Chinese Journal of Experimental Traditional Medical Formulae 2026;32(3):183-190
ObjectiveIn recent years, with the deepening trend of population aging in China, the incidence of age-related macular degeneration (AMD) has been rising. Wet age-related macular degeneration (wAMD) is a type of advanced AMD that can cause severe vision loss. Based on the clinical disease-syndrome characteristics of wAMD, this study reviewed and analyzed existing wAMD animal models, including the animals used, modeling methods, and the advantages and disadvantages of each model, aiming to provide references for the establishment and study of wAMD models integrating disease and syndrome. MethodsLiterature on wAMD-related animal models was retrieved from China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP, and PubMed. Relevant indicators were collected and analyzed, and model characteristics were quantified and evaluated according to the diagnostic criteria of diseases and syndromes in both traditional Chinese medicine (TCM) and Western medicine. ResultsCurrently, the alignment of wAMD models with Western medicine clinical syndromes mainly reflects the characteristics of macular neovascularization (MNV) and fundus changes, with limited observation of visual function. For TCM, scoring mainly focuses on ocular syndromes, while systemic syndromes are insufficiently observed, which is inadequate to fully reflect the complexity of wAMD pathogenesis and manifestations. Among the main models, alignment with Western medicine clinical syndromes is relatively high. Laser photocoagulation-induced models are the most commonly used and show the highest alignment, and their correspondence with the TCM syndrome of “spleen deficiency and dampness retention” is relatively high. ConclusionCurrent models generally show moderate alignment with clinical disease-syndrome characteristics in both TCM and Western medicine, especially with TCM syndromes, where alignment is low. This limits the development and study of models integrating disease and syndrome. Future research should further explore other TCM syndrome types and compound syndromes to establish wAMD animal models with higher alignment with TCM.

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.

Retinitis pigmentosa (RP) is the most common hereditary blinding eye disease in clinical practice, with the pathogenesis remaining unclear. Patients experience progressive apoptosis of retinal photoreceptor cells, accompanied by degeneration of retinal pigment epithelium (RPE) cells. Current Western medical treatments mainly focus on gene therapy and stem cell transplantation, showing limited efficacy. In contrast, clinical observations have confirmed the therapeutic effects of traditional Chinese medicine (TCM) treatments. Establishing an RP animal model that aligns with the diagnostic features of both TCM and Western medicine could help combine the strengths of both approaches, thereby broadening the treatment options for RP. This study categorizes and summarizes the existing RP animal models in terms of classification, types, inheritance patterns, and alignment with clinical manifestations. It is found that current RP models are primarily derived from natural animal models such as RD mice and RCS rats, transgenic animal models like RPE-65 knockout mice and rhodopsin gene knockout mice, and chemically induced models such as those created by monochromatic light exposure or N-ethyl-N-nitrosourea (ENU) administration. These three categories of models focus more on detecting RP-related histopathological, molecular biological, and cellular immunological indicators, but offer limited observation of the overall characteristics of the disease and lack insight into syndrome differentiation. Although RP is a congenital genetic disease, its progression is influenced by acquired factors such as environment, constitution, emotions, and care. Current models do not fully capture the characteristics of this disease. Therefore, establishing an RP animal model based on the diagnostic features of both TCM and Western medicine will have significant implications for future experimental and clinical research.

ObjectiveRetinal vein occlusion (RVO) is the second most common vascular disease leading to vision loss. Since its pathogenesis remains unclear, current Western medical treatments primarily target complications such as macular edema and neovascularization. The main therapeutic approaches include intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents or corticosteroids, laser photocoagulation, and pars plana vitrectomy. However, these treatments cannot fully reverse disease progression or structural damage. Traditional Chinese medicine (TCM) has unique advantages in the clinical diagnosis and treatment of RVO, and integrated Chinese and Western medicine approaches may offer better clinical outcomes. This study, based on the clinical manifestations of RVO, systematically reviews the existing literature and evaluates the alignment of current RVO animal models with clinical manifestations. The aim is to identify the characteristics and limitations of existing models and provide recommendations and prospects for developing RVO animal models featuring the combination of disease and syndrome. MethodsDatabases including CNKI, Wanfang Data, PubMed, and Web of Science were searched with the keywords of "retinal vein occlusion" and "animal model". Model characteristics were assessed based on the diagnostic criteria for diseases and syndromes in both TCM and Western medicine. The alignment of each model with clinical manifestations was analyzed and evaluated. ResultsThe available RVO models were primarily established via methods such as laser photocoagulation, photodynamic therapy, diathermy, intravitreal drug injection, and mechanical modeling. These models demonstrated moderate overall alignment with clinical manifestations, mainly reflecting disease characteristics. However, they generally lack representation of TCM syndrome features. ConclusionExisting RVO models are predominantly based on Western medicine and lack TCM syndrome features. Western medical treatments for RVO have certain limitations, while syndrome differentiation and treatment in TCM offer potential advantages. Future research should focus on developing disease-syndrome integrated animal models that incorporate both pathological features and TCM syndrome characteristics. This approach will enhance the design of RVO models and facilitate both basic and clinical research, which make it a scientifically valuable and necessary endeavor.

ObjectiveTo construct a scale for the diagnosis of chronic atrophic gastritis (CAG) with turbid toxin accumulating in the stomach. MethodsFirst, a research group was established to construct the scale framework. Relevant literature of CAG with syndrome of turbid toxin accumulating in the stomach was searched in CNKI, Wanfang Database (WF), and VIP Database (CQVIP) from April 1, 2003 to April 1, 2023, and items were preliminarily selected after standardization of terms. Through clinical investigation, the discrete trend method, correlation coefficient method, Cronbach's coefficient method, and factor analysis method were used to screen symptom items, and the frequency method was used to screen signs, tongue coating, and pulse conditions. Three rounds of Delphi expert consultation were conducted to determine the items of the scale. The weight of each item was obtained by the analytic hierarchy process. ResultsA total of 49 articles were included, and 45 items were obtained after primary screening, including 28 symptoms, 2 signs, 10 tongue coatings, and 5 pulse conditions. After clinical investigation, 15 symptoms were retained, and 8 signs and pulse conditions of tongue coating were retained. The positive coefficients of experts in three rounds of Delphi expert consultation were 100%, 96.67%, and 100%, respectively. The expert authority coefficients were 0.86, 0.87, and 0.87, respectively, and the coordination coefficients were 0.18, 0.25, and 0.30. After core group discussion, Delphi method investigation, and AHP weight assignment, the diagnostic scale items of CAG with turbid toxin accumulating in stomach syndrome were finally established, namely, dark red or purplish tongue proper with yellow greasy (or dry) coating (30 points), epigastric stuffiness and fullness or pain (15 points), sticky and unsmooth defecation (10 points), taste disturbance (sticky mouth, fetid breath, bitter taste, 7 points), heartburn or acid regurgitation (6 points), dizziness and clouding (5 points), general heaviness and fatigue (5 points), slippery, string‑slippery, or slippery‑rapid pulse (5 points), dysuria (or yellow or deep yellow urine, 4 points), poor appetite (4 points), dull complexion (3 points), sticky, greasy, and fetid secretions (3 points), and poor sleep (3 points). ConclusionBased on the establishment, screening, confirmation, and weighting of an item pool, combined with subjective and objective approaches as well as qualitative and quantitative methods, a diagnostic scale for CAG with the syndrome of turbid toxin accumulating in the stomach was successfully constructed.

ObjectiveTo investigate the effects of prostaglandin E2 (PGE2) microinjection into the median preoptic nucleus (MnPO) on core body temperature in female mice, and to clarify its underlying mechanism. MethodsMicroinjection cannula were implanted into the MnPO of female mice using stereotaxic surgery.Subsequently, a multi-channel temperature acquisition system was used to simultaneously monitor rectal and brown adipose tissue (BAT) temperatures before and after intra-MnPO injections of different reagents.To investigate the thermoregulatory effects of the microinjection of PGE2 into the MnPO, 12 female C57BL/6 mice were randomly divided into a saline group (n=6) and a PGE2 group (n=6), which were injected with 0.1 μL saline and PGE2 (2.8 mmol/L), respectively.To determine whether E-series prostaglandin receptor (EP)1, EP3, and EP4 receptors mediate the thermoregulatory effects of PGE2, 15 female C57BL/6 mice were randomly divided into 3 groups (n=5 per group).Mice in each group first received an injection of 0.1 μL PGE2 (2.8 mmol/L) into the MnPO. After their body temperature returned to baseline levels, they were subsequently injected with a mixture of either EP1, EP3 or EP4 antagonist (ant) (20 mmol/L) + PGE2 (2.8 mmol/L). ResultsCompared with baseline level, the rectal temperature (P<0.01) and BAT temperature (P<0.001) of female mice both increased significantly after microinjection of PGE2 into the MnPO.Compared with the saline group, the increases in rectal temperature (P<0.001) and BAT temperature (P<0.000 1) were significantly greater in the PGE2 group of mice.Furthermore, following the injection of PGE2 into MnPO, the increase in BAT temperature was found to be significantly greater than that in rectal temperature in mice (P<0.001).Compared to the administration of PGE2 alone, co-injection of an EP3 ant + PGE2 into the MnPO of mice resulted in a significantly smaller increase in both rectal temperature (P<0.001) and BAT temperature (P<0.001).In contrast, the increases in rectal and BAT temperatures following MnPO injection of either EP1 ant + PGE2 or EP4 ant + PGE2 were not statistically significant (P>0.05). ConclusionInjection of PGE2 into the MnPO elevates BAT and core body temperature in female mice via the EP3 receptor.
