| 1 | Does flagship species tourism benefit conservation? A case study of the golden snub-nosed monkey in Shennongjia National Nature Reserve显示文摘Tourism has been widely used as a conservation strategy that directly compensates local people or management authorities, thereby contributing to development and creating incentives to preserve the landscape. Reserves or parks that are inhabited by flagship species may be able to generate more revenue through tourism than those without such species because flagship species have great potential for raising funds and creating publicity for conservation goals. In this paper, we examine flagship species tourism focused on observing the golden snub-nosed monkey (Rhinopithecus roxellana) in Shennongjia National Nature Reserve (SNNR). After the program was launched in 2006, both the number of tourists and amount of revenue received by SNNR increased as the general trends of tourism revenue in the country also increased. As a result, SNNR significantly increased rein- vestment in tourism and conservation infrastructure. Furthermore, after senior politicians visited the golden snub-nosed monkey, they abruptly changed their attitudes toward biological conservation, as indicated by an increase in both regular and additional funding for the species conservation. We conclude that flagship species tourism may not only generate revenue for conservation and management but also can improve officials' attitudes toward preserving biodiversity. However, it is important to ensure the continued safety and sustainability of such programs, from both the human and animal perspective, and we suggest stricter measures are introduced to reduce the risk of aerosol disease transmission from tourists to the monkeys. | XIANG ZuoFu YU Yang YANG Mei YANG JingYuan NIAO MingYao LIMing | 2011 | Chinese Science Bulletin2011，56，24： | 16 |
| 2 | Myocardial infarction secondary prevention study (MISPS)显示文摘Background Traditional Chinese medicine (TCM), especially herbal medicine, has been widely used in China and now is also being increasingly used in other countries for the treatment of cardiovascular diseases. Although many studies have demonstrated that certain Chinese herbal products are effective and safe for the treatment of cardiovascular diseases, most of these lack sufficient quality. Therefore, large randomized clinical trials and further scientific research to determine its safety, effectiveness are necessary.QiShen YiQi Dripping Pills (QSYQDP) is a herbal preparation clinically used in the treatment and prevention of coronary artery disease. Preliminary observations have shown its safety and effectiveness. Methods/Design This randomized, controlled trial will recruit 3600 patients with a history of myocardial infarction. Patients will be randomized into two groups by a Centr-Randomized System. One group receives QSYQDP, the other group receive aspirin. This trial protocol will describe eligibility criteria, detailed information on the treatment definition, blinding, endpoints, statistical methods, sample size determination, data management, legal aspects, and the current status of the trial. Discussion This trial is one of the first randomized, controlled clinical trial to evaluate the efficacy and safety of traditional Chinese herbal medicine in the treatment and secondary prevention of coronary artery disease. The results of this study should help to define the role of TCM in modern medical care, as well as to provide the management strategy for CAD patients in China and other countries. | Hongcai SHANG Guohua DAI Junhua HANG Yaozu XIANG Yang WANG Junping ZHANG Wuxun DU Jingyuan MAO Chen YAO Weiliang WENG Tiancai WEN Boli ZHANG | 2006 | Journal of Geriatric Cardiology2006，3，2： | 14 |

| 4 | BMP-IHH-mediated interplay between mesenchymal stem cells and osteoclasts supports calvarial bone homeostasis and repair显示文摘Calvarial bones are connected by fibrous sutures. These sutures provide a niche environment that includes mesenchymal stem cells(MSCs), osteoblasts, and osteoclasts, which help maintain calvarial bone homeostasis and repair. Abnormal function of osteogenic cells or diminished MSCs within the cranial suture can lead to skull defects, such as craniosynostosis. Despite the important function of each of these cell types within the cranial suture, we have limited knowledge about the role that crosstalk between them may play in regulating calvarial bone homeostasis and injury repair. Here we show that suture MSCs give rise to osteoprogenitors that show active bone morphogenetic protein(BMP) signalling and depend on BMP-mediated Indian hedgehog(IHH) signalling to balance osteogenesis and osteoclastogenesis activity. IHH signalling and receptor activator of nuclear factor kappa-Β ligand(RANKL) may function synergistically to promote the differentiation and resorption activity of osteoclasts. Loss of Bmpr1a in MSCs leads to downregulation of hedgehog(Hh) signalling and diminished cranial sutures. Significantly, activation of Hh signalling partially restores suture morphology in Bmpr1a mutant mice, suggesting the functional importance of BMP-mediated Hh signalling in regulating suture tissue homeostasis. Furthermore, there is an increased number of CD200+ cells in Bmpr1a mutant mice, which may also contribute to the inhibited osteoclast activity in the sutures of mutant mice. Finally, suture MSCs require BMPmediated Hh signalling during the repair of calvarial bone defects after injury. Collectively, our studies reveal the molecular and cellular mechanisms governing cell–cell interactions within the cranial suture that regulate calvarial bone homeostasis and repair. | Yuxing Guo Yuan Yuan Ling Wu Thach-Vu Ho Junjun Jing Hideki Sugii Jingyuan Li Xia Han Jifan Feng Chuanbin Guo Yang Chai | 2018 | Bone Research2018，6，4： | 12 |
| 5 | Multi-drug Resistance and Characteristic of Integrons in Shigella spp.Isolated from China显示文摘Objective To investigate the characteristic of integrons and the relationship between integrons and antimicrobial resistance in Shigella spp. Methods Ninety Shigella strains (83 S. flexneri and 7 S. sonnei) were isolated from the stools of patients in China. Susceptibility to 8 antimicrobials was tested for all isolated strains. PCR, RFLP and sequencing analysis of integrons were applied to all of them. Results High prevalence of multi‐drug resistance (95.6%) was identified. Of the isolates 79 (87.8%) carried integrase genes of class 1 integron (3.3%), class 2 integron (10.0%) or both (74.4%). No intI3 was detected in the tested isolates. The prevalence of intI2 was significantly higher in isolates with multi‐drug resistance to at least 3 antibiotics than that in isolates with resistance to 2 and less antibiotics (P<0.05). Gene cassettes dfrA17‐aadA5, dfrA12‐orfF‐aadA2 of class 1 integron and dfrA1‐sat1‐aadA1 of class 2 integron were identified. Conclusion The class 2 integron may play a role in the emergence of multi‐drug resistance in Shigella spp. | ZHU JingYuan DUAN GuangCai YANG HaiYan FAN QingTang XI YuanLin | 2011 | Biomedical and Environmental Sciences2011，24，1： | 11 |

| 7 | Modelling and simulation of two-bed PSA process for separating H2 from methane steam reforming显示文摘Methane steam reforming is the main hydrogen production method in the industry. The product of methane steam reforming contains H2, CH4, CO and CO2 and is then purified by pressure swing adsorption(PSA) technology. In this study, a layered two-bed PSA process was designed theoretically to purify H2 from methane steam reforming off gas. The effects of adsorption pressure, adsorption time and purgeto-feed ratio(P/F ratio) on process performance were investigated to design a PSA process with more than99.95% purity and 80% recovery. Since the feed composition of the PSA process changes with the upstream process, the effect of the feed composition on the process performance was discussed as well.The result showed that the increase of CH4 concentration, which was the weakest adsorbate, would have a negative impact on product purity. | Huiru Li Zuwei Liao Jingyuan Sun Binbo Jiang Jingdai Wang Yongrong Yang | 2019 | Chinese Journal of Chemical Engineering2019，27，8： | 9 |
| 8 | An Epidemic of Hepatitis A--Liaoning Province,2020显示文摘What is already known about this topic?Hepatitis A(HA)is caused by acute hepatitis A virus(HAV)infection and was once very common in China.Following the 2008 introduction of the HA vaccine into the national Expanded Program on Immunization(EPI),the incidence of reported HA in China decreased markedly.However,HA epidemics still occur in Liaoning Province every 3–5 years,although with far fewer cases than in the pre-HA-vaccination era.What is added by this report?Between January 1,2020 and March 18,2020,the number of reported cases of HA in Dalian and Dandong cities of Liaoning Province increased significantly compared with the same period in previous years.All cases were sporadic,and cases were seen in nearly every township.The increase in HA occurred one month after local fresh seafood became available with most cases being among adults.A casecontrol study showed that consuming raw or undercooked seafood,clams,snapping shrimp,and oysters were significantly associated with the increase in HA.What are the implications for public health practices?Strengthening health education for residents to avoid consumption of raw seafood and encouraging HAV vaccination of adults aged 20 to 54 years are important to prevent periodic HAV endemic outbreaks.Further multisectoral cooperation must be emphasized on HA surveillance in areas with a high prevalence of HA. | Jing Sun Yuanqiu Li Xing Fang Yan Wang Yinan Han Yang Liu Jingyuan Cao Wenting Zhou Hui Zheng Wenqing Yao | 2020 | China CDC weekly2020，2，30： | 7 |
| 9 | Noninvasive genetic assessment of the population trend and sex ratio of the Shennongjia population of Sichuan snub-nosed monkeys(Rhinopithecus roxellana)显示文摘Effective population management relies on assessments of population size and sex ratio.However,these estimates are difficult to obtain for elusive and rare species.Recently,noninvasive genetic census methods have been developed as an alternative to tradi-tional capture-mark-recapture methods.In this study,we estimated the size of the Sichuan snub-nosed monkey(Rhinopithecus roxellana) population in the Shennongjia Nature Reserve(SNR) using a noninvasive sampling method based on 16 microsatellite loci.We also used a PCR-based genetic method to sex the sampled individuals and infer the population sex ratio.The population size of R.roxellana in the SNR was estimated to be 1044 individuals(95% CITIRM:613-1409) .The estimated population sex ratio is more female-biased than expected,which we attribute to the sampling biased towards one male units and limited sampling of bachelor male units.Moreover,there is no suggestion that the heavy traffic road through the reserve might block movement of monkeys.The results of this study indicate genetic assessments based on a noninvasive sampling method can provide useful in-formation regarding populations of elusive primates. | CHANG ZongFei LIU ZhiJin YANG JingYuan LIMing VIGILANT Linda | 2012 | Chinese Science Bulletin2012，57，10： | 7 |
| 10 | Construction of a small-caliber tissue-engineered blood vessel using icariin-loaded β-cyclodextrin sulfate for in situ anticoagulation and endothelialization显示文摘The rapid endothelialization of tissue-engineered blood vessels(TEBVs) can effectively prevent thrombosis and inhibit intimal hyperplasia. The traditional Chinese medicine ingredient icariin is highly promising for the treatment of cardiovascular diseases.β-cyclodextrin sulfate is a type of hollow molecule that has good biocompatibility and anticoagulation properties and exhibits a sustained release of icariin. We studied whether icariin-loaded β-cyclodextrin sulfate can promote the endothelialization of TEBVs. The experimental results showed that icariin could significantly promote the proliferation and migration of endothelial progenitor cells; at the same time, icariin could promote the migration of rat vascular endothelial cells(RAVECs). Subsequently,we used an electrostatic force to modify the surface of the TEBVs with icariin-loaded β-cyclodextrin sulfate, and these vessels were implanted into the rat common carotid artery. After 3 months, micro-CT results showed that the TEBVs modified using icariin-loaded β-cyclodextrin sulfate had a greater patency rate. Scanning electron microscopy(SEM) and CD31 immunofluorescence results showed a better degree of endothelialization. Taken together, icariin-loaded β-cyclodextrin sulfate can achieve anticoagulation and rapid endothelialization of TEBVs to ensure their long-term patency. | Jingyuan Yang Keyu Wei Yeqin Wang Yanzhao Li Ning Ding Da Huo Tianran Wang Guanyuan Yang Mingcan Yang Tan Ju Wen Zeng Chuhong Zhu | 2018 | Science China(Life Sciences)2018，61，10： | 5 |
| 11 | Application of Spatial and Temporal Entropy Based on Multivariate Data for Measuring the Degree of Urban Function Mix显示文摘Quantifying the degree of urban function mix has great signifi cance to both urban planning practices and studies. This paper, fi rst of all, based on the data of points of interest(POIs), analyzes the spatial distribution patterns of urban functions in Beijing. Then according to the taxi GPS data with the origin and destination points(taxi-ODs), we identify the spatial and temporal pattern of the degree of urban function mix in Beijing. Finally, based on the information entropy model of the POIs and taxi-ODs, we establish a spatial entropy and a temporal entropy to quantitatively assess the degree of urban function mix, confirming by virtue of correlation analysis and regression analysis that the spatial entropy of POIs is closely associated with the temporal entropy of taxi-ODs, which proves that it is reasonable to assess the degree of urban function mix via these two entropies. As a result, the degree of urban function mix in Beijing is characterized by slowly decreasing from its core area along the 3rd and 4th Ring Roads to its periphery. In detail, there is the highest degree of urban function mix in Beijing's traditional core areas, including Zhongguancun, CBD(Central Business District), the Old Dongcheng District, the Old Xicheng District, and the area within the 2nd Ring Road; a higher degree in Wangjing area; and a low degree in Tiantongyuan and Huilongguan communities. The analytical results have initially achieved a more accurate identifi cation and quantitative evaluation on the degree of urban function mix, and can be taken as a supporting tool to analyze the comprehensiveness of urban functions. | Li Miaoyi Shen Zhenjiang Yang Tao Wang Jingyuan Kobayashi Fumihiko Li Min | 2015 | China City Planning Review2015，24，1： | 4 |

| 14 | Important mesoscale phenomena in gas phase fluidized bed ethylene polymerization显示文摘Gas phase fluidized bed processes have been widely applied to polyethylene production.In these processes,the flow,mass transfer,and reaction rate on the microscale and macroscale are strongly coupled because of the multiphase and multiscale nature of the fluidization system.Understanding mesoscale phenomena is therefore essential to the quantitative translation of the knowledge obtained from the microscale to the macroscale.This paper reviews the development of ethylene polymerization gas phase processes while focussing on studies regarding mesoscale phenomena.These include experimental characterizations,mathematical modelling and control strategies.Trends and future developments in this field are also discussed. | Jingyuan Sun Haotong Wang Sihang Tian Xiaoqiang Fan Qiang Shi Ying Liu Xiaobo Hu Yao Yang Jingdai Wang Yongrong Yang | 2020 | Particuology2020，18，1： | 3 |
| 15 | Does exercise have a protective effect on cognitive function under hypoxia? A systematic review with meta-analysis显示文摘Objective:This study aimed to examine(1)the independent effects of hypoxia on cognitive function and(2)the effects of exercise on cognition while under hypoxia.Methods:Design:Systematic review with meta-analysis.Data sources:PubMed,Scopus,Web of Science,PsychInfo,and SPORTDiscus were searched.Eligibility criteria for selecting studies:randomized controlled trials and nonrandomized controlled studies that investigated the effects of chronic or acute exercise on cognition under hypoxia were considered(Aim 2),as were studies investigating the effects of hypoxia on cognition(Aim 1).Results:In total,18 studies met our inclusionary criteria for the systematic review,and 12 studies were meta-analyzed.Exposure to hypoxia impaired attentional ability(standardized mean difference(SMD)=-0.4),executive function(SMD=-0.18),and memory function(SMD=-0.26),but not information processing(SMD=0.27).Aggregated results indicated that performing exercise under a hypoxia setting had a significant effect on cognitive improvement(SMD=0.3,95%confidence interval:0.14-0.45,I^2=54%,p<0.001).Various characteristics(e.g.,age,cognitive task type,exercise type,exercise intensity,training type,and hypoxia level)moderated the effects of hypoxia and exercise on cognitive function.Conclusion:Exercise during exposure to hypoxia improves cognitive function.This association appears to be moderated by individual and exercise/hypoxia-related characteristics. | Myungjin Jung Liye Zou Jane Jie Yu Seungho Ryu Zhaowei Kong Lin Yang Minsoo Kang Jingyuan Lin Hong Li Lee Smith Paul D.Loprinzi | 2020 | Journal of Sport and Health Science2020，9，6： | 3 |
| 16 | A new method for orbit determination: Unit vector method显示文摘In this paper, a method of orbit determination is presented according to the principle of unit vector method (UVM). The model and arithmetic are improved and it not only suits initial orbit determination with short arc data, it also suits orbit improvement with data longer. It is also suitable for orbit of any eccentricity and any inclination. It omits most partial derivatives of all the elements which must be calculated in classical differential orbit improvement (DOI), so, it is more efficient than DOI, and the accuracy of orbit determination and convergence of algorithm are also improved appreciably. | ZHANG Jing LU BenKui MA JingYuan XIA Yi ZHANG Yang | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 3 |
| 17 | Modeling and Optimization of Ethane Steam Cracking Process in An Industrial Tubular Reactor with Improved Reaction Scheme显示文摘Ethane steam cracking process in an industrial reactor was investigated.An one-demsional(1D)steady-state model was developed firstly by using an improved molecular reaction scheme and was then simulated in Aspen Plus.A comparison of model results with industrial data and previously reported results showed that the model can predict the process kinetics more accurately.In addition,the validated model was used to study the effects of different process variables,including coil outlet temperature(COT),steam-to-ethane ratio and residence time on ethane conversion,ethylene selectivity,products yields,and coking rate.Finally,steady-state optimization was conducted to the operation of industrial reactor.The COT and steam-to-ethane ratio were taken as decision variables to maximize the annual operational profit. | Mohsin Ali Liao Zuwei Yao Yang Sun Jingyuan Jiang Binbo Wang Jingdai Yang Yongrong | 2020 | China Petroleum Processing & Petrochemical Technology2020，22，4： | 2 |
| 18 | XAFS study of Cu^(2+) in aqueous solution of CuBr_2显示文摘Copper ion is the essential microelement to many organisms. In this paper, the local structure of Cu2+ in CuBr2 aqueous solutions with different concentrations are investigated by using X-ray absorption fine structure (XAFS) technique. XANES (X-ray Absorption Near Edge Structure) spectra indicate that charge transfer from Br- to Cu2+ decreases with the solution concentration, which lead to a shift of the absorption edge. The shoulder appearing at the rising edge proves to be characteristic of a tetragonal distortion. The Fourier transform magnitudes of EXAFS (Extended X-ray absorption fine structure) data of Cu species suggest that more Cu-Br bonds may exist in high concentrations. A fivefold coordination configuration like a pyramid is used as the fitting parameters. From the analysis of the coordination numbers, the proportion of Cu-O and Cu-Br is 4:1 in the saturated solution. The Br atom is on the equatorial plane of the model. The fitting results agree well with the experiment data. | DAI Binbin WANG Qian MA Jingyuan LI Jiong ZHANG Shuo HUANG Yuying HUANG Wei WU Guozhong ZOU Yang JIANG Zheng XU Hongjie | 2012 | Nuclear Science and Techniques2012，23，3： | 2 |
