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.

3.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 effect of bone morphogenetic protein 3 (BMP3) on the expression of inflammatory factors and joint damage in adjuvant arthritis (AA) induced by Freund′s complete adjuvant (FCA) in rats. MethodsThe AIA model was established in SD rats by intradermal injection of FCA into the toes of the left hind limb, and BMP3 overexpressing adenovirus (Ad-BMP3) or control adenovirus (Ad-NC) was injected in situ into the knee joint cavity on day 8 after modeling. Subsequently, HE staining was used to observe the histopathological changes in the synovium, immunohistochemistry was used to detect the expression of BMP3 in the synovium, and ELISA was used to analyze the expression levels of IL-6, IL-1β and TNF-α in the serum. Primary fibroblast-like synoviocytes (FLS) were isolated from AIA rats, the expression of BMP3 in FLS was knocked down or overexpressed, and Western blot and qRT-PCR were used to detect the expression levels of BMP3 and inflammatory factors in FLS. ResultsHE staining confirmed the successful establishment of the AIA model. Compared with normal rats, AIA rats showed decreased BMP3 expression in synovial tissue. Knockdown of BMP3 promoted the protein expression of inflammatory factors (IL-6, IL-1β, IL-17A, TNF-α) and the mRNA expression of chemokines [C-C motif chemokine ligand 2 (CCL2), C-C motif chemokine ligand 3 (CCL3), Vascular Cell Adhesion Molecule-1 (VCAM-1)] in FLS. In contrast, overexpression of BMP3 suppressed the expression of these inflammatory factors and chemokines. Intra-articular injection of BMP3-overexpressing adenovirus in AIA rats upregulated BMP3 expression in synovial tissue and inhibited synovial inflammation and bone erosion. ConclusionBMP3 suppresses the production of inflammatory factors and chemokines in FLS, thereby alleviating synovial hyperplasia and bone erosion in arthritis.

OBJECTIVE To investigate the improvement effects and its mechanism of Bazheng powder on chronic urinary tract infection (CUTI) induced by Escherichia coli in rats. METHODS The rats were divided into normal control group, model group, levofloxacin group (45 mg/kg) and Bazheng powder group (4.95 g/kg), with 10 rats in each group. Except for the normal control group, other groups were administered an intravesical injection of Escherichia coli suspension (1×10⁸ cfu/mL) via the urethra to establish CUTI model; at the same time, rats in each group were administered the corresponding medicinal solution or water by gavage once a day for 4 consecutive weeks. After the last medication, blood routine tests (white blood cell count and lymphocyte percentage), the levels of serum inflammatory factors [interleukin-1β (IL-1β), IL-6, IL-8, tumor necrosis factor-α (TNF-α)], and immune indicators [CD4, CD8, secretory immunoglobulin A (SIgA)], renal function indicators [cystatin C (Cys-C), α1- microglobulin (α1-MG), urea and creatinine] were all determined; the pathological changes in renal and bladder tissues in rats were observed. The protein expressions of Toll-like receptor 4 (TLR4), nuclear factor-κB (NF-κB), and nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3) in rat bladder tissues were detected. RESULTS Compared with the normal control group, the levels of IL-1β, IL-6, IL-8, TNF-α, CD8, Cys-C, α1-MG, urea and creatinine in serum, as well as the protein expressions of TLR4, NF-κB and NLRP3 in bladder tissues, were significantly elevated in the model group (P<0.05). Conversely, the levels of CD4 and SIgA were significantly decreased (P<0.05). Pathological changes, such as extensive infiltration of inflammatory cells, were observed in both renal and bladder tissues. Compared with the model group, the above quantitative indicators in the Bazheng powder group were significantly improved (P<0.05), with no obvious inflammatory lesions observed in either renal or bladder tissues. CONCLUSIONS Bazheng powder can alleviate inflammatory reaction and improve the immune function of CUTI rats, and its mechanism may be related to the inhibition of TLR4/NF-κB/ NLRP3 signaling pathway.

BACKGROUND:
The transcription factor POU2F1 regulates the expression levels of microRNAs in neoplasia. However, the miR-29b1/a cluster modulated by POU2F1 in gastric cancer (GC) remains unknown.
METHODS:
Gene expression in GC cells was evaluated using reverse-transcription polymerase chain reaction (PCR), western blotting, immunohistochemistry, and RNA in situ hybridization. Co-immunoprecipitation was performed to evaluate protein interactions. Transwell migration and invasion assays were performed to investigate the biological behavior of GC cells. MiR-29b1/a cluster promoter analysis and luciferase activity assay for the 3'-UTR study were performed in GC cells. In vivo tumor metastasis was evaluated in nude mice.
RESULTS:
POU2F1 is overexpressed in GC cell lines and binds to the miR-29b1/a cluster promoter. POU2F1 is upregulated, whereas mature miR-29b-3p and miR-29a-3p are downregulated in GC tissues. POU2F1 promotes GC metastasis by inhibiting miR-29b-3p or miR-29a-3p expression in vitro and in vivo . Furthermore, PIK3R1 and/or PIK3R3 are direct targets of miR-29b-3p and/or miR-29a-3p , and the ectopic expression of PIK3R1 or PIK3R3 reverses the suppressive effect of mature miR-29b-3p and/or miR-29a-3p on GC cell metastasis and invasion. Additionally, the interaction of PIK3R1 with PIK3R3 promotes migration and invasion, and miR-29b-3p , miR-29a-3p , PIK3R1 , and PIK3R3 regulate migration and invasion via the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway in GC cells. In addition, POU2F1 , PIK3R1 , and PIK3R3 expression levels negatively correlated with miR-29b-3p and miR-29a-3p expression levels in GC tissue samples.
CONCLUSIONS
The POU2F1 - miR-29b-3p / miR-29a-3p-PIK3R1 / PIK3R1 signaling axis regulates tumor progression and may be a promising therapeutic target for GC.
