Objective:To explore the application value of head-mounted display (HMD) devices in endoscope-assisted breast augmentation surgery.Methods:This prospective study enrolled female patients who underwent breast augmentation at the Department of Plastic Surgery, Tianjin Meilai Medical Cosmetology Hospital from March to December 2024. According to admission time, patients were divided into a control group and an observation group. The control group underwent endoscope-assisted breast augmentation, while the observation group received the same procedure with the addition of an HMD device. Six surgeons compared the two groups in terms of operative time, intraoperative blood loss, visual analogue scale (VAS) scores at different time points, general comfort questionnaire (GCQ) scores, surgeons’ subjective evaluation scale scores, incidence of postoperative complications, and overall postoperative satisfaction rate based on patients’ subjective evaluations. Measurement data were analyzed by independent-samples t-test, and count data were analyzed by chi-square ( χ2) test. A P-value <0.05 was considered statistically significant. Results:A total of 60 female patients were included, with 30 cases in each group. Operative time and intraoperative blood loss were lower in the observation group than in the control group [(68.2±11.0) min vs. (76.3 ±13.6) min; (40.1±7.3) ml vs. (49.3±8.6) ml; both P<0.05]. Preoperative VAS scores showed no significant difference between the two groups [(7.88 ±1.28) points vs. (7.85 ±1.23) points, P> 0.05]. At 12 h and 24 h postoperatively, VAS scores in the observation group were significantly lower than those in the control group [(5.7 ±1.1) points vs. (6.4 ±1.2) points; (4.5 ±1.0) points vs. (5.3±1.0) points; both P<0.05]. Preoperative GCQ scores showed no significant difference [(9.6±2.2) points vs. (9.6±2.2) points, P>0.05], while postoperative GCQ scores and surgeons’ subjective evaluation scores were higher in the observation group [(16.3±3.8) points vs. (13.2 ±2.7) points; (89.7 ±11.6) points vs. (82.7 ±10.6) points; (90.3±10.5) points vs. (83.0±12.0) points; all P<0.05]. Regarding postoperative complications, the incidence of postoperative bleeding was higher in the control group [13.3% (4/30) vs. 0 (0/30), P <0.05], while the differences in hematoma (6.7% vs. 3.3%), poor incision healing (10.0% vs. 6.7%), and implant displacement (10.0% vs. 6.7%) were not statistically significant (all P>0.05). The postoperative satisfaction rate was 96.7% (29/30) in the observation group and 76.7% (23/30) in the control group, with no statistically significant difference ( P>0.05). Conclusion:The introduction of HMD devices in endoscope-assisted breast augmentation surgery can effectively expand the visualization of the operative field, shorten operative time, reduce intraoperative blood loss, alleviate early postoperative pain, and improve the surgeon’s intraoperative convenience.

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.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

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.

This study was aimed at exploring the prevalence and drug sensitivity of Gordonia strains isolated from sputum samples in Henan Province,to provide data to aid in the prevention and treatment of Gordonia infection.A combination of 16S rDNA and sec A1 gene sequencing was used to identify the isolated strains,and susceptibility to16 drugs was determined with the broth microdilution method.A total of 21 strains were identified through 16S rDNA gene and sec A1 gene sequencing,including five strains of Gordonia broncians,eight strains of Gordonia paraphernivans,seven strains of Gordonia sputi,and one strain of Gordonia aichiensis.Drug sensi-tivity testing showed high Gordonia sensitivity to drugs such as ceftriaxone,linezolid,doxycycline,amoxicillin/clavulanic acid,mino-cycline,cefotaxime,trimethoprim/sulfamethoxazole,imipenem,tobramycin,and clarithromycin.The sensitivity rates of the isolated strains were 90.48%(19/21),100%(21/21),90.48%(19/21),90.48%(19/21),95.24%(20/21),90.48%(19/21),90.48%(19/21),90.48%(19/21),and 95.24%(20/21),respectively.Gordonia showed high resistance to rifampicin and cefepime,with rates of 28.57%(6/21)and 19.05%(4/21),respectively.Meanwhile,the resistance varied among bacterial strains.The resistance rate of G.sputi to rifampicin reached 71.43%(5/7),whereas that of G.parapffinivoras to cefepime was 37.5%(3/8).The main species of Gordo-nia isolated from sputum samples of patients in Henan Province were G.bronchialis,G.paraffinivoras,G.sputi,and G.aichiensis.Drug sensitivity tests indicated that drugs including amoxicillin/clavulanic acid,ceftriaxone,cefotaxime,tobramycin,clarithromycin,mi-nocycline,trimethoprim/sulfamethoxazole,linezolid,and doxycycline had good antibacterial effects against Gordonia.
