摘要
目的:探讨间接酶联免疫吸附试验(ELISA)检测核糖核酸酶抑制因子(RI)在恶性肿瘤患者血清中的表达。方法:建立检测血清RI含量的间接ELISA法,检测和比较正常人、恶性肿瘤患者(乳腺癌、胃癌、肺癌、肝癌)、乳腺良性肿瘤患者血清中RI的表达水平。结果:所建立的间接ELISA法特异性高;恶性肿瘤患者血清中RI表达均明显低于正常人(P<0.05),乳腺癌亦明显低于乳腺良性肿瘤(P<0.05)。结论:RI表达的降低可以作为肿瘤良、恶性鉴别的指标之一。
Objective: To detect the expression of ribonuclease inhibitor (RI) in the serum of patients with malignant tumors by indirect ELISA. Methods:The indirect ELISA method was established to detect the expression of RI in the serum of patients with malignant tumors, including breast cancer,gastric cancer,lung cancer,and liver cancer,patients with benign breast tumor,and normal controls. Results:The specificity of the indirect ELISA was high in the detection of the expression of RI. The expression of RI in patients with malignant tumors was significantly lower than that in normal controls. Conclusion:The indirect ELISA is a specific method for detecting the expression of RI,and the expression of RI may be used in the differential diagnosis of malignant and benign tumors.
