| 4 | Seasonal pattern of Echinococcus re-infection in owned dogs in Tibetan communities of Sichuan, China and its implications for control显示文摘Background:Human cystic echinococcosis(CE)and alveolar echinococcosis(AE)are highly endemic in Tibetan communities of Sichuan Province.Previous research in the region indicated that domestic dog was the major source of human infection,and observations indicated that domestic dog could have more access to intermediate hosts of Echinococcus spp.:both domestic livestock(CE)viscera and small mammals(AE),in early winter and again in spring.We hypothesized that there would therefore be a significant increase in the risk of canine infection with Echinococcus spp.in these two seasons and conducted a reinfection study to investigate this further.Methods:Faecal samples were collected from owned dogs in seven townships in Ganze Tibetan Autonomous Prefecture(Sichuan Province,China),and Echinococcus spp.infection status was determined using copro-antigen ELISA.Dogs were sampled in April(spring),July(early summer),September/October(autumn/early winter)and December(winter)in 2009;and in April(spring)2010.Dogs were treated with praziquantel following each of the five sample collections to eliminate any tapeworms.Information on dog sex,age and body weight was also collected.The t-test,Fisher’s exact test,Poisson regression and logistic regression were used to compare means and prevalences,and to identify factors associated with infection status.Results:The proportion of female dogs was significantly lower than that of male dogs;female dogs had significantly higher(22.78%)baseline copro-ELISA prevalence than males(11.88%).Dog body weight,sex,age,county and previous infection status at any sampling point had no influence on the re-infection prevalence in general.Poisson regression did not found a significant influence on the re-infection prevalence due to different deworming/sampling time spans.Dogs exhibited significantly higher re-infection prevalences in spring and early summer of 2009 and in early winter between September/October and December of 2009,suggesting a higher infection pressure in these seasons comparing with other seasons.Conclusion:Following praziquantel treatment,dog body weight,sex,age,county,deworming time span and previous infection status at any sampling point had no influence on the re-infection prevalence in the region in general.The differences between re-infection prevalences were probably due to the seasonality in Echinoccocus spp.infection pressure in the region.Early winter,spring and early summer should be important seasons for optimal dog deworming intervention in these Tibetan communities. | Qian Wang Wen-Jie Yu Bo Zhong Jing-Ye Shang Liang Huang Alexander Mastin Renqingpengcuo Yan Huang Guang-Jia Zhang Wei He Patrick Giraudoux Wei-Ping Wu Philip S.Craig | 2016 | Infectious Diseases of Poverty2016，5，1： | 15 |
| 5 | Control scheme of hexagonal modular multilevel direct converter for offshore wind power integration via fractional frequency transmission system显示文摘A fractional frequency transmission system(FFTS)is a promising solution to offshore wind power integration,for which the hexagonal modular multilevel converter(Hexverter)is an attractive choice for power conversion.The Hexverter has recently been proposed to directly connect two three-phase systems of different frequencies and voltage amplitudes,with only six branches in the FFTS in that case.This paper examines for the first time the control scheme of the Hexverter when applied to offshore wind power integration via a FFTS.Firstly,the frequency-decoupled mathematical model of the Hexverter is deduced by introducing the double dq transformation.Then the branch energy of the Hexverter is analyzed in detail and the reactive power constraint equation is obtained.The corresponding control scheme is thoroughly discussed,including the inner loop current control,the outer loop voltage control in both grid-connected mode and passive mode,and a novel optimization method to minimize the circulating current in the Hexverter.Finally,a simulation model of offshore wind power integration via a 4-terminal FFTS based on the Hexverter is built in MATALB/Simulink to verify the feasibility of Hexverter and the effectiveness of the control scheme proposed in this paper. | Yongqing MENG Bo LIU Huiyong LUO Shuonan SHANG Haitao ZHANG Xifan WANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，1： | 12 |
| 6 | Effects of Chinese herbal medicine Xiangbin prescription on gastrointestinal motility显示文摘AIM To investigate the effects of Xiangbin prescription(XBP), a Chinese herbal concoction, on gastrointestinal motility.METHODS Forty healthy volunteers were recruited for this randomized controlled trial of XBP. Antroduodenojejunal manometry was used to monitor gastrointestinal motility in these subjects. After the subjects had fasted for at least 12 h, XBP(n = 30) or placebo(n = 10) was orally administrated and gastrointestinal motility was recorded for 4 h. Plasma motilin and ghrelin were measured by enzyme-linked immunosorbent assay.RESULTS Oral administration of XBP significantly increased the amplitude of duodenal contractions [19.5(13.0-26.7) vs 16.9(12.3-23.9), P < 0.05], jejunal contractions [18.3(15.3-25.0) vs 15.4(11.7-23.9), P < 0.01], and the motility index of duodenal contractions [522.0(146.0-139.0) vs 281.0(76.5-1006.0), P < 0.01] in phase Ⅱ of the migratory motor complex(MMC), which subsequently initiated the MMC cycle [74.0(30.0-118.0) vs 116.5(24.0-219.0), P < 0.05], shortened the duration of phase I of the MMC [42.0(0.0-90.0) vs 111.5(42.0-171.0), P < 0.01], and lengthened the duration of phase Ⅱ of the MMC [120(21-240) vs 58(16-170), P < 0.01] compared to the duration before XBP administration. There were significant differences in the amplitude of jejunal contractions [19.8(14.0-30.0) vs 18.0(13.0-28.5), P < 0.05], the motility index of duodenal contractions [236.0(115.0-306.0) vs 195.0(109.0-310.0), P < 0.05], and jejunal contractions [214.0(95.0-403.0) vs 178.0(55.0-304.0), P < 0.01] in phase Ⅲ of the MMC. Oral administration of XBP greatly increased plasma motilin(57.69 ± 9.03 vs 49.38 ± 8.63, P < 0.01) and ghrelin(279.20 ± 104.31 vs 238.73 ± 115.59, P < 0.01) concentrations compared to concentrations after oral administration of the placebo.CONCLUSION XBP can stimulate duodenal and jejunal motility and increase the concentrations of plasma motilin and ghrelin. The clinical applicability of XBP in treating GDIM deserves investigation. | Zhi Jiang Li-Xing Cao Bo Liu Qi-Cheng Chen Wen-Fan Shang Lu Zhou Dan-Yan Li De-An Guo Zhi-Qiang Chen | 2017 | World Journal of Gastroenterology2017，23，16： | 11 |
| 7 | Classification and regionalization of the forming environment of windblown sand disasters along the Tarim Desert Highway显示文摘Through the systematic field survey and observations, the factor quantification as well as setting the criteria, the sand disaster-forming environment along the Tarim Desert Highway can be divided into four grades by the classification and regionalization based on fuzzy mathematics. The length of the regions with significant sand disaster accounted for 37.1% of the total highway length. Particularly, the area along the Tarim Desert Highway, based on the sand disaster-forming environment classification as well as the difference in the five basic landform units along the highway, combined with the difference of wind regime, can be divided into five regions, in which the length of the regions suffering severe sand damage occupied 64.3% of the total highway length. In addition, the index of disaster formation grade along the highway decreased from north to south, showing a repeated spatial pattern in small length scales. | LEI JiaQiang LI ShengYu FAN DongDong ZHOU HongWei GU Feng QIU YongZhi XU Bo LIU Shang DU WenYi YAN ZengHui WANG YongChang | 2008 | Chinese Science Bulletin2008，53，S2： | 11 |
| 8 | A multiplex PCR for differential detection of Echinococcus granulosus sensu stricto,Echinococcus multilocularis and Echinococcus canadensis in China显示文摘Background:Echinococcosis caused byEchinococcus is one of the most major infectious diseases in north-west highland of China.E.granulosus sensu strict,E.multilocularis,andE.canadensis are known to be the only three species related to human health transmitting in the areas.To achieve targeted treatment and control of echinococcosis,the accurate identification and discrimination of the species are important.However,currently the available diagnostic approaches do not present ideal results either in accuracy or efficiency.Methods:In the study,a set of primers were designed to aim at the three human-pathogenicEchinococcus species in China.The one-step multiplex PCR assay was developed and evaluated for the specificity and sensitivity.A total of 73parasitic lesions and 41 fecal materials obtained from human and various animals collected in the clinic and the field were tested to assess the applicability of this method.Results:The multiplex PCR effectively detected the individual DNA from the targeted species and their random mixtures generating with distinguishable expected size of products.The detection limit of the assay for each of the three species was 5 pg/μl when they were tested separately.When DNA mixtures of the targeted species containing the same concentration were used as templates,the lowest amount of DNA which can be detected was 50 pg/μl,10 pg/μl and 5 pg/μl forE.granulosus s.s.,E.multilocularis,andE.canadensis respectively.No cross-reactivity was observed when DNA from eight genetically close species was used as control templates.The multiplex PCR identifications of all samples were in line with the original sequencing results except for those infected withE.shiquicus,which showed negative signals in the developed assay.Of all the tested stool materials,16 were previously found positive forEchinococcus by visual and microscopic examination.Among these 16 samples,13 were confirmed by the multiplex PCR,and the other three tested negative.Additionally,the multiplex PCR identified another 14 positive feces from the remained 25 stool samples which absence of worms.Conclusions:The developed multiplex PCR shows advantages in fast diagnosis and large-scale epidemiological investigation,which proven to be a promising tool utilized in clinic and surveillance system. | Jing-Ye Shang Guang-Jia Zhang Sha Liao Yan Huang Wen-Jie Yu Wei He Guang-You Yang Tiao-Ying Li Xing-Wang Chen Bo Zhong Qian Wang Qi Wang Rui-Rui Li Hao Wang | 2019 | Infectious Diseases of Poverty2019，8，4： | 11 |
| 9 | Characters and Species Diversity of Torreya fargesii Franch. Community in the Jinfo Mountains显示文摘This paper aims to study characteristics and biodiversity of the Torreya fargesii community in the Jinfo Mountains to provide baseline information related to the protection of T. fargesii. The results indicated that among the 5 plots(100 m2 each) set along an altitudinal gradient, 176 species of vascular plants, 136 genera and 64 families were recorded. These included 7 species of pteridophytes, 6 genera and 4 families, 3 species of gymnosperms, 3 genera and 2 families, and 166 species of angiosperms, 127 genera and 58 families. The community physiognomy was mainly dominated by phanerophytes with medium-sized herbaceous and simple leaves. The proportions of phanerophytes among the fl oristic spectrum, frequency spectrum and vegetational spectrum are 68.75%, 73.13% and 67.48% respectively. The vertical structure can be divided into the shrub and herb layers in this community. The dominant species in shrub layer were T. fargesii, Zanthoxylum ovalifolium, Rubus coreanus, Kerria japonica, Cotoneaster horizontalis etc.. The dominant herbs included Miscanthus sinensis, Carex gibba, Artemisia lactifl ora, Pteridium aquilinum var. latiusculum, Pilea notata, Aster ageratoides etc.. Species richness(S) and the Simpson(D), Shannon-Wiener(H') and Pielou evenness(Jsw) indices of shrub layer species richness are higher than those of the herb layer; the distribution of the species in the community is obviously uneven. The species richness and diversity indices increase with the rising altitude. | JIANG Bo WANG Jianhua SHANG Jin ZHOU Xianrong | 2016 | Journal of Landscape Research2016，8，2： | 10 |

| 11 | Rapid Optimization of Tension Distribution for Cable-Driven Parallel Manipulators with Redundant Cables显示文摘The solution of tension distributions is infinite for cable-driven parallel manipulators(CDPMs) with redundant cables. A rapid optimization method for determining the optimal tension distribution is presented. The new optimization method is primarily based on the geometry properties of a polyhedron and convex analysis. The computational efficiency of the optimization method is improved by the designed projection algorithm, and a fast algorithm is proposed to determine which two of the lines are intersected at the optimal point. Moreover, a method for avoiding the operating point on the lower tension limit is developed. Simulation experiments are implemented on a six degree-of-freedom(6-DOF) CDPM with eight cables, and the results indicate that the new method is one order of magnitude faster than the standard simplex method. The optimal distribution of tension distribution is thus rapidly established on real-time by the proposed method. | OUYANG Bo SHANG Weiwei | 2016 | Chinese Journal of Mechanical Engineering2016，29，2： | 8 |
| 12 | Influence of genotypes and environmental factors on leaf triterpenoid content and growth of Cyclocarya paliurus显示文摘Cyclocarya paliurus, an economically valuable tree species, has traditionally been used as a nutraceutical food or medicine in China. However, limited information is available on its genotype selection and cultivation under a wide range of environmental conditions for growth and targeted health-promoting substances. We studied the effects of genotype and environment, and their interaction on leaf triterpenoid content and tree growth for 12 genotypes of C. paliurus grown at four sites. We quantified the correlation between leaf triterpenoid accumulation and tree growth. The contents of cyclocaric acid B, cyclocarioside I, and arjunolic acid ranged from 0.06 to 3.89, 0 to 3.71, and 0.65 to 8.86 mg g^-1, respectively. Three individual triterpenoids were primarily influenced by genotype (variation ranged from 53.7 to 68.0%), while environment accounted for most of the variation in total triterpenoid content and tree growth (71.3–89.5%). Most tested environmental parameters were significantly correlated to total triterpenoid content, but not to the contents of the individual triterpenoids measured. Growth in tree height and diameter at breast height were significantly negatively correlated with total triterpenoid content but were non-significantly correlated with individual triterpenoid contents. We conclude that genotypic selection, manipulation of environmental conditions, and implementation of appropriate silvicultural operations would be important strategies for increasing the accumulation of health-promoting phytochemicals. | Bo Deng Shengzuo Fang Xulan Shang Xiangxiang Fu Wanxia Yang | 2019 | Journal of Forestry Research2019，30，3： | 7 |
| 13 | Large variability in ambient ozone sensitivity across 19 ethylenediurea-treated Chinese cultivars of soybean is driven by total ascorbate显示文摘The sensitivity of Chinese soybean cultivars to ambient ozone(O3) in the field is unknown,although soybean is a major staple food in China. Using ethylenediurea(EDU) as an O3 protectant, we tested the gas exchange, pigments, antioxidants and biomass of 19 cultivars exposed to 28 ppm·hr AOT40(accumulated O3 over an hourly concentration threshold of40 ppb) over the growing season at a field site in China. By comparing the average biomass with and without EDU, we estimated the cultivar-specific sensitivity to O3 and ranked the cultivars from very tolerant(< 10% change) to highly sensitive(> 45% change), which helps in choosing the best-suited cultivars for local cultivation. Higher lipid peroxidation and activity of the ascorbate peroxidase enzyme were major responses to O3 damage, which eventually translated into lower biomass production. The constitutional level of total ascorbate in the leaves was the most important parameter explaining O3 sensitivity among these cultivars. Surprisingly, the role of stomatal conductance was insignificant. These results will guide future breeding efforts towards more O3-tolerant cultivars in China, while strategies for implementing control measures of regional O3 pollution are being implemented. Overall, these results suggest that present ambient O3 pollution is a serious concern for soybean in China, which highlights the urgent need for policy-making actions to protect this critical staple food. | Lijun Jiang Zhaozhong Feng Lulu Dai Bo Shang Elena Paoletti | 2018 | Journal of Environmental Sciences2018，30，2： | 7 |
| 14 | A more consistent intraluminal rhesus monkey model of ischemic stroke显示文摘Endovascular surgery is advantageous in experimentally induced ischemic stroke because it causes fewer cranial traumatic lesions than invasive surgery and can closely mimic the pathophysiology in stroke patients. However, the outcomes are highly variable, which limits the accuracy of evaluations of ischemic stroke studies. In this study, eight healthy adult rhesus monkeys were randomized into two groups with four monkeys in each group: middle cerebral artery occlusion at origin segment(M1) and middle cerebral artery occlusion at M2 segment. The blood flow in the middle cerebral artery was blocked completely for 2 hours using the endovascular microcoil placement technique(1 mm × 10 cm)(undetachable), to establish a model of cerebral ischemia. The microcoil was withdrawn and the middle cerebral artery blood flow was restored. A reversible middle cerebral artery occlusion model was identified by hematoxylin-eosin staining, digital subtraction angiography, magnetic resonance angiography, magnetic resonance imaging, and neurological evaluation. The results showed that the middle cerebral artery occlusion model was successfully established in eight adult healthy rhesus monkeys, and ischemic lesions were apparent in the brain tissue of rhesus monkeys at 24 hours after occlusion. The rhesus monkeys had symptoms of neurological deficits. Compared with the M1 occlusion group, the M2 occlusion group had lower infarction volume and higher neurological scores. These experimental findings indicate that reversible middle cerebral artery occlusion can be produced with the endovascular microcoil technique in rhesus monkeys. The M2 occluded model had less infarction and less neurological impairment, which offers the potential for application in the field of brain injury research. | Bo Zhao Guowei Shang Jian Chen Xiaokun Geng Xin Ye Guoxun Xu Ju Wang Jiasheng Zheng Hongjun Li Fauzia Akbary Shengli Li Jing Lu Feng Ling Xunming Ji | 2014 | Neural Regeneration Research2014，9，23： | 6 |
| 15 | Toward Evidence-Based Chinese Medicine:Status Quo,Opportunities and Challenges显示文摘How to test the treatments of Chinese medicine(CM) and make them more widely accepted by practitioners of Western medicine and the international healthcare community is a major concern for practitioners and researchers of CM.For centuries,various approaches have been used to identify and measure the efficacy and safety of CM.However,the high-quality evidence related to CM that produced in China is still rare.Over the recent years,evidence-based medicine(EBM) has been increasingly applied to CM,strengthening its theoretical basis.This paper reviews the past and present state of CM,analyzes the status quo,challenges and opportunities of basic research,clinical trials,systematic reviews,clinical practice guidelines and clinical pathways and evidence-based education developed or conducted in China,pointing out how EBM can help to make CM more widely used and recognized worldwide. | CHEN Yao-long ZHAO Chen ZHANG Li LI Bo WU Chuan-hong MU Wei WANG Jia-ying YANG Ke-hu LI You-ping CHEN Chiehfeng WANG Yong-yan WANG Chen BIAN Zhao-xiang SHANG Hong-cai | 2018 | Chinese Journal of Integrative Medicine2018，24，3： | 6 |
| 16 | Emerging Flexible Thermally Conductive Films:Mechanism,Fabrication,Application显示文摘Effective thermal management is quite urgent for electronics owing to their ever-growing integration degree,operation frequency and power density,and the main strategy of thermal management is to remove excess energy from electronics to outside by thermal conductive materials.Compared to the conventional thermal management materials,flexible thermally conductive films with high in-plane thermal conductivity,as emerging candidates,have aroused greater interest in the last decade,which show great potential in thermal management applications of next-generation devices.However,a comprehensive review of flexible thermally conductive films is rarely reported.Thus,we review recent advances of both intrinsic polymer films and polymer-based composite films with ultrahigh in-plane thermal conductivity,with deep understandings of heat transfer mechanism,processing methods to enhance thermal conductivity,optimization strategies to reduce interface thermal resistance and their potential applications.Lastly,challenges and opportunities for the future development of flexible thermally conductive films are also discussed. | Chang‑Ping Feng Fang Wei Kai‑Yin Sun Yan Wang Hong‑Bo Lan Hong‑Jing Shang Fa‑Zhu Ding Lu Bai Jie Yang Wei Yang | 2022 | Nano-Micro Letters2022，14，8： | 6 |

| 18 | The influence of atmospheric Hg on Hg contaminations in rice and paddy soil in the Xunyang Hg mining district,China显示文摘To date, the Xunyang mercury(Hg) mining district is the only ongoing large-scale Hg mining district in China. To understand the influence of Hg contamination mode from the Hg mining and smelting activities, 27 sampling sites in the Xunyang Hg mining district were chosen in this study. Total gaseous mercury(TGM) in ambient air was measured using a Lumex-RA915 automatic Hg analyzer in2011. Rice samples and soil samples from rhizosphere were collected systematically and simultaneously. Total Hg(THg) and methylmercury(Me Hg) concentrations in rice grain and soil samples and Hg speciation with modified sequential selective extractions were measured. The local environment was seriously polluted with Hg. The TGM(302 ± 376 ng·m-3, ranging from 24 to 2220 ng·m^(-3)) in the local ambient air, THg(28 ± 30 mg·kg^(-1), ranging from 0.31 to 121 mg·kg^(-1)) and Me Hg(2.3 ± 1.9 lg·kg^(-1),ranging from 0.24 to 8.9 lg·kg^(-1)) in soil samples were at the sample level with Hg contaminated area. The THg concentration(26 ± 16 lg·kg^(-1)ranging from 4.5 to 71 lg·kg^(-1)) in most of the rice grain samples clearly exceeds the threshold level(20 lg·kg^(-1)) in the Chinese national guidelines for cereals(NY 861-2004). The inorganic mercury(IHg)(9.1 ± 5.6 lg·kg^(-1), ranging from 1.2 to 24 lg·kg^(-1)) and Me Hg(14 ± 9.8 lg·kg^(-1), ranging from 2.1 to 59 lg·kg^(-1))concentration in rice grain samples were at the same level with Hg contaminated area. The main species of Hg in paddy soils reveal strong complex Hg and residue Hg. According to the correlation analysis, a Hg pollution mode from local Hg mining and smelting was hypothesized, including Hg emission, transportation, methylation, and uptake process. | Ming Ao Bo Meng Atindra Sapkota Yonggui Wu Xiaoli Qian Guangle Qiu Shunqing Zhong Lihai Shang | 2017 | Acta Geochimica2017，36，2： | 5 |
| 19 | Gene expression of vascular endothelial growth factor A and hypoxic adaptation in Tibetan pig显示文摘Background: Vascular endothelial growth factor A(VEGFA) can induce endothelial cell proliferation, promote cell migration, and inhibit apoptosis. These processes play key roles in physiological blood vessel formation and pathological angiogenesis.Methods: In this study, we examined VEGFA gene expression in the heart, liver, and kidney of Tibetan pigs(TP), Yorkshire pigs that migrated to high altitudes(YH), and Yorkshire pigs that lived at low altitudes(YL).We used PCR and Sanger sequencing to screen for single nucleotide polymorphisms(SNPs) in 5'-flanking DNA and exons of the VEGFA gene. Quantitative real-time PCR and western blots were used to measure expression levels and PCR products were sequenced.Results: Results showed that the VEGFA m RNA and protein expression in heart, liver and kidney of TP was higher than that in YH and YL. In addition, the m RNA sequence of the pig VEGFA gene was conserved among pig breeds, and only five SNPs were found in the 5'-flanking region of the VEGFA gene, the allele frequency distributions of the 5 SNPs were not significantly different between the TP, Yorkshire(YL), and Diannan small-ear(DN) pig populations.Conclusion: In conclusion, the Tibetan pig showed high levels of VEGFA gene expression in several hypoxic tissues, which suggests that the VEGFA gene may play a major functional role in hypoxic adaptation. | Bo Zhang Yangzong Qiangba Peng Shang Yunfeng Lu Yuzeng Yang Zhixiu Wang Hao Zhang | 2016 | Journal of Animal Science and Biotechnology2016，7，4： | 4 |
| 20 | Combustor design and performance prediction based on parametric model显示文摘By combining the three-dimensional model software and grid generation software,the combustor parametric model and high quality and high speed gridding in the full flow field has been realized.Based on the research of the parametric modeling,an optimizing design,CFD analysis and performance prediction of the combustor have been accomplished,and the rule of the combustor performance variation with structural parameters was presented.The results show that the combustor capability has no significant change with the radial swirler parameters and the primary holes area.The combustor capability has significant change with position and profile of the primary holes and dilution holes,and the combustor outlet temperature profile and emission change greatly when the total hole area of the burnerinnerliner changes.The parametric model method is helpful to provide a fast design method for the aero-engine combustor design. | LI Feng SHANG Shou-tang GUO Rui-qing CHENG Ming TANG Zheng-fu SONG Bo | 2014 | 航空动力学报2014，29，4： | 4 |
