Objective To observe the change of learning and memory and the expression change of GABAR1 and N-methyl-D-aspartate receptor 2B (NMDAR2B)in right frontal lobe of the brain of the aged rats after the inhalation of sevoflurane.Methods Fifty male SD rats were randomly divided into control group (group C,n=10)and experimental group (group T,n=40).The control group received air at room tempreture.Experimental groups were divided into two groups:group T1 (2 h)and group T2 (4 h)according to the time of inhalation of sevoflurane at 3% concentration.Ev-ery group was equally divided into two groups and Morris water maze was performed on day 1 and day 7 after sevoflurane inhalation.Then the right frontal lobe was gathered and the mRNA transcription and protein expression of GABAR1 and NMDAR2B were detected by Quantitative Real-time PCR and immunofluorescence technique.Results Compared with group C,the escape latency was prolonged in groups T1 and T2 after 1 day of inhalation of sevoflurane (P<0.05),and the times of space explora-tion reduced (P<0.05).mRNA transcriptional and protein content of GABAR1 were significantly upregulated in frontal lobes of groups T1 and T2,mRNA transcriptional and protein content of NMDAR2B were significantly down-regulated (P<0.05).After inhalation of sevoflurane for 7 days, the protein expression of NMDAR2B in the frontal lobe of group T1 was lower than that of group C (P<0.05).In group T2,the escape latency was prolonged (P<0.05),the number of space explo-ration traversals was decreased (P<0.05),the expression of GABAR1 protein in frontal lobe was up-regulated (P<0.05),and the expression of NMDAR2B protein was down-regulated (P<0.05), and the amplitude was higher than that in group T1 (P<0.05).Conclusion Continuous inhalation of sevoflurane can reduce the spatial memory ability of aged rats,and the effect of prolonged inhalation is greater and longer.This effect is related to the expression of neurotransmitter receptors such as GABAR1 and NMDAR2B in the frontal lobe.

Objective To investigate the clinical diagnostic value of extra-spindle pole-like protein 1(ESPL1)in the progression of hepatitis B virus(HBV)-related liver fibrosis.Methods A total of 228 patients with HBV infection who were admitted to The First Affiliated Hospital of Guangxi Medical University from June 2017 to August 2023 were enrolled.The transient elastography system FibroScan was used to determine liver stiffness measurement(LSM)for all patients,and according to the LSM value,they were divided into non-liver fibrosis group with 80 patients,mild liver fibrosis group with 83 patients,advanced liver fibrosis group with 30 patients,and liver cirrhosis group with 35 patients.ELISA was used to measure the serum level of ESPL1.The Kruskal-Wallis H test was used for comparison of the serum level of ESPL1 between the four groups;the Spearman correlation analysis was used to investigate the correlation between ESPL1 and LSM;the receiver operating characteristic(ROC)curve was used to analyze the value of serum ESPL1 in predicting the progression of liver fibrosis.Results The liver cirrhosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group and the mild liver fibrosis group(both P<0.05),and the advanced liver fibrosis group and the mild liver fibrosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group(both P<0.05).The correlation analysis showed that there was a positive correlation between serum ESPL1 and LSM in the patients with HBV infection and varying degrees of liver fibrosis(r=0.515,P<0.001).Serum ESPL1 had an area under the ROC curve(AUC)of 0.809 in predicting liver cirrhosis and an AUC of 0.638 in predicting advanced liver fibrosis,with a sensitivity of 87.5%and 100%,respectively,and a specificity of 59.7%and 31.3%,respectively.Conclusion There is a certain correlation between serum ESPL1 and HBV-related liver fibrosis,and higher serum ESPL1 may indicate a higher degree of liver fibrosis.Serum ESPL1 is expected to become one of the serum markers for assisting in the diagnosis of liver cirrhosis and an important clinical method for dynamically monitoring the progression of liver fibrosis in patients with HBV infection.

Vegetable and fruit allergies are common types of food allergies worldwide, most of them are triggered by primary sensitization to pollen. Most allergens in vegetables and fruits belong to a few cross-reactive proteins such as PR-10 proteins, profilins, and nsLTPs. The presence of these allergens in various plants can lead to widespread cross-reactive allergic responses. Component-resolved diagnostics (CRD) can improve diagnostic accuracy by precisely identifying specific allergenic proteins, aiding physicians in making more accurate treatment and management decisions, and reducing unnecessary food avoidance. This article, based on the "Molecular Allergology User′s Guide 2.0 (MAUG 2.0)" issued by the European Academy of Allergy and Clinical Immunology (EAACI), analyzes the primary mechanisms, relevant allergens, and diagnostic and clinical management strategies for vegetable and fruit allergies. By detailing and analyzing these allergenic components, this article may help the healthcare professionals to deep the understandings of vegetable and fruit allergies, offer new perspectives and practical guideline for the research and treatment of these allergies, and promot the development of precise diagnostics and personalized treatment strategies.

Wheat and buckwheat allergies are common food allergies that significantly impact patients′ quality of life and health. Wheat allergy encompasses various forms, including wheat food allergy, exercise-induced allergic reactions (WDEIA), baker′s occupational asthma/allergy, and contact urticaria. IgE-mediated allergic reactions involve sensitization to stable wheat allergens such as ω-5 gliadin and gluten. Although buckwheat allergy is less common, it is gaining attention in certain regions. Allergen component diagnostic technologies, by detecting specific allergen components [e.g., ω-5 gliadin, gliadins (α, β, γ), and Tri a 14], offer precise allergen source identification, aiding in the optimization of diagnosis and management processes. Oral challenge tests are considered the gold standard for diagnosing wheat allergy, and combining skin prick tests with specific IgE measurements can enhance diagnostic accuracy. While avoidance of allergens remains the primary management strategy, research into immunotherapy is ongoing. Future research should focus on a deeper understanding of the structural and immunological characteristics of wheat and buckwheat allergens to develop more accurate diagnostic tools and treatment methods, thereby improving allergy management and patient quality of life. This article provides a detailed interpretation of the Molecular Allergology User′s Guide 2.0 (MAUG 2.0) published by the European Academy of Allergy and Clinical Immunology (EAACI) and recent research advances on wheat and buckwheat allergies, highlighting the crucial role of allergen component diagnostics in optimizing food allergy diagnosis and treatment processes, supporting clinicians in accurately identifying common allergens and their cross-reactivity, and formulating more personalized treatment plans for patients.
