ABSTRACT
Abstract BACKGROUND: Large amounts of data have shown that Chinese herbal monomer has a neuroprotective effect, and can improve the quality of life in stroke patients with cerebral nervous system injury. Nuclear-factor-erythroid 2-related (Nrf2) factor has neuroprotective effect on hemorrhagic stroke and ischemic stroke, which is an important way to reverse the damage of nervous system through the natural non-toxic Chinese herbs or composition, but it is rarely reported systemicaly. OBJECTIVE:To summarize the neuroprotective effect of Chinese herbal monomersvia the Nrf2 signal pathway in stroke patients. METHODS:The first author retrieved the CNKI, VIP, Medline, and PubMed databases by computer. The keywords were “Nrf2, ARE, stroke, traditional Chinese medicine, neuroprotection” in Chinese and English,respectively. Articles concerning the neuroprotective role of Chinese herbal monomervia Nrf2 were analyzed and discussed. RESULTS AND CONCLUSION: Totaly 85 articles were retrieved. According to the inclusion and exclusion criteria, 46 articles were included in result analysis. The results show that a variety of monomers can exert neuroprotective effectsvia the Nrf2 pathway. Chinese herbal monomers include organic acids, phenols, saponins, terpenes, flavonoids, alkaloids, and other single or composite components. Traditional Chinese medicine has the clear neuroprotective effect after stroke, but it is lack of regularity, and it is stil need to expand the data and further research as the basis.
