DSA对老年性颈内动脉重度狭窄或闭塞患者侧支循环的应用价值

Objective To investigate the diagnostic value of aortocranial DSA in collateral circulation in elderly patients with serious stenosis or occlusion of the internal carotid artery. Methods Twenty-three elderly patients with serious stenosis or occlusion of the internal carotid artery, admitted to our hospital from August 2008 to July 2010, were chosen; their DSA findings and prognoses were retrospectively analyzed. Results Of these 23 patients, the collateral circulation was seen in 18(78.3%), including compensations from anterior communicating artery (n=16), posterior communicating artery (n=6), anterior together with posterior communicating artery (n=3), anterior choroidal artery (n=5),meningina artery between anterior cerebral artery and posterior cerebral artery (n=5), meningina artery between posterior cerebral artery and middle cerebral artery (n=4), ophthalmic artery (n=15), blood vessel between posterior cerebral artery and superior cerebellar artery (n=3), and blood vessel among superior cerebellar artery, anterior inferior cerebellar artery and posterior inferior cerebellar artery (n=2); after conservative treatment and long time follow-up (1 to 22 months with a mean of 11.2 moths),disappearance of clinical symptoms and no recurrence were found in these 18 patients. Five patients were noted without compensatory collateral circulation: the 2 paralysis patients could not take care of themselves even with the improvement of myodynamia from grade 0 to grade Ⅲ; the 2 patients with disturbance of consciousness showed no recovery and died from lung infection; the left 1 patient was having aphasia. Conclusion DSA can accurately define ways and compensative ability of collateral circulation in elderly patients with serious stenosis or occlusion of the internal carotidartery, which can put forward reliable evidences for their treatments and prognoses.     

辛醇对红藻氨酸诱导癫痫大鼠海马Caspase-3表达的影响

癫痫可引起急性和持久性中枢神经系统损害,易致海马神经元损伤.细胞凋亡是癫痫发作后神经元死亡的主要形式之一.研究表明,癫痫发作后导致持续长时间的神经元凋亡可能是癫痫发作脑损害的重要机制[1].     

骨扫描中的超级骨显像

骨扫描敏感性高且能够同时显示全身骨骼的代谢变化,受到了临床医生的极大重视.超级骨显像最初由Osmond等[1]在1975年提出,其通常是指全身骨骼显影较软组织明显增强,而肾脏则显影浅淡甚至不显影.     

脑卒中患者IL-18及CRP血清水平检测分析

目的探讨脑卒中患者血清白细胞介素18（Interleukin-18,IL-18）及C-反应蛋白（c—reactiveprotein,cRP）含量变化的临床意义。方法将98例脑卒中患者分为脑梗死组（52例）,脑出血组（46例）,同期选择健康体检者38例为对照组,分别检测其治疗前和治疗后5天的血清IL-18和CRP的浓度。根据神经功能损伤程度评分标准将患者分为轻度损伤组（32例）、中度损伤组（46例）和重度损伤组（20例）。结果脑卒中患者治疗前血清IL-18及CRP明显高于对照组（P〈0．05）,且治疗后比治疗前明显下降（P〈0．05）,并随着脑神经功能损害的加重而升高（P〈0．05）。结论IL-18及CRP在脑卒中发病过程中起促进作用,与脑神经受损程度相关。     

Cx43磷酸化及其与ZO-1、Src相互作用的研究进展

<正>缝隙连接(Gap Junction,GJ)是沟通相邻细胞胞质的细胞间通道,介导缝隙连接细胞间通讯(GJIC),缝隙连接蛋白(Connexin,Cx)是实现GJIC的结构基础,主要通过对细胞信号的传导来发挥作用。近年来随着分子生物学发展,有学者认为这种     

PET和PET-CT在宫颈癌中的应用价值

宫颈癌是妇科常见的恶性肿瘤,18F-FDGPET或PET-CT作为一种功能显像技术,对宫颈癌的早期发现、肿瘤的良恶性判断和恶性程度评价、肿瘤的临床分期、各种治疗后的疗效评估和复发的判定等方面具有很高的临床价值。PET-CT通过解剖和功能图像的融合技术提高了诊断的准确性。     

癫痫持续状态并发全身炎症反应综合征致多器官功能障碍综合征的临床研究

目的探讨癫痫持续状态(SE)并发全身炎症反应综合征(SIRS)致多器官功能障碍综合征(MODS)的可能机制,揭示肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)在SE并发SIRS及向MODS转化机制中的作用及病理生理意义。方法观察78例SE患者并发SIRS及MODS的发生率;应用双抗体夹心(ELISA)法测定其血清TNF-αI、L-1β的动态变化,并与32名健康人进行对照比较。结果SE时并发SIRS的发生率为47.44%(37/78),其中56.76%(21/37)诱导发生MODS。单纯SE组、SE致SIRS组和SE致MODS组患者血清TNF-α、IL-1β水平均明显高于正常对照组(均P<0.01),并呈逐渐升高趋势,与病情的严重程度相关。结论SE并发SIRS是导致MODS的主要机制,TNF-αI、L-1β参与了SE并发SIRS及导致MODS发生、发展的病理生理过程,并具很高的预警价值。     

天麻素对癫痫患者炎症因子、脑源性神经营养因子水平的影响

目的 探讨天麻素对癫痫患者炎症因子、脑源性神经营养因子(BDNF)水平的影响.方法 选取120例癫痫患者,随机分为观察组与对照组各60例.对照组服用卡马西平治疗,观察组同时服用卡马西平和天麻素治疗.治疗2个月后,比较两组肿瘤坏死因子α(TNF-ɑ)、白细胞介素-6(IL-6)、C反应蛋白(CRP)及BDNF的表达水平.结果 治疗2个月后,观察组TNF-ɑ、IL-6、CRP水平均低于对照组(P<0.05),BDNF水平高于对照组(P<0.05).两组的不良反应发生率比较差异无统计学意义(P>0.05).结论 天麻素联合卡马西平治疗癫痫可有效降低患者炎症因子水平,并能提高BDNF水平,临床上可用于癫痫的辅助治疗.
