| 1 | 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 |
| 2 | Recent advances in fabrication of monolayer colloidal crystals and their inverse replicas显示文摘Monolayer colloidal crystals(MCCs)are two-dimensional(2D)colloidal crystals consisting of a monolayer of monodisperse colloidal particles arrayed with a 2D periodic order.In recent years,MCCs have attracted intensive interest because they can act as 2D photonic crystals and be used as versatile templates for fabrication of various 2D nanostructure arrays.In this review,we provide an overview of the recent progress in the controllable fabrication of MCCs and their inverse replicas.First,some newly-developed methods for the self-assembly of MCCs based on different strategies including interfacial assembly and convective assembly are introduced.Second,some representative novel methods regarding the fabrication of various functional2D inverse replicas of MCCs,such as 2D arrays of nanobowls,nanocaps,and hollow spheres,as well as 2D monolayer inverse opals(MIOs),are described.In addition,the potential applications of MCCs and their inverse replicas are discussed. | YE XiaoZhou QI LiMin | 2014 | Science China Chemistry2014，57，1： | 5 |
| 3 | A quantitative research on the level of disturbance to secondary signal ports of electronic voltage transformers under the operation of gas‐insulated switchgear显示文摘The collectors of electronic transformers has the problem of electromagnetic in-compatibility under the operation of disconnecting switches,which limits their wide application in smart grids.To evaluate the maximum level of disturbance that collectors are able to withstand in the stochastic process of switching operation,this work in-troduces a quantitative approach based on limited test measurements,which can quantify the level of disturbance in the signal acquisition ports of electronic voltage transformers(EVT)in different gas‐insulated switchgears(GIS).Based on large numbers of experi-mental statistical data of the true type simulation experimental platform,the Spearman rank correlation coefficient is used to prove that the amplitude of the disturbance voltage pulse at the secondary side port and the breakdown voltage between the primary side fracture approximately satisfy a linear relationship.Subsequently,the quantile regression model is used to quantify and verify the maximum disturbance level of the secondary side port.Moreover,a solution is proposed to tackle the difficulty in obtaining the breakdown voltage at breaks in the GIS substation field applicatvion,under which the quantified maximum disturbance voltage deviation of secondary ports is only−4.34%by com-parison.The research work can further explore the practical value of the measured data in a few tests under GIS substation field conditions and provide references for the sub-sequent revision of EVT‐related standards. | Qi Wang Chao Fu Fanwu Chu Yue Tong Xiaozhou Wang Guoxiong Ye Xiong Wu | 2022 | High Voltage2022，7，1： | 2 |

| 5 | Survival after radical cystectomy for bladder cancer:Multicenter comparison between minimally invasive and open approaches显示文摘Objective:To investigate oncological outcomes in patients with bladder cancer who underwent minimally invasive radical cystectomy(MIRC)or open radical cystectomy(ORC).Methods:We identified patients with bladder cancer who underwent radical cystectomy(RC)in 13 centers of the Chinese Bladder Cancer Consortium(CBCC).Perioperative outcomes were compared between MIRC and ORC.The influence of surgical approaches on overall survival(OS)and cancer-specific survival(CSS)in the entire study group and subgroups classified according to pathologic stage or lymph node(LN)status was assessed with the log-rank test.Multivariable Cox proportional hazard models were used to evaluate the association among OS,CSS and risk factors of interest.Results:Of 2098 patients who underwent RC,1243 patients underwent MIRC(1087 laparoscopic RC and 156 robotic-assisted RC,respectively),while 855 patients underwent ORC.No significant differences were noted in positive surgical margin rate and 90-day postoperative mortality rate.MIRC was associated with less estimated blood loss,more LN yield,higher rate of neobladder diversion,longer operative time,and longer length of hospital stay.There was no significant difference in OS and CSS according to surgical approaches(pZ0.653,and 0.816,respectively).Subgroup analysis revealed that OS and CSS were not significantly different regardless of the status of extravesical involvement or LN involvement.Multivariable Cox regression analyses showed that the surgical approach was not a significant predictor of OS and CSS.Conclusions:Our study showed that MIRC was comparable to conventional ORC in terms of OS and CSS. | Weibin Xie Junming Bi Qiang Wei Ping Han Dongkui Song Lei Shi Dingwei Ye Yijun Shen Xin Gou Weiyang He Shaogang Wang Zheng Liu Jinhai Fan Kaijie Wu Zhiwen Chen Xiaozhou Zhou Chuize Kong Yang Liu Chunxiao Liu Abai Xu Baiye Jin Guanghou Fu Wei Xue Haige Chen Tiejun Pan Zhong Tu Tianxin Lin Jian Huang | 2020 | Asian Journal of Urology2020，7，3： | 1 |
| 6 | A Layout Method of Space-Based Pseudolite System Based on GDOP Geometry显示文摘The pseudolite system can be used to provide positioning and timing service for users in a specific area.In order to provide better positioning and timing service,a good geometric configuration needs to be formed for the pseudolite system.For the problem of pseudolite system deployment,the average and mean square values of geometric dilution of precision(GDOP)are optimized in this paper for users in a target area.We proposed a space-based pseudolite deployment method based on GDOP geometry,starting from the minimum GDOP value for users in the central area.From the simulation results,it can be seen that,compared with the empirical method and the NSGA-II method,the method in this paper has the smallest average GDOP,a better robustness,and a higher positioning accuracy in the target area,through which a pseudolite deployment proposal can be quickly obtained. | YANG Xin WANG Feixue LIU Wenxiang XIAO Wei YE Xiaozhou | 2023 | Chinese Journal of Electronics2023，32，5： | 0 |
| 7 | Memory Copy Optimization for Streaming Gateway Transcoding:Models and Algorithms显示文摘Repeated memory copy during protocol translation inhibits capacity of a streaming media gateway.Unlike existing optimization techniques that rely on platform-specific features,this paper investigates algorithm-level platform-independent strategies.A mathematical concept of the buf-string is proposed to model the protocol transcoding process.Based on this model three payload extraction algorithms that can reduce memory copy are presented.The streaming gateway used in the Next-generation broadcasting(NGB) and the Nextgeneration on-demand(NGOD) system is taken as an example to demonstrate and evaluate our strategies.Experimental results from an x86 host and an embedded system prove that our strategies can reduce CPU overhead by 15%to 45%,and optimize the linear space complexity to a constant one. | LI Mingzhe WANG Jinlin CHEN Xiao YE Xiaozhou | 2016 | Chinese Journal of Electronics2016，25，4： | 0 |
| 8 | Effect of Al_2O_3-SiC Composite Powder on Properties of Al_2O_3-SiC一C Bricks显示文摘Al2O3- SiC- C specimens were prepared using white fused corundum( 3- 1,≤1 and ≤0. 044 mm),Al2O3- SiC composite powders( d50≤5 μm),α-Al2O3micropowder( d50= 1. 2 μm),SiC powder( ≤0. 044mm),flake graphite( ≤0. 088 mm),Si powder( d50= 42. 8 μm) and B4C powder( d50≤10 μm) as main starting materials,and thermosetting phenolic resin as binder. 4%,8%,12% and 16%( in mass,the same hereinafter) of Al2O3- SiC composite powders substituted the same quantity of α-Al2O3micropowder + SiC powder.Effects of composite powder additions on apparent porosity,bulk density,cold modulus of rupture,cold crushing strength,hot modulus of rupture( 1 400 ℃),therma shock resistance( 1 100 ℃,water quenching) and oxidation resistance( 1 000 and 1 500 ℃) of Al2O3- SiC- C specimens after 180 ℃ curing,1 000 ℃ 3 h carbon-embedded firing and 1 500 ℃ 3 h carbon-embedded firing,respectively,were researched. The results indicate that:( 1) with the increase of Al2O3- SiC composite powder,cold strengths of the cured specimens decline,those of the specimens fired at 1 000 ℃ change a little,and those of the specimens fired at 1 500 ℃ change a little except for an obvious improvement of cold crushing strength;( 2) with the increase of Al2O3- SiC composite powder,hot modulus of rupture at 1 400 ℃ decreasesand thermal shock resistance enhances significantly;( 3) when Al2O3- SiC composite powder addition is4%,the oxidation resistance at 1 500 ℃ is the best,and the reason may be the composite powder is finer and more active,which is beneficial to form dense mullite protective layer to retard the O2diffusion into the specimens. | WANG Changchun YE Fangbao CHEN Huaduo YE Xiaozhou | 2014 | China's Refractories2014，23，1： | 0 |
| 9 | Nonlinear effects of the finite amplitude ultrasound wave in biological tissues显示文摘Nonlinear effects will occur during the transmission of the finite amplitude wave in biological tissues. The theoretical prediction and experimental demonstration of the nonlinear effects on the propagation of the finite amplitude wave at the range of biomedical ultrasound frequency and intensity are studied. Results show that the efficiency factor and effective propagation distance will decrease while the attenuation coefficient increases due to the existence of nonlinear effects. The experimental results coincided quite well with the theory. This shows that the effective propagation distance and efficiency factor can be used to describe quantitatively the influence of nonlinear effects on the propagation of the finite amplitude sound wave in biological tissues. | Xiaozhou Liu Xiufen Gong Shigong Ye Weiya Zhang | 2000 | Chinese Science Bulletin2000，45，6： | 0 |
