Radiochemotherapy-induced oral mucositis (OM) is a common oral complication in patients with tumors following head and neck radiotherapy or chemotherapy. Erosion and ulcers are the main features of OM that seriously affect the quality of life of patients and even the progress of tumor treatment. To date, differences in clinical prevention and treatment plans for OM have been noted among doctors of various specialties, which has increased the uncertainty of treatment effects. On the basis of current research evidence, this expert consensus outlines risk factors, clinical manifestations, clinical grading, ancillary examinations, diagnostic basis, prevention and treatment strategies and efficacy indicators for OM. In addition to strategies such as basic oral care, anti-inflammatory and analgesic agents, anti-infective agents, pro-healing agents, and photobiotherapy recommended in previous guidelines, we also emphasize the role of traditional Chinese medicine in OM prevention and treatment. This expert consensus aims to provide references and guidance for dental physicians and oncologists in formulating strategies for OM prevention, diagnosis, and treatment, standardizing clinical practice, reducing OM occurrence, promoting healing, and improving the quality of life of patients.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Adenosine triphosphate(ATP),as a rich energy currency in cells,is released into the extracellular space through a variety of regulatory mechanisms.The role of extracellular ATP(eATP)and related purine and pyrimidine nucleotides as extracellu-lar signal molecules regulating immune cell function has been reported as evidence of purine signal transduction and has become the focus of attention as a therapeutic target for various diseases.Mast cells(MC)are distributed in tissues that come into contact with the external environment and are the first immune cells to respond to non-microbial environmental antigens.Although eATP is considered to be an activator of MC,the details remain to be further elucidated.This article describes the role of purine receptor signaling in MC degranulation.It expands the further understanding of the mechanism of allergic diseases,and further provides ideas for finding new targets for the treatment of allergic diseases and formulating new treatment strategies.

Objective:To investigate the effect of intraoperative protection of the supraclavicular nerve on the healing of clavicular 1/3 mid-shaft fracture.Methods:A retrospective study was conducted to analyze the 83 patients who had been treated for clavicular 1/3 mid-shaft fractures at Department of Orthopaedics, The First Central Hospital of Baoding from June 2021 to March 2022. There were 57 males and 26 females with an age of (48.1±12.8) years. The patients were divided into 2 groups according to whether the supraclavicular nerve was protected or not during operation. There were 39 cases in the observation group (the supraclavicular nerve was protected during operation) and 44 cases in the control group (the supraclavicular nerve was not protected during operation). The incision length, operation time, intraoperative blood loss, hospital stay, visual analogue scale (VAS) pain scores before operation and 3, 6 and 12 months after operation, fracture healing at 3, 6 and 12 months after operation, and postoperative complications were recorded and compared between the 2 groups. Additionally, the number of microvessels in the middle clavicle was recorded and compared between the affected and healthy sides in 8 patients in the observation group at 6 weeks after operation.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The operation time for the observation group [(72.2±5.4) min] was significantly longer than that for the control group [(61.1±4.7) min]. The VAS scores at postoperative 3 and 6 months for the observation group [2.7 (2.4, 3.1) and 2.1 (1.9, 2.6) points] were significantly lower than those for the control group [3.5 (3.2, 3.8) and 2.7 (2.4, 2.9) points] ( P<0.05). The fracture healing rates at postoperative 3 and 6 months in the observation group [97.4% (38/39) and 100% (39/39)] were significantly higher than those in the control group [81.8% (36/44) and 86.4% (38/44)] ( P<0.05), but there was no significant difference in the fracture healing between the 2 groups at 12 months after operation ( P>0.05). At 6 weeks after operation, the number of microvessels in the middle clavicle was respectively 85.3±0.7 and 87.1±0.8 in the 8 patients in the observation group, showing no significant difference ( P>0.05). After operation, delayed incision healing occurred in 3 cases in the observation group and in 4 cases in the control group, and abnormal sensation of the skin around the incision occurred in 9 cases in the observation group and in 26 cases in the control group, showing a significant difference between the 2 groups ( P<0.05). Conclusion:Intraoperative protection of the supra-clavicular nerve is beneficial for reduction of early postoperative pain and improvement of early fracture healing, and may have a positive effect on the postoperative reconstruction of microvascular network.
