人乳头瘤病毒、端粒酶基因及3号染色体数目与宫颈病变关系的探讨

目的探讨人端粒酶(TERC)基因的表达和人乳头瘤病毒(HPV)感染及3号染色体数目突变与宫颈病变的关系。方法 2008年6月至2009年2月昆明医学院第二附属医院妇科门诊接受诊治者共81例,其中健康组(病检结果正常)20例,子宫颈上皮非典型增生(CIN)1组28例,CIN2组12例,CIN3组9例,宫颈癌组12例。采用荧光原位杂交技术(FISH)进行子宫颈上皮脱落细胞TERC基因的检测,同时利用实时荧光定量聚合酶链反应(FQPCR)技术检测这81例受试者的HPV感染情况。并进行宫颈癌与TERC基因和HPV的相关性分析。同时记录81例受试者3号染色体数目突变情况。结果在宫颈病变检测中TERC基因检测和HPV检测阳性率差异无统计学意义(P0.05),二者阳性率在CIN1组、CIN2组、CIN3组和宫颈癌组均明显高于健康组(P0.05),CIN1组与CIN2组差异无统计学意义(P0.05),CIN3组与宫颈癌组差异有统计学意义(P0.05),恶性程度越高,二者阳性率越高。健康组和CIN1组3号染色体数目异常突变率为0%;CIN2组为16.7%;CIN3组为66.7%;宫颈癌组为100.0%,CIN3组和宫颈癌组阳性率明显高于健康组、CIN1组CIN2组,差异有统计学意义(P0.05)。结论在宫颈癌的发生、发展过程中TERC基因异常表达、高危HPV感染、3号染色体数目的突变可能起着重要的协同作用。

Study on relationship between human papilloma virus,telomerase gene and chromosome 3 number with cervical lesions

Objective To explore the relationship between the expression of human telomerase RNA component (TERC) gene , human papilloma virus (HPV) infection and mutation of chromosome 3 number with cervical lesions .Methods 81 women received the treatment in the Gynecology Department of the Second Affiliated Hospital of Kunming Medical University from June 2008 to February 2009 ,including the healthy group(normal pathological examination ,20 cases) ,CIN1 group(28 cases) ,CIN2 group(12 ca‐ses) ,CIN3 group(9 cases) and cervical cancer group(12 cases) .The TERC gene expression in uterine epithelial exfoliated cells was detected by using the fluorescence in situ hybridization (FISH) method ,meanwhile the HPV infection was detected by using the real time fluorescence quantitative polymerase chain reaction (FQPCR) technology .The correlation between cervical cancer with TERC gene and HPV was analyzed .At the same time the number of chromosome 3 mutations in 81 cases was recorded .Results In the cervical lesion detection ,the detection positive rate had no statistical difference between the TERC gene detection and HPV detec ‐tion (P> 0 .05) ,their positive rates in the CIN 1 ,CIN2 ,CIN3 and cervical cancer groups were significantly higher than that in the healthy group (P< 0 .05) ,the difference between the CIN1 group and the CIN2 group had no statistical significance (P > 0 .05) , while between the CIN3 group and the cervical cancer group had statistical significance (P< 0 .05) ,the higher the malignant degree , the higher the positive rate .The abnormal mutation rate of chromosome 3 number was 0% in the healthy group and the CIN1 group ,16 .7% in the CIN2 group ,66 .7% in the CIN3 group and 100 .0% in the cervical cancer group ,the positive rate in the CIN3 group and the cervical cancer group was significantly higher than that in the healthy group ,CIN1 group and CIN2 group ,the differ‐ences were statistically significant (P< 0 .05) .Conclusion The TERC abnormal gene expression ,high risk HPV infection and mutation of chromosome 3 number could play an important synergistic effect during the process of occurrence and progression of cervical cancer .
