Methods: During the April 2003 to December 2004, from the patients with different position colorectal cancer beyond Dukes C stage who were performed laparoscopic radical operation random draw 20 patients as experiment group, and from patients with different position colorectal cancer beyond Dukes C patients who were performed open radical operation 20 patients took randomly as contrast group. We draw thepatients blood about 5 ml from antecubital vein at the time before and after the operation about 30 minutes respectively, preserved the blood in deep hypothermia circumstance,cytrokeratin-20(CK-20) as the micrometastasis maker, using the RT-PCR technique,G3PDH as the intra-contrast gene, quantitatively detect the amounts of CK-20 in the blood with the gelatum imagery system and the computer analyzing software on the gelatum imagery system ,in order to compare the influence of the laparoscopic and the open operation on the micrometastasis.

在我院2003年4月—2004年12月间不同部位的临床分期在Dukes C期之内的接受了腹腔镜结直肠癌根治术结直肠癌患者中随机抽取20例作为试验组，另外在同期的接受开腹手术患者中随机抽取20例作为对照组，分别抽取术前30min和术后30min的肘前静脉血5ml，集中低温保存，以细胞角蛋白(cytekeratin-20)CK-20为微转移的标志物，应用RT-PCR技术，以G3PDH为内对照基因，应用凝胶成像系统及其计算机凝胶成像系统分析软件来定量检测手术前、后患者外周静脉血中CK-20含量，比较腹腔镜和开腹的手术方式对肿瘤微转移的影响。

1,After transfected the mutated mtDNA of colorectal carcinoma,the mtDNA D-loop region of the transfected cells displays new mutation points.2,The external source pieces of the mutated mtDNA can integrate to nuclear genome after transfection.3,There's no differences in apoptosis between combinations after transfected the mutation of mtDNA in NIH3T3 and LST cells.4,The mutated mtDNA may affect the action mechanism of occurrence and development in colorectal carcinoma through affecting its mtDNA mutation or integrating exogenetic mtDNA to its nuclear which may cause the abnormal expression of oncogene or anti-oncogene.

（1）转染突变的大肠癌细胞mtDNA后转染细胞的mtDNA均可发生多处的突变位点。（2）通过转染后突变的外源性的mtDNA可以整合到核基因组内。（3）突变的mtDNA转染LST细胞及NIH3T3细胞后，不影响转染细胞的凋亡改变。（4）mtDNA的突变可能通过影响体细胞mtDNA的突变和通过外源性mtDNA在核内的整合从而影响癌基因或抑癌基因的表达异常，从而参与肿瘤的发生发展。
