Background:Gallbladder cancer(GBC)was once considered a contraindication for laparoscopic surgery,but it is becoming more common to use laparoscopic surgery for GBC *** aim of this study was to analyze the long-and short-term outcomes of patients with more advanced T-staged GBC treated with curative intent as defined by the National Comprehensive Cancer Network(NCCN)after laparoscopic resection(LR)versus open resection(OR).Methods:A multicenter database was used to select consecutive GBC patients treated with curative-intent resection as defined by the NCCN between 2016 and *** patients were divided into the LR group and the OR *** score matching(PSM)was used to eliminate selection *** endpoints were overall survival(OS),progression-free survival(PFS),and short-term *** factors that were independently associated with OS and PFS were ***:Of 626 GBC patients treated with curative-intent resection,after PSM,51 patients were in the LR group and 153 patients were in the OR *** LR group had more patients who were suitable to receive adjuvant chemotherapy(AC),a longer operation time,more harvested lymph nodes,and a lower overall morbidity *** rates of OS and PFS were not significantly different between the two *** was independently associated with better OS and ***:The overall morbidity of GBC patients after LR was lower,but the long-term outcomes between LR and OR were not significantly *** GBC patients treated with LR were more likely to receive AC,and the use of AC after curative-intent resection of GBC helped achieve better long-term survival outcomes.

与传统的制造过程相比,发动机试验过程中的复杂性和不确定性使得这类问题的效率提升更加难以处理。在详细分析航空发动机试验业务场景和一般流程的基础上,本文首先提出衡量发动机试验效率的综合指标,并对影响试验效率的关键因素进行研究。基于精益生产的工具和技术方法,结合效率的综合衡量指标,文章通过对发动机试验全流程的价值流分析,识别试验过程中的增值和非增值活动,对流程时间占比较大的非增值环节上下台过程进行梳理和优化,进一步缩短发动机占台准备时间。最后,本文的研究成果在某企业试验台进行验证,相关改进工作可以推广到其它试验过程。

基于传统和第五次人口普查两种口径,结合相关模型分析了江苏省城市规模分布的时空演变特征:①城市体系规模结构基本满足位序—规模分布规律,分布的集中性趋于减弱而均衡程度则趋于增强;②城市GNI指数的区域差异明显,苏南>苏北>苏中;③统计口径影响很大,相比而言,五普口径较传统口径能够更加真实地反映城市规模分布演变的总体趋势。研究表明,经济因素与城市规模分布变动呈明显的相关性,但政治结构因素(行政区划调整和统计口径)是引起城市规模分布演变的根本原因。

为制备高纵横比的纳米硅尖,研究了掩模的偏转方向对硅尖形状的影响。设计了硅尖制备的工艺流程,采用KOH溶液湿法各向异性腐蚀(100)单晶硅的方法制备硅尖,根据实验结果和{411}晶面模型,分析了硅尖侧壁的组成晶面,讨论了掩模偏转方向对硅尖形状的影响,得到了制备高纵横比纳米硅尖的工艺参数。实验结果表明:当腐蚀溶液浓度和温度一定时,正方形掩模的方向并不影响快腐蚀晶面的类型,利用正方形掩模的偏转,可以制备出八面体和四面体的硅尖。当正方形掩模边缘沿〈110〉晶向时,在78℃、浓度为40%的KOH溶液中腐蚀硅尖,经980℃干氧氧化3h进行削尖,可制备出纵横比>2的八面体纳米硅尖阵列,硅尖侧壁由与(100)面夹角为76.37°的{411}晶面组成。
