Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective:To explore the impact of metabolic syndrome in conjunction with hyperuricemia on the risk of new-onset cardiovascular disease.Methods:This study was a prospective cohort study. From June 2006 to October 2007, employees of Kailuan Group in Tangshan City, Hebei Province were selected as the research subjects. Participants were divided into four groups based on the presence or absence of metabolic syndrome and hyperuricemia. The groups include the normal group, pure hyperuricemia group, pure metabolic syndrome group, and the metabolic syndrome combined with hyperuricemia group. Four groups of participants were followed up, the primary endpoint was the occurrence of a first-ever cardiovascular disease event, including stroke and myocardial infarction. The cumulative incidence rates of cardiovascular disease in different groups during the continuous follow-up period were calculated using the Kaplan-Meier method, and the differences in cumulative incidence rates among groups were compared using the log-rank test. Multivariate Cox regression analysis was used to analyze the effect of hyperuricemia combined with metabolic syndrome on the risk of cardiovascular disease. The likelihood ratio test was used to analyze whether there was a multiplicative interaction and additive interaction between hyperuricemia and metabolic syndrome.Results:A total of 82 780 individuals were included, aged (51.5±12.6) years, and 68 622 (82.90%) were males, with a median follow-up of 14.97 years. Kaplan-Meier survival curve analysis showed that the cumulative incidence of cardiovascular disease was the highest in the metabolic syndrome combined with hyperuricemia group (log-rank P<0.001). Multivariate Cox regression analysis indicated that after adjusting for various confounding factors, the HR value and 95% CI of cardiovascular disease in the metabolic syndrome combined with hyperuricemia group were 1.24 (1.12-1.38) compared with the normal group, which were higher than those in the pure hyperuricemia group and the pure metabolic syndrome group alone. The effect of metabolic syndrome combined with hyperuricemia on the risk of cardiovascular disease demonstrated an additive effect (relative excess risk of interaction: 0.18(0.11-0.25), attributable proportion due to interaction: 0.14(0.09-0.19)). Conclusions:The combination of hyperuricemia and metabolic syndrome is an independent risk factor for cardiovascular disease. Compared to pure metabolic syndrome or hyperuricemia alone, the impact of metabolic syndrome combined with hyperuricemia on cardiovascular disease is more significant.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To analyze the exposure level and changes in severe respiratory infection among Chinese residents aged ≥40 years in China and to provide essential data for preventing and controlling chronic respiratory diseases.Methods:The data came from chronic obstructive pulmonary disease surveillance of Chinese residents in 2014-2015 and 2019-2020. The surveillance covers 31 provinces (autonomous regions and municipalities) in China. A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥40 years. Relevant information about exposure to severe respiratory infections during childhood was collected through investigation. Rigorous complex sampling and weighted analysis were applied to estimate the exposure rate of severe respiratory infections among children with different characteristics among residents aged ≥40 years in China from 2019 to 2020. Additionally, changes in severe respiratory infections during childhood were analyzed over 2014-2015 and 2019-2020.Results:In 2019-2020, the exposure rate of severe respiratory infection before 18 for residents aged ≥40 years in China was 21.58‰ (95% CI: 17.57‰-25.59‰). The exposure rate of severe respiratory infection before the age of 14 was 19.40‰ (95% CI:15.25‰-23.55‰), the difference in the exposure rate between men and women was not statistically significant (both P>0.05), and the exposure rate of urban residents is higher than that of rural residents. The results of multivariate logistic regression analysis showed that in western rural areas, factors including being born by cesarean section, exposure to secondhand smoke before age 14 years old, and a family history of chronic respiratory diseases were associated with severe respiratory infections in childhood. Compared with 2014-2015, the proportion of residents aged 40 and older in China hospitalized for pneumonia or bronchitis before 14 from 2019 to 2020 was slightly lower than five years prior. Conclusions:Among residents in China aged ≥40 years, 21.58‰ experienced severe respiratory infection exposure during childhood, varying exposure levels across different demographic groups. The burden of chronic respiratory diseases in adulthood cannot be ignored. Efforts should be made to expand the coverage of planned immunization and to focus on early-life interventions during childhood to reduce the incidence of severe respiratory infections.
