研究目的:

本研究以耐药敏化量效、时效关系为主线,通过耐药敏化筛选、敏化稳定性及遗传稳定性、敏化机制研究及敏化药效学验证,从基因、细胞、功能蛋白水平揭示TRQ与抗生素联用协同增效机制,确定痰热清对呼吸道感染主要耐药菌中哪种菌敏化作用最强、与哪种抗生素联用效果最佳,并在临床水平上进行验证。研究将揭示TRQ与抗生素联用协同增效机制,为指导临床精准用药提供选择依据;为中药敏化耐药菌提供可推广的研究实例,为控制耐药菌感染提供快速应对新策略。

Objectives of Study:

In this study, the dose-effect and time-effect relationship of drug resistance sensitization is the main line. Through drug resistance sensitization screening, sensitization stability and genetic stability, sensitization mechanism research, and sensitization pharmacodynamics verification, from genes, cells, and functional proteins. To reveal the synergistic mechanism of the combination of TRQ and antibiotics, determine which combination has the strongest sensitization effect on the main drug-resistant bacteria in respiratory tract infections, and with which antibiotics have the best combined effect, and verify at the clinical level . The study will reveal the synergistic mechanism of TRQ combined with antibiotics, and provide a basis for selection of clinical precision medicine; provide a generalizable research example for sensitized and resistant bacteria of traditional Chinese medicine, and provide a new strategy for rapid response to the control of drug-resistant infection.
