-order kinetic model was acceptable to represent the photo-degradation of FDOM with correlation coefficient(Radj2)(0.963-0.998).The photo-degradation rate constants(kn) showed differences of three orders of magnitude,from 1.09 × 10-6 to 4.02 × 10-4 min-1,and half-life of multi-order model(T1/2n)ranged from 5.26 to 64.01 min.The decreased values of fluorescence index(FI) and biogenic index(BI),the fact that of percent fluorescence response parameter of Region I(PⅠ,n) showed the greatest change ratio,followed by percent fluorescence response parameter of Region II(PⅡ,n,while the largest decrease ratio was found for C3 components,and the lowest T1/2n was observed for C3,indicated preferential degradation of protein-like materials/components derived from biological sources during photodegradation.This research on the degradation of FDOM by 3 DEEM/FRI-PARAFAC would be beneficial to understanding the photo-degradation of FD OM in natural environments and accurately predicting the environmental behaviors of contaminants in the presence of FDOM. | Jin Zhang Fanhao Song Tingting Li Kefu Xie Huiying Yao Baoshan Xing Zhongyu Li Yingchen Bai | 2020 | Journal of Environmental Sciences2020，32，4： | 3 |
| 16 | Cycle-by-Cycle Queue Length Estimation for Signalized Intersections Using Multi-Source Data显示文摘In order to estimate vehicular queue length at signalized intersections accurately and overcome the shortcomings and restrictions of existing studies especially those based on shockwave theory,a new methodology is presented for estimating vehicular queue length using data from both point detectors and probe vehicles. The methodology applies the shockwave theory to model queue evolution over time and space. Using probe vehicle locations and times as well as point detector measured traffic states,analytical formulations for calculating the maximum and minimum( residual) queue length are developed. The proposed methodology is verified using ground truth data collected from numerical experiments conducted in Shanghai,China. It is found that the methodology has a mean absolute percentage error of 17. 09%,which is reasonably effective in estimating the queue length at traffic signalized intersections. Limitations of the proposed models and algorithms are also discussed in the paper. | Zhongyu Wang Qing Cai Bing Wu Yinhai Wang Linbo Li | 2015 | Journal of Harbin Institute of Technology(New Series)2015，22，2： | 3 |
| 17 | Mineral Chemistry and Geochemistry of Peridotites from the Zedang and Luobusa Ophiolites, Tibet: Implications for the Evolution of the Neo-Tethys显示文摘We present a new dataset on platinum group elements(PGEs), whole-rock major and trace elements, and mineral chemistry for the peridotites from the Zedang and Luobusa ophiolite suites, Tibet, in an attempt to better constrain the petrogenesis of the Zedang and Luobusa ophiolites and the tectonic evolution of the Neo-Tethys. Plots of chondrite-normalized PGE, PGE vs. Mg#, and PGE vs. Al_2O_3 suggest that the lherzolite and harzburgite from Zedang and Luobusa have similar PGE characteristics. The Zedang and Luobusa peridotites display U-shaped REE patterns and are enriched in some incompatible elements, indicative of melt-rock interaction. The PGE characteristics may be attributed to partial melting and heterogeneous melt-rock interaction. Mineral chemistry and whole rock major and trace elements data suggest that lherzolite and harzburgite from Zedang and Luobusa have similar geochemical properties. On the spinel Mg# vs. Cr# plot, the composition of the Zedang and Luobusa peridotites is consistent with both abyssal and subduction-zone peridotites. This study indicates that the Zedang and Luobusa peridotites have a similar origin and evolution path: they could have originated from a normal mid-ocean ridge environment and got refertilization in a supra-subduction zone setting. | Qiang Li Bin Xia Jianfeng Li Lianze Xia Qiangtai Huang Zhongyu Xia | 2015 | Journal of Earth Science2015，26，6： | 3 |
