Soluble triggering receptor expressed on myeloid cells-1 in acute respiratory infections.

Levels of the soluble form of the triggering receptor expressed on myeloid cells (sTREM)-1 are elevated in severe sepsis. However, it is not known whether sTREM-1 measurements can distinguish milder bacterial infections from noninfectious inflammation. The present authors studied whether serum sTREM-1 levels differ in community-acquired pneumonia, exacerbations of chronic obstructive pulmonary disease (COPD), asthma and controls, and whether sTREM-1 may be used as a surrogate marker for the need for antibiotics. Serum sTREM-1 levels in 150 patients with pneumonia, COPD and asthma exacerbations and 62 healthy controls were measured. Serum sTREM-1 levels were significantly elevated in pneumonia (median 295.2 ng x mL(-1)), COPD (280.3 ng x mL(-1)) and asthma exacerbations (184.0 ng x mL(-1)) compared with controls (83.1 ng x mL(-1)). Levels were higher in pneumonia and Anthonisen type 1 COPD exacerbations than in type 2 and 3 COPD and asthma exacerbations. The area under the receiver operating characteristics curve for sTREM-1 as a surrogate marker for the need for antibiotics was 0.77. Serum levels of the soluble form of the triggering receptor expressed on myeloid cells-1 were elevated predominantly in pneumonia and Anthonisen type 1 COPD exacerbations versus type 2 and 3 chronic obstructive pulmonary disease exacerbations, asthma and controls. Serum levels of the soluble form of the triggering receptor expressed on myeloid cells-1 has moderate but insufficient accuracy as a surrogate marker for the need for antibiotics in lower respiratory tract infections.

培养护生养成阅读药物说明书的习惯

同类药物因原料来源、附加成分和生产厂家不同而商品名称各异，有些名称相似的药物其性能却完全不同。临床实习护生常反映课本讲授的药物知识与临床用药相差甚远，不知如何记住所有的药物。为此，作者在临床教学中培养学生养成阅读药物说明书的习惯，收到良好效果。     

Body weight and comorbidity predict mortality in COPD patients treated with oxygen therapy.

The aim of this study was to investigate the association between clinical variables and all-cause and respiratory mortality in patients with chronic obstructive pulmonary disease (COPD) undergoing long-term oxygen therapy (LTOT). The authors retrospectively studied a historic cohort of 128 patients with COPD (126 males, mean age+/-SD 68.9+/-9.7 yrs, body mass index (BMI) 25.1+/-4.5 kg.m-2, and forced expiratory volume in one second 25.4+/-8.8% predicted), who were being treated with long-term oxygen therapy in a tertiary teaching hospital between 1992 and 1999. Comorbidity, assessed with the Charlson Index, was present in 38% of the patients. Vital status and cause of death were assessed through the population death registry. A total of 78 patients (61%) had died by the end of follow-up. Three-year survival was 55%. Death was due to respiratory causes in 77% of cases. On Cox analysis, BMI<25 kg.m-2, comorbid conditions, age>or=70 yrs and cor pulmonale were associated with all-cause mortality. The BMI and comorbidity were the only significant predictive factors when the analysis was restricted to respiratory mortality. In conclusion, body mass index<25 kg.m-2 and comorbidity were predictors of all-cause and respiratory mortality in a cohort of chronic obstructive pulmonary disease patients treated with long-term oxygen therapy. These factors should be taken into account when considering the management and prognosis of these patients.     

氯氮平、氟哌啶醇和氯丙嗪对慢性精神分裂症患者糖、脂代谢及体质量的影响

目的 探讨氯氮平、氟哌啶醇和氯丙嗪对慢性精神分裂症患者的糖、脂代谢和体质量的影响。方法 对服用氯氮平（89例，氯氮平组），服用氟哌啶醇（87例，氟哌啶醇组）及服用氯丙嗪（83例，氯丙嗪组）治疗的慢性精神分裂症患者于治疗前后的不同时间进行血糖、胰岛素、血脂及体质量测定，并做相关因素分析。结果 氯氮平组治疗第90天和第180天空腹血糖异常（空腹血浆血糖〉7.0mmo/L）的发生率分别为8％及24％，氟哌啶醇组分别为1％和2％，氯丙嗪组分别为1％及4％。治疗第90天氯氮平组和氯丙嗪组的空腹及餐后2h血糖浓度均较治疗前升高，治疗第180天的血糖浓度高于第90天，氟哌啶醇组各时点的变化则不明显；差异均有统计学意义（P均〈0．01）。治疗第90天，氯氮平组的体质量平均高于治疗前5．5％，氯丙嗪组高于治疗前4．8％；治疗第180天两组分别高于治疗前9．1％和7．4％；氟哌啶醇组则无明显变化；三组间的差异有统计学意义（P〈0．01）。三组患者治疗第180天的胰岛素浓度均高于治疗前，差异均有统计学意义（P均〈0．01），但三组间的差异无统计学意义（P〉0．05）。氯氮平组和氯丙嗪组的胆固醇和甘油三酯浓度均高于治疗前，差异均有统计学意义（P均〈0．01），氟哌啶醇组则无明显变化。治疗第180天氯氮平组和氯丙嗪组患者血糖、胰岛素、血脂浓度与体质量均有一定相关性（r=0．23-0．39）；氯氮平组的血糖、体质量、血脂代谢还与血药浓度呈显著性相关（r=0．28-0．62），差异均有统计学意义（P〈0．05或〈0．01）。结论 氯氮平和氯丙嗪治疗影响慢性精神分裂症患者的糖、脂代谢及体质量。
