经胃镜植入化疗粒子联合DC-CIK治疗老年食管癌

目的探讨经胃镜植入化疗粒子联合DC-CIK免疫细胞输注法治疗老年食管癌的效果。方法选取106例老年食管癌患者,按就诊先后分成观察组(n=53)和对照组(n=53),对照组采用经胃镜植入化疗粒子治疗,观察组采用经胃镜植入化疗粒子联合DC-CIK免疫细胞输注法治疗,观察两组患者客观缓解率(ORR)、疾病控制率(DCR)及1年生存率。结果观察组ORR、DCR均高于对照组,观察组1年生存率(73.58%)高于对照组(54.72%),差异有统计学意义(P<0.05)。结论经胃镜植入化疗粒子联合DC-CIK免疫细胞输注法治疗老年食管癌具有明显效果,可有效控制疾病,提高生存率。

胃镜下支架植入术治疗食道狭窄疗效分析

目的:研究食道支架植入术治疗食道恶性狭窄的疗效。方法:对30例晚期食道癌患者行胃镜下支架植入术治疗食道狭窄,观察手术治疗效果及并发症情况。结果:30例患者治疗后症状均得到明显缓解,部分患者出现出血、支架堵塞等并发症,经对症处理后缓解。结论:应用食道支架植入术治疗食道恶性狭窄具有良好的疗效,并且安全可靠。

介入化疗联合胃镜下粒子植入治疗中晚期胃癌的疗效观察

目的:本研究旨在观察两种方法联合治疗中晚期胃癌患者的疗效,通过对患者生存时间、生活质量改善等情况的随访明确联合治疗优势,为临床推广提供理论依据。方法:按照自愿选择的原则,将接受治疗的患者分为两组,其中对照组20例单纯行选择性腹腔动脉灌注化疗,选择一支或多支灌注化疗药物奥沙利铂、羟基喜树碱、亚叶酸钙;观察组18例除给予对照组治疗外联合经胃镜下植入5-Fu缓释粒子治疗。结果:观察组共18例,(CR+PR)16例,总有效率达89.99%,对照组共20例,(CR+PR)11例,总有效率55%;同时观察组生存率及生活质量较对照组均有明显提高。结论:对中晚期胃癌患者,选择性腹腔动脉灌注化疗联合胃镜下粒子植入化疗较单纯行选择性腹腔动脉灌注化疗疗效有明显提高,患者生存率及生活质量均有不同程度提高。

A wireless endoscope based on an embedded system

We presented a wireless endoscope system developed on the embedded Linux platform. This wireless endoscope system consists of three parts: the endoscope capsule,the portable equipment and the image workstation,which make this system wireless and portable. Hardware design of this system and software design of the portable equipment are described. In clinical use,patients swallow the endoscope capsule for gastrointestinal inspection. The portable equipment receives images of gastrointestinal tract via the radio frequency module while it sets and reads back parameters of the capsule via the low frequency module. Acquired image data can be saved as a FAT32 format file in an universal serial bus disk. Images can be processed and reviewed at an Microsoft Windows PC workstation in the next stage. The image acquired by this wireless endoscope system is quite effective with clear details of gastrointestinal tract. However,the endoscope capsule was large,making it difficult to swallow. So the printed circuit board design of endoscope capsule needs to be improved.
