中文摘要:
      目的:检测miR-19b 与miR-20a 在非小细胞肺癌(NSCLC)组织中的表达,探讨两者与肺癌临床病理的关系。方法:选择我院 NSCLC 肺癌患者50 例,使用Real-time RT-PCR 法对其癌组织及癌旁正常组织中miR-19b 和miR-20a 的含量进行检测,并利用2 (-△△CT)法处理结果,分析与临床病理资料的关系。结果:相对于内参U6,miR-19b 基因在NSCLC 组织中的表达量明显低于癌 旁正常组织,而miR-20a 基因在NSCLC 组织中的表达量明显高于癌旁正常组织,差异具有统计学意义(P<0.05);在NSCLC 组织 标本中,miR-19b 基因表达量在临床分期I-II的标本中明显高于临床分期III,而miR-20a 基因表达量在临床分期I-II的标本中明 显低于临床分期III,差异均就有统计学意义(P<0.05);miR-19b 基因表达量在肿瘤病理低分化组织中明显低于肿瘤病理高分化组 织,而miR-20a 基因表达量在肿瘤病理低分化组织中明显高于肿瘤病理高分化组织,差异均具有统计学意义(均P<0.05)。结论: miR-19b 低表达和miR-20a高表达与NSCLC 的临床分期、病理分级具有密切关系,早期检测有助于NSCLC诊断和治疗。
英文摘要:
      Objective:To detect the expressions of miR-19b and miR-20a in the tissues of non-small cell lung cancer (NSCLC) and to explore the relationships between the expressions of miR-19b and miR-20a and the pathology.Methods:50 patients with NSCLC in our hospital were selected, and 2(-△△CT) method was used for quantitative analysis on the relationships of the expressions of miR-19b and miR-20a in the tissues of the carcinoma and the adjacent normal lung with the pathological characteristics.Results:With the reference of U6, the expression of miR-19b in NSCLC tissues was lower than that of the adjacent normal tissues, while the expression of miR-20a in NSCLC tissues was higher than that of the adjacent normal tissues, and the differences were statistically significant (P<0. 05); the expression of miR-19b in the I-II clinical stage was higher than that of the III, while the expression of miR-20a in the I-II clinical stage was lower than that of the III, and the differences were statistically significant (P<0.05); the expression of miR-19b in the low pathological grade was lower than that of the high pathological grade, while the expression of miR-20a was higher, and the differences were statistically significant (P<0.05).Conclusion:It is indicated that the low expression of miR-19b and the high expression of miR-20a should be closely related to the clinical stages and the pathological types of NSCLC, which would be helpful to the diagnosis and treatment of NSCLC by early detection.
