Effect of Renal Sympathetic Denervation on Ventricular Electrical Activity in Myocardial Infarction.
Coronary artery blockage causes myocardial infarction (MI), a frequent and serious cardiovascular disease. The early recurrence of post-MI ventricular fibrillation after defibrillation has been widely investigated and treated. This research investigated the relationship between electrophysiological indicators of early recurrence following defibrillation in post-MI ventricular fibrillation and sympathetic renal denervation's therapeutic benefits and probable causes. ⋯ Electrophysiological indications of early recurrence following defibrillation in post-MI ventricular fibrillation are linked to sympathetic renal denervation's therapeutic benefits. Myocardial damage and fibrosis may be reduced, ECG features improved, and the early recurrence rate reduced by sympathetic renal denervation. One possible method of sympathetic renal denervation intervention is reduced sympathetic nerve activity.

Shenqi Qiangjing Granules Ameliorate Asthenozoospermia in Mice by Regulating Ferroptosis through the METTL3/GPX4 Signaling Axis.
Asthenozoospermia is a leading cause of male infertility, yet current pharmacotherapies yield suboptimal outcomes, underscoring the urgent need for novel treatment modalities. Herein, we induced asthenozoospermic mouse models using busulfan and investigated the therapeutic effects of Shenqi Qiangjing Granules (SQ) on testicular pathology, serum sex hormone and steroidogenic enzyme levels, and ferroptosis. Furthermore, utilizing GC-1 spg cell lines, we elucidated the role of the METTL3-mediated m6A modification in GPX4 mRNA stability. ⋯ Knockdown of METTL3 mimicked the effects of SQ treatment, while overexpression of METTL3 partially reversed SQ-mediated effects on ferroptosis and asthenozoospermia, underscoring the pivotal role of METTL3 in SQ therapy. In conclusion, the METTL3-GPX4-ferroptosis axis emerges as a novel regulatory pathway in the pathogenesis of asthenozoospermia. Targeting this axis, particularly through interventions such as SQ treatment, holds promise for the management of male infertility.

Four Genes with Seven Targeted Drugs might be Treatment for Diabetic Nephropathy and Acute Coronary Syndrome.
Diabetes nephropathy (DN) is a main risk factor for acute coronary syndrome (ACS), but the molecular mechanism is unknown. This research used bioinformatics approaches to uncover potential molecular mechanisms and drugs for DN and ACS. GSE142153 and GSE19339 were downloaded from the Gene Expression Omnibus (GEO) database. ⋯ Hub gene and transcription factor interactions were constructed. Seven drugs targeted at VEGFA, IL6, IL1B, and IL1A were evaluated. Four genes and seven drugs were evaluated that could provide a novel perspective for DN and ACS in the future.
