Pick’s disease with Pick bodies combined with progressive supranuclear palsy without tuft‐shaped astrocytes: A clinical,neuroradiologic and pathological study of an autopsied case

We report clinical, neuroradiologic features, and neuropathologic findings of a 76‐year‐old man with coexistent Pick’s disease and progressive supranuclear palsy. The patient presented with loss of recent memory, abnormal behavior and change in personality at the age of 60. The symptoms were progressive. Three years later, repetitive or compulsive behavior became prominent. About 9 years after onset, he had difficulty moving and became bed‐ridden because of a fracture of his left leg. His condition gradually deteriorated and he developed mutism and became vegetative. The patient died from pneumonia 16 years after the onset of symptoms. Serial MRI scans showed progressive cortex atrophy, especially in the bilateral frontal and temporal lobes. Macroscopic inspection showed severe atrophy of the whole brain, including cerebrum, brainstem and cerebellum. Microscopic observations showed extensive superficial spongiosis and severe neuronal loss with gliosis in the second and third cortical layers in the frontal, temporal and parietal cortex. There were Pick cells and argyrophilic Pick bodies, which were tau‐ and ubiquitin‐positive in neurons of layers II–III of the above‐mentioned cortex. Numerous argyrophilic Pick bodies were observed in the hippocampus, especially in the dentate fascia. In addition, moderate to severe loss of neurons was found with gliosis and a lot of Gallyas/tau‐positive globus neurofibrillary tangles in the caudate nucleus, globus pallidus, thalamus, substantia nigra, locus coeruleus and dentate nucleus. Numerous thorned‐astrocytes and coiled bodies but no‐tuft shaped astrocytes were noted in the basal ganglion, brainstem and cerebellar white matter. In conclusion, these histopathological features were compatible with classical Pick’s disease and coexistence with progressive supranuclear palsy without tuft‐shaped astrocytes.     

儿童肺炎支原体感染状况分析

目的 探讨儿童的肺炎支原体(MP)感染现状及早期诊断的意义。方法 检测181例就诊儿童血液标本分析MP感染的状况。结果 肺炎支原体感染率为29.8％;男性患儿MP检测阳性率(35.7％)明显高于女性患儿(16.4％)(P<0.01);5岁以下患儿阳性率超过50％,且有3例婴儿检测阳性;10-12月份支原体肺炎发病率明显增加,占全年的40.7％。结论 针对儿童支原体肺炎的发病情况,早诊断,早治疗,利于患儿尽早康复,防止肺部病变迁延及肺外并发症的发生。     

30例原位肝移植手术临床分析

目的总结原位肝移植手术的临床经验,探讨提高肝移植手术效果的措施。方法回顾分析2003年12月~2006年3月30例原位肝移植患者的临床资料,均采用同种异体(尸体供肝)原位全肝移植,其中经典式24例,背驮式6例。结果30例手术全部成功,供肝热缺血时间平均4.5 m in,冷缺血时间5 h。围术期死亡3例。与手术相关主要并发症有:腹腔内出血4例,门静脉狭窄2例,胆道吻合口狭窄1例、胰漏1例、胸腔积液5例。27例获随访3~30个月,1例术后3月死于胆道铸型综合征并感染,肝癌复发2例。结论确保供肝质量是肝移植成功的前提,良好的血管和胆管重建技术是肝移植手术成功的关键,专业化的围手术期处理可有效地减少并发症的发生。

代孕技术中的伦理道德及法律问题

新近发展的代孕技术给众多不孕夫妇带来为人父母的喜悦之时,也对人们传统的生殖伦理观念形成冲击并挑战现存法律制度.人们不仅要肯定代孕技术的合理性,也要警惕其所产生的潜在的破坏性影响.合理利用该技术和制定相应的法规是避免出现伦理和社会混乱的有效途径.     

膝关节运动过程的应力数值模拟

目的观察膝关节关节面在整个运动过程中的应力、应变分布范围、大小及变化规律。方法利用有限元数值模拟方法对行走过程中膝关节关节面应力、应变情况进行分析。结果与结论行走过程中关节面产生应力、应变随时间推移而增加，并且变化规律近似的服从抛物线变化。通过对不同体重的人在行走时膝关节面上产生的应力分析得出，体重对关节面上的应力的大小并不产生重大影响，体重带来的应力差异仅占总应力的10％。     

神经导航系统在神经外科显微手术中的应用

目的探讨神经导航系统在神经外科显微手术中的应用价值。方法我科在2004年10月至2005年6月应用美国Stryker神经导航系统辅助进行显微神经外科手术治疗颅内病变104例。结果在85例病灶切除术中,病灶全切除71例(83．53%),次全切除13例(15．29%),部分切除1例(1．18$)；侧脑室-腹腔分流术16例,成功15例,1例改常规手术完成；3例脑脓肿穿刺成功率100%。本组术后死亡1例,其余术后恢复良好。104例平均注册误差(1．3±0．7)mm。结论神经导航系统在神经外科手术中提供术中动态跟踪、实时导航,准确、直观,有助于提高手术疗效,降低手术并发症的发生。     

Measurement of alveolar derecruitment in patients with acute lung injury: computerized tomography versus pressure–volume curve

Introduction  

Positive end-expiratory pressure (PEEP)-induced lung derecruitment can be assessed by a pressure–volume (P–V) curve method or by lung computed tomography (CT). However, only the first method can be used at the bedside. The aim of the study was to compare both methods for assessing alveolar derecruitment after the removal of PEEP in patients with acute lung injury or acute respiratory distress syndrome.
