12018 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 2018Science Bulletin2018,63,23:54

3A Domestication-Associated Gene GmPRR3b Regulates the Circadian Clock and Flowering Time in Soybean显示文摘Improved soybean cultivars have been adapted to grow at a wide range of latitudes,enabling expansion of cultivation worldwide.However,the genetic basis of this broad adaptation is still not clear.Here,we report the identification of GmPRR3b as a major flowering time regulatory gene that has been selected during domestication and genetic improvement for geographic expansion.Through a genome-wide association study of a diverse soybean landrace panel consisting of 279 accessions,we identified 16 candidate quantitative loci associated with flowering time and maturity time.The strongest signal resides in the known flowering gene E2,verifying the effectiveness of our approach.We detected strong signals associated with both flowering and maturity time in a genomic region containing GmPRR3b.Haplotype analysis revealed that GmPRR3bH6 is the major form of GmPRR3b that has been utilized during recent breeding of modern cultivars.mRNA profiling analysis showed that GmPRR3bH6 displays rhythmic and photoperiod-dependent expression and is preferentially induced under long-day conditions.Overexpression of GmPRR3bH6 increased main stem node number and yield,while knockout of GmPRR3bH6 using CRISPR/Cas9 technology delayed growth and the floral transition.GmPRR3bH6 appears to act as a transcriptional repressor of multiple predicted circadian clock genes,including GmCCAIa,which directly upregulates J/GmELF3a to modulate flowering time.The causal SNP(Chr12:5520945)likely endows GmPRR3bH6 a moderate but appropriate level of activity,leading to early flowering and vigorous growth traits preferentially selected during broad adaptation of landraces and improvement of cultivars.Cong Li Ying-hui Li Yanfei Li Hongfeng Lu Huilong Hong Yu Tian Hongyu Li Tao Zhao Xiaowei Zhou Jun Liu Xinan Zhou Scott A.Jackson Bin Liu Li-juan Qiu 2020Molecular Plant2020,13,5:11
4Geochemical Characteristics of Selenium and Its Correlation to Other Elements and Minerals in Selenium-Enriched Rocks in Ziyang County,Shaanxi Province,China显示文摘Ziyang County, Shaanxi Province, China is a world known selenium(Se)-enriched area, and a severe selenosis incident was reported in Naore Village during the 1990 s. This study investigated the geochemical characteristics of Se and its fractions in Se-enriched rocks from Ziyang. Se distribution is uneven, ranging from 0.23 to 57.00 μg/g(17.29±15.52 μg/g). Se content is higher in slate than chert, and even lower in carbonate rocks. Cd, As and V are enriched but Pb is depleted in Se-enriched strata. Se has different correlations both with TS(total sulfur)(R^2=0.59 for chert) and TC(total carbon)(R^2=0.77 for slate, R^2=0.87 for carbonate). Se has significant positive correlations with V(r=0.65), As(r=0.485), Cd(r=0.459) and Pb(r=0.405). The Se level correlates with mineral content, positively with pyrite, chlorite and illite, negatively with albite. Se associated with sulfide/selenide and elemental Se are the predominant fractions of total recovered Se, suggesting that a reducing environment and the formation of sulfides were significant to Se deposition during its geochemical cycle. Although low concentration of bio-available Se(average 5.62%±3.69%) may reduce the risk of Se poisoning in the target area, utilization of Se-rich rock as natural fertilizer should be restricted.Huan Tian Zhenzhen Ma Xiaolei Chen Hongyu Zhang Zhengyu Bao Changhua Wei Shuyun Xie Shitou Wu 2016Journal of Earth Science2016,27,5:7
5Effect 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 2017Chinese Journal of Aeronautics2017,30,6:7
6数据分析中的对数转换和意义(英文)显示文摘对数转换的方法在生物医学和社会心理研究中处理非正态数据时被广泛应用。本文重点介绍该传统方法在处理非正态数据时存在的严重问题。尽管通常认为对数转换可以减少数据的变异性,使数据更符合正态分布,但是通常并非如此。此外,对数转换后的数据得出的标准统计测试结果往往和未转化的原始数据不相关。我们通过使用模拟数据示例来说明这些问题。我们认为如果采用数据转换,必须非常谨慎应用。我们建议研究者在大多数情况下摒弃这些处理非正态数据的传统方法,选择采用较新的不依赖于数据分布的方法:如广义估计方程(GEE)。Changyong FENG Hongyue WANG Naiji LU Tian CHEN Hua HE Ying LU Xin M.TU 2014上海精神医学2014,26,2:7
7Effects of carbon diffusing field in alloy solvent on the growth of tower-shape diamond single crystal显示文摘High-quality type-Ib tower-shape diamond single crystals were synthesized in cubic anvil high pressure apparatus (SPD-6×1200) at 5.4 GPa and 1250-1450°C. The (100) face of seed crystal was used as the growth face, and FeNiMnCo alloy was used as the solvent/catalyst. Two kinds of carbon diffusing fields (type-B and type-G) were simulated by finite element method (FEM). Using the two kinds of carbon diffusing fields, many diamond single crystals were synthesized. The effects of carbon diffusing fields on the crystal quality and β value (the ratio of height to diameter of diamond crystal) were studied. The results show that using type-B diffusing field, considerable inclusions appeared in tower-shape diamond crystals with high β values; however, using type- G diffusing field, inclusions were reduced markedly in high β values tower-shape diamond crystals, and the crystal, up to 0.6 carat in weight and 5.3 mm in size, was synthesized. Experimental phenomena were explained well with the help of the FEM.XIAO HongYu MA HongAn TIAN Yu LI Rui LI ShangSheng MA LiQiu LI Yong JIA XiaoPeng 2010Chinese Science Bulletin2010,55,1:5
8Dependence of nitrogen concentration in type Ib diamonds on synthesis temperature显示文摘Type Ib diamonds were grown by the temperature gradient method (TGM) at 5.5 GPa and 1500-1560 K in a china-type cubic anvil high pressure apparatus using Ni70Mn25Co5 alloy as solvent/catalyst. The concentration of nitrogen (CN) in type Ib diamonds synthesized at different synthesis temperatures was measured by a Fourier transform infrared (FTIR) spectrometer. The dependence of CN in diamond on synthesis temperature was studied. For the type Ib diamonds synthesized using Ni70Mn25Co5 as catalyst, its CN decreases along with the increase of synthesis temperature.TIAN Yu JIA XiaoPeng ZANG ChuanYi LI ShangSheng XIAO HongYu ZHANG YaFei HUANG GuoFeng LI Rui HAN QiGang MA LiQiu LI Yong CHEN XiaoZhou ZHANG Chong MA HongAn 2009Chinese Science Bulletin2009,54,9:5

10Antimonene:a long-term stable two-dimensional saturable absorption material under ambient conditions for the mid-infrared spectral region显示文摘We experimentally demonstrate a long-term stable two-dimensional saturable absorption material under ambient conditions—multi-layer antimonene feasible for the mid-infrared spectral region—for the first time to our knowledge. The multi-layer antimonene material prepared using a liquid-phase exfoliation method was coated on a quartz/Ca F_2 for characterizations and an Au mirror as a reflection-type saturable absorber(SA) device. It has a modulation depth of 10.5%, a saturation peak intensity of 0.26 GW∕cm^2, and a non-saturation loss of 19.1% measured at 2868.0 nm using the typical power-dependent method. By introducing the SA device into a linear-cavity Ho^(3+)∕ Pr^(3+)-codoped fluoride fiber laser at 2865.0 nm, stable Q-switched pulses were obtained. It generated a maximum output power of 112.3 m W and pulse energy of 0.72 μJ, while the shortest pulse duration and largest repetition rate were 1.74 μs and 156.2 k Hz, respectively. The long-term stability of the SA device was also checked using the same laser setup within 28 days. The results indicate that multi-layer antimonene is a type of promising long-term stable SA material under ambient conditions that can be applied in the mid-infrared spectral region.HONGYU Luo XIANGLING TIAN YING GAO RONGFEI WEI JIANFENG LI JIANRONG QIU YONG LlU 2018Photonics Research2018,6,9:5
11Hexagonal boron nitride nanosheet for effective ambient N2 fixation to NH3显示文摘Industrial production of NH3 from N2 and H2 significantly relies on Haber-Bosch process,which suffers from high energy consume and CO2 emission.As a sustainable and environmentally-benign alternative process,electrochemical artificial N2 fixation at ambient conditions,however,is highly required efficient electrocatalysts.In this study,we demonstrate that hexagonal boron nitride nanosheet (h-BNNS) is able to electrochemically catalyze N2 to NH3.In acidic solution,h-BNNS catalyst attains a high NH3 formation rate of 22.4 μg·h-1·mg-1cat.and a high Faradic efficiency of 4.7% at-0.75 V vs.reversible hydrogen electrode,with excellent stability and durability.Density functional theory calculations reveal that unsaturated boron at the edge site can activate inert N2 molecule and significantly reduce the energy barrier for NH3 fonmation.Ya Zhang Huitong Du Yongjun Ma Lei Ji Haoran Guo Ziqi Tian Hongyu Chen Hong Huang Guanwei Cui Abdullah M.

13Exploring BH_2CN-based hydrophobic hypergolic fuels and effective fuel“additives”: Imidazolylidene cyanoborane complexes显示文摘Two hydrophobic imidazolylidene-cyanoborane complexes were prepared by the introduction of{BH2 CN} into the molecular formula via treatment of imidazolium iodide and Na BH3 CN avoiding literature's tedious and hazardous procedures. These two complexes were fully characterized using IR spectroscopy,~1 H NMR and^(13)C NMR spectroscopy and high-resolution mass spectrometer. The X-Ray structure of NHC-1 has been determined. NHC-2 was proved to be hypergolic with WFNA and displayed the attractive properties such as water immiscibility, wide liquid range(Tg= -22C), short ignition delay time(13 ms), high density(0.98 g/cm3), good density impulse(r Isp, 347 s g cm^(-3)), showing the promising application potential as a fuel and an efficient fuel additive.Xingye Li Jiayu Nan Tian Lu Hongyu Huo Yanqiang Zhang Haibo Li Fude Nie Hongquan Yin Fu-Xue Chen 2018Chinese Chemical Letters2018,29,6:3
14High-temperature superconductivity in sulfur hydride evidenced by alternating-current magnetic susceptibility显示文摘The search for high-temperature superconductivity is one of the research frontiers in physics. In the sulfur hydride system, an extremely high T_c(~200 K) has been recently developed at pressure. However, the Meissner effect measurement above megabar pressures is still a great challenge. Here, we report the superconductivity identification of sulfur hydride at pressure, employing an in situ alternating-current magnetic susceptibility technique. We determine the superconducting phase diagram, finding that superconductivity suddenly appears at 117 GPa and Tcreaches 183 K at 149 GPa before decreasing monotonically with increasing pressure. By means of theoretical calculations, we elucidate the variation of T_c in the low-pressure region in terms of the changing stoichiometry of sulfur hydride and the further decrease in Tcowing to a drop in the electron–phonon interaction parameter λ. This work provides a new insight into clarifying superconducting phenomena and anchoring the superconducting phase diagram in the hydrides.Xiaoli Huang Xin Wang Defang Duan Bertil Sundqvist Xin Li Yanping Huang Hongyu Yu Fangfei Li Qiang Zhou Bingbing Liu Tian Cui 2019National Science Review2019,6,4:2

16Integration of preparation of K,Na-embedded activated carbon and reduction of Zn-bearing dusts显示文摘Large amounts of solid wastes and flue gases are generated in iron and steel production process,probably leading to serious environmental pollution without duly handle.An innovative and green process of simultaneous reduction of zinc-bearing dusts and activation of low-rank coal was developed and its mechanism was clarified in this paper.Under the optimal conditions,the reduced zinc-bearing dusts containing low harmful elements(0.02%Zn,0.015%K and 0.03%Na)could be made as high-quality burden for blast furnace while the low-rank coal was transferred into K,Na-embedded activated carbon,which can be used as effective adsorbent for purification of SO_(2) and NO-containing flue gases.The solid wastes were successfully utilized to treat the flue gases through the process.The synergetic activation and reduction mechanism in the process was revealed.The coupling effect between reduction reactions of metal oxides in the dusts and activation reaction of carbon in the coal promoted the simultaneous reduction and activation process.In the meanwhile,part of the potassium and sodium from the zinc-bearing dusts could be adsorbed by the activated carbon and played a catalytic role in the activation process.Dingzheng Wang Deqing Zhu Jian Pan Zhengqi Guo Congcong Yang Hongyu Tian Yuxiao Xue 2022International Journal of Mining Science and Technology2022,32,3:1

20Genome-wide signatures of the geographic expansion and breeding of soybean显示文摘Soybean is a leguminous crop that provides oil and protein. Exploring the genomic signatures of soybean evolution is crucial for breeding varieties with improved adaptability to environmental extremes. We analyzed the genome sequences of 2,214 soybeans and proposed a soybean evolutionary route, i.e., the expansion of annual wild soybean(Glycine soja Sieb. & Zucc.) from southern China and its domestication in central China, followed by the expansion and local breeding selection of its landraces(G. max(L.) Merr.). We observed that the genetic introgression in soybean landraces was mostly derived from sympatric rather than allopatric wild populations during the geographic expansion. Soybean expansion and breeding were accompanied by the positive selection of flowering time genes, including GmSPA3c. Our study sheds light on the evolutionary history of soybean and provides valuable genetic resources for its future breeding.Ying-Hui Li Chao Qin Li Wang Chengzhi Jiao Huilong Hong Yu Tian Yanfei Li Guangnan Xing Jun Wang Yongzhe Gu Xingpeng Gao Delin Li Hongyu Li Zhangxiong Liu Xin Jing Beibei Feng Tao Zhao Rongxia Guan Yong Guo Jun Liu Zhe Yan Lijuan Zhang Tianli Ge Xiangkong Li Xiaobo Wang Hongmei Qiu Wanhai Zhang Xiaoyan Luan Yingpeng Han Dezhi Han Ruzhen Chang Yalong Guo Jochen C.Reif Scott A.Jackson Bin Liu Shilin Tian Li-juan Qiu 2023Science China(Life Sciences)2023,66,2:1
