Effectiveness and safety of REBACIN as a non-invasive intervention for persistent high-risk human papillomavirus infection: A real-world prospective multicenter cohort study.

Background: We previously reported that REBACIN effectively eliminates persistent high-risk human papillomavirus (hrHPV) infection. Here, we conducted a prospective multicenter cohort study to evaluate the safety and effectiveness of REBACIN, taking into account factors such as specific hrHPV subtype and patient's age.

Methods: According to inclusion/exclusion criteria and participant willingness, 3252 patients were divided into REBACIN group while 249 patients into control group.

Ovariectomy with simulated vaginal delivery to establish a rat model for pelvic organ prolapse.

The widespread prevalence of Pelvic Organ Prolapse (POP) and the paucity of ongoing treatments prompted us to develop a unique rat model combining ovariectomy and simulated vaginal delivery. We hypothesized that the tissue changes caused by low hormone levels and mechanical stretch could complement each other. Thus, the combined model can potentially mimic the collagen metabolism of vaginal wall tissue as well as mechanical stretch properties to complement disease progression in POP.

Modern Medicine: Ideas and Advances.

Considering the limitations of medical science and the risks associated with medical treatments, we need to re-examine the connotation of medical science from the perspective of philosophy. Medical science is the natural expression of human kindness and human nature of rescuing the dying and healing the wounded. It is a combination of the natural sciences, social sciences, and humanities.

This study aimed to explore TME- related genes of prognostic value in patients with endometrial cancer (EC) and establish a prediction model for EC. The RNA-Seq data and clinicopathological characteristics of 521 subjects were obtained from The Cancer Genome Atlas (TCGA) database.

ES Sampler, a minimally invasive endometrial sampling tool that obtains specimens suitable for both cytological and histological analysis.

Aim: Conventional endometrial examination by dilatation and curettage (D&C) is not accepted by many patients because it is associated with pain and risk of injury and typically requires anesthesia and hospitalization. While several less invasive endometrial screening tools have been developed, their diagnostic value is generally inferior to D&C. Therefore, the purpose of this study was to evaluate the effectiveness of a new, minimally invasive device, called the ES Sampler, for outpatient endometrial screening.

Correlation between the diversity of vaginal microbiota and the risk of high-risk human papillomavirus infection.

Objectives: Since other genital infections enhance HIV susceptibility by inducing inflammation and evidence suggests that the vaginal microbiome plays a functional role in the persistence or regression of high-risk human papillomavirus (HPV) infections, we investigated the relationship between the composition of the vaginal microbiota and the risk of high-risk HPV infection.

Methods: The study included 151 healthy women (65 HPV-positive and 86 HPV-negative) aged 20-65 at enrollment. Total genome DNA from samples was extracted using the hexadecyltrimethylammonium bromide (CTAB) CTAB method.
