OBJECTIVE To investigate the effects and mechanism of total alkaloids of Corydalis Rhizoma (TAC) on the regulation of cuproptosis in rats with diabetic cardiomyopathy (DCM) based on silence information regulator 1(Sirt1)/tumor protein 53(P53)signaling pathway. METHODS DCM rat model was induced by high-fat and high-sugar diet and intraperitoneal injection of streptozotocin. Thirty-two model rats were randomly divided into model group, TAC low-dose, medium-dose and high-dose groups (7, 10.5, 14 mg/kg), with 8 rats in each group. An additional 8 rats were assigned to normal control group. Related drugs or normal saline were administered intragastrically in each group, once a day, for 4 weeks. After the last medication, the fasting blood glucose (FBG) levels of the rats were measured. The levels of myocardial creatine kinase (CK), creatine kinase isoenzyme (CK-MB), and lactate dehydrogenase (LDH) in serum and myocardial tissue of rats were all detected. The pathological morphology, fibrosis degree, and Cu2+ deposition of myocardial tissue in rats were observed. The levels of Cu2+ and glutathione (GSH) in myocardial tissue, the expressions of Sirt1/P53 signaling pathway-related proteins [Sirt1, P53, solute carrier family 7 membrane 11 (SLC7A11)], and iron-sulfur cluster-related proteins [ferredoxin 1 (FDX1), lipoic acid synthetase (LIAS), aconitase 2 (ACO2), NADH-ubiquinone oxidoreductase core subunit S8 (NDUFS8), dihydrolipoamide acetyltransferase (DLAT), dihydrolipoamide succinyltransferase (DLST)], and heat shock protein 70 (HSP70) were all determined. RESULTS Compared with normal control group, the model group exhibited significantly elevated levels of FBG, CK, CK-MB and LDH in both serum and myocardial tissue, as well as increased 2+ levels of Cu in myocardial tissue and the expression of P53 and HSP70 proteins (P<0.05); the level of GSH and the expression levels of Sirt1, SLC7A11, FDX1, LIAS, ACO2, NDUFS8, DLAT, and DLST proteins in myocardial tissue were all significantly decreased (P<0.05); the myocardial tissue exhibited severe pathological damage, with numerous inflammatory cell infiltrations and significant fibrosis, as well as increased deposition of Cu2+. Compared with model group, most of the above quantitative indicators in rats were significantly reversed in TAC groups (P<0.05); the pathological damage to the myocardial tissue was alleviated, with reduced fibrosis and Cu2+ deposition. CONCLUSIONS TAC can ameliorate DCM in rats, and its mechanism of action may be related to activating the activity of the Sirt1/P53 signaling pathway, promoting the chelation of GSH with Cu2+, and inhibiting cuproptosis of cardiomyocyte.

OBJECTIVE To design and synthesize mono-carbonyl curcumin analogues(MCACs) and investigate the activities of them against breast cancer. METHODS The analogues F1, F2, and F3 were obtained by aldol condensation reaction, and their antitumor activities(including the activities of human breast cancer cell MCF-7 and human lung cancer cell A549) were detected by MTT assay [evaluated with half inhibitory concentration(IC50)]. The results of MTT assay were compared with those of curcumin. Bioinformatics methods were used to collect the core targets of analogues F1, F2 and F3 acting on breast cancer, and then molecular docking verification was carried out. The cell experiments were conducted to investigate the effects of high, medium and low concentrations (16, 8, 4 μmol/L) of F1, F2 and F3 on the expression of the first core target protein as well as the effects of medium concentration of F1, F2 and F3 on the expression of cleaved-caspase-3. RESULTS Compared with curcumin, IC50 of analogues F1, F2 and F3 to A549 and MCF-7 cells(except for IC50 of analogue F2 to A549 cells) were decreased significantly(P< 0.05 or P<0.01); among them, IC50 of analogue F2 to MCF-7 cell was the lowest, being(9.67±1.27) μmol/L. Bioinformatics analysis showed that index of affinity of analogues F1, F2 and F3 with the first core target epidermal growth factor receptor (EGFR), protein kinase B (AKT) and AKT were 5.909 2, 8.402 5 and 6.486 6, respectively; high concentration of F1 could significantly reduce the phosphorylation level of EGFR protein in MCF-7 cells(P<0.01), while low, medium, and high concentrations of F2 and high concentration of F3 could significantly reduce the phosphorylation level of AKT protein in MCF-7 cells(P<0.05 or P<0.01). Medium concentration of F1, F2, and F3 could significantly increase the expression level of cleaved- caspase-3 protein in MCF-7 cells(P<0.01). CONCLUSIONS Designed and synthesized MCACs F1, F2 and F3 all have good anti- breast cancer activity, and F2 has better anti-breast cancer activity.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Purpose:
It was aimed to clarify the casual connection between prostate cancer (PCa) and arthritis by utilizing two-sample Mendelian randomization (MR) analysis and data from National Health and Nutrition Examination Survey (NHANES) database.
Materials and Methods:
This study utilized NHANES data. Through association analysis and risk stratification analysis, the association between arthritis and PCa were examined. MR analysis was performed to elucidate the causal relationship between arthritis and PCa. Sensitivity analysis and Steiger directionality test confirmed the reliability of the MR analysis results.
Results:
A total of 23,608 (PCa:controls=413:23,195) participants after a sample exclusion and variable definition process were screened in NHANES database. Adjustments across three diverse models consistently revealed a notable influence of arthritis on PCa progression. Arthritis was identified as a risk factor for PCa (odds ratio [OR] 1.88, 95% confidence interval [CI] 1.36–2.62, p<0.001). Subsequent analysis indicated that in the arthritis-adjusted model with multiple covariates, the area under the curve of the receiver operating characteristic curve was 0.94. The inverse variance weighting method of MR analysis showed a causal relationship between rheumatoid arthritis (RA) and PCa (OR 1.090, 95% CI 1.053–1.128, p<0.001) as well as osteoar-thritis and PCa (OR 1.002, 95% CI 1.001–1.004, p=0.002). This suggested that RA and osteoarthritis were risk factors for PCa. The heterogeneity (p>0.05), horizontal pleiotropy (p>0.05), leave-one-out and Steiger test confirmed reliability of MR results.
Conclusions
NHANES database and MR analyses identified arthritis as a risk factor for PCa, offering fresh avenues for preventive and therapeutic approaches.

ObjectiveTo obtain the gene sequences of major histocompatibility complex (MHC ) Ⅱgenes of Wuzhishan pigs, analyze their genetic information, and explore the biological functions of their MHC system. MethodsSpleen samples were collected from 3 adult male Wuzhishan pigs. Primers were designed according to MHCⅡ gene sequences, and the coding sequences of Wuzhishan pig MHCⅡ genes were amplified by RT-PCR. Sanger sequencing was performed to determine the full-length sequences. Bioinformatics tools were employed to analyze the physicochemical properties, phylogenetic relationships, conserved motifs, structural domains, chromosomal localization, and syntenic relationships of these genes. ResultsEight MHCⅡ genes were identified in Wuzhishan pigs, designated as SLA-DRA, SLA-DQA, SLA-DQB, SLA-DRB, SLA-DOB, SLA-DMB, SLA-DMA and SLA-DOA. The full-length sequences of these genes were determined by Sanger sequencing and subsequently deposited in GenBank under accession numbers PQ182796, PQ182797, PQ182798, PQ182799, PQ182800, PQ182801, PQ182802, and PQ164779. Phylogenetic analysis showed that the six MHCⅡ genes of Wuzhishan pigs clustered separately from their counterparts in Duroc, Meishan, Large White, and Bama pigs, indicating distinct evolutionary trajectories. Bioinformatics analysis demonstrated that most MHC Ⅱ proteins were hydrophobic, with molecular weights ranging from 27 700 to 30 000 Da. Genes within the same subregion shared conserved motifs. Specifically, four MHCⅡ proteins encoded by SLA-DQB, SLA-DRB, SLA-DOB, and SLA-DMB contained the MHCⅡβ conserved domain, while those encoded by the genes SLA-DRA, SLA-DQA, SLA-DMA, and SLA-DOA contained the MHCⅡα conserved domain. The eight MHCⅡ genes were scattered along the long arm of chromosome 7 in the Wuzhishan pigs, exhibiting syntenic relationships with three human genes and five Duroc pig genes. ConclusionThe MHCⅡ genes of Wuzhishan pigs may possess a unique evolutionary origin.

Objective To investigate the factors associated with unplanned readmission within 30 days after discharge in adult patients who underwent coronary artery bypass grafting (CABG) and to develop and validate a risk prediction model. Methods A retrospective analysis was conducted on the clinical data of patients who underwent isolated CABG at the Nanjing First Hospital between January 2020 and June 2024. Data from January 2020 to August 2023 were used as a training set, and data from September 2023 to June 2024 were used as a validation set. In the training set, patients were divided into a readmission group and a non-readmission group based on whether they had unplanned readmission within 30 days post-discharge. Clinical data between the two groups were compared, and logistic regression was performed to identify independent risk factors for unplanned readmission. A risk prediction model and a nomogram were constructed, and internal validation was performed to assess the model’s performance. The validation set was used for validation. Results A total of 2 460 patients were included, comprising 1 787 males and 673 females, with a median age of 70 (34, 89) years. The training set included 1 932 patients, and the validation set included 528 patients. In the training set, there were statistically significant differences between the readmission group (79 patients) and the non-readmission group (1 853 patients) in terms of gender, age, carotid artery stenosis, history of myocardial infarction, preoperative anemia, and heart failure classification (P<0.05). The main causes of readmission were poor wound healing, postoperative pulmonary infections, and new-onset atrial fibrillation. Multivariable logistic regression analysis revealed that females [OR=1.659, 95%CI (1.022, 2.692), P=0.041], age [OR=1.042, 95%CI (1.011, 1.075), P=0.008], carotid artery stenosis [OR=1.680, 95%CI (1.130, 2.496), P=0.010], duration of first ICU stay [OR=1.359, 95%CI (1.195, 1.545), P<0.001], and the second ICU admission [OR=4.142, 95%CI (1.507, 11.383), P=0.006] were independent risk factors for unplanned readmission. In the internal validation, the area under the curve (AUC) was 0.806, and the net benefit rate of the clinical decision curve analysis (DCA) was >3%. In the validation set, the AUC was 0.732, and the DCA net benefit rate ranged from 3% to 48%. Conclusion Females, age, carotid artery stenosis, duration of first ICU stay, and second ICU admission are independent risk factors for unplanned readmission within 30 days after isolated CABG. The constructed nomogram demonstrates good predictive power.
