In the context of the development of transplant oncology, it is of great clinical significance to find a drug with both antitumor and immunosuppressive effects for liver transplantation patients with hepatocellular carcinoma (HCC). The antitumor effect of ginkgolic acid (GA) has been confirmed, and some studies suggest that GA may also have an immunosuppressive effect. The immunosuppressive effect of GA was evaluated by histopathology, T-cell subpopulation, and cytokine detection in rat liver transplantation and mouse cardiac transplantation models, and transcriptomic and metabolomic analysis was used to explore the underlying mechanism of the GA immunosuppressive effect. Metabolites, activation, and ferroptosis markers of CD8⁺ T cells were detected in vivo and in vitro. Based on rat liver transplantation and mouse cardiac transplantation models, the immunosuppressive effect of GA was first confirmed by histopathology, T-cell subpopulation, and cytokine detection. In the mouse cardiac transplantation model, transcriptomics combined with metabolomics demonstrated for the first time that GA inhibited lactate dehydrogenase A (LDHA) expression and pyruvate metabolism in CD8⁺ T cells. It was confirmed in vivo and in vitro that GA inhibited pyruvate metabolism of CD8⁺ T cells through LDHA, inhibiting their activation and inducing ferroptosis. Overexpression of LDHA partially reversed the effect of GA on the metabolism, activation, and ferroptosis of CD8⁺ T cells in vitro. GA mediates metabolic reprogramming through LDHA to inhibit the activation and induce ferroptosis of CD8⁺ T cells to exert an immunosuppressive effect, which lays an experimental foundation for the future clinical application of its immunosuppressive effect.

Objective: To establish a progressive research strategy for “colonic components analysis - efficacy verification and mechanism exploration - gut microbiota”, screen pharmacodynamic substances, and investigate their mechanism via gut microbiota. Methods: The pharmacodynamics of Gegen Qinlian decoction (GQD) were assessed using a mouse model of dextran sulfate sodium-induced ulcerative colitis (UC). Ultra-performance liquid chromatography-quadrupole-orbitrap mass spectrometer was used to identify the prototype and metabolic components of GQD in the colon during UC. To analyze the structure and function of characteristic genera of GQD and its active components, 16S rRNA sequencing was performed. Results: We identified 67 prototypic and 14 metabolic components of GQD in the UC colon. The primary prototype components are flavonoids and alkaloids, including puerarin (PUE), baicalin (BAI), and berberine (BER). The metabolism was predominantly sulfonation. Efficacy verification showed that the main active components, puerarin, baicalin, and berberine, had good therapeutic effects on UC. The results of 16S rRNA gene sequencing showed that GQD improved UC by regulating the structure and function of the gut microbiota. The abundance of gut microbiota involved in the metabolism of the prototype components was influenced by the corresponding components. The function prediction results showed that PUE was the most comparable to GQD, with 24 consistent pathways. BAI and BER showed comparable gut microbiota regulation pathways. Characteristic pathways of BER include glucometabolic processes. Conclusion This study focused on the key issues in the gut microbiota pathway and developed a progressive research strategy to understand the transformation mechanisms of colonic components. This research systematically analyzed the active components and metabolic transformation of GQD in the colon during the pathological state of UC, as well as changes in the structure and function of the gut microbiota, clarified the mechanism of GQD and its active components in improving UC via the gut microbiota pathway.

Objective:To systematically review the real experience of type 1 diabetes in adolescents.Methods:The qualitative research on the experience of type 1 diabetes in adolescents was electronically searched in PubMed, Web of Science, Embase, EBSCO, Cochrane Library, China Biology Medicine disc, WanFang Database, China National Knowledge Infrastructure, and VIP. The search period was from database establishment to July 2023. Two evidence-based trained researchers independently conducted literature screening and data extraction, and the results were integrated using the Meta-synthesis.Results:A total of 13 articles were included, 42 results were extracted and classified into 11 categories, which were integrated into four results, namely disease perception, complex psychological experiences, disease management, and post-traumatic growth.Conclusions:The awareness and psychological experience of type 1 diabetes in adolescents should be paid attention to. Medical institutions, families and schools should provide all-round support for adolescents with type 1 diabetes to help them enhance their disease self-management, improve their health outcomes and promote their post-traumatic growth.

【Objective】 To clarify the concept of health literacy among children and adolescents with accidental injuries through literature review and analysis. 【Methods】 A systematic search was conducted across multiple databases, including China National Knowledge Infrastructure, Wanfang database, VIP database, China Biomedical literature database, PubMed, CINAHL, and PscyINFO database. The literature was analyzed using Rodgers′ evolutionary concept analysis method. 【Results】 A total of 56 articles were included. The health literacy of children and adolescents with accidental injuries comprised three conceptual attributes:cognition, emotion and behavior. The influencing factors included children′s demographic factors, family and school related factors and social related factors. The result can be beneficial to reduce the occurrence of injury events, save family economic expenditure and alleviate the burden on social medical resources. However, there is currently a lack of specific measurement tools for assessing health literacy in this population, as the existing evaluation items are drawn from general health literacy scales. 【Conclusions】 The concept of health literacy among children and adolescents with accidental injuries is multifaceted and evolving. Future research should focus on exploring the characteristics of health literacy among children and adolescents of different ages and regions from their own perspectives. Additionally, efforts should be made to refine the concept and develop specialized measurement tools to facilitate further studies in this area.

Environmental pollution is closely linked to the occurrence and development of cancer. Chemical carcinogens are the most important environmental factors causing cancer in humans. Among them, persistent organic pollutants (POPs) are characterized by their widespread distribution, persistence, and bioaccumulation. Research on the carcinogenic effects of POPs has received considerable attention in recent years. This article reviewed the internal exposure, association with cancer risk, and potential carcinogenic mechanisms of five typical classes of POPs in the environment, including polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), per- and poly-fluoroalkyl substances (PFAS), brominated flame retardants (BFRs), and short-chain chlorinated paraffins (SCCPs). These five types of POPs have distinct carcinogenic mechanisms, including interfering with cell proliferation cycle, altering epigenetic inheritance, promoting oxidative stress, altering energy metabolism, and affecting immune function. The development of cancer is the result of interaction between intrinsic genetic factors and external environmental factors. In addition to focusing on how environmental POPs affect the genetic material of organisms, it is also important to consider their effects on the tumor microenvironment, including tumor immunity and angiogenesis. Understanding these effects is crucial for guiding future efforts in pollution control and precision medicine in cancer treatment.

21 hydroxylase deficiency (21-OHD), the most common form of congenital adrenal hyperplasia, is caused by defects in CYP21A2 gene, which encodes the cytochrome P450 oxidase (P450C21) involved in glucocorticoid and mineralocorticoid synthesis. The diagnosis of 21-OHD is based on the comprehensive evaluation of clinical manifestation, biochemical alteration and molecular genetics results. Due to the complex structure of CYP21A2, special techniques are required to perform delicate analysis to avoid the interference of its pseudogene. Recently, the state-of-the-art diagnostic methods were applied to the clinic gradually, including the steroid hormone profiling and third generation sequencing. To standardize the laboratory diagnosis of 21-OHD, this consensus was drafted on the basis of the extensive knowledge, the updated progress and the published consensuses and guidelines worldwide by expert discussion organized by Rare Diseases Group of Pediatric Branch of Chinese Medical Association, Medical Genetics Branch of Chinese Medical Doctor Association, Birth Defect Prevention and Molecular Genetics Branch of China Maternal and Child Health Association. and Molecular Diagnosis Branch of Shanghai Medical Association.
