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.
ObjectiveTo analyze the clinical characteristics and related prognostic factors of post-renal transplantation pneumonia.MethodsThe clinical data of 89 patients with post-renal transplantation pneumonia in Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital from 1st January 2014 to 31st December 2015 were collected in the study. Kaplan-Meier method was used to calculate overall survival. Cox analysis was used to analyze the related prognostic factors.ResultsPost-renal transplantation pneumonia occurred mainly within 6 months after renal transplantation. The prominent clinical manifestations were cough (95.5%), fever (56.1%), and dyspnea (12.3%). The mortality of post-renal transplantation pneumonia was 11.2% and all death occurred within 5 months after transplantation. The overall survival rate significantly decreased in the patients with C-reactive protein (CRP) ≥40 mg/L (P<0.001), procalcitonin ≥1 ng/ml (P=0.002), brain natriuretic peptide >100 pg/ml (P<0.001), platelet ≤100×109/L (P<0.001), or those with occurrence time of pneumonia <180 days (P=0.013). Platelet ≤100×109/L could increase the risk of death by 66.6 times (RR=0.015, P=0.006), and CRP ≥ 40 mg/L could increase the risk of death by 20 times (RR=0.05, P=0.029).ConclusionsPost-renal transplantation pneumonia has prominent clinical characteristics. Platelet ≤100×109/L or CRP ≥40 mg/L can increase the risk of death and can be used as an independent prognoctic factor of post-renal transplatation pneumonia.
