1Disentangling the effects of topography and space on the distributions of dominant species in a subtropical forest显示文摘Topography and space are two important factors determining plant species assemblages in forest communities.Quantification of the contribution of these two factors in determining species distribution helps us to evaluate their relative importance in determining species assemblages.This study aims to disentangle the effect of topography and space on the distributions of 14 dominant species in a subtropical mixed forest.Spearman correlation analysis and the torustranslation test were used to test the species–habitat associations.Variation partitioning was used to quantify the relative contributions of topography and space at three sampling scales and three life stages.Correlation analyses and torus-translation tests showed species abundance was mostly correlated with topographic wetness index,vertical distance from the channel network and convexity.Variation partitioning showed that pure topography,pure space and spatially structured topography explained about 2.1 %,41.2 % and 13.8 %of the variation in species distributions,respectively.For nine species,total topography fractions peaked in 20 m quadrats.For ten species,the pure space fractions peaked in 50 m quadrats.For many species,the total topography fraction andthe pure space fraction were larger for the most abundant life stages,which reflected the importance of sampling effect.However,some cases did not follow this trend suggesting that the effects of ecological processes such as habitat filtering,density dependence or dispersal limitation may exceed the sampling effects.In conclusion,we found that spatially structured topography and pure space primarily shaped the distribution of dominant tree species.Furthermore,their effects were both scale- and life stage-dependent.Qinggang Wang Yaozhan Xu Zhijun Lu Dachuan Bao Yili Guo Junmeng Lu Kuihan Zhang Haibo Liu Hongjie Meng Xiujuan Qiao Handong Huang Mingxi Jiang 2014Chinese Science Bulletin2014,59,35:16
2COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented.Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu 2021China CDC weekly2021,3,21:16

4Wearable strain sensing textile based on one-dimensional stretchable and weavable yarn sensors显示文摘Flexible, wearable, and even stretchable sensors are the key components ofsmart electronic textiles. However, most reported flexible and wearable sensorsfor wearable electronics are usually fabricated in two-dimensional (2D) planarstrip configurations, which cannot be properly integrated into textile structuresand thus greatly degrade intrinsic properties such as the softness, flexibility, andair permeability of textiles and the aesthetic feeling of clothing. In this work, a newone-dimensional weavable strain sensing yarn consisting of an elastic polyurethane(PU) core, a conductive Ag-nanopartides/graphene-microsheets composite sheath,and a silicone encapsulation layer was designed and fabricated through aneasily manipulated protocol. Arising from the reasonable structural design andappropriate material selection, the as-fabricated strain sensor not only exhibitedexcellent flexibility, stretchability, and highly repeatable electromechanicalstability (a repeatability error of 1.56%) but also possessed both high sensitivity(a gauge factor of nearly 500) and a relatively wide working range (0-50%applied strain) with good linearity (a correlation coefficient of 0.98). In addition,the facile, nearly all-solution-based fabrication protocol enabled the scalableproduction of long conductive yams. Thus, the proper yarn length and superbmechanical properties endowed the stretchable conductive yarn with goodweavability. The excellent wearability of the stretchable conductive yarn wasderived from the outermost isolating, hydrophobic, and biocompatible siliconeencapsulation layer. A wearable high-sensitivity strain sensing textile, fabricatedby directly weaving the as-prepared yarn-based sensor, showed great potentialfor application to wearable textile sensors for real-time monitoring of humanmotions from vigorous walkin~ to subtle and complex pronunciations.Xiaoting Li Haibo Hu Tao Hua Bingang Xu Shouxiang Jiang 2018Nano Research2018,11,11:13
5Study on formation of non-metallic inclusions with lower melting temperatures in extra low oxygen special steels显示文摘Investigations were made both in laboratorial and industrial scales on formation of non-metallic inclusions with relatively lower melting temperatures to improve the fatigue property of the special steels which contained extra low oxygen.It was found in laboratory studies that steel/slag reaction time largely affected non-metallic inclusions in steel.With the slag/steel reaction time increasing from 30 to 90 min,inclusions of MgO-Al2O3 spinel were gradually changed into CaO-MgO-Al2O3 system inclusions which were surrounded by lower melting temperature softer CaO-Al2O3 surface layers.By using high basicity and as much as 41 mass% Al2O3 refining slag,the ratio of the lower melting temperature CaO-MgO-Al2O3 system inclusions was remarkably increased to above 80%.In the industrial experiments,it was found that the inclusions changed in the order of 'Al2O3 →MgO-Al2O3 system→CaO-MgO-Al2O3 system' in the secondary refining,and the change from MgO-Al2O3 system to CaO-MgO-Al2O3 system took place from the outside to the inside.The diffusion of CaO and MgO inside the layer of CaO-MgO-Al2O3 was considered as the controlling step of the inclusion transfer.Through LF and RH refining,most inclusions could be transferred to lower melting temperature CaO-Al2O3 and CaO-MgO-Al2O3 system inclusions.WANG XinHua JIANG Min CHEN Bing LI HaiBo 2012Science China(Technological Sciences)2012,55,7:12
6Recent Advances on the Electrochemical Difunctionalization of Alkenes/Alkynes显示文摘Electroorganic synthesis is an emerging area of high impact research in organic chemistry, which is considered as one of the green and efficient methods and attracts growing research attention.

8Perovskite light-emitting/detecting bifunctional fibres for wearable LiFi communication显示文摘Light fidelity(LiFi),which is emerging as a compelling technology paradigm shifting the common means of highcapacity wireless communication technologies,requires wearable and full-duplex compact design because of its great significance in smart wearables as well as the‘Internet of Things’.However,the construction of the key component of wearable full-duplex LiFi,light-emitting/detecting bifunctional fibres,is still challenging because of the conflicting process between carrier separation and recombination,as well as the highly dynamic film-forming process.Here,we demonstrate light-emitting/detecting bifunctional fibres enabled by perovskite QDs with hybrid components.The hybrid perovskite inks endow fibres with super-smooth QD films.This,combined with the small exciton binding energy and high carrier mobility of perovskite QDs,enables successful integration of electroluminescence and photodetection into monofilaments.The bifunctional fibres possess the narrowest electroluminescence full width at half maximum of ~19 nm and,more importantly,the capability for simultaneously transmitting and receiving information.The successful fabrication of narrow emission full-duplex LiFi fibres paves the way for the fabrication and integration of low crosstalk interoperable smart wearables.Qingsong Shan Changting Wei Yan Jiang Jizhong Song Yousheng Zou Leimeng Xu Tao Fang Tiantian Wang Yuhui Dong Jiaxin Liu Boning Han Fengjuan Zhang Jiawei Chen Yongjin Wang Haibo Zeng 2020Light(Science & Applications)2020,9,1:7

The cream, topically used, in was prepared with Tripterygium wilfordii Hook F(TwHF), Mangxiao(Nalrii Sulfas), Chuanxiong(Rhizoma Chuanxiong), stir-frying with liquid adjuvant Ruxiang(Olibanum), and stir-frying with liquid adjuvant Moyao(Myrrh).METHODS: Patients were 1∶1 randomized to addon TwHF cream twice a day or placebo for 4 weeks.The primary endpoint was achievement rate of20% improvement in American College of Rheuma-tology criteria(ACR20) at week 4. Secondary endpoints were ACR50, 28-joint count Disease Activity Score(DAS28) improvement and safety profiles.Statistical analyses were performed using intention to treat analysis(ITT) set.RESULTS: A total of 70 active RA patients were enrolled. At week 4, the ACR20 was 34.3%(12/35) in TwHF cream group and 11.4%(4/35) in placebo group(P = 0.015). Similarly, a higher ACR50 responder proportion was seen in TwHF cream group with 17.1%(6/35) comparing to it in placebo group with 2.9%(1/35)(P = 0.046). The TwHF cream group also had more improvement than the placebo group on DAS28-ESR(1.1 vs 0.5, P = 0.001), DAS28-CRP(1.4 vs 0.7, P = 0.001), tender joint count(5.5 vs2.6, P = 0.018), swollen joint count(3.5 vs 1.6, P =0.003) and Physician's global assessment(25.8 vs13.0, P = 0.002), as well as C-reactive protein(11.2 vs 2.7, P = 0.048). Except 2 skin allergy events in TwHF cream group, no other substantive adverse events were observed.CONCLUSION: On the short term, TwHF cream is likely to be an effective and safety complimentary treatment in patients with active RA.Jiao Juan Wei Chengchung Tang Xiaopo Gong Xun Yin Haibo Jiang Quan 2019Journal of Traditional Chinese Medicine2019,39,1:6

12High electrocaloric effect in barium titanate-sodium niobate ceramics with core-shell grain assembly显示文摘Electrocaloric effect(ECE)is promising in realizing solid-state cooling as an alternative to the conventional refrigeration with environmentally harmful coolant and low efficiency.High ECE in lead-free ferroelectric ceramics is highly desirable for the EC cooling.In this work,different from the researches that tune the ECE by conventional compositional design or external stress engineering,we fabricated the(1-x)BaTiO_(3)-xNaNbO_(3)(BTO-xNN)lead-free ceramics with a core-shell grain structure arising from the inhomogeneous stoichiometry of element distribution,leading to the internal compressing stress in the grains.It is interesting that the phase transition behavior,including the phase transition temperature and the diffusion property,is regulated by the core-shell grain structure induced internal stress,which can be capitalized on for the favorable ECE.Cooperated with 0.02 NN,a high ECE,e.g.adiabatic temperature change(ΔT)of 3.6 K and isothermal entropy change(ΔS)of 4.5 J kg^(-1) K^(-1),is attained in the BTO ceramic.As the internal stress further increases with more NN,the BTO-0.06NN exhibits an extremely stable ECE with a variety rate below ±4% in a wide temperature range from 300 K to 360 K.This work provides a novel approach to explore pronounced ECE in lead-free ferroelectrics for eco-friendly refrigeration.Chao Zhang Quanpei Du Wenru Li Dong Su Meng Shen Xiaoshi Qian Bing Li Haibo Zhang Shenglin Jiang Guangzu Zhang 2020Journal of Materiomics2020,6,3:4
13Cisplatin-induced vestibular hair cell lesion-less damage at high doses显示文摘Cisplatin, a widely used anticancer drug, damages hair cells in cochlear organotypic cultures at low doses, but paradoxically causes little damage at high doses resulting in a U-shaped dose-response function. To determine if the cisplatin dose-response function for vestibular hair cells follows a similar pattern, we treated vestibular organotypic cultures with doses of cisplatin ranging from 10 to 1000 μM. Vestibular hair cell lesions progressively increased as the dose of cisplatin increased with maximum damage occurring around 50-100 μM, but the lesions progressively decreased at higher doses resulting in little hair cell loss at 1000 μM. The U-shaped doseresponse function for cisplatin-treated vestibular hair cells in culture appears to be regulated by copper transporters, Ctrl, ATP7A and ATP7B, that dose-dependently regulate the uptake, sequestration and extrusion of cisplatin.Dalian Ding Haiyan Jiang Jianhui Zhang Xianrong Xu Weidong Qi Haibo Shi Shankai Yin Richard Salvi 2018Journal of Otology2018,13,4:4
14Blast-induced rock damage control in Fangchenggang nuclear power station, China显示文摘In the process of blasting excavation, stress wave propagation and gas expansion can basically induce damage to surrounding rocks, which is detrimental to rock mass integrity and engineering safety. In this case, evaluation and control of blast-induced effects are essential to the safety of nearby buildings and integrity of bedrock in blasting field. In Fangchenggang nuclear power station of China, the drill-andblast method was employed for bedrock excavation. In order to reduce the blast-induced damage zone, the wave propagation and associated damage to rock mass should be carefully investigated. In this paper, the wave propagation regressively obtained from field monitoring data was presented based on empirical formula(e.g. Sadovsky formula). The relationship between the peak particle velocity(PPV) at a distance of 30 m away from the charge hole and charge per delay in blast design was derived. Meanwhile,the acoustic tests before and after blasting were conducted to determine the damage depth of rock mass.The charge per delay in blast design was then calibrated based on the blast-induced wave propagation regularity. The results showed that a satisfactory effect was achieved on blast-induced damage control of rock mass. This could be helpful to rock damage control in similar blasting projects.Yongqing Zeng Haibo Li Xiang Xia Bo Liu Hong Zuo Jinlin Jiang 2018Journal of Rock Mechanics and Geotechnical Engineering2018,10,5:3
15Antioxidative stress-induced damage in cochlear explants显示文摘The imbalance of reactive oxygen species and antioxidants is considered to be an important factor in the cellular injury of the inner ear. At present, great attention has been placed on oxidative stress. However,little is known about fighting oxidative stress. In the current study, we evaluated antioxidant-induced cochlear damage by applying several different additional antioxidants. To determine whether excessive antioxidants can cause damage to cochlear cells, we treated cochlear explants with 50 m M M40403, a superoxide dismutase mimetic, 50 m M coenzyme Q-10, a vitamin-like antioxidant, or 50 m M d-methionine, an essential amino acid and the important antioxidant glutathione for 48 h. Control cochlear explants without the antioxidant treatment maintained their normal structures after incubation in the standard serum-free medium for 48 h, indicating the maintenance of the inherent oxidative and antioxidant balance in these cochlear explants. In contrast, M40403 and coenzyme Q-10-treated cochlear explants displayed significant hair cell damage together with slight damage to the auditory nerve fibers.Moreover, d-methiodine-treated explants exhibited severe damage to the surface structure of hair cells and the complete loss of the spiral ganglion neurons and their peripheral fibers. These results indicate that excessive antioxidants are detrimental to cochlear cells, suggesting that inappropriate dosages of antioxidant treatments can interrupt the balance of the inherent oxidative and antioxidant capacity in the cell.Dalian Ding Jianghui Zhang Fang Liu Peng Li Weidong Qi Yazhi Xing Haibo Shi Haiyan Jiang Hong Sun Shankai Yin Richard Salvi 2020Journal of Otology2020,15,1:3
16In vivo transfection of enhanced green fluorescent protein in rat retinal ganglion cells mediated by ultrasound-induced microbubbles显示文摘BACKGROUND:Studies have demonstrated that ultrasound-mediated microbubble destruction significantly improves transfection efficiency of enhanced green fluorescent protein(EGFP) in in vitro cultured retinal ganglial cells(RGCs). OBJECTIVE:To investigate the feasibility of ultrasound-mediated microbubble destruction for EGFP transfection in rat RGCs,and to compare efficiency and cell damage with traditional transfection methods. DESIGN,TIME AND SETTING:In vivo,gene engineering experiment.The study was performed at the Central Laboratory,Institute of Ultrasonic Imaging,Chongqing Medical University from March to July 2008. MATERIALS:Eukaryotic expression vector plasmid EGFP and microbubbles were prepared by the Institute of Ultrasonic Imaging,Chongqing Medical University.The microbubbles were produced at a concentration of 8.7×10^(11)/L,with a 2-4μm diameter,and 10-hour half-life in vitro. METHODS:A total of 50 Sprague Dawley rats were randomly assigned to four groups.Normal controls(n=5) were infused with 5μL normal saline to the vitreous cavity;the naked plasmid group (n=15) was infused with 5μL EGFP plasmid to the vitreous cavity;in the plasmid with ultrasound group(n=15),the eyes were irradiated with low-energy ultrasound wave(0.5 W/cm^2) for a total of 60 seconds(irradiated for 5 seconds,at 10-second intervals) immediately following infusion of EGFP plasmids to the vitreous cavities.In the microbubble-ultrasound group(n=15),the eyes were irradiated with the same power of ultrasonic wave immediately following infusion of microbubbles containing EGFP plasmids to the vitreous cavities. MAIN OUTCOME MEASURES:After 7 days,retinal preparations and EGFP expression in RGCs were observed by fluorescence microscopy.RGC quantification in the retinal ganglion cell layer was performed.In addition,EGFP mRNA expression was semi-quantitatively determined by RT-PCR. RESULTS:The transfection efficiency of EGFP to RGCs by microbubbles with ultrasound was significantly greater than the other groups,and no obvious damage was detected in the RGCs. CONCLUSION:Under irradiation of low-frequency ultrasound waves,ultrasound-mediated microbubble destruction was effective and resulted in safe transfection of the EGFP gene to the RGCs.Hong Su Su Liu Zhigang Wang Wenyue Xie Bing Jiang Haibo Xiong 2009Neural Regeneration Research2009,4,6:3

18Self-cleaning and Oil/Water Separation of 3D Network Super-hydrophobic Bead-like Fluorinated Silica Pellets/Poly(aryl ether ketone)Composite Membrane Fabricated via a Facile One-step Electrospinning显示文摘Novel super-hydrophobic fluorinated silica pellets/poly(aryl ether ketone)composite membranes with controllable structure have been prepared through incorporating poly(aryl ether ketonc)s with(3-triluoromethyl)-phenyl side groups and fluorinated silica pellets(F-SiO2)by a facile one-step electrospinning.Under the condition of adding 50%(mass fraction)F-SiO2 in the composite membrane,the water contact angle(WCA)reached its maximum(157°±4.3°).The controllable micro/nano-structures grown on the electrospun fibers could be regulated by the F-SiO2 loading,which was illustrated by scanning clectron microscopy(SEM).Moreover,these super-hydrophobic mem-branes also demonstrated excellent durability,anti-fouling property and oil-water separation ability after 200 h of water flushing.These promising PAEK composite membranes with controllable structure have the potential values in large-scale application of filtration,oil-water separation and antifouling.CUI Zengduo WANG Yongpeng LIU Mengzhu ZHANG Haibo JIANG Zhenhua 2020Chemical Research in Chinese Universities2020,36,6:2
19Applications and prospects of functional oligosaccharides in pig nutrition:A review显示文摘Oligosaccharides are low molecular weight carbohydrates between monosaccharides and poly-saccharides,which consist of 2 to 20 monosaccharides linked by glycosidic bonds.They have the effects of promoting growth,regulating immunity,improving the structure of intestinal flora,and are anti-inflammatory and antioxidant.With the comprehensive implementation of the antibiotic prohibition policy in China,oligosaccharides as new green feed additive have been paid more attention.Oligosac-charides can be divided into the following 2 categories according to their digestive characteristics:one is easy to be absorbed by the intestine,called common oligosaccharides,such as sucrose and maltose oligosaccharide;the other is difficult to be absorbed by the intestine and has special physiological functions,called functional oligosaccharides.The common functional oligosaccharides include mannan oligosaccharides(MOS),fructo-oligosaccharides(FOS),chitosan oligosaccharides(COS),xylo-oligosaccharides(XOS)and so on.In this paper,we review the types and sources of functional oligo-saccharides,their application in pig nutrition,and the factors limiting their efficacy in recent years.This review provides the theoretical basis for further research of functional oligosaccharides,and the future application of alternative antibiotics in pig industry.Nian Liu Haibo Shen Fan Zhang Xiang Liu Qinrui Xiao Qian Jiang Bie Tan Xiaokang Ma 2023Animal Nutrition2023,,2:2
20Analysis of the Stability and Mechanical Characteristics of the Jointed Surrounding Rock and Lining Structure of a Deeply Buried Hydraulic Tunnel显示文摘On-site monitoring and numerical simulation have been combined to analyze the stability of the jointed surrounding rock and the stress inside the lining structure of a sample deeply buried hydraulic tunnel.We show that the deformation around the tunnel was mainly concentrated in the range 51.37 mm∼66.73 mm,the tunnel circumference was dominated by shear failure,and the maximum plastic zone was about 3.90 m.When the shotcrete treatment was performed immediately after the excavation,the deformation of the surrounding rock was reduced by 58.94%∼76.31%,and the extension of the plastic zone was relatively limited,thereby leading to improvements in terms of the stability of surrounding rock.When the support was provided at different time points,the stress of the surrounding rock in the shallow part of the tunnel was improved everywhere.In the tunnel section with high ground stress and joint development,when 10 cm steel fiber concrete spray layer and 40 cm C25 concrete secondary lining were used,the maximum tensile stress on the lining structure was 0.89 MPa,i.e.,it was less than the tensile strength of concrete,which indicates that the internal force of the lining can meet the overall requirements.Changchang Li Zuguo Mo Haibo Jiang Fengchun Yang 2022Fluid Dynamics & Materials Processing2022,18,1:2
