    Abstract
    目的 应用超声斑点追踪技术(STE)评价缩窄性心包炎(CP)及限制型心肌病(RCM)患者左房节段心肌功能,探讨其在鉴别CP及RCM中的作用.方法 对35例CP患者及30例RCM患者应用斑点追踪技术测量左房侧壁及房间隔收缩期应变(S)及应变率(SrS)、舒张早期应变率(SrE)、舒张晚期应变率(SrA).结果 (1) CP患者房间隔S、SrS、SrE、SrA较RCM患者明显增加(P＜0.05),房间隔SrE以1.40为截点值鉴别CP和RCM的灵敏度和特异度分别为94.7％和89.7％ (AUC=0.97,P＜0.05).结论 STE可以准确评价CP患者及RCM患者节段左房功能,并在二者的鉴别诊断中具有重要作用.

    • 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
