Ganglioglioma: a clinicopathological study of 19 cases / 临床与实验病理学杂志

Purpose To study the clinicopathologic features of ganglioglioma. Methods The clinicopathologic data of the cases pathologically diagnosed as ganglioglioma that underwent resection of epileptic focus were retrospectively analyzed. Results In the 19 cases studied, the mean onset age was 9.1 years, and the duration of disease was 9.3 years. MRI images showed abnormal signals. The majority of the site was temporal lobe (14/19, 73.7％). The tumors showed heterogeneity and often accompanied by focal cortical dysplasias (13/19, 68.4％). Immunohistochemical staining showed CD34 positive in 18 cases, Nestin positive in 16 cases, and BRAF-V600E positive in 6 case. The positive expression rate of CD34 and Nestin did not have significant differences. Conclusion The diagnosis of ganglioglioma relies on pathological observations combined with clinical features and neuroradiological examinations. Differential diagnosis should be done from other tumors or cortical dysplasia. Immunohistochemical staining of CD34 and Nestin can help diagnosis.

Survey on aspirin application and ischemic stroke recurrence among elderly patients in Shanghai community hospitals / 上海第二医科大学学报

Objective To investigate the application status of aspirin for secondary prevention among elderly patients with ischemic stroke in some community hospitals in Shanghai,and explore the main causes for inappropriate use of aspirin and the effect of aspirin on the prevention of ischemic stroke recurrence. Methods The cross-sectional investigation was employed,and 223 patients from 10 community hospitals of Shanghai were divided into regularly-received aspirin group(n=98) and irregularly-received aspirin group(n=125).The application status of aspirin was investigated and the relationship between aspirin application and ischemic stroke recurrence was explored. Results Fifty-one cases in irregularly-received aspirin group(40.80%) stopped aspirin use or reduced the dose due to possible adverse effects,which accounted for 22.87% of the total population investigated,and 42 cases in irregularly-received aspirin group(33.60%)were never suggested to use aspirin or only used traditional Chinese medicine.The rate of ischemic stroke recurrence was 30.61%(30 cases) in regularly-received aspirin group,and 49.60%(62 cases) in irregularly-received aspirin group,which existed significant differences between these two group(P
