ObjectiveAge-related macular degeneration (AMD) is one of the leading causes of low vision and blindness in people over 50 years old, and dry AMD (dAMD) is one type for which there is currently no clear treatment. On the basis of the diagnosis and clinical characteristics of dAMD in traditional Chinese and Western medicine, this paper evaluated the fitting degrees of existing animal models of dAMD with clinical characteristics according to the evaluation methods of animal models, and put forward suggestions and prospects. MethodsLiterature on animal models of dAMD was searched against database, and the characteristics of the models were assigned according to the diagnosis criteria of diseases and syndromes of traditional Chinese and Western medicine, and the fitting degrees of the models with clinical characteristics were analyzed and evaluated. ResultsAt present, the animal models of dAMD are mainly established targeting complement factors, chemokines, oxidative damage, lipid/glucose metabolism, and natural strains. Most of the models can simulate the major pathological changes of dAMD, showing the fitting degree of 25%-50% with clinical characteristics in Western medicine. However, the evaluation of traditional Chinese medicine (TCM) syndromes, especially the evaluation of secondary syndromes, is missing, and the models present low fitting degrees with the clinical characteristics in TCM. ConclusionExisting animal models of dAMD are mostly established under the guidance of Western diagnostic standards, which reproduce the main disease characteristics of Western medicine and lack observation of TCM syndromes. Future studies can pay attention to the intervention factors and evaluation systems of spleen deficiency Qi deficiency and liver-kidney Yin deficiency syndrome and build the animal model of dAMD with integration of disease and syndrome based on clinical characteristics of traditional Chinese and Western medicine.

ObjectiveTo examine the influences of Shenfu injection on the endogenous metabolic byproducts in the myocardium of the rat model exhibiting chronic heart failure, thus deciphering the therapeutic mechanism of the Qi-reinforcing and Yang-warming method. MethodsSD rats were randomly allocated into a control group and a modeling group. Chronic heart failure with heart-Yang deficiency syndrome in rats was modeled by multi-point subcutaneous injection of isoproterenol, and the rats were fed for 14 days after modeling. The successfully modeled rats were randomized into model, Shenfu injection (6.0 mL·kg-1), and trimetazidine (10 mg·kg-1) groups and treated with corresponding agents for 15 days. The control group and the model group were injected with equal doses of normal saline, and the samples were collected after the intervention was completed. Cardiac color ultrasound was performed. Hematoxylin-eosin (HE) staining was used to observe histopathological morphology, and the serum level of N-terminal pro-brain natriuretic peptide (NT-proBNP) was assessed by enzyme-linked immunosorbent assay (ELISA). The mitochondrial morphological and structural changes of cardiomyocytes were observed by transmission electron microscopy, and the metabolic profiling was carried out by ultra high performance liquid chromatography-quantitative exactive-mass spectrometry (UHPLC-QE-MS). Differential metabolites were screened and identified by orthogonal partial least squares-discriminant analysis (OPLS-DA) and other methods, and then the MetaboAnalyst database was used for further screening. The relevant biological pathways were obtained through pathway enrichment analysis. The receiver operating characteristic (ROC) curve was established to evaluate the diagnostic value of each potential biomarker for myocardial injury and the evaluation value for drug efficacy. ResultsThe results of color ultrasound showed that Shenfu Injection improved the cardiac function indexes of model rats (P<0.05). The results of HE staining showed that Shenfu injection effectively alleviated the pathological phenomena such as myocardial tissue structure disorder and inflammatory cell infiltration in model rats. The results of ELISA showed that Shenfu injection effectively regulated the serum NT-proBNP level in the model rats. Transmission electron microscopy (TEM) showed that Shenfu injection effectively restored the mitochondrial morphological structure. The results of metabolomics showed that the metabolic phenotypes of myocardial samples presented markedly differences between groups. Nine differential metabolites could be significantly reversed in the Shenfu injection group, involving three metabolic pathways: pyruvate metabolism, histidine metabolism, and citric acid cycle (TCA cycle). The results of ROC analysis showed that the area under the curve (AUC) values of all metabolites were between 0.75 and 1.0, indicating that the differential metabolites had high diagnostic accuracy for myocardial injury, and the changes in their expression levels could be used as potential markers for efficacy evaluation. ConclusionShenfu injection significantly alleviated the damage of cardiac function, myocardium, and mitochondrial structure in the rat model of chronic heart failure with heart-Yang deficiency syndrome by ameliorating energy metabolism remodeling. Reinforcing Qi and warming Yang is a key method for treating chronic heart failure with heart-Yang deficiency syndrome.
4.Expert recommendations on vision friendly built environments for myopia prevention and control in children and adolescents
Chinese Journal of School Health 2026;47(1):1-5
Abstract
The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas:optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

ObjectiveTo investigate the therapeutic efficacy of Danggui Shaoyaosan (DSS) on renal injury in db/db mice and its impact on endoplasmic reticulum stress (ERS) in renal tissues. MethodsThirty 8-week-old male db/db mice and six db/m mice were acclimated for one week, after which urinary microalbumin and blood glucose levels were monitored to establish a diabetic kidney disease (DKD) model. The model mice were randomly divided into a model group, an irbesartan group, and three DSS treatment groups with different doses (16.77, 33.54, and 67.08 g·kg-1·d-1). A normal group was set as control. Each group was intragastrically administered with the corresponding drugs or saline for 8 weeks. After the intervention, general conditions were observed. Serum cystatin C (Cys-C), 24-hour urinary total protein (24 h-UTP), 24-hour urinary microalbumin (24 h-UMA), urinary creatinine (Ucr), and urea nitrogen (UUN) were measured. Transmission electron microscopy (TEM) was used to observe glomerular basement membrane (GBM) and ultrastructural changes of the endoplasmic reticulum (ER) in glomerular endothelial cells. Western blot, real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and immunohistochemistry were used to analyze renal tissue structure and the expression of GRP78, CHOP, and related markers. ResultsCompared with the normal group, the mice in the model group showed curled posture, sluggish response, poor fur condition, increased levels of Cys-C, 24 h-UTP, 24 h-UMA, and UUN (P<0.05), while Ucr decreased (P<0.05). The GBM was significantly thickened, with podocyte and foot process fusion. The protein expressions of GRP78, CHOP, and ATF6 were significantly upregulated (P<0.05), the mRNA levels of GRP78 and CHOP increased (P<0.05), and immunohistochemistry showed an enhanced GRP78 signal (P<0.05). After treatment, the mice exhibited improved behavior, normalized GBM and podocyte structure, improved ER morphology and markedly better biochemical indicators. Western blot, Real-time PCR, and immunohistochemistry indicated that the ERS-related markers were downregulated in the DSS treatment groups (P<0.05), suggesting alleviated ERS and improved renal function. ConclusionDSS can effectively ameliorate renal pathological damage in db/db mice, possibly by regulating ERS in glomerular endothelial cells, although the underlying signaling mechanisms require further investigation.

ObjectiveTo establish a new noninvasive, simple, and convenient clinical predictive model by identifying independent predictive factors for rebleeding after endoscopic therapy in cirrhotic patients with esophagogastric variceal bleeding (EGVB), and to provide a basis for individualized risk assessment and development of clinical intervention strategies. MethodsCirrhotic patients with EGVB who were diagnosed and treated in The First Affiliated Hospital of Xi’an Medical University from September 2018 to October 2023 were enrolled as subjects, and according to whether the patient experienced rebleeding within 1 year after endoscopic therapy, they were divided into rebleeding group with 93 patients and non-rebleeding group with 84 patients. Clinical data were collected and analyzed. The independent samples t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A Logistic model was established based on the results of the univariate and multivariate analyses, and the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) were used to assess the accuracy of the model. R software was used to visualize the model by plotting a nomogram, and the Bootstrap method was used for internal validation of the model. ResultsThe multivariate analysis showed that red blood cell count (RBC), cholinesterase (ChE), alkaline phosphatase (ALP), albumin (Alb), thrombin time (TT), portal vein trunk diameter, sequential therapy, and primary prevention were independent predictive factors for rebleeding. Based on the results of the multivariate analysis, a logistic model was established as logit(P)=-0.805-1.978×(RBC)+0.001×(ChE)-0.020×(ALP)-0.314×(Alb)+0.567×(TT)+0.428×(portal vein trunk diameter)-2.303×[sequential therapy (yes=1, no=0)]-2.368×[primary prevention (yes=1, no=0)]. The logistic model (AUC=0.928, 95% confidence interval [CI]: 0.893—0.964, P<0.001) had a better performance in predicting rebleeding than MELD score (AUC=0.603, 95%CI: 0.520—0.687, P=0.003), Child-Pugh class (AUC=0.650, 95%CI: 0.578—0.722, P=0.001), and FIB-4 index (AUC=0.587, 95%CI: 0.503—0.671, P=0.045). The model had an optimal cut-off value of 0.607, a sensitivity of 0.817, and a specificity of 0.817. Internal validation confirmed that the model had good predictive performance and accuracy. ConclusionSequential therapy, implementation of primary prevention, an increase in RBC, and an increase in Alb are protective factors against rebleeding, while prolonged TT and widened main portal vein diameter are risk factors. The logistic model based on these independent predictive factors can predict rebleeding and thus holds promise for clinical application.

ObjectiveTo explore the role of neuroimaging features monitored by functional near-infrared spectroscopy (fNIRS) in postoperative delirium (POD) in elderly patients undergoing joint replacement during perioperative period, and to provide a basis for early clinical prediction. MethodsA total of 105 elderly patients who underwent joint replacement under general anesthesia were included. The Mini-Mental State Examination (MMSE) scale was used to evaluate the patient's cognition one day before the operation. Before the start of the surgery, fNIRS was used to monitor the changes of cerebral blood oxygen saturation when the patient performed the task state. The 3-minute delirium diagnostic scale (3D-CAM scale) was used to evaluate the occurrence of POD at 24, 48 and 72 h after operation. Brain network analysis was performed and Logistic regression analysis was used to explore the relationship between fNIRS monitoring data and POD in elderly patients undergoing joint replacement surgery during preoperative task state. The receiver operating characteristic curve (ROC curve) was constructed to evaluate the diagnostic efficacy, and the Hosmer-Lemeshow goodness-of-fit test was used to test the goodness of fit of the model. ResultsAmong 105 patients, 100 cases were effectively analyzed, of which 20 cases (20%) had POD. Brain network analysis showed that the r value of functional connectivity correlation coefficient in POD group (0.069±0.118) was lower than that in non-POD group (0.073±0.084). The low channel connectivity of right primary somatosensory cortex-right primary motor cortex (RS1-RM1) and left anterior pole-right Broca's triangle (LFP-RBA44) was an important factor affecting the occurrence of POD (P < 0.05). Based on this result, the area under the ROC curve was 0.797 and 0.784, respectively. The results of Hosmer-Lemeshow goodness-of-fit test showed that the model fitted well (all P>0.5). ConclusionThe neuroimaging features extracted from the cerebral oxygen saturation data monitored by fNIRS are significantly correlated with the risk of POD in elderly patients undergoing joint replacement during perioperative period. Among them, the low connectivity of preoperative RS1-RM1 and LFP-RBA44 brain network channels is an important influencing factor of POD occurrence. Predicting the occurrence of POD based on fNIRS is conducive to the early intervention and risk reduction of perioperative complications, improving medical quality and promoting precision medical practice.

As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

Gout is a crystal-associated arthropathy caused by the deposition of monosodium urate crystals and is closely related to purine metabolic disorders and impaired uric acid excretion. It is clinically characterized by hyperuricemia, recurrent joint swelling and pain, and tophus formation. The disease course is divided into three stages: The hyperuricemia stage, acute attack stage, and chronic gouty arthritis stage. Modern medicine has reached a consensus on its pathology, but traditional Chinese medicine (TCM) lacks a systematic stage-specific understanding of gout pathogenesis and its underlying mechanisms, making it difficult to guide precise syndrome differentiation and treatment. By integrating classical TCM theory, clinical practice, and modern medical understanding, and drawing upon descriptions of Bi syndrome caused by endogenous dampness and turbidity in classical texts such as Huangdi Neijing·Ling Shu and Synopsis of the Golden Chamber, our team proposes the pathogenic concept of gout as ''endogenous dampness leading to Bi syndrome'' and the core pathogenesis of ''spleen deficiency with internal retention of dampness-turbidity''. We systematically elucidate the evolution of pathogenesis across different stages and corresponding therapeutic strategies. This study posits that metabolic byproducts such as urate fall under the category of ''endogenous pathogenic dampness-turbidity''. When genetic or dietary factors lead to metabolic abnormalities, it manifests as ''spleen deficiency with impaired transport and transformation'', resulting in ''internal retention of pathogenic dampness-turbidity''. When damp-turbidity stagnates in the blood vessels, serum uric acid levels rise. When it stagnates in the viscera and limbs, monosodium urate crystals deposit in the joints. Triggered by precipitating factors, this leads to gout attacks—the core pathological process of ''endogenous dampness leading to Bi syndrome''. Based on this theory, the stage-specific pathogenic characteristics of gout are proposed: The hyperuricemia stage is characterized by ''spleen deficiency with impaired transport and transformation, internal retention of pathogenic dampness-turbidity'', the acute attack stage is primarily marked by ''dampness-turbidity and static heat obstructing the limbs and joints'', while the chronic stage is defined by ''spleen deficiency with internal retention of pathogenic dampness-turbidity, intermingled with phlegm-stasis binding''. The treatment principle centers on ''strengthening the spleen and draining dampness'' throughout all stages. During the hyperuricemia stage, treatment focuses on ''strengthening the spleen, draining dampness, and eliminating turbidity''. In the acute attack stage, the treatment should "strengthen the spleen, drain dampness, clear heat, eliminate turbidity, alleviate swelling, and relieve pain''. In the chronic stage, the treatments emphasizes to ''strengthen the spleen, drain dampness, transform turbidity, clear heat, resolve phlegm, and activate blood circulation''. This approach has yielded favorable therapeutic outcomes in clinical practice. This theoretical system clarifies the nature of gout as ''spleen deficiency being the root, dampness-turbidity being the secondary manifestation'' and systematically analyzes its pathogenesis evolution process and characteristics. The constructed stage-based treatment protocol has been validated through clinical and basic research, providing systematic theoretical guidance and a practical framework for the precise TCM management of gout, thereby promoting the modernization of TCM pathogenesis theory related to gout.

ObjectiveBased on the clinical characteristics of chronic gouty arthritis (CGA) in both traditional Chinese and western medicine, this study aims to systematically evaluate the clinical concordance of existing CGA animal models, providing recommendations for establishing animal models that align with the pathological characteristics of CGA and the manifestations of traditional Chinese medicine syndromes. MethodsBy comprehensively retrieving Chinese and international databases such as China National Knowledge Infrastructure, Wanfang, VIP Chinese Science and Technology Periodical Database (VIP), and PubMed, all relevant literature on CGA animal models was collected. Based on the guidelines, the diagnostic criteria of both traditional Chinese and western medicine were summarized and organized. The evaluation indicators for the CGA model were constructed with reference to existing evaluation modes, and the CGA animal models were analyzed to systematically evaluate the clinical concordance of existing models. ResultsThe current methods used to construct CGA animal models mainly include monosodium urate crystal induction, high-protein diet induction (poultry lack urate oxidase), and high-fat diet combined with urate oxidase inhibitors and joint injection. Based on 11 pieces of included literature, the traditional Chinese and western medicine scoring data of each model were extracted, and the average scoring values of all models were ultimately calculated. The results show that the average clinical concordances of existing CGA animal models in both traditional Chinese and western medicine are 43.33% and 64.44%, respectively. Among them, the model with the highest clinical concordance rate is the one with a high-fat diet combined with potassium oxonate to induce hyperuricemia plus joint injection, achieving 83.33% clinical concordance in western medicine and 60% in traditional Chinese medicine. This model aligns well with the pathogenic characteristics and pathological changes of clinical CGA. ConclusionAlthough current CGA animal models can simulate some pathological characteristics of CGA, they struggle to comprehensively reflect the complex pathological processes of CGA and the characteristics of traditional Chinese medicine syndromes. Therefore, in the future, it is necessary to establish the CGA animal models that incorporate the clinical disease and syndrome characteristics of traditional Chinese and western medicine and formulate the uniform model evaluation criteria, providing more precise tools for CGA mechanism research and the development of traditional Chinese medicine.
