ObjectiveTo screen for and validate key differentially expressed proteins in serum of patients with metabolic dysfunction‑associated fatty liver disease （MAFLD）， and to provide a basis for identifying diagnostic biomarkers and developing intervention strategies for this disease. MethodsA total of 20 patients who were diagnosed with MAFLD in the third affiliated hospital of Chengdu University of Traditional Chinese Medicine from December 2024 to January 2025 were enrolled as MAFLD group， and 20 healthy controls were enrolled as HC group. Demographic data and serum biochemical parameters were collected from both groups. Data-independent acquisition （DIA） quantitative proteomics was used to measure the relative expression levels of serum proteins， and related methods were used to obtain significantly differentially expressed proteins， including the gene ontology functional enrichment analysis， the Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis， protein-protein interaction （PPI） network， Hub node interaction， and weighted gene co-expression network analysis （WGCNA）. Rats were given a high-fat diet to establish a model of MAFLD， and randomly assigned to the control group and model group. Serum biochemical parameters and inflammatory factors were measured， liver histopathological changes were observed， and the protein expression levels of MER proto-oncogene tyrosine kinase （MERTK） and matrix metalloproteinase-9 （MMP-9） in liver tissue were verified. The independent-samples t test was used for comparison of normally distributed continuous data between groups， while the Mann-Whitney U test was used for comparison of non-normally distributed continuous data or data with heterogeneity of variance between groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsCompared with the HC group， the MAFLD group had significant increases in the serum levels of aspartate aminotransferase （t=-7.348， P<0.05）， alanine aminotransferase （Z=5.088， P<0.05）， alkaline phosphatase （t=-3.943， P<0.05）， triglyceride （Z=2.070， P<0.05）， and high-density lipoprotein cholesterol （t=3.867， P<0.05）. A total of 3 559 proteins were identified by DIA serum proteomics， among which 160 differentially expressed proteins were mainly enriched in pathways including metabolic disorders， immune inflammatory response， and extracellular matrix remodeling. The PPI network and the Hub node analysis showed that serpin family E member 1， MMP-9， and intercellular cell adhesion molecule-1 were core regulatory proteins. WGCNA showed that the MEyellow module was significantly positively correlated with MAFLD phenotype （cor=0.55， P<0.001）， which was functionally enriched in the efferocytosis pathway. MERTK （P<0.001） and MMP-9 （P<0.001） showed the most significant differential expression in this module. A rat model of MAFLD was successfully established using a high-fat diet， and compared with the control group， the model group had enlarged， yellowish， and greasy liver and disordered structure of hepatic lobules， hepatocyte fatty degeneration， and inflammatory cell infiltration based on HE staining， as well as massive lipid droplet deposition based on oil red O staining， while no obvious fibrous cords were observed in Masson staining. Compared with the control group， the model group had significant increases in the serum levels of aspartate aminotransferase （t=-5.148， P<0.05）， alanine aminotransferase （t=-5.663， P<0.05）， total bilirubin （t=-13.061， P<0.05）， triglyceride （Z=-2.722， P<0.05）， total cholesterol （t=3.588， P<0.05）， and tumor necrosis factor-α （t=-16.741， P<0.05）， as well as significant increases in the protein expression levels of MERTK （t=-11.448， P<0.001） and MMP-9 （t=-10.875， P<0.001） in liver tissue. ConclusionMMP-9 and MERTK are abnormally expressed in MAFLD and may be used as potential diagnostic biomarkers for this disease.

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.

Objective:To explore the longitudinal predictive relationship between self-neglect and frailty among older adults.Methods:Data were drawn from the Chinese Longitudinal Healthy Longevity Survey conducted in 2011 (T1), 2014 (T2), and 2018 (T3). A total of 1 495 older adults aged≥65 years at T1 who participated in three consecutive surveys and had no missing key variables were included. General demographic information, self-neglect scores, and frailty status were extracted. Spearman correlation analysis was used to examine the association between self-neglect and frailty. Cross-lagged analysis was employed to investigate the potential causal relationship between the two variables.Results:The self-neglect scores for 1 495 older adults at T1, T2, and T3 were (2.84±1.39), (2.47±1.30), and (2.41±1.20), respectively, showing a declining trend. The frailty scores at T1, T2, and T3 were 0 (0, 1.00), 0 (0, 2.00), and 1.00 (0, 2.00), respectively, indicating an increasing trend. Cross-lagged analysis revealed that self-neglect at T1 positively predicted frailty at T2 (β=0.076, P=0.004). Frailty at both T1 and T2 positively predicted self-neglect at T2 (β=0.057, P=0.044) and T3 (β=0.058, P=0.029), respectively. Conclusions:Frailty among older adults positively predicts self-neglect, and self-neglect also has a certain predictive effect on frailty. Medical staff should strengthen early screening and intervention for frailty in older adults to delay the occurrence and progression of self-neglect.

Objective:To compare the efficacy and safety of two induction regimens, homoharringtonine plus venetoclax and azacitidine (VHA) versus venetoclax and azacitidine (VA) , for newly diagnosed acute myeloid leukemia (AML) patients who are elderly or ineligible for intensive chemotherapy.Methods:We retrospectively analyzed the clinical data of 59 newly diagnosed AML patients treated with the VHA or VA regimen at Zhengzhou University Affiliated Cancer Hospital from September 2018 to July 2021. The cohort included 25 males and 34 females, with a median age of 63 years. The overall response rate (ORR) , composite complete remission (CRc) rate [CR+CR with incomplete hematologic recovery (CRi) ], minimal residual disease (MRD) negativity rate, overall survival (OS) , relapse-free survival (RFS) , and adverse events were compared between the two groups. Survival was estimated by the Kaplan-Meier method, and prognostic factors were evaluated using univariable and multivariable Cox regression.Results:At the end of the treatment, the ORR was 88.4% (23/26) in the VHA group [21 CR, 2 partial remissions (PR) ] and 90.9% (30/33) in the VA group (25 CR, 5 PR) , with no significant difference between the groups ( P=0.458) . The MRD negativity rates after one cycle of induction were 73.1% (19/26) in the VHA group and 60.6% (20/33) in the VA group, respectively ( P=0.315) . In the high-risk subgroup, the composite remission rates after one cycle were 78.6% (11/14) with VHA and 50.0% (5/10) with VA ( P=0.143) ; MRD negativity rates were 64.3% (9/14) and 20.0% (2/10) , respectively ( P=0.032) . The main adverse events were myelosuppression, gastrointestinal reactions, and infections during neutropenia. Rates of grade 3-4 neutropenia and decreased hemoglobin were similar between groups, whereas grade 3-4 thrombocytopenia was more frequent with VHA than with VA (76.9% vs 45.5%, P=0.015) . With a median follow-up of 13 months (range, 1-59) , 1 year RFS was 69.9% (95% CI: 53.1%-92.2%) with VHA and 55.6% (95% CI: 40.1%-77.1%) with VA ( P=0.305) . The 1 year OS rates were 91.7% (95% CI: 77.3%-100.0%) and 58.2% (95% CI: 41.7%-81.4%) , respectively ( P=0.024) . Among high risk patients, 1 year RFS and OS were higher with VHA than with VA (RFS: 66.2% vs 37.5%, P=0.046; OS: 85.7% vs 48.0%, P=0.011) . Undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) significantly improved RFS and OS ( P=0.027 and 0.047, respectively) . On multivariable analysis, ELN risk classification and MRD negativity after the first cycle were independent prognostic factors for RFS. Treatment regimen (VHA vs VA) , MRD negativity after the first cycle, and receipt of transplantation were independent prognostic factors for OS. Conclusion:VHA provides clinical benefit in newly diagnosed AML patients who are unfit for intensive chemotherapy and in older adults, with particularly favorable outcomes in high risk patients; sequential allo-HSCT confers additional benefit, and associated adverse events are manageable.

This study sought to evaluate the efficacy and safety of venetoclax (Ven) in combination with tyrosine kinase inhibitors (TKI) and reduced-dose chemotherapy for the treatment of patients with minimal residual disease (MRD) -positive and relapsed/refractory (R/R) Ph-positive acute lymphoblastic leukemia (Ph + ALL). A retrospective analysis was conducted on the clinical data of 13 patients with MRD-positive and relapsed Ph + ALL admitted between July 2015 and February 2024 at the Affiliated Cancer Hospital of Zhengzhou University. The cohort included seven males and six females, with a median age of 50 years (range: 37-71 years). Reinduction therapy consisted of Ven and TKI administration combined with reduced-dose chemotherapy. Among the 13 patients, 10 were MRD-positive, and three had R/R disease. Of the MRD-positive group, nine (90%) achieved complete molecular response (CMR), with a median time to response of 47 days (range: 30-80) ; one patient did not respond. Among the three patients who had R/R, two (66.6%) achieved complete remission, while one patient was nonresponsive. The median overall survival (OS) and relapse-free survival (RFS) time for the entire cohort were 21.5 months and 7 months, respectively. In patients who achieved CMR, the median OS and RFS time were 35 months and 34 months, respectively. Grade ≥3 hematologic adverse events occurred in five patients (38.4%) ; however, hematopoietic function recovered in all cases, and no grade ≥3 infections or organ-related adverse reactions were observed. These findings suggest that Ven combined with TKI and reduced-dose chemotherapy may be an effective and tolerable therapeutic strategy for MRD-positive and R/R Ph + ALL, particularly in significantly improving MRD clearance rates.

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.
