摘 要:目的 通过对人卵巢上皮性肿瘤裸鼠原位移植瘤的癌旁组织相关蛋白的检测,探讨癌旁正常卵巢组织筛选的标准及冻融卵巢组织移植的可行性.方法 将人卵巢上皮性肿瘤OVCAR3细胞于裸小鼠颈背部近腋窝处皮下种植获取瘤源,行卵巢原位移植后,取癌组织、癌旁近端组织、癌旁中段组织、癌旁远端组织及正常裸鼠卵巢组织,采用流式细胞术检测各组织中的细胞角蛋白-7(CK-7)、CA125、p53、Survivin、基质金属蛋白酶-2(MMP-2)、金属蛋白酶组织抑制物-2(T1MP-2)的表达量;分别取全部指标阴性组、CK-7(-)CA125(-)Survivin(-)组、CK-7(+)CA125(+)Survivin(+)组的组织、癌组织和冻融正常裸鼠卵巢组织进行移植,分析各组移植后的癌变率及CA125水平变化,同时检测原位移植后不同病变程度的裸鼠血清CA125水平.结果 从52份人卵巢上皮性肿瘤裸鼠原位移植瘤模型中获取46份(88.5%)活组织检查正常的癌旁残余卵巢组织;仅卵巢种植裸鼠血清CA125水平高于正常裸鼠(P<0.01),低于卵巢外种植裸鼠(P<0.05).原位移植瘤组织中CK-7、CA125、p53、Survivin、MMP-2及TIMP-2的表达率分别为93.3 %(28/30)、93.3 %(28/30)、86.7%(26/30)、86.7%(26/30)、83.3%(25/30)、83.3%(25/30),癌旁近端组织的表达率分别为70.0%(21/30)、70.0%(21/30)、63.3%(19/30)、63.3%(19/30)、60.0%(18/30)、56.7%(17/30),癌旁中段组织的表达率分别为33.3%(10/30)、30.0%(9/30)、30.0%(9/30)、30.0%(9/30)、26.7%(8/30)、23.3%(7/30),癌旁远端组织的表达率分别为26.7%(8/30)、23.3%(7/30)、26.7%(8/30)、26.7 %(8/30)、30.0%(9/30)、30.0%(9/30);20份原位移植正常卵巢组织上述指标均为阴性.癌旁近端组织中CK-7、CA125、p53、Survivin、MMP-2及TIMP-2的表达率低于癌组织(P<0.05),高�Objective To investigate screening criteria of paraneoplastic normal ovarian tissue and the feasibility of human ovarian cryopreservation and transplantation in nude mice by detecting tumorassociated protein.Methods Human epithelial ovarian cancer cell line OVCAR3 were grown in subcutaneous tissue and the tumor tissues were orthotopic implanted.The expressions of CK-7,CA125,p53,Survivin,MMP-2 and TIMP-2 were detected by flow cytometry in tumor tissues,tissues of proximal,median and distal adjacent to tumor,as well as normal ovarian tissues of nude mice.The tissues of group with all negative iudicators,group with negative expressions of CK-7 CA125 Survivin,group with positive expressions of CK-7 CA125 Survivin,cancer tissues and normal ovarian tissues of nude mice were used for ovarian cryopreservation and transplantation.The carcinogenesis rate and CA125 level were analyzed in each group after transplantation.The CA125 level was also detected under different severities after orthotopic implantation in nude mice.Results 46 samples ovarian tissues with normal biopsy were gained from 52 cases of human epithelial ovarian cancer of orthotopic implantation model in nude mice.The CA125 level of only ovarian inoculation group was higher than those of control group (P 〈 0.01),and lower than those of outside ovarian inoculation group (P 〈 0.05).The expression rates of CK-7,CA125,p53,Survivin,MMP-2 and TIMP-2 in tumor tissues were 93.3 % (28/30),93.3 % (28/30),86.7 % (26/30),86.7 % (26/30),83.3 % (25/30),83.3 % (25/30) respectively.They were 70.0 % (21/30),70.0 % (21/30),63.3 % (19/30),63.3 % (19/30),60.0 % (18/30),56.7 % (17/30) in proximal tissues adjacent to tumor respectively,and they were 33.3 % (10/30),30.0 % (9/30),30.0 % (9/30),30.0 % (9/30),26.7 % (8/30),23.3 % (7/30) respectively in median tissues adjacent to tumor.In distal tissues adjacent to tumor were 26.7 % (8/30),23.3 % (7/30),26.7 % (8/30),26.7 % (8/30),30.0
