研究发现睡眠不好或增加患癌风险

2014-02-24 佚名 新华社

睡眠质量不高现已成为许多人的常见问题。近日发表的一项研究结果表明,睡眠不好可能会增加患癌的风险。 以色列Rambam医疗中心的法赫德·哈基姆和美国同行最近在学术期刊《癌症研究》上发表报告说,动物实验显示,碎片化和断断续续的睡眠会影响免疫系统,使其抗癌能力减弱。 哈基姆说,他们把实验鼠分为两组,一组实验鼠的夜间睡眠多次被打断,而另一组则享有不受干扰的夜间睡眠。一周

睡眠质量不高现已成为许多人的常见问题。近日发表的一项研究结果表明,睡眠不好可能会增加患癌的风险。

以色列Rambam医疗中心的法赫德·哈基姆和美国同行最近在学术期刊《癌症研究》上发表报告说,动物实验显示,碎片化和断断续续的睡眠会影响免疫系统,使其抗癌能力减弱。

哈基姆说,他们把实验鼠分为两组,一组实验鼠的夜间睡眠多次被打断,而另一组则享有不受干扰的夜间睡眠。一周后,分别给两组试验鼠注入癌细胞,并在随后几周中继续将它们置于两种不同的睡眠模式中。结果发现,那些睡眠常被打断的实验鼠体内,肿瘤生长程度是睡眠良好实验鼠的两倍。

Cancer Res:睡眠质量差,可以加速肿瘤发展

    科学家们发现,睡眠质量差会加速癌细胞的生长,提高肿瘤的侵袭能力,抑制免疫系统控制和清除早期癌细胞的能力。文章于一月二十一日发表在Cancer Research杂志上。    这是首次在动物模型中展示,片断化睡眠对肿瘤生长和侵袭能力的影响。此外,研究还为人们提供了这种影响背后的生物学机制,鉴定了癌症治疗的潜在靶标。  &n

儿童睡眠中惊叫、乱走1例报道

人为什么要睡觉?自古希腊以来,这个问题一直让哲学家和科学家着迷。从实际的角度来看,睡眠是一个令人费解的生物状态,特别是从果蝇到露脊鲸,几乎每一个动物物种都多少有睡眠的状态。但是,这个睡眠期有显着的缺点,睡着了似乎就失去了对周围环境的警觉,尤其对于食肉动物而言。如果睡眠不执行重要的生物学功能,那么其也许是进化中的最大错误之一。 虽然最近一些科学调查结果显示,睡眠可以

人类及动物模型研究表明睡眠、觉醒—睡眠模式及空腹—摄食周期均在心脏代谢和健康中发挥着重要作用。 睡眠时间短的人更易在极短时间内患肥胖症及糖尿病。现代社会许多人睡得很晚,并且在不同的时间吃饭。如果在一天中错误的时间吃饭,就会增重。不按照正常昼夜节律饲喂,白天摄入相同的食量却较夜间进食引起明显的体重增加。在人类也观察到了相似的现象,例如换班制的工人中肥胖症、心血管疾病以及糖尿病的发病风险增加。 食
