With the rapid development of medical technology, the application of multidisciplinary diagnosis and treatment (MDT) model in the field of rheumatic diseases has become increasingly widespread and in-depth. In order to improve the diagnosis and treatment level of rheumatic diseases and promote interdisciplinary communication and cooperation, the second phase of the Zhihui Rheumatology MDT series conference hosted by Chengdu High tech Medical Association was successfully held online on August 20, 2025. This conference invited experts in the field of rheumatology from both inside and outside the province to give lectures. The content covers a wide range, is more closely related to clinical practice, has strong practicality, and is worth learning for grassroots physicians.
