【摘要】 目的 :检测胸腔积液脱落细胞端粒酶活性 ,为临床鉴别诊断提供依据。 方法 :收集 10 4例癌性及结核性胸腔积液脱落细胞 ,用 TRAP- PCR- EL ISA法检测胸腔积液脱落细胞端粒酶活性。结果 :5 4例恶性胸腔积液脱落细胞端粒酶活性相对值为 0 .396± 0 .0 18,显著高于结核性胸腔积液组的 0 .0 0 3± .0 2 1(P<0 .0 1) ;端粒酶阳性检出率为 90 .9% (4 9/5 4) ,也显著高于结核性胸腔积液组 (6 .0 % ,3/5 0 ) (P<0 .0 1)。 结论 :癌性胸腔积液脱落细胞端粒酶活性显著增高 ,提示端粒酶活性检测可作为临床结核性与恶性胸腔积液鉴别诊断的参考依据之一更多还原

【Abstract】 Objective:To detect the activity of telomerase in pleural effusion, providing data for clinical diagnosis. Methods: The cells of tuberculous and cancerous pleural effusion were collected from 104 patients. TRAP PCR ELISA methods were used to detect the activity of telomerase. Results: The relative activity of telomerase in 54 cases of malignant pleural effusion (0.396±0.018) was obviously higher than that in the tuberculosis pleural effusion (0.003±0.021) ( P <0.01). The positive rate of telomerase detection was 90.9% (49/54), which was also higher than that in the tuberculosis pleutal effusion (6.0%, 3/50) ( P <0.01). Conclusion: The obvious increase of telomerase activity in the cancerous pleural effusion indicates that the detection of telomerase activity can be a marker for diagnosis of tuberculous and cancerous effusion.更多还原
