| 1 | Surface runoff processes and sustainable utilization of water resources in Manas River Basin, Xinjiang, China显示文摘Water is the important resource to guarantee the existence and development of oases in arid areas. To improve the utilization efficiency of water resources in Manas River Basin, this paper investigated the trends and periods of runoff based on the runoff and climate data for the past 50 years. Subsequently, with the socioeconomic and water resources data, we studied a comprehensive evaluation on the water security in this area. The results indicated that the stream flows in the three hydrological stations of Hongshanzui, Kensiwat and Bajiahu have significantly increased and undergone abrupt changes, with periods of 18 and 20 years. According to assessment, water security in the Manas River Basin was at an unsafe level in 2008. In criterion layer, the ecological security index and the index of supply-demand situation are both at the relatively secure level; the quantity index and socioeconomic index of water resources are at the unsafe level and basic security level, respectively. Therefore, in order to achieve sustainable economic and social development within the Manas River Basin, it is vital to take a series of effective measures to improve the status of water security. | HongBo LING HaiLiang XU JinYi FU XinHua LIU | 2012 | Journal of Arid Land2012,4,3: | 18 |
| 2 | MIKC^(C)-type MADS-box genes in Rosa chinensis: the remarkable expansion of ABCDE model genes and their roles in floral organogenesis显示文摘MIKC^(C)-type MADS-box(MIKC^(C))genes encode transcription factors that have crucial roles in controlling floral organogenesis and flowering time in plants.Although this gene family has been well characterized in many plant species,its evolutionary and comprehensive functional analysis in rose is lacking.In this study,58 non-redundant MIKC^(C)uni-transcripts were extensively identified from rose transcriptomes.Phylogenetic analysis placed these genes into 12 clades with their Arabidopsis and strawberry counterparts,and revealed that ABCDE model(including AP1/FUL,AP3/PI,AG,and SEP clades),and SOC1 and AGL6 clade genes have remarkably expanded in Rosa chinensis,whereas genes from the FLC and AGL17 clades were undetectable.Sequence alignments suggest that the AP3/PI clade may contribute to more specific functions in rose due to a high variation of amino acid residues within its MADS-box domains.A comparative analysis of gene expression in specific floral organ differentiation stages and floral organs between R.chinensis cv.Old Blush and the closely related mutant genotype R.chinensis cv.Viridiflora(floral organs mutated into leaf-like structures)further revealed the roles of ABCDE model genes during floral organogenesis in rose.Analysis of co-expression networks provided an overview of the regulatory mechanisms of rose MIKC^(C)genes and shed light on both the prominent roles of AP3/PI clade genes in floral organogenesis and the roles of RcAGL19,RcAGL24,and RcSOC1 in regulating floral transition in rose.Our analyses provide an overall insight of MIKC^(C)genes in rose and their potential roles in floral organogenesis. | Jinyi Liu Xiaodong Fu Yuwei Dong Jun Lu Min Ren Ningning Zhou Changquan Wang | 2018 | Horticulture Research2018,5,1: | 7 |
| 3 | Tumorigenic bacteria in colorectal cancer:mechanisms and treatments显示文摘Colorectal cancer(CRC)is the third most common and the second most fatal cancer.In recent years,more attention has been directed toward the role of gut microbiota in the initiation and development of CRC.Some bacterial species,such as Fusobacterium nucleatum,Escherichia coli,Bacteroides fragilis,Enterococcus faecalis,and Salmonella sp.have been associated with CRC,based upon sequencing studies in CRC patients and functional studies in cell culture and animal models.These bacteria can cause host DNA damage by genotoxic substances,including colibactin secreted by pks+Escherichia coli,B.fragilis toxin(BFT)produced by Bacteroides fragilis,and typhoid toxin(TT)from Salmonella.These bacteria can also indirectly promote CRC by influencing host-signaling pathways,such as E-cadherin/β-catenin,TLR4/MYD88/NF-κB,and SMO/RAS/p38 MAPK.Moreover,some of these bacteria can contribute to CRC progression by helping tumor cells to evade the immune response by suppressing immune cell function,creating a proinflammatory environment,or influencing the autophagy process.Treatments with the classical antibacterial drugs,metronidazole or erythromycin,the antibacterial active ingredients,M13@Ag(electrostatically assembled from inorganic silver nanoparticles and the protein capsid of bacteriophage M13),berberine,and zerumbone,were found to inhibit tumorigenic bacteria to different degrees.In this review,we described progress in elucidating the tumorigenic mechanisms of several CRC-associated bacteria,as well as progress in developing effective antibacterial therapies.Specific bacteria have been shown to be active in the oncogenesis and progression of CRC,and some antibacterial compounds have shown therapeutic potential in bacteria-induced CRC.These bacteria may be useful as biomarkers or therapeutic targets for CRC. | Sha Li Jinyi Liu Xiangjin Zheng Liwen Ren Yihui Yang Wan Li Weiqi Fu Jinhua Wang Guanhua Du | 2022 | Cancer Biology & Medicine2022,19,2: | 3 |
| 4 | Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors. | Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang | 2019 | Asian Journal of Urology2019,6,1: | 2 |
| 5 | Energy and Parameter Analysis of SOFC System for Hydrogen Production from Methane Steam Reforming显示文摘In this paper, an integrated system of solid oxide fuel cell(SOFC) and methane steam reforming for hydrogen production is proposed. The mathematical model of the coupled integrated system is studied by COMSOL and Aspen software, and the energy analysis of the integrated system is carried out. The system recovers and reuses the waste heat of the SOFC stack through the heat exchanger, which can realize the cascade efficient use of energy. By adjusting the different reforming temperatures, steam-to-carbon ratio and SOFC operating temperature of methane steam reforming to produce hydrogen, the parameters that have a greater impact on the system are studied. The research results show that as the steam-to-carbon ratio and reformer operating temperature increase, the net output power and efficiency of the system increase. When the fuel cell operating temperature is 800℃, the output power and efficiency of the system reach the maximum values of 899.93 W and 52.52%, respectively. Increasing the operating temperature of SOFC helps to improve the efficiency of fuel cells, but the efficiency of the integrated system of methane steam reforming hydrogen production and SOFC first increases and then decreases. This system can realize the direct coupling between the SOFC reactor subsystem and the methane steam reforming hydrogen production system under optimized conditions, which has reference significance for the actual operating conditions of the coupled system. | DENG Meilong LIU Jinyi ZHANG Xiaosong LI Jinsong FU Lirong | 2022 | Journal of Thermal Science2022,31,6: | 1 |

| 7 | Existence and Gevrey regularity for a two-species chemotaxis system in homogeneous Besov spaces显示文摘We study the Cauchy problem of a two-species chemotactic model. Using the Fourier frequency localization and the Bony paraproduct decomposition, we establish a unique local solution and blow-up criterion of the solution, when the initial data(u0, v0, w0) belongs to homogeneous Besov spaces˙B^(-2+3/p)_(p,1)(R^3) ×˙B^(-2+3/r)_(r,1)(R^3) ×˙B^(3/q)_(q,1)(R^3) for p, q and r satisfying some technical assumptions. Furthermore, we prove that if the initial data is sufficiently small, then the solution is global. Meanwhile, based on the so-called Gevrey estimates, we particularly prove that the solution is analytic in the spatial variable. In addition, we analyze the long time behavior of the solution and obtain some decay estimates for higher derivatives in Besov and Lebesgue spaces. | YANG MingHua FU ZunWei SUN JinYi | 2017 | Science China Mathematics2017,60,10: | 0 |
| 8 | Credit Spreads,Probability of Default and Debt Risk Measurement of Prefectural Governments in China:2014-2017显示文摘In this paper,the concepts of probability of default,loss given default and expected loss in the internal ratings-based approach are introduced into the measurement of local government debt risk.Based on issuing interest rate and credit spreads of provincial government bonds,the default probability models of general debt and special debt are constructed and estimated,and the general and special debt risk of 333 prefectural governments in China from 2014 to 2017 are estimated respectively,and their regional distribution and changes are analyzed.The conclusions are as follows:Both general and special debt risk are different among regions.In terms of vertical changes in 2014-2017,debt risk has increased on the whole,but this increase has been driven more by the increase in the size of the debt,with no significant change in the probability of default,and the debt risk is concentrated in a small number of prefectural governments.The general debt risk accounts for about two-thirds of the total debt risk,the special debt risk accounts for about one-third,and this proportion structure is basically unchanged in 2014-2017.Based on the above conclusions,this paper puts forward corresponding policy recommendations for governance and control of local debt risk. | Weitao Diao Jinyi Fu Huijie Li | 2019 | China Finance and Economic Review2019,8,3: | 0 |
| 9 | Constructing B-rep Solid Model from Cubic Volume Cells显示文摘The paper introduces a method for displaying cubic volume cells (voxels) resulting frompartitioning given objectS with orthogonal planes for finite difference calculation. The method representS ablock of voxels as a B-rep solid model and conStrUcts the B-rep geometric clementS with an approach frombottom to up. Once the B-rep model is established, it is efficient in displaying because inner voxels areomitted and many coplanar facetS are merged together. By displaying the interSeCtion lines of theconstructed B-reP model and the partitioning planes, the tessellation image can be generated. | Liu Jinyi Fu Guangri(Dept of Computer Science & Technology, Fushun Petroleum Institute, Fushun, 113001)Maekawa Electric Steel Casting Co., Fukuoka, 800-03, Japan) | 1999 | Computer Aided Drafting,Design and Manufacturing1999,9,1: | 0 |
