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.     

启发式教学在生理学教学中的应用研究

针对生理学课程理论抽象、实验操作复杂等特点,阐述了启发式教学方法取代传统填鸭式教学方法的必然性。因生理学教学难度大、实验操作条件高,故着重介绍了问答式、讨论式、演绎式、归纳式、直观式等五种启发式教学方法在生理学教学中的应用。     

项灵汤治疗气滞血瘀型颈椎病的作用

应用经验方项灵汤治疗60例气滞血瘀型颈椎病患，并设60例西药治疗对照组。对比两组治疗前后纤维蛋白原(Fg)和超氧化物歧化酶(SOD)的改变情况。结果显示中药治疗组较西药治疗组有更好的治疗效果，能更明显降低血液黏稠度，抑制体内过氧化物生成，从而达到行气活血的目的。     

食用味精“四不宜”

(1)不宜在碱性或酸性强的食品中使用。谷氨酸钠中的钠活性甚高,容易与碱发生化学反应,产生一种具有不良气味的谷氨酸二钠,失去调味作用。用于酸性菜肴中则不易溶解,使调味效果受到影响。 (2)炒菜时不宜放入过早,炒菜起锅后放味精,温度降至70-90℃左右加入,此时的溶解度最好。在高温时加用,当温度超过120℃时味精中的谷氨酸钠就会变成焦化的谷氨酸钠,焦化     

脸色腰段椎间盘突出症21例临床分析

胸腰段椎间盘突出症罕见,约占椎间盘突出的0.6％～4％。随着CT及MRI的应用,其发病率有增加的趋势。因其发病率低,报道较少。但由于病变位于脊髓圆椎段,其发病较下腰段椎间盘突出有很大的特殊性,故有必要结合我院近年收治的21例对其作一回顾性分析。1 临床资料     

耳垂复合组织游离移植修复鼻小柱过短畸形

目的 探讨因鼻小柱过短所致鼻尖低平畸形的矫治方法.方法 对8例鼻尖低平伴鼻小柱过短者,采用鼻小柱切口,首先应用肋软骨或Medpor行支撑杆移植矫正撑起鼻尖,鼻小柱切口的继发创面采用耳垂复合组织游离移植修复.结果 8例游离移植的耳垂复合组织均成活良好,随访1～2年形态满意,色泽与周围组织无明显差别,供区无明显继发畸形.结论 应用耳垂复合组织游离移植修复鼻小柱过短畸形,不仅适用于外伤性缺损修复,而且也适用于鼻部的美容性修复,是一种患者容易接受、操作简单安全、疗效好、供区无后遗明显继发畸形的修复方法.

用科学发展观构建新形势下医院的建设与发展

改革开放20多年来，医院在医院规模、学科人才、技术水平、服务保障能力及经济增长等诸多方面均获得了巨大进步，谋求下一步可持续发展是大家十分关心的热点问题。随着国家医疗卫生体制改革和机制创新的不断深入，使医院正面临着外部市场、环境政策变革与内生性增长受限这种前所未有的新形势。如何适应新形势，迎接新挑战，用科学发展观谋划新发展，值得我们深入研究和思考。
