BackgroundAnxiety disorder is a common mental disorder, with its prevalence showing a continuous upward trend, significantly affecting the quality of life and social function of patients. Due to the lack of objective and reliable biomarkers in clinical practice, the early identification and treatment of anxiety disorder have been somewhat limited. Plasma proteins have the potential to serve as biomarkers for mental diseases, however, the causal relationship between them and anxiety disorder remains unclear. ObjectiveTo identify the plasma proteins that have a causal relationship with anxiety disorders, and to elucidate the associated biological pathways, in order to provide references for the search for biomarkers of anxiety disorders and the exploration of potential therapeutic targets. MethodsBased on the protein quantitative trait locus (pQTL) data of 4 907 plasma proteins covering 35 559 Icelandic individuals from the deCODE database, and the genome-wide association studies (GWAS) data of 50 486 patients with anxiety disorders and 330 460 healthy controls, the inverse-variance weighted (IVW) method was used as the main analysis method, supplemented by MR-Egger method, weighted median method, simple model method, and weighted model method for bidirectional Mendelian randomization analysis. Enrichment analysis of gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways was conducted for the related proteins. Sensitivity analysis was performed using Cochran's Q test, MR-Egger intercept test, MR-PRESSO test, and leave-one-out analysis to evaluate the robustness of the results. ResultsA total of 10 plasma proteins were identified as significantly associated with anxiety disorders. Among these, SPATA9 (OR=0.856, 95% CI: 0.784–0.934, P<0.01) and PDE5A (OR=0.911, 95% CI: 0.864–0.961, P<0.01) were identified as protective factors, while CRYGD (OR=1.209, 95% CI: 1.095–1.334, P<0.01), BTN3A3 (OR=1.045, 95% CI: 1.018–1.073, P<0.01), SERPINB13 (OR=1.102, 95% CI: 1.040–1.168, P<0.01), ERBB4 (OR=1.283, 95% CI: 1.109–1.484, P<0.01), LSAMP (OR=1.096, 95% CI: 1.037–1.158, P<0.01), ICOSLG (OR=1.283, 95% CI: 1.104–1.490, P<0.01), DNAJB11 (OR=1.172, 95% CI: 1.076–1.277, P<0.01), and TREML1 (OR=1.115, 95% CI: 1.054–1.179, P<0.01) were identified as risk factors. The sensitivity analysis showed that the results were robust, with no heterogeneity (Cochran's Q test P>0.05) or pleiotropy (MR-Egger intercept test P>0.05). Enrichment analysis indicated that these plasma proteins were enriched in biological processes such as T-cell signal transduction, lymphocyte proliferation, cell membrane structure and synaptic function, as well as the intestinal immune network that produces IgA and the ErbB signaling pathway. ConclusionThis study identified 10 plasma proteins associated with anxiety disorders. The functions of these plasma proteins involve multiple biological processes such as neural development and immune regulation.

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics. There is an urgent need for a precise and adaptable restoration strategy that is more suitable for older individuals. The proposal of a new concept of functional tooth loss updates the minimal restoration standards for elderly patients and establishes the theory of age-friendly functional restoration. Based on the restoration strategy of functional tooth loss, this paper proposes a new concept termed "age-friendly functional restoration of the stomatognathic system", which integrates treatment considerations including endodontics, periodontology, mucosa, muscles, temporomandibular joint, and systemic health. Efforts should be made in four areas as follows. Firstly, the "assessment of accessible function" should be enhanced by considering the interrelationship between stomatognathic and systemic health. Secondly, the "evaluation of appropriate function" is supposed to be optimised in view of subjective needs and objective evaluation of the stomatognathic system. Moreover, the "formulation of treatment plans" needs to be accomplished with the aid of assistive technologies, such as artificial intelligence, to accurately exert appropriate functional restoration. Lastly, the "management and maintenance of health" is likely to be strengthened through follow-ups, propaganda and education, and preventive healthcare, so as to improve quality of life and ultimately achieve healthy ageing among older individuals.

Objective To investigate the establishment and evaluation method of a rat model for cold asthma syndrome during the acute exacerbation phase of asthma.Methods Thirty-two rats were randomly allocated into four distinct groups:normal control group,asthma group,cold asthma group,and Shegan Mahuang Decoction group(SMD).While the normal control group was not subjected to any modeling procedures,the remaining groups were induced to develop asthma by a combination of intraperitoneal injections and atomized inhalation of ovalbumin sensitization solution.Furthermore,to emulate the traditional Chinese medicine syndrome of cold asthma,the cold asthma group and the SMD underwent an additional protocol involving"swimming,cold water consumption,and external cold stimulation."Commencing from the 14th day of the experiment,the SMD received daily gavage administration of Shegan Mahuang Decoction for a consecutive period of 14 days.The cold asthma rat model was comprehensively evaluated from both macroscopic and microscopic perspectives.Results ①Following model induction,both the asthma and cold asthma groups exhibited significant increases in asthmatic behavioral scores,sluggish weight gain,and airway hyperreactivity.Additionally,there was a notable rise in eosinophils(EOS)in the bronchoalveolar lavage fluid(BALF),decreased expression of aquaporin-5(AQP5)in lung tissue,and altered immune balances with reduced Th1/Th2 ratios and elevated Th17/Treg ratios in the spleen.Hemorheological changes included increased whole blood viscosity,relative high-shear,and low-shear indices,alongside a marked decline in erythrocyte aggregation index.The cold asthma group further displayed pronounced cold asthma symptoms,slower weight gain,and more significant increases in whole blood viscosity and low-shear relative index compared to the asthma group.②Administration of SMD alleviated asthmatic behaviors and traditional Chinese medicine syndrome manifestations in cold asthma rats,resulting in enhanced weight gain.SMD also mitigated airway hyperreactivity,reduced EOS percentage in BALF,and ameliorated lung tissue damage and inflammatory cell infiltration.The treatment increased AQP5 expression levels and rectified the immune imbalances of Th1/Th2 and Th17/Treg in cold asthma rats.Furthermore,SMD significantly lowered whole blood viscosity,relative high-shear,and low-shear indices in these rats.Conclusion The research effectively established a model for cold asthma syndrome in TCM through a method that integrates intraperitoneal injection,nebulized ovalbumin sensitization,and a triad of swimming,cold water intake,and external cold exposure.This model consistently displays the symptoms of cold asthma and corresponds with the microscopic pathological alterations seen in asthma,thereby validating the robustness of the model's creation process.

Objective To analyze the clinical and immunological characteristics of a rare case of CHARGE syndrome,we summarize the genotype and phenotype in the Chinese patient population,and explore the underlying immunopathogenic mechanisms.Methods Clinical data from a pediatric patient with CHARGE syndrome were collected and analyzed.A comprehensive analysis of the Chinese patient population was conducted.Gene analysis and immunological characterization were performed using flow cytometry,deep sequencing,and quantitative PCR.Results The proband was a premature female infant whose primary clinical manifestations included congenital heart disease,recurrent respiratory infections,respiratory failure,airway dysplasia,hearing impairment,and bilateral choroidal coloboma.Whole-exome sequencing revealed a de novo heterozygous nonsense mutation in the CHD7 gene,c.5122C>T(p.Gln1708Ter),classified as pathogenic according to ACMG criteria.Immunological studies indicated impaired thymic output of T cells,significant alterations in the number and proportion of CD8+T cell subsets,increased apoptosis,and defective activation and production of key effector cytokines such as IFN-γ by CD8+T cells.However,no significant abnormalities were observed in peripheral lymphocyte proliferation.Conclusion CHARGE syndrome is a rare autosomal dominant genetic disorder primarily caused by mutations in the CHD7 gene.The main clinical features include ocular defects,cardiac disease,choanal atresia/cleft lip and palate,growth retardation,gonadal hypoplasia,and ear anomalies.This case study suggests that CHARGE syndrome is associated with abnormalities in the development,apoptosis,and effector functions of immune cells.

This study investigated the effects and underlying mechanisms of vanillic acid(VA) against cardiac fibrosis(CF) induced by isoproterenol(ISO) in mice. Male C57BL/6J mice were randomly divided into control group, VA group(100 mg·kg~(-1), ig), ISO group(10 mg·kg~(-1), sc), ISO + VA group(10 mg·kg~(-1), sc + 100 mg·kg~(-1), ig), ISO + dynamin-related protein 1(Drp1) inhibitor(Mdivi-1) group(10 mg·kg~(-1), sc + 50 mg·kg~(-1), ip), and ISO + VA + Mdivi-1 group(10 mg·kg~(-1), sc + 100 mg·kg~(-1), ig + 50 mg·kg~(-1), ip). The treatment groups received the corresponding medications once daily for 14 consecutive days. On the day after the last administration, cardiac functions were evaluated, and serum and cardiac tissue samples were collected. These samples were analyzed for serum aspartate aminotransferase(AST), lactate dehydrogenase(LDH), creatine kinase-MB(CK-MB), cardiac troponin I(cTnI), reactive oxygen species(ROS), interleukin(IL)-1β, IL-4, IL-6, IL-10, IL-18, and tumor necrosis factor-α(TNF-α) levels, as well as cardiac tissue catalase(CAT), glutathione(GSH), malondialdehyde(MDA), myeloperoxidase(MPO), superoxide dismutase(SOD), total antioxidant capacity(T-AOC) activities, and cytochrome C levels in mitochondria and cytoplasm. Hematoxylin-eosin, Masson, uranium acetate and lead citrate staining were used to observe morphological and mitochondrial ultrastructural changes in the cardiac tissues, and myocardial injury area and collagen volume fraction were calculated. Flow cytometry was applied to detect the relative content and M1/M2 polarization of cardiac macrophages. The mRNA expression levels of macrophage polarization markers [CD86, CD206, arginase 1(Arg-1), inducible nitric oxide synthase(iNOS)], CF markers [type Ⅰ collagen(Coll Ⅰ), Coll Ⅲ, α-smooth muscle actin(α-SMA)], and cytokines(IL-1β, IL-4, IL-6, IL-10, IL-18, TNF-α) in cardiac tissues were determined by quantitative real-time PCR. Western blot was used to detect the protein expression levels of Coll Ⅰ, Coll Ⅲ, α-SMA, Drp1, p-Drp1, voltage-dependent anion channel(VDAC), hexokinase 1(HK1), NOD-like receptor protein 3(NLRP3), apoptosis-associated speck-like protein(ASC), caspase-1, cleaved-caspase-1, gasdermin D(GSDMD), cleaved N-terminal gasdermin D(GSDMD-N), IL-1β, IL-18, B-cell lymphoma-2(Bcl-2), B-cell lymphoma-xl(Bcl-xl), Bcl-2-associated death promoter(Bad), Bcl-2-associated X protein(Bax), apoptotic protease activating factor-1(Apaf-1), pro-caspase-3, cleaved-caspase-3, pro-caspase-9, cleaved-caspase-9, poly(ADP-ribose) polymerase-1(PARP-1), and cleaved-PARP-1 in cardiac tissues. The results showed that VA significantly improved cardiac function in mice with CF, reduced myocardial injury area and cardiac index, and decreased serum levels of AST, CK-MB, cTnI, LDH, ROS, IL-1β, IL-6, IL-18, and TNF-α. VA also lowered MDA and MPO levels, mRNA expressions of IL-1β, IL-6, IL-18, and TNF-α, and mRNA and protein expressions of Coll Ⅰ, Coll Ⅲ, and α-SMA in cardiac tissues, and increased serum levels of IL-4 and IL-10, cardiac tissue levels of CAT, GSH, SOD, and T-AOC, and mRNA expressions of IL-4 and IL-10. Additionally, VA ameliorated cardiac pathological damage, inhibited myocardial cell apoptosis, inflammatory infiltration, and collagen fiber deposition, reduced collagen volume fraction, and alleviated mitochondrial damage. VA decreased the ratio of F4/80~+CD86~+ M1 cells and the mRNA expressions of CD86 and iNOS in cardiac tissue, and increased the ratio of F4/80~+CD206~+ M2 cells and the mRNA expressions of CD206 and Arg-1. VA also reduced protein expressions of p-Drp1, VDAC, NLRP3, ASC, caspase-1, cleaved-caspase-1, GSDMD, GSDMD-N, IL-1β, IL-18, Bad, Bax, Apaf-1, cleaved-caspase-3, cleaved-caspase-9, cleaved-PARP-1, and cytoplasmic cytochrome C, and increased the expressions of HK1, Bcl-2, Bcl-xl, pro-caspase-3, pro-caspase-9 proteins, as well as the Bcl-2/Bax and Bcl-xl/Bad ratios and mitochondrial cytochrome C content. These results indicate that VA has a significant ameliorative effect on ISO-induced CF in mice, alleviates ISO-induced oxidative damage and inflammatory response, and its mechanism may be closely related to the inhibition of Drp1/HK1/NLRP3 and mitochondrial apoptosis signaling pathways, suppression of myocardial cell inflammatory infiltration and collagen fiber deposition, reduction of collagen volume fraction and CollⅠ, Coll Ⅲ, and α-SMA expressions, thus mitigating CF.
