1Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT.WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin 2014Science China Earth Sciences2014,57,1:106
2Effects of dietary Bacillus amyloliquefaciens supplementation on growth performance,intestinal morphology, inflammatory response, and microbiota of intra-uterine growth retarded weanling piglets显示文摘Background: The focus of recent research has been directed toward the probiotic potential of Bacillus amyloliquefaciens(BA) on the gut health of animals. However, little is known about BA's effects on piglets with intra-uterine growth retardation(IUGR). Therefore, this study investigated the effects of BA supplementation on the growth performance,intestinal morphology, inflammatory response, and microbiota of IUGR piglets.Methods: Eighteen litters of newborn piglets were selected at birth, with one normal birth weight(NBW) and two IUGR piglets in each litter(i.e., 18 NBW and 36 IUGR piglets in total). At weaning, the NBW piglet and one of the IUGR piglets were assigned to groups fed a control diet(i.e., the NBW-CON and IUGR-CON groups). The other IUGR piglet was assigned to a group fed the control diet supplemented with 2.0 g BA per kg of diet(i.e., IUGR-BA group). The piglets were thus distributed across three groups for a four-week period.Results: IUGR reduced the growth performance of the IUGR-CON piglets compared with the NBW-CON piglets. It was also associated with decreased vil us sizes, increased apoptosis rates, reduced goblet cel numbers, and an imbalance between pro-and anti-inflammatory cytokines in the smal intestine. Supplementation with BA improved the average daily weight gain and the feed efficiency of the IUGR-BA group compared with the IUGR-CON group(P < 0.05). The IUGR-BA group exhibited increases in the ratio of jejunal vil us height to crypt depth, in ileal vil us height, and in ileal goblet cel density. They also exhibited decreases in the numbers of jejunal and ileal apoptotic cel s and ileal proliferative cel s(P < 0.05). Supplementation with BA increased interleukin 10 content, but it decreased tumor necrosis factor alpha level in the smal intestines of the IUGR-BA piglets(P < 0.05). Furthermore, compared with the IUGR-CON piglets, the IUGR-BA piglets had less Escherichia coli in their jejunal digesta, but more Lactobacil us and Bifidobacterium in their ileal digesta(P < 0.05).Conclusions: Dietary supplementation with BA improves morphology, decreases inflammatory response, and regulates microbiota in the smal intestines of IUGR piglets, which may contribute to improved growth performance during early life.Yue Li Hao Zhang Weipeng Su Zhixiong Ying Yueping Chen Lili Zhang Zhaoxin Lu Tian Wang 2018Journal of Animal Science and Biotechnology2018,9,2:16
3COVID-19: Challenges to GIS with Big Data显示文摘The outbreak of the 2019 novel coronavirus disease(COVID-19)has caused more than 100,000 people infected and thousands of deaths.Currently,the number of infections and deaths is still increasing rapidly.COVID-19 seriously threatens human health,production,life,social functioning and international relations.In the fight against COVID-19,Geographic Information Systems(GIS)and big data technologies have played an important role in many aspects,including the rapid aggregation of multi-source big data,rapid visualization of epidemic information,spatial tracking of confirmed cases,prediction of regional transmission,spatial segmentation of the epidemic risk and prevention level,balancing and management of the supply and demand of material resources,and socialemotional guidance and panic elimination,which provided solid spatial information support for decision-making,measures formulation,and effectiveness assessment of COVID-19 prevention and control.GIS has developed and matured relatively quickly and has a complete technological route for data preparation,platform construction,model construction,and map production.However,for the struggle against the widespread epidemic,the main challenge is finding strategies to adjust traditional technical methods and improve speed and accuracy of information provision for social management.At the data level,in the era of big data,data no longer come mainly from the government but are gathered from more diverse enterprises.As a result,the use of GIS faces difficulties in data acquisition and the integration of heterogeneous data,which requires governments,businesses,and academic institutions to jointly promote the formulation of relevant policies.At the technical level,spatial analysis methods for big data are in the ascendancy.Currently and for a long time in the future,the development of GIS should be strengthened to form a data-driven system for rapid knowledge acquisition,which signifies ts that GIS should be used to reinforce the social operation parameterization of models and methods,especially when providing support for social management.Chenghu Zhou Fenzhen Su Tao Pei An Zhang Yunyan Du Bin Luo Zhidong Cao Juanle Wang Wen Yuan Yunqiang Zhu Ci Song Jie Chen Jun Xu Fujia Li Ting Ma Lili Jiang Fengqin Yan Jiawei Yi Yunfeng Hu Yilan Liao Han Xiao 2020Geography and Sustainability2020,1,1:13
4Particle sizing in dense two-phase droplet systems by ultrasonic attenuation and velocity spectra显示文摘Size and size distribution of particles in particulate two-phase flow play an important role in a wide variety of industrial areas,while their measurement still remains a hard task till now.Ultrasonic wave as a mechanical vibration contains plenty of information about medium when it passes through.Thus the size distribution could be extracted from the measured ultrasonic attenuation and velocity spectra by means of well established models and data processing techniques.This paper contributes to the extraction of information of droplet size of a two-phase fat emulsion simultaneously from signals of broad-band ultrasonic attenuation and velocity spectra.According to the formulated single particle scattering model,the relationship between particle size distribution and ultrasonic spectrum is estab-lished.The sensitivities of ultrasonic spectra to the variation of particle size are illustrated.Distin-guishing features for attenuation and velocity spectra are summarized.Demonstration calculations of inversion by optimum regularization factor method are carried out to yield the typical numerical results for discussion.Based on the proposed inversion algorithm and theoretical model,a fat emulsion sam-ple with a volume fraction up to 20% is measured and analyzed.To validate the proposed ultrasonic spectrum particle sizing method,the results are compared to those obtained from optical measure-ment.SU MingXu CAI XiaoShu XUE MingHua DONG LiLi XU Feng 2009Science China(Technological Sciences)2009,52,6:11

7Photocatalytic degradation of Rhodamine B under visible light with Nd-doped titanium dioxide films显示文摘Microporous titanium dioxide films were prepared by the sol-gel methods on glass substrates, using tetrabutyl titanate as source material. In order to absorb the visible light and increase the photocatalytic activities, different concentrations of neodymium ions (Nd/Ti molar ratio was 0.5%, 0.7%, 0.9%, and 1.1% respectively) were added into the sol. X-ray diffraction (XRD), X-ray photoelectron spectros-copy (XPS), and atom force microscopy (AFM) were applied to characterize the modified films. A kind of typical textile industry pollutant (Rhodamine B) was used to evaluate the photocatalytic activities of the films under visible light. The results showed that the activities of the films were improved by doping Nd ions into the sol.WU Xiaohong SU Peibo LIU Huiling QI Lili 2009Journal of Rare Earths2009,27,5:6
8High Response Gas Sensors for Formaldehyde Based on Er-doped In_2O_3 Nanotubes显示文摘Pure and Er-doped In_2O_3 nanotubes were systematically fabricated by using a single nozzle eletrospinning method followed by calcination.The as-synthesized nanotubes were characterized by scanning electron microscopy(SEM),energy-dispersive X-ray(EDX) spectrometry and X-ray powder diffraction(XRD).Compared with pure In_2O_3 nanotubes,Er-doped In_2O_3 nanotubes exhibit improved formaldehyde sensing properties at 260 ℃.The response of Er-doped In_2O_3 nanotubes to 20 ppm formaldehyde is about 12,which is 4 times larger than that of pure In_2O_3 nanotubes.The response and recovery times of Er-doped In_2O_3 nanotubes to 20 ppm formaldehyde are about 5 and 38 s,respectively.Furthermore,the response of Er-doped In_2O_3 nanotubes to 100 ppb formaldehyde is 2.19.Xuesong Wang Jinbao Zhang Lianyuan Wang Shouchun Li Li Liu Chang Su Lili Liu 2015Journal of Materials Science & Technology2015,31,12:2
9Anti-hypertensive and endothelia protective effects of Fufang Qima capsule(复方芪麻胶囊) on primary hypertension via adiponectin/adenosine monophosphate activated protein kinase pathway显示文摘OBJECTIVE:To investigate the potential mechanism of the vascular remodeling effect and provide additional information about anti-hypertension activity of Fufang Qima capsule(复方芪麻胶囊,QM).METHODS:Spontaneous hypertensive rats(SHRs)were used to study the underlying mechanism of the anti-hypertension activity of QM.In this study,SHRs were randomly divided into 5 groups:model group,Telmisartan group(7.2 mg/kg,p.o.),and three QM groups(0.9298,1.8596,and 3.7192 g/kg,p.o.).Wistar Kyoto rats(WKY)were used as normal control group.Blood pressure(BP),aorta,perivascular adipose tissue(PVAT)histology were investigated to evaluate the effect of QM.Nitric oxide(NO)and endothelial nitric oxide synthase(eNOS)phosphorylation were measured.Adiponectin(APN)secretion,as well as APN signal pathway proteins including APN,adiponectin receptors(R1 and R2)and adenosine 5’-monophosphate-activated protein kinase(AMPK)were all analyzed.RESULTS:QM significantly reduced BP and ameliorated the vascular pathological change,i.e.intima media thicken and collagen fiber hyperplasia.Meanwhile,QM increased concentration of NO and the phosphorylation of eNOS in the aorta.The anti-hypertensive and endothelia-protective effect of QM could be attributed to activating APN/AMPK pathway by up-regulating the expression of APN in PVAT and APN Receptor 2,AMPKαand phosphorylated AMPKαin the aorta.CONCLUSION:The QM alleviation effect mechanism for primary hypertension was via modulating the APN/AMPK signal pathway.ZHAO Zhiyue SHI Zhenyu ZHANG Zhenzhen LI Yinghong ZENG Xiaohui CHEN Yuxing YAO Nan ZHOU Min SU Hui WANG Qinghai JIN LiLi 2021Journal of Traditional Chinese Medicine2021,41,6:2
10Surface modification of up-conversion luminescence material Na[Y_(0.57)Yb_(0.39)Er_(0.04)]F_4 with hydrosulfide group显示文摘A new method was reported for surface modification of an up-conversion luminescence material with hydrosulfide group. The factors that may influence the surface modification,such as reaction time,amount of catalyzer and modifier,and reaction solvent,were investigated. The optimal conditions were that the reaction time,the quantity of the basic catalyzer,the quantity of modifier and the volume of reaction solvent were 40 min,1.0,1.0,and 40 mL,respectively. The results indicated that hydrosulfide group content modified on the surface of up-conversion luminescence material reached to 0.1430 mmol/g,and this modified up-conversion lumi-nescence material could be widely used in the study of structure of protein and the property of microenvironment.Lili Cui Huili Fan Junping Xiao Xiaowei Xu Dong Su 2008Journal of University of Science and Technology Beijing2008,15,5:2
11Immobilization of heparin on decellularized kidney scaffold to construct microenvironment for antithrombosis and inducing reendothelialization显示文摘In recent years, rapid development of tissue engineering technology provides possibilities for the construction of artificial tissues or organs. In construction of engineered kidneys, researchers used native decellularized extracellular matrix(ECM) as the scaffolds to recellularization. However, thrombosis has been a great issue that hinders the progress of transplantation in vivo. In this study, heparin was immobilized to the collagen part of decellularized scaffold with collagen-binding peptide(CBP). Through the anticoagulant and endothelial cell reperfusion experiments, it can be demonstrated that the heparinized scaffolds absorbed less platelets and red blood cells which can effectively reduce the formation of thrombosis. Moreover, it is conducive to longterm adhesion of endothelial cells which is important for the formation of subsequent vascularization. Taken together, our results reveal that the whole kidney can be modified by CBP-heparin composite to reduce the thrombosis and provide the better conditions for neovascularization.Miao Wang Lili Bao Xinyu Qiu Xiaoshan Yang Siying Liu Yuting Su Lulu Wang Bo Liu Qing He Shiyu Liu Yan Jin 2018Science China(Life Sciences)2018,61,10:1
12增温和放牧对高寒草甸凋落物分解及其养分释放的影响不依赖于凋落物品质显示文摘在放牧生态系统中,增温、放牧和调落物品质共同决定着凋落物分解和养分释放。然而,在以往的研究中这些因子的效应通常被单独地研究。在本研究中,我们在青藏高原高寒草甸开展了一个昼夜非对称增温和中度放牧两因子的调落物分解试验。从每个处理中收集了调落物样品,这些调落物一部分放在它们的来源处理小区,另一部分放在其他处理小区以此来探究增温、放牧以及调落物品质对调落物分解和养分释放的影响。研究结果表明,增温而不是放牧显著增加了调落物质量的损失、单位面积全碳、全氮以及全磷含量的损失,这主要是因为增温增加了落物生物量和分解速率。然而,尽管同时增温放牧处理也加快了调落物分解速率,但由于降低了调落物生物量,所以增温放牧处理并没有显著影响单位面积的凋落物碳和养分释放量。相比木质素含量和碳氮比而言,季节性土壤平均温度能够更好地预测调落物分解速率。增温和放牧对调落物分解存在交互作用,但它们和调落物品质对调落物的影响均不存在交互作用。单位面积的总氮释放的温度敏感性要高于总磷。因此,我们的结果表明,增温对调落物分解以及养分释放的影响要显著大于调落物品质变化对其分解的影响。在高寒草甸,氮释放的增加可能会间接导致土壤磷有效性的缺乏。Bowen Li Wangwang Lv Jianping Sun Lirong Zhang Lili Jiang Yang Zhou Peipei Liu Huan Hong Qi Wang Wang A Suren Zhang Lu Xia Zongsong Wang Tsechoe Dorji Ailing Su Caiyun Luo Zhenhua Zhang Shiping Wang 2022Journal of Plant Ecology2022,15,5:1
13Synergetic Insulation and Induction Effects Selectively Optimize Multiresonancee Thermally Activated Delayed Fluorescence显示文摘Multiresonance(MR)emitters featuring narrowband emissions and theoretically 100%exciton harvesting are great potential for organic light-emitting diode(OLED)applications.However,how to functionalize MR molecules without scarifying emission color purity is still a key challenge.Herein,we report a feasible strategy for selective optimization of MR molecules,which is demonstrated by a blue MR emitter tCBNDASPO substituted with a diphenylphosphine oxide(DPPO)group.Compared to its DPPO-free parent molecule,tCBNDASPO preserves narrowband feature with full widths at half maximum(FWHM)values of 28 nm in film and 32 nm in OLEDs and achieves 40%increased photoluminescence(92%)and electroluminescence quantum efficiencies(28%).It is showed that insulation effect of P=O effectively confines the singlet excited state on MR core to keep emission color purity,and its induction effect enhances singlet radiation and triplet-to-singlet conversion.This synergism for selective optimization is based on rational linkage between MR core and functional groups.Jinkun Bian Su Chen Lili Qiu Nan Zhang Jing Zhang Chunbo Duan Chunmiao Han Hui Xu 2022Research2022,,4:1
14Is oral microbiome of children able to maintain resistance and functional stability in response to short-term interference of ingesta?显示文摘Dear Editor,A series of studies had focused on the ecological stability of human microbiome(Lozupone et al.,2012;Faith et al.,2013;Moya and Ferrer,2016).Despite the continuous perturbation and the highly personalized composition within the human microbiome(Human Microbiome Project,2012),healthy adults stably maintain their microbial communities in terms of space and time(Faith et al.,2013;Moya and Ferrer,2016;Oh et al.,2016).This stability is proved to be critical for the well-being of human body(Lozupone et al.,2012).On the contrary,major shifts in microbial community composition are often related to diseases(Lynch and Pedersen,2016).Fangqiao Wei Xiangyu Sun Yufeng Gao Haoyu Dou Yang Liu Lili Su Haofei Luo Ce Zhu Qian Zhang Peiyuan Tong Wen Ren Zhe Xun Ruochun Guo Yuanlin Guan Shenghui Li Yijun Qi Junjie Qin Feng Chen Shuguo Zheng 2021Protein & Cell2021,12,6:1
15Phenylpropanoid metabolism and pigmentation show divergent patterns between brown color and green color cottons as revealed by metabolic and gene expression analyses显示文摘Background:Naturally-colored cotton has become increasingly popular because of their natural properties of coloration,UV protection,flame retardant,antibacterial activity and mildew resistance.But poor fiber quality and limited color choices are two key issues that have restricted the cultivation of naturally-colored cotton.To identify the possible pathways participating in fiber pigmentation in naturally-colored cottons,five colored cotton accessions in three different color types(with green,brown and white fiber)were chosen for a comprehensive analysis of phenylpropanoid metabolism during fiber development.Results:The expression levels of flavonoid biosynthesis pathway genes in brown cotton fibers were significantly higher than those in white and green cotton fibers.Total flavonoids and proanthocyanidin were higher in brown cotton fibers relative to those in white and green cotton fibers,which suggested that the flavonoid biosynthesis pathway might not participate in the pigmentation of green cotton fibers.Further expression analysis indicated that the genes encoding enzymes for the synthesis of caffeic acid derivatives,lignin and lignan were activated in the developing fibers of the green cotton at 10 and 15 days post-anthesis.Conclusions:Our results strengthen the understanding of phenylpropanoid metabolism and pigmentation in green and brown cotton fibers,and may improve the breeding of naturally-colored cottons.LI Zhonghua SU Qian XU Mingqi YOU Jiaqi KHAN Anam Qadir LI Junyi ZHANG Xianlong TU Lili YOU Chunyuan 2020Journal of Cotton Research2020,3,4:1
