复杂性区域疼痛综合征
Health Care(2021)
Abstract
复杂性区域疼痛综合征是神经科或疼痛科常见的一种慢性疾病,通常表现为肢体持久的烧灼样神经痛,临床容易漏诊.一般情况下,普通的疼痛是发作性的,随着疾病的痊愈而消失,但是患了这种疾病,疼痛不会随着时间而消退.相反,疼痛可能会变得慢性和持续. 目前,对导致复杂性区域疼痛综合征的病因尚不明确,但有研究显示周围神经损伤牵涉其中,在大多数情况下,该疾病常发生在对病变区域进行某种类型的伤害后.复杂性区域疼痛综合征被认为是身体对损伤的异常反应,是由于身体对伤害反应过度而引起,控制受伤部位疼痛的神经末梢可能对交感神经系统携带的化学信使过于敏感,放大了损伤对机体的影响.这些化学信使,被称为儿茶酚胺类神经递质,可能会刺激机体产生疼痛和其他症状.此外,也有部分病例是由脊髓病变所致.

- 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
