In recent years, remote ECG monitoring systems have been applied in the monitoring of various kinds of heart diseases, and the quality of the transmission and re- ception of the ECG signals during remote process kept advancing. However, there remains accompanying challenges. This report focuses on the three components of the remote ECG monitoring system： patient （the end user）, the doctor workstation, and the remote server, reviewing and evaluating the imminent challenges on the wearable systems, packet loss in remote transmission, portable ECG monitoring system, pa- tient ECG data collection system, and ECG signals transmission including real-time processing ST segment, R wave, RR interval and QRS wave, etc. This paper tries to clarify the future developmental strategies of the ECG remote monitoring, which can be helpful in guiding the research and development of remote ECG monitoring.展开更多
文摘目的探讨白细胞介素-6(interleukin-6,IL-6)表达水平在上皮性卵巢癌(epithelial ovarian canc-er,EOC)中的临床价值,并基于生物信息学预测IL-6对EOC发生、发展的潜在机制.方法ELISA法检测21例不同国际妇产科联盟(International Federation of Gynecology and Obstetrics,FIGO)手术-病理分期的EOC患者、12例良性卵巢疾病患者和30例健康体检妇女的血清IL-6水平.从公共基因表达(gene expression omni-bus,GEO)数据库和癌症基因组图谱(the cancer genome atlas,TCGA)数据库收集共计897例EOC组织样本的基因表达谱,根据IL-6高低表达分组筛选差异基因,进行GO和KEGG通路富集分析.绘制IL-6相关基因所编码蛋白的相互作用网络图,提取IL-6所在的核心网络模块.结果血清IL-6在EOC患者的水平显著高于正常对照组(P=0.031),与FIGOⅠ~Ⅳ期呈正相关(r=0.79,P=0.002);基于TCGA数据库挖掘的IL-6基因表达水平在发生脉管浸润时上调(P=0.027),且随FIGOⅠ~Ⅲ依次升高;从4个卵巢癌数据集筛选出199个共同差异基因,富集于细胞外基质重塑、细胞粘附、炎性反应、病原体免疫识别等功能和相应的信号通路;初步鉴定出CCL2、PTPRC、CD163可能为IL-6在EOC中发挥作用的关键分子.结论血清IL-6可为EOC的复发和转移提供实验室证据,生物信息学分析提示IL-6相关基因主要与EOC的侵袭和转移等生物学特性有关,IL-6用于评估病情进展的具有临床意义.
