OBJECTIVE To investigate the therapeutic effect and mechanism of Qiwei dongqingye powder （QDP） on bronchial asthma in mice. METHODS The mice were divided into blank group （normal saline）， model group （normal saline）， dexamethasone group （2 mg/kg）， and QDP low-， medium-， and high-dose groups （200， 400， 800 mg/kg）， with 14 mice in each group. Except for the blank group， mice in all other groups were given ovalbumin via intraperitoneal injection followed by aerosol inhalation to induce a bronchial asthma model. During the modeling process， mice in each group were administered corresponding drug solutions or normal saline intragastrically/intraperitoneally. After the last medication， the number of cells in the bronchoalveolar lavage fluid （BALF） of the mice was observed and counted； the pathological changes of the bronchus and lung tissue were observed； the levels of malondialdehyde （MDA）， nitric oxide （NO）， total superoxide dismutase （T-SOD）， and glutathione peroxidase （GSH-Px） in the lung tissue of the mice were determined， and the level of interleukin-17 （IL-17） in the BALF and serum was determined. Transcriptomics was employed to predict and validate the mechanism of action of QDP against bronchial asthma. RESULTS Compared with the model group， the total cell count， neutrophil count， lymphocyte count， and macrophage counts in the BALF of the QDP high-dose group were all significantly reduced （ P ＜0.05）； the levels of MDA and NO in the lung tissue， and the levels of IL-17 in the BALF and serum were all decreased significantly （ P ＜0.05）； the levels of T-SOD and GSH-Px were significantly increased （ P ＜0.05）； the arrangement of lung tissue cells tended to normalize， with reduced infiltration of inflammatory cells and decreased exfoliation of bronchial simple columnar epithelial cells. The transcriptomic results revealed that the differentially expressed genes were B-cell receptor signaling pathway， nuclear factor κB （NF-κB） signaling pathway， ferroptosis signaling pathway， and others. Further validation revealed that， compared with the model group， the expression levels of NF-κB p65 and chemokine ligand 20， as well as the phosphorylation level of NF-κB inhibitor protein α， were significantly decreased in the lung tissues of the mice in all QDP groups （ P ＜0.05）. Conversely， the protein expression of nuclear factor erythroid 2-related factor 2 （Nrf2） and heme oxygenase 1 （HO-1） were significantly increased （ P ＜0.05）. CONCLUSIONS QDP can effectively alleviate bronchial asthma by inhibiting the NF-κB signaling pathway， activating the Nrf2/HO-1 signaling pathway， regulating oxidative stress， and reducing inflammatory responses.

ObjectiveThis paper aims to explore the in vitro anti-psoriasis activity and potential mechanism of Kangfuxin liquid （KFX liquid）， providing experimental evidence for the anti-psoriasis effect of KFX liquid. MethodsFirstly， the uninduced human immortalized keratinocyte cells （HaCaT cells） were divided into seven groups， namely the control group and KFX liquid groups with different doses （5， 10， 20， 40， 80， 160 g·L^-1）. After being treated with different concentrations of KFX liquid， the effect of KFX liquid on the normal cell proliferation was detected by using the cell counting kit-8 （CCK-8） method. Secondly， the uninduced HaCaT cells were divided into six groups， namely the control group and recombinant human interleukin-7A （rh-IL-7A） groups with different doses （5， 10， 50， 100， 120 g·L^-1）. After being treated with different concentrations of recombinant human interleukin-17A （rh IL-17A） liquid， the effect of rh IL-17A on cell proliferation was detected. The optimal induction concentration was screened. Then， normal HaCaT cells were divided into a control group and KFX liquid groups with different doses （5， 10， 20， 40， 80， 160 g·L^-1）. Except for the control group， the other groups established psoriasis cell models with the optimal induction concentration of rh IL-17A. After being treated with different concentrations of KFX liquid， the effects of KFX liquid on the psoriasis-like HaCaT cell proliferation were investigated. Finally， the uninduced HaCaT cells were divided into six groups， namely the control group， rh IL-17A group， methotrexate （MTX） group， and KFX liquid groups with different doses （20， 40， 80 g·L^-1）. Except for the control group， the other groups used the optimal induction concentration of rh IL-17A to establish psoriasis cell models. After being treated with different drugs， the cell migration levels were detected through scratch assays， and real-time quantitative polymerase chain reaction （Real-time PCR） was used to detect the relative mRNA expression levels of Ki-67 antigen （Ki67）， S100 calcium-binding protein A7 （S100A7）， S100 calcium-binding protein A8 （S100A8）， and S100 calcium-binding protein A9 （S100A9）， thereby comprehensively evaluating the in vitro anti-psoriasis activity of KFX liquid. By detecting the relative mRNA expression levels of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and chemokine-20 （CXCL-20） inflammatory-related factors in psoriasis-like HaCaT cells and the protein expression levels of Janus kinase 3 （JAK3）， phosphorylated Janus kinase 3 （p-JAK3）， signal transducer and activator of transcription 3 （STAT3）， and phosphorylated signal transducer and activator of transcription 3 （p-STAT3）， the mechanism was explored. ResultsCompared with that of control group， when treated with 80 g·L^-1 KFX liquid for 72 h （P<0.05） and at different times with 160 g·L^-1 KFX liquid， the HaCaT cell proliferation activity was significantly affected （P<0.01）， while the other concentrations of KFX liquid had no significant differences in cell morphology and cell proliferation activity at different times， indicating that the KFX liquid is relatively safe for HaCaT cells and has no obvious toxic side effects. Compared with that of control group， when treated with different concentrations of rh IL-17A for 24 h， the HaCaT cell proliferation activity was significantly enhanced， and the cell activity was the strongest when the concentration was 100 μg·L^-1 （P<0.05）， with a density close to 100% and intact cell morphology， indicating that 100 μg·L^-1 is the optimal concentration for inducing HaCaT cell proliferation. The results of the KFX liquid treatment on rh IL-17A-induced psoriasis-like cells show that the KFX liquid not only effectively inhibits the rh IL-17A-induced psoriasis-like HaCaT cell proliferation activity （P<0.01）， but also significantly reduces the migration ability of rh IL-17A-induced psoriasis-like HaCaT cells （P<0.01）， and the relative mRNA expression levels of Ki67， S100A7， S100A8， and S100A9 （P<0.01）. Moreover， the KFX liquid can significantly reduce the relative mRNA expression levels of IL-1β， IL-6， and CXCL-20 in rh IL-17A-induced psoriasis-like cells （P<0.01）， and significantly inhibit the phosphorylation levels of JAK3 and STAT3 proteins （P<0.05， P<0.01）. ConclusionThe KFX liquid has no obvious toxicity to uninduced HaCaT cells. It can inhibit rh IL-17A-induced psoriasis-like HaCaT cell proliferation， reduce the cell migration ability， and has good in vitro anti-psoriasis activity. Its action mechanism may be related to downregulating the expression levels of inflammation-related cytokines in the JAK3/STAT3 signaling pathway and inhibiting the phosphorylation levels of JAK3 and STAT3 proteins.

Objective To study the correlation of cognitive dysfunction with autonomic nerve function damage in patients with cerebral small vessel disease (CSVD). Methods A total of 310 patients with CSVD admitted from June 2022 to June 2025 were included. Montreal Cognitive Assessment Scale (MoCA) was applied for cognitive function assessment, and Scale for Outcomes in PD for Autonomic Symptoms (SCOPA-AUT) was used to evaluate autonomic nerve function damage. The incidence rate of autonomic nerve function damage, total score and dimensions scores of SCOPA-AUT were counted. According to the presence or absence of autonomic nerve function damage, the enrolled patients were categorized into damage group and non-damage group. The total score of MoCA and scores of dimensions were compared between both groups. Pearson correlation analysis model was utilized to analyze the correlation between total score of MoCA and scores of dimensions of SCOPA-AUT in patients with CSVD. Results Among the 310 patients, 63.87% cases (198 / 310) had autonomic nerve function damage. The SCOPA-AUT total score and scores of dimensions of gastrointestinal function, urinary system function, cardiovascular function, body temperature regulation, pupil movement and sexual function were (34.16 ± 10.41) points, (10.25 ± 3.31) points, (9.44 ± 2.89) points, (4.02 ± 1.66) points, (6.41 ± 2.35) points, (1.35 ± 0.49) points and (2.69 ± 0.81) points. The total score of MoCA and scores of language function, naming, delayed recall and attention in the damage group were lower than those in the non-damage group (P < 0.05). Pearson correlation analysis results revealed that the total score, urinary system score, cardiovascular function score and body temperature regulation score of SCOPA-AUT were negatively correlated with the total score of MoCA (r = -0.545, -0.598, -0.607, -0.615, P < 0.05), and the gastrointestinal function score, pupil movement score and sexual function score were not significantly associated with total score of MoCA (P > 0.05). Conclusion The risk of autonomic nerve function damage is high in patients with CSVD, and it involves multiple systems and is closely related to the cognitive function of patients.

Objective To explore the potential mechanism of Polygonum cuspidatum in alleviating silicosis using network pharmacology, molecular docking, and experimental validation. Methods i) The targets of active components of Polygonum cuspidatum and silicosis-related targets were retrieved from multiple databases. The overlapping targets were imported into Venny2.1.0 and STRING platforms. "Polygonum cuspidatum-active components-potential therapeutic targets for silicosis" network was constructed and core targets of Polygonum cuspidatum that can alleviate silicosis were identified using the Cytoscape3.10.2 software. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed using the DAVID database, and molecular docking was conducted with AutoDock software. ii) Human embryonic lung fibroblast MRC-5 cells were divided into three groups. Cells in the control group were cultured in high-glucose Dulbecco's modified Eagle's medium containing 10.00% (V/V)fetal bovine serum. Cells in the silica group were treated with silica suspension at a final concentration of 150 μg·cm² (equivalent to 75 mg/L) for 48 hours. Cells in the silica + β-sitosterol group were first treated with silica suspension for 24 hours, then were cultured in medium containing β-sitosterol at a mass concentration of 50 μg/L for another 24 hours. Immunofluorescence assay and Western blotting were used to detect the effects of β-sitosterol, a core component of Polygonum cuspidatum, on the expression of phosphorylated protein kinase B (p-AKT), B-cell lymphoma-2 (BCL-2), and α-smooth muscle actin (α-SMA) in cells. Results i) A total of ten main active components of Polygonum cuspidatum, 840 targets of the active components, and 231 potential therapeutic targets for silicosis were screened through retrieval. A total of 10 core therapeutic targets were further screened, including tumor protein p53, serine/threonine protein kinase B1 (AKT1), heat shock protein 90-α, interleukin (IL)-6 , tumor necrosis factor, Src tyrosine kinase, estrogen receptor 1, epidermal growth factor receptor, BCL-2, and IL-1β. KEGG enrichment analysis yielded 178 related target pathways, among which, the phosphatidylinositol 3-kinase-protein kinase B (PI3K/AKT) signaling pathway was most relevant to silicosis. Molecular docking results showed that the top five compounds of Polygonum cuspidatum with high degree centrality, including quercetin, luteolin, physovenine, rhein, and β-sitosterol, had strong binding affinities with core targets. Among them, β-sitosterol, a key component of Polygonum cuspidatum, ranked high in binding affinity to all core targets. Molecular docking visualization indicated that β-sitosterol ranked high in binding affinitiy with the core target proteins AKT1 and BCL-2. ii) Both immunofluorescence and Western blotting results showed that, the relative expression of p-AKT, BCL-2, and α-SMA proteins increased in MRC-5 cells of the silica group compared with the control group (all P<0.05), except for p-AKT detected by Western blotting. Compared with the silica group, the relative expression levels of p-AKT, BCL-2, and α-SMA proteins in the silica+β-sitosterol group decreased (all P<0.05). Conclusion β-sitosterol, the core component of Polygonum cuspidatum, may alleviate silicosis fibrosis via the PI3K/AKT signaling pathway.

ObjectiveTo construct and validate a predictive model for hepatic encephalopathy （HE） in patients with end-stage liver disease （ESLD） by combining key indicators such as cytokines and Model for End-Stage Liver Disease （MELD） score， and to provide evidence-based support for the early identification of high-risk populations and the optimization of intervention strategies in clinical practice. MethodsA retrospective analysis was performed for 2 167 patients with ESLD who were admitted to The Third People’s Hospital of Kunming from January 2022 to December 2024， the patients were divided into a training set with 1 517 patients and a validation set with 650 patients at a ratio of 7∶3 using the stratified random sampling method. A univariate analysis and a least absolute shrinkage and selection operator （LASSO） regression analysis were performed for the training set to identify potential influencing variables， and then a binary Logistic regression model was constructed to investigate the independent influencing factors for HE in ESLD patients. A nomogram prediction model was established based on this regression model， and the Hosmer-Lemeshow goodness-of-fit test was performed. The receiver operating characteristic （ROC） curve， calibration curves， decision curve analysis， and clinical impact curve were used to comprehensively evaluate the degree of fit， accuracy， consistency， and clinical practicability of the predictive model derived from the training set. The Mann-Whitney U test was used for comparison of non-normally distributed quantitative data between two groups. The chi-square test or Fisher exact test was used for comparison of categorical data between two groups. ResultsThe univariate analysis showed that there were significant differences between the study group and the control group in age， sex， blood ammonia， lymphocytes， hemoglobin， platelet count， prothrombin time， fibrinogen， international normalized ratio， total bilirubin， aspartate aminotransferase， total protein， albumin， prealbumin， alkaline phosphatase， cholinesterase， total bile acid， triglyceride， total cholesterol， high-density lipoprotein， low-density lipoprotein， blood glucose， CD3⁺ T cells， CD4⁺ T cells， CD8⁺ T cells， high-sensitivity C-reactive protein， carcinoembryonic antigen， triiodothyronine， thyroxine， free triiodothyronine， free thyroxine， interleukin-1β， interleukin-5， interleukin-6， interleukin-8， interleukin-12p70， interleukin-17， interferon-γ， and MELD score （all P<0.05）. The LASSO regression analysis identified nine variables of age， blood ammonia， albumin， prealbumin， cholinesterase， total cholesterol， thyroxine， interleukin-17， and MELD score， and the binary Logistic regression analysis showed that blood ammonia， interleukin-17， and MELD score were independent risk factors for HE in ESLD patients， while age and thyroxine were independent protective factors （all P<0.05）. A nomogram model was constructed based on these five variables. The Hosmer-Lemeshow goodness-of-fit test in the training set showed a good degree of fit （P=0.207）， with a McFadden’s pseudo-R² of 0.184， suggesting that the model had acceptable explanatory power； the Hosmer-Lemeshow goodness-of-fit test in the internal validation set further confirmed the calibration stability of the model （P=0.067）， suggesting that the model had a good degree of fit in independent data. The model had an area under the ROC curve of 0.784 in the validation set， with a sensitivity of 0.710 and a specificity of 0.752. The mean absolute error of the calibration curve was 0.067， and decision curve analysis and clinical impact curve showed that the nomogram model had positive net benefit and good clinical practicability. ConclusionThe nomogram model constructed based on age， blood ammonia， thyroxine， interleukin-17， and MELD score for predicting HE in patients with ESLD has a good degree of fit， high accuracy and consistency， and excellent clinical practicability.

Objective To explore the diagnostic value of soluble C5b-9 (sC5b-9) for delayed graft function (DGF) following kidney transplantation. Methods Clinical data of 49 kidney transplant recipients who underwent sC5b-9 detection at the Second People’s Hospital of Shanxi Province between January 2024 and December 2025 were retrospectively analyzed. Recipients were divided into the DGF group (n=25) and the non-DGF group (n=24) according to the occurrence of DGF. Baseline characteristics and serum sC5b-9 levels were compared between the two groups. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic efficacy of sC5b-9 for DGF. A restricted cubic spline model was adopted to investigate the association between sC5b-9 and DGF. Results Among the 49 recipients, DGF occurred in 25 patients. Compared with the non-DGF group, the DGF group presented a higher proportion of male patients, a higher incidence of adverse transplant outcomes, and elevated final serum creatinine levels (all P<0.05). Within 30 days after transplantation, sC5b-9 concentrations were significantly higher in the DGF group than those in the non-DGF group (P<0.001). ROC analysis revealed that the area under the curve (AUC) of sC5b-9 for diagnosing DGF was 0.81, with a 95% confidence interval (CI) of 0.68-0.92, and the optimal cutoff value was 265.7 ng/mL. Recipients with elevated sC5b-9 (≥265.7 ng/mL) had a significantly higher incidence of DGF than those with low sC5b-9 levels (<265.7 ng/mL) (P<0.001). Recipients with adverse outcomes exhibited significantly higher sC5b-9 levels than those without adverse outcomes (P<0.001), and the AUC of sC5b-9 for identifying adverse outcomes was 0.82 (95%CI 0.63-0.95). A significant nonlinear correlation was observed between sC5b-9 and final serum creatinine (P<0.001). Conclusions Elevated sC5b-9 is correlated with the development of DGF after kidney transplantation and exhibits favorable diagnostic performance. It may serve as a potential biomarker for predicting early allograft dysfunction and adverse outcomes in kidney transplant recipients.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective:To analyze the diversity of Duffy blood group gene among ethnic Hui population from Henan Province using PacBio long-read sequencing technique.Methods:Randomly select 30 individuals with three generations of Hui ancestry from Henan as the study subjects. Full-length sequences of the Duffy blood group gene were obtained through PacBio long-read sequencing. Distribution of the predicted phenotype and genotype frequency were determined, and the linkage between Duffy haplotypes and variation sites was analyzed. Genetic diversity, natural selection pressure, and population genetic characteristics were evaluated. This study was approved by the Medical Ethics Committee of the Second Affiliated Hospital of Zhengzhou University (Ethics No. 202223).Results:The predicted Duffy blood group phenotype in the Henan Hui population was predominantly Fy(a+ b-). Three novel SNPs in the FY*01 allele were identified, with a total frequency of 13.33%, among which FY*01.NEW1 (c.199C>T) was the most common. A total of 32 variant sites were identified, with 28 located in intronic regions, indicating that genetic diversity was primarily concentrated in introns. The Duffy blood group gene was under negative selection pressure ( dN/ dS < 1, Tajima′s D, Fu and Li′s D*& F* significantly deviated from 0), suggesting overall conservation. The allele frequencies of Duffy blood group in the Henan Hui population was similar to that of the Xinjiang Hui, Xinjiang Kazakh, Inner Mongolia Mongolian, and Yuncheng Han populations, but significantly different from those of most Han and other ethnic groups ( P<0.05). Conclusion:This study revealed the characteristics of the Duffy blood group gene among the Henan Hui population and demonstrated the significant advantages of PacBio long-read sequencing technique in haplotype analysis, genetic diversity study, and novel mutation identification.
