| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 2 | The Reference Genome of Tea Plant and Resequencing of 81 Diverse Accessions Provide Insights into Its Genome Evolution and Adaptation显示文摘Tea plant is an important economic crop,which is used to produce the world's oldest and most widely consumed tea beverages.Here,we present a high-quality reference genome assembly of the tea plant(Camellia sinensis var.sinensis)consisting of 15 pseudo-chromosomes.LTR retrotransposons(LTR-RTs)account for 70.38%of the genome,and we present evidence that LTR-RTS play critical roles in genome size expansion and the transcriptional diversification of tea plant genes through preferential insertion in promoter regions and introns.Genes,particularly those coding for terpene biosynthesis pro-teins,associated with tea aroma and stress resistance were significantly amplified through recent tandem duplications and exist as gene clusters in tea plant genome.Phylogenetic analysis of the sequences of 81 tea plant accessions with diverse origins revealed three well-differentiated tea plant populations,support-ing the proposition for the southwest origin of the Chinese cultivated tea plant and its later spread to western Asia through introduction.Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome,particularly those associated with tea quality and stress resis-tance.The genomic sequences of the reported reference and resequenced tea plant accessions provide valuable resources for future functional genomics study and molecular breeding of improved cul-tivars of tea plants. | Enhua Xia Wei Tong Yan Hou Yanlin An Linbo Chen Qiong Wu Yunlong Liu Jie Yu Fangdong Li Ruopei Li Penghui Li Huijuan Zhao Ruoheng Ge Jin Huang Ali Inayat Mallano Yanrui Zhang Shengrui Liu Weiwei Deng Chuankui Song Zhaoliang Zhang Jian Zhao Shu Wei Zhengzhu Zhang Tao Xia Chaoling Wei Xiaochun Wan | 2020 | Molecular Plant2020，13，7： | 51 |

| 5 | Constructal design progress for eight types of heat sinks显示文摘This review paper summarizes constructal design progress performed by the authors for eight types of heat sinks with ten performance indexes being taken as the optimization objectives,respectively,by combining the methods of theoretical analysis and numerical calculation.The eight types of heat sinks are uniform height rectangular fin heat sink,non-uniform height rectangular fin heat sink,inline cylindrical pin-fin heat sink(ICPHS),plate single-row pin fin heat sink(PSRPHS),plate inline pin fin heat sink(PIPHS),plate staggered pin fin heat sink(PSPHS),single-layered microchannel heat sink(SLMCHS)with rectangular cross sections and double-layered microchannel heat sink(DLMCHS)with rectangular cross sections,respectively.And the ten performance indexes are heat transfer rate maximization,maximum thermal resistance minimization,minimization of equivalent thermal resistance which is defined based on the entransy dissipation rate(equivalent thermal resistance for short),field synergy number maximization,entropy generation rate minimization,operation cost minimization,thermo-economic function value minimization,pressure drop minimization,enhanced heat transfer factor maximization and efficiency evaluation criterion number maximization,respectively.The optimal constructs of the eight types of heat sinks with different constraints and based on the different optimization objectives are compared with each other.The results indicated that the optimal constructs mostly are different based on different optimization objectives under the same boundary condition.The optimization objective should be suitable chosen based on the focus when the constructal design for one heat sink is performed.The results obtained herein have some important theoretical significances and application values,and can provide scientific bases and theoretical guidelines for the thermal design of real heat sinks and their applications. | CHEN LinGen YANG AiBo FENG HuiJun GE YanLin XIA ShaoJun | 2020 | Science China(Technological Sciences)2020，63，6： | 25 |
| 6 | Thermodynamics and kinetics of phase transformation in rare earth–magnesium alloys:A critical review显示文摘Magnesium and its alloys are significant superior metallic materials for structural components in automobile and aerospace industries due to their excellent physicomechanical properties.The Mg–rare earth(RE)systems have attracted great interests because RE additions can improve both the deformability and the strength of Mg alloys through solid solution strengthening and precipitation hardening mechanisms.This paper focuses on the interface stability,together with thermodynamics and kinetics of nucleation and growth of the key phases and matrix phases in Mg–RE alloys.In this paper,the theory and recent advances on Mg–RE alloys,especially for the interface stability,thermodynamics and kinetics of nucleation and growth of the key phases and matrix phases,together with their relationships with micro-structures,and macroscopic properties,are reviewed.By combining the thermodynamics/kinetics integrated simulations with various advanced experimental techniques,“reverse”design of Mg–RE alloys starting from the target service performance is put forward as a kind of scientific paradigm with rational design. | Qun Luo Yanlin Guo Bin Liu Yujun Feng Jieyu Zhang Qian Li Kuochih Chou | 2020 | Journal of Materials Science & Technology2020，44，9： | 26 |
| 7 | A distributed scheme developed for eco-hydrological modeling in the upper Heihe River显示文摘Modeling the hydrological processes at catchment scale requires a flexible distributed scheme to represent the catchment topography,river network and vegetation pattern.This study has developed a distributed scheme for eco-hydrological simulation in the upper Heihe River.Based on a 1 km×1 km grid system,the study catchment is divided into 461 sub-catchments,whose main streams form the streamflow pathway.Furthermore,a 1 km grid is represented by a number of topographically similar'hillslope-valley'systems,and the hillslope is the basic unit of the eco-hydrological simulation.This model is tested with a simplified hydrological simulation focusing on soil-water dynamics and streamflow routing.Based on a 12-year simulation from 2001 to 2012,it is found that variability in hydrological behavior is closely associated with climatic and landscape conditions especially vegetation types.The subsurface and groundwater flows dominate the total river runoff.This implies that the soil freezing and thawing process would significantly influence the runoff generation in the upper Heihe basin.Furthermore,the runoff components and water balance characteristics vary among different vegetation types,showing the importance of coupling the vegetation pattern into catchment hydrological simulation.This paper also discusses the model improvement to be done in future study. | YANG DaWen GAO Bing JIAO Yang LEI Hui Min ZHANG YanLin YANG HanBo CONG ZhenTao | 2015 | Science China Earth Sciences2015，58，1： | 20 |
| 8 | Adaptive and regulatory mechanisms in aged rats with postoperative cognitive dysfunction显示文摘Inflammation may play a role in postoperative cognitive dysfunction. 5′ Adenosine monophosphate-activated protein kinase, nuclear factor-kappa B, interleukin-1β, and tumor necrosis factor-α are involved in inflammation. Therefore, these inflammatory mediators may be involved in postoperative cognitive dysfunction. Western immunoblot analysis revealed 5′ adenosine monophosphate-activated protein kinase and nuclear factor-kappa B in the hippocampus of aged rats were increased 1–7 days after splenectomy. Moreover, interleukin-1β and tumor necrosis factor-α were upregulated and gradually decreased. Therefore, these inflammatory mediators may participate in the splenectomy model of postoperative cognitive dysfunction in aged rats. | Yanlin Bi Shuyun Liu Xinjuan Yu Mingshan Wang Yuelan Wang | 2014 | Neural Regeneration Research2014，9，5： | 17 |

| 10 | Earthquake-induced soft-sediment deformation structures in the Mesoproterozoic Wumishan Formation,North China,and their geologic implications显示文摘Soft-sediment structures are key to defining seismites. Two soft-sediment deformation horizons, bounded by undeformed carbonate strata, have been found in the Wumishan Formation in the Jumahe region, 175 km southwest of Beijing. One is in the lowest part of Wumishan Formation; and the other is in the uppermost part of Litho-member I. The soft-sediment structures in these two horizons fall into three categories: mould-and-sag structures, hydraulic shatterings and liquefaction dikes. The mould-and-sag structures are divided into two types: one developed in tidal-flat sediments, accompa-nied by many liquefaction-related structures and characterized by autochthonous post-earthquake sediments in sags, and the other type developed in deep-water environments, is not associated with liquefaction structures, and is overlain immediately by seismogenic tsunamites. The hydraulic shat-terings are composed of pockets of fluidization conglomerate, sand intrusions, and syndepositional faults. The liquefaction dikes fall into two categories: hydraulic-fracturing dikes and lateral-spreading dikes. The former are steep, planar, and pinch out upwards. The latter are snake-like and characterized by no diapir-related drag structures in surrounding rocks. Examination of the attitudes and strati-graphic positions of these structures suggests that these soft-sediment structures are seismogenic, and consequently, are seismites. Most seismites in the Wumishan Formation are developed near the former western, margin fault of Yanliao rift. This occurrence suggests that they could be related to movements on this fault. Other geological implications are discussed. | ZHANG ChuanHeng WU ZhengJie GAO LinZhi WANG Wei TIAN YanLin MA Chao | 2007 | Science China Earth Sciences2007，50，3： | 15 |
| 11 | Reactivation of γ-globin expression through Cas9 or base editor to treat β-hemoglobinopathies显示文摘Dear Editor,Mutations in the β-globin gene,the essential component of adult hemoglobin(HbA;a2p2),results in either a production of aberrant sickle hemoglobin(HbS)leading to sickle cell disease(SCD)or an insufficient β-globin synthesis leading to β-thalassemia.These two major forms of β-hemoglobinopathies cause impaired erythropoiesis and life-threatening anemia.Clinical evidence has suggested that reaaivation of fetal γ-globin(HBG)gene expression which is normally silenced after birth by certain genetic mutations can ameliorate the clinical course of β-hemoglobinopathies. | Liren Wang Linxi Li Yanlin Ma Handan Hu Qi Li Yang Yang Wenbang Liu Shuming Yin Wei Li Bin Fu Ryo Kurita Yukio Nakamura Mingyao Liu Yongrong Lai Dali Li | 2020 | Cell Research2020，30，3： | 14 |

| 16 | The large increase of δ^(13)C_(carb)-depth gradient and the end-Permian mass extinction显示文摘Carbonate carbon isotope δ(13Ccarb) has received considerable attention in the Permian-Triassic transition for its rapid negative shift coinciding with the great end-Permian mass extinction event.The mechanism has long been debated for such a δ13Ccarb negative excursion through the end-Permian crisis and subsequent large perturbations in the entire Early Triassic.A δ13Ccarb depth gradient is observed at the Permian-Triassic boundary sections of different water-depths,i.e.,the Yangou,Meishan,and Shangsi sections,and such a large δ13Ccarb-depth gradient near the end-Permian mass extinction horizon is believed to result from a stratified Paleotethys Ocean with widespread anoxic/euxinic deep water.The evolution of δ13Ccarb-depth gradient combined with paleontological and geochemical data suggests that abundant cyanobacteria and vigorous biological pump in the immediate aftermath of the end-Permian extinction would be the main cause of the large δ13Ccarb-depth gradient,and the enhanced continental weathering with the mass extinction on land provides a mass amount of nutriment for the flourishing cyanobacteria.Photic zone anoxia/euxinia from the onset of chemocline upward excursion might be the direct cause for the mass extinction whereas the instability of chemocline in the stratified Early Triassic ocean would be the reason for the delayed and involuted biotic recovery. | SONG HaiJun TONG JinNan XIONG YanLin SUN DongYing TIAN Li SONG HuYue | 2012 | Science China Earth Sciences2012，55，7： | 11 |
| 17 | Study of the structure of unstable nuclei through the reaction experiments显示文摘Along with the development of the radioactive nuclear beam facility, the study of the structure of unstable nuclei has progressed rapidly over the last few decades. Due to the weakly binding property, the structure information of the unstable nuclei comes primarily from the scattering or reaction experiments. Therefore it would be very important to understand clearly the reaction mechanism involved in the experiment. We outlined here the major reaction mechanisms which are adequate to the study of unstable nuclei, with the focus on the new phenomena and methods in comparison with those with traditional stable nucleus beam. Especially emphasized are the breakup and knockout reactions, developed as accurate tools for spectroscopy investigation into the nuclear structure with low intensity secondary beam. Couplings of the breakup channel to the elastic scattering and the fusion and transfer reactions are also reviewed. | CAO ZhongXin & YE YanLin State Key Laboratory of Nuclear Physics and Technology, School of Physics, Peking University, Beijing 100871, China | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，S1： | 10 |
| 18 | Performance optimization of a class of combined thermoelectric heating devices显示文摘A detailed model of thermally-driven combined thermoelectric(TE) heating device is established. The device consists of twostage TE heat pump(TTEH) and two-stage TE generator(TTEG) with four external heat exchangers(HEXs). Both internal losses and external heat transfer irreversibilities are considered in the model. The heating capacity and the coefficient of performance(COP) of the device are improved through numerical optimization,which is of great significance to the application of the device. The distribution of the total TE element number among four TE devices and the distribution of the total external heat conductance among the four external HEXs are optimized. The results show that both the reservoir temperatures of TTEG and TTEH have significant influences on the performance and the corresponding optimum parameters of the device. The COP can reach 0.14 after optimization when the temperature difference of heat source is 150 K and the temperature difference of heating is 10 K. | CHEN LinGen MENG FanKai GE YanLin FENG HuiJun XIA ShaoJun | 2020 | Science China(Technological Sciences)2020，63，12： | 10 |
| 19 | Electrospun nanofibers as a wound dressing for treating diabetic foot ulcer显示文摘Diabetes is one of the most prevalent diseases in the world with high-mortality and complex complications including diabetic foot ulcer(DFU). It has been reported that the difficulties in repairing the wound related to DFU has much relationship with the wound infection,change of inflammatory responses, lack of extracellular matrix(ECM), and the failure of angiogenesis. Following the development of medical materials and pharmaceutical technology, nanofibers has been developed by electrospinning with huge porosity, excellent humidity absorption, a better oxygen exchange rate, and some antibacterial activities. That is to say, as a potential material, nanofibers must be a wonderful candidate for the DFU treatment with so many benefits. Careful selection of polymers from natural resource and synthetic resource can widen the nanofibrous application. Popular methods applied for the nanofibrous fabrication consist of uniaxial electrospinning and coaxial electrospinning. Furthermore, nanofibers loading chemical, biochemical active pharmaceutical ingredient(API)or even stem cells can be wonderful dosage forms for the treatment of DFU. This review summarizes the present techniques applied in the fabrication of nanofibrous dressing(ND)that utilizes a variety of materials and active agents to offer a better health care for the patients suffering from DFU. | Yan Liu Shiya Zhou Yanlin Gao Yinglei Zhai | 2019 | Asian Journal of Pharmaceutical Sciences2019，14，2： | 10 |
| 20 | Fluid–solid coupling analysis of rock pillar stability for concealed karst cave ahead of a roadway based on catastrophic theory显示文摘In order to study the mechanism of water inrush from a concealed, confined karst cave, we established a fluid–solid coupling model of water inrush from a concealed karst cave ahead of a roadway and a strength reduction method in a rock pillar for preventing water inrush based on catastrophic theory. Fluid–solid coupling effects and safety margins in a rock pillar were studied. Analysis shows that rock pillar instability, exerted by disturbance stress and seepage stress, is the process of rock pillar catastrophic destabilization induced by nonlinear extension of plastic zones in the rock pillar. Seepage flow emerges in the rock pillar for preventing water inrush, accompanied by mechanical instability of the rock pillar. Taking the accident of a confined karst cave water-inrush of Qiyi Mine as an example, by studying the safety factor of the rock pillar and the relationship between karst cave water pressure and thickness of the rock pillar,it is proposed that rock pillar thickness with a safety factor equal to 1.5 is regarded as the calculated safety thickness of the rock pillar, which should be equal to the sum of the blasthole depth, blasting disturbance depth and the calculated safety thickness of the rock pillar. The cause of the karst water inrush at Qiyi Mine is that the rock pillar was so small that it did not possess a safety margin. Combining fluid–solid coupling theory, catastrophic theory and strength reduction method to study the nonlinear mechanical response of complicated rock engineering, new avenues for quantitative analysis of rock engineering stability evaluation should be forthcoming. | Zhao Yanlin Peng Qingyang Wan Wen Wang Weijun Chen Bin | 2014 | International Journal of Mining Science and Technology2014，24，6： | 9 |
