| serologic association between human papillomavirus type 16 infection and esophageal cancer in shaanxi province, china. | the existence of large geographic variations in the prevalence of esophageal cancer in some countries, such as china, indicates that environmental risk factors may be important in the development of this disease. some studies have implicated genital-mucosal strains of human papillomaviruses (hpvs) in the etiology of this cancer. | 1996 | 8841021 |
| the relationship between hpv16 and expression of cd44v6, nm23h1 in esophageal squamous cell carcinoma. | the esophageal squamous cell carcinoma (escc) has high incidence in shaanxi province of china. more and more researches indicated that human papillomavirus type 16 (hpv16) might play an important role in carcinogenesis of escc but the relationship between hpv16 and cd44v6, nm23h1 has not been elucidated. hpv16 was detected by amplifying hpv16 e6 gene through polymerase chain reaction (pcr) method and the expression of cd44v6, nm23h1 in 40 esccs and fifteen normal esophageal mucosa (nem) from sha ... | 2005 | 15645378 |
| [detection of human papilloma virus in esophageal squamous cell carcinoma and adjacent tissue specimens in linxian]. | a total of 87 human esophageal tissue specimens, comprising 35 squamous cell carcinomas and 52 adjacent tissue specimens (with no gross evidence of tumors) were obtained from patients who underwent surgery for cancer of the esophagus in lin-xian county, henen province. the tissue specimens were analyzed for the presence of hpv dna by southern blot assay with hpv type 16 and 18 probes and by polymerase chain reaction (pcr) with hpv consensus primer. the esophageal epithelial specimens of human fe ... | 1995 | 8697965 |
| prevalence of high-risk human papillomavirus infection among women in shaanxi province of china: a hospital-based investigation. | this study aimed to investigate the characteristics of female high-risk human papillomavirus (hr-hpv) infection in shaanxi province of china. a total of 14 111 women were enrolled for hpv genotyping test, and a cytology, and/or cervix biopsy were performed in partial women. of these women, the hpv infection rate was 30.21%, and 26.73% were caused by hr-hpv. the most common hr-hpv genotypes were hpv-16, hpv-58, hpv-52, hpv-18, and hpv-31. the prevalence of hr-hpv among women older than 50 years w ... | 2016 | 27935120 |
