    Abstract
    [目的]通过对经典滚转试验(roll test)的改良,探讨其对水平半规管良性阵发性位置性眩晕的诊断价值.[方法]收集2017年10月1日至2019年12月31日在同济大学附属上海市第四人民医院神经内科头晕门诊就诊的57例水平半规管良性阵发性位置性眩晕(Horizontal Canal Benign Paroxysmal Positional Vertigo,HC-BP-PV)患者临床资料,同时予经典的roll test和改良的roll test(头位滚转从90°改良成180°),比较两者对眼震持续时间以及HC-BPPV患侧确诊的影响.[结果]患侧与健侧眼震持续时间及持续时间差的比较,无论是游离性耳石、还是黏附性耳石,改良roll test与经典roll test的差异均有统计学意义(P<0.05);对于游离性耳石患侧的确诊率,改良roll test与经典roll test差异无统计学意义(P=0.242>0.05),对于黏附性耳石的确诊率,两者差异有统计学意义(P<0.05).[结论]改良roll test相对经典roll test使两侧眼震差异更明显,有助更好判断HC-BP-PV的患侧,有效提高黏附性耳石HC-BPPV患侧的确诊率,但对游离性耳石HC-BPPV患侧的确诊率影响不大.

    • 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

    【要点】：本研究提出改良滚转试验，提高了对水平半规管良性阵发性位置性眩晕中黏附性耳石患侧的诊断准确性，对游离性耳石的诊断准确性则无明显影响。
    

    【方法】：通过比较经典滚转试验与改良滚转试验（头位滚转从90°改良成180°）对眼震持续时间及患侧确诊率的影响。
    

    【实验】：收集57例水平半规管良性阵发性位置性眩晕患者，进行经典roll test和改良roll test，结果显示改良roll test对黏附性耳石的患侧确诊率有统计学意义的提升(P<0.05)，而对游离性耳石的确诊率影响不大(P=0.242>0.05)。
