Objective: To analyze the epidemiological characteristics of pulmonary tuberculosis (PTB) among college students in Yangzhou from 2020 to 2024, so as to provide a scientific basis for developing prevention and control strategies. Methods: An epidemiological investigation was conducted among 162 college students with PTB, and 7 134 of their contacts were screened. Data were obtained from the tuberculosis information management system and on campus screening records. Using descriptive epidemiological methods, trends in incidence, seasonal distribution, and bacteriological characteristics were analyzed. Results: From 2020 to 2024, the annual average incidence of pulmonary tuberculosis among college students in Yangzhou was 29.42 per 100 000, showing an overall fluctuating downward trend ( χ 2=12.36, P <0.01). Cases were mainly concentrated in summer and autumn, with the highest proportion in autumn (41.36%, 67/162), followed by summer (23.46%, 38/162). The proportion of etiologically positive cases increased from 37.21% in 2020 to 71.43% in 2024; among positive cases, the proportion of latent tuberculosis infection (LTBI) decreased from 66.67% (10/15) to 26.67% (4/15). The etiological positive rate was higher in females than in males ( χ 2= 11.76 , P <0.01). Comparison of screening methods showed that among index cases, the LTBI detection rate of the recombinant Mycobacterium tuberculosis fusion protein skin test (C-TST) was higher than that of the tuberculin skin test (TST), but the difference was not statistically significant ( χ 2=0.65, P =0.42); among close contacts, the detection rate of TST was higher than that of C-TST (15.1%,10.1%; χ 2=5.23, P <0.05). Conclusion From 2020 to 2024, the annual average incidence of pulmonary tuberculosis among college students in Yangzhou showed an overall fluctuating downward trend, with differences in TB infection screening methods and gender.

Aim To explore the effect of age on myocardial remodeling after percutaneous coronary intervention(PCI)in patients with acute anterior myocardial infarction.Methods This study was a cross-sectional study analyzing clinical data of regular follow-up at 1,3,6 and 12 months after PCI for acute anterior myocardial infarction.According to the age of the patients,they were divided into a low age group(＜65 years old)and a high age group(≥65 years old).The differences in baseline data,biochemical indexes,coronary angiography,inflammatory factor levels,and cardiac ultrasound indexes between the two groups were analyzed,and the correlation analysis between age and inflammatory factors and the multivariate linear regression analysis of diastolic function were performed.Results A to-tal of 87 patients with acute anterior myocardial infarction were selected,aged(62±13)years,including 67 males(77.0％),43 in the low age group and 44 in the high age group.Compared with the low age group,the levels of inflam-matory factors such as C-reactive protein,interleukin-1β(IL-1β),interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)increased in the high age group,while ultrasound indicators such as mitral valve annulus septal e',mitral valve flow velocity E/A,and mitral valve annulus sidewall e'decreased(P＜0.05).Older age was an independent risk factor for a decrease in mitral valve flow velocity E/A,mitral valve annulus sidewall e'and mitral valve annulus septal e'in patients with acute anterior myocardial infarction 6 months after PCI(P＜0.05).Conclusion Age is an independent risk factor for reduced diastolic function after PCI in acute anterior myocardial infarction,inflammatory factor such as IL-1β,IL-6 and TNF-α may play a role in the impaired diastolic function after PCI in age-related acute anterior myocardial infarction.

Objective To systematically evaluate and integrate qualitative studies on perception of exercise behaviors in community-dwelling older adults with frailty,and to provide references for clinical development of targeted exercise intervention strategies.Methods A systematic search of PubMed,Medline,Embase,PsycINFO,the Cochrane Library,SinoMed,Wanfang Database,CNKI,and VIP Database for qualitative studies on perception of exercise behaviors in older adults with frailty in the community was conducted from the inception of the databases to June 2024.Literature quality was evaluated using the Australian Joanna Briggs Institute Centre for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research(2016 edition),and Meta-synthesis was performed using the theme synthesis method.Results A total of 10 papers were included,grouped into 10 categories and integrated into the 3 domains of the capability,opportunity,and motivation-behavior model(COM-B model),i.e.Preparation for exercise behavior is influenced by capability factors(physical reserve,knowledge reserve,psychological preparation);stage-specific motivational evolution promotes the internalization of exercise behavior(guiding,focusing,stimulating,and maintaining);external conditions provide opportunities for exercise behavior(individual interaction,community environment,and social support).Conclusion Perceptions of exercise behavior among community-dwelling older adults with frailty or are complex and influenced by a variety of factors.Future exercise intervention strategies should consider modifiable factors,enhance knowledge education,stimulate intrinsic motivation,and solidify external conditions,while also accommodating individual differences and preferences,so as to promote exercise participation and health enhancement in this group.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective:To investigate the feasibility, safety, and short-term efficacy of the application of near-infrared fluorescence imaging of tharacic duct(NFITD) by indocyanine green(ICG) in minimally invasive McKeown esophagectomy(MIME).Methods:The clinical data of the patients underwent MIME for esophageal cancer in the First Affiliated Hospital of University of Science and Technology of China From January 2024 to April 2024 were restrospectively analyzed. There were divided into a indocyanine green imaging of thoracic duct(ITD) group and a non indocyanine green imaging of thoracic duct(NITD) group according to intraoperative visualization of morphological patterns of the thoracic duct. The clinicopathologic factors, preoperative adjuvant therapy, surgery-related indicators, postoperative complications were compared between the two groups.Results:In the comparison of general data between the two groups of patients, there were differences in preoperative neoadjuvant therapy between the ITD group and the NITD group. However, there were no significant differences between the two groups in terms of age, gender, tumor segmentation, degree of differentiation, smoking history, drinking history, and preoperative comorbidities. In the perioperative data, the ITD group had advantages in total pleural effusion volume on the third day after surgery, total hospitalization cost, and intraoperative discovery of thoracic duct injury( P<0.05). In terms of the number of metastatic lymph nodes, the ITD group was higher than the NITD group( P<0.05). There were no significant differences between the two groups in terms of operation time, postoperative hospital stay, total pleural effusion volume on the 1st and 2nd days after operation, whether the thoracic duct was ligated, whether there was thoracic adhesion, pTNM stage, the number of lymph node dissection stations and the number of lymph node dissections. In terms of the minor complications of chylothorax after surgery, the ITD group was significantly less than the NITD group. There was no significant difference in other complications between the two groups of patients. Conclusion:NFITD combined with MIME can be safety and effectively performed for patients with esophageal cancer with significant advantages in reducing postoperative chylothorax.

Objective:To compare the efficacy of robot system-assisted versus freehand screw revision for ankylosing spondylitis (AS) with lower cervical fractures.Methods:A multicenter retrospective cohort study was conducted to analyze the clinical data of 57 patients with AS combined with lower cervical fractures admitted to Honghui Hospital Affiliated to Xi'an Jiaotong University School of Medicine, Henan Provincial People's Hospital, Zhengzhou Orthopedic Hospital, and Qilu Hospital of Shandong University, including 46 males and 11 females, aged 38-77 years [(65.4±9.5)years]. Injury segments involved C 3 in 7 patients, C 4 in 13, C 5 in 25, C 6 in 10, and C 7 in 2. All the patients underwent revision surgery, among whom, 22 patients were treated with robot system-assisted cervical pedicle screw placement (robot nailing group, with 190 screws), and 35 with freehand cervical pedicle screw placement (freehand nailing group, with 300 screws). The operative duration, intraoperative bleeding volume, frequency of intraoperative fluoroscopy, incision length, and length of hospital stay of the two groups were compared; the time of single nscrew insertion, the number of single nail revisions, the distance between screws and the anterior cortex, the accuracy of screw placement of grade 0 and grade 0+1 were recorded in the two groups. The visual analogue scale (VAS), Japanese Orthopedic Society (JOA) score, neck dysfunction index (NDI), American Spine Injury Association (ASIA) classification before operation, at 3 days, 3 months after operation and at the last follow-up were compared between the two groups. The complication rate was also noted. Results:All the patients were followed up for 12-16 months [(14.3±2.1)months]. The operative duration, intraoperative bleeding volume, and frequency of intraoperative fluoroscopy were (186.4±12.9)minutes, (486.1±68.6)ml, and (3.4±1.3)times in the robot nailing group, which were shorter or less than (206.7±14.4)minutes, (660.3±45.2)ml, and (13.5±3.6)times in the freehand nailing group ( P<0.01). The incision length was (9.4±2.4)cm in the robot nailing group, longer than (5.6±1.2)cm in the freehand nailing group ( P<0.01), and the length of hospital stay was (3.7±0.4)days, shorter than (4.4±1.4)days in the freehand nailing group ( P<0.01). The length of single nail insertion, the number of single nail revision, and the distance between the screws and the front cortex were (6.5±0.4)minutes, (1.1±0.1)times, and (3.5±1.3)mm in the robot nailing group, which were shorter or less than (11.6±0.2)minutes, (1.5±0.2)times, and (12.4±4.7)mm in the freehand nailing group ( P<0.01). The accuracy of the screw placement in the robot nailing group was 90.0% (171/190) and 95.8% (182/190) with level 0 and 0+1 screws, better than 80.0% (240/300) and 89.0% (267/300) in the freehand nailing group ( P<0.05). There was no significant difference in VAS, JOA score, NDI, or ASIA grading between the two groups before operation ( P>0.05). The VAS, JOA, and NDI scores at 3 days after operation were (3.1±0.6)points, (12.1±1.2)points, and (15.6±2.9)points, respectively in the robot nailing group, which were better than (5.0±1.4)points, (11.3±1.1)points and (22.5±3.7)points, respectively in the freehand nailing group ( P<0.05). No statistically significant difference was observed in the ASIA grade between the two groups at 3 days after operation ( P>0.05). There were no significant differences in VAS, JOA, NDI scores, or ASIA grading between the two groups at 3 months after operation and at the last follow-up ( P>0.05). Compared with those before operation, the VAS, JOA, NDI scores, and ASIA grading were significantly improved at 3 days, 3 months after operation and at the last follow-up in the two groups, which were further improved with the passage of time. Two patients in the robot nailing group had pneumonia, with a complication rate of 9% (2/22), while 2 patients in the freehand nailing group had dural sac rupture and cerebrospinal fluid leakage and 3 had lung infection after operation, with a complication rate of 14% (5/35) ( P<0.05). Conclusion:Compared with freehand nailing, the robot system-assisted nailing revision for AS with lower cervical fracture has more advantages in terms of the operative duration, length of hospital stay, intraoperative bleeding volume, frequency of intraoperative fluoroscopy nailing speed and accuracy, screw holding force, early pain relief, function restoration, and complication rate, despite longer surgical incision.
