  • 简介:  目的:分析和总结体外循环心脏手术后合并真菌感染的临床特点及耐药情况。方法:对51例体外循环心脏直视术后继发真菌感染的临床资料进行统计分析,分析术后培养分离出的78株感染真菌的药敏试验结果。结果:心脏术后长期使用广谱抗生素及皮质激素、机械通气、气管切开、APACHEⅡ高评分、全肠外营养及侵入性检查治疗等均是真菌感染高危因素。心脏术后真菌感染部位以下呼吸道为主,其次为血液、静脉导管顶端,继之为泌尿系。大多数真菌菌株对两性霉素B、5-氟胞嘧啶敏感,对大扶康及伊曲康唑部分耐药。结论:合理使用广谱抗生素和糖皮质激素,尽量减少不必要的侵入性操作,加强全身营养及脏器功能支持,改善肠道微生态平衡,密切监测真菌感染的一切临床迹象,注重预防及经验性治疗;治疗上应选择敏感、毒副作用轻的抗真菌药物。

  • 简介:番茄是人们餐桌上常有的蔬果,有人说要生吃,有人说要熟吃,到底番茄怎么吃才更有益健康呢?我们购买番茄时应避免选择未成熟的青色番茄,因其含有毒的龙葵碱,吃多了可能导致中毒,出现头晕、恶心、呕吐及全身疲乏等症状,严重的还有生命危险。因此宜选择个大、圆润、丰满、已经熟透的番茄食用。

  • 简介:目的评估低密度脂蛋白胆固醇(LDL—C)/高密度脂蛋白胆固醇(HDL—C)比值对经皮冠脉介入(PcI)术后患者心血管事件的预测价值。方法选择急性冠脉综合征(ACS)并予前降支置入支架的患者119例,依据血浆LDL—C/HDL—C比值将患者分为3组,随访1年,评估三组患者心血管事件发生率,以及各危险因素与心血管事件发生率的关系。结果①与LDL—C/HDL—C比值较低的两组相比,比值较高组患者体重指数、女性患者百分率、吸烟人数及糖化血红蛋白、高敏C反应蛋(hs—CRP)、总胆固醇和LDL—C水平均明显升高,而HDL—C水平和他汀类药物使用率则较低(P〈0.05)。②第1组风险(HR)1.04,95%可信区间(c,)0.98-1.08,第2组HR1.16,95%C11.08-1.20,第3组HR1.27,95%C11.19~1.36(P〈0.05)。随着LDL—C/HDL—C比值的升高,PCI术后1年患者心血管事件发生率也逐渐升高(P〈0.05)。③Cox比例风险回归模型提示,LDL—C/HDL—C比值对PCI术后心血管事件风险的预测价值优于其他危险因素。结论LDL—C/HDL—C比值对PCI术后患者1年内心血管事件再发具有一定的预测价值。

  • 简介:一个新的研究显示,血液C反应蛋白(C-reactiveprotein,简称CRP)水平高并不会使人发生心脏病和中风的风险升高。C反应蛋白是一种反应人体炎症状态的蛋白。近年来C反应蛋白很受关注,因为有证据显示它与心脏病相关,可能是心脏病的标志物之一。但疑问仍然存在,到底C反应蛋白只是反映心脏存在问题,还是它本身可以导致心脏疾病?
