①目的 探讨慢性阻塞性肺病(COPD)病人机械通气后下呼吸道感染致病菌的特点。②方法 取32例COPD并发呼吸衰竭行机械通气病人下呼吸道分泌物做痰细菌学培养，同时做药物敏感试验。③结果 32例病人共分离出菌株76株，阳性率71．7％，其中混合感染10例次。其中革兰阴性杆菌(GNB)58株，占76．3％；阳性球菌10株，占13．2％；真菌8株，占10．5％。常见致病菌以铜绿假单胞菌、鲍曼不动杆菌和肺炎杆菌为主，GNB中铜绿假单胞菌和不动杆菌的耐药率高。④结论 COPD应用机械通气病人下呼吸道感染以革兰阴性杆菌为主，耐药性高。     

冠状动脉造影病人的心理问题及护理

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。     

关于单结合胆红素水溶性的研究

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.     

SARS流行期间肺炎患者的临床表现和胸部影像变化的探讨

目的 探讨SARS流行期间肺炎患者的临床表现和胸部影像变化特点。方法 对76例SARS流行期间发热留观室收治的肺炎患者的临床表现及胸部影像进行分析。结果 (1)此组肺炎患者多为青壮年(占60．53％)，无固定职业或职业性质流动性较大者居多(69．74％)；(2)临床特征主要是发热，以中高热为多见(80．26％)，发病早期部分患者呼吸道症状并不明显(67．10％)，外周血WBC在正常或低于正常范围(85．53％)，淋巴细胞比例减少(75．00％)；(3)肺部CT表现为不同程度的炎性浸润；病灶形态以斑片状和球形多见(77．63％)；病灶常位于肺周边，常出现支气管气像；动态观察病变影像大多无明显进展(88．16％％)，经治疗均完全吸收。结论 SARS流行期间普通肺炎与非典型肺炎有相似的临床及胸部影像表现；肺部CT扫描能早期发现肺炎患者的异常阴影，明显优于胸片，但无特异性。因此，在SARS流行期间发热诊室医务人员应加强肺部炎性改变的早期诊断和鉴别诊断水平。     

咀嚼槟榔习惯与牙体磨损关系的临床研究

目的 :探讨长期咀嚼槟榔与牙体磨损的关系。方法 :对长期咀嚼槟榔的 6 4例患者的咀嚼槟榔时间、频率及其牙体牙合面磨损、曲面体层片进行分析。结果 :所有患者后牙牙合面出现不同程度的磨损 ,且咀嚼槟榔时间越长 ,牙合面磨损越严重 (P <0 .0 1) ;咀嚼频率越高 ,牙合面磨损加重 (P <0 .0 1) ,磨损严重者可伴根尖周炎症及牙槽骨不同程度吸收。结论 :长期咀嚼槟榔可导致牙体牙合面不同程度磨损。     

Carotid intima-media thickness in Parkinson's disease.

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.     

Factors Affecting Cardiac Catheterization Rates in Elders with Acute Coronary Syndromes

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.
