【摘要】 目的　探讨用免疫印迹发光法 ,检测乳腺肿瘤患者血清细胞质胸苷激酶 (TK1)的研究及临床应用。方法　利用抗胸苷激酶单克隆抗体 (anti TK1mAb)建立点免疫印迹发光法 ,分析乳腺肿瘤患者、非肿瘤患者和体检健康者血清TK1的水平。结果　术前的乳腺癌患者、乳腺良性肿瘤患者、非肿瘤患者和体检健康者血清TK1的水平分别为 (39.3± 33.9) ,(3.7± 3.9) ,(1.7± 0 .5 )和 (1.4±0 .5 )pmol/L。淋巴结转移的术前和术后乳腺癌患者、乳腺良性肿瘤患者血清TK1与体检健康者差异有显著意义 (P <0 .0 0 1,P <0 .0 0 1,P <0 .0 5 ) ;而淋巴结未转移的术后乳腺癌患者、非肿瘤患者血清TK1与体检健康者差异无显著意义 (P >0 .10 ,P >0 .0 5 )。通过对术后乳腺癌患者血清TK1检测发现 ,淋巴结未转移患者TK1水平明显低于淋巴结转移患者 (P <0 .0 0 1)。结论　该方法有较好的敏感性与特异性 ,用于血清TK1的检测可作为乳腺癌的辅助诊断、术后疗效观察和预后判断的方法之一更多还原

【Abstract】 Objective To evaluate the value of immunoblotting in the detection of serum thymidine kinase 1 (TK1) in breast tumor patients. Methods TK1 in sera from breast tumor patients, non tumor patients and healthy volunteers were determined with immunoblotting assay.Results The levels of TK1 in breast cancer patients before operation, patients with benign breast tumor, non tumor patients, and healthy volunteers were (39.3± 33.9), (3.7±3.9), (1.7±0.5) and (1.4±0.5) pmol/L respectively. The value of TK1 was higher in malignant and benign breast neoplasms patients than in healthy volunteers. However, no significant difference in the TK1 level was found between breast cancer patients without metastasis after operation, non tumor patients, and healthy volunteers.Conclusions The immunoblotting of TK1 by anti TK1 antibody is a sensitive and specific assay. It can be used to monitor and predict the efficiency of the therapy as well as the breast neoplasms progression during clinical course.更多还原
