简介：C-反应蛋白是机体非特异性炎症反应的敏感标志物,可能参与心血管疾病的发生和发展,当它增高时,可能预测未来心血管事件的发生.对C-反应蛋白在某些方面也存在激烈的争论.

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：我们都会有一些健忘的时候，例如：钥匙在哪里、为啥要走进房间、那个东西叫什么等等。这些情况很有可能反应了思维能力的年龄相关性变化。美国麻省总医院行为神经学及神经精神病学专家萨利纳斯博士说：“随着时间推移，每个人的脑功能在所有领域都会出现衰退，但是，单词量却是个例外。”

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?

简介：目的探讨广谱氯离子通道阻滞剂4，4’-二异硫氰基芪-2，2’-二磺酸（DIDS）对大鼠缺血再灌注损伤心肌细胞凋亡的影响及其机制。方法雄性SD大鼠36只随机分为3组：缺血再灌注组（A组）、DIDS处理组（B组）和LY294002预处理组（C组）。伊文兰和TTC染色测定心肌梗死范围，TUNEL方法定性和定量检测心肌细胞凋亡指数，Westernblot测定蛋白激酶B（Akt）的表达。结果与A组比较，B组心肌梗死范围和心肌细胞凋亡指数明显降低[（38．8±7．7）％”（54．2±10．8）％，（8．9±1．8）％”（17．6±3．5）％．P〈0．01]；磷酸化Akt表达水平明显增加（P〈0．01）。与A组比较，C组梗死面积、凋亡指数无明显减小，磷酸化Akt水平无明显变化（P〉0．05）。结论DIDS能够抑制大鼠缺血再灌注所致的心肌细胞损伤，可能是通过信号分子磷脂酰肌酶三羟基激酶／Akt的调节。
