Purpose:
The aim of this study is to determine the impact of solute carrier family 3 member 2 (SLC3A2) on the malignant phenotype of gliomas and its role in regulating ferroptosis sensitivity.
Materials and Methods:
The malignant phenotype of glioma was assessed by cell proliferation assay, colony formation assay, EdU assay, wound healing, and Transwell experiments. We further validated the impact of reduced SLC3A2 expression on the sensitivity to ferroptosis in glioma cells through Cell Counting Kit-8 assays, flow cytometry, western blotting, and transmission electron microscopy. Western blot was used to explore how SLC3A2 affects glioma sensitivity to ferroptosis through the AKT/NF-E2-related factor 2 (NRF2)/glutathione peroxidase 4 (GPX4) axis. By establishing a subcutaneous xenograft tumor model in BALB/c-nude mice, we investigated the growth of tumors following the knockout of SLC3A2 in glioma cells.
Results:
Downregulation of SLC3A2 suppressed the malignant phenotype of glioma by blocking the cell cycle and epithelial-mesenchymal transition processes. On the other hand, loss of SLC3A2 not only downregulated SLC7A11 but also prevented the activation of the AKT/NRF2/GPX4 axis. These lead to increased accumulation of reactive oxygen species and lipid peroxides, ultimately enhancing the susceptibility of glioma to ferroptosis.
Conclusion
Our findings suggest that SLC3A2 is an oncogene in gliomas, promoting their occurrence and development. It plays a critical role in ferroptosis resistance through the AKT/NRF2/GPX4 axis.

Energy metabolism disorders are a critical factor contributing to cognitive dysfunction.Astrocytes,as key suppliers of energy substrates to neurons,help to sustain normal cognitive function via their extensive energy metabolism activities in the brain,coordinated by various energy supply mechanisms.Imbalances in astrocyte-neuron energy metabolism coupling lead to abnormal neuronal activity,thereby driving the pathogenesis and progression of Alzheimer's disease(AD).It is therefore essential to investigate the pathological mechanisms and therapeutic targets associated with AD from the perspective of energy metabolism to support the future development of AD treatments and interventions.Traditional Chinese medicine(TCM),characterized by multi-component and multi-target effects,has shown potential efficacy for regulating cerebral energy metabolism,suggesting that modulating brain energy metabolism may represent a significant pathway by which TCM might ameliorate AD.This review systematically elucidates the mechanistic role of the dysregulation of astrocyte-neuron bioenergetic coupling in the pathogenesis and progression of AD,and critically evaluates recent advancements in therapeutic interventions mediated by TCM.

Objective:To explore the feasibility of high-level deep learning image reconstruction (DLIR-H) algorithm in dynamic myocardial perfusion (CTP) and coronary CT angiography (CCTA) extraction.Methods:From October 2021 to October 2022, 41 patients with confirmed or suspected coronary heart disease who underwent traditional CCTA and dynamic CTP examinations on GE Apex CT were prospectively collected. Traditional CCTA used 100 kVp tube voltage scan and DLIR-H to reconstruct the original image, while dynamic CTP used 80 kVp tube voltage scan to reconstruct the original image with ASiR-V 100% and DLIR-H, respectively. Comparing subjective and objective scores and myocardial blood flow (MBF) values?of rest and stress CTP between ASiR-V100% and DLIR-H. Subjective and objective scores, as well as stenosis degree and coronary CT blood flow reserve fraction (CT-FFR) value were analyzed on a vessel basis, and the image quality and diagnostic performance of traditional CCTA and single-phase CCTA (SP-CCTA) extracted under DLIR-H CTP were compared. Statistical analysis were performed using paired t test, Wilcoxon signed-rank test and χ2 test. Results:In the subjective image quality analysis of resting and stress CTP, DLIR-H was improved compared with ASiR-V100%, and the difference was statistically significant (all P<0.05). There was no significant difference in MBF values obtained by the two reconstruction methods in the assessment of quantitative myocardial perfusion ( P>0.05). Compared with traditional CCTA, the vascular CT value of SP-CCTA increased by 15.12%, the noise value increased by 32.27%, and the subjective score was also slightly lower (4.23±0.05). However, there were no statistically significant differences in total plaque volume, maximum stenosis degree, and number of CT-FFR positive vessels between SP-CCTA and traditional CCTA (all P>0.05). Conclusion:The deep learning reconstruction algorithm can not only improve the quality of the original image to a certain extent on dynamic CTP, but also extract high-quality single-phase CCTA to meet clinical diagnosis and realize a “one-stop” dynamic myocardial perfusion examination, which will help simplify the examination process, reduce contrast agent and radiation doses in the future.

Objective:To observe the effect of Wenyang Huazhuo recipe (WYHZ) on pregnancy outcomes in patients with unexplained recurrent spontaneous abortion (URSA).Methods:A retrospective cohort study was used and 240 cases of pregnancy URSA patients with spleen kidney yang deficiency syndrome at the Reproductive Center, First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and Department of Gynaecology and Obstetrics, General Hospital of Tianjin Medial University from November 2018 to March 2022 were recruited. The patients were assigned to WYHZ group (120 cases) and control group (120 cases) based on whether accepting oral WYHZ from 3 months before pregnancy to 8-12 weeks after pregnancy regularly. Pregnancy outcomes, perinatal period outcomes and obstetric complications were compared between the two groups. Multivariate logistic regression were used to analyze the effect of WYHZ on pregnancy outcome.Results:The live birth rate and the clinical pregnancy rate in WYHZ group [86.67% (104/120), 90.00% (108/120)] were higher than those in control group [71.67% (86/120), P=0.004; 75.00% (90/120), P=0.002]. The early abortion rate in WYHZ group [10.08% (12/119)] was lower than that in control group [25.86% (30/116), P=0.002], the differences were statistically significant. There were no significant differences in perinatal outcome and incidence rate of obstetric complications between the two groups (all P>0.05). Multivariate logistic regression analysis showed that the application of WYHZ significantly improved the live birth rate ( OR=8.818, 95% CI: 3.556-21.871, P<0.001) and sustained pregnancy rate ( OR=11.261, 95% CI: 4.262-29.751, P<0.001) in URSA patients. Conclusion:WYHZ using before and during pregnancy can significantly improve the live birth rate and the clinical pregnancy rate of URSA patients with syndrome of yang deficiency of spleen and kidney, and improve their pregnancy outcomes.
