Encapsulating peritoneal sclerosis（EPS）is a rare and serious complication in patients with long-term peritoneal dialysis and a history of recurrent and severe peritoneal dialysis-associated peritonitis（PDAP）. Early diagnosis of EPS is difficult，clinical prognosis is poor，and the fatality rate is high. The pathogenesis of EPS is still not fully understood，and ideal prevention and treatment regimens are still lacking. Tamoxifen，a selective estrogen receptor modulator，is currently used in the treatment of breast cancer，ovarian cancer and some diseases characterized by fibrotic lesions. Studies have shown that tamoxifen can also be used to treat EPS. In this article，research progress in EPS and tamoxifen in the treatment of EPS was systematically reviewed.

Recently, research on the circadian rhythm of hypertension has gained popularity. However, few bibliometric analyses have been conducted in this field. In this study, CiteSpace 6.1. R6, VOSviewer 1.6.18, R language (version 4.2.3), R package Bibliometrix (4.1.2), and Microsoft Excel 365 were used to conduct the data mining and knowledge visualization analysis. A total of 1,560 papers from 1,825 institutions in 77 countries were included. Research on the role of circadian rhythms in hypertension is increasing annually. Overall, Chronobiology International published the most literature and Hypertension received the most citations. Ramon Hermida from the Universidade de Vigo in Spain published the most papers and had the most citations. The United States of America and Japan have been the most productive countries. The University of Ferrara, Universidade de Vigo, and the University of California system produced the most publications. Amongst authors, Hermida had the most and longest literature bursts. Keywords such as “chronic kidney disease,” “oxidative stress,” and “gene expression” have been breakout keywords since 2014. This study revealed the dynamic evolution of research on circadian rhythms in hypertension and provides a knowledge base for researchers. [ABSTRACT FROM AUTHOR]
