摘　　要：目的　探讨尿路上皮特异蛋白Ⅱ (UPⅡ )基因表达与膀胱移行细胞癌血行转移及分期的关系。　方法　从 32例膀胱移行细胞癌患者静脉血及癌组织标本中提取RNA ,行RT PCR ,观察UPⅡ基因的表达。 2 0例其他肿瘤组织标本及 10例非肿瘤患者静脉血标本作为对照。　结果　 32例膀胱癌组织标本中均有UPⅡ基因表达。T1、T2 膀胱癌患者 19例 ,外周血中均无UPⅡ基因表达 ;T3 、T4膀胱癌患者 13例 ,外周血阳性表达 5例 (39% ) ,与T1、T2 患者相比差别有显著性意义 (P <0 .0 1) ,其中 2例转移 ,接受全身化疗后未再表达 ;2 0例其他肿瘤组织标本及 10例非肿瘤患者外周血标本中均未见UPⅡ基因表达。　结论　UPⅡ是尿路移行上皮特异标志之一。肿瘤分期高者外周血中可有UPⅡ表达 ;发生血行转移时UPⅡ基因可在患者外周血中表达。检测血中UPⅡ基因的表达可反映化疗疗效。Objective To investigate the expression of Uroplakin Ⅱ (UPⅡ) gene together with other conventional parameters in the patients with transitional cell carcinoma(TCC). Methods Total RNAs extracted from solid tumor tissues and blood samples of patients with TCC were reverse transcribed and subjected to polymerase chain reaction amplification (RT PCR).The products of RT PCR were analyzed by agarose gel electrophoresis. The expressions in solid tissues of other kinds of tumors and blood samples of non neoplasm patients served as controls. Results UPⅡ gene were expressed in all the solid tumor tissues of TCC(100%) and in the blood samples of 5 patients of T 3～T 4 neogrowth(39%), 2 of the 5 cases had hematogenous metastasis which became nondetectable after chemotherapy; UPⅡ gene has not been detected in the blood samples of T 1～T 2 TCC patients, the non neoplasm patients and other kinds of solid tumor tissues. Conclusions UPⅡ is one of the specific markers of urothelium.It can be found in TCC patients of stage T 3～T 4 and in patients with metastasis. The detection of UPⅡ in the blood sample might serve as a marker for chemotherapeutic efficacy.
