1Ten cities cross-sectional questionnaire survey of children asthma and other allergies in China显示文摘Asthma,rhinitis and eczema(allergic or non-allergic)have increased throughout the world during the last decades,especially among children.Changes in the indoor environment are suspected to be important causes.China has experienced a dramatic change in indoor environmental exposures during the past two decades.However,such changes and their associations with children’s asthma and other health aspects have not been thoroughly studied.China,Children,Homes,Health(CCHH),Phase I,was a cross-sectional questionnaire survey of 48219 children 1–8 years old in 10 Chinese cities during 2010–2012.The questionnaire includes the International Study of Asthma and Allergies in Childhood(ISAAC)core health questions and additional questions regarding housing,life habits and outdoor environment.In health analyses,children aged 3–6 years old were included.The prevalences of doctor diagnosed asthma varied from 1.7%to 9.8%(mean 6.8%),a large increase from 0.91%in 1999 and 1.50%in2000.The prevalence of wheeze,rhinitis and atopic eczema(last 12 months)varied from 13.9%to 23.7%,24.0%to 50.8%and4.8%to 15.8%,respectively.Taiyuan had the lowest prevalences of all illnesses and Shanghai the highest,except for wheezewhere the highest value was for Urumqi.We found(1)no obvious association between disease prevalences and ambient PM10concentrations and(2)higher prevalences of disease in humid climates with hot summers and cold winters,but with no centrally heated buildings.Associations between the diseases and economic status as indexed by Gross Domestic Product(GDP)requires further study.ZHANG YinPing LI BaiZhan HUANG Chen YANG Xu QIAN Hua DENG QiHong ZHAO ZhuoHui LI AnGui ZHAO JiaNing ZHANG Xin QU Fang HU Yu YANG Qin WANG Juan ZHANG Ming WANG Fang ZHENG XiaoHong LU Chan LIU ZhiJian SUN YueXia MO JinHan ZHAO YiLi LIU Wei WANG TingTing NORBCK Dan BORNEHAG Carl-Gustaf SUNDELL Jan 2013Chinese Science Bulletin2013,58,34:22
2Indoor decorating and refurbishing materials and furniture volatile organic compounds emission labeling systems:A review显示文摘The volatile organic compounds (VOC) emitted from indoor decorating and refurbishing materials and furniture is recognized as one of the main causes of bad indoor air quality,which has resulted in serious economic losses.In European countries and the U.S.,labeling systems for indoor decorating and refurbishing materials and furniture were established to address this issue with good effect.This paper is a review of these existing labeling systems.The basic principle of the labeling systems is introduced.The technical,policy and operational parts of the labeling systems are then discussed.The research concentrates on target pollutants,their threshold values and the testing methods employed.Some problems were uncovered in these labeling systems:too many VOCs were targeted;the method to determine the threshold values was not very rigorous;the testing time was too long (7-28 d).Some China's special features in developing such system are stated.Therefore,as the world's largest national producer and consumer of wood based panels and furniture,China should learn from foreign experience of establishing labeling systems as much as it can.However China should not simply copy the foreign approaches but develop its own scientific labeling system for indoor decorating and refurbishing materials and furniture.LIU WeiWei ZHANG YinPing YAO Yuan LI JingGuang 2012Chinese Science Bulletin2012,57,20:7

5Comprehensive strategy of conduit guidance combined with VEGF producing Schwann cells accelerates peripheral nerve repair显示文摘Peripheral nerve regeneration requires stepwise and well-organized establishment of microenvironment.Since local delivery of VEGF-A in peripheral nerve repair is expected to promote angiogenesis in the microenvironment and Schwann cells(SCs)play critical role in nerve repair,combination of VEGF and Schwann cells may lead to efficient peripheral nerve regeneration.VEGF-A overexpressing Schwann cells were established and loaded into the inner wall of hydroxyethyl cellulose/soy protein isolate/polyaniline sponge(HSPS)conduits.When HSPS is mechanically distorted,it still has high durability of strain strength,thus,can accommodate unexpected strain of nerve tissues in motion.A 10 mm nerve defect rat model was used to test the repair performance of the HSPS-SC(VEGF)conduits,meanwhile the HSPS,HSPS-SC,HSPS-VEGF conduits and autografts were worked as controls.The immunofluorescent co-staining of GFP/VEGF-A,Ki67 and MBP showed that the VEGF-A overexpressing Schwann cells could promote the proliferation,migration and differentiation of Schwann cells as the VEGF-A was secreted from the VEGF-A overexpressing Schwann cells.The nerve repair performance of the multifunctional and flexible conduits was examined though rat behavioristics,electrophysiology,nerve innervation to gastrocnemius muscle(GM),toluidine blue(TB)staining,transmission electron microscopy(TEM)and NF200/S100 double staining in the regenerated nerve.The results displayed that the effects on the repair of peripheral nerves in HSPS-SC(VEGF)group was the best among the conduits groups and closed to autografts.HSPS-SC(VEGF)group exhibited notably increased CD31+endothelial cells and activation of VEGFR2/ERK signaling pathway in the regenerated nerve tissues,which probably contributed to the improved nerve regeneration.Altogether,the comprehensive strategy including VEGF overexpressing Schwann cells-mediated and HSPS conduit-guided peripheral nerve repair provides a new avenue for nerve tissue engineering.Ping Wu Zan Tong Lihua Luo Yanan Zhao Feixiang Chen Yinping Li Céline Huselstein Qifa Ye Qingsong Ye Yun Chen 2021Bioactive Materials2021,6,10:4
6Comparison of soil physico-chemical properties under different land-use and cover types in northeastern China's Horqin Sandy Land显示文摘The Horqin Sandy Land of northeastern China was originally a grassland with plenty of water and lush vegetation dominated by palatable grass species along with sparsely scattered woody species. However, it has experienced severe desertification in recent decades due to its fragile ecology together with inappropriate human activities. Currently, the landscape of the Horqin Sandy Land is dominated by irrigated croplands and sand dunes with different degrees of vegetation cover, as the region has become the most important part of the semiarid agro-pastoral ecotone of northern China. In this study, we compared soil physical and chemical properties under different land-use and cover types(irrigated cropland, rainfed cropland, sandy grassland, fixed dunes, and mobile dunes). We found that soil particle size distribution; organic C, total N, and total mineral element, microelement, and available microelement and nutrient contents; p H; CEC; and bulk density differed significantly among the land-use and cover types. In general, soil quality was highest in the cropland, intermediate in the sandy grassland, and lowest in the dunes. The most important soil quality attribute, soil organic carbon(SOC) storage, decreased in the following order: irrigated cropland(5,699 g/m^2) > sandy grassland(3,390 g/m^2) > rainfed cropland(2,411 g/m^2) > fixed dunes(821 g/m^2) > mobile dunes(463 g/m^2). SOC was significantly positively correlated with a large proportion of the other soil physico-chemical parameters. Our results suggest that the key issue in restoration of the degraded soils will be to increase SOC storage, which would also create a high potential for sequestering soil C in desertified areas of the Horqin Sandy Land.YuQiang Li JianPeng Zhang XueYong Zhao TongHui Zhang YuLin Li XinPing Liu YinPing Chen 2016Research in Cold and Arid Regions2016,8,6:4
7Carbon sequestration in the total and light fraction soil organic matter along a chronosequence in grazing exclosures in a semiarid degraded sandy site in China显示文摘Horqin Sandy Land is a fragile,seriously desertified region located in Inner Mongolia of China.Overgrazing is one of the primary drivers of desertification in this region.We investigated whether the establishment of grazing exclosures in areas with active sand dunes enhances soil carbon(C) sequestration and benefits soil recovery.The results showed that soil organic C storage was 1.4,1.9,and 3.5 times,and light fraction C storage was 2.3,3.2,and 4.4 times in the 100-cm topsoil after 7,12,and 25 years of grazing exclusion,respectively,compared to the case in active sand dunes.The light fraction of soil played an important role in soil C sequestration,although it might not change rapidly to provide an early indication of how soil C is increasing in response to grazing exclusion.The results indicated that soils could potentially sequester up to 13.8 Mt C in 25 years if active sand dunes in the study area were to be protected by exclosures.This corresponds to 12.8% of the estimated carbon loss(107.53 Mt) that has been associated with desertification over the past century in the Horqin Sandy Land.Our results suggested that exclosures have the capacity to increase soil C sequestration;however,decades will be required for soil C to recover to historical grassland levels observed prior to desertification.YinPing CHEN YuQiang LI Tala AWADA JuanJuan HAN YongQing LUO 2012Journal of Arid Land2012,4,4:3
8Conductive photo-thermal responsive bifunctional hydrogel system with self-actuating and self-monitoring abilities显示文摘Despite enormous efforts in actuators,most researches are only limited to various actuation behaviors and demonstrations of soft materials.It has not yet been reported to capture and monitor its movement status in an invisible environment.Therefore,it is of great significance to develop a self-sensing and self-actuating dual-function hydrogel actuator system to realize real-time monitoring.Here,we report a bifunctional hydrogel system with self-actuating and self-monitoring abilities,which combines the functions of photothermal actuation and electrical resistance sensing into a single material.The bilayer tough conductive hydrogel synthesized by unconventional complementary concentration recombination and cryogenic freezing technique presents a dense conductive network and high-porosity structure,achieving high toughness at 190.3 kPa of tensile strength,high stretchability(164.3%strain),and the toughness dramatically(1,471.4 kJ·m^(−3)).The working mechanism of the monitoring and self-sensing system is accomplished through the integrated monitoring device of surface temperature–bending angle–electron current,to solve the problem of not apperceiving actuator motion state when encountering obstacles in an invisible environment.We demonstrated for the first time a photothermal actuator’s motion of a football player and goalkeeper to finish the penalty and a soft actuator hand,which can achieve the action of sticking to grab and release under photo-thermal actuation.When connected to the control closed circuit,the actuator realized closed-loop monitoring and sensing feedback.The development of bifunctional hydrogel systems may bring new opportunities and ideas in the fields of material science,circuit technology,sensors,and mechanical engineering.Neng Chen Yang Zhou Yinping Liu Yuanyuan Mi Sisi Zhao Wang Yang Sai Che Hongchen liu FengJiang Chen Chong Xu Guang Ma Xue Peng Yongfeng Li 2022Nano Research2022,15,8:3
9Towards a better recording of microtubule cytoskeletal spatial organization and dynamics in plant cells显示文摘Numerous fluorescent marker lines are currently available to visualize microtubule(MT)architecture and dynamics in living plant cells, such as markers expressing p35S::GFP-MBD or p35S::GFP-TUB6.However, these MT marker lines display obvious defects that affect plant growth or produce unstable fluorescent signals. Here, a series of new marker lines were developed, including the pTUB6::VisGreen-TUB6-expressing line in which TUB6 is under the control of its endogenous regulatory elements and e GFP is replaced with VisGreen, a brighter fluorescent protein. Moreover, two different markers were combined into one expression vector and developed two dual-marker lines.These marker lines produce bright, stable fluorescent signals in various tissues, and greatly shorten the screening process for generating dual-marker lines.These new marker lines provide a novel resource for MT research.Weiwei Liu Chaofeng Wang Guangda Wang Yinping Ma Juan Tian Yanjun Yu Li Dong Zhaosheng Kong 2019Journal of Integrative Plant Biology2019,61,4:3

15Spatial flow influence factor: A novel concept for indoor air pollutant control显示文摘This paper puts forward a novel concept, the spatial flow influence factor (SFIF), which provides a new insight into the airflow structure. This concept is very helpful in the control of indoor air pollutants since: (1) for a given indoor airflow and given sources of volatile organic compounds (VOCs), the optimal arrangement of the VOC sources can easily be obtained; (2) for given positions of VOC sources and occupied regions (or target regions), the optimal indoor airflow pattern or organization can be determined; (3) the SFIF for an indoor space can also be regarded as the indoor air safety index of that space. To illustrate this concept, we present several examples of applying a SFIF to indoor air VOC control.ZHANG Yinping LI Xiaofeng WANG Xinke DENG Wei QIAN Ke 2006Science China(Technological Sciences)2006,49,1:1
