INTRODUCTIONRadiation-induced optic neuropathy (RON) is an infrequent but devastating consequence of radiation exposure to the visual pathways, usually following months to years after the treatment of paranasal or intracranial tumours. Hyperbaric oxygen (HBO) therapy is one of several therapies that have been tried for this condition. The purpose of this review is to describe the clinical characteristics of RON, the rationale for the use of HBO in this condition, and the available clinical data on its safety and efficacy.
METHODSMEDLINE searches were performed on radiation optic neuropathy, hyperbaric oxygen therapy, and similar terms, and selected references were reviewed. The results were combined with the experience at our own institution.
RESULTSRON typically follows a fulminant course with characteristic symptoms, examination findings, and imaging. The threshold for prior radiation exposure depends upon the delivery system used and patient characteristics. Therapy with anticoagulants or steroids has been unsuccessful. While there are case reports in the literature of successful treatment with HBO, therapy with HBO has to be initiated soon after the onset of vision loss, and even then yields variable results at best.
CONCLUSIONSThere is still no consistently successful treatment for RON. HBO may be attempted in selected cases, but the prognosis for preservation of vision remains grim.

3.Chinese consensus on diagnosis and treatment of radiation proctitis (2018).
Chinese Journal of Gastrointestinal Surgery 2018;21(12):1321-1336
Radiation proctitis denotes the radiation damage of rectum caused by radiotherapy to pelvic malignancy. The clinical practices of radiation proctitis should be fully considered from diagnosis, treatment and prevention. In order to determine appropriate treatment strategies, the diagnosis of radiation proctitis should be based on clinical symptoms, endoscopic findings, imaging and histopathology to assess severity of symptoms and stage of disease. In terms of treatment decisions, non-surgical interventions are generally applied to relieve major symptoms and avoid serious complications. Diverting colostomy and restorative resection are the main surgical treatments for patients with recurrent symptoms. In terms of prevention, radiation proctitis should be prevented by improvement of radiotherapy technology, physical protection and prophylactic medication. This guide aims to provide guidance for the clinical practices of radiation proctitis in China.

4.Interpretation of Chinese expert consensus on multidisciplinary diagnosis and treatment of radiation rectal injury (2021 edition).
Chinese Journal of Gastrointestinal Surgery 2021;24(11):956-961
Although pelvic radiotherapy has played an important role in the treatment of malignant tumors, it is still difficult to avoid radiation damage within a certain period of time. In 2021, under the joint promotion of Colorectal Surgery Group of Chinese Medical Association Surgery Branch, Colorectal Surgeons Committee of Chinese Medical Doctor Association Surgeons Branch, Colorectal Surgeons Committee of Chinese Medical Doctor Association, and Colorectal Cancer Professional Committee of Chinese Anti-Cancer Association, Expert Group on Diagnosis and Treatment of Radiation Intestinal Injury has updated and formulated the 2021 edition of the "Chinese expert consensus on the multidisciplinary diagnosis and treatment of radiation rectal injury" (hereinafter referred to as "Consensus"). This Consensus edition has major changes compared with the "Chinese consensus on the diagnosis and treatment of radiation proctitis (2018)", which mainly updates in the following aspects: (1) adjusting the name of radiation rectal injury: the term "radiation proctitis" was adjusted to "radiation rectal injury"; (2) advocating the concept of pelvic integral injury and the multidisciplinary diagnosis and treatment model; (3) putting forward the clinical classification of diseases: the classification of the chronic rectal injury includes telangiectasia, ulcer, stenosis and mixed type; (4) carrying out individualized treatment based on the characteristics of the above-mentioned disease classification, and adjusting the recommended level of non-surgical treatment; (5) proposing specific guiding principles and details of surgical treatment: "damage control" and "expanded resection" principles, etc. This new edition (2021) of Consensus further refines the disease analysis and treatment strategies, which not only improves the guiding value of clinical practice, but also provides an important reference for the standardized diagnosis and treatment of radiation rectal injury in China.

5.Chinese expert consensus on multidisciplinary diagnosis and treatment of radiation rectal injury (2021 edition).
Chinese Journal of Gastrointestinal Surgery 2021;24(11):937-949
Radiation therapy plays a significant role in the integrated treatment for patients with pelvic malignancies, but may lead to radiation-induced rectal injury in some patients, which may affect their physical health and quality of life negatively. Patients with radiation-induced rectal injury are often complicated with pelvic multi-organ injury. Collaborative, multidisciplinary evaluation of pelvic injuries should be highlighted in clinical practices, including clinical, endoscopic, radiological and histopathologic evaluation. To determine the overall treatment strategy and develop individualized treatment strategy, it is necessary to assess the oncologic prognosis, severity and stage of radiation-induced rectal injury and clinical classification using different rating scales. Considering that the disease is self-limiting, non-surgical treatment should be performed for patients with early lesions, while surgical interventions should be performed as soon as possible for patients with severe complications. In terms of prevention of radiation-induced rectal injury, prevention should be targeted for patients at high risk of radiation-induced rectal injury through technique improvement, physical protection and drug prevention. This consensus aims to provide guidance for the clinical practice of radiation-induced rectal injury in China.

7.Studies on the treatment of combined radiation-burn injury.
Chinese Journal of Burns 2008;24(5):387-389
Combined radiation-burn injuries mainly occur under the circumstances of nuclear explosion, nuclear accident, nuclear terrorism, depleted uranium attack, as well as secondary injuries following attack on nuclear installation. Combination of burn and radiation injuries bring along more serious whole body damage, more complicated pathological mechanism and much more difficult management. Research progress on the pathological mechanism and medical management of several key links of combined injury were discussed in this paper. (1) Enhancement of early first aid and prevention of early death of wounded. (2) Damage and restoration of hemopoietic function. (3) Disturbance of immune function and prevention and treatment of infection (mainly on the intestinal mucosa immunity and enterological infection). (4) Management of burn wound. (5) The role of several important measures in the comprehensive treatment.

This article reports the treatment of a patient suffered from acute radiation burn covering 41% TBSA, with deep partial-thickness and full-thickness injury, produced by exposure to a large-scale industrial electron accelerator. An open wound began to appear and enlarged gradually 10 weeks after the exposure. Serious wound infection with methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa, pneumonia, respiratory failure, systemic inflammatory response syndrome, nephropathy and hypoproteinemia developed successively since 3 weeks after the wound formation. Skin grafts failed to survive, resulting in enlargement of the wound. After being treated with proper measures, including parenteral nutrition, respiratory support with a ventilator, appropriate antibiotics, steroid administration for nephropathy, deep debridement for wounds followed by skin grafting, the patient was cured and discharged after undergoing 15 operations in 500 days. The clinical condition of an extensive acute radiation burn is complicated. We should pay close attention to the changes in functions of organs, and strengthen the therapeutic strategies to support the function of organs to reduce the incidence of systemic complications. The control of the infection and the timely and effective repair of the wound are still the key points of the treatment of an extensive local radiation injury.

Because no report has been issued on the healing effects of low-intensity pulsed ultrasound on moderate to large fracture gaps, we performed an experimental study using acanineulna full-defect model. Ten mongrel male dogs were divided into two groups: a small defect group and large defect group. The defects were made on the middle one third of both ulnae and one side only was randomly selected for ultrasound sonication, at 1 MHz, 200 microsecond bursting sine wave in 50 mW/cm2 spacial average and temporal average. Sonication was started on the day after surgery and applied for 15 minutes once a day for six days a week. In the small defect group, the means of the radiologic scores, as described by Lane and Sandhu, were 0.6, 4.4, and 8.4 in the control side and 1.8, 6.0, and 10.4 in the treatment side one, three, and five months after the operation, respectively (p=0.0372). In the large defect model, the corresponding means were 2.2, 3.4, and 6.0 in the control side and 3.3, 5.4, and 9.2 in the treatment side (p= 0.009). Low-intensity pulsed ultrasound enhanced new bone formation in small and large full-defects and decreased the incidence of nonunion in the large defect model.
