外周血液中miRNA表达与老年性黄斑变性相关性研究

目的　检测微小核糖核酸（microribonucleicacids，miRNA）在老年性黄斑变性（age-related macular degeneration，AMD）患者中的表达，并探讨miRNA的表达量与AMD病程之间的关系。方法　选取2014年1月至2016年11月于同济大学附属第十人民医院眼科门诊就诊的AMD患者6例为试验组，并选取同期6名正常人为对照组，通过基因芯片技术检测两组血液中miRNA的表达量。扩大样本的病例对照研究中共纳入126例AMD患者和140名正常人，检测其血液样本中miRNA的表达，比较两组人群间miRNA的表达量差异。结果　通过基因芯片技术，在试验组与对照组间共检测出216个miRNA存在表达差异（均为P<0.05），与对照组相比，试验组中111个miRNA表达量上升，105个miRNA表达量下降，差异均有统计学意义（均为P<0.05）。扩大样本的病例对照研究结果表明，在AMD患者中，miR-27a-3p、miR-29b-3p、miR-195-5p的表达量显著上升，同时，湿性AMD患者血液中miR-27a-3p的表达量高于干性AMD患者，差异均有统计学意义（均为P<0.05）。结论　AMD患者外周血中miRNA表达量水平有明显变化，miR-27a-3p、miR-29b-3p、miR-195-5p可能成为AMD血清学诊断和预后的标志物。

使用棱镜重新定位双侧中心暗点患者视网膜物像的预试验

目的 本研究使用激光扫描检眼镜(SLO)评价双侧中央暗点患者使用棱镜后的眼球运动反应.方法 本预试验共招募6例有双侧中央暗点的年龄相关性黄斑变性(AMD)患者以及6例正常视力的志愿者.首先用Nidek MP-1微视野仪确认患者的中央暗点和优选视网膜注视点(PRL),然后用Rodenstock SLO,在将视标投射在优选视网膜注视点时拍下实时视网膜像,接着在受检者眼前加入6～8 PD的棱镜,要求受检者保持注视视标,这时通过视网膜标记来测量视网膜像的移位量,以及随后发生的优选视网膜注视点的再次注视.过程中平均移位量和再次注视时间通过图像软件(ImageJ software)来计算.结果 实验组再次注视时的移位量在3个像素点或11.66个弧分之内(x轴:2.90±3.92,y轴:2.53±4.18).对照组再次注视时的移位会准确些(x轴:0.33±1.15,y轴:0.89±2.50),但与实验组差异无统计学意义(tx=1.32,Px＞0.05;ty=0.80,Py＞0.05).对照组再次注视时间(0.98±0.19)s较实验组(2.83±1.63)s要短,差距有统计学意义(t=5.03,P＜0.01).其中有1例实验组受检者没有发生再次注视,其结果被排除并单独分析.结论 研究发现,双眼中央暗点患者对棱镜物像转移后的再注视反应与正常人接近,但实验组再注视明显较对照组慢,并有1例受检者没有发生再注视.该数据说明双侧中央暗点患者无论眼前有没有棱镜,都会利用相同的视网膜位置视物,因此,通过棱镜物像再定位的意义不大.     

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。     

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.     

腰椎融合术后邻近节段退变的诊断与治疗

目的：探讨腰椎融合术后邻近节段退变的特点及再手术治疗的术式与疗效.方法：回顾性分析2002年1月至2004年12月间收治的10例因腰椎管狭窄症或腰椎滑脱症曾行后路减压、植骨及椎弓根内固定术,术后12～132个月（平均41.6个月）出现新的腰腿痛症状的病例.对所有患者进行影像学检查,与术前资料比较,并行手术治疗.结果：X线片显示融合的上方（1个节段7例,2个节段1例）或下方（1个节段2例）邻近节段出现了退变,首次术前及术后上述邻近节段均未见退变征象.8例MRI显示邻近节段出现了新的椎管狭窄,且有明显的神经压迫.采用后路术式,将减压及固定融合范围向邻近退变节段延伸.经7～36个月平均12.1个月的随访,优良率80%.结论：腰椎融合术后邻近节段退变是术后症状复发的原因之一,应仔细鉴别症状复发的原因.对于有明显神经压迫者,再手术治疗仍可取得较好的疗效.     

腰椎终板、椎间盘退变及椎间盘造影疼痛激发试验的相关性研究

目的探讨下腰痛患者腰椎终板Modic退变、椎间盘退变及CT引导下腰椎间盘造影疼痛激发试验的相关性.方法对45例下腰痛患者常规行腰椎X线和MR检查,分别按Modic终板退变标准（0～3级）与Pearce椎间盘退变标准（Ⅰ～Ⅴ级）对终板和椎间盘进行评估.在CT引导下对45例患者中的40例（120个椎间盘）进行造影和疼痛激发试验,并按Dallas椎间盘造影分级系统（DDD）测评椎间盘退变程度.采用SPSS 11.5统计学软件分析腰椎终板Modic退变、椎间盘退变与腰椎间盘造影疼痛激发试验之间的相关性.结果40例下腰痛患者的腰椎终板Modic分级与椎间盘退变Pearce分级存在较强的相关性（Pearson x^2=43.326,P=0.000）,与椎间盘造影疼痛激发试验有显著相关性（Pearson x^2=27.858,P=0.000）;椎间盘退变Pearce分级与CT椎间盘造影椎间盘退变Dallas分级也呈较强的相关性.结论腰椎终板Modic退变分级与椎间盘退变Pearce分级密切相关,而与椎间盘疼痛激发试验有显著相关性,提示终板Modic退变可能是下腰痛的原因之一.
