浅表性胃炎患者胃液氨浓度测定

目前，国内对胃氨浓度的测定方法及正常值，胃氨浓度与浅表性胃炎的关系报道较少，为了探讨我国成年人胃氨浓度正常值及对浅表性胃炎疾病的影响程度，以我院就诊患为对象，内镜下用胃管取胃液并测定氨浓度。现将结果报告分析如下。     

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.     

上胸椎前方手术入路

上胸椎前方解剖关系复杂，由浅及深为肌层：颈阔肌，胸锁乳突肌；骨性结构：胸骨柄，胸锁关节；血管性结构：左、右颈总动脉，主动脉弓，无名动脉，左无名静脉，左、右头臂静脉，甲状腺下动脉，胸导管；神经组织：喉返神经，交感神经链；其他深层组织：食管，气管，甲状腺，胸腺。这些器官和组织相互交错，互为邻里，错综复杂。此处椎体或脊髓前方病变时，前方入路可直接暴露病变部位，术野清晰，手术直接，效果明确，但易损伤以上相邻组织，严重者损伤胸髓，导致患者高位截瘫。

逆行交锁髓内钉治疗股骨下段骨干并髁上髁间粉碎性骨折

近年来由于交通及煤矿事业的发展，高能量损伤越来越多，股骨下段骨干并髁上髁间严重粉碎性骨折有所增多，属影响了关节面的骨折，对它的治疗必须进行手术处理，但以往难以找到可靠的处理方法，我科于2001年2月到2005年2月共收治了26例，采用了逆行交锁髓内钉固定并取髂骨植骨取得了较好的疗效。报告如下：     

对芸香科芦荟不会发生接触性过敏

芦荟自古就被用作化妆品和药物添加剂，近来更受喜爱。虽应用广泛，但过敏反应罕有报道。作者用芦荟叶的油性提取物、来自整个植株的芦荟粉及浓缩的芦荟凝胶，对相继就诊的702例患者做斑贴试验。设计专门的问卷调查芦荟的使用、使用原因、使用部位、不良反应、患者职业、个人爱好及是否为遗传性过敏体质。患者均未对任一制剂发生任何反应。需对芦荟所含的两种成分加以鉴别：即芦荟叶皮含有的具有促进肠蠕动、潜在抗菌及抗癌特性的蒽醌类物质。
