| 4 | Study on Age and Education Level and Their Relationship with Fall-Related Injuries in Shanghai, China显示文摘Objective To study age and educational level and their relationship with fall-related injuries in Shanghai and to analyze the relevant costs. Methods Multistage cluster sampling was used for the selection of participants and standardized questionnaires were used for the information collection in 2006. Information on cases and deaths caused by fall-related injuries were obtained from 494 hospitals as well as from the mortality registry systems from 2001 till 2010. Results Of 45 857 participates, 674 suffered from fall-related injuries with the largest proportion among all injuries. The fall-related mortality increased from 10.63 per 100 000 in 2001 to 14.11 per 100 000 in 2010. The under-five mortality rate was the highest among children aged 0-14 years. Mortality increased dramatically among those aged 55 or above for the female and aged 60 or older for the male. Individuals with an educational level under the primary school were more likely to suffer fall-related injuries, accounting for 72.66% of all deaths and 49.24% of nonfatal cases respectively. The annual burden of fall-related injuries equated to 25.90% of the share of GDP for the healthcare, social security and welfare industries in 2006. Conclusion Fall-related injuries were inversely related to victims' educational level. Children under the age of 5, women over 55 years old and men over 60 years old with an educational level lower than the primary school are the most risky groups of populations for intervention measures. | LI Yan Hong SONG Gui Xiang YU Yan ZHOU De Ding ZHANG Hong Wei | 2013 | Biomedical and Environmental Sciences2013，26，2： | 12 |

| 6 | Association between Plasma Metal Levels and Diabetes Risk: a Case-control Study in China显示文摘Objective Many metals, some of which have been classified as environmental endocrine disruptors, are used extensively in everyday consumer products and are ubiquitous in our living environment. In the present study, we aimed to explore the associations between the prevalence risk of type 2 diabetes and plasma levels of 20 trace elements as well as those of heavy metals in a Han Chinese population. Methods We conducted a case-control study to investigate the associations between plasma concentrations of 20 metals and diabetes in Jiangsu province. A total of 122 newly diagnosed cases of type 2 diabetes and 429 matched controls were recruited from community physical examinations in Suzhou City of Jiangsu Province. Plasma metal levels were measured by inductively-coupled plasma mass spectrometry. Results After adjusting for confounders, plasma vanadium, chromium, manganese, copper, zinc, arsenic, selenium, strontium, palladium, cadmium, cesium, and barium were associated with diabetes risk(P < 0.05). The adjusted OR increased with increasing concentration of vanadium, manganese, copper, zinc, and cesium. Conclusion Many metals, including manganese, copper, zinc, arsenic, selenium, and cadmium in plasma, are associated with the morbidity of diabetes. Monitoring of environmental metal levels and further studies are urgently needed. | LI Xiu Ting YU Peng Fei GAO Yan GUO Wen Hui WANG Jun LIU Xin GU Ai Hua JI Gui Xiang DONG Qiu WANG Bo Shen CAO Ying ZHU Bao Li XIAO Hang | 2017 | Biomedical and Environmental Sciences2017，30，7： | 8 |
| 7 | Protective paracrine effect of mesenchymal stem cells on cardiomyocytes显示文摘Objective:The aim of this study was to test the protective effect of mesenchymal stem cells(MSCs) on cardiomyocytes in vitro and to investigate the anti-apoptotic signaling pathway.Methods:MSCs from Sprague-Dawley(SD) rats were separated and cultured.MSC medium was collected from MSCs cultured in serum-free Dulbecco's modified eagle medium(DMEM) under hypoxia.Cultured cardiomyocytes from neonatal SD rats were exposed to hypoxia/reoxygenation(H/R) and treated with MSC medium.The apoptotic cardiomyocytes were stained with Annexin-V-fluorescein isothiocyanate(FITC),Hoechst 33342 and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling(TUNEL).The mitochondrial transmembrane potential of cardiomyocytes was assessed using a fluorescence microscope.The expression of Bcl-2,Bax,cytochrome C,apoptosis-induced factor(AIF),and caspase-3 was tested by Western blot analysis.Results:Our data demonstrated that MSC medium reduced H/R-induced cardiomyocyte apoptosis,increased the Bcl-2/Bax ratio,and reduced the release of cyto-chrome C and AIF from mitochondria into the cytosol.Conclusion:MSCs protected the cardiomyocytes from H/R-induced apoptosis through a mitochondrial pathway in a paracrine manner. | Mei-xiang XIANG Ai-na HE Jian-an WANG Chun GUI | 2009 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2009，10，8： | 7 |
| 8 | Isolation and identification of symbiotic bacteria from the skin, mouth, and rectum of wild and captive tree shrews显示文摘Endosymbionts influence many aspects of their hosts’ health conditions, including physiology, development, immunity, metabolism, etc. Tree shrews(Tupaia belangeri chinensis) have attracted increasing attention in modeling human diseases and therapeutic responses due to their close relationship with primates. To clarify the situation of symbiotic bacteria from their body surface, oral cavity, and anus, 12 wild and 12 the third generation of captive tree shrews were examined. Based on morphological and cultural characteristics, physiological and biochemical tests, as well as the 16 S rDNA full sequence analysis, 12 bacteria strains were isolated and identified from the wild tree shrews: body surface: Bacillus subtilis(detection rate 42%), Pseudomonas aeruginosa(25%), Staphlococcus aureus(33%), S. Epidermidis(75%), Micrococcus luteus(25%), Kurthia gibsonii(17%); oral cavity: Neisseria mucosa(58%), Streptococcus pneumonia(17%); anus: Enterococcus faecalis(17%), Lactococus lactis(33%), Escherichia coli(92%), Salmonella typhosa(17%); whereas, four were indentified from the third generation captive tree shrews: body surface: S. epidermidis(75%); oral cavity: N.mucosa(67%); anus: L. lactis(33%), E. coli(100%). These results indicate that S. epidermidis, N. mucosa, L. lactis and E. coli were major bacteria in tree shrews, whereas, S. aureus, M. luteus, K. gibsonii, E. faecalis and S. typhosa were species-specific flora. This study facilitates the future use of tree shrews as a standard experimental animal and improves our understanding of the relationship between endosymbionts and their hosts. | Gui LI Ren LAI Gang DUAN Long-Bao LYU Zhi-Ye ZHANG Huang LIU Xun XIANG | 2014 | Zoological Research2014，35，6： | 6 |

| 11 | Assessment of Iron Bioavailability in Ten Kinds of Chinese Wheat Flours Using an in vitro Digestion/Caco-2 cell Model显示文摘Objective To compare iron bioavailability (Fe BV) from ten selected kinds of Chinese wheat flours in order to provide scientific basis for further human trials and enable plant breeding programs to screen biofortified wheat cultivars. Methods An in vitro digestion/Caco-2 cell model was used to assess Fe BV of ten flour samples from six leading Chinese wheat cultivars and the stability of Fe BV in one cultivar was studied across three growing environments. Results Significant differences were observed in both Fe BV and Fe bioavailability per gram of food (Fe BVPG) among cultivars (P<0.01) grown at the same location with the same flour extraction rate. Zhongyou 9507 and Jingdong 8 had Fe BV 37%-54% and Fe BVPG 103%-154% higher than the reference control. In the Anyang environment, Zhongyou 9507 had a higher wheat flour-Fe level and Fe BVPG. Differences in Fe BV were detected in cultivars with different flour extraction rates. Conclusion Zhongyou 9507 and Jingdong 8 were identified as the most promising cultivars for further evaluation of efficacy by using human subjects. The growing environments had no effect on Fe BV, but did have a significant effect on Fe BVPG. Fe bioavailabilities in low-extraction (40%) flours were higher than those in high-extraction (78%) flours. | LEI Ji ZHANG Yong CHEN Xiang Gui ZHANG Ming Qiu BAI Lin HUANG Cheng Yu Ortiz Monasterio IVAN | 2012 | Biomedical and Environmental Sciences2012，25，5： | 5 |

| 14 | Immunological Evaluation of a Novel Mycobacterium tuberculosis Antigen Rv0674显示文摘Objective This study aimed to characterize the diagnostic and vaccine potential of a novel Mycobacterium tuberculosisantigen Rv0674. Methods To evaluate thediagnostic potential and antigenicity of Rv0674, IgG was evaluated using ELISA and interferon (IFN)-γ was done by using ELISpot assay among TB patients and healthy donors. For immunogenicity evaluation, BALB/c mice were immunized with Rv0674. Cytokine production was determined by cytokine release assay using an ELISA kit, and the antibodies were tested using ELISA. Results The results of serum Elisa tests showed that Rv0674 specific immunoglobulin G (IgG) response was higher in TB patients than negative controls. And Rv0674 had good performance in serological test with sensitivity and specificity of 77.1% and 81.1%, respectively. While it shows poor sensitivity and specificity of 26.23% and 79.69% for IFN-γ tests. In BALB/c mice, Rv0674 adjuvant by DDA/PolyI:C could also induce a high level of IFN-γ, interleukin-2 and interleukin-6 as well as a high IgG titer in both high-and low-dose groups indicating that Rv0674 is essential in humoral and cellular immunity. Moreover, the cytokine profile and IgG isotypecharacterized Rv0674 as a Th1/Th2-mixed-type protective immunity with the predominance of Th1 cytokines. Conclusion Rv0674 may be a good potential candidate for the development of TB serological diagnosis and a new TB vaccine. | XIAO Tong Yang LIU Hai Can LI Xiao Qin HUANG Ming Xiang LI Gui Lian LI Na YAN Yu Han LUO Qiao WANG Xue Zhi LI Ma Chao WAN Kang Lin | 2019 | Biomedical and Environmental Sciences2019，32，6： | 3 |
| 15 | In vivo degradation and endothelialization of an iron bioresorbable scaffold显示文摘Detection of in vivo biodegradation is critical for development of next-generation medical devices such as bioresorbable stents or scaffolds(BRSs).In particular,it is urgent to establish a nondestructive approach to examine in vivo degradation of a new-generation coronary stent for interventional treatment based on mammal experiments;otherwise it is not available to semi-quantitatively monitor biodegradation in any clinical trial.Herein,we put forward a semi-quantitative approach to measure degradation of a sirolimus-eluting iron bioresorbable scaffold(IBS)based on optical coherence tomography(OCT)images;this approach was confirmed to be consistent with the present weight-loss measurements,which is,however,a destructive approach.The IBS was fabricated by a metal-polymer composite technique with a polylactide coating on an iron stent.The efficacy as a coronary stent of this new bioresorbable scaffold was compared with that of a permanent metal stent with the name of trade mark Xience,which has been widely used in clinic.The endothelial coverage on IBS was found to be greater than on Xience after implantation in a rabbit model;and our well-designed ultrathin stent exhibited less individual variation.We further examined degradation of the IBSs in both minipig coronary artery and rabbit abdominal aorta models.The present result indicated much faster iron degradation of IBS in the rabbit model than in the porcine model.The semi-quantitative approach to detect biodegradation of IBS and the finding of the species difference might be stimulating for fundamental investigation of biodegradable implants and clinical translation of the next-generation coronary stents. | Wenjiao Lin Hongjie Zhang Wanqian Zhang Haiping Qi Gui Zhang Jie Qian Xin Li Li Qin Haifeng Li Xiang Wang Hong Qiu Xiaoli Shi Wei Zheng Deyuan Zhang Runlin Gao Jiandong Ding | 2021 | Bioactive Materials2021，6，4： | 3 |
| 16 | Advances and perspectives in the application of CRISPR/Cas9 in insects显示文摘Insects compose more than half of all living organisms on earth, playing essential roles in global ecosystems and forming complex relationships with humans. Insect research has significant biological and practical importance. However, the application of genetic manipulation technology has long been restricted to several model insects only, such as gene knockout in Drosophila, which has severely restrained the development of insect biology research. Recently, with the increase in the release of insect genome data and the introduction of the CRISPR/Cas9 system for efficient genetic modification, it has been possible to conduct meaningful functional studies in a broad array of insect species. Here, we summarize the advances in CRISPR/Cas9 in different insect species, discuss methods for its promotion, and consider its application in future insect studies. This review provides detailed information about the application of the CRISPR/Cas9 system in insect research and presents possible ways to improve its use in functional studies and insect pest control. | Lei CHEN Gui WANG Ya-Nan ZHU Hui XIANG Wen WANG | 2016 | Zoological Research2016，37，4： | 3 |
| 17 | Catalytic performance and reaction mechanisms of NO removal with NH_(3) at low and medium temperatures on Mn-W-Sb modified siderite catalysts显示文摘Iron-based catalysts have been explored for selective catalytic reduction(SCR)of NO due to environmentally benign characters and good SCR activity.Mn-W-Sb modified siderite catalysts were prepared by impregnation method based on siderite ore,and SCR perfor-mance of the catalysts was investigated.The catalysts were analyzed by X-ray diffrac-tion,H_(2)-temperature-programmed reduction,Brunauer-Emmett-Teller,Thermogravimetry-derivative thermogravimetry and in-situ diffused reflectance infrared Fourier transform spectroscopy(DRIFTS).The modified siderite catalysts calcined at 450℃ mainly consist of Fe_(2)O_(3),and added Mn,W and Sb species are amorphous.3Mn-5W-1.5Sb-siderite catalyst has a wide temperature window of 180-360℃ and good N_(2) selectivity at low temperatures.In-situ DRIFTS results show NH_(4)^(+),coordinated NH_(3),NH_(2),NO_(3)^(-)species(bidentate),NO_(2)-species(nitro,nitro-nitrito,monodentate),and adsorbed NO_(2) can be discovered on the sur-face of Mn-W-Sb modified siderite catalysts,and doping of Mn will enhance adsorbed NO_(2) formation by synergistic catalysis with Fe^(3+).In addition,the addition of Sb can inhibit sulfates formation on the surface of the catalyst in the presence of SO_(2) and H_(2)O.Time-dependent in-situ DRIFTS studies also indicate that both of Lewis and Br?nsted acid sites play a role in SCR of NO by ammonia at low temperatures.The mechanism of NO removal on the 3Mn-5W-1.5Sb-siderite catalyst can be discovered as a combination of Eley-Rideal and Langmuir-Hinshelwood mechanisms with three reaction pathways.The mechanism of NO,oxidized by synergistic catalysis of Fe^(3+)and Mn^(4+/3+)to form NO_(2) among three pathways,reveals the reason of high NO_(x) conversion of the catalyst at medium and low temperatures. | Guihuan Yao Yuliang Wei Keting Gui Xiang Ling | 2022 | Journal of Environmental Sciences2022，34，5： | 3 |
| 18 | Comparative study of HFACS and the 24Model accident causation models显示文摘A comparative study is conducted to compare the theory and application effect of two accident causation models, the human factors analysis and classification system(HFACS) and the accident causation ‘‘2-4'' model(24 Model), as well as to provide a reference for safety researchers and accident investigators to select an appropriate accident analysis method. The two models are compared in terms of their theoretical foundations, cause classifications, accident analysis processes, application ranges, and accident prevention strategies. A coal and gas outburst accident is then analyzed using both models, and the application results are compared. This study shows that both the 24 Model and HFACS have strong theoretical foundations, and they can each be applied in various domains. In addition, the cause classification in HFACS is more practical, and its accident analysis process is more convenient. On the other hand, the 24 Model includes external factors, which makes the cause analysis more systematic and comprehensive. Moreover, the 24 Model puts forward more corresponding measures to prevent accidents. | Gui Fu Jia-Lin Cao Lin Zhou Yuan-Chi Xiang | 2017 | Petroleum Science2017，14，3： | 3 |
| 19 | Markov Chain-based Degree Distributions of Evolving Networks显示文摘In this paper, we study a class of stochastic processes, called evolving network Markov chains, in evolving networks. Our approach is to transform the degree distribution problem of an evolving network to a corresponding problem of evolving network Markov chains. We investigate the evolving network Markov chains, thereby obtaining some exact formulas as well as a precise criterion for determining whether the steady degree distribution of the evolving network is a power-law or not. With this new method, we finally obtain a rigorous, exact and unified solution of the steady degree distribution of the evolving network. | Xiang Xing KONG Zhen Ting HOU Ding Hua SHI Quan Rong CHEN Qing Gui ZHAO | 2012 | Acta Mathematica Sinica,English Series2012，28，10： | 2 |
| 20 | Ambient White-Light Afterglow Emission Based on Triplet-to-Singlet Förster Resonance Energy Transfer显示文摘Compared with fluorescent materials,metal-free organic environmental afterglow materials,with larger Stokes shifts,longer lifetimes,higher S/N ratios,and sensitivities,present potential in new applications.However,achieving air stability and long lifetime organic afterglow systems with tunable emission color still remains a challenge.Herein,we have designed and synthesized luminescent copolymers exhibiting afterglow emission with tunability including white-light afterglow with considerable quantum yield[Commission Internationale de l’Eclairage(CIE)coordinates(0.32,0.33),ΦP=11%]in the amorphous state through the rarely reported triplet-to-singlet Förster resonance energy transfer(TS-FET).Also,they can emit different colors under UV light,including white-light[CIE coordinates(0.31,0.33),ΦPl=27%].This strategy was achieved by copolymerizing two simple-structured single-benzene-based compounds with acrylamide(AM)in different ratios.In addition,these materials can also be employed as a safety ink for paper paving the way for long lifetime luminescent material applications. | Huiqiang Gui Zizhao Huang Zhiyi Yuan Xiang Ma | 2022 | CCS Chemistry2022，4，1： | 2 |
