| 1 | High-resolution data collection for analysis of sediment dynamic processes associatedwith combined current-wave action over intertidal flats显示文摘An MIDAS-400 Customised Data Ac- quisition System was deployed to obtain current ve- locity and suspended sediment concentration profiles over the intertidal flat at Wanggang, on the Jiangsu coast (China). At the same time, seawater tempera- ture, conductivity and pressure were measured. Us- ing a data sampling rate of 4 Hz, the high-frequency pressure signals in response to water surface fluc- tuations were recorded and subsequently trans- formed into wave parameters. The analytical results show that the apparent bed roughness length has a magnitude close to the height of sand ripples, which is much larger than the grain size diameter. The bot- tom shear stress associated with current-wave in- teraction is higher than the tidally-induced stress and intensified turbulent mixing and resuspension. Fur- thermore, several suspended sediment concentration peaks occurred during a tidal cycle, which can be related to strong turbulence near the bed caused by frontal tidal currents and the enhanced resuspension; advection and extreme weather conditions (e. g. storms and strong winds) also played an important role. Finally, large net suspended sediment fluxes were observed to present when the flood or ebb currents prolonged, i.e. the flow became quasi-unid- irectional during a tidal cycle. In general, the MIDAS- 400 is a suitable tool for high-resolution data collec- tion for the situations of combined current-wave ac- tion over intertidal flats; the data obtained can be used to analyze the processes and mechanisms of material transport. | WANG Yaping GAO Shu JIA Jianjun | 2006 | Chinese Science Bulletin2006，51，7： | 17 |
| 2 | Impact of the cord-grass Spartina alterniflora on sedimentary and morphological evolution of tidal salt marshes on the Jiangsu coast,China显示文摘The tidal flats of the Wanggang area, on the Jiangsu coast, represent the largest continuously distributed coastal wetland in terms of area coverage in China, and the dynamics of tidal flat accretion and erosion is highly complicated. The cord-grass Spartina alterniflora, which was introduced artificially into the Jiangsu coast, has significant influences on the regional tidal flat evolution in terms of deposition rate, spacial sediment distribution patterns and tidal creek morphology. On the basis of the data set of bed elevation and accumulation rate for different periods of time, the applicability of the Pethick-Allen model to the Jiangsu tidal salt marshes is discussed. In addition, caesium-137 dating was carried out for sediment samples collected from the salt marsh of the Wangang area. In combination with the caesium-137 analysis and the data collected from literature, the Pethick-Allen model was used to derive the accumulation rate in the Wanggang tidal flat for the various periods. The results show that the pattern of tidal flat accretion has been modified, due to more rapid accretion following the introduction of S.alterniflora to the region. Surficial sediment samples were collected from representative profiles and analyzed for grain size with a laser particle analyzer. The result shows that fine-grained sediment has been trapped by the plant, with most of the sediment deposited on the Suaeda salsa and Spartina angelica flats being derived from drainage creeks rather than the from gently sloping tidal flats. Remote sensing analysis and in situ observations indicate that the creeks formed in the S.alterniflora flat have a relatively small ratio of width to depth, a relatively high density, and are more stable than the other tidal flat creek systems in the study area. | WANG Aijun GAO Shu JIA Jianjun | 2006 | Acta Oceanologica Sinica2006，25，4： | 15 |
| 3 | Effect of graphene nanoplatelets(GNPs)addition on strength and ductility of magnesium-titanium alloys显示文摘Effect of graphene nanoplatelets(GNPs)addition on mechanical properties of magnesium–10wt%Titanium(Mg–10Ti)alloy is investigated in current work.The Mg-(10Ti+0.18GNPs)composite was synthesized using the semi powder metallurgy method followed by hot extrusion.Microstructural characterization results revealed the uniform distribution of reinforcement(Ti+GNPs)particles in the matrix,therefore(Ti+GNPs)particles act as an effective reinforcing filler to prevent the deformation.Room temperature tensile results showed that the addition of Ti+GNPs to monolithic Mg lead to increase in 0.2%yield strength(0.2%YS),ultimate tensile strength(UTS),and failure strain.Scanning Electron Microscopy(SEM),Energy-Dispersive X-ray Spectroscopy(EDS)and X-Ray Diffraction(XRD)were used to investigate the surface morphology,elemental dispersion and phase analysis,respectively. | Muhammad Rashad Fusheng Pan Aitao Tang Yun Lu Muhammad Asif Shahid Hussain Jia She Jun Gou Jianjun Mao | 2013 | Journal of Magnesium and Alloys2013，1，3： | 10 |
| 4 | Comprehensive Management of Daily Living Activities,behavioral and Psychological Symptoms,and Cognitive Function in Patients with Alzheimer's Disease:A Chinese Consensus on Alzheimer's Disease显示文摘Alzheimer's disease(AD)is the most common cognitive disorder in the elderly.Its main clinical manifestations are cognitive decline(C),behavioral and psychological symptoms(B),and a decline in the activities of daily living(A),also known as ABC symptoms.Early identification and evaluation of ABC symptoms are helpful for establishing the accurate diagnosis,comprehensive treatment,and prognosis of AD.To guide Chinese clinical practice for optimization of the comprehensive management of AD,in 2018,The Academy of Cognitive Disorder of China gathered 22 neurologists and gerontologists in China to build a consensus on the comprehensive management of AD.Based on a review of the evidence,the consensus summarizes the pathogenesis,pathological changes,clinical manifestations,evaluation,diagnosis,drug and non-drug treatment,and patient care for AD.Focus group discussion was used to establish a flowchart of comprehensive ABC management for AD patients.The new consensus provides a feasible AD management process for clinicians. | Jianjun Jia Jun Xu Jun Liu Yongjun Wang Yanjiang Wang Yunpeng Cao Qihao Guo Qiuming Qu Cuibai Wei Wenshi Wei Junjian Zhang Enyan Yu | 2021 | Neuroscience Bulletin2021，37，7： | 10 |

| 7 | Simulation of electro-slag re-melting process of 120t large ingot for nuclear power station and its application显示文摘Further research on metallic materials for the super critical rotator and the main pipe line of a nuclear power station is very important for developing the nuclear power industry. In this study, the mathematical model for 120 t large ingot was established, and the computer program ESR3D was developed to simulate the whole electro-slag re-melting (ESR) process. This includes the electrode melting, metallic droplet falling, metal pool forming, metal pool and slag pool rising and moving, installation of top crystallizer, ingot solidifying, etc. The simulated average melting rate of the electrode was in good agreement with that in practical production. The optimized parameters were used to produce 80-120 t large ingots, and the quality of the ingots satisfied the specifications of nuclear power and the super critical generating unit. | Liu Xihai Wang Junqing Jia Weiguo Gao Jianjun Zhao Lin Tang Zuobin | 2011 | China Foundry2011，8，4： | 6 |
| 8 | Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery. | Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018，30，5： | 5 |
| 9 | Predictive value of serum levels of transforming growth factor beta 1 for the short-term effects of radiotherapy and chemotherapy in patients with esophageal cancer显示文摘Objective To investigate variation in levels of transforming growth factor beta 1(TGF-β1)before and after radiotherapy in patients with esophageal cancer in order to evaluate the predictive value of TGF-β1 for the effects of radiotherapy Methods A total of 140 patients with esophageal squamous carcinoma undergoing radical radiation therapy in the Department of Oncology from March 2015 to December 2017 were enrolled.The patients were divided into the effective(115 cases)and ineffective(25 cases)groups according to World Health Organization(WHO)criteria for the evaluation of solid tumors(2009 RECIST standard).TGF-β1 levels were measured in all patients by using enzyme-linked immunosorbent assay(ELISA).Multiple-factor analysis of the predictive value of the treatment efficacy was performed by Cox regression analysis.Results After radiotherapy,36,79,and 25 cases experienced complete response(CR),partial response(PR),and no response(NR),respectively,with a total effective rate of 82.14%.The TGF-β1 level was significantly lower in the effective group than that in the ineffective group(P<0.05)and covariance analysis revealed significantly reduced TGF-β1 level in esophageal cancer patients following radiotherapy.The multi-factor Cox regression model revealed that the predictive value of TGF-β1 for the effect of radiotherapy was largest,with a hazard ratio[HR]of 1.955(P=0.002),followed by exposure dose,with(HR=1.367;P=0.035).Conclusion Serum TGF-β1 level can serve as a predictor for the short-term effects of radiotherapy in patients with esophageal cancer. | Fei Gao Lin Jia Jianjun Han Jisheng Wang Yun Wang | 2018 | Oncology and Translational Medicine2018，4，1： | 4 |
| 10 | Theory, technology and prospects of conventional and unconventional natural gas显示文摘The development of natural gas in China has entered a golden and leap-forward stage, which is a necessary bridge to clean energy. This in-depth study on the status quo, theory, technology and prospect of natural gas development shows:(1) The global remaining proven recoverable reserves of natural gas are 186×1012 m3, and the reserves-production ratio is 52.4, indicating a solid resource base for long-term and rapid development.(2) Ten formation and distribution laws of conventional and unconventional natural gas reservoirs have been proposed. In terms of exploration geology, the theory of conventional 'monolithic' giant gas fields with different gas sources, and an unconventional gas accumulation theory with continuous distribution of 'sweet areas' in different lithologic reservoirs have been established; in terms of development geology, a development theory of conventional structural gas reservoirs is oriented to 'controlling water intrusion', while a development theory of unconventional gas is concentrated on man-made gas reservoirs.(3) With the geological resources(excluding hydrates) of 210×1012 m3 and the total proven rate of the resources less than 2% at present, the natural gas in China will see a constant increase in reserve and production; by 2030, the proven geological reserves of natural gas are expected to reach about(6 000-7 000)×108 m3, the production of conventional and unconventional natural gas each will reach about 1 000×108 m3, and the gas consumption will reach 5 500×108 m3. The dependence on imported natural gas may be 64% by 2030, and 70% by 2050.(4) Ten measures for future development of natural gas have been proposed, including strengthening exploration in large-scale resource areas, increasing the development benefits of unconventional gas, and enhancing the peak adjusting capacity of gas storage and scale construction of liquified natural gas. | ZOU Caineng YANG Zhi HE Dongbo WEI Yunsheng LI Jian JIA Ailin CHEN Jianjun ZHAO Qun LI Yilong LI Jun YANG Shen | 2018 | Petroleum Exploration and Development2018，45，4： | 4 |
| 11 | Effects of Shuyusan on monoamine neurotransmitters expression in a rat model of chronic stress-induced depression显示文摘Shuyusan, a traditional Chinese medicine, was shown to improve depression symptoms and behavioral scores, as well as increase 5-hydroxytryptamine (5-HT), 5-hydroxyindoleacetic acid, and 5-hydroxytryptophan levels, in a rat model of chronic stress-induced depression. However, dopamine, noradrenalin, and 3-methoxy-4-hydroxyphenylglycol expressions remained unchanged following Shuyusan treatment. Compared with the model group, the number of 5-HT-positive neurons in layers 4-5 of the frontal cortex, as well as hippocampal CA1 and CA3 regions, significantly increased following Shuyusan treatment. These results suggested that Shuyusan improved symptoms in a rat model of chronic stress-induced depression with mechanisms that involved 5-HT, 5-HT metabolite, 5-HT precursor expressions. | Yuanyuan Zhang Jianjun Jia Liping Chen Zhitao Han Yulan Zhao Honghong Zhang Yazhuo Hu | 2011 | Neural Regeneration Research2011，6，33： | 4 |
| 12 | Interpreting grain-size trends associated with bedload transport on the intertidal fiats at Dafeng,central Jiangsu coast显示文摘A MIDAS-400 customized data acquisi- tion system has been used for the high-resolution sediment dynamic measurements over the Dafeng intertidal flats of northern Jiangsu during 6 tidal cy- cles from July 3 to July 10, 2003. The bed shear stress and bedload transport rates, in response to wave-current interactions, are calculated, which in- dicate that wind waves enhance the bottom shear stress and bedload transport rates. At the station for measurements, bedload transport was directed to seaward, with a sediment discharge of 30—150 kg·m?1 per tidal cycle. The surficial sediment samples were collected from a grid with 10 m spatial intervals over a rectangle 2×104 m2 experimental area, near the MIDAS-400 during the spring tide of July 4, 2003, and the neap tide of July 9, 2003. In addition, leveling survey was undertaken to obtain the detailed topog- raphy of the sampling area. Grain-size trend analysis of the sediment samples shows that the bedload transport patterns are complex, mainly controlled by the hydrodynamics and local geomorphology (e.g. tidal creeks) over the intertidal flats. Furthermore, the grain-size trends pattern during the neap tide rather than during the spring tide is consistent with the cal- culated bedload transport, and the grain-size trend vectors for the spring tide are larger than those forthe neap tide, indicating that the sampling thickness of surficial sediment during the neap tide may contain the information on the geomorphological evolution (or sediment deposition/erosion) from the spring to the neap tide. | JIA Jianjun WANG Yaping GAO Shu WANG Aijun LI Zhanhai | 2006 | Chinese Science Bulletin2006，51，3： | 3 |

| 16 | Assessing the vulnerability of changing coasts,Hainan Island,China显示文摘Knowledge of coastline changes and vulnerability is of great importance to local government departments that are responsible for the management and development of coastal zones.To study the nature of change and vulnerability along the coasts of the Hainan Island,we collected a large number of sediment samples through the last few years,and reconstructed the changes of the coastline by combining the data of sediment grain-size analysis and the nautical charts/TM RS imaginary.Contrary to being almost free from erosion(as expected from the findings that the coastlines are in a relatively stable state),four major cities in Hainan(i.e.,Haikou,Wenchang,Sanya and Changjiang) turned out to be suffered from a moderate coastal vulnerability primarily because of the large populations that impose considerable pressure on the coastlines.Thus,the assessment methodology utilized in this study,including both anthropogenic and natural factors,serves as a useful tool to obtain a comprehensive understanding of coastline vulnerability for local government,in terms of coastal management and adaptation. | WANG Yaping SHI Benwei ZHANG Liang JIA Jianjun XIA Xiaomin ZHOU Liang YU Rui YANG Yang GAO Jianhua | 2017 | Acta Oceanologica Sinica2017，36，4： | 3 |

| 19 | Influence of External Electric Field and Pre-ionization on Characteristics of Discharge Plasma in High-power Xenon Flashlamp显示文摘This work is devoted to experimentally study the characteristics of discharge plasma in high power xenon flashlamps.In the experiments,plasma channel profiles are captured by using a high speed CCD camera,and the radiation energy of the flashlamp is obtained by a pyroelectric energy meter.Voltage and current curves are recorded to shed light on the plasma characteristics.With these diagnostic methods,typical factors influencing the evolution process of plasma channel are studied,including the external electric field and the pre-ionization.The electric potential distribution in the flashlamp influence the plasma channel characteristics the most significantly.The plasma channel pattern for the cases with grounded wires is different from that with ungrounded metal wires.When the wire is ungrounded,it is the coupling voltage between the metal wire and the flashlamp that influences the development of plasma channel.In terms of radiation efficiency,it is proven that there is an optimal interval within 200~300μs between the pre-ionization pulse and the main pulse. | LIU Jianjun LI Haibing HU Lili LI Xingwen YANG Zefeng JIA Shenli e | 2013 | 高电压技术2013，39，9： | 2 |
| 20 | A new electroplated Ir/Ir(OH)_x pH electrode and its application in the coastal areas of Newport Harbor, California显示文摘Resulting from the rising levels of atmospheric carbon, ocean acidification has become a global problem. It has significant impacts on the development, survival, growth and physiology of marine organisms. Therefore, a highprecision sensor is urgently needed to measure the pH of sea-water. Iridium wire with a diameter of 0.25 mm is used as the substrate, and an Ir/Ir(OH)_x pH electrode is prepared by a one-step electrochemical method in a Li OH solution at the room temperature. A scanning electron microscope(SEM) observation reveals that it is coated with nanoscale particles. In laboratory tests, the electrode exhibits a very promising pH response, with an ideal Nernst slope(56.14–59.52), fast response, good stability and long life-span in tested pH buffer solutions. For a sea trial,four pH electrodes and one Ag/Ag Cl reference electrode are integrated with a self-made chemical sensor, and a profile detection of nearly 70 m is implemented near Newport Harbor, California on August 3, 2015. The results reflect that the pH value measured by the sensor is very close to the data given by Sea-Bird 911 plus CTD, with a difference value ranging from 0.000 075 to 0.064 719. And the sensor shows a better data matching degree in 0–40m water depth. In addition, the high precision and accuracy of the sensor make it possible to use in the ocean observation field. | ZHANG Xiao YE Ying KAN Yating HUANG Yuanfeng JIA Jianjun ZHAO Yue CHEN Chen-Tung Arthur QIN Huawei | 2017 | Acta Oceanologica Sinica2017，36，5： | 2 |
