Research status of polycystic ovary syndrome treatment: a mini review and a bibliometric analysis from 2010 to 2023.

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in premenopausal women, often linked to abdominal obesity, insulin resistance, and metabolic issues. With its heterogeneous nature, PCOS treatment should be tailored to individual symptoms and patient preferences. This study examines collaboration networks among countries, institutions, authors, references, and journals related to PCOS treatment. METHODS: Web of Science data was analyzed using VOSviewer and CiteSpace for bibliometric visualization. Chinese and Western medicine treatments for PCOS were reviewed, emphasizing symptom-targeted solutions. RESULTS: Data from 4682 records authored by 400 individuals from 515 institutes in 62 countries revealed China as the leading contributor. Notable authors include Monash University and Richard S. Legro. Common research themes include adipocytes, inflammation, insulin sensitivity, oxidative stress, and the gut microbiome. Tailoring treatment to individual needs is essential, focusing on hyperandrogenism, ovulation, and insulin resistance, with lifestyle counseling to address obesity. CONCLUSION: This bibliometric analysis provides valuable insights into the research status of PCOS treatment. China has made significant contributions, and complementary and alternative therapies, such as traditional Chinese medicine and acupuncture, have also shown beneficial effects recently. The research on inflammation, oxidative stress, and the gut microbiome may provide new targets and strategies for the treatment of PCOS. The recognition of the metabolic problems in PCOS patients facilitates the formulation of more personalized treatment plans to improve the prognosis of patients.

Mechanisms of Bushen Tiaoxue Granules against controlled ovarian hyperstimulation-induced abnormal morphology of endometrium based on network pharmacology.

Bushen Tiaoxue Granules (BTG) is an empirical Chinese herbal formula that has been used for the treatment of subfertility. The protective effect of BTG on controlled ovarian hyperstimulation (COH)-induced impaired endometrial receptivity has been reported in our previous study. This study aims to explore the mechanisms of BTG on ameliorating abnormal morphology of endometrium based on network pharmacology. Active compounds of BTG were identified via the traditional Chinese medicine systems pharmacology and UPLC-MS technology. The SwissTargetPrediction platform and HERB database were used to screen out the putative targets of BTG. Potential targets of endometrial dysfunction caused by COH were obtained from three GEO databases. Through the STRING database, the protein-protein interaction was carried out according to the cross-common targets of diseases and drugs. GO terms and KEGG pathways enrichment analyses were conducted via the Metascape database. AutoDock Vina was used for docking validation of the affinity between active compounds and potential targets. Finally, in vivo experiments were used to verify the potential mechanisms derived from network pharmacology study. A total of 141 effective ingredients were obtained from TCMSP and nine of which were verified in UPLC-MS. Six genes were selected through the intersection of 534 disease related genes and 165 drug potential targets. Enrichment analyses showed that BTG might reverse endometrial dysfunction by regulating adherens junction and arachidonic acid metabolism. Hematoxylin-eosin staining revealed that BTG ameliorated the loose and edematous status of endometrial epithelium caused by COH. The protein expression of FOXO1A, ß-Catenin and COX-2 was decreased in the COH group, and was up-regulated by BTG. BTG significantly alleviates the edema of endometrial epithelium caused by COH. The mechanisms may be related to adheren junctions and activation of arachidonic acid metabolism. The potential active compounds quercetin, taxifolin, kaempferol, eriodictyol, and isorhamnetin identified from the BTG exhibit marginal cytotoxicity. Both high and low concentrations of kaempferol, eriodictyol, and taxifolin are capable of effectively ameliorating impaired hESC cellular activity.

Burden and attributable risk factors of ischemic stroke in China from 1990 to 2019: an analysis from the Global Burden of Disease Study 2019.

Background: The epidemiologic characteristics and attributable risk factors of ischemic stroke in China have changed over the past three decades. An up-to-date analysis on deaths, disability-adjusted life-years (DALYs), prevalence, incidence, and attributable risk factors of ischemic stroke for China is needed. This study aims to provide a comprehensive analysis of burden and attributable risk factors of ischemic stroke at national level in China by sex from 1990 to 2019. Methods: This is a secondary analysis of the Global Burden of Disease (GBD) study 2019. All data used in this study was derived from the 2019 GBD study. Deaths, DALYs, prevalence, incidence, and attributable risk factors of ischemic stroke in China by sex from 1990 to 2019 were analyzed. Results: From 1990 to 2019, the age-standardized deaths rate decreased by 3.3%, age-standardized DALYs rate decreased by 4%, age-standardized prevalence rate increased by 33.5%, and age-standardized incidence rate of ischemic stroke in China increased by 34.7%. In 2019, ambient particulate matter pollution became an important risk factor, whereas household air pollution from solid fuels was no longer a major risk factor for ischemic stroke in China. Burden of ischemic stroke was higher in China compared to other regions. Ambient particulate matter pollution among men, and diet high in sodium, smoking, household air pollution from solid fuels among women account for the increased deaths/DALYs due to ischemic stroke in China. Conclusion: Our study revealed that great changes have occurred in burden and attributable risk factors of ischemic stroke in China in the past three decades. Distinct sex-specific differences are observed in burden and attributable risk factors.
