Not until the beginning of the 1930s did the Class 01 become the predominant express train locomotive of the Deutsche Reichsbahn. By 1938 there were 231 Class 01 locomotives available for the prestigious express train duties.

The British Rail Class 01 diesel locomotive is a short wheelbase 0-4-0 diesel-mechanical design intended for use in areas with tight curves and limited clearance. Four examples were built by Andrew Barclay Sons & Co. of Kilmarnock (Scotland) in 1956.

2021年10月26日 · 南方医科大学南方医院 李国新教授等中国学者在中国 14 个中心发起的 中国腹腔镜胃肠外科研究 [CLASS]–01， 进一步证明了腹腔镜胃切除术对术前评估为局部晚期癌症的患者的安全性和有效性，该项研究的 5 年结果于近日在线发表在 《JAMA Surgery》上。

Therefore, the Chinese Laparoscopic Gastrointestinal Surgery Study (CLASS) group conducted a multicenter randomized trial (CLASS-01 trial) to determine the noninferiority of laparoscopic distal gastrectomy (experimental group) compared with open distal gastrectomy (control group) for 3-year disease-free survival among patients whose ...

该研究旨在回答腹腔镜治疗局部进展期胃癌的安全性和肿瘤学疗效问题，以临床分期T2、T3或T4a的胃癌患者为研究对象，采用多中心、随机对照的试验设计，以3年无瘤生存率为主要研究终点，手术并发症、3年总生存率、术后关键恢复指标等为次要终点,来自全国14家中心的1056名受试者入组该研究。 2016年，CLASS-01研究的手术安全性成果发表在美国临床肿瘤学会ASCO官方期刊《临床肿瘤学杂志》（Journal of Clinical Oncology, IF：24.008）,与传统开腹手术相比，腹 …

2022年1月1日 · Objective: To report 5-year overall survival data from the CLASS-01 trial of laparoscopic vs open distal gastrectomy among patients with locally advanced gastric cancer. Design, setting, and patients: This was a noninferiority, open-label, randomized clinical trial conducted at 14 centers in China.

2019年5月28日 · Importance: Laparoscopic distal gastrectomy is accepted as a more effective approach to conventional open distal gastrectomy for early-stage gastric cancer. However, efficacy for locally advanced gastric cancer remains uncertain.

我国胃肠微创外科发展日新月异，中国腹腔镜胃肠外科研究组 (CLASS)作为成立最早、多中心合作最紧密的外科临床研究协作组织，在中华医学会、中国医师协会、中国抗癌协会的共同指导和帮助下，临床研究能力与微创技术水平持续提升。

2018年6月12日 · CLASS-01（ASCO Abs4058）是关于腹腔镜和传统开腹治疗局部进展期远端胃癌的前瞻性多中心随机对照研究。 这项研究启动于2012年，是由中国14家大医院联合开展的多中心研究，主要目的是评价腹腔镜手术在进展期胃癌外科治疗的价值，主要观察指标是3年无疾病生 …
