Effect of traditional Chinese medicine and compounds for supplementing qi and activating blood circulation and inducing resuscitation on regulating stem cells to promote nerve repair of acute ischemic stroke / 中国组织工程研究

ABSTRACT

BACKGROUND:Endogenous neurogenesis and exogenous stem cell transplantation in the brain show great therapeutic potential for neurological diseases including ischemic stroke,repairing and replacing lost neurons,promoting synaptic remodeling,and inhibiting apoptosis.Traditional Chinese medicine and compound therapy for supplementing qi,activating blood circulation and inducing resuscitation for the treatment of neurological dysfunction after ischemia have certain advantages,targeting nerve repair through a variety of ways,including promoting endogenous neurogenesis and exogenous stem cell survival,proliferation,homing,and inducing neuronal differentiation. OBJECTIVE:To summarize the mechanism of traditional Chinese medicine and compound for supplementing qi,activating blood circulation and inducing resuscitation to promote nerve repair in the acute phase of ischemic stroke,in order to provide a reference for the research and treatment of new drugs in ischemic stroke. METHODS:The articles from CNKI and PubMed databases about traditional Chinese medicine and compound for supplementing qi,activating blood circulation and inducing resuscitation in promotion of nerve repair in the acute phase of ischemic stroke from 2010 to 2022 were searched,with"supplementing qi and activating blood circulation;inducing resuscitation;traditional Chinese medicine(TCM);compounds;ischemic stroke;nerve repair;stem cells"as Chinese and English search terms.After excluding old and duplicate views,the retrieved literature was analyzed and collated,and a total of 124 articles were included for analysis. RESULTS AND CONCLUSION:(1)The definition of stem cells,ischemic stroke and the nerve repair pathway in the acute phase of ischemic stroke were sorted out.(2)The mechanism of action of traditional Chinese medicine and compound for supplementing qi,activating blood circulation and inducing resuscitation to promote nerve repair in the acute phase of ischemic stroke was summarized,mainly including promoting stem cell proliferation,improving stem cell viability and survival rate,promoting nerve cell homing,inducing stem cell differentiation to neurons,inhibiting apoptosis of nerve cells,promoting axon regeneration,regulating angiogenesis and remodeling,improving the level of neurotrophic factors and repairing the integrity of the blood-brain barrier.(3)Through the existing research,the relevant factors and signaling pathways of traditional Chinese medicines and compounds for supplementing qi,activating blood circulation and inducing resuscitation to promote nerve repair in the acute phase of ischemic stroke were summarized,such as Nestin protein expression,DCX protein expression,brain-derived neurotrophic factor,vascular endothelial growth factor and Wnt/β-catenin signaling pathway,Notch signaling pathway,PI3k/Akt signaling pathway,BDNF/TrkB signaling pathway and ERK/MAPK signaling pathway.It provides a relevant reference for future research on ischemic stroke-specific drugs and new clinical treatment methods.
