目的研究内镜下黏膜切除术和黏膜剥离术对结直肠癌前病变及早癌的治疗价值。方法抽取2017年2月~2018年2月本院行内镜下黏膜切除术(Endoscopic Mucosal Resection,EMR)的结直肠癌前病变及早癌患者38例作为A组,另选择同期接收并行内镜下黏膜剥离术(Endoscopic submucosal dissection,ESD)的结直肠癌前病变及早癌患者38例作为B组,对比两组治疗的疗效。结果 A组总平均手术时间、并发症发生率优于B组,差异有统计学意义(P<0.05);但B组病变直径≥2.0 cm的完全切除率、整块切除率以及病灶残留率、复发率均优于A组,差异有统计学意义(P<0.05)。结论 EMR、ESD治疗结直肠癌前病变及早癌的疗效相当,而后者对治疗病变直径≥2.0 cm的效果更佳;但ESD对手术操作的要求高,因此,应综合考虑病变位置、病灶大小、病例类型等选择适宜的治疗方案,并加强对术后的监测。

在自动化装配线上轮胎与轮毂装配时,需要检测与识别轮胎表面的压印字符串,从而得到轮胎的品牌、型号、尺寸以及生产的年周号等信息,用以管理轮胎信息以及监控轮胎的流向。针对轮胎表面压印字符串的检测与识别问题,文章提出一种基于深度学习的轮胎胎面关键字符的检测与识别方法,搭建了可编程逻辑控制器(programmable logic controller,PLC)、工控机和工业相机的自动化检测与识别平台,通过霍夫变换及坐标变换对采集后的图像进行预处理,采用改进的更快速的区域卷积神经网络(faster region-based convolutional neural network,Faster RCNN)算法为基础检测出目标字符串位置,再通过卷积递归神经网络(convolutional recurrent neural network,CRNN)对检测出的目标字符串进行识别,同时利用编码规则校验识别结果,以提升识别结果的准确率。实验结果表明,改进后的算法在进行轮胎压印字符串的检测与识别时其准确率超过97.0%,满足工业生产应用需求。
