Postoperative depression significantly affects the quality of life of breast cancer patients. This study explores the potential therapeutic effects of esketamine on postoperative depression through modulation of the TREK-1 two-pore domain potassium channel. We analyzed data from 54 female breast cancer patients who underwent surgery at our hospital between 2019 and 2023, dividing them into experimental and control groups based on esketamine treatment. Transcriptomic sequencing of hippocampal neurons from rats identified potassium ion-related pathways and key regulatory genes, including TREK-1, influenced by esketamine. In vitro studies showed that esketamine primarily alleviates depressive symptoms by inhibiting TREK-1 protein expression, enhancing GABA neurotransmitter release, and improving neuronal activity, while overexpression of TREK-1 reversed these effects. Esketamine's inhibition of TREK-1 channels and promotion of hippocampal neuron activity effectively alleviate postoperative depression in breast cancer patients, suggesting a novel therapeutic strategy.

Unlabelled: In India, 7-8% of the population is affected by post lingual deafness, which can lead to job dissatisfaction, depression, social withdrawal, and educational challenges. Despite the benefits, cochlear implantation in Northern India remains underutilized. This study examines the impact of cochlear implants on post lingual deafness, along with their etiology and indications.

Postoperative patients receiving opioids are at risk for morbidity and mortality caused by opioid-induced respiratory depression (OIRD). Guidelines advocate electronic monitoring for OIRD during postoperative hospitalization, but the utility of home monitoring following ambulatory surgery has not been assessed. We describe the utilization of capnography and pulse oximetry in an ambulatory orthopedic cohort to determine subject/home caregiver acceptance and utility of continuous monitors at home.

Background: Digital education for outpatient patients with atrial fibrillation (AF) has gradually increased. However, research on digital education for patients undergoing atrial fibrillation catheter ablation (AFCA) is limited.
Objective: This study aimed to develop a novel digital animation-based multistage education system and evaluate its quality-of-life benefits for patients with AFCA.
Objective: To investigate the clinical efficacy of a method that corrects tear trough deformity by subcutaneous fixation of orbital septal fat flaps using syringe-guided absorbable barbed sutures.
Methods: A retrospective analysis was conducted on the clinical data of 125 cases with lower eyelid bags accompanied by tear trough deformity who were treated in the Department of Plastic Surgery at Zhengzhou People's Hospital from 2020 to 2024. Among them, there were 13 males and 112 females, with an average age of 34.
