①目的探讨人乳头状瘤病毒16,18型(HPV-16,HPV-18)感染与慢性宫颈炎、宫颈癌的关系。②方法聚合酶链反应(PCR)技术检测22例正常宫颈、55例慢性宫颈炎、30例宫颈癌的子宫颈组织。③结果正常宫颈组织中HPV-16,18的检出率均为0.00%,慢性宫颈炎分别为18.18%和7.27%,宫颈癌分别为56.67%和3.33%.统计学处理表明,宫颈癌组织中HPV-16的检出率明显高于宫颈炎组织(χ2=13.624,P<0.01),而且Ⅲ度宫颈糜烂组织中HPV-16的检出率也较Ⅰ,Ⅱ度的检出率高,两者比较差异有显著意义(χ2=10.550,P<0.01),但不同宫颈疾患组织中HPV-18的检出率无统计学意义。④结论子宫颈癌的发生与HPV感染密切相关,以HPV-16尤为明显,PCR技术是检测组织中HPV-DNA的敏感、特异的方法  相似文献

应用双温聚合酶链反应(PCR)检测喉乳头瘤石蜡包埋组织中的人乳头瘤病毒(HPV)DNA。结果与常规PCR(三温循环)相同:30例喉乳头瘤中HPV总检出率为46.7%(14/30),HPV-6/11/16的检出率分别为40%(12/30)、16.7%(5/30)和6.7%(2/30),HPV-6的检出率极显著高于HPV-11/6(x2=10.6,P<0.01)。初步结果表明,本地区喉乳头瘤主要与HPV-6的感染密切相关。该法具有缩短检测时间、节省一个恒温水浴箱等优点。  相似文献

对用肉眼形态、组织学特征和人乳头瘤病毒核壳抗原(HPV-Ag)来检测诊断为尖锐湿疣和假性湿疣的两组病例,用广谱人乳头瘤病毒DNA探针,作核酸原位杂交检测,结果:尖锐湿疣组HPV-DNA检出率为30/33(90.9%),而假性湿疣组检出率仅为1/38(2.6%)(P<0.0001),提示假性湿疣并非为HPV感染引起,或HPV感染的可能性很小。作者还对应用广谱人乳头瘤病毒DNA原位杂交作为对疑为HPV感染病变作病理学初筛检测的意义作了讨论。  相似文献

应用DNA-DNA斑点杂交技术,对64例宫颈标本(包括正常宫颈26例,重度宫颈糜烂17例,宫颈癌21例)分别检测HPV-16DNA及HCMVDNA。结果发现正常宫颈、宫颈糜烂及宫颈癌组织中HPV16DNA的检出率分别为23.08%、64.71%、71.43%。而HCMVDNA的检出率则依次为3.85%、23.54%、及42.86%,两者检出率呈直线相关(r=0.923)。因此,推测HCMV很可能与HPV16协同作用导致宫颈癌的发生。  相似文献

人乳头瘤病毒与食管鳞癌及不典型增生相关性的研究   总被引:1,自引:0,他引:1  
目的研究重庆地区食管癌组织中人类乳头状瘤病毒(HPV)感染与食管鳞癌发生的关系。方法收集112例食管鳞状细胞癌标本和38例非典型增生食管上皮及74例正常食管黏膜组织。运用荧光定量PCR方法分别检测各组织标本中HPV-16、18型的感染状况。结果食管鳞癌组织、非典型增生上皮及正常黏膜中HPV-16DNA的检出率分别为38.4%(43/112)、15.9%(6/38)和5.4%(4/74)。鳞癌组织中HPV-16的检出率明显高于非典型增生上皮和正常食管黏膜(P〈0.05),非典型增生上皮中HPV-16的检出率虽远高于正常食管黏膜,但统计学差异未见显著性;食管鳞癌中HPV-16的阳性检出率与其分化程度未见明显相关。所有组织标本均未检出HPV-18DNA。结论HPV-16的感染可能是重庆地区食管鳞癌发生的之一高危因素;积极开展防治高危型HPV感染对降低该地区食管鳞癌的发病率具有重要的意义。  相似文献

BACKGROUND: Two molecular methods for HPV genotyping in formalin-fixed, paraffin-embedded tissue were evaluated: in house polymerase chain reaction assay (PCR) with consensus and type-specific primers and a novel procedure of in situ hybridization-a catalyzed signal amplification system (CSA-ISH, Genpoint, DAKO, Glostrup, Denmark). The number of HPV positive cases and detected viral types were compared in cervical biopsies and cone specimens according to histopathological diagnosis. Primer efficiency in detecting various types of HPV by PCR method was evaluated. METHODS: DNA samples (101) were used as a template to amplify with three pairs of consensus (MY09/11, GP5+/6 +, CPI/IIG) and four type-specific HPV primers (HPV-6/11, 18, 16 and 33). The according histological tissue sections were analyzed with CSA-ISH method, using commercial HPV biotinylated probes HPV-6/11, 16/18 and 31/33/51. RESULTS: The degree of concordance for PCR and CSA-ISH was 64.4%. In 63 of 101 samples (62.4%), HPV was detected by PCR, while only 35 (34.7%) were positive using CSA-ISH. CSA-ISH found lower percentages for all HPV types, except HPV-6/11. A lower percentage of positive results in all high-grade lesions was detected by CSA-ISH. Multiple infections were detected by PCR in only one sample and in three samples by CSA-ISH. Detection with My09/11 primers followed by Gp5+/6+ primers, in nested reaction, gave the highest number of positive results: 58 of 63 (92%). None of the samples diagnosed as condylomata planum or CIN I was positive for HPV-6/11 (low risk type), which was detected exclusively in condylomata acuminatum group. CONCLUSIONS: A significantly higher number of positive samples was detected with PCR than with CSA-ISH method. CSA-ISH method should be improved, especially in detecting HPV in high-grade lesions. CSA-ISH may be more accurate in detection of multiple infections. GP5+/6+ in nested reaction after MY09/11 detected the highest number of positive results. Samples diagnosed as benign lesions positive on HPV-X must be monitored as possible candidates for progression. CIN I lesions, which were HPV negative, probably will not progress. This finding may be important in planning therapy and avoiding unnecessary treatment.  相似文献

Biopsy samples from 27 patients referred to a colposcopy clinic in Glasgow for cervical abnormalities were assessed for the relations among colposcopic appearances, cytological and histological diagnosis, expression of papillomavirus antigen, and the presence of human papillomavirus (HPV) types 6, 11, 16, and 18 deoxyribonucleic acid (DNA) sequences. Specimens were from colposcopically abnormal areas of the transformation zone and from colposcopically apparently normal areas of the zone in the same patients (paired matched internal control tissue). All 27 women referred for abnormal smears had colposcopic abnormalities. HPV-16 or 18 DNA sequences were detected in 20 of the 27 colposcopically abnormal biopsy samples and 13 of the 27 paired normal samples. Twelve samples of colposcopically normal tissue contained histological evidence of viral infection but only four of these contained HPV DNA sequences. The other nine samples of colposcopically normal tissue which contained HPV DNA sequences were, however, histologically apparently normal. HPV-6 and 11 were not detected. Integration of the HPV-16 genome into the host chromosome was indicated in both cervical intraepithelial neoplasia and control tissues. In two thirds of the HPV DNA positive samples the histological grade was classed as normal, viral atypia, or cervical intraepithelial neoplasia grade 1. Papillomavirus antigen was detected in only six of the abnormal and three of the normal biopsy samples, and HPV DNA was detected in all of these. The detection of HPV DNA correlates well with a combination of histological and cytological evidence of viral infection (20 of 22 cases in this series). A poor correlation between the site on the cervix of histologically confirmed colposcopic abnormality and the presence of HPV DNA sequences implies that a cofactor other than HPV is required for preneoplastic disease to develop. A separate study in two further sets of biopsy samples examined the state of HPV DNA alone. The sets were (a) 43 samples from cervical intraepithelial neoplasia and nine external controls and (b) 155 samples from cervical intraepithelial neoplasia, cervical cancer, vulval intraepithelial neoplasia, and vulval cancer and external controls. HPV-11 was found in only two (4.7%) of the 43 specimens from cervical intraepithelial neoplasia, whereas HPV-16 was found in 90 (58%) of the other 155 specimens. These results also suggest that HPV subtype is subject to geographical location rather than being an indicator of severity of the lesion or of prognosis.  相似文献

Punch biopsy specimens of the cervix were examined both histologically and for the presence of human papillomavirus (HPV) DNA sequences. The presence of HPV DNA sequences was sought with the Southern blot technique using radioactively labelled HPV-6, 11, 16, and 18 DNA probes, both together and separately. Twenty six biopsy specimens were examined. Histological examination showed cervical intraepithelial neoplasia grade 2 or 3 in 16 specimens, viral changes (koilocytosis) in four, and inflammation or a normal appearance in three. Eleven specimens were negative for HPV DNA sequences, 10 contained HPV-16 DNA, four contained HPV-18 DNA, and one contained both HPV-18 and HPV-11 DNA. Episomal HPV-16 DNA was detected in one case of cervical intraepithelial neoplasia grade 3 and in five cases of cervical intraepithelial neoplasia grade 2/3 with koilocytosis; and episomal HPV-18 DNA was found in two specimens classed as cervical intraepithelial neoplasia grade 2/3, one of which also contained HPV-11 DNA, and in one specimen that showed viral changes alone. Integrated HPV DNA was found in six specimens (four with HPV-16 DNA and two with HPV-18 DNA), including two cases of chronically inflamed cervix with no histological evidence of viral infection or cervical intraepithelial neoplasia. Detection of viral DNA in early lesions may identify patients at risk of malignant progression. This is the first report of HPV-18 DNA in cervical intraepithelial neoplasia in Scotland.  相似文献
