荧光定量PCR检测在宫颈癌筛查中的应用

目的探讨荧光定量聚合酶链反应(FQ-PCR)检测宫颈病变人乳头瘤病毒(HPV)13种高危型DNA的可行性,为检测宫颈组织中HPV的感染提供有效的方法。方法选择197例阴道细胞学检测异常的宫颈脱落细胞,使用FQ-PCR方法检测13种高危型HPV DNA,同时取宫颈病变处组织进行组织病理学检查。结果 329例样本中HPV 13种高危型阳性者218例,阳性率为66.26%:CT值范围在13～40之间,平均为(26±2.31);组织病理学检测186例阳性,阳性率为56.53%,经χ~2检验,差异有统计学意义(χ~2=6.566,P=0.0104);阴性标本为Undet。结论 FQ-PCR方法检测宫颈病变中13种高危型HPV DNA感染,具有快速、简便、灵敏度高、特异性强等优点,对宫颈癌的普查和治疗有指导意义。     

杂交捕获法和PCR-RDB法检测妇女HPV感染的比较

目的探讨HC2法和PCR-RDB法检测妇女HPV感染的异同点。方法利用HC2法和PCR—RDB法检测妇女生殖道HPV感染状况，然后进行比较。结果81．14％（400／493）的样本PCR-RDB法和HC2法检测结果一致，两法一致性检验Kappa值为0．63（95％CI，0．57～0．69）。在HC2法RLU／CO〈1．00、1．00～9．99、10．00～99．99、100．00～999．99和≥1000．00的样本中，PCR—RDB法13种高危型HPV的检出率依次为1．60％（3／187）、29．85％（20／67）、69．88％（58／83）、86．52％（77／89）和91．04％（61／67），五组间比较，差异有统计学意义（Х^2=289．3，P〈0．01）。HC2法高危型HPV试剂可与HPV53、66、11、cp8304等基因型发生交叉反应。结论HC2法和PCR-RDB法具有较好的一致性，HC2法存在交叉反应现象，PCR-RDB法难以标准化。     

TCT及高危HPV DNA检测对宫颈病变筛查的意义

目的探讨薄层液基细胞学检查(TCT)和高危人乳头瘤状病毒DNA(HR-HPVDNA)检测对宫颈病变筛查的意义。方法对常州市第二人民医院妇科门诊1235例妇科患者做TCT检查,对TCT检查结果异常的患者进一步做HR-HPVDNA检测。结果 1235例患者中TCT检查结果异常者有113例,占9.15%,其中不典型鳞状细胞和腺细胞病变(ASCUS)44例(3.56%),低度鳞状上皮内病变(LSIL)35例(2.83%),高度鳞状上皮内病变(HSIL)29例(2.35%),鳞状上皮细胞癌(SCC)5例(0.40%)。113例TCT检查异常者HR-HPVDNA检测阳性61例,阳性率53.98%;HR-HPVDNA阳性率分布为:ASCUS36.36%(16/44)、LSIL54.29%(19/35)、HSIL72.41%(21/29)、SCCl00.00%(5/5),阳性率随宫颈病变级别升高而升高。结论 TCT和HR-HPVDNA检查是筛查宫颈癌前病变的有效方法,两者结合有利于提高宫颈癌及癌前病变的检出率。     

杂交捕获法和PCR-RDB法检测妇女HPV感染的比较

Objective To compare hybrid capture-Ⅱ(HC2)to polymerase chain reaction(PCR)-reverse dot-blot(RDB)for detecting HPV infection in women.Methods HC2 method and PCR-RDB were applied to detecting human papillomaviral infection in female genital duct,and the test results were analyzed.Results Concordant results were found in 81.14%(400/493)samples(Kappa=0.63;95%CI,0.57-0.69).The high risk type HPV positive rate detected by PCR-RDB were 1.60%(3/187),29.85%(20/67),69.88%(58/83),86.52%(77/89)and 91.04%(61/67),respectively,when the HC2 RLU/CO of samples were＜1.00,1.00-9.99,10.00-99.99,100.00-999.99 and≥1000.00.Statistical differences were found among the five groups(χ2=289.3,P＜0.01).Cross reactions were found between HC2 high risk probe and HPV53,66,11,cp8304 and other genotypes.Conclusion There is good concordance between HC2 and PCR-RDB,though cross reaction exists in HC2.Relatively speaking,there are more influential factors for PCR-RDB.
