目的 :通过对喉癌 /下咽癌、癌旁组织和慢性炎症粘膜及喉乳头状瘤和喉部炎性息肉标本进行端粒酶活性检测 ,探讨端粒酶在喉癌 /下咽癌发病机制中的重要作用。对端粒酶活性检测为喉或下咽部肿物的诊断和鉴别诊断提供新的指标和理论依据。方法 :采用非放射性端粒重复序列扩增法 (T
OBJECTIVE: To detect the telomerase activity of laryngeal / hypopharyngeal carcinoma, para-cancerous tissues and chronic inflammatory mucosa and laryngeal papilloma and laryngeal inflammatory polyp specimens to explore the role of telomerase in the pathogenesis of laryngeal carcinoma / hypopharyngeal carcinoma In the important role. The detection of telomerase activity for the diagnosis of throat or hypopharynx tumor diagnosis and differential diagnosis provide new indicators and theoretical basis. Methods: Non-radioactive telomere repeat amplification (T)
