ObjectiveTo investigate the molecular mechanism by which Feiyanning formula（FYN） regulated exosomal miR-328 to suppress the invasion and metastasis of lung cancer. MethodsIn vitro models using low-metastatic 95C and high-metastatic 95D lung cancer cell lines， along with isolated exosomes， were established. Initially， 95C and 95D cells were cultured， and exosomes were isolated from their supernatants. The exosomes were identified using transmission electron microscopy （TEM）， nanoparticle tracking analysis （NTA）， and Western blot. Exosome uptake assays confirmed that both 95C and 95D cells could internalize exosomes derived from lung cancer patients' plasma. Cell counting kit-8 （CCK-8） assays were performed to assess the inhibitory effects of FYN （0， 0.1， 0.2， 0.4， 0.8， 1.6， 3.2， 6.4 g·L^-1） on 95C and 95D cell proliferation. Subsequent experiments were divided into three groups of control， low-dose FYN （1 g·L^-1）， and high-dose FYN （2 g·L^-1） groups. Wound-healing and Transwell assays were used to evaluate the inhibitory effects of FYN on the migration and invasion of 95C and 95D cells. Western blot was employed to detect the protein expression levels of Janus kinase 2 （JAK2）， signal transducer and activator of transcription 3 （STAT3）， cellular oncogene Fos （c-Fos）， and nuclear factor of activated T cells 1 （NFATc1）. The mRNA expression of miR-328 was measured by Real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsLung cancer plasma-derived exosomes （EXO） enhanced the migration， invasion， and miR-328 expression levels in 95C and 95D cells （P<0.05， P<0.01）. FYN inhibited the proliferation， invasion， and metastasis of 95C and 95D cells in a dose-dependent manner （P<0.01）， with more pronounced effects on 95C cells. Additionally， FYN downregulated exosomal miR-328 expression and suppressed the protein levels of JAK2， STAT3， and its downstream target genes c-Fos and NFATc1 （P<0.01）. ConclusionFYN may inhibit lung cancer metastasis by downregulating exosomal miR-328 expression， potentially through the STAT3/c-Fos/NFATc1 signaling pathway. Further studies are warranted to elucidate its detailed mechanisms and facilitate clinical application， providing insights into traditional Chinese medicine-based strategies for lung cancer treatment.

Objective To investigate the regulatory role and underlying mechanism of the long non-coding RNA (LncRNA) LINC01430 in the inhibitory effect of sanguinarine on non-small cell lung cancer (NSCLC). Methods Differentially expressed LncRNAs and coexpressed target genes in A549 and H1975 cells before and after sanguinarine treatment were identified through high-throughput lncRNA sequencing. LINC01430 expression and its prognostic value were analyzed by using the TCGA database and experimental validation. An LINC01430-overexpressing A549 cell model was established, and CCK-8, TUNEL, RT-qPCR, Western blot analysis, and dual-luciferase reporter assays were performed to evaluate the influence of LINC01430 overexpression on sanguinarine-mediated cell proliferation, apoptosis and NOX4/IL-6 expression. Results A total of 361 differentially expressed LncRNAs, among which LINC01430 was significantly downregulated (P<0.001), were identified after sanguinarine treatment. Pathway enrichment analysis revealed pathways associated with oxidative stress and inflammation, and the mRNA and protein levels of the target genes NOX4 and IL-6 were markedly reduced (P<0.05, P<0.01). LINC01430 exhibited high expression in NSCLC tissues and cell lines (P<0.05), with a trend toward poor prognosis (HR=1.15). The overexpression of LINC01430 significantly attenuated the inhibitory effect of sanguinarine on cell proliferation and the promoting effect on apoptosis in NSCLC cells (P<0.01) and partially reversed the downregulation of NOX4 and IL-6 induced by sanguinarine (P<0.05). LINC01430 directly activated IL-6 promoter transcriptional activity (P<0.05). Meanwhile, its effect on the NOX4 promoter showed an upward trend without statistical significance. Conclusion Sanguinarine may suppress NSCLC by downregulating LINC01430 to inhibit NOX4/IL-6 signaling. LINC01430 represents a promising target for NSCLC therapy.

Under the current upsurge of cross-disciplinary research between artificial intelligence （AI） and traditional Chinese medicine （TCM）， the inheritance of academic thought in TCM is confronted with the deep-seated predicament of cognitive paradigm dislocation. The existing AI model is based on the classical reasoning mode of formal logic and statistical probability， which is difficult to adapt to the nonlinear and holistic cognitive logic of TCM with image-based thinking and syndrome-differentiated treatment as the core， resulting in systematic misreading and loss of the core essence in digital inheritance. Based on this， this paper proposes to construct a new cognitive model oriented towards the context of TCM. Its essence is not to have AI imitate the thinking of TCM， but to establish an auxiliary understanding framework based on semantic mapping and relational reasoning. It is advocated that the role of AI should be reconstructed from a knowledge substitute to a clinical interactor， and its application boundary in the inheritance of TCM wisdom should be clarified. By establishing the theoretical framework and practical path of human-computer collaboration， this paper aims to provide a scientific basis for realizing the deep integration of AI technology and the academic thought in TCM.

Objective To analyze the expression and prognostic association of transmembrane 7 superfamily member 2(TM7SF2)in colorectal cancer using bioinformatics techniques.Methods The differential expression levels and clinical relevance of TM7SF2 mRNA in normal tissues and colorectal tumor tissues were analyzed using The Cancer Genome Atlas(TCGA)database.Evaluate the impact of TM7SF2 gene expression levels on patient prognosis through univariate and multivariate Cox regression analysis.Gene sets were download and score biological function changes by using the gene set variation analysis algorithm.Patients were divide into high and low expression groups based on TM7SF2 gene expression levels and the differences in signaling pathways with gene set enrichment analysis(GSEA)analyzed;use the CIBERSORT tool to assess the relationship between tumor immune cell infiltration and TM7SF2,apply the genomics of drug sensitivity in cancer(GDSC)database to predict the drug chemosensitivity of this gene,and describe the association between TM7SF2 gene expression and clinical indicators in colorectal cancer patients.Results Compared with normal tissues,the expression level of TM7SF2 in tumor tissues was significantly upregulated.Survival analysis indicates that high expression of the TM7SF2 gene was associated with poor prognosis in colorectal cancer patients.Through univariate and multivariate Cox regression model analysis,it was found that the expression level of TM7SF2 was a risk factor for the prognosis of colorectal cancer.Enrichment analysis suggested that TM7SF2 may play a role in pathways such as DNA replication,Wnt signaling pathway,and pentose phosphate pathway.TM7SF2 was positively correlated with regulatory T cells and CD8+T cells,and negatively correlated with memory CD4+T cells and neutrophils.In terms of drug sensitivity,TM7SF2 is correlated with the sensitivity to Camptothecin,Cisplatin,Docetaxel,Nilotinib,Olaparib,and Axitinib.Regression analysis showed that the contribution of TM7SF2 expression distribution to different clinical indicators varies.Conclusion TM7SF2 is highly expressed in colorectal cancer tissues and is associated with poor patient prognosis,can be used as a prognostic biomarker.

Objective To explore the mechanism of Kangliu Zengxiao Jiandu Prescription(KLJD)in enhancing the efficacy of cisplatin chemotherapy in non-small cell lung cancer(NSCLC)through network pharmacology and in vivo/in vitro experiments.Methods Components of KLJD were screened via the TCMSP database to identify active components and potential targets.Lung cancer-related genes were obtained from the GeneCards and OMIM databases.GO and KEGG pathway enrichment analysis was performed on drug-disease intersection targets using the Metascape database;molecular docking was performed between core target proteins and main active components.A Lewis lung cancer mouse model was established,and intervened with KLJD and cisplatin.Organ indexes and tumor inhibition rate were counted,and Western blot and RT-PCR were used to detect the expressions of key pathway target proteins and mRNA;A549 and H1299 cells were intervened with KLJD,and Western blot was used to detect key target protein expressions.Results Network pharmacology identified 74 active components and 20 key targets of KLJD,primarily involved in biological processes such as cell proliferation and inflammatory response,and pathways in cancer and PI3K/AKT signaling pathway;molecular docking revealed stable binding between EGFR and major compounds.Animal experiments demonstrated that,compared with the model group,the KLJD group showed significantly higher tumor inhibition rate(P<0.01)and downregulation of EGFR,AKT and PI3K protein and mRNA expression in tumor tissues(P<0.05).Compared with the cisplatin group,the combination group exhibited significantly enhanced tumor inhibition rate(P<0.01),elevated thymic and splenic indices(P<0.01),and decreased EGFR,PI3K and AKT protein and mRNA expressions(P<0.01).Cell experiments showed that KLJD concentration-dependently inhibited A549 and H1299 cell proliferation(IC50:14.72 mg/mL and 14.68 mg/mL,respectively).Combined with cisplatin,KLJD synergistically down-regulated EGFR PI3K and AKT protein expressions(P<0.01).Conclusion KLJD effectively enhances cisplatin's chemotherapeutic efficacy in NSCLC by inhibiting the EGFR/PI3K/AKT pathway while improving immune organ function.Its mechanism likely involves multi-target regulation,including suppression of tumor proliferation,promotion of apoptosis,and modulation of the immune microenvironment.

Objective To explore the characteristics of TCM syndromes in patients with obesity with metabolic associated fatty liver disease(MAFLD).Methods TCM Symptom Collection Form was developed to collect the clinical symptoms of obesity patients who attended the Department of Acupuncture and Moxibustion of Beijing Hospital of Traditional Chinese Medicine,Capital Medical University,from July to December of 2024.Factor analysis and clustering analysis were used to explore the distribution law of different syndrome elements and TCM syndromes.Results A total of 309 obese patients(221 with MAFLD)were included,with 20 symptoms with a frequency of≥5%.Factor analysis suggested that there was a significant difference between the two groups in the pathogenic syndrome elements of qi stagnation,yin deficiency,qi deficiency,hyperactivity of yang,yang deficiency,dampness,dynamic wind,and the locus of disease syndrome elements of the spleen and the heart spirit(P<0.05).Clustering analysis showed that the syndrome types of patients with MAFLD were mainly the syndrome of liver and stomach stagnation and heat,the syndrome of spleen deficiency and stomach heat,and the syndrome of spleen and kidney deficiency;the syndrome types of patients without MAFLD were mainly spleen-stomach qi stagnation,gastrointestinal excess-heat,spleen-deficiency-dampness obstruction,and spleen-kidney deficiency.Conclusion Patients of obesity with MAFLD are more likely to have the co-existence of the pathogenesis of damp-heat obstruction and spleen-kidney deficiency.

Objective:To observe and analyze the ocular clinical features and pathogenic genes of horizontal gaze palsy with progressive scoliosis (HGPPS).Methods:A pedigree study was conducted.Two families with HGPPS diagnosed by ophthalmology examination at Henan Children's Hospital from November 2023 to April 2024 were included, with 3 people from two generations in each family.Medical history and family history of the subjects were inquired.Vision acuity, diopter, anterior segment, intraocular pressure, wide-angle laser scanning ophthalmoscopy, optical coherence tomography, visual evoked potential (VEP), electroretinogram (ERG), ocular B-ultrasound, full spine AP+ lateral view, orbit+ skull+ cervical spine+ thoracic spine+ lumbosacral spine MRI plain scan were performed on the subjects.Whole genomic DNA was extracted from 2 ml of peripheral venous blood collected from the subjects, and gene sequencing was performed using whole exome sequencing (WES) technology.Suspicious pathogenic variant loci were verified by Sanger sequencing, and the pathogenicity of gene variant loci was analyzed according to the ACMG standards and guidelines for the interpretation of sequence variants.This study followed the Declaration of Helsinki.The study protocol was reviewed and approved by the Ethics Committee of Henan Children's Hospital (No.2024-KY-0024).All subjects and guardians signed informed consent forms and were informed of relevant matters before genetic testing.Results:The proband from family 1 was male, 3 years and 2 months old.At the age of 6 months, he was found to have head tilted to the left with a right scoliosis of the spine centered on T11-12 and no obvious abnormalities on VEP and ERG examinations.The proband from family 2 was male, 3 years and 4 months old, with a left scoliosis of the spine centered on T12.Both probands developed horizontal fixation paralysis, unable to rotate eye outward, slightly limited inward rotation, left eye hypertropia, mild horizontal nystagmus, normal vertical eye movement, backward development of major movements, and normal vision, anterior segment and fundus.MRI examination showed that the medulla oblongata was butterfly shaped, and a brainstem fissure could be seen in the center of the medulla oblongata.The genetic testing showed that the proband from family 1 had compound heterozygous variations c. 1054delC/p.Gln352Serfs *90 (M1) in exon 7 and c. 1219G>T/p.Gly407Cys (M2) in exon 8 of ROBO3 gene.The father of the proband carried M1 and the mother of the proband carried M2.The proband from family 2 had compound heterozygous variations c. 1888C>T/p.R630X (M3) in exon 12 and c. 2684C>A/p.A895E (M4) in exon 17 of ROBO3 gene.M1 and M3 were possible pathogenic, and M2 and M4 were of unknown clinical significance, and prediction software predicted M2 and M4 were harmful variations. Conclusions:The main clinical features of two HGPPS pedigree are horizontal fixation paralysis and progressive scoliosis, accompanied by nystagmus and strabismus.MRI shows brainstem fissure in the central medullary area.Four variants are novel variants, which increases the variation spectrum of ROBO3 gene.

BACKGROUND:Previous studies by the research group have shown that core proteoglycan in Cornus Cervi Col la can enter the bone,promote the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells,and has a good repair effect on steroid-induced osteonecrosis of the femoral head.OBJECTIVE:To investigate the therapeutic effect and potential mechanism of Cornus Cervi Colla on steroid-induced osteonecrosis of the femoral head in rats by fecal non-targeted fecal metabolomics.METHODS:Thirty SD rats were randomly divided into three groups using a random number table method:the control group(n=10)was injected with normal saline into the right gluteal muscle(injected on the first 3 days of each week for 3 consecutive weeks),and was given pure water gavage(once a day for 6 consecutive weeks).The model group(n=10)was injected with methylprednisolone sodium succinate into the right gluteal muscle(injected on the first 3 days of each week for 3 consecutive weeks)to establish a steroid-induced osteonecrosis of the femoral head model,and was given pure water gavage(once a day for 6 consecutive weeks).The Cornus Cervi Co I la group(n=10)was also established with a steroid-induced osteonecrosis of the femoral head model,and was given Cornus Cervi Col la gavage(once a day for 6 consecutive weeks).After gavage,cecal feces and femoral heads were collected for fecal metabolomics analysis and bone tissue Micro-CT and hematoxylin-eosin staining,respectively.RESULTS AND CONCLUSION:(1)Metabolomics analysis results showed that there were 233 differential metabolites between the Cornus Cervi Col la and model groups,with 65 significantly differing and clearly annotated metabolites.Lipid and amino acid metabolites were significantly increased,with bile acids,sulfated steroids,ephedrine,hypoxanthine,betaine,L-carnitine,B-mouse bile acid,cytidine,4-pyridoxic acid,taurine,N-acetyl-d-glucosamine,and butyric acid being the most impacted(variable weight value VIP＞5).The metabolic pathways of taurine and hypotaurine were crucial in the metabolic regulatory network(pathway impact=0.428 57).(2)Micro-CT scanning results of bone tissue showed that the femoral heads of rats in the model group and the Cornus Cervi Col la group had different degrees of damage;the femoral head contour was irregular;the trabeculae in the subchondral bone of the femoral head were missing and disordered,and some cystic structures were visible.Compared with the model group,the degree of trabecular damage in the rats of the Cornus Cervi Colla group was milder.Hematoxylin-eosin staining results showed that the trabeculae in the subchondral bone of the femoral heads of rats in the model group and the Cornus Cervi Colla group were sparse or interrupted,and the empty bone lacuna rate and adipocyte invasion were increased.Compared with the model group,the empty bone lacuna rate and adipocyte invasion in the subchondral bone of the femoral heads of rats in the Cornus Cervi Colla group were reduced.(3)These results conclude that Cornus Cervi Colla potentially mitigates steroid-induced osteonecrosis of the femoral head through the metabolic processes involving taurine and associated pathways.

ObjectiveTo explore the mechanism of the anti-cancer compound formula Feiyanning in inhibiting epithelial-mesenchymal transition （EMT） and invasion and metastasis of non-small cell lung cancer （NSCLC）. MethodsCell proliferation and activity were assessed using the cell counting kit-8（CCK-8） assay to evaluate the effect of Feiyanning on the proliferation of A549 and H1299 cells. Wound healing and Transwell assays were conducted to examine Feiyanning's impact on the metastasis of A549 and H1299 cells. The effects of Feiyanning on EMT and the transforming growth factor-β₁ （TGF-β₁）/Smad signaling pathway proteins in A549 and H1299 cells were detected by Western blot. Exogenous TGF-β₁ was used to induce EMT in A549 and H1299 cells. The effects of Feiyanning on TGF-β₁-induced NSCLC cell metastasis， EMT， and the TGF-β₁/Smad pathway proteins were assessed by wound healing assay， Transwell assay， and Western blot. In vivo， an A549 lung metastasis model was established via tail vein injection in nude mice. A total of 28 SPF male nude mice were randomly divided into four groups： Model （NC） group， Feiyanning low-dose （FYN1） group， Feiyanning high-dose （FYN2） group， and the positive control group （TGF-β receptor kinase inhibitor SB431542 group）. The corresponding interventions were performed. After 40 days， the mice were euthanized， and lung metastases were analyzed. The expression of E-cadherin， N-cadherin， p-Smad2， and p-Smad3 in each group was detected by immunohistochemistry （IHC）. ResultsAfter Feiyanning intervention， compared to the blank group， Feiyanning inhibited the proliferation of A549 and H1299 cells in a concentration-dependent manner （P<0.01）. The metastasis ability of Feiyanning-treated cells was significantly decreased compared to the blank group （P<0.01）. The expression of EMT marker proteins N-cadherin and zinc finger transcription factors （Zeb1， Snail， Slug） was significantly reduced in the Feiyanning groups compared to the blank group （P<0.05， P<0.01）. The expression of p-Smad2/3， Smad2/3， TβRI， and TβRⅡ， key proteins in the TGF-β₁/Smad signaling pathway， was also significantly decreased （P<0.01）. In the TGF-β₁-induced EMT model， compared to the TGF-β₁ group， the cell metastasis ability in the Feiyanning groups was reduced （P<0.01）， and the expression levels of N-cadherin， Zeb1， Snail， and Slug were significantly lower （P<0.01）. The expression levels of p-Smad2/3， Smad2/3， TβRI， and TβRⅡ were also significantly reduced （P<0.01）. In vivo results showed that compared to the model group， the number of lung metastases in the FYN1， FYN2， and SB431542 groups was reduced （P<0.01）， and the range of cell infiltration was narrowed. Immunohistochemical results showed that compared to the model group， the expression of E-cadherin in the FYN1， FYN2， and SB431542 groups was increased （P<0.01）， the expression of N-cadherin decreased （P<0.05， P<0.01）， and the expression of p-Smad2 and p-Smad3， key proteins of the TGF-β₁/Smad pathway， was reduced （P<0.01）. ConclusionFeiyanning inhibits the invasion and metastasis of NSCLC cells and EMT. The mechanism is related to the inhibition of TGF-β₁/Smad signaling pathway.
