Background Liver cancer is one of the common malignant tumors. Phthalates (PAEs), as a widely used class of plasticizers, can participate in the occurrence and progression of liver diseases through multiple pathways. Objective To explore the association between PAEs exposure and liver cancer risk and to provide a scientific basis for the prevention of environment-related tumor risk events. Methods Chi-square test and logistic regression were employed to analyze data from the National Health and Nutrition Examination Survey (NHANES) database between 2001 and 2018, to investigate the association between PAEs exposure and liver cancer. Network toxicology combined with machine learning was used to screen independent prognostic genes associated with PAEs and liver cancer, and to evaluate their correlations with tumor immunity, tumor pathway activation, and tumor drug resistance. Finally, the prediction results were validated using GEO datasets, molecular docking, and molecular dynamics simulations. Results After screening,

ObjectiveTo explore the effect of blood flow restriction training (BFRT) under different intensities combined with low-intensity resistance training (LIRT) on motor function in stroke patients with frailty. MethodsFrom August, 2024 to August, 2025, 200 elderly ischemic stroke patients with frailty from Affiliated Hospital, North China University of Science and Technology were randomized into control group and observation groups 1, 2 and 3, with 50 cases in each group. All the groups received 30% 1RM resistance training. In addition, the observation groups received BFRT of 40%, 50% and 60% arterial occlusion pressure (AOP), respectively. Before training, and four and eight weeks after training, their motor function was evaluated with Fugl-Meyer Assessment-Upper Extremities (FMA-UE) and Fugl-Meyer Assessment-Lower Extremities (FMA-LE), grip strength, 10-Metre Walk Test (10MWT) and Berg Balance Scale (BBS); Fried Frailty Phenotype (FFP) was used to assess frailty status; and the score of modified Ashworth Scale (MAS), blood pressure and resting heart rate were recorded. ResultsOne case dropped out in each group. For the scores of FMA-UE and FMA-LE, the grip strength of both hands, the time of 10MWT and the score of BBS, the main effects of group and time, and interaction effect were all significant (F > 2.745, P < 0.05); four weeks after training, the above indexes were better in the observation groups than in the control group (P < 0.05); eight weeks after training, the scores of FMA-UE and FMA-LE, the grip strength of both hand and the score of BBS were better in the observation group 3 than in the observation groups 1 and 2 (P < 0.05), and the time of 10MWT was better in the observation group 3 than in the observation group 1 (P < 0.05). For the score of FFP, the main effect of group was significant (F = 688.360, P < 0.001), however, the effects of time and interaction were not significant (P > 0.05). For the score of MAS, the main effect of group was significant (F = 7.171, P = 0.008), however, the effects of time and interaction were not significant (P > 0.05). For the blood pressure and resting heart rate, the main effects of group and time, and interaction effect were not significant (P > 0.05). ConclusionBFRT under different intensities combined with LIRT can safely improve the motor function, grip strength, walking ability in elderly stroke patients, and 60% AOP may be more effective.

Chronic atrophic gastritis (CAG), a common digestive system disease, has an unclear pathogenesis. Currently, it is mostly believed to be related to Helicobacter pylori (Hp) infection, immune factors, dietary factors, bile reflux, long-term use of antibiotics and anti-inflammatory drugs, and other factors. Ferroptosis is a regulated cell death mechanism that is iron-dependent and characterized by disruption of iron metabolism and accumulation of lipid peroxides. More and more studies have found that ferroptosis is closely related to the onset of CAG. Professor LI Diangui, a master of traditional Chinese medicine, first proposed the turbid toxin theory, which holds that spleen deficiency and turbid toxin is the main pathogenic mechanism of CAG. Abnormal iron metabolism regulation is a prerequisite for the accumulation of turbid toxin in CAG, and ferroptosis is in accordance with the pathogenic mechanism (spleen deficiency and turbid toxin) of CAG. This article explores the pathological mechanism of spleen deficiency and turbid toxin in CAG from the perspectives of iron metabolism, oxidative stress, and lipid peroxidation, providing theoretical support of traditional Chinese medicine for the modern research on CAG. It enriches the modern scientific connotation of the turbid toxicity theory and provides new ideas and breakthrough points for the clinical treatment of CAG.

The neonatal mammalian heart has a remarkable regenerative capacity, while the adult heart has difficulty to regenerate. A metabolic reprogramming from glycolysis to fatty acid oxidation occurs along with the loss of cardiomyocyte proliferative capacity shortly after birth. In this study, we sought to determine if and how metabolic reprogramming regulates cardiomyocyte proliferation. Reversing metabolic reprogramming by carnitine palmitoyltransferase 1 (CPT1) inhibition, using cardiac-specific Cpt1a and Cpt1b knockout mice promoted cardiomyocyte proliferation and improved cardiac function post-myocardial infarction. The inhibition of CPT1 is of pharmacological significance because those protective effects were replicated by etomoxir, a CPT1 inhibitor. CPT1 inhibition, by decreasing poly(ADP-ribose) polymerase 1 expression, reduced ADP-ribosylation of dual-specificity phosphatase 1 in cardiomyocytes, leading to decreased p38 MAPK phosphorylation, and stimulation of cardiomyocyte proliferation. Our present study indicates that reversing metabolic reprogramming is an effective strategy to stimulate adult cardiomyocyte proliferation. CPT1 is a potential therapeutic target for promoting heart regeneration and myocardial infarction treatment.

The active ingredients of Curcuma aromatica have multi-target effects and could intervene in the process of neurodegenerative diseases from multiple perspectives, such as promoting the clearance of Aβ, anti-inflammatory, anti-oxidant, neuroprotective, anti-depressant, and anti-tumor effects. However, the low bioavailability of Curcuma extracts limits their therapeutic effects in the body. In addition, the side effects of long-term use and the dose-effect relationship are still unclear, and more new pharmacodynamic observations are needed. This article reviews the research on single-ingredient and compound traditional Chinese medicine preparations of Curcuma to provide references for clinical medication.

Objective:To investigate the association of serum/body fluid heparin-binding protein (HBP) and blood lactate levels with disease severity and their impact on prognosis in intensive care unit (ICU) patients with sepsis.Methods:Clinical data from 100 sepsis patients admitted to Ma'anshan Shiqiye Hospital ICU (January 2023-September 2024) were retrospectively analyzed. According to Sepsis-3.0 criteria, patients were divided into: uncomplicated sepsis (general group, n=28), sepsis with organ failure/hypotension (severe group, n=61), and septic shock (shock group, n=11). Comparisons included serum/body fluid HBP, lactate, APACHE Ⅱ scores, and mortality across severity groups and laboratory parameters between survivors and non-survivors. Logistic regression was used to identify prognostic predictors. Non-normally distributed data were presented as M(Q1,Q3), comparison between groups were completed by Kruskal-Wallis H test and Mann-Whitney U tests. Spearman correlation was used to analyze relationships between biomarkers and APACHE Ⅱ scores. Categorical data were presented as n(%), and comparison between groups were completed by χ2 test or Fisher's exact tests. ROC curves was used to evaluate predictive value. Results:Shock group demonstrated significantly higher serum HBP [13.3 (12.6-16.4) μg/L], infection-site HBP [230.3 (226.3-241.1) μg/L], lactate [5.4 (4.9-5.6) mmol/L], and APACHE Ⅱ[22.0 (21.0-24.0)] than severe group [9.6 (8.9-10.5) μg/L; 208.9 (200.5-216.1) μg/L; 2.7 (2.6-2.8) mmol/L; 18.0 (17.0-19.0)] and general group [7.4 (6.3-8.1) μg/L; 190.6 (180.5-202.1) μg/L; 1.5 (1.4-1.7) mmol/L; 13.0 (12.0-14.0)] (all P<0.001). There was statistically significant difference in the mortality rate during hospita lization among three groups of patients ( χ2=30.49, P<0.001). Mortality was higher in shock group than severe group than general group [72.7% (8/11) vs. 11.5% (7/61) vs. 3.6% (1/28), all P<0.001]. Non-survivors exhibited elevated lactate [4.8 (2.7-5.5) vs. 2.6 (1.7-2.8) mmol/L, Z=-4.13, P=0.001], serum HBP [12.2 (9.2-13.3) vs. 9.3 (7.8-10.4) μg/L, Z=-3.12, P=0.002], and infection-site HBP [226.8 (209.9-237.6) vs. 203.6 (194.0-212.8) μg/L, Z=-4.32, P<0.001] vs. survivors. Serum HBP ( r=0.74), infection-site HBP ( r=0.64), and lactate ( r=0.86) were all positively correlated with APACHE Ⅱ (all P<0.001). After adjusting for age and APACHE Ⅱ, elevated serum HBP ( OR=3.743, 95% CI:1.834-7.640), infection-site HBP ( OR=3.540, 95% CI:1.932-6.486), and lactate ( OR=5.155, 95% CI:1.868-14.229) independently predicted mortality (all P<0.001). Combined biomarker detection showed superior predictive value (AUC=0.909) versus individual markers (serum HBP:0.747, infection-site HBP:0.842, lactate:0.827, all P<0.001). Conclusion:Elevated blood lactate and serum/infection-site HBP levels correlate with sepsis severity and independently predict mortality. The biomarker combination provides optimal prognostic stratification.
