By analyzing the current application of multi-modal data in the diagnosis of gastric "inflammation-cancer" transformation, this study explored the feasibility and strategies for constructing a disease-syndrome integrated diagnosis and treatment system. Based on traditional Chinese medicine (TCM) phenomics, we proposed utilizing multi-modal data from literature research, cross-sectional studies, and cohort follow-ups, combined with artificial intelligence technology, to establish a multi-dimensional diagnostic and treatment index system. This approach aims to uncover the complex pathogenesis and transformation patterns of gastric "inflammation-cancer" progression. Additionally, by dynamically collecting TCM four-diagnostic information and modern medical diagnostic information through a long-term follow-up system, we developed three major modules including information extraction, multi-modal phenotypic modeling, and information output, to make it enable real-world clinical data-driven long-term follow-up and treatment of chronic atrophic gastritis. This system can provide technical support for clinical diagnosis, treatment evaluation, and research, while also offering insights and methods for intelligent TCM diagnosis.

AIM:To investigate the molecular mechanism underlying ferroptosis induced by celastrol(Cel)in huamn pancreatic cancer cell line PANC-1.METHODS:The viability of PANC-1 cells was analyzed by MTT assay,and the effects of Cel on cell proliferation were analyzed using EdU and colony formation assays.Flow cytometry and fluores-cence microscopy were used to assess and observe changes in lipid reactive oxygen species(ROS)levels,respectively,while the levels of malondialdehyde(MDA),glutathione(GSH)and Fe2+were measured using specific kits.The protein expression of glutathione peroxidase 4(GPX4)was evaluated by Western blot,and GPX4 ubiquitination was measured by immunoprecipitation.RESULTS:It was found that the viability,proliferation and colony formation in PANC-1 cells de-creased gradually as the concentration of Cel increased.Addition of Cel alone to the cells reduced both cell rounding and viability,while treatment with ferrostatin-1(Fer-1)alone or in combination with Cel had no effect on either cell morpholo-gy or viability.Fluorescence staining of lipid ROS with BODIPYTM 581/591 C11 followed by flow cytometry analysis showed significantly increased levels of green fluorescence indicative of oxidized lipid ROS,which were further increased after treatment of the cells with Cel.Treatment of the cells with both Cel and Fer-1 reduced the green fluorescence and lip-id ROS levels.Treatment with Cel also increased the levels of MDA and Fe2+,relative to the controls,which reducing the levels of GSH,while addition of both Cel and Fer-1 to the cells restored the levels of MDA,Fe2+,and GSH to those of the control group.CONCLUSION:Treatment with Cel reduces the proliferation of pancreatic cancer cells by inducing fer-roptosis through promoting the ubiquitination and degradation of GPX4.

Objective:To investigate the clinical outcome of endovascular treatment vs. drug treatment in patients with symptomatic non-acute long-segment occlusion of the internal carotid artery. Methods:Based on prospective cohort registration research data, patients with symptomatic non-acute long-segment occlusion of internal carotid artery were retrospectively included. They were divided into a drug treatment group and an endovascular treatment group according to the actual treatment received. The latter was further divided into a successful recanalization group and an unsuccessful recanalization group. The endpoint events included ipsilateral ischemic stroke, any stroke, and all-cause death. Multivariate logistic regression analysis was used to compare the endpoint events between groups during the perioprocedural period (within 30 days), and multivariate Cox proportional hazards model was use to compare the endpoint events between the groups during the long-term follow-up. Results:A total of 684 patients were included, of which 570 (83.33%) were male, median aged 63 years (interquartile range, 56-70 years). Three hundred and fifty-three patients (51.6%) received drug treatment; 331 (48.4%) received endovascular treatment, of which 161 (48.6%) had successful recanalization. The median follow-up time was 1 223 days (interquartile range, 646.5-2 082 days), with 109 patients (15.9%) experiencing stroke recurrence events (including 87 ipsilateral ischemic stroke) and 78 (11.4%) experiencing all-cause mortality. The risk of any stroke during the perioprocedural period in the successful recanalization group was significantly higher than that in the drug treatment group (odds ratio 3.679, 95% confidence interval 1.038-13.036; P=0.044), but the risk of ipsilateral ischemic stroke recurrence (risk ratio 0.347, 95% confidence interval 0.152-0.791; P=0.012) and all-cause mortality (risk ratio 0.239, 95% confidence interval 0.093-0.618; P=0.003) during the long-term follow-up were significantly lower than those in the drug treatment group. Conclusions:In patients with symptomatic non-acute long-segment occlusion of the internal carotid artery, endovascular treatment can increase the risk of stroke recurrence within 30 days, but successful recanalization can reduce the risks of long-term ipsilateral ischemic stroke recurrence and all-cause mortality.

ObjectiveTo investigate the effect of linalool against acute liver injury induced by aflatoxin B1(AFB1) in rats and explore its protective mechanism. MethodTwenty male SPF SD rats were randomly divided into three groups: Control (n=6), AFB1 (n=7), and linalool (n=7) groups. Linalool solution (200 mg·kg-1) was administered preventatively for 14 days, while the control and AFB1 groups intragastrically received an equivalent volume of double distilled water. After preventative administration of linalool, AFB1 solution (1 mg·kg-1, dissolved in saline) was intraperitoneally injected for two consecutive days to induce acute liver injury in rats. Samples were collected and processed 14 days after model establishment. Pathological changes in liver tissue of rats were observed using Hematoxylin-eosin(HE) staining and Masson staining. Biochemical detection was performed to measure the levels of alanine transaminase(ALT), aspartate transaminase(AST), γ-glutamyl transferase(GGT), lactate dehydrogenase(LDH), alkaline phosphatase(ALP), total bilirubin(TBil), direct bilirubin(DBil), indirect bilirubin(IBil), malondialdehyde(MDA), superoxidedismutase(SOD), catalase(CAT) , glutathione(GSH), Fe3+, and Fe2+ in the liver tissue. Western blot was adopted to assess protein expression levels of nuclear factor-erythroid 2-related factor 2(Nrf2) and heme oxygenase-1(HO-1). Molecular docking was performed to verify the binding between linalool and key proteins of the Nrf2/HO-1 signaling pathway. Molecular dynamics techniques were used to confirm the stability and affinity of linalool binding with key proteins of the Nrf2/HO-1 signaling pathway. ResultPathological results showed that compared to that in the AFB1 group, the liver structure in the linalool group tended to be normal, with a significant decrease in blue collagen fibers. The linalool group exhibited significantly reduced levels of ALT, AST, GGT, LDH, ALP, TBil, DBil, and IBil (P<0.01), Fe3+ and Fe2+ content, and oxidative stress marker MDA (P<0.01). The levels of antioxidants SOD, CAT, and GSH significantly increased (P<0.01). Molecular docking showed a molecular docking energy between linalool and Nrf2 and HO-1 targets of -5.495 6 and -5.199 4 kcal·mol-1(1 cal≈4.186 J), respectively. Molecular dynamics results indicated strong affinity in the binding of linalool with Nrf2 and HO-1. Western blot revealed a significant increase in Nrf2 protein expression (P<0.05) and a decrease in HO-1 protein expression (P<0.01) in the linalool group. ConclusionLinalool may protect against AFB1-induced acute liver injury by modulating the Nrf2/HO-1 ferroptosis signaling pathway to inhibit liver cell ferroptosis and regulate hepatic oxidative stress levels.

Objective To investigate the effect of MACC1 on RSL3-induced ferroptosis in colorectal cancer cells and explore its molecular mechanism.Methods MACC1 expression was detected in SW620,HCT116,LOVO and RKO cells using Western blotting.The effects of different concentrations of RSL3(an inducer of ferroptosis)or Fer-1(an inhibitor of ferroptosis)alone,or 10 μmol/L RLS3 combined with 10 μmol/L Fer-1,on viability of SW620 cells were examined using MTT assay.The survival of SW620 cells with mRNA interference of MACC1 was analyzed following treatment with RSL3,and RT-qPCR and Western blotting were performed to detect the changes in MACC1 expressions after RSL3 treatment at different concentrations and the changes in GPX4 expression after MACC1 knockdown.Flow cytometry and laser confocal microscopy were used to analyze the changes in ROS-induced lipid peroxidation in SW620 cells after MACC1 knockdown.Results SW620 cells had the highest MACC1 expression among the 4 colorectal cancer cell lines.Treatment with RSL3 significantly inhibited the viability of SW620 cells in a dose-dependent manner,while Fer-1 did not significantly affect the survival of SW620 cells.RSL3 alone reduced SW620 cell survival by 50%(P<0.01),and the combined treatment with RSL3 and Fer-1 caused no significant changes in cell survival(P>0.05).Treatment with RSL3 concentration-dependently suppressed MACC1 expressions at both the mRNA and protein levels in SW620 cells(P<0.01).MACC1 knockdown obviously enhanced the cytotoxic effect of RSL3,inhibited the expression of GPX4,and increased ROS-induced lipid peroxidation in SW620 cells(P<0.05).Conclusion MACC1 knockdown enhances RSL3-induced ferroptosis in cultured colorectal cancer cells by inhibiting the expression of GPX4.

ObjectiveMetabolomics was utilized to investigate the preventive effect of notoginseng total saponins(NTS) on aspirin(acetyl salicylic acid, ASA)-induced small bowel injury in rats. MethodFifty male SD rats were randomly divided into normal and model groups, NTS high-dose and low-dose groups(62.5, 31.25 mg·kg-1), and positive drug group(omeprazole 2.08 mg·kg-1+rebamipide 31.25 mg·kg-1), with 10 rats in each group. Except for the normal group, rats in other groups were given ASA enteric-coated pellets 10.41 mg·kg-1 daily to establish a small intestine injury model. On this basis, each medication group was gavaged daily with the corresponding dose of drug, and the normal group and the model group were gavaged with an equal amount of drinking water. Changes in body mass and fecal characteristics of rats were recorded and scored during the period. After 14 weeks of administration, small intestinal tissues of each group were taken for hematoxylin-eosin(HE) staining, scanning electron microscopy to observe the damage, and the apparent damage of small intestine was scored. Serum from rats in the normal group, the model group, and the NTS high-dose group was taken and analyzed for metabolomics by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-Q-Exactive Orbitrap MS), and the data were processed by multivariate statistical analysis, the potential biomarkers were screened by variable importance in the projection(VIP) value≥1.0, fold change(FC)≥1.5 or ≤0.6 and t-test P<0.05, and pathway enrichment analysis of differential metabolites was performed in conjunction with Human Metabolome Database(HMDB) and Kyoto Encyclopedia of Genes and Genomes(KEGG). ResultAfter 14 weeks of administration, the average body mass gain of the model group was lower than that of the normal group, and the NTS high-dose group was close to that of the normal group. Compared with the normal group, the fecal character score of rats in the model group was significantly increased(P<0.05), and compared with the model group, the scores of the positive drug group and the NTS high-dose group were reduced, but the difference was not statistically significant. HE staining and scanning electron microscopy results showed that NTS could significantly improve ASA-induced small intestinal injury, compared with the normal group, the small bowel injury score of the model group was significantly increased(P<0.01), compared with the model group, the small bowel injury scores of the NTS low and high dose groups were significantly reduced(P<0.05, P<0.01). Serum metabolomics screened a total of 75 differential metabolites between the normal group and the model group, of which 55 were up-regulated and 20 were down-regulated, 76 differential metabolites between the model group and the NTS groups, of which 14 were up-regulated and 62 were down-regulated. NTS could modulate three differential metabolites(salicylic acid, 3-hydroxybenzoic acid and 4-hydroxybenzoic acid), which were involved in 3 metabolic pathways, namely, the bile secretion, the biosynthesis of folic acid, and the biosynthesis of phenylalanine, tyrosine and tryptophan. ConclusionNTS can prevent ASA-induced small bowel injury, and the underlying mechanism may be related to the regulation of bile secretion and amino acid metabolic pathways in rats.
