BACKGROUND: Spicy food consumption has been reported to be inversely associated with mortality from multiple diseases. However, the effect of spicy food intake on the incidence of vascular diseases in the Chinese population remains unclear. This study was conducted to explore this association. METHODS: This study was performed using the large-scale China Kadoorie Biobank (CKB) prospective cohort of 486,335 participants. The primary outcomes were vascular disease, ischemic heart disease (IHD), major coronary events (MCEs), cerebrovascular disease, stroke, and non-stroke cerebrovascular disease. A Cox proportional hazards regression model was used to assess the association between spicy food consumption and incident vascular diseases. Subgroup analysis was also performed to evaluate the heterogeneity of the association between spicy food consumption and the risk of vascular disease stratified by several basic characteristics. In addition, the joint effects of spicy food consumption and the healthy lifestyle score on the risk of vascular disease were also evaluated, and sensitivity analyses were performed to assess the reliability of the association results. RESULTS: During a median follow-up time of 12.1 years, a total of 136,125 patients with vascular disease, 46,689 patients with IHD, 10,097 patients with MCEs, 80,114 patients with cerebrovascular disease, 56,726 patients with stroke, and 40,098 patients with non-stroke cerebrovascular disease were identified. Participants who consumed spicy food 1-2 days/week (hazard ratio [HR] = 0.95, 95% confidence interval [95% CI] = [0.93, 0.97], P <0.001), 3-5 days/week (HR = 0.96, 95% CI = [0.94, 0.99], P = 0.003), and 6-7 days/week (HR = 0.97, 95% CI = [0.95, 0.99], P = 0.002) had a significantly lower risk of vascular disease than those who consumed spicy food less than once a week ( Ptrend <0.001), especially in those who were younger and living in rural areas. Notably, the disease-based subgroup analysis indicated that the inverse associations remained in IHD ( Ptrend = 0.011) and MCEs ( Ptrend = 0.002) risk. Intriguingly, there was an interaction effect between spicy food consumption and the healthy lifestyle score on the risk of IHD ( Pinteraction = 0.037). CONCLUSIONS Our findings support an inverse association between spicy food consumption and vascular disease in the Chinese population, which may provide additional dietary guidance for the prevention of vascular diseases.

Objective To test the longitudinal mediating mechanism of kinesophobia between family functioning and exercise adherence in elderly patients with postoperative adjacent vertebral re-fracture after osteoporotic vertebral compression fracture(OVCF).Methods Convenience sampling method was used to admit to the Department of Orthopaedics of a tertiary hospital in Xuzhou City with adjacent vertebral re-fracture after OVCF were conveniently selected as the survey subjects,and longitudinal investigation was conducted using the APGAR,Functional Exercise Adherence Scale,and TSK Scale.Unconditional potential growth model,structural equation and Bootstrap method were used for statistical analysis.Results A total of 232 valid questionnaires were collected.Longitudinal mediation modeling revealed that the intercept of family functioning significantly negatively predicted the intercept of kinesophobia(β=-0.456,P＜0.001)and the slope of family functioning significantly negatively predicted the slope of kinesophobia(β=-0.962,P＜0.001).The intercept for kinesophobia significantly negatively predicted the intercept for exercise adherence(β=-0.623,P＜0.001)and significantly negatively predicted the slope for exercise adherence(β=-0.354,P=0.013).Conclusion The initial level and rate of development of kinesophobia play a fully longitudinal mediating role in the development of family functioning on exercise adherence.Medical professionals should assess and manage patients'family functioning and kinesophobia in a timely manner,and rationally utilize their interrelationships to improve the level of exercise adherence as much as possible.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

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 analyze the prospective associations between liver biomarkers and mortality among Chinese middle-aged and elderly populations and to evaluate the mortality risk predictive value.Methods:A total of 22 758 participants from the 3 rd resurvey of the China Kadoorie Biobank were included. Cox proportional hazard models were used to analyze the prospective associations of 5 liver biomarkers with mortality. These liver biomarkers included two liver imaging biomarkers (liver fat attenuation parameter, liver stiffness measurement) and three serum liver enzyme biomarkers [gamma-glutamyl transferase (GGT), ALT, and AST]. Restricted cubic spline was used to assess the nonlinear associations between biomarkers and mortality. The area used the receiver operating characteristic curve (AUC) to evaluate the predictive ability of the models after incorporating liver biomarkers into traditional prediction models for mortality. Results:The mean age of the participants was (65.2±9.1) years, with a median follow-up of 1.5 years, during which 307 deaths occurred. Compared to individuals without hepatic steatosis, those with severe hepatic steatosis had a 79% higher risk of mortality, with a HR of 1.79 (95% CI: 1.06-3.03). Compared to individuals without hepatic fibrosis, those with advanced fibrosis and cirrhosis had higher mortality risks of 48% and 91%, respectively (both P<0.05). For each standard deviation increase in GGT, the mortality risk increased by 10% ( HR=1.10, 95% CI: 1.05-1.15), with the positive association plateauing at higher GGT levels. AST exhibited a U-shaped association with mortality risk. The AUC of the prediction model adding liver biomarkers into traditional prediction factors was 0.718 (95% CI: 0.679-0.757), with an increase of 0.030 ( P<0.001) compared with the traditional model. Conclusions:Severe hepatic steatosis, higher levels of hepatic fibrosis, and elevated GGT levels are significantly associated with higher mortality risk. AST shows a U-shaped nonlinear association with mortality risk. Incorporating liver biomarkers into traditional risk prediction models enhance the ability to predict mortality.

Objective:To investigate the prospective associations between plasma metabolites and the risks of all-cause and cause-specific mortality among Chinese adults.Methods:This study analyzed plasma metabolomics data from 2 183 healthy adults in the China Kadoorie Biobank (CKB), measured using targeted mass spectrometry. Cox proportional hazards regression models were used to examine the associations between 630 metabolites and the risk of all-cause mortality. Cause-specific hazard regression models evaluated the associations between metabolites and cardiovascular disease (CVD) risks, cancer, and other-cause mortality. Stepwise regression was used to identify key metabolites independently associated with all-cause mortality, and the area under the receiver operating characteristic curve (AUC) was calculated to assess the improvement in predictive performance when these metabolites were added to traditional risk prediction models.Results:The mean age of the participants was (53.2±9.8) years, 65.1% of whom were female. During a median follow-up of 14.5 years, 231 deaths occurred. A total of 44 metabolites were significantly associated with the risk of all-cause mortality [false discovery rate (FDR)-adjusted P<0.05], primarily including triglycerides, ceramides, and amino acids. Additionally, 29 and 15 metabolites were found to be associated with cancer and other-cause mortality, respectively, but no metabolites were significantly associated with CVD mortality after FDR corrections. Adding 14 metabolites independently associated with all-cause mortality into the traditional prediction model significantly improved its predictive performance. Specifically, incorporating metabolites into the traditional model, which already included laboratory biomarkers, increased the AUC to 0.798 (95% CI: 0.755-0.843), an improvement of 0.088 compared to the traditional model ( P<0.001). Conclusions:Multiple metabolites are significantly associated with mortality risk and can substantially improve the accuracy of mortality risk prediction models. These findings provide new insights into the physiological mechanisms of aging and offer valuable clues for personalized health risk assessment.

Objective To conduct a visual analysis of the research hotspots and trends of glucocorticoids in the treatment of systemic lupus erythematosus(SLE)both domestically and internationally.Methods The relevant literature from 2004 to 2024 on glucocorticoids use in SLE were retrieved in Web of Science,CNKI,WanFang Data and VIP databases.CiteSpace 6.3.R6 software was used to conduct bibliometric analysis of the number of publications,authors,research institutions,and keywords,and to draw knowledge maps.Results A total of 4,124 literature were retrieved,and 1,491 English literature and 593 Chinese literature were screened and included.The overall trend of English publications was increasing,while the number of Chinese publications declined in recent years.China is the most active country in this research field,but the research among authors and institutions was more dispersed.The results of keyword analysis showed that how to reduce the adverse reactions of glucocorticoids and special populations was the hotspots of research,with keywords such as"rheumatoid arthritis""damage""belimumab""children""pregnancy".Future research trends would be likely to focus on the assessment of treatment efficacy,prolonged remission,and reduction of disease-related injuries,with emergent keywords such as"validation""prolonged remission""treatment efficacy""renal function"Conclusion The use of glucocorticoids in the treatment of SLE continues to be the focus of the research,but with the increasing concern about adverse reactions,the research focus is gradually moving towards optimizing treatment regimens and exploring novel therapies.Future research needs to focus more on individualized treatment,long-term efficacy assessment and clinical application of emerging therapies.

Objective To explore the effectiveness of the diffusion of innovation theory in com-bination with multidisciplinary nursing collaboration in intervention for patients with severe pneumonia complicated by heart failure.Methods A total of 120 patients with severe pneumonia complicated by heart failure admitted between April 2021 and April 2024 were enrolled and randomly divided into observation group(n=60)and control group(n=60)using a random black-and-white ball method.The control group received conventional nursing intervention,while the observation group received an intervention model combining the diffusion of innovations theory with multidisciplinary collaboration on top of the conventional nursing.Rehabilitation outcomes(time to control of pulmonary inflammation,time to resolution of cough and expectoration,length of hospital stay)and post-intervention cardiac function[left ventricular ejection fraction(LVEF),left ventricular end-systolic volume(LVESV)]were compared between the two groups.The Minnesota Living with Heart Failure Questionnaire(MLHFQ)was used to assess quality of life,and the Self-Care Heart Failure Index(SCHFI)was used to evaluate self-care behaviors.Complications were compared between the two groups,and cost-effectiveness was analyzed(patient medical expenses and re-hospitalization rates).Results The observation group had shorter time to resolution of cough and expectoration,control of pulmonary inflammation,and length of hospital stay compared with the control group,with statistically significant differences(P＜0.05).After intervention,LVEF increased in both groups compared with pre-intervention lev-els,and was higher in the observation group than in the control group,with a statistically significant difference(P＜0.05);ESV decreased in both groups compared with pre-intervention levels,and was lower in the observation group than in the control group,with a statistically significant difference(P＜0.05).After intervention,physiological,emotional,and social functioning scores in the MLHFQ decreased in both groups compared with pre-intervention levels,and were lower in the ob-servation group than in the control group,with statistically significant differences(P＜0.05).After intervention,scores for self-care maintenance,self-care management,and self-care confidence in the SCHFI increased in both groups,and were higher in the observation group than in the control group,with statistically significant differences(P＜0.05).There was no statistically significant difference in the incidence of complications between the two groups(P＞0.05).Conclusion The combination of the diffusion of innovations theory and multidisciplinary collaboration nursing model can accelerate the rehabilitation process in patients with severe pneumonia complicated by heart fail-ure,improve their quality of life,and effectively enhance their self-care abilities.
