目前,冠状动脉造影已成为诊断冠心病,明确冠状动脉狭窄部位、程度的重要方法,对冠心病的诊断可达定量水平,为估计病人预后、决定药物使用及介入性治疗提供了更为确切的指标。由于介入性诊治属有创性,存在一定的风险,且术后需卧床制动,因此,绝大多数病人对该术存在担心恐惧等心理,加之术中、术后所承受的不适感觉,在很大程度上影响着该术的成功及病情变化,为减轻病人恐惧与担心,增加手术的成功率,认真做好病人的心理护理就显得尤为重要。自2000年6月我科开展冠状动脉介入性诊治护理以来,对病人心理特征不断进行观察分析,现将其总结如下。 相似文献

This is an unusual case presentation of a young woman with a clinical history and course simulating juvenile hyaline fibromatosis, but without hyalinization in the stroma. Because of the age of onset, the apparent familial inheritance, the nonaggressive and nonregressive tumor traits, the disease cannot be classified as multicentric fibromatosis. Therefore, we are referring to this case as multicentric fibromatosis with familial inheritance, a previously unreported entity to our knowledge. 相似文献

断肢断腕断掌再植后手内在肌挛缩51例分析 总被引:5,自引:1,他引:4
探讨断肢断腕断掌再植术后手内在肌挛缩的发病机理,结合临床经验提出分类、预防和治疗方法。方法:对51例断肢(腕、掌)再植,分别采用术中切开骨间肌肌筋膜、掌腱膜及腕横韧带;术后严重肿胀时早期切开骨筋膜室;缺血时间超过10小时者,除上述措施外尚须切断或部分切除拇收肌和骨间肌肌腹。结果:采用上述预防措施后,手内在肌挛缩的发生率明显降低。结论:本症重在预防,如能及时、果断地采取措施,效果良好。一旦发生中、重度手内在肌挛缩应尽早手术。 相似文献

本组12例骨肉瘤均采用动脉区域灌注灭活再植及术后化疗方法,术后2年存活率平均为75%,1例因经验不足致局部复发,仅占8.3%,表明在化疗保障下,采用此种方法即能保肢,又能获得与截肢治疗相同的手术效果,优于单纯行灭活再植术后中方法。 相似文献

关于单结合胆红素水溶性的研究 总被引:4,自引:0,他引:4
目的:进一步研究单结合胆红素(MCB)的水难溶特性及其在病理性胆汁中参与胆红素沉淀和色素性结石形成的作用机制.方法:应用胆红素高效液相色谱分析技术,先从人胆汁中获得结合胆红素,再经分离、制备及纯化得到纯MCB.然后观察其水溶解度并与其它型胆红素比较.结果:在pH7.9,温度37℃接近生理的条件下,MCB的溶解度(558.25±5.96μm)仅为双结合胆红素(DCB)的1/7,比不结合胆红素(UCB)高约44倍并随pH值改变而呈曲线变化.pH7.9时最大;pH4.5时为0;而当pH>9时,反而低于呈离于状态的UCB.结论:MCB虽作为结合型胆红素在胆道生理条件下的不溶性明显高于UCB,但比DCB要低得多;而在胆道病理条件下,其水溶性不但远低于DCB,甚至还不如离子化的UCB,这可能是MCB参与胆红素沉淀及胆色素结石形成的理化基础. 相似文献

CT造影剂碘海醇注射液的制备及动物实验 总被引:3,自引:0,他引:3
本文报道了非离子型X-CT造影剂碘海醇注射液的制备及动物实验结果。磺海醇的最大吸收波长λ_(max)为244nm。讨论了温度、浓度对磺海醇溶液粘度的影响:粘度随温度的升高而下降,呈负线型相关;粘度随浓度(C)升高而激剧升高,与浓度的四次方呈线性相关:V_(37℃)=472.589[C] ̄4+1.121(r=0.9977)V_(30℃)=663.813[C] ̄4+1.152(r=0.9996)V_(20℃)=1082.953[C] ̄4+1.433(r=0.9982)使用该注射液进行狗的造影实验,获得了清晰的造影图像。 相似文献

进一步重视脂肪新功能对创面愈合作用的研究 总被引:9,自引:1,他引:8
创面愈合的研究范围正随着相关领域的研究进展而不断拓展和完善。以皮下脂肪组织为例 ,以往多数的研究认为 ,脂肪组织来源于间充质细胞 (mesenchymalcell,MC) ,其功能仅是一个能量贮存仓库。但近年来的研究表明 ,脂肪组织还可能是一个重要的内分泌器官 ,在发育学、信号转导 ,以及干细胞作用等多方面与组织修复存在着密切联系。有专家认为 ,加强对脂肪细胞新功能的研究和开发 ,有可能对创面修复和组织再生机制产生新的认识 ,并寻找出新的促愈合手段。脂肪细胞参与创面愈合首先表现在它可能作为一个内分泌器官。迄今为止 ,已经发现人的脂肪细… 相似文献

测定72例健康老年人(60-84岁)和65例健康青中年人(20-50岁)血清和尿β2微球蛋白(β2m),发现前血清β2m浓度比后明显增高(p<0.001);老年组≥70岁尿液β2m浓度也明显增高(p<0.05)。结果表明肾小球滤过率下降随年龄增长而降低,以后再出现肾小管功能减退。本试验较血清尿素氮、肌酐和内生肌酐清除率测定更为敏感。 相似文献

There have been a few studies and inconsistent results regarding the coincidence of Parkinson's disease (PD) and atherosclerotic diseases, such as cerebrovascular disease. Carotid intima-media thickness (IMT) is a known marker for subclinical atherosclerosis. The aim of this study was to investigate the carotid IMT between PD patients and controls. We studied 43 patients with PD and 86 matched controls. The carotid IMT in PD patients was significantly smaller than in controls (0.796 +/- 0.179 mm vs. 0.913 +/- 0.237 mm, P < 0.05). In multivariate analysis, the carotid IMT was inversely associated with the duration of levodopa medication and the severity of PD. These results suggest that PD patients have a lower risk of atherosclerosis. 相似文献

Background: Elder patients with acute coronary syndromes (ACS) are less likely to receive cardiac catheterization. The reasons for this are unclear.
Objectives: To assess whether elder patients who had a documented history of dementia, lived in extended care facilities, or had do not intubate–do not resuscitate (DNR-DNI) advance directives were less likely to receive cardiac catheterization, despite having ACS with high-risk features.
Methods: This was a medical record review conducted at an urban teaching hospital. DNR-DNI status before hospitalization, extended care facility (nursing home or assisted living) residence, and a previous diagnosis of dementia were obtained from the medical record. Patients 65 years and older who presented to the emergency department with acute myocardial infarction or with unstable angina with ST segment deviation were included. Univariate and multivariate logistic regression were performed, and odds ratios (ORs) were reported with their 95% confidence intervals (CIs).
Results: Of the 201 eligible patients, 66 (32.8%) patients did not undergo cardiac catheterization. In the univariate analysis, patients who had dementia, resided in extended care facilities, or were DNR-DNI were less likely to receive cardiac catheterization. Only extended care facility residence (OR, 0.18; 95% CI = 0.04 to 0.83) and DNR-DNI status (OR, 0.19; 95% CI = 0.04 to 0.92) remained significantly associated with decreased cardiac catheterization in the multivariate analysis.
Conclusions: Elder patients with ACS residing in extended care facilities or who are DNR-DNI are less likely to receive cardiac catheterization. Future studies concerning the quality of ACS care for elders should take these variables into account. 相似文献
