[Biological essence of blood stasis-heat syndrome in ischemic stroke and current research status of traditional Chinese medicine prevention and treatment based on thromboinflammation reaction].

Abstract

Blood stasis-heat syndrome is one of the common syndromes of ischemic stroke, which is manifested as syndromes of blood stasis and heat during the pathological progression of patients with ischemic stroke, but there is a lack of systematic research on its biological essence. Thromboinflammation reaction is a newly proposed pathological mechanism highly associated with thrombosis and inflammatory reaction, and it refers to the fact that under the mediation of von Willebrand factor(vWF) and the kallikrein-kinin system, thrombosis and inflammatory reaction interact with each other. Activation of T cells and neutrophils further aggravates thrombosis and worsens the pathological progression of ischemic stroke. Therefore, thromboinflammation reaction has the characteristics of the interaction between blood stasis and heat in blood stasis-heat syndrome in traditional Chinese medicine(TCM). Based on the research progress related to thromboinflammation reaction and the clinical syndrome characteristics and biomarkers of blood stasis-heat syndrome in ischemic stroke, this paper put forward the view that thromboinflammation reaction may be the biological foundation of blood stasis-heat syndrome in ischemic stroke. Besides, this paper systematically organized the current applications and research on the mechanism of TCM monomers or compound formulas with the effects of promoting blood circulation to remove blood stasis and clearing heat and detoxifying. It is found that the pharmacological mechanisms are intimately linked to the regulation of biomarkers related to thromboinflammation reaction, verifying that the biological foundation of the blood stasis-heat syndrome in ischemic stroke is thromboinflammation reaction. This paper aims to provide a scientific basis for TCM prevention and treatment strategies for ischemic stroke targeting thromboinflammation reaction.
