| 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 |

| 3 | Air pollution characteristics and their relationship with emissions and meteorology in the Yangtze River Delta region during 2014–2016显示文摘With rapid economic growth and urbanization, the Yangtze River Delta(YRD) region in China has experienced serious air pollution challenges. In this study, we analyzed the air pollution characteristics and their relationship with emissions and meteorology in the YRD region during 2014–2016. In recent years, the concentrations of all air pollutants, except O3,decreased. Spatially, the PM2.5, PM10, SO2, and CO concentrations were higher in the northern YRD region, and NO2 and O3 were higher in the central YRD region. Based on the number of non-attainment days(i.e., days with air quality index greater than 100), PM2.5 was the largest contributor to air pollution in the YRD region, followed by O3, PM10, and NO2.However, particulate matter pollution has declined gradually, while O3 pollution worsened.Meteorological conditions mainly influenced day-to-day variations in pollutant concentrations. PM2.5 concentration was inversely related to wind speed, while O3 concentration was positively correlated with temperature and negatively correlated with relative humidity.The air quality improvement in recent years was mainly attributed to emission reductions.During 2014–2016, PM2.5, PM10, SO2, NOx, CO, NH3, and volatile organic compound(VOC)emissions in the YRD region were reduced by 26.3%, 29.2%, 32.4%, 8.1%, 15.9%, 4.5%, and0.3%, respectively. Regional transport also contributed to the air pollution. During regional haze periods, pollutants from North China and East China aggravated the pollution in the YRD region. Our findings suggest that emission reduction and regional joint prevention and control helped to improve the air quality in the YRD region. | Tao Ma Fengkui Duan Kebin He Yu Qin Dan Tong Guannan Geng Xuyan Liu Hui Li Shuo Yang Siqi Ye Beiyao Xu Qiang Zhang Yongliang Ma | 2019 | Journal of Environmental Sciences2019，31，9： | 26 |
| 4 | Monitoring lake changes of Qinghai-Tibetan Plateau over the past 30 years using satellite remote sensing data显示文摘During the years 2006–2009,lakes in the Qinghai-Tibetan Plateau(QTP)were investigated using satellite remote sensing strategies.We report the results of this investigation as well as follow-up research and expanded work.For the investigation,we mainly focused on lakes whose areas are more than 1 km2.The remote sensing data that we used included 408 scenes of CBERS CCD images and 5 scenes of Landsat ETM?images in Qinghai Province and Tibet Autonomous Region.All these data were acquired around years 2005–2006.Besides remote sensing images,we also collected 1,259 topographic maps.Numbers and areas of lakes were analyzed statistically,which were then compared with those coming from the first lake investigation(implemented between the1960s and 1980s).According to our investigation,up to and around year 2005–2006,the total number of lakes in the QTP was 1,055(222 in Qinghai and 833 in Tibet),accounting for more than 30%of that of China.Thirty newborn lakes with area[1 km2were found,and 5 dead lakes with initial area[1 km2were also found.Among those 13 big lakes([500 km2),Yamzhog Yumco had seriously shrunk,and it has continued to shrink in recent years;Qinghai Lake had shrunk during the period,but some new researches indicated that it has been expanding since the year 2004;Siling Co,Nam Co,and Chibuzhang Co had expanded in the period.We divided the newborn lakes into six categories according to their forming reasons,including river expansion,wetland conversion,etc.The changes of natural conditions led to the death of four lakes,and human exploitation was the main reason for the death of Dalianhai Lake in Qinghai.We picked out three regions which were sensitive to the change of climate and ecological environment:Nagqu Region,Kekexili Region,and the source area of the Yellow River(SAYR).Lakes in both Nagqu and Kekexili have been expanded;meanwhile,most lakes in the SAYR have obviously been shrunk.These regional patterns of lake changes were highly related to variations of temperature,glacier,precipitation,and evaporation.Our investigation and analysis will provide references for researches related to lake changes in the QTP and the response to climate fluctuations. | Wei Wan Pengfeng Xiao Xuezhi Feng Hui Li Ronghua Ma Hongtao Duan Limin Zhao | 2014 | Chinese Science Bulletin2014，59，10： | 22 |
| 5 | Factors Affecting Sensory Quality of Cooked japonica Rice显示文摘The sensory quality of cooked rice is an important factor in determining its market price, as well as consumer acceptance and breeding efforts aimed at improvement of rice grain quality. In this study,the sensory quality and physicochemical properties of three japonica rice varieties harvested in two different growing locations(Xiangshui and Hangzhou of China) were compared to determine the most important factors affecting the sensory quality. All the three varieties had higher scores for overall sensory quality in Xiangshui than in Hangzhou, indicating that the growing location is a key factor in determining the sensory quality of cooked japonica rice. In addition to growing location, variety(genotype) also had an important effect. Longdao 18 scored the highest for overall sensory quality in the two locations, whereas Longdao 30 had the lowest score in Xiangshui, and both Longdao 20 and Longdao 30 had the lowest scores in Hangzhou. Many physicochemical properties, such as apparent amylose content, protein content, thermal properties and free amino acid contents, showed significant differences between the two locations. Correlation analysis showed that apparent amylose content and protein content had contrasting effects on all the sensory attributes. The overall sensory quality was negatively correlated with protein content(r =-0.89, P < 0.01) and positively correlated with gel hardness(r = 0.91, P < 0.01),indicating that the protein content and hardness are important physicochemical properties for predicting the sensory quality of japonica rice. These findings will provide guidance for selection from the diverse genotypes available to develop new varieties with the desired eating and cooking quality. | XU Yanjie YING Yining OUYANG Shuhong DUAN Xiaoliang SUN Hui JIANG Shukun SUN Shichen BAO Jinsong | 2018 | Rice science2018，25，6： | 23 |
| 6 | Comparative analysis of twenty-five compounds in different parts of Astragalus membranaceus var.mongholicus and Astragalus membranaceus by UPLC-MS/MS显示文摘As a traditional Chinese medicine,the root of Astragalus membranaceus var.mongholicus(AMM)or A.membranaceus(AM)has been widely used in China and other Asian countries for thousands of years.Till now,the flavonoids,phenolic acids and saponins are considered as the main active components contributing to their therapeutic effect in these plants.In order to clarify the distribution and contents of these compounds in different organs of these plants,a rapid and sensitive analytical method for simultaneous determination of 25 active compounds including seven types(i.e.dihydroflavones,isoflavane,isoflavones,flavones,pterocarpans,phenolic acid and saponins)within 10 min was established using ultra-pressure liquid chromatography coupled with tandem mass spectrometry(UPLCeMS/MS).Then,the established method was fully validated and successfully applied to the determination of the contents of these analytes in different parts(root,rhizome,stem,leaf and flower)of AMM and AM.The results indicated that the contents of the same type of compounds in two different species plants were significantly different.Moreover,the obvious differences were also found for the distribution and contents of different type of compounds in five organs of the same species.The present study could provide necessary information for the rational development and utilization of AMM and AM resource. | Yuan Li Sheng Guo Yue Zhu Hui Yan Da-Wei Qian Han-Qing Wang Jian-Qiang Yu Jin-Ao Duan | 2019 | Journal of Pharmaceutical Analysis2019，9，6： | 23 |

| 12 | Designing solid-state interfaces on lithium-metal anodes: a review显示文摘Li-metal anodes are one of the most promising energy storage systems that can considerably exceed the current technology to meet the ever-increasing demand of power applications. The apparent cycling performances and dendrite challenges of Li-metal anodes are highly influenced by the interface layer on the Li-metal anode because the intrinsic high reactivity of metallic Li results in an inevitable solid-state interface layer between the Li-metal and electrolytes. In this review, we summarize the recent progress on the interfacial chemistry regarding the interactions between electrolytes and ion migration through dynamic interfaces. The critical factors that affect the interface formation for constructing a stable interface with a low resistance are reviewed. Moreover, we review emerging strategies for rationally designing multiple-structured solid-state electrolytes and their interfaces, including the interfacial properties within hybrid electrolytes and the solid electrolyte/electrode interface. Finally, we present scientific issues and perspectives associated with Li-metal anode interfaces toward a practical Li-metal battery. | Chen-Zi Zhao Hui Duan Jia-Qi Huang Juan Zhang Qiang Zhang Yu-Guo Guo Li-Jun Wan | 2019 | Science China Chemistry2019，62，10： | 14 |
| 13 | Preparation, characterization and salt-resistance of a coal based super absorbent composite显示文摘Potassium humate was extracted from brown coal. A novel super absorbent composite, poly (acrylic acid-co-acryla-mide)/potassium humate (PAA-AM/KHA), was prepared by graft polymerization of acrylic acid, acrylamide and coal based potas-sium humate using N, N’-methylenebisacrylamide as a crosslinker and potassium peroxydisulfate as an initiator. The effects of reaction temperature, degree of neutralization of the poly (acrylic acid) and the amounts of crosslinker, initiator and potassium hu-mate were investigated. Salt resistance tests were also carried out. The composite prepared under optimal conditions had a potas-sium humate content of 10% and exhibited a water absorption of 770 g/g in distilled water, and 349, 286 and 41 g/g in 0.5 mol/L KCl, MgCl2 and AlCl3 solutions respectively. The results indicate that the salt resistance of PAA-AM/KHA was superior to that of poly (acrylic acid-co-acrylamide) because of the collaborative effect of functional groups of the coal based potassium humate. The PAA-AM/KHA micro powder was characterized by IR spectroscopy and the micrographic surface was characterized by scanning electron microscopy. Introduction of potassium humate into the poly (acrylic acid-co-acrylamide) structure creates a composite more suitable for use as a water-managing material in the renewal of arid and desert environments. The salt resisting property of the composite is improved, production costs are reduced and the growth stimulant effect is still present. | CHU Mo, HUANG Zhanbin, XU Bang, FANG Tao, DUAN Hui School of Chemical and Environmental Engineering, China University of Mining & Technology, Beijing 100083, China | 2010 | Mining Science and Technology2010，20，6： | 13 |

| 15 | Increase of TNFα-stimulated Osteoarthritic Chondrocytes Apoptosis and Decrease of Matrix Metalloproteinases 9 by NF-κB Inhibition显示文摘Objective To investigate the in vitro effect of caffeic acid phenethyl ester(CAPE),a NF-κB inhibitor,on the apoptosis of osteoarthritic(OA)chondrocytes and on the regulation of the gelatinases matrix metalloproteinase 2(MMP-2)and matrix metalloproteinase 9(MMP-9).Methods Annexin V-FITC/propidium iodide(PI)labeling and western blotting were used to observe and determine the apoptosis in TNFα-stimulated primary cultured osteoarthritic chondrocytes.Also,gelatin zymography was applied to examine MMP-2 and MMP-9 activities in supernatants.Results It was confirmed by both flow cytometry and western blotting that chondrocytes from OA patients have an apoptotic background.Use of CAPE in combination with 10 ng/mL of TNFα for 24 h facilitated the apoptosis.MMP-9 in the supernatant could be autoactivated(from proMMP-9 to active MMP-9),and the physiologic calcium concentration(2.5 mmol/L)could delay the autoactivation of MMP-9.The activities of MMP-2 and MMP-9 in the fresh supernatant increased significantly in response to stimulation by 10 ng/mL of TNFα for 24 h.The stimulatory effect of TNFα just on proMMP-9 was counteracted significantly by CAPE.Conclusion NF-κB could prevent chondrocytes apoptosis though its activation was attributed to the increase of proMMP-9 activity induced by TNFα(a pro-apoptotic factor).Therefore,therapeutic NF-κB inhibitor was a 'double-edged swords' to the apoptosis of chondrocytes and the secretion of MMP-9. | WANG Yan LI De Ling ZHANG Xin Bo DUAN Yuan Hui WU Zhi Hong HAO Dong Sheng CHEN Bao Sheng QIU Gui Xing | 2013 | Biomedical and Environmental Sciences2013，26，4： | 13 |

| 17 | Effect of 5-FU on modulation of disarrangement of immune-associated cytokines in experimental acute pancreatitis显示文摘AIM:To investigate the effects of 5-Fluorouracil (5-FU) on modulation of pro-inflammatory and anti-inflammatory cytokines in acute pancreatitis and the mechanism of it in the treatment of acute pancreatitis.METHODS: Male Sprague Dawley rats were assigned to 3 Groups: Group A, sham operated rats as controls (n=7); Group B, acute pancreatitis induced by ductal injection with 5% sodium cholate at a volume of 1.0 mL/kg without any other treatment; Group C, after the pancreatitis was induced as in Group B, the rats were injected intravenously with 5-FU 40 mg/kg. The animals in Groups B and C were killed at 2, 6 and 24 h after operation (n=7), and blood samples were taken for measurement of tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), interleukin-6 (IL-6) (by bioas-say), and interleukin-10 (IL-10), transforming growth factor-β (TGF-β) (by ELISA). The wet weight of pancreatic tissue, serum amylase levels and white blood cells were also measured.RESULTS: Four rats in Group B and one in Group C died after pancreatitis was induced. Both pro-inflammatory cytokines (TNF-α, IL-1, IL-6) at the 2 and 6 h period and the anti-inflammatory cytokines (IL-10, TGF-β) at 24 h increased signif icantly (P<0.05) in rats of Group B. After treatment with 5-FU, TNF-α, IL-1, and IL-6 in serum of rats of Group C were inhibited at 2 and 6 h after operation (P<0.05), and IL-10, TGF-β were inhibited at 24 h compared to Group B (P<0.05). Obvious improvements in the severity of the acute pancreatitis, including the amylase levels, wet weight of pancreatic tissue and neutrophil counts, were also observed after treatment with 5-FU.CONCLUSION: 5-FU is an anti-metabolic and immu-nosuppressive agent which can minimize the abnormal immune cytokine response and relieve the pathophysiological disorders associated with experimental acute pancreatitis. | Xiao-Li Chen Sang-Zhu Ciren Hui Zhang Li-Geng Duan Alexander J Wesley | 2009 | World Journal of Gastroenterology2009，15，16： | 10 |
| 18 | Changes in Climate Factors and Extreme Climate Events in South China during 1961-2010显示文摘Daily climate data at 110 stations during 1961-2010 were selected to examine the changing characteristics of climate factors and extreme climate events in South China. The annual mean surface air temperature has increased significantly by 0.16℃ per decade, most notably in the Pearl River Delta and in winter. The increase rate of the annual extreme minimum temperature (0.48℃ per decade) is over twice that of the annual extreme maximum temperature (0.20℃ per decade), and the increase of the mean temperature is mainly the result of the increase of the extreme minimum temperature. The increase rate of high-temperature days (1.1 d per decade) is close to the decrease rate of low-temperature days (-1.3 d per decade). The rainfall has not shown any significant trend, but the number of rainy days has decreased and the rain intensity has increased. The regional mean sunshine duration has a significant decreasing trend of -40.9 h per decade, and the number of hazy days has a significant increasing trend of 6.3 d per decade. The decrease of sunshine duration is mainly caused by the increase of total cloud, not by the increase of hazy days in South China. Both the regional mean pan evaporation and mean wind speed have significant decreasing trends of -65.9 mm per decade and -0.11 m s-1 per decade, respectively. The decrease of both sunshine duration and mean wind speed plays an important role in the decrease of pan evaporation. The number of landing tropical cyclones has an insignificant decreasing trend of -0.6 per decade, but their intensities show a weak increasing trend. The formation location of tropical cyclones landing in South China has converged towards 10-19°N, and the landing position has shown a northward trend. The date of the first landfall tropical cyclone postpones 1.8 d per decade, and the date of the last landfall advances 3.6 d per decade, resulting in reduction of the typhoon season by 5.4 d per decade. | DU Yao-Dong AI Hui DUAN Hai-Lai HU Ya-Min WANG Xian-Wei HE Jian WU Hong-Yu WU Xiao-Xuan | 2013 | Advances in Climate Change Research2013，4，1： | 9 |
| 19 | Physicochemical analysis of individual atmospheric fine particles based on effective surface-enhanced Raman spectroscopy显示文摘Fine particles associated with haze pollution threaten the health of more than 400 million people in China. It is therefore of great importance to thoroughly investigate and understand their composition. To determine the physicochemical properties in atmospheric fine particles at the micrometer level, we described a sensitive and feasible surface-enhanced Raman scattering(SERS) method using Ag foil as a substrate. This novel method enhanced the Raman signal intensities up to 10,000 a.u. for ν(NO_3^-) in fine particles.The SERS effect of Ag foil was further studied experimentally and theoretically and found to have an enhancement factor of the order of ~10~4. Size-fractionated real particle samples with aerodynamic diameters of 0.4–2.5 μm were successfully collected on a heavy haze day,allowing ready observation of morphology and identification of chemical components, such as soot, nitrates, and sulfates. These results suggest that the Ag-foil-based SERS technique can be effectively used to determine the microscopic characteristics of individual fine particles, which will help to understand haze formation mechanisms and formulate governance policies. | Zhenli Sun Fengkui Duan Kebin He Jingjing Du Liu Yang Hui Li Tao Ma Shuo Yang | 2019 | Journal of Environmental Sciences2019，31，1： | 9 |
