幽门管溃疡206例内镜下特点

在内镜下，幽门管溃疡是指发生在幽门通向十二指肠球部一段长约0．5～1．0cm管腔的溃疡，属消化性溃疡的特殊类型。我们经内镜检出206例，现将其特点总结如下。     

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.     

疾病对心理的影响和心理护理对策刍议

疾病是人体对外界事物与环境变化的反应过程，而此过程对机体造成了生理和心理上的重大影响，使机体的正常生理和心理出现失衡状态。要恢复机体的平衡必需要通过相应的措施，特别是针对心理变化的改善对策。良好的心理护理会使疾病的恢复“事半功倍”。     

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     

紫外分光光度法测定沙棘中黄酮的含量

沙棘是蒙古族和藏族习用药材，具止咳，祛痰，活血，祛“巴达干”等功效，主要用于咳嗽，痰多，慢性气管炎，肺脓肿等病症。为了控制本品的内在质量，采用紫外分光光度法测定沙棘中有效成分黄酮的含量。     

AMPK在妊娠期糖尿病发病机制中的作用

腺苷酸活化蛋白激酶是一种重要的蛋白激酶,主要作用是协调代谢和能量平衡.腺苷酸活化蛋白激酶被激活后,在增加骨骼肌对葡萄糖摄取、增强胰岛素敏感性、增加脂肪酸氧化以及调节基因转录等方面发挥重要作用.已经证实脂联素有调节糖脂代谢的作用,但其作用机制尚不十分清楚,很可能是通过腺苷酸活化蛋白激酶介导,对脂联素信号转导通路的研究将成为进一步理解脂联素作用的关键所在.而脂联素又是妊娠期糖尿病的预测因子,所以腺苷酸活化蛋白激酶逐渐成为对妊娠期糖尿病研究中的焦点.     

前列肿消栓的部分药理学及病理学研究

目的:探讨前列肿消栓治疗慢性前列腺炎的药理学作用。方法:1,急性毒性及直肠粘膜刺激性试验;2,对角叉菜所致小鼠足跖肿胀的影响;3,对非细菌性前列腺炎病理模型影响的预试验。结果:前列肿消栓对直肠粘膜无刺激性,最大给药量为233.8g/kg(原生药);该栓剂能明显抑制角叉菜所致小鼠足跖肿胀;病理检查结果显示:前列肿消栓能明显减轻前列腺腔内及间质的炎细胞浸润,抑制纤维母细胞的增生,改善腺腔的分泌。结论:前列肿消栓具有明显的抗炎作用;对直肠粘膜无刺激性,最大给药量为233.8g/kg(原生药),按成人体重60kg计算,小鼠最大给药量相当于成人日用量的139.5倍,可以提供临床应用。     

巡回性诊疗护理与老年人保健

饭富病院地处日本本州山黎县,远离大都市,地偏人稀,但环境优美,气候宜人,的确是疗养的好地方。饭富病院属公立医院,虽规模较小,但是一所综合性医院。我们在此院研修3个月,时间虽短,但期间的所见所闻,尤其护理方面给我们的启发和教益却是十分深刻的。现介绍几个片断,以飨读者。1
