Abstract:
Objective To investigate the effect of intravenous thrombolytic therapy with urokinase on the neurological function and the concentration of serum matrix metalloproteinase 9 (MMP-9) in the patients with acute cerebral infarction.Methods The patients with acute cerebral infarction were divided into the experimental and control groups.The experimental group included 27 patients who were complied with thrombolytic criterion within 4.5 hours after stroke and were firstly treated by intravenous thrombolytic therapy with urokinase by 100 million units after 24 h and 300 mg aspirin by oral.The control group included 27 cases that were directly administrated by 300 mg aspirin 4.5 hours later after stroke.After 24 h,the two groups were administrated with other same conventional treatments such as neurotrophy,improvement of microcirculation,and control of blood-fat.The neurological function and dynamic concentration of serum MMP-9 were observed before treatment and after treatment.Results After treatment,the neurological deficit evaluation score in both groups was gradually reduced with the treatment time,and the neurological deficit evaluation score in the experimental group was significantly lower than that in the control group at the 1 st,3rd,and 14th day,respectively[(10.97 ± 1.53) Score vs (15.67 ±1.78)Score,t =8.35,P =0.03;(8.15 ± 1.40) Score vs(12.72 ± 3.31) Score,t =6.62,P =0.03; (5.87 ± 1.03) Score vs (11.92 ±2.05) Score,t =13.70,P =0.01].After treatment,the concentration of serum MMP-9 in both groups was reduced with the treatment time,and serum MMP-9 in the experimental group was significantly lower than that in the control group at the 1st,3rd,and 14th day,respectively[(282.84 ±37.51) ng/ml vs (316.90±36.75)ng/ml,t =3.37,P =0.00;(309.11±37.71)ng/mlvs (348.39 ±15.26) ng/ml,t =5.02,P=0.04;(264.68±31.91)ng/ml vs (302.81 ±36.30)ng/ml,t =4.10,P =0.03].Conclusions Intravenous thrombolytic therapy with urokinase can effectively reduce the neurological deficit and the produce of MMP-9 in patients with acute cerebral infarction.
