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.

Although significant progress has been made in the development of novel targeted drugs for the treatment of acute myeloid leukemia(AML)in recent years,chemotherapy still remains the mainstay of treatment and the overall survival is poor in most patients.Here,we demonstrated the antileukemia activity of a novel small molecular compound NL101,which is formed through the modification on bendamustine with a suberanilohydroxamic acid(SAHA)radical.NL101 suppresses the proliferation of myeloid malignancy cells and primary AML cells.It induces DNA damage and caspase 3-mediated apoptosis.A genome-wide clustered regularly interspaced short palindromic repeats(CRISPR)library screen revealed that phosphatase and tensin homologous(PTEN)gene is critical for the regulation of cell survival upon NL101 treatment.The knockout or inhibition of PTEN significantly reduced NL101-induced apoptosis in AML and myelodysplastic syndrome(MDS)cells,accompanied by the activation of protein kinase B(AKT)signaling pathway.The inhibition of mammalian target of rapamycin(mTOR)by rapamycin enhanced the sensitivity of AML cells to NL101-induced cell death.These findings uncover PTEN protein expression as a major determinant of chemosensitivity to NL101 and provide a novel strategy to treat AML with the combination of NL101 and rapamycin.

At present, interdisciplinary integration has become a major feature of the development of science and technology, and multi-disciplinary integration will gradually become the norm. Professional and technological multi-disciplinary integration has unpredictable potential, which will produce new disciplinary frontiers, new fields of science and technology and new patterns of innovation. Organ donation is a new discipline in China's new era. Constructing and promoting an organ donation disciplinary system with the overall goal of safeguarding legal and reasonable rights and interests of donors and their families and the health rights and interests of the recipients are in line with the fundamental requirements of maintaining high-quality development of organ donation and transplantation in China. Meantime, organ donation is a complex medical and social behavior, and organs donated by citizens belong to national resources, which also endows organ donation with a social welfare attribute and relevance with all parties in society. In this article, the essence of current problems encountered during organ donation in China, the whole process of organ donation and theoretical knowledge, professional skills and personnel support required by donors in different clinical stages were analyzed to illustrate the necessity and feasibility of establishing an organ donation disciplinary system based on multi-disciplinary integration. Besides, how to integrate organ donation disciplinary construction into the national policy was also investigated. Taking safeguarding the rights and interests of donors, family members and recipients as the core and taking organ donation and transplantation as the main line, cooperative principles of co-creation, co-construction, mutual promotion, sharing and win-win should be upheld, aiming to promote multi-disciplinary integration and comprehensive talent cultivation of organ donation, jointly enhance the recognition rate and donation rate of organ donation, and make organ donation widely recognized by citizens from all walks of life.

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.

Objective:To observe the effect of sagittal traction on the internal fixation with proximal femoral nail anti-rotation (PFNA) for femoral intertrochanteric fractures in the elderly patients.Methods:A retrospective study was conducted to analyze the clinical data of 61 elderly patients with intertrochanteric fracture who had been treated from January 2016 to January 2018 at Department of Orthopaedics, The Ninth Hospital of Ningbo. Of them, horizontal traction of the affected limb was performed in 31 (16 males and 15 females with an age of 73.6 years ± 9.4 years) while 10°-20° sagittal traction of the affected limb in 30 (15 males and 15 females with an age of 75.0 years ± 7.2 years). The 2 groups were compared in terms of operation time, intraoperative blood loss, times of intraoperative fluoroscopy, fracture healing time, hip function at 6 months after operation by Harris scoring and complications.Results:There was no statistically significant difference between the 2 groups in the general clinical data, showing comparability ( P>0.05). The operation time (47.1 min ± 4.7 min), intraoperative blood loss (72.3 mL ± 9.1 mL), and times of intraoperative fluoroscopy (11.5 ± 1.4) in the sagittal traction group were significantly less than those in the horizontal traction group (56.7 min ± 4.6 min, 103.9 mL ± 19.2 mL, and 14.6±1.6) ( P< 0.05). This cohort was followed up for 6 to 18 months (12.6 months on average). There were no significant differences between the 2 groups in quality of postoperative fracture reduction, fracture healing time or hip Harris scores at postoperative 6 months ( P>0.05). Internal fixation loosening and hip pain occurred in one patient in the sagittal traction group. Follow-ups observed no complications like wound infection, bedsores, deep vein thrombosis or hip varus deformity in either group. Conclusion:As 10°-20° sagittal traction can lift the affected limb upward to avid blockage by the iliac wing, hip soft tissue and lateral abdominal wall, it lends convenience to surgeons, reducing intraoperative bleeding volume, times of fluoroscopy and operation time.

Objective:To investigate the triggering factors of ischemic stroke and their correlation with stroke severity and traditional risk factors.Methods:The clinical data of patients with ischemic stroke within 2 weeks of the onset were collected retrospectively. They were divided into two groups according to the questionnaire of triggering factors. The demographic and baseline data of the two groups were compared. According to the National Institutes of Health Stroke Scale (NIHSS) score, the patients were divided into low NIHSS score group (≤8) and high NIHSS score group (>8). The demographic and baseline data were compared. Multivariate logistic regression analysis was used to determine the independent related factors of the existence of triggering factors in patients with ischemic stroke and the correlation between the existence of triggering factors and the severity of stroke. Results:A total of 217 patients were enrolled in the study. Their age was 63.4±12.8 years and 148 were male (68.2%). One hundred and nine patients had at least one triggering factor. Common triggering factors were sleep disorders (46.8%), infection (18.4%), and missed medication (13.8%). Multivariate logistic regression analysis showed that after adjusting for confounding factors, diabetes mellitus (odds ratio [ OR]2.496, 95% confidence interval [ CI]1.347-4.626; P=0.047), large artery atherosclerosis ( vs. small vessel occlusion: OR 2.168, 95% CI 1.060-4.343; P=0.034) and baseline NIHSS score (the fourth quartile vs. the first quartile: OR 2.320, 95% CI 1.043-5.162; P=0.039) were independently associated with the existence of triggering factors in patients with ischemic stroke, and any of the triggering factors was independently associated with stroke severity ( OR 2.042, 95% CI 1.106-3.770; P=0.023). Conclusion:Diabetes and the severity of stroke are associated with the existence of triggering factors in patients with ischemic stroke. Stroke severity in ischemic stroke patients with triggering factors is more severe.
