Objective:To evaluate the efficacy and safety of dl-3-butylphthalide ( NBP) injection and soft capsules in the treat-ment of acute middle cerebral artery infarction. Methods:Sixty-one patients with acute cerebral infarction in the left middle cerebral artery in 72 hours of onset of ischemic stroke with score of 5-25 according to the national institutes of health stroke scale ( NIHSS) were randomly divided into the observation group (n=31) and the control group (n=30). The control group was treated with the routine treatment, while the observation group was sequentially treated with NBP injection and soft capsules additionally. The treatment course was 90 days. Before the treatment, the NIHSS score was evaluated in both groups to compare the neurologic impairment degree. After the treatment, the daily living skills assessment was performed by Barthel index ( BI) and modified Rankin score ( mRS) , and the ad-verse reactions were recorded. Results:Before the treatment, the NIHSS score in the two groups had no statistical significance ( P>0. 05). After the treatment, the BI in the observation group and the control group was (88. 55 ± 16. 74) and (70. 67 ± 26. 18), and mRS was (1. 87 ± 1. 02) and (2. 53 ± 1. 40), respectively, suggesting the observation group had more favorable outcome than the con-trol group (P≤0. 05). The incidence of adverse reactions had no significant difference between the groups. Conclusion: dl-3-Bu-tylphthalide sequential therapy should be regarded as an effective and safe method for acute cerebral infarction, which can improve the daily living skills and 90-day outcome of patients.

Objective:To observe the effect and its mechanism of hemoperfusion on injured myocardium under acute toxication of methomyl in rabbits. Methods:Twenty-four rabbits were randomly divided into three groups:control group ( N group) , acute metho-myl intoxication group ( P group) , hemoperfusion group ( HP group) . P group and HP group was treated by methomyl intoxication, and with 2-hour sham-hemoperfusion and hempoperfusion respectively. Then the pathological changes of myocardium were observed under optical microscope. The activity of SOD and content of MDA in myocardium were measured by colorimetry. The experimental data were analyzed by SPSS 16. 0 package. Results:There were congestion, edema and other pathological changes in group P, while no obvious changes in N group and HP group. The activity of SOD decreased while MDA content increased in P group versus N and HP group ( P< 0. 05). Conclusion:Hemoperfusion can alleviate the myocardial injury induced by methomyl poisoning through the mechanism of the resistance to oxidative damage.

To explore the incidence and risk factors for spontaneous hemorrhagic transformation (HT) of cardioembolism (CE,n =150) and large artery atherosclerotic infarction (LAA,n =370).The incidence of HT was 29.3％ in CE.And it was significantly higher than 9.7％ (P ＜0.05).Infarct size,low-density lipoprotein-cholesterol (LDL-C) and admission National Institutes of Health Stroke Scale (NIHSS) score were independent predictors of spontaneous hemorrhagic transformation in LAA.OR values were 3.92,2.96 and 1.45 respectively.Infarct size,admission NIHSS score and random blood glucose level were independent predictors of spontaneous hemorrhagic transformation in CE.OR values were 4.86,2.42 and 1.42 respectively.As compared with LAA,CE was more prone to HT.LAA and CE-related factors of hemorrhagic transformation are not completely identical.

ObjectiveTo evaluate prognosis and its clinical factors in patients with primary pontine hemorrhage. Methods Patients with primary pontine hemorrhage who were hospitalized in the First Affiliated Hospital of Wenzhou Medical College within 24 hours after stroke onset between April 2007 and April 2009 were registered conscutively. The patients were followed up for one year. Kaplan-Meier methods were used to analyze survival rate. Cox proportional hazards model was used to study risk factors for 1-year mortality. ResultsA total of 41 patients with primary pontine hemorrhage were studied. Their mean age was (63.5 ± 10. 1 ) years.The overall 1-year mortality rate was 61.0％, the median survival time was (80. 0 ±54.4) days (95％ CI 0-186. 64). After one-year follow-up, the mortality rate in patients with primary dorsal pontine hemorrhage( 18.2％ ) was significantly lower than that in patients with primary ventral pontine hemorrhage(72. 7％ ; x2 = 8. 800, P = 0. 003 ). Patients with massive primary pontine hemorrhage had significantly higher mortality rate than patients with dorsal primary pontine hemorrhage( x2 = 8. 927, P =0. 003). The average hematoma volume of the survivor group and mortality group was (3. 043 ± 1. 718) ml and (5. 984 ± 2. 707) ml, respectively, showing statistical significance (t = 3. 661, P = 0. 001 ). Analysis with Cox proportional hazards model showed that the risk factors associated with mortality were hematoma location ( RR = 2. 428, 95 ％ CI 1. 055-5. 587 ), hematoma volume ( RR = 1. 283, 95 ％ CI 1. 044-1. 577 ),GCS score on admission(RR =3. 389, 95％ CI 1. 177-9. 756). Patients with pontine hematomas in dorsal had a significantly better outcome than in other locations.Conclusions The survival and prognosis in primary dorsal pontine hemorrhage are better than with hemorrhaging in other parts of pontine. A significant correlation was observed between poor prognosis and hematoma volume, hematoma location and GCS score on admission.
