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.

ObjectiveTo investigate the mechanisms of Runmu Dihuang decoction （RMDHD） in treating perimenopausal dry eye with liver-kidney Yin deficiency syndrome based on the silent information regulator 3 （SIRT3）/hypoxia-inducible factor-1α （HIF-1α）/nuclear factor-κB （NF-κB） signaling pathway. MethodsSixty female Sprague-Dawley rats were randomly divided into six groups （n=10 per group）： Sham operation group， model group， sodium hyaluronate eye drop group， and low-， medium-， and high-dose RMDHD groups （5.625， 11.25， 22.50 g·kg^-1）. Except for the sham operation group， all rats underwent bilateral ovariectomy and were administered 0.1% benzalkonium chloride eye drops combined with long-term chronic irritation to establish a perimenopausal dry eye model with liver-kidney Yin deficiency syndrome. Drug administration began in the 11th week after modeling and continued for 21 days. General conditions， screen-grip test scores， tear secretion volume， tear film breakup time （TFBUT）， and corneal fluorescein staining were recorded. Serum levels of reactive oxygen species （ROS）， follicle-stimulating hormone （FSH）， estradiol （E₂）， and progesterone （PROG） were measured by enzyme-linked immunosorbent assay （ELISA）. Pathological changes in the lacrimal glands， corneas， and uteri were observed using hematoxylin-eosin （HE） staining. Protein expression levels of SIRT3， HIF-1α， phosphorylated NF-κB p65 （p-NF-κB p65）， and total NF-κB p65 in the lacrimal glands were detected by Western blot. The expression of inflammatory cytokines interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α） in the lacrimal glands was assessed by immunohistochemistry （IHC）. ResultsAfter model establishment， no significant differences were observed among the groups except the sham operation group. Compared with the sham operation group， the other groups exhibited slowed movement， dull responses， increased irritability， reduced body weight， elevated rectal temperature， decreased screen-grip test scores， reduced tear secretion， and significantly shortened TFBUT （P<0.05）. After treatment， compared with the model group， the sodium hyaluronate eye drop group and all RMDHD groups showed improved general conditions， significantly increased tear secretion （P<0.05）， prolonged TFBUT （P<0.05）， and elevated screen-grip test scores （P<0.05）. Serum ROS and FSH levels were significantly decreased， while E₂ and PROG levels were significantly increased （P<0.05）. Pathological damage to the cornea， lacrimal glands， and uterus was ameliorated. In addition， protein expression levels of SIRT3 and HIF-1α in the lacrimal glands were significantly upregulated （P<0.05）， whereas the expression of p-NF-κB p65， IL-1β， and TNF-α was significantly downregulated （P<0.05）. ConclusionRMDHD increases tear secretion and TFBUT， improves lacrimal gland and corneal injury， and alleviates dry eye symptoms in a perimenopausal dry eye rat model with liver-kidney Yin deficiency syndrome. The underlying mechanism may be related to regulation of the SIRT3/HIF-1α/NF-κB signaling pathway， inhibition of oxidative stress and inflammatory responses， and reduction of ocular surface tissue damage.

Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

Abnormal synaptic plasticity is an early pathological feature of Alzheimer disease (AD). Synaptic damage and dysfunction initiate neuronal degeneration and death, ultimately leading to cognitive impairment. Traditional Chinese medicine (TCM) can effectively ameliorate cognitive dysfunction through multitarget regulation of synaptic plasticity. This review summarizes the mechanisms by which TCM, including active components, single herbs, and classical formulas, modulates synaptic plasticity, offering new insights for future research and clinical applications. Relevant experimental studies published between 2020 and 2024 were retrieved from major databases, including China National Knowledge Infrastructure, the National Science and Technology Library, Wanfang Data, Elsevier, ScienceDirect, PubMed, SpringerLink, and Web of Science. Network pharmacology and bioinformatics approaches were used to predict the therapeutic effects and mechanisms of TCM on AD-related synaptic plasticity. In total, 15 TCM single herbs and 11 TCM formulas were identified as enhancing AD-related synaptic plasticity. Additionally, 15 active ingredients targeting synaptic plasticity in AD were retrieved from TCM databases over the past decade. This review provides novel perspectives and strategic directions for future AD research and therapeutic development.

ObjectiveTo compare the differences in color， odor， coumarin content and microbial community composition of Angelicae Dahuricae Radix（ADR） during different drying processes， and to explore the correlation between changes in microbial community composition and changes in quality indexes of ADR. MethodsThe fresh ADR was processed at three drying temperatures（50， 70， 100 ℃） by drying and steaming cutting， semi-fresh cutting and drying， fresh cutting and drying， and sulfur fumigation methods. The color values of samples were extracted by Adobe Photoshop 2022 software and subjected to principal component analysis（PCA）， electronic nose was used to identify the odor information of medicinal powders and subjected to loadings analysis， PCA， and linear discriminant analysis（LDA）， and high performance liquid chromatography（HPLC） was used to determine the contents of five coumarins（bergapten， oxypeucedanin， imperatorin， phellopterin， isoimperatorin）. The samples for microbial detection were taken from fresh dried samples， 50 ℃（dried and steamed cut， sulfur fumigated） samples， and 100 ℃（dried and steamed cut） samples when the water content was 50% and 14%， respectively. And the changes of microbial community composition during processing were determined by high-throughput sequencing method. The relationship between the changes of microbial community composition and the changes of odor， color and active component content of ADR during drying process was analyzed by Pearson correlation analysis. ResultsThe color quantification results showed that an increase in drying temperature led to the decrease of brightness value（L）， and the increases of red-green value（a） and yellow-blue value（b）， and the change of processing method had no obvious effect on the color of medicinal materials. The results of odor quantification showed that W1S， W2S， W5S， W2W and W1W sensor were sensitive to the odor changes of ADR and could be used to distinguish ADR decoction pieces from different processing methods. The results of HPLC showed that the coumarin content of ADR decreased with the increase of drying temperature and the delay of processing time， the optimal processing method was drying and steaming cutting method， and the optimal temperature was 50 ℃. High-throughput sequencing results showed that the dominant bacteria in ADR during processing were Achromobacter， Agrobacterium， Nocardioides， Mycobacterium and Enterobacter， the dominant fungi were Coprinopsis， Meyerozyma and Apiotrichum. The results of correlation analysis showed that the quality indexes of ADR were positively correlated with Agrobacterium， Mycobacterium in bacteria， Candida in fungi， and negatively correlated with Bacillus in bacteria. ConclusionThere are significant differences in the color， odor， coumarin content and microbial community composition of ADR in different drying processes， and the best drying method is drying and steaming cutting at 50 ℃. The relative abundance changes of 9 bacterial genera and 4 fungal genera are closely related to the quality formation of ADR during the drying process.

Objective:To investigate the protective effect of achyranthes bidentata(AB)on sperm quality in mice with sper-matogenic disorder through the glycolytic metabolic pathway and its action mechanism.Methods:We equally randomized 40 Kun-ming mice into a normal control,a model control,a low-dose AB(3.5 g/kg)and a high-dose AB group(7.0 g/kg),and established the model of spermatogenic disorder in the latter three groups of mice by intraperitoneal injection of doxorubicin(30 mg/kg).Two days after modeling,we collected the testis and kidney tissues and blood samples from the mice for observation of the pathological changes in the testis tissue by HE staining,detection of perm motility with the sperm quality analyzer,examination of the apoptosis of testis cells by flow cytometry,measurement of the levels of testosterone(T),malondialdehyde(MDA),superoxide dismutase(SOD)and cata-lase(CAT)in the serum and testis tissue by ELISA,and determination of expressions of the key enzymes of glycolysis hexokinase Ⅱ(HK2),pyruvate kinase M2(PKM2),platelet phosphofructokinase(PFKP),lactate dehydrogenase A(LDHA)and the meiosis pro-teins REC8 and SCP3 by Western blot,and the mRNA expressions of glycolytic phosphofructokinase 1(PFK1),phosphoglycerate ki-nase 1(PGK1),tumor necrosis factor-α(TNF-α)and interleukin-1 β(IL-1β)by fluorescence quantitative PCR(FQ-PCR).Results:Compared with the model controls,the mice in the AB groups showed significant increases in the testis coefficient,kidney in-dex,sperm concentration,sperm motility,spermatogonia,primary spermatocytes,spermatids,sperm count and the serum T level(P＜0.05 orP＜0.01),but dramatic decreases in the apoptosis of testis cells and percentage of morphologically abnormal sperm(P＜0.01).Achyranthes bidentata also significantly elevated the levels of SOD and CAT,and down-regulated the mRNA expressions of MDA,TNF-α and IL-1β(P＜0.05 or P＜0.01),and up-regulated the protein expressions of HK2,PKM2,PFKP,LDHA,REC8 and SCP3,and expressions of the glycolysis key genes Pfk1 and Pgk1(P＜0.05 orP＜0.01).Conclusion:Achyranthes bidentata ameliorates doxorubicin-induced spermatogenic disorder in mice by regulating the glycolytic pathway and reducing oxidative stress and the expressions of inflammatory factors.

Objective:To study the relationship between microRNA (miRNA, miR)-675-3p, miR-675-5p, miR-29b-3p, miR-let-7b-3p and fluoride induced articular cartilage injury in rats.Methods:Using the factorial design, thirty 3-week-old specific pathogen free grade male Wistar rats (weighted 125 - 150 g) were selected and randomly divided into a control group, a 25 mg/L fluoride group, and a 50 mg/L fluoride group using a random number table method, with 10 rats in each group. The control group drank distilled water, while the fluoride exposure groups drank distilled water with fluoride ion concentrations of 25 and 50 mg/L, respectively. Five rats were euthanized in each group at 3 and 6 months of feeding, respectively. Visual observation was used to observe the occurrence of dental fluorosis in rats, and fluoride ion selective electrode method was used to detect the fluoride level in blood, urine, and cartilage. Hematoxylin-eosin staining and safranin O-fast green staining were used to observe the pathological changes of articular cartilage, and Mankin score was used to evaluate the grading of cartilage injury. Real-time fluorescence quantitative PCR was used to detect the expression levels of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage.Results:After 3 and 6 months of fluoride exposure, no dental fluorosis was observed in the control group, while rats in the 25 and 50 mg/L fluoride groups showed varying degrees of dental fluorosis. There were statistically significant differences in the levels of blood fluoride (mg/L: 0.11 ± 0.04, 0.57 ± 0.32, 0.29 ± 0.06, 0.07 ± 0.01, 0.31 ± 0.05, 0.38 ± 0.06), urine fluoride (mg/L: 1.81 ± 0.58, 13.18 ± 2.29, 66.11 ± 20.74, 2.35 ± 1.08, 14.79 ± 3.87, 28.32 ± 4.79), and cartilage fluoride (mg/kg: 341.83 ± 44.07, 612.99 ± 174.72, 991.26 ± 227.32, 338.29 ± 72.53, 957.09 ± 195.86, 1 535.53 ± 89.01) among in rats the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group ( F = 7.76, 42.78, 40.54, 23.10, 18.96, 80.81, P < 0.05). In the 50 mg/L fluoride group, there were statistically significant differences in the levels of urine fluoride and cartilage fluoride of rats exposed for different times ( t = 4.45, - 3.80, P < 0.05). The Mankin score grading for cartilage injury showed that at 3 months of fluoride exposure, there were 4, 0, and 0 rats with normal cartilage in the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group, 1, 4, and 1 rats with mild injury, and 0, 1, and 4 rats with moderate injury, respectively. At 6 months of fluoride exposure, there were 4, 0, and 0 rats with normal cartilage in the control group, 25 mg/L fluoride group, and 50 mg/L fluoride group, 1, 3, and 0 rats with mild injury, 0, 1, and 3 rats with moderate injury, and 0, 1, and 2 rats with severe injury, respectively. Real-time fluorescence quantitative PCR results showed that fluoride exposure dose had individual effects on the expression of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage ( F = 8.68, 7.97, 9.34, 10.14, P < 0.05). There was no individual effect of fluoride exposure time on the expression of miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p in cartilage ( F = 0.00, 0.15, 0.63, 0.53, P > 0.05). However, there was no interaction effect between fluoride exposure time and dose on the above-mentioned miRNA ( F = 0.68, 0.05, 0.22, 0.24, P > 0.05). The correlation analysis results showed that miR-675-3p and miR-675-5p in cartilage were negatively correlated with blood fluoride, urine fluoride, and cartilage fluoride ( r = - 0.37, - 0.42, - 0.56, - 0.53, - 0.57, - 0.53, P < 0.05), while miR-29b-3p and miR-let-7b-3p were positively correlated with urine fluoride and cartilage fluoride ( r = 0.58, 0.40, 0.48, 0.47, P < 0.05). The results of ordered logistic regression analysis showed that miR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p were influencing factors of dental fluorosis grading ( OR = 0.13, 0.04, 1.55, 2.58, P < 0.05) and Mankin score grading ( OR = 0.04, 0.06, 1.41, 1.58, P < 0.05). Conclusion:MiR-675-3p, miR-675-5p, miR-29b-3p, and miR-let-7b-3p may be involved in the process of fluoride induced articular cartilage injury.

Attention impairment in temporal lobe epilepsy (TLE) leads to other advanced cognitive impairments, such as memory and emotional recognition. Moreover, the severity of attention impairment determine the differences in strategies for preventing sudden unexpected death in epilepsy (SUDEP). Factors such as abnormal brain electrical discharges, sleep, and antiepileptic drugs are all associated with attention impairment. Neuroelectrophysiological observations have shown that abnormal electrical discharges interfere with the synchronization of cortical oscillations, and preventing the spread of abnormal epileptic discharges to subcortical activation structures helps reduce attention disorders. Neuroimaging reveals damage to the gray matter and white matter of the brain related to attention and poor connectivity of the whole-brain network. Therefore, early identification of attention impairment in TLE patients has become even more important. Treatment of attention impairment includes supplementing attention-related neurotransmitters, cognitive-behavioral therapy, surgical procedures, and neuromodulation techniques. This article mainly reviews the characteristics of attention impairment in TLE patients from the perspectives of clinical behavior, pathophysiology, and treatment, aiming to provide new insights for the early identification and management of attention impairment in TLE patients.

Objective:To investigate the hemodynamic characteristics of intracranial collateral circulation assessed non-invasively by TCD and their correlation with clinical prognosis in patients with severe carotid stenosis or occlusion.Methods:A retrospective cohort study design was used to include 96 patients with severe stenosis(≥70％)or occlusion of the unilateral internal carotid artery admitted from March 2021 to March 2024,who were divided into a well-compensated group(58 patients)versus a poorly-compensated group(38 patients)based on the ASITN/SIR collateral branch score.Hemodynamic parameters(PSV,EDV,MFV,PI,RI)were measured using TCD,and collateral circulation status was validated by digital subtraction angiography(DSA).Prognosis was evaluated over a 12-month follow-up.Logistic regression was used to analyze risk factors for poor prognosis.Results:The good collateral group exhibited significantly higher PSV(82.32±18.51 vs.56.45±15.32 cm/s)and MFV(56.93±12.33 vs.35.89±9.83 cm/s),and significantly lower PI(0.64±0.15 vs.0.82±0.21)and RI(0.43±0.08 vs.0.51±0.11)compared to the poor collateral group(all P＜0.001).TCD parameters showed strong correlations with ASITN/SIR grades(PSV:r=0.62;PI:r=-0.61,all P＜0.001).Multivariate analysis identified age ≥65 years(OR=1.06),hypertension(OR=3.07),PI ≥ 1.00(OR=17.25),and PSV ≤ 60 cm/s(OR=1.96)as independent risk factors for poor prognosis(all P＜0.05).Conclusion:The TCD multi-parameter model enables quantitative assessment of collateral circulation function,with PI ≥ 1.00 and PSV ≤ 60 cm/s serving as key predictors of adverse outcomes.The non-invasive and dynamic monitoring advantages of TCD provide critical insights for hemodynamic stratification and personalized intervention in patients with carotid stenosis or occlusion.

OBJECTIVE To explore the intervention mechanism of Shangke Lengtongtie on cold hyperalgesia in KOA mice based on the HMGB1/CXCL12/CXCR4 signaling axis.METHODS Monosodium iodoacetate(MIA)was used for the intra-articular injec-tion into the knee joint to establish mice model of knee osteoarthritis(KOA).Peripheral blood monocytes were extracted from mice,cultured,and then reinfused into the tail vein of the mice.Subsequently,in vivo animal imaging was used to observe the recruitment sites of these monocytes.The cold hyperalgesia threshold was measured at various time points in each group of mice.Hematoxylin and eosin(HE)staining was used to evaluate the level of synovial pathological changes.ELISA was employed to detect the expression of in-flammatory factors IL-1β,TNF-α,and pain mediators CGRP and Substance P in mouse serum.Western blot and qPCR methods were used to detect the protein and gene expression of cold hyperalgesia-related indicators such as TRPA1,TRPM8,HMGB1,CXCL12,CXCR4,Collagen Ⅰ,and Netrin-1 in synovial tissue,as well as DCC in dorsal root ganglia(DRG)tissue.RESULTS In vivo ima-ging showed that after the monocytes were reinfused into KOA mice,they were recruited to the knee joint area,with the HMGB1 group exhibiting a greater recruitment of circulating monocytes at the knee joint.Additionally,compared to the control group,the KOA group and HMGB1 group showed inflammatory pathological changes in the synovium,increased expression of serum inflammatory factors and pain mediators,reduced cold hyperalgesia threshold,and upregulated protein and gene expression of cold hyperalgesia-related indica-tors in synovial and DRG tissues.The changes were more significant in the HMGB1 group compared to the KOA group(P<0.05).Af-ter treatment with Shangke Lengtongtie or GL intervention,synovial inflammation was alleviated,serum inflammatory factors and pain mediators decreased,cold hyperalgesia threshold increased,and the upregulation of cold hyperalgesia-related indicator protein and gene expression levels was significantly reversed(P<0.05).CONCLUSION Shangke Lengtongtie exerts a beneficial effect on the mitigation of synovitis and cold hyperalgesia in KOA mice,a therapeutic mechanism that possibly mediated through the inhibition of the HMGB1/CXCL12/CXCR4 signaling axis.
