Objective To establish a chronic rejection (CR) model of mouse heart transplantation and analyze its characteristics. Methods Allogeneic BALB/c and C57BL/6 mice were used as donor and recipient for heart transplantation, and intraperitoneal injection of cytotoxic T lymphocyte-associated antigen 4-immunoglobulin (CTLA4-Ig) was given 1 and 2 days after surgery. Graft survival time, donor specific antibody (DSA) level, graft pathology and inflammatory cell infiltration were observed. Results In allogeneic transplantation model, graft survival time was prolonged after CTLA4-Ig treatment [(28.2±4.1) d vs. (7.0±0.7) d, P < 0.01]. The level of serum DSA-IgG increased at 2, 3 and 4 weeks after surgery, while the level of DSA-IgM remained unchanged. Myocardial cell injury, inflammatory cell infiltration, interstitial fibrosis and C4d deposition in capillaries were aggravated 3 weeks after operation and worsened 4 weeks after operation. The infiltrated immune cells were mainly macrophages, T cells and plasma cells. Conclusions Mouse allogeneic heart transplantation combined with CTLA4-Ig successfully establishes a CR model, which provides a basis for subsequent studies on the pathogenesis and intervention of CR.

Objective:
To evaluate the feasibility of dynamic contrast-enhanced MRI (DCE-MRI) in differentiating tumor deposits (TDs) from metastatic lymph nodes (MLNs) in rectal cancer.
Materials and Methods:
A retrospective analysis was conducted on 70 patients with rectal cancer, including 168 lesions (70 TDs and 98 MLNs confirmed by histopathology), who underwent pretreatment MRI and subsequent surgery between March 2019 and December 2022. The morphological characteristics of TDs and MLNs, along with quantitative parameters derived from DCE-MRI (K trans , kep, and v e) and DWI (ADCmin, ADCmax, and ADCmean), were analyzed and compared between the two groups.Multivariable binary logistic regression and receiver operating characteristic (ROC) curve analyses were performed to assess the diagnostic performance of significant individual quantitative parameters and combined parameters in distinguishing TDs from MLNs.
Results:
All morphological features, including size, shape, border, and signal intensity, as well as all DCE-MRI parameters showed significant differences between TDs and MLNs (all P < 0.05). However, ADC values did not demonstrate significant differences (all P > 0.05). Among the single quantitative parameters, v e had the highest diagnostic accuracy, with an area under the ROC curve (AUC) of 0.772 for distinguishing TDs from MLNs. A multivariable logistic regression model incorporating short axis, border, v e, and ADC mean improved diagnostic performance, achieving an AUC of 0.833 (P = 0.027).
Conclusion
The combination of morphological features, DCE-MRI parameters, and ADC values can effectively aid in the preoperative differentiation of TDs from MLNs in rectal cancer.

OBJECTIVE To provide technical support for improving recognition rate of adverse drug events (ADEs) related to traditional Chinese medicine (TCM) formula granules and decoction pieces among inpatient patients. METHODS By referencing the global trigger tool (GTT) whitepaper, literature on adverse reactions to TCM, and expert review opinions, ADE trigger items for TCM formula granules and decoction pieces used in the inpatients were established. GTT was applied to analyze ADEs in inpatients who had used TCM formula granules and decoction pieces in our hospital from August 2013 to August 2023, utilizing the Chinese Hospital Pharmacovigilance System. The effectiveness of GTT and the characteristics of these ADEs were analyzed. RESULTS A total of forty-eight triggers were established, including thirty-two laboratory test indexes, thirteen clinical symptoms, and three antidotes. Among the 1 682 patients included, GTT identified 652 potential ADEs, 284 true positive ADEs,with a trigger rate of 38.76% and a positive predictive value of 43.56%. After review by the auditor, 278 cases of ADEs were finally confirmed, with an incidence rate of 16.53%, significantly higher than the number of spontaneously reported ADEs during the same period (0). The 278 cases of ADEs were mostly grade 1 (223 cases), mainly involving hepatobiliary system, gastrointestinal system, blood- lymphatic system, etc;a total of 219 types of TCMs are involved,and the top five suspected TCMs used at a frequency higher than 1% were Poria cocos, Codonopsis pilosula, Atractylodes macrocephala, fried Glycyrrhiza uralensis, and Scutellaria baicalensis. CONCLUSIONS The established GTT can improve the recognition rate of ADEs for hospitalized patients using traditional Chinese medicine formula granules and decoction pieces.

Journal of Sun Yat-sen University(Medical Sciences) 2025;46(1):11-20
In the process of accelerating the construction of a strong country in health and sports in China, the mode of promoting health has shifted from passive health to active health. Guided by the concept of “active health”, there is a new understanding of the relationship between sports, health, and medical care. The integration of sports and medicine is a concrete manifestation and implementation of the concept of “active health”, and an important measure to implement the Healthy China strategy, which is regarded as an important strategy to promote public health reform. This article reviews the historical path of the integration of sports and medicine from its concept to practical implementation, and finds that China proposed the integration of sports and medicine relatively late, but it has become an intense focus of academic research; The sports and medical departments have launched guidelines for chronic disease exercise and standards related to exercise prescriptions, and local governments in China have explored diversified models of integrating sports and medicine; Under the institutional requirements of top-level design, the exploration of the “integration of sports and medicine” model is flourishing. There are currently problems in promoting the integration of sports and medicine, such as the lack of a “sports and medicine integration” system and a shortage of “sports and medicine integration” talents. Drawing on the international experience of integrating sports and medical services in other countries,We propose a development strategy of “concept first, government leading, and sports and medical cooperation”; We recommend institutional optimization such as improving medical insurance related systems, establishing certification, employment, and management systems for integrated sports and medical talents, and improving the training system for integrated sports and medical talents in universities; We also advocate propose a “dual wheel” promotion path of upgrading hospital rehabilitation centers and expanding community health centers, in order to provide reference for policy formulation and promote the integration of sports and medicine to play a greater role in China’s public health.

ObjectiveTo investigate the effect of nicotinamide adenine dinucleotide on vascular endothelial injury in hypertension and its molecular mechanism. MethodsC57BL/6J mice were randomly divided into saline group (Saline) and hypertension group (Ang Ⅱ, which were infused with Ang Ⅱ via subcutaneously implanted osmotic pumps), and supplemented daily with nicotinamide mononucleotide (300 mg/kg), a precursor of NAD+. Blood pressure, endothelial relaxation function and pulse wave velocity were measured after 4 weeks. Wound healing assay and adhesion assay were used to evaluate the function of endothelial cells in vitro. mtROS levels were detected by immunofluorescence staining. RT-PCR was used to detect the mRNA expression of mtDNA, SIRT3 and isocitrate dehydrogenase 2 (IDH2). 8-hydroxy-2'-deoxyguanosine levels were detected by enzyme-linked immunosorbent assay. The protein expression levels of p-eNOS, eNOS, SIRT3 and IDH2 were detected by Western blot. ResultsNMN supplementation reduced blood pressure (P<0.001) and improved endothelial function and arterial stiffness (P<0.001) in hypertensive mice. In vitro, NMN improved endothelial function in AngII-stimulated endothelial cells (P<0.05) and attenuated mitochondrial oxidative stress levels (P<0.001). Mechanistically, NMN elevated SIRT3 activity (P<0.001), which subsequently enhanced IDH activity (P<0.001) and reduced oxidative stress levels in endothelial cells. Conversely, knockdown of IDH2 would reverse the effect of SIRT3 in improving endothelial function (P<0.001). ConclusionNAD+ lowers blood pressure and enhances vascular function in hypertension by reducing the level of oxidative stress in endothelial cells through activation of the SIRT3/IDH2 signal pathway.

ObjectiveTo investigate the prevalence rate of chronic non-communicable diseases (NCDs) and the association with quality of life in middle-aged and elderly patients with HIV/AIDS. MethodsThis cross-sectional study surveyed 432 patients with HIV/AIDS (aged≥45 years) in the Infectious Disease Center in Guangzhou Eighth People’s Hospital of Guangzhou Medical University, and 366 participants were included in the analysis after quality control. A questionnaire and the EuroQol 5-Dimensional 3-level version (EQ-5D-3L) were used to investigate NCDs and quality of life and Tobit regression model was used to estimate the association between chronic diseases and quality of life. ResultsAmong the 366 participants, 29(7.9%) had cardiovascular disease, 45(12.3%) had hypertension, 122(33.3%) had hyperglycemia, 151(41.3%)had hyperlipidemia,7(1.9%) had cancer, 17 (4.6%) had chronic kidney disease, 38 (10.4%) had chronic liver disease, 21(5.7%) had musculoskeletal disorders, and 253(69.1%) suffered from at least one type of chronic diseases. The median (lower and upper quartiles) of EQ-5D utility index was 1.000(0.964~1.000). Multivariate Tobit regression results of the total population showed that cancer [ba=-0.08,95%CI (-0.15,-0.01),P=0.036], chronic kidney disease [ba=-0.07, 95%CI (-0.12,-0.02),P=0.006], musculoskeletal disease [ba=-0.09, 95%CI (-0.13, -0.05),P<0.001], and ≥3 types of chronic diseases[ba=-0.05, 95%CI(-0.08,-0.01),P=0.013] were negatively correlated with EQ-5D utility index. The stratified analysis results of different CD4+T cell levels showed that hypertension [ba=-0.07, 95%CI (-0.12, -0.02), P=0.007], chronic kidney disease [ba=-0.10,95%CI (-0.18,-0.03), P=0.006], musculoskeletal disease [ba=-0.15, 95%CI (-0.22,-0.07), P<0.001] and ≥3 types of chronic diseases [ba=-0.09, 95%CI (-0.09, -0.01), P<0.001] were negatively correlated with EQ-5D utility index in the group with CD4≤500 (cells/μL), whereas cancer[ba=-0.11, 95%CI (-0.20,-0.01), P=0.031] was negatively correlated with EQ-5D utility index in the group with CD4>500(cells/μL). ConclusionsThe prevalence rate of chronic non-communicable diseases in middle-aged and elderly patients with HIV/AIDS is relatively high. The classification of NCDs such as cancer or chronic kidney disease or other chronic diseases and the numbers of NCDs categories are negatively correlated with quality of life. However,this association varies among patients with HIV/AIDS of different CD4+T cell levels. It is suggested that we should try to prevent and identify NCDs at an early stage, strengthen linkages and integration of health services for AIDS and chronic NCDs, and jointly manage and control AIDS with chronic diseases to improve the quality of life among people living with HIV/AIDS.

OBJECTIVE To investigate the improvement mechanism of hyperoside (HYP) on non-alcoholic fatty liver disease (NAFLD). METHODS Male C57BL/6 mice were randomly divided into normal (NFD) group, model (HFD) group and HYP group, with 8 mice in each group. Except for NFD group, the mice in other groups were fed with HF60 high-fat diet to establish NAFLD model; HYP group was simultaneously given HYP 100 mg/kg intragastrically every day, for 16 consecutive weeks. The body weight and liver weight of mice in each group were recorded 16 h after the last medication; the histopathological changes and lipid accumulation in the liver were observed, and the contents of triglyceride (TAG) in liver tissue and serum contents of TAG, aspartate transaminase (AST) and alanine transaminase (ALT) were measured; LC-MS/MS method was adopted to detect lipid changes in the liver tissue of mice for lipidomics analysis, and protein expressions of lipid synthesis-associated proteins peroxisome proliferator-activated receptor α (PPARα) were also tested. Human hepatocellular carcinoma cell line HepG2 was divided into normal control group, model group, HYP low-concentration group (50 μmol/L), HYP high-concentration group (100 μmol/L), HYP low-concentration+GW6471 (PPARαinhibitor) group, and HYP high-concentration+GW6471 group. Except for normal control group, the remaining cells were induced with oleic acid and palmitic acid to establish a high-fat cell model. The accumulation of lipid droplets in each group of cells was observed, and the TAG content was detected. RESULTS Compared with HFD group, HYP group exhibited significant reductions in liver fat vacuoles, lipid accumulation, liver weight, and TAG content in liver tissue, as well as serum contents of ALT, AST and TAG (P<0.05). Additionally, the expression of PPARα protein in liver tissue was significantly increased (P<0.05), and the pathological morphological changes associated with NAFLD were alleviated. Lipidomic analysis revealed that HYP significantly reduced the levels of TAG, diacylglycerol and other lipids in the liver. Compared with model group, cellular lipid droplet accumulation and TAG content decreased significantly in HYP low- and high-concentration groups (P<0.05); GW6471 could significantly reverse the improvement effect of HYP on above indicators (P<0.05). CONCLUSIONS HYP can effectively ameliorate NAFLD induced by a high-fat diet in mice, and the mechanism may be related to the activation of PPARα to regulate hepatic lipid synthesis.
