| 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.

| 3 | Optical vortices 30 years on:OAM manipulation from topological charge to multiple singularities显示文摘Thirty years ago,Coullet et al.proposed that a special optical field exists in laser cavities bearing some analogy with the superfluid vortex.Since then,optical vortices have been widely studied,inspired by the hydrodynamics sharing similar mathematics.Akin to a fluid vortex with a central flow singularity,an optical vortex beam has a phase singularity with a certain topological charge,giving rise to a hollow intensity distribution.Such a beam with helical phase fronts and orbital angular momentum reveals a subtle connection between macroscopic physical optics and microscopic quantum optics.These amazing properties provide a new understanding of a wide range of optical and physical phenomena,including twisting photons,spin–orbital interactions,Bose-Einstein condensates,etc.,while the associated technologies for manipulating optical vortices have become increasingly tunable and flexible.Hitherto,owing to these salient properties and optical manipulation technologies,tunable vortex beams have engendered tremendous advanced applications such as optical tweezers,high-order quantum entanglement,and nonlinear optics.This article reviews the recent progress in tunable vortex technologies along with their advanced applications. | Yijie Shen Xuejiao Wang Zhenwei Xie Changjun Min Xing Fu Qiang Liu Mali Gong Xiaocong Yuan | 2019 | Light(Science & Applications)2019,8,1: | 77 |
| 4 | Reservoir-induced landslides and risk control in Three Gorges Project on Yangtze River,China显示文摘The Three Gorges region in China was basically a geohazard-prone area prior to construction of the Three Gorges Reservoir(TGR).After construction of the TGR,the water level was raised from 70 m to 175 m above sea level(ASL).and annual reservoir regulation has caused a 30-m water level difference after impoundment of the TGR since September 2008.This paper first presents the spatiotemporal distribution of landslides in six periods of 175 m ASL trial impoundments from 2008 to 2014.The results show that the number of landslides sharply decreased from 273 at the initial stage to less than ten at the second stage of impoundment.Based on this,the reservoir-induced landslides in the TGR region can be roughly classified into five failure patterns,i.e.accumulation landslide,dip-slope landslide,reversed bedding landslide,rockfall,and karst breccia landslide.The accumulation landslides and dip-slope landslides account for more than 90%.Taking the Shuping accumulation landslide(a sliding mass volume of 20.7 × 10~6 m^3) in Zigui County and the Outang dip-slope landslide(a sliding mass volume of about 90 × 10~6 m^3) in Fengjie County as two typical cases,the mechanisms of reactivation of the two landslides are analyzed.The monitoring data and factor of safety(FOS) calculation show that the accumulation landslide is dominated by water level variation in the reservoir as most part of the mass body is under 175 m ASL,and the dip-slope landslide is controlled by the coupling effect of reservoir water level variation and precipitation as an extensive recharge area of rainfall from the rear and the front mass is below 175 m ASL.The characteristics of landslide-induced impulsive wave hazards after and before reservoir impoundment are studied,and the probability of occurrence of a landslide-induced impulsive wave hazard has increased in the reservoir region.Simulation results of the Ganjingzi landslide in Wushan County indicate the strong relationship between landslide-induced surge and water variation with high potential risk to shipping and residential areas.Regarding reservoir regulation in TGR when using a single index,i.e.1-d water level variation,water resources are not well utilized,and there is also potential risk of disasters since 2008.In addition,various indices such as 1-d.5-d,and 10-d water level variations are proposed for reservoir regulation.Finally,taking reservoir-induced landslides in June2015 for example,the feasibility of the optimizing indices of water level variations is verified. | Yueping Yin Bolin Huang Wenpei Wang Yunjie Wei Xiaohan Ma Fei Ma Changjun Zhao | 2016 | Journal of Rock Mechanics and Geotechnical Engineering2016,8,5: | 45 |
| 5 | Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings显示文摘Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level. | Ting Lei Meng Zhang Yuru Li Ping Jia Gordon Ning Liu Xiaogeng Xu Zhaohui Li Changjun Min Jiao Lin Changyuan Yu Hanben Niu Xiaocong Yuan | 2015 | Light(Science & Applications)2015,4,1: | 47 |

| 7 | Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China. | Kaiwen Li Tianxin Lin 无 Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang | 2015 | Asian Journal of Urology2015,2,2: | 21 |
| 8 | Formation and destruction processes of upper Sinian oil-gas pools in the Dingshan-Lintanchang structural belt, southeast Sichuan Basin, China显示文摘The lower Cambrian Niutitang Formation hydrocarbon source rocks at the Dingshan-Lintanchang structure in the southeast Sichuan Basin were of medium-good quality with two excellent hydrocarbon-generating centers developed in the periphery areas, with a possibility of forming a medium to large-sized oil-gas field. Good reservoir rocks were the upper Sinian (Dengying Formation) dolomites. The mudstone in the lower Cambrian Niutitang Formation with a good sealing capacity was the cap rock. The widely occurring bitumen in the Dengying Formation indicates that a paleo oil pool was once formed in the study area. The first stage of paleo oil pool formation was maturation of the lower Cambrian source rocks during the late Ordovician. Hydrocarbon generation from the lower Cambrian source rocks stopped due to the Devonian-Carboniferous uplifting. The lower Cambrian source rocks then restarted generation of large quantities of hydrocarbons after deposition of the middle Permian sediments. This was the second stage of the paleo oil pool formation. The oil in the paleo oil pool began to crack during the late Triassic and a paleo gas pool was formed. This paleo gas pool was destroyed during the Yanshan-Himalayan folding, uplifting and denudation. Bitumen can be widely seen in the Dengying Formation in wells and outcrops in the Sichuan Basin and its periphery areas. This provides strong evidence that the Dengying Formation in the Sichuan Basin and its periphery areas was once an ultra-large structural-lithologic oil-gas field, which was damaged during the Yanshan-Himalayan period. | Liu Shugen Zhang Zhijing Huang Wenming Wang Guozhi Sun Wei Xu Guosheng Yuan Haifeng Zhang Changjun Deng Bin | 2010 | Petroleum Science2010,7,3: | 20 |
| 9 | Virus-induced gene silencing and its application in plant functional genomics显示文摘Virus-induced gene silencing is regarded as a powerful and efficient tool for the analysis of gene function in plants because it is simple, rapid and transformation-free. It has been used to perform both forward and reverse genetics to identify plant functional genes. Many viruses have been developed into virus-induced gene silencing vectors and gene functions involved in development, biotic and abiotic stresses, metabolism, and cellular signaling have been reported. In this review, we discuss the development and application of virus-induced gene silencing in plant functional genomics. | HUANG ChangJun QIAN YaJuan LI ZhengHe ZHOU XuePing | 2012 | Science China(Life Sciences)2012,55,2: | 20 |

| 11 | MiR-182 is up-regulated and targeting Cebpa in hepatocellular carcinoma显示文摘MicroRNAs(miRNAs) are endogenous small non-coding RNAs that repress their targets at post transcriptional level.Existing studies have shown that miRNAs are important regulatory genes in hepatocellular carcinoma(HCC),as either tumor suppressors or oncogenes.MiR-122 is normally downregulated in HCC and regarded as a tumor suppressor.Recently miR-122 has been reported to be regulated by CEBPA,which is then involved in a novel pathway to influence proliferation of tumor cells.However it is unknown whether CEBPA is regulated by miRNAs in HCC.In this study,we find that miR-182 is upregulated in HCC model rat,and represses CEBPA in both rat and human.This further improves the current CEBPA/miR-122 pathway that controls the proliferation of tumor cells.These results suggest that miR-182 is a potential oncogene in HCC and could be used as a diagnostic marker and drug target of HCC. | Chenggang Wang Ren Ren Haolin Hu Changjun Tan Miao Han Xiaolin Wang Yun Zheng | 2014 | Chinese Journal of Cancer Research2014,26,1: | 13 |

| 13 | Hydrothermal Dolomite in the Upper Sinian (Upper Proterozoic) Dengying Formation, East Sichuan Basin, China显示文摘Hydrothermal Dolomite(HTD) is present in the Upper Sinian(Upper Proterozoic) Dengying Formation, east Sichuan Basin, China. The strata are comprised by primary dolomite. The HTD has various textures, including zebra dolomite, subhorizontal sheet-like cavities filled by saddle dolomite and breccias cemented by saddle dolomites as well occur as a fill of veins and fractures. Also co-occur MVT type lead-zinc ores in the study area. The δ13C and δ18O isotopes of HTD in the Upper Sinian Dengying Formation are lighter than those of the host rocks, while 87Sr/86 Sr is higher. The apparent difference in carbon, oxygen and strontium isotopes, especially the large difference in 87Sr/86 Sr isotopes ratio indicate crystallization from hot basinal and/or hydrothermal fluids. Saddle dolomite was precipitated at temperatures of 270-320°C. The diagenetic parasequences of mineral assemblage deposited in the Dengying Formation are:(1) dolomite host rock →sphalerite-galena-barite-fluorite;(2) dolomite host rock →saddle dolomite →quartz;(3) dolomite host rock → saddle dolomite→bitumen;(4) dolomite host rock → saddle dolomite → barite. The mean chemical composition of the host dolomite matrix and HTD didn't change much during hydrothermal process. The fluids forming the HTDs in the Dengying Formation were mixtures of freshwater from the unconformity at the top of Sinian, fluids from diagenetic compaction and hydrocarbon generation & expulsion from the Lower Cambrian Niutitang Formation mudstones or the Doushantuo Formation silty mudstones, and hydrothermal fluids from the basement. The hydrocarbon reservoirs associated with the HTD were mostly controlled by the basement faults and fractures and karsting processes at the unconformity separating Sinian and Cambrian strata. The hydrocarbon storage spaces of HTD included dissolved cavities and intercrystalline pores. Dissolution cavities are extensive at the top of Dengying Formation, up to about 46 m below the unconformity between Sinian and Cambrian and were generated mainly during karstification. Hydrothermal alteration enhanced the reservoir property of the Dengying Formation dolomites with 3%-5% increase in porosity. No agreement has been reached why zebra dolomite occurs only in the Upper Sinian strata, which would indicate that HTD mineralization occurred during two different periods, each of them related to major extensional tectonic event. The early one related to the Xingkai taphrogenesis(Z2-?1)and the later one to the Emei taphrogenesis(D2-T2). But, all the data from saddle dolomite suggest that the predominant crystallization occurred during the latter event. | LIU Shugen HUANG Wenming JANSA Luba F.

| 14 | On-chip plasmonic spin-Hall nanograting for simultaneously detecting phase and polarization singularities显示文摘Phase and polarization singularities are important degrees of freedom for electromagnetic field manipulation.Detecting these singularities is essential for modern optics,but it is still a challenge,especially in integrated optical systems.In this paper,we propose an on-chip plasmonic spin-Hall nanograting structure that simultaneously detects both the polarization and phase singularities of the incident cylindrical vortex vector beam(CVVB).The nanograting is symmetry-breaking with different periods for the upper and lower parts,which enables the unidirectional excitation of the surface plasmon polariton depending on the topological charge of the incident optical vortex beam.Additionally,spin-Hall meta-slits are integrated onto the grating so that the structure has a chiral response for polarization detection.We demonstrate theoretically and experimentally that the designed structure fully discriminates both the topological charges and polarization states of the incident beam simultaneously.The proposed structure has great potential in compact integrated photonic circuits. | Fu Feng Guangyuan Si Changjun Min Xiaocong Yuan Michael Somekh | 2020 | Light(Science & Applications)2020,9,1: | 11 |
| 15 | Endocrine role of bone in the regulation of energy metabolism显示文摘Bone mainly functions as a supportive framework for the whole body and is the major regulator of calcium homeostasis and hematopoietic function.Recently,an increasing number of studies have characterized the significance of bone as an endocrine organ,suggesting that bone-derived factors regulate local bone metabolism and metabolic functions.In addition,these factors can regulate global energy homeostasis by altering insulin sensitivity,feeding behavior,and adipocyte commitment.These findings may provide a new pathological mechanism for related metabolic diseases or be used in the diagnosis,treatment,and prevention of metabolic diseases such as osteoporosis,obesity,and diabetes mellitus.In this review,we summarize the regulatory effect of bone and bone-derived factors on energy metabolism and discuss directions for future research. | Ruoyu Zhou Qiaoyue Guo Ye Xiao Qi Guo Yan Huang Changjun Li Xianghang Luo | 2021 | Bone Research2021,9,4: | 11 |
| 16 | An efficient methodology for utilization of K-feldspar and phosphogypsum with reduced energy consumption and CO2 emissions显示文摘The issues of reducing CO_2 emissions, sustainably utilizing natural mineral resources, and dealing with industrial waste offer challenges for sustainable development in energy and the environment. We propose an efficient methodology via the co-reaction of K-feldspar and phosphogypsum for the extraction of soluble potassium salts and recovery of SO_2 with reduced CO_2 emission and energy consumption. The results of characterization and reactivity evaluation indicated that the partial melting of K-feldspar and phosphogypsum in the hightemperature co-reaction significantly facilitated the reduction of phosphogypsum to SO_2 and the exchange of K^+(K-feldspar) with Ca^(2+)(CaSO_4 in phosphogypsum). The reaction parameters were systematically investigated with the highest sulfur recovery ratio of ~ 60% and K extraction ratio of ~ 87.7%. This novel methodology possesses an energy consumption reduction of ~ 28% and CO_2 emission reduction of ~ 55% comparing with the present typical commercial technologies for utilization of K-feldspar and the treatment of phosphogypsum. | Zhixi Gan Zheng Cui Hairong Yue Siyang Tang Changjun Liu Chun Li Bin Liang Heping Xie | 2016 | Chinese Journal of Chemical Engineering2016,24,11: | 11 |

| 18 | Modeling and Robust Backstepping Sliding Mode Control with Adaptive RBFNN for a Novel Coaxial Eight-rotor UAV显示文摘This paper focuses on the robust attitude control of a novel coaxial eight-rotor unmanned aerial vehicles(UAV) which has higher drive capability as well as greater robustness against disturbances than quad-rotor UAV. The dynamical and kinematical model for the coaxial eight-rotor UAV is developed, which has never been proposed before. A robust backstepping sliding mode controller(BSMC) with adaptive radial basis function neural network(RBFNN) is proposed to control the attitude of the eightrotor UAV in the presence of model uncertainties and external disturbances. The combinative method of backstepping control and sliding mode control has improved robustness and simplified design procedure benefiting from the advantages of both controllers. The adaptive RBFNN as the uncertainty observer can effectively estimate the lumped uncertainties without the knowledge of their bounds for the eight-rotor UAV. Additionally, the adaptive learning algorithm, which can learn the parameters of RBFNN online and compensate the approximation error, is derived using Lyapunov stability theorem. And then the uniformly ultimate stability of the eight-rotor system is proved. Finally, simulation results demonstrate the validity of the proposed robust control method adopted in the novel coaxial eight-rotor UAV in the case of model uncertainties and external disturbances. | Cheng Peng Yue Bai Xun Gong Qingjia Gao Changjun Zhao Yantao Tian | 2015 | IEEE/CAA Journal of Automatica Sinica2015,2,1: | 10 |
