    Objective

    To investigate the potential mechanisms and related signaling pathways of mitophagy in the occurrence and development of autosomal dominant polycystic kidney disease (ADPKD) using bioinformatics techniques.

    Methods

    The gene expression omnibus (GEO) dataset GSE7869 was downloaded and processed. Differentially expressed genes (DEGs) were identified using the R limma package. Mitophagy-related genes were retrieved from the GeneCards database and intersected with the DEGs to obtain candidate genes. A protein-protein interaction (PPI) network was constructed using STRING, and core genes were identified in Cytoscape using the maximalclique centrality (MCC) algorithm. Gene set enrichment analysis (GSEA) was conducted based on albumin (ALB) expression levels, and R packages including clusterProfiler, ggplot2 and enrichplot were used to visualize and interpret the enrichment results.

    Results

    A total of 248 DEGs were obtained, including 61 up-regulated and 187 down-regulated genes. After intersecting with mitophagy-related genes, 38 candidate DEGs were identified. ALB was identified as the core differentially expressed gene through PPI analysis and Cytoscape. GSEA results indicated that the mitophagy-related gene ALB may play a role in ADPKD by regulating pathways such as extracellular matrix (ECM)-receptor interaction and branched-chain amino acid (BCAA) metabolism, as well as biological processes including organic acid and amino acid metabolism and organization of collagen fibrils.

    Conclusions

    ALB expression levels were significantly associated with pathways including ECM-receptor interaction and branched-chain amino acid metabolism, as well as with biological processes such as organic acid and amino acid metabolism and organization of collagen fibrils. These findings suggest that ALB may be involved in the pathogenesis of ADPKD.

    Objective

    To investigate the preventive and therapeutic effects of Tanshinone ⅡA on radiation-induced heart disease (RIHD) through the regulation of the phosphoinositide 3-kinase/AKT/mechanistic target of rapamycin (PI3K/AKT/mTOR) signaling pathway, and to elucidate its underlying mechanisms based on animal and cellular experiments, thereby providing a theoretical foundation for developing targeted clinical prevention and treatment strategies.

    Methods

    In animal experiments, SPF-grade rats and mice were respectively divided into blank control group, model group and experimental group. A single dose of X-ray irradiation (25 Gy for rats, 20 Gy for mice) was administered to establish the RIHD model. The blank control group received normal feeding. The model group received normal feeding after modeling. The experimental group received daily intraperitoneal injections of Tanshinone ⅡA sulfonate sodium injection (1 mg/10 g body weight) for one week following modeling. In cell experiments, H9C2 cardiomyocytes were divided into normal cell group, injury-induced group and a drug-treated group. A radiation-induced RIHD cell model was established. The normal cell group was cultured under standard conditions. The injury-induced group was cultured normally after modeling. The drug-treated group was administered Tanshinone ⅡA sulfonate sodium (1μL·mL-1 culture medium) immediately after modeling. Body weight changes and myocardial histopathological characteristics were dynamically monitored. Transcriptome sequencing was performed on cardiac apex tissues from both rats and mice for joint analysis, aiming to screen for common differentially expressed genes and enriched pathways. Cell viability was assessed using the cell counting kit-8 (CCK-8) assay. Cell membrane damage was evaluated by the lactate dehydrogenase (LDH) release assay. The expression levels of key genes in PI3K/AKT/mTOR pathway, including angiopoietin-2 (ANGPT2) and cyclin D1 (CCND1), as well as the protein levels of phosphorylated phosphoinositide 3-kinase (P-PI3K) and phosphorylated AKT serine/threonine kinase (P-AKT) were detected using real-time quantitative polymerase chain reaction (RT-qPCR) and Western blotting, respectively.

    Results

    Animal experiments showed that after the intervention, the body weights of rats in the blank control group, model group and experimental group were (434.37±8.52), (341.61±8.73) and (410.13±10.05) g, respectively; the body weights of mice were (30.97±0.89), (26.24±0.86) and (30.96±0.87) g, respectively; AST levels were (159.92±3.83), (171.04±2.63) and (149.63±10.55) U·L-1, respectively; CK-MB levels were (219.00±5.83),(455.42±32.76) and (248.36±15.25) U·L-1, respectively; LDH levels were (677.20±21.22),(864.63±6.39) and (635.77±22.72) U·L-1, respectively; BNP levels were (29.37±6.04),(241.69±12.75) and (134.23±13.57) pg·mL-1, respectively; GSH levels were (160.73±4.65), (330.38±9.41) and (116.71±11.29) U·L-1, respectively. All the aforementioned indicators in model group showed statistically significant differences compared to blank control group, and all indicators in the experimental group showed statistically significant differences compared to model group (all P<0.001). In the cell experiments, joint transcriptome analysis revealed that 72% of homologous differentially expressed genes (624 in rats, 341 in mice) exhibited consistent expression trends in both species. Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis indicated that ANGPT2, CCND1, THBS1, COL4A1, FN1 and COL4A2 were primarily enriched in the PI3K/AKT/mTOR pathway (all P<0.05), and PCR validation confirmed this consistent trend. In vitro experiments confirmed that the cell viabilities in normal cell group, injury-induced group and drug-treated group were (118.40±8.63)%, (73.10±6.12)% and (91.57±8.08)%, respectively. The differences between injury-induced group and normal cell group, as well as between drug-treated group and injury-induced group, were statistically significant (both P<0.001). The LDH release levels in injury-induced group and drug-treated group were (1.03±0.02) and (0.77±0.01)-fold that of normal cell group, respectively. The difference between the drug-treated group and the injury-induced group was statistically significant (P<0.001). The relative expression levels of P-PI3K in normal cell group, injury-induced group and drug-treated group were 0.92±0, 0.76±0.01 and 0.85±0.02, respectively; the relative expression levels of P-AKT were 0.79±0.01, 0.70±0.01 and 0.76±0.01, respectively. The differences between the injury-induced group and the normal cell group, as well as between the drug-treated group and the injury-induced group were statistically significant (all P<0.05).

    Conclusion

    Tanshinone ⅡA mitigates radiation-induced cardiac injury by activating the PI3K/AKT/mTOR signaling pathway, upregulating key phosphorylated proteins (p-PI3K and p-AKT), reducing radiation toxicity and enhancing cellular viability.

    With the advancement of artificial intelligence, the European Medicines Agency released " Guiding principles on the use of large language models in regulatory science and for medicines regulatory activities" in 2024, emphasizing the importance of the safe and responsible use of large language models. This guidance covers general ethical considerations, user principles and organizational principles, clearly outlining the potential of large language models in areas such as text processing assistance and data mining, while also warning of risks such as hallucinations, data privacy issues, and biased outputs. It proposes measures including continuous learning, risk monitoring and mechanism-building to address these challenges. Although China has not yet issued similar guidelines, large language models hold potential application prospects in areas such as assisting in the processing of review materials, formulating and revising guidance principles and identifying risks. At the same time, challenges related to decision interpretability, data bias, legal accountability and talent reserves remain. It is recommended that China’s regulatory authorities draw on international experience to construct an application framework tailored to national conditions as soon as possible, thereby promoting the integration of artificial intelligence technology with the field of drug regulation.

    Objective

    To observe the clinical efficacy and safety of remimazolam injection combined with fentanyl injection in the induction of general anesthesia for pediatric laparoscopic hernia surgery.

    Methods

    The children who underwent elective laparoscopic hernia surgery in our hospital were divided into successful sedation group and failed sedation group according to whether laryngeal mask placement was completed under sedation remedy. Remimazolam injection was administered intravenously, using an initial dose of 0.3 mg·kg-1 with a dose increment of 0.05 mg·kg-1. The dose for the next patient was determined according to the modified Dixon sequential method. Patients who successfully underwent laryngeal mask insertion were included in the sedation success group, while those requiring additional intravenous propofol for sedation to complete laryngeal mask insertion were included in the sedation failure group. Remimazolam injection combined with fentanyl injection was calculated by modified Probit regression for the induction of half effective dose (ED50) and 95% effective dose (ED95) and its 95% confidence interval (CI) in pediatric laparoscopic hernia induction of general anesthesia. Recorded vital signs during anesthesia induction, preoperative, dosage and intraoperative procedures, and evaluated for safety.

    Objective

    To evaluate the effects of dapagliflozin tablets on metabolic and cardiovascular system in patients with chronic kidney disease (CKD).

    Methods

    CKD patients hospitalized in our institution who underwent coronary computed tomography angiography (CCTA) were divided into dapagliflozin group and non-dapagliflozin group according to treatment regimens. Levels of uric acid, creatinine, uric acid reduction rate, creatinine reduction rate and coronary artery calcium score (CACS) were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to assess the independent risk factors of dapagliflozin on coronary artery calcification (CAC).

    Results

    A total of 30 cases were included in dapagliflozin group, 60 cases were included in non-dapagliflozin group. After treatment, uric acid levels were (182.31±52.56) and (221.75±73.45) μmol·L-1, creatinine levels were (49.27±15.33) and (55.20±16.43) μmol·L-1, CACS were 0 (0, 0) and 0 (0, 28.93) points, uric acid reduction rates were (46.34±7.45)% and (25.81±4.56)%, creatinine reduction rates were (27.23±5.53)% and (9.12±2.46)%, and CAC incidence rates were 3.33% and 20.00% in the dapagliflozin group and non-dapagliflozin group, respectively. All the above indicators showed statistically significant differences between the two groups (all P<0.05). Multivariate logistic regression analysis showed that, after adjusting for confounding factors including sex, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), uric acid, total cholesterol, low-density lipoprotein cholesterol (LDL-C) and glycated hemoglobin (HbA1c), dapagliflozin remained an independent protective factor against CAC (OR=0.128, 95% CI: 0.03-0.62, P<0.05). The main adverse drug reactions of dapagliflozin group were mild genitourinary infection and postural hypotension; hypoglycemia and urinary tract infection were the main adverse drug reaction in non-dapagliflozin group. The total incidence of adverse drug reactions in dapagliflozin group and non-dapagliflozin group were 10.00% and 6.67%, respectively, with no significant difference in statistics (P>0.05), demonstrating good safety profile.

    Conclusion

    Dapagliflozin tablets can significantly reduce uric acid, creatinine and CACS levels in CKD patients, and may serve as a potential protective factor against coronary artery calcification.

    The cell viability rates of the control group, model group and experimental group were (100.00±2.84)%, (64.91±9.57)% and (81.36±13.19)%, respectively; the relative expression levels of CCDC92 mRNA in the control group, model group, experimental group, AAV-NC group and AAV-CCDC92 group were 1.00±0.12, 2.26±0.35, 1.42±0.19, 1.48±0.22 and 2.05±0.34, respectively; the number of invasive cells were (79.35±11.62), (25.81±4.06), (53.69±7.95), (60.46±10.58) and (41.13±7.27) cells, respectively; the relative expression levels of Nephrin protein were 1.00±0.14, 0.31±0.05, 0.65±0.09, 0.58±0.08 and 0.39±0.06, respectively; the relative expression levels of Podocin protein were 1.00±0.17, 0.28±0.04, 0.61±0.11, 0.56±0.09 and 0.32±0.06, respectively; the relative expression levels of LC3Ⅱ/Ⅰ protein were 1.00±0.17, 0.26±0.04, 0.74±0.12, 0.69±0.11 and 0.41±0.08, respectively; the relative expression levels of Beclin1 protein were 1.00±0.15, 0.32±0.06, 0.68±0.10, 0.75±0.12 and 0.46±0.07, respectively; the relative expression levels of phosphorylated (p)-AMPK/AMPK protein were 1.00±0.19, 0.23±0.04, 0.86±0.17, 0.89±0.16 and 0.38±0.07, respectively; the relative expression levels of p-mTOR/mTOR protein were 1.00±0.16, 3.16±0.53, 1.72±0.31, 1.65±0.29 and 2.91±0.52, respectively. There were statistically significant differences in the above indicators between the model group and the control group, between the experimental group and the model group and between the AAV-CCDC92 group and the AAV-NC group (P<0.05, P<0.01, P<0.001).

    Conclusion

    Equol can alleviate podocyte injury in DN through CCDC92, and the effects may be related to regulating the AMPK/mTOR pathway and improving autophagy level.
