摘要

目的

建立一种简便快速的人乳头瘤病毒(human papillomavirus

HPV)DNA纸基提取方法并对其进行初步评价。

方法

以含HPV 16型基因片段的质粒为对象，结合紫外分光光度法和实时荧光定量PCR检测，对6种不同的纸材料进行选择，最终设计成方便拿取的浸蜡试纸条，对18例临床宫颈脱落细胞样本(阳性样本13例，阴性样本5例)进行HPV DNA提取检测，与常规煮沸法进行比较。

结果

1张核酸结合区面积为2 mm×10 mm的浸蜡定性滤纸条所提取的临床宫颈脱落细胞样本中的HPV DNA，经实时荧光定量PCR扩增，18例临床宫颈脱落细胞样本中的13例高危型HPV阳性样本均能成功检出，与常规煮沸法结果一致。每个样本提取时间

1 min，检出限为8×10

copies/mL，相对标准偏差为1.15%。

结论

建立的HPV DNA纸基快速提取方法无需移液、加热和离心等操作，洗脱液可直接作为PCR扩增反应的模板，极大简化了临床宫颈脱落细胞样本中HPV DNA的提取步骤。

Abstract

Objective

To establish a simple and rapid paper-based extraction method for human papilloma virus (HPV) DNA and to evaluate the method.

Methods

The plasmid containing HPV type 16 gene fragment was employed as the test subjects

and then 6 different paper materials were compared and selected by ultraviolet spectrophotometry and real-time fluorescence quantitative PCR (qPCR). Then

according to the efficiency of nucleic acid extraction and the optimal binding area

a convenient paper strip was designed. Finally

the designed paper strip was applied to extract HPV DNA from 18 clinical cervical exfoliated cell samples (13 positives and 5 negatives)

with its performance being evaluated after comparing with the conventional boiling method.

Results

The qualitative filter paper with a nucleic acid binding zone of 2 mm×10 mm could successfully extract HPV DNA from clinical cervical exfoliated cells. When this test strip was used for DNA extraction

all the 13 high-risk HPV positives were successfully detected out of the 18 clinical samples

which was consistent with the results of the conventional boiling method. In addition

the extraction time of the test strip was less than 1 min for each sample

with a detection limit of 8×10

copies/mL and relative standard deviation of 1.15%.

Conclusion

Our paper-based rapid extraction for HPV DNA does not require pipetting

heating and centrifugation

and the eluent can be directly used as the PCR template for amplification

which greatly simplifies the extraction process of HPV DNA from clinical cervical exfoliated cell samples.
