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 evaluate the clinical outcome of neurosurgical robot-assisted stereotactic puncture and drainage for brain abscess.Methods A retrospective analysis was conducted on the clinical data of 53 patients with brain abscess admitted to our hospital from January 2018 to December 2024.Among them,29 cases underwent craniotomy for abscess resection(craniotomy group),while 24 cases received neurosurgical robot-assisted stereotactic puncture and drainage(robot-assisted group).The operation time,intraoperative blood loss,decompressive craniectomy rate,proportion of postoperative antibiotic regimen adjustment,postoperative hospital stay,incidence of postoperative complications,mortality rate and Glasgow outcome scale(GOS)scores 6 months after surgery of patients were compared between the two groups.Results Compared with the craniotomy group,the robot-assisted group demonstrated significantly shorter operation time,less intraoperative blood loss,and lower incidence of postoperative complication,the differences were all statistically significant(P<0.05).However,there were no statistically significant differences in terms of decompressive craniectomy rate,postoperative hospital stay,mortality rate,GOS score,or proportion of the postoperative antibiotic regimen adjustment between the two groups(P>0.05).Conclusion As a precise and minimally invasive surgical method,neurosurgical robot-assisted stereotactic puncture and drainage for patients with brain abscess can effectively improve the operational efficiency,shorten the operation time,reduce intraoperative injury,and lower the risk of postoperative complications.It has high clinical application value and potential for widespread adoption.

Objective:To evaluate the effect of 5th generation mobile communication technology(5G) remote robot-assisted cholecystectomy on postoperative recovery and quality of life in patients with gallstones.Methods:Clinical data of patients who underwent 5G remote robotic cholecystectomy(20 cases) vs traditional robotic cholecystectomy(20 cases) at Gansu Provincial People's Hospital from May to September 2023 were retrospectively analyzed. Intraoperative and postoperative related indexes were compared between the two groups, and changes in pain analog scores before, 12 hours, and 24 hours after surgery, and global quality of life (GIQLI) scores before and 3 months after surgery were evaluated.Results:There was no significant difference between the two groups in terms of intraoperative and postoperative conditions (intraoperative blood loss, operative time, time to exhaustion, and length of hospital stay). Patients' pain analog scores at 12 and 24 hours postoperatively were lower than preoperatively, but the differences were not statistically significant( P>0.05). In addition, there was no significant difference in recovery indicators between the two groups compared to the control group ( P>0.05). Conclusion:The postoperative recovery metrics of 5G tele-robotic-assisted cholecystectomy were consistent with the results of conventional robotic surgery.

Objective:To evaluate the clinical efficacy of botulinum toxin type A (BTX-A) combined with sodium hyaluronate solution for facial microdroplet injection in improving facial skin photoaging.Methods:A prospective randomized controlled trial was conducted. From January to July 2024, patients with facial photoaging problems were recruited from the Plastic Surgery Department of the Affiliated Hospital of Xuzhou Medical University and randomly divided into a monotherapy group (sodium hyaluronate solution droplet injection) and a combination therapy group (BTX-A + sodium hyaluronate solution droplet injection) by hierarchical block randomization method. The treatment regimen was 3 months, with one treatment for each month, with a total of 3 treatment. The combination therapy group only used a combination therapy of two drugs (BTX-A 25 U+ 5 ml sodium hyaluronate solution) during the first injection. During the three treatments of the monotherapy group and the second and third treatments of the combination therapy group, 5 ml of sodium hyaluronate solution was injected as the solo ingredient. Follow up was conducted at 1, 2, and 4 months after the last treatment. Serum superoxide dismutase (SOD) activity and malondialdehyde (MDA) levels were detected by test kit. Five skin texture indicators (moisture content, transepidermal water loss rate, elasticity, glossiness, and pH) were evaluated using the German CK skin tester. VISIA skin detector was used for facial two-dimensional photography and skin condition analysis. Clinical efficacy (significant improvement, obvious improvement, improvement, no improvement) and global aesthetic improvement scale (GAIS) scores on a 5-point scale were recorded. Patient satisfaction levels (very satisfied, satisfied, and dissatisfied) were investigated. The data were analyzed using SPSS 27.0 software. Count data was presented as examples and(or) percentages, and analyzed using a chi-square test. Normal distribution measurement data was represented by Mean±SD and analyzed using t-test. Results:A total of 100 patients were included, with 50 cases in each group. There were 17 males and 33 females in the monotherapy group, with an age of (31.3±7.1) years, and there were 5, 14, 29 and 2 patients in the Ⅰ to Ⅳ types of Glogau skin photoaging classification, respectively. There were 15 males and 35 females in the combination therapy group, with an age of (32.1±8.4) years old, and there were 4, 15, 27 and 4 patients in the Ⅰ to Ⅳ types of Glogau skin photoaging classification, respectively. There was no statistically significant difference in gender composition, age, and Glogau skin photoaging classification between the two groups (all P>0.05). One month after the first treatment, both groups showed an increase in SOD activity and a decrease in MDA levels, with more significant changes observed in the combination therapy group ( P<0.01 for both). At the follow-up of 1, 2, and 4 months after the last treatment, the combination therapy group outperformed the monotherapy group in all 5 skin texture indicators (all P<0.05). One month after the last treatment, the total effective rate of the combination therapy group was 76.0% (38/50), which were significantly higher than that of the monotherapy group’s 50.0% (25/50) ( P<0.05); in addition, the combination therapy group showed significant advantages in facial aesthetic GAIS scores, as well as patient satisfaction, with a satisfaction rate of up to 98.0% (49/50), which was higher than the 88.0% (44/50) of the monotherapy group ( P<0.01). Throughout the entire treatment process, neither group experienced serious adverse reactions. Conclusion:Facial microdroplet injection of BTX-A combined with sodium hyaluronate solution effectively improves symptoms of facial skin photoaging, enhancing skin hydration and elasticity, reducing transepidermal water loss, improving skin gloss, regulating skin pH, and enhancing skin antioxidant capacity, ultimately achieving facial skin rejuvenation. This method is safe, effective and holds high clinical relevence and patient satisfaction.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Background and purpose:According to the latest data from the National Cancer Center,the incidence rate and mortality of lung cancer in China rank first among all malignant tumors,and 85%are non-small cell lung cancer(NSCLC).In recent years,immunotherapy based on programmed cell death protein-1(PD-1)/programmed death ligand-1(PD-L1)immune checkpoint inhibitors(ICIs)has made breakthrough progress in lung cancer,bringing more survival benefits to lung cancer patients.This study aimed to evaluate the cost-effectiveness of three major PD-L1 testing assays in guiding immunotherapy for patients with NSCLC,and to provide empirical evidence to guide the selection of cost-effective diagnosis and ICIs monotherapy regimens for NSCLC patients in China.Methods:From a healthcare system perspective,a decision-tree model was constructed to simulate the cost and effectiveness(percentage of the patients who were successfully diagnosed and who were correctly prescribed and underwent correct treatment according to China treatment guidelines)of employing Ventana PD-L1 IHC(SP263)assay,PD-L1 IHC 22C3 pharmDx,and Dako 22C3 antibody concentrate in early to mid-stage and advanced NSCLC patients in China,respectively.The cost-effectiveness of SP263 assay compared to other testing methods was assessed through the incremental analysis.The robustness of the base case analysis results was validated by using one-way sensitivity analysis and probabilistic sensitivity analysis.Results:When considering atezolizumab monotherapy following chemotherapy for early to mid-stage(Ⅱ A-Ⅲ B)NSCLC patients,in comparison to the 22C3 assay or 22C3 antibody concentrate,the SP263 assay incurred an additional cost of 9 449 yuan per successfully diagnosed and treated patient.The SP263 assay,which can guide multiple ICIs monotherapies(e.g.,atezolizumab,pembrolizumab)for advanced(Ⅳ)NSCLC patients,was dominant by achieving a higher percentage of successfully diagnosed and treated patients at a lower cost compared to Dako 22C3 assay and Dako 22C3 antibody concentrate.One-way sensitivity analysis and probabilistic sensitivity analysis both confirmed the robustness of the results.Conclusion:The Ventana PD-L1 IHC SP263 assay was cost-effective,compared to Dako PD-L1 IHC 22C3 assay and Dako 22C3 antibody concentrate for the immunotherapy treatment for both stage Ⅱ A-Ⅲ B and stage Ⅳ NSCLC patients in China.
