Introduction: The aim of this study was to analyze the correlation between abnormal vaginal microflora and different types of human papillomavirus (HPV) infection and cervical precancerous lesions during the perimenopausal period.
Methodology: This retrospective study included women patients who underwent liquid-based cytologic test (LBC), HPV test, leucorrhea routine test, or routine urine test at the China-Japan Friendship Hospital between October 2019 and January 2020. A cut-off of 45 years was used as the cut-off age for menopause. The positivity and subtypes of HPV were determined using a chip-based assay. Vaginal microflora was determined using an HB-2012a flow-through hybridization instrument.
Results: A total of 132 patients were included in this study. 97 patients were younger than 45 years of age, with a median age of 35 (8.0), and 35 patients ≥ 45 years of age, with a median age of 55 (11.0). There were no significant differences in cytology, type of cervical lesion, HPV type, and common pathogens of the reproductive tract (all p > 0.05). The multivariable analysis showed that only HPV-16 infection lesions (OR: 2.825, 95% CI: 1.121-7.120, p = 0.028), Chlamydia trachomatis infection (OR: 0.142, 95% CI: 0.024-0.855, p =0.033), and Mycoplasma infection (OR: 7.750, 95% CI: 1.603-37.474, p = 0.011) were independent risk factors for cervical precancerous lesions. The menopausal status (with age < 45 or > 45 years as its surrogate) was not associated with cervical precancerous lesions.
Conclusions: Menopause was not associated with cervical precancerous lesions. The results suggest that the prevention and treatment of HPV-16, Chlamydia trachomatis infection, and Mycoplasma infection could be significant to prevent the occurrence of cervical precancerous lesions.

5-Methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) are crucial epigenetic modifications in eukaryotic genomic DNA that regulate gene expression and are associated with the occurrence of various cancers. Here, we combined bisulfite conversion with 4-acetamido-2,2,6,6-tetramethyl-1-oxopiperridinium tetrafluoroborate (ACTBF, TCI) oxidation to develop a label-free and sequence-independent isothermal amplification (BTIA) assay for a genome-wide 5mC and 5hmC analysis. The BTIA strategy can distinguish 5mC and 5hmC signatures from other bases with high sensitivity and good specificity, avoiding sophisticated chemical modifications and expensive protein labeling.

This study explores the effects of plant compounds on human papillomavirus (HPV)-induced W12 cervical precancer cells and bioelectric signaling. The aim is to identify effective phytochemicals, both individually and in combination, that can prevent and treat HPV infection and HPV associated cervical cancer. Phytochemicals were tested using growth inhibition, combination, gene expression, RT PCR, and molecular docking assays.

Cervical cancer, while preventable through screening and treatment of cervical precancer, remains a global challenge with a disproportionately high burden of disease in resource-limited settings, especially in low- and middle-income countries (LMICs). Lack of affordable, easy-to-use screening and diagnostic tests contributes to this disparity. Most commercially available tests are not appropriate for use in LMICs due to resource constraints.

Cervical cancer is one of the most prevalent cancers among women, posing a significant threat to their health. Early screening can detect cervical precancerous lesions in a timely manner, thereby enabling the prevention or treatment of the disease. The use of pathological image analysis technology to automatically interpret cells in pathological slices is a hot topic in digital medicine research, as it can reduce the substantial effort required from pathologists to identify cells and can improve diagnostic efficiency and accuracy.
