微流控芯片技术及质谱技术用于细菌耐药性检测及耐药机制研究

细菌耐药性严重影响全球公共卫生安全。抗生素错用和滥用不仅没有达到治疗细菌感染性疾病的效果，反而会刺激细菌发生DNA损伤修复反应（SOS反应），加剧细菌耐药性的进化和耐药菌的传播。本文聚焦于耐药菌，简明介绍细菌耐药性与SOS反应，系统概述了质谱技术、微流控技术及其联用技术在细菌检测及细菌耐药机制研究中的应用。本文为细菌耐药性相关的药物靶点挖掘及新药开发提供理论参考，以期发展细菌耐药性快速检测新方法和抑菌新方法，推动临床细菌感染性疾病的诊断与治疗。

Microfluidic chip and mass spectrometry-based detection of bacterial antimicrobial resistance and study of antimicrobial resistance mechanism

Bacterial antimicrobial resistance (AMR) is a globally serious problem that threatens public health security.Misuse and abuse of antibiotics cannot achieve the effect of treating bacterial infectious diseases, but will trigger the SOS response of bacteria, exacerbating the evolution of bacterial AMR and the spread of resistant bacteria.This article focuses on antibiotic-resistant bacteria, briefly introduces the pathogenesis of bacterial AMR and SOS response, and systematically summarizes the determination and mechanism study of bacterial AMR based on microfluidics and mass spectrometry.This article provides theoretical basis for AMR-related drug target mining and new drug development, aiming to develop new methods for rapid detection of bacterial AMR and new methods for bacteria inhibition, and promote the diagnosis and treatment of clinical bacteria infectious diseases.
