Abstract (original English)

Objective To explore the medication patterns and mechanisms of action of Shaofu Zhuyu decoction (, SFZYD) in inhibiting ferroptosis through the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase 1 (HO-1)/glutathione peroxidase 4 (GPX4) pathway to improve diabetes mellitus-induced erectile dysfunction (DMED). Methods Firstly, data mining was employed to identify the medication patterns of Traditional Chinese Medicine (TCM) in treating DMED. Secondly, network pharmacology combined with a ferroptosis database was used to predict the targets. Subsequently, cell counting kit-8, 4',6-diamidino-2-phenylindole staining, reverse transcription-polymerase chain reaction (RT-PCR), and reagent kits were utilized to assess the repair effects of SFZYD on corpus cavernosum endothelial cells (CCECs) induced by high glucose (HG). Metabolic indicators, hematoxylin-eosin staining, and Masson staining were performed to observe the restorative effects of SFZYD on erectile function and penile tissue in diabetic rats. Finally, using Nrf2 inhibitors, the expression of related proteins and mRNAs was detected through Western blotting and RT-PCR. Reactive oxygen species levels and mitochondrial membrane potential were detected by flow cytometry. Results Data mining revealed that the prescription rules for blood stasis-type DMED coincide with the treatment principles of SFZYD. Network pharma
