1NEW METHOD OF SIMULATING CONCENTRATED DRAIN HOLES IN SEEPAGE CONTROL ANALYSIS显示文摘In this paper, based upon the basic solution of sink, the approximate solution of single drain hole in finite elements is derived by use of the superposition principle. Then, the theoretical solution is extended to the case of some drain holes in one finite element, and the method is used in seepage control analysis with quick convergence and high accuracy. On the other hand, if the positions of the drain holes are changed, only some control factors of drain holes are changed, but the finite element grid need not to be reformed. Therefore, the method is more suitable in optimal research of seepage control.Zhan Mei li, Su Bao yu , Liu Jun yong, Shen Zhen zhong College of Water Conservancy and Hydropower Engineering, Hohai University, Nanjing 210098, P.R.China (Received Aug.1, 1998) 1999Journal of Hydrodynamics1999,11,3:22

3Ni/Al_2O_3 catalysts for CO methanation: Effect of Al_2O_3 supports calcined at different temperatures显示文摘The correlation between phase structures and surface acidity of Al2O3 supports calcined at different temperatures and the catalytic performance of Ni/Al2O3 catalysts in the production of synthetic natural gas(SNG) via CO methanation was systematically investigated. A series of 10 wt% NiO/Al2O3 catalysts were prepared by the conventional impregnation method, and the phase structures and surface acidity of Al2O3 supports were adjusted by calcining the commercial γ-Al2O3 at different temperatures(600–1200 C). CO methanation reaction was carried out in the temperature range of 300–600 C at different weight hourly space velocities(WHSV = 30000 and 120000 mL·g-1h-1) and pressures(0.1 and 3.0 MPa). It was found that high calcination temperature not only led to the growth in Ni particle size, but also weakened the interaction between Ni nanoparticles and Al2O3 supports due to the rapid decrease of the specific surface area and acidity of Al2O3 supports. Interestingly, Ni catalysts supported on Al2O3 calcined at 1200 C(Ni/Al2O3-1200) exhibited the best catalytic activity for CO methanation under different reaction conditions. Lifetime reaction tests also indicated that Ni/Al2O3-1200 was the most active and stable catalyst compared with the other three catalysts, whose supports were calcined at lower temperatures(600, 800 and 1000 C). These findings would therefore be helpful to develop Ni/Al2O3 methanation catalyst for SNG production.Jiajian Gao Chunmiao Jia Jing Li Meiju Zhang Fangna Gu Guangwen Xu Ziyi Zhong Fabing Su 2013Journal of Energy Chemistry2013,22,6:16

6Complement C3 activation regulates the production of tRNA-derived fragments Gly-tRFs and promotes alcohol-induced liver injury and steatosis显示文摘Complement is known to play a role in alcoholic fatty liver disease (AFLD), but the underlying mechanisms are poorly understood, thereby constraining the development of a rational approach for therapeutic intervention in the complement system. C3 deficiency has been shown to impart protective effects against ethanol-induced hepatic steatosis and inflammation. Here we demonstrate a protection effect in wild-type mice by treatment with CR2-Crry, a specific inhibitor of C3 activation. The expression of glycine transfer (t) RNA-derived fragments (Gly-tRFs) is upregulated in ethanol-fed mice and inhibition of Gly-tRFs in vivo decreases chronic ethanol feeding-induced hepatosteatosis without affecting inflammation. The expression of Gly-tRF was downregulated in C3-deficient or CR2-Crry-treated mice, but not in C5-deficient mice;Gly-tRF expression was restored by the C3 activation products C3a or Asp (C3a-des-Arg) via the regulation of CYP2E1. Transcriptome profiling of hepatic tissues showed that Gly-tRF inhibitors upregulate the expression of sirtuin1 (Sirt1) and subsequently affect downstream lipogenesis and β-oxidation pathways. Mechanistically, Gly-tRF interacts with AGO3 to downregulate Sirt1 expression via sequence complementarity in the 3′ UTR. Notably, the expression levels of C3d, CYP2E1 and Gly-tRF are upregulated, whereas Sirt1 is decreased in AFLD patients compared to healthy controls. Collectively, our findings suggest that C3 activation products contribute to hepatosteatosis by regulating the expression of Gly-tRF. Complement inhibition at the C3 activation step and treatment with Gly-tRF inhibitors may be potential and precise therapeutic approaches for AFLD.Fudi Zhong Zhigao Hu Keqing Jiang Biao Lei Zhan Wu Guandou Yuan Hongliang Luo Chunqiang Dong Bo Tang Chaowen Zheng Shuai Yang Yonglian Zeng Zhenya Guo Shuiping Yu Huizhao Su Guo Zhang Xiaoqiang Qiu Stephen Tomlinson Songqing He 2019Cell Research2019,29,7:14
7γ-MnO2 nanorods/graphene composite as efficient cathode for advanced rechargeable aqueous zinc-ion battery显示文摘Aqueous Zn//MnO2 batteries are emerging as promising large-scale energy storage devices owing to their cost-effectiveness,high safety,high output voltage,and energy density.However,the MnO2 cathode suffers from intrinsically poor rate performance and rapid capacity deterioration.Here,we remove the roadblock by compositing MnO2 nanorods with highly conductive graphene,which remarkably enhances the electrochemical properties of the MnO2 cathode.Benefiting from the boosted electric conductivity and ion diffusion rate as well as the structural protection of graphene,the Zn//MnO2-graphene battery presents an admirable capacity of 301 mAh g^-1 at 0.5 A g^-1,corresponding to a high energy density of 411.6 Wh kg^-1.Even at a high current density of 10 A g^-1,a decent capacity of 95.8 mAh g^-1 is still obtained,manifesting its excellent rate property.Furthermore,an impressive power density of 15 kW kg^-1 is achieved by the Zn//MnO2-graphene battery.Chao Wang Yinxiang Zeng Xiang Xiao Shijia Wu Guobin Zhong Kaiqi Xu Zengfu Wei Wei Su Xihong Lu 2020Journal of Energy Chemistry2020,29,4:13
8Microvascular changes after conbercept therapy in central retinal vein occlusion analyzed by optical coherence tomography angiography显示文摘AIM: To investigate microvascular changes in eyes with central retinal vein occlusion(CRVO) complicated by macular edema before and after intravitreal conbercept injection and evaluate correlations between these changes and best-corrected visual acuity(BCVA) and retinal thickness. METHODS: Twenty-eight eyes of 28 patients with macular edema caused by CRVO were included in this retrospective study. All patients received a single intravitreal conbercept injection to treat macular edema. BCVA and the results of optical coherence tomography angiography(OCTA) automatic measurements of the vessel density in the superficial(SCP) and deep retinal capillary plexus(DCP), the foveal avascular zone(FAZ) area, the FAZ perimeter(PERIM), the vessel density within a 300-μm wide ring surrounding the FAZ(FD-300), the acircularity index(AI), the choriocapillaris flow area, and retinal thickness were recorded before and at one month after treatment and compared with the results observed in age-and sexmatched healthy subjects. RESULTS: The vessel density in the SCP and DCP, the FD-300, and the flow area of the choriocapillaris were allsignificantly lower in CRVO eyes than in healthy eyes, while the AI and retinal thickness were significantly higher(all P<0.05). After treatment, retinal thickness was significantly decreased, and the mean BCVA had markedly improved from 20/167 to 20/65(P=0.0092). The flow area of the choriocapillaris was also significantly improved, which may result from the reduction of shadowing effect caused by the attenuation of macular edema. However, there were no significant changes in SCP and DCP vessel density after treatment. The flow area of the choriocapillaris at baseline was negatively correlated with retinal thickness.CONCLUSION: OCTA enables the non-invasive, layerspecific and quantitative assessment of microvascular changes both before and after treatment, and can therefore be used as a valuable imaging tool for the evaluation of the follow-up in CRVO patients.Yang Deng Qi-Wen Zhong Ai-Qi Zhang Xiao-Juan Cai Ming-Zhi Lu Shao-Chong Zhang Li-Shi Su Hui Chen Ying Lin Li-Mei Sun Guan-Di Chen Li-Ting Zhong Chen-Jin Jin Wei Chi 2019International Journal of Ophthalmology(English edition)2019,12,5:13
9The Development of A Fluorescence Polarization Immunoassay for Aflatoxin Detection显示文摘A fluorescence polarization immunoassay(FPIA)was developed for the analysis ofaflatoxins(AFs)using an anti-aflatoxin B1(AFB1)monoclonal antibody and a novel fluorescein-labeled AFB1tracer.The FPIA showed an IC50 value of 23.33ng/mL with a limit of detection of 13.12 ng/mL for AFB1.The cross-reactivities of AFB1,AFB2,AFG1,AFG2,AFM1,and AFM2 with the antibody were100%,65.7%,143%,23.5%,111.4%,and 2%,respectively.The group-specificity of anti-AFB1mAb indicated that the FPIA could potentially be used in a screening method for the detection of total AFs,albeit not AFG2 and AFM2.The total time required for analyzing 96 samples in one microplate was less than 5 min.This study demonstrates the potential usefulness of the FPIA as a rapid and simple technique for monitoring AFs.SHENG Ya Jie EREMIN Sergei MI Tie Jun ZHANG Su Xia SHEN Jian Zhong WANG Zhan Hui 2014Biomedical and Environmental Sciences2014,27,2:10

14Antinociceptive effect of berberine on visceral hypersensitivity in rats显示文摘AIM: To assess the protective effect of berberine administration and the role of nitric oxide (NO) in visceral hypersensitivity. METHODS: Fifty male Sprague-Dawley rats were randomly assigned to five groups. An inflammatory bowel disease model was induced in rats by intracolonic instillation of 1 mL 4% acetic acid at 8 cm proximal to the anus for 30 s and restraint stress. After subsidence of inflammation on day 7 of the experiment, the rats were subjected to rectal distension, performed by a balloon (6-Fr, 2 mm external diameter, disposable silicon balloon-urethral catheter for pediatric use) which was rapidly inflated with increasing volumes of prewarmed (37 ℃) water (0.1, 0.2, 0.3, 0.4, 0.6, 0.8 and 1 mL) for 30 s at four-minute intervals, and then the abdominal withdrawal reflex (AWR) and the level of fecal output were measured, respectively. AWR scores either 0, 1, 2, 3 or 4 were obtained by blinded observers. Rats had been pretreated with berberine or aminoguanidine (NO synthetase inhibitor) or berberine + aminoguanidine before measurement. RESULTS: The rats in the placebo group showed a hypersensitive response to rectal distension (2.69 ± 0.08 vs 1.52 ± 0.08, P = 0.000) and defecated more frequently than those in the control group (5.0 ± 0.16 vs 0.44 ± 0.16, P = 0.000). Comparing the berberine with placebo group, the AWR scores were reduced for all distension volumes and were significant at 0.2-1 mL (1.90 ± 0.08 vs 2.69 ± 0.08, P = 0.000), while the numbers of hard pellets, soft pellets, formless stools, and total fecal output in the placebo group were significantly larger than in the berberine group (5.0 ± 0.16 vs 2.56 ± 0.16, P = 0.000). Administration of aminoguanidine or berberine + aminoguanidine before VH score measurement reversed the antinociceptive effect of berberine (2.52 ± 0.08 vs 1.90 ± 0.08, P = 0.000; 2.50 ± 0.08 vs 1.90 ± 0.08, P = 0.000). The numbers of hard pellets, soft pellets, formless stool, and total of fecal output in aminoguanidine group were significantly larger than the corresponding values in control group, berberine group, and berberine + aminoguanidine group (4.81 ± 0.16 vs 0.44 ± 0.16, P = 0.000; 4.81 ± 0.16 vs 2.56 ± 0.16, P = 0.000; 4.81 ± 0.16 vs 3.75 ± 0.16, P = 0.000). The berberine and berberine + aminoguanidine groups showed reduced defecation, but aminoguanidine alone did not reduce defecation (2.56 ± 0.16 vs 4.81 ± 0.16, P = 0.000; 3.75 ± 0.16 vs 4.81 ± 0.16, P = 0.000). CONCLUSION: Berberine had an antinociceptive effect on visceral hypersensitivity, and NO might play a role in this effect.Qing-Lin Tang Min-Ling Lai Yuan-Fu Zhong Ai-Min Wang Jun-Kai Su Ming-Qing Zhang 2013World Journal of Gastroenterology2013,19,28:9
15Strengths, weaknesses, opportunities and threats (SWOT) analysis of reinitiation into methamphetamine abusers: qualitative findings from an exploration of methamphetamine abusers in Shanghai, China显示文摘Background Despite high relapse rate among methamphetamine (MA) abusers, there still have been little empirical data to date detecting the risk factors related to craving and relapse from the perspective of MA abusers. Therefore, the aim of this study was to use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors that could facilitate or impede individuals' abstinence in a real-life context from the perspectives of MA abusers. Aim To use qualitative research methods exploring the strengths, weaknesses, opportunities and threat factors relating to individuals' abstinence in a real-life context. Method Semistructured interviews were conducted with 32 MA abusers recruited in Shanghai guided by open-ended questions on narrating the real-life catalysts and inhibitors related to craving, initiation, relapse and abstinence. All data were transcribed verbatim and analysed using a strengths, weaknesses, opportunities and threats (SWOT) analysis. Results The results of the SWOT analysis revealed that contextual factors including peer influence, prevalence and availability of MA, familiar venue of MA use, discrimination, sexual behaviours, alcohol, emotional states and their attitudes towards smoking MA were important factors that contribute to reinitiation and relapse. Surveillance systems, antidrug social workers, vocational skills trainings, moving to another city and family responsibility might serve as counter measures targeti叩 those mentioned weaknesses and threats above. Conclusion This SWOT analysis highlights the complex nature of relapse. Comprehensive interventions strengtheni叩 coping skills such as virtual reality techniques are desperately needed to facilitate individuals1 sustained abstinence.Youwei Zhu Na Zhong Hang Su Xiaolu Ruan Jiayi Bao Lei Zhang Jiang Du Ding Xu Rongjie Ding Ke Xiao Min Zhao 2019General Psychiatry2019,32,3:9
16Diagnostic and prognostic value of lnc RNA cancer susceptibility candidate 9 in hepatocellular carcinoma显示文摘BACKGROUND Hepatocellular carcinoma(HCC)is a common malignant gastrointestinal tumor.There are currently few clinical diagnostic and prognostic markers for HCC.LncRNA cancer susceptibility candidate 9(CASC9)is a long-chain non-coding RNA discovered in recent years,and previous studies have found that lncRNA CASC9 participates in the occurrence and development of HCC,but its clinical value remains unclear.AIM To determine the expression of lncRNA CASC9 in HCC and its diagnostic and prognostic value.METHODS Data on CASC9 expression in patients with HCC were collected from the Cancer Genome Atlas(TCGA)database to analyze the relationship between CASC9 and patient survival.A total of 80 HCC patients treated in The First Affiliated Hospital of Guangxi Medical University from May 2012 to January 2014 were enrolled in the patient group,and 50 healthy subjects were enrolled in the control group during the same period.CASC9 expression in the two groups was determined using quantitative real-time polymerase chain reaction,and its diagnostic and prognostic value was analyzed based on the CASC9 data and pathological data in these HCC patients.The relationship between CASC9 and patient survival was assessed during the 5-year follow-up period.RESULTS Analysis of data from TCGA database revealed that control samples showed significantly lower CASC9 expression than carcinoma tissue samples(P<0.001);the low CASC9 expression group had a higher survival rate than the high CASC9 expression group(P=0.011),and the patient group showed significantly increased expression of serum CASC9,with the area under the curve(AUC)of 0.933.CASC9 expression was related to tumor size,combined hepatitis,tumor,node,metastasis(TNM)staging,lymph node metastasis,differentiation and alpha fetoprotein,and the high CASC9 expression group showed lower 1-year,3-year and 5-year survival rates than the low CASC9 expression group(all aP<0.05).Multivariate Cox regression analysis revealed that TNM staging,lymph node metastasis,differentiation,alpha fetoprotein and CASC9 were independent factors affecting the prognosis of patients.Stage I+II patients with lymph node metastasis,low differentiation,and alpha fetoprotein>200 ng/mL had a poor 5-year survival rate.CONCLUSION High CASC9 expression is beneficial in the prognosis of HCC patients.CASC9 is expected to be a potential diagnostic and prognostic indicator of HCC.Yong-Lian Zeng Zhen-Ya Guo Hui-Zhao Su Fu-Di Zhong Ke-Qing Jiang Guan-Dou Yuan 2019World Journal of Gastroenterology2019,25,48:9
17GIS-Based Risk Assessment of Debris Flow Disasters in the Upper Reach of Yangtze River显示文摘This paper discussed theory and methodologies of debris-flow risk assessment and established an implementation process according to indicators of debris-flow hazard degree,vulnerability,risk degree,etc. Among these methodologies,historical and potential hazard degree was comprehensively considered into hazard assessment and hazard index was presented to indicate the debris-flow hazard degree. Regarding debris-flow vulnerability assessment,its statistical data and calculating procedure were based on the hazard-degree regionalization instead of administrative divisions,which improved the as-sessing scientificity and precision. These quantitative methodologies inte-grated with Geography Information System(GIS) were applied to the risk assessment of debris flows in the upper reach of Yangtze River. Its results were in substantial agreement on investigation data and the actual distribution of debris flows,which showed that these principles and methodologies were reasonable and feasible and can provide basis or reference for debris-flow risk assessment and disaster management.HAN Yongshun LIU Hongjiang ZHONG Dunlun SU Fenghuan LI Chaokui 2007Wuhan University Journal of Natural Sciences2007,12,4:9

19Isolation,Characterization,and Phylogenetic Analysis of Two New Crimean-Congo Hemorrhagic Fever Virus Strains from the Northern Region of Xinjiang Province,China显示文摘Crimean-Congo hemorrhagic fever(CCHF)caused by the CCHF virus(CCHFV)is a tick-borne natural focal disease with a mortality rate of approximately 50%.CCHFV is widely prevalent in Africa,southern Asia,the Middle East,and southeast Europe.CCHF outbreaks have been reported previously in Xinjiang province,China,especially in its southern region.Epidemiological surveys conducted on ticks and animals have revealed the presence of CCHFV strains in ticks,rodents,and infected individuals from cities and counties in southern Xinjiang.Phylogenetic analyses revealed that the Chinese CCHFV strains belong to one genotype,based on complete sequences of the S segments of its negative-stranded RNA genome.The present study reports two new CCHFV strains isolated from Hyalomma asiaticum asiaticum ticks collected from Fukang City and Wujiaqu City in the northern region of Xinjiang.Viral characteristics and their evolutionary relationships were analyzed through metagenomic and reverse-transcription PCR analyses;these analyses indicated that the genotype of both strains was different from that of other Chinese strains.Furthermore,previous reports of CCHFV in Xinjiang were reviewed and phylogenetic analyses were performed.CCHFV was found to prevail in Fukang City in Junggar Basin for more than 20 years,and that Fukang City and Wujiaqu City are considered natural reservoirs of different genotypes of CCHFV strains.Our findings facilitate the understanding of CCHFV distribution in Xinjiang province and provide insights into the evolutionary relationships among Chinese CCHFV strains.Yanfang Zhang Shu Shen Yaohui Fang Jinliang Liu Zhengyuan Su Jinhao Liang Zhong Zhang Qiaoli Wu Cheng Wang Abulikemu Abudurexiti Zhihong Hu Yujiang Zhang Fei Deng 2018Virologica Sinica2018,33,1:8
20Magnetic properties and large magnetocaloric effects in amorphous Gd-Al-Fe alloys for magnetic refrigeration显示文摘A series of the amorphous Gd75-55Al25-5Fe0-40 alloy ribbons were prepared by melt spinning.The structure,magnetic properties and magnetocaloric effect(MCE) of these alloys were investigated.The prepared samples have shown the characteristics of a second-order phase transition with zero hysteresis loss and the Tc can be tuned by changing the Fe contents.For the different compositions,the magnetic entropy change(--Sm) for a field change of 0-5 T reached a maximum value of 7.14 J kg-1 K-1 in the Gd70Al20Fe10 alloy near its Curie temperature(Tc) of 149 K.The non-linear composition dependence of(-ΔSm) could be caused by the competitions between Fe-Fe,Fe-Gd and Gd-Gd interactions.The refrigeration capacity(RC) values of these alloys are about 532-780 J/kg under a magnetic field change of 0-5 T.The results indicate that amorphous GdFeAl alloys can be considered as ideal candidates for a magnetic refrigerant in the temperature range of 104-222 K.ZHENG ZhiGang ZHONG XiChun SU KunPeng YU HongYa LIU ZhongWu ZENG DeCheng 2011Science China(Physics,Mechanics & Astronomy)2011,54,7:8
