Parkinson disease(PD)is one of the most prevalent neurodegenerative disorders,typically affecting the elderly.The pathogenesis of PD is intricate and involves multiple factors,with mitochondrial dysfunction recognized as a significant mechanism contributing to its development.MicroRNAs(miRNAs)play a crucial role in the onset and pro-gression of PD.This review focuses on recent research concerning miRNAs associated with PD,particularly their impact on mitochondrial dysfunction.The insights gathered here aim to support the early diagnosis and targeted treatment of PD.

Objective To investigate the current status,obstacles,and specific needs associated with the application of transradial access(TRA)in peripheral interventions in Chinese hospitals,with the aim of promoting the broader adoption of TRA in interventional procedures.Methods The Committee of Interventional Oncology of China Anti-Cancer Association conducted a cross-sectional questionnaire survey to investigate and analyze the nationwide situation of TRA in peripheral interventional surgeries in 2022.Results Personnel from 60 hospitals participated in the questionnaire.The results showed that the number of peripheral interventionals performed using TRA was significantly lower than that performed using transfemoral access(TFA),with considerable variability among hospitals.The primary obstacles to the adoption of TRA were the lack of suitable catheters and the difficulty of radial artery puncture.Approximately 86.67％of the institutions expressed a high expectation for the innovation of new TRA-specific devices,particularly catheters,microcatheters,and guidewires.60.00％of medical institutions indicated a strong desire for systematic training and participation in multi-center clinical trials.Conclusions TRA peripheral intervention is feasible in many hospitals in China,however,systematic training and further promotion of TRA are essential.The innovation of new TRA-specific devices and TRA in peripheral intervention is urgent.
