Objective:To evaluate of value of 64-slices spiral CT angiography(CTA)in the etiological diagnsis of subarachnoid haemorrhage(SAH).Methods:CTA was performed in 89 cases with spontaneous SAH admitted from September 2005 to September 2006,49 of whom also underwent digital subtracted angiography(DSA).The findings of CTA were compared with the results of DSA.Results:Among the 89 patients,CTA revealed 69 cases with cerebral aneurysm,9 arteriovenous malforma- tion(AVM),2 thrombus of venous sinues,8 negative findings.Among the 49 patients who underwent both CTA and DSA,all but 1 lesions showed by CTA,either cerebral aneurysms(n=41)or AVMs(n=4),were confirmed by DSA.DSA failed to show one case of small anterior communicating aneurysm demonstrated by CTA.It was found that CTA sensitivity and specificity was 100% and that DSA sensitivity was 98% and specificity was 100% in diagnosis of intracranial aneurysms in etiological diagnosis of SAH.Conclusion:64-slices spiral CTA is a non-invaise,fast convenience imaging modality for etiological diag- nosis of the SAH and also play an important role in selecting therapy and assessing difficulties of treatment.

In the occurrence and development of neurological diseases,it often accompanied by cognitive impairment,which severely decreases the quality of life of the patients.Therefore,it is necessary for patients with neurological diseases to rapidly screen cognitive function.This aricle reviews the advances in research on the brief cognitive rating scales commnly used in clinical.

There is a close relationship between high trans fatty acids intake and occurrence of metabolic syndrome. Trans fatty acids intake may lead to metabolic disorders. It affects lipid level, induces visceral obesity and insulin resistance, triggers systemic inflammation, and significantly increases cardiometabolic risks. If the chain of trans fatty acids-metabolic syndrome-cardiovascular disease is understood, a new effective way to prevent metabolic syndrome and cardiovascular events may be provided.

3.64 mmol/L)received 8-week double blind comparisons treatment.After treatment we randomly selected 15 patients for each group.The fasting serum lipid was measured at the end of 4-week and 8-week,and the serum hs-CRP and IL-6 were measured too.Meanwhile seven hypercholesterolemic patients from rosuvastatin group and seven ortholiposis out-patients were included.These patients were treated with statins for 4 weeks.The erythrocytes before and after treatment were kept to be measured the FA.Results (1)Compared with the pretreatment,the level of LDL-C,TC,hs-CRP remarkably reduced in two treatment groups at the end of 4-week therapy.These inflammatory parameters did not further reduced,but hs-CRP reduced further at the end of 8-week therapy.(2)The percent age of SFA was obviously higher in hypercholesterolemic group than ortholiposis group.On the other hand,PUFA and ?-3 FA were obviously lower.After 4-week treatment the percent age of SFA reduced,while PUFA and ?-3 FA increased significantly in hypercholesterolemic group.Conclusion (1)Statins reducing inflammatory factors is independent of lipid-modifying ability.(2)Rosuvastatin treatment can effectively reduce the level of LDL-C and TC,and no significant difference in the effect is observed between two treatment groups.(3)The erythrocyte membrane FA proportion was obviously different in hypercholesterolemic group from ortholiposis group.Statins treatment could make the proportion of FA in erythrocyte membrane restore normal.

Objective To explore the effects of microsurgical technique treatment on acknowledge ability ,activities of daily liv-ing ,cortex blood perfusion and neuropeptide levels of brain glioma patients .Methods Microsurgical technique treatment and tradi-tional operation were given to 87 brain glioma patients ,respectively .The acknowledge ability and activities of daily living were measured by HDS ,MMSE and ADL ;the cortex blood perfusion were revealed by PET ,and the neuropeptide levels including argi-nine vasopressin ,oxytocin ,β-endorphin ,somatostatin and neurotensin of patients from two different surgical groups were compared . Results As compared with the traditional operation ,the acknowledge ability and activities of daily living of patients from microsur-gical treatment group were significantly improved(P<0 .05) ,the cortex blood perfusion were statistically increased (P<0 .05) and the levels of five kinds of neuropeptide were all profoundly increased (P< 0 .05) .Conclusion Microsurgical technique treatment could improve the acknowledge ability and activities of daily living of brain glioma patients ,the mechanisms of which could be the increase of cortex blood perfusion and theincrease of neuropeptide levels .

Objective To investigate the changes of antibrain-antibody (AB-Ab) in blood serum and the effect of AB-Ab on blood-brain barrier (BBB) and cerebral edema after the traumatic brain injury (TBI) in rabbits.Methods Forty-five New Zealand rabbits were randomly divided into control group (n =5),sham operation group (fenestration only without injury,n =15) and TBI group (severe lateral fluid percussion brain injury,n =15) according to the random number table.Sham and TBI animals were subdivided at postoperative 1,3,7 and 14 days.Level of AB-Ab,BBB permeability and brain water content were determined after operation.Results At each time point,serum AB-Ab level,BBB permeability and brain water content were higher in sham operation group and TBI group than in control group (P ＜0.05).At postoperative 3,7 and 14 days,serum AB-Ab level,BBB permeability and brain water content were higher in TBI group than in sham operation group (P ＜ 0.05).Conclusion Serum level of AB-Ab is significantly increased after TBI along with synchronous changes in BBB permeability and brain water content,indicating that AB-Ab may be associated with the increase of BBB permeability and brain edema.

Objective To observe the dynamic change of brain natriuretic peptide (BNP) in plasma of elderly patients with hy-pertensive intracerebral hemorrhage ,and to explore the relationship between BNP levels and cerebral edema .Methods 56 elderly patients with hypertensive intracerebral hemorrhage were recruited and divided into the operation group (n=26) and the non-opera-tion group(n=30) ,25 hypertensive patients were collected as the control group .ELISA was applied to detect the levels of plasma BNP at 6 ,24 ,72 ,168 h after the onset of hypertensive intracerebral hemorrhage .The non-invasion brain edema monitor was utilized to dynamically monitor the cerebral edema degrees .Results The plasma BNP levels in the operation group and the non-operation group at 6 ,24 ,72 ,168 h were higher than those in the control group ,the differences showed statistical difference (P<0 .05) ,but which at 168 h in the operation group was lower than that in the non-operation group ,cerebral edema appeared at 24 h in the two groups ,and reached the peak value at 72 h in the operation group and at68 h in the non-operation group;the changes of plasma BNP levels had positive correlation with cerebral edema degree (r=0 .685 ,P<0 .05) .Conclusion Dynamic monitoring of plasma BNP levels is an effective indicator for early diagnosis and monitoring of acute brain edema in elderly patients with hypertensive in-tracerebral hemorrhage .
