肥胖发病率正在以“惊人的”的速度快速增长，已成为严重威胁人类健康的重大问题。设备的发展，3D腹腔镜成像系统逐步踏入普外科手术领域，三维立体图像叠加了传统2D腹腔镜成像系统缺乏纵深感，立体解剖描述不足的劣势，主要是刀医师提供更加清晰的手术视野，使3D腹腔镜作为腹腔镜技术的重大革新，在胃外科手术方面的应用却鲜有报道，与2D腹腔镜比较的优劣情况尚不明了。本研究通过单中心随机对照研究，探讨3D腹腔镜在胃切...
城市AR中，场景结构的自动获取，对自适应信息表达具有重要意义，是解决“层叠式”信息表现形式引发的信息指示不明、场景感知混乱等问题的关键步骤。然而，场景结构信息隐藏在场景图像中，直接提取十分困难。2D地图描述了地理实体的位置、轮廓和空间布局，可作为场景结构提取的先验信息。针对城市AR中场景结构获取难、效率低的问题，本文提出一种基于2D地图的建筑物场景结构自动化提取方法。在地理配准的基础上，首先根据2...
利用2D-STI技术测量肝硬化患者的左室局部收缩功能，探讨不同Child-Pugh分级肝硬化患者左室收缩功能与肝硬化发展程度的相关性与临床价值。 方法 选取肝硬化患者60例为肝硬化组，将患者根据Child-Pugh分级的A、B、C 3个等级对应分为A、B、C 3组；选取与肝硬化组相同时间段内年龄、性别均相匹配的门诊健康体检者30例为正常对照组。测量常规指标，并分析心尖四腔切面、心尖三腔切面和心尖两...

2020/3/18
比较分析3D与2D腹腔镜前列腺癌根治术在前列腺癌治疗中的综合效果及并发症。方法：选取82例行腹腔镜前列腺癌根治术病人，根据手术方式不同分为3D组和2D组，3D组行3D腹腔镜手术治疗，2D组行2D腹腔镜手术治疗，每组各41例，回顾性研究两组病人的临床资料。对两组病人的术中出血量、术中保留性神经、手术时间、尿道重建时间、手术切缘阳性率等指标进行比较，同时对病人术后半年进行随访，对比两组病人术后尿失禁发...
近年来的研究显示，DENN/MADD 域内含蛋白 2D（DENND2D）作为一种抑癌基因，其过表达可以诱导细胞凋亡，从而显著地抑制肿瘤细胞在体外和体内的增殖。其机制为DENND2D通过对PARP的剪切使凋亡标志物cleaved PARP 表达增高，以及竞争性抑制MADD与肿瘤细胞死亡结构域的结合等。而在非小细胞肺癌（non-small cell lung cancer，NSCLC）患者肿瘤细胞中D...
