目的 建立一个规范化、标准化的肝炎病毒（HBV）感染患者和对照组标本库。 方法 通过对四川绵阳地区大型流行病调查，收集HBV感染患者捐赠的血液标本（ELISA）检测调查者血样乙肝表面抗原（HBsAg），完整记录其实验报告，临床干预及流行病学调查资料。 结果 重大专项传染病综合防治四川示范区项目启动至今共收集血液组织标本87 478份，其中HBV检出阳性标本60 571份；保留相关阴性对照标本26 907份。 结论 建立HBV 感染患者及对照组血液标本库，可为乙肝的综合防治与研究提供高质量标本及相关流行病调查信息。
目的 依托四川大学华西医院的临床资源，建立了一个规范化、标准化的肿瘤组织标本库，对临床医学研究提供了珍贵的资源。 方法 于2009年6月创建四川大学华西医院肿瘤组织标本库、进行质量控制、规范化管理及总结实践经验。 结果 从创建肿瘤组织标本库至2012年2月，共收集各类肿瘤（胃、食管、肝、肺、肠、乳腺、胰腺、甲状腺、纵隔、肾脏、喉、脑）组织标本44 609例，包括肿瘤组织、肿瘤旁组织（距离肿瘤组织2 cm的组织）和切缘远端非肿瘤组织（距离肿瘤组织＞5 cm的组织）。对肿瘤组织标本进行有效和科学的管理，为科研提供了便利和高质量的资源。 结论 建立了一个国际标准化、规范化、信息完善的肿瘤组织标本库，可为肿瘤的发生、发展、转移及生物标志物的研究提供高质量的标本。
【Abstract】ObjectiveTo explore a rational and effective operative procedure of fresh tissue samples preservation for biliary tract carcinoma, and to establish a tissue bank with high quality, the authors had made a plan to store up the tissue samples of cholangiocarcinoma resected during operaion in deeplow temperature (cryopreservation), which is based on the clinical preponderance in the treatment of biliary tract diseases of the department of hepatobiliary surgery of General Hospital of P.L.A., and will be a good foundation for the systemic basic research of bile duct carcinoma. MethodsCases of biliary tract tumors confirmed by pathology were selected from the inpatients of Department of Hepatobiliary Surgery in General Hospital of P.L.A. from Jan. 2000 to June 2001. Fresh tissues were taken from the excised sample, which were stored in three different disinfectant tubes labelled cancer ( or tumor ) group, peritumor group and normal group. They were stored in liguid nitrogon container temporarily, and transferred into refrigerator for longtime storage as quickly as possible. The slices divided from the sample were grouped according to the dimensional space apart from the margin of tumor. Pathological diagnosis must be made on paraffin embedded samples. A part of the tissues was used to isolate total RNA by Trizol reagent for integrality judgment of it.ResultsTwentyone excised samples were stored including 4 intrahepatic bile duct carcinoma, 6 hepatic hilar cholangiocarcinoma, 7 extrahepatic bile duct carcinoma, and 4 duodenal ampulla carcinoma. The number and size of samples stored and duration of severance were not the same for reason of the difference of tumor volume, difficulty of operation and artificial jamming. The average duration was (47.60±43.87) min. The precipitated total RNA could be seen at the bottom of Eppendorf tube, of which the rate of A260/A280 was calculated about 1.6 to 1.8. It also could be seen in the 1%agarose gel electrophoresis for the obvious two bands of 28s and 18s, in which the28s band might be twofolds lighter than the 18s. Conclusion It is an important basic work for research of genes related to human disease to built a sample bank of human genetic resource. The present program for bile duct carcinoma tissue severance and storage is feasible and could supply the goodquality sample for further study. It must be reminded that the informed consent is needed and the left sample should be sufficient for postoperative pathological examination before the performance, which should be done by a fixed and experienced researcher group. Limitted to the operation of bile duct carcinoma, the time for beginning tissue severing should be in one hour after the sample excision, and samples should be divided into slices in short time to avoid decomposition of component during the following schedule.
