OBJECTIVETo investigate the relationship between the human papillomavirus (HPV) and esophageal carcinoma in Baoding City of Hebei Province.
METHODSWe detected HPV DNA in 42 formalin-fixed and paraffin-embedded tissues from surgically resected esophageal carcinomas from Baoding City of Hebei Province, by PCR with the general primer set of GP5 + /6 + for HPV L1 gene and type-specific primer sets for HPV16 and 18 as well.
RESULTS37 from 42 esophageal carcinoma samples were HPV positive and the rate was 88.1%. Among the samples detected, 19 were HPV16 E6 positive and rate was 45.2%, eight were HPV18 E6 positive and rate was 19.0%.
CONCLUSIONThe high rate of HPV in the esophageal carcinoma samples suggested that HPV plays an etiologic role in the development of esophageal cancer in Baoding City of Hebei Province.

OBJECTIVETo understand the distributions of DNA and neutralizing antibodies of human papillomavirus (HPV)16, 18 in 18-45 year-old women.
METHODSTotally, 1494 women were enrolled through multistage random sampling in Funing, Jiangsu province. Cervical exfoliated cells were collected from them for HPV DNA testing, and serum samples were taken from them for the detection of HPV16, 18 neutralizing antibodies by using pseudovirion-based neutralization assay(PBNA).
RESULTSAmong the 1494 women, 28(1.9%) and 188(12.6%) were positive for DNA and neutralizing antibody of HPV16 respectively, and 15(1.0%) and 60(4.0%) were positive for DNA and neutralizing antibody of HPV18, respectively. There were no significant differences in the detection rates of DNA and neutralizing antibody of HPV16, 18 among different age groups. About 16.7% of the women were infected with HPV16, 18, or both.
CONCLUSIONIn Funing county of Jiangsu province, most women aged 18-45 years has no immunity to HPV16 and 18, indicating that they are appropriate targets for HPV 16/18 vaccination.

Seborrheic keratosis (SK) is a benign epidermal tumor of unknown etiology. Because of its wart-like morphology, human papillomavirus (HPV) has been suggested as a possible causative agent. Viral involvement, however, has not been confirmed yet despite extensive research. The aim of this study was to evaluate the presence of HPV 6/11, 31, 33 DNA in nongenital SK. We analyzed 40 biopsy specimens taken from patients with nongenital SK using in situ polymerase chain reaction (PCR) and PCR with tissue extracts. The SK specimens (n=40), analyzed by in situ PCR, were negative for all HPV probes tested (types 6/11, 31, 33). Control slides (condyloma acuminatum, n=3) were positive for type 6/11, 31, and 33 HPV probes tested. Melasma samples (n=4), the negative controls, were consistently negative. No HPV DNA band was detected by PCR with the tissue extracts from paraffin-embedded SK samples, while condyloma acuminatum, the positive controls, showed DNA bands of the correct molecular weights. Our results show that HPV type 6/11, 31, and 33 cannot be recognized as causative agents for nongenital SK, which is in contrast to the previous studies. Further studies are required to reveal the presence of other types (more than 90) of HPV DNA.

Objective: To explore the effect of vaginal micro-environment alterations and HPV16 infection and their interaction in the progression of cervical intraepithelial neoplasia. Methods: The participants of this study came from the cervical lesions study cohort in Shanxi province, including 623 women with normal cervical (NC), 303 patients with pathogenically diagnosed low-grade cervical intraepithelial neoplasia (CINⅠ) and 93 patients with pathogenically diagnosed high-grade cervical intraepithelial neoplasia (CINⅡ/Ⅲ). The data of the demographic characteristics of the study subjects and factors related to cervical intraepithelial neoplasia were collected, and HPV16 infection were detected by using flow-through hybridization technology and H(2)O(2), β-glucuronidase, clotting enzyme, neuraminidase and leucocyte esterase in vaginal secretions were detected by using the combined detection kit of aerobic vaginitis and bacterial vaginosis. pH value and vaginal cleanliness were also detected at the same time. The database was established and analyzed by SPSS statistical software (version 22.0). Results: The HPV16 infection rate (trend χ(2)=55.45, P<0.001) and the abnormal rates of H(2)O(2) (trend χ(2)=26.19, P<0.001), pH (trend χ(2)=5.06, P=0.024), vaginal cleanliness (trend χ(2)=19.55, P<0.001), β-glucuronidase (trend χ(2)=17.52, P<0.001) and neuraminidase (trend χ(2)=14.90, P<0.001) increased gradually along with the severity of cervical intraepithelial neoplasia, but the abnormal rates of clotting enzyme and leucocyte esterase showed no same trend. The results of GMDR model analysis showed that there was interaction between HPV16 infection and abnormalities of H(2)O(2), β-glucuronidase, clotting enzyme and neuraminidase in CINⅠ group, and the interaction between HPV16 infection and the abnormalities of vaginal cleanliness, H(2)O(2), β-glucuronidase and neuraminidase in CIN Ⅱ/Ⅲ group. Conclusion: Our findings indicated that the vaginal micro-environment alterations and HPV16 infection could increase the risk of cervical intraepithelial neoplasia, and they might have an important synergistic effect in the progression of cervical intraepithelial neoplasia.

Further understanding of male human papillomavirus (HPV) infection is necessary to prevent infection in men, as well as transmission to women. In our current study, we investigated patterns of HPV infection and genotype distributions in male genital warts using the Anyplex II HPV28 Detection kit. We reviewed the medical records of 80 male patients who presented to 5 neighborhood clinics in Ulsan, Korea, for the treatment of genital warts between April 2014 and January 2015. All patients underwent HPV genotyping. The prevalence and characteristics of HPV infection were analyzed, and the patterns of HPV infection according to age were assessed. Among the study patients, 13 (16.3%) were negative for HPV infection, 46 (57.3%) were infected with low-risk HPV, and 21 (26.3%) were infected with high-risk HPV. Patients with multiple HPV infection were more likely to have high-risk HPV infection (P = 0.001). The prevalence of HPV infection was much higher in samples obtained by tissue excision due to a definite lesion (P = 0.001). There were no differences in high-risk HPV infection (P = 0.459), multiple HPV infection (P = 0.185), and recurrence at diagnosis (P = 0.178) according to age. HPV-6 and HPV-11 were the most common type overall (39.7% and 13.8%, respectively). HPV-16 and HPV-18 were the most common high-risk infections (both 3.4%). HPV infection is not only commonly encountered in male genital warts, but is also accompanied by high-risk HPV and multiple infections.

OBJECTIVETo evaluate the value of high-risk HPV (hrHPV) detection by Hybrid Capture II (HC2) in screening cervical intraepithelial neoplasm (CIN).
METHODSTotally 723 patients who had received a dual screening with thinprep cytologic test (TCT) and HC2 in our department were analyzed retrospectively. Among them, 350 patients received a triple examination with TCT, HC2, and colposcopic biopsy.
RESULTSAmong the 723 patients, the incidences of hrHPV infection with atypical squamous cell (ASC), low squamous intraepithelial lesion, and high squamous intraepithelial lesion were 70.7% (94/133), 88.9% (249/280), and 90.9% (90/99), respectively, significantly higher than 55.5% (117/211), the incidence of hrHPV infection with normal cytological results (P = 0.005, P < 0.001, P < 0.001, respectively). Among 350 cases who were received triple examination, the incidence of hrHPV infection with cervical intraepithelial neoplasia (CIN) 1 and CIN 2 were 88.9% (72/81) and 96.3% (52/54), significantly higher than 77.7% (153/197), the incidence of hrHPV infection with normal pathological results (P = 0.03, P = 0.002); The incidence of hrHPV infection with CIN 3 and squamous cancer were 91.7% (11/12) and 100.0% (6/6), also higher than normal cases. Among these 350 cases, the incidence of hrHPV infection with ASC was 79.3% (69/87). The incidence of CIN 2-3 with ASC and hrHPV infection was 38.0%, significantly higher than the incidence of CIN 2-3 with ASC and without hrHPV infection (5.9%) (P = 0.04).
CONCLUSIONhrHPV infection has a close relation with CIN, and the incidence of hrHPV infection increases along with the severity of CIN.
