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.

ObjectiveTo meet the requirements of Good Laboratory Practice (GLP), Sichuan Institute for Drug Control (Sichuan Testing Center of Medical Devices, Sichuan Institute of Musk Deer Breeding) Safety Evaluation Center (hereinafter referred to as the center) conducts a targeted validation study to address the lack of supporting data for the specified validity periods of disinfectants, feed, and bedding during their use in laboratory animal facilities. The study summarizes practical experience in material management and provides a scientific basis for the standardized management of materials in the facility. MethodsUnder the routine operating conditions of the laboratory animal facility at the center, the disinfection efficacy of four commonly used disinfectants was confirmed using the quantitative suspension kill test, with the disinfectants tested on day 0, day 7, and at 1, 2, and 3 months after preparation and after opening; for laboratory animal feed, nutritional components, chemical contaminants, and microbial indicators were tested 7 days after opening; microbial indicators of laboratory animal corncob bedding were tested after storage for 7 days following opening and sterilization. ResultsUnder the GLP management system of our center, the disinfection efficacy log reduction values of prepared 0.04% sodium hypochlorite solution, 0.1% didecyldimethylammonium bromide solution, and 0.2% benzalkonium bromide solution were all ≥5 on days 0 and 7. The log reduction values of opened 75% ethanol were ≥5 on days 0 and 7 and at 1, 2, and 3 months after opening. All disinfectants were therefore qualified and effective. Compared with the factory inspection data, the nutritional components, chemical contaminants, and microbial indicators of SPF-grade rat and mouse maintenance feed, SPF-grade guinea pig growth and reproduction feed, conventional-grade guinea pig growth and reproduction feed, rabbit maintenance feed, and dog maintenance feed showed a slight overall downward trend but no significant differences 7 days after opening. The microbial indicators of specialized corncob bedding for SPF-grade laboratory animals stored for 7 days after opening and conventional-grade corncob bedding stored for 7 days after sterilization showed no significant fluctuations. All indicators still met the relevant requirements of GB/T 14924.2—2001 Laboratory Animals—Hygienic Standard for Formula Feeds and GB 14924.3—2010 Laboratory Animals—Nutrients for Formula Feeds. ConclusionBased on practical experience in managing the center's GLP laboratory animal facility and validation of core quality indicators, the specified validity periods of disinfectants, feed, and bedding meet the quality requirements, providing a practical reference for the standardized management of laboratory animal facilities.

As a key member of the insulin-like growth factor family, insulin-like growth factor-Ⅰ (IGF-Ⅰ) is mainly synthesized in the liver and is widely distributed in the human body, and it is involved in the physiological processes such as cell proliferation, differentiation, metabolism, and apoptosis. Studies have shown that the level of IGF-Ⅰ is negatively correlated with the severity of liver cirrhosis, and IGF-Ⅰ mainly affects the progression of liver cirrhosis by inhibiting liver fibrosis, promoting DNA damage repair, and regulating lipid metabolism. Monitoring of IGF-Ⅰ level is expected to provide an evaluation indicator for improving the prognosis of patients with liver cirrhosis, and stimulating the action pathway of IGF-Ⅰ or regulating its expression level may become a new method for the treatment of liver cirrhosis. This article reviews the research advances in IGF-Ⅰ in liver cirrhosis, in order to provide new ideas for the diagnosis and treatment of liver cirrhosis.

Under the background of the Healthy China strategy, the integration of traditional Chinese medicine (TCM) into the public health emergency response system has become an important measure to enhance the capacity for coping with public health emergencies. In recent years, the role of TCM in responding to such emergencies has become increasingly prominent. Taking major emerging epidemics as an example, TCM has developed a rich theoretical system and practical experience in epidemic prevention and treatment over thousands of years, and has played a significant role in successive outbreaks with its unique advantages. Based on the concept of ''preventing disease before its onset'' and the theoretical framework of treatment based on syndrome differentiation, TCM has achieved remarkable results through early intervention and full participation in the integrated model of TCM and Western medicine, from severe acute respiratory syndrome (SARS) to corona virus disease-2019 (COVID-19), in improving clinical symptoms and outcomes, reducing adverse reactions, and promoting recovery. From the perspective of the Healthy China strategy, this paper systematically reviews the historical development of TCM in epidemic prevention and treatment, with particular attention to recent epidemics such as SARS, influenza A (H1N1), and COVID-19. It further examines the similarities and differences between TCM and Western medicine in responding to major emerging epidemics, as well as relevant policies related to TCM in epidemic prevention and control. In addition, it summarizes the existing problems in TCM's role in the prevention and treatment of major emerging epidemics, and explores measures to improve its rapid response capacity under the Healthy China strategy. This study not only provides a ''Chinese solution'' for the prevention and control of newly emerging infectious diseases worldwide, but also offers theoretical and practical references for strengthening the public health emergency response system, carrying strategic significance for promoting the modernization and internationalization of TCM.

Objective Inflammation and fibrosis are key features of diabetic nephropathy(DN).Triptolide(TP)exhibits anti-inflammatory and anti-fibrotic properties,though its mechanisms of action in DN remain unclear.CREKA(Cys-Arg-Glu-Lys-Ala)is a pentapeptide that specifically binds to fibronectin(FN),and the CREKA-modified liposome(CREKA-Lip)represents a novel FN-targeted drug delivery system.This study aimed to investigate the role of TP in diabetic db/db mice and determine whether encapsulation within CREKA-Lip enhances therapeutic efficacy while reducing the multi-organ toxicity of TP.Methods Eight-week-old diabetic db/db mice received tail vein injections twice weekly with vehicle,free TP,or CREKA-Lip/TP for 10 weeks.Urine and serum parameters were measured,and kidney,heart,liver,and testis tissues were collected for pathological evaluation.Protein-protein interaction networks were constructed using Cytoscape and its plug-ins to identify core targets and elucidate the therapeutic mechanism of TP against DN.Inflammatory,fibrotic,apoptotic,and lipid metabolism markers were evaluated in the kidneys of diabetic mice with DN and in high glucose-treated mouse mesangial cells and podocytes using qPCR,Western blot,immunohistochemistry,and immunofluorescence assays.Results TP administration reduced fasting blood glucose levels and glomerular mesangial expansion in diabetic mice.TP significantly suppressed renal inflammation,fibrosis,and apoptosis while enhancing lipid metabolism.Integration of network pharmacology,molecular docking,and transcriptomics revealed that TP ameliorated DN by inhibiting the JAK2-STAT1 signaling pathway.In vitro,TP inhibited high glucose-induced phosphorylation of JAK2 and STAT1,reduced collagen production in mesangial cells,decreased apoptosis,and improved lipid metabolism in podocytes.Moreover,CREKA-Lip/TP exhibited superior efficacy compared with free TP,with a more sustained reduction in urine albumin-to-creatinine ratio and greater inhibition of mesangial expansion.Notably,CREKA-Lip/TP treatment did not induce systemic toxicity.Conclusion TP improves renal inflammation,fibrosis,apoptosis,and lipid homeostasis,thereby ameliorating DN by inhibiting JAK2-STAT1 activation.Targeted delivery of TP via FN-binding CREKA-Lip enhances therapeutic efficacy while minimizing multi-organ toxicity.
