Objective The present study aims to explore the mediating role of rumination and coping styles in social support and post-traumatic stress disorder(PTSD)in young and middle-aged spinal cord injury(SCI)patients.The study will provide a basis for developing targeted interventions.Methods Two hundred and forty young and middle-aged SCI patients hospitalized for treatment were selected by convenience sampling and questionnaires were administered using the General Information Questionnaire,the Perceived Social Support Scale(PSSS),the Simplified Coping Style Questionnaire(SCSQ),the Event Related Rumination Inventory(ERRI),and the Post-traumatic Stress Disorder Self-assessment Scale(PCL-C),Mediation analysis using Model-6 with Process4.1 plugin in SPSS 25.0.Results The mean scores for PTSD,social support,rumination,positive coping,and negative coping in young and middle-aged SCI patients were 29.00(26.00,35.75),67.00(62.00,70.00),and 37.00(34.00,4 1.00),and 36.00(33.00,42.00),respectively.PTSD demonstrated a negative correlation(r=-0.553,r=-0.484,P＜0.001)and a negative correlation with positive coping and rumination(r=0.499,r=0.472,P＜0.001).The mediation modelling test demonstrated that rumination and positive and negative coping mediated significantly between social support and PTSD,with effect values of-0.078 1,-0.097 0 and-0.049 6,accounting for 17.81％,22.12％and 11.31％of the total effect,respectively.Furthermore,the chain mediation effects of rumination and positive coping and negative coping were also significant,with effect values of-0.026 3 and-0.026 2,accounting for 5.99％and 5.97％of the total effect,respectively.Conclusions The present study hypothesises that rumination,thinking and coping styles play a simple and chain-mediating role between social sup-port and PTSD in young and middle-aged SCI patients.Medical professionals should focus on the mediating role of rumination and coping styles when developing interventions related to improving and preventing PTSD in patients,which can be done by increasing the level of social support for patients,decreasing the level of rumination,and guiding patients to positively cope with their illness.

Objective:To investigate the clinical significance of elevated cytokeratin 19 fragment (CYFRA21-1) in patients with dermatomyositis associated with positive anti-melanoma differentiation-associated gene 5 (MDA5) antibody.Methods:142 consecutive cases with newly onset anti-MDA5(+) (MADEDM)-DM admitted to the first affiliated hospital of Zhengzhou University from June 2018 to October 2021 were enrolled. They were divided into two groups, the low serum CYFRA21-1 group (CYFRA21-1≤4 ng/ml) and the high serum CYFRA21-1 group (CYFRA21-1>4 ng/ml). The clinical manifestations, laboratory tests results, imaging examinations treatment and outcome were collected for statistical analysis. Enumeration data were expressed as the number of cases and percentage (%). Normally distributed parameters were tested by t-test. Parameters with skewed distribution were tested by Mann-Whitney Wilcoxon analysis. Categorical variables were compared by the Chi-square test or Fisher′s exact test. Risk factor analysis was performed using Logistic regression. Cumulative survivals were described by Kaplan-Meier curves. Results:The age of onset in the high CYFRA21-1 group [(56±9)years vs. (50±10) years, t=-3.50, P=0.001] was higher than that in the low CYFRA21-1 group. Fever [63.3% (38/60) vs. 40.2% (33/82), χ2=7.39, P=0.007] was more common in the high CYFRA21-1 group, and arthritis [41.7% (25/60) vs. 69.5%(57/82), χ2=11.01, P=0.001] was less common. Myalgia, myasthenia, rashes, Raynaud′s phenomenon and skin ulcers had no significant difference between the two groups. The WBC count [5.2(4.1, 6.9)×10 9/L vs. 4.3(3.2, 6.2)×10 9/L, Z=-2.57, P=0.010], neutrophil count [4.0(2.9, 5.5)×10 9/L vs. 2.9(2.1, 4.5)×10 9/L, Z=-3.25, P=0.001] and neutrophil/lymphocyte ratio [5.75(3.50, 9.20) vs. 3.55(2.64, 5.41), Z=-3.77, P<0.001] in high CYFRA21-1 group were significantly higher than those in low CYFRA21-1 group. At the same time, LDH [384(302, 519)U/L vs. 318(260, 405)U/L, Z=-2.98, P=0.003], ferritin [1 204(677, 2 039)ng/ml vs. 570(229, 846)ng/ml, Z=-4.78, P<0.001], KL-6 [995(658, 1 491)U/ml vs. 750(563, 1 197)U/ml, Z=-2.49, P=0.013], ESR [36(22, 61)mm/1 h vs. 28(15, 46)mm/1 h, Z=-2.18, P=0.029] and CRP [9.2(4.7, 31.5)mg/L vs. 3.1(1.1, 11.6)mg/L, Z=-3.53, P<0.001] were significantly increased in the high level of CYFRA21-1 group, while serum albumin[(32±5)g/L vs. (35±5)g/L, t=3.92, P<0.001] was significantly decreased. There was no significant difference in the titers of serum anti-MDA5 antibodies between the two groups. The positive rate of anti-RO52 antibody [44(74.6%) vs. 44(53.7%), χ2=6.40, P=0.011] in high CYFRA21-1 group was higher than that in low CYFRA21-1 group. The ground glass opacity (GGO) score [1.75(1.33, 2.42) vs. 1.09(0.67, 1.67), Z=-4.60, P<0.001] based on high resolution CT (HRCT) was also significantly increased in the CYFRA21-1 high level group. Compared with the low CYFRA21-1 group, the high CYFRA21-1 group had a higher probability of RP-ILD [48.3%(29/60) vs. 23.2%(19/82), χ2=9.80, P=0.002] and a higher 6-month mortality rate[48.3%(29/60) vs.13.4%(11/82), χ2=19.70, P<0.001]. Logistic regression analysis showed that age ≥53 years old [ OR(95% CI)=5.197(1.781, 15.165), P=0.003], duration < 2 months [ OR(95% CI)=3.314 (1.058, 10.378), P=0.040], NE/LYMP >5 [ OR(95% CI)=3.443(1.120, 10.586), P=0.031], CRP>5 mg/L[ OR(95% CI)=6.271(1.749, 22.480), P=0.005], CA125>14 U/ml[ OR(95% CI)=7.500 (2.409, 23.345), P=0.001] and CYFRA21-1>4 ng/ml[ OR(95% CI)=3.665(1.258, 10.676), P=0.017] were independent risk factors for death within 6 months in MDA5-DM patients. Kaplan-Meier survival curve showed that the survival rate of the high CYFRA21-1 group was significantly lower than that of the low CYFRA21-1 group( P<0.001). Conclusion:Elevated CYFRA21-1 is an independent risk factor for early mortality in MDA5-DM patients and can serve as a novel serological marker for risk stratification in these patients.

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.

BACKGROUND: The FAVOR (Comparison of Quantitative Flow Ratio Guided and Angiography Guided Percutaneous Intervention in Patients with Coronary Artery Disease) III China trial demonstrated that percutaneous coronary intervention (PCI) lesion selection using quantitative flow ratio (QFR) measurement, a novel angiography-based approach for estimating fractional flow reserve, improved two-year clinical outcomes compared with standard angiography guidance. This study aimed to assess the cost-effectiveness of QFR-guided PCI from the perspective of the current Chinese healthcare system. METHODS: This study is a pre-specified analysis of the FAVOR III China trial, which included 3825 patients randomized between December 25, 2018, and January 19, 2020, from 26 centers in China. Patients with stable or unstable angina pectoris or those ≥72 hours post-myocardial infarction who had at least one lesion with a diameter stenosis between 50% and 90% in a coronary artery with a ≥2.5 mm reference vessel diameter by visual assessment were randomized to a QFR-guided strategy or an angiography-guided strategy with 1:1 ratio. During the two-year follow-up, data were collected on clinical outcomes, quality-adjusted life-years (QALYs), estimated costs of index procedure hospitalization, outpatient cardiovascular medication use, and rehospitalization due to major adverse cardiac and cerebrovascular events (MACCE). The primary analysis calculated the incremental cost-effectiveness ratio (ICER) as the cost per MACCE avoided. An ICER of ¥10,000/MACCE event avoided was considered economically attractive in China. RESULTS: At two years, the QFR-guided group demonstrated a reduced rate of MACCE compared to the angiography-guided group (10.8% vs . 14.7%, P <0.01). Total two-year costs were similar between the groups (¥50,803 ± 21,121 vs . ¥50,685 ± 23,495, P = 0.87). The ICER for the QFR-guided strategy was ¥3055 per MACCE avoided, and the probability of QFR being economically attractive was 64% at a willingness-to-pay threshold of ¥10,000/MACCE avoided. Sensitivity analysis showed that QFR-guided PCI would become cost-saving if the cost of QFR were below ¥3682 (current cost: ¥3800). Cost-utility analysis yielded an ICER of ¥56,163 per QALY gained, with a 53% probability of being cost-effective at a willingness-to-pay threshold of ¥85,000 per QALY gained. CONCLUSION: In patients undergoing PCI, a QFR-guided strategy appears economically attractive compared to angiographic guidance from the perspective of the Chinese healthcare system.

Objective:To construct an evidence-based practice program for dietary management of patients with non-dialysis chronic kidney disease (CKD) based on best evidence and to evaluate the effectiveness of its application.Methods:The best evidence for dietary management of non-dialysis CKD patients was summarized. From September to October 2022, following the evidence clinical transformation model of the Fudan University Centre for Evidence-based Nursing, the best evidence was screened and evidence-based practice program were developed, taking into account patients' wishes, expert opinions, and clinical contexts. From November 2022 through March 2023, baseline reviews, analysis of barriers and facilitators were implemented. Between April 2023 and April 2024, evidence-based practice was carried out in the Department of Nephrology of the Second Affiliated Hospital of Guangzhou Medical University to compare the implementation rate of review indicators at the system, practitioner, and patient levels, and practitioners' knowledge before and after the application of evidence.Results:A total of 14 review indicators were developed. The implementation rate of the 12 review indicators and the practitioners' knowledge of the CKD diet were elevated after the evidence-based practice ( P<0.05) . Conclusions:Evidence-based practice program for dietary management of patients with non-dialysis CKD has a positive effect on improving practitioners' knowledge of non-dialysis CKD diets, implementation rate of dietary management behaviors, and patients' dietary behaviors.
