RESUMO
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.
RESUMO
ObjectiveTo investigate predictive value of matrix metalloproteinase-9 (MMP-9) and Interleukin-6 (IL-6) combined with cervical length in premature delivery.MethodsPlasma samples of 62 pregnant women were detected in this study.Samples were divided into three groups based on pregnancy outcomes.MMP-9 and IL-6 values were determined by ELISA.Cervical length was measured by transvagihal sonography.ResultsThe level of MMP-9 of the pregnant women in the premature delivery group was significantly higher than that of continuous pregnant group and that of normal pregnant women [(47.24 ±6.41) ng/ml,(523.24 ± 62.35) pg/ml vs (20.39 ±7.23 )ng/ml,(219.29 ± 80.23)pg/ml,(32.18 ±5.16)ng/ml,(406.18 ±71.52) pg/ml,P ＜0.01].The level of MMP-9 and IL-6 of the pregnant women in the continuous pregnant group was significantly higher than that of normal pregnant women [(32.18 ±5.16)ng/ml,(406.18 ±71.52) pg/ml vs (20.39 ±7.32) ng/ml,(219.29 ± 80.23) pg/ml,P ＜0.01].Cervical length of the pregnant women in the premature delivery group was significantly shorter than that of normal pregnant women and that of continuous pregnant group [( 15.62 ± 2.31 )mm vs ( 31.05 ± 1.48 )mm,(26.14 ±3.12)mm,P ＜0.01].ConclusionsDetection of level of MMP-9 and IL-6 combined with measurement of cervical length can be used as predicting index of premature delivery.
