| 1 | Active tectonic blocks and strong earthquakes in the continent of China显示文摘The primary pattern of the late Cenozoic to the present tectonic deformation of China is characterized by relative movements and interactions of tectonic blocks. Active tectonic blocks are geological units that have been separated from each other by active tectonic zones. Boundaries between blocks are the highest gradient of differential movement. Most of tectonic activity occurs on boundaries of the blocks. Earthquakes are results of abrupt releases of accumulated strain energy that reaches the threshold of strength of the earth's crust. Boundaries of tectonic blocks are the locations of most discontinuous deformation and highest gradient of stress accumulation, thus are the most likely places for strain energy accumulation and releases, and in turn, devastating earthquakes. Almost all earthquakes of magnitude greater than 8 and 80%-90% of earthquakes of magnitude over 7 occur along boundaries of active tectonic blocks. This fact indicates that differential movements and interactions of active tectonic blocks are the primary mechanism for the occurrences of devastating earthquakes. | ZHANG Peizhen (张培震) DENG Qidong (邓起东) ZHANG Guomin (张国民) MA Jin (马 瑾) GAN Weijun (甘卫军) MIN Wei (闵 伟) MAO Fengying (毛凤英) WANG Qi (王 琪) | 2003 | Science China Earth Sciences2003，46，z2： | 239 |
| 2 | Review on supermolecules as chemical drugs显示文摘Supramolecular medicinal chemistry field has been a quite rapidly developing,increasingly active and newly rising interdiscipline which is the new expansion of supramolecular chemistry in pharmaceu-tical sciences,and is gradually becoming a relatively independent scientific area. Supramolecular drugs could be defined as medicinal supermolecules formed by two or more molecules through non-covalent bonds. So far a lot of supermolecules as chemical drugs have been widely used in clinics. Supermolecules as chemical drugs,i.e. supramolecular chemical drugs or supramolecular drugs,which might have the excellences of lower cost,shorter period,higher potential as clinical drugs for their successful research and development,may possess higher bioavailability,better biocompatibility and drug-targeting,fewer multidrug-resistances,lower toxicity,less adverse effect,and better curative effects as well as safety,and therefore exhibit wide potential application. These overwhelming advan-tages have drawn enormous special attention. This paper gives the definition of supramolecular drugs,proposes the concept of supramolecular chemical drugs,and systematically reviews the recent ad-vances in the research and development of supermolecules,including organic and inorganic complex ones as chemical drugs in the area of antitumor,anti-inflammatory,analgesic,antimalarial,antibacterial,antifungal,antivirus,anti-epileptic,cardiovascular agents and magnetic resonance imaging agents and so on. The perspectives of the foreseeable future and potential application of supramolecules as chemical drugs are also presented. | ZHOU ChengHe GAN LinLing ZHANG YiYi ZHANG FeiFei WANG GuangZhou JIN Lei GENG RongXia | 2009 | Science China Chemistry2009，52，4： | 17 |
| 3 | Advanced Space-based Solar Observatory(ASO-S):an overview显示文摘The Advanced Space-based Solar Observatory(ASO-S)is a mission proposed for the 25 th solar maximum by the Chinese solar community.The scientific objectives are to study the relationships between the solar magnetic field,solar flares and coronal mass ejections(CMEs).Three payloads are deployed:the Full-disk vector Magneto Graph(FMG),the Lyman-αSolar Telescope(LST)and the Hard X-ray Imager(HXI).ASO-S will perform the first simultaneous observations of the photospheric vector magnetic field,non-thermal imaging of solar flares,and the initiation and early propagation of CMEs on a single platform.ASO-S is scheduled to be launched into a 720 km Sun-synchronous orbit in 2022.This paper presents an overview of the mission till the end of Phase-B and the beginning of Phase-C. | Wei-Qun Gan Cheng Zhu Yuan-Yong Deng Hui Li Yang Su Hai-Ying Zhang Bo Chen Zhe Zhang Jian Wu Lei Deng Yu Huang Jian-Feng Yang Ji-Jun Cui Jin Chang Chi Wang Ji Wu Zeng-Shan Yin Wen Chen Cheng Fang Yi-Hua Yan Jun Lin Wei-Ming Xiong Bin Chen Hai-Chao Bao Cai-Xia Cao Yan-Ping Bai Tao Wang Bing-Long Chen Xin-Yu Li Ye Zhang Li Feng Jiang-Tao Su Ying Li Wei Chen You-Ping Li Ying-Na Su Hai-Yan Wu Mei Gu Lei Huang Xue-Jun Tang | 2019 | Research in Astronomy and Astrophysics2019，19，11： | 17 |

| 5 | Efficacy and safety of endoscopic submucosal tunnel dissection for superficial esophageal squamous cell carcinoma and precancerous lesions显示文摘AIM To evaluate the clinical outcomes of patients who underwent endoscopic submucosal tunnel dissection(ESTD) for esophageal squamous cell carcinoma(ESCC) and precancerous lesions.METHODS ESTD was performed in 289 patients. The clinical outcomes of the patients and pathological features of the lesions were retrospectively reviewed.RESULTS A total of 311 lesions were included in the analysis. The en bloc rate, complete resection rate, and curative resection rate were 99.04%, 81.28%, and 78.46%, respectively. The ESTD procedure time was 102.4 ± 35.1 min, the mean hospitalization time was 10.3 ± 2.8 d, and the average expenditure was 3766.5 ± 846.5 dollars. The intraoperative bleeding rate was 6.43%, the postoperative bleeding rate was 1.61%, the perforation rate was 1.93%, and the postoperative infection rate was 9.65%. Esophageal stricture and positive margin were severe adverse events, with an incidence rate of 14.79% and 15.76%, respectively. No tumor recurrence occurred during the follow-up period. CONCLUSION ESTD for ESCC and precancerous lesions is feasible and relatively safe, but for large mucosal lesions, the rate of esophageal stricture and positive margin is high. | Jin Wang Xiao-Nan Zhu Lin-Lin Zhu Wei Chen Yi-Han Ma Tao Gan Jin-Lin Yang | 2018 | World Journal of Gastroenterology2018，24，26： | 15 |
| 6 | Genotypic Characterization of Methicillin-resistant Staphylococcus aureus Isolated from Pigs and Retail Foods in China显示文摘Objective To investigate the genotypic diversity of Methicillin-resistant Staphylococcus aureus(MRSA) isolated from pigs and retail foods from different geographical areas in China and further to study the routes and rates of transmission of this pathogen from animals to food. Methods Seventy-one MRSA isolates were obtained from pigs and retail foods and then characterized by multi-locus sequencing typing(MLST), spa typing, multiple-locus variable number of tandem repeat analysis(MLVA), pulsed-field gel electrophoresis(PFGE), and antimicrobial susceptibility testing. Results All isolated MRSA exhibited multi-drug resistance(MDR). Greater diversity was found in food-associated MRSA(7 STs, 8 spa types, and 10 MLVA patterns) compared to pig-associated MRSA(3 STs, 1 spa type, and 6 MLVA patterns). PFGE patterns were more diverse for pig-associated MRSA than those of food-associated isolates(40 vs. 11 pulse types). Among the pig-associated isolates, CC9-ST9-t899-MC2236 was the most prevalent clone(96.4%), and CC9-ST9-t437-MC621(20.0%) was the predominant clone among the food-associated isolates. The CC9-ST9 isolates showed significantly higher antimicrobial resistance than other clones. Interestingly, CC398-ST398-t034 clone was identified from both pig-and food-associated isolates. Of note, some community-and hospital-associated MRSA strains(t030, t172, t1244, and t4549) were also identified as food-associated isolates. Conclusion CC9-ST9-t899-MC2236-MDR was the most predominant clone in pigs, but significant genetic diversity was observed in food-associated MRSA. Our results demonstrate the great need for improved surveillance of MRSA in livestock and food and effective prevention strategies to limit MDR-MRSA infections in China. | WANG Wei LIU Feng ZULQARNAIN Baloch ZHANG Cun Shan MA Ke PENG Zi Xin YAN Shao Fei HU Yu Jie GAN Xin DONG Yin Ping BAI Yao LI Feng Qin YAN Xiao Mei MA Ai Guo XU Jin | 2017 | Biomedical and Environmental Sciences2017，30，8： | 13 |
| 7 | Seasonal dynamics of water bloom-forming Microcystis morphospecies and the associated extracellular microcystin concentrations in large,shallow,eutrophic Dianchi Lake显示文摘The increasing occurrence of Microcystis blooms is of great concern to public health and ecosystem due to the potential hepatotoxic microcystins(MCs)produced by these colonial cyanobacteria.In order to interpret the relationships between variations of Microcystis morphospecies and extracellular MC concentrations,the seasonal dynamics of phytoplankton community composition,MC concentrations,and environmental parameters were monitored monthly from August,2009 to July,2010.The results indicated that Microcystis dominated total phytoplankton abundance from May to December(96%–99%of total biovolume),with toxic Microcystis viridis and non-toxic Microcystis wesenbergii dominating after July(constituting 65%–95%of the Microcystis population),followed by M.viridis as the sole dominant species from November to January(49%–93%).Correlation analysis revealed that water temperature and nutrient were the most important variables accounting for the occurrence of M.wesenbergii,while the dominance of M.viridis was related with nitrite and nitrate.The relatively low content of MCs was explained by the association with a large proportion of M.viridis and M.wesenbergii,small colony size of Microcystis populations,and low water temperature,pH and dissolved oxygen.The extracellular MC(mean of 0.5±0.2μg/L)of water samples analyzed by enzyme-linked immunosorbent assay(ELISA)demonstrated the low concentrations of MC in Dianchi Lake which implied the low potential risk for human health in the basin.The survey provides the first whole lake study of the occurrence and seasonal variability of Microcystis population and extracellular MCs that are of particular interest for water quality monitoring and management. | Yanlong Wu Lin Li Nanqin Gan Lingling Zheng Haiyan Ma Kun Shan Jin Liu Bangding Xiao Lirong Song | 2014 | Journal of Environmental Sciences2014，26，9： | 12 |

| 9 | Movement of Ordos block and alternation of activity along its boundaries显示文摘The GPS data in and around the Ordos block area indicate that the left-lateral slip rate along the northern or southern margin of the Ordos block is about twice or three times as fast as the right-lateral slip rate along the eastern or western margin of the block. However, many researchers stressed the dextral-slip of the eastern or western boundaries of the Ordos block, and suggested that the block as a whole rotated counterclockwise based on the available geological data. Focusing on the inconsistency, we reexamine the late Cenozoic deformation pattern in the Ordos region based on seismicity data and geodesy data (GPS and leveling) around it. The results indicate that the rigid block-like motion appears to be the basic characteristic of the kinematics of the Ordos region, and this motion is absorbed by the displacement of the faults around the block. When the faults along the northern and southern boundaries of the Ordos block are active, its eastern boundary is inactive. However, if the faults along the eastern boundary are active, the northern and southern are inactive. In recent years, the northern and southern boundaries of the Ordos block are in active. But in the long term, the Ordos block is moving southeastward relative to the Alxa and Yinshan blocks because of the strong pushing of the Tibetan Plateau on its southwestern side, and this deformation is accommodated by the counterclockwise rotation of the block itself. | FAN Junxi (范俊喜) MA Jin (马 瑾) GAN Weijun (甘卫军) | 2003 | Science China Earth Sciences2003，46，z2： | 11 |

| 12 | Recently duplicated sesterterpene(C25) gene clusters in Arabidopsis thaliana modulate root microbiota显示文摘Land plants co-speciate with a diversity of continually expanding plant specialized metabolites(PSMs) and root microbial communities(microbiota).Homeostatic interactions between plants and root microbiota are essential for plant survival in natural environments.A growing appreciation of microbiota for plant health is fuelling rapid advances in genetic mechanisms of controlling microbiota by host plants.PSMs have long been proposed to mediate plant and single microbe interactions.However,the effects of PSMs,especially those evolutionarily new PSMs,on root microbiota at community level remain to be elucidated.Here,we discovered sesterterpenes in Arabidopsis thaliana,produced by recently duplicated prenyltransferase-terpene synthase(PT-TPS) gene clusters,with neo-functionalization.A single-residue substitution played a critical role in the acquisition of sesterterpene synthase(sesterTPS) activity in Brassicaceae plants.Moreover,we found that the absence of two root-specific sesterterpenoids,with similar chemical structure,significantly affected root microbiota assembly in similar patterns.Our results not only demonstrate the sensitivity of plant microbiota to PSMs but also establish a complete framework of host plants to control root microbiota composition through evolutionarily dynamic PSMs. | Qingwen Chen Ting Jiang Yong-Xin Liu Haili Liu Tao Zhao Zhixi Liu Xiangchao Gan Asis Hallab Xuemei Wang Juan He Yihua Ma Fengxia Zhang Tao Jin M.

| 13 | Ground pressure and overlying strata structure for a repeated mining face of residual coal after room and pillar mining显示文摘To investigate the abnormal ground pressures and roof control problem in fully mechanized repeated mining of residual coal after room and pillar mining,the roof fracture structural model and mechanical model were developed using numerical simulation and theoretical analysis.The roof fracture characteristics of a repeated mining face were revealed and the ground pressure law and roof supporting conditions of the repeated mining face were obtained.The results indicate that when the repeated mining face passes the residual pillars,the sudden instability causes fracturing in the main roof above the old goaf and forms an extra-large rock block above the mining face.A relatively stable ‘‘Voussoir beam' structure is formed after the advance fracturing of the main roof.When the repeated mining face passes the old goaf,as the large rock block revolves and touches gangue,the rock block will break secondarily under overburden rock loads.An example calculation was performed involving an integrated mine in Shanxi province,results showed that minimum working resistance values of support determined to be reasonable were respectively 11,412 kN and 10,743 kN when repeated mining face passed through residual pillar and goaf.On-site ground pressure monitoring results indicated that the mechanical model and support resistance calculation were reasonable. | Jiang Bangyou Wang Lianguo Lu Yinlong Sun Xiaokang Jin Gan | 2016 | International Journal of Mining Science and Technology2016，26，4： | 10 |

| 17 | How does the motor relearning program improve neurological function of brain ischemia monkeys?显示文摘The motor relearning program can significantly improve various functional disturbance induced by ischemic cerebrovascular diseases. However, its mechanism of action remains poorly understood. In injured brain tissues, glial fibrillary acidic protein and neurofilament protein changes can reflect the condition of injured neurons and astrocytes, while vascular endothelial growth factor and basic fibroblast growth factor changes can indicate angiogenesis. In the present study, we induced ischemic brain injury in the rhesus macaque by electrocoagulation of the M1 segment of the right middle cerebral artery. The motor relearning program was conducted for 60 days from the third day after model establishment. Immunohistochemistry and single-photon emission CT showed that the numbers of glial fibrillary acidic protein-, neurofilament protein-, vascular endothelial growth factor- and basic fibroblast growth factor-positive cells were significantly increased in the infarcted side compared with the contralateral hemisphere following the motor relearning program. Moreover, cerebral blood flow in the infarcted side was significantly improved. The clinical rating scale for stroke was used to assess neurological function changes in the rhesus macaque following the motor relearning program. Results showed that motor function was improved, and problems with consciousness, self-care ability and balance function were significantly ameliorated. These findings indicate that the motor relearning program significantly promoted neuronal regeneration, repair and angiogenesis in the surroundings of the infarcted hemisphere, and improve neurological function in the rhesus macaque following brain ischemia. | Yong Yin Zhen Gu Lei Pan Lu Gan Dongdong Qin Bo Yang Jin Guo Xintian Hu Tinghua Wang Zhongtang Feng | 2013 | Neural Regeneration Research2013，8，16： | 9 |
| 18 | Measurement of boiling heat transfer coefficient in liquid nitrogen bath by inverse heat conduction method显示文摘Inverse heat conduction method (IHCM) is one of the most effective approaches to obtaining the boiling heat transfer coefficient from measured results. This paper focuses on its application in cryogenic boiling heat transfer. Experiments were conducted on the heat transfer of a stainless steel block in a liquid nitrogen bath, with the assumption of a 1D conduction condition to realize fast acquisition of the temperature of the test points inside the block. With the inverse-heat conduction theory and the explicit finite difference model, a solving program was developed to calculate the heat flux and the boiling heat transfer coefficient of a stainless steel block in liquid nitrogen bath based on the temperature acquisition data. Considering the oscillating data and some unsmooth transition points in the inverse-heat-conduction calculation result of the heat-transfer coefficient, a two-step data-fitting procedure was proposed to obtain the expression for the boiling heat transfer coefficients. The coefficient was then verified for accuracy by a comparison between the simulation results using this expression and the verifying experimental results of a stainless steel block. The maximum error with a revised segment fitting is around 6%, which verifies the feasibility of using IHCM to measure the boiling heat transfer coefficient in liquid nitrogen bath. | Tao JIN Jian-ping HONG Hao ZHENG Ke TANG Zhi-hua GAN | 2009 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2009，10，5： | 8 |
| 19 | Effect of a transverse plasma jet on a shock wave induced by a ramp显示文摘We conducted experiments in a wind tunnel with Mach number 2 to explore the evolution of a transverse plasma jet and its modification effect on a shock wave induced by a ramp with an angle of 24°. The transverse plasma jet was created by arc discharge in a small cylindrical cavity with a 2 mm diameter orifice. Three group tests with different actuator arrangements in the spanwise or streamwise direction upstream from the ramp were respectively studied to compare their disturbances to the shock wave. As shown by a time-resolved schlieren system, an unsteady motion of the shock wave by actuation was found: the shock wave was significantly modified by the plasma jet with an upstream motion and a reduced angle. Compared to spanwise actuation, a more intensive impact was obtained with two or three streamwise actuators working together. From shock wave structures, the control effect of the plasma jet on the shock motion based on a thermal effect, a potential cause of shock modification, was discussed. Furthermore, we performed a numerical simulation by using the Improved Delayed Detached Eddy Simulation(IDDES) method to simulate the evolution of the transverse plasma jet plume produced by two streamwise actuators. The results show that flow structures are similar to those identified in schlieren images. Two streamwise vortices were recognized, which indicates that the higher jet plume is the result of the overlap of two streamwise jets. | Hongyu WANG Jun LI Di JIN Hui DAI Tian GAN Yun WU | 2017 | Chinese Journal of Aeronautics2017，30，6： | 7 |
