OBJECTIVE: To investigate the current status of clinical genetics specialization development and the diagnostic and therapeutic capabilities for hereditary diseases across medical institutions in Shanghai, and to assess the necessity and feasibility of establishing training bases for clinical genetics specialists. METHODS: By employing a cross-sectional survey design, the Clinical Genetics Committee of Shanghai Medical Association has conducted questionnaire surveys from March to April 2025 across 54 healthcare institutions in Shanghai (including 33 tertiary hospitals and 21 secondary hospitals). The survey involved administrative departments and medical personnel from 15 clinical specialties. The survey has covered current genetic disease diagnosis and treatment practices, relevant and specialised disease types, genetic department establishment, testing capabilities, personnel teams, and training requirements. RESULTS: The results revealed that 78.0% of clinical departments surveyed had treated patients with hereditary disorders. Shanghai possesses diagnostic and therapeutic expertise for over 95% of hereditary diseases listed in its rare disease catalogue, reflecting both the practical clinical demand for such conditions and the city's overall diagnostic and therapeutic strengths in this field. Nevertheless, significant disparities exist in the development of genetics departments across different tiers of healthcare institutions. Resources for genetic testing capabilities (including molecular, cellular, and biochemical testing) are also unevenly distributed across different tiers of hospitals. The survey further revealed that only 26.0% of departments believe that their current physician structure fully meets the diagnostic and treatment demands. Over 90% of departments consider standard training for clinical genetic specialists necessary, with 74.0% expressing willingness to participate in establishing training bases. Based on above findings and thorough deliberation, the Clinical Genetics Committee of the Shanghai Medical Association proposes advancing specialist training and discipline development through establishing a standard training system. The committee has drafted a three-year training protocol featuring a "joint training"-centered model, recommending a pilot-first, dynamically optimized strategy for steadily advancing training base development. CONCLUSION Shanghai faces substantial demand for genetic disease diagnosis and treatment, yet exhibits shortcomings in clinical genetics specialization development, resource allocation, and talent pipeline cultivation. To establish a standard training system holds significant practical importance and is underpinned by a broad demand.

Under the background of the Healthy China strategy， the integration of traditional Chinese medicine （TCM） into the public health emergency response system has become an important measure to enhance the capacity for coping with public health emergencies. In recent years， the role of TCM in responding to such emergencies has become increasingly prominent. Taking major emerging epidemics as an example， TCM has developed a rich theoretical system and practical experience in epidemic prevention and treatment over thousands of years， and has played a significant role in successive outbreaks with its unique advantages. Based on the concept of ''preventing disease before its onset'' and the theoretical framework of treatment based on syndrome differentiation， TCM has achieved remarkable results through early intervention and full participation in the integrated model of TCM and Western medicine， from severe acute respiratory syndrome （SARS） to corona virus disease-2019 （COVID-19）， in improving clinical symptoms and outcomes， reducing adverse reactions， and promoting recovery. From the perspective of the Healthy China strategy， this paper systematically reviews the historical development of TCM in epidemic prevention and treatment， with particular attention to recent epidemics such as SARS， influenza A （H1N1）， and COVID-19. It further examines the similarities and differences between TCM and Western medicine in responding to major emerging epidemics， as well as relevant policies related to TCM in epidemic prevention and control. In addition， it summarizes the existing problems in TCM's role in the prevention and treatment of major emerging epidemics， and explores measures to improve its rapid response capacity under the Healthy China strategy. This study not only provides a ''Chinese solution'' for the prevention and control of newly emerging infectious diseases worldwide， but also offers theoretical and practical references for strengthening the public health emergency response system， carrying strategic significance for promoting the modernization and internationalization of TCM.

Microglia, the resident immune cells in the central nervous system (CNS), rapidly transition from a resting to an active state in the acute phase of ischemic brain injury. This active state mediates a pro-inflammatory response that can exacerbate the injury. Targeting the pro-inflammatory response of microglia in the semi-dark band during this acute phase may effectively reduce brain injury. Shionone (SH), an active ingredient extracted from the dried roots and rhizomes of the genus Aster (Asteraceae), has been reported to regulate the inflammatory response of macrophages in sepsis-induced acute lung injury. However, its function in post-stroke neuroinflammation, particularly microglia-mediated neuroinflammation, remains uninvestigated. This study found that SH significantly inhibited lipopolysaccharide (LPS)-induced elevation of inflammatory cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and inducible nitric oxide synthase (iNOS), in microglia in vitro. Furthermore, the results demonstrated that SH alleviated infarct volume and improved behavioral performance in middle cerebral artery occlusion (MCAO) mice, which may be attributed to the inhibition of the microglial inflammatory response induced by SH treatment. Mechanistically, SH potently inhibited the phosphorylation of serine-threonine protein kinase B (AKT), mammalian target of rapamycin (mTOR), and signal transducer and activator of transcription 3 (STAT3). These findings suggest that SH may be a potential therapeutic agent for relieving ischemic stroke (IS) by alleviating microglia-associated neuroinflammation.

Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Objective To build an inpatient hospital discharge preparation service management platform,to explore its application outcomes,and to enhance the quality of discharge preparation service management.Methods A research team was set up,and the literature was referenced.The platform was built on the basis of connecting and optimizing various existing information systems in the hospital,including 6 modules:evaluation,implementation of nursing,referral,monitoring feedback,follow-up,and continued nursing.Patients admitted to a tertiary comprehensive hospital were conveniently selected as research subjects in Shandong Province from August 2023 to January 2024.The 97 patients included after the platform application(November 2023 to January 2024)were selected as an experimental group,and the 97 patients included before the platform application(August to October 2023)were selected as a control group.The rate of unplanned readmission within 30 days,the utilization rate of"Internet+Nursing Services",and the time for assessing the demand for discharge planning service were compared between the 2 groups.In addition,in February 2024,300 healthcare professionals from the same hospital were selected to evaluate their satisfaction with the use of the platform.Results There were 7 cases dropping out in each of the 2 groups.The rate of unplanned readmission within 30 days in the experimental group was lower than that in the control group;the utilization rate of"Internet+Nursing Services"was higher than that in the control group;the time for assessing the demand for discharge planning service was less than that in the control group,with statistically significant differences(P＜0.05).In the satisfaction survey of medical staff on the use of the platform,the effective questionnaire response rate was 94.67％,and the score of the clinical nursing information system effectiveness evaluation scale was(100.84±16.48)points.Conclusion The use of this platform can reduce the unplanned readmission rate of patients within 30 days,promote the development of"Internet+Nursing Services",reduce the time for assessing the needs of discharge planning services,and medical staff are highly satisfied with the use of the platform.

BACKGROUND:Porous structures based on triple periodic minimal surfaces are one of the most promising orthopedic biostructures,among which the Gyroid structure is characterized by high specific surface area,high permeability,and zero mean curvature.OBJECTIVE:To screen the wall thickness interval of TC4 bionic bone scaffolds with 4 mm single-cell Gyroid structure matching the elastic modulus range of cancellous bone of the mandible through finite element analysis combined with mechanical compression test testing.METHODS:The finite element model of the 4 mm single-cell Gyroid structure with different wall thickths(0.1,0.2,0.3,0.4,0.5,0.6,0.7,and 0.8 mm)was established.The equivalent elastic modulus of the Gyroid structure was analyzed,and the wall thickness interval of the Gyroid structure matching the elastic modulus range of the maxillary resinous bone was selected with different wall thicknesses of 0.2,0.3,0.4,0.5,0.6,and 0.7 mm,respectively.According to finite element analysis screening results,the material selected was Ti6Al4V.Selective laser melting was used to prepare 3D printed Gyroid structure specimens.The surface treatment was carried out by large-grained sand blasting and acid etching.The elastic modulus and compressive strength of the specimen were tested by mechanical compression experiment.RESULTS AND CONCLUSION:(1)The finite element analysis results showed that the equivalent elastic modulus of the Gyroid structure increased with the increase of wall thickness,and the equivalent elastic modulus of the Gyroid structure with wall thickness of 0.2-0.7 mm was within the range of the elastic modulus of the spongy bone of the mandible(1.5-4.0 GPa),which was used for 3D printing of the Gyroid structure specimen.(2)The mechanical compression test results showed that the elastic modulus and compressive strength of the Gyroid structural specimen increased with the increase of wall thickness,and the elastic modulus of the Gyroid structural specimen with wall thickness of 0.3-0.5 mm was within the range of the elastic modulus of the cancellous bone of the mandible.The compressive strength of the Gyroid specimen with 0.3-0.7 mm wall thickness was consistent with the mechanical properties of the mandible.(3)The results show that the Gyroid structure of 0.3-0.5 mm wall thickness is compatible with the range of elastic modulus of the mandible.

BACKGROUND:Condylar prosthesis replacement,as one of the surgical methods for the treatment of temporomandibular joint diseases,not only needs to restore the morphology and function,but also needs to ensure long-term stable application.OBJECTIVE:To design finite element analysis of a customized Gyroid condylar prosthesis.METHODS:Gyroid structure specimens with different wall thicknesses(250,350,450,550,650,and 750 μm)were designed by software.Finite element simulation compression experiments were carried out to test the elastic modulus of the specimens.The Gyroid structure wall thickness range that matches the elastic modulus of mandibular cancellous bone and whose pore size meets the osteogenesis conditions was screened out.This range was subdivided and Gyroid structure specimens were made using 3D printing technology.Mechanical compression experiments were carried out on a universal testing machine.The Gyroid structure wall thickness that meets the mechanical properties of mandibular bone,has an easier osteogenesis and a smaller strength was screened out by elastic modulus and compressive strength,and subsequent experiments were carried out.A three-dimensional model of a customized Gyroid condylar prosthesis was designed,and the finite element analysis of the blade jaw position and cusp interdigitation position of the model under natural occlusion was simulated.RESULTS AND CONCLUSION:(1)Finite element analysis results showed that with the increase of wall thickness,the elastic modulus of Gyroid structure specimens increased.The elastic modulus of Gyroid structure specimens with wall thickness of 350,450,550,650,and 750 μm matched the elastic modulus of mandibular cancellous bone.Since the subsequent experiments needed to be subdivided into groups and the pore size of the 550,650,and 750 μm wall thickness group(pore size 800-1 000 μm)was within the osteogenesis range.Gyroid structure specimens with wall thickness of 550,600,650,700,and 750μm were selected for mechanical compression experiments on a universal testing machine.(2)The results of mechanical compression experiments showed that with the increase of wall thickness,the elastic modulus and compressive strength of Gyroid structure specimens increased.The elastic modulus of Gyroid structure specimens with wall thickness of 550,600,and 650 μm was within the elastic modulus of the mandibular cancellous bone.Finally,the wall thickness of 650 μm and the pore size of 900 μm were selected to construct the three-dimensional model of the mandibular customized Gyroid condylar prosthesis.(3)The results of finite element analysis of three-dimensional model of the mandibular customized Gyroid condylar prosthesis showed that the stress of the articular disc in the edge-to-edge occlusion was mainly concentrated on the lower surface of the anterior middle band,and the stress of the articular disc in the interposition of tooth tips was mainly concentrated on the lateral surface of the lower surface.The maximum displacement and the maximum equivalent stress of the left and right articular discs in the edge-to-edge occlusion and the interposition of tooth tips were similar.The maximum displacement was 0.031,0.030,0.028,and 0.018 mm,and the maximum equivalent stress was 2.87,2.30,2.73,and 1.71 MPa,respectively.(4)The results showed that the Gyroid structure with a wall thickness of 650 μm was consistent with the mechanical properties of the mandible,which reduced the strength of the titanium alloy and reduced the damage of the articular disc caused by the customized Gyroid condylar prosthesis.
