miRNA-192在骨肉瘤临床样本中的表达及与各临床要素之间关系的相关研究

Research on Expression of miRNA-192 in Human Osteosarcoma and the Relationship between It and Clinicopathological Features

目的:观察miRNA-192在骨肉瘤中与各临床要素之间的关联,分析其与骨肉瘤患者生存情况之间的关系,为研究miRNA-192在骨肉瘤中的作用及可能的临床应用提供理论依据。方法:选取50例骨肉瘤新鲜样本组织及瘤旁组织,使用荧光RT-PCR的方法对样本中的miRNA-192的含量进行检测,结合详实的随访资料,分析miRNA-192与性别、年龄等临床要素之间的关系。通过生存分析的方法,分析miRNA-192与患者生存情况之间的关系。结果:miRNA-192与患者的年龄,肿瘤大小,分期,生存时间等有明显的统计学关联(P<0.05),包括年龄(P=0.028),临床分期(P=0.007),远端转移(P=0.013)和生存率(P=0.001)。结论:在临床样本中,miRNA-192与患者的多项临床要素有显著性关联,包括年龄,临床分期,远端转移和生存率,为接下来关于miRNA-192在骨肉瘤中的各项研究,特别是作为生物标记信号的临床应用奠定了良好的实验基础。

Objective： To explore and describe the relationship of miRNA-192 function and clinicopathological features in human osteosarcoma and analyze the relationship between miRNA-192 and mortality, which support some theoretical basis for osteosarcoma treatment and element experience for further research. Methods： Real-time quantitative PCR analysis were used in 50 clinical osteosarcoma samples which were followed up. Then the relationship of miRNA-192 function and clinicopathological features（like sex,age） in human osteosarcoma were explored. Results： We found that there were statistically significant relationships between miRNA-192 expression and some clinicopathological features of osteosarcoma, including age（P = 0.028）, clinical stage（P = 0.007）, distant metastasis（P = 0.013） and patient mortality（P=0.001）. Conclusion： In clinical specimens, miRNA-192 expression levels were correlated with some clinicopathological features of osteosarcoma, including age, clinical stage, distant metastasis and patient mortality, which provided the theoretical basis for the next study especially the biological therapy of miRNA-192 in the osteosarcoma.
