Objective To explore the characters of cognitive dysfunction for first-ever lacunar infarction (LI). Methods 136 first-ever diagnosed LI patients were evaluated with Alzheimer's disease assessment scale (ADAS) 72 h, 2 weeks, 1 month, 3 months and 6 months after attack. The scores were compared with the baseline and those of 76 normal control. Results Memory: during the first 72 h, significant difference was shown between the every location of LI (including the basal ganglia, corona radiate,frontal lobe, temporal lobe,parietal lobe, periventricular location, centrum semiovale, thalamus) and normal control (P<0.05); but between the certain location of LI and that of normal control 2 weeks, 1, 3 and 6 months after attack (P<0.05). Language: there was significant difference between every location of LI and normal control 72 h, 2 weeks and 1 month after attack (P<0.05), but between the certain location of LI and that of normal control 3 and 6 months after attack (P<0.05). Practice: there was significant difference through every visit time point of all the LI patients compared with normal control (P<0.05). Attention: Significant difference (P<0.05) was found between every location LI patients and normal control 72 h after attack, but between certain location LI patients and normal control 2 weeks, 1, 3 and 6 months after attack (P<0.05). Orientation:LI was insufficient to cause to decline in orientation. Conclusion There are mild to severe cognitive dysfunctions in the first-ever diagnosed LI patients, which need pay attention to and intervene in time.

Objective To explore the diagnosis value of CT in subarachnoid hemorrhage(SAH) induced by aneurysm rupture.Methods The clinical and CT data of 119 patients with SAH induced by aneurysm rupture were analyzed respectively.Results The CT characteristic of SAH induced by aneurysm rupture was full of hyperderse in sulcus and schizenceplay,or accompaning intracerebral hematoma in the straight gyrus of frontal lobe and the hippocampal gyrus of parietal lobe.Conclusion The CT has important value for diagnosing SAH induced by aneurysm rupture in the location and the nature.But it is indispensable that the CTA or DSA must be done for ascertaining the artery of responsibility of rupturing aneurysm.

Objective To discuss the diagnosis and treatment of AVM bleeding without DSA in the basic hospital.Methods Clinical difference of intracerebral hemorrhage was revienly analyzed between arteriovenous malformation and hypertensive intracerebral hemorrhage.Results Boths were different at sick ages,position and shape of haematoma,change of blood pressure after bleeding,CT scan of preoperative and view in operative.Surgery was effective.Conclusion Initial diagnosised of AVM bleeding is affirmed,according to patient's age,using mannitol is effective to control blood pressure after bleeding and display of CT scans preoperative.Final diagnosis is confirmed in operation without DSA at basic hospital.Treatment of AVM bleeding with surgery is effective.

Objective To explore the characteristics of cognitive function in patients with leukoaraiosis(LA)at different extent.Methods The cognitive function of 66 patients with different extent of LA and 49 healthy controls were measured using the MoCA scale,and the relationship between the cognitive function and the extent of LA was evaluated.Results The LA was more severe,the cognitive function of patients was more poor.The cognitive function of patients with type Ⅳ LA significantly decreased than the patients with type Ⅰ LA and the controls,especially in the language,memory,visuoconstructional and executive functions(P<0.05).While the function of naming,attention,abstraction and orientation showed no significant difference between the patients with LA and the controls(P>0.05).Conclusion Moderate and severe LA may cause impairment of cognitive function.

Objective To study the effect of hyperbaric oxygen on cognitive dysfunction in patients with leukoaraiosis (LA). Methods 48 cases of moderate or severe LA with cognitive dysfunction were divided into 2 groups: the experimental group accepted hyperbaric oxygen (HBO) besides routine therapy, while the control group accepted routine therapy only. Both groups were assessed with Montreal cognition assessment (MoCA). Results The scores of MoCA in patients in the experimental group improved after treatment（P<0.05）, and was more than that of the control group（P<0.05）. Conclusion HBO can improve the cognitive function in patients with LA.

Objective To compare the effect of difierent combinatio of mannitol, furesemide and albumin in reducing intracranial pressure in 451 patients with severe traumatic brain injury (sTBI). Methods A total of 451 patients with an admissiou Glasgow Coma Scale of or less from 5 medical centers were randomly divided into 5 groups, ie, Group A(250 ml 20% mannitol each time as control), Group B(125 ml 20% mannitol each time), Group C(alternate use of 250 ml 20% mannitol each time or 40 mg furosemide), Group D(alternate use of 125 ml 20% mannitol each time and 20 mg furosemide)and Group E(alternate use of 125 ml 20% mannitol and moderate or large dose of albumin). We monitored intracraniai pressure continuously and observed the changes of intracranial pressure, electrolytes, hemato-crit and renal function after use of 5 combinations of mannitol. Furosemide and albumin. Results Man-nitol and furosemide could independently reduce intracranial pressure after 1-3 hours (P<0. 05). Semis mannitol plus furosemide or albumin could more signifieantly reduce intracranial pressure, with statistical difference compared with full dose of mannitol. Semis mannitol and alternate use of mannitol and furose-mide in aspect of intracranial pressure reduction and persistence time(P<0. 05). Alternate use of man-nitol and furosemide begot higher incidence rate of electrolyte abnormality, compared with the other com-binations (P<0. 05). Rebound rate of intracranial pressure was higher in full dose of mannitol than other combinations (P<0. 05). Incidence of renal function abnormality was higher in combination involved al-bumin than alternative use of mannitol and furosemide as well as combination of semis mannitol and furo-semide (P<0. 05). Abnormality of electrolyte and renal function wag reversible. Conclusion The use of 125 ml 20% mannitol each time plus 20 mg furesemide is more reasonable than other combina-tions. Meanwhile, semis mannitol combined with moderate or large dose of albumin has certain advantages too.

Objective - To analyze the relation between classes and prognosis of the brain.stem hemorrhage.Methods 37 patients with spontaneous brainstem hemorrhage were divided into three groups according to con-sciousness and breathing function: Ⅰ group 13 cases with consciousness; Ⅱ group 11 cases without consciousness; Ⅲgroup 13 cases without consciousness and respiration, according to the classes, using different ways and means.
