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.

N-acetyl-p-aminophenol (APAP) is an antipyretic analgesic commonly used in clinical practice, and APAP overdose can cause severe liver injury and even death. In recent years, the incidence rate of APAP-induced liver injury (AILI) tends to increase, and it has become the second most common cause of liver transplantation worldwide. Autophagy is a highly conserved catabolic process that removes unwanted cytosolic proteins and organelles through lysosomal degradation to achieve the metabolic needs of cells themselves and the renewal of organelles. A large number of studies have shown that autophagy plays a key role in the pathophysiology of AILI, involving the mechanisms such as APAP protein conjugates, oxidative stress, JNK activation, mitochondrial dysfunction, inflammatory response and apoptosis. This article elaborates on the biological mechanism of autophagy in AILI, in order to provide a theoretical basis for the treatment of AILI and the development of autophagy regulators.

ObjectiveTo investigate the mechanism of modified Si Junzitang and Shashen Maidong Tang [Yiqi Yangyin Jiedu prescription (YQYYJD)] in enhancing the sensitivity of cisplatin in epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI)-resistant lung adenocarcinoma cells based on aerobic glycolysis. MethodsThe effects of different concentrations of YQYYJD (0, 2, 3, 4, 5, 6, 7, 8 g·L-1) and cisplatin (0, 3, 6, 9, 12, 15, 18, 21, 24, 27 mg·L-1) on the proliferation and activity of PC9/GR cells were detected by the cell counting kit-8 (CCK-8) assay after 24 hours of intervention. The half-maximal inhibitory concentration (IC50) for PC9/GR cells was calculated to determine the concentrations used in subsequent experiments. PC9/GR cells were divided into blank group (complete medium), YQYYJD group (5 g·L-1), cisplatin group (12 mg·L-1), and combined group (YQYYJD 5 g·L-1 + cisplatin 12 mg·L-1). After 24 hours of intervention, cell viability was measured using CCK-8 assay. Cell proliferation was assessed by colony formation assay, and cell migration was evaluated by scratch and Transwell assays. Glucose consumption, lactate production, and adenosine triphosphate (ATP) levels were measured by colorimetric assays. The expression levels of glycolysis-related proteins, including hexokinase 2 (HK2), phosphofructokinase P (PFKP), pyruvate kinase M2 (PKM2), lactate dehydrogenase A (LDHA), glucose transporter 1 (GLUT1), and monocarboxylate transporter 4 (MCT4), were determined by Western blot. ResultsBoth YQYYJD and cisplatin inhibited the viability of PC9/GR cells in a concentration-dependent manner. The IC50 of PC9/GR cells for YQYYJD and cisplatin were 5.15 g·L-1 and 12.91 mg·L-1, respectively. In terms of cell proliferation, compared with the blank group, the cell survival rate and the number of colonies formed in the YQYYJD group, cisplatin group, and combined group were significantly decreased (P<0.01). Compared with the YQYYJD and cisplatin groups, the combined group showed a further significant reduction in cell survival rate and colony formation (P<0.01). In terms of cell migration, compared with the blank group, the cell migration rate and the number of cells passing through the Transwell membrane in the YQYYJD group, cisplatin group, and combined group were significantly decreased (P<0.01). Compared with the YQYYJD and cisplatin groups, the combined group exhibited a further significant reduction in cell migration rate and the number of cells passing through the Transwell membrane (P<0.01). In terms of glycolysis, compared with the blank group, glucose consumption, lactate production, and ATP levels in the YQYYJD group, cisplatin group, and combined group were significantly decreased (P<0.01). Compared with the YQYYJD and cisplatin groups, the combined group showed a further significant reduction in glucose consumption, lactate production, and ATP levels (P<0.05). Compared with the blank group, the protein expression levels of HK2, PFKP, PKM2, and LDHA in the YQYYJD, cisplatin, and combined groups were significantly decreased (P<0.01). The combined group showed a further significant reduction in the expression levels of these proteins compared with the YQYYJD and cisplatin groups (P<0.01). No significant differences were observed in the protein expression levels of GLUT1 and MCT4 among the groups. ConclusionYQYYJD can synergistically inhibit the proliferation and migration of PC9/GR cells and enhance their sensitivity to cisplatin. The mechanism may be related to the downregulation of the expression of glycolysis-related rate-limiting enzymes, including HK2, PFKP, PKM2, and LDHA, thereby inhibiting glycolysis.

ObjectiveTo explore the possible mechanism of Qishao Tongbi Capsule (芪芍通痹胶囊, QTC) in the treatment of intervertebral disc degeneration (IDD). MethodsSeventy-five rats were randomly divided into control group, model group, low-dose QTC group, high-dose QTC group, high-dose QTC +agonist group, with 15 rats in each group. Except for the control group, all other groups were subjected to a fibrous ring puncture to prepare an IDD model. After modeling, rats in low-dose QTC group and high-dose QTC group were given QTC at doses of 0.2 and 0.8 g/(kg·d) by gavage, respectively. Rats in high-dose QTC+ agonist group was given QTC at 0.8 g/(kg·d) and SKL2001 solution at 10 mg/(kg·d) by gavage. The control group and model group were given 10 ml/(kg·d) distilled water by gavage. All treatments were given once a day for 4 consecutive weeks. After treatment, X-ray and magnetic resonance imaging (MRI) were used to detect IDD degree. Hematoxylin-eosin (HE) staining and Safranin O-Fast Green staining were used to observe the morphological changes of the intervertebral disc tissue. Immunohistochemical staining was performed to examine the levels of proteoglycan, type Ⅱ collagen (COL Ⅱ), and matrix metalloproteinase-3 (MMP-3) in the intervertebral disc tissue. Western blotting was used to detect the extracellular matrix (ECM)-related proteins (proteoglycan, COL Ⅱ, MMP-3, MMP-9, MMP-13), aging-related proteins (P53, P21, P16), apoptosis related proteins, including B-cell lymphoma/leukemia 2 (BCL-2), BCL-2 related X protein (BAX), Cleaved Caspase-3, and Wnt/β-catenin pathway related proteins such as Wnt3a, glycogen synthase kinase-3β (GSK-3β) and β-catenin in the intervertebral disc nucleus pulposus (NP) tissue. Reverse Transcription Quantitative Polymerase Chain Reaction (RT-qPCR) was used to assess the mRNA expression of Wnt3a, GSK-3β, and β-catenin in intervertebral disc tissue. ResultsCompared with the model group, rats in the low-dose QTC group and high-dose QTC group exhibited improved DHI, decreased Pfirmann grading, and alleviated IDD. The structural integrity of the NP and annulus fibrosus increased, and the number of the NP increased. The levels of proteoglycan, COL Ⅱ, BCL-2 and GSK-3β increased, while the levels of MMP-3, MMP-9, MMP-13, P53, P21, P16, BAX, Cleaved Caspase-3, Wnt3a and β-catenin protein decreased. The mRNA expression of Wnt3a and β-catenin mRNA decreased, while GSK-3β mRNA expression increased (P<0.05). Compared with the low-dose QTC group, the high-dose QTC group showed further improvements in DHI, decrease in Pfirrmann grading (P<0.05), and greater alleviation of IDD. The structural integrity of NP and annulus fibrosus was further enhanced, and the number of NP cells further increased. The levels of proteoglycan, COL Ⅱ, BCL-2 and GSK-3β were higher, while the levels of MMP-3, MMP-9, MMP-13, P53, P21, P16, BAX, Cleaved Caspase-3, Wnt3a and β-catenin were lower. The mRNA expression of Wnt3a and β-catenin decreased, while GSK-3β mRNA expression increased (P<0.05). Compared with the high-dose QTC group, the high-dose QTC +agonist group showed a decrease of DHI, an increase of Pfirmann grading (P<0.05), significant aggravation of IDD, reduction in structural integrity of the NP and annulus fibrosus, a decrease of NP cell count, lower levels of proteoglycan, COL Ⅱ, BCL-2 and GSK-3β, and higher levels of MMP-3, MMP-9, MMP-13, P53, P21, P16, BAX and Cleaved Caspase-3. Additionally, GSK-3β mRNA expression decreased (P<0.05). ConclusionQTC can inhibit NP cell aging, apoptosis, and ECM degradation in IDD rats, and its therapeutic effect may be mediated through the inhibition of the Wnt/β-catenin pathway.

Objective To explore the impact of national volume-based procurement policies on the use of medicines in treatment of benign prostatic hyperplasia (BPH) and provide data support for the rational clinical use of medicines in BPH treatment. Methods Data on the use of BPH treatment medications from 2019 to 2023 were extracted from the Chinese Medicine Economic Information Network (CMEI), covering 892 hospitals (including 645 tertiary hospitals and 247 secondary hospitals). The changes in various indicators, including the consumption sum, Defined daily doses (DDDs), Defined daily dose cost (DDDc), and the ranking ratio (B/A) of these drugs were analyzed and compared. Results From 2019 to 2023, due to the influence of relevant policies, the overall consumption sums of medicines used in the sample hospitals in BPH treatment showed a trend of decreasing first and then rising steadily. The DDDs showed an overall upward trend, while the DDDc demonstrated a gradual decline. Tamsulosin and finasteride consistently ranked first and second in DDDs. The B/A value for tamsulosin was significantly higher than that of other BPH treatment medications. Conclusion The implementation of national centralized drug volume-based procurement policies and other policies from 2019 to 2023 had effectively reduced the economic burden of patients with benign prostatic hyperplasia. Tamsulosin and finasteride, which had the highest B/A in the two categories of α-blockers and 5α-reductase inhibitors, dominated the market for BPH treatment. The clinical use of BPH treatment medications was relatively rational.
