糖尿病合并肺炎患者支气管肺泡灌洗液细胞学分析

目的评价糖尿病合并肺炎病人抗生素治疗2周后支气管肺泡灌洗液(bronchoalveolar lavage fluid,BALF)中细胞学成分的特点,并与非糖尿病的肺炎病人进行比较,了解病灶局部炎症反应及吸收与非糖尿病组有否区别。方法抗生素治疗2周行支气管肺泡灌洗,测定BALF中细胞数、分类及淋巴细胞亚群。复查胸部X光片,对比两组之间BALF中细胞成分及肺部阴影完全吸收占病人的百分比。结果抗炎治疗2周后,糖尿病合并肺炎病人虽然外周血WBC已经恢复正常,但BALF中中性粒细胞的比率明显高于非糖尿病肺炎组(分别为54.89±11.23;27.02±6.95,P<0.05),且淋巴细胞亚群中CD4、CD4/CD8(分别为20.69±5.56;65%)。也较非糖尿病肺炎病人低(43.22±11.03;96%,P<0.01),治疗2周后,非糖尿病肺炎组肺部阴影吸收率为68%,糖尿病合并肺炎组为43.5%(P>0.05)。结论抗生素治疗2周后糖尿病合并肺炎组肺部局部炎症反应仍然存在,肺部阴影有延迟吸收倾向。     

Zum Einfluß von Operationszeitpunkt und Kliniksorganisation auf die postoperativen Komplikationen

Zusammenfassung Über ein Jahr wurden 1082 allgemeinchirurgische Planeingriffe prospektiv konsekutiv erfaßt und ihre Komplikationen mit einem Score bewertet. EinflußgröBen und die Komplikationsraten, die unter Umständen von der Kliniks-organisation abhängig sind, sollten analysiert werden. Es fand sich eine Beziehung zwischen Komplikationen und Wochentag, Operationsdauer sowie der Abweichung der tatsächlich benötigten von der geplanten Operationszeit. Mit höherer Auslastung der Operationssäle pro Arbeitstag stiegen die Komplikationsraten ebenfalls an.Keinen Einfluß auf die Komplikationsraten hatten Operationsbeginn und-monat sowie die monatliche Auslastung der Säle. Ob das Wetter einen Einfluß auf die Komplikationsraten nahm, konnte nicht entschieden werden: so fanden sich im Sommer- höhere Komplikationsraten als im Winterhalbjahr, jedoch war der Score von der Höhe der Außentemperatur und der Luftfeuchtigkeit unabhängig.

The influence of time of operation and hospital organization on postoperative complication rates

Summary During a 1-year period 1082 general surgical interventions were prospectively documented and their complication rates evaluated by a score system. Factors responsible for the complication rates and possibly depending on hospital organization should be analysed. The complication rates were influenced by the selection of the weekday, the length of operation time and the extent of discrepancy between planned and required operation time. Furthermore, the complication rates paralleled the extent of utilization of the operation theatre during a workday. The complication rates werenot affected by the beginning of operation and the operation month as well as the monthly utilization of the operation theatres. Whether the weather did influence the complication rates could not be decided: higher complication rates were found in the summer as compared to the winter period, but the complication score was independent of the level of the outside temperature and humidity.

     

支原体肺炎肺外损伤患儿T细胞亚群、IFNγ、TNFα的变化及意义

目的 探讨支原体肺炎肺外损伤患儿细胞免疫、细胞因子状况和胸腺肽的治疗效果。方法 采用流式细胞仪和酶标仪检测31例支原体肺炎肺外损伤组患儿急性期、恢复期血中CD3CD4、CD8、CD4／CD8干扰素γ（IFNγ）、肿瘤坏死因子α（TNFα水平，并与支原体肺炎组比较。结果 ①急性期支原体肺炎肺外损伤组和支原体肺炎组比较，CD3、CD4显著降低（P〈0．05），TNFα显著升高（P〈0．01），CD8、IFNγ无统计学意义（P〉0．05）；②支原体肺炎肺外损伤组急性期和4周后比较，CD3、CD4、IFNγ升高（P〈0．05），TNFα显著降低（P〈0．01），CD8无变化。用胸腺肽治疗患者以上指标变化更明显。结论 支原体肺炎肺外损伤患儿细胞免疫功能低于支原体肺炎患儿；细胞因子中TNFα早期升高，而IFNγ不明显；恢复期TNFα下降，而IFNγ升高明显。用胸腺肽治疗能缩短病程。     

Prognostic factors for early clinical failure in patients with severe community-acquired pneumonia

For patients with community-acquired pneumonia (CAP), clinical response during the first days of treatment is predictive of clinical outcome. As risk assessments can improve the efficiency of pneumonia management, a prospective cohort study to assess clinical, biochemical and microbiological predictors of early clinical failure was conducted in patients with severe CAP (pneumonia severity index score of >90 or according to the American Thoracic Society definition). Failure was assessed at day 3 and was defined as death, a need for mechanical ventilation, respiratory rate >25/min, PaO2 <55 mm Hg, oxygen saturation <90%, haemodynamic instability, temperature >38 degrees C or confusion. Of 260 patients, 80 (31%) had early clinical failure, associated mainly with a respiratory rate >25/minute (n = 34), oxygen saturation <90% (n = 28) and confusion (n = 20). In multivariate logistic regression analysis, failure was associated independently with altered mental state (OR 3.19, 95% CI 1.75-5.80), arterial PaH <7.35 mm Hg (OR 4.29, 95% CI 1.53-12.05) and PaO2 <60 mm Hg (OR 1.75, 95% CI 0.97-3.15). A history of heart failure was associated inversely with clinical failure (OR 0.30, 95% CI 0.10-0.96). Patients who failed to respond had a higher 28-day mortality rate and a longer hospital stay. It was concluded that routine clinical and biochemical information can be used to predict early clinical failure in patients with severe CAP.     

A novel mutation in the last exon of ATRX in a patient with α-thalassemia myelodysplastic syndrome

Abstract:  We describe a patient with acquired alpha-thalassemia myelodysplastic syndrome (ATMDS). A previously healthy 66-year-old man presented with hemoglobin of 9.3 g/dL, mean corpuscular volume 59 fL, and a bone marrow aspirate with increased erythroid precursors and hypolobulated megakaryocytes. Hemoglobin H inclusions were seen in most red cells after 1% brilliant cresyl blue supravital stain of the peripheral blood. At the molecular level, we identified of a novel mutation in the most 3' exon of the ATRX gene ( C GA→ T GA substitution in codon 2407) resulting in a premature termination codon (p.R2407X). This case provides further evidence for a link between ATRX mutations and ATMDS, and suggests a possible role for the conserved Q-box element in ATRX function.     

岗位业绩导向的医院薪酬设计

基于现代管理理论和医院的实际情况，设计了一种以岗位和业绩为导向的医院薪酬制度。该设计的主要特点是：①薪酬结构以岗位工资和绩效工资为主体，同时兼顾稳定和逐步过渡原则，原档案工资的固定部分(约占档案工资的60％)保留。②岗位工资采用全院统一的等级薪酬结构，等级的评定基于全院统一的指标体系和权重，岗位工资每年随绩效考核结果在工资带宽中升降；③绩效工资与岗位等级和绩效考核紧密挂钩，考核的依据是全院统一模式的岗位绩效合同；④整个薪酬设计建立在岗位调查、岗位评价和岗位说明书等的科学规范的工作基础之上。     

SARS与细菌性典型肺炎的胸部CT特征对比分析

目的：探讨重症急性呼吸综合征(SARS)与细菌性典型肺炎胸部CT特征的异同．方法：回顾性分析28例SARS胸部CT表现与细菌性典型肺炎做对比结果：本组28例患者肺部病变初期多为单发病灶，在右侧外带胸膜下常见。片状磨玻璃样密度病变影存在于各期，而细菌性典型肺炎未见、发病初期和进展期肺容积变小?而细菌性典型肺炎多无此特点。进展期大多数发展为双肺由下至上痛变、恢复期病变由最晚受侵部位消退，遗留纤维化多为最早发生病变部位?而典型肺炎多从近肺门侧开始吸收，进展期局限的肺段、肺叶发展至多个肺叶、肺段，进展较迅速。而细菌性典型肺炎多为单独的肺叶、肺段．恢复期由弥漫性多发病变转变为局限病变，部分病人有肺部纤维化发生，而细菌性典型肺炎大多数吸收较完全，不遗留肺纤维化。结论：SARS所存在的急性间质性肺炎和急性肺炎可利用CT动态检查较准确地与细菌性典型肺炙加以区别。
