OBJECTIVE To investigate the protective effect of 2-dodecyl-6-methoxy-2,5-diene-1,4-cyclohexanedione (DMDD), an active component from Averrhoa carambola root, on myocardial injury in diabetic mice based on the nuclear receptor coactivator 4/ferritin heavy chain 1/autophagy-related protein 8 (NCOA4/FTH1/ATG8) axis. METHODS The successfully modeled diabetic mice were randomly divided into model group and DMDD low-, medium-, and high-dose (12.5, 25, 50 mg/kg) groups, while an additional non-modeled control group was established, with 6 mice in each group. Each group received the corresponding drug solution or an equal volume of normal saline intragastically once daily for 21 consecutive days. After the administration, the levels of fasting blood glucose (FBG), serum lactate dehydrogenase (LDH), and creatine kinase isoenzyme MB (CK-MB) were measured. Myocardial pathological changes, degree of fibrosis, and myocardial cell ultrastructure were observed. Myocardial cell death index and NCOA4 protein positive index were detected. The protein expression levels of NCOA4, FTH1, ATG8, solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) in cardiac tissue were measured. RESULTS Compared with model group, each DMDD group showed significant alleviation of cardiac pathological injury and varying degrees of improvement in the myocardial cell ultrastructure. The FBG and serum LDH and CK-MB levels, the myocardial cell death index and NCOA4 protein positive index,the protein expression levels of NCOA4, FTH1, and ATG8 in cardiac tissue were significantly decreased ( P <0.001), while the protein expression levels of SLC7A11 and GPX4 were significantly increased ( P <0.001). CONCLUSIONS DMDD can reduce blood glucose levels, alleviate myocardial histopathological injury, and inhibit cell death in diabetic mice. The mechanism is associated with inhibiting excessive activation of the NCOA4/FTH1/ATG8 axis and reducing ferritinophagy.

Inherited thrombocytopenia is a group of heterogeneous inherited diseases mainly characterized by platelet count defects. It is a monogenic disease caused by mutations in various genes. Animal models are crucial for studying the pathogenesis and treatment strategies of inherited thrombocytopenia. Previous reviews on animal models of inherited thrombocytopenia have mostly focused on a single species, such as mice or zebrafish. This article systematically summarizes the construction, phenotypes, and characteristics of multiple animal models (mice, zebrafish, and primate animal) of inherited thrombocytopenia-causing genes, thereby providing a systematic reference for a comprehensive understanding of the research progress of its animal models.

As a pivotal strategy to alleviate the shortage of organ donors, xenotransplantation has achieved remarkable advances in both pre-clinical and clinical studies in recent years, driven by continuous optimization of gene modification techniques and immunosuppressive regimens. Nevertheless, clinical translation still confronts formidable challenges, including rejection and heightened infection risks, which severely compromise long-term graft survival. Consequently, the role of immunosuppressive regimens in xenotransplantation has become increasingly prominent. This article summarizes the mechanisms underlying xenogeneic immune rejection, the latest developments in immunosuppressive regimens, cutting-edge strategies for inducing immune tolerance and the major hurdles facing clinical xenotransplantation. It delves into potential optimization strategies and directions for future clinical research, aiming to offer theoretical insights and practical guidance for the safe and effective application of clinical xenotransplantation.

Non-alcoholic fatty liver disease (NAFLD) is one of the most prevalent forms of liver diseases globally. Its progression can lead to cirrhosis and end-stage liver disease, and there is currently a lack of effective pharmacological treatments. Adenosine monophosphate-activated protein kinase (AMPK), as a regulatory hub for maintaining cellular energy homeostasis, can coordinate key cellular processes such as adipogenesis, glucose metabolism, and mitochondrial functions. Its activation exerts metabolic regulatory effects through pathways including inhibiting lipogenesis, enhancing mitochondrial β-oxidation, regulating inflammation and oxidative stress, and promoting autophagy. Accordingly, AMPK emerges as a potential target for the prevention and treatment of NAFLD. Traditional Chinese Medicine (TCM), with low toxicity, high accessibility, and multi-component, multi-target synergistic effects, has demonstrated unique value in NAFLD treatment, particularly showing notable advantages in regulating the AMPK signaling pathway. Sichuan is known as the treasure house of TCM, and the active components of its authentic medicinal materials such as Coptidis Rhizoma not only reflect regional characteristics in AMPK signaling regulation but also form a multi-level metabolic regulatory network through crosstalk with pathways such as sirtuin 1 (SIRT1) and peroxisome proliferator-activated receptor α (PPARα). They can achieve specific regulation by directly activating AMPK and modulating upstream and downstream targets, exerting prominent effects in ameliorating hepatic steatosis and inflammation. This study systematically reviews the research findings on TCM for the prevention and treatment of NAFLD over the past five years, elaborating the mechanisms by which TCM treats NAFLD through regulating the AMPK signaling pathway. It aims to provide new perspectives and references for clinical diagnosis and treatment, basic research, and drug development.

Objective:To systematically review and evaluate risk prediction models for radiation dermatitis in breast cancer patients, providing a reference for developing higher-quality prediction models.Methods:A systematic search was conducted in PubMed, Embase, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, and China Biomedical Literature Database for studies related to risk prediction models for radiation dermatitis in breast cancer patients. The search timeframe was from database inception to February 28, 2024. Two researchers independently screened relevant literature based on inclusion and exclusion criteria, extracted the basic characteristics of the studies, and performed analysis. The included models were assessed for risk of bias and applicability.Results:A total of 8 articles involving 9 models were included, covering a total sample size of 1 291 cases, with 10 to 144 outcome events. The number of predictors ranged from 2 to 10, with common predictors including body mass index, smoking history, and breast volume, radiation dose, etc. The AUC values of the included models ranged from 0.76 to 0.98. The overall risk of bias for the models was relatively high, mainly due to issues related to study design, missing data handling, variable selection, and model validation.Conclusions:Existing risk prediction models for radiation dermatitis in breast cancer patients have certain limitations. It is recommended that future research further improve study designs, validate and optimize existing models, and develop high-performance risk prediction models.

Chinese Journal of Neuroanatomy 2025;41(3):281-288
Objective:Locus coeruleus(LC)noradrenergic(NEergic)neurons densely project to anterior piriform cortex(aPC).However,the modulation of LC to aPC remains unclear.Therefore,this study aims to investigate the effect of LC-aPC projection on the modulation of aPC in odor perception.Methods:The AAV-DIO-ChR2-eYFP virus was injected into LC of DBH-Cre mice and the optrode was placed into aPC.Optogenetics combined with in vivo electro-physiology were used to record the air/odor-evoked response of aPC pyramidal neurons.Results:The immunofluores-cent staining showed that the LC project directly to aPC.Activation of aPC NEergic fibers decreased the spontaneous re-sponses and odor-evoked responses of aPC pyramidal neurons.Conclusion:Activation of aPC NEergic neurons inhibits the spontaneous responses and odor-evoked responses of aPC pyramidal neurons.
