Résumé
Objective:The present study was designed to strengthen the education of research integrity, and to improve the awareness of academic misconduct and academic literacy of medical post-graduate students.Methods:A questionnaire survey was conducted with master post-graduate students of a university affiliated hospital, and statistical analysis on the education of research integrity and the perception of academic misconduct among the survey respondents was performed.Results:Academic master post-graduate students′ cognitions of the misconduct in scientific research process and overall academic misconduct were better than that of professional master post-graduate students, and there were significant differences ( P<0.05). The more times of participation in research integrity training, the better cognition of misconduct of scientific research process, research results publication process, and overall academic misconduct, with significant differences ( P<0.05). Conclusions:The education on scientific research integrity of medical post-graduates should be carried out systematically, while the content should be improved and the form should be enriched for scientific research integrity education, so that the medical post-graduates can have a deeper understanding of the code of academic practices, and an education model of scientific research integrity for medical post-graduate which is suitable for China′s national conditions can be gradually developed.
Résumé
Objective To investigate the clinical characteristics and mechanism of cavernous sinus dural arteriovenous fistula (CSDAVF). Methods The clinical data of 17 CSDAVF patients, including clinical manifestations, characteristics of cerebrospinal fluid (CSF)and neuroimaging,were analyzed.The interventional catheter embolization of CSDAVF and postoperative follow-up were performed. Results Of the 17 subjects with CSDAVF, 5 (29.4%) were men and 12 (70.6%)were women (sex ratio=1:2.4).The average age of onset was (58.12±14.61)years old. Older CSDAVF patients were prone to be complicated with hypertension than general population at the same age. Onset symptoms included headache in 6 cases,eye symptoms in 5 cases,intracranial murmur in 2 cases,diplopia in 2 cases, dizziness in 1 case and slurred speech in 1 case. Digital subtraction angiography (DSA) was performed in all 17 patients. Further embolization was applied in 14 patients and had satisfactory outcome. In CSDAVF patients with headache, 2 patients showed orthostatic headache as initial symptom. One of them with intracranial hypotension reported exophthalmos 3 months after the onset. Those two patients remained asymptomatic during 3-year and 2-year follow-up after receiving interventional catheter embolization for CSDAVF. Conclusions CSDAVF usually occurs in middle-aged and older women, especially in those with hypertension. CSDAVF varies in clinical manifestations. A special attention should be given to orthostatic headache which can be presented as the initial symptom in few patients with CSDAVF. CTA or DSA should be considered in patients with clinically suspected CSDAVF to rule out the possibility of CSDAVF. The interventional catheter embolization is the primary treatment of CSDAVF.
