Aim To investigate the effect of oroxylin A(OA)on apoptosis in Ishikawa cell line of endometrial cancer and the underlying mechanism through the phosphatidylinositol-3 kinase/protein kinase B(PI3K/AKT)signaling pathway.Methods Ishikawa cells were treated with different concentrations of OA(0,4,8,10,12,and 20 μmol·L-1)for 24 h-72 h,the cell viability was detected by CCK-8 assay,apoptosis was detected by flow cytometry,and the protein ex-pression levels of B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),PI3K/AKT,recombinant cytochrome P450 1B1(CYP1B1),and catechol-O-methyltransferase(COMT)were detected by Western blot technique.Results OA inhibited the prolifera-tion of Ishikawa cells in a concentration-and time-de-pendent manner.Compared with the blank control group,the expression of Bax protein increased signifi-cantly,while the expression of Bcl-2 protein decreased significantly with the increase of OA concentration.The expression of COMT protein increased significant-ly,while the expression of CYP1B1 protein decreased significantly.PI3K/AKT:IGF-1(PI3 K agonist)sup-plementation reversed the effect,the expression of COMT protein significantly decreased,and the expres-sion of CYP1B1 protein significantly increased.Con-clusions OA exerts anti-tumor effects in Ishikawa cells of endometrial cancer,which may be related to cell apoptosis mediated by the inhibition of the PI3K/AKT signaling pathway.

AIM To investigate the impact of varying dosages of Supplemented Wendan Decoction on the PI3K/Akt/FOXO1 glycolipid metabolic pathway in 3T3-L1 adipocytes.METHODS The CCK-8 assay was used to determine the concentration of Supplemented Wendan Decoction-medicated serum.The mature adipocytes differentiated from 3T3-L1 preadipocytes after induction were further divided into the blank control group,the model group,the rosiglitazone group(10 mg/L),and the Supplemented Wendan Decoction groups(5％,10％,and 20％),followed by the sample collections after 48 hours of treatment.Oil red O staining quantified lipid accumulation in 3T3-L1 adipocytes;extracellular glucose levels were measured using glucose oxidase(GOD)assay;RT-qPCR analyzed mRNA expressions of IRS-1,PI3K,Akt,GLUT4,IL-6,TNF-α and IL-1β;Western blot assessed protein expressions of INSR,IRS-1,PI3K-p85,Akt,FOXO1 and GLUT4.RESULTS No significant changes in cell viability(P＞0.05)were observed in 3T3-L1 preadipocytes exposed to serum containing supplemented Wendan Decoction at different concentrations for 24,48,or 72 hours.The 3T3-L1 preadipocytes held the capacity to differentiate into mature adipocytes within a 14-day induction period.Compared to the model group,all supplemented Wendan Decoction groups exhibited reduced lipid accumulation in adipocytes and downregulated mRNA expression of IRS-1,IL-6,TNF-α and IL-1β(P＜0.01);the low-dose group demonstrated increased mRNA expressions of PI3K and GLUT4(P＜0.05,P＜0.01),alongside elevated protein expressions of INSR,IRS-1,PI3K-p85,Akt and GLUT4(P＜0.05,P＜0.01);the medium-dose group showed enhanced GLUT4 mRNA expression,and upregulated protein expressions of INSR and FOXO1(P＜0.01).After 24 hours intervention,the high-dose Supplemented Wendan Decoction group exhibited increased glucose consumption in adipocytes(P＜0.01),and elevated protein expression of INSR,Akt and FOXO1(P＜0.05,P＜0.01).CONCLUSION Supplemented Wendan Decoction reduces lipid accumulation in adipocytes,regulates glucose and lipid metabolism,and promotes metabolic homeostasis through PI3K/Akt/FOXO1 signaling pathway.

Objective:To investigate the association of serum levels of myoglobin(Myo)and reticulocyte(Ret)with cardiac function class in patients with chronic heart failure(CHF).Methods:A total of 106 CHF patients treated in First Rongjun Special Care Hospital of Hebei Province between February 2020 and February 2024 were retrospec-tively selected as the observation group.According to New York Heart Association(NYHA)cardiac function class,patients were divided into class Ⅱ group(n=61)and class Ⅲ～Ⅳ group(n=45),and 107 healthy people with nor-mal physical examination results were selected from our hospital simultaneously as control group.The Myo and Ret levels were compared between control group and observation group,class Ⅱ group and class Ⅲ～Ⅳ group.Spearman correlation analysis was used to analyze the association of Myo and Ret levels with NYHA class in CHF patients.Receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of Myo,Ret and their combined detection for NYHA class Ⅲ～Ⅳ in CHF patients.Results:Compared to participants in the control group,those in the observation group had significant higher Myo level[(50.42±9.98)μg/ml vs.(35.22±5.36)μg/ml]and significant lower Ret level[(2.24±0.68)％vs.(2.91±0.61)％](P＜0.001 all).Compared to those in class Ⅱ group,those in class Ⅲ～Ⅳ group had significant higher Myo level[(60.77±5.94)μg/ml vs.(42.79±2.97)μg/ml]and significant lower Ret level[(1.73±0.31)％vs.(2.62±0.62)％](P＜0.001 all).Spearman correlation analysis showed that Myo(r=0.654)was positively correlated with NYHA cardiac function class in CHF patients,while Ret(r=-0.589)was inversely correlated with it(P＜0.001 all).ROC analysis showed that a combination of Myo and Ret had significant higher predictive efficacy(AUC=0.926,95％CI 0.858～0.968)for NYH A class Ⅲ～Ⅳ in CHF patients than Myo(AUC=0.804,95％CI 0.716～0.875)and Ret(AUC=0.701,95％CI 0.604～0.786)alone(Z=2.745,4.183,P＜0.01 both).Conclusion:Our study showed that Myo and Ret levels were significantly correlated with NYHA class in CHF patients.Moreover,a combination of Myo and Ret levels showed better diagnostic value for NYHA class Ⅲ～Ⅳ in this population.

As artificial intelligence technology rapidly advances, its deployment within the medical sector presents substantial ethical challenges. Consequently, it becomes crucial to create a standardized, transparent, and secure framework for processing medical data. This includes setting the ethical boundaries for medical artificial intelligence and safeguarding both patient rights and data integrity. This consensus governs every facet of medical data handling through artificial intelligence, encompassing data gathering, processing, storage, transmission, utilization, and sharing. Its purpose is to ensure the management of medical data adheres to ethical standards and legal requirements, while safeguarding patient privacy and data security. Concurrently, the principles of compliance with the law, patient privacy respect, patient interest protection, and safety and reliability are underscored. Key issues such as informed consent, data usage, intellectual property protection, conflict of interest, and benefit sharing are examined in depth. The enactment of this expert consensus is intended to foster the profound integration and sustainable advancement of artificial intelligence within the medical domain, while simultaneously ensuring that artificial intelligence adheres strictly to the relevant ethical norms and legal frameworks during the processing of medical data.
