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

3Tree ring based streamflow reconstruction for the Upper Yellow River over the past 1234 years显示文摘We established a Juniperus przewalski tree ring width chronology, based on tree ring cores collected from the A’nyêmaqên Mountains. Statistical analysis showed that the chronology was highly correlated with instrumental streamflow records from previous August to current July from the Tangnaihai Station in the upper reaches of the Yellow River, with a correlation coefficient of 0.656. Streamflow for the upper reaches of the Yellow River was reconstructed for the past 1234 years. Low flow periods for the 11-year averaged streamflow reconstruction were definite as lower than mean plus 1 standard deviation, and high flow periods were higher than mean minus 1 standard deviation. Over the past 1234 years, high flows occurred 18 times, and low flows occurred 12 times. The main low flow periods were identified as AD 1140–1156, AD 1295–1309, AD 1473–1500, and AD 1820–1847, and the main high flow periods were identified as AD 846–873, and AD 1375–1400. Extremely low streamflow over the reconstruction period was seen during the late 15th century, coinciding with a widespread drought phenomenon, which took place in the northeastern Tibetan Plateau over the same period. Reconstructed streamflow shows significant low-frequency variability, which is in line with drought variability of neighboring regions, as inferred from tree rings and other proxies. Multi-taper spectral analysis suggests the existence of significant periods of 2–5, 22, 35–38, 55–62, and 114–227 years, particularly significant for cyclic variations of years 159 and 36.GOU XiaoHua DENG Yang CHEN FaHu YANG MeiXue FANG KeYan GAO LinLin YANG Tao ZHANG Fen 2010Chinese Science Bulletin2010,55,36:37

5Methodology development and application of X-ray imaging beamline at SSRF显示文摘This paper introduces some latest developments regarding the X-ray imaging methodology and applications of the X-ray imaging and biomedical application beamline(BL13W1)at Shanghai Synchrotron Radiation Facility in the past 5 years.The photon energy range of the beamline is 8–72.5 keV.Several sets of X-ray imaging detectors with different pixel sizes(0.19–24 lm)are used to realize X-ray microcomputed tomography(X-ray micro-CT)and X-ray in-line phase-contrast imaging.To satisfy the requirements of user experiments,new X-ray imaging methods and image processing techniques are developed.In vivo dynamic micro-CT experiments with living insects are performed in 0.5 s(sampling rate of 2 Hz,2 tomograms/s)with a monochromatic beam from a wiggler source and in 40 ms(sampling rate of 25 Hz,25 tomograms/s)with a white beam from a bending magnet source.A new X-ray imaging method known as move contrast X-ray imaging is proposed,with which blood flow and moving tissues in raw images can be distinguished according to their moving frequencies in the time domain.Furthermore,X-ray speckle-tracking imaging with twice exposures to eliminate the edge enhancement effect is developed.A high-precision quantification method is realized to measure complex three-dimensional blood vessels obtained via X-ray micro-CT.X-ray imaging methods such as three-dimensional X-ray diffraction microscopy,small-angle X-ray scattering CT,and X-ray fluorescence CT are developed,in which the X-ray micro-CT imaging method is combined with other contrast mechanisms such as diffraction,scattering,and fluorescence contrasts respectively.Moreover,an X-ray nano-CT experiment is performed with a 100 nm spatial resolution.Typical user experimental results from the fields of material science,biomedicine,paleontology,physics,chemistry,and environmental science obtained on the beamline are provided.Hong-Lan Xie Biao Deng Guo-Hao Du Ya-Nan Fu Han Guo Yan-Ling Xue Guan-Yun Peng Fen Tao Ling Zhang Ti-Qiao Xiao 2020Nuclear Science and Techniques2020,31,10:7
6Vegfa signaling regulates diverse artery/vein formation in vertebrate vasculatures显示文摘Vascular endothelial growth factor A(Vegfa) signaling regulates vascular development during embryogenesis and organ formation.However,the signaling mechanisms that govern the formation of various arteries/veins in various tissues are incompletely understood.In this study,we utilized transcription activator-like effector nuclease(TALEN) to generate zebrafish vegfaa mutants.vegfaa^(-/-) embryos are embryonic lethal,and display a complete loss of the dorsal aorta(DA) and expansion of the cardinal vein.Activation of Vegfa signaling expands the arterial cell population at the expense of venous cells during vasculogenesis of the axial vessels in the trunk.Vegfa signaling regulates endothelial cell(EC) proliferation after arterial-venous specification.Vegfa deficiency and overexpression inhibit the formation of tip cell filopodia and interfere with the pathfinding of intersegmental vessels(ISVs).In the head vasculature,vegfaa^(-/-) causes loss of a pair of mesencephalic veins(MsVs) and central arteries(CtAs),both of which usually dvelop via sprouting angiogenesis.Our results indicate that Vegfa signaling induces the formation of the DA at the expense of the cardinal vein during the trunk vasculogenesis,and that Vegfa is required for the angiogenic formation of MsVs and CtAs in the brain.These findings suggest that Vegfa signaling governs the formation of diverse arteries/veins by distinct cellular mechanisms in vertebrate vasculatures.Daqing Jin Diqi Zhu Yabo Fang Yiwei Chen Gaihong Yu Weijun Pan Dong Liu Fen Li Tao P.Zhong 2017Journal of Genetics and Genomics2017,44,10:6

13X-ray fluorescence microtomography based on polycapillary- focused X-rays from laboratory source显示文摘X-ray fluorescence microtomography(μXFCT)is a nondestructive analytical technique and has been widely used to nondestructively detect and quantify the elemental composition and distributions in samples. Usually, synchrotron radiation X-rays are used for μXFCT, due to its high flux density. In this paper, a laboratory-sourcebased μXFCT system was developed, in which a polycapillary lens is employed to focus the X-ray beam and improve the flux density. The maximum likelihood expectation maximization algorithm was used to reconstruct the computed tomography slices at a limited number of projections. The experimental results demonstrated that the developed system could reveal the elemental distribution inside the test sample, with an elemental sensitivity of 1000 ppm.Bing-Gang Feng Fen Tao Yi-Ming Yang Tao Hu Fei-Xiang Wang Guo-Hao Du Yan-Ling Xue Ya-Jun Tong Tian-Xi Sun Biao Deng Ti-Qiao Xiao 2018Nuclear Science and Techniques2018,29,6:2
14WRKY33-mediated indolic glucosinolate metabolic pathway confers resistance against Alternaria brassicicola in Arabidopsis and Brassica crops显示文摘The tryptophan(Trp)-derived plant secondary metabolites,including camalexin,4-hydroxyindole-3-carbonylnitrile,and indolic glucosinolate(IGS),show broad-spectrum antifungal activity.However,the distinct regulations of these metabolic pathways among different plant species in response to fungus infection are rarely studied.In this study,our results revealed that WRKY33 directly regulates IGS biosynthesis,notably the production of 4-methoxyindole-3-ylmethyl glucosinolate(4MI3G),conferring resistance to Alternaria brassicicola,an important pathogen which causes black spot in Brassica crops.WRKY33 directly activates the expression of CYP81F2,IGMT1,and IGMT2 to drive sidechain modification of indole-3-ylmethyl glucosinolate(I3G)to 4MI3G,in both Arabidopsis and Chinese kale(Brassica oleracea var.alboglabra Bailey).However,Chinese kale showed a more severe symptom than Arabidopsis when infected by Alternaria brassicicola.Comparative analyses of the origin and evolution of Trp metabolism indicate that the loss of camalexin biosynthesis in Brassica crops during evolution might attenuate the resistance of crops to Alternaria brassicicola.As a result,the IGS metabolic pathway mediated by WRKY33 becomes essential for Chinese kale to deter Alternaria brassicicola.Our results highlight the differential regulation of Trp-derived camalexin and IGS biosynthetic pathways in plant immunity between Arabidopsis and Brassica crops.Han Tao Huiying Miao Lili Chen Mengyu Wang Chuchu Xia Wei Zeng Bo Sun Fen Zhang Shuqun Zhang Chuanyou Li Qiaomei Wang 2022Journal of Integrative Plant Biology2022,64,5:2
15Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population:Findings from the China Cardiometabolic Disease and Cancer Cohort(4C)Study显示文摘Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.ZHU Yuan Yue ZHENG Rui Zhi WANG Gui Xia CHEN Li SHI Li Xin SU Qing XU Min XU Yu CHEN Yu Hong YU Xue Feng YAN Li WANG Tian Ge ZHAO Zhi Yun QIN Gui Jun WAN Qin CHEN Gang GAO Zheng Nan SHEN Fei Xia LUO Zuo Jie QIN Ying Fen HUO Ya Nan LI Qiang YE Zhen ZHANG Yin Fei LIU Chao WANG You Min WU Sheng Li YANG Tao DENG Hua Cong ZHAO Jia Jun CHEN Lu Lu MU Yi Ming TANG Xu Lei HU Ru Ying WANG Wei Qing NING Guang LI Mian LU Jie Li BI Yu Fang 2021Biomedical and Environmental Sciences2021,34,1:2
16CRISPR/Cas9-engineered mutation to identify the roles of phytochromes in regulating photomorphogenesis and flowering time in soybean显示文摘Soybean(Glycine max)responds to ambient light variation by undergoing multiform morphological alterations,influencing its yield potential and stability in the field.Phytochromes(PHYs)are plant-specific red(R)and far-red(FR)light photoreceptors mediating photomorphogenesis and photoperiodic flowering.As an ancient tetraploid,soybean harbors four PHYA,two PHYB,and two PHYE paralogs.Except for GmPHYA2/E4 and GmPHYA3/E3,which have been identified as photoperiod-dependent flowering repressors,the functions of GmPHYs are still largely unclear.We generated a series of individual or combined mutations targeting the GmPHYA or GmPHYB genes using CRISPR/Cas9 technology.Phenotypic analysis revealed that GmPHYB1 mediates predominantly R-light induced photomorphogenesis,whereas GmPHYA2/E4 and GmPHYA3/E3,followed by GmPHYA1 and GmPHYB2,function redundantly and additively in mediating FR light responses in seedling stage.GmPHYA2/E4 and GmPHYA3/E3,with weak influence from GmPHYA1 and GmPHYA4,delay flowering time under natural long-day conditions.This study has demonstrated the diversified functions of GmPHYAs and GmPHYBs in regulating light response,and provides a core set of phytochrome mutant alleles for characterization of their functional mechanisms in regulating agronomic traits of soybean.Fen Zhao Xiangguang Lyu Ronghuan Ji Jun Liu Tao Zhao Hongyu Li Bin Liu Yanxi Pei 2022The Crop Journal2022,10,6:1

20Fouling process and anti-fouling mechanisms of dynamic membrane assisted by photocatalytic oxidation under sub-critical fluxes显示文摘Membrane fouling is often considered as a hindrance for the application of microfiltration/ultrafiltration(MF/UF) for drinking water production. A novel process of photocatalytic membrane reactor/dynamic membrane(PMR/DM), operating in a continuous mode under sub-critical flux, was proposed for the mitigation of membrane fouling caused by humic acids(HAs) in water. The mechanism of membrane fouling alleviation with synergistic photocatalytic oxidation and dynamic layer isolating effect was comprehensively investigated from the characterization of foulant evolution responsible for the reversible and irreversible fouling. The results showed that the PMR/DM utilized photocatalytic oxidation to enhance the porosity and hydrophilicity of the fouling layer by converting the high molecular weight(MW) and hydrophobic HA molecules with carboxylic functional groups and aromatic structures into low-MW hydrophilic or transphilic fractions, including tryptophan-like or fulvic-like substances. The fouling layer formed in the PMR/DM by combination of photocatalytic oxidation and DM running at a sub-critical flux of 100 L·h^-1·m^-2, was more hydrophilic and more porous, resulting in the lowest trans-membrane pressure(TMP) growth rates, as compared to the processes of ceramic membrane(CM), DM and PMR/CM.Meanwhile, the dynamic layer prevented the foulants, particularly the high-MW hydrophobic fractions,from contacting the primary membrane, which enabled the membrane permeability to be restored easily.Tao Yang Fen Liu Houfeng Xiong Qiyong Yang Fushan Chen Changchao Zhan 2019Chinese Journal of Chemical Engineering2019,27,8:1
