ObjectiveTo investigate the effects of lectin-like oxidized low-density lipoprotein receptor-1 （LOX-1） gene G501C on brain structure and cognitive function in patients with white matter hyperintensities （WMH）. MethodsA total of 118 patients with WMH were enrolled. All participants underwent T1-weighted and T2-fluid-attenuated inversion recovery （T2-FLAIR） MRI to assess gray matter structure and WMH burden， and completed the mini-mental state examination （MMSE） and Montreal cognitive assessment （MoCA）. Partial correlation and mediation analyses were performed to explore the impact of LOX-1 polymorphism on cognitive function. ResultsParticipants were divided into GG+GC group （n = 35） and CC group （n = 83）. The GG+GC group showed lower MMSE and MoCA scores （MMSE： P=0.003； MOCA： P=0.015）， as well as greater WMH burden （all P0.001）， compared with the CC group. Voxel-based morphometry （VBM） analysis revealed reduced left thalamic volume in the GG+GC group， which was correlated with cognitive scores （all P0.05）. Subregional thalamic analysis further showed volume reductions in the lateral， ventral， medial， and pulvinar thalamic regions （all P0.05） in the GG+GC group， all positively associated with cognitive performance （all P0.05）. Mediation analyses indicated that volumes of the medial and pulvinar thalamic regions mediated the association between genotype and cognitive function （MMSE， MoCA）， and that WMH volume mediated the effect on MoCA scores. ConclusionThe LOX-1 G501C polymorphism may indirectly affect cognitive function by influencing specific thalamic subregional volumes and white matter damage， suggesting a potential mediating role of thalamic structures between genetic background and cognitive impairment.

Objective:To explore the epidemiological characteristics, clinical manifestations, laboratory findings, and imaging features of children with HRV-associated pneumonia, and to analyze the clinical features and risk factors associated with severe HRV pneumonia, providing references for clinical management.Methods:A single-center, retrospective, observational study was conducted, including 1 001 cases of HRV-positive children with pneumonia admitted to the Respiratory Department of the Affiliated Children′s Hospital of Capital Institute of Pediatrics from January 2019 to December 2023. Among them, 584 cases (58.3%) were male and 417 cases (41.7%) were female, with an age range of 0.1 to 14.9 years, a median age of 3.42 years, and a mean age of (3.92±2.75) years. According to clinical guidelines, the cases were divided into a mild pneumonia group (855 cases, 510 males, 345 females) and a severe pneumonia group (146 cases, 73 males, 73 females). Basic information, clinical, laboratory, and imaging data were collected from the electronic medical record system. Comparisons between different age groups, diagnoses, and pneumonia severity groups were performed using the χ2 test. Multivariate logistic regression analysis was used to identify risk factors for the severity of HRV pneumonia. Results:Among the 1 001 cases of HRV-associated bronchopneumonia, 146 cases (14.6%) were severe pneumonia. The age of severe HRV pneumonia patients was significantly higher than that of the mild pneumonia group (5.2 years vs. 3.7 years, t=-6.050, P<0.01). Severe HRV pneumonia had a higher incidence in autumn and winter (60.9%). Severe HRV pneumonia was associated with higher levels of lactate dehydrogenase (LDH), C-reactive protein (CRP), neutrophils, and creatinine (correlation coefficients 0.198, 0.334, 0.104, 0.142, P<0.01), and lower levels of albumin (correlation coefficient 0.308, P<0.01). Multivariate logistic regression analysis showed that co-infection with Streptococcus pneumoniae or Mycoplasma was an independent risk factor for severe HRV pneumonia [ OR=1.611, 95% confidence interval ( CI):1.066-2.435, P<0.05; OR=3.355, 95% CI:2.062-5.458, P<0.01]. Conclusion:The infection rate of HRV is higher in preschool and school-age children. Severe HRV pneumonia is associated with increased levels of LDH, CRP, neutrophils, and creatinine, as well as decreased levels of albumin. Co-infection with Streptococcus pneumoniae or Mycoplasma may be an independent risk factor for severe HRV pneumonia. High-risk children require enhanced monitoring and early intervention to improve prognosis.

Objective:To analyze the effect and safety of tirofiban bridging combined with aspirin for anti-platelet therapy in patients with acute cerebral infarction (ACI) beyond the thrombolytic time window.Methods:Sixty patients with ACI treated in Beijing Royal Hospital from January 2021 to September 2022 were retrospectively analyzed. Among them, 30 cases were treated with tirofiban bridging aspirin as the observation group, while 30 cases were treated with aspirin alone as the control group. The total effective rate of clinical treatment, the degree of neurological deficit, the degree of disease outcome and the incidence of adverse reactions were compared between the two groups. The degree of neurological deficit was evaluated using the National Institutes of Health stroke scale (NIHSS), and the degree of disease outcome was evaluated using the modified Rankin scale (mRS).Results:The overall effective rate in the observation group was significantly higher than that in the control group: 93.3% (28/30) vs. 66.7% (20/30), with a statistically significant difference ( χ2 = 10.97, P<0.01). Before treatment, there was no statistically significant difference in NIHSS score between the two groups ( P>0.05). However, after treatment, the NIHSS score in the observation group was significantly lower than that in the control group: (2.83 ± 1.87) scores vs. (4.93 ± 3.05) scores, indicating a significant difference ( t = -3.21, P = 0.002). No significant difference was observed in mRS score between the two groups before treatment( P>0.05). After treatment, the observation group showed significantly lower mRS score compared to the control group: 2.00 (1.00, 2.00) scores vs. 3.00 (2.00, 4.00) scores ( P = 0.006). There was no statistical difference in the incidence of adverse reactions between the observation group and control groups ( P>0.05). Conclusions:Tirofiban bridging aspirin has stronger inhibitory effect on platelet activity than simple application of aspirin for ACI patients with ultra-thrombolytic window, which can rapidly improve the degree of neurological impairment and daily living ability of patients, and the incidence of adverse reactions has not increased significantly.

To explore the interaction between ASFV capsid protein M1249L and host from the host cellular perspective,M1249L was selected for constructing the bait plasmid(pGBKT7-M1249L)to screen the bone marrow-derived macrophages(BMDMs)cDNA library.After again co-transform and sequence alignment,20 candidate interacting host proteins were screened,such as IL-1β,CTSB and DNAJA3.And then,co-immunoprecipitation assay was performed to verify the interaction be-tween M1249L and host proteins.GO ontology(GO)and KEGG pathway enrichment analyses re-vealed that biological regulation,cellular communication and response to stimulus and others were enriched in biological processes.And these host proteins could share some pathways,including toll-like receptor signaling pathway and Nod-like receptor signaling pathway.Therefore,the results provides the theoretical basis for further research on the mechanism of ASFV M1249L in viral in-fection and immune regulation.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

The clinical application of antisense oligonucleotide (ASO) therapeutics faces significant challenges, particularly those related to immunogenicity. To address these issues, researchers have introduced chemical modifications to the nucleic acid backbone and terminal structures of ASOs, thereby markedly improving their in vivo stability, target specificity, and resistance to nuclease degradation. In addition, advances in delivery systems and administration strategies have effectively enhanced delivery efficiency, enabling ASOs to better meet diverse therapeutic requirements. This review provides an overview of recent progress in the development, delivery, and immunological aspects of ASOs, with the aim of offering insights into chemical modification, delivery efficiency, and stability, and ultimately promoting the further advancement of ASO therapeutics in disease treatment.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective To explore the mediating role of intolerance of uncertainty(IU)and moderating role of the negative emotion differentiation in the influence of perceived stress on anxiety among college students from a cognitive perspective.Methods A total of 271 participants were surveyed using the perceived stress scale,intolerance of uncertainty scale,depression anxiety and stress scale(Chinese version),and the test on negative emotional differentiation.SPSS 22.0 was used to perform descriptive statistics and correlation analyses and to test the moderated mediation model.Results Perceived stress affected anxiety and IU played a mediating role-perceived stress could affect anxiety through influencing IU.At the same time,the influence of IU on anxiety could be adjusted through the negative emotion differentiation.The higher the degree of negative emotion differentiation,the lower the degree of anxiety increase(β=0.17,t=5.70,P＜0.01).Conclusion It may be effective to develop training programs to reduce anxiety by regulating perceived stress,increasing acceptance of uncertainty,and improving the negative emotion differentiation,which can help individuals reduce anxiety by perceiving and adjusting anxiety-related emotional or cognitive factors in a timely manner.

Total laryngectomy is a crucial surgical intervention for patients with advanced malignant tumors of the larynx and nasopharynx. Despite its effectiveness, this procedure permanently severs the connection between the nasal cavity and the lower respiratory tract, leading to the cessation of nasal airflow. This disruption significantly impairs the patient's sense of smell and adversely affects their quality of life. Although olfactory loss is common in these patients, the assessment and rehabilitation of their olfactory function are often overlooked. This article reviews relevant literature on evaluating olfactory function and rehabilitation methods following total laryngectomy, with the aim of providing a theoretical foundation to enhance olfactory rehabilitation and overall quality of life for these patients.
