预防精神病人自杀的护理干预

有资料显示,精神病人的自杀死亡率达6.0%[1],有的报道达22.7%[2].精神病病人自杀给家庭、社会带来的诸多问题,以成为精神科临床工作关注的重点.我院2001年-2004年对59例因自杀而入院的精神病病人进行护理干预,取得了满意的效果.现介绍如下.     

超顺磁氧化铁标记骨髓基质干细胞移植治疗帕金森病鼠的实验研究

目的:研究应用超顺磁氧化铁(SPIO)标记骨髓基质干细胞(MSCs)移植治疗帕金森病(PD)大鼠后的在体MRI观察。方法:分离、获取大鼠骨髓基质细胞,脂质体转染法将SPIO标记MSCs;制作PD模型,SPIO标记的MSCs移植到PD大鼠右侧纹状体区,应用MRI在体观察脑内移植的骨髓基质细胞的存活和迁徙情况。结果:体外SPIO标记的骨髓基质细胞普鲁蓝染色阳性;脑内移植SPIO标记MSCs的PD大鼠磁共振T2和T2GRE扫描检查显示在移植区呈低信号改变。随时间的延长,移植区信号向周围扩大。脑纹状体区的铁染色也可见SPIO标记MSCs从移植部位向四周迁移。结论:SPIO可用于体外标记MSCs,通过MRI技术可以对标记细胞脑内移植后进行初步的活体示踪,有利于MSCs移植治疗PD后的疗效观察。     

Structural shielding design for a gamma ray stereotactic body radiotherapy system.

An OUR-QGD gamma ray stereotactic body radiotherapy system (body knife), made in China, is described. According to its structure and the principle of gamma radiation revolved on a focus, the energy distribution of scattered radiation in its treatment room is calculated. The structural shielding of the wall, roof, and door for a certain treatment room is calculated according to the local radiation protection law.

Ruptured distal anterior choroidal artery aneurysm.

Ruptured aneurysms of the distal anterior choroidal artery (AchA) are extremely rare and management is dictated by clinical presentation. This report describes a rare patient with a distal AchA aneurysm and subarachnoid and intraventricular haemorrhage. A 60-year-old woman presented with a sudden onset of severe headache and vomiting. No aneurysms could be found on initial angiograms. A repeat angiogram performed 10 days after admission demonstrated an aneurysm in a branch of the cisternal segment of the left AchA without a definite neck. Surrounding vessels showed multifocal stricture and dilatation. Microsurgical clipping was not performed because the patient died suddenly due to pulmonary failure. The aetiology of the aneurysm in this case and surgical strategy are discussed.     

跻身红尘

一袭蓑衣，一根鱼竿，临岸静坐。庄子参破世间万物．宁愿静守一泓静水．坐看风云变幻． 一垄田．一把犁．茅屋菊花。陶渊明脱离浊淖，采菊东篱得见南山．行于世俗之外。

92例重型肝炎并发自发性细菌性腹膜炎的诊断与治疗

目的探讨重型肝炎并发自发性细菌性腹膜炎(SBP)的诊断和抗生素使用。方法回顾性分析2002年7月~2005年6月间收治的92例并发SBP的重型肝炎患者的临床资料。结果92例患者中,发热72例(78.26%),腹胀85例(92.39%),腹痛38例(41.30%),反跳痛35例(38.04%),83例(90.21%)外周血中性粒细胞(PMN)分类≥0.75,40例(45.98%)腹水PMN计数≥250个/mm3,79例(90.80%)腹水PMN比值≥0.50,11例(12.00%)腹水细菌培养阳性,共分离出细菌17株,G-杆菌占52.9%(9/17),其对头孢曲松、头孢哌酮、头孢他啶、左旋氧氟沙星及泰能敏感,对丁胺卡那、氧哌嗪青霉素敏感性较低。临床治疗显示,联合使用头孢他啶和甲硝唑效果较好,并较少出现继发真菌感染。结论重型肝炎并发SBP患者的临床表现不典型,腹水培养阳性率低,外周血和腹水PMN比值是诊断SBP比较可靠的参数。治疗SBP,可首选二联使用头孢他啶与甲硝唑,疗程约10~14日。
