为了探讨人乳头瘤病毒（ｈｕｍａｎｐａｐｉｌｏｍａｖｉｒｕｓ，ＨＰＶ）１６、１８型及其与癌的关系，作者采用聚合酶链反应（ｐｏｌｙｍｅｒａｓｅｃｈａｉｎｒｅａｃｔｉｏｎ，ＰＣＲ）技术，检测２３例口腔鳞状细胞癌（ｏｒａｌｓｑｕａｍｏｕｓｃｅｌｃａｒｃｉｎｏｍａ，ＯＳＣＣ），正常口腔粘膜（ｎｏｒｍａｌｏｒａｌｍｕｃｏｓａ，ＮＯＭ）中的ＨＰＶ１６型和１８型ＤＮＡ中的Ｅ６、Ｅ７基因片段，并对其ＰＣＲ产物进行Ｓｏｕｔｈｅｒｎ印迹杂交分析，以研究ＨＰＶ与ＯＳＣＣ的关系。结果显示：ＯＳＣＣ中ＨＰＶＤＮＡ阳性率４７．８％（１１／２３），其中ＨＰＶ１６型６例，ＨＰＶ８型３例，ＨＰＶ１６和１８型复合感染２例，ＮＯＭ中ＨＰＶ阳性率２０％（２／１０），２例阳性者，均为ＨＰＶ１６型。研究结果提示：高危型ＨＰＶ与口腔鳞癌可能有关，二者的确切关系尚需进一步研究。但ＨＰＶ致癌基因Ｅ６、Ｅ７片段在口腔鳞癌中的检出，为鳞癌的病因研究开辟了新的前景
To investigate the relationship between human papillomavirus (HPV) types 16 and 18 and their relationship with cancer, the authors used polymerase chain reaction (PCR) to detect 23 cases of oral squamous cell carcinoma (OSCC) E6 and E7 gene fragments in HPV16 and 18 DNA in normaloral mucosa (NOM), and their PCR products were analyzed by Southern blotting to study the relationship between HPV and OSCC. The results showed that the positive rate of HPV DNA in OSCC was 47.8% (11/23), including 6 cases of HPV16, 3 cases of HPV8 and 2 cases of HPV16 and 18. The positive rate of HPV in NOM was 20% (2/10) , 2 were positive, are HPV16 type. The results suggest that: high-risk HPV and oral squamous cell carcinoma may be related to the exact relationship between the two needs further study. However, the detection of HPV oncogene E6 and E7 in oral squamous cell carcinoma has opened a new prospect for the etiology of squamous cell carcinoma
