库欣综合征 (Cushing's syndrome) is named after Harvey Cushing (1869–1939), the founding figure of modern neurosurgery, who first described it in 1932. The transliteration
库 (kù) +
欣 (xīn) maps the English 'Cu-' + '-shing' fairly literally. The
欣 (xīn, 'joyful') is also a popular character in Chinese given names.
