Study on the mechanism of Yangyin Yiqi mixture in the recovery period of pneumonia based on network pharmacology / 国际中医中药杂志

ABSTRACT

Objective:To study the mechanism of Yangyin Yiqi mixture on the clinical symptoms in convalescent period of different types of pneumonia based on network pharmacology, so as to provide more options for the prevention and treatment of pneumonia with Traditional Chinese Medicine (TCM).Methods:Based on the TCM theory of "treating different diseases with the same method", the Integrative Pharmacology-Based Research Platform of Traditional Chinese Medicine (TCMIP) V 2.0 was used to screen the active components, action targets and disease targets of the herbs in Yangyin Yiqi mixture. The disease-target-medicine network map was constructed by Cytoscape software and the Reactome enrichment analysis of key targets were carried out.Results:Seven different types of clinical sympotms of pneumonia in convalescent period were established, including fatigue, tachypnea, thirst, palpitations, hyperhidrosis, poor appetite and cough. After the screening, a total of 276 active components and 177 key targets were obtained, 37 common targets of this herb and pneumonia were obtained. The key targets were associated with cell metabolism, apoptosis, inflammatory response, immune response, and stress response, etc. There are 17 common targets between Polygonatum and 7 clinical symptoms in the recovery period of different types of pneumonia. Reactome enrichment analysis showed that the pathways involved in the core genes of Yangyin Yiqi mixture in the treatment of the main symptoms of different types of pneumonia in the recovery period were mainly enriched in by regulating genes and protein translation to affect the virus or cell function, immune regulation and inflammatory response and regulate the function of nervous system, and prevent viral canceration.Conclusions:The effective components in Yangyin Yiqi mixture may regulate phosphatidylinositol 3-kinase (PI3K), interleukin-4, interleukin-13 (IL-4, IL-13) and inhibitory kappa protein (IκBα) by intervention of PIK3CA, MAPK3, BCL2 and NF-κB2 and other targets to promote the recovery of pneumonia. This study could provide a theoretical basis for the prevention and treatment of pneumonia in the recovery period.
