ABSTRACT
Objective To investigate application of diffusion tensor tractography (DTT) on evaluating motor dysfunction degree of patients with cerebral infarction and explore the relationship between infracted focus and cortical spinal tract(CST).Methods Forty patients with cerebral infarctions in the different periods and 30 healthy volunteers were enrolled our study.They all underwent DTT check and then established CST.Meantime,all the patients were measured ADL score according to activities of daily living (ADL) on admission and two months after the onset.Results DTT image was made for both in patients and health control people.The CST was built in people in control group and its shape was like the adults'.Its shape was from the precentral gyrus down to internal capsule and continued to pontine and medulla oblongata.Each successive was form good consistency.The DTT image of patients' health side was like normal and injury corticospinal tract was affected by influence of infarction area at different level,manifested as loss of discontinuity and anatomical configuration consistency.Based on the degree of CST,there were 9 cases in grade Ⅰ,20 cases in grade Ⅱ and 11 cases at grade Ⅲ.DTT image showed that the damage level of CST had an negative relation with ADL score at 2 month after therapy (r =-0.914,P ＜ 0.05).Conclusion DTT can show the spatial positions of infarctions and CST at non-invasive lesion and analyze the influence of infarctions and corticospinal tract.Therefore,it can serve as the objective proof for judging the injury of the motor function and evaluating prognosis.
ABSTRACT
Objective To value the effect and safety of butyl phthalide sequential treatment in cerebral infarction of branch sclerosis of arterial congee appearance. Methods Sixty patients with acute cerebral infarction were randomly divided into treated group( n = 31)and control group( n = 29). According to the condition of illness,all patients were given aspirin,atorvastatin calcium,and the injection of ozagrel sodium intravenous;controlled the blood pressure,blood sugar,blood lipid,and treated complications posstively;take the early rehabilitation of nerve treatment afte the illness was in stable condition. Butyl phthalide was used in the patients of treated group(100 ml,twice per day,intravenous drip,during 14 days period therapy,and then 0. 2 g oral,third per day),besides the routine therapy. The degree of neural function defect score( NIHSS)and activities of daily living score(BI)between two groups were observed before and after treatment. Corresponding adverse consequences were recorded. Results Compared with pretreatment,the NIHSS of postreatment at the 14th day in treat and control groups were decreased(treated group:(4. 36 ± 3. 11)vs.(11. 42 ± 3. 20);control group:(6. 12 ± 2. 67)vs.(11. 64 ± 3. 43),P < 0. 05,and the treated group was significantly lower than control group(F inner groups = 2. 125,P < 0. 01;F between groups = 18. 63,P < 0. 01;F cross groups = 25. 34,P< 0. 01;P < 0. 05). The BI of postreatment in two group were increased(treated group:(86. 72 ± 8. 44)vs. (26. 54 ± 13. 36);control group:(75. 96 ± 9. 86)vs.(26. 38 ± 13. 02)),and the treated group was significantly lower than control group(F inner groups = 29. 27,P < 0. 01;F between groups = 32. 48,P < 0. 01;F cross groups= 42. 41,P < 0. 01;P < 0. 05). There was no the adverse reactions. Conclusion Butyl phthalide sequential treatment can improve the NIHSS and BI of cerebral infarction of branch sclerosis of arterial congee appearance and have a better therapy effect.
