Diabetes Care:低脂联素水平或增加心肌梗塞病人2型糖尿病的患病风险

2014-11-06 佚名 生物谷

近日,来自哥本哈根根措夫特大学医院的研究人员通过研究表明,机体脂联素水平较低或和心肌梗塞病人患2型糖尿病风险增加相关,相关研究刊登于近日的国际杂志Diabetes Care上。 文章中,研究者Lindberg表示,急性心肌梗塞(MI)病人患2型糖尿病的风险往往会增加,而脂联素是脂肪细胞分泌的一种胰岛素致敏性激素,其可以直接抑制肝糖异生作用,从而刺激脂肪酸的氧化及骨骼肌中葡萄糖的摄取及胰岛素的

近日,来自哥本哈根根措夫特大学医院的研究人员通过研究表明,机体脂联素水平较低或和心肌梗塞病人患2型糖尿病风险增加相关,相关研究刊登于近日的国际杂志Diabetes Care上。

文章中,研究者Lindberg表示,急性心肌梗塞(MI)病人患2型糖尿病的风险往往会增加,而脂联素是脂肪细胞分泌的一种胰岛素致敏性激素,其可以直接抑制肝糖异生作用,从而刺激脂肪酸的氧化及骨骼肌中葡萄糖的摄取及胰岛素的分泌。肝糖异生作用是机体长期饥饿下维持血糖平衡的主要途径,其主要依靠激素的调节。

在正常人类机体中,血浆中较低的脂联素水平和2型糖尿病的发病风险增加直接相关,然而截止到目前为止科学家还并没有调查过急性心肌梗塞病人机体中脂联素水平和2型糖尿病的发病风险之间的内在关联。

文章中研究人员对2006年9月至2008年12月期间在三级心脏中心救治的666名ST段抬高心肌梗死患者进行分析研究,这些研究对象均未患糖尿病,都通过经皮冠状动脉介入治疗的疗法来治疗心肌梗塞。在患者进行措施干预前研究者采集血样并对所有样本的总血浆脂联素的水平进行测定,随后利用竞争危险分析(competing risk analysis)对患者的2型糖尿病风险进行分析。

结果显示,患者低脂联素水平和2型糖尿病风险增加相关,研究者在调整了所有混杂的影响因子后(包括年龄、BMI、血糖、HDL、LDL等)发现,脂联素水平仍然是一个独立预测2型糖尿病的预测指标;更重要的是,血浆中的脂联素可以增加血糖的预测价值,即高血糖和低脂联素水平的结合可以大大增加个体患2型糖尿病的风险。

最后,研究者Mogelvang教授说道,低脂联素水平与MI患者2型糖尿病风险增加独立相关,而且血浆中脂联素的水平较低可以明显增加机体血糖的预测价值;本文研究为揭示心肌梗塞病人机体脂联素水平和患2型糖尿病之间的风险,也为开发抑制MI患者糖尿病风险的新型疗法提供了研究数据和思路。

干细胞“配方”为糖尿病患者带来曙光

  Douglas Melton 图片来源:B. D. COLEN   Douglas Melton与其他患者一样,在焦急地等待着治疗糖尿病的方法。他的儿子在婴儿时期就患上了糖尿病,女儿在14岁时也确诊患有该病。在过去20年中,这位美国哈佛大学干细胞研究所的发育生物学家一直致力于寻找攻克糖尿病的方法。   近日,他和同事报告了迈向该目标的重要一步:将人体干细

Cell:干细胞来源胰岛B细胞 未来或可根治糖尿病

随着人们生活水平的提高,糖尿病也已经成为困扰许多人的"富贵病"之一。这也使得糖尿病药物市场成为了世界许多生物医药巨头的兵家必争之地。一直以来,药物研发人员都希望能够开发出一种与患者有高度相容性,且能够"智能"响应患者体内血糖变化而不必进行反复注射的疗法。而最近,哈佛大学的研究人员已经朝这一方向又迈出了可喜的一步。他们利用干细胞分化形成了大量的胰岛B细胞。与此前的一些类似实验不同,此次研究人员获得

Cell:对抗糖尿病、炎症的天然武器

自Salk研究所和贝斯以色列女执事医疗中心(BIDMC)的科学家们发现了一种在人类和小鼠脂肪中生成的新分子,其可以预防糖尿病。研究人员证实给予2型糖尿病小鼠这类新脂质可以降低它们升高的血糖。此外,该研究小组还发现在糖尿病高风险人群中这种新脂质的水平降低,表明其有可能可以被用作为代谢性疾病的一种新疗法。研究结果描述在10月9日的《细胞》(Cell)杂志上。像胆固醇一类的脂质通常与健康不良相关联。然而

Lancet Diab & Endo:聚焦中国糖尿病危机

目前我国成人2型糖尿病患病人数超过1亿,居全球之首。2型糖尿病及其并发症已成为我国最为主要的公共卫生危机之一。预计到2030年,中国糖尿病的医疗开支将达到3600亿元人民币。 9月11日,The Lancet Diabetes & Endocrinology 杂志发表了三篇系列综述聚焦我国糖尿病危机。中国科学院上海生命科学研究院营养科学研

Am Heart J:糖尿病及其胰岛素治疗与CABG患者临床转归差相关

美国一项研究表明,在冠脉旁路移植(CABG)患者中,伴糖尿病患者的静脉移植失败发生率与未伴者相似,但其临床转归较差。胰岛素治疗者的临床转归则显著差于非治疗者。论文于10月23日在线发表于《美国心脏杂志》(Am Heart J)。 此项研究利用来自于PREVENT IV的3014例患者数据,在伴和未伴糖尿病以及GABG前接受和未接受胰岛素治疗的患者中分析了血管造影和临床转归。利用Logis

Diabetes:适度晒太阳或可减缓个体糖尿病的发生及体重的增加

近日,来自爱丁堡大学等处的研究人员通过研究发现,适度晒太阳或许会减缓小鼠肥胖及糖尿病的发生;后期研究者还将进行更为深入的研究来证实是否人类个体适度晒太阳会降低患糖尿病和肥胖的风险,相关研究成果刊登于国际杂志Diabetes上。 文章中,研究者发现,耀眼的紫外线会减缓过度喂食小鼠的体重增加,而且小鼠患糖尿病的风险会降低,比如异常葡萄糖水平及对胰岛素的耐受性会降低。紫外线疗法的益处和化合物一氧化
