Hyperthyroidism （HT） is frequently complicated by atrial fibrillation （AF） in clinical practice. Based on traditional Chinese medicine （TCM） zang-xiang （藏象） theory and clinical experience， both HT and AF are closely associated with dysfunction of the liver. The pathogenesis is initiated by the liver failing to govern the free flow of qi， and liver constraint and qi stagnation， with the key turning points being liver constraint transforming into fire and the internal stirring of liver wind， ultimately leading to liver blood depletion and insufficient nourishment of the heart spirit. Thus， it is proposed to treat the disease from the liver， with stage-specific therapeutic approaches according to the evolution of the disease. In the early stage， the treatment should focus on soothing the liver and relieving constraint to reduce goiter and calm the heart， while in the progressive stage， the method of clearing liver and draining fire is suggested to subdue yang and stabilize palpitations. In the acute stage， the strategy is calming the liver and nourishing yin to subdue yang and extinguish wind. In the later stage， it is suggested to soften the liver and benefit qi， so as to nourish yin and restore pulse. These methods are sequentially applied to synergistically reduce goiter and stabilize palpitations， providing a therapeutic approach for HT complicated by AF.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. Septic shock is the primary cause of mortality in sepsis, with its core pathophysiological mechanism being severe ischemia and hypoxia in critical units—composed of microcirculation and the mitochondria of functional cells—resulting from disruptions in blood flow and oxygen flow following a dysregulated host response. Due to the systemically convergent yet clinically heterogeneous nature of the host response, current understanding and management strategies for hemodynamics remain inconsistent, often leading to inadequate resuscitation or overtreatment. To improve the quality of care, based on a systematic review of the "blood flow-oxygen flow" theory, an expert panel emphasizes reevaluating septic shock from an integrated perspective of blood flow and oxygen flow, and has formulated the Expert Consensus on Blood Flow and Oxygen Delivery Phenotyping and Clinical Management of Septic Shock (2025). The consensus proposes that clinical typing of blood flow-oxygen flow should comprehensively consider cardiac function, vascular tone, oxygen flow utilization status in critical units, and disease trajectory, while optimizing subtype identification by integrating host response phenotypes and artificial intelligence technologies. It advocates establishing a continuous assessment system through multi-site oxygen flow monitoring for organ perfusion, peripheral perfusion monitoring, and critical care ultrasound. Under the framework of the "critical care triangle", the consensus promotes the implementation of individualized, bundled management strategies, providing guidance for multiple management points to restore blood flow-oxygen flow matching, reduce the risk of organ failure, and decrease patient mortality.

ObjectiveTo systematically evaluate the application of narrative education in undergraduate nursing teaching， to understand the current application status of narrative education， and to provide a theoretical basis for the subsequent establishment of a sound narrative education system. MethodsA systematic search was conducted for studies published in Chinese and English databases on applying narrative education to undergraduate nursing teaching， with the search period ranging from database inception to February 23， 2025. Literature was screened， and relevant information was extracted. A rigorous quality evaluation was conducted on the included studies， and a descriptive analysis was performed on their content. ResultsA total of 20 papers were included， involving 3，180 research subjects， all of whom were undergraduate nursing students. The results of descriptive analysis showed that the teaching model of narrative education primarily encompassed reading narrative works， watching films and videos， performing narrative scenarios， and writing reflective journals. The course setting and content covered pre-teaching preparation and in-teaching implementation. The evaluation of teaching effectiveness included the evaluation of teachers’ teaching methods （student evaluation/self-evaluation） and the evaluation of students’ learning effectiveness （course grade evaluation/humanistic care scale/empathy scale assessment， and others）. ConclusionNarrative education combines abstract concepts with concrete clinical situations， which not only enriches students’ learning experiences but also enhances their humanistic literacy. Meanwhile， it provides teachers with opportunities to develop their narrative teaching skills， which requires them to possess profound professional knowledge and employ narrative techniques to guide students in reflection and critical thinking， thereby improving teaching quality and learning outcomes. Future efforts should consistently deepen the connotation research of narrative education and build a systematic nursing education system.

The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

″Boundarics in biomedicine″(or″Biomedical boundarics″)is an emerging frontier interdisciplinary subject that focuses on addressing key scientific issues related to the formation,identification,and evolution of biological boundaries within living organisms.In this field,the study of tumor boundaries is of particular importance.Imaging tumor boundaries not only helps to reveal the molecular mechanisms of tumor boundary evolution and interaction with the microenvironment,tumor invasion and metastasis,but is also crucial for clinical tumor diagnosis,treatment decision-making,efficacy monitoring and prognosis evaluation.Molecular probes,as functional substances that enhance imaging signals,play a crucial role in tumor boundary recognition.In this article,the basic concepts and research significance of boundarics in biomedicine and tumor boundarics in biomedicine were summarized firstly.Then a comprehensive review of the research progress in tumor boundary imaging molecular probes was provided,covering areas such as magnetic imaging,optical imaging,acoustic imaging,nuclear imaging,and multimodal imaging.The strategies to regulate the sensitivity,specificity,and safety of molecular probes through chemical structure modifications,conjugation with targeting ligands,and tumor microenvironment-responsive designs were emphasized.Finally,the research trends of molecular probes for tumor boundary imaging were analyzed,and the challenges faced in this field and the future research directions were discussed.

Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH). Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups. Results: The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05). Conclusion This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

Objective:To explore the association between mouth breathing (MB) and functional speech sound disorders (FSSDs) in children, aiming to establish a novel theoretical basis for FSSD interventions.Methods:Eighty-nine children with an FSSD aged 4-12 years formed the FSSD group, while eighty-five age-matched healthy children served as controls. Their clinical data were processed using independent sample t-tests and chi-square tests to test for any significant differences between the two groups in terms of gender, age, mouth breathing status, post-frenotomy condition, Mandarin exposure before age 4, and delayed speech onset. Multivariate logistic regressions were evaluated to identify risk factors for FSSD in such children and to seek any association between mouth brea-thing and FSSD.Results:The regression analysis identified the following risk factors for childhood FSSD, ranked by odds ratio ( OR) magnitude: mouth breathing (adjusted OR=22.168, 95% CI=7.849-62.608, P≤0.01), delayed speech onset (adjusted OR=20.091, 95% CI=4.812-83.878, P≤0.01), age (a protective effect) (adjusted OR=0.979, 95% CI=0.962-0.997, P≤0.05). Univariate analysis of mouth breathing and associated factors revealed significant associations of FSSD with mouth breathing (χ 2=52.15, P≤0.01) and delayed speech onset (χ 2=25.873, P≤0.01). Conclusions:The significant risk factors for childhood functional speech sound disorders are mouth breathing (showing the highest adjusted OR), delayed speech onset and age. These findings suggest that early screening and therapeutic interventions for mouth breathing should be clinically prioritized to minimize FSSD risk.

Objective:To explore changes in brain activity in patients with post-traumatic stress disorder(PTSD).Methods:A total of 40 participants involved in car accidents were included,and functional magnetic reso-nance imaging(fMRI)scans were collected within one week.Anxiety,depression,and personality assessments were conducted with the Hamilton Anxiety Scale(HAMA),Hamilton Depression Scale(HAMD),and Eysenck Person-ality Scale for Adult(EPQ).After two months,a second fMRI scan was conducted,and a PTSD diagnosis was made.Participants were divided into a trauma-exposed group(n=23)and a PTSD group(n=17)based on wheth-er they developed PTSD.Changes in brain functional activity between the trauma-exposed group and the PTSD group were compared using the percentage of amplitude fluctuation(perAF)method.Results:Compared to the trauma-exposed group,the PTSD group showed a decreased perAF value in the left hippocampus at 1 week,and de-creased perAF values in the right mid-cingulate gyrus and left postcentral gyrus at 2 months(P＜0.05).When comparing the PTSD group at different times,the perAF values in the left middle temporal gyrus and left medial su-perior frontal gyrus decreased at 2 months(P＜0.05).Correlation analysis revealed that PCL-5 scores were posi-tively correlated with EPQ Psychoticism(r=0.32,P=0.041),HAMA(r=0.35,P＜0.05),and HAMD(r=0.34,P＜0.05).Regression analysis found that higher scores of EPQ psychoticism(OR=11.79)and HAMA(OR=1.62)were risk factors for post-accident PTSD,while higher scores of EPQ extraversion(OR=0.32)were pro-tective factors.Conclusion:It suggests that patients with post-traumatic stress disorder may show decreased activity in the right middle cingulate cortex,left postcentral gyrus,left middle temporal gyrus,and left medial superior fron-tal gyrus within two months after the traumatic event.

The core pathological hallmark of neurodegenerative diseases (NDDs) is the aberrant aggregation and impaired clearance of pathological proteins. Valosin-containing protein (VCP) plays a pivotal role in maintaining intracellular protein homeostasis by regulating the ubiquitin-proteasome system and autophagy-lysosome pathway. Pathogenic mutations or dysfunction of VCP can trigger widespread protein clearance defects, leading to pathological protein aggregation and neuronal death, and consequently contributing to NDDs progression. This article reviews the molecular structure and functions of VCP, as well as the role of VCP mutations or dysfunction in pathogenesis of inclusion body myopathy with Paget's disease of bone and frontotemporal dementia, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis and Huntington's disease, so as to provide new strategies and directions for NDDs treatment.

This study presents prenatal diagnosis and genetic analysis of a pedigree with X-linked intellectual disability. A gravida at approximately 20 gestational weeks underwent prenatal diagnosis following non-invasive prenatal testing suggested sex chromosome abnormalities. Copy number variation (CNV) sequencing identified a 5.7 Mb duplication at Xp22.2p22.11 in the fetus, which initially classified as a variant of uncertain clinical significance. This duplication was inherited from the phenotypically normal mother, while paternal CNV results were normal. Genetic testing of four intellectually disabled family members revealed the identical 5.7 Mb duplication. Through expanded pedigree analysis, the pathogenicity classification of the Xp22.2p22.11 microduplication was upgraded to likely pathogenic. After comprehensive genetic counseling, the family elected pregnancy termination with informed consent.
