我院人体组织生物样本库的建立和应用

目的 探讨人体组织生物样本库建设,标本收集、保存、质最控制、管理及应用等有关问题.方法 制定标准化操作流程,收取配套新鲜冷冻组织、石蜡包埋组织、全血、血清、血浆、脑脊液等标本,按不同要求处理分装,常规、液氮或-80℃超低温冰箱冷冻保存,应用数据库管理系统进行信息化管理.结果 从2004年9月至2008年9月共收集各类疾病标本504个病种,11872例33137管份,至今已向省内外提供新鲜冷冻组织标本2500例4360管,应用于DNA、RNA、蛋白提取及组织芯片、免疫组织化学等的相关性研究.结论 人体组织生物样本库的建立,有利于有效利用不可再生的人体组织标本资源,随时提供符合要求的良恶性疾病标本和正常对照标本;有利于探讨疾病的致病机制、开发疾病早期榆测新技术和新的治疗策略.

Establishment and application of human tissue biobank

Objective To explore issues of the human tissue biobank, ranging from its establishment, collection and preservation of samples, quality control, management and application. Methods Development of standardized operational procedures, collection of such samples as fresh frozen tissues from the surgery, paraffin-embedded tissues, whole blood, serum, plasma, and cerebrospinal fluid. Specimens were classified and made aliquots according to different requirements, and then stored at room temperature, -80℃ refrigerator or in liquid nitrogen. Microsoft Access database system was used in the management of these specimens. Results From September 2004 to September 2008, a total of 11 872 samples from patients with benign and malignant diseases were collected and preserved. Among them, 4360 tubes of fresh frozen tissue samples from 2500 cases were provided within and beyond the province. These samples were also applied to DNA, RNA, protein extraction and tissue microarray, and immunohistochemistry-related research. Conclusion Human tissue biobank is highly useful in sharing human tissue resources effectively, as it can provide high quality specimens from benign and malignant diseases and normal control. In addition, it plays a very important role in exploring pathogenesis, developing new technologies for early detection of disease and new therapeutic strategies.
