| 1 | Percent free prostate-specific antigen for prostate cancer diagnosis in Chinese men with a PSA of 4.0-10.0 ng/mL:Results from the Chinese Prostate Cancer Consortium显示文摘Objective:To test the diagnostic performance of percent free prostate-specific antigen(%fPSA)in predicting any prostate cancer(PCa)and high-grade prostate cancer(HGPCa)in a retrospective multi-center biopsy cohort with a PSA level of 4.0e10.0 ng/mL in China.Methods:Consecutive patients with a PSA of 4.0-10.0 ng/mL who underwent transrectal ultrasound-guided biopsy were enrolled at 16 Chinese medical centers from January 1st,2010 to December 31st,2013.Total and free serum PSA determinations were performed using three types of electro-chemiluminescence immunoassays recalibrated to the World Health Organization(WHO)standard.The diagnostic accuracy of PSA,%fPSA,and %fPSA in combination with PSA(%fPSA t PSA)was determined using the area under the receiver operating characteristic(ROC)curve(AUC).Results:A total of 2310 consecutive men with PSA levels between 4.0 and 10.0 ng/mL were included,and the detection rate of PCa was 25.1%.The AUC of%fPSA and %fPSA t PSA in predicting any PCa was superior to PSA alone in men aged≥60 years(0.623 vs.0.534,p<0.0001)but not in men aged 40e59 years(0.517 vs.0.518,p=0.939).Similar result was yield in predicting HGPCa.Conclusion:In a clinical setting of Chinese men with 4.0e10.0 ng/mL PSA undergoing initial prostate biopsy,adding %fPSA to PSA can moderately improve the diagnostic accuracy for any PCa and HGPCa compared with PSA alone in patients≥60 but not in patients aged 40-59 years. | Rui Chen Liping Xie Xiaobing Cai Yiran Huang Liqun Zhou Lulin Ma Xu Gao Chuanliang Xu Shancheng Ren Pengfei Shao Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Li Lu Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tie Zhou Fubo Wang Biming He Yinghao Sun | 2015 | Asian Journal of Urology2015，2，2： | 8 |
| 2 | A phase 3,double-blind,randomized placebo-controlled efficacy and safety study of abiraterone acetate in chemotherapynaı¨ve patients with mCRPC in China,Malaysia,Thailand and Russia显示文摘Objective:This double-blind,placebo-controlled phase 3 study was designed to compare efficacy and safety of abiraterone acetate+prednisone(abiraterone)to prednisone alone in chemotherapy-naı¨ve,asymptomatic or mildly symptomatic metastatic castrationresistant prostate cancer(mCRPC)patients from China,Malaysia,Thailand and Russia.Methods:Adult chemotherapy-naı¨ve patients with confirmed prostate adenocarcinoma,Eastern Cooperative Oncology Group(ECOG)performance status(PS)grade 0e1,ongoing androgen deprivation(serum testosterone<50 ng/dL)with prostate specific antigen(PSA)or radiographic progression were randomized to receive abiraterone acetate(1000 mg,QD)t prednisone(5 mg,BID)or placebo t prednisone(5 mg,BID),until disease progression,unacceptable toxicity or consent withdrawal.Primary endpoint was improvements in time to PSA progression(TTPP).Results:Totally,313 patients were randomized(abiraterone:n Z 157;prednisone:n Z 156);and baseline characteristics were balanced.At clinical cut-off(median follow-up time:3.9 months),80% patients received treatment(abiraterone:n Z 138,prednisone:n Z 112).Median time to PSA progression was not reached with abiraterone versus 3.8 months for prednisone,attaining 58%reduction in PSA progression risk(HR=0.418;p<0.0001).Abirateronetreated patients had higher confirmed PSA response rate(50%vs.21%;relative odds=2.4;p<0.0001)and were 5 times more likely to achieve radiographic response than prednisonetreated patients(22.9%vs.4.8%,p=0.0369).Median survival was not reached.Most common(≥10% abiraterone vs.prednisone-treated)adverse events:bone pain(7%vs.14%),pain in extremity(6%vs.12%),arthralgia(10%vs.8%),back pain(7%vs.11%),and hypertension(15%vs.14%).Conclusion:Interim analysis confirmed favorable benefit-to-risk ratio of abiraterone in chemotherapy-naı¨ve men with mCRPC,consistent with global study,thus supporting use of abiraterone in this patient population. | Dingwei Ye Yiran Huang Fangjian Zhou Keji Xie Vsevolod Matveev Changling Li Boris Alexeev Ye Tian Mingxing Qiu Hanzhong Li Tie Zhou Peter De Porre Margaret Yu Vahid Naini Hongchuan Liang Zhuli Wu Yinghao Sun | 2017 | Asian Journal of Urology2017，4，2： | 3 |
| 3 | A Rate of Convergence of Physics Informed Neural Networks for the Linear Second Order Elliptic PDEs显示文摘In recent years,physical informed neural networks(PINNs)have been shown to be a powerful tool for solving PDEs empirically.However,numerical analysis of PINNs is still missing.In this paper,we prove the convergence rate to PINNs for the second order elliptic equations with Dirichlet boundary condition,by establishing the upper bounds on the number of training samples,depth and width of the deep neural networks to achieve desired accuracy.The error of PINNs is decomposed into approximation error and statistical error,where the approximation error is given in C2 norm with ReLU^(3)networks(deep network with activation function max{0,x^(3)})and the statistical error is estimated by Rademacher complexity.We derive the bound on the Rademacher complexity of the non-Lipschitz composition of gradient norm with ReLU^(3)network,which is of immense independent interest. | Yuling Jiao Yanming Lai Dingwei Li Xiliang Lu Fengru Wang Yang Wang Jerry Zhijian Yang | 2022 | Communications in Computational Physics2022，31，4： | 2 |
| 4 | Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors. | Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang | 2019 | Asian Journal of Urology2019，6，1： | 2 |

| 9 | An on-line tool path smoothing algorithm for 6R robot manipulator with geometric and dynamic constraints显示文摘The tool path smoothness of the industrial robot directly influences the dynamic performance of its motion control. Therefore, it is important to smooth the path that is composed of small linear segments, in order to achieve continuous and smooth movement.This paper uses the FIR filter interpolation method to generate the smooth tool tip position and tool orientation trajectory for robot manipulators with 6 rotational(6R) joints. The geometric smoothness and motion interpolation are achieved in one step.The maximum velocity and acceleration of joints are constrained when calculating the time parameters of the FIR filter. By specially designing the overlapping time at transition corners, the tool tip position and tool orientation deviations are all constrained in the workpiece coordinate system. Considering the complexity of the inverse kinematics of the robot, in order to constrain the velocity and acceleration of robot joints, this paper proposes a simplified method which directly establishes the relationship between joint motion and tool motion through the derivative of joint motion to tool motion without considering the inverse kinematics. Simulation and experiment results show that the algorithm can generate continuous acceleration commands of the tool tip position and tool orientation within the corner error tolerance. The preset velocity and acceleration limitations of six joints are all constrained well. Comparisons with existing algorithms demonstrate advantages of the proposed method. | SUN HongWei YANG JiXiang LI DingWei DING Han | 2021 | Science China(Technological Sciences)2021，64，9： | 1 |
| 10 | Equivalent damping of SDOF structure with Maxwell damper显示文摘To predict the maximum earthquake response of an SDOF structure with a Maxwell fluid damper or supplemental brace-viscous damper system using the seismic design response spectrum technique,a new approach is presented to determine the first-and second-order equivalent viscous damping and stiffness,the peak responses,and the damper force of the above structure.Based on the fact that the dynamic characteristics of a general linear viscoelastically damped structure are fully determined by its free vibration properties and the relaxation time constants of a Maxwell fluid damper and supplemental brace-viscous damper system in engineering practice are all small,the method of improved multiple time scales and the equivalent criterion in which all free vibration properties are the same are used to obtain the first-and second-order equivalent viscous damping and stiffness of the above structure in closed form.The accuracy of the proposed method is higher and significantly better than that of the modal strain energy method.Furthermore,in the parametric range of the requirements of the Chinese 'Code for Seismic Design of Buildings',the error of the proposed second-order equivalent system for the abovementioned engineering structure is not more than 0.5%. | Li Chuangdi Li Tun Ban Dingwei Ge Xinguang | 2018 | Earthquake Engineering and Engineering Vibration2018，17，3： | 1 |
| 11 | Response of Chinese fir seedlings to low phosphorus stress and analysis of gene expression differences显示文摘Chinese fir(Cunninghamia lanceolata) is an excellent fast-growing timber species occurring in southern China and has significant value in the forestry industry. In order to enhance the phosphorus utilization efficiency in Chinese fir, four clones named X6, S3, S39 and FK were used, and low phosphorus(LP) stress experiments were performed to analyze the response of different clones to phosphorus deficiency. According to the results on seedling height, maximum root length, leaf blade aspect ratio, root ratio, malondialdehyde content, acid phosphates activity,proline content, soluble protein level, and chlorophyll a and b levels of the tested clones, compared to the control groups(CK), the phosphorus high efficiency clone X6 was screen out for transcriptome sequencing experiments. De novo RNA-seq was then used to sequence the root transcriptomes of X6 under LP stress and CK, and we then compared the gene expression differences under the two conditions. A total of 3416 SDEGs were obtained by comparing the LP and CK groups, among which 1742 were up-regulated and 1682 were down-regulated. All SDEGs obtained from the LP and CK treated samples were subjected to KEGG annotation and classification. Through classification statistical analysis using WEGO software,607 SDEGs obtained KEGG pathway annotations, which were related to 206 metabolic pathways. In Chinese fir subjected to LP stress, 53 SDEGs related with phosphorus metabolism, and phosphate uptake and transport were obtained from our transcriptome data. Based on the phosphorus metabolism pathway obtained by KEGG classification, combined with previously report on gene annotation related with phosphorus metabolism, the enzymes encoded by SDEG related with phosphorus metabolism and their expression pattern were mapped onto phosphorus metabolism pathway. | Jianhui Li Dingwei Luo Guifang Ma Licui Jia Jinliang Xu Huahong Huang Zaikang Tong Yong-Quan Lu | 2019 | Journal of Forestry Research2019，30，1： | 1 |
| 12 | Fully Printed High‑Performance n‑Type Metal Oxide Thin‑Film Transistors Utilizing Coffee‑Ring Effect显示文摘Metal oxide thin-films transistors(TFTs)produced from solution-based printing techniques can lead to large-area electronics with low cost.However,the performance of current printed devices is inferior to those from vacuum-based methods due to poor film uniformity induced by the“coffeering”effect.Here,we report a novel approach to print highperformance indium tin oxide(ITO)-based TFTs and logic inverters by taking advantage of such notorious effect.ITO has high electrical conductivity and is generally used as an electrode material.However,by reducing the film thickness down to nanometers scale,the carrier concentration of ITO can be effectively reduced to enable new applications as active channels in transistors.The ultrathin(~10-nm-thick)ITO film in the center of the coffee-ring worked as semiconducting channels,while the thick ITO ridges(>18-nm-thick)served as the contact electrodes.The fully inkjet-printed ITO TFTs exhibited a high saturation mobility of 34.9 cm2 V^(−1) s^(−1) and a low subthreshold swing of 105 mV dec^(−1).In addition,the devices exhibited excellent electrical stability under positive bias illumination stress(PBIS,ΔV_(th)=0.31 V)and negative bias illuminaiton stress(NBIS,ΔV_(th)=−0.29 V)after 10,000 s voltage bias tests.More remarkably,fully printed n-type metal–oxide–semiconductor(NMOS)inverter based on ITO TFTs exhibited an extremely high gain of 181 at a low-supply voltage of 3 V,promising for advanced electronics applications. | Kun Liang Dingwei Li Huihui Ren Momo Zhao Hong Wang Mengfan Ding Guangwei Xu Xiaolong Zhao Shibing Long Siyuan Zhu Pei Sheng Wenbin Li Xiao Lin Bowen Zhu | 2021 | Nano-Micro Letters2021，13，11： | 1 |

| 15 | Convergence Rate Analysis for Deep Ritz Method显示文摘Using deep neural networks to solve PDEs has attracted a lot of attentions recently.However,why the deep learning method works is falling far behind its empirical success.In this paper,we provide a rigorous numerical analysis on deep Ritz method(DRM)[47]for second order elliptic equations with Neumann boundary conditions.We establish the first nonasymptotic convergence rate in H^(1)norm for DRM using deep networks with ReLU^(2)activation functions.In addition to providing a theoretical justification of DRM,our study also shed light on how to set the hyperparameter of depth and width to achieve the desired convergence rate in terms of number of training samples.Technically,we derive bound on the approximation error of deep ReLU^(2)network in C^(1)norm and bound on the Rademacher complexity of the non-Lipschitz composition of gradient norm and ReLU^(2)network,both of which are of independent interest. | Chenguang Duan Yuling Jiao Yanming Lai Dingwei Li Xiliang Lu Jerry Zhijian Yang | 2022 | Communications in Computational Physics2022，31，4： | 0 |
