神经电生理对腓总神经卡压的诊断价值

目的 观察神经电生理检测对腓总神经卡压的诊断价值。方法 对腓总神经卡压的临床特征及病因进行分析，并作神经传导速度和肌电图检测和分析。结果 21条患病神经中1条神经波形消失。其余有不同程度的传导速度减慢，尤其是跨腓骨小头段，波幅降低，传导时间延长，42块腓总神经支配的肌肉中有30块出现失神经电位。结论 神经电生理检查在腓总神经卡压的诊断中有重要意义。     

妇科门诊子宫颈病变常识问卷调查

目的了解我院门诊就诊者对子宫颈病变相关知识的认识。方法自制问卷调查表，采用无记名，当面问卷调查方式。结果从调查100例就诊者中，未做过健康体检、妇科盆腔检查和宫颈刮片检查分别为34例、24例和52例。对宫颈癌的认识不知道者53例。结论建议相关部门加强对妇女的健康教育，提高其健康意识，强化临床医生的防癌意识和对子宫病变的规范化诊治。     

下颈椎可屈性与寰枢关节Magerl固定术的可行性分析

目的:探讨下颈椎的屈曲程度与后路经寰枢关节螺钉固定术的可能性。方法:回顾已施行经寰枢关节螺钉固定术病例的术前颈椎过屈位X线像,测量C2～C7间的角度,复习手术经过,分析可完成螺钉固定的颈椎曲度及其它相关因素。结果:在已完成后路经寰枢关节螺钉固定术的75例患者中有58例屈颈侧位X线像显示下颈椎呈后凸状态,后凸角平均为17.25°;另17例屈颈侧位片见下颈椎呈前凸状态,但这些病例都是体形瘦长者。结论:后路经寰枢关节螺钉固定术仅适合于下颈椎可以很好屈曲及体形瘦长的病例。     

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.

噬菌体基因组PaP1的鸟枪法测序及其生物信息学分析

目的对分离的铜绿假单胞菌噬菌体PaP1进行全基因组测序，并进行初步的生物信息学分析，为噬菌体的改造及其治疗奠定基础。方法采用鸟枪法随机测序和重叠群组装的策略对PaP1进行基因组测序，并通过EditSeq、开放读码框架（ORF）finder、GeneMark^TM、BPROM、FindTerm、Palindromes、Equicktandem及FAStRNA等软件对所获得的基因组序列的一般特征、蛋白质同源性序列及tRNA基因等进行分析和预测。结果PaP1基因组约为90000bp，其中最大重叠群为28249bp。在已获得序列中预测出120个ORFs、41个推定基因及9个簇集在5’末端的tRNA基因。在41个推定基因中，预测出编码DNA末端酶大亚单位、DNA解旋酶B亚单位、肽聚糖结合蛋白及3个尾丝蛋白等6个基因的功能。结论鸟枪法只能测出噬菌体基因组PaP1的部分序列，重复序列的存在是该基因组测序困难的原因。
