Typical specimen such as water and sediment of Suzhou creek, city particulate matter are collected and some results which have been obtained during the long term permanent operation of this project since 1998 are presented. Moreover, further aspects of environmental data evaluation and assessment are discussed.展开更多
目的:建立新疆肿瘤样本资源库质量控制体系。方法肿瘤标本收集、处理、保存按照《生物样本库最佳实践2012》第3版执行。标本每年进行1次质量检测,从标本库中按照1%比例随机抽取35例标本进行病理质检,确认取材部位与病理诊断符合情...目的:建立新疆肿瘤样本资源库质量控制体系。方法肿瘤标本收集、处理、保存按照《生物样本库最佳实践2012》第3版执行。标本每年进行1次质量检测,从标本库中按照1%比例随机抽取35例标本进行病理质检,确认取材部位与病理诊断符合情况;按照2%比例随机取样,2 a 检测标本120例,进行 RNA、DNA 和蛋白质分析。结果受检样本肿瘤部分均>86%,坏死组织面积均<10%,与术后病理检查结果复合率达97.1%。样本蛋白质和 DNA 无明显降解;RNA 电泳结果显示28 s 条带亮度为18 s 的1.5~2.0倍,标本 RNA 质控合格率为88.4%。结论新疆肿瘤标本资源库中的标本质量良好,可满足研究要求。展开更多
