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

5Spatial-temporal Changes of Vegetation Cover in Guizhou Province, Southern China显示文摘Guizhou Province is an important karst area in the world and a fragile ecological area in China. Ecological risk assessment is very necessary to be conducted in this region. This study investigates different characteristics of the spatial-temporal changes of vegetation cover in Guizhou Province of Southern China using the data set of SPOT VEGETATION(1999–2015) at spatial resolution of 1-km and temporal resolution of 10-day. The coefficient of variation, the Theil-Sen median trend analysis, and the Mann-Kendall test are used to investigate the spatial-temporal change of vegetation cover and its future trend. Results show that: 1) the spatial distribution pattern of vegetation cover in Guizhou Plateau is high in the east whereas low in the west. The average annual normalized difference vegetation index(NDVI) from west to east is higher than that from south to north. 2) Average annual NDVI improved obviously in the past 17 years. The growth rate of average annual NDVI is 0.028/10 yr, which is slower than that of vegetation in the country(0.048/10 yr) from 1998 to 2007. Average annual NDVI in karst area is lower than that in non-karst area. However, the growing rate of average annual NDVI in karst area(0.030/10 yr) is faster than that in non-karst area(0.023/10 yr), indicating that vegetation coverage increases more rapidly in karst area. 3) Vegetation coverage in the study area is stable overall, but fluctuates in the local scales. 4) Vegetation coverage presents a continuous increasing trend. The Hurst exponent of NDVI in different vegetation types has an obvious threshold in various elevations. 5) The proportion of vegetation cover with sustainable increase is higher than that of vegetation cover with sustainable decrease. The improvement in vegetation cover may expand to most parts of the study area.TIAN Yichao BAI Xiaoyong WANG Shijie QIN Luoyi LI Yue 2017Chinese Geographical Science2017,27,1:21

7The PI3K/Akt/GSK-3β/ROS/eIF2B pathway promotes breast cancer growth and metastasis via suppression of NK cell cytotoxicity and tumor cell susceptibility显示文摘Objective: To examine the effect of pSer9-GSK-3β on breast cancer and to determine whether the underlying metabolic and immunological mechanism is associated with ROS/eIF2B and natural killer(NK) cells.Methods: We employed TWS119 to inactivate GSK-3β by phosphorylating Ser9 and explored its effect on breast cancer and NK cells. The expression of GSK-3β, natural killer group 2 member D(NKG2D) ligands, eIF2B was quantified by PCR and Western blot. We measured intracellular reactive oxygen species(ROS) and mitochondrial ROS using DCFH-DA and MitoSOX^(TM) probe,respectively, and conducted quantitative analysis of cellular respiration on 4T1 cells with mitochondrial respiratory chain complex Ⅰ/Ⅲ kits.Results: Our investigation revealed that TWS119 downregulated NKG2D ligands(H60 a and Rae1), suppressed the cytotoxicity of NK cells, and promoted the migration of 4T1 murine breast cancer cells. Nevertheless, LY290042, which attenuates p-GSK-3β formation by inhibiting the PI3K/Akt pathway, reversed these effects. We also found that higher expression of p Ser9-GSK-3β induced higher levels of ROS, and observed that abnormality of mitochondrial respiratory chain complex Ⅰ/Ⅲ function induced the dysfunction of GSK-3β-induced electron transport chain, naturally disturbing the ROS level. In addition, the expression of NOX3 and NOX4 was significantly up-regulated, which affected the generation of ROS and associated with the metastasis of breast cancer. Furthermore, we found that the expression of pSer535-eIF2B promoted the expression of NKG2D ligands(Mult-1 and Rae1) following by expression of pSer9-GSK-3β and generation of ROS.Conclusions: The PI3K/Akt/GSK-3β/ROS/eIF2B pathway could regulate NK cell activity and sensitivity of tumor cells to NK cells,which resulted in breast cancer growth and lung metastasis. Thus, GSK-3β is a promising target of anti-tumor therapy.Fengjiao Jin Zhaozhen Wu Xiao Hu Jiahui Zhang Zihe Gao Xiao Han Junfang Qin Chen Li Yue Wang 2019Cancer Biology & Medicine2019,16,1:20
8Carbonate-salt-based composite materials for medium- and high-temperature thermal energy storage显示文摘This paper discusses composite materials based on inorganic salts for medium- and high-temperature thermal energy storage application.The composites consist of a phase change material(PCM),a ceramic material,and a high thermal conductivity material.The ceramic material forms a microstructural skeleton for encapsulation of the PCM and structural stability of the composites;the high thermal conductivity material enhances the overall thermal conductivity of the composites.Using a eutectic salt of lithium and sodium carbonates as the PCM,magnesium oxide as the ceramic skeleton,and either graphite flakes or carbon nanotubes as the thermal conductivity enhancer,we produced composites with good physical and chemical stability and high thermal conductivity.We found that the wettability of the molten salt on the ceramic and carbon materials significantly affects the microstructure of the composites.Zhiwei Ge Feng Ye Hui Cao Guanghui Leng Yue Qin Yulong Ding 2014Particuology2014,12,4:19
9Isolation and Characterization of an Algicidal Bacterium Indigenous to Lake Taihu with a Red Pigment able to Lyse Microcystis aeruginosa显示文摘Objective To isolate and characterize indigenous algicidal bacteria and their algae-lysing compounds active against Microcystis aeruginosa, strains TH1, TH2, and FACHB 905. Methods The bacteria were identified using the Biolog automated microbial identification system and 16S rDNA sequence analysis. The algae-lysing compounds were isolated and purified by silica gel column chromatography and reverse-phase high performance liquid chromatography. Their structures were confirmed by Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FT-IR) spectroscopy. Algae-lysing activity was observed using microscopy. Results The algae-lysing bacterium LTH-2 isolated from Lake Taihu was identified as Serratia marcescens. Strain LTH-2 secreted a red pigment identified as prodigiosin (C 20 H 25 N 3 O), which showed strong lytic activity with algal strains M. aeruginosa TH1, TH2, and FACHB 905 in a concentration-dependent manner. The 50% inhibitory concentration (IC 50 ) of prodigiosin with the algal strains was 4.8 (±0.4)×10 -2 μg/mL, 8.9 (±1.1)×10-2 μg/mL, and 1.7 (±0.1)×10 -1 μg/mL in 24 h, respectively. Conclusion The bacterium LTH-2 and its pigment had strong Microcystis-lysing activity probably related to damage of cell membranes. The bacterium LTH-2 and its red pigment are potentially useful for regulating blooms of harmful M. aeruginosa.YANG Fei WEI Hai Yan LI Xiao Qin LI Yun Hui LI Xiao Bo YIN Li Hong PU Yue Pu 2013Biomedical and Environmental Sciences2013,26,2:19

13Expression of lens-related microRNAs in transparent infant lenses and congenital cataract显示文摘AIM:To identify the expression of lens-related micro RNAs(miRNAs)in the central epithelium of transparent infant lenses and congenital cataract. METHODS:Lens-related mi RNAs were retrieved from Pub Med database. The expression levels of these mi RNAs in transparent infant lenses and congenital cataract were determined by stem-loop reverse transcription-polymerase chain reaction(RT-PCR). mi Randa algorithm was used to predict the target genes of these differentially expressed mi RNAs. The target m RNA was validated.RESULTS:Six lens-related mi RNAs were retrieved from screening Pub Med database. The most abundant mi RNA in transparent infant lenses according to stem-loop RT-PCR was mi R-184. miR-182 was up-regulated in congenital cataract. Contrarily,miR-204 and miR-124 was down-regulated.mi R-204 exhibited a more significant decrease in expression than mi R-124. In addition,Meis2 was predicted to be the target of mi R-204 using mi Randa algorithm. mi R-204mimic/antagomir transfection experiments suggested the negative correlation between the expression of mi R-204 and Meis2.CONCLUSION:The expression levels of miR-182,miR-204 and mi R-124 differ between the central epithelium of transparent infant lens and congenital cataract,suggesting their involvement in the pathogenesis of congenital cataract. miR-204 may act via silencing Meis2 to regulate lens development and congenital cataract formation.Chang-Rui Wu Min Ye Li Qin Yue Yin Cheng Pei 2017International Journal of Ophthalmology(English edition)2017,10,3:11
14The Effects of Demographic Features on Differences in Sensitivity between PCL-C and SCL-90 Scores in a Follow-up Study in Secondary School Students in the Wenchuan Earthquake Region显示文摘Objective To analyze the sensitivity of effect factors between the PCL‐C and the SCL‐90,to provide evidence for social psychological crisis screening and post‐trauma interventions.Methods We administered the PCL‐C and SCL‐90 to screen for PTSD and other psychological problems among students who survived the disaster and continued their school studies.The surveys were carried out 3,6,9,and 12 months after the earthquake.A bivariate 2‐level logistic model was used to explore the different levels of sensitivity among students.The factors influencing the relationships between PTSD and depression,and between PTSD and anxiety were examined.Results We analyzed data from 1 677 students,revealing that female students in higher grades were more likely to exhibit symptoms of depression,rather than PTSD,compared with the control group (males in lower grades),and the difference was significant (P<0.05).In contrast,ethnic minorities were more likely to exhibit PTSD symptoms compared to the others.In addition,female students were more likely to exhibit symptoms of anxiety than PTSD.Other effects that did not reach statistical significance were suggested to have a similar influence on PTSD,depression,and anxiety.Conclusion After a natural disaster,specific aspects of depression and anxiety should be examined,avoiding an overemphasis on PTSD in social psychological crisis interventions.HOU Feng Su LI Ting LI Juan HU Xiao Qin LIU Zhi Yue YUAN Ping 2011Biomedical and Environmental Sciences2011,24,6:11
15Expert consensus on the evaluation and diagnosis of combat injuries of the Chinese People's Liberation Army显示文摘The accurate assessment and diagnosis of combat injuries are the basis for triage and treatment of combat casualties. A consensus on the assessment and diagnosis of combat injuries was made and discussed at the second annual meeting of the Professional Committee on Disaster Medicine of the Chinese People's Liberation Army(PLA). In this consensus agreement, the massive hemorrhage, airway, respiration, circulation and hypothermia(MARCH) algorithm, which is a simple triage and rapid treatment and field triage score, was recommended to assess combat casualties during the first-aid stage, whereas the abbreviated scoring method for combat casualty and the MARCH algorithm were recommended to assess combat casualties in level Ⅱ facilities. In level Ⅲ facilities, combined measures, including a history inquiry, thorough physical examination, laboratory examination, X-ray, and ultrasound examination, were recommended for the diagnosis of combat casualties. In addition, corresponding methods were recommended for the recognition of casualties needing massive transfusions, assessment of firearm wounds, evaluation of mangled extremities, and assessment of injury severity in this consensus.Zhao-wen Zong Lian-yang Zhang Hao Qin Si-xu Chen Lin Zhang Lei Yang Xiao-xue Li Quan-wei Bao Dao-cheng Liu Si-hao He Yue Shen Rong Zhang Yu-feng Zhao Xiao-zheng Zhong representing the PLA Professional Committee and Youth Committee on Disaster Medicine 2018Military Medical Research2018,5,3:10

20Nanoparticle-immersed paper imprinting mass spectrometry imaging reveals uptake and translocation mechanism of pesticides in plants显示文摘Design and discovery of carrier-mediated modified pesticides are vital for reducing pesticide dosage and increasing utilization,yet it remains a great challenge due to limited insights into plant translocation mechanisms.Nanostructure/nanoparticle assisted laser desorption/ionization strategy has established itself as a preferential analytical tool for biological tissue analysis,whereas potential applications in plant sciences are hindered with regard to the inability to slice plant leaves and petals.Herein,we report gold nanoparticle(AuNP)-immersed paper imprinting mass spectrometry imaging(MSI)for the spatiotemporal visualization of pesticide translocation in plant leaves.This approach plays a dual role in preserving spatial information and improving ionization efficiency for pesticides regardless of imaging artifacts due to homogenous AuNP deposition.Using this MSI platform,we proposed the elaborate plant translocation mechanism of agrochemicals for the first time,which is currently poorly understood.The dynamic processes of carrier-mediated pesticides can be clearly visualized,including crossing of plasma membranes by transporters,translocation downward in stems through the phloem,diffusion to the xylem and,conversely,accumulation at margins of the treated leaves.Moreover,this AuNP-assisted paper imprinting method could be highly compatible with laser-based MSI instruments,expediting researches across a broad range of fields,especially in nanomaterial development and life sciences.Xinzhou Wu Run Qin Hanxiang Wu Guangkai Yao Yue Zhang Ping Li Yizhu Xu Zhixiang Zhang Zhibin Yin Hanhong Xu 2020Nano Research2020,13,3:8
