卫生职业学校实验教学管理

卫生职业学校实验教学是整个教学过程中重要的实践性环节,其教学内容一般分为演示型实验、观察型实验、验证分析型实验、模拟操作型实验四种类型。实验的方法有以下几项教学目的:一是实验操作技术的掌握和熟练;二是理论联系实际,深入理解和巩固运用课堂所学理论知识;三是观察、     

Pediatric intracranial aneurysms——clinical characteristics and therapeutic strategies

Objective To assess the radiological characteristics and therapeutic strategies of intracranial aneurysms in children. Methods From our dedicated neurovascular databank of patients, we reviewed 23 consecutive children who had 24 intracranial aneurysms. There were 14 boys and 9 girls with a mean age of 9.09 years ( range 1 - 14 years ). Results Intracranial aneurysms in children ≤ 14 years constituted 1.3% of all intracranial aneurysms. Internal Carotid artery (ICA) and middle cerebral artery (MCA) were the most frequent sites for aneurysms. About 58.3% of the aneurysms were complex, including dissecting, pseudoaneurysm, giant and fusiform aneurysm. 1/3 of all aneurysms were located in posterior circulation. Only 1 case had multiple aneurysms in this case series. Almost half of all cases presented with subarachnoid hemorrhage and others presented with mass effect. 14 cases underwent endovascular treatment. 4 patients received microsurgical therapy. 5 cases did not receive microsurgical or endovascular therapy, 2 of them whose aneurysms spontaneously thrombosed during follow up. One boy with left vertebral artery giant aneurysm died after endovascular therapy owing to gradual thrombosis in basilar artery. Another child had poor outcome because of rerupture of aneurysm before operation. Whereas the majority had a favorable outcome. Conclusions Intracranial aneurysms in children had many clinical and radiological characteristics different from those in adults : ( 1 ) remarkable male predominance; ( 2 ) ICA and MCA were the most common sites for aneurysms; (3) high incidence of large, traumatic, infectious, dissecting and fusiform aneurysms. (4)For pediatric intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. Endovaacular therapy was the best choice for complex aneurysms.     

距小腿关节运动损伤的常见因素

距小腿关节是人体中比较复杂和重要的关节,发生损伤的几率很高。对于距小腿关节损伤,虽然多数人通过治疗可以康复,但仍有20%左右的患者将转为慢性损伤或伤残。有鉴于此,探讨距小腿关节损伤的机制、找出距小腿关节损伤的原因及掌握预防的措施,是体育教学、运动训练和大众体育活动中迫切需要解决的问题。     

30例腹腔镜手术的临床体会

腹腔镜手术具有创伤小、出血少、恢复快的优点,因此在妇科手术中得到了广泛的开展。我院从2000年12月至2001年7月开展腹腔镜手术30例,取得了满意的临床效果,现报告如下。     

创伤性膈疝21例临床分析

我院自１９８９年３月至１９９５年１０月手术治疗２１例创伤性膈疝，２１例疝愈。 发病机理与胸腹腔压力差、腹腔脏器冲击膈肌及胸腔负压有关。同时简要介绍了创伤性膈疝的诊断和治疗。
