This paper introduces the structure, contents, function of the digital teaching re-courses database in Clinical Skills course of Central South University, analyses the essence and char-acter of the flipped classroom (FC), and emphasizes flexible environment, learning culture, inten-tional content, professional educator in its implementation process. Meanwhile, it introduces the appli-cation of flipped classroom based on digital resources database in the teaching of Clinical Skills course, mentions the importance of the four aspects:preparing teaching materials, learning before class, guidance and cooperation in class, evaluation and knowledge expansion after class. Lastly, it analyses the advantages and foreground of it.

Lumbar brucellar spondylitis is an infectious disease caused by the invasion of brucella. The incidence has been on the rise in recent years. And it threatens people's health seriously. Early and proper diagnosis and treatment is the key to cure patients with lumbar brucella spondylitis. However, in the early stage of the disease, there are only nonspecific symptoms such as back pain, fever, and sweating. If the patient has the above symptoms and epidemiological history of direct or indirect livestock contact, and inflammatory signals of the vertebrae or intervertebral space are visible on MRI, the possibility of early infection of lumbar brucella spondylitis should be considered. It is not difficult to make the diagnosis of lumbar brucella spondylitis in the middle and late stages by taking into account the epidemiology, symptoms, signs, laboratory tests, and the imaging features such as narrowing of the intervertebral space, abnormal signals of the vertebral body and disc, bone destruction and sclerosis, "lace-like" appearance, sequestrum formation and limited paraspinal abscess. Patients in these stages often present with serious manifestations such as lumbar instability due to bone destruction, and the focus is on surgical intervention. The basic principle of surgical treatment is lesion removal combined with fixation. Intraoperative reduction of damage to bone and ligamentous structures such as the posterior ligamentous complex and strong fixation will contribute to the complete cure of the disease. By referring to the literature on lumbar brucellar spondylitis, this paper focuses on the etiology, pathogenesis, clinical manifestations, imaging features, laboratory tests and conservative and surgical treatment of the disease, aiming to provide a basis for clinical diagnosis and treatment.
