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
2Injectable hydrogels for cartilage and bone tissue engineering显示文摘Tissue engineering has become a promising strategy for repairing damaged cartilage and bone tissue. Among the scaffolds for tissue-engineering applications, injectable hydrogels have demonstrated great potential for use as three-dimensional cell culture scaffolds in cartilage and bone tissue engineering, owing to their high water content, similarity to the natural extracellular matrix(ECM), porous framework for cell transplantation and proliferation, minimal invasive properties, and ability to match irregular defects. In this review, we describe the selection of appropriate biomaterials and fabrication methods to prepare novel injectable hydrogels for cartilage and bone tissue engineering. In addition, the biology of cartilage and the bony ECM is also summarized. Finally, future perspectives for injectable hydrogels in cartilage and bone tissue engineering are discussed.Mei Liu Xin Zeng Chao Ma Huan Yi Zeeshan Ali Xianbo Mou Song Li Yan Deng Nongyue He 2017Bone Research2017,5,2:54

4XingNaoJing injections protect against cerebral ischemia/reperfusion injury and alleviate blood-brain barrier disruption in rats, through an underlying mechanism of NLRP3 inflammasomes suppression显示文摘The aim of this study was to explore the neuroprotective effect and mechanism of XingNaoJing injections(XNJ) on cerebral ischemia injury and blood-brain barrier(BBB) disruption. Middle cerebral artery occlusion(MCAO) method was applicated to establish the model of cerebral ischemia/reperfusion(I/R) injury in rats. BBB permeability after I/R injury was assessed with the leaking amount of Evans Blue and the expression of occludin and ZO-1. The expression of NOD-like receptor family, pyrin domain containing(NLRP3) was checked to explore the inhibition of inflammation by XNJ. The results showed that XNJ could significantly increase the survival percent, decrease the infarct area and ameliorate neurological deficits and brain damage after I/R injury. Leaking amount of Evans Blue was reduced by XNJ, and the expression of tight junction protein, occludin and ZO-1 was also up-regulated by XNJ, which showed a role of protection on BBB disruption. The expression of NLRP3 was inhibited after exposure of XNJ, which was associated with inhibition of the inflammatory response. In summary, XNJ could suppress NLRP3 inflammasomes and improve BBB disruption and brain damage in rats after cerebral I/R injury, which provided a beneficial insight to further explore XNJ.QU Xiao-Yu ZHANG Yue-Ming TAO Li-Na GAO Huan ZHAI Jing-Hui SUN Jing-Meng SONG Yan-Qing ZHANG Si-Xi 2019Chinese Journal of Natural Medicines2019,17,7:20

6Coinfection with influenza A virus enhances SARS-CoV-2 infectivity显示文摘The upcoming flu season in the Northern Hemisphere merging with the current COVID-19 pandemic raises a potentially severe threat to public health.Through experimental coinfection with influenza A virus(IAV)and either pseudotyped or live SARS-CoV-2 virus,we found that IAV preinfection significantly promoted the infectivity of SARS-CoV-2 in a broad range of cell types.Remarkably,in vivo,increased SARS-CoV-2 viral load and more severe lung damage were observed in mice coinfected with IAV.Moreover,such enhancement of SARS-CoV-2 infectivity was not observed with several other respiratory viruses,likely due to a unique feature of IAV to elevate ACE2 expression.This study illustrates that IAV has a unique ability to aggravate SARS-CoV-2 infection,and thus,prevention of IAV infection is of great significance during the COVID-19 pandemic.Lei Bai Yongliang Zhao Jiazhen Dong Simeng Liang Ming Guo Xinjin Liu Xin Wang Zhixiang Huang Xiaoyi Sun Zhen Zhang Lianghui Dong Qianyun Liu Yucheng Zheng Danping Niu Min Xiang Kun Song Jiajie Ye Wenchao Zheng Zhidong Tang Mingliang Tang Yu Zhou Chao Shen Li Zhou Yu Chen Huan Yan Ke Lan Ke Xu 2021Cell Research2021,31,4:16
7The Prevalence of Nonalcoholic Fatty Liver Disease and its Association with Lifestyle/dietary Habits among University Faculty and Staff in Chengdu显示文摘Objective To investigate the prevalence of nonalcoholic fatty liver disease(NAFLD) in different university categories and its association with lifestyle/dietary habits.Methods A cross-sectional study was carried out on 9 378 faculty members and staff who participated in an annual health checkup at three universities selected by random cluster sampling.Demographic,anthropometric,biochemical indices and abdominal ultrasound measurements were collected.A nested case-control study was conducted with 200 NAFLD cases and 200 controls matched by gender,age(±3 years),and university.Results The overall prevalence of NAFLD was 10.3%(13.7% in males and 6.8% in females).The prevalence was significantly higher in the science and engineering university(22.1%) than in the comprehensive universities with(6.4%) and without(10.9%) medical colleges.Obesity/overweight,hyperlipidemia,diabetes mellitus,and family history of NAFLD were independently associated with higher risk of NAFLD,as were frequent consumption of desserts and salty/spicy foods.Using nutritional supplements was a protective factor against NAFLD.Intake of coarse cereals,potatoes,vegetables,fruits,and milk was significantly lower,and intake of red meat,viscera,candies and pastries,cooking oil,and total energy was significantly higher in participants with NAFLD than in controls.Conclusion Science and engineering university faculty and staff are key targets for NAFLD prevention.NAFLD is closely associated with age,gender,university type,metabolic diseases,and lifestyle/dietary habits.SHI Lei LIU Zhong Wu LI Yun GONG Cai ZHANG Huan SONG Li Juan HUANG Cheng Yu LI Ming 2012Biomedical and Environmental Sciences2012,25,4:16

9Identification of a Newly Isolated Getah Virus in the China-Laos Border,China显示文摘In this study, we isolated a virus strain(YN12031) from specimens of Armigeres subalbatus collected in the China-Laos border. BHK-21 cells infected with YN12031 exhibited an evident cytopathic effect(CPE) 32 h post-infection. The virus particles were spherical, 70 nm in diameter, and enveloped; they also featured surface fibers. Molecular genetic analysis revealed that YN12031 was closely related to alpha viruses such as Chikungunya virus and Sindbis virus, and located in the same clade as MM2021, the prototype of Getahvirus(GETV) isolated in Malaysia in 1955. Phylogenetic analysis of the E2 and capsid genes further revealed that YN12031 was located in the same clade as the Russian isolate LEIV/16275/Mag. Analysis of the homology of nucleotides and amino acids in the coding area and E2 gene demonstrated that the YN12031 isolated from the China-Laos border(tropical region) was related closest to the LEIV/16275/Mag isolate obtained in Russia(North frigid zone area) among other isolates studied. These results suggest that GETV can adapt to different geographical environments to propagate and evolve. Thus, strengthening the detection and monitoring of GETV and its related diseases is very crucial.LI Yuan Yuan FU Shi Hong GUO Xiao Fang LEI Wen Wen LI Xiao Long SONG Jing Dong CAO Lei GAO Xiao Yan LYU Zhi HE Ying WANG Huan Yu REN Xiao Jie ZHOU Hong Ning WANG Gui Qin LIANG Guo Dong 2017Biomedical and Environmental Sciences2017,30,3:12
10Low-Dimensional Halide Perovskites and Their Advanced Optoelectronic Applications显示文摘Metal halide perovskites are crystalline materials originally developed out of scientific curiosity. They have shown great potential as active materials in optoelectronic applications. In the last 6 years, their certified photovoltaic efficiencies have reached 22.1%. Compared to bulk halide perovskites, low-dimensional ones exhibited novel physical properties. The photoluminescence quantum yields of perovskite quantum dots are close to 100%. The external quantum efficiencies and current efficiencies of perovskite quantum dot light-emitting diodes have reached 8% and 43 cd A^(-1),respectively, and their nanowire lasers show ultralow-threshold room-temperature lasing with emission tunability and ease of synthesis. Perovskite nanowire photodetectors reached a responsivity of 10 A W^(-1)and a specific normalized detectivity of the order of 10^(12 )Jones. Different from most reported reviews focusing on photovoltaic applications, we summarize the rapid progress in the study of low-dimensional perovskite materials, as well as their promising applications in optoelectronic devices. In particular, we review the wide tunability of fabrication methods and the state-of-the-art research outputs of low-dimensional perovskite optoelectronic devices. Finally, the anticipated challenges and potential for this exciting research are proposed.Jian Zhang Xiaokun Yang Hui Deng Keke Qiao Umar Farooq Muhammad Ishaq Fei Yi Huan Liu Jiang Tang Haisheng Song 2017Nano-Micro Letters2017,9,3:10

17Association between Metabolic Syndrome and Carotid Atherosclerosis: A Cross-sectional Study in Northern China显示文摘Objective Increased carotid artery intima-media thickness(CIMT)and carotid plaque as manifestations of carotid atherosclerosis have been used as markers of cardiovascular disease(CVD).The components of metabolic syndrome(Met S)are linked to CVD,but the association between Met S and CVD is controversial.Methods A total of 8,933 Chinese adults aged 40 years or older from 2010 to 2014 were selected from the Jidong and Kailuan communities.Met S was defined by the International Diabetes Federation criteria.CIMT and carotid plaque were measured using color Doppler ultrasound.Logistic regression models were used to assess the association of Met S with carotid plaque and CIMT.Results Met S was found among 3,461(3,461/8,933)participants.The odds ratio and 95%confidence internal(CI)for carotid plaques in participants with Met S was 1.16(1.03-1.30).The risk of carotid plaques increased with the number of Met S components.The average CIMT was higher in participants with Met S(β=0.020,95%CI,0.014-0.027)and in participants with more Met S components.Conclusion Individuals with Met S are at an increased risk for carotid atherosclerosis compared to those without MetS.ZHOU Ping An ZHANG Chen Huan CHEN Yan Ru LI Dong SONG Dai Yu LIU Hua Min ZHOU Ming Yue SONG Guo Shun CHEN Sheng Yun 2019Biomedical and Environmental Sciences2019,32,12:6
18Pantograph-catenary electrical contact system of high-speed railways:recent progress,challenges,and outlooks显示文摘As the unique power entrance,the pantograph-catenary electrical contact system maintains the efficiency and reliability of power transmission for the high-speed train.Along with the fast development of high-speed railways all over the world,some commercialized lines are built for covering the remote places under harsh environment,especially in China;these environmental elements including wind,sand,rain,thunder,ice and snow need to be considered during the design of the pantograph-catenary system.The pantograph-catenary system includes the pantograph,the contact wire and the interface—pantograph slide.As the key component,this pantograph slide plays a critical role in reliable power transmission under dynamic condition.The fundamental material characteristics of the pantograph slide and contact wire such as electrical conductivity,impact resistance,wear resistance,etc.,directly determine the sliding electrical contact performance of the pantograph-catenary system;meanwhile,different detection methods of the pantograph-catenary system are crucial for the reliability of service and maintenance.In addition,the challenges brought from extreme operational conditions are discussed,taking the Sichuan-Tibet Railway currently under construction as a special example with the high-altitude climate.The outlook for developing the ultra-high-speed train equipped with the novel pantograph-catenary system which can address the harsher operational environment is also involved.This paper has provided a comprehensive review of the high-speed railway pantograph-catenary systems,including its progress,challenges,outlooks in the history and future.Guangning Wu Keliang Dong Zhilei Xu Song Xiao Wenfu Wei Huan Chen Jie Li Zhanglin Huang Jingwei Li Guoqiang Gao Guozheng Kang Chuanjun Tu Xingyi Huang 2022Railway Engineering Science2022,30,4:5
19Highly Sensitive and Specific Monoclonal Antibody-Based Serological Methods for Rice Ragged Stunt Virus Detection in Rice Plants and Rice Brown Planthopper Vectors显示文摘Rice ragged stunt virus(RRSV) is a serious rice disease in Asia, causing serious yield losses on rice. The capsid protein(CP) gene of the major outer capsid protein of RRSV was expressed in Escherichia coli BL21(DE3) using the pMAL-C2 X expression vector. The recombinant protein was used as the immunogen to immunize BALB/c mice. A hybridoma cell line 8A12 secreting monoclonal antibody(MAb) against RRSV was obtained by fusing mouse myeloma cells(Sp 2/0) with spleen cells from the immunized BALB/c mice. Western blot analysis showed that the MAb 8A12 can specifically react with RRSV CP. Using the MAb, an antigen-coated-plate enzyme-linked immunosorbent assay(ACP-ELISA), a dot enzyme-linked immunosorbent assay(dot-ELISA), and immunocapture-RT-PCR(IC-RT-PCR) assay were developed to detect RRSV. The established ACP-ELISA, dot-blot ELISA and IC-RT-PCR methods could detect RRSV in infected rice tissue crude extracts with dilutions of 1:40 960, 1:1 280 and 1:655 360(w/v, g mL-1), respectively. The ACP-ELISA and dot-blot ELISA methods could detect RRSV in infected insect vector crude extracts with dilutions of 1:12 800 and 1:1 600(an individual planthopper μL-1), respectively. The field survey revealed that Rice ragged stunt disease occurs on rice in Hainan, Yunnan, Guangxi, Sichuan, Guizhou, Fujian, Hunan, Jiangxi and Zhejiang in China.LIU Huan SONG Xi-jiao NI Yue-qun LU Li-na ZHOU Xue-ping WU Jian-xiang 2014Journal of Integrative Agriculture2014,13,9:5
20Nanosheet-structured K–Co–MoS_2 catalyst for the higher alcohol synthesis from syngas: Synthesis and activation显示文摘The nanosheets structured K–Co–MoS_2 catalyst was prepared through a one-step hydrothermal synthesis combined with the wetness impregnation. The fresh catalyst has a high dispersion of Co–Mo–S active phase and no Co_9S_8 is found. The pure H_2 activated catalyst shows a higher intrinsic activity, especially the C_(2+) OH selectivity for the higher alcohol synthesis compared to the one activated by 5% H_2/N_2 atmosphere. The reason is attributed to that the pure H_2 activation more effectively suppresses the formation of Co_9S_8 and stabilizes the Co–Mo–S active phase during the reaction due to the formation of SH species.Huan Li Wei Zhang Yinyin Wang Meiling Shui Song Sun Jun Bao Chen Gao 2019Journal of Energy Chemistry2019,28,3:5
