长链非编码RNA失调在脑动脉瘤发病机制中的潜在作用研究

目的：通过分析动脉瘤中异常表达的lncRNA，探讨其在动脉瘤的发生发展中可能发挥的重要功能。方法：检测5例颅内动脉瘤患者的动脉瘤组织与正常颅内动脉组织中的lncRNA表达谱和mRNA表达谱，并探寻异常表达的lncRNA所靶向的mRNA。结果：lncRNA芯片分析结果显示，与正常血管比较，血管瘤组织中存在1533种异常表达的lncRNA，其中520种lncRNA表达上调，1013种lncRNA表达下调。274种异常表达的lncRNA分别靶向于188种异常表达的mRNA，共形成了434对lncRNA和mRNA靶向关系。靶mRNA相关的信路分析显示，focal adhesion信号通路可能发挥了至关重要的作用。对lncRNA基因与靶mRNA互作关系的网络分析显示，lncRNA n345160、XR_171115.1、NR_027671.2和ENSG00000261903.1在动脉瘤发生中可能发挥了重要作用。结论：lncRNA可能在颅内动脉瘤发生发展中发挥了重要作用。同时lncRNA与编码蛋白的mRNA之间可能存在复杂的相互作用，这或许能为临床探索预防与治疗颅内动脉瘤的方法提供新的理论基础。     

颅内蛛网膜囊肿致典型三叉神经痛1例

1病例资料49岁女性,因反复出现阵发性右面部疼痛5个月入院。主要为鼻唇沟到下颌角区域尖锐的放电样疼痛。常在吃饭或者刷牙时出现,数分钟后可以自行缓解。疼痛发作频率从开始时的每日数次发展到每日数十次,并且口服卡马西平片的剂量已经达到0.6 g/d,症状仍不能明显缓解。     

磁共振血管造影在颅内动脉瘤诊断中的应用价值分析

颅内动脉瘤是蛛网膜下腔出血的重要病因,是在脑动脉腔内压力增高或先天性缺陷基础上发生的内腔局限性的异常扩大,进而导致动脉壁的瘤状突出[1]。该疾病会导致患者出现呕吐、剧烈头痛、视力障碍等临床症状,如不及时治疗,会导致动脉瘤破裂,引发大出血,引发脑水肿、蛛网膜下腔出血等疾病,甚至危及患者的生命安全。临床上,常用数字减影血管造影(DSA)、磁共振血管造影(MRA)等进行诊断颅内动脉瘤。作为诊断该疾病的金标准,DSA检查不仅可以动态展示血管的充盈情况,还可以对血液循环时间进行计算,从而开展血管内的治疗性操作[2]。

侧脑室联合蛛网膜下腔持续引流治疗继发性脑室出血

继发性脑室出血通常是由于高血压性脑实质出血直接穿破所致,是一种病情凶险,病情复杂,并发症多,病死率很高的急性脑血管病,总死亡率达83.3% [1] ,目前国内外治疗方法不一。2 0 0 1年1月至2 0 0 3年10月我院采取超早期侧脑室引流,术后蛛网膜下腔置管持续引流治疗继发性脑室出血2     

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.     

低颅压综合征1例报告

低颅压综合征并非少见,常被误诊,尤其是当腰穿见到血性脑脊液时,常被诊断为蛛网膜下腔出血,而进行很多不必要的检查,给病人及家属造成过重负担。现将笔者遇到的1例低颅压综合征病例报告如下。1临床资料患者女,40岁。既往健康,无头部外伤史和腰穿史。入院3天前跑步后发生额部疼痛,为持续性疼痛,恶心、呕吐2次,无发热和周身不适;卧床时头痛明显减轻,坐起或站立后头痛很快加重。在厂医院对症治疗不见好转来诊。来诊时查体:意识清楚,血压正常,未查到任何神经系统阳性体征。头颅CT未见异常。腰穿脑脊液:初压为60 mm H2O,脑脊液黄染,常规检查蛋…
