[Effect of modified Buyang Huanwu Decoction on hemorrhagic transformation after rt-PA intravenous thrombolysis in patients with super early cerebral infarction].

To study the effect of modified Buyang Huanwu Decoction on the hemorrhagic transformation after intravenous thrombolysis of recombinant tissue type plasminogen activator(rt-PA) in patients with super early(onset time<4. 5 h) cerebral infarction. From March 2016 to July 2018,at the brain disease zone of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine,212 cases of super early cerebral infarction were selected and divided into two group according to the randomized complete blocks designs: control group(106 cases) and traditional Chinese medicine group(106 cases). The control group was treated with rt-PA intravenous thrombolysis,while the traditional Chinese medicine group was treated with modified Buyang Huanwu Decoction in addition to the therapy of the control group. Both groups were treated for 14 days. Neurological deficit score,serum matrix metalloproteinase-9(MMP-9),neuron specific enolase(NSE),vascular endothelial growth factor(VEGF) and plasma cellular fibronectin(c-FN) levels,the incidence of hemorrhagic transformation,clinical efficacy and adverse drug reactions before and after treatment were compared between the two groups. According to the findings,at the 14 thday after treatment,the rank sum test of the grade data showed that the clinical efficacy of the traditional Chinese medicine group was better than that of the control group(Z =-2. 033,P = 0. 042); on the basis of χ2 test,the total efficiency of the traditional Chinese medicine group was higher than that of the control group(χ2= 4. 895,P =0. 027); the hemorrhagic transformation rate of the traditional Chinese medicine group was lower than that of the control group within14 days of treatment(χ2= 3. 962,P = 0. 047). MMP-9 levels in the traditional Chinese medicine group were lower than those in the control group at the 3 rd,5 th,7 th,10 th,14 thd after treatment(t =-2. 474,-3. 022,-5. 163,-6. 998,-9. 821; P = 0. 014,0. 003,0,0,0). The improvement of c-FN,NSE,VEGF and NIHSS scores in the traditional Chinese medicine group was superior to that of the control group after 14 days of treatment(t =-2. 343,-3. 187,-2. 129,-3. 105; P = 0. 020,0. 002,0. 034,0. 002). No obvious adverse reactions of modified Buyang Huanwu Decoction were observed during 14 days of treatment. Modified Buyang Huanwu Decoction could reduce the expressions of MMP-9,c-FN,NSE and VEGF after rt-PA intravenous thrombolysis in patients with super early cerebral infarction,and decrease the hemorrhagic transformation rate after thrombolysis,with high safety.
