Globally, over 300 million surgeries are performed each year, and more than 50% of surgeries involve patients aged 65 and older. Aging poses significant challenges to perioperative brain health, as the deterioration of brain structure and function increases susceptibility to postoperative neurological complications. Protecting perioperative brain health remains a worldwide clinical challenge. With senescence, the brain undergoes a progressive decline in homeostasis across various molecular, cellular, and regional functions. Anesthetics and surgical stimuli may accelerate the disruption of brain homeostasis and exacerbate age-related neurodegeneration. This review provides a framework for understanding how anesthesia and surgery can affect brain health in the aging population and contribute to postoperative neurological complications, with a particular focus on perioperative neurocognitive disorder.

Studies on specific transient receptor potential melastatin 2 (TRPM2) channel inhibitors can deepen our understanding of the pathological mechanism of related diseases, and allow discovery of novel, effective targets and drugs for therapy. The development of TRPM2 channel inhibitors can be broadly classified into four categories with distinct characteristics: reutilization and structural modification of homologous ion channel modulators to produce a diverse array of TRPM2 channel inhibitors with strong inhibitory effects; TRPM2 channel inhibitors based on channel gating mechanism with high specificity; inhibitors identified through high-throughput screening with novel chemical structures; inhibitors developed from natural antioxidants with higher safety. In recent years, the application of computer-aided drug design has significantly accelerated the development of TRPM2 channel inhibitors. Several promising compounds such as ZA18, A1 and D9 have been discovered, and it is expected that more potent and selective TRPM2 channel inhibitor scaffolds will be discovered in the future. This article reviews the advances on the studies of TRPM2 channel inhibitors, aiming to provide insights for further research and clinical application of TRPM2 channel inhibitors.

An improved U-Net model(channel attention module U-Net,CAMU-Net)is proposed to achieve precise segmentation of retinal vessels.CAMU-Net model enhances its understanding of regional features by employing residual enhancement convolution to extract important information from the regions,improves the global feature acquisition capability by introducing feature refinement module to promote feature extraction,realizes precise segmentation by adding channel attention module to capture image features accurately,and enhances its capability to perceive target boundaries and details through a multi-scale feature fusion structure.The ablation study on the DRIVE dataset validates the role of each module in retinal vessel segmentation.The comparison with other mainstream network models on DRIVE and STARE datasets verify that CAMU-Net model is superior to other models.

Objective This study aimed to investigate the factors influencing the personal burden rate incerebral ische-mic patients,compare the difference in the burden rate among the patients with varying degrees of cerebral ischemia,provide a reference for establishing a personal burden rate evaluation,and propose suggestions for control its increase.Methods The medi-cal insurance data were collected from 8164 discharged patients in a tertiary hospital in Tianjin between January and December 2022.With the data,the Generalized Linear Model was utilized to analyze the factors affecting the personal burden rate across different Diagnosis Related Groups(DRGs).Results Statistically significant differences were observed in the cost structure a-mong different DRGs.Age,length of hospital stays,total hospitalization cost,hospital admission mode,number of hospitaliza-tions,and type of medical insurance significantly impacted the personal burden rate.The personal burden rate was inversely cor-related with age and length of hospital stays,but directly correlated with the total hospitalization cost.The patients admitted from emergency,first-time hospitalization,and those covered by the basic medical insurance program for urban employees had a lower personal burden rate.Conclusion Hospitals should establish diverse personal burden rate performance evaluation standards for patients with different types of medical insurance,incorporating factors such as average length of hospital stays and average hospi-talization cost.A more equitable hospital internal assessment plan should be developed by considering patients admitted to differ-ent departments and aligning with the characteristics of clinical pathways.Medical institutions should minimize self-funded pro-jects under declared medical insurance,increase the enrollment of cases in DRGs,and promote tiered diagnosis and treatment to reduce the personal burden rate for patients.
