摘要 目的建立我院生物样本库的样本质量控制体系。方法采用HE染色鉴定我院生物样本库肝癌、胃癌石蜡组织标本取材的准确性。对血凝块标本进行DNA的提取,经全自动核酸分析仪鉴定DNA的完整性。对冻存的肝癌、胃癌组织及其正常对照组织标本进行RNA、蛋白的提取,采用RT-PCR和Western blot的方法分别检测目的基因和蛋白的表达。结果 HE染色结果发现,所选组织的肿瘤部分占总组织的80%以上,为样本库的合格样本。血凝块样本的DNA提取后,经鉴定其完整性较好。在提取的冻存组织样本中都能检测到目的基因及蛋白的表达。结论经抽样检测,我院冻存标本的DNA、蛋白均没有明显的降解,保存质量较好。本研究标本质量鉴定方法简单、切实、可行,为今后我院组织样本质量控制体系的建立奠定基础。
