Uricase-based drugs excel at treating refractory hyperuricemia and tumor lysis syndrome by directly degrading uric acid but are limited by immunogenicity. Here, we engineered RAW264.7 macrophages with ectopic co-expression of Aspergillus flavus uricase and murine urate anion transporter 1 (URAT1), forming a “transport-degradation” system: URAT1 actively transports uric acid into cells for intracellular degradation. Recombinant lentiviral vectors carrying target genes were transfected into RAW264.7 cells, followed by puromycin screening. In vitro assays showed that the engineered macrophages nearly completely degraded uric acid (from 556.0 ± 37.0 μmol/L to 0.7 ± 0.6 μmol/L) at 72 h. URAT1 inhibition with benzbromarone abolished uric acid degradation in URAT1-expressing cells. In both acute dietary-induced and chronic genetic hyperuricemic mouse models, RAW-afUri-URAT1 exerted robust and sustained uric acid-lowering activity, maintaining serum uric acid at 77.14 ± 37.48 μmol/L on day 16 in yeast extract gavaged mice and normalizing serum uric acid to 76.2 ± 15.9 μmol/L in liver uricase conditional knockout mice, both significantly superior to the rebound levels observed in mice treated with Rasburicase (143.19 ± 38.21 μmol/L and 142.4 ± 17.4 μmol/L, respectively; PTo investigate the risk factors for primary non-central malposition of peripherally inserted central catheter (PICC) tip in neonates admitted to the neonatal surgical department, compare the malposition rates across different insertion sites in disease types, and explore whether different diseases affect PICC tip malposition.
A retrospective case–control study conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement.
A 3A women’s and children’s hospital in South China (Guangdong Province).
A total of 558 neonates aged ≤28 days who underwent PICC insertion between January 2019 and November 2024 were enrolled. Neonates with congenital circulatory system malformations, incomplete clinical data and death or treatment withdrawal before tip positioning were excluded.
The primary outcome was the incidence of primary non-central PICC tip malposition confirmed by X-ray or ultrasound within 24 h after insertion. Secondary outcomes included comparison of primary non-central PICC tip malposition rates across different insertion sites and comparison of primary PICC tip malposition rates by insertion sites across different disease groups.
558 neonates were included in this study, including 460 cases with PICC tip in place and 98 with PICC tip malposition. In binary logistic regression analysis, the PICC insertion site was considered an independent risk factor (OR 2.908, 95% CI 1.748, 4.840, p
Medical staff can choose appropriate upper or lower limb veins for PICC insertion without worrying about the impact of abdominal diseases or thoracic diseases on non-central PICC tip malposition. PICC insertion via the head and neck veins should be performed with caution in neonates, as these sites carry a high risk of primary non-central tip malposition compared with other insertion sites.

Acute pancreatitis (AP) is a severe inflammatory disorder in which pyroptosis—a pro-inflammatory form of programmed cell death—may contribute to pathogenesis. However, the complete transcriptional profile of pyroptosis-related genes (PRGs) in AP and their potential as diagnostic biomarkers remain underexplored. This study aimed to systematically characterize pyroptosis-associated transcriptional signatures and identify the reliable biomarkers for diagnostic purposes. Three transcriptomic datasets from murine AP models were integrated to identify pyroptosis-related differentially expressed genes (PRDEGs). Functional enrichment and immune cell infiltration analyses were conducted to elucidate the biological pathways and immune microenvironment alterations associated with these genes. mRNA-transcription factor (TF) and mRNA-microRNA (miRNA) regulatory networks were constructed to investigate underlying molecular interactions. Machine learning techniques, including support vector machine (SVM) and least absolute shrinkage and selection operator (LASSO), were applied for feature selection, leading to the identification of key diagnostic markers and the development of a logistic regression model. The regression model were then assessed using an independent cohort of human peripheral blood samples. Eleven PRDEGs were identified, with enrichment observed in processes such as cytoskeletal organization, cell-substrate adhesion, and critical inflammatory signaling pathways, including MAPK and NF-κB. Immune infiltration analysis revealed significant correlations between these PRDEGs and various immune cell subsets, particularly M1 macrophages, Treg cells, and monocytes. A four-gene diagnostic signature, comprising ANXA3, IQGAP1, RELA, and VTN, was established through SVM and LASSO analysis. In the independent human cohort, the fixed-coefficient four-gene model demonstrated reduced discrimination, which likely reflects interspecies and tissue-specific variations. However, after optimizing the model to exclude non-significant predictors, a refined two-gene signature (ANXA3 and IQGAP1) exhibited improved accuracy, with excellent calibration and clinical net benefit. This study offers a comprehensive transcriptomic analysis of the pyroptosis-mediated landscape and immune microenvironment in AP. An optimized two-gene signature, comprising ANXA3 and IQGAP1, was validated in a human cohort with superior accuracy, reflecting critical disruptions in inflammatory pathways and cytoskeletal organization. Notably, ANXA3 demonstrated potential for stratifying disease severity. Although these markers hold potential for molecular diagnosis, further prospective studies are essential to establish their clinical specificity and generalizability across diverse populations.by Hongtao Li, Li Xu, Longxin An, Xiaojing Li, Linjing Zhang, Jun Liu, Kaili Zhai, Xuecheng Sun, Naibo Feng
PurposeTo evaluate whether posterior column screws penetrate the posterior cortical surface of the acetabulum when assessed using obturator oblique radiographic imaging.
MethodsComputed tomography (CT) scans were performed on the right acetabulum of 50 healthy adults to measure the angle (α) between the posterior wall of the acetabulum and the sagittal plane at the level of the femoral head’s maximal diameter. In addition, five cadaveric pelvises were subjected to C-arm fluoroscopic imaging. A 6 cm long, 1.5 mm Kirschner wire was positioned along the posterior surface of the acetabular posterior column, aligned with the greater sciatic notch, and imaged in both the 45° and α-degree obturator oblique views. The radiographic line visualized from the Kirschner wire in the obturator oblique view was defined as the posterior iliac line, and its anatomical relationship with the posterior surface of the posterior column was analyzed. Subsequently, a 2.5 mm Kirschner wire was inserted into the posterior column at the standard entry point for screw placement using an electric drill, with the wire tip intentionally positioned between the posterior iliac line and the posterior rim in the 45° obturator oblique view. The trajectory of the wire was assessed under both 45° and α-degree obturator oblique views to determine its relation to the osseous corridor.
ResultsThe measured angle between the posterior surface of the acetabular posterior column and the sagittal plane was (60.2 ± 2.5)°. In the 45° obturator oblique view, the posterior iliac line corresponded with the outer edge of the iliac crest superiorly and the outer edge of the ischium inferiorly, while the posterior wall was projected posterior to the midpoint of the posterior iliac line. In the α° obturator oblique view, the posterior iliac line maintained this alignment but intersected centrally with the posterior acetabular wall. The 2.5 mm Kirschner wire remained within the osseous corridor under the 45° view but potentially extended beyond it under the α° view.
ConclusionWhen the posterior column screw is visualized posterior to the posterior iliac line in the 45° obturator oblique view, further assessment using a α° view is necessary. If the screw appears anterior to the posterior iliac line in the α° view, it indicates that the posterior cortical surface has not been breached.

ObjectiveThis study aimed to assess the incidence and risk factors for the development of steroid-induced ocular hypertension (SIOH) following 23-gauge (23G) pars plana vitrectomy.
MethodsThe clinical data of patients treated with 23G vitrectomy from January 2019 to March 2022 were reviewed retrospectively. The incidence and characteristics of SIOH post-operatively and treatment provided were recorded. The clinical risk factors for developing SIOH were analyzed using logistic regression analysis.
ResultsAmong the 540 eligible patients, 111 (20.56%) cases developed SIOH. The majority (83.78%) of the SIOH cases developed between the third and seventh day postoperatively. Among these cases, 65 (58.56%) patients had an intraoperative pressure (IOP) of 30 mmHg or higher, and 31 (27.9%) had an IOP of 40 mmHg or higher. The IOP of all SIOH patients returned to normal within 1 month following the discontinuation of steroid and IOP-lowering medicine treatment. The independent risk factors for SIOH (IOP ≥ 23 mmHg) were myopia (odds ratio (OR) 5.22) and silicone oil filling (OR 8.20). For severe SIOH (IOP ≥ 30 mmHg) myopia and silicone oil filling were also identified as risk factors with an OR of 3.23 and 12.86, respectively. After adjusting the steroid administration pattern, the incidence of all SIOH and severe SIOH decreased to 17.11% and 9.14%, respectively.
ConclusionsMyopia and silicone oil filling were identified as potential independent risk factors for the development of SIOH after vitrectomy. A shorter topical steroid therapy was associated with a lower incidence of SIOH particularly in high-risk patients.
To explore how chronically ill patients, family members and nurses perceive and experience patient participation in nursing care within a Chinese hospital context.
Focused ethnography.
The study was conducted in a Chinese public hospital over 8 months between February and September 2021. Data were generated through 90 h of participant observation and 30 semi-structured interviews, including individual and dyadic interviews with 10 nurses, 17 patients and 7 family members. Data were analysed using reflexive thematic analysis through an inductive and iterative process.
An overarching theme ‘participation as relational, holistic and dynamic’ was developed, comprising three themes: (1) participation as fulfilling individual responsibility, (2) family members as co-participants and (3) participation as an evolving multidimensional practice. These themes suggest that participation was understood as a relational responsibility enacted through everyday interactions. Family members were actively involved in care processes, and participation extended across physical, intellectual and emotional dimensions. Digital information and technologies further reshaped participation, creating new opportunities and tensions in everyday care.
Patient participation in nursing care extends beyond autonomy-based models and is shaped by relational responsibilities, family involvement and evolving digital healthcare contexts.
To promote patient participation, policies and practices should recognise relational and family-based dimensions of care. Healthcare organisations should foster environments that support collaborative participation among patients, families and nurses. Training and education should be developed to promote nurses' digital literacy, cultural competence, ethical sensitivity and relational communication to support participation in contemporary care contexts.
This study broadens prevailing autonomy-centred understandings of patient participation by demonstrating how participation is co-constructed through relational responsibilities and family involvement. The findings offer insights for nursing practice and policy in culturally diverse and increasingly digital healthcare environments.

Cardiac resynchronisation therapy (CRT) is a cornerstone device-based treatment for patients with heart failure with ventricular dyssynchrony. However, approximately 30–40% of recipients fail to achieve clinical response. Despite extensive research, validated prediction tools grounded in high-level evidence and readily applicable in clinical practice remain lacking. This study protocol describes the development and real-world validation of a simplified clinical scoring model for CRT response derived from systematic review and meta-analysis.
This study will develop a CRT response prediction model via meta-analysis and preliminarily validates it in a single-centre retrospective cohort. Initially, systematic searches of multiple databases up to 31 January 2026 and meta-analysis will synthesise effect estimates for candidate predictors, creating an evidence-based foundation that conceptually functions as a ‘training dataset’. Predictor selection and prioritisation will be guided by study frequency, effect magnitude and clinical accessibility, with factor weights derived directly from pooled random-effects meta-analytic estimates. Log relative risks will be converted to integer scores to establish a series of nested prediction models. Model performance will then be comprehensively assessed in an independent ‘validation dataset’ comprising a single-centre cohort from Xinjiang Medical University, evaluating discrimination (area under the receiver operating characteristic curve), calibration (calibration plots and Hosmer-Lemeshow test) and clinical utility (decision curve analysis). The final scoring system will be identified through comparative model evaluation guided by parsimony principles.
This meta-analysis exclusively uses published, de-identified data and therefore does not require ethical approval. The validation cohort employs retrospectively anonymised patient data in strict adherence to the ethical principles of the Declaration of Helsinki. The study protocol has been approved by the Institutional Review Board of the First Affiliated Hospital of Xinjiang Medical University (Approval No.: K202403-48-2503A-Y1). As this constitutes a retrospective analysis of existing data, individual informed consent will be waived. Comprehensive measures to protect participant privacy and ensure data integrity will be implemented throughout all research procedures. The findings will be presented at academic gatherings or published in scholarly, peer-reviewed journals.

To systematically review published studies on the post stroke delirium risk prediction models; and to provide the evidence for developing and updating the clinically available prediction models.
Systematic review.
Systematically searched studies on 10 databases, which were conducted from inception to 9 January 2025. The studies of post-stroke delirium risk prediction models were included.
Extracted the data from the selected studies. The Prediction Model Risk of Bias Assessment Tool checklist was used to evaluate the risk of bias of the models. The meta-analysis of model performance and common predictors was performed by Revman 5.4 and Medcalc.
A total of 12 studies were included, and 21 risk prediction models for post-stroke delirium were constructed. The combined effect size of area under the receiver operating characteristic curve was 0.84. All studies were found to have a high risk of bias and good applicability. Meta-analysis showed: National Institutes of Health Stroke Scale score, age, neutrophil-to-lymphocyte ratio, neglect, visual impairment and atrial fibrillation were independent predictors of post-stroke delirium.
The included studies all found to have a high risk of bias; future studies should focus on adopting more scientifically rigorous study designs and following the standardised reporting guidelines to enhance extrapolation and facilitate its clinical application.
This review may promote clinical healthcare workers to develop and update clinically available prediction models, thereby establishing risk prediction models with strong clinical utility.
This study presents the first systematic evaluation of delirium risk prediction models in stroke patients, thereby facilitating the choice, use and develop of the clinical usable post stroke delirium risk prediction models.

Advance care planning for people with dementia is an important process to ensure that patient preferences are respected throughout disease progression. However, the complexity of advance care planning and the challenges in effective communication hinder its implementation. The lack of clear procedural guidance for health care teams and the limited research on practical issues such as building trust and resolving conflicts further complicate this process.
To explore the key components of and processes for advance care planning for people with dementia.
The authors conducted a comprehensive search of databases, including PubMed, Embase, Web of Science, the Cochrane Library, CINAHL, NICE, Open Grey, CNKI, and Wanfang. The inclusion criteria focused on studies reporting advance care planning practices and stakeholder perspectives related to dementia.
The review included 45 studies and identified key components and processes for successfully implementing advance care planning in dementia care. These components include enhancing readiness, capturing patient wishes, and executing those wishes. The implementation processes cover assessing participation capacity, selecting surrogate decision-makers, and identifying healthcare providers who implement advance care planning. As the condition of people with dementia progresses, the role of healthcare providers who implement advance care planning becomes increasingly important in advance care planning practices.
The success of advance care planning depends on the interconnection of multiple components, and the findings offer practical insights for improving the advance care planning process to ensure that the care preferences of people with dementia are respected throughout the progression of the disease.

To classify the unmet integrated care needs of older adults with multimorbidity and to explore the factors associated with different categories of unmet integrated care needs among the target population.
A cross-sectional survey using the statistical method of latent profile analysis.
From July 2022 to March 2023, 397 older adults with multimorbidity, aged 60 years or older, were recruited from one primary healthcare setting and from four secondary and tertiary hospitals to participate in face-to-face questionnaire surveys. The questionnaire used in this study to assess unmet integrated care needs among older adults with multimorbidity was self-designed through a series of steps, including a scoping review, expert consultation and cognitive interviews. Latent profile analysis was applied to uncover distinct profiles of unmet integrated care needs, and multinomial logistic regression was employed to explore whether the profiles were further distinguished by participants' sociodemographic and health-related covariates. The data were analysed using IBM SPSS v.29.0 and Mplus v.8.0.
The optimal solution was a four-profile model, characterised by high unmet integration needs, high unmet system integration needs, low unmet system integration needs and low unmet integration needs, respectively. Multinomial logistic regression results indicated that profile differences were associated with place of residence, number of coresidents and the presence or absence of complex multimorbidity.
The integrated care needs of older adults with multimorbidity have not yet been fully met. Classifying and characterising unmet integrated care needs profiles is a crucial step in the rational allocation of integrated care resources.
This study was reported based on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) for cross-sectional studies.
All participants were older adults with multimorbidity, and they were informed that they could withdraw from the study at any time.
To explore the perceptions of patients with prostate cancer undergoing androgen deprivation therapy towards mobile health interventions.
The study employed a qualitative descriptive design.
Seventeen participants were recruited from tertiary care hospitals from November 2022 to June 2023. The collected data were subsequently analysed using a content analysis approach.
The main themes were facilitators, barriers, information needs, emotional and social needs, and self-management needs. Facilitators for using mobile health included support from healthcare professionals and family, competitive design features and user-friendly interfaces. Barriers included negative past experiences with technology and a satisfactory current state of health. Informational support included those patients who expressed a desire for timely, accurate information integrated with traditional Chinese medical principles. Regarding emotional support, patients emphasised their independence, preferring not to burden family and friends, showing disinterest in mindfulness and relaxation therapies, and generally disliking online interactions with fellow patients. For self-management, medication reminders and rehabilitation guidance were seen as vital tools to enhance supportive care.
The study highlights the importance of customising mobile healthcare applications to meet unique needs among patients with prostate cancer and enhance their engagement and satisfaction. Understanding their specific preferences enables the development of more effective mobile healthcare applications.

Lateral violence is a global social problem that has attracted considerable attention in the field of public health. This has seriously affected the quality of care, the safety of patients' lives and the career development of nurses.
To systematically evaluate the factors influencing of nursing lateral violence and provide evidence for preventing and reducing inter-nursing lateral violence.
A systematic review of qualitative study was performed in accordance with the Enhancing Transparency in Reporting the Synthesis of Qualitative Research (ENTREQ) guidelines. We collected qualitative studies on the factors influencing of inter-nursing lateral violence by searching PubMed, EMbase, The Cochrane Library, Web of Science, CINAHL, Science Direct, WanFang Data, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP) and Chinese Biomedical Literature Database (CBM). Data from inception to September 2023. Literature screening and data extraction were independently conducted by two reviewers. The Critical Appraisal Skills Program (CASP) scale was employed to assess the quality of the studies, including objectives, methodologies, designs, results and contributions.
A total of 25 studies involving 882 participants were included. The results of the thematic analysis indicated that inter-nursing lateral violence was influenced by hospital management, perpetrators, victims and sociodemographic factors.
Inter-nursing lateral violence was influenced by multidimensional factors. To reduce the occurrence of horizontal violence among nurses, hospitals need to explore the establishment and improvement of a horizontal violence resolution mechanism, and schools should pay attention to the joint support and education of nursing students, create a good working environment and harmonious nursing culture, and promote mutual respect among nurses.
This review emphasises the importance of the influencing factors of horizontal violence among nurses, analyses the importance of influencing factors from different perspectives, and proposes corresponding measures to reduce inter-nursing lateral violence.
This study was mostly a literature review; neither patients nor pertinent staff were involved in either the design or conduct of the investigation.

Nasopharyngeal carcinoma is prevalent in Thailand, with a substantial proportion of cases diagnosed at advanced stages. The standard treatment, concurrent chemoradiotherapy, is associated with considerable adverse effects, which may compromise therapeutic efficacy and diminish patients’ quality of life. While vitamin C has shown potential in reducing chemotherapy-induced toxicities in some cancers, its effects in nasopharyngeal carcinoma remain unclear. In this randomized, double-blind, placebo-controlled trial, patients with nasopharyngeal carcinoma undergoing concurrent chemoradiotherapy were assigned to receive either 2 g of intravenous vitamin C or placebo prior to chemotherapy. The incidence of gastrointestinal adverse effects—including nausea, anorexia, mucositis, diarrhea, and dysphagia—did not differ significantly between groups. However, longitudinal analysis demonstrated a significantly attenuated decline in platelet counts in the vitamin C group compared with placebo. Although intravenous vitamin C did not reduce gastrointestinal toxicities, the observed platelet preservation suggests a potential supportive effect that warrants further investigation. Trial registration The study was registered with the Thai Clinical Trial Registry (TCTR20190316003) on March 16, 2019.by Qin Zhang, Yuhong Hu, Xiaoju Li
With the rapid development of information and communication technologies, modern fire rescue models are evolving towards informatization, proactivity, and spatialization. Existing fire simulation models primarily focus on the impact of individual building parameters, lacking a systematic analysis of the multi-factor coupling effects on fire spread. As a result, it is difficult to accurately predict the trend of fire spread and meet the demands of dynamic escape routes for three-dimensional rescue systems. In this study, a typical L-shaped building was used as the research object, and a parameterized fire scenario database was constructed using the FDS (Fire Dynamics Simulator) fire simulation software, combined with experimental data for multi-factor coupling analysis. By simulating various factors such as initial fire locations (stairwell or corridor corner), floor height of ignition (low/mid/high area), and wind direction, this study systematically reveals the dynamic evolution process of smoke diffusion and the spatial distribution characteristics and interaction mechanisms of fire smoke in indoor and outdoor three-dimensional spaces. It also focuses on the time-dependent variations of smoke propagation in indoor escape routes, staircases, and external walls. The results indicate that the L-shaped building causes asymmetric smoke diffusion. The fire spread mode is a result of multi-factor coupling effects at the fire scene. Safe evacuation decisions are directly related to fire spread characteristics, smoke diffusion paths, the location of trapped individuals, fire alarm occurrence time, and rescue methods. Minor changes in each parameter can lead to significant differences in evacuation outcomes. Based on the situation at the site, generating real-time, dynamic escape paths is a crucial guarantee for improving rescue efficiency and success rates. The findings provide scientific support for the design and optimization of human-machine collaborative rescue systems and offer a data foundation for fire risk assessment and emergency response planning.Patient and Observer Scar Assessment Scale Version 3.0 (POSAS 3.0) is a robust instrument for scar evaluation. Currently, no validated POSAS 3.0 in the Malay language is available. This study aimed to translate, culturally adapt, and psychometrically evaluate POSAS 3.0 for Malay-speaking populations in Malaysia. Malaysian patients were recruited between 31 October 2023, to 31 December 2024. Translation was conducted using a forward and backward translation approach. Reliability was assessed using internal consistency (Cronbach's alpha) and test–retest. Face validity was addressed with 10 patients, and content validity was evaluated by four clinical specialists. Content validity was evaluated using the item-content validity index (I-CVI) and content validity ratio (CVR). Construct validity was assessed using exploratory factor analysis (EFA). Seventy-eight participants with facial (n = 39, 50.0%) and non-facial (n = 39, 50.0%) soft tissue scars were recruited for the EFA. The Malay POSAS-O demonstrated acceptable internal consistency (α = 0.75) and excellent inter-rater reliability, with item-level intraclass correlation coefficient (ICCs) ranging from 0.91 to 1.00 and total score ICC of 0.99. Agreement for categorical scar severity ratings was almost perfect (κ = 0.89). The Malay POSAS-P showed excellent internal consistency (α = 0.89), and test–retest reliability for the total score was good to excellent (ICC = 0.89). Intermittent symptom items (painful, shooting, burning and fragile) exhibited lower stability, reflecting natural symptom variability. Content validity was excellent, with all items achieving I-CVI and CVR values of 1.00. EFA supported construct validity, with adequate Kaiser-Meyer-Olkin (KMO) values (POSAS-O: 0.88; POSAS-P: 0.85), significant Bartlett's tests, strong communalities and factor loadings. The cumulative variance explained was 79.05% for POSAS-O and 68.19% for POSAS-P. The Malay version of the POSAS 3.0 is a reliable, valid, and culturally appropriate instrument for scar assessment. Its strong psychometric properties support its application in clinical practice and research involving Malay-speaking populations.
Spirituality is a crucial yet complex element of holistic nursing care, particularly when providing care for older adults with depression. In Thailand, depression poses a significant mental health challenge. Thai cultural values are deeply interwoven with individuals' beliefs, making spirituality a critical factor in addressing the care of older adults with depression. This study aimed to explore how older adults with depression experience spirituality and construct meaning from it in their daily lives.
An interpretative phenomenological study.
In-depth interviews of 30 older Thai adults living with depression (aged 60–85 years) from an outpatient psychiatric clinic in southern Thailand were conducted using semi-structured interview questionnaires. Interpretive phenomenological analysis was employed. Data were collected from June to August 2024.
Five themes emerged from the phenomenological data analysis: (1) elusiveness of spiritual meaning, (2) holding oneself together through inner power, (3) finding acceptance through faith in a higher power, (4) family ties shaping peace and despair, and (5) being guided and cared for.
This study highlights that older adults with depression perceive spirituality as essential for their well-being. Personal practices, such as meditation and chanting, played a key role in strengthening spirituality and reducing the risk of relapse in depressive symptoms, which are distinct for each older adult. Understanding spirituality's role in mental health guides nurses to develop strategies for providing more empathetic spiritual care.
Nurses must address depression in older adults through individualized practices to effectively empower their inner strength and coping mechanisms. Understanding each individual's spiritual practices is essential to help them harness their inner strength when coping with depression.

This study aimed to investigate the therapeutic effects of ELASEM®Flex and ELASEM®ProFlex, two eggshell membrane (EM) products, on sodium iodoacetate (MIA)-induced osteoarthritis (OA) in rats. An OA model was established by a single intra-articular injection of MIA into the knee joint. After modeling, rats were administered diclofenac sodium, ELASEM®Flex, and ELASEM®ProFlex by gavage daily for 4 consecutive weeks. During the experiment, food intake, water intake, body weight, and plantar mechanical pain threshold (MPT) of rats were measured weekly. Serum levels of TNF-α, COX-2, IL-1β, and CTX-II were assessed at weeks 2 and 4. After 4 weeks, knee joints were harvested for histopathological examination (HE staining and Safranin-O fast green staining). Results indicated that knee joints of OA rats showed significant swelling, which was alleviated to varying degrees in all treatment groups. Both ELASEM®Flex and ELASEM®ProFlex significantly increased the MPT (P ®Flex and ELASEM®ProFlex can exert preventive and reparative effects on knee OA in rats by alleviating arthritis pain, inhibiting inflammatory factor expression, reducing type II collagen degradation, and promoting chondrocyte proliferation.This study aims to explore the history of prior abortions and the factors influencing them among young women seeking abortion services in Foshan, Guangdong, China.

Approximately one-third of US adults have tattoos, yet the dosimetric impact of intradermal tattoo pigments during radiation therapy remains uncharacterized. Commercial tattoo inks contain unregulated metallic impurities including chromium, lead, and nickel, raising concerns about dose perturbations in tattooed skin. This work quantifies radiation dose perturbations induced by high-atomic-number (Z) tattoo pigments under clinically relevant radiotherapy conditions. Monte Carlo simulations (TOPAS) modeled layered skin phantoms with a 0.3-mm intradermal tattoo layer embedded at 1.25–1.55 mm depth. Three commercial inks were evaluated: carbon-based (black) and metal-containing (Fe-rich brown, Al-containing orange) at pigment loadings of 5–100 vol% within the tattoo layer, to establish upper-bound effects. Electron (6, 18 MeV) and photon (6, 18 MV) beams were simulated with standard clinical geometry (1 × 1 cm² field, SSD = 100 cm). Photon irradiation produced pronounced, depth-localized dose enhancement, with peak dose enhancement factor (DEF) reaching 2.5 for brown ink at 18 MV, a 62% mean increase relative to non-tattooed skin driven by high-Z–mediated secondary electron production. Electron beams exhibited energy-dependent behavior: 6 MeV produced modest enhancement (peak DEF ~ 1.07), while 18 MeV unexpectedly generated dose deficits (DEF
