RESUMEN
Objective:To explore the relationship between Feng syndrome(风证) and plasma endothelin(ET)in initial condition of acutely ischemic stroke.Methods:Using the table of syndrome quantitative diagnosis which formulated according to experiences of apoplectic experts to grade the fraction of syndrome which appears in initial condition of 151 cases with acute cerebral infarction，at the same time the level of plasma ET was determined by radioimmunoassay(RIA),and then according to the fraction of syndrome patients were divided into two groups,one is Feng syndrome group,the other is nonFeng syndrome group，the levels of plasma ET in this two groups and with healthy subject were compared.Results:It showed that the level of plasma ET in Feng group was significantly higher than that in nonFeng group（P<0.001）；and the same result between the patients and the healthy subjects（all P<0.001） were obtained.Conclusions:The results demonstrate that there is a correlated relationship between Feng syndrome and plasma ET,and the level of plasma ET can be regarded as a microcosmic indices to separate Feng syndrome from nonFeng syndrome.
