By random sampling,we investigated 276 graduate students of Huazhong Normal University in Wuhan for their understandings on euthanasia.The survey data showed that only a few students have a clear recognition of euthanasia,and no more than 50% of the students investigated accepted active or passive euthanasia,while the acceptance of passive euthanasia was less than 25%.However,the students realized that individuals have the right for euthanasia since they considered euthanasia as a humanitarian behavior,and they hoped certain legislations would be soon available.The students with different backgrounds including genders,majorities,and origins of hometowns(from urban or suburban areas) all have influences on their understanding of euthanasia.Therefore,more extensive investigations are in great need for the future legislation of euthanasia.

Objectives:To study the clinical significance of electron beam CT with three-dimensional reconstruction in evaluating acetabular fractures.　Methods:Twenty-six cases of acetabuar fractures were examined under X-ray and 3D reconstruction. Degrees of displacement were evaluated and classified for the selection of therapy.　Results:The 26 cases of acetabuar fractures were: 1 case of anterior column fracture,3 cases of posterior column fracture,11 cases of posterior wall fracture,4 cases of transverse fracture, and 7 cases of compound fracture. All the 26 cases were accurately evaluated by EBCT 3D image, according to the image, appropriate surgical treatment were applied to 15 cases, and 11 cases were treated nonoperatively.　Conclusions:EBCT 3D reconstruction could revealed the characteristics of acetabular fractures, which aided the evaluation and selection of therapy, increased the veracity of procedures and reduced the unnecessary operations.
