The prevalence of human papilloma virus (HPV)-16 in patients with cervical cancer,the physical status of HPV-16 in patients with cervical lesions,and the role of HPV-16 integration in cervi-cal carcinogenesis were investigated.HPV genotyping was performed by using PCR approach with the primer GP5+/GP6+ and type-specific primer on biopsy specimens taken operatively from 198 women.Multiple PCR was done to detect physical status of HPV-16 in a series of cervical liquid-based cytology samples and biopsy specimens obtained from different cervical lesions with HPV-16 infection,includ-ing 112 specimens with cervical cancer,151 specimens with CINⅠ,246 specimens with CINⅡ and 120 specimens with CINⅢ.The results showed that there were 112 cervical cancer samples (56.57% of total cervical cancer patients) with HPV-16 infection.The frequency of HPV-16 pure integration was 65.18% (73/112),56.57% (47/120),23.58% (58/246) and 7.95% (12/151) in cervical cancer,CINⅢ,CINⅡand CINⅠ patients respectively.In situ hybridization was performed on some paraffin-embedded sections of CINⅡ,CINⅢ and cervical cancer to verify the physical status of HPV-16 infection.Sig-nificant difference was observed between cervical cancer and CINⅠ,CINⅡ,CINⅢ in the frequency of HPV-16 integration (P<0.01).It is suggested that HPV-16 is the most prevalent type and is associated with cervical cancer.In the case of HPV-16 infection there are close associations between the severity of cervical lesions and the frequency of HPV-16 integration.The application of testing HPV genotyping and physical status based on detection of HC-Ⅱ HPV DNA would be in favor of predicting the progno-sis of cervical precancerosis and enhancing the screening accuracy of cervical cancer.  相似文献

Background Human papillomavirus (HPV) is believed to be the most common sexually transmitted infection. However,little is known about the prevalence and distribution of HPV types in China. We aimed to assess the prevalence and the distribution of HPV types as well as risks for abnormal cervical cytology in women who reside in the Tibetan Autonomous Region of China.Methods A cross-sectional study was performed involving a sample of 3036 women. An epidemiological questionnaire was applied and cervical specimens were obtained for liquid-based cytology and HPV DNA detection. Statistical analysis included chi-square and Logistic regression model.Results In this population, 3.66% (111/3036) had atypical squamous cells of undetermined significance (ASCUS),1.45% (44/3036) low-grade squamous intraepithelial lesions (LSIL) and 1.09% (33/3036) had high-grade squamous intraepithelial lesions (HSIL). Tibetan women (5.74%, 137/2387) exhibited lower abnormal cytology rates than non-Tibetan women (8.01%, 52/649, P=0.03). The overall prevalence of HPV infection was 9.19% (279/3036). We failed to identify any differences in HPV prevalence by age. In the groups with normal, ASCUS, LSIL and HSIL, the overall HPV prevalences were 7.41% (211/2847), 24.32% (27/111), 56.82% (25/44) and 45.45% (15/33), respectively. HPV 16 (1.52%,46/3036) was the most common type, and was also the most prevalent in women with ASCUS (8.11%, 9/111) and HSIL (15.15%, 5/33). The most common HPV type for Tibetan women was HPV 16 (1.42%, 34/2387), whereas for non-Tibetan individuals it was HPV 33 (2.31%, 15/649). Of the 279 HPV-infected women, 40 individuals (14.34%) presented with multiple HPV positivity. Women who had two pregnancies were more likely to have abnormal cytology smear (OR=1.67;95% CI: 1.07-2.61).Conclusions A low prevalence of HPV positivity was observed in women who reside in the Tibetan Autonomous Region of China. The prevalence of abnormal cervical cytology and HPV type distributions were different between Tibetan and non-Tibetan women.  相似文献

Summary: To investigate the reliability and feasibility of human papillomavirus (HPV) DNA test in cervical scraping smears with polymerase chain reaction (PCR), 131 cases of cervical scraping specimens were collected, and the positive rates and accuracy of HPV infection were determined in normal subjects and cervical cancer patients. GP5^+/GP6^+ and E7 primer pairs designed for detecting HPV L1 and HPV type 16 E7 were tested in this study. Our results showed that positive rates of HPV DNA in normal population and cervical cancer patients were 32.99% and 73.53% respectively and there was significant difference between them (P〈0. 001). In normal subjects, detection rates of HPV DNA with GP5^+/GP6^+ and E7 primer pairs were 27.84 % and 16.49 % respectively, with statistically significant difference between them (P〉0.05). However the detection rates in cervical cancer patients were 38.24 % and 67.65 % for the two markers, with a significant difference found between them (P〈0.05). It is concluded that HPV DNA test with PCR for cervical scraping smears was feasible. GP5^+/GP6^+ primer pairs may be a useful probe to screen HPV infection in normal population, but they are not sensitive enough in cervical cancer patients. It is suggested that high risk type HPV DNA test was very useful in population with high risk of cervical cancer.  相似文献

This study investigated the expression and prognostic value of SHP-2 in cervical cancer caused by human papillomavirus (HPV) infection. Forty-five specimens from patients with cervical can-cer (stageⅠ-Ⅲ), 32 specimens from patients with cervical intraepithelial neoplasia (CIN) (Ⅰ, Ⅱ) and 20 normal cervical samples from patients with hysteromyoma were collected in Department of Pathol-ogy for comparison. The expression levels of SHP-2 and IFN-β proteins were detected by using immu-nohistochemistry. The mRNA expression level of SHP-2 was detected by using quantitative real-time polymerase chain reaction (PCR). HPVs were detected by HPV GenoArray Test. The Spearman corre-lation was used to compare the expression level of SHP-2 in HPV infected cervical cancer vs non-HPV infected normal cervix. The level of SHP-2 protein expression in the cancer tissues (88.8%) was sig-nificantly higher than in CIN tissues (62.5%) and normal cervixes (45%) (P<0.05 and P<0.05, respec-tively). The SHP-2 mRNA levels in the cancer tissues were upregulated as compared with those in the normal cervixes (P<0.05). Twenty-one (46.7%) cervical cancers, 25 (78.1%) CINs and 17 (85%) normal cervixes showed IFN-β positive staining in cytoplasm. There was statistically significant difference in the expression rate of IFN-β between cervical cancer and normal cervix (χ2=8.378, P<0.05) as well as between cervical cancer and CIN (χ2=7.695, P<0.05). HPV16/18 infections could be found in normal cervixs (15%), CINs (68.7%) and cervical cancers (84.4%). There was a correlation between HPV in-fection and SHP-2 expression in cervical cancer (rs=0.653, P<0.05). SHP-2 may be a useful prognostic and diagnostic indicator for HPV infected cervical cancer. In cervical cancers, SHP-2 mRNA and pro-tein overexpression was associated with IFN-β lower-expression.  相似文献

Background  Vaginal intraepithelial neoplasia (VAIN), as a precursor of vaginal cancer, is a rare disease. Its prevalence has not been well analyzed. This research is to ascertain the risk factors for VAIN in a Chinese population.
Methods  A case-control study was conducted, including 63 VAIN cases and 64healthy controls. In all subjects Pap smear and HPV tests were performed. A questionnaire survey was distributed, covering information on socio-demographic characteristics, smoking, past history, reproductive and sexual histories. The clinical pathological data were collected from medical records including symptoms, Pap smear results, grade of lesions, and human papillomavirus (HPV) status.
Results  Postmenopausal women had a 2.09 times higher risk for VAIN than pre-menopausal women (95% CI: 1.10–3.85; P=0.024). The patients with previous hysterectomy had an increased risk of VAIN (OR=4.69; P=0.003). Patients with a history of cervical cancer or CIN were predisposed to VAIN (OR=78.75; P <0.0001). The rate of HPV infection in VAIN was significantly higher than in controls, and an increased risk of VAIN was observed in patients with higher viral load (OR=126.00; P=0.000). Multivariate analysis showed that HPV infection and a history of CIN or cervical cancer were still found to be significant in patients.
Conclusion  HPV infection and a history of CIN or cervical cancer are the main risk factors for the development of VAIN.

Objective To determine the incidence of infection with HPV and the distribution of HPV genotypes on patients with Condyloma acuminatum. Methods Twenty-three different HPV types were detected by PCR and reverse dot blot (RDB) hybridization over all 6 508 samples of vulva and cervix uteri in patients with condyloma acuminatum. Including 18 types were high-risk (HR)-HPV (16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 83 and MM4), and 5 types were low-risk (LR)-HPV (6, 11, 42, 43 and 44). Results Among 6 508 cases, there were 3 288 cases with HPV infection and the incidence rate was 50.52%. The positive HPV patients overlap all 23 genotypes detected. There were 2 038 cases infected with a single HPV type and 1 250 cases infected with multiple HPV types. The constituent ratios in positive cases were 61.98% and 38.02%, respectively. There were 1 453 cases only with LR-HPV types infection, 945 cases only with HR-HPV types and 890 cases both with LR-HPV and HR-HPV infection, and the constituent ratios were 44.19%, 28.74% and 27.07%. There were 4 843 times positive HPV infection, including HR-HPV 2 361 times and LR-HPV 2 482 times. The common HR-HPV genotypes were 16, 52, 58, 56, 18, 66 and 33, and the incidence ratios were 6.31%, 5.06%, 4.04%, 2.60%, 2.41%, 2.40% and 2.28%. And the common LR-HPV genotypes were 6, 11 and 43, and the incidence ratios were 16.98%,11.09% and 6.75%, respectively. Overlap 23 types, the most common geno- types were HPV6 and HPVll, the incidence rates were higher than others (P〈0.05). Conclusion HPV infection, especially with HR-HPV genotypes infect genital tract, which caused Condyloma acuminatum and cervical lesions, or cervical cancer. The detection of HPV genotypes was very important to prevent, diagnose early and therapy for cervical lesions or cervical cancer.  相似文献

Background The prevalence of Helicobacterpylori (H. pylon) infection varies by geographic locations. Studies indicate that the infection rate of H. pylori was previously high in China but that rates had been declining worldwide over recent decades. The aims of our study were: (1) to determine the current prevalence of H. pylori infection among children and adults residing in areas with high (Muping County, Shandong) and low (Yanqing County, Beijing) incidences of gastric cancer in China, and (2) to compare the prevalence for 2006 with the prevalence for the early 1990s. Methods Using Warthin-Starry silver staining of gastric mucosal biopsy specimens and H. pylori stool antigen tests (HpSA), we tested a total of 2065 asymptomatic children aged 8-15 years and adults aged 40-79 years in the above two regions from May to July 2006. We evaluated 520 children and 526 adults from Muping, and 516 children and 503 adults from Yanqing. Subjects were selected randomly and H. pylori status was determined by HpSA in children and either HpSA or histology of gastric biopsies in adults. Data obtained in the early 1990s in the same two areas of China were also collected and studied. Results For children, the prevalence of H. pylori infection was significantly higher in Muping (37.69%) than it was in Yanqing (25.58%, P〈0.001). In both regions, the prevalence of H. pyloriincreased with age but was not related to gender A significant difference was observed between 8-9-years old and 10-11-years old (P 〈0.05), but not between other adjoining age groups (P 〉0.05). From 1991 to 2006 H. pylori prevalence among 8-10-year-old children decreased in Muping (60.00% vs 32.07%, P 〈0.001), but not Yanqing (24.06% vs 19.10%, P 〉0.05). In the adult group, H. pylori prevalence was 50.95% in Muping, which was significantly higher than the 41.35% positive rate in Yanqing (P 〈0.01). But there were no statistically significant differences between different age groups of 40-49, 50-59, and 60-79 years, or between males and females. A significant decrease in H. pylori prevalence in both regions was observed when the results of 2006 were compared with the data obtained in 1990 in Muping (50.95% vs 73.78%, P 〈0.001) and in 1992 in Yanqing (41.35% vs 55.35%, P〈0.01). Conclusions After fifteen years, the prevalence of H. pylori infection among both children and adults remained significantly higher in areas with a high incidence of gastric cancer in China compared with that in areas with a low incidence of gastric cancer. H. pylori infection rates have decreased in the general Chinese population during recent years.  相似文献

SPECIFIC UP-REGULATION OF DNA POLYMERASE BY HUMAN PAPILLOMAVIRUS 16   总被引:1,自引:0,他引:1  
Obje, etive To analyze how the infection of human papillomavirus 16 ( HPV16 ) affects expression of DNA poly- merase β(DNA polB) with the aim of probing the mechanism of over-expression of DNA polB in human cancers. Methods Four fragments of human DNA polB promoter were amplified and constructed into luciferase reporter vec- tor pGL-Basic, generating pGL-BP, pGL-BMH, pGL-BMS, and pGL-BAT constructs respectively, and co-transfected with HPV16 or HPV6 into Hep2 cells. Luciferase activity was assayed 48 hours after transfectiorL Semi-quantitative RT- PCR was used to measure mRNA expression of endogenous DNA polB. Immunohistochemistry and in situ hybridization were used to analyze DNA polB expression and HPV16 or HPV6 infection in 38 cases of cervical lesions respectively. Results With co-transfection of HPV16 and DNA polB promoter-driving reporters into Hep2 cells, pGL-BP re- porter in full-length DNA polB promoter presented markedly elevated luciferase activities ( P 〈 0.05 ). However, the other three mutant reporters: pGL-BMH, pGL-BMS, and pGL-BAT, generated no reporting activities in the presence of HPV16 (P 〉0.05 ). On the contrary, all of polB promoter reporters were little stimulated in co-transfection of HPV6 (P 〉0.05 ). The transfection of HPV16 could enhance the endogenous polB mRNA expression compared with that of HPV6 (3.42 vs. 0.80, P 〈0.05). The DNA polB expression was found in 8 of 10 HPV16-positive cervical intraepi- thelial neoplasia grade Ⅲ( CIN Ⅲ) cases, while was only found in 3 of 11 HPV6-positive condyloma accuminatum cases, but was negative in all chronic cervicitis cases. The correlation of DNA polB expression with HPV16 infection in cervical lesions was significant ( P 〈0.05 ). Conclusions HPV16 is able to specifically stimulate the expression of DNA polB in human epithelial cells through interaction with the core upstream regulatory sequences of DNA polB promoter. Over-expression of DNA polB might be an explanation for the molecular mechani  相似文献
