原文（作者为博士后）：

结论  该入路（改良Kocher–Langenbeck入路）对单纯、移位性、非粉碎性髋臼后壁骨折，手术时间较短，可防止股骨头血供的进一步损害和骨化性肌炎的发生，不失为较好的一种手术入路选择。

Conclusion  The modification approach treatment posterior wall fractures of acetabulum, the surgery time is short, may prevent the head of the femur blood supplies the further harm and the ossification myositis occurrence, does not lose for the good one kind of operative approach choice.

该Conclusion的翻译不够准确和顺畅，甚至有些错误。作者修改后：

Conclusion  The surgical approach advantage is that operation time is short, the operation can effectively prevent avascular necrosis and myositis ossificans happening, is a good method.

表达仍然不准确，不顺畅。故校正为：

Conclusion  The modified Kocher–Langenbeck approach takes a shorter operative time for isolated, displaced, non-comminuted posterior wall fractures of acetabulum, and prevents femoral blood supply from further damage and ossification myositis, which is a better alternative approach for stabilization of posterior wall fractures of acetabulum.

摘要  调节性T细胞（Treg）是一群具有免疫调节功能的T细胞亚群，其功能异常可导致多种自身免疫病。类风湿关节炎（RA）是一种主要累及周围关节的多系统炎症性自身免疫病，多种免疫细胞与其发病存在密切关联。本文回顾近年来有关CD4⁺Treg及其在RA中的研究进展情况，为进一步研究RA的发病机制和治疗打下基础。

Abstract  Regulatory T cells (Tregs) are a subset of T cells which are involved in keeping peripheral immune tolerance and have attracted much interest in their role in controlling autoimmunity. Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disorder which predominantly attacks the peripheral joints. This review focused on the current understanding of several subsets of regulatory T cells and the advances of relations between Tregs and RA were summarized.
