Objective: To evaluate the clinical value of different combination strategies of high-risk HPV (hr-HPV) testing and Thinprep cytology test (TCT), a cervical cytology test, for cervical cancer screening, especially for high or higher-grade squamous intraepithelial lesion (HSIL) in Shuangliu District, Chengdu City.
Methods: The study is a population-based randomized clinical trial. Women aged 35 to 65 years meeting the inclusion criteria were enrolled for the study.
To evaluate the potential role of interleukin-31 and interleukin-33 in diagnosis and prognosis from endometrial cancer. Tissue samples and clinical data were collected from 260 patients with endometrial cancer and 150 control patients with benign uterine diseases. Immunohistochemistry and ELISA testing quantified the expressions of interleukin-31 and interleukin-33 and their receptors.

The aim is to evaluate the performance of p16/Ki-67 and p16/MCM2 staining to triage high-risk human papillomavirus- (hrHPV-) positive women. Cervical specimens were collected from eligible women and tested for hrHPV genotyping, cytology, p16/Ki-67, and p16/MCM2 staining at baseline.

The expressions of Pten and CD4FOXP3 T cells were quantified by immunohistochemistry and immunofluorescence.

Women with HR-HPV infection or cytological abnormalities (≥ASC-US) were referred for colposcopy and biopsy.

Materials And Methods: RNA sequencing (RNA-seq) and alignments were performed to identify lncRNAs and mRNAs using endometrial samples collected from 3 patients and 3 control women. A subset of 10 differentially expressed lncRNAs and 6 mRNAs were validated in all participants using quantitative reverse transcription polymerase chain reaction.
Most human papillomavirus (HPV) infections are transient and additional triage approaches should be built after HPV-based primary cervical cancer screening. We evaluated the accuracy of p16/Ki-67 and p16/mcm2 dual staining as biomarkers for triaging HPV positive women in China. 4070 participants aged 35 to 64 years attending ongoing cervical cancer screening were enrolled in 2015-2016.

Our study aimed to evaluate the stability of cervical specimens collected with dry swabs and stored dry, compared to liquid-based cytology (LBC) samples, as detected by HPV DNA testing. Women with abnormal cytological findings or HPV-positive results at colposcopy were recruited from the West China Second University Hospital, Sichuan University, between October 2013 and March 2014.

Materials And Methods: Using biopsies collected as part of a screening study conducted in rural China, we randomly selected 50 biopsies with a precancerous diagnosis of cervical intraepithelial neoplasia grade 2 (CIN2) or more severe (CIN2+) and 50 biopsies with diagnosis of CIN less severe than CIN2, and stained them for p16 using a commercial IHC kit. Twelve nonpathologists of varying educational backgrounds living in Beijing, China received video training and were assigned one of 4 sets of 25 CIN2+ and 25 CIN less severe than CIN2 for evaluation.
p16(INK4A) is strongly expressed in tissues diagnosed as cervical intraepithelial neoplasia (CIN) and cancer in women infected with human papillomavirus (HPV), but few prospective studies have evaluated p16(INK4A) as a marker for the risk of low-grade CIN (CIN1) progression. We investigated the prevalence of p16(INK4A) immunostaining by CIN grade and whether overexpression of p16(INK4A) in CIN1 predicts future risk for high-grade CIN in Chinese women. 6,557 Chinese women aged 30-49 years were screened from 2003 to 2005 using cytology and carcinogenic HPV test.

Objective: To evaluate the clinical application value of flexible multi-analyte profiling (xMAP) technology in detecting high-risk human papillomavirus (HR-HPV).
Methods: Totally 1 061 women, aged 21-65 years, were randomly enrolled into the study. Cervical exfoliated cells were used in xMAP technology and hybrid capture II (hc2).
