| 1 | Natural orifice transluminal endoscopic surgery in urology: The Chinese experience显示文摘Objective:To describe the Chinese experience of natural orifice transluminal endoscopic surgery(NOTES)in urology.Methods:From December 2008 to May 2017,35 animal experiments and 305 clinical surgeries of NOTES or natural orifices specimen extractions(NOSE)were performed in China.The animal experiments included five kidney biopsies,24 nephrectomies and six partial nephrectomies.The clinical surgeries included 12 transvaginal NOSE(TV-NOSE),266 hybrid transvaginal NOTES(TV-NOTES)and 27 pure TV-NOTES.The TV-NOSE procedure was performed in five transumbilical laparoendoscopic single-site(U-LESS)nephrectomies,four suprapubic-assisted laparoendoscopic single-site surgery(SA-LESS)nephroureterectomies,and three laparoscopic radical cystectomies.The hybrid TV-NOTES procedure included 210 nephrectomies,31 adrenalectomies,eight nephroureterectomies,13 partial nephrectomies,and four heminephrectomies.The pure TV-NOTES procedure included five renal cyst decortications and 22 nephrectomies.Results:A total of 29 animal experiments were successfully performed.One partial nephrectomy was converted to standard laparoscopic surgery.Two kidney biopsies and two nephrectomies were unsuccessful.A total of 297 clinical surgeries were successfully performed.Six patients who underwent hybrid TV-NOTES were converted to open surgery.Two patients who underwent pure TV-NOTES were converted to SA-LESS.There were 22 major complications,16 occurred intraoperatively and six postoperatively.The mean visual analog score(VAS)of 48 h after the operation was 2.5 points in TV-NOSE,2.3 points in hybrid TV-NOTES and 1.7 points in pure TV-NOTES.The mean follow-up of 50.6(3.0-87.0)months showed that all patients were in good condition.The umbilicus scars were nearly invisible in TV-NOSE and hybrid TV-NOTES.The vaginal incision healed well.Conclusions:TV-NOSE and TV-NOTES are feasible,safe,and effective with little injury,low pain,fast recovery,and good cosmetic outcomes in properly selected patients.They are worth consideration for urological clinical practice. | Xiaofeng Zou Guoxi Zhang Tianpeng Xie Yuanhu Yuan Rihai Xiao Gengqing Wu Xiaoning Wang Hui Xu Folin Liu Yuting Wu Yunfeng Liao Quanliang Liu Yinghao Sun Bo Yang Linhui Wang Chuanliang Xu Xiaofeng Gao | 2020 | Asian Journal of Urology2020，7，1： | 5 |
| 2 | A single observer location method under the scatter signals position disturbance situation:the constraint total least square method显示文摘A target position can be estimated using position information from scattered signals in the nonline-of-sight propagation environment in a single observer location system.There is always an error in the final estimated result of the position obtained using scatter signals because measurement noise is inevitable.To reduce the total error of the system,we propose a method of converting the problem of optimizing location into a one of solving the extremes of the constraints.And the problem of how to solve the extremes of the constraints is converted into an unconstrained problem by using the constrained total least squares(CTLS) method.Finally,the Newton iteration method is used to obtain the optimized solution.Simulation results also verify the capability of this method. | YANG TianChi YU ChaoQun2~ WANG TianPeng1 ~ JIN Liang1 YU ChaoQun WANG TianPeng JIN Liang | 2011 | Science China(Information Sciences)2011，54，1： | 3 |
| 3 | The maize late embryogenesis abundant protein Zm DHN13 positively regulates copper tolerance in transgenic yeast and tobacco显示文摘Late embryogenesis abundant (LEA) proteins accumulate in the late stage of plant seed development, and are upregulated in most plants during drought, cold, heat, or salinity stress. LEA proteins can be classified by amino-acid sequence into seven groups. Dehydrins belong to LEA protein group Ⅱ. In previous studies, the maize KS type dehydrin ZmDHN13 increased the tolerance of transgenic tobacco to oxidative stress. In the present study, ZmDHN13 was identified under copper stress conditions, and the protein was then characterized using transgenic yeast and tobacco plants to investigate its functions. ZmDHN13 bound Cu2+. Its overexpression in transgenic tobacco conferred tolerance to copper stress by binding metals and reducing the accumulation of reactive oxygen species (ROS). Three conserved domains displayed a cooperative effect under copper stress conditions. | Yang Liu Daxing Li Qiping Song Tianpeng Zhang Dequan Li Xinghong Yang | 2019 | The Crop Journal2019，7，3： | 3 |

| 5 | Non-planar dielectrics derived thermal and electrostatic field inhomogeneity for boosted weather-adaptive energy harvesting显示文摘Weather-adaptive energy harvesting of omnipresent waste heat and rain droplets,though promising in the field of environmental energy sustainability,is still far from practice due to its low electrical output owing to dielectric structure irrationality and unscalability.Here we present atypical upcycling of ambient heat and raindrop energy via an all-in-one non-planar energy harvester,simultaneously increasing solar pyroelectricity and droplet-based triboelectricity by two-fold,in contrast to conventional counterparts.The delivered non-planar dielectric with high transmittance confines the solar irradiance onto a focal hotspot,offering transverse thermal field propagation towards boosted inhomogeneous polarization with a generated power density of 6.1 mW m^(−2)at 0.2 sun.Moreover,the enlarged lateral surface area of curved architecture promotes droplet spreading/separation,thus travelling the electrostatic field towards increased triboelectricity.These enhanced pyroelectric and triboelectric outputs,upgraded with advanced manufacturing,demonstrate applicability in adaptive sustainable energy harvesting on sunny,cloudy,night,and rainy days.Our findings highlight a facile yet efficient strategy,not only for weather-adaptive environmental energy recovery but also in providing key insights for spatial thermal/electrostatic field manipulation in thermoelectrics and ferroelectrics. | Yi Zhou Tianpeng Ding Yin Cheng Yi Huang Wu Wang Jianmin Yang Lin Xie Ghim Wei Ho Jiaqing He | 2023 | National Science Review2023，10，9： | 0 |
| 6 | Effects of Chemical Reactions in the Hypersonic Reacting Flow around Blunt Bodies显示文摘The effects of chemical reactions in the hypersonic reacting flow are investigated using an integrated algorithm considering simultaneously two different reaction mechanisms,i.e.,including the high temperature air nonequilibrium chemical reactions and the H_2-air combustion reactions. The program is validated by the air non-equilibrium flow at Mach number of 25.9 with the RAM C-II configuration and the shock-induced combustion flow at Mach number of 4.512 6 around a sphere,respectively. Furthermore,the mixed reacting flow with the Mach number of 10.0 with an opposing jet of hydrogen is numerically analyzed. The results show that the program is reliable,and the effects of chemical reactions engender in the decrease of peak temperature along characteristic lines,as well as on the surface. The production of water is augmented in the region with high ratio of oxygen to hydrogen and weakened in the area with low ratio of oxygen to hydrogen by the air chemical non-equilibrium effects. | ZHAO Faming WANG Jiangfeng FAN Xiaofeng YANG Tianpeng | 2019 | Transactions of Nanjing University of Aeronautics and Astronautics2019，36，1： | 0 |
