中文摘要: 将毛细管电泳(CE)的高分离能力,与安培检测器(AD)的高灵敏度、高选择性,以及电容耦合非接触电导检测器(C4D)的响应通用性相结合,研制了新型、高性能的毛细管电泳-双电化学检测分析系统(μ-AD/C4D);以苯丙酮尿症(PKU)为代表的先天性氨基酸代谢病(inborn errors of amino acid metabolism)和DNA氧化损伤为研究示例,着重研究了其相关疾病标志化合物(mark compounds)检测的优化条件及抗干扰能力,以及标志化合物在血液、尿液、唾液等不同体液中的分布规律,探索了通过无创痛临床样品(如尿液)检测进行常见疾病诊疗的可行性,为常见代谢病苯丙酮尿症的临床诊疗及新生儿代谢病的发生率和疾病谱的建立提供一种新方法、新技术。

英文摘要: To combine the high separation efficiency of Capillary Electrophoresis (CE) with the high sensitivity and good selectivity of Amperometric Detection (AD) and the universal of Capacitively Coupled Contactless Conductivity Detection (C4D), to develop a high-powered CE with double electrochemical detectors (CE-AD/C4D), to explore the rapid diagnoses of Phenylketonuria (PKU) representing inborn errors of amino acid metabolism and DNA oxidation damage, and the new methods for neonatal metabolic disease screening; to study the optimal conditions and anti-jamming capability for the analyses of the correlate mark compounds, and the distribution of mark compounds in the blood, urine, saliva and other body fluids, to explore the feasibility of diagnosis and treatment of common metabolic disease PKU by detecting no pain clinical samples (such as urine), to provide a new approach for the clinical diagnoses of common metabolic disease PKU and the establishment of neonatal metabolic disease incidence and diseases spectrum.
