Sci Rep:中国汉族人口中,白细胞端粒长度与年龄相关的听力损失的关系

2017-09-14 AlexYang MedSci原创

年龄相关的听力损失(ARHI)是老年人中最为常见的感官障碍。尽管端粒消减表明可作为各种年龄相关疾病病理上的一个决定性因子,但是端粒长度与ARHI是否存在关系仍旧未知。最近,有研究人员假设了减少的端粒长度(LTL)增加了ARHI的风险。因此,他们通过已经建立的定量PCR技术,测量了666名ARHI患者和43名对照的LTL长度。研究人员利用快速聚类分析方法在研究包括的案例章鉴定了4种ARHI的听力敏度

年龄相关的听力损失(ARHI)是老年人中最为常见的感官障碍。尽管端粒消减表明可作为各种年龄相关疾病病理上的一个决定性因子,但是端粒长度与ARHI是否存在关系仍旧未知。最近,有研究人员假设了减少的端粒长度(LTL)增加了ARHI的风险。因此,他们通过已经建立的定量PCR技术,测量了666名ARHI患者和43名对照的LTL长度。

研究人员利用快速聚类分析方法在研究包括的案例章鉴定了4种ARHI的听力敏度图亚型,包括了扁平形(FL)、2-4kHz的突然下降形(AL)、8kHz的下降形(8D)和倾斜形(SL)。更长的LTL与减少的ARHI发生率相关(调整后OR=0.550, 95% CI: 0.420-0.721, P<0.0001 for all the ARHI; 0.498, 0.318-0.780, P=0.0023 for FL 亚组; 0.428, 0.292-0.628, P<0.0001 for AL 亚组; 0.552, 0.399-0.764, P=0.0003 for mSL 亚组)。另外,与那些具有最短端粒或者中等长度端粒的受试者相比,最长LTL受试者的ARHI风险更低(OR for ARHI: 0.327, 95% CI 0.170-0.629, P=0.0008)。最后,研究人员指出,随着纯音听觉阈值平均值(PTA)程度的下降,LTL也表现出了消减的趋势。这些结果表明了端粒消减也许参与了ARHI的进展。
