不同短时收缩压变异性指标与老年人群臂踝脉搏波传导速度的相关性
Chinese Journal of Gerontology（2018）
Abstract
目的 探讨不同短时收缩压(SBP)变异性(SBPV)指标与老年人群臂踝脉搏波传导速度(baPWV)的相关性.方法在参加开滦研究队列第三次健康体检的人群中,采取整群抽样的方法随机抽取年龄≥60岁的开滦集团离退休员工进行24 h动态血压监测等检查.在随机抽取的3064例观察对象中,符合入选标准者2464例,最终纳入统计分析者1004例.SBPV采用标准差(SSD)、独立变异性(VIM)、极差(MMD)和平均真实变异性(ARV)为观察指标.采用逐步线性回归方法,分析不同短时SBPV指标与baPWV的相关性.结果 ①除VIM外,随着平均SBP的增加,短时SBPV指标SSD、MMD、ARV均呈上升趋势(P<0.05).②在逐步线性回归分析中,校正其他混杂因素后,不同短时SBPV指标均与baPWV无线性相关(P>0.05),短时平均SBP均与baPWV呈正相关(P<0.05).结论 不同短时SBPV指标与baPWV均无线性相关.

Key content
- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
