经肺动脉与支气管动脉血管造影的CTA观察原发肺癌的血供

目的用支气管动脉(BA)和肺动脉(PA)造影CTA观察肺癌血供情况。方法前瞻性观察6例支气管肺癌患者,分别行体循环动脉和肺动脉数字减影血管造影(DSA)后,留置BA导管与PA导管行CTBA与CTPA,观察BA与PA对肺癌的血供。结果CTPA上,无体动脉与左心强化的图像上肿瘤未见强化,有体动脉或左心强化的图像上见肿瘤边缘强化,CT强化值为10.0~45.6 Hu。CTBA上肿瘤部分明显强化,CT强化值为150.3~320.7 Hu,可见杂乱无章的肿瘤血管影,3例见纵隔淋巴结强化。结论本组病例观察表明原发性肺癌由BA为主的多发体循环动脉供血,未发现PA参与供血。

胰胆管合流异常动物模型的建立

目的建立胰胆管合流异常的动物模型。方法选用健康杂种猫10只。术前禁食12 h,3.5%戊巴比妥钠麻醉后,取上腹正中切口约6 cm切开各层至腹腔。于胆总管入十二指肠处旁边,切开胰腺背膜,解剖胰管;靠近十二指肠处分别纵向切开胰管、胆管长约4~6 mm的切口。6-0线间断吻合切口,造成类似人类的胰胆管合流的共同通道。术后20天胆道造影。结果术后动物精神、食欲良好,无萎靡、烦燥等表现,造影显示胰胆管合流共同通道延长。结论本动物模型最接近于人类的胰胆管合流异常生理,优于其他动物模型。     

谷氨酰胺在危重病患者中的应用

目的探讨危重病患者中早期经静脉应用谷氨酰胺（glutamine，Gl）的临床价值。方法42例患者随机分成两组（对照组和Gln组），Gln组进行Gln治疗（100mL／d，共7d）。治疗前后检测患者体质量、白蛋白、谷胱甘肽（GSH）、握力的变化和肠功能不全的发生率。结果体质量两组治疗前后比较差异无显著性（P〉0．05）。白蛋白、握力和GSH Gl治疗后非常显著高于治疗前（P〈0．01）；白蛋白对照组治疗后较治疗前显著增高（P〈0．05），但握力和GSH治疗前后均无显著变化（P〉0.05）；肠功能不全的发生率Gln组为4．8％，显著低于对照组（28．6％，P〈0．05）。结论在危重病患者疾病早期通过静脉途径外源性地补充Gln，有效改善了患者的营养状况；使患者血浆中的GSH水平增高，加强了机体的抗氧化能力；减少了患者肠功能不全的发生率。     

对血吸虫病患者心理护理问题的思考

长期以来,对血吸虫病患者心理护理方面重视不够。鉴于此,根据湖北省孝感市血吸虫病防治所2003~2004年收治的251例血吸虫病患者的心理状况观察资料,浅谈对不同病型血吸虫病患者心理护理的对策。1不同类型血吸虫病患者的心理特点1.1急性血吸虫病这类患者以新感染者为主。患者对血吸虫病比较陌生,医护人员及家属一举一动直接影响其心理活动。具体表现为:情绪紧张,对该病不了解,经常找医生打听病情,担心病情过重难以医治,因而造成失眠纳差,情绪不安,植物神经功能紊乱等。1.2慢性血吸虫病这类患者多数是疫区20~50岁的青壮年,均为家庭的主要劳动力…     

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.     

Irritable bowel syndrome and health-related quality of life: a population-based study in Calgary, Alberta.

BACKGROUND: Little is known about the health-related quality of life (HRQOL) of nonclinical samples of people with irritable bowel syndrome (IBS) in Canada. In a pilot survey, the impact of IBS on HRQOL using a population-based, urban sample was examined. METHODS: A random sample of Calgary residents (18 years of age or older), selected by random digit dialing (n=1521), completed a structured questionnaire including ROME II Criteria and Medical Outcomes Study Short-Form 12-Item Health Survey, version 2 (SF-12v2). The mean scale and summary scores of SF-12v2 for those who did and did not meet ROME II criteria and for those who met ROME II criteria with and without visiting a physician in past three months were determined and compared using multiple regression analyses. RESULTS: Of the 951 households successfully contacted, 590 (62%) were willing to participate, of which 437 (74%) individuals were recruited. One hundred ten IBS cases (81 of which were women) and 327 non-IBS controls (180 of which were women) were identified. All of the eight mean scale scores and the two mean summary scores were significantly lower in people with IBS than in those without, whether or not adjusting for demographics. Forty-four of the 110 IBS cases (40%) sought medical help. Significantly lower mean physical component score and three scale scores (general health, social functioning and role physical) were found in those who sought medical help than in those who did not. CONCLUSIONS: People with IBS experience significant impairment in HRQOL, including both physical and mental well-being. People with IBS who seek medical help report worse physical health than those who do not, but their mental health is no different.
