Objective To explore the clinical significance of measurement on the changes of serum Hey,hs-CRP and TGF-pilevels after treatment in patients with ACE. Methods Serum Hcy(with immunochemistry) , serum hs-CRP (with immunoturbidime-try) , serum TGF-β1 (with RIA) levels were determined in 32 patients with ACI and 35 normal healthy controls. Results Before treatment,serum Hcy,hs-CRPand TGF-pl levels in the patients were significantly higher than those in controls (P <0.01). After treatment for 1 month,serum Hey, hs-CRF and TGF-pl levels were no significant difference (P >0.05). Serum Hey level showed positively correlated with hs-CRP,TGF-pl levels (r=0.6146,0.5784,P<0.01). Conclusion Detection the changes of serum Hey, hs-CHP and TGF-pl levels after treatment in patient with ACI might be helpful to monitor efficacy of therapy and prognosis. Therefore, possess important clinical value.TGF
