Cholangiocarcinoma

Dou Kefeng: publicly available information is limited, and little can be confirmed about this author's identity beyond the fact that the works are found in medical literature. The library holds the representative work Cholangiocarcinoma, a specialized title on this malignant tumor of the digestive system, belonging to the fields of clinical medicine and oncology. Judging from the content, the author focuses on the pathogenesis, diagnostic methods, and treatment strategies of cholangiocarcinoma, writing for clinicians and related researchers and emphasizing a systematic organization of professional knowledge rather than popular science. Such medical monographs typically combine basic research with clinical practice, offering clear explanations of examination, staging, and comprehensive treatment. Because reliable records of the author's dates, nationality, education, and positions are unavailable, this introduction is based only on the work and its classification in the library, with no speculation about personal history; readers seeking academic background should consult the author information in the formal publication.

Chen Guihua is a liver transplantation expert and professor at the Third Affiliated Hospital of Sun Yat-sen University, and has long been engaged in clinical research on liver transplantation and hepatobiliary surgery. Public information about him is currently limited, and only one work of his is included in the collection: the medical title Cholangiocarcinoma. Based on the available information, his writing is closely tied to his clinical research and addresses practical issues in liver transplantation and hepatobiliary surgery, presumably for professional readers. This representative work suggests that his writing focuses on the diagnosis, treatment, and study of a specific disease and belongs to specialized medical writing rather than popular science for general readers. Because little has been disclosed about his life and academic career, a more detailed assessment of his writing style and influence is difficult; readers may understand his work in light of his professional background and its subject matter.

Quan Zhiwei is a Chinese author of medical and health books, though publicly available information about him is limited, and no clear record of his life, education, or professional positions has been found. Three of his works are currently known: Cholangiocarcinoma, Informal Talks on Biliary Stones and Biliary Tumors, and Gallbladder Cancer. All of them deal with tumors and stones of the biliary system and fall within the field of medicine and health popularization. Judging from the titles and subjects, his writing balances professional depth with accessibility: on the one hand, he systematically presents knowledge on the diagnosis and treatment of malignant diseases such as cholangiocarcinoma and gallbladder cancer in monograph form; on the other, he explains the prevention and management of biliary stones and biliary tumors to general readers in an easy, conversational style. This combination of specialized works and popular science writing shows an orientation toward both clinical and professional readers and public health education.
