Duchenne muscular dystrophy (DMD) is an X-linked recessive genetic disorder caused by mutations in the dystrophin gene, classified as a rare congenital muscular disease. Its clinical features include progressive skeletal muscle weakness, often involving respiratory and cardiac muscles, and frequently associated with spinal deformities. This paper reports the diagnosis, perioperative management, and follow-up of a case of DMD with multisystem involvement and severe scoliosis, aiming to provide a reference for clinicians in the diagnosis and treatment of such diseases.

Objective:To construct a "local-systemic" dual-track prediction model integrating the resistance index (RI) score of bilateral sacroiliac joints and the systemic immune-inflammation index (SII), and to evaluate its predictive efficacy for the active stage of ankylosing spondylitis (AS).Methods:A total of 205 patients with ankylosing spondylitis (AS) from the Second Hospital of Lanzhou University between April 2022 and April 2025 were retrospectively enrolled and categorized into an active group ( n=113) and a remission group ( n=92). Hematological parameters and ultrasound data were collected. The resistance index (RI) of the synovial area in bilateral sacroiliac joints was measured by Doppler ultrasound and scored as follows: RI < 0.5: 3 points; RI 0.5~0.55: 2 points; RI > 0.55: 1 point; undetectable blood flow: 0 points. A total bilateral RI score (range 0 to 6) was calculated. The systemic immune-inflammation index (SII) was derived as (neutrophils× platelets)/lymphocytes. Normality was tested for all continuous variables; normally distributed data were compared using the t-test, while non-normally distributed data were analyzed with the Mann-Whitney U test. Categorical variables were compared using the χ2 test or analysis of variance.Variable selection was performed using Lasso regression, and a multivariate logistic regression model was developed to assess predictive performance. Results:The proportion of patients with a bilateral RI total score≥5 was significantly higher in the active group compared to the remission group (50 of 113, 44.3% vs 2 of 92, 2.2%, χ2=55.63, P<0.001). Multivariate logistic regression analysis, after adjustment for confounding variables, identified the SII [ OR(95% CI)=1.01(1.00, 1.01), P<0.001], bilateral RI total score [ OR(95% CI)=1.67(1.29, 2.26), P<0.001], erythrocyte sedimentation rate [ OR(95% CI)=1.19(1.11, 1.30), P<0.001], and mean corpuscular hemoglobin concentration [ OR(95% CI)=1.09(1.03, 1.17), P<0.001] as independent risk factors for active AS. Conversely, lymphocyte count [ OR(95% CI)=0.42(0.18, 0.92), P=0.030] and globulin [ OR(95% CI)=0.89(0.80, 0.99), P=0.040] were significantly associated with protective effects. The bilateral RI total score demonstrated the strongest predictive effect, with each 1-point increase associated with a 67% elevation in the risk of active disease. ROC curve analysis indicated that the area under the curve (AUC) for predicting whether AS is in the active disease phase was 0.94 for the combined model (SII+bilateral RI total score), compared with 0.93 for the SII-alone model and 0.92 for the bilateral RI total score-alone model, demonstrating superior predictive performance of the combined model (SII+bilateral RI total score). An online prediction tool has been developed based on the combined model. Conclusion:The dual-track prediction model, which integrates local joint hemodynamic characteristics and systemic immune-inflammatory status, facilitates a multidimensional assessment of the risk of active AS and provides an objective basis for early identification.

The disease-syndrome combination animal model in traditional Chinese medicine （TCM） andrology serves as an important bridge linking TCM theory with modern medical research， providing a key experimental platform for elucidating the 'syndrome-disease' correlation mechanism in male-specific diseases and for screening effective prescriptions. This article reviews recent progress in animal model research on common TCM andrological diseases， including prostatic diseases， sexual dysfunction， and male infertility， with a focus on analyzing the application， advantages， and disadvantages of various modeling strategies， such as immune induction， hormonal intervention， and multi-factor combination across different syndrome types. However， despite breakthroughs in model construction techniques， current research still faces several challenges， including insufficient standardization of syndrome differentiation and difficulties in quantifying TCM-specific indicators. Future studies need to optimize model evaluation systems by integrating modern technologies， in order to promote the standardization and internationalization of TCM andrology research.

Methods: Fifty patients who underwent UBE-TLIF and 50 patients who underwent W-TLIF, each with >2 years of follow-up, were retrospectively analyzed. Outcomes included operative parameters, time to postoperative mobilization, paravertebral muscle atrophy and fat infiltration rates, clinical scores (Visual Analog Scale [VAS], Oswestry Disability Index [ODI], Japanese Orthopaedic Association [JOA]), modified Macnab criteria, fusion rates, and complications. Results: Compared with W-TLIF, the UBE-TLIF group had significantly less intraoperative blood loss, shorter operative times, and lower postoperative drainage volumes (p <0.05). The UBE-TLIF group showed faster postoperative recovery and shorter hospital stays. At 6 months, 1 year, and 2 years, W-TLIF patients had higher multifidus and erector spinae atrophy, and greater paravertebral muscle fat infiltration (p <0.05). The UBE-TLIF group also had lower VAS and ODI scores at 1 year and 2 years (p <0.05) and fewer surgical complications (6% vs. 10%). Fusion rates (94% vs. 92%) and modified Macnab outcomes (88% vs. 86%) were comparable (p >0.05). Conclusions UBE-TLIF is associated with reduced intraoperative trauma, quicker recovery, and fewer complications. In the long-term, it better preserves paravertebral muscle integrity and provides superior pain and functional outcomes.

With the development of science and technology, electronic devices have become an inevitable part of our daily life and work. There has been an increase of interest in the use of various video display terminals(VDT). The ocular surface is the first barrier of the visual system to resist the damage of the external environment. In recent years, the number of patients with dry eye has consistently increased with the excessive use of VDT. Blue light produced by VDT, with wavelengths ranging from 400 to 500 nm, has a high energy in visible light. Therefore, blue light may also be an important risk factor for dry eye. In particular, the outbreak of COVID-19 has left people worldwide suffering from increased blue light, which promotes further research into dry eye caused by blue light emitted from VDT. In this review, we summarize the recent studies on the role of blue light produced by VDT in dry eye to provide reference for future related research.

Objective To explore the correlation between the pulmonary artery diameter(PAD),PAD/aortic diameter(AOD),right ventricular diameter(RVD),RVD/left ventricular diameter(LVD)measured on pulmonary artery CT angiography(CTPA)cross-sectional images and the degree of embolism,cardiac biomarkers in patients with medium-to-high risk acute pulmonary embolism(APE).Methods The clinical data of 53 patients with medium-to-high risk APE,who received interventional treatment at the Putian Municipal First Hospital of China From January 2021 to December 2023,were retrospectively analyzed.The PAD,PAD/AOD,RVD,and RVD/LVD were measured on CTPA cross-sectional images.The correlations of the above indexes with CT embolism index(CTEI),N terminal pro B type natriuretic peptide(NT-proBNP),and cardiac troponin Ⅰ(cTnⅠ)were analyzed.Results A weak-moderate positive correlation existed between PAD,RVD,RVD/LVD and CTEI(r=0.506,r=0.310,r=0.452 respectively,P＜0.001,P=0.024,P=0.001 respectively),while no correlation existed between PAD/AOD and CTEI(r=0.247,P=0.075).Compared with the NT-proBNP negative group,in the NT-proBNP positive group the values of PAD,PAD/AOD and RVD/LVD were higher(all P＜0.05),and there was no statistically significant difference in RVD value between the two groups(P＞0.05).A weak-moderate positive correlation existed between NT-proBNP and PAD,PAD/AOD,RVD,RVD/LVD(r=0.454,r=0.326,r=0.302,r=0.405 respectively,P=0.001,P=0.017,P=0.028,P=0.003 respectively).There were no statistically significant differences in PAD,PAD/AOD,RVD and RVD/LVD values between the cTnⅠ negative group and the cTnI positive group(all P＞0.05).No correlation existed between cTnⅠ and PAD,PAD/AOD,RVD,RVD/LVD(r=0.188,r=0.042,r=-0.021,r=0.139 respectively,and P=0.195,P=0.772,P=0.884,P=0.342 respectively).Conclusion CTPA cross-sectional quantitative indicators are helpful in evaluating the embolism degree of APE and right heart function,but it cannot be used to assess myocardial injury.

Objective To study the distribution characteristics of TCM constitutions in the middle-aged and elderly Mongolian population undergoing physical examinations in Inner Mongolia;To analyze the correlation with related risk factors.Methods Health information and related risk factors(including BMI index,lifestyle habits,dietary habits and exercise status)of middle-aged and elderly Mongolian people who visited the physical examination departments of Inner Mongolia Autonomous Region Traditional Chinese Medicine Hospital and Tongliao City Traditional Chinese Medicine Hospital from March 2024 to April 2024 were collected.A total of 213 Mongolian people were surveyed,including 65 people who have lived in Hohhot for more than 2 years and 148 people who have lived in Tongliao for more than 2 years.Through investigation,research and analysis,the distribution characteristics of TCM constitutions in the population and its correlation with related risk factors were observed.Results Constitution distribution:101 people(47.41%)had a moderate constitution.Among the biased constitutions,the phlegm dampness constitution had the highest number of people(64 people,30.05%),with the blood deficiency constitution having the lowest number of people(2 people,0.94%).In the investigation of related risk factors,there was a significant correlation(P<0.01)between phlegm dampness and dietary habits and reduced exercise volume.Moreover,individuals with this constitution tend to have good sleep,reduced physical activity,faster eating and a diet primarily consisting of high-calorie foods(P<0.05).Conclusion The TCM constitution of the Mongolian population in Inner Mongolia is mostly composed of moderate constitution,while the biased constitution is mostly composed of phlegm dampness constitution,which is mainly related to dietary habits and reduced exercise volume.

Malignant pleural mesothelioma(MPM)is strongly associated with a history of asbestos exposure and is characterized by high malignancy,high mortality,and poor prognosis.Current treatments for MPM are limited and generally suboptimal,resulting in a median overall survival(OS)of approximately one year for MPM patients.However,advancements in treatment options,including surgery,radiotherapy,chemotherapy,immunotherapy and targeted therapy,have brought new hope to patients with MPM.For early-stage MPM patients categorized under the TNM staging system,surgical treatment is feasible and can improve survival rates and quality of life.However,there is still debate regarding the optimal surgical approach for MPM.In addition to surgery,radiotherapy plays a vital role in MPM treatment.It is often used as prophylactic treatment or for alleviating local symptoms in advanced stages.Radiotherapy can also serve as neoadjuvant or adjuvant therapy in surgical contexts.For patients experiencing local progression or isolated distant metastases after systemic treatment,radiotherapy is a viable option.The advent of advanced radiotherapy techniques,such as intensity-modulated radiotherapy(IMRT)and volumetric intensity-modulated arc therapy(VMAT),has significantly improved the precision and efficacy of radiotherapy while minimizing damage to healthy tissues.Furthermore,brachytherapy can relieve pain or act as a localized supplemental therapy.Chemotherapy remains the standard treatment for MPM.The combination of pemetrexed and platinum-based drugs is widely applied as first-line therapy and has been shown to significantly extend survival.However,commonly used second-line regimens often yield suboptimal results.In recent years,immunotherapy has developed rapidly.Dual immunotherapy with nivolumab and ipilimumab has demonstrated impressive clinical efficacy and safety.The combination of immunotherapy and chemotherapy has also notably extended patients'median survival.Multiple clinical trials have confirmed that this combination therapy benefits patients.Currently available targeted therapies for MPM primarily focus on anti-angiogenesis.Bevacizumab combined with chemotherapy has established its position as a first-line treatment.Research on ramucirumab and apatinib suggests that these drugs have certain efficacy and safety profiles.Beyond conventional treatment options,the UV1 cancer vaccine combined with dual immunotherapy offers new hope for patients.Chimeric antigen receptor T(CAR-T)cell therapy is an emerging treatment method being investigated in MPM patients,with phase Ⅰ clinical trials demonstrating good antitumor effects.Additionally,some antibody-drug conjugates are becoming therapeutic options for MPM through precise targeting.Tumor treating fields combined with chemotherapy has also shown efficacy in extending survival.Despite the increasing variety of treatment options for MPM,its diagnosis and treatment still face numerous challenges,including difficulties in early detection,treatment resistance,and a lack of large-scale evidence-based clinical studies.Future research should focus on improving early diagnosis rates,developing new treatment strategies,overcoming resistance,and advancing personalized therapy.Strengthening the integration of basic research and clinical trials will also be essential.Through multidisciplinary collaboration and continuous innovation,it is hoped that more effective and safer treatment options will become available,ultimately improving the prognosis of MPM patients.

Sarcopenia, characterized by the loss of muscle mass and function, significantly impacts the quality of life in older adults and has emerged as a major global public health challenge.With the aging population, the incidence of sarcopenia continues to rise, necessitating urgent in-depth studies on effective treatments and its pathogenesis.Exosomes serve as effective carriers for intercellular substance transfer, participating in the physiological regulation and pathological changes of organic cells by transporting specific nucleic acids, proteins, and lipids.Although the potential role of exosomes in sarcopenia has been identified, the specific mechanisms remain poorly understood, and clinical applications are still in the early stages of exploration.This review outlines the role of exosomes from various sources in the communication of skeletal muscle satellite cells and their impact on the occurrence and development of sarcopenia.It also explores their potential applications as biomarkers and therapeutic strategies, providing new ideas and directions for the prevention and treatment of sarcopenia.As research progresses, exosomes are expected to lead to novel treatment options for patients with sarcopenia, ultimately improving their quality of life and health.
