ACS Nano:神奇研究用“磁铁”指引纳米颗粒 对抗动脉硬化!

2016-01-12 佚名 生物谷

在工业化程度较高的一些国家,患动脉硬化的人特别多,动脉硬化会带来致命后果:动脉血管中出现的斑块沉积会导致中风和心脏病的发生。来自德国波恩大学的研究人员开发了一种新方法利用纳米颗粒引导新细胞靶向血管病变部位,从而对抗动脉硬化。科学家们证明在小鼠体内这些新细胞确实能够在病变部位发挥治疗效果,但在应用于人类疾病治疗之前仍然需要更多研究进行验证。   相关研究结果发表在国际学术期刊ACS N

在工业化程度较高的一些国家,患动脉硬化的人特别多,动脉硬化会带来致命后果:动脉血管中出现的斑块沉积会导致中风和心脏病的发生。来自德国波恩大学的研究人员开发了一种新方法利用纳米颗粒引导新细胞靶向血管病变部位,从而对抗动脉硬化。科学家们证明在小鼠体内这些新细胞确实能够在病变部位发挥治疗效果,但在应用于人类疾病治疗之前仍然需要更多研究进行验证。

 
相关研究结果发表在国际学术期刊ACS NANO上。
 
在动脉硬化发生过程中,动脉血管内部会逐渐形成病理性沉积导致血管狭窄,而中风和心脏病就是血管狭窄导致血供不足造成的常见结果。沿血管分布的内皮细胞发生损伤通常是动脉硬化发生的一个重要内在因素,研究人员表示,内皮细胞能够产生一氧化氮,调节血管扩张以及血压,因此内皮细胞在动脉血管中发挥重要作用。他们开发的这项新技术就是通过基因改造的内皮细胞替换损伤的内皮细胞达到治疗目的。
 
研究人员首先利用病毒将负责产生eNOS酶的基因导入体外培养的内皮细胞中,这种酶能够刺激一氧化氮的合成,随后他们又将这种基因改造的细胞与含有铁核心的纳米颗粒结合在一起,研究人员解释道,纳米粒子的铁核心能够使内皮细胞带有磁性,他们还开发了一种特殊的环状磁铁,保证纳米颗粒能够引导装载了eNOS基因的内皮细胞到达血管病变部位执行修复功能。
 
他们在颈动脉内皮细胞发生损伤的小鼠体内注射了替换细胞,并通过磁铁引导替换细胞到达正确位点。随后研究人员移除了磁铁并检测了新鲜细胞是否获得了一氧化氮合成功能,结果表明这些新的内皮细胞能够产生一氧化氮刺激血管扩张,就像正常的动脉血管一样。
 
目前医生主要通过手术去除颈动脉的沉积物,有时还会放一个血管支架保证动脉狭窄部位能够进行正常的血液流通,但这些区域经常会再次发生堵塞。这项新技术从根本上解决了这一问题,对于动脉硬化治疗以及中风和心脏病的预防和治疗具有非常重要的意义。

Diabetes Obes Metab:依帕列净可降低2型糖尿病患者血压

研究者对2型糖尿病患者进行了一项研究,探究依帕列净对该类患者血压和动脉硬化和血管阻力相关标志物的影响。研究者对两个关于2型糖尿病患者的队列研究进行了数据分析,队列1共有 823名患者服用依帕列净12周,实行24小时血压监测;队列2共有2477名患者服用依帕列净24周,坐在办公室测量血压。研究数据显示,与对照组相比依帕列净使两组队列的收缩压和舒张压均下降(p < 0.001 ),且不增快心率。

Diabetes Obes Metab:短期补充维生素D能否影响HbA1c?

先前有研究表明25(OH)D含量与2型糖尿病和冠状动脉存在风险呈负相关,但并没有估计两者间的因果联系。研究者对糖尿病风险增加的人群进行了一项研究,探究短期内服用维生素D补充剂对心血管代谢疾病的预后影响。该双盲安慰剂对照随机试验共纳入了340名2型糖尿病风险增加成年人(非糖尿病的高血糖症或糖尿病风险评分阳性),将其随机分为维生素D2 100,000 IU或维生素D3 100,000 IU和安慰剂组。

Atherosclerosis:心-踝血管指数预测肥胖患者心血管事件的发生

目的:心-踝血管指数(CAVI)是不依赖于动脉血压的一项显示动脉硬化的指标,是评估动脉功能障碍的指标。然而,CAVI是否能够预测肥胖病人的心脑血管疾病(CVD)的预后尚不清楚。方法:日本肥胖和代谢综合征研究中心招募425名日本肥胖门诊病人(189名男性,平均年龄51.5岁),进行一项多中心前瞻性群体研究。首先,进行包括CAVI等指标的心血管危险因素的监测,进行为期五年的随访确定患者大血管并发症的发

Am J Clin Nutr:虾青素能否改善肾移植接受者动脉硬化风险?

先前有证据表明,肾移植接受者动脉粥样硬化会加速,而动脉粥样硬化会显著增加心血管疾病的发病率和死亡率。高发病率的动脉粥样硬化与动脉硬度增加、血管功能障碍、氧化应激加剧、与免疫抑制治疗相关炎症等有关。而类胡萝卜素虾青素具有强大的抗氧化和抗炎特性。因此研究者对肾移植接受者进行了一项研究,探究口服虾青素对动脉硬化、氧化应激和炎症的影响。该随机、安慰剂对照、双盲试验纳入了61名肾移植接受者,试验组每天口服虾
