Objective:To evaluate the efficacy of high-risk HPV (HR-HPV) genotyping with vaginal self-sampling in primary screening and combining cytology or viral load for HR-HPV positive as secondary screening strategies.Methods:The data referring to HR-HPV genotyping of self-collected sample with mass array matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF-MS), HR-HPV viral load of physician-collected sample with hybrid capture Ⅱ (HC-Ⅱ), liquid-based cytology and histology of 8 556 women were from Shenzhen cervical cancer screening trial Ⅱ (SHENCCAST-Ⅱ) conducted between April 2009 and April 2010. The data were reanalyzed to determine the sensitivity and specificity to cervical intraepithelial neoplasia (CIN) of grade 2 or worse (CIN Ⅱ +), CIN of grade 3 or worse (CIN Ⅲ +) when HR-HPV genotyping combining with colposcopy as primary screening strategy based on varied HR-HPV subtype (strategy 1, including 5 sub-strategies: 1a: HPV 16/18 positive; 1b: HPV 16/18/58 positive; 1c: HPV 16/18/58/31/33 positive; 1d: HPV 16/18/58/31/33/52 positive; 1e: any HR-HPV positive). The data were also compared to determine the efficacy of cytology (strategy 2, including 5 sub-strategies: 2a, 2b, 2c, 2d, 2e) or HR-HPV viral load (strategy 3, including 4 sub-strategies: 3a, 3b, 3c, 3d) of physician-collected sample as a triage with HR-HPV genotyping for self-sampling HR-HPV positives. Results:(1) The HR-HPV positive rate was 13.77% (1 178/8 556) in the self-collected samples of 8 556 pregnant women. Of them,the prevalences of HPV 16/18, HPV 16/18/58, HPV 16/18/58/31/33 and HPV 16/18/58/31/33/52 were 3.16% (270/8 556), 5.14% (440/8 556), 6.66% (570/8 556) and 9.81% (839/8 556), respectively. The HR-HPV viral load ≥10 relative light units/control (RLU/CO) was 8.87%(759/ 8 556), while cytological results ≥atypical squamous cell of undetermined signification (ASCUS) were 12.05% (1 031/8 556). (2) The strategy 1e had the highest sensitivities for CIN Ⅱ +, CIN Ⅲ + which were 92.70% and 94.33%,respectively,among 14 sub-strategies,while the lowest specificity and positive predictive value (PPV). Meanwhile,the required colposcopy referral rates were much higher than other 13 sub-strategies (13.77%). The other 4 sub-strategies of strategy 1 (1a, 1b, 1c, 1d), strategy 1a had the highest specificities for CIN Ⅱ + and CIN Ⅲ + (97.92%, 97.69%, respectively), while 1d had the highest sensitivities for CIN Ⅱ + and CIN Ⅲ + (88.41%, 92.20%, respectively). (3) Both strategies of referring self-sampling HPV 16/18 positives for immediate colposcopy followed by triage physician-collected sample cytology (≥ASCUS) or viral load (≥10 RLU/CO) for non-HPV 16/18 positives had significantly higher sensitivity and specificity for CIN Ⅱ, CIN Ⅲ +, as well as lower referral rates (strategy 2a and 3a). Additionally, based on these two secondary screening strategies, cumulatively using the other four HR-HPV (HPV 58, 31, 33 and 52) positives as triage for immediate colposcopy showed an enhanced sensitivity. Conclusions:Primary HR-HPV cervical cancer screening strategy based on self-sampling with triage of cytology (≥ASCUS) or viral load (≥10 RUL/CO) provides a good balance among sensitivity, specificity for CIN Ⅱ + and CIN Ⅲ + and the number of tests required, referral rates. The efficacy of HR-HPV genotyping combining cytology or viral load secondary screening strategies will have a spiral escalation when HPV 58, 31, 33, 52 are included.

Objective:Evaluation of the clinical value of the BioPerfectus multiplex real time (BMRT)-HPV for cervical cancer screening.Methods:Physician-collected specimens of 1 495 women who were positive of Cobas 4800 HPV (Cobas-HPV), HPV genotyping based on SEQ uencing (SEQ-HPV), and (or) cytology ≥low grade squamous intraepithelial lesion (LSIL) in the primary screening of Chinese Multiple-center Screening Trial (CHIMUST), and 2 990 women selected from those who were negative of primary screening in the same project through nested control randomization with age-matching were tested for BMRT-HPV, which reported type-specific viral loads/10 000 cells in each specimen. With comparing to Cobas-HPV results and taking cervical histopathological diagnosis as the endpoint, the concordance of high-risk (HR)-HPV subtypes among the three assays was explored ,and the sensitivity and specificity of BMRT-HPV for cervical cancer screening were evaluated.Results:(1) The overall agreenment of HR-HPV subtypes between BMRT-HPV and Cobas-HPV, or SEQ-HPV test sample was 94.8%, 94.4%, with Kappa values 0.827, 0.814. (2) The sensitivity and specificity for cervical intraepithelial neoplasia (CIN) Ⅱ + of BMRT-HPV, Cobas-HPV and SEQ-HPV were 92.62%, 94.26%, 93.44% and 84.67%, 83.25%, 82.76%, respectively. There were no significant difference in sensitivity among the three HPV assays (all P>0.05), but the specificity of BMRT-HPV for CIN Ⅱ + was higher than those of Cobas-HPV and SEQ-HPV ( P<0.01). The sensitivity for CIN Ⅲ + of three HPV assays were all 100.00%, and the specificity for CIN Ⅲ + of BMRT-HPV was higher than those of Cobas-HPV and SEQ-HPV (83.40% vs 81.95%, 83.40% vs 81.50%; P<0.01). The number of pathological examinations of colposcopy for cervical biopsy detected in 1 case of CIN Ⅱ + or CIN Ⅲ + in BMRT-HPV was less than those in Cobas-HPV and SEQ-HPV ( P<0.01). When using HPV 16/18 + cytology ≥atypical squamous cell of undetermined signification (ASCUS) to triage HPV positive women among three assays, there was no different in the sensitivities of detecting CIN Ⅱ + and CIN Ⅲ + ( P>0.05). The specificity BMRT-HPV was slightly higher than those in Cobas-HPV or SEQ-HPV (all P<0.05), and the colposcopy referral rate was lower than those in Cobas-HPV and SEQ-HPV (all P<0.05). Conclusions:BMRT-HPV is as sensitive as Cobas-HPV or SEQ-HPV for primary cervical cancer screening, and has higher specificity. Therefore it could be used as a primary screening method for cervical cancer, which is worthy of clinical application.

Objective:To evaluate the value of p16 INK4a detected by p16 INK4a immunostaining as a new generation of cervical cytology for primary screening and secondary screening in population-based cervical cancer screening, and in improving cytological diagnosis. Methods:Between 2016 and 2018, 5 747 non-pregnant women aged 25-65 years with sexual history were recruited and underwent cervical cancer screening via high-risk (HR)-HPV/liquid-based cytological test (LCT) test in Shenzhen and surrounding areas. All slides were immuno-stained using p16 INK4a technology, among them, 902 cases were offered p16 INK4a detection during primary screening, and the remaining 4 845 cases were called-back by the virtue of abnormal HR-HPV and LCT results for p16 INK4a staining. Participants with complete LCT examination, HR-HPV test, p16 INK4a staining and histopathological examination results were included in this study. The performance of p16 INK4a in primary and secondary screening, and in assisting cytology to detect high grade squamous intraepithelial lesion [HSIL, including cervical intraepithelial neoplasia (CIN) Ⅱ or Ⅲ] or worse [HSIL (CIN Ⅱ) + or HSIL (CIN Ⅲ) +] were analyzed. Results:(1) One-thousand and ninety-seven cases with complete data of p16 INK4a and histology were included. Pathological diagnosis: 995 cases of normal cervix, 37 cases of low grade squamous intraepithelial lesion (LSIL), 64 cases of HSIL and one case of cervical cancer were found. Among them, 65 cases of HSIL (CIN Ⅱ) + and 34 cases of HSIL (CIN Ⅲ) + were detected. The positive rate of p16 INK4a in HSIL (CIN Ⅱ) + was higher than that in CINⅠ or normal pathology (89.2% vs 10.2%; P<0.01). (2) p16 INK4a as primary screening for HSIL (CIN Ⅱ) + or HSIL (CIN Ⅲ) + was equally sensitive to primary HR-HPV screening (89.2% vs 95.4%, 94.1% vs 94.1%; P>0.05), but more specific than HR-HPV screening (89.8% vs 82.5%, 87.7% vs 80.2%; P<0.05). p16 INK4a was equally sensitive and similarly specific to cytology (≥LSIL; P>0.05). (3) The specificity of LCT adjunctive p16 INK4a for detecting HSIL (CIN Ⅱ) + or HSIL (CIN Ⅲ) + were higher than that of LCT alone or adjunctive HR-HPV ( P<0.01), while the sensitivity were similar ( P>0.05). (4) p16 INK4a staining as secondary screening: p16 INK4a was significantly more specific (94.1% vs 89.7%, 91.9% vs 87.4%; P<0.01) and comparably sensitive (84.6% vs 90.8%, 88.2% vs 91.2%; P>0.05) to cytology for triaging primary HR-HPV screening. HPV 16/18 to colposcopy and triage other HR-HPV with p16 INK4a was equally sensitive (88.2% vs 94.1%; P=0.500) and more specific (88.3% vs 83.0%; P<0.01) than HPV 16/18 to colposcopy and triage other HR-HPV with LCT≥ atypical squamous cells of undetermined significance (ASCUS), and the referral rate decreased (14.0% vs 19.4%; P=0.005). Conclusions:For primary screening, p16 INK4a is equally specific to cytology and equally sensitive to HR-HPV screening. p16 INK4a alone could be an efficient triage after primary HR-HPV screening. In addition, p16 INK4a immunostaining could be used as an ancillary tool to cervical cytological diagnosis, and improves its accuracy in cervical cancer screening.

Objective To evaluate the feasibility of the BioPerfectus multiplex real time (BMRT) HPV assay for self-sample cervical cancer screening. Methods Eight hundreds and thirty-nine self-collected and physician-obtained DNA samples from the Shenzhen cervical cancer screening trialⅣ(SHENCCAST-Ⅳ) study collected samples for cervical cancer screening during June 2013 to September 2014 were detected by BMRT HPV assay to evaluate the screening efficacy. Results A total of the 839 women who were screened, 804 with complete BMRT HPV data was included in the study, and average age was (46±7) years. Of the 804 women, the positive rates of 14 high-risk HPV genotypes (including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 subtype) of self-sample and physician-obtained samples were 12.2% (98/804) and 12.8% (103/804), respectively (χ2=0.14, P=0.71). Self-collected samples with HPV-positive had significantly more cells (median 19 901.0) than physician-obtained samples (median 1 778.4), and there was statistically significant difference (Z=-7.61, P<0.01). The degree of agreement between self-sample and physician-obtained samples of HPV 16, HPV 18 and other 12 high risk HPV genotype was 99.8%, 100.0% and 96.1%, respectively. And the consistent Kappa value was 0.95,1.00 and 0.81, respectively. Of 804 samples, there were 6 cervical intraepithelial neoplasia (CIN)Ⅱ+cases. There were no missed CINⅡ+cases by BMRT HPV assay. Conclusion BMRT HPV assay is feasible for self-sample cervical cancer screening.

Objective To explore the relationship between cervical lesions and high risk HPV (HR-HPV) viral load reflected by the cycle threshold (Ct) values of Cobas 4800 HPV (Cobas 4800) system. Methods From August 2016 to September 2017, 7 000 women from Shenzhen, were recruited for cervical cancer screening with Cobas 4800 system and cytology co-test. Colposcope biopsies were performed on women who were positive of HPV 16, 18, and positive of HPV types other than 16, 18 with cytology [≥atypical squamous cell of undetermined signification (ASCUS)], or HPV negative but abnormal of cytology [≥low grade squamous intraepithelial lesion (LSIL)]. The Ct values of HPV 16, 18 and all combined other types coming from Cobas 4800 system were used as an indicator of viral load to analyze the relationship between type-specific HPV load and the cervical lesions. Results (1) Among the 7 000 screening women, 370 cases were positive for cervical cancer screening, 325 of them underwent colposcope biopsies, and coloposcopy referred rate was 87.8% (325/370). Among 325 women undergoing cervical biopsy, pathological diagnosis was 119 cases of normal cervical cervix, 151 cases of LSIL, and 55 cases of high-grade squamous intraepithelial lesion (HSIL) and above (HSIL+; including 53 cases of HSIL, 1 case of cervical adenocarcinoma, and 1 case of cervical squamous cell carcinoma). (2) The Ct value of HPV 16 was inversely correlated with the upgrading of the lesions (r=-0.617, P=0.000), and significant different among normal cervix,LSIL and HSIL+(35.4±4.5 vs 31.0±6.0 vs 26.5±4.0; F=25.537, P=0.000). There was no correlation between Ct value of HPV 18 and cervical lesions (r=-0.021, P=0.902). The Ct value of other 12 HPV types was statistically difference among normal normal cervix , HSIL+and cervicitis (33.0±5.3 vs 29.9±7.2 vs 29.8±5.8; F=5.087, P=0.007). Among them, LSIL and HSIL+ were significantly lower than normal cervix (P<0.05), but there was no significant difference between LSIL and HSIL+(P>0.05). Conclusion The Ct value of HPV 16 detecting in Cobas 4800 system as an indicator of virus load obviously correlates with different grades of cervical lesions, therefore could be a reference of cervical lesion existence and an indicator of lesion prognosis.

Objective To explore the human papilomavirus(HPV)genotypes and epithelial thickness of invisible cervical intraepithelial neoplasia Ⅲ(CIN Ⅲ)under colposcopy. Methods One hundred and sixty-nine biopsies from 93 patients with a final diagnosis of CIN Ⅲwere extracted from the Shenzhen cervical cancer screening trialⅡ(SHENCCASTⅡ).The SHENCCASTⅡwas conducted from 2009 to 2010.All the cervical blocks from these patients were re-cut and placed on 6 slides,i.e.sandwich model, with the top and bottom sections being stained with HE, the top second be processed for other studies, 3 sections for HPV genotypes by matrix-assisted laser desorption ionization-time of flight-mass spectrometry(MALDI-TOF-MS)assay.The thickness of squamous epithelium of CINⅢwas measured by a microscope(×10)after re-cut. Colposcope directed CIN Ⅲ biopsies positively was defined as visible CIN Ⅲ, while random CIN Ⅲ biopsies positively was defined as invisible CIN Ⅲ. Results HPV16 positivity was 37.2%(16/43)and 55.6%(70/126)between invisible and visible CIN Ⅲ biopsies, respectively(χ2=4.318,P=0.038).Forty-nine cases of the 93 CINⅢpatients were HPV16 positive,while 44 of them non-HPV16 positive. The proportion of patients with ≥45 years of age for other non-HPV16 positive 40.9%(18/44)was significantly higher than that HPV16 positive 20.4%(10/49; χ2=4.630, P=0.031).Patients with HPV16 positive were more likely to have lesions ≥1 quadrant(χ2=7.786,P=0.005) than other non-HPV16 positive. Compared the average epithelium thickness of invisible CIN Ⅲ tissue (140±12)μm,the average epithelium thickness of visible CIN Ⅲtissue(161±9)μm was thicker.There was statistical difference between two groups(t=4.383,P=0.038).The mean average epithelial thickness of CIN Ⅲwith HPV16 positive(172±11)μm was thicker than that the mean average epithelial thickness of CIN Ⅲ with non-HPV16 positive(130±10)μm(t=4.784,P=0.031). Conclusions Invisible lesions is difficult to identify under colposcopy and is related to non-HPV16 positive, small lesion size and thinner squamous epithelium. For non-HPV16 positive or older women should be performed colposcope directed biopsies and randomly multi-sites biopsies by colopscopy,which may be helpful to improve the detection of CINⅢand to reduce miss diagnosis.

Objective To investigate the significance of genomic amplification of the telomerase RNA component (TERC) gene to serve as a genetic biomarker in the screening of cervicallesions.Methods A total of 715 cases were recruited,with liquid-based cytology diagnosis as normal (n=347),atypical squamous cells of undetermined significance (ASCUS,n=180),atypical squamous cells cannot exclude a high-grade lesion (ASC-H,n=13),low-grade squamous intraepithelial lesions (LSIL,n=115),high-grade squamous intraepithelial lesions(HSIL,n=59)and atypical glandular cells(AGC,n=1).The remaining cervical cells in the cytological preserving fluid were analyzed using a two-color fluorescence in situ hybridization (FISH) probe targeted to chromosome 3q26 containing TERC gene.The TERC gene findings were compared to the cytological and histological detected results,as well as high-risk human papillomavirus (HPV) detected results.Results Genomic amplification of TERC gene was found in 5.8% of normal specimens,22.2% of ASCUS.30.8% of ASC-H,27.8% of LSIL,86.4% of HSIL and 1/1 of AGC.The positive rate was significantly lower in normal,ASCUS,ASC-H and ISIL.compared with HSIL(all P<0.01).Significantly more cells with genomic amplification of TERC gene were found in cervical intraepithelial lesion(CIN) Ⅱ-Ⅲ than CIN Ⅰ (77.8% vs.9.3%),as well as invasive cervical cancer (96.7% vs.9.3%).both P < 0.01.The rate of TERC gene amplification was higher in HPV positive patients (33.5%) than in HPV negative patients(5.2%,P<0.01).The sensitivity of TERC gene amplification was significantly higher than that of cytological screening (81.88% vs.36.96%,P<0.01) in the differentiation of CIN Ⅱ or higher and CIN Ⅰ or lower diseases,its specificity Was hisher than high-risk HPV test (93.32% vs.33.93%,P<0.01) and positive prediction value (81.29%) was similar with cytological method (86.44%,P>0.05);but its negative prediction value (93.56%) was lower than HPV test (97.06%,P<0.05).Conclusions The positive rates of TERC gene amplification increased as cervical diseases worsened.TERC gene amplification is related to HPV infection.The gain of chromosome 3q26 in cytological specimens is an effective molecular genetic biomarker in screening of CIN Ⅱ or higher and invasive cervical cancer.

Background and purpose:HPV infection is known as the primary cause of cervical cancer worldwide To investigate high risk type human papillomavirus (HPV) prevalence and incidence rates of cervical intraepithelial neoplasia (CIN) and their screen risk factors in women with different methods of screening.Methods:1137 residents, workers and service women aged 15-59 from Shenzhen city were investigated for cervical cancer in an epidemiology screening study.The high risk types of human papillomavirus of liquid-based cytology samples were tested by hybrid capture 2 (HC-Ⅱ) and liquid-based cytology test (LCT) was also performed at the same time. Women for HPV-positive with LCT ≥ atypical squamous cells of undetermined sign (ASCUS) or HPV-negative with LCT ≥ low grade squamous intraepithelial lesion (LSIL) were biopsied in colposcopy and then were examined by pathology. All data was managed by Foxbase. ?2 test and unconditional Logistic regression model were used for data analysis by SPSS 10.0.Results:1137 women were eligible in our research, the overall rates of HPV infection was 14.0%. HPV detection rates in residents, workers and service women were 14.1%,9.2%,18.9% respectively. HPV detection rates in workers group was significantly lower than that of service women and residents (P

Objective To investigate the regulatory effects of mifepristone and progesterone on the secretion of interleukin 6 (IL 6) by endometrial and endometriosis cells in vitro. Methods Primary cultures of eutopic and ectopic endometrial cells from 9 cases of endometriosis were exposed to mifepristone (10 -6 mol/L, 10 -4 mol/L) and progesterone (1?10 -7 mol/L, 1?10 -5 mol/L) respectively. IL 6 secretion was analyzed in the culture medium by enzyme linked immunosorbent assay (ELISA). Results Mifepristone inhibited the IL 6 secretion of ectopic endometrial cells, with the concentrations of IL 6 was (1 914 33?799 28) ?g/L in the 1?10 -6 mol/L group ( P 0 05). Conclusion The inhibitory effects on the secretion of IL 6 by ectopic and (or) eutopic endometrium may provide one of the cellular therapeutic mechanisms of mifepristone and progesterone on endometriosis.
