1Prognostic value of clinicopathological characteristics in patients with pancreatic cancer显示文摘Background:The purpose of this study was to analyze me effects of all clinical characteristics on the overall survival time,in order to provide a basis for determining the prognostic factor of patients with pancreatic cancer.Methods:A total of 103 pancreatic cancer patients were admitted to the Department of Radiotherapy and Chemotherapy of the Ruijin Hospital,Shanghai Jiaotong University School of Medicine,between January 2002 and December 2012.There were 68 men and 35 women;the median age was 62 years.Diagnoses of pancreatic cancer in all patients were confirmed by histopathology,cytology,or clinical diagnosis.The Kaplan-Meier method was performed to calculate the overall survival rate.The log-rank method was used to examine the univariate analysis.The Cox regression model was performed for multivariate analysis.Results:The median survival time was 293 days,the 1-,2-,and 3-year survival rates were 27.18%,5.83%,and 1.94%,respectively.Cox regression analysis revealed that age(P=0.015),Karnofsky performance status(PS)(P=0.002),surgical types(P<0.001),and platelet counts(P<0.001) were independent prognostic factors affecting the overall survival of patients with pancreatic cancer.Conclusions:Pancreatic cancer had a poor prognosis,the general physical condition,age,the availability of radical surgery,and platelet counts were factors influencing the overall survival of patients with pancreatic cancer.Mei Geng Haoping Xu Ruobing Ren Qing Qu Chengfang Shangguan Junwei Wu Jinsong Jiang Hao Li Weiguo Cao 2015Chinese Journal of Cancer Research2015,27,5:4
2The equivalent potential of water molecules for electronic structure of lysine显示文摘In order to get more reliable electronic structures of proteins in aqueous solution, it is necessary to construct a potential of water molecules for protein’s electronic structure calculation. The lysine is a hydrophilic amino acid. It is positively charged (Lys+) in neutral water solution. The first-principles, all-electron, ab initio calcula-tions, based on the density functional theory, have been performed to construct such an equivalent potential of water molecules for lysine (Lys+). The process consists of three parts. First, the electronic structure of the cluster containing Lys+ and water molecules is calculated. By adjusting the positions of water molecules, the geometric structure of the cluster having minimum total energy is determined. Then, based on the structure, the electronic structure of Lys+ with the potential of water molecules is calculated using the self-consistent cluster-embedding (SCCE) method. Finally, the electronic structure of Lys+ with the potential of dipoles is calculated. The dipoles are adjusted so that the electronic structure of Lys+ with the potential of dipoles is close to that of water molecules. Thus the equivalent potential of water molecules for the electronic structure of lysine is obtained. The major effect of water molecules on lysine’s electronic structure is raising the occupied eigenvalues about 0.5032 eV, and broadening energy gap 89%. The effect of water molecules on the electronic structure of lysine can be simulated by dipoles potential.LI ChunJie ZHENG HaoPing WANG XueMei 2007Science China(Physics,Mechanics & Astronomy)2007,50,1:4

6Task scheduling for multi-electro-magnetic detection satellite with a combined algorithm显示文摘Task scheduling for electro-magnetic detection satellite is a typical combinatorial optimization problem. The count of constraints that need to be taken into account is of large scale. An algorithm combined integer programming with constraint programming is presented. This algorithm is deployed in this problem through two steps. The first step is to decompose the original problem into master and sub-problem using the logic-based Benders decomposition; then a circus combines master and sub-problem solving process together, and the connection between them is general Benders cut. This hybrid algorithm is tested by a set of derived experiments. The result is compared with corresponding outcomes generated by the strength Pareto evolutionary algorithm and the pure constraint programming solver--GECODE, which is an open source software. These tests and comparisons yield promising effect.Jianghan Zhu Lining Zhang Dishan Qiu Haoping Li 2012Journal of Systems Engineering and Electronics2012,23,1:1
7Case Based Reasoning Intelligent System for Network Computer Aided Process Planning显示文摘Computer aided process planning system played a key role for integrating design and manufacturing or assembly systems properly considering available resources and design constraints.To take advantage of the enterprise resource,the web CAPP framework was established.Case based reasoning and multi agent system were integrated in the system.The multi agent mecha- nism was discussed in the paper.And an instance of case base was introduced.They made the system run independently and contin- uously in the network environment of process planning problems.ZHAO Chunhua WU Zhengjia ZHOU Chengjun ZHU Dalin LI Haoping School of Mechanical and Material,China Three Gorges University,Yichang 443002,China, 2006武汉理工大学学报2006,28,S3:0
