摘　　要：目的建立一种通用型含内源性内参的重组酶介导的等温扩增技术(EIC-RAA)检测人乳头瘤病毒6型(HPV-6)和11型(HPV-11)的方法,以实现HPV-6和HPV-11的简单、准确、快速筛查。方法针对HPV-6和HPV-11的L1片段保守区域设计通用型引物和探针并结合核糖核酸酶P(RNaseP)基因引物和探针作为内参建立了检测HPV-6和HPV-11的EIC-RAA方法;用系列浓度稀释的质粒和不同亚型HPV样本核酸检验其灵敏度、重复性和特异度;收集的230份临床样本进行EIC-RAA和商业化HPV PCR-荧光探针法检测,并对结果进行比较。结果建立的EIC-RAA方法可在39℃条件下30min内实现HPV-6和HPV-11的检测,其灵敏度为10copies/reaction,重复性好,特异度高,EIC-RAA检测结果与商业化HPV PCR-荧光探针法检测结果的符合率为100%。结论建立了一种检测HPV-6和HPV-11的EIC-RAA方法,该检测方法具有简单、准确、快速的优点,在HPV-6和HPV-11的筛查中具有潜在的应用价值。Objective To establish a universal endogenous internally controlled recombinase-aided amplification(EIC-RAA)for the detection of HPV-6 and HPV-11 method,in order to achieve simple,accurate and rapid screening of HPV-6 and HPV-11.Method The EIC-RAA method for detecting HPV-6 and HPV-11 was established by designing universal primers and probes for L1 fragment of the conserved region of HPV-6 and HPV-11,and combining RNaseP gene primers and probes as internal reference.The sensitivity,repeatability and specificity of EIC-RAA method were tested by series of concentration diluted plasmids and nucleic acids from different subtypes of HPV sample.A total of 230 clinical samples were collected and compared for EIC-RAA and commercial HPV PCR-fluorescent probe method.Result The established EIC-RAA method can detect HPV-6 and HPV-11 within 30 minutes at 39℃,with a sensitivity of 10 copies/reaction,good repeatability and high specificity.The coincidence rate between EIC-RAA and commercial HPV PCR-fluorescent probe method was 100%.Conclusion The EIC-RAA showed the advantages of simplicity,accuracy and rapidity in detecting HPV-6 and HPV-11,and has great potential application value in the field screening of HPV-6 and HPV-11.
