Research progress of traditional Chinese medicine in regulating autophagy for intervening in diabetic cardiomyopathy
Diabetic cardiomyopathy(DCM)is a chronic complication of diabetes mellitus that leads to cardiac damage in the later stages of the disease,and its pathogenesis is complex,involving metabolic disorders brought about by a variety of aberrant alterations such as endoplasmic reticulum stress,oxidative stress,inflammation,and apoptosis,defects in cardiomyocyte Ca2+transporter,and myocardial fibrosis.Currently,there is a lack of specific diagnosis and treatment in the clinic.Autophagy is a highly conserved scaven-ging mechanism that removes proteins,damaged organelles or foreign contaminants and converts them into energy and amino acids to maintain the stability of the intracellular environment.Inhibition of autophagy can cause harmful metabolites to accumulate in the cell,while over-activation of autophagy can disrupt normal cellular structures and cause cell death.Prolonged high glucose levels disrupt car-diomyocyte autophagy levels and exacerbate the development of DCM.The protective or detrimental effects of autophagy on cells ring true with the traditional Chinese medicine theory of healthy Qi and pathogenic Qi.Autophagy in the physiological state of the removal of intracellular substances and the generation of substances beneficial to the survival of cells is the inhibition of pathogenic Qi to help the performance of healthy Qi,so the organism is healthy.In the early stages of the disease,when autophagy is impaired and incapable of removing waste substances,pathogenic Qi is prevalent;In the later stages of the disease,excessive activation of autophagy can destroy normal cells,leading to a weakening of healthy Qi.Traditional Chinese medicine has the advantage of targeting multiple sites and path-ways.Studies in recent years have confirmed that traditional Chinese medicine monomers or formulas can target autophagy,promote the restoration of autophagy levels,maintain mitochondrial and endoplasmic reticulum homeostasis,and reduce oxidative stress,endoplas-mic reticulum stress,inflammation,and apoptosis in order to prevent and control DCM.This study provides a review of the relationship between autophagy and DCM and the intervention of traditional Chinese medicine in autophagy for the treatment of DCM,with a view to providing new clinical ideas and methods for the treatment of DCM with traditional Chinese medicine.
