The aim of this paper was to find out the active components of Epimedium brevicornum using network pharmacology, and find the potential targets and mechanisms. The TCMSP database was used to screen the active ingredients, and TTD and DrugBank databases were used to predict the potential targets with the literature mining. The pathway annotation was used to enrich and analyze the active ingredients and potential targets of E. brevicornum. The results showed that E. brevicornum had34 potential target active ingredients, including 21 flavones components, such as icariin, epimedin A, epimedin B, epimedin C, Yinyanghuo A, Yinyanghuo C and so on, 2 lignans involved in (+)-cycloolivil and olivil, 3 sterols consisting of sitosterol, 24-epicampesterol and poriferast-5-en-3beta-ol. The main predicted targets included Ptgs2, NCOA6, RANK, OPG, WNT9B, PTH1R, BMPs, SMAD4A and so on. There were 88 signaling pathways involved in 10 signaling pathways which was related to inflammation, such as NF-kappa B signaling pathway, T cell receptor signaling pathway, IL-17 signaling pathway and 10 pathways which was related to cancer included breast cancer, bladder cancer, pancreatic cancer and so on, and estrogen related signaling pathways included estrogen signaling pathway. This laid the foundation for the discovery of the active components of Epimedium and the study on its mechanism of action.

Estrogen is a steroid hormone produced mainly by the ovaries. It combines with the nuclear receptors to exert the biological effects influencing the metabolism of body. Elevated levels of estrogen are often associated with altered iron levels in mammals. Furthermore, the findings of estrogen response element (ERE) have demonstrated that estrogen affects iron metabolism directly in peripheral tissues. In this review, we will briefly summarize the effect of estrogen on iron metabolism in mammals, and discuss recent progress in the mechanisms of estrogen on some iron related proteins in order to provide guidance for clinical use of estrogen. Estrogen and iron metabolism are closely related, but the exact regulatory mechanisms still need further exploration.

Estrogen impacts neural development; meanwhile, it has a protective effect on the brain. Bisphenols, primarily bisphenol A (BPA), can exert estrogen-like or estrogen-interfering effects by binding with estrogen receptors. Extensive studies have suggested that neurobehavioral problems, such as anxiety and depression, can be caused by exposure to BPA during neural development. Increasing attention has been paid to the effects on learning and memory of BPA exposure at different developmental stages and in adulthood. Further research is required to elucidate whether BPA increases the risk of neurodegenerative diseases and the underlying mechanisms, as well as to assess whether BPA analogs, such as bisphenol S and bisphenol F, influence the nervous system.

The incidence of systemic lupus erythematosus (SLE) is known to be affected by sex hormone. Patients with Klinefelter's syndrome were reported to have abnormal sex hormonal metabolism and their chronic estrogenic stimulation seems to affect the pathogenesis of SLE. Therefore, association of SLE and Klinefelter's syndrome has been considered as a clue of the effect of sex hormone on SLE. We report the first case of Klinefelter's syndrome in a patient with SLE in Korea and discuss the association of SLE with Klinefelter's syndrome.
