Objective:To analyze the influence factors of postoperative pregnancy in patients of endometriosis associated infertility after laparoscopy combined with hysteroscopy treatment.Methods:340 patients with endometriosis associated infertility who underwent laparoscopy combined with hysteroscopy treatment in Maternal and Child Health Care Hospital of Xiamen from April in 2012 to April in 2014 were followed up for 18 ～ 42 months to assess fertility outcomes.The relative factors of postoperative pregnancy rate were analyzed.Results:85.88％ (292/340) of patients were followed up,and the overall postoperative pregnancy rate was 56.51％.Among which the postoperative pregnancy caseswere 115 cases (39.38％),40 cases (13.70％),8 cases (2.74％),2 cases (0.68％) in the 1 ～ 6 months,7 ～ 12 months,13 ～ 24 months,25 ～ 42 months,respectively.There were significant differences among the four groups(x 2 =11.76,P ＜ 0.05).The multy-factors analysis showed that age ≥35,infertility time ≥3,r-AFS stage relatively high were risk factors of postoperative pregnancy(OR =10.45,3.03,3.74,P ＜0.05),and secondary infertility,applying ovarian stimulation treatment were the protective factors of postoperative pregnancy(OR =0.23,0.33,P ＜ 0.05).Conclusions:Laparoscopy combined with hysteroscopy treatment can increase postoperative pregnancy rate,and the best time to pregnancy is the first one year after treatment.The age ≥35,infertility time≥3,r-AFS stage relatively high are the important causes for the postoperative infertility,while applying ovarian stimulation treatment can promote pregnancy rate.

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: To determine the morbidity of cervical intraepithelial neoplasia 2+ (CIN2+ ) and CIN3+ of different human papillomavirus(HPV) subtype infection combined with different cytology status. Methods: The Shenzhen Cervical Cancer Screening Trial Ⅰ & Ⅱ (SHENCCASTⅠ&Ⅱ) are population-based cross-sectional cervical cancer screening studis conducted in Shenzhen and surrounding area from 2008 to 2010. A total of 12 097 women who aged 25-59 years were included in the analysis. All of these women were detected by liquid-based cytology test and several high-risk HPV-DNA tests. The ones with HPV positive or atypical squamous cells of undetermined sign (ASC-US) were sequentially conducted by cervical biopsy vaginoscopy. Finally, 10 805 samples with complete data of hybrid capture 2(HC2), the polymerase chain reaction-based matrix-assisted laser desorption/ionization time-of-flight assay (MALDI-TOF), HPV genotyping detection, cytology and pathology results were analyzed. Results: The top 6 infection rates of HR-HPV in CIN2+ and CIN3+ were HPV16, HPV52, HPV58, HPV33, HPV31, HPV18. The highest constituent ratio of cytology in CIN2+ and CIN3+ was high grade squamous intraepithelial lesion(HSIL). The morbidities of CIN2+ of patients infected with HPV16, HPV31, HPV58, HPV33, HPV18, HPV52 were 41.3%, 31.5%, 30.6%, 28.7%, 28.2%, 17.7%, respectively, while the morbidities of CIN3+ of those were 33.5%, 20.5%, 19.4%, 15.7%, 19.2%, 8.3%, respectively.The morbidities of CIN2+ in negative intraepithelial lesion or malignancy (NILM), ASC-US, low grade squamous intraepithelial lesion (LSIL), atypical squamous cell cannot exclude high-grade squamous intraepithelial lesion (ASC-H), high grade squamous intraepithelial lesion (HSIL), atypical glandular cell (AGC) samples were 0.4%, 6.9%, 11.1%, 36.4%, 82.0%, 16.7%, respectively, while the morbidities of CIN3+ of those were 0.2%, 3.1%, 4.2%, 22.7%, 64.8%, 0.0%, respectively. The morbidities of CIN2+ in NILM combined with HPV16, HPV18, HPV31, HPV33 infection were 12.6%, 13.3%, 15.8% and 11.5%, respectively, while the morbidities of CIN3+ of those were 10.3%, 11.1%, 7.9% and 7.7%, respectively.The morbidities of CIN2+ and CIN3+ in ASC-US combining with hrHPV infection were high, and the top 6 subtypes associated with high risk of CIN2+ were HPV31 (35.7%), HPV33 (26.9%), HPV16 (26.5%), HPV58 (22.4%), HPV52 (18.6%), HPV68 (15.4%), while those associated with high risk of CIN3+ were HPV16 (20.4%), HPV31 (14.3%), HPV33 (11.5%), HPV58 (8.6%), HPV68 (7.7%), HPV52 (5.8%). Conclusions Cytology combined with HPV genotyping detection can more effectively estimate the morbidity risks of CIN2+ and CIN3+ . Both high prevalence rates and high risks associated with CIN2+ and CIN3+ of HPV31, HPV33, HPV52 and HPV58 are observed. NILM and ASC-US status combined with these subtypes mentioned above are advised to be conducted by colposcopy.
