Objective: To investigate the factors influencing the co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia, so as to provide a data foundation and theoretical basis for developing targeted intervention measures. Methods: In September and October 2024, a stratified cluster random sampling method was employed to select 139 102 students from 539 schools across 12 leagues/cities and 103 banners/counties in Inner Mongolia Autonomous Region. Participants who were diagnosed with allergic rhinitis by a doctor at least once within one year and had a body mass index ≥ 28 kg/m 2 were considered to have comorbid conditions. Results: The coprevalence rate of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia was 6.4% (8 931 cases). Lasso-Logistic regression revealed that nonboarding status, higher maternal education, consuming high protein foods ≥1 time daily, occasionally or never eating breakfast, engaging in moderate to vigorous physical activity for ≥60 minutes on fewer than half of holidays, and having been exposed to second hand smoke in person within the past seven days were associated with higher odds ratios for co-prevalence of allergic rhinitis and obesity( OR = 1.23 , 1.22-1.63, 1.20, 1.19, 1.38, 1.35); being female, higher grade level, residence in flag/county/district areas, non only child status, never having consumed a full glass of alcohol, non hypertensive status, and households without pets were associated with lower co-prevalence risks ( OR =0.65, 0.67-0.77, 0.81, 0.87, 0.73, 0.41, 0.68) (all P <0.05). The ROC curve indicated an area under the curve of 0.64 for the predictive model, demonstrating satisfactory discriminatory ability. The calibration curve showed consistency between predicted and actual occurrence probabilities. Conclusions The co-prevalence of allergic rhinitis and obesity among primary and secondary school students in Inner Mongolia is closely associated with demographic characteristics, dietary behaviours, and lifestyle habits. Future prevention and control strategies should prioritize these factors to implement targeted interventions.

Objective To analyze the relationship between humoral immune characteristics and lymph node metastasis status in non-small cell lung cancer(NSCLC)patients,and its predictive value for prognosis.Meth-ods A total of 203 NSCLC patients who were admitted to the hospital from February 2022 to December 2023 were selected.They were divided into two groups,N0+N1 group(n=103)and N2+N3 group(n=100)based on their lymph node metastasis status.Another 100 healthy individuals who underwent physical examinations during the same period were selected as the control group.Clinical data from patients were collected and the propensity score matching method was utilized to match them in a 1∶1 ratio,with 64 cases in each group.A stratified regression model was used to analyze the relationship between humoral immune characteristics and different lymph node metastasis statuses in NSCLC patients.Univariate regression analysis and a multivariate Cox regression model were used to adjust for confounding variables and to explore the independent risk factors of humoral immune characteristics on the prognosis of NSCLC patients.The LOWESS method was used to analyze the two-dimensional curve relationship of continuous variables.The predictive efficacy of humoral im-mune characteristics was evaluated on the prognosis of NSCLC using the area under the receiver operating characteristic and under the curve(AUC).Results Compared with patients in the N0+N1 group,patients in the N2+N3 group had a higher proportion of tumor infiltration depth(T3+T4),high tumor differentiation,and clinical stage(Ⅲ+Ⅳ stage),as well as higher levels of IgA,IgM,IgG,C3,and C4(P＜0.05).Hierarchi-cal regression analysis revealed that IgA,IgM,IgG,C3,and C4 had a significant positive effect on different lymph node metastasis statuses in NSCLC patients(P＜0.05).Univariate and multivariate regression analy-ses revealed that elevated levels of IgA,IgM,IgG,C3 and C4 were independent risk factors for the prognosis of NSCLC(P＜0.05).LOWESS analysis revealed a non-linear relationship between the median overall survival(OS)of NSCLC patients and IgA,IgM,IgG,C3,and C4 levels.The humoral immune characteristics of IgA,IgM,IgG,C3 and C4 showed good predictive performance for the prognosis of NSCLC patients.Conclusion IgA,IgM,IgG,C3 and C4 are independent risk factors for the prognosis of NSCLC patients and demonstrate good predictive performance for the prognosis of NSCLC patients.

Purpose: There is still insufficient evidence for predicting stroke risk in patients with mild carotid atherosclerotic stenosis. This study aimed to explore the association between carotid intraplaque neovascularization (IPN) in mild stenosis and ischemic stroke, using contrast-enhanced ultrasound (CEUS) imaging. Methods: This retrospective observational study included 369 patients from July 2021 to March 2022. These patients were categorized as symptomatic or asymptomatic based on their recent history of ipsilateral ischemic stroke. Initial parameters of carotid plaques, such as IPN grading and contrast enhancement index, were assessed using B-mode ultrasonography and CEUS. The follow-up period lasted 12 months or until a newly-developed ischemic stroke occurred. Logistic regression models and Cox proportional-hazards regression models were employed to explore the associations between ultrasonic parameters and the incidence of recent and future ischemic strokes. Results: In patients with mild stenosis, both increasing age and grade 2 carotid IPN were significant predictors of recent primary ischemic stroke. Furthermore, grade 2 carotid IPN independently predicted future ischemic strokes in both symptomatic and asymptomatic patients. Conclusion This study demonstrated that carotid IPN as detected by CEUS imaging holds potential as a useful non-invasive biomarker for predicting recent and future ischemic strokes in patients with mild carotid stenosis.

Hemorrhagic shock is a common clinical emergency that can aggravate cell injury after resuscitation. Astrocytes are crucial for the survival of neurons because they regulate the surrounding ionic microenvironment of neurons. Although hemorrhagic shock and resuscitation (HSR) injury can impair cognition, it remains unclear how this insult directly affects astrocytes. In this study, we established an HSR model by bleeding and re-transfusion in mice. The social interaction test and new object recognition test were applied to evaluate post-operative cognitive changes, and the results suggest that mice experience cognitive impairment following exposure to HSR. In the HSR group, the power spectral density of β and γ oscillations decreased, and the coupling of the θ oscillation phase and γ oscillation amplitude was abnormal, which indicated abnormal neuronal oscillation and cognitive impairment after HSR exposure. In brief, cognitive impairment in mice is strongly correlated with Ca²⁺ signal strength in lateral septum astrocytes following HSR.

JMJD1C (Jumonji Domain Containing 1C), a member of the lysine demethylase 3 (KDM3) family, is universally required for the survival of several types of acute myeloid leukemia (AML) cells with different genetic mutations, representing a therapeutic opportunity with broad application. Yet how JMJD1C regulates the leukemic programs of various AML cells is largely unexplored. Here we show that JMJD1C interacts with the master hematopoietic transcription factor RUNX1, which thereby recruits JMJD1C to the genome to facilitate a RUNX1-driven transcriptional program that supports leukemic cell survival. The underlying mechanism hinges on the long N-terminal disordered region of JMJD1C, which harbors two inseparable abilities: condensate formation and direct interaction with RUNX1. This dual capability of JMJD1C may influence enhancer-promoter contacts crucial for the expression of key leukemic genes regulated by RUNX1. Our findings demonstrate a previously unappreciated role for the non-catalytic function of JMJD1C in transcriptional regulation, underlying a mechanism shared by different types of leukemias.

(+)-Strebloside, a significant bioactive compound isolated from the roots of Streblus asper Lour., demonstrates inhibitory effects against multiple malignancies. However, its specific function and underlying mechanistic pathways in Non-Hodgkin lymphoma (NHL) remain unexplored. This investigation sought to elucidate the role and potential mechanisms of (+)-strebloside-induced NHL cell death. The results demonstrated that (+)-strebloside significantly induced apoptosis and ferroptosis in NHL cells, including those from Raji cell-derived xenograft models. Mechanistic analyses revealed that (+)-strebloside enhanced six-transmembrane epithelial antigen of prostate 3 (STEAP3)-induced ferroptosis in NHL, and STEAP3 inhibition reduced the proliferation-inhibitory effects of (+)-strebloside. Furthermore, (+)-strebloside suppressed NHL proliferation through the mitogen-activated protein kinase (MAPK) pathway, and extracellular signal-regulated kinase (ERK) inhibition diminished the proliferation-inhibitory activity induced by (+)-strebloside. These findings indicate that (+)-strebloside presents promising therapeutic potential for NHL treatment.

Objective To investigate the efficacy of Castor branching stent in treating Stanford type B aortic dissection(TBAD)involving aortic arch.Methods The clinical data of 18 patients with Stanford TBAD,who were treated with Castor branching stent at the Suining Municipal Central Hospital of China from January 2020 to January 2022,were retrospectively analyzed.Results The main bracket and branch bracket of Castor branching stent were successfully released in all the 18 patients with a surgical success rate of 100％,and no internal leakage occurred during operation.During the perioperative period,there were neither aorta-related deaths nor serious complications such as stroke,upper limb ischemia,internal leakage,or stent displacement.The patients were followed up for(14.7±8.3)months,no aorta-related death,stroke,upper limb ischemia,internal leakage,or stent displacement was observed,the blood flow of the left subclavian artery(LSA)was unobstructed,but there was thrombosis formation within the false lumen of the covered stent segment.Conclusion The Castor branching stent has the advantages of reasonable release mode,accurate positioning,effective isolation of the first rupture of Stanford TBAD and reconstruction of LSA,with no serious short-term complications.However,further follow-up observation is needed before its long-term efficacy can be clarified.

Objective West Nile virus(WNV)is one of the most common mosquito-borne zoonotic viruses worldwide,with unique transmission dynamics and varied hosts.Lots of ecological and host factors have been reported to influence the host adaptation and transmission of WNVs,however,general genomic features of WNVs are less focused,except for some exact host-specific genotypes at molecular level.Artificial intelligence that analyzes genome composition characteristics currently shows significant advantages in identifying and predicting viral host adaptability.This research aimed to establish a convolutional neural network(CNN)model to predict the host adaptability of WNVs based on general genomic features.Methods Presently available WNV gene sequences were embedded for their genomic features with an embedding approach of dinucleotide composition representation(DCR).And DCR-based distribution difference of WNV samples among various hosts was performed with unsupervised learning methods.Then a classification model was built with a convolutional neural network(CNN)framework based on genomic DCR to evaluate the adaptation of the WNVs from birds,mammals and mosquitos.Additionally,host-specific amino acids in WNV proteins were inferred via Bayes method.Results DCR features could effectively distinguish host-specific WNVs.The trained CNN model predicted accurately mammalian susceptible WNVs from avian susceptible WNVs,however,much less accurately for mosquito/mammalian WNVs.Such predicted host adaptation was interpreted as host specified significance of biased amino acid distribution on the bayes-inferred sites in WNV proteins,implying a possible high significance of these sites for WNV adaptive phenotypes.Conclusions Genomic compositional features of WNVs are host-specific,and such genomic bias facilitates predicting the adaptation of WNVs to avian or mammalian hosts via deep learning methods.DCR-based decomposition is helpful to recognize the high risk of infecting mammals of WNVs.The present study provides a general knowledge of genomic features contributing to host adaptation to WNVs.

Objective To explore the intervention effect of the"5E"rehabilitation nursing model(Education,Encouragement,Evaluation,Exercise,and Employment)for patients with primary aldo-steronism(PA).Methods A total of 120 patients diagnosed as PA in the Cardiology Department of the Third People's Hospital of Qingdao from January 2022 to June 2024 were randomly divided into control group(n=60)and observation group(n=60).The control group received routine nursing in-tervention,while the observation group received the"5E"rehabilitation nursing intervention.Blood test indicators,clinical manifestations(blood pressure,fatigue level),score of quality of life,and nursing satisfaction rate were compared between the two groups.Results After intervention,blood so-dium,plasma aldosterone,blood creatinine,urea nitrogen,uric acid,systolic blood pressure,dias-tolic blood pressure,and scores of fatigue degree in the observation group were significantly lower than those in the control group,while blood potassium level and score of quality of life were significantly higher than those in the control group(P＜0.05).The nursing satisfaction rate in the observation group was 96.67％,which was significantly higher than 80.00％in the control group(P＜0.05).Conclusion Implementation of the"5E"rehabilitation nursing intervention during hospitalization for PA patients can improve their blood indicators and clinical symptoms,alleviate the severity of the dis-ease,and enhance their qualities of life.

Objective: To analyze the prevalence trends of different types of elevated blood pressure and their association with nutritional status among primary and secondary school students in Inner Mongolia from 2019 to 2024, providing references for targeted prevention strategies. Methods: From September 2019 to 2024, a stratified random cluster sampling method was used to select 12 primary and secondary schools from each league city in Inner Mongolia Autonomous Region. A total of 177 108, 137 758, 190 182, 180 084 , 188 056, 180 351 primary and secondary school students (excluding grades one to three of primary school) were included for physical examination. The correlation between their nutritional status and high blood pressure was analyzed based on the basic situation of 129 821 primary and secondary school students who completed a questionnaire survey at the same time in 2024. Statistical analysis was conducted using a Chi-square test and multiple Logistic regression model. Results: From 2019 to 2024, the detection rates of elevated blood pressure were 13.60%, 13.68%, 17.60%, 17.24%, 14.77% and 15.96%, respectively. The rates for isolated systolic hypertension were 4.24%, 5.83%, 7.26%, 7.19%, 6.24% and 6.93%; isolated diastolic hypertension rates were 6.38%, 4.99%, 6.23 %, 6.41%, 5.39% and 5.66%; and combined systolic and diastolic hypertension rates were 2.97%, 2.86%, 4.11%, 3.65%, 3.14 % and 3.36%. Multivariate Logistic regression analysis showed that girls, junior high school, senior high school, overweight, and obesity were positively associated with elevated blood pressure risk ( OR =1.27, 1.25, 1.32, 1.66, 3.07, all P <0.05); conversely, county residence, Mongolian ethnicity, and other ethnicities showed negative associations ( OR =0.90, 0.93, 0.90, all P <0.05). Conclusions Overweight and obesity among children and adolescents are closely related to various types of elevated blood pressure. Prevention strategies should prioritize effectively controlling weight issues among children and adolescents, thereby effectively reducing the incidence of elevated blood pressure.
