Objective To explore the correlation of cognitive impairment with ischemic strokeinducing cerebral artery,in order to predict and find the correlations between different cognitive dysfunction and different intracranial arterial occlusion.Methods We used Montreal Cognitive Assessment (MoCA) to evaluate neuropsychological statuses in the 250 patients,who developed first time acute myocardial infarction for 2 weeks.MoCA scores and other neuropsychological cognitive assessment scores were recorded.Patients were grouped by the location of intracranial arterial occlusion.The neuropsychological cognitive assessment results were analyzed between groups.Results Middle cerebral artery occlusion was correlated with impairments of visual spatial/executive,attention,language and memory (B=-1.875 ～-1.094,P＜0.05).Anterior cerebral artery and vertebral basilar artery occlusion had correlations with attention impairment (B =-3.977,B =-1.833,P＜0.01).Posterior cerebral artery occlusion could cause visual spatial/executive,language and memory impairment(B=-1.714 ～-1.095,P＜0.05).No correlation of cognitive impairment characteristics with anterior choroidal artery occlusion was found.Conclusions Different arterial occlusion can cause different characteristics of impairment in cognitive function,which can help to predict cognitive impairment after sub-acute stroke.It suggests that some cognitive assessments must be conducted in sub-acute stroke management.

Secondary pancreatic infection in severe a-cute pancreatitis (SAP) was associated with mortality and the length of stay in hospital.Intensive Care Unit (ICU) identificate shock on account of the oxygen metaboilic level in earlier period of SAP and perform adequate fluid resuscita-tion.it advocate to perform organ function support and/or substitution therapy in time and think highly of coordination and combination each other among various kinds therapeutic measure.These therapeutic concept and measure will con-duce to decrease the incidence rate of MODS and secondary pancreatic infection accordingly in SAP.

Objective To analyze the reliability and validity of the Chinese version of the Rivermead Behavioural Memory Test-Third Edition (RBMT-III). Methods The items of RBMT-III were translated in Chinese and adjusted. A total of 131 healthy subjects were tested with Chinese version of RBMT-III, 30 of them were tested again with other materials two weeks later. Results The Cronbach'sαcoefficient was 0.799. The correlation coefficient of parallel-forms in subtest scale and meory index were all more than 0.65. There were six main fac-tors extracted, which explained 64.47%of the accumulated variance, those were novel task learning, spatial memory, verbal memory, visual memory, prospective memory and orientation/date. Conclusion RBMT-III is a reliable and validated instrument for assessment of memory.

Objective To explore the characteristics of brain activation when solving simple multiplication and complex multiplication tasks. Methods From June, 2010 to June, 2012, Thirteen normal subjects completed four functional magnetic resonance imaging (fMRI) ex-periments, including control tasks, visuospatial memory tasks, simple (single-digit) multiplication tasks and complex (multi-digit) multiplica-tion tasks. Results Compared with the control tasks, visuospatial memory tasks activated the bilateral occipital lobe, the right precuneus and superior parietal lobe;simple multiplication tasks activated the bilateral middle occipital gyri, the left superior parietal lobe, the left cingu-late gyrus, the left middle frontal gyrus and inferior frontal gyrus;complex multiplication tasks activated the right superior parietal lobe, the right inferior frontal gyrus, and the bilateral middle frontal gyri. Conclusion A right parieto-frontal network is involved in the multi-digit multiplication, which supports the containing of the spatial layout information.

Objective To elucidate the effect of rehabilitation training on visual reaction times of children with brain injury. Methods Fifty-one children with brain injury recruited for the observation group were observed, 29 age-matched normal children served as the controlsubjects. All the children in both groups were tested in terms of the eye-hand visual reaction times(VRTs). All the patients were given rehabilitation treatment. Results Before rehabilitation treatment, the VRTs of the observation group were significantly slower than those of the control group (P0.05). Conclusion The attention and the motor speed were abnormal in children with brain injury, rehabilitation treatment can improve the reaction times significantly. The test of RTs could be of great importance in the evaluation of neurobehavior and therapeutic effect for children with brain injury, because of its easiness, sensitiveness and objectiveness in clinical application.

ObjectiveTo observe the characteristic of reaction times (RTs) in the brain injury children.Methods65 children with brain injury, including 50 cerebral palsy (CP) cases, 13 brain trauma (BT) cases and 2 other cases, were selected as the experimental group, and 29 age-matched normal children as the control group. Children of two groups were tested by the eye-hand visual reaction times (VRTs), and children of the experimental group were also tested with Wechsler preschool and primary scale of intelligence (WPPSI), Wechsler intelligence scale for children (WISC-R) and comprehensive function assessment.ResultsThe VRTs of the experimental group children was significantly slower than that of the control group (P<0.01). There was no significant difference in VRTs test between CP and BT children (P>0.05). The motor time of VRTs of the severe subjects in the experimental group was significantly slower than that of moderate and light subjects (P<0.01). There was a negative correlation between VRTs and the scores of IQ, PIQ and the comprehensive function assessment.ConclusionThe attention and the motor speed of muscles are abnormal in children with brain injury.

Objective To test the impact of age, education and gender on the Chinese Version of the Test of Everyday Attention (TEA).Methods 117 normal volunteers were selected. They were grouped by age and education. After screening of Montreal Cognitive Assessment (MoCA), the volunteers were administered to the TEA (version A). Correlation analysis was performed between age and education with TEA. Comparisons between groups were tested in gender. Results There were significant correlations between most subtests with age except elevator counting, visual elevator counting (VE1) and lottery task. Education correlated with map search and elevator counting with reversal in the youth group. There were correlation between visual elevator (VE2) and telephone search while counting with education in the young and middle-aged group. Education related to map search, visual elevator (VE1, VE2), elevator counting with reversal, and telephone search in the middle-aged group. The subtests were not statistically different between different gender groups except telephone search. Conclusion Age and education had effect on TEA while Gender had no significant effect.

Objective To explore the reliability and validity of the Chinese version of the Test of Everyday Attention (TEA) in normal Chinese people. Methods 117 normal volunteers (18～65 years old) were screened with the Montreal Cognition Assessment (MoCA), and the normal volunteers were administered to TEA (versions A), Trail Making Test B (TMT-B), Paced Auditory Serial Addition Task (PASAT), Stroop Color-Word Interference Test (SCWT), Continuous Performance Test (CPT). 20 normal volunteers were also given version B for testing of the test-retest reliability, time interval was 2 weeks between versions A and B. Results There was correlation between versions A and B in the major subtests (r>0.700, P<0.01) at a two-week interval. The varimax rotation principal-component analysis extracted 4 component factors, namely sustained attention, se lective attention, switching attention, and divided attention. The factors included various subtests of TEA and the other laboratory attentional test. Conclusion TEA has good reliability and validity.

Objective To investigate the perceptual priming in brain injured patients. Methods 41brain injured patients, including 24 brain injury and 17 stroke. 99 normal controls, including 39 young, 39 middle aged and 21elderly people. All of them were estimated by the Fragmented Picture Naming Task. Results The patient group had lower priming scores than the young (t=5.558, P<0.001), and middle and elderly-aged (t=3.100, P=0.003) control group in the Fragmented Picture Naming Task. Conclusion Perceptual priming is not only concerned with occipital lobe, but also with frontal and temporal lobes possibly.
