| 1 | Severity of early allograft dysfunction following donation after circulatory death liver transplantation:a multicentre study显示文摘Background:Early allograft dysfunction(EAD)is associated with decreased graft and patient survival rates.This study aimed to identify the severity of EAD and develop a predictive model for EAD after donation after circulatory death(DCD)liver transplantation(LT).Furthermore,the influence of operative time on EAD incidence was also evaluated.Methods:In this retrospective,multicentre cohort study,nomograms were established based on a single-centre training cohort(n=321)and validated in a 3-center validation cohort(n=501).Results:The incidence rate of EAD was 46.4%(149/321)in the training cohort and 40.5%(203/501)in the validation cohort.Of the 149 EAD patients in the training cohort,77 patients with either elevated alanine aminotransferase(ALT)or aspartate aminotransferase(AST)were classified as having EAD type A,and the rest of the EAD patients were classified as having EAD type B.Recipients with EAD type B had lower graft and patient survival rates than recipients with EAD type A(P=0.043 and 0.044,respectively).We further developed a nomogram to predict EAD(graft weight,cold ischemia time,donor age,model for end-stage liver disease(MELD)score)and another nomogram to predict EAD type B(graft weight,cold ischemia time,MELD score).The nomograms for the prediction of EAD and EAD type B had good discrimination[concordance index(C-index)=0.712(0.666-0.758),0.707(0.641-0.773)]and calibration[Hosmer-Lemeshow(HL)P=0.384,P=0.425]in the validation cohort.An increased operative time(>6 h)was associated with increased EAD and EAD type B incidence in the high-risk group(P=0.005,P=0.020,respectively).Conclusions:EAD type B was associated with decreased graft and patient survival rates.The novel nomograms effectively predicted the incidence of EAD and EAD type B in DCD LT patients. | Kun Wang Di Lu Yuhui Liu Wangyao Li Li Zhuang Zhenyu Ma Qinfen Xie Binhua Pan Yichao Wu Junli Chen Lidan Lin Xiaowen Feng Qiang Wei Xuyong Wei Haiyang Xie Zhengxin Wang Shusen Zheng Xiao Xu | 2021 | Hepatobiliary Surgery and Nutrition2021，10，1： | 4 |

| 3 | Message from Editors显示文摘ELECTRICAL machine systems have found extensive applications,for which various machine topologies have been proposed in the recent years.Performance analysis and optimal design with theoretical methods and multi-field finite element methods are key issues for developing high-end products.Meanwhile,control strategies linked with specific machine topologies and design considerations are rather beneficial for the electrical machine systems,in the aspects of energy efficiency,output smoothness,control precision,dynamic response,and many others. | Jian-Xin Shen Dianguo Xu Xiaoyan HUANG Qinfen LU Heng NIAN Pierre-Daniel PFISTER Huan YANG Taiying ZHENG | 2017 | CES Transactions on Electrical Machines and Systems2017，1，2： | 0 |
| 4 | NEW PUNCHING MACHINE DRIVEN BY LINEAR INDUCTION MOTOR显示文摘The research and application of the punching machine driven by a linear induction motor(LIM)are introduced.The fundamental principle, construction, performance and application are described. Comparing this new model machine with its traditional form, the LIM driven punching machine has many great advantages, such as, simple construction, small size and mass, low production cost, short production time, easy to control, low noise and considerable energy saving. | Ye Yunyue Wu Changchun Lu Qinfen | 2000 | Chinese Journal of Mechanical Engineering2000，13，3： | 0 |
