随着我国人民生活水平的不断提高,脂肪肝在人群中患病率也呈逐步上升的趋势.为此,笔者收集我院1999～2004年入院保健疗养飞行人员体检资料,就脂肪肝在不同机种飞行人员中的患病率分析如下.     

脊椎转移瘤增强减影MR成像

目的评估增强减影在脊椎转移瘤MR I中的应用价值。方法50例脊椎转移瘤病人进行MR I增强扫描,对比剂采用Gd-DTPA(0.1 mmol/kg),然后用T1W I增强后的图像与增强前的图像进行减影。通过对比噪声比(CNR)、信噪比(SNR)以及肿瘤边界清晰程度的比较,对MR I减影与否进行评估。结果MR I对比增强减影图像比传统的T1W I增强图像显示更清晰、更直观。所有脊椎转移瘤图像MR I减影的CNR和SNR比常规T1W I增强图像的CNR和SNR高。MR I减影CNR为155.05±24.73(x±SD),常规T1W I增强图像的CNR为11.11±14.26(t=35.65,Ρ<0.001)。MR I减影SNR为192.82±32.89(x±SD),常规T1W I增强图像的SNR为46.03±28.22(t=23.95,Ρ<0.001))。MR I对比增强减影图像比传统的T1W I增强图像能更好地显示脊椎转移瘤的边界和侵犯情况(2χ=29.34,Ρ<0.005)。结论MR I增强减影为探查和评估脊椎转移瘤提供了一个新的诊断方法。     

血小板计数在中晚期肝硬化诊断中的价值

目的探讨血小板计数在肝硬化方面的诊断价值。方法对本院门诊及住院病人,经确诊的肝硬化患者排除MVC小于80fl病例后分为中、晚期二组进行血小板计数统计并作统计学处理。结果中期肝硬化ALP计数为(143±36)×109/L,低于对照组(181±45)×109/L(p<0·01)。晚期肝硬化组ALP计数(86±28)×109/L,明显低于对照组(p<0·01),有非常显著性差异。结论晚期肝硬化患者血小板计数明显低于正常对照组,建议血小板计数可作为晚期肝硬化的诊断指标之一。     

渐进性活动训练预防膀胱全切、尿流改道术后患者小肠梗阻的对照研究

目的研究渐进性活动训练对膀胱全切、尿流改道术后患者肠功能恢复的影响.方法2003年1月～2005年8月,将138例行膀胱全切、尿流改道术的患者随机分为2组,训练组在常规护理方法的基础上,同时实施渐进性活动训练,对照组采取常规护理方法.结果2组患者小肠梗阻的发生比较,差异有显著意义(P＜0.01).结论渐进性活动训练可降低膀胱全切、尿流改道术后患者小肠梗阻的发生.     

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.

老年恶性肿瘤患者伴发抑郁状态的调查及分析

目的:了解老年恶性肿瘤患者抑郁状态的发生情况及相关危险因素。方法:采用抑郁自评量表(SDS)对48例住院的老年恶性肿瘤患者进行调查,并进行卫生统计学分析。结果:该组48例调查对象抑郁状态的发生率为41·7%(20/48)。女性,疾病进展,接受姑息治疗,放疗,化疗及疾病本身所致不适症状,经济压力大与抑郁状态密切相关。本组抑郁状态主要表现为情绪低落,纳差,体重变化,失眠,疲乏。结论:老年恶性肿瘤患者伴发抑郁状态发生率高,值得重视。在治疗、护理躯体疾病的同时应给予心理支持,以提高患者的生存质量。
