Exosomes: potential diagnostic markers and drug carriers for adenomyosis.

Adenomyosis is a common benign gynecological disorder and an important factor leading to infertility in fertile women. Adenomyosis can cause deep lesions and is persistent and refractory in nature due to its tumor-like biological characteristics, such as the ability to implant, adhere, and invade. The pathogenesis of adenomyosis is currently unclear. Therefore, new therapeutic approaches are urgently required. Exosomes are nanoscale vesicles secreted by cells that carry proteins, genetic materials and other biologically active components. Exosomes play an important role in maintaining tissue homeostasis and regulating immune responses and metabolism. A growing body of work has shown that exosomes and their contents are key to the development and progression of adenomyosis. This review discusses the current research progress, future prospects and challenges in this emerging therapeutic tool by providing an overview of the changes in the adenomyosis uterine microenvironment and the biogenesis and functions of exosomes, with particular emphasis on the role of exosomes and their contents in the regulation of cell migration, proliferation, fibrosis formation, neovascularization, and inflammatory responses in adenomyosis.

Comparative Efficacy and Safety of Chinese Patent Medicines for Cervical High-risk Human Papillomavirus Infection: A Bayesian Network Meta-analysis.

Background: Many Chinese patent medicines have been reported to show anti-tumor cell effects on cervical cancer. To estimate the comparative effectiveness and safety of Chinese patent medicines for cervical high-risk human papillomavirus (HR-HPV) infection. Methods: Randomized controlled trials (RCTs) of Chinese patent medicines for HR-HPV infection were searched in eight databases until 31 August 2022, and two review authors independently extracted data and assessed the risk of bias. Outcomes concerning efficacy were evaluated as odds ratio (OR) and 95% credible intervals (CrI) utilizing R 4.1.2 and Stata 16.1. The protocol was registered on the International Prospective Register of Systematic Reviews (CRD42022351120). Results: We ultimately identified 60 RCTs that involved 5,951 participants and 8 interventions. Chinese patent medicines combined with recombinant human interferon (rhIFN) have better treatment effects than rhIFN alone. The results showed that Baofukang suppository (BFK) combined with rhIFN is greater for the rate of HR-HPV clearance follow-up at 6 months (SUCRA = 78.16%). Kushen gel (KS) combined with rhIFN ranked first for the rate of HR-HPV clearance after treatment (SUCRA = 90.77%). Furthermore, KS + rhIFN is most likely to be the best intervention for improving the clinical effectiveness rate (SUCRA = 87.39%). Adverse reactions were not statistically significant in BFK + rhIFN versus BFK, BFK + rhIFN versus rhIFN, and BFK versus rhIFN. Conclusion: The combination of Chinese patent medicines with rhIFN may demonstrate a higher efficacy than rhIFN alone in clearing the virus and improving cervical symptoms. Weighing with the clinical comprehensive efficacy, BFK + rhIFN and KS + rhIFN maybe the optimal treatments for cervical HR-HPV infection. However, more high-quality randomized controlled trials are needed in the future to further confirm the efficacy and safety of proprietary Chinese medicines for cervical HR-HPV infection.

Effect of Amomum villosum essential oil as an additive on the chemical composition, fermentation quality, and bacterial community of paper mulberry silage.

Paper mulberry (Broussonetia papyrifera L., PM) is being used as a new type of animal protein feed to address the feed crisis. To investigate the effect of additives on the chemical composition, fermentation quality, and bacterial community of PM silage (at room temperature, 25°), paper mulberry was fermented with formic acid (FA), Amomum villosum essential oil (AVEO) and lactic acid bacteria (LAB) inoculant treatments. The results showed that fresh PM had a low water-soluble carbohydrate (WSC) content and large amounts of unclassified bacteria. Compared with the CK and LAB treatments, the FA and AVEO treatments significantly (P < 0.05) decreased the pH and increased the lactic acid content of PM silage after 60 days of ensiling. In the AVEO-treated silages the abundance of Lactococcus in the early stage of ensiling increased by 14.09%, the abundances of Levilactobacillus and Lentilactobacillus in the late stage of ensiling increased by 58.34 and 91.12%, respectively, and the abundance of Stenotrophomonas decreased by 94.71%, resulting in improved PM silage quality. These results confirmed that AVEO could potentially be developed as a new additive for improving the fermentation quality of silage.
