【摘要】: 背景: 健康长寿是古今中外的人们不懈追求的目标,健康长寿不仅是生命科学研究的永恒主题,也是向生命科学提出的终极挑战。当今社会人口老龄化问题日益严重,延缓衰老,延长健康期、缩短带病期,提高老年人的生活质量,具有重大的科学意义和社会意义。诸多研究资料显示,长寿老人能够推迟老年性疾病的发病时间,甚至完全避免老年性疾病的发生并且能够在生命后期使机体保持良好的免疫状态。血浆细胞因子白细胞介素6(IL-6),肿瘤坏死因子α(TNF-α),白细胞介素10(IL-10)的水平在许多老年性疾病中的变化很大,因此我们推测长寿人群细胞因子IL-6、TNF-α和IL-10水平有异于非长寿人群,并且能够反映长寿老人机体的免疫状态。 目的: 探讨云南省玉溪、沾益两地长寿老人血浆细胞因子IL-6,TNF-α和IL-10水平与长寿的关系,为老年医学的临床工作提供一定数据和依据。 方法: 以云南省玉溪和沾益地区的汉族长寿老人117例(年龄≥90岁)为研究对象,以与长寿老人一起居住的直系亲属为直系对照组,共133例,以与长寿老人居住于同一地域,无血缘关系者(长寿老人后代的配偶)为无关对照组,共96例。采用双抗体夹心酶联免疫吸附法测定血浆细胞因子IL-6、TNF-α和IL-10水平。所有统计分析均采用SPSS13.0统计软件。 结果: 血浆IL-6水平长寿组高于直系对照组和无关对照组,差异有统计学意义(P<0.017),直系对照组与无关对照组相比较,差异无统计学意义(P>0.017),血浆IL-6水平男性长寿组高于女性长寿组,差异有统计学意义(P<0.05),直系对照组内男性组与女性组相比较,差异无统计学意义(P>0.05),男性无关对照组高于女性无关对照组,差异有统计学意义(P<0.05);血浆TNF-α水平长寿组与直系对照组和无关对照组相比较,差异无统计学意义(P>0.017),直系对照组与无关对照组相比较,差异无统计学意义(P>0.017),血浆TNF-α水平各组内男性与女性相比较,差异无统计学意义,(P>0.05);血浆IL-10水平长寿组与直系对照组相比较,差异无统计学意义(P>0.017),长寿组高于无关对照组,差异有统计学意义(P<0.017),直系对照组与无关对照组相比较,差异无统计学意义(P>0.017),血浆IL-10水平各组内男性与女性相比较,差异无统计学意义,(P>0.05)。 结论: 长寿老人血浆IL-6,IL-10水平显著升高,TNF-α水平无显著性升高,表明长寿老人处于一种慢性,轻微炎症状态,在一定程度上间接反应长寿老人机体的免疫功能处于一种稳定的状态。
[Abstract]:Background: health and longevity is the unremitting pursuit of people all over the world. Health and longevity is not only the eternal theme of life science research, but also the ultimate challenge to life science. Nowadays, the aging of the population is becoming more and more serious. It is of great scientific and social significance to delay the aging, prolong the healthy period, shorten the period of carrying disease and improve the quality of life of the elderly. Many studies have shown that the long-lived elderly can delay the onset of senile diseases, even avoid the occurrence of senile diseases completely, and can keep the body in a good immune state at the later stage of life. The levels of plasma cytokines such as interleukin-6 (IL-6), tumor necrosis factor-伪 (TNF- 伪) and interleukin-10 (IL-10) change greatly in many senile diseases. Therefore, we speculate that the levels of IL-6,TNF- 伪 and IL-10 in the longevity population are different from those in the non-longevity population, and can reflect the immune status of the longevity elderly. Aim: to investigate the relationship between plasma cytokine IL-6,TNF- 伪 and IL-10 levels and longevity in Yuxi and Zhanyi areas of Yunnan Province, in order to provide some data and basis for clinical work of geriatrics. Methods: 117 cases (鈮,
