| 1 | Validation of an agricultural non-point source(AGNPS)pollution model for a catchment in the Jiulong River watershed,China显示文摘测试并且评估农业非点来源(AGNPS ) 的这研究为 Wuchuan 集水的模型,在 Jiulong 河分水岭的一个典型农业区域,福建省, China.The AGNPS 模型在十暴风雨上与观察数据为学习区域被校准并且验证。当二暴风雨上的数据被用于模型的确认时,在 2002 的八暴风雨上的数据被用于刻度。就在一个长期的系列上的水质数据的缺乏而言,一个新奇方法,把内部嵌套的集水与它的包围集水作比较,被用来补充不太长期的系列数据。AGNPS 模型的双刻度和确认被这比较获得。结果显示相关系数为流量是 0.99 和 0.98,分别地, 0.94 和 0.95 大集水和小集水为山峰流量评价并且 0.76 为小集水的沉积仅仅。每个相关系数为为二集水的一样的事件是同类的。与沉积收益和微粒磷的例外,山峰流量率和另外的营养素很好被预言。敏感分析证明土壤保持服务曲线数字和降雨数量是最敏感的参数,它导致了高产量 variations.Erosivity,另外的参数几乎没在水文学和优秀产量上有小影响。 | LIU Jianchang ZHANG Luoping ZHANG Yuzhen HONG Huasheng DENG Hongbing | 2008 | Journal of Environmental Sciences2008，20，5： | 13 |
| 2 | Perovskite LaFeO_3 supported bi-metal catalyst for syngas methanation显示文摘LaFeO3 perovskite supported Ni and Ni-Fe catalysts were prepared and applied to methanation reaction of syngas.Two preparation methods were employed.One was one-step citrate complexing method,and the other was a two step method using citrate complexing method to produce LaFeO3 and followed by loading nickel oxide on it with impregnation.The structure evolution of the sample as prepared was investigated by XRD,TPR and TEM techniques.For the former,the chemical composites of the calcined sample are NiO-Fe2O3/LaFe1-xNix O3.After reduction and reaction of CO methanation,its composites convert to Fe-Ni@Ni/LaFeO3-La2O2CO3,in which Fe-Ni@Ni is metal particles in nano-size composed of nickel core and Fe-Ni alloy shell.For the latter,the chemical composites of the calcined sample are NiO/LaFeO3; and after reduction and reaction of CO methanation,its chemical composites change to Ni/LaFeO3.Ni/LaFeO3 catalyst is a little more active, while Fe-Ni@Ni/LaFeO3-La2O2CO3 is much more stable and shows very good resistance to carbon deposition.In this work it is aimed to show that the structure and composites of the catalysts can be tailored using perovskite-type oxide as precursor prepared with different methods and conditions.Therefore,it is a promising route to prepare supported bi-metal catalysts in nano-size for a lot of metals with desired catalytic performances. | Hong Wang Yuzhen Fang Yuan Liu Xue Bai | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 5 |

The indispensability of each form has been studied and is described in this paper. Through analysis of the reliability of the two basic forms, reliability models of the organization management chain in the series connection state and the mixed state of both series connection and parallel connection have been set up. | Feng Jingchun Zhou Yang Hong Yuzhen Zhao Shixin Ren Xiaoqiang | 2008 | Water Science and Engineering2008，1，4： | 3 |
| 4 | 奥曲肽持续皮下泵入治疗恶性肠梗阻的临床观察(英文)显示文摘Objective: The aim of the study was to observe the effectiveness of continuously subcutaneous-pumped octreotide infusion in palliative treatment of malignant bowel obstruction (MBO).Methods: Clinical data were retrospectively analyzed in 26 carcinoma patients complicated with MBO,in the Affiliated Hospital of Liaoning University of Traditional Chinese Medicine,China,from March 2007 to April 2009.All 26 carcinoma patients with MBO were divided into two groups: the controlling group (CG,routine therapy,15 patients) and the octreotide group (OG,11 patients).The octreotide group received routine therapy combined with octreotide (0.3 mg/d) by 24 hours continuously subcutaneous octreotide infusion.The changes of curative effectiveness related to symptoms,the times of recovering exsufflation and defecation,the average drain of gastrointestinal drainage tube,the duration of gastrointestinal drainage tube and the rate of extubation,were observed and compared between the two groups.Results: After treatment,remarkable changing rates of MBO related symptoms were 81.8% (9/11) in OG,and 46.7% (7/15) in CG (P < 0.05).The 78% of SG and 30% of CG recovered the exsufflation and defecation,and the mean times they needed were 3.2 d and 5.8 d,respectively (P < 0.05).The durations of gastrointestinal drainage tube of OG and CG were (5 ± 1.2) d and (10 ± 2.3) d,respectively,and the rates of extubation were 54.5% and 20%,respectively.The improvement rate in the octreotide group was better than that in the controlling group and the difference was significant (72.7% and 26.7%,P < 0.05).Conclusion: The administration of octreotide in combination with routine treatment can be very effective in the treatment of MBO.It can relieve the symptoms of MBO effectively and improve the quality of life of the end-stage patients.It has provided one kind of new treating thought and method for treatment of malignant bowel obstruction. | Dongfeng Yin Yin Zhu Yuqing Xing Hong Gao Yuzhen Pan Lin Pan Guangyi Tang Xiangrong Xing Lijiang Zhou | 2011 | The Chinese-German Journal of Clinical Oncology2011，10，1： | 2 |
| 5 | UPLC-Q-TOF/MS-based metabolomics reveals modulatory effects of Mesona chinensis Benth polysaccharide in liver injury mice induced by cyclophosphamide显示文摘The main purpose of this study was to investigate the improvement effect of Mesona chinensis Benth polysaccharide(MP)on cyclophosphamide(CTX)induced liver injury in mice.To explore metabolic profile of liver tissue and feces among normal group,CTX-induced group and MP management group based on metabolomics method by using UPLC-Q-TOF/MS.The results showed that MP could alleviate liver injury and promote the production of short chain fatty acids(SCFAs),with the best dose of 200 mg/kg·body weight(bw).The principal component analysis(PCA)and orthogonal partial least squares discriminant analysis(OPLSDA)scores plots of the liver and feces samples showed a clear separation among normal,model and highdose of MP(MPH).There were 18 endogenous metabolites in liver and 29 endogenous metabolites in feces,which were mainly involved in 8 metabolic pathways:taurine and hypotaurine metabolism,phenylalanine metabolism,α-linolenic acid metabolism,tricarboxylic acid(TCA)cycle,phenylalanine,tyrosine and tryptophan biosynthesis,arachidonic acid metabolism,sphingolipid metabolism as well as tryptophan metabolism.Moreover,a common metabolite arachidonic acid was observed in liver and feces samples.These endogenous metabolites may be considered to be MP’s response to liver protection.It will help to further understand the mechanism of MP and provide a basis for further research. | Yuzhen Hong Mingyue Shen Qiang Yu Yi Chen Jianhua Xie | 2023 | Food Science and Human Wellness2023，12，2： | 2 |
| 6 | Mesona chinensis Benth polysaccharides alleviates liver injury by beneficial regulation of gut microbiota in cyclophosphamide-induced mice显示文摘There are a number of health benefits of Mesona chinensis Benth polysaccharide(MP),but little is known about its hepatoprotective effect and effect on gut microbiota composition in mice with liver damage induced by cyclophosphamide(CTX).This study indicated that MP supplementation effectively inhibited the production of serum aspartate aminotransferase(AST)and alanine aminotransferase(ALT),enhanced liver antioxidant capacity and repaired liver damage in mice caused by CTX.The release of inflammatory cytokines in liver and the concentration of lipopolysaccharide(LPS)in serum were decreased,and the level of short chain fatty acids(SCFAs)in colon was increased after MP administration.Those effects may be correlated with the regulation of the gut microbiota.Importantly,MP restrained liver inflammatory responses induced by CTX may via increasing the SCFAs-producing bacteria family Ruminococcaceae and reduced LPS-producing bacteria genus Bacteroides.In short,the prevention of CTX-induced liver injury by supplementing MP is achieved at least in part by regulating the community structure of the gut microbiota,and MP is expected to be a potential prebiotic to treat and prevent liver diseases. | Yuzhen Hong Mingyue Shen Lixin Huang Ting Wu Jianhua Xie | 2022 | Food Science and Human Wellness2022，11，1： | 2 |

| 14 | INSULATOR TO SUPERCONDUCTOR TRANSITION OF Pb DOPED 2201 SINGLE CRYSTAL IN Bi-SYSTEM BY OXYGEN DEFICIENCY显示文摘Flux method was used to grow large 2201 single crystal in Bi-Sr-Cu oxide.The as-grown crystal was nonsuperconductor and showed semiconductivity in resistivity curve.After it was reduced in flowing N_(2) at 570℃ and appropriate oxygen vacancies were induced,supcrconductivity with T_(c)^(on)=6K was obtained.The great influence of oxygen deficience on 3uperconductivity is evident.Also,the incorporation of Pb adjusted the modulation pattern. | LIU Yongqian HUANG Yuzhen CHEN Liquan CHEN Hong LI Jianqi NI Yongming JIA Shunlian ZHAO Zhongxian | 1990 | Chinese Physics Letters1990，7，11： | 0 |
| 15 | Novel CD-MOF NIR-II fluorophores for gastric ulcer imaging显示文摘Gastric ulcers are one of the most common stomach diseases that often accompanied by inflammation,congestion,edema,scar tissue formation,and pyloric obstruction.Fiberoptic endoscopy and X-ray analysis of the upper GI tract have become the diagnostic procedure of choice for patients.However,conventional diagnosis technology is either invasive or radioactive.Herein,a novel CD-MOF NIR-II fluorophore(GPs-CH1055)was developed.The relative fluorophore intensity was largely consistent at various media and pH buffers,and it can swell into gel particles in solvents and be completely expelled from the gastrointestinal tract without being assimilated.GPs-CH1055 has been further evaluated in vivo,and exhibited strong retention effect on the gastric ulcer sites,bright NIR-II signals with high spatial and temporal resolution.Therefore,GPs-CH1055 shows great promise for realizing real-time gastric ulcer imaging and diagnosis. | Yishen Liu Yuzhen Yuzhen Tian Tian Wumei Wang Jinxia Nong Xue Qiao Fuchun Xu Jianfeng Gao Xuechuan Hong | 2021 | Chinese Chemical Letters2021，32，10： | 0 |
