Curative effect of edaravone in the treatment of patients with transient cerebral ischemia and its mechanism / 中国基层医药

ABSTRACT

Objective To study the curative effect of edaravone in the treatment of patients with transient cerebral ischemia and its mechanism.Methods 92 patients with TIA treated in our hospital from January 2015 to December 2015 were selected,they were randomly divided into observation group and control group,with 46 cases in each group.Both two groups were given conventional treatment,while the observation group added intravenous infusion of edaravone injection,two groups were treated for 2 weeks.Then,the efficacy and adverse reactions during treatment in two groups were compared.The levels of serum tumor necrosis factor alpha(TNF -α),transforming growth factor beta 1(TGF -β1)and matrix metalloproteinase -9(MMP -9)were detected by enzyme -linked immunosorbent assay(ELISA)in two groups before treatment and 1d,4d,7d,14d after treatment.The levels of high/low shear viscos-ity(HSV /LSV),plasma viscosity(PV),as well as fibrinogen(Fib)were also compared before treatment and 14d after treatment.Results The total effective rate of the observation group was 89.13%,which was significantly higher than 71.74% in the control group(χ2 =4.420,P <0.05).The levels of HSV,LSV,PV and Fib in two groups 14d after treatment were significantly lower than before treatment,which of the observation group were significantly lower than the control group,the differences were statistically significant(P <0.05).The serum levels of TNF -α[(5.99 ± 2.36)pg/mL,(5.82 ±2.34)pg/mL],TGF -β1 [(13.94 ±3.18)pg/L,(12.33 ±3.57)pg/L]and MMP -9 [(42.94 ±11.65)ng/mL,(38.26 ±17.58)ng/mL]in the observation group at 7d and 14d after treatment were sig-nificantly lower than before treatment,the differences were statistically significant (t =4.703,6.031,5.667;5.074, 7.623,6.150;all P <0.05),and which in the observation group were lower than the control group in the same peri-od,the differences were statistically significant(t =2.025,5.344,5.894;2.616,6.120,2.228;all P <0.05).The levels of above indicators 14d after treatment in the control group were significantly lower than before treatment,the differences were statistically significant(P <0.05).There were no serious adverse reactions in the two groups during the treatment.Conclusion Edaravone has obvious curative effect in the treatment of patients with TIA,which works by regulating the hemodynamic and the levels of TNF -α,TGF -β1 and MMP -9,it is safe and worthy of promotion.
