Microvascular diseases (MVD) can affect multiple systems in the body and are important factors in the occurrence and development of cardiovascular, cerebrovascular, renal, and metabolic diseases, as well as the aging process. It is proposed that the key pathogenesis of MVD is "cold constraint in sanjiao (三焦)". Based on the theory of cold pathogen, and by integrating the common and local pathologies of sanjiao, a treatment principle of promoting blood circulation and warming is established. A basic prescription for promoting blood circulation and warming is formulated, with modifications based on the specific pathogenesis of the upper, middle, and lower jiao (焦). For the upper jiao, cold constraint primarily involves the failure of the clear yang to rise and qi and blood stagnation, for which treatment should focus on diffusing and unblocking the heart and the lung, opening constraint and vibrating yang, commonly adding Shengxian Decoction (升陷汤) for warming and dispersing to assist in diffusion and dissipation, and using Guizhi Decoction (桂枝汤)-series formulas to harmonize ying-wei (营卫) and open the striae and interstices; both formulas can invigorate yang qi. For the middle jiao, cold constraint primarily involves the dysfunction of the central yang and internal accumulation of turbid pathogen, for which treatment should focus on harmonizing the spleen and stomach, warming and reinforcing yang; formulas such as Sini Powder (四逆散), Zhishi Xiaopi Pill (枳实消痞丸), and Banxia Xiexin Decoction (半夏泻心汤) can be used to restore qi flow, promote digestion, and balance cold and heat; Shengyang Yiwei Decoction (升阳益胃汤) can further enhance raising the clear and directing the turbid downward, expelling cold and removing dampness. For the lower jiao, cold constraint primarily involves damage to the original yang and dysfunction of qi transformation, for which the treatment should focus on tonifying original qi and reinforcing the foundation, as well as promoting diuresis and supporting yang; depending on the degree of deficiency and the presence of internal water accumulation, formulas like Jingui Shenqi Pill (金匮肾气丸), Fuzi Decoction (附子汤), and Zhenwu Decoction (真武汤) can be used. Based on the theory of cold constraint, the principle of promoting blood circulation and warming method runs through the differentiation and treatment of MVD. By further incorporating the pathological characteristics of sanjiao, flexible treatment strategies can be developed, which helps deepen the understanding of the disease's etiology and pathogenesis, while broadening clinical diagnostic and therapeutic approaches.

Angiogenesis, as a core mechanism for maintaining tissue perfusion and repairing ischemic injury, plays a crucial role in ischemic diseases such as coronary heart disease and peripheral arterial disease. Traditional Chinese medicine(TCM), with its advantages of multi-target and synergistic regulation, provides a unique perspective for therapeutic angiogenesis. Based on this, this article intends to delve into the synergistic effects of key signaling pathways, including vascular endothelial growth factor(VEGF)/VEGF receptor(VEGFR), Notch, phosphoinositide 3-kinase/ protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR), and angiopoietin/endothelial TEK tyrosine kinase(Ang/Tie2), and elucidate the driving mechanisms of endothelial cell metabolic reprogramming and exosome-mediated intercellular communication within this process. Based on existing literature, it summarizes the microenvironment-dependent and bidirectional regulatory characteristics of natural active components of TCM(such as terpenes, tanshinones, and flavonoids) on angiogenesis. Furthermore, it systematically discusses how classical TCM formulas achieve blood vessel formation and functional maturation by protecting the neurovascular units, recruiting pericytes, and remodeling the microenvironment. Current evidence highlights the advantages of multi-target synergy and temporal regulation in TCM, but also reveals challenges such as high heterogeneity and a lack of functional evaluations and high-quality clinical trials. Future efforts should integrate multi-omics to decipher network mechanisms, optimize formula compatibility, and conduct multicenter studies to promote the development of innovative preparations. This review highlights the academic value of TCM in angiogenesis, provides an evidence base for treating ischemic diseases, and supports multidisciplinary integration and innovation.

Artificial intelligence (AI) is gradually being applied in the field of decision-making support for the daily care of the older adults with disabilities. However, due to their limited cognitive functions, information asymmetry with medical staff and technical parties, and a certain degree of emotional deprivation, the older adults with disabilities are in a structurally vulnerable position. Against this background, several ethical dilemmas arise when AI technology intervenes in care decision-making. First, the informed consent process is difficult to genuinely implement. Second, algorithms based on average models tend to ignore individual differences, leading to “de-personalization” of services. Third, over-reliance on technology may further weaken humanistic care, thereby undermining the individual dignity of the older adults with disabilities. Fourth, in the care decision-making involving the joint participation of the older adults with disabilities, caregivers, medical teams, and AI systems, the boundaries of responsibility among all parties remain unclear, making it difficult to assign accountability when adverse outcomes occur. Drawing on the theories of vulnerability ethics, interactive ethics, and care ethics, this paper proposes a “vulnerability-interaction-care” path and put forward three-tiered countermeasures. The first was baseline safeguards, preventing the exploitation of the vulnerability of the older adults with disabilities and their caregivers, and requiring further safeguards for their dignity. The second was process protection, enhancing transparency and accountability within the human-machine collaboration framework, as well as establishing a multi-party consultation mechanism. The third was capacity empowerment, improving the subjectivity of the older adults with disabilities through age-appropriate interaction, structured expression of intentions, and caregiver participation.

ObjectiveTo explore the mechanism by which the ethanol extract of Epimedium brevicornu (EEBM) intervenes in mesenchymal adipose-derived stem cells (ADSCs) to delay aging in castrated rats. MethodsForty-five 3-month-old SPF female SD rats were ovariectomized and randomly divided into model group, ADSCs treatment group, and ADSCs groups treated with low, medium, and high concentrations of EEBM (1, 50, 100 μg·L-1), referred to as the AE low, medium, and high concentration groups, with 9 rats in each group. After tail vein injection of 200 μL of the corresponding stem cell suspension, aging-related indicators including cyclin-dependent kinase inhibitor (p21), tumor suppressor gene (p53), interleukin-6 (IL-6), interleukin-8 (IL-8), superoxide dismutase (SOD), malondialdehyde (MDA), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cysteine-aspartic acid protease-3 (Caspase-3), and lipofuscin were measured using enzyme-linked immunosorbent assay (ELISA) and Western blot. ResultsCompared with the model group, the IL-6 content in the AE low, medium, and high concentration groups was significantly decreased (P<0.05). Lipofuscin, MDA, and IL-8 levels in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.01), while SOD content was significantly increased (P<0.05, P<0.01). Compared with the ADSCs treatment group, lipofuscin and IL-8 levels in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01). The MDA content was significantly decreased in the AE medium concentration group (P<0.01). Compared with the model group, protein levels of p21, p53, Bax, and Caspase-3 in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), while the Bcl-2 protein level was significantly increased (P<0.01). Compared with the ADSCs treatment group, protein levels of p21, p53, Bax, and Caspase-3 in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), and the Bcl-2 protein level in the AE low concentration group was significantly increased (P<0.01). ConclusionThe results of this experiment show that EEBM-treated ADSCs or ADSCs may delay aging in castrated rats by inhibiting cell apoptosis, reducing cell cycle inhibitors and pro-inflammatory factors, enhancing antioxidant capacity, and reducing oxidative reactions. Moreover, EEBM-treated ADSCs demonstrate stronger anti-aging effects than ADSCs alone. This study provides experimental evidence supporting the clinical use of EEBM to intervene in ADSCs and delay aging.

Objective:To understand the pathogenic composition and epidemiological characteristics of febrile respiratory syndrome (FRS) in elderly people aged 60 and above in China, and to provide a reference basis for the scientific and precise prevention and control of FRS in the elderly.Methods:Based on FRS cases surveillance data from information management system of National Technical Platform for Infectious Disease Surveillance, National Science and Technology Major Project of China, the surveillance pathogens included 8 viruses, including influenza virus (IFV), respiratory syncytial virus (RSV), adenovirus (HAdV), parainfluenza virus (HPIV), metapneumovirus (HMPV), coronavirus (HCoV), bocavirus and rhinovirus (HRV); 7 bacterias, namely Streptococcus pneumoniae ( S.pneumoniae), Staphylococcus aureus ( S.aureus), Klebsiella pneumoniae ( K.pneumoniae), Pseudomonas aeruginosa ( P.aeruginosa), Group A Streptococcus ( GAS), Haemophilus influenzae ( H.influenzae) and Legionella pneumophila ( L. pneumophila), in addition to Chlamydia pneumoniae ( C. pneumoniae) and Mycoplasma pneumoniae ( M. pneumoniae). A descriptive epidemiological approach was used to analyze the pathogenic composition and major epidemiological characteristics of FRS cases aged 60 years and older nationwide from 2009 to 2021. Results:The predominant viruses of FRS cases aged≥60 years accounted for 87.93% of the pathogen spectrum in China, including IFV (42.42%), HRV (16.71%), HPIV (11.53%), HCoV (9.52%), and RSV (7.75%), while the pathogen spectrum of the major bacteria accounted for 94.60%, including S. pneumoniae (25.71%), P. aeruginosa (24.97%), K. pneumoniae (22.47%), H. influenzae (12.23%), and S. aureus (9.22%). Influenza viruses have always been at the top of the viral pathogen spectrum, and P. aeruginosa, K. pneumoniae and S. pneumoniae, ranked high in the bacterial pathogen spectrum. Among them, the proportions of HRV, HPIV, RSV, K. pneumoniae, and H. influenzae fluctuated and increased during the 13 years of observation. The positive rate of any pathogen in FRS cases was higher in out patient emergencies (32.83%) than in hospitalized cases (27.26%) ( χ2 =125.89, P<0.001). The positive rate of IFV was higher in cases aged 60-74 years (13.66%). The positive rate of P. aeruginosa and K. pneumoniae were higher in cases aged ≥90 years (10.71%, 9.40%) and in northern regions (8.32%, 7.30%). The positive rate of any pathogen in FRS cases was higher in winter (33.82%) than in other seasons ( χ2=212.03, P<0.001). The positive rate of IFV and HRV were higher in winter (22.87%) and autumn (5.98%) and the positive rate of P.aeruginosa (8.11%) and K.pneumoniae (8.30%) were higher in summer. Conclusions:IFV, HRV, HPIV, S. pneumoniae, P. aeruginosa and K. pneumoniae were respectively the top three pathogens in the viral and bacterial pathogen spectrum of FRS cases aged 60 years and above in China from 2009 to 2021, and the positive rate of these main pathogens showed differences between age groups, seasons, and geographic regions. In the future, the dynamic surveillance of various pathogens in the elderly with respiratory tract infections should be continuously strengthened.

Primary open angle glaucoma(POAG)is the most common type of glaucoma, with common causes including variations in trabecular tissue and increased venous pressure. POAG has a certain genetic tendency, and POAG with an autosomal dominant inheritance pattern is mainly caused by single gene mutations. Studies have found that the pathogenesis of POAG may be related to key pathogenic genes(MYOC, OPTN, WDR 36), as well as mitochondrial dysfunction, oxidative stress, and epigenetic regulation. At present, the clinical treatment options for POAG mainly include enhancing trabecular meshwork function, inhibiting aqueous humor production, neuroprotection and regeneration of retinal ganglion cells, and applying gene editing technology, all of which have achieved certain results. However, there is no unified research on the relationship between the occurrence of POAG and genes, as well as treatment plans. The article explores new targets and treatment strategies for POAG gene therapy by analyzing the role of genes in the pathogenesis of POAG, aiming to provide reference for clinical treatment of this disease.
