Abstract

目的探讨微创股骨近端髓内钉(PFNA)治疗老年股骨粗隆间骨折的疗效.方法回顾性分析采用PFNA治疗的38例老年股骨粗隆间骨折患者的临床资料,其中22例采用闭合复位,16例采用小切口有限切开复位.结果本组均获随访,随访时间6～36个月,平均13个月,复查X线片显示骨折复位良好,无内固定失效、股骨头缺血坏死、髋内翻畸形、下肢深静脉栓塞及死亡病例.术后6个月按Harris评分评定疗效,优21例,良17例,差1例,优良率97.3％.结论在严格把握其适应证及操作技巧的前提下,PFNA是治疗老年股骨粗隆间骨的良好方法,尤其是合并骨质疏松患者的理想固定方法.

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
