1Anthropogenic emission inventories in China:a review显示文摘The development of reliable anthropogenic emission inventories is essential for both understanding the sources of air pollution and designing effective air-pollution-control measures in China. However, it is challenging to quantify emissions in China accurately, given the variety of contributing sources, the complexity of the technology mix and the lack of reliable measurements. Over the last two decades,tremendous efforts have been made to improve the accuracy of emission inventories, and significant improvements have been realized. More reliable statistics and survey-based data have been used to reduce the uncertainties in activity rates and technology distributions. Local emission factors and source profiles covering various sources have been measured and reported. Based on these local databases, improved emission inventory models have been developed for power plants, large industrial plants and the residential,transportation and agricultural sectors. In this paper, we review the progress that has been made in developing inventories of anthropogenic emissions in China. We first highlight the major updates that have been made to emission inventory models and the underlying data by source category. We then summarize the sector-based estimates of emissions of different species contained in current inventories. The progress that has been made in the development of model-ready emissions is also presented. Finally, we suggest future directions for further improving the accuracy of emission inventories in China.Meng Li Huan Liu Guannan Geng Chaopeng Hong Fei Liu Yu Song Dan Tong Bo Zheng Hongyang Cui Hanyang Man Qiang Zhang Kebin He 2017National Science Review2017,4,6:100

32018 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
4Contrasting trends of PM2.5 and surface-ozone concentrations in China from 2013 to 2017显示文摘Although much attention has been paid to investigating and controlling air pollution in China,the trends of air-pollutant concentrations on a national scale have remained unclear.Here,we quantitatively investigated the variation of air pollutants in China using long-term comprehensive data sets from 2013 to 2017,during which Chinese government made major efforts to reduce anthropogenic emission in polluted regions.Our results show a significant decreasing trend in the PM2.5 concentration in heavily polluted regions of eastern China,with an annual decrease of〜7%compared with measurements in 2013.The measured decreased concentrations of SO2>NO2 and CO(a proxy for anthropogenic volatile organic compounds)could explain a large fraction of the decreased PM2.5 concentrations in different regions.As a consequence;the heavily polluted days decreased significantly in corresponding regions.Concentrations of organic aerosol;nitrate;sulfate,ammonium and chloride measured in urban Beijing revealed a remarkable reduction from 2013 to 2017;connecting the decreases in aerosol precursors with corresponding chemical components closely.However;surface-ozone concentrations showed increasing trends in most urban stations from 2013 to 2017;which indicates stronger photochemical pollution.The boundary-layer height in capital c让ies of eastern China showed no significant trends over the Beijing-Tianjin-Hebei,Yangtze River Delta and Pearl River Delta regions from 2013 to 2017;which confirmed the reduction in anthropogenic emissions.Our results demonstrated that the Chinese government was successful in the reduction of particulate matter in urban areas from 2013 to 2017,although the ozone concentration has increased significantly;suggesting a more complex mechanism of improving Chinese air quality in the future.Yonghong Wang Wenkang Gao Shuai Wang Tao Song Zhengyu Gong Dongsheng Ji Lili Wang Zirui Liu Guiqian Tang Yanfeng Huo Shili Tian Jiayun Li Mingge Li Yuan Yang Biwu Chu Tuukka Petaja Veli-Matti Kerminen Hong He Jiming Hao Markku Kulmala Yuesi Wang Yuanhang Zhang 2020National Science Review2020,7,8:51

6Trends in Lipids Level and Dyslipidemia among Chinese Adults, 2002-2015显示文摘Objective To investigate the trends of lipid profiles and dyslipidemia among Chinese adults from 2002 to 2015.Methods Data were collected from three nationally representative cross-sectional surveys.Fasting venous blood samples were collected and serum lipids were tested by biochemical analysis and enzymatic determination.Lipid levels and the prevalence of dyslipidemia among adults were analyzed with complex sampling weighting adjustment for age and gender.Results The weighted means of TC, TG, and LDL-c significantly increased linearly from 3.93, 1.12, and 2.12 mmol/L in 2002 to 4.59, 1.41, and 2.78 mmol/L in 2010 and then to 4.63, 1.47, and 2.87 mmol/L in 2015, respectively;by contrast, HDL-c levels decreased significantly from 1.30 mmol/L to 1.26 mmol/L over the same period.Similar trends in mean non-HDL-c and lipid-related ratios were observed.The weighted dyslipidemia prevalence linearly increased;in particular, hypercholesterolemia increased from 1.6% to 5.6% and then to 5.8%, hypertriglyceridemia increased from 5.7% to 13.6% and then to 15.0%, low HDL-c increased from 18.8% to 35.5% and then to 24.9%, and high LDL-c increased from 1.3% to 5.6% and then to 7.2%(P for trend <0.001).Conclusion Dyslipidemia increased among Chinese adults from 2002 to 2015.Development of a comprehensive strategy to decrease lipid levels in this population is urgently required.SONG Peng Kun MAN Qing Qing LI Hong PANG Shao Jie JIA Shan Shan LI Yu Qian HE Li ZHAO Wen Hua ZHANG Jian 2019Biomedical and Environmental Sciences2019,32,8:45
7Ganoderic acid hinders renal fibrosis via suppressing the TGF- β/Smad and MAPK signaling pathways显示文摘Renal fibrosis is considered as the pathway of almost all kinds of chronic kidney diseases(CKD)to the end stage of renal diseases(ESRD).Ganoderic acid(GA)is a group of lanostane triterpenes isolated from Ganoderma lucidum,which has shown a variety of pharmacological activities.In this study we investigated whether GA exerted antirenal fibrosis effect in a unilateral ureteral obstruction(UUO)mouse model.After UUO surgery,the mice were treated with GA(3.125,12.5,and 50 mg·kg^−1·d^−1,ip)for 7 or 14 days.Then the mice were sacrificed for collecting blood and kidneys.We showed that GA treatment dose-dependently attenuated UUO-induced tubular injury and renal fibrosis;GA(50 mg·kg^−1·d^−1)significantly ameliorated renal disfunction during fibrosis progression.We further revealed that GA treatment inhibited the extracellular matrix(ECM)deposition in the kidney by suppressing the expression of fibronectin,mainly through hindering the over activation of TGF-β/Smad signaling.On the other hand,GA treatment significantly decreased the expression of mesenchymal cell markers alpha-smooth muscle actin(α-SMA)and vimentin,and upregulated E-cadherin expression in the kidney,suggesting the suppression of tubular epithelial-mesenchymal transition(EMT)partially via inhibiting both TGF-β/Smad and MAPK(ERK,JNK,p38)signaling pathways.The inhibitory effects of GA on TGF-β/Smad and MAPK signaling pathways were confirmed in TGF-β1-stimulated HK-2 cell model.GA-A,a GA monomer,was identified as a potent inhibitor on renal fibrosis in vitro.These data demonstrate that GA or GA-A might be developed as a potential therapeutic agent in the treatment of renal fibrosis.Xiao-qiang Geng Ang Ma Jin-zhao He Liang Wang Ying-li Jia Guang-ying Shao Min Li Hong Zhou Shu-qian Lin Jian-hua Ran Bao-xue Yang 2020Acta Pharmacologica Sinica2020,41,5:43
8Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control.Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu 2021Science China(Life Sciences)2021,64,5:46
9Ecological Species Groups and Interspecific Association of Dominant Tree Species in Daiyun Mountain National Nature Reserve显示文摘Research on the ecological species groups and interspecific association of plant species are helpful to discover species coexistence processes and mechanisms, and to more fully understand plant community structure, function, and its taxonomy. However, little is known about the ecological species groups(ESG) and the interspecific association of dominant species in Daiyun Mountain National Nature Reserve of Fujian Province, China. Therefore, the main goal of this paper is to explore the ESG using maximal tree, and to analyze interspecific associations of 32 dominant species selected from 102 sample plots using the chi-square test. The results show that:(1) 32 dominant species have a significant overall positive interspecific association, which indicates that the natural forest in Daiyun Mountain National Nature Reserve is stable,(2) The species pairs with weak associations, non-associations and positiveassociations account for 10.88%, 29.64% and 59.48% of the total 496 species pairs respectively, which suggests that the population distributions of the dominant species investigated are relatively independent,(3) The following species pairs may be useful for practical application, , , , , , , and(4) The results of clustering analysis based on the maximal tree method indicates that the 32 dominant species can be divided into 3 ESGs when λ at 0.60, that is ESGⅠ{Pinus massoniana, Cunning hamia lanceolata}, ESG Ⅱ{P. taiwanensis, R. farrerae, Enkianthus quinqueflorus}, ESG Ⅲ {C. carlesii, A. chinensis, C. eyrei, Castanopsis fabri, C. fargesii, Schima superba, Machilus thunbergii, Rhododendron latoucheae}. The results may be used for the selection of afforestation tree species in South China Forest Areas and guide the natural management of plantations.SU Song-jin LIU Jin-fu HE Zhong-sheng ZHENG Shi-qun HONG Wei XU Dao-wei 2015Journal of Mountain Science2015,12,3:37
10Single-atom site catalysts for environmental catalysis显示文摘In recent decades,the environmental protection and long-term sustainability have become the focus of attention due to the increasing pollution generated by the intense industrialization.To overcome these issues,environmental catalysis has increasingly been used to solve the negative impact of pollutants emission on the global environment and human health.Supported platinum-metal-group(PGM)materials are commonly utilized as the state-of-the-art catalysts to eliminate gaseous pollutants but large quantities of PGMs are required.By comparison,single-atom site catalysts(SACs)have attracted much attention in catalysis owing to their 100%atom efficiency and unique catalytic performances towards various reactions.Over the past decade,we have witnessed burgeoning interests of SACs in heterogeneous catalysis.However,to the best of our knowledge,the systematic summary and analysis of SACs in catalytic elimination of environmental pollutants has not yet been reported.In this paper,we summarize and discuss the environmental catalysis applications of SACs.Particular focus was paid to automotive and stationary emission control,including model reaction(CO oxidation,NO reduction and hydrocarbon oxidation),overall reaction(three-way catalytic and diesel oxidation reaction),elimination of volatile organic compounds(formaldehyde,benzene,and toluene),and removal/decomposition of other pollutants(Hg0 and SO3).Perspectives related to further challenges,directions and design strategies of single-atom site catalysts in environmental catalysis were also provided.Ningqiang Zhang Chenliang Ye Han Yan Lingcong Li Hong He Dingsheng Wang Yadong Li 2020Nano Research2020,13,12:38

16ZIKA virus isolated from mosquitoes:a field and laboratory investigation in China,2016显示文摘A field investigation of arboviruses was conducted in Dejiang, Guizhou Province in the summer of 2016. A total of 8,795 mosquitoes, belonging to four species of three genera, and 1,300 midges were collected. The mosquito samples were identified on site according to their morphology, and the pooled samples were ground and centrifuged in the laboratory. The supernatant was incubated with mosquito tissue culture cells(C6/36) and mammalian cells(BHK-21) for virus isolation. The results indicated that 40%(3,540/8,795) were Anopheles sinensis, 30%(2,700/8,795) were Culex pipiens quinquefasciatus, and 29%(2,530/8,795)were Armigeres subbalbeatus. Furthermore, a total of eight virus isolates were obtained, and genome sequencing revealed two Zika viruses(ZIKVs) isolated from Culex pipiens quinquefasciatus and Armigeres subbalbeatus, respectively; three Japanese encephalitis viruses(JEVs) isolated from Culex pipiens quinquefasciatus; two Banna viruses(BAVs) isolated from Culex pipiens quinquefasciatus and Anopheles sinensis, respectively; and one densovirus(DNV) isolated from Culex pipiens quinquefasciatus.The ZIKVs isolated from the Culex pipiens quinquefasciatus and Armigeres subbalbeatus mosquitoes represent the first ZIKV isolates in China's Mainland. This discovery presents new challenges for the prevention and control of ZIKV in China, and prompts international cooperation on this global issue.Shihong Fu Song Song Hong Liu Yuanyuan Li Xiaolong Li Xiaoyan Gao Ziqian Xu Guoping Liu Dingming Wang Zhenzao Tian Jingzhu Zhou Ying He Wenwen Lei Huanyu Wang Bin Wang Xiaoqing Lu Guodong Liang 2017Science China(Life Sciences)2017,60,12:25
17HIF-1α induces VE-cadherin expression and modulates vasculogenic mimicry in esophageal carcinoma cells显示文摘AIM:To investigate whether hypoxia inducible factor(HIF)-1αmodulates vasculogenic mimicry(VM)by upregulating VE-cadherin expression in esophageal squamous cell carcinoma(ESCC).METHODS:Esophageal squamous cancer cell lines Eca109 and TE13 were transfected with plasmids harboring small interfering RNAs targeting HIF-1αor VEcadherin.The proliferation and invasion of esophageal carcinoma cells were detected by MTT and Transwell migration assays.The formation of tubular networks of cells was analyzed by 3D culture in vitro.BALB/c nude mice were used to observe xenograft tumor formation.The relationship between the expression of HIF-1αand VE-cadherin,ephrin A2(Eph A2)and laminin5γ2(LN5γ2)was measured by Western blot and real-time polymerase chain reaction.RESULTS:Knockdown of HIF-1αinhibited cell proliferation(32.3%±6.1%for Eca109 cells and 38.6%±6.8%for TE13 cells,P<0.05).Both Eca109 and TE13cells formed typical tubular networks.The number of tubular networks markedly decreased when HIF-1αor VE-cadherin was knocked down.Expression of VEcadherin,Eph A2 and LN5γ2 was dramatically inhibited,but the expression of matrix metalloproteinase 2 had no obvious change in HIF-1α-silenced cells.Knockdown of VE-cadherin significantly decreased expression of both Eph A2 and LN5γ2(P<0.05),while HIF-1αexpression was unchanged.The time for xenograft tumor formation was 6±1.2 d for Eca109 cells and Eca109cells transfected with HIF-1αNeo control short hairpin RNA(sh RNA)vector,and 8.4±2.1 d for Eca109 cells transfected with an sh RNA against HIF-1α.Knockdown of HIF-1αinhibited vasculogenic mimicry(VM)and tumorigenicity in vivo.CONCLUSION:HIF-1αmay modulate VM in ESCC by regulating VE-cadherin expression,which affects VM formation through Eph A2 and LN5γ2.Na-Na Tang Hong Zhu Hong-Jie Zhang Wei-Feng Zhang Hai-Lin Jin Lu Wang Pin Wang Gui-Jun He Bo Hao Rui-Hua Shi 2014World Journal of Gastroenterology2014,20,47:25
18Furazolidone-based triple and quadruple eradication therapy for Helicobacter pylori infection显示文摘AIM: To evaluate the efficacy of furazolidone-based triple and quadruple therapy in eradicating Helicobacter pylori(H. pylori) in a multi-center randomized controlled trial.METHODS: A total of 720 H. pylori positive patients with duodenal ulcer disease were enrolled at 10 different hospitals in Jiangxi province in China. The patients were randomly assigned to four treatment groups as follows: patients in Groups 1 and 3 received rabeprazole(10 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively; patients in Groups 2 and 4 received rabeprazole(10 mg), bismuth(220 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively. The primary outcome measure was H. pylori eradication rate 4 wk after treatment by intention-to-treat and per protocol analysis, while the secondary outcome measures were symptom and sign changes at the end of treatment and 4 wk after the end of treatment, as well as the proportion of patients who developed adverse events.RESULTS: The demographic data of the four groups were not significantly different. Overall, 666 patients completed the scheme and were re-assessed with the 13C-urea breath test. The intention-to-treat analysis of the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 74.44%, 82.78%, 78.89% and 86.11%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. According tothe per protocol analysis, the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 81.21%, 89.22%, 85.54% and 92.26%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. The number of adverse events was 15(8.3%), 16(8.9%), 15(8.3%) and 17(9.4%) in Groups 1, 2, 3 and 4, respectively, including dizziness, vomiting, diarrhea, nausea, skin rash, itchy skin, and malaise.

19Application of contrast-enhanced intraoperative ultrasonography in the decision-making about hepatocellular carcinoma operation显示文摘AIM:To evaluate the detection and differentiation ability of contrast-enhanced intraoperative ultrasonography(CE-IOUS) in hepatocellular carcinoma(HCC) operations.METHODS:Clinical data of 50 HCC patients were retrospective analyzed.The sensitivity,specificity,false negative and false positive rates of contrast enhanced magnetic resonance imaging(CE-MRI),IOUS and CEIOUS were calculated and compared.Surgical strategy changes due to CE-IOUS were analyzed.RESULTS:Lesions detected by CE-MRI,IOUS and CEIOUS were 60,97 and 85 respectively.The sensitivity,specificity,false negative rate,false positive rate of CEMRI were 98.2%,98.6%,98.6%,60.0%,respectively;for IOUS were 50.0%,90.9%,1.8%,1.4%,respectively;and for CE-IOUS were 1.4%,40.0%,50.0%,9.1%,respectively.The operation strategy of 9(9/50,18.0%) cases was changed according to the results of CE-IOUS.CONCLUSION:Compared with CE-MRI,CE-IOUS performs better in detection and differentiation of small metastasis and regenerative nodules.It plays an important role in the decision-making of HCC operation.Wu, Hong Lu, Qiang Luo, Yan He, Xian-Lu Zeng, Yong 2010World Journal of Gastroenterology2010,16,4:22
20Rural land use spatial allocation in the semiarid loess hilly area in China:Using a Particle Swarm Optimization model equipped with multi-objective optimization techniques显示文摘Semiarid loess hilly areas in China are enduring a series of environmental conflicts between urban expansion,cultivated land conservation,soil erosion and water shortage,and require land use allocation to reconcile these environmental conflicts.We argue that the optimized spatial allocation of rural land use can be achieved by a Particle Swarm Optimization (PSO) model in conjunction with multi-objective optimization techniques.Our study focuses on Yuzhong County of Gangsu Province in China,a typical catchment on the Loess Plateau,and proposes a land use spatial optimization model.The model maximizes land use suitability and spatial compactness based on a variety of constraints,e.g.optimal land use structure and restrictive areas,and employs an improved PSO algorithm equipped with a determinant initialization method and a dynamic weighted aggregation (DWA) method to obtain the optimized land use spatial pattern.The results suggest that (1) approximately 4% of land use should be reallocated and these changes would alleviate the environmental conflicts in the study area;(2) the major reshuffling is slope farmland and newly added construction and cultivated land,whereas the unchanged areas are largely forests and basic farmland;and (3) the PSO is capable of optimizing rural land use allocation,and the determinant initialization method and DWA can improve the performance of the PSO.LIU YaoLin LIU DianFeng LIU YanFang HE JianHua JIAO LiMin CHEN YiYun HONG XiaoFeng 2012Science China Earth Sciences2012,55,7:23
