Pan vascular disease （PVD） is a systemic vascular disorder that has become the leading cause of death among the Chinese residents， and there is currently a lack of effective systemic treatment options. Clinical practice has found that the traditional Chinese medicine （TCM） method of kidney tonification can effectively intervene in PVD and target key pathological mechanisms of PVD recognized in Western medicine. Accordingly， this paper conducts research from the following three aspects： First， it clarifies that immune dysregulation， metabolic disorders， and genetic susceptibility constitute the core pathological mechanisms of PVD in Western medicine. Typical pathological manifestations include progressive vascular endothelial injury， lipid deposition， and plaque formation， ultimately leading to multi-organ damage and dysfunction. PVD activates pathways such as the NOD-like receptor thermal protein domain-associated protein 3 （NLRP3） inflammasome， triggering immune dysregulation； it also induces disorders of mitochondrial energy metabolism， water-salt metabolism， and hormonal metabolism， synergizing with genetic susceptibility factors （e.g.， apolipoprotein E gene） to accelerate vascular homeostasis imbalance. Second， this study analyzes the intrinsic relationship between the TCM theory of "kidney deficiency" and the "immune-metabolic-genetic" axis， revealing the theoretical basis for kidney tonification in intervening PVD. The kidney stores essence， governs bones， and produces marrow， which is related to the generation and differentiation of immune cells. It regulates Qi transformation and governs water， overseeing material and energy metabolism. The kidney is the root of congenital essence and governs reproduction， closely related to genetic mechanisms. Third， by integrating modern clinical research， this study elaborates on the unique advantages and clinical value of kidney tonification in targeting the "immune-metabolic-genetic" axis of heart， brain， and kidney organs. Traditional kidney-tonifying formulas and their active ingredients improve immune-inflammatory responses， enhance material and energy metabolism homeostasis， and modulate epigenetic pathways through multiple pathways， targeting various pathways to intervene in PVD. This study systematically elucidates the scientific connotation of kidney tonification in treating PVD， providing theoretical support and practical guidance for integrated TCM-Western medicine approaches and contributing to innovation and improvement in diagnostic and treatment strategies for PVD.

Panvascular diseases represent systemic vascular disorders characterized by atherosclerosis as their core pathological feature. Their incidence rates continue to rise， posing significant challenges for clinical management. Based on Traditional Chinese Medicine （TCM） theory of ''positive deficiency phlegm stasis''， this study delved into the pivotal role of mitochondrial homeostasis dysregulation in the pathogenesis and progression of pan-vascular diseases， along with its intrinsic connection to TCM pathogenesis. Mitochondrial homeostasis dysregulation pervades the entire course of these diseases， with mitochondrial oxidative stress serving as the initiating factor. Excessive reactive oxygen species （ROS） trigger endothelial dysfunction， lipid accumulation， and inflammatory initiation. Additionally， the imbalance between mitochondrial autophagy and apoptosis constitutes a pivotal link in disease progression. Excessive or insufficient autophagy may lead to the accumulation of damaged mitochondria and excessive cellular apoptosis， thereby promoting plaque instability. Furthermore， mitochondrial metabolic reprogramming impairs energy supply and function in vascular wall cells， hindering subsequent vascular repair. These pathological processes constitute the microscopic manifestation of the core pathogenesis， which is characterized by ''the intermingle of phlegm and stasis and the deficiency of healthy Qi''. Specifically， the endogenous phlegm-turbidity drives mitochondrial oxidative stress injuries， the mutual entanglement of phlegm and stasis induces an imbalance between mitochondrial autophagy and apoptosis， while deficiency of healthy Qi propels mitochondrial energy metabolism disorders and reprogramming. In view of this， this study proposed to employ phlegm-resolving and turbidity-clearing methods to mitigate mitochondrial oxidative stress injuries， phlegm-resolving and blood-activating methods to regulate mitochondrial autophagy and apoptosis， and spleen-tonifying and kidney-nourishing methods to modulate mitochondrial metabolic reprogramming. This approach can prevent and treat panvascular diseases by multi-target regulation of mitochondrial homeostasis， providing a theoretical framework and therapeutic strategies for the prevention and treatment of panvascular diseases through integrated Chinese and Western medicine.

BACKGROUND: Osteoarthritis (OA) is a prevalent joint disorder that significantly impairs quality of life among elderly individuals because of chronic pain and physical disability. As the global burden of OA continues to rise, novel therapeutic strategies are urgently needed. Kaempferide (KA), a flavonoid derived from traditional Chinese herbal medicine, is known for its anti-inflammatory properties. However, the effect of KA on the progression of OA has not been well investigated. This study aimed to explore the therapeutic potential of KA in an OA model and investigate the underlying mechanisms via transcriptomic sequencing. METHODS: An in vitro OA model was established using SW1353 cells treated with interleukin-1 beta (IL-1β) and different concentrations of KA (30, 60, or 90 μmol/L) for 24 h. The anti-inflammatory effects of KA were assessed using quantitative real-time polymerase chain reaction (qRT-PCR), enzyme-linked immunosorbent assay (ELISA), and Western blotting. In vivo , a papain-induced OA rat model was used to evaluate the therapeutic effects of KA through histological and behavioral analyses. Transcriptomic sequencing was performed to explore the differentially expressed genes (DEGs) and related signaling pathways. Statistical analysis was conducted using one-way analysis of variance. RESULTS: KA significantly increased cell viability in the OA chondrocyte model and downregulated the expression of inflammatory cytokines and cartilage degradation markers, with the greatest reduction observed at 90 μmol/L. In vivo , KA treatment mitigated cartilage degradation and improved gait behavior in OA rats. Transcriptomic analysis revealed substantial modulation of DEGs, implicating the hypoxia-inducible factor-1 (HIF-1) signaling pathway as a key mechanism. Further blocking and rescue experiments revealed that KA regulated key molecules within the HIF-1 pathway, specifically interferon-gamma (IFN-γ) and hypoxia-inducible factor 1-alpha (HIF-1α), confirming their critical roles in mediating the therapeutic effects of KA. CONCLUSION KA inhibited the progression of OA by targeting the HIF-1 signaling pathway, reducing inflammation, and cartilage degradation.
