[The westward migration of Tongji Medical College during the Anti-Japanese War]

Tongji Medical College began its "education Long March" after the Battle of Shanghai in 1937, with six westward migrations across almost 10,000 kilometers over eight years. It first moved to the city of Shanghai because Tongji Medical College had to rent space in Shanghai, then moved to Jinhua in Zhejiang Province soon afterwards. After that it migrated to Ganzhou and Jian in Jiangxi Province, then He County in Guangxi Province and Kunming in Yunnan Province, ultimately locating in Li Village in Sichuan Province. Tongji Medical College was operated by Chinese and implemented high-level administration and teaching under the difficult conditions during the Anti-Japanese War. As a result, Tongji Medical College made advances in the medical field, such those by Professor Wu Mengchao. It also made advancements in research and treatment, such as identifying pathogenesis of a local epidemic and offering some treatment methods, and popularised medical knowledge for local people by exhibitions and news paper columns. It also established the Number One and the Number Five UMC Trauma Centre, participating in battlefield treatment. The German teachers of Tongji Medical College, who did not move to the west, established a German Medical School in Shanghai. Tongji Medical College returned back to Shanghai, incorporating the German Medical School in Shanghai after the Anti-Japanese War.

[The early graduates from Tongji Medical University(1912-1955)]

The early history of Tongji Medical University can be demonstrated from the graduate certification and the photos of graduates from the Tongji Deutsch Medical School in 1912 to the Wuhan Medical College in 1955. It was found that the names, the chancellors and the affiliations of the university kept changing based on the changing of the names, stamps and signatures of the chancellors on the graduate certificates. It was also found that the apparent morale among graduates appeared to be different during different historical stages in graduate photos. Both graduate certificates and graduate photos show the educational achievements by the Tongji Medical University.

Antigenic determinant of trichosanthin peptide fragments

Purified plant protein, Trichosanthin (TCS), was partially digested with chymotrypsin to produce peptide fragments. Two large fragments, I and II, have been isolated and identified as C-terminal peptides located at sequence positions between 79-234 and 107-234. Their molecular weights determined by electrophoretic mobility on SDS gel were 16,000 and 14,000 daltons. Studies using fluorescence quenching measurements by titrating anti-TCS Fab with TCS and fragment I and II showed that four epitopes were present in intact TCS and one each epitope in fragment I and II. One of the epitopes is therefore located between sequence positions 107 and 234.
