[en] In this paper, the characteristics, clinical manifestations, diagnostic criteria and treatment principles of acute and chronic radiation skin injury caused by external irradiation were analyzed based on domestic and foreign literatures, newly formulated national occupational health standards and the author's clinical experience, etc., which provide basis for timely treatment and standardized diagnosis and treatment of radiation skin injury. Acute radioactive skin injury is divided into I, II, III and IV degrees according to the size and clinical manifestations of the irradiated dose. The clinical course of these four degrees of acute radioactive skin injury not only showed the association between dosage and injury, but also showed the obvious phases of severe radiation injury. Early dose estimation through skin injury degree is helpful for rapid and accurate diagnosis, early prediction of lesion severity and decision of treatment strategy. Chronic radioactive skin injury is caused by long-term exposure to low-dose radiation due to occupational reasons;Another reason is prolonged formation of acute radioactive skin injury, which divided into I, II and III degree. It is only classified according to the degree of skin injury and has no strict dose-effect relationship with the radiation received. The treatment of acute and chronic radioactive skin injury is different according to the degree of injury. Local conservative treatment and surgical treatment using repair methods all consider the promotion effect of systemic treatment on wound healing. (authors)

[en] National occupational health standard-Diagnostic Criteria for External Radiation Bone Injuries has been approved and issued by the Ministry of Health. Based on the extensive research of literature, systematic study of the relevant laws and regulations, this standard was enacted according to its making principles. It is mainly used for diagnosis of bone injury induced by radiation accident, and it also can serve as a guide to diagnose bone injury induced by medical radiation. To implement this standard, and to diagnose and treat the external radiation bone injuries patient correctly and promptly, the contents of this standard were interpreted in this article. (authors)

[en] To explore the methods of clinical classification in chronic radiation-induced ulcers in the chest wall (CRUCWs). A total of 64 patients with CRUCWs were treated. We divided the cases into 3 types (mild, moderate, or severe) according to their clinical manifestations. Conservative treatments, axial-pattern myocutaneous or local flaps, or filleted flaps were applied correspondingly. The cases were divided as follows: mild (n = 11), moderate (n = 45), and severe (n = 8). Eight cases were cured by conservative surgical therapy. One case had a recurrence 6 months after conservative therapy and was cured by a latissimus dorsi myocutaneous flap. The transferred flaps all survived, including 26 transverse rectus abdominis myocutaneous flaps, 8 longitudinal rectus abdominis myocutaneous flaps, 6 latissimus dorsi myocutaneous flaps, 3 contralateral breast flaps, 5 lateral thoracic rotation flaps, and 7 filleted flaps. In 2 transverse rectus abdominis myocutaneous flaps and 2 latissimus dorsi myocutaneous flaps, distal necrosis appeared in small areas. The resulting wounds were salvaged with skin graft and full healing was achieved. CRUCWs can be divided into three types. Surgical methods should vary with distinguished classifications. The effective classification of CRUCWs has definite instructive significance on the selection of surgical approaches.
