目的：探讨胸膜活检对胸腔积液病因诊断的价值。方法:对268例胸腔积液患者行经胸壁胸膜活检术。结果:268例患者共行胸膜活检289次，二次及以上活检者19例，获取胸膜组织244例，穿刺成功率91%，经病理检查有18例为正常胸膜组织，阳性诊断者为226例，阳性率92.6%（226/244），其病理诊断为结核104例（46%）、肿瘤54例（23.9%）、慢性炎症68例（30.1%）；发生并发症者19（6.6%），全部为气胸，肺压缩均小于30%，未做特殊处理数日后自行吸收。结论:从本组资料可以看出，经胸壁胸膜活检术对于胸腔积液的病因诊断具有非常好的效果，相比胸水涂片或病理检查具有更高的阳性率。因此经胸壁胸膜活检术由于它的简单、安全、高效等特点，目前在胸腔积液病因诊断方面仍是一项重要的手段。
【摘要】 目的 探讨莫西沙星对急性肺脓肿治疗的临床疗效及安全性分析。方法 选择2008年6月—2009年6月收治的36例急性肺脓肿患者,随机分为莫西沙星组和对照组,分别给予静脉滴注莫西沙星和头孢哌酮舒巴坦联合替硝唑治疗。比较两组疗效及安全性。结果 莫西沙星组和对照组总有效率分别为90.63%、93.75%;细菌敏感性分别为73.3%、86.7%;细菌清除率分别为83.7%、92.4%;不良反应总发率分别为16.7%、11.1%。两组比较无统计学差异(Pgt;005)。结论 经验性莫西沙星治疗急性肺脓肿的疗效及安全性与头孢哌酮舒巴坦联合替硝唑相似。但莫西沙星治疗费用低且利于口服序贯治疗而更具有优势,可推荐作为经验性或首选用药。
Objective To evaluate the relationship between COPD and atherosclerosis, and analyze the risk factors of atherosclerosis among COPD patients. Methods A total of 40 COPD patients and 43 normal subjects were enrolled in the study. Carotid intima-media thickness (IMT) and plaques were detected in both groups. Blood samples were collected to measure the concentration of high sensitive C-reactive protein (hs-CRP) , fibrinogen (Fbg) , total cholesterol (TC) , triglyceride (TG) , high density lipoprotein cholesterol (HDL-C) , low density lipoprotein cholesterol (LDL-C) , while smoking index was recorded. Multiple regression analysis was performed to evaluate the correlative factors of IMT among COPD patients. According to whether luminal stenosis appeared, the COPD patients were allocated into group A ( without luminal stenosis) and group B ( with luminal stenosis) . Age, gender, hs-CRP, Fbg, TC, TG, HDL-C, LDL-C, and smoking index of the two groups were compared respectively. Results Hs-CRP, Fbg, thickness of IMT, plaques detection rate, and smoking index in the COPD group were significantly higher than those in the control group ( Plt;0.05) . TC, HDL-C, LDL-C in the COPD group were significantly lower than those in the control group ( Plt;0. 05) .Multiple regression analysis of IMT correlative factors among COPD patients showed that age, hs-CRP, Fbg, TC, TG, LDL-C, HDL-C, and smoking index were in linear relationship with IMT thickening. Age, hs-CRP, TC, and smoking index were positively correlated with IMT ( Plt;0.05) . Hs-CRP and smoking index in the group A were lower than those in the group B ( Plt;0. 05) .While TC, TG, LDL-C, and HDL-C in the group A were higher than those in the group B ( Plt;0.05) . Conclusions Age, smoking index, hs-CRP, and TC are risk factors for thickening of carotid artery IMT in COPD patients. Furthermore, smoking index, hs-CRP, TC, TG, LDL-C, and HDL-C are related to the severity of IMT thickening. The ultrasound detection of carotid artery IMT can be a valuble tool to screen atherosclerosis in patients with COPD.
Objective To explore the relationship between thrombocytosis and all-cause in-hospital mortality in patients with chronic obstructive pulmonary disease (COPD) and low-risk pulmonary embolism (PE). Methods In a multicenter retrospective study on clinical characteristics, COPD patients with proven acute PE between October 2005 and February 2017 were enrolled. The patients in risk classes III-V on the basis of the PESI score were excluded. The patients with COPD and low-risk PE were divided into two groups of those with thrombocytosis and without thrombocytosis after extracting platelet count on admission. The clinical characteristics and prognosis of the two groups were compared. Multivariate logistic regression was performed to reveal an association between thrombocytosis and all-cause in-hospital mortality after confounding variables were adjusted. Results A total of 874 consecutive patients with COPD and PE at low risk were enrolled in which 191 (21.9%) with thrombocytosis. Compared with those without thrombocytosis, the thrombocytopenic group had significantly lower body mass index [(20.9±3.3) kg/m2 vs. (25.1±3.8) kg/m2, P=0.01], lower levels of forced expiratory volume in one second (FEV1) [(0.9±0.4) L vs. (1.3±0.3) L, P=0.001] and lower partial pressure of oxygen in the arterial blood (PaO2) [(7.8±1.2) kPa vs. (9.7±2.3) kPa, P=0.003]. The COPD patients with thrombocytosis had a higher proportion of cardiovascular complications as well as higher level of systolic pulmonary arterial pressure (sPAP) [(46.5±20.6) mm Hg vs. (34.1±12.6) mm Hg, P=0.001]. Multivariate logistic regression analysis after adjustment for confounders revealed that thrombocytosis was associated with all-cause mortality in hospitalized patients with COPD and low-risk PE (adjusted OR=1.53, 95%CI 1.03–2.29), and oral antiplatelet treatment was a protective factor (adjusted OR=0.71, 95%CI 0.31–0.84). Conclusions Thrombocytosis is an independent risk factor for all-cause in-hospital mortality in COPD patients with PE at low risk. Antiplatelet therapy may play a protective role in the high-risk cohort.
