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.     

微板紫外速率法漏检高值ALT标本一例

谷丙氨基转移酶（Alanine asninotrasferase，ALT）检测是采供血机构血液必检项目之一，ALT检测作为早期肝病诊断的一项非特异性指标，有助于鉴别与输血相关肝炎病毒携带者，同时可以在一定程度上弥补某些肝炎病毒标志物未被检测及“窗口期”的缺陷，有助于预防输血相关肝炎的传播。我血站实验室采用微板为载体的方法进行血清ALT检测：微板紫外速率法为初检方法；微板丙酮酸氧化酶法为复检方法。在检测过程中一例高值ALT血样，微板紫外速率法检测结果为6．6U／L，出现假阴性结果造成漏检，现报告如下：     

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.     

双水平气道正压无创通气用于老年患者全麻恢复期的呼吸支持

目的研究双水平气道正压(BiPAP)通气在老年患者全麻恢复期呼吸支持的可行性。方法30例择期手术的老年患者随机分为BiPAP组与对照组,每组15例。在术前、拔管后、吸氧或无创通气1h后三个时点比较血液动力学、动脉血气分析参数和呼吸动力学指标。结果两组患者血液动力学的各项指标在各时点差异无显著意义;BiPAP组无创通气1h后PaCO2较拔管后降低,与对照组吸氧1h后比PaCO2低;拔管后两组患者PaO2较术前降低,BiPAP组吸氧1h可提高PaO2。BiPAP无创通气1h后,VTi、VE、Cdyn升高,RAWm降低;而对照组吸氧1h后较拔管后无明显改善。结论老年患者短期BiPAP面罩支持无创通气耐受性好,对血液动力学无明显影响,可以改善通气和氧合,降低气道阻力,提高肺顺应性。     

CYP17基因新的突变导致两姐妹17α羟化酶/17,20裂链酶联合缺乏

目的分析一家庭中患17α羟化酶／17，20裂链酶联合缺乏症的两姐妹及其父母的CYP17基因序列。方法外周血中提取基因组DNA。设计引物行PCR反应并对PCR产物进行序列测定。结果两姐妹均表现为典型的17α羟化酶／17，20裂链酶联合缺乏，其CYP17基因均为985缺失TAC插入AA的纯合子突变，而其父母是杂合子突变。结论985缺失TAC插入AA杂合子仅是一遗传标志，并不能引起疾病，但这种纯合子突变或在此基础上再发生另一突变可导致疾病的发生。     

室上性心动过速导管消融治疗的新认识

导管消融治疗室上性心动过速(室上速)由于有95%以上的成功率及极低的并发症,成为目前治疗室上速的一线方法。随着心电生理学的进展,室上速电生理机制及治疗方法仍在不断改善。这些新的标测技术和消融方法的进步又进一步提高了治疗手术的成功率。现将近些年室上速消融治疗的一些新认识简述如下。1房室结折返性心动过速(AVNRT)的导管消融治疗房室结折返性心动过速是最常见的室上速之一。传统的理论认为房室结内存在快、慢2个径路,AVNRT时折返环局限在房室结内。这一理论的最有力的支持证据是在AVNRT时心房的激动可以与心动过速分离,由此…

氯米帕明和米氮平治疗抑郁症的疗效比较

目的比较氯米帕明和米氮平治疗抑郁症的疗效。方法80例门诊抑郁症患者随机分为氯米帕明和米氮平治疗组,疗程8周,用汉密尔顿抑郁量表(HAMD),临床疗效总评量表(CGI)和副反应症状量表(TESS)在治疗前及治疗后第2、4、8周末行评定。结果治疗8周后氯米帕明组和米氮平组HAMD减分率分别为71．89%和71．74%,两组治疗前、后比较差异均有显著性(P＜0．01),但两组间比较差异无显著性(P＞0．05)。氯米帕明副反应发生率33．25%,米氮平22．21%两组间比较差异有显著性(P＜0．05)。结论米氮平治疗抑郁症疗效与氯米帕明相当,副反应轻。
