【摘要】:目的 探讨非酒精性脂肪性肝病(NAFLD)血液标本的采集和保存及生物样本库的建立和信息化管理方法。方法 收集2009年10月-2013年10月经B超及临床血液学检测诊断为NAFLD的1226例患者的全血标本,进行生化指标测定、血浆及全血基因组DNA提取,并检测DNA的浓度和纯度,分别放至-80 ℃超低温冰箱储存备用,同时建立一套信息管理系统用于NAFLD生物样本库的管理。结果 1226例NAFLD患者的全血标本,其中包括双生子标本83例及家系标本100例。血浆及DNA的提取成功率均为100%,并随机抽取100份DNA进行检测,结果表明所收集标本能够满足后续试验要求。结论 该研究成功建立了NAFLD生物样本库,拥有标准化的信息管理系统,对标本进行质量控制和信息化管理,为进一步研究NAFLD奠定了良好的基础。
【Abstract】:Objective To investigate the collection and preservation of blood specimens from patients with nonalcoholic fatty liver disease (NAFLD) and the establishment and information management of biobank. Methods Whole blood samples were collected from 1226 patients who were diagnosed with NAFLD based on B-mode ultrasound and blood tests from October 2009 to October 2013. Biochemical parameters were measured. Plasma and whole-blood genomic DNA was extracted from the samples, and the purity and concentration of DNA were determined. Specimens were preserved in a refrigerator (-80℃). An information management system for NAFLD biobank was established. Results Specimens of 1226 NAFLD patients, including those of 83 twins and 100 families, were collected. The success rate was 100% for extraction of plasma and whole-blood genomic DNA. One hundred DNA samples were randomly selected for testing, and the results showed that the collected specimens met the requirements of following experiments. Conclusion The NAFLD Biobank has been successfully established in this study. It has the standard information management system and enables the quality control and information management of specimens, laying a solid foundation for further research on NAFLD.
