端粒长度心血管损伤

英国一项研究表明，中年后期白细胞端粒长度(LTL)缩短率与心血管损伤显著相关，并且独立于传统心血管危险因素。论文于6月22日在线发表于《欧洲心脏杂志》(Eur Heart J)。 此项研究从NSHD调查中纳入了在53和60～64岁时测定LTL和传统心血管危险因素，并且在60～64岁时测定颈动脉内中膜厚度(cIMT)、心脏质量和左室功能的受试者。LTL通过实时PCR加以测定。 结果显示，共有10

英国一项研究表明，中年后期白细胞端粒长度(LTL)缩短率与心血管损伤显著相关，并且独立于传统心血管危险因素。论文于6月22日在线发表于《欧洲心脏杂志》(Eur Heart J)。

此项研究从NSHD调查中纳入了在53和60～64岁时测定LTL和传统心血管危险因素，并且在60～64岁时测定颈动脉内中膜厚度(cIMT)、心脏质量和左室功能的受试者。LTL通过实时PCR加以测定。

结果显示，共有1033例受试者同时具备两个时间点的LTL数据。尽管53岁时LTL与60～64岁时心血管表型无相关性，但LTL与60～64岁时cIMT具有负相关性(P=0.015)。然而，53和60～64岁时端粒缩短率与60～64岁时cIMT值具有最显著相关性(P=0.006)。对传统心血管危险因素进行校正后上述相关性未受影响。心脏指标与横断面和纵向LTL测定无相关性。

JNCI：端粒长度短的癌症患者生存期短

　　丹麦一项研究表明，端粒长度短与癌症患者生存期短相关，但与患癌风险无关。该研究论文3月6日在线发表于美国《国立癌症研究所杂志》（J Natl Cancer Inst）。 　　该研究是一项前瞻性研究，测量了47102名丹麦普通人群受试者的白细胞端粒长度，他们来自哥本哈根市心脏研究和哥本哈根普通人群研究。随访时间长达20年，以收集癌症诊断与死亡资料。随访完成率为
