Bluesky正在为Twitter开发一款基于去中心化AT协议的应用程序_我的网站

A 51-year-old patient surnamed Jiang raises his legs after more than a year of treatment following an eight-hour operation at Suzhou Ruihua Orthopedic Hospital in 2024 to reattach both legs, which had been completely severed at the thighs. Photo: Yangtze Evening PostChinese doctors have completed what they called as the world's first replantation involving the complete severing of both legs at thigh level, with the patient now able to walk indoors using a walker following a nearly eight-hour operation, according to a recent report by the Yangtze Evening Post.
The patient, a 51-year-old surnamed Jiang, had both legs completely severed at the thighs in a machinery accident at a factory on December 2, 2024. A multidisciplinary team from the trauma orthopedics and joint surgery departments at Suzhou Ruihua Orthopedic Hospital, in East China's Jiangsu Province, worked through the night for nearly eight hours to reattach the two limbs, the report said.
Li Changsong, head of a trauma orthopedics team at the hospital, told the Yangtze Evening Post on Tuesday that Jiang can now walk indoors with a walker and manage most daily activities without assistance. Sensation in his lower limbs has also recovered to the area above his ankles.
"He is still recovering and is expected to gradually stop using crutches and eventually walk independently," Li was quoted as saying by the Yangtze Evening Post on Wednesday.
In March last year, shortly after the external fixators were removed from both legs, Jiang could already lift his legs freely while lying in bed. Sensation had returned as far down as the middle of his lower legs, and he was discharged from the hospital on March 5. His main goal at the time was to stand and walk again through rehabilitation, according to the report. 
More than a year later, Jiang has moved from being confined to bed to lifting his legs and then standing and walking, the report said, noting that his rehabilitation is still ongoing.
The recovery process has not been without complications. Jiang developed localized skin necrosis after the operation and underwent flap reconstruction surgeries. He later required bone grafting and reinforced internal fixation of both femurs after severe open comminuted fractures resulted in femoral nonunion.
Li said Jiang is now in good overall condition, with his legs approximately equal in length.
"A novelty assessment conducted by the Jiangsu Institute of Medical Information confirmed this as the world's first case of replantation following the complete severing of both thighs," Li said. 
Li said the case was considered a world first primarily because both legs were completely severed at thigh level simultaneously, an extremely rare injury. The hospital had previously accumulated extensive experience in replanting single limbs and lower legs, while its expertise in fracture fixation, vascular anastomosis and nerve repair provided an important technical foundation for the operation, according to the report.
Li did not give a timetable for when Jiang might be able to stop using a walker completely.
"Recovery varies from person to person. We still need to monitor his muscle strength, nerve sensation and fracture healing," Li said. Based on his current progress, however, Jiang's walking ability could continue to improve, the Yangtze Evening Post reported.
Global Times
。早在 2019 年，时任 Twitter CEO 杰克·多西就在首次宣布 Bluesky 时称：它允许我们访问、并为更大的公共对话库做出贡献，将精力集中于构建促进健康对话的开放推荐算法上、同时敦促我们较以往更具创新性。现在看来，AT 协议将成为未来为所有这些应用程序提供支撑的基础技术，只是目前采用 AT 协议的网站等相当稀少。即便如此，它还是从三个方面描绘了未来的去中心化社交网络。首先是“联合社交”（federated social），它允许用户在一项服务之上使用诸多应用程序。其次是“算法选择”（algorithm choice），其决定信息该如何呈现。然后是“移动账户”（portable accounts），意味着相关内容可从一款应用程序轻松转移到另一个，而不会丢失用户已创建的内容和社交图谱。此外在周二的博客文章中，Bluesky 提到了未来潜在的性能优势，称已将“构建大规模快速加载”作为其优先事项。

B | 此前 Bluesky 已经开展了大量的研究和修改，发布了白皮书和 GitHub 存储库。但现在，该公司已决心真实开测该协议，同时希望为感兴趣的开发人员提供一轮封测。当然，就算顺利完成的初期的准备工作，也别指望基于 AT 协议的去中心化社交网络和配套的应用程序，会很快走入你的现实生活。

C | 正如杰克·多西在项目启动时所说的那样，这项工作必须在公开透明的状况下完成、不归属于任何一家私营企业，以拥抱去中心化原则和促进开放式的互联网。

D | 最后，Bluesky 也不是该类别中的唯一项目，比如名气同样很大的 Mastodon、引发一些争议的 DeSocial，且 Bluesky 也有考虑采纳 Matrix、XMPP、Solid 等公司的基础技术进行构建。
