Study on the Correlation between Human Papillomavirus and Mycoplasma genitalium Combined with TCT Detection

Objective: This study aims to explore the correlation between human papillomavirus (HPV) and Mycoplasma genitalium (CT) combined with TCT detection in cervical cancer screening. Method: A cross-sectional study design was adopted, and a total of 609 women who came to seek medical treatment were recruited as the study subjects. Combination testing was evaluated on cervical cancer screening by testing the women for HPV, CT with TCT detection and analyzing the relationship of cervical lesions with HPV and CT infection. Results: The study results showed that 21.57% of the subjects were infected with both HPV and CT, and 48.42% of the cases had abnormal TCT results at the same time. Further data analysis showed that HPV infection was significantly associated with abnormal TCT outcomes (p < 0.05), suggesting a possible synergistic effect of the two infections in cervical lesions. The combined sensitivity and specificity of HPV, CT and TCT detection were 21.57% and 48.42%, respectively, which were significantly higher than that of single detection. Conclusion: In summary, the results of this study support the importance of combined HPV, CT, and TCT testing in cervical cancer screening, and propose the hypothesis that combined testing may improve screening effectiveness. However, further large sample studies are needed to confirm this conclusion and explore the prospects of combined testing in clinical practice.

Evaluating the Association between Human Papillomavirus and Vulvar Cancer:A Comprehensive Analysis Using Bradford Hill Criteria

Background:The role of human papillomavirus(HPV)in the development of vulvar cancer(VC)has been widely studied,but findings have been inconsistent.Despite numerous meta-analyses exploring the potential link between HPV and VC,the association remains controversial due to inherent limitations in meta-analytic methods.Objectives:To address this controversy,the study aims to investigate the potential link between HPV and VC using the Bradford Hill criteria,which offer a more comprehensive framework for establishing causation.Methodology:The study began by extracting all relevant studies on the association between HPV and VC from the PubMed database.The potential links were then assessed by examining the data using the major postulates of the Bradford Hill criteria.To ensure the reliability of the findings,the methodologies of the identified studies were critically evaluated to account for possible false-negative and false-positive results.Results:The assessment of previous studies against the Bradford Hill criteria revealed that the major postulates were not fulfilled.Conclusion:Based on the findings,it can concluded that there is no causal association between HPV and VC.

Distribution of High-Risk Human Papillomavirus Genotypes among Women with Colposcopic Diagnosis of Cervical Intraepithelial Neoplasia in Bangladesh

Background: The incidence of cervical cancer is high in Bangladesh and there is a high prevalence of preinvasive lower genital tract disease among women of reproductive age. Persistent high-risk Human Papilloma Virus (HPV) infection is the main underlying cause of cervical cancer and its precursor, cervical intraepithelial neoplasia (CIN). Objective: The aim of the study was to identify the subtypes of high-risk HPV infection among women with the colposcopic diagnosis of cervical intraepithelial neoplasia in Bangladesh. Methods: This cross-sectional observational study was conducted in the colposcopy clinic of Dhaka Medical College Hospital over a six-month period. A total of 100 participants were enrolled. Married women, between 30 - 60 years of age with colposcopically diagnosed cervical intra epithelial neoplasia were enrolled. Women with chronic illness, pregnancy, and women unable to consent were excluded from this study. After counselling, colposcopically directed punch biopsies were taken from each CIN case concurrently with high-risk HPV testing by polymerase chain reaction (PCR). Results: The mean age of the patients was 38.69 (SD ±7.76) years. CIN 1 was diagnosed in 57% of participants, while 24% had CIN II and 19% had CIN III lesions. High-risk HPV was present in 52 patients. HPV 16 was the most common identified in 28 (53.84%) and HPV 18 was the second most common with 20 (38.46%) either singly or in combination with other high-risk subtypes. The other HPV strains, HPV 31, 33, 35, 52, 56 and 58, were also detected either as mono or co-infections. Out of the 52 HPV positive cases, 29 (55.8%) had mono infection and 23 (44.2%) had co-infection with several subtypes. The highest incidence (50%) of oncogenic HPV infections was present among women aged 35 - 45 years. Risk factors associated with HPV positive cases were high parity (P 0.05), early age at marriage (P = 0.754) and early age of first child. Conclusion: This study identified a high prevalence of HPV 16 and 18 genotypes. HPV vaccination with the current 9-valent HPV vaccine, which contains HPV types 6, 11, 16, 18, 31, 33, 45, 52, and 58. Will be an effective public health measure to eradicate cervical cancer in Bangladesh.

Human Papillomavirus as an Independent Predictor in Oral Squamous Cell Cancer

Aim There is an increasing evidence for the role of high risk human papillomavirus （HPV） in the pathogenesis of oral squamous cell carcinoma （OSCC）. The purpose of this study is to evaluate the relevance of HPV infection to the survival and prognosis of OSCC. Methodology Fifty-two patients with OSCC were followed from 4 to 88 months with a median of 50.7 months. HPV DNA was identified in formalin-fixed, paraffin-embedded tumor specimens by nested PCR with MY09/MY11 and GP5^＋/GP6^＋ primer pairs and the HPV genotype was determined by direct DNA sequencing. Association between the HPV status and risk factors for cancer as well as tumor-host characteristics were analyzed.Survival curves were calculated by the Kaplan-Meier method and analyzed using the log-rank test. Results HPV was found in 40.4% of the tumors with HPV16 accounting for 63.5%, HPV18 for 30.8%, HPV6 for 3.9% and HPVll for 1.8%. No infection with more than one HPV genotype was detected. HPV infection was significantly associated with poor histological grade, TNM stage Ⅰ -Ⅱ, alcohol usage and no smoking status. Multivariate analysis showed that HPV had an independent prognostic effect on the overall survival after adjusting other confounding factors such as histological grade, TNM stage and tobacco usage. The presence of HPV was significantly correlated with a better survival in patients with OSCC. Conclusion HPV infection can act as an independent predictor for the survival and prognosis of OSCC.

HPV拓展分型联合液基细胞学筛查对宫颈高级别上皮内病变的诊断价值研究

Apoptosis of HeLa cells inhibited by human papillomavirus type 16 E6 protein interacting with hDaxx

Objective: To study the interaction of human papillomavirus type 16 (HPV16 E6) protein and human death domain associated protein (hDaxx) and its effect on apoptosis of HeLa cells to provide the experimental basis for exploring the oncogenic mechanism of HPV16 E6 protein. Methods: Recombinant vector of pGADT7/E6 or pGBKT7/hDaxx was con- structed. The interaction of E6 protein and hDaxx was detected by yeast two-hybrid system. Their expression in yeast was detected by Western blotting. The eukaryotic plasmids of E6 and hDaxx were co-transfected into HeLa cells. Apoptosis was induced by 5-FU. The apoptotic rate was measured by flow cytometry (FCM). Results: E6 protein had intracellular interaction with hDaxx. The apoptotic rate was rising with the increase in the transfection quantity of pcDNA3.1 (-) / hDaxx in pcDNA3.1 (-) /E6 and pcDNA3.1 (-) / hDaxx co-transfected cells. The difference was significant ( P < 0. 01). Conclusion: There is intracellular interaction between HPV16 E6 protein and hDaxx. The over-expression of hDaxx can increase the sensitivity of E6 protein positive HeLa cells to 5-FU. The effect was in a dose dependent manner. HPV16 E6 protein inhibited the apoptosis of HeLa cells by interacting with hDaxx.

Detection and Identification of Human Papillomavirus in Cervical Adenocarcinoma

Objective： To evaluate the rate and types of human papillomavirus （HPV） infection in cervical adenocarcinoma. Methods： We detected and identified HPV in 67 lesions using PCR based reverse line blot hybridization and DNA sequencing. Among the 67 patients, 53 were diagnosed as cervical adenocarcinoma and 14 as cervical adenosquamous carcinoma. First a fragment of 150 bp was amplified from the L1 region of HPV with GP5/GP6 primers. If the result was negative, a short fragment of 65 bp was amplified from the L1 region with SPFI/SPF2 primers. Results： 6 cases were eliminated from the study because of unsatisfied DNA extraction. The total positive rate of HPV DNA detected by PCR in cervical adenocarcinoma and adenosquamous carcinoma was 91.8% （56/61）. Using general primer GP5/GP6, the positive rate was 50.8% （31/61）. Using SPF primers for the 30 negative cases, 25 additional HPV positive cases were founded. All the positive samples had at least one of the high risk types. HPV16 was the most preferential type followed by HPV18, 31, 39 and 45. The infection of HPV 16 and 18 accounted for about half of HPV-positive adenocarcinoma. Multiple HPV infections were found in 21.4% （12/56） of the cases. Conclusion： The high risk type of HPV is associated with cervical adenocarcinoma. Single infection is more frequently presented than multiple infections, no single type of HPV plays a predominated role even HPV16 and 18 are the major types.

Expression of Human Papillomavirus in Mammary Carcinoma and its Possible Mechanism in Carcinogenesis

To explore the role of Human papillomavirus (HPV) in mammary carcinogenesis, the expression of the HPV-16, iNOS , P53 and hTERT proteins in breast carcinomas and their relationships were investigated. 52 samples of breast cancer and 16 samples of benign breast tumors were assayed using the immunohistochemical SP method for detection of protein expression levels. The expression of HPV-16, iNOS, P53 and hTERT proteins in a mammary carcinoma was 44.2%, 57.7%, 63.5% and 59.6% respectively, which was significantly greater than the corresponding levels in the benign group. The expression of iNOS, P53 and hTERT was correlated with the presence of an HPV-16 infection in a mammary carcinom(aP<0.05). The connection between these events might also involve the iNOS, mutated type P53 and the hTERT protein.

THE DETECTION OF P53 GENE IN HUMAN CERVICAL CARCINOMA WITH AND WITHOUT HUMAN PAPILLOMAVIRUS INFECTION

The special primers Of p53 exon 7 as wed as HPV16 E6 and E7 ORFs (Opening Rending Frame) were used with PCR, PCR-SSCP technique, and 35 specimens of cervical carcinoma were examined. The results were as follows: ① HPV16 E6, E7 DNA was found in 25/35 specimens (71. 4%),which proved again HPV16 Infection an important event in cervical carcinogenesis. However only 11/35 (31.42% ) bad E6 and E7 ORFs simultaneously, 3/35 (8. 57%) and 11/35 (31. 42% ) had only E6 or E7 respectively. ② No mutation and LOH (Loss of Heterozygote) of p53 exon 7 were found in allof 35 specimens. Additionally in the present study, we developed a non-isotopic PCR-SSCP method.

The Relationship between Human Papillomavirus and Oesophageal Squamous Cell Carcinoma in China—A Review of the Evidence

Background: China has one of the highest incidence rates of oesophageal cancer in the world. The role of human papillomavirus (HPV) has been extensively researched in oesophageal squamous cell carcinoma (OSCC) with indeterminate results. The majority of these studies have been conducted in the Chinese population. Evidence for a definitive HPV-OSCC association could potentially support prophylactic vaccination in target populations, highlighting the need for ongoing investigation. The aim of this review is to summarise the findings of HPV DNA in OSCC tissue in Chinese subjects, with a view to informing further research in this area. Methods: A systematic literature search of the Chinese National Knowledge Infrastructure (CNKI) database, Medline, Embase and PubMed was conducted for all studies in English and Chinese language, examining OSCC tissue for HPV DNA in China. Reference lists of retrieved articles were reviewed and hand searches of relevant, key journals were conducted, to source articles which were not electronically indexed. Sixty-four studies met our selection criteria. Data from case-control and cross-sectional studies were analysed separately for any HPV-OSCC association, using the Epi InfoTM 3.5.3 software program. Results: From all studies conducted in the Chinese population, 2166/5953 (36%) of all OSCC tissue and 478/1684 (28%) of healthy control tissue, tested positive for HPV. We found that 11/16 case-control and cross-sectional studies had a statistically significant crude odds ratio, which supported a potential HPV-OSCC association. The largest study, carried out in the high incidence County of Anyang in Henan Province, reported 207/265 (78%) OSCC tissues testing positive for HPV DNA against 203/357 (57%) controls and had an unadjusted odds ratio of 2.71 (p-value Conclusion: A rigorous meta-analysis would improve interpretation of the data and a well-designed large-scale case-control study is warranted. If a link is found between HPV and OSCC, prophylactic HPV vaccines could be of significant benefit in China.
