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 are systemic diseases with atherosclerosis as the pathological core, involving multiple vascular beds and target organs throughout the body. Due to their wide range and complexity, the traditional single-discipline prevention and treatment model struggles to meet the needs of systematic management, while clinical diagnosis often remains one-sided and insufficient, leading to delayed treatment. Literature reviews show that panvascular diseases involve a wide range of lesion sites, numerous influencing factors, and are prone to endangering life and health. It is urgent to construct a comprehensive and whole-course prevention and treatment management system, with vascular health as the goal and patients as the core. First, early screening and risk assessment should be conducted for high-risk groups. In terms of treatment decisions for patients, multi-disciplinary collaboration is needed to establish a scientific and standardized prevention and treatment path. Second, it is important to attach great importance to a people-centered approach, enhance patients' familiarity with the disease through cognitive intervention, and shift from passive treatment to active health care. Thirdly, it is needed to leverage the advantages of modern science and technology, promote the deep integration of artificial intelligence innovations and modern medicine, and help traditional diagnosis and treatment plans evolve towards precision, intelligence, and personalization. This will open up new paths for the modernization of the whole-course management of pan-vascular diseases. Fourth, efforts should be made to continue to carry forward and innovate the characteristics of traditional Chinese medicine, adhere to equal emphasis on modern and traditional medicine, promote complementary advantages and coordinated development of Chinese and Western medicine, and form a unique Chinese model for the whole-course management of panvascular diseases. Fifth, through the reintegration and redistribution of government, medical insurance, and medical resources, comprehensive talents in the broad vascular disciplines should be cultivated and an efficient hierarchical management model established, providing reference and guidance for the whole-course management of comprehensive diseases in the future.

Panvascular diseases refer to systemic vascular lesions with atherosclerosis as its common pathological basis, affecting the vascular networks of multiple organs such as the heart, brain, kidneys, limbs, and large arteries. This concept transcends the limitations of traditional classifications and promotes comprehensive vascular health management through multidisciplinary collaboration. Latent pathogenic factors play a critical role in the pathogenesis of panvascular diseases. They remain dormant within the body until finding an opportunity to manifest, which aligns closely with the characteristics of panvascular diseases, including their early covert progression and subsequent adverse vascular events. According to the ''latent pathogen'' theory, this article elucidates the pathogenesis of panvascular diseases from latent pathogen, vessel damage, and healthy Qi consumption. It posits that the disease onset involves a pathological process progressing from Qi to blood, with endothelial injury serving as the initiating factor. Disease progression encompasses changes from blood to vessels, with inflammatory responses accelerating the disease course. A comprehensive traditional Chinese medicine (TCM) based prevention and treatment system has been developed, dividing the disease course into three stages. In the early stage, pathogenic factors lurk in the vessels, primarily manifesting as abnormal lipid metabolism. In the middle stage, pathogenic factors evolve, leading to inflammatory cascade reactions. In the late stage, pathogenic factors become excessive while positive factors decline, resulting in abnormal energy metabolism. Three core therapeutic approaches-invigorating the spleen and resolving phlegm, activating blood and resolving stasis, and reinforcing healthy Qi and nourishing deficiency-have been established to address key pathological links. In conjunction with modern medical research, the mechanisms of these methods in regulating lipid metabolism, inhibiting inflammatory responses, and modulating energy metabolism to prevent and treat panvascular diseases are explained. It is anticipated that this theoretical framework will enrich the diagnostic and therapeutic thinking in TCM for panvascular diseases and provide a theoretical foundation for constructing TCM-characteristic prevention and treatment plans for panvascular diseases.

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.

ObjectiveTo explore the mechanism of Yinchenhao Tang regulating the tumor necrosis factor receptor superfamily member 6 (Fas)/cysteine protease-8 (Caspase-8)/cysteine protease-3 (Caspase-3) signaling pathway to inhibit hepatocyte apoptosis and improve cholestatic liver injury (CLI). MethodsAmong 48 Wistar rats,12 rats were randomly selected as the blank group,and the other rats were administered alpha-naphthalene isothiocyanate (ANIT) by gavage to induce a CLI model. The modeling rats were randomly divided into the model group, the ursodeoxycholic acid group(0.1 g·kg-1) and the Yinchenhao Tang group(9.23 g·kg-1),with 12 rats in each group. The rats in each group were given corresponding drugs by gavage for three consecutive days. The levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),gamma-glutamyl transpeptidase (γ-GT),total bilirubin (TBil) and total bile acid (TBA) in serum were detected. The levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in liver tissue were detected. The histopathological changes of the liver were observed by hematoxylin-eosin (HE) staining. The protein and mRNA expressions of Fas,Caspase-8,Caspase-3,B-cell lymphoma-2 (Bcl-2) associated X protein (Bax) and Bcl-2 in liver tissue were detected by Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with those in the blank group,the levels of ALT,AST,ALP,γ-GT,TBA and TBil in serum of the model group were significantly increased (P<0.01). The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly increased (P<0.01). The arrangement of hepatocytes was disordered,and inflammatory cell infiltration and bile duct epithelial cell proliferation were observed. The protein and mRNA expressions of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly increased(P<0.05,P<0.01),while the protein and mRNA expressions of Bcl-2 were significantly decreased (P<0.05,P<0.01). Compared with those in the model group,the levels of ALP,γ-GT,TBA and TBil in the serum of rats in the ursodeoxycholic acid group were significantly decreased. The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased(P<0.05,P<0.01). The protein and mRNA expressions of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly decreased (P<0.05,P<0.01),while the mRNA expression of Bcl-2 was significantly increased (P<0.05,). The levels of ALT,AST,γ-GT,TBA and TBil in the serum of rats in the Yinchenhao Tang group were significantly decreased (P<0.01). The levels and mRNA expressions of TNF-α and IL-1β in liver tissue were significantly decreased (P<0.05,P<0.01). The protein expression of Fas and Bax and the mRNA expression of Fas,Caspase-8,Caspase-3 and Bax in liver tissue were significantly decreased (P<0.05,P<0.01),while the protein and mRNA expression of Bcl-2 were significantly increased (P<0.05,P<0.01). Hepatocyte injury,inflammatory cell infiltration and proliferation of bile duct epithelial cells were reduced. ConclusionYinchenhao Tang can ameliorate CLI,and its mechanism may be related to inhibiting hepatocyte apoptosis mediated by the Fas/Caspase-8/Caspase-3 signaling pathway.

ObjectiveTo study the mechanism of Yinchenhao Tang on the improvement of cholestatic liver injury (CLI) by inhibiting toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear transcription factor-κB (NF-κB) pathway via regulating farnesol X receptor (FXR). MethodsA total of 40 Wistar male rats were randomly selected, with 10 as a blank group,and the remaining rats were subjected to the CLI model induced by alpha-naphthalene isothiocyanate (ANIT). After modeling,they were randomly divided into the model group, the ursodeoxycholic acid (0.1 g·kg-1) group and the Yinchenhao Tang (9.23 g·kg-1) group,with 10 animals in each group. Each administration group was given the corresponding drug by intragastric administration for three consecutive days. Alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),γ-glutamyl transpeptidase (γ-GT),total bile acid (TBA),total bilirubin (TBil) and direct bilirubin (DBil) levels in serum were detected. Tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β),and interleukin-6 (IL-6) levels in liver tissue were detected. Real-time PCR was used to detect the mRNA expression of FXR,TLR4,MyD88,NF-κB,F4/80,TNF-α,IL-1β and IL-6 in liver tissue. Western blot was used to detect protein expression of FXR,TLR4,MyD88 and NF-κB in liver tissue. The histopathological changes of the liver were observed by hematoxylin-eosin (HE) staining. ResultsCompared with those in the blank group,ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the model group were significantly increased (P<0.01). The levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were significantly increased (P<0.01),and the mRNA and protein expressions of FXR in liver tissue were decreased (P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 were obviously increased (P<0.05,P<0.01). Hepatic histopathology showed inflammatory cell infiltration and proliferative changes of bile duct epithelial cells. Compared with those in the model group,ALT,ALP,γ-GT,TBA,TBil and DBil levels in serum of rats in the ursodeoxycholic acid group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.05,P<0.01). The mRNA and protein expressions of TLR4,MyD88 and NF-κB and the mRNA expression of F4/80 in liver tissue were obviously decreased (P<0.05,P<0.01). ALT,AST,ALP,γ-GT,TBA,TBil and DBil levels in the serum of rats in the Yinchenhao Tang group were obviously decreased (P<0.05,P<0.01),and the levels and mRNA expression of TNF-α,IL-1β and IL-6 in liver tissue were obviously decreased (P<0.01). The mRNA and protein expressions of FXR in liver tissue were significantly increased,and the mRNA expressions of TLR4,MyD88,NF-κB,and F4/80, as well as the protein expressions of TLR4 and NF-κB were obviously decreased (P<0.05,P<0.01). The inflammatory cell infiltration of liver tissue and the proliferation of bile duct epithelial cells decreased. ConclusionYinchenhao Tang has an obvious protective effect on CLI,and its mechanism may be related to regulating FXR to inhibit TLR4/MyD88/NF-κB pathway-mediated inflammatory response.

ObjectiveTo explore the mechanism by which Yinchenhao Tang intervenes in α-naphthylisothiocyanate (ANIT)-induced cholestatic liver injury by regulating the Takeda G-protein-coupled receptor 5(TGR5)/NOD-like receptor protein 3(NLRP3)/cysteine aspartate-specific protease-1 (Caspase-1) pyroptosis signaling pathway. MethodsForty male Wistar rats were randomly assigned into blank, model, ursodeoxycholic acid, and Yinchenhao Tang groups. Except the blank group, other groups were treated with ANIT dissolved in olive oil for the modeling of cholestatic liver injury. Ursodeoxycholic acid (0.1 g·kg-1) and Yinchenhao Tang (9.23 g·kg-1) were administered by gavage. The blank group and the model group were administrated with the same amount of pure water, once a day for 3 days. The blood and liver tissue samples were collected, and the serum levels of liver function indicators were measured by an automatic biochemical analyzer. Hematoxylin-eosin staining was employed to observe the pathological changes of the liver. The levels of interleukin (IL)-1β and IL-18 in the liver tissue were determined by ELISA. The mRNA levels of IL-1β, IL-18, TGR5, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1, and GSDMD in the liver tissue were assessed by Real-time PCR. The protein levels of TGR5, NLRP3, ASC, Caspase-1, and GSDMD in the liver tissue were determined by Western blot. ResultsCompared with the blank group, the model group showed elevated levels of alanine amino-transferase (ALT), aspartate transferase (AST), alkaline phosphatase (ALP), total bile acid (TBA), and total bilirubin (TBil) in the serum (P<0.01), inflammatory cell infiltration, hepatocyte swelling, and bile duct epithelial cell proliferation in the liver, raised levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA and protein levels of TGR5 (P<0.01), up-regulated mRNA levels of IL-18 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), IL-1β (P<0.05), and NLRP3 (P<0.05), and up-regulated protein levels of NLRP3 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), and GSDMD (P<0.05). Compared with the model group, the ursodeoxycholic acid group showed declined levels of AST (P<0.01), TBA (P<0.01), TBil (P<0.01), and ALT (P<0.05) in the serum, lowered levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA levels of NLRP3 (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), IL-1β (P<0.05), IL-18 (P<0.05), and ASC (P<0.05), up-regulated mRNA and protein levels of TGR5 (P<0.05), and down-regulated protein levels of NLRP3, ASC, Caspase-1, and GSDMD (P<0.05). Compared with the model group, the Yinchenhao Tang group showed lowered levels of ALT, AST, ALP, TBA, and TBil in the serum (P<0.01), declined levels of IL-1β and IL-18 in the liver tissue (P<0.01), down-regulated mRNA levels of IL-1β (P<0.01), NLRP3 (P<0.01), ASC (P<0.01), Caspase-1 (P<0.01), GSDMD (P<0.01), and IL-18 (P<0.05), up-regulated mRNA and protein levels of TGR5 (P<0.01), and down-regulated protein levels of Caspase-1 and GSDMD (P<0.05). The liver tissue of the administration groups showed reduced infiltration of inflammatory cells, reduced swelling of hepatocytes, and alleviated proliferation of bile duct epithelial cells. ConclusionYinchenhao Tang can ameliorate ANIT-induced cholestatic liver injury by regulating the hepatocyte pyroptosis mediated by the TGR5/NLRP3/Caspase-1 signaling pathway.
