Background/Aims:
The purpose of this study was to develop a diagnostic model utilizing multimodal ultrasound parameters to aid in the detection of cervical lymph node metastasis in papillary thyroid cancer (PTC) patients.
Methods:
The study included 84 suspicious lymph nodes from 69 PTC patients, all of whom underwent fine needle aspiration with pathological results. Data from conventional grayscale ultrasound, shear wave elastography (SWE), and superb microvascular imaging were analyzed. Key ultrasound features were compared between benign and metastatic groups to create a diagnostic model using Fisher’s stepwise discriminant analysis. The model’s effectiveness was assessed with self-testing, cross-validation, and receiver operating characteristic curve analysis.
Results:
Four features, namely lymphatic hilum (X1), cortical hyperechogenicity (X2), vascular pattern (X4), and SWEmean (X7), were integral to the discriminant analysis, resulting in the equation: Y1 = -3.461 + 2.423X1 + 0.321X2 + 1.620X4 + 0.109X7, Y2 = -8.053 + 0.414X1 + 2.600X2 + 2.504X4 + 0.192X7. If Y1 < Y2, the LN would be diagnosed as metastatic lymph nodes. The model demonstrated an area under the curve of 0.833, with a sensitivity of 83.33% and specificity of 83.33%.
Conclusions
The multimodal ultrasound diagnostic model, established through Fisher’s stepwise discriminant analysis, proved effective in identifying metastatic lymph nodes in PTC patients.

Immune checkpoint inhibitors (ICIs) have been approved for the treatment of a variety of solid tumors and hematological malignancies. Adverse reactions caused by ICIs have been gradually focused on. Cytomegalovirus (CMV) gastritis after ICIs treatment is relatively rare. Here we reported a case of advanced lung adenocarcinoma who experienced recurrent upper abdominal pain and vomiting after Pembrolizumab treatment. CMV gastritis was diagnosed through gastroscopy. The patient's symptoms improved after antiviral treatment. During the treatment of ICIs, attention should be paid to the differential diagnosis of upper abdominal pain symptoms, and vigilance should be maintained against CMV gastritis. It is difficult to differentiate CMV gastritis and immune-related gastritis judging from symptoms, and gastroscopy is important for differential diagnosis.

OBJECTIVE:
To investigate the effect of zedoarondiol on neovascularization of atherosclerotic (AS) plaque by exosomes experiment.
METHODS:
ApoE-/- mice were fed with high-fat diet to establish AS model and treated with high- and low-dose (10, 5 mg/kg daily) of zedoarondiol, respectively. After 14 weeks, the expressions of anti-angiogenic protein thrombospondin 1 (THBS-1) and its receptor CD36 in plaques, as well as platelet activation rate and exosome-derived miR-let-7a were detected. Then, zedoarondiol was used to intervene in platelets in vitro, and miR-let-7a was detected in platelet-derived exosomes (Pexo). Finally, human umbilical vein endothelial cells (HUVECs) were transfected with miR-let-7a mimics and treated with Pexo to observe the effect of miR-let-7a in Pexo on tube formation.
RESULTS:
Animal experiments showed that after treating with zedoarondiol, the neovascularization density in plaques of AS mice was significantly reduced, THBS-1 and CD36 increased, the platelet activation rate was markedly reduced, and the miR-let-7a level in Pexo was reduced (P<0.01). In vitro experiments, the platelet activation rate and miR-let-7a levels in Pexo were significantly reduced after zedoarondiol's intervention. Cell experiments showed that after Pexo's intervention, the tube length increased, and the transfection of miR-let-7a minics further increased the tube length of cells, while reducing the expressions of THBS-1 and CD36.
CONCLUSION
Zedoarondiol has the effect of inhibiting neovascularization within plaque in AS mice, and its mechanism may be potentially related to inhibiting platelet activation and reducing the Pexo-derived miRNA-let-7a level.

Objective:To investigate the sleep characteristics and clinical features of patients with vestibular migraine(VM), and to explore the influencing factors of sleep disorder in VM patients. Methods:A cross-sectional study method was adopted to collect VM patients from Otolaryngology department and neurology department of our hospital from June 2022 to June 2024(divided into sleep disorder group and non-sleep disorder group according to whether there is sleep disorder) as the experimental group, and recruit non-VM volunteers with clinical characteristics matching with the experimental group during the same period as the control group. The clinical data of the subjects were collected, and the sleep quality of the subjects was assessed using the Pittsburgh Sleep Quality Index(PSQI). The influencing factors of sleep disorders in VM patients were analyzed by multivariate Logistic regression, and the correlation between sleep disorders and clinical features such as headache, vertigo and hearing in VM patients was analyzed by Spearman correlation coefficient. Results:A total of 530 individuals with VM were analyzed, including 332 with sleep disturbances(62.64%), 198 without sleep issues(37.36%), and 50 in the control group. The overall PSQI score and all its components were significantly higher in the VM group compared with the control group(P<0.05). A positive correlation was observed between PSQI and VAS, DHI-T, DHI-E, DHI-F and DHI-P(r=0.797, P<0.05; r=0.834, P<0.05; r=0.794, P<0.05; r=0.771, P<0.05; r=0.877, P<0.05), PSQI had no correlation with pure tone hearing(r=0.324, P=0.167). Multivariate logistic regression analysis showed that female, age ≥60 years, living alone, duration of disease ≥3 months, motion sickness history, and HADS-A were independent influencing factors for comorbidification of sleep disorder in VM patients(P<0.05). Conclusion:The prevalence of sleep disorders in patients with vestibular migraine(VM) was significantly higher compared to the control group. Moreover, the severity of sleep disorders was positively correlated with the intensity of headache and vertigo in VM patients. It is recommended that female VM patients aged 60 years or older, living alone, with a disease duration of three months or longer, a history of motion sickness, and anxiety symptoms undergo sleep assessments to determine the presence of sleep disorders. This approach provides a theoretical foundation for precise treatment and prevention strategies for VM.

Allergen-specific immunotherapy(AIT) remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis(AR). Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group(CRRCG) convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Schwann cells and macrophages are the main immune cells involved in peripheral nerve injury. After injury, Schwann cells produce an inflammatory response and secrete various chemokines, inflammatory factors, and some other cytokines to promote the recruitment and M2 polarization of blood-derived macrophages, enhancing their phagocytotic ability, and thus play an important role in promoting nerve regeneration. Macrophages have also been found to promote vascular regeneration after injury, promote the migration and proliferation of Schwann cells along blood vessels, and facilitate myelination and axon regeneration. Therefore, there is a close interaction between Schwann cells and macrophages during peripheral nerve regeneration, but this has not been systematically summarized. In this review, the mechanisms of action of Schwann cells and macrophages in each other's migration and phenotypic transformation are reviewed from the perspective of each other, to provide directions for research on accelerating nerve injury repair.

To fully exploit Transformer for accurate registration,self-similarity context is used as a feature extractor to extract the semantic information of the voxel neighborhood context,using symmetric multi-scale discrete optimization with diffusion regularization to find smooth transformations for quickly calculating the point-by-point distance between descriptors.In addition,a spatial-channel Transformer based on window attention network is proposed,which combines channel,spatial attention and self-attention scheme based on(moving)window,and makes full use of the complementary advantages of these 3 attention mechanisms,enabling the network to utilize global statistical information and have strong local fitting ability.The results of comprehensive experiments on 3D brain MRI datasets of LPBA40,IXI and OASIS shows that the proposed method is superior to the commonly used registration methods(SyN,VoxelMorph,CycleMorph,ViT-V-Net and TransMorph)on several evaluation indicators,proving its effectiveness in deformable medical image registration.

The nucleophosmin 1(NPM1)muta-tion is one of the most frequent subtypes in acute myeloid leukemia(AML).Under the conditions of FLT3-internal tandem duplications(FLT3-ITD)and/or DNMT3A co-mutations or adverse cytogenetics,the originally favorable prognosis will deteriorate.In recent years,studies have found that multiple endocrine neoplasia protein(Menin)inhibitors tar-geting Menin-KMT2A complex can downregulate the overexpression of leukemia causing genes HOX(homeotic gene)and MEIS1(myeloid ecotropic vi-ral integration site 1)in NPM1-mutated AML,dem-onstrating remarkable anti-leukemia activity.This article aims to review the mechanism and clinical research of Menin inhibitors,novel small molecule targeted drugs in NPM1-mutated AML,as well as the resistance mechanism of Menin inhibitors,hop-ing to provide promising approaches for the subse-quent treatment of NPM1-mutated AML patients.
