| 1 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 2 | Inhibitory Activity of Honeysuckle Extracts against Influenza A Virus In Vitro and In Vivo显示文摘Honeysuckle has been used in the treatment of influenza virus infection for thousands of years in China.However,its main active components and the functional mechanisms remain to be elucidated.Here,four honeysuckle extracts,including acids extract,flavonoids extract,total extract and acids-flavonoids mixture,were prepared to clarify the main active antiviral components.The cytopathic effect reduction assay showed that all the four extracts inhibited the replication of influenza viruses H1N1,H3N2 and the oseltamivir-resistant mutant strain H1N1-H275Y.The acids-flavonoids mixture had the strongest inhibitory effects in vitro with EC_(50) values of 3.8,4.1,and >20 lg/m L against H1N1,H3N2 and H1N1-H275Y,respectively,showing competitive antiviral activity with oseltamivir and ribavirin.Honeysuckle acids extract also showed the most significant antiviral activity in vivo.Oral administration of the acids extract at a dosage of 600 mg/kg/d effectively alleviated viral pneumonia,maintained body weight and improved the survival rate to 30% of the mice infected with a lethal dose of H1N1.The results of time-of-drug addition experiment and neuraminidase (NA) inhibition assay showed that honeysuckle extracts had a broad-spectrum inhibitory effect against influenza virus NAs.The flavonoid extract showed the strongest inhibitory effect on the NA of influenza virus H7N9 with an IC_(50) of 24.7 lg/m L.These results suggested that these extracts might exert their antiviral activity by suppressing the release of influenza viruses.Briefly,our findings demonstrate that acids and flavonoids extracts of honeysuckle are the major antiviral active components,and the acids extract has the potential to be developed into an antiviral agent against influenza virus,especially for oseltamivirresistant viruses. | Mengwei Li Yuxu Wang Jing Jin Jie Dou Qinglong Guo Xue Ke Changlin Zhou Min Guo | 2021 | Virologica Sinica2021，36，3： | 11 |
| 3 | Digital Earth 2020:towards the vision for the next decade显示文摘This position paper is the outcome of a brainstorming workshop organised by the International Society for Digital Earth(ISDE)in Beijing in March 2011.It argues that the vision of Digital Earth(DE)put forward by Vice-President Al Gore 13 years ago needs to be re-evaluated in the light of the many developments in the fields of information technology,data infrastructures and earth observation that have taken place since.The paper identifies the main policy,scientific and societal drivers for the development of DE and illustrates the multi-faceted nature of a new vision of DE grounding it with a few examples of potential applications.Because no single organisation can on its own develop all the aspects of DE,it is essential to develop a series of collaborations at the global level to turn the vision outlined in this paper into reality. | Max Craglia Kees de Bie Davina Jackson Martino Pesaresi Gabor Remetey-Fulopp Changlin Wang Alessandro Annoni Ling Bian Fred Campbell Manfred Ehlers John van Genderen Michael Goodchild Huadong Guo Anthony Lewis Richard Simpson Andrew Skidmore Peter Woodgate | 2012 | International Journal of Digital Earth2012，5，1： | 8 |
| 4 | Ecological provinces of spring phytoplankton in the Yellow Sea:species composition显示文摘Phytoplanktonic ecological provinces of the Yellow Sea(31.20°–39.23°N, 121.00°–125.16°E) is derived in terms of species composition and hydrological factors(temperature and salinity). 173 samples were collected from 40 stations from April 28 to May 18, 2014, and a total of 185 phytoplanktonic algal species belonging to 81 genera of 7phyla were identified by Uterm?hl method. Phytoplankton abundance in surface waters is concentrated in the west coast of Korean Peninsula and Korea Bay, and communities in those areas are mainly composed of diatoms and cyanobacteria with dominant species of Cylindrotheca closterium, Synechocystis pevalekii, Chroomonas acuta,Paralia sulcata, Thalassiosira pacifica and Karenia mikimotoi, etc. The first ten dominant species of the investigation area are analyzed by multidimensional scaling(MDS) and cluster analysis, then the Yellow Sea is divided into five provinces from Province I(P-I) to Province V(P-V). P-I includes the coastal areas near southern Liaodong Peninsula, with phytoplankton abundance of 35 420×10~3–36 163×10~3 cells/L and an average of 35 791×10~3 cells/L, and 99.84% of biomass is contributed by cyanobacteria. P-II is from Shandong Peninsula to Subei coastal area. Phytoplankton abundance is in a range of 2×10~3–48×10~3 cells/L with an average of 24×10~3cells/L, and 63.69% of biomass is contributed by diatoms. P-III represents the Changjiang(Yangtze River) Diluted Water. Phytoplankton abundance is 10×10~3–37×10~3 cells/L with an average of 24×10~3 cells/L, and 73.14% of biomass is contributed by diatoms. P-IV represents the area affected by the Yellow Sea Warm Current.Phytoplankton abundance ranges from 6×10~3 to 82×10~3 cells/L with an average of 28×10~3 cells/L, and 64.17% of biomass is contributed by diatoms. P-V represents the cold water mass of northern Yellow Sea. Phytoplankton abundance is in a range of 41×10~3–8 912×10~3 cells/L with an average of 1 763×10~3 cells/L, and 89.96% of biomass is contributed by diatoms. Overall, structures of phytoplankton community in spring are quite heterogeneous in different provinces. Canonical correspondence analysis(CCA) result illustrates the relationship between dominant species and environmental factors, and demonstrates that the main environmental factors that affect phytoplankton distribution are nitrate, temperature and salinity. | ZHANG Shan LENG Xiaoyun FENG Yuanyuan DING Changlin YANG Yang WANG Jing WANG Houjie SUN Jun | 2016 | Acta Oceanologica Sinica2016，35，8： | 7 |
| 5 | Coagulation factors VII, IX and X are effective antibacterial proteins against drug-resistant Gram-negative bacteria显示文摘Infections caused by drug-resistant“superbugs”pose an urgent public health threat due to the lack of effective drugs;however, certain mammalian proteins with intrinsic antibacterial activity might be underappreciated. Here, we reveal an antibacterial property against Gram-negative bacteria for factors VII, IX and X, three proteins with well-established roles in initiation of the coagulation cascade. These factors exert antibacterial function via their light chains (LCs). Unlike many antibacterial agents that target cell metabolism or the cytoplasmic membrane, the LCs act by hydrolyzing the major components of bacterial outer membrane, lipopolysaccharides, which are crucial for the survival of Gram-negative bacteria. The LC of factor VII exhibits in vitro efficacy towards all Gram-negative bacteria tested, including extensively drug-resistant (XDR) pathogens, at nanomolar concentrations. It is also highly effective in combating XDR Pseudomonas aeruginosa and Acinetobacter baumannii infections in vivo. Through decoding a unique mechanism whereby factors VII, IX and X behave as antimicrobial proteins, this study advances our understanding of the coagulation system in host defense, and suggests that these factors may participate in the pathogenesis of coagulation disorder-related diseases such as sepsis via their dual functions in blood coagulation and resistance to infection. Furthermore, this study may offer new strategies for combating Gram-negative “superbugs”. | Jinwu Chen Xiaojie Li Ling Li Ting Zhang Qing Zhang Fangming Wu Diyue Wang Hongze Hu Changlin Tian Dongsheng Liao Liang Zhao Danxia Song Yongyun Zhao Chuanfang Wu Xu Song | 2019 | Cell Research2019，29，9： | 6 |

| 7 | Enhancement of innate immune system in monocot rice by transferring the dicotyledonous elongation factor Tu receptor EFR显示文摘The elongation factor Tu(EF-Tu) receptor(EFR) in cruciferous plants specifically recognizes the N-terminal acetylated elf18 region of bacterial EF-Tu and thereby activates plant immunity.It has been demonstrated that Arabidopsis EFR confers broad-spectrum bacterial resistance in the EFR transgenic solanaceous plants.Here,the transgenic rice plants(Oryza sativa L.ssp.japonica cv.Zhonghua 17) and cell cultures with constitutive expression of AtEFR were developed to investigate whether AtEFR senses EF-Tu and thus enhances bacterial resistance in the monocot plants.We demonstrated that the Xanthomonas oryzae-derived elf18 peptide induced oxidative burst and mitogen-activated protein kinase activation in the AtEFR transgenic rice cells and plants,respectively.Pathogenesis-related genes,such as OsPBZ1,were upregulated dramatically in transgenic rice plant and cell lines in response to elf18 stimulation.Importantly,pretreatment with elf18 triggered strong resistance to X.oryzae pv.oryzae in the transgenic plants,which was largely dependent on the AtEFR expression level.These plants also exhibited enhanced resistance to rice bacterial brown stripe,but not to rice fungal blast.Collectively,the results indicate that the rice plants with heterologous expression of AtEFR recognize bacterial EF-Tu and exhibit enhanced broad-spectrum bacterial disease resistance and that pattern recognition receptor-mediated immunity may be manipulated across the two plant classes,dicots and monocots. | Fen Lu Huiqin Wang Shanzhi Wang Wendi Jiang Changlin Shan Bin Li Jun Yang Shiyong Zhang Wenxian Sun | 2015 | Journal of Integrative Plant Biology2015，57，7： | 6 |

| 11 | Somatosensory Neuron Typing with High-Coverage Single-Cell RNA Sequencing and Functional Analysis显示文摘Different physical and chemical stimuli are detected by the peripheral sensory receptors of dorsal root ganglion(DRG) neurons, and the generated inputs are transmitted via afferent fibers into the central nervous system. The gene expression profiles of DRG neurons contribute to the generation, transmission, and regulation of various somatosensory signals. Recently, the single-cell transcriptomes, cell types, and functional annotations of somatosensory neurons have been studied. In this review,we introduce our classification of DRG neurons based on single-cell RNA-sequencing and functional analyses, and discuss the technical approaches. Moreover, studies on the molecular and cellular mechanisms underlying somatic sensations are discussed. | Changlin Li Sashuang Wang Yan Chen Xu Zhang | 2018 | Neuroscience Bulletin2018，34，1： | 4 |
| 12 | Mechanism and effect of Shijueming (Concha Haliotidis) on serum calcium in spontaneously hypertensive rats显示文摘OBJECTIVE: To observe the impact of Shijueming (Concha Haliotidis) on spontaneously hypertensive rats via blood pressure, serum calcium, vascular smooth muscle membrane L-type calcium channel α1 C subunit (CaL-α1C), plasma membrane calcium-ATPase (PMCA) mRNA expression, and the L-type calcium channel in vascular smooth muscle cells. METHODS:Twelve-week-old male rats with spontaneous hypertension were divided into three groups: a Shijueming (Concha Haliotidis) group (group 1), a nifedipine group (group 2), and a distilled water group (group 3). All were given a four-week treatment. Blood pressure and dissociative serum calcium were examined before treatment. Blood pressure was taken every week during treatment. Atomic absorption spectrometry was used to examine dissociative serum calcium. Re-verse transcription-polymerase chain reaction was used to examine the expression of CaL-α1C and PM-CA1 mRNA. The patch clamp technique was used to examine the electrophysiological characteristics of the vascular smooth muscle cell calcium channels. RESULTS: After treatment, blood pressure of the Shijueming (Concha Haliotidis) group lowered but not significantly (P>0.05). Blood pressure of the nifedipine group lowered significantly (P<0.05). Blood pressure of the distilled water group remained high. The concentration of serum calcium in the Shijueming (Concha Haliotidis) and the distilled water groups lowered (P<0.05). Expression of CaL-α1C mRNA in the nifedipine group decreased compared with the distilled water group (P<0.01). There was the decreasing trend in the Shijueming (Concha Haliotidis) group, but it was not statistically significant. Shijueming (Concha Haliotidis) also had effects on the expression of PMCA1 mRNA but with- out statistical significance. However, there was a significant decreasing effect on vascular smooth muscle cell I Ca-L flow. CONCLUSION: This study indicated that Shijueming (Concha Haliotidis) could increase serum calcium and decrease blood pressure. It may work by influencing calcium channels, expression of PMCA1 mRNA, and regulating ion calcium channels and calcium-ATPase. | Chao Chen Changlin Zhao Xuejun Wang Weili Li Xiaoyin Chen | 2013 | Journal of Traditional Chinese Medicine2013，33，3： | 4 |
| 13 | Neuro-protective effects of CNTF on hippocampal neurons via an unknown signal transduction pathway显示文摘In our previous study, we proposed that there may be an unknown pathway in the upper stream of the known signal transduction pathway of Ciliary neurotrophic factor (CNTF) that mediates the neuro-protective function of CNTF. In the present experiment, we observed that the neuro-protective function of the non-classic signal transduction path- way in a L-NMDA (a glutamic acid ion type receptor atagonist) induced hippocampal neuron injury model, using primary culture rat hippocampal neurons, con- tinuous photography and gp130 immunohistochemi- cal assay. The results showed that L-NMDA induced injurious reaction of hippocampal neurons, and CNTF was able to inhibit the toxic action of L-NMDA on hippocampal neurons. Additionally, when JAK/STATs in the known classic signal transduction pathway of CNTF were blocked by PTPi-2, the protective effect of CNTF against L-NMDA injury still existed. L-NMDA caused a rapid increase in the concentration of hip- pocampal intracellular free [Ca2+]i. CNTF was able to attenuate L-NMDA-induced elevation of [Ca2+]i, and blocking JAK/STATs in the known classic signal trans- duction pathway of CNTF did not affect L-NMDA- induced elevation of [Ca2+]i, indicating that, apart from the known classic signal transduction pathway, there may be some other transduction pathways for CNTF to exert the protective effect on hippocampal neurons, and this pathway is related to [Ca2+]. | LI Ping WANG Zongwen YAN Jin Li Zhaoshen JIANG Chunlei NI Xin YANG Yongji LIU Fang LU Changlin | 2006 | Chinese Science Bulletin2006，51，1： | 4 |
| 14 | Vertical motions of tide gauge stations near the Bohai Sea and Yellow Sea显示文摘A modified Gauss-Markov model with weighted constraints was constructed by combining satellite altimeter and tide gauge records. Vertical motion rates of nine tide gauge stations around the Bohai Sea and Yellow Sea are estimated. This is the first time systematic estimates have been derived in this region. Downward trends were seen at the six tide gauge stations located at Tanggu, Longkou, Laohutan, Bayuquan, Xiaochangshan, and Yantai; with vertical motion rates of-1.82±0.50,-1.65±0.46,-0.88±0.42,-0.58±0.62,-0.13±0.43, and-0.01±0.43 mm/yr, respectively. Upward trends were seen at the three tide gauge stations located at Qinhuangdao, Huludao and Chengshantou; with vertical motion rates of 1.12±0.46, 0.55±0.49 and 0.26±0.44 mm/yr, respectively. There was significant subsidence in Tanggu and Longkou, and a rising trend in Qinhuangdao. According to our results, the rate of sea level rise calculated from these tide gauge records can be improved using a more accurate measurement of the land elevation accounting for lifting or subsidence. The model derived can be used to estimate vertical motions of tide gauge stations, and can be widely applied to revise the benchmark levels of tide gauges. | LIU ShouHua CHEN ChangLin LIU KeXiu MU Lin WANG Hui WU XinRong ZHANG JianLi DUAN XiaoFeng GAO Jia | 2015 | Science China Earth Sciences2015，58，12： | 4 |
| 15 | Obtaining digital elevation data in different terrain and physiognomy regions with spaceborne InSAR and its application analysis显示文摘Synthetic Aperture Radar Interferometry (for short, InSAR) is a new kind of earth observation technology, which has obtained great development in recent ten years and has a great development potential and successful future. In this note, three typical regions with different physiognomies and terrains have been selected as study regions to extract their Digital Elevation Model (OEMs). Compared with the existing 1 : 250000 DEM and by analyzing their results, we have obtained its accuracy and applicable scopes. The results show that in the region (plains, mountains or highlands) with dry surface and sparse vegetation, because of the better correlatability of images, the DEM obtained by InSAR is evidently better than the existing 1 : 250000 DEM and the accuracy can reach 4-6m; in the thick-vegetation-covering region, correlatability between images descends and the accuracy of InSAR DEM can only reach about 30 m worse than its existing 1:250000 DEM; in the middle covering field, the accuracy of InSAR DEM | SHAN Xinjian SONG Xiaoyu LIU Jiahang WANG Changlin | 2002 | Chinese Science Bulletin2002，47，10： | 3 |

| 17 | Observed subsurface eddies near the Vietnam coast of the South China Sea显示文摘In this study, subsurface eddies near the Vietnam coast of the South China Sea were observed with in situ observations, including Argo, CTD, XBT and some processed and quality controlled data. Based on temperature profiles from four Argo floats near the coast of Vietnam, a subsurface warm eddy was identified in spring and summer. The multi-year Argo and Global Temperature and Salinity Profile Programme(GTSPP) data were merged on a seasonal basis based on the data interpolating variational analysis(DIVA) method to reconstruct the three-dimensional temperature structure. There is a warm eddy in the central subsurface at 12.5°N, 111°E below300 m depth in spring, which does not exist in autumn and is weak in winter and summer. From CSIRO Atlas of Regional Seas(CARS) and Generalized Digital Environment Model(GDEM) reanalysis data, this subsurface warm eddy is also verified in spring. | Bo Song Huizan Wang Changlin Chen Ren Zhang Senliang Bao | 2019 | Acta Oceanologica Sinica2019，38，4： | 3 |
| 18 | Sugars promote graft union development in the heterograft of cucumber onto pumpkin显示文摘The use of heterografts is widely applied for the production of several important commercial crops,but the molecular mechanism of graft union formation remains poorly understood.Here,cucumber grafted onto pumpkin was used to study graft union development,and genome-wide tempo-spatial gene expression at the graft interface was comprehensively investigated.Histological analysis suggested that resumption of the rootstock growth occurred after both phloem and xylem reconnection,and the scion showed evident callus production compared with the rootstock 3 days after grafting.Consistently,transcriptome data revealed specific responses between the scion and rootstock in the expression of genes related to cambium development,the cell cycle,and sugar metabolism during both vascular reconnection and healing,indicating distinct mechanisms.Additionally,lower levels of sugars and significantly changed sugar enzyme activities at the graft junction were observed during vascular reconnection.Next,we found that the healing process of grafted etiolated seedlings was significantly delayed,and graft success,xylem reconnection,and the growth of grafted plants were enhanced by exogenous glucose.This demonstrates that graft union formation requires the correct sugar content.Furthermore,we also found that graft union formation was delayed with a lower energy charge by the target of rapamycin(TOR)inhibitor AZD-8055,and xylem reconnection and the growth of grafted plants were enhanced under AZD-8055 with exogenous glucose treatment.Taken together,our results reveal that sugars play a positive role in graft union formation by promoting the growth of cucumber/pumpkin and provide useful information for understanding graft union healing and the application of heterografting in the future. | Li Miao Qing Li Tian-shu Sun Sen Chai Changlin Wang Longqiang Bai Mintao Sun Yansu Li Xing Qin Zhonghua Zhang Xianchang Yu | 2021 | Horticulture Research2021，8，1： | 3 |
| 19 | Highly sensitive,sub-microsecond polymer photodetectors for blood oxygen saturation testing显示文摘Bottom surface of active layers and interface of indium tin oxide(ITO)electrodes and active layers play a crucial role in determining the performance of polymer photodetectors with photomultiplication(PM-PPDs).The interfacial trapped electron distribution closing to ITO electrodes will determine spectral response range and external quantum efficiency(EQE)of PMPPDs.The bottom interface is more sensitive than top interface when light is coming from the ITO side,and the larger density of generated charge on the bottom interfaces will induce interfacial band more bending for efficient charge tunneling injection.Highly sensitive and sub-microsecond PM-PPDs are achieved with PMBBDT:Y6(100:7,w/w)as active layers under forward bias,yielding EQE of 18,700%at 320 nm,21,700%at 600 nm and 16,400%at 810 nm under a bias of 7 V,respectively,as well as fast response time of 79μs.The high EQE of the PM-PPDs is attributed to efficient hole tunneling injection from ITO electrode under forward bias.The electron traps closing to ITO electrode will be quickly filled up when light is coming from ITO side,leading to interfacial band more bending for hole tunneling injection.Importantly,the PM-PPDs is performed to measure heart rate(HR)and blood oxygen saturation(SpO_(2)),and the measured data by the PM-PPDs are very similar with those obtained by commercial photodetectors. | Zijin Zhao Baiqiao Liu Changlin Xie Yao Ma Jian Wang Ming Liu Kaixuan Yang Yunhua Xu Jian Zhang Weiwei Li Liang Shen Fujun Zhang | 2021 | Science China Chemistry2021，64，8： | 2 |
