不同固定方式对兔肝动脉介入插管的影响
Journal of Interventional Radiology（2020）
Abstract
目的 探讨两种不同固定方式对兔肝动脉插管技术难度的影响.方法 30只新西兰大白兔固定于自制木质平板手术台上行CT增强扫描,获取动脉期腹腔干和腹主动脉信息,CT多曲面重建获取腹腔干及其下层面腹主动脉间夹角;采用改良固定方式固定30只实验兔并获取腹腔干和腹主动脉间夹角.比较两种固定方式下兔腹腔干和腹主动脉夹角的差异.将30只实验兔随机分为实验组与对照组,实验组以改良固定方式固定兔,行股动脉穿刺肝动脉插管,对照组兔固定于木质平板手术台行肝动脉插管,获取并比较两组实验兔手术成功率、手术操作时间及手术并发症发生率.结果 平板固定方式下腹腔干和腹主动脉间夹角为117.93°±13.42°,改良固定方式下夹角为144.40°±14.76°(P＜0.05);对照组肝动脉插管手术成功率为66.7％(10/15),实验组为100％(15/15)(P＜0.05);对照组血管夹层发生率为26.7％(4/15),实验组为0％(P＜0.05);对照组平均手术操作时间为(504.40±47.25)s,实验组为(88.87±14.99) s(P＜0.05).结论 改良固定方式可改变兔腹腔干和腹主动脉夹角,有效降低肝动脉插管的技术难度,降低并发症发生率,缩短手术时间,提高操作成功率.

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
