Abstract The health literacy level among the elderly in China remains at a low level. The 14th Five-Year Plan for Healthy Aging clearly points out that health literacy promotion projects should be implemented to improve the health literacy level among the elderly. The health literacy promotion strategies for the elderly require individual, social, policy and environmental supports. This article reviewed four types of health literacy promotion strategies for the elderly, including social strategies, lecture-based health education strategies, new media-based health communication strategies and environmental strategies. It also proposed that health education institutions, communities and other parties should work together, take advantage of digital technology and internet, and take various measures simultaneously to improve the health literacy of the elderly.

ObjectiveThis study sought to investigate the impact of exosomes derived from LoVo cells (LoVo-Exos) in colorectal cancer (CRC) on tumor angiogenesis, as well as to elucidate the potential molecular mechanisms underlying their pro-angiogenic effects. MethodsLoVo-Exos were isolated via ultracentrifugation, and their internalization into recipient human umbilical vein endothelial cells (HUVECs) was visualized using confocal microscopy. The influence of LoVo-Exos on angiogenesis was assessed through an in vitro tube formation assay. Additionally, the pro-angiogenic effects of LoVo-Exos were evaluated in vivo using a matrix gluing assay in mice. To investigate the molecular mechanisms through which LoVo-Exos facilitate angiogenesis, Western blot analysis was employed to examine the transfer of pEGFR by LoVo-Exos into recipient cells. Both Western blot and ELISA were utilized to assess the expression levels of key signaling proteins within the EGFR-ERK pathway, as well as the expression of downstream angiogenic core molecules. Furthermore, the impact of EGFR knockdown and ERK inhibitor treatment on angiogenesis was evaluated, with subsequent analysis of the expression of downstream angiogenic core molecules following these interventions. ResultsConfocal microscopy demonstrated the internalization of LoVo-Exos into HUVECs. In vitro angiogenesis assays further indicated that LoVo-Exos significantly enhanced the formation of tubular structures in HUVECs. Additionally, macroscopic examination of subcutaneous matrix plug formation in mice revealed a substantial increase in vascular-like structures within the matrix plugs following the administration of LoVo-Exos, compared to the PBS control group. Hematoxylin and eosin (HE) staining revealed the presence of erythrocyte-filled microvessels within the matrix plugs combined with LoVo-Exos. Furthermore, immunohistochemical analysis demonstrated the expression of the endothelial cell marker CD31 in these matrix plugs. The presence of CD31-positive cells in the LoVo-Exos-treated matrix plugs was associated with a significant enhancement in the formation of luminal structures. These findings suggest that LoVo-Exos facilitate the in vivo development of vascular-like structures. Subsequent investigations demonstrated that LoVo-Exos facilitated the delivery of pEGFR to HUVEC, thereby enhancing angiogenesis. Conversely, LoVo-Exos with EGFR knockdown exhibited a diminished capacity to promote angiogenesis, an effect that was further attenuated by the ERK phosphorylation inhibitor U0126. Western blot analysis assessing the activation of the EGFR-ERK signaling pathway in HUVEC indicated that LoVo-Exos augmented angiogenesis through the activation of this pathway. Furthermore, analysis of the impact of LoVo-Exos on the expression of downstream angiogenic core molecules revealed an increase in interleukin-8 (IL-8) secretion in HUVEC. The enhancement observed was diminished in LoVo-Exos following EGFR knockdown, and this reduction was counteracted by the ERK phosphorylation inhibitor U0126. ConclusionThe underlying mechanism may involve the delivery of pEGFR in LoVo-Exos to HUVECs, leading to increased IL-8 secretion via the EGFR-ERK signaling pathway, thereby enhancing the angiogenic potential of HUVECs. This finding may offer new insights into the mechanisms underlying cancer metastasis.

Tangye Jingfa Tu is an important content in the ancient book Fuxingjue from Dunhuang， implying the fundamental principles of formula compatibility in traditional Chinese medicine （TCM）. Our research group has delved into nearly 200 formulas （both classical and contemporary formulas） recorded in the Fangjixue under the theoretical framework of the deficiency or excess syndrome of five Zang-organs together with the reinforcing and reducing effects of Chinese medicinal materials of five flavors. We have initially elucidated the essential principles of the correspondence between formulas and syndromes， revealing the deep-level logic of medicinal material selection and compatibility， thus enriching the understanding about the core characteristics and essence of the diseases and syndromes targeted by formulas. The lunar year of 2024 is Jia Chen year. The formula recorded in Sanyin Jiyi Bingzheng Fanglun for treating the epidemic diseases characterized by excessive earth， prevalent dampness and wetness， and invasion of pathogenic factors into the kidney water in Jia Chen year is Fuzi Shanzhuyutang. Therefore， elucidating the compatibility principle of Fuzi Shanzhuyutang is of great significance for clinical prescription and medication modification in Jia Chen year. According to the Tangye Jingfa Tu theory on the deficiency or excess of syndrome of five Zang-organs and the reinforcing and reducing effects of Chinese medicinal materials of five flavors， this article dissects Fuzi Shanzhuyutang regarding the etiology and pathogenesis of the main indications， as well as the five-element properties and efficacy characteristics of Chinese medicinal materials constituting this formula. It explains the compatibility principles of Fuzi Shanzhuyutang and puts forward suggestions for modifying the formula to address different indications， providing a reference for guiding clinical syndrome differentiation and treatment.

ObjectiveAccording to the theory of medicinal properties in traditional Chinese medicine （TCM）， Tangye Jingfa Tu， implying that all tonic prescriptions should primarily feature sweetness. However， the "Chart of the Classic Methods of Decoction Therapy" recorded in Mnemonic Aids for Medical Practice （Fuxingjue） proposes that each of the Zangfu organs has a corresponding tonifying flavor， i.e.， pungent for the liver， salty for the heart， sweet for the spleen， sour for the lungs， and bitter for the kidneys. Therefore， deficiency syndromes of different organs should be primarily addressed with specific medicinal flavors. This study applies this theoretical framework to analyze the formulation and compatibility principles and efficacy positioning of commonly used TCM tonic prescriptions， providing a reference for differentiated clinical medication. MethodsA database of tonic prescriptions was established based on the textbook Science of Prescriptions. Excel software was used to separately calculate the number of medicinal types， frequency of use， flavors， and proportional composition of the prescriptions. The prescriptions were categorized to determine their compatibility structures and functional characteristics. ResultsA total of 60 prescriptions were included， classified into six categories， involving 110 medicinal types with 469 instances of use. From the perspective of the "Chart of the Classic Methods of Decoction Therapy"， different tonic prescriptions exhibit distinct dominant medicinal flavors and organ associations. Specifically， 15 Qi-tonifying prescriptions primarily adopted a "sweet flavor" to tonify the spleen. Nine blood-tonifying prescriptions primarily adopted a "pungent-salty flavor" to tonify the liver and heart. Seven Qi-and-blood-tonifying prescriptions primarily featured a "sweet-pungent flavor" to tonify the spleen and liver. Nineteen Yin-tonifying prescriptions primarily adopted a "bitter-sour flavor" to tonify the kidneys and lungs. Seven Yang-tonifying prescriptions primarily featured a "pungent-bitter flavor" to tonify the liver and kidneys. Three Yin-and-Yang-tonifying prescriptions primarily featured a "bitter-pungent-sweet flavor" to tonify the kidneys， liver， and spleen. ConclusionThe "Chart of the Classic Methods of Decoction Therapy" clearly illustrates the formulation and compatibility principles and key differences among various tonic prescriptions， indicating that not all tonic prescriptions are predominantly sweet in flavor. This provides new insights for the clinical modification and application of tonic prescriptions.

ObjectiveChinese patent medicines for cardiovascular and cerebrovascular diseases are diverse and complex in their efficacy. The traditional classification method based on efficacy categories has certain limitations and cannot meet the clinical needs for individualized drug selection and variety comparison. This article， based on the formulation compatibility analysis technology of "Tangye Jingfa Tu"， clarifies the composition and efficacy characteristics of common Chinese patent medicines used for cardiovascular and cerebrovascular diseases， providing support for the precise selection of these medicines. MethodsFifty-six representative Chinese patent medicines， covering all the efficacy subcategories of "stasis-resolving agents" in the National Basic Medical Insurance， Work Injury Insurance， and Maternity Insurance Drug Catalogue （2023） （more than 50% of the total）， were selected for the study. Within the knowledge system of "Tangye Jingfa Tu"， the compatibility structure of herbal flavors and the proportion structure of herbal quantities for each Chinese patent medicine were determined. The correlation between these structures and the efficacy categories was analyzed to identify the similarities and differences among the selected Chinese patent medicines. Additionally， the efficacy was reclassified and compared according to the theoretical framework of tonifying and purging methods of five Zang organs in the "Tangye Jingfa Tu". ResultsThe representative Chinese patent medicines included in the analysis were Shexiang Baoxin pills， Danshen tablets， Qili Qiangxin capsules， Breviscapine tablets， etc.， covering all the efficacy subcategories of "stasis-resolving agents". Among the 56 representative Chinese patent medicines， salty flavor was the most common （48）， followed by pungent （33）， and sweet （26）. According to the dominant herbal flavor， salty flavor was the most common （37）， followed by pungent （9）， and sour （5）. According to the dominant herbal quantity， salty flavor was the most common （27）， followed by sour （7）， and pungent （5）. Furthermore， Chinese patent medicines with different efficacy subtypes showed different flavor characteristics. For example， most Qi-invigorating and blood-activating agents contained sweet drugs for tonifying the spleen （9/10）， most Qi-moving and blood-activating agents contained pungent drugs for tonifying the liver （7/8）， and all kidney-invigorating and blood-activating agents contained bitter drugs for tonifying the kidneys （6/6）. However， the efficacy classification of individual medicines did not always align with the compatibility characteristics of their formulas， as seen with Dengyin Naotong capsules. ConclusionThe formulations of Chinese patent medicines for cardiovascular and cerebrovascular diseases predominantly feature salty， sour， and pungent flavors， which largely conform to the therapeutic principles of "nourishing the heart with salt and soothing the heart with sour" and the liver-heart， heart-spleen mother-child treatment relationship shown in the "Tangye Jingfa Tu". Using the "Tangye Jingfa Tu" framework to conduct research on the structure and efficacy characteristics of Chinese patent medicines is objective and effective.

The "theory of Zangqi method" in Huangdi Neijing the "Tangye Jingfa picture" in Dunhuang's posthumous book Fuxingjue both contain the relationship between the five medicinal tastes and the reinforcing-reducing treatment of the five Zang organs. This article made a systematic comparative analysis of the two methods from the aspects of narrative methods， specific content， mathematical logic， clinical experience， and real treatment effect. From the perspective of narrative methods， they both adopted the expression structure of three medicinal tastes corresponding to one organ， which were respectively described as tonic， laxative， and urgent tastes， with the same way of thinking and the narrative frame shared. From the perspective of reinforcing-reducing content， out of a total of 15 attributes related to the corresponding tonic， laxative， and urgent tastes of the five organs involved in the two methods， there were seven inconsistencies between the two methods. In terms of medicinal taste distribution， the "Tangye Jingfa Tu" presented the order of "liver， heart， spleen， lung， and kidney"， Whether tonic， laxative， or transforming tastes， they were all pungent， salty， sweet， sour， or bitter. However， the "theory of Zangqi method" showed no such pattern. From the perspective of mathematical modeling analysis， the distribution of medicinal tastes in the "Tangye Jingfa Tu" conformed to the mathematical logic of the outer product of a five-dimensional space vector， while the "theory of Zangqi method" had no such law. From the perspective of clinical experience， the effect of removing the heart-fire with a bitter taste in the "Tangye Jingfa Tu" was more consistent with the clinical cognition of clearing heat and detoxification effects of traditional Chinese medicine （TCM） with a sweet taste in the "theory of Zangqi method". From the perspective of understanding prescriptions and solving prescriptions， the combination and compatibility principle of 160 common classical prescriptions in the Formulas of Traditional Chinese Medicine can be analyzed by using the "Tangye Jingfa Tu". Therefore， the authors believed that the relationship between the five medicinal tastes and the reinforcing-reducing treatment of the five zang organs in the Fuxingjue was more rigorous and logical， in line with clinical empirical cognition than the relevant records in the Yellow Emperor's Canon of Medicine.
