OBJECTIVE:To explore the prognosis effect of Shengmai injection to the rt-PA thrombolysis on broadened thera-peutic window patients of mild-to-moderate cerebral infarction under the guidance of computer tomography(CT). METHODS:168 patients with mild-to-moderate cerebral infarction were randomly divided into control group (84 cases) and observation group (84 cases). Control group received rt-PA(0.9 mg/kg),and 10% of the total rt-PA was mixed and injected into patients within 1 min, the rest 90% adding into 250 ml 0.9% Sodium chloride injection (no less than 1 h),CT was performed after 24 h thrombolytic therapy,and the patients with no intracerebral hemorrhage in re-examination received 300 mg/d aspirin for 10 d,then 100 mg/d for 90 d,and appropriate statins,calcium antagonists,β-blockers and nitrates;observation group additionally received 40 ml Sheng-mai injection,adding into 250 ml 5% Glucose injection,intravenous infusion,once a day,for 28 d. National Institutes of Health Stroke Scale (NIHSS) score,Rankin score,daily living-Barthel Index (Barthel) score,rate of symptomatic intracranial hemor-rhage,rate of secondary hemorrhage,hospitalization time,3-month postoperative mortality and incidence of adverse reactions in 2 groups were observed. RESULTS:Before treatment,there were no significant differences in the NIHSS score,Rankin score and Barthel score(P>0.05). The NIHSS score in 2 groups after 6 h,24 h and 7 d were significantly lower than before,and observa-tion group was lower than control group after 24 h and 7 d;Rankin score after 3 months was significantly lower than before,and observation group was lower than control group;Barthel score after 3 months was significantly higher than before,and observation group was higher than control group,The differences were statistically significant (P<0.05). The hospitalization time in observa-tion group was significantly shorter than in control group,and 3-month postoperative mortality was significantly lower than control group,the differences were statistically significant(P<0.05). There were no obvious adverse reactions during treatment. CONCLU-SIONS:Based on conventional treatment,Shengmai injection has improvement in the rt-PA intravenous thrombolysis on broadened therapeutic window patients of mild-to-moderate cerebral infarction under the guidance of CT,it can reduce NIHSS score and Rankin score,increase Barthel score,shorten hospitalization time and reduce the 3-month postoperative mortality,with good safety.
