As the national key discipline and the initiator of oral and maxillofacial deformity group, the Department of Oral and Maxillofacial Surgery persisted in teaching, designed a novel teaching form combining theoretical knowledge and online software practice according to the characteristics of our discipline and carried out "cloud training" via the National Oral Telemedicine Education Platform. Ten lecturers, 325 theoretical students and 50 practical students were investigated by questionnaire in the present study with questions focusing on the geographical distribution and composition of personnel, etc. The results showed that the online course covered a wide range of students and achieved high acceptance and satisfaction rate. The first online software operation course was conducted in an orderly manner, with timely interaction between teachers and students. The students were able to master the design process skillfully. This "cloud training" has achieved good results, but there are still a series of problems that have yet to be resolved, such as network stalls and protection of intellectual property rights. Under the new form, the exploration and analysis of the new mode of online telemedicine specialist education will provide some practical reference for the National Clinical Research Center for Oral Diseases to carry out online telemedicine teaching in the future.

Oral mucosal melanoma (OMM), a subtype of melanoma which is commonly found in the eastern Asian populations, progresses with unclear pathogenesis, high malignancy and poor prognosis. Constructing different types of preclinical models for OMM, which simulate clinical characteristics such as tumor invasion and metastasis, assists screening and efficacy-evaluation of drugs. This would promote personalized treatments for patients with OMM. However, lack of preclinical models makes one of the critical obstacles that hinder the recognition of mucosal melanoma and block the treatment breakthrough in mucosal melanoma. In recent years, certain progress has been made in the construction and application of OMM preclinical models. Various OMM preclinical models have been successfully constructed and carried out for further research, assisting in excavating personalized treatment strategies. In this review, we will summarize the latest progress in the researches on OMM preclinical models.
