| 1 | Laparoscopic Partial Nephrectomy With Segmental Renal Artery Clamping:Technique and Clinical Outcomes显示文摘Background:Warm ischemic injury is one of the most important factors affecting renal function in partial nephrectomy(PN).The technique of segmental renal artery clamping emerges as an alternative to conventional renal artery clamping for renal hilar control.Objective:To evaluate the feasibility and efficiency of laparoscopic PN(LPN) with segmental renal artery clamping in comparison with the conventional technique.Design,setting,and participants:A total of 75 patients underwent LPN from June 2007 to November 2009.All patients had T1a or T1b tumor in one kidney and a normal contralateral kidney.Thirty-seven patients underwent surgeries with main renal artery clamping,and 38 underwent surgeries with segmental artery clamping.Intervention:All procedures were performed by the same laparoscopic surgeon.Measurements:Blood loss,operation time,warm ischemia(WI) time,and complications affected renal function before and after operation were recorded.Results and limitations:All LPNs were completed without conversion to open surgery or nephrectomy.The novel technique slightly increased WI time(p < 0.001) and intraoperative blood loss(p = 0.006),while it provided better postoperative affected renal function(p < 0.001) compared with the conventional technique.The total complication rate was 12%.Among the 38 cases where segmental renal artery clamping was performed,7 had to convert to the conventional method.Tumor size and location influenced the number of clamped segmental arteries.Long-term postoperative renal function is still awaited.Conclusions:LPN with segmental artery clamping is safe and feasible in clinical practice.It minimizes the intraoperative WI injury and improves early postoperative affected renal function compared with main renal artery clamping.(C) 2010 European Association of Urology.Published by Elsevier B.V.All rights reserved. | Shao,P.F.

| 2 | Short-chain fatty acids act as antiinflammatory mediators by regulating prostaglandin E_2 and cytokines显示文摘AIM:To investigate the effect of short-chain fatty ac-ids (SCFAs) on production of prostaglandin E2 (PGE2),cytokines and chemokines in human monocytes.METHODS:Human neutrophils and monocytes were isolated from human whole blood by using 1-Step Polymorph and RosetteSep Human Monocyte Enrich-ment Cocktail,respectively. Human GPR41 and GPR43 mRNA expression was examined by quantitative real-time polymerase chain reaction. The calcium flux assay was used to examine the biological activities of SCFAs in human neutrophils and monocytes. The effect ofSCFAs on human monocytes and peripheral blood mononuclear cells (PBMC) was studied by measuring PGE2,cytokines and chemokines in the supernatant. The effect of SCFAs in vivo was examined by intraplantar injection into rat paws.RESULTS:Human GPR43 is highly expressed in human neutrophils and monocytes. SCFAs induce robust calcium flux in human neutrophils,but not in human monocytes. In this study,we show that SCFAs can in-duce human monocyte release of PGE2 and that this effect can be enhanced in the presence of lipopolysac-charide (LPS). In addition,we demonstrate that PGE2 production induced by SCFA was inhibited by pertussis toxin,suggesting the involvement of a receptor-mediated mechanism. Furthermore,SCFAs can specifi cally inhibit constitutive monocyte chemotactic protein-1 (MCP-1) production and LPS-induced interleukin-10 (IL-10) production in human monocytes without affecting the secretion of other cytokines and chemokines examined. Similar activities were observed in human PBMC for the release of PGE2,MCP-1 and IL-10 after SCFA treatment. In addition,SCFAs inhibit LPS-induced production of tumor necrosis factor-α and interferon-γ in human PBMC. Finally,we show that SCFAs and LPS can induce PGE2 production in vivo by intraplantar injection into rat paws (P < 0.01). CONCLUSION:SCFAs can have distinct antiinflammatory activities due to their regulation of PGE2,cytokine and chemokine release from human immune cells. | Mary Ann Cox James Jackson Michaela Stanton Alberto Rojas-Triana Loretta Bober Maureen Laverty Xiaoxin Yang Feng Zhu Jianjun Liu Suke Wang Frederick Monsma Galya Vassileva Maureen Maguire Eric Gustafson Marvin Bayne Chuan-Chu Chou Daniel Lundell Chung-Her Jenh | 2009 | World Journal of Gastroenterology2009，15，44： | 30 |
| 3 | Aerosol scattering coefficients and major chemical compositions of fine particles observed at a rural site in the central Pearl River Delta,South China显示文摘During November-December 2010 aerosol scattering coefficients were monitored using a single-waved (525 nm) Nephelometer at a regional monitoring station in the central Pearl River Delta region and 24-hr fine particle (PM 2.5) samples were also collected during the period using quartz filters for the analysis of major chemical components including organic carbon (OC),elemental carbon (EC),sulfate,nitrate and ammonium.In average,these five components accounted for about 85% of PM 2.5 mass and contributed 42% (OC),19% (SO 4 2 -),12% (NO 3 -),8.4% (NH 4+) and 3.7% (EC),to PM 2.5 mass.A relatively higher mass scattering efficiency of 5.3 m 2/g was obtained for fine particles based on the linear regression between scattering coefficients and PM 2.5 mass concentrations.Chemical extinction budget based on IMPROVE approach revealed that ammonium sulfate,particulate organic matter,ammonium nitrate and EC in average contributed about 32%,28%,20% and 6% to the light extinction coefficients,respectively. | Xinming Wang Xiang Ding Xiaoxin Fu Quanfu He Shaoyi Wang Francois Bernard Xiuying Zhao Dui Wu | 2012 | Journal of Environmental Sciences2012，24，1： | 25 |
| 4 | On the new results of global attractive set and positive invariant set of the Lorenz chaotic system and the applications to chaos control and synchronization显示文摘Constructing a family of generalized Lyapunov functions, a new method is proposed to obtain new global attractive set and positive invariant set of the Lorenz chaotic system. The method we proposed greatly simplifies the complex proofs of the two famous estimations presented by the Russian scholar Leonov. Our uniform formula can derive a series of the new estimations. Employing the idea of intersection in set theory, we extract a new Leonov formula-like estimation from the family of the estimations. With our method and the new estimation, one can confirm that there are no equilibrium, periodic solutions, almost periodic motions, wandering motions or other chaotic attractors outside the global attractive set. The Lorenz butterfly-like singular attractors are located in the global attractive set only. This result is applied to the chaos control and chaos synchronization. Some feedback control laws are obtained to guarantee that all the trajectories of the Lorenz systems track a periodic solution, or globally stabilize an unstable (or locally stable but not globally asymptotically stable) equilibrium. Further, some new global exponential chaos synchronization results are presented. Our new method and the new results are expected to be applied in real secure communication systems. | LIAO Xiaoxin 1, 2, 3 , FU Yuli 4 & XIE Shengli 4 1.

| 6 | Future extreme climate changes linked to global warming intensity显示文摘Based on the Coupled Model Intercomparison Project Phase 5(CMIP5) daily dataset, we investigate changes of the terrestrial extreme climates given that the global mean temperature increases persistently under the Representative Concentration Pathways 8.5(RCP8.5) scenario. Compared to preindustrial conditions, more statistically significant extreme temperatures, precipitations, and dry spells are expected in the 21 st century. Cold extremes decrease and warm extremes increase in a warmer world, and cold extremes tend to be more sensitive to global warming than the warm ones. When the global mean temperature increases, cold nights, cold days, and warm nights all display nonlinear relationships with it,such as the weakening of the link projected after 3 °C global warming, while the other indices generally exhibit differently, with linear relationships. Additionally, the relative changes in the indices related to extreme precipitation show significantly consistent linear changes with the global warming magnitude.Compared with the precipitation extremes, changes in temperature extremes are more strongly related to the global mean temperature changes. For the projection of the extreme precipitation changes, models show higher uncertainty than that in extreme temperature changes, and the uncertainty for the precipitation extremes becomes more remarkable when the global warming exceeds 5 °C. | Xiaoxin Wang Dabang Jiang Xianmei Lang | 2017 | Science Bulletin2017，62，24： | 20 |
| 7 | Changes in visibility with PM_(2.5) composition and relative humidity at a background site in the Pearl River Delta region显示文摘In fall–winter, 2007–2013, visibility and light scattering coefficients(b sp) were measured along with PM_(2.5)mass concentrations and chemical compositions at a background site in the Pearl River Delta(PRD) region. The daily average visibility increased significantly(p < 0.01) at a rate of 1.1 km/year, yet its median stabilized at ~13 km. No haze days occurred when the 24-hr mean PM_(2.5)mass concentration was below 75 μg/m^3. By multiple linear regression on the chemical budget of particle scattering coefficient(b sp), we obtained site-specific mass scattering efficiency(MSE) values of 6.5 ± 0.2, 2.6 ± 0.3, 2.4 ± 0.7 and 7.3 ± 1.2 m2/g,respectively, for organic matter(OM), ammonium sulfate(AS), ammonium nitrate(AN) and sea salt(SS). The reconstructed light extinction coefficient(b ext) based on the Interagency Monitoring of Protected Visual Environments(IMPROVE) algorithm with our site-specific MSE revealed that OM, AS, AN, SS and light-absorbing carbon(LAC) on average contributed 45.9% ± 1.6%,25.6% ± 1.2%, 12.0% ± 0.7%, 11.2% ± 0.9% and 5.4% ± 0.3% to light extinction, respectively.Averaged b ext displayed a significant reduction rate of 14.1/Mm·year(p < 0.05); this rate would be 82% higher if it were not counteracted by increasing relative humidity(RH) and hygroscopic growth factor(f(RH)) at rates of 2.5% and 0.16/year-1(p < 0.01), respectively, during the fall–winter, 2007–2013. This growth of RH and f(RH) partly offsets the positive effects of lowered AS in improving visibility, and aggravated the negative effects of increasing AN to impair visibility. | Xiaoxin Fu Xinming Wang Qihou Hu Guanghui Li Xiang Ding Yanli Zhang Quanfu He Tengyu Liu Zhou Zhang Qingqing Yu Ruqing Shen Xinhui Bi | 2016 | Journal of Environmental Sciences2016，28，2： | 18 |
| 8 | Knowledge Model for Electric Power Big Data Based on Ontology and Semantic Web显示文摘It is very important for the development of electric power big data technology to use the electric power knowledge.A new electric power knowledge theory model is proposed here to solve the problem of normalized modeled electric power knowledge for the management and analysis of electric power big data.Current modeling techniques of electric power knowledge are viewed as inadequate because of the complexity and variety of the relationships among electric power system data.Ontology theory and semantic web technologies used in electric power systems and in many other industry domains provide a new kind of knowledge modeling method.Based on this,this paper proposes the structure,elements,basic calculations and multidimensional reasoning method of the new knowledge model.A modeling example of the regulations defined in electric power system operation standard is demonstrated.Different forms of the model and related technologies are also introduced,including electric power system standard modeling,multi-type data management,unstructured data searching,knowledge display and data analysis based on semantic expansion and reduction.Research shows that the new model developed here is powerful and can adapt to various knowledge expression requirements of electric power big data.With the development of electric power big data technology,it is expected that the knowledge model will be improved and will be used in more applications. | Yanhao Huang Xiaoxin Zhou | 2015 | CSEE Journal of Power and Energy Systems2015，1，1： | 17 |
| 9 | A DC Grid Benchmark Model for Studies of Interconnection of Power Systems显示文摘Reducing carbon emissions in the power sector is critical for transitioning to a sustainable and low-carbon future.Estimating carbon efficiency of demand side response(DSR)in the power system is an important step towards realizing potential environmental benefits.Marginal emission factor(MEF)is an effective tool for estimating incremental changes in carbon emissions as a result of a change in demand.However,estimation methods currently used for evaluating MEF can be improved upon,specifically,by factoring in the ramp-rate constraint of generators in the fuel cost based merit order dispatch.In this paper is described a new method for MEF assessment under ramp-rate constraints;the method is then compared with two conventional estimations in a British power system.Three fuel price scenarios are used to conduct a sensitivity analysis of MEFs to fuel prices.Conclusions are drawn that can pave the way for future improvements in estimating MEF in power systems. | Ting An Xiaoxin Zhou Congda Han Yanan Wu Zhiyuan He Hui Pang Guangfu Tang | 2015 | CSEE Journal of Power and Energy Systems2015，1，4： | 17 |
| 10 | Ionic composition of submicron particles(PM_(1.0)) during the long-lasting haze period in January 2013 in Wuhan, central China显示文摘In January 2013, a long-lasting severe haze episode occurred in Northern and Central China; at its maximum, it covered a land area of approximately 1.4 million km2. In Wuhan, the largest city in Central China, this event was the most severe haze episode in the 21st century. Aerosol samples of submicron particles(PM1.0) were collected during the long-lasting haze episode at an urban site and a suburban site in Wuhan to investigate the ion characteristics of PM1.0 in this area. The mass concentrations of PM1.0 and its water-soluble inorganic ions(WSIIs) were almost at the same levels at two sites, which indicates that PM1.0 pollution occurs on a regional scale in Wuhan. WSIIs(Na+, NH+ 4, K+, Mg2+, Ca2+, Cl-, NO-3and SO2-4) were the dominant chemical species and constituted up to 48.4% and 47.4% of PM1.0 at WD and TH, respectively. The concentrations of PM1.0 and WSIIs on haze days were approximately two times higher than on normal days. The ion balance calculations indicate that the particles were more acidic on haze days than on normal days. The results of the back trajectory analysis imply that the high concentrations of PM1.0 and its water-soluble inorganic ions may be caused by stagnant weather conditions in Wuhan. | Hairong Cheng Wei Gong Zuwu Wang Fan Zhang Xinming Wang Xiaopu Lv Jia Liu Xiaoxin Fu Gan Zhang | 2014 | Journal of Environmental Sciences2014，26，4： | 15 |
| 11 | Research progress on human infection with avian influenza H7N9显示文摘Since the first case of novel H7N9 infection was reported,China has experienced five epidemics of H7N9.During the fifth wave,a highly pathogenic H7N9 strain emerged.Meanwhile,the H7N9 virus continues to accumulate mutations,and its affinity for the human respiratory epithelial sialic acid 2-6 receptor has increased.Therefore,a pandemic is still possible.In the past 6 years,we have accumulated rich experience in dealing with H7N9,especially in terms of virus tracing,epidemiological research,key site mutation monitoring,critical disease mechanisms,clinical treatment,and vaccine development.In the research fields above,significant progress has been made to effectively control the spread of the epidemic and reduce the fatality rate.To fully document the research progress concerning H7N9,we reviewed the clinical and epidemiological characteristics of H7N9,the key gene mutations of the virus,and H7N9 vaccine,thus providing a scientific basis for further monitoring and prevention of H7N9 influenza epidemics. | Xiaoxin Wu Lanlan Xiao Lanjuan Li | 2020 | Frontiers of Medicine2020，14，1： | 14 |
| 12 | Study of altitudinal lapse rates of δ^(18)O in precipitation/river water with seasons on the southeast Tibetan Plateau显示文摘Seasonal δ 18O variation in water on the southeast Tibetan Plateau has been studied, showing the consistent variation pattern of δ 18O with altitude indicative of relevant atmospheric circulation processes. Study shows a similar variation pattern of fixed-site river water δ 18O with that of the precipitation δ 18O in southeast Tibet. δ 18O in regional rivers in southeast Tibet demonstrates a gradual depletion with increasing altitude, though the rates vary seasonally. The most depleted river 18O occurs during the monsoon period, with the lowest δ 18O/altitude lapse rate. The river 18O during the westerly period is also depleted, together with low δ 18O/altitude lapse rate. The pre-monsoon rivers witness the most enriched 18O with least significant correlation coefficient with the linear regression, whilst the postmonsoon rivers witness the largest δ 18O/altitude lapse rate. Different coherence of seasonal δ 18O variation with the altitude effect is attributed to different moisture supplies. Though sampling numbers vary with seasons, the δ 18O-H linear correlation coefficients all reach the 0.05 confidence level, thus witnessing the variation features of δ 18O in seasonal river water due to the influence of atmospheric general circulation and land surface processes revealed from the altitudinal lapse rates. | YANG XiaoXin XU BaiQing YANG Wei QU DongMei LIN Ping-Nan | 2009 | Chinese Science Bulletin2009，54，16： | 13 |
| 13 | Cotton-derived oxygen/sulfur co-doped hard carbon as advanced anode material for potassium-ion batteries显示文摘Hard carbon is regarded as promising anode materials for potassium-ion batteries(KIBs)owing to their low price and easy availability.However,the limited rate capability still needs to be improved.Herein,we demonstrate the fabrication of oxygen/sulfur co-doped hard carbon through a facile hydrolyzationsulfuration process of skimmed cotton.The simultaneous dopants significantly improve potassium ion diffusion rate.When served as the anode for KIBs,this hydrolyzed hard carbon delivered a high reversible capacity(409 mAh/g at 0.1 A/g),superior rate capability(135 mAh/g at 2 A/g)and excellent cyclability(about 120 mAh/g overt 500 cycles at 2 A/g).This work provides a facile strategy to prepare low-cost doped-hard carbon with superior potassium storage property. | Baolin Xu Shihan Qi Fang Li Xiaoxin Peng Jinfeng Cai Jiaojiao Liang Jianmin Ma | 2020 | Chinese Chemical Letters2020，31，1： | 12 |

| 17 | Analysis of Low Frequency Oscillation and Source Location in Power Systems显示文摘The major problem in current online diagnosis and analysis for power system oscillation is mainly concerned with finding the oscillation source in a fast and correct way using the data collected by the Wide Area Measurement System(WAMS).This paper for the first time proposes a scheme of cut set energy based on WAMS.Independent of accurate parameters,the scheme can make full use of WAMS data based on cut set energy construction and fast calculation to locate the source during oscillation.Afterwards,a scheme of torque decomposition is proposed,based on which the controller’s torque can be divided into damping torque and synchronous torque by calculation through WAMS data,and this paper puts forward the abnormal response and simulation models calibration of influential controllers.Analysis of an oscillation case shows how the cut set energy scheme and the torque decomposition scheme are applied in a real-world power system,and the schemes are proven to be reliable and practical in identifying and locating oscillation sources. | Yinbiao Shu Xiaoxin Zhou Wenfeng Li | 2018 | CSEE Journal of Power and Energy Systems2018，4，1： | 11 |
| 18 | Personalized targeted therapy for esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma continues to heavily burden clinicians worldwide. Researchers have discovered the genomic landscape of esophageal squamous cell carcinoma, which holds promise for an era of personalized oncology care. One of the most pressing problems facing this issue is to improve the understanding of the newly available genomic data, and identify the driver-gene mutations, pathways, and networks. The emergence of a legion of novel targeted agents has generated much hope and hype regarding more potent treatment regimens, but the accuracy of drug selection is still arguable. Other problems, such as cancer heterogeneity, drug resistance, exceptional responders, and side effects, have to be surmounted. Evolving topics in personalized oncology, such as interpretation of genomics data, issues in targeted therapy, research approaches for targeted therapy, and future perspectives, will be discussed in this editorial. | Xiaozheng Kang Keneng Chen Yicheng Li Jianying Li Thomas A D'Amico Xiaoxin Chen | 2015 | World Journal of Gastroenterology2015，21，25： | 10 |
