Intestinal rehabilitation for children with intestinal failure is cost-effective: a simulation study
intestinal failure (home) parenteral nutrition intestinal rehabilitation intestinal transplantation cost-effectiveness
2018/11/12
Background: Children with intestinal failure (IF) depend on parenteral nutrition (PN). The goal in the treatment of IF is to wean children off PN through intestinal rehabilitation (IR). Although the h...
ST段是心电图的重要组成部分，其起始于心电图QRS波群的结束点并结束于T波的开始点。ST段的压低、分上斜形和下垂形压低、水平压低和以及鱼钩样改变都可以反映各种心脏疾病，所以，精确提取心电图ST段具有重要意义。因此。本文提出了基于小波包变换的心电图ST段精确提取算法。方法：首先对心电图信号进行去噪处理，滤去工频干扰信号以及基线漂移信号；然后，提取单周期的心电图信号；最后，引入小波包变换算法提取QRS...

研制用于鼻咽癌放射治疗定位的CT/MRI图像配准辅助装置，并且通过组织勾画差异分析使用该装置后所得配准融合图像在临床中的应用意义。方法 在普通的磁共振头颈线圈中设计特定形状的头枕，保持患者在扫描时与CT定位扫描时相同的体位。采用配对t检验分析CT图像与融合图像中腮腺、下颌骨的勾画差异。结果 患者的头颈部CT、MRI图像的配准精度较未使用该装置的图像具有明显的提高，使用该配准图像得到的融合图像、组织...
提出了一种利用声光调谐方法进行滤波的扫频光源来提高它的输出稳定性。阐述了实现光源稳定输出的原理和方法，研究和分析了光源的相关参数。该系统采用声光调谐的方法代替机械滤波的方式。在一个环形腔内，使用半导体光放大器（SOA）作为增益介质，声光可调谐滤波器（AOTF）作为波长选择元件，利用声光调谐的原理对腔内的光进行选频滤波。在280 mA的注入电流下，得到了1 294~1 368 nm的扫频光源，其中心...
MUC-1在上皮性卵巢癌中的表达及临床病理意义
黏蛋白MUC-1 上皮性卵巢癌 免疫组化
2018/5/25
研究肿瘤相关黏蛋白MUC-1在上皮性卵巢癌中的表达,并探讨MUC-1在上皮性卵巢癌发生、发展中的作用。方法 采用免疫组化PV法测定32例上皮性卵巢癌组织、20例良性卵巢上皮肿瘤组织以及10例同期手术取正常卵巢组织中肿瘤相关黏蛋白MUC-1的表达情况。结果 MUC-1在上皮性卵巢癌中的表达与其在良性卵巢上皮肿瘤、正常卵巢组织中的表达间的差异均有统计学意义(P<0.05);MUC-1表达在后二者间的差...
