Aim To explore the compatibility and po-tential mechanism of effective components of Biejia-Ezhu against triple negative breast cancer(TNBC)and verify it by experiments.Methods Effective compo-nents and targets of Biejia-Ezhu were obtained by TC-MSP and Swiss Target Prediction.Disease targets of TNBC were obtained from OMMI and GeneCards data-bases.The PPI network was constructed using STRING database.GO and KEGG path enrichment analysis was performed using DAVID database.Cytoscape3.9.1 software was used to construct the"drug-component-target-disease"network,screen key targets and compo-nents for molecular docking,and further verify the com-patibility of key components and targets in vitro.Re-sults ① A total of 71 effective components were iden-tified in the Biejia-Ezhu drug pair.There were 146 drug targets associated with the disease.A total of 113 signaling pathways were identified by KEGG analysis.The 71 potential active components of Biejia-Ezhu mainly acted on key targets such as mTORC1,ULK1,TNF,EGFR,ESR1,STAT3,HIF1A,and PTGS2.Mo-lecular docking results showed that glycine and curcu-min were the key active components of Biejia-Ezhu,and both had strong docking activity against key target proteins mTORC1 and ULK1.②The results of in vitro experiment showed that glycine combined with curcu-min significantly inhibited the proliferation and clonal formation ability of TNBC cells(P＜0.05),up-regula-ted the expression of autophagy marker LC3 Ⅱ/Ⅰ,down-regulated the expression of EGFR,down-regula-ted the expression of pathway protein mTORC1,p-mTOR,p-ULK1,and promoted the expression of path-way protein ULK1(P＜0.05).Conclusion The key component of Biejia-Ezhu against triple-negative breast cancer is glycine-curcumin,the mechanism of which may be related to the regulation of the mTORC1/ULK1 signaling pathway to promote autophagy.

Objective:To explore the influencing factors of post-percutaneous coronary intervention(PCI)positivity in young and middle-aged patients with acute myocardial infarction(AMI)and simultaneously assess its mediating effect in the relationship between illness-related shame and psychosocial adjustment.Methods:A total of 178 patients,who admit-ted in Cangzhou People's Hospital between October 2021 and December 2022 for AMI,underwent PCI,and were subse-quently defined as frailty after PCI,were selected.General demographic information survey forms,Patient Activation Measure(PAM),Social Impact Scale(SIS),and Psychosocial Adjustment to Illness Scale Self-Report(PAIS-SR)were applied to investigate the patients.Clinical data characteristics of the patients were analyzed.Pearson correlation analysis was conducted to investigate the association among PAM score,SIS score and PAIS-SR score.Multivariate linear stepwise regression analysis was employed to identify the influencing factors of positivity.The Bootstrap procedure in the Process plugin was used to validate the mediating effect of positivity between illness-related shame and psychosocial adjustment.Results:In this study,PAM score was(57.87±7.02)points,SIS score was(52.07±12.66)points,and PAIS-SR score was(61.07±10.58)points.Pearson correlation analysis indicated that PAM score was significant negatively correlated with SIS score and PAIS-SR score(r=-0.439,-0.504,P＜0.001 all),and SIS score was significant positively corre-lated with PAIS-SR score(r=0.722,P＜0.001).Multivariate linear stepwise regression analysis indicated that male(B=2.226,P=0.020),educational level(B=2.194,P=0.005)and stigma associated with illness(B=-0.210,P＜0.001)can influence the postoperative positivity of patients.Mediation effect analysis indicated that illness-related shame had a direct effect on psychosocial adjustment,accounting for 85.92％of the total effect,while positivity partially media-ted the relationship between illness-related shame and psychosocial adjustment with an effect size of 14.08％.Conclusion:Illness-related shame not only directly affects the psychosocial adjustment in frailty AMI patients after PCI,but also exerts an indirect influence on it through positivity.Medical staff should implement targeted strategies to enhance patients'positiv-ity,thereby reducing the negative impact of illness-related shame on psychosocial adjustment.

PURPOSE: To investigate the protective effect of sub-hypothermic mechanical perfusion combined with membrane lung oxygenation on ischemic hypoxic injury of yorkshire brain tissue caused by traumatic blood loss. METHODS: This article performed a random controlled trial. Brain tissue of 7 yorkshire was selected and divided into the sub-low temperature anterograde machine perfusion group (n = 4) and the blank control group (n = 3) using the random number table method. A yorkshire model of brain tissue injury induced by traumatic blood loss was established. Firstly, the perfusion temperature and blood oxygen saturation were monitored in real-time during the perfusion process. The number of red blood cells, hemoglobin content, NA⁺, K⁺, and Ca²⁺ ions concentrations and pH of the perfusate were detected. Following perfusion, we specifically examined the parietal lobe to assess its water content. The prefrontal cortex and hippocampus were then dissected for histological evaluation, allowing us to investigate potential regional differences in tissue injury. The blank control group was sampled directly before perfusion. All statistical analyses and graphs were performed using GraphPad Prism 8.0 Student t-test. All tests were two-sided, and p value of less than 0.05 was considered to indicate statistical significance. RESULTS: The contents of red blood cells and hemoglobin during perfusion were maintained at normal levels but more red blood cells were destroyed 3 h after the perfusion. The blood oxygen saturation of the perfusion group was maintained at 95% - 98%. NA⁺ and K⁺ concentrations were normal most of the time during perfusion but increased significantly at about 4 h. The Ca²⁺ concentration remained within the normal range at each period. Glucose levels were slightly higher than the baseline level. The pH of the perfusion solution was slightly lower at the beginning of perfusion, and then gradually increased to the normal level. The water content of brain tissue in the sub-low and docile perfusion group was 78.95% ± 0.39%, which was significantly higher than that in the control group (75.27% ± 0.55%, t = 10.49, p < 0.001), and the difference was statistically significant. Compared with the blank control group, the structure and morphology of pyramidal neurons in the prefrontal cortex and CA1 region of the hippocampal gyrus were similar, and their integrity was better. The structural integrity of granulosa neurons was destroyed and cell edema increased in the perfusion group compared with the blank control group. Immunofluorescence staining for glail fibrillary acidic protein and Iba1, markers of glial cells, revealed well-preserved cell structures in the perfusion group. While there were indications of abnormal cellular activity, the analysis showed no significant difference in axon thickness or integrity compared to the 1-h blank control group. CONCLUSIONS Mild hypothermic machine perfusion can improve ischemia and hypoxia injury of yorkshire brain tissue caused by traumatic blood loss and delay the necrosis and apoptosis of yorkshire brain tissue by continuous oxygen supply, maintaining ion homeostasis and reducing tissue metabolism level.
