Objective To introduce the causes of accidents and the diagnosis and treatment of two patients with radiation-induced skin injury admitted to our hospital in 2023, and to provide a reference for the clinical treatment of subsequent radiation-induced skin injury. Methods The clinical treatment process of two patients with acute skin injury caused by external radiation exposure were summarized and analyzed. Results The exposure history of the two patients was reconstructed, the flaw detection scenario was simulated, the biological dose and hand skin exposure dose were estimated, and the infrared thermal imaging device was used for dynamic monitoring. A comprehensive analysis was conducted based on clinical manifestations and other data. The diagnosis of “Xie” was excessive exposure combined with acute radiation-induced skin injury on both hands (Grade IV for the right hand palm, index finger, and middle finger and Grade II for the left hand little finger). The diagnosis of “Hao” was acute radiation-induced skin injury on both hands (Grade I). The two patients received different clinical treatment measures: “Xie” was treated with both local and systemic therapies, while “Hao” was mainly treated with systemic therapy. Conclusion After systematic and effective treatment, the radiation-induced skin injuries healed in both patients.

Interstitial cystitis/bladder pain syndrome (IC/BPS) is a refractory condition characterized by chronic inflammation of the bladder wall, disruption of the urothelial barrier, and neural sensitization. Current therapies, such as oral pentosan polysulfate sodium (PPS) or intravesical hyaluronic acid instillations, offer limited efficacy due to transient effects and an inability to reverse tissue fibrosis. Platelet-rich plasma (PRP), a regenerative medicine approach, has demonstrated significant therapeutic potential in urological disorders through the synergistic actions of its multiple growth factors. This review summarizes the latest advances in PRP therapy for IC/BPS, revealing that the underlying mechanisms primarily involve the release of diverse growth factors, suppression of inflammatory responses, restoration of the urothelial barrier, and modulation of nerve axonal regeneration. Clinically, PRP therapy significantly alleviates symptoms including pelvic/bladder pain, urinary frequency, nocturia episodes, and improves patients'quality of life. Furthermore, it offers advantages such as convenient administration, a favorable safety profile, and strong feasibility, presenting new therapeutic methods and options for the clinical treatment of IC/BPS.

Benign prostatic hyperplasia （BPH） is a common chronic progressive disease in middle-aged and elderly men， characterized by prostate enlargement and bladder outlet obstruction， leading to symptoms such as frequent urination， urgency， and difficulty urinating. The pathogenesis of BPH involves factors such as aging， hormonal metabolic abnormalities， inflammatory responses， and imbalances in cell proliferation and apoptosis. Currently， the main treatment methods for BPH include medication， physical therapy， and surgical intervention. However， medication may cause side effects like sexual dysfunction and hypotension， physical therapy has limited efficacy， and surgery carries risks and postoperative complications. Therefore， there is an urgent need to find safer and more effective treatment options. Traditional Chinese medicine （TCM）， with its focus on treatment based on syndrome differentiation and a holistic approach， offers therapeutic advantages through multiple pathways and mechanisms. Recent studies have shown that TCM regulates pathways such as phosphoinositide-3-kinase/protein kinase B （PI3K/Akt）， nuclear factor-κB （NF-κB）， mitogen-activated protein kinases （MAPK）， nuclear factor E₂-related factor 2/antioxidant response element （Nrf2/ARE）， androgen receptor （AR）， transforming growth factor-β （TGF-β）/Smad， and hypoxia-inducible factor-1α/vascular endothelial growth factor （HIF-1α/VEGF） to inhibit oxidative stress and inflammatory response， reduce prostate cell proliferation， and promote apoptosis， thus exerting therapeutic effects. This article summarizes and analyzes the roles of these signaling pathways in the occurrence and development of BPH and the mechanisms of TCM intervention， aiming to provide scientific evidence for clinical treatment and drug development for BPH.

Thoracolumbar trauma, including fractures, dislocations and spinal cord injuries, often result from high-energy injuries such as traffic accidents and falls from heights. It not only causes severe pain and restricted movement for patients, but also leads to neurological damage and even permanent disability. Currently, the diagnosis and treatment of thoracolumbar trauma are faced with many problems, such as possible missed diagnosis and misdiagnosis, lack of individualized and standardized treatment plans, and lack of objective and quantitative metrics for postoperative assessment. Artificial intelligence (AI) technology offers innovative ideas to these problems. Among them, the core AI technology such as machine learning (ML), deep learning (DL), computer vision, and robotics has demonstrated outstanding capabilities in medical image analysis, clinical decision support, etc., which can significantly improve the diagnostic precision, surgical planning efficiency, and postoperative management level of thoracolumbar trauma. At present, application of AI technology in cross-modal data integration, clinical decision support, and long-term efficacy prediction in the field of thoracolumbar trauma remains to be systematically sorted out. To this end, the authors reviewed the research progress of AI technology in the diagnosis, treatment, and postoperative management of thoracolumbar trauma, providing a reference for a wide application of AI technology in the management of thoracolumbar trauma.

Objective: To study the effects and potential mechanisms of the aquaporin 1(AQP1) inhibitor acetazolamide(AZ) on the proliferation, apoptosis, and inflammatory response of rheumatoid arthritis(RA) fibroblast-like synoviocytes(FLS). Methods: TNF-α-induced RA-FLS was served as in vitro RA model. MTT assay, IF staining, and EdU incorporation assay were applied to study AZ′s effects on RA-FLS proliferation. Hoechst staining, flow cytometry analysis of Annexin V-FITC/PI-stained cells, and mitochondrial membrane potential detection experiments were used to detect cell apoptosis. ELISA and quantitative real-time PCR methods were used to measure pro-inflammatory cytokine production. Cell autophagy was evaluated using IF staining and mCherry-GFP-LC3B puncta assay. Western blot was performed to detect the levels of autophagy, apoptosis, and proliferation-related proteins. Moreover, the role of autophagy inhibition in AZ′s effects on RA-FLS was examined by co-treating with the autophagy activator rapamycin(RAPA) or the autophagy inhibitor 3-methyladenine(3-MA). Results: AZ dose⁃dependently inhibited cell proliferation , promoted apoptosis , and reduced the production of pro⁃inflammatory cytokines in RA⁃FLS. Furthermore , AZ suppressed cytoprotective autophagy in these cells , as evidenced by decreased LC3B levels ( P < 0. 05 ) , increased p62 expression ( P < 0. 05 ) , and reduced autophagic flux ( P <0. 01) . Particularly , AZ ′s beneficial effects were reversed by RAPA⁃induced autophagy activation and enhanced by 3 ⁃MA⁃induced autophagy inhibition. Conclusion This study provides the first evidence that AZ hinders cytoprotective autophagy , thereby alleviating the hyperproliferation , apoptosis resistance , and aberrant inflammatory response of RA⁃FLS , revealing the core role of autophagy inhibition in AZ ′s anti⁃RA effects.

Particle size and surface properties are crucial for lymphatic drainage (LN), dendritic cell (DC) uptake, DC maturation, and antigen cross-presentation induced by nanovaccine injection, which lead to an effective cell-mediated immune response. However, the manner in which the particle size and surface properties of vaccine carriers such as mesoporous silica nanoparticles (MSNs) affect this immune response is unknown. We prepared 50, 100, and 200 nm of MSNs that adsorbed ovalbumin antigen (OVA) while modifying β-glucan to enhance immunogenicity. The results revealed that these MSNs with different particle sizes were just as efficient in vitro, and MSNs with β-glucan modification demonstrated higher efficacy. However, the in vivo results indicated that MSNs with smaller particle sizes have stronger lymphatic targeting efficiency and a greater ability to promote the maturation of DCs. The results also indicate that β-glucan-modified MSN, with a particle size of ∼100 nm, has a great potential as a vaccine delivery vehicle and immune adjuvant and offers a novel approach for the delivery of multiple therapeutic agents that target other lymph-mediated diseases.

Nuclear emergency medical rescue is one of the important courses of military medical professional education, and improving the training level of nuclear emergency medical rescue plays a very important role in improving post competency of trainees. Based on the problem of disconnection between "teaching" and "need" in the occupational education of nuclear emergency medical rescue in the past, this study proposes the curriculum goal of "the combination of three abilities" and performs the optimization and practice of the occupational education curriculum system of nuclear emergency medical rescue from the aspects of curriculum setting, curriculum content, teaching methods, and assessment and evaluation. The results show that the new curriculum system can significantly improve the comprehensive ability of nuclear emergency medical rescue among trainees and better meet the requirements for their posts, thereby playing an important role in cultivating high-quality military medical talents in nuclear emergency medical rescue.
