慢性心力衰竭护理结局分类评价表的构建研究

目的本研究以护理结局分类(NOC)为基础,筛选符合慢性心力衰竭患者的相关护理结局,由此构建具有专科专病特点的慢性心力衰竭患者护理结局评价表。方法成立研究核心小组,应用文献回顾法、专家函询法确定护理结局分类指标,并进行统计学分析,最终建立慢性心力衰竭护理结局分类评价表。结果通过研究,确定慢性心力衰竭护理结局中包含4个领域、8个一级指标、68个二级指标。4个领域分别是生理健康、功能健康、健康知识和行为、心理社会健康。一级指标中包含心脏泵血功能、活动耐力、社会支持、抑郁水平等。二级指标中包含心脏指数、血压、呼吸困难、情绪波动大、步行距离、步行速度等68个指标。统计学分析中:第一、二轮函询专家的积极系数分别为90%、100%,专家权威系数为0.895,专家意见协调程度(P<0.05)。结论本研究成功建立慢性心力衰竭护理结局分类评价表,有助于临床护士用于评价护理措施的有效性,也使其成为一种标准化语言,便于应用到护理电子信息系统中进行绩效测算等。但是本研究不足之处是未能将该研究进行临床实证,未能进一步确认其有效性。     

结直肠癌化疗患者营养状况及营养治疗研究进展

结直肠癌是常见的消化道肿瘤，其营养不良发生率高且严重。化疗是结直肠癌常见治疗方式之一，并与营养不良独立相关，化疗后患营养不良风险增大且营养不良进一步加重。同时，营养不良可导致患者化疗疗效差及预后不良，并增加化疗相关不良反应、影响患者生活质量及降低生存率等。营养治疗能够有效改善患者营养状况，在肿瘤综合治疗中有重要作用，且多学科团队合作是有效的营养干预模式。目前营养治疗主要包括营养咨询、口服营养补充剂、肠内营养和肠外营养等，相关指南和研究表明在营养治疗时应首选口服营养补充剂及肠内营养，仅在采用以上治疗后仍存在营养不足或无法进行肠内营养时行肠外营养。本文主要对结直肠癌患者营养状况与化疗之间关系、营养治疗的最新研究进展及相关指南进行综述，以期引起临床上对结直肠癌化疗患者营养治疗方面重视并提供参考。

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.     

应用庆大霉素溶液与生理盐水行手外伤清创的效果比较

目的 探讨应用庆大霉素溶液与生理盐水对手外伤清创效果的差异。方法 对102例急诊手外伤患者，随机分为庆大霉素组（45例）和生理盐水组（57例）两组，分别由同一名医师进行常规清创，术后口服头孢氨苄胶囊预防感染5d，每3～4d伤口换药，观察伤口情况，于术后12d拆线，对伤口做出评价。结果 伤口愈合情况：庆大霉素组，甲级愈合20例，乙级愈合17例，丙级愈合8例；生理盐水组，甲级愈合24例，乙级愈合20例，雨级愈合13例。感染率：庆大霉素组17．78％，肥皂水组22．81％，平均为20．9％，两组比较差异无统计学意义（x^2=0．39，P〉0．05）。结论 使用庆大霉素溶液对伤口进行冲洗，并不能降低手外伤清创后的感染率。     

高转换型肾性骨病中骨保护素及其配体的表达和形态计量学观察

目的 观察高转换型肾性骨病中骨保护素及其配体 (OPG，RANKL)的表达，并与骨形态计量学指标进行相关分析。 方法 选择10例慢性肾衰尿毒症患者和3例正常人进行髂骨活检术，获得骨组织标本。采用免疫组化方法检测OPG和RANKL蛋白质的表达。采用全自动图像分析系统进行骨组织形态计量学测定。结果 10例慢性肾衰尿毒症患者经骨病理学检查证实均为高转换型骨病，以破骨细胞活化形成骨吸收陷窝伴或不伴骨矿化不全为特点。免疫组化显示尿毒症患者骨组织中以RANKL阳性表达为主。与正常对照相比，RANKL阳性表达细胞数目显著增加，OPG阳性表达细胞数目显著减少。尿毒症患者RANKL的阳性表达细胞数目与骨吸收面积和破骨细胞数目呈显著正相关。结论 高转换型肾性骨病中，PTH的溶骨作用可能是通过OPG/RANKL/RANK系统介导的。     

Modified superficial parotidectomy: preserving both the great auricular nerve and the parotid gland fascia.

OBJECTIVE: To reduce the incidence of sensory deficits and Frey's syndrome by modifying the traditional superficial parotidectomy. STUDY DESIGN: After raising the skin flap, the parotid gland fascia (PGF) was elevated to form a posterior pedicle fascial flap and then was replaced after the gland removal. The great auricular nerve (GAN) that runs within the PGF was not separated, so both the GAN and the PGF were preserved. Before this modification, the GAN and PGF were examined anatomically. The complication rates in the modified and control groups were compared. RESULTS: 1) The GAN, which runs within the thick and pycnotic PGF, trifurcates into postauricular, preauricular and lobule branches. The modification could be carried out practically based on the anatomy study. 2) Long-term sensory deficit was encountered in 13.3% of the control group, but 0% in the modified one. Frey's syndrome was suffered by 66.7% and 16.7% cases in the control and modified group respectively. The incidence of other complications was not significantly different. CONCLUSION: Our modification is practical. It decreases the complications significantly. EBM rating: B-3b.
