简介：目的探讨维持性血透患者合并脑梗死发生的特点、危险因素及治疗转归。方法对14例维持性血透合并脑梗死患者的临床资料进行回顾性分析。结果所有病例行头颅CT扫描检查，其中4例同时行头颅MRI扫描，发现梗死灶：基底节区9例、桥脑2例、小脑2例、半卵圆中心3例、额叶2例，顶叶1例，其中5例呈多发性梗死灶。治疗结果：1例基本痊愈，死亡1例，其余12例遗有不同程度的偏瘫和／或偏身感觉障碍，1例同时有不全性运动性失语。结论高血压和动脉粥样硬化是其发生脑梗死的主要危险因素，纤维蛋白原增高、肾性贫血及EPO治疗亦可能是维持性血透患者发生脑梗死重要的危险因素。

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：根据一项新的研究，添加服用维生素C或E不能帮助预防年龄相关性白内障。白内障或眼睛的晶状体浑浊是老年人失明的主要原因。年龄相关性白内障影响一半以上超过65岁的美国人。手术去除白内障是唯一有效的治疗方法，并且除了戒烟和多吃富含水果与蔬菜的饮食之外，关于如何预防它们知道的很少。

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?
