OBJECTIVE:Evaluate the significance of BMRT HPV assay viral load and its performance for secondary screening. METHODS:BMRT-HPV reports type-specific viral loads/10,000 cells. We tested 1,495 physician collected, stored specimens from Chinese Multiple-center Screening Trial (CHIMUST), that were positive by Cobas, SeqHPV, and/or Cytology (≥LSIL); and 2,990 age matched, negatives in a nested case control study. We explored the relationship between BMRT HR-HPV viral load and cervical lesions, determined alternative CIN2+ cut-points by ROC curve, and evaluated BMRT HR-HPV for primary / secondary cervical cancer screening. RESULTS:The viral loads of HPV16/18, 12 other subtypes HR-HPV and 14 HR-HPV were statistically different in all grades of cervical lesions (P0.05), specificity was higher than Cobas (84.8% vs 83.3%, 83.5% vs 82.0%, P0.05). However, the BMRT HR-HPV viral load combined with subtypes did not require cytology. CONCLUSION:BMRT is as sensitive as Cobas4800 for primary cervical cancer screening. BMRT HR-HPV viral load combined with subtypes can be used as a secondary strategy for cervical cancer screening, especially for areas with insufficient cytological resources.

Background/objectiveHuman papillomavirus (HPV) genotyping and cytology have been recommended for colposcopy triage, but it is unclear which combinations of high-risk HPV (hrHPV) types and cytology with various thresholds provide clinically useful information for the triage after primary HPV screening on self-collected samples.MethodChinese Multi-site Screening Trial (CHIMUST) database focused on self-collected samples was reviewed using the results of Cobas4800 HPV assay. Absolute risks of each genotype for cervical intraepithelial neoplasia 2 or worse/ 3 or worse (CIN2+/CIN3+) were calculated. Triage of atypical squamous cells of undetermined significance (ASCUS) or worse cytology was used as the comparator, and diagnostic accuracy for paired comparisons between algorithms was obtained using McNemar's test.ResultsA total of 10, 498 women were included, the overall prevalence of hrHPV, HPV16, HPV18, and Other hrHPV genotypes were 13.7%, 2.4%, 0.8%, and 10.5%, respectively. HPV16-positive women had the highest absolute risk among various genotypes for CIN2+/CIN3+ whether in normal or abnormal cytology (ASCUS or worse) and among all age groups. When compared with the comparator, combining HPV16 positivity and/or high-grade squamous intraepithelial lesion (HSIL) or worse yielded higher specificity (97.7% vs. 97.0%, pConclusionsTriage of HPV-positive women on self-collected samples by combining HPV16 or HPV16/18 genotyping with different thresholds of cytology could provide tradeoffs in sensitivity for detecting cervical lesions and colposcopy referral rates, and tailor management in various circumstances of clinical practice.

ObjectiveTo explore the relationship between the viral load reflected by the Ct value of Cobas 4800 HPV test and cervical lesions, and the effectiveness of the viral load for secondary triage of HPV-positive women.MethodsThe Chinese Multi-Center Screening Trial (CHIMUST) evaluated both self-collected samples and physician-collected samples from women, aged 30 to 59, who were screened for cervical cancer in 6 regions across China. Using physician collected samples, the relationship between the HPV-Ct values of different subtypes and the cervical lesions was analyzed. Then the combined use of the HPV-Ct values with the HPV subtypes was evaluated as a secondary screening algorithm for the women who were HPV positive.ResultsThe Ct values of HPV16 and 12 other HPV subtypes(12-type pool), tested with Cobas decreased with the progression of cervical lesion (HPV16: r = -0.429, P0.05). Compared with HPV16/18 and cytology (HPV16/18 positive and 12-type pool plus cytology ≥ ASC-US), the sequential secondary screening using HPV16/18 and the viral load of 12-type pool (cut-point HPV-Ct≤31) had equal sensitivities for CIN2+ and CIN3+ (83.1%vs.80.3%,100%vs.92.6%,P>0.05), with slightly lower specificities (96.2%vs.94.4%,96.5%vs.93.9%,PConclusionType-specific HPV viral load is closely related to cervical lesions severity. It is feasible and efficient to use HPV16/18 and the viral load of 12 other HPV subtypes (with cut-point HPV-Ct≤31) as the secondary screening for HPV positive women. This algorithm may be useful in low resource regions.

BackgroundCorrelation with HPV viral load and worsening cervical lesions had been reported, but its potential for triage after primary HPV screening has not been adequately explored, especially when combined with HPV-16/18 genotyping.ObjectiveTo evaluate combinations of human papillomavirus (HPV) viral load and genotyping for HPV-16/18 as secondary screening strategies.MethodsThe Shenzhen Cervical Cancer Screening Trial Ⅱ (SHENCCAST Ⅱ) database was re-analyzed to explore new screening algorithms using the results of Hybrid Capture 2 (HC2), Mass Array Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass spectrometry System (MALDI-TOF-MS) and the ThinPrep cytologic test (TCT) obtained by endocervical sampling.ResultsCompared with the recommended screening strategy of genotyping HPV-16/18 plus reflex to cytology, using viral load (10 RLU/CO as threshold) plus reflex to cytology resulted in less cytology but had a significantly higher sensitivity for cervical intraepithelial neoplasia 2+ (CIN2+)/CIN3+ without considerable changes in specificity and referral rates. Both of the strategy of using viral load ≥10 RLU/CO as cut-point for immediate colposcopy followed by triage genotyping HPV-16/18 for the other positive (≥1ConclusionsPrimary HPV screening with triage of HPV-positive women by a combination of viral load and genotyping for HPV-16/18 provides good balance between sensitivity and specificity, the number of tests required, and referral rates.

OBJECTIVES:Determine the ability of the Cobas 4800 assay to detect high-risk human papillomavirus (HrHPV) and high-grade cervical lesions when using cervico-vaginal samples applied to liquid medium and solid media cards compared to a direct cervical sample. METHODS:Two cervico-vaginal specimens (pseudo self-collected) were obtained from 319 women. One was applied to an iFTA Card (FTA) then the brush placed in liquid-based medium (LSELF); the other was applied to a new solid media: POI card (POI). The clinical performance of Cobas4800 assay using the three aforementioned specimens was compared to direct collected endocervical specimens in liquid media (LDOC). RESULTS:The overall agreements of HrHPV detection were 84.2% (LSELF vs. LDOC), 81.0% (FTA vs. LDOC), and 82.3% (POI vs. LDOC). LSELF, FTA and POI identified 98.0%, 79.6%, and 97.5% positive cases of LDOC. Sensitivity to identify CIN2+ were 98.4% (LSELF), 73.8% (FTA), 95.1% (POI), and 93.4% (LDOC) respectively. FTA had 78.1% and 90.4% agreement with the LSELF samples for all HrHPV and HPV16/18 detection respectively, while POI had 91.6% for both. CONCLUSIONS:Cobas4800 HPV test combined with cervico-vaginal specimens applied to both liquid media and POI solid card are accurate to detect HrHPV infection and high-grade cervical lesions as compared with direct endocervical samples in liquid media.

Objective To investigate the epidemiological characteristics of high-risk human papillomavirus(HR-HPV) infection based on vaginal self-collected samples. Study Design and Setting The pooled data of 3045 self-collected samples used for the analysis derived from four previous studies on cervical cancer screening(The Chinese Multi-Center Screening Trial, CHIMUST; The Shenzhen Cervical Cancer Screening Trial-2, SHENCCAST-2; The Chinese Cervical Cancer Prevention Study, CHIPCAPS; Pingshan trial, PINGSHAN)conducted across China by our team since 2011. These cases were evaluated for HR-HPV type prevalence relative to lesion grade and age. The occurrence of cervical intraepithelial neoplasia(CIN) with specific HPV types and the influence of co-infection is explored. Results The top three most common genotypes among the HR-HPV positives were HPV-52(23.4%), HPV-16(18.0%), and HPV-58(15.50%). For women with CIN2+, the most frequent genotypes were HPV-16, 58, 52, and 18 in sequence. HPV-16 accounted for the majority of CIN2/CIN3/Ca with attribution rate of 23.86%, 44.78% and 50.00% respectively. HPV-58 accounted for 19.48%, 16.79% and 13.46% respectively. CIN2+ was found in the following types most frequently: HPV-16(31.23%), HPV-33(24.03%), HPV-58(18.41%), HPV-31(11.76%), HPV-18(7.75%), and HPV-52(7.30%). HPV-16 showed preference for co-infection with HPV-52 and HPV-58. Conclusion The prevalence of HR-HPV infection based on self-sampling among women in China exhibited some unique epidemiologic features.

Background Congenital anatomic abnormalities of fallopian tubes and ovaries are rarely reported. Herein, we describe four cases of undescended ovary during laparoscopic surgery with abnormal anatomy of fallopian tube, yet without abnormal uterine development and urinary system abnormalities, which are analyzed by their clinical features and effects on reproductive function. Case presentation For the patients with undescended ovary, the location of unilateral or bilateral upper poles of the ovaries were usually much higher than that of the bifurcation of the common iliac vessel, and the fallopian tubes at the same side opened in the para-colonic sulcus. Among these four patients, two patients had primary infertility, one patient had tubal pregnancy rupture and bleeding, and one patient had uterine leiomyoma. The development of uterus was normal in all cases, and there was no abnormal development of urinary system. During the infertility examination, the fact that fallopian tubes lifted up in hysterosalpingography (HSG) might be regarded as an indicator of possible undescended ovary. The pelvic ultrasonography examination was of limited use in diagnosing undescended ovary. Conclusion Laparoscopy is the gold standard for the diagnosis of undescended ovary. When there is periodic post-sacral spinal pain, MRI or HSG can be used for diagnosis of undescended ovary.

Objective Self-sampling for human papillomavirus (HPV) testing is an effective option to increase the cervical screening coverage. How to best triage HPV-positive self-samples remains controversial. Here, we evaluated the performance of a novel p16INK4a immunocytology approach (p16) and HPV genotyping in triaging HPV-positive self-samples. Methods A cohort of 73699 women were screened via SeqHPV assay on self-samples. HPV-positive women who met any sequential positive result of HPV16/18 or VIA or p16 were referred for colposcopy. A triage strategy was considered favorable if the NPV for CIN3+ was ≥98%, combined with an improvement of sensitivity and specificity in comparison to the comparator, being the ‘ASC-US+’ triage and the guideline strategy (HPV16/18+ or ASC-US+). Results A total of 3510 HPV-positive women were included, 422 (12.0%) CIN2+ and 247 (7.0%) CIN3+ were identified. The positivity of p16 and ASC-US+ were 36.3% and 22.2%, respectively. p16 was more sensitive and less specific than ASC-US+ (P Conclusions Our findings indicate the promising utility of p16 immunocytology via adjusting the staining score or serving as an ancillary tool to liquid-based cytology or combining with genotyping for the triage of HPV-positive self-samples, which promotes the precise screening of cervical cancer.

Objective To compare the degree of agreement and consistency of urodynamic studies (UDS) with low urinary tract symptoms (LUTS) questionnaires for evaluating LUTS in cervical cancer patients following radical hysterectomy (RH) and pelvic lymphadenectomy. Methods From January 2012 to March 2015, 204 cervical cancer patients who underwent RH in 13 hospitals were evaluated using the Incontinence Questionnaire-Female Lower Urinary Tract Symptoms (ICIQ-FLUTS) and the Overactive Bladder Symptom Score (OABSS). Urodynamic tests were also performed on these patients during the same period. Results Study participants’ age ranged from 23 to 75 years, with a mean (standard deviation) of 48.0 ± 9.3 years. Using questionnaires, the prevalence of patients with LUTS symptoms, including storage symptoms, voiding symptoms, stress urinary incontinence (SUI) and overactive bladder (OAB) was 86.3%, 77.0%, 62.7%, 52.9% and 14.7%, respectively. For UDS, the corresponding prevalence was 89.7%, 70.1%, 66.7%, 46.6% and 13.2%, respectively. The diagnostic concordance of questionnaires and UDS for storage symptoms, voiding symptoms, SUI and OAB was 79.9%, 66.7%, 66.7%, 57.4% and 79.9%, respectively. For voiding symptoms, the correlation coefficient was 0.272, which was higher than that of storage symptoms, SUI and OAB. Conclusions In cervical cancer patients who have undergone RH, there was a moderate degree of agreement between UDS and symptom questionnaires in evaluating LUTS, but the consistency was poor. Medical personnel should be adequately trained in UDS to ensure LUTS are adequately diagnosed in patients.

Background Systemic sclerosis (SSc) is a multisystem rheumatic disease. Orofacial manifestations are commonly in SSc but maybe usually ignored and overshadowed by other systemic complications. Multiple comparative studies have been conducted to investigate the possible links between SSc and oral manifestations. The present study aimed to investigate the oral health status in patients with SSc. Methods Pubmed, Embase, Web of Science, and Scopus were searched up to July 2020. Following outcomes were evaluated: Probing depth (PD), Attachment loss (AL), Bleeding on probing (BOP), Number or percentage of Sites with PD ≥ 4 mm, Prevalence of periodontitis, Number of teeth, Decayed Teeth, Missing teeth, Filled teeth, DMFT index, and the interincisal distance. Newcastle-Ottawa Scale (NOS) were applied for quality assessment. The statistical analysis was processed using the software STATA. Results 11 eligible studies were included. The maximum interincisor distance was significantly restricted in SSc patients (SMD − 1.061; 95 %CI [− 1.546, − 0.576]; Z = 4.29, P = 0.000).The prevalence of Periodontitis (OR 7.007; 95 %CI [3.529, 13.915]; Z = 5.56, P = 0.000), PD (SMD 3.101; 95 %CI [1.374, 4.829]; Z = 3.52, P = 0.000), AL(SMD 2.584; 95 %CI [0.321, 4.846]; Z = 2.24, P = 0.025), sites with PD ≥ 4mm (SMD 2.071 ; 95 %CI [0.267, 3.875]; Z = 2.25, P = 0.024) and the number of decayed teeth (SMD, 0.186; 95 %CI [0.007, 0.365]; Z = 2.04, P = 0.041) were increased significantly in SSc population in comparison with the controls. Conclusions SSc patients have limited mouth opening, higher periodontitis prevalence, and worse periodontal status, as well as an increased number of decayed teeth. Routinely oral hygiene instruction and initial periodontal treatment is recommended for SSc patients.

Background For cervical cancer screening, routine cytology has a high specificity but a lower sensitivity. In older women, atrophy, which may mimic HSIL, presents a diagnostic challenge. p16 is a widely used biomarker for histological diagnosis of HSIL. Our objective was to evaluate PathCIN® p16INK4a immunocytology in identification of high grade dysplasia vs. benign atrophy. Methods As part of a multi-center screening program, 3351 women were co-tested by p16 immunocytology. Among women referred for colposcopy on basis of cytology and high-risk HPV status, those with atrophy were older than the population screened (52 vs. 43 years). Cases from older women with atrophy (n = 116) and controls without atrophy (n = 47) were identified by re-examination of Pap smears. The detection of CIN2+ was compared for p16, cytology and HR-HPV results. Results The sensitivity of routine cytology (≥LSIL) was much lower for cases with atrophy (17%) than non-atrophic cases (75%). The sensitivity of p16 immunocytology and of HR-HPV testing was high (88%–100%) both with and without atrophy. The specificity of routine cytology (≥LSIL) was higher for cases with atrophy (79%) than non-atrophic cases (38%). The specificity of p16 immunocytology was high (88–95%) and the specificity of HR-HPV testing was low (31%–33%) both with and without atrophy. Combining p16 with HPV testing and/or routine cytology had no benefit, as compared to p16 staining alone. Conclusions p16 immunocytology compares favorably with routine cytology and HPV testing in the differential diagnosis of HSIL and benign atrophy. It is more sensitive than cytology for atrophic specimens, and is more specific than HPV testing. p16 immunocytology may decrease the need for colposcopy referrals and could be a useful tool for early detection of cervical cancer in peri- and post-menopausal women, who are more likely to have HSIL coexisting with atrophy.

Objective To assess the prevalence and distribution of HPV genotypes among Chinese Han women, and to explore the risk of high-grade cervical lesions associated with individual hr-HPV genotypes. Methods Genotyping and histopathology data from the Chinese Multi-Center Screening Trial (CHIMUST) and its pilot screening trial, from 6 regions across mainland China, were re-analyzed. The data from physician- and self-collected samples from 10,867 Chinese Han women (ages 30–69) were used to determine the prevalence and distribution of hr-HPV and to explore the risk association between hr-HPV genotypes and precancerous lesions. Results 9.2% of the study population tested hr-HPV positive in physician-collected sample. The prevalence varied regionally from the lowest in Guangdong (6.3%) to the highest in Inner Mongolia (13.0%). The most prevalent genotypes found were HPV-52 (21.7%), HPV-16 (19.2%), HPV-58 (15.0%), HPV-39 (8.9%), and HPV-51 (8.2%). The overall odds ratios for CIN2+ and CIN3+ for the presence of HPV-16 was 58.6 (95% CI 39.2–87.5) and, 91.6 (95%CI 54.3–154.6), respectively and remained the highest odds ratio for CIN3+ in all 6 regions. Conclusion Geographical variation exists in the prevalence and distribution of hr-HPV in mainland China. HPV-16/52/58 were the most prevalent genotypes, and HPV-16 had the highest risk for high-grade cervical lesions. Trial registration CHIMUST, Registration number: ChiCTR-EOC-16008456.

Objective The aim of the study was to evaluate the Cobas 4800 Assay and the SeqHPV Assay with self (S) and direct (D) cervical samples in the Chinese Multicenter Screening Trial (CHIMUST). Materials and methods The CHIMUST is a large population-based multicenter clinical trial, and 10,885 women aged 30-59 years from 15 sites in 7 provinces with no cervical cancer screening for 3 years were eligible. All participating women contributed one self-collected sample (S) and 1 physician-collected endocervical sample (DL). The self-collected sample was first applied to the solid media transport card (SS), and then, the brush placed in 6 mL of ThinPrepSolution (SL). All samples were tested with Cobas 4800 and SeqHPV high-risk HPV assays. Patients human papillomavirus positive (self or direct) were recalled for colposcopy and biopsies. Results A total of 10,399 women had complete data. The mean age was 43.9 years. A total of 1.4% (142/10,399) had cervical intraepithelial neoplasia (CIN) 2+ and 0.5% (54/10,339) had CIN 3+. In the liquid specimens, the overall HPV infection rates were 10.8% for Cobas and 10.9% for SeqHPV in D sample, and 13.7% for Cobas and 11.6% for SeqHPV in SL sample, respectively. The sensitivity of Cobas-DL, Cobas-SL, SeqHPV-DL, and SeqHPV-SL for CIN 2+ was 95.07%, 95.07%, 94.33%, and 96.48%, respectively. The specificity of Cobas-DL, Cobas-SL, SeqHPV-DL, and SeqHPV-SL for CIN 2+ was 90.38%, 87.35%, 90.21%, and 89.53%, respectively. There were no differences in sensitivity when applying the 2 assays to both self- and directly collected samples in liquid transport media (p > .05). Conclusions Both Cobas and SeqHPV screening assays using both self-collected and directly endocervical collected specimens demonstrate similar sensitivity for the detection of CIN 2+ and CIN 3+.

Background The solid transport media is a small size card that allows fast, easy DNA extraction from a variety of biological samples. In 2016 we developed a solid media transport card; for that pilot study to control the self-collection we used a pseudo-self-collection technique. The current study expands this prior work using true self-collections and only the POI card, and aims to evaluate the solid media transport card to detect HR-HPV in self-samples compared to liquid transport media. Methods Ten thousand eight hundred eighty-five women between the ages of 30–59 with no screening for 3 years were enrolled. The self-collected sample was first applied to a new solid media transport card (Labeled as SC) then the brush placed in 6 ml ThinPrep liquid (Labeled as SL). Then a physician collected a direct endocervical specimen into ThinPrep liquid (Labeled as DL). Samples were tested with Cobas 4800 and the SeqHPV NGS assay for HR-HPV. Patients positive on any test were recalled for colposcopy and biopsy. Results Ten thousand three hundred thirty-nine participants had complete data. The mean age was 43.9 years. CIN 2+ rates were 1.4% (142/10339). The agreement in HPV detection between the two different self-sample collection media was also good (Cobas HPV kappa = 0.86; SeqHPV kappa = 0.98). Tested with Cobas, the sensitivity of Cobas-SL and Cobas-SC for CIN 2+ was95.07 and 94.37%; and for CIN3+ was 96.30, 96.30% respectively. The specificity of Cobas-SC, and Cobas-SL for CIN2+ was 88.74 and 87.35%; for CIN3 was 88.04and 86.65% respectively. Tested with SeqHPV, the sensitivity for CIN2+ of Seq-SC and Seq-SL was 95.77 and 96.48%; for CIN3+, both the SC and SL specimens had a sensitivity of 100%. The specificity for CIN2+ of Seq-SC and Seq-SL was 89.54 and 89.53%; for CIN3+ was 88.84,88.82% respectively. For both HR-HPV assays, the sensitivities were similar for the two self-sample media (SC vs SL, p = 1.00). Conclusions The solid transport card for collecting vaginal self-samples as accurate as liquid transport media assayed by two different PCR based HR-HPV tests. The solid transport media is a suitable medium for collecting and storing vaginal self-samples.

Background: This study aimed to evaluate three different patterns of cervical cancer screening strategies for detection of cervical diseases. Methods: In total, 10,186 women aged 21–70 years attending cervical screening program were recruited and cotested by human papillomavirus (HPV) assays and cytology. Three-year histological follow-up data was recorded on women with abnormal screening results, and six clinically common screening algorithms were evaluated. Results: Significantly better protection against cervical intraepithelial neoplasia 2 or worse (CIN2+) at three-year follow-up was associated with a negative HPV result than by normal cytology at baseline. HPV screening was more sensitive and less specific than cytology screening. Moreover, HPV screening with HPV16/18 and reflex cytology (atypical squamous cells of undetermined significance [ASCUS] threshold) showed a similar sensitivity (94.6% vs. 98.2%, p = 0.125) and a superior specificity as compared to cotesting reflex HPV16/18 and cytology (ASCUS threshold) for CIN2+ (95.8% vs. 95.1%, p < 0.0001), achieving a colposcopy referral rate of 5.4%, and consuming 4.8 colposcopies and 4.4 cytology tests to find one CIN2+. Conclusions: HPV screening with triage of HPV-positive women by HPV16/18 genotyping and cytology provided a good equilibrium between screening effectiveness, the number of cytology tests required, and referral rates; HPV testing was similar in sensitivity to cotesting and safer than cytology, thus especially suitable for large population-based screening programs.

Aim To compare thermocoagulation and cryotherapy for treatment of high‐grade cervical intraepithelial neoplasia (CIN). Methods From May 2017 to May 2018, women with CIN2/3 were randomized to thermocoagulation or cryotherapy at Peking University Shenzhen Hospital. Follow‐up at 4 and 8 months included cytology and human papillomavirus (HPV) testing. Women who were HPV‐positive or had atypical squamous cells of undetermined significance or higher‐grade disease underwent colposcopy/biopsy. Results Among 149 women enrolled, 74 were randomized to thermocoagulation, and 75 to cryotherapy (excluded four were immediately referred for thermocoagulation due to large lesions). At follow‐up, there was no difference between the thermocoagulation and cryotherapy groups in HPV‐negative (4/8 months: 72.5%/86.2% vs 68.6%/80.6%) and pathology‐negative (97.1%/98.5% vs 94.3%/92.3%) rates (all P > 0.05). The cytology‐negative rate was similar for thermocoagulation and cryotherapy at 4 months (79.7% vs 78.9%, P > 0.05), but higher for thermocoagulation at 8 months (100% vs 88.7%, P

Purpose When used for cervical cancer primary screening, liquid-based cytology (LBC) has a high specificity but a low sensitivity. For histological diagnosis of high-grade lesions, p16INK4a immunostaining has proven to be useful. Therefore, our objective was to evaluate the use of p16INK4a immuno-cytology as a primary screen and a secondary screen after primary high-risk human papillomavirus (hrHPV) screening or LBC screening. Methods A total of 1197 cytology slides were immuno-stained using automatic p16INK4a staining system (PathCIN®p16INK4a) in two studies from cervical screening programs. In the primary screening study, 875 slides were randomly selected and analyzed for p16INK4a. In the secondary screening study, 322 of the remaining slides were chosen by virtue of being HPV 16/18+, other hrHPV+/LBC≥ASC-US, or HPV-negative/LBC ≥LSIL. The sensitivity and specificity for detection of cervical intraepithelial neoplasia 2/3 or worse (CIN2+/CIN3+) were compared based on p16INK4a, LBC and HPV test results. Results In combining two studies, there were 431 cases with biopsy pathology. They included 83 cases with CIN2+ and 41 cases with CIN3+. The p16 positivity rate increased with pathologic and cytologic severity (P

Endometriosis (EMS) is a multifactorial disease that affects 10%–15% women of reproductive age and is associated with chronic pelvic pain and infertility. The pathogenesis of EMS has not been consistently explained until now. In this study, we involved 36 endometriosis patients and 14 control subjects who performed laparoscopic surgery due to gynecological benign tumor. The samples from lower third of vagina (CL), posterior vaginal fornix (CU), cervical mucus (CV), endometrium (ET) and peritoneal fluid (PF), were collected and sequenced by 16S rRNA amplicon. The continuous change of the microbiota distribution was identified along the reproductive tract. The flora in lower reproductive tract (CL, CU) were dominated by Lactobacillus. Significant difference of the community diversity began showing in the CV of EMS patients and gradually increased upward the reproductive tract. It indicates the microbiota in cervical samples is expected to be an indicator for the risk of EMS. This study also highlights the decreasing of Lactobacillus in vaginal flora and the increasing of signature Operational Taxonomic Units (OTUs) in transaction zone (CV) and upper reproductive tract (ET, PF) of EMS patients, which reflect the alteration of microbial community associated with EMS, participation of specific colonized bacteria in the EMS pathogenesis and relationship between microbiota and development of disease.

Psoriasis is a chronic, recurrent inflammatory autoimmune skin disease. Although its etiology and pathogenesis are complex and multifarious, it has been proved to be closely related to dysregulation of immune cell function as well as keratinocyte proliferation/differentiation. Our previous study demonstrated that miRNA-210 (miR-210) plays an important role in the formation of skin lesions and immune imbalance in psoriasis. Here, we developed a biomimetic reconstituted high-density lipoprotein (rHDL) nanocarrier gel containing miR-210 antisense (NG-anti-miR-210) to investigate its effect on imiquimod (IMQ)-induced psoriasis-like dermatitis in mice. We found that topical treatment with NG-anti-miR-210 significantly decreased the expression of miR-210 in both the skin lesions and splenic CD4+ T cells from IMQ-induced psoriasis-like mouse models and ameliorated the dermatitis in terms of the erythema, scales, acanthosis and dermal inflammatory cell infiltration in IMQ-induced mice. In addition, the proportion of T-helper (Th)1 and Th17 cells in dermal and splenic cells of IMQ-treated mice were decreased by application of NG-anti-miR-210, accompanied by decreased interleukin-17A and γ-interferon mRNA levels. Therefore, our data demonstrate that topical inhibition of miR-210 delivered by rHDL nanocarrier effectively alleviates the psoriasis-like inflammation in mice and provides a potentially effective topical drug for psoriasis.

In the past decade, we have witnessed considerable developments in understanding the roles and functions of miRNAs. In parallel, the identification of alterations in miRNA expression in inflammatory disease indicates their potential as therapeutic targets. Pharmacological treatments targeting abnormally expressed miRNAs for inflammatory diseases are not yet in clinical practice; however, some small compounds and nucleic acids targeting miRNAs have shown promise in preclinical development. Here, we focus on recent advances in understanding miRNA deregulation in inflammatory diseases and provide an overview of the current development of miRNA-based therapeutics in these diseases with an emphasis on newly discovered miRNA therapeutic targets.

OBJECTIVE The aim of the study was to assess whether lower proportions of cervical intraepithelial neoplasia 2+ diagnosed by random biopsy are from lower cut points defining an abnormal colposcopic impression or obtaining only one random biopsy when colposcopic impression is normal. METHODS We compared colposcopy experiences within Shanxi Province Cervical Cancer Screening Study (SPOCCS) (n = 1,383) and Shenzhen Cervical Cancer Screening Trial (SHENCCAST) (n = 631), which had instructive differences in the cut point defining an abnormal colposcopic impression. RESULTS The proportion of CIN 2+ diagnosed by random biopsy in SPOCCS (35.0%, 141/403) was higher than SHENCCAST (18.4%, 35/190, p < .001). Quadrant-specific receiver operating characteristic curves for diagnosis of CIN 2+ by colposcopic impression in SPOCCS and SHENCCAST were similar; a lower cut point for an abnormal colposcopic impression in SHENCCAST resulted in lower proportion of CIN 2+ diagnosed by random biopsy. Normal colposcopic impression was found in 85.1% (120/141) of cases of CIN 2+ diagnosed by random biopsy in SPOCCS and in 57.1% (20/35) of such cases in SHENCCAST. Of CIN 2+ diagnosed by random cervical biopsy with normal colposcopic impression, one cervical quadrant was involved with CIN 2+ in 66.7% (80/120) of colposcopies in SPOCCS and 80% (16/20) of colposcopies in SHENCCAST. CONCLUSIONS Colposcopy series with higher proportions of CIN 2+ diagnosed by random biopsy likely have more stringent cut points defining an abnormal colposcopic impression and have more random biopsies when the colposcopic impression is normal. At colposcopy, we advise multiple biopsies of all acetowhite epithelium or multiple random biopsies to increase the sensitivity of colposcopy.

Background Self-sampling for human papillomavirus (HPV) testing is a feasible option to improve the cervical screening coverage. However, an ideal triage method for HPV-positive self-samples does not yet exist. The aim of this study was to explore the utility of HPV genotyping and p16INK4a immunostaining (p16) in triaging HPV-positive self-samples, focusing on HPV-positive, cytology-negative (HPCN) women. Methods A total of 73,699 women were screened in a cervical screening project in China via SeqHPV assay on self-samples. HPV-positive women were called-back and collected cervical sample for p16 immunostaining and liquid-based cytology, those who met any result of HPV16/18+ or visual inspection with acetic acid (VIA) + or p16+ were referred for colposcopy, and HPCN women with adequate data on p16 and pathology were analyzed. A triage strategy was considered acceptable if the negative predictive value (NPV) for cervical intraepithelial neoplasia 3 or worse (CIN3+) was 98% or more, combined with an improvement of sensitivity and specificity for CIN2+/CIN3+ in reference to the comparator, being HPV16/18 + . Results A total of 2731 HPCN women aged 30–64 years were enrolled, 136 (5.0%) CIN2+ and 53 (1.9%) CIN3+ were detected. Five triage strategies met the criteria: p16+; HPV16/33+; ‘HPV16+ or HPV33/58/31/35+&p16+’; ‘HPV16/33+ or HPV58/31/35+&p16+’; HPV16/18/31/33/45/52/58 + & p16+. These strategies required less or similar colposcopy referrals, and less colposcopies to detected one case of CIN2+/CIN3+, achieving favorable false positive (negative) rates to the comparator. Among them, p16 staining detected 83.1% (79.2%) of underlying CIN2 + (CIN3+) in HPCN women. Moreover, three triage strategies were favorable in sensitivity and/or specificity to the ‘HPV16/33+’ strategy: p16+; ‘HPV16+ or HPV33/58/31/35 + &p16+’; HPV16/18/31/33/45/52/58 + &p16 + . Conclusions Genotyping for HPV16/33 could be utilized to optimize the management of HPCN women. Moreover, p16 immunostaining, either alone or combined with extended genotypes, is more effective than HPV genotypes alone in the triage of HPCN women.

As a subgroup of CD4+ T helper cells, follicular helper T (Tfh) cells provide help to germinal center B cells and mediate the development of long-lived humoral immunity. Dysregulation of Tfh cells is associated with several major autoimmune diseases. Although recent studies showed that Tfh cell differentiation is controlled by the transcription factor Bcl6, cytokines, and cell-cell signals, limited information is available on the proteome and post-translational modifications (PTMs) of proteins in human Tfh cells. In the present study, we investigated quantitative proteome and acetylome in human naive CD4+ T cells and in vitro induced Tfh (iTfh) cells using the tandem mass tag (TMT) labeling technique, antibody-based affinity enrichment, and high-resolution liquid chromatography-mass spectrometry (LC-MS)/mass spectrometry (MS) analysis. In total, we identified 802 upregulated proteins and 598 downregulated proteins at the threshold of 1.5-fold in iTfh cells compared to naive CD4+ T cells. With the aid of intensive bioinformatics, the biological process, the cellular compartment, the molecular function, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway, and protein–protein interaction of these differentially expressed proteins were revealed. Moreover, the acetylome data showed that 22 lysine (K) acetylated proteins are upregulated and 26 K acetylated proteins are downregulated in iTfh cells compared to the naive CD4+ T cells, among which 11 differentially acetylated K residues in core histones were identified, indicating that protein acetylation and epigenetic mechanism are involved in regulating Tfh cell differentiation. The study provides some important clues for investigating T cell activation and Tfh cell differentiation.

Background: Women with diffuse adenomyosis frequently have severe symptoms, including dysmenorrhea and infertility. Though it is beneficial for long-term health if the uterus can be preserved, there is no prospective investigations to assess lesion removal, symptom alleviation and even gestations after uterus-preservative surgery. Methods: We applied self-optimized PUSH surgery for 146 patients with diffuse adenomyosis and conducted 2 to 11-year follow-up for 114 patients. We detailed procedures in uterine incision , excision of the lesion, uterus reconstruction, solutions for removing giant lesions, and assessed the clinical efficacy and fertility in follow-up. Findings: The average size and volume of the patients’ uterus decreased significantly after PUSH surgery. Operation-related complications occurred in 2.7% (4/146) of the patients. Among 114 patients who had been investigated for ≥2 years, 107 (93.9%, analytic group) had detailed records that was needed to evaluate the long-term outcomes. In analytic group, 5 cases recurred and 95.3% (102/107) of the patients had normal uterine size two years after surgery. The visual analogue scale (VAS) for dysmenorrhea significantly decreased in 102 cases, from 9.35±1.25 to 0.34±0.76 and 0.56±1.06 in the first and second year after surgery, respectively. Additionally, 97.7% of the 86 patients with severe menorrhagia had their symptoms ameliorated in the second year of follow-up. Of the 23 patients who desired for pregnancy and stopped contraception for ≥2 years, 13 (13/23,57%) individuals conceived with17 pregnancies. Twelve patients had 15 intrauterine pregnancies and 7 patients had 8 living fetus. No uterine rupture or severe complications were found in all gestations. Interpretation: This study demonstrate good performance of PUSH surgery in removing uterine lesions, ameliorating menorrhagia and preserving fertility for women with diffuse adenomyosis.

Objective: To investigate the epidemiological characteristics of high-risk human papillomavirus (HR-HPV) infection and the genotype distribution of HR-HPV in different regions of China using self-collected vaginal samples. Study Design and Setting: A total of 20,136 women aged 30–59 years were recruited from 13 provinces in China from September 2018 to July 2020. All participants registered, signed electronic informed consent, and filled in individual information voluntarily using an internet-based cervical cancer screening platform, then received a self-sampling kit. The samples were tested for 14 types of HR-HPV using the SeqHPV and BMRT HPV PCR assays. Results: After excluding 33 samples because of labeling errors or insufficient amounts of HPV DNA in specimens, 20,103 women (99.84%) were ultimately analyzed with a mean age of 44.31 ± 7.70 years. The overall prevalence of HR-HPV infection was 13.86%. The vast majority of HR-HPV (77.18%) were still a single type. Among 13 regions, Inner Mongolia had the highest prevalence (21.55%), while the lowest prevalence was in Jilin (9.51%). The following factors were found to be significantly associated with HR-HPV infection: age, sexual behavior, irregular screening, and economic level. The top five most common HR-HPV subtypes were HPV-52 (3.42%), HPV-58 (2.29%), HPV-16 (2.17%), HPV-39 (1.35%), and HPV-51 (1.30%), while HPV18 (0.86%) was the less prevalent. The prevalence of infection with a single type of HR-HPV was 10.70% and the prevalence of infection with multiple types was 3.16%. The prevalence curve of age-specific HR-HPV was V-shaped from 30 years to 59 years, with a lower prevalence observed in women aged 40–44 years (12.35%) and infection subsequently increasing with age. The proportion of women aged 30–34 years with HPV-16 (17%) was much higher than the proportion in other age groups, and the prevalence of HPV-18 (6%) was highest in women aged 45–49 years. The undeveloped regions (according to the GDP) had the highest prevalence of specific combinations of HR-HPV subtypes, of which HPV-16/HPV-18 infections decreased with increasing GDP. Furthermore, a more number of sexual partners and age of first sexual intercourse

During COVID-19 outbreak hospitals were congested and infliximab was interrupted. Thus, we performed this observational study to understand the consequent burden of complications in these special cluster of psoriatic patients. We followed up 56 psoriatic patients who were receiving Infliximab treatment by telephone. The majority of patients had lesions exacerbation, accompanied by anxiety emotion. It is suggested that reserving common drugs for psoriasis at home is necessary. Besides, telemedicine should be advocated as a main medical visit mode during the outbreak of COVID-19.

Objective The aim of this research was to evaluate independently the performance of a new isothermal amplification assay for cervical cancer screening compared to two previously validated PCR-based assays and histologic endpoints. Methods This is a sub-study from the Chinese multi-center screening trial (CHIMUST). The self-collected and clinician-collected specimens stored in PreservCyt at − 4 °C from 6042 women with complete data were tested with the AmpFire assay. These specimens had been previously tested with Cobas and SeqHPV assays. In the primary study all patients with an abnormal test were referred to colposcopy where all had directed and/or random biopsies plus ECC. No additional patients were called back based on the AmpFire results. Results 6042/6619 women had complete data (mean age 44.1). There were 57 cases of CIN 2, 35 cases of CIN 3 and 2 cancers. The sensitivity for CIN2+ and CIN3+ were similar among the three assays (both direct and self-collected). For the specificities in all categories (CIN2+/CIN3+ and self and direct collection), isothermal amplification assay was either equal to or more specific than Cobas but consistently less specific than SeqHPV. Conclusion The AmpFire HPV assay showed similar sensitivity to Cobas and SeqHPV for CIN2+ and CIN3+ on both self and clinician-collections (P>0.05), with good specificity. The speed, low cost, and simplicity of this assay will make it particularly suited for low and middle resource settings. Its accuracy with self-collection makes it applicable for mass screening programs.

Although the original purpose of the systemic lupus erythematosus (SLE) classification criteria was to distinguish SLE from other mimic diseases, and to facilitate sample selection in scientific research, they have become widely used as diagnostic criteria in clinical situations. It is not known yet if regarding classification criteria as diagnostic criteria, what problems might be encountered? This is the first study comparing the three sets of classification criteria for SLE, the 1997 American College of Rheumatology (ACR’97), 2012 Systemic Lupus International Collaborating Clinics (SLICC’12) and 2019 European League Against Rheumatism/American College of Rheumatology (EULAR/ACR’19), for their ability to distinguish patients with SLE from patients with pure mucocutaneous manifestations (isolated cutaneous lupus erythematosus without internal disease, i-CLE) in the lupus disease spectrum. 1,865 patients with SLE and 232 patients with i-CLE were recruited from a multicenter study. We found that, due to low specificity, none of the three criteria are adept at distinguishing patients with SLE from patients with i-CLE. SLICC’12 performed best among the original three criteria, but if a positive ANA was removed as an entry criterion, EULAR/ACR’19 would performed better. A review of previous studies that compared the three sets of criteria was presented in this work.

Objective The performance of Cobas4800 cycle threshold value (Ct-value, reflecting viral load) combined with human papillomavirus (HPV) 16/18 genotyping was explored as a method of risk stratification to triage patients after primary HPV screening of self-collected samples. Methods The Chinese Multi-site Screening Trial database was reviewed, with focus on self-collected samples, using the results of Cobas4800 HPV assay. Quartiles of Ct-values of each genotype were used for grouping and developing screening algorithms. Diagnostic accuracy for paired comparisons between algorithms was obtained using McNemar’s test. Results A total of 10,498 women were included. The Ct-values of HPV16 and other high-risk HPV were inversely correlated with the severity of cervical lesions ( p 0.05), and resulted in a slightly lower specificity than the latter two algorithms (92.6% vs. 97.4% and 95.4% respectively for CIN2+, p Conclusions HPV viral loads reflected by Ct-values are associated with the severity of cervical lesions. Ct-values with an appropriate cut-off of 33.7, combined with HPV16/18 genotyping, represent a promising triage of HPV-positive women particularly for self-collected samples.

Background Congenital anatomic abnormalities of fallopian tubes and ovaries are rarely reported. Herein, we describe four cases of abnormal ovarian descent during laparoscopic surgery with abnormal anatomy of fallopian tube, without abnormal uterine development and urinary system abnormalities. These cases are analyzed by their clinical features and their effects on reproductive function. Case presentation For patients with undescended ovary, the upper part of the unilateral/bilateral ovary decline was much higher than that of the common iliac vessel bifurcation, and the fallopian tube on the same side opened in the para-colonic sulcus. Among four patients, two cases had primary infertility, one case had tubal pregnancy rupture and bleeding, and one case had uterine leiomyoma. The development of uterus was normal in all the four patients, and there was no abnormal development of urinary system. During the infertility examination, hysterosalpingography (HSG) suggestion of oviduct lift was a sign for possible undescended ovarian. The pelvic B-ultrasound examination was limited to discover ovarian maldescent. Conclusion Laparoscopy was the gold standard for the diagnosis of poor ovarian decline. When B-ultrasound prompts one-sided or double-sided "ovary display is unclear" or detects "shrinking small ovaries", it might be ovarian maldescent. When there is periodic post-sacral spinal pain, MRI positioning or HSG can be used for diagnosis.

Background: The IL-23/17 axis plays central role in the pathogenesis of several immune-mediated inflammatory diseases (IMIDs). IL-23/17 antagonists showed significant improvement in the treatment for psoriasis and other IMIDs, including psoriasis(PSO), psoriatic arthritis(PsA), rheumatoid arthritis(RA) and ankylosing spondylitis(AS).Objective: To assess the safety of IL-23/17 antagonists therapy on patients with psoriasis and other IMIDs.Methods: Pooled analysis from thirty-nine placebo-controlled randomized clinical trials (RCTs) of IL-23/17 axis antagonists for IMIDs. Incidences of adverse events (AEs), serious adverse events (SAEs) and AEs of interest were applied to evaluate the safety profile.Result: A Total of 15967 patients were exposed to IL-23/17 axis antagonists. The proportions of patients suffered at least one AE in antagonists group and placebo-control group are 67.5% and 51.1% respectively. Incidence of SAE was increased in patients treated with IL-23/17 axis antagonists compared to patients given placebo (relative risk 2.03; 95% CI, 1.62, 2.56). Incidence of AEs of interest were all increased in patients treated with IL-23/17 axis antagonists compared to patients given placebo.Conclusion: In this analysis, we found increased risk of AEs, SAEs, nervous system disorder, cardiovascular disorder and hypertension among patients with IMIDs treated with IL-23/17 axis antagonists.

On Nov 17, 2020, WHO launched a global initiative to accelerate the elimination of cervical cancer through the implementation of HPV vaccination, cervical cancer screening and treatment for precancer and cancer. China has the largest burden of cervical cancer in the world, but only has a national cervical cancer screening program in rural areas since 2009. Here, we aimed to evaluate the effectiveness and cost-effectiveness of cervical cancer screening in urban China, using Shenzhen City as an example.We use an extensively validated platform ('Policy1-Cervix'), calibrated to data from Shenzhen city and Guandong Province. We evaluated a range of strategies that have previously been implemented as pilot studies in China, or recommended as guidelines within China and globally, spanning primary HPV, cytology and co-testing strategies. We additionally considered alternate triaging methods, age ranges and screening intervals, resulting in 19 algorithms in total.Of the 19 strategies considered, the most effective approach involved primary HPV testing. At 3- to 10-yearly intervals, primary HPV testing reduced the age-standardized cancer mortality rate by 37-71 %. The most cost-effective strategy was 5-yearly primary HPV testing with partial genotyping triage for ages 25-65, discharging to 10-yearly screening for low-risk women (ICER = US$7191/QALYS using 2018 costs; willingness-to-pay threshold1xGDP [US$9771]). This strategy gave an incidence and mortality reduction of 56 % and 63 %, respectively. This remained the most cost-effective strategy under most conditions in sensitivity analysis.Primary HPV testing would be cost-effective in Shenzhen and could more than halve cervical cancer incidence rates to 6 per 100,000 over the long term. In order to achieve rates below 4 per 100,000, the elimination threshold set by the World Health Organization, vaccination will likely also be necessary.

Objective Evaluate the significance of BMRT HPV assay viral load and its performance for secondary screening. Methods BMRT-HPV reports type-specific viral loads/10,000 cells. We tested 1,495 physician collected, stored specimens from Chinese Multiple-center Screening Trial (CHIMUST), that were positive by Cobas, SeqHPV, and/or Cytology (≥LSIL); and 2,990 age matched, negatives in a nested case control study. We explored the relationship between BMRT HR-HPV viral load and cervical lesions, determined alternative CIN2+ cut-points by ROC curve, and evaluated BMRT HR-HPV for primary / secondary cervical cancer screening. Results The viral loads of HPV16/18, 12 other subtypes HR-HPV and 14 HR-HPV were statistically different in all grades of cervical lesions (P0.05), specificity was higher than Cobas (84.8% vs 83.3%, 83.5% vs 82.0%, P0.05). However, the BMRT HR-HPV viral load combined with subtypes did not require cytology. Conclusion BMRT is as sensitive as Cobas4800 for primary cervical cancer screening. BMRT HR-HPV viral load combined with subtypes can be used as a secondary strategy for cervical cancer screening, especially for areas with insufficient cytological resources.

Epigenetic modifications affect the differentiation of T cell subsets and the pathogenesis of autoimmune diseases, but many mechanisms of epigenetic regulation of T cell differentiation are unclear. Here we show reduced expression of the transcription factor RFX1 in CD4+ T cells from patients with systemic lupus erythematosus, which leads to IL-17A overexpression through increased histone H3 acetylation and decreased DNA methylation and H3K9 tri-methylation. Conditional deletion of Rfx1 in mice exacerbates experimental autoimmune encephalomyelitis and pristane-induced lupus-like syndrome and increases induction of Th17 cells. In vitro, Rfx1 deficiency increases the differentiation of naive CD4+ T cells into Th17 cells, but this effect can be reversed by forced expression of Rfx1. Importantly, RFX1 functions downstream of STAT3 and phosphorylated STAT3 can inhibit RFX1 expression, highlighting a non-canonical pathway that regulates differentiation of Th17 cells. Collectively, our findings identify a unique role for RFX1 in Th17-related autoimmune diseases., Th17 cells are a common pathogenic effector cell in autoimmune inflammatory diseases. Here the authors show that the transcription factor RFX1 limits Th17 differentiation and is protective against the pathogenesis of Th17-driven autoimmune diseases.

Psoriasis is a common inflammatory skin disease. Infiltration of inflammatory cells and excessive proliferation of keratinocytes are the histopathological markers of psoriasis. The transcription factor Wilms Tumor 1 (WT1) is overexpressed in several tumor types, and plays an important part in the proliferation and apoptosis of cells. Studies have found that, compared with normal skin, WT1expression in the skin lesions of patients with psoriasis are increased significantly. Knockdown of WT1 inhibited the proliferation of a human epidermal keratinocyte cell line (HaCaT cells) and promoted their apoptosis, whereas WT1 overexpression exhibited the opposite effect. WT1 was overexpressed or inhibited in HaCaT cells by transfection with the WT1 plasmid or WT1 small interferring RNA (siRNA) using Lipofectamine 2000. Transcriptome sequencing and bioinformatics analysis revealed significant differences in IL-1β expression between the experimental group and control group. Real-time reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assays showed that expression of IL-1β and WT1 were consistent. Subsequently, IL-1β was demonstrated to be a target of WT1 by chromatin immunoprecipitation (ChIP)-sequencing and luciferase reporter assay. ChIP-qPCR showed that WT1 regulated IL-1β expression by altering acetylation. Expression of WT1 mRNA was positively correlated with expression of IL-1β mRNA in psoriatic skin lesions. Our study suggested that WT1 likely promotes psoriasis development by regulating its target gene IL-1β, which shows high expression in psoriatic lesions and is involved in psoriasis development. These findings provide a new target for psoriasis treatment.

Aim To compare the therapeutic effect of 1.88-mg and 3.75-mg gonadotrophin-releasing hormone agonist (GnRHa) in the treatment of stage III–IV endometriosis after laparoscopic surgery. Methods Fifty patients with stage III–IV endometriosis diagnosed on laparoscopy were randomized into two groups according to GnRHa dose. Sex hormone level, symptoms of estrogen deficiency and lumbar vertebrae bone density were compared and analyzed between the two groups. Results Bone density was decreased in both groups at 20 weeks after treatment, and the degree of bone density loss in the full-dose group (5.6%) was higher than in the half-dose group (1.2%; P 0.05) after resumption of menstruation. Both groups had symptoms of perimenopause at 8 weeks after treatment (P > 0.05), but change in Kupperman score with time differed between the groups. At 16, 20 weeks after treatment, the symptoms of perimenopause in the half-dose group were improved, and Kupperman score was lower than at 8 weeks after treatment. In the full-dose group, however, Kupperman score was higher than at 8 weeks after treatment and higher than in the half-dose group (P 0.05). Estradiol (E2) in the full-dose group was significantly lower than in the half-dose group (P

The goal of this study was to use the biomarkers human papillomavirus (HPV) L1 and p16 to develop an algorithm that could triage the individual patient with CIN1 at risk for progression. A total of 82 patients initially diagnosed with CIN1 at Peking University Shenzhen Hospital in China had their initial and follow-up paraffin-embedded tissue blocks immune-stained for HPV L1 capsid protein and p16. For CIN1, any staining of abnormal epithelium was considered positive. All patients were followed until they developed CIN2+ or for ≥3 years. About 38 patients regressed (HPV-, Cytology-), 17 persisted (CIN1), and 27 progressed (≥CIN2+). At initial diagnosis, HPV L1 capsid protein was expressed in 42.7% of the CIN1 cases. There was no difference in L1 expression among the 3 groups. However, p16-positive staining in the progression group was significantly higher than in the regression group (P

Background Cervical squamous cell carcinoma (CSCC) is the most frequent type among cervical cancers. Although the altered miRNA miR-30d expression and the amplified chromosome locus of MIR30D, 8q24, have been reported in somatic cancers, the definitive functional impact of such region especially in CSCC remains under-investigated. Methods One hundred thirty-six cases of CSCC tissues and matched adjacent normal ovarian epithelial tissues were assessed in this study. FISH and qPCR were performed to detect the copy number and microRNA expression of MIR30D gene in the collected samples. In in-vitro study, proliferation of CSCC cells were analyzed using WST-1 assay and invasion abilities of CSCC cells were evaluated by transwell assay. In-vivo study using a model of nude mice bearing tumor was also performed. Results Copy number gains of MIR30D were detected in 22.8% (31 out of 136) of CSCC samples. Copy number of MIR30D was positively correlated with tumor progression. CSCCs with lymph node metastases (LNM) also showed more frequencies (36.4%) of MIR30D amplification than those without LNM (18.4%, p

The aim of the study was to evaluate the human papillomavirus (HPV) viral load combined with cytology as a secondary screening strategy after primary HPV screening.The data referring to direct Hybrid Capture 2 (HC2), cytology, and histology from Shenzhen Cervical Cancer Screening Trial II were re-analyzed to determine the correlation between viral load and cervical lesions. In addition, algorithms using different viral loads as cut points for immediate colposcopy plus cytology triage were compared with several recommended or controversial primary screening methods.A total of 8,556 women with a mean age of 38.9 years were included in the analysis, of which 13.67% tested high-risk HPV positive with a prevalence of 2.72% for cervical intraepithelial neoplasia 2+ (CIN 2+) and 1.65% for CIN 3+. A significant correlation was observed between increasing relative light units/control (RLU/CO) values and worsening cervical lesions. The mean RLU/CO values for negative, CIN 1, CIN 2, CIN 3, and cancer were 6.86, 119.43, 410.90, 449.39, and 853.26, respectively. A larger proportion of HPV infections with relative high viral load (≥10 RLU/CO) were found in higher-grade lesions. The algorithm using 10 or greater RLU/CO as cut point for immediate colposcopy followed by triage cytology for the other positive (≥110 RLU/CO) had sensitivity of 93.13%/96.45% and specificity of 92.32%/91.44% for CIN 2+/3+, and the colposcopy referral rate was 10.00%.Human papillomavirus viral load level is positively associated with cervical lesion grade. Ten relative light units/control or greater is a viable threshold for immediate colposcopy whereas 1 or greater or less than 10 RLU/CO is advised to reflex cytology for optimizing sensitivity and specificity, as well as referral rates.

Psoriasis is a chronic, systemic, hyper-proliferative immune-mediated inflammatory skin disease. The results of epidemiological investigations have shown that psoriasis affects around 2% of the general population worldwide, and the total number of psoriasis patients is more than 6 million in China. Apart from the skin manifestations, psoriasis has been verified to associate with several metabolic comorbidities, such as insulin resistance, diabetes and obesity. However, the underlying mechanism is still not elucidated. Adipocytes, considered as the active endocrine cells, are dysfunctional in obesity which displays increased synthesis and secretion of adipokines with other modified metabolic properties. Currently, growing evidence has pointed to the central role of adipokines in adipose tissue and the immune system, providing new insights into the effect of adipokines in linking the pathophysiology of obesity and psoriasis. In this review, we summarize the current understanding of the pathological role of adipokines and the potential mechanisms whereby different adipokines link obesity and psoriasis. Furthermore, we also provide evidence which identifies a potential therapeutic target aiming at adipokines for the management of these two diseases.

Uterine fibroids are common benign tumors in the female reproductive system. A hysterectomy is the most effective treatment for symptomatic fibroids. For patients desiring pregnancy, laparoscopic intracapsular myomectomy (LM) is an alternative surgery option. Although LM is widely accepted to treat fibroids, it is technically demanding with risk of excessive bleeding and difficult suturing, especially in cases with large fibroids or tumors in unusual locations. Therefore, we developed an intracapsular rotary-cut procedure (IRCP) as a modification of laparoscopic intracapsular myomectomy, with the intention to minimize risks of LM and help uterine healing. A summary of the improvements to the IRCP is described: 1) making an incision at the site of the fibroid with a length of one-third to one-half of the fibroid's diameter at a depth reaching the fibroid's surface; 2) holding the fibroid stably and making rotary cuts on the fibroid at a depth of 0.5-1 cm within its pseudo-capsule while pulling it outward slightly, making sure not to cut off any pieces of the fibroid; and 3) repeating the cutting-and-pulling until the longest dimension of the fibroid is outside the incision. The multiple cuts are to minimize the diameter and extend the length of the fibroid. When the multiple cuts cause half of the fibroid body to "shrink", the fibroid is squeezed out by contraction of the surrounding myometrium. Evaluation of the outcomes of IRCP showed that the time of enucleation and suturing, intraoperative bleeding, and decline of hemoglobin were significantly lower in the IRCP group than the LM group. As for reproductive outcomes, the full-term live birth rate of the IRCP group was significantly higher than that of LM group. However, there was no difference in delivery modes between the two groups. In conclusion, IRCP significantly benefits fertility preservation by minimizing damage to the uterus, protecting myofibers of the pseudo-capsule, and resulting in a shallower residual cavity, which eases stitching and causes less bleeding. It is worthwhile to adopt IRCP in younger patients who desire preservation of their fertility.

A material of graphitic carbon nitride-supported cobalt oxides (Co3O4/g-CN) was synthesized via a facile and cost-effective impregnation route as a high-performance catalyst for decomposition of N2O. For comparison, bare Co3O4 and other Co3O4 catalysts supported on activated carbon (AC) and γ-Al2O3 (Co3O4-A, Co3O4/AC, and Co3O4/γ-Al2O3, respectively) were also prepared. While g-CN was found to be active in the decomposition of N2O, AC and γ-Al2O3 were inert to this reaction. Co3O4/g-CN showed superior catalytic activity than the other catalysts, and concurrently exhibited much higher specific activity compared to Co3O4-A. The experimental results revealed that all examined catalysts had the spinel structure. The Co species could incorporate into the g-CN matrix/layers and bond to the g-CN matrix through Co-N coordination bonds. The excellent performance of Co3O4/g-CN was attributed to the high surface Co2+ content, massive surface oxygen species, facile electrons transfer from the catalyst to N2O domains, and the synergistic coupling effects among active species such as Co3+/Co2+ redox couple, Co-N, and nitrogen sites. The active Co3O4/g-CN catalyst additional activity tests were conducted with N2O gas contaminated with H2O, O2, or NO.

Intravenous leiomyomatosis is a rare benign disease. We here in present the case of a 39-year-old woman with a history of hysterectomy who presented with intermittent abdominal pain, palpitations and tightness of the chest. Physical examination revealed the presence of a pelvic mass of regular shape. Gynecological ultrasonography, computed tomography scans and three-dimensional (3D) cardiac ultrasonography were used to evaluate the imaging characteristics of the mass and reach a final diagnosis. The mass appeared to extend to the iliac veins, renal veins and inferior vena cava on imaging examination. The mass was successfully excised under non-extracorporeal circulation in one stage. Pathological examination of tumor samples indicated intravenous leiomyomatosis. After the operation, the symptoms were dissipated and no abnormal echo was observed in the inferior vena cava or the right atrium on 3D-cardiac ultrasonography. The patient is currently followed up without signs of recurrence. The aim of the present study was to describe in detail the diagnostic procedure and treatment in order to improve our current understanding of this disease.

The aim of the study was to determine whether p16 positive/cervical intraepithelial neoplasia (CIN) 2, 3, and cancer (p16 + CIN 2/3+) detected by colposcopy-directed or random biopsy differ by age, referral cytology, human papillomavirus (HPV) 16, and lesion size.Data from the Shenzhen Cervical Cancer Screening Trial II where, at colposcopy, women who had directed and random cervical biopsies were reviewed to find women with CIN 2, 3, or cancer; 227 such women identified had their paraffin-embedded tissue blocks recut, reviewed, and then immune stained for p16. Data were analyzed by χ, Fisher exact test, and linear regression.After histopathologic review and p16 staining of CIN 2, 175 women were diagnosed with p16 + CIN 2/3+. When compared with those diagnosed by colposcopy-directed biopsy (n = 138), those diagnosed by random biopsy (n = 37) were more likely to have Cytology-Lo (cytology of negative, atypical squamous cells of undetermined significance, or low-grade squamous intraepithelial lesion; p = .07), less likely to have HPV 16 (p = .041), more likely to be 51 years or older (p = .022), and more likely to have 1 quadrant lesions (p.001). Logistic regression analysis showed p16 + CIN 2/3+ diagnosed by random biopsy was predicted by 1 quadrant lesions (p.0001) and age of 51 years or older (p = .03) but not by Cytology-Lo (p = .71) nor HPV 16 (p = .26).Women with p16 + CIN 2/3+ diagnosed by random biopsy are older and less likely to have HPV 16; hence, CIN diagnosed by random biopsy may not be as virulent as CIN diagnosed by colposcopy-directed biopsy. Regardless, we advise that CIN diagnosed by random biopsy be viewed like CIN diagnosed by colposcopy-directed biopsy.

Objective The aim of this study was to determine if there is a different p16 expression pattern between colposcope-directed and random (colposcope-undetectable) biopsies of cervical intraepithelial neoplasia (CIN2) and CIN3. Methods Cervical biopsies that were positive for CIN2 or CIN3 were selected from a database of samples acquired during a large population-based clinical trial in Guangdong Province in China (Shenzhen Cervical Cancer Screening Study II). Blocks were recut, reread, and then immunostained for p16. Biopsies were categorized as either colposcope-directed or random biopsies. Diffuse staining was considered p16 positive, whereas focal or no staining was considered p16 negative. Differences were determined by the Fisher exact test. Results Among the patients with CIN3, there were 232 individual biopsies of CIN3. Sixty were randomly collected, and 172 were colposcopy directed. p16 positivity for the colposcope-directed and random biopsies was 97.7% and 91.7%, respectively (p = 0.052). Like the CIN3 biopsies, colposcope-directed and random CIN2 samples expressed p16 similarly (86.8% [46/53] and 82.6% [19/23], p = .73, respectively). Conclusions Based on our data, even small colposcope-undetectable biopsies of CIN3 are significant. Random biopsies of CIN2 or CIN3 demonstrate similar p16 positivity as visible lesions and therefore might be expected to have a similar natural history.
