Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM_2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Objective:To investigate the clinical efficacy and safety of ultrasonic bone scalpel in nasal osteotomy.Methods:A retrospective analysis was conducted on clinical data from the patients who received ultrasonic bone scalpel-assisted nasal osteotomy in the Nasal Plastic & Reconstructive Surgery Department, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College between January 2023 and April 2024. All patients underwent open lateral approach osteotomy using an ultrasonic bone scalpel under direct vision, combined with augmentation rhinoplasty using autologous costal cartilage grafting. Intraoperatively, the nasal dorsum was fully exposed, and the lateral nasal cartilage was separated from the nasal septum, followed by precise bone tissue incision using the ultrasonic bone scalpel. Parameters recorded included operative time, and postoperative complications. Based on the standardized photographs taken before the operation and during the 6-month follow-up after the operation, the observer global aesthetic improvement scale (GAIS) was evaluated by a third-party doctor, with a score ranging from 1 to 5. The smaller the score, the more significant the improvement compared to before the operation. The satisfaction of patients with the surgical outcome was evaluated and classified into four levels: very satisfied, satisfied, dissatisfied, and very dissatisfied.Results:A total of 25 female patients were enrolled, aged 20 to 38 years, with an average age of 27.1 years. All procedures were completed successfully, with a mean operative time of (25.4±4.2) minutes. Postoperative localized swelling of varying degrees was observed. Follow-up ranged from 6 to 18 months, with nasal contour and curvature stabilizing by 6 months postoperatively. No complications, such as infection, nasolacrimal duct, lacrimal sac, medial canthal ligament, nerve injuries, or sensory disturbances, were reported. Two cases exhibited mild nasal bone widening at the 6-month follow-up, though no surgical revision was requested. Significant improvement in external nasal morphology was achieved in all patients, with high satisfaction rates. The patients satisfaction survey showed that 18 cases (72%) were very satisfied and 7 cases (28%) were satisfied with the surgical outcome. GAIS scores reflected positive evaluations [(1.24±0.51) points].Conclusion:The ultrasonic bone scalpel for nasal osteotomy offers the advantages of high-precision cutting and efficient hemostasis. It is highly effective in reshaping the nasal contour, with shorter osteotomy time, reduced intraoperative bleeding, and a lower postoperative complication rate. This study provides some insights into plastic surgeons in optimizing nasal bone modification strategies.

Objective It aims to systematically review the concept of hospital digital maturity and its application in the digital transformation of hospitals,analyzes existing digital maturity assessment models internationally,and examine relevant research progress to provide reference and support for the digital transformation of Chinese hospitals.Methods By using the systematic review method,a systematic review was conducted by searching rele-vant literature in both Chinese and English databases,including CNKI,Wanfang Database,PubMed,Medline,and Web of Science.Keywords used for the search included digital maturity,digital capability,health,and hospital.Results Widely used international digital maturity assessment models encompass various dimensions,such as organizational management,digital technology capabilities,healthcare professional digital capabilities,data analytics,and interoperability.Some countries have applied these models in the digital transformation practices of hospitals,while attention to this field remains relatively limited in China.Conclusion Digital maturity assessment is a crucial tool for promoting the digital transformation of hospitals;however,existing evaluation frameworks are not directly appli-cable to China's public hospital system.Future research should focus on developing quantifiable assessment tools tai-lored to the characteristics of Chinese public hospitals,thereby promoting hospital digital transformation and high-quality development.

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 evaluate the changes of carotid intima thickness（CIT）and stiffness parameters in ankylosing spondylitis（AS）patients by 24 MHz ultra-high frequency ultrasound probe and RF-data based quantitative analysis on vessel stiffness（R-VQS），and to explore its influencing factors.Methods:Sixty patients with AS who underwent consultation at Henan Provincial People's Hospital from November 2023 to May 2024 were prospectively collected as AS group，54 healthy volunteers matched for sex，age，and body mass index were collected as control group. CIT were measured using a 24 MHz ultra-high frequency ultrasound probe，hardness coefficien（HC）and pulse wave velocity（PWV）were measured by R-VQS，the differences of the parameters between the two groups were compared. The changes of carotid artery elasticity and intima thickness and their influencing factors in patients with AS were explored by univariate and multivariate linear regression analysis.Results:①C-reactiveprotein，erythrocyte sedimentation rate（ESR），neutrophil count and neutrophil to lymphocyte ratio（NLR）were elevated in the AS group compared with the control group，and the differences were statistically significant（all P < 0.05）. ②CIT，carotid intima-media thickness（CIMT），HC，PWV and epicardial adipose tissue thickness（EATT）were all increased in the AS group compared with the control group，and the differences were statistically significant（all P < 0.05）. ③Multifactorial linear regression analysis showed that EATT，ESR were the main influencing factors of HC，PWV and CIT（ β=2.192，0.031；1.792，0.002；0.097，0.001；all P＜0.05）. Conclusions:Carotid CIT，CIMT，HC，PWV and EATT are all higher in the AS patients，and ESR and EATT are the main influencing factors of HC，PWV，and CIT，suggesting that more attention should be paid to the detection of ESR and EATT in patients with AS when interventions are performed clinically.

Objective To investigate the influence of oxygen supply flow rate in high-flow nasal cannula(HFNC)oxygen therapy on pressure distributions in the upper airway.Methods A three-dimensional(3D)model of the upper airway was reconstructed using CT images from an adult male,and then coupled with a high-flow nasal cannula model to establish a coupled model of the nasal cannula and the upper airway.Subsequently,a physical model of this upper airway,which was combined with a head model,artificial lungs,and a monitoring system was created by 3D printing technology to form a physical simulation platform in vitro.Computational and physical simulations were carried out respectively to determine the air pressure at typical locations in the upper airway under different oxygen supply flow rates.Results Pressures at typical upper airway locations obtained by computational and physical simulations turned out to be in good agreement;both peak inspirational pressure(PIP)and positive end-expiratory pressure(PEEP)increased quadratically with the increase of oxygen supply flow rate;and the air pressure distribution was more uniform in the laryngeal cross-section as compared to the nasal part of the upper airway.Conclusions This study may provide a theoretical support for optimization of the setting of oxygen suppy flow rate and the selection of PEEP effect assessment position in the clinical application of HFNC oxygen therapy.
