ObjectiveTo detect the neuropsychological performances of vascular dementia(VD) and the varied patterns when the severity of VD progressed. Methods39 patients who fulfilled with National Institute of Neurological and Communicative Disorders and Stroke/the Alzheimer's Diseases and Related Disorders Association(NINDS AIREN) criteria for "probable vascular dementia"were assessed with the neuropsychological scales, including Mini Mental State Examination (MMSE), Blessed Dementia Scale (BDS), Clinical Memory Scale, Wechsler Adult Intelligence Scale Revised China (WAIS-RC) and Clinical Dementia Rating (CDR), to measure the change of orientation to time and place, memory, language, visuospatial skills, cognitive function, personality characteristics, the activities of social and daily living and self maintenance. Patients were divided into mild, moderate and severe categories according CDR scores.ResultsAmong mild, moderate and severe categories, significant differences (P<0.05) were detected in the following subtests: orientation to time of MMSE, digit span, block design, object assembly, arithmetic of WAIS-RC, memory quotient, the activities of social and daily living and self maintenance of BDS. In moderate/severe and mild/severe categories, significant differences (P<0.05) were detected in the MMSE language subtest, WAIS-RC comprehension subtest and verbal intelligence quotient. Significant differences were detected in MMSE orientation to time subtest and WAIS RC similarities subtest only between mild/severe categories (P<0.05). In the MMSE immediate or delayed recall, drawing, simple calculation subtests, and BDS personality subtest, no significant differences were detected among mild, moderate and severe categories (P>0.05). Conclusions Patients with mild VD showed general deterioration of orientation, memory, language, visuospatial skills, cognitive function, personality characteristics, the activities of social and daily living and self maintenance. However, the speed of deterioration of each item was different when the severity of VD progressed. No close correlation was observed between personality characteristics alteration and the severity of VD. From mild to moderate and moderate to severe VD, the speed of deterioration of part of the cognitive function, especially the knowledge ever acquired, was slow relatively. The other aspects continued deteriorating in all stages of VD.

Objective:To discuss the relationship between blood-lipid change and acute cerebrovascular disease (ACVD) and tocompare the blood-lipid levels in the patients with cerebral hemorrhage (CH group) with those in the patients with cerebralinfarction (CI group). Methods:The blood-lipid levels in 300 patients with ACVD (ACVD group) and 100 patients withother system disease (control group) were tested with automatic biochemistry analysor and compared between the twogroups. Results:There were significant differences between ACVD group and control group as well as between CH group andCI group. Conclusion:Although there were blood-lipid metabolic disturbances in both CH and CI patients, their degrees weresignificantly different, which should be closely observed and controlled in clinic.

To study the application of simulated-patient teaching in practice teaching and assessment of obstetrics and gynecology,the two groups of students were taught by simulated-patient teaching and discussed cases teaching respectively,and then they were assessed by using simulated patients for clinical skills.The result shows that simulated-patient teaching is effective in improving students' clinical skills,can act as a worthy tool of clinical teaching and assessment.

ObjectiveTo investigate the expression of caspase-3 in the brain of acutely pentylenetetrazole(PTZ)-kindled rats.MethodsThe caspase-3 positive cells were revealed using immunohistochemical SP method. CMIAS image analysis system was used to analyse the expression of caspase-3 hemi-quantitatively. ResultsFollowing PTZ induced epilepsy, the expression of caspase-3 increased both in the hippocampus and in the cortex, and that was more remarkable in the hippocampus than in the cortex.ConclusionCaspase-3 may be activated during neuronal apoptosis after epilepsy. Hippocampus is more sensitive to the neuronal damage due to epilepsy than the cortex is.

·AIM: To evaluate the recurrence rate and safety of amniotic membrane transplantation (AMT) augmented with mitomycin C (MMC) compared with amniotic membrane transplantation alone during the pterygium excision.·METHODS: We took a meta-analysis on this program.Pertinentstudieswereselectedthroughextensive searches of the Cochrane Library, MEDLINE, EMBASE,CBMdisc, CNKI. Pooled estimates were carried out in RevMan software V4.2.·RESULTS: Six trials reported postoperative recurrence rate of pterygium, included 882 eyes, three trials reported the complications. The results of meta-analysis showed that recurrence rate of AMT plus MMC group was 5.41％,AMT alone group was 16.89％, relative risk (RR) was 0.32, 95％CI ranged from 0.19 to 0.56, Zwas 4.06, P< 0.001. Two trials reported early complication as punctata keratitis, the incidence rate of AMT plus MMC group and AMT alone group were 17.14％ and 0.00％, RR was 12.11,95％CI ranged from 1.62 to 90.76.·CONCLUSION: Amniotic membrane transplantation with MMC is associated with lower recurrence rate compared with amniotic membrane transplantation alone in pterygium excision,whether accompanied a higher risk with adverse events need more investigation.
