RESUMEN
INTRODUCTION AND HYPOTHESIS: The study was aimed at systematically analyzing the research status and trends of pelvic organ prolapse (POP) using bibliometrics. METHODS: We retrieved documents published between 1975 and 2022 from the Web of Science Core Collection (WoSCC) database, and manually selected them for bibliometric analyses of country, institution, journal, highly locally cited documents and research trends based on co-citation clustering and keywords using the R Bibliometricx package and CiteSpace software. RESULTS: A total of 5,703 publications were included. Although the number of annual publications on POP increased, the trend of annual publication reached an obvious plateau in the first half of the 2010s. The USA, China, the UK, the University of Michigan, the University of Pittsburgh, and the University of Sydney were the top three countries and institutions with the most publications respectively. International Urogynecology Journal, American Journal of Obstetrics and Gynecology, and Obstetrics and Gynecology were the journals with the most extensive academic influence on the field of POP research. The international cooperation was lacking and the highly cited documents focused on high-level, evidence-based studies. Epidemiological studies and surgical treatment have achieved a plateau or decline. Recent studies have focused on conservative treatment, physical therapy, and minimally invasive surgery. In addition to evidence-based medicine studies, tissue engineering is the future direction of POP. CONCLUSIONS: This study used bibliometric analyses to provide insights into the status and potential research directions of POP. More high-quality, evidence-based medicine studies and in-depth tissue engineering research should be propelled forward.

BACKGROUND: Anti-angiogenic therapy has become one of the effective treatment methods for tumors. Long noncoding RNAs (lncRNAs) are emerging as important regulators of tumorigenesis and angiogenesis in EC. However, the underlying mechanisms of lncRNA TRPM2-AS in EC are still not clear. METHODS: We screened the differently expressed lncRNAs that were highly associated with poor prognosis and angiogenesis of EC by bioinformatics analysis, and constructed a ceRNA network based on the prognostic lncRNAs. The subcellular localization of TRPM2-AS was determined by fluorescence in situ hybridization (FISH) and nuclear cytoplasmic fractionation assay. CCK-8, EdU, transwell, western blot, qRT-PCR and endothelial tube formation assay were used to evaluate the effects of TRPM2-AS on the proliferation, invasion, migration of EC cells and angiogenesis. The targeted microRNA (miRNA) of TRPM2-AS was predicted by bioinformatic methods. The interaction between TRPM2-AS and miR497-5p, miR497-5p and SPP1 were analyzed by RNA immunoprecipitation and dual-luciferase reporter assay. A subcutaneous tumor model was used to explore TRPM2-AS's function in vivo. CIBERSORT was used to analyze the correlation between TRPM2-AS and immune cell immersion in EC. RESULTS: We found that the expression of TRPM2-AS and SPP1 was aberrantly upregulated, while miR-497-5p expression was significantly downregulated in EC tissues and cells. TRPM2-AS was closely correlated with the angiogenesis and poor prognosis in EC patients. Mechanistically, TRPM2-AS could sponge miR-497-5p to release SPP1, thus promoting the proliferation, invasion and migration of EC cells and angiogenesis of HUVECs. Knockdown of TRPM2-AS in xenograft mouse model inhibited tumor proliferation and angiogenesis in vivo. In addition, TRPM2-AS plays a vital role in regulating the tumor immune microenvironment of EC, overexpression of TRPM2-AS in EC cells stimulated the polarization of M2 macrophages and angiogenesis through secreting SPP1 enriched exosomes. CONCLUSION: The depletion of TRPM2-AS inhibits the oncogenicity of EC by targeting the miR-497-5p/SPP1 axis. This study offers a better understanding of TRPM2-AS's role in regulating angiogenesis and provides a novel target for EC treatment.

While the link between female reproductive function and cardiovascular health (CVH) is well-established, the association between pelvic inflammatory disease (PID) and CVH remains largely unexplored. This study, therefore, sets out to fill this gap in knowledge by investigating the potential relationship between PID and CVH. To ensure the reliability and validity of our findings, data for this cross-sectional study were meticulously collected from the 2015-2018 National Health and Nutrition Examination Survey (NHANES). After applying stringent exclusion criteria, a total of 2442 women were included in the study. The Life Essential 8 (LE8) scoring system, a robust tool developed by the American Heart Association (AHA), was employed to assess the CVH. Logistic regression with multiple variables and smooth curve fitting were utilized to analyze the association. Subgroup and interaction analyses were performed to determine the strength of this association across different demographic groups. The study included 2442 women, with an average CVH score of 66.29â ±â 16.27. After accounting for all covariates, each unit increase in CVH score was associated with 2% lower odds of PID prevalence (ORâ =â 0.98, 95% CI: 0.97-0.99). Notably, participants with high CVH had a striking 71% lower odds of PID prevalence compared to those with low CVH. Stratified analyses further revealed a consistent inverse association between CVH score and PID across various subgroups, underscoring the robustness of our findings. The research has uncovered a significant inverse association between CVH and PID. This suggests that improving the CVH level could be a promising strategy for reducing the odds of PID.

BACKGROUND/AIM: Chronic pelvic pain (CPP) is a common gynecological condition in women with multifactorial etiology. Some studies have revealed that patients with CPP have the same structural and functional changes in the pain matrix in the brain to patients with other types of chronic pain. However, the relationship between localized pelvic pain and changes in the structure and function of the central nervous system is still unclear. MATERIALS AND METHODS: In this study, a rat model of CPP was established by pelvic nerve ligation and behavioral tests were used to validate the model. Afterwards, we compared the expression of CCL2 in CPP and control rats and observed the changes in their behavioral patterns by blocking the expression of CCL2 in the former group. In addition, we upregulated the expression of CCL2 in human microglia cells (HMC3) to further observe the effect of CCL2 on the Notch2 pathway. RESULTS: Our results showed that the expression of chemokine ligand 2 (CCL2) in the serum exosomes, pelvic vascular endothelial cells, and cerebrospinal fluid was higher in the CPP group than the control group (p<0.05). In HMC3 treated with recombinant CCL2 protein, a significant increase in the mRNA and protein expression of Notch2 was observed. CONCLUSION: CCL2 can activate the Notch2 signaling pathway and plays an important role in the central sensitization of chronic pelvic pain.

DNA Methyltransferase 1 (DNMT1) serves as a crucial biomarker associated with various diseases and is essential for evaluating DNA methylation levels, diagnosing diseases, and evaluating prognosis. As a result, a convenient, quantitative, and sensitive assay for detecting DNMT1 is in high demand. However, current techniques for DNMT1 detection struggle to balance accuracy, low cost, and high sensitivity, limiting their clinical usefulness. To address this challenge, we have developed a DNMT1 detection method (CAED), which combines aptamer-specific recognition with a highly programmable Entropy-driven catalysis DNA network and is further integrated with the CRISPR-Cas12a system. This innovative approach achieves a detection limit as low as 90.9 fmol/L. To demonstrate the clinical applicability and significance of our CAED method, we successfully measured DNMT1 levels in 10 plasma samples 10 cervical tissue samples. These results underscore the potential of our method as an accurate, affordable, and ultra-sensitive tool for evaluating DNMT1 levels. This innovative method offers a potent means for assessing DNMT1 levels and significantly advances disease diagnosis and health risk prediction. Plus, it establishes an innovative design framework for CRISPR-Cas12a-based biosensors, tailored explicitly for enzyme content quantification.
