Aging has emerged as a cutting edge and hotspot in global life science field， with anti-aging and geriatric disease prevention and treatment becoming critical issues urgently demanding solutions in international medical communities. In the face of the challenge of accelerating global population aging， in-depth exploration of aging mechanisms and the development of effective intervention strategies hold significant scientific and clinical value. This study supported by the national key research and development program of China， employed the essence-Qi-spirit theory of Qiluo doctrine as its guiding framework， focusing on the key scientific issue of the core traditional Chinese pathogenesis of aging， namely "depletion of kidney essence， deficiency of primordial Qi， and impairment of body and spirit". The treatment principle of "tonifying the kidney to replenish essence， harmonizing Yin and Yang， warming and invigorating primordial Qi， and nourishing the body and spirit" was established. Centered on holistic aging， systemic aging， and aging-related diseases， the research integrated multidisciplinary research approaches to construct multi-modal aging models and a multi-dimensional evaluation system， and it utilized multi-omics technologies to deeply analyze aging mechanisms. By systematically reviewing historical kidney-tonifying and anti-aging formulas and combining big data with artificial intelligence technologies， an information database of anti-aging traditional Chinese medicine substance was developed to reveal the differences and synergistic effects of various treatment methods and formulas on anti-aging. Based on this treatment method， the research integrated two millennia of kidney-tonifying medicinal experience to develop the innovative anti-aging traditional Chinese medicine， namely Bazhi Bushen capsules. It was validated that this capsule can delay holistic and systemic aging through multiple targets and mechanisms， thereby elucidating the scientific connotation of the essence-Qi-spirit theory of Qiluo doctrine in guiding anti-aging research from multiple dimensions and providing robust support for leveraging the advantages of traditional Chinese medicine to occupy the commanding heights of international anti-aging research.

This paper explores the transmission patterns of "qi collaterals-qi airways-blood （vessels） collaterals" in chronic obstructive pulmonary disease （COPD） based on the syndrome differentiation and treatment theory of lung collateral disease. Lung qi collaterals carry original qi， pectoral qi and defensive qi， primarily responsible for regulation and nourishment. The lung's airway serves as the pathway for the ascending and descending of qi. The lung's blood （vessel） collaterals circulate ying （营）-blood to nourish and infiltrate. Those three work synergistically to complete the core function of the lung， including governing qi， controlling respiration， and facilitating "qi exchange and blood transformation"， with their functions converging in the "minute collateral-sweat pores". The occurrence and development of COPD follow the transmission pattern of "qi collaterals-qi airways-blood （vessels） collaterals". Initially， the condition is rooted in qi stagnation caused by deficiency （pectoral qi deficiency and sink）， which leads to airway obstruction and difficulty in ventilation. Ultimately， disorder of qi affects the function of blood， resulting in a state of vessel collaterals obstruction characterized as "phlegm complicated by blood stasis hindering qi causes disease" .

BACKGROUND:Mammary stem cells are vital for the development and homeostasis of mammary gland tissue.The occurrence of breast cancer has a close relationship with the mammary stem cells.Recent studies have shown that Hopx,as an important transcriptional regulator of morphogenesis and cell differentiation,has been confirmed to be expressed in a variety of adult stem cells such as nerves,intestines,hair follicles and lungs.However,its role in mammary stem cells has not been reported so far.OBJECTIVE:To investigate whether Hopx expression marks mammary stem cells.METHODS:(1) Female Hopx-LacZ transgenic mice aged 8 weeks were selected to detect the background expression of Hopx in breast tissue by β-galactosidase staining.(2) Female wild-type mice at 4,6,and 8 weeks of age and 14.5 days of gestation were selected for whole-tissue magenta staining and K14 and K8 immunofluorescence staining,respectively.(3) Female Hopx-CreERT2;Rosa26LacZ transgenic mice aged 8 weeks and 17.5 days of gestation were selected and stained with breast β-galactosidase.(4) The 4-week-old female Hopx-CreERT2;Rosa26LacZ transgenic mice were selected.The Cre/loxp system was activated by intraperitoneal injection of tamoxifen (once every other day,three times),and breast β-galactosidase staining was performed 4 weeks after injection.The 8-week-old female Hopx-CreERT2;Rosa26LacZ transgenic mice were selected.The Cre/loxp system was activated by intraperitoneal injection of tamoxifen (once every other day,three times),and breast β-galactosidase staining was performed 4 and 10 weeks after the last injection.(5) Female Hopx-CreERT2;Rosa26LacZ transgenic mice aged 8 weeks were selected.The Cre/loxp system was activated by intraperitoneal injection of tamoxifen (once every other day,three times).Hopx-CreERT2;Rosa26LacZ transgenic mice were pregnant 2 weeks after injection.The mammary tissue of mice at 17.5 days of the first pregnancy and 17.5 days of the third pregnancy was stained with β-galactosidase.RESULTS AND CONCLUSION:(1) The results of β-galactosidase staining showed that the mammary ducts of Hopx-LacZ transgenic mice at 8 weeks of age did contain Hopx-positive cells and were located in the basal epithelia,with a small number.(2) Whole-mount staining of mammary glands and immunofluorescence staining results exhibited that the mammary glands of mice had different characteristics with corresponding developmental stages such as puberty,maturity,and pregnancy,and underwent a series of complex epithelial remodeling processes.(3) The results of β-galactosylase staining showed that Hopx-labeled positive cells in the mammary duct of Hopx-CreERT2;Rosa26LacZ transgenic mice at 17.5 days of gestation increased compared with female Hopx-CreERT2;Rosa26LacZ transgenic mice at 8 weeks of age.(4) The results of β-galactosylase staining showed that the Hopx-labeled positive cells in the mammary glands of 4-and 8-week-old female Hopx-CreERT2;Rosa26LacZ transgenic mice after tamoxifen injection were located in the basal epithelium with a small number.(5) The results of β-galactosidase staining showed that Hopx-labeled positive cells in the mammary glands of mice at 17.5 days of the first and third gestation were located in the basal epithelia around the alveoli,and the number of Hopx-labeled positive cells at 17.5 days of the third gestation was more.(6) In conclusion,Hopx reporter-marked basal epithelial cells belong to dormant mammary stem cells,which are responsible for the growth of the mammary glands during pregnancy and contribute to acinar formation.

In the Qing Dynasty， YE Gui proposed the pathogenesis of "chronic diseases entering the collaterals" as a rule for collateral diseases. In the context of viral respiratory diseases， the course of the disease is considered a relative concept. A systematic review of historical literature reveals that "new pathogens" belong to the category of "new diseases". It identifies that "new diseases" include types where the pathogenic qi initially invades without harming the righteous qi， where old diseases relapse while not being completely cured， and where chronic diseases suddenly flare up. These are not limited to exogenous diseases. "New pathogens" refer to diseases caused by the invasion of warm-heat pathogens， the six excesses， and epidemic qi， differing from the modern traditional Chinese medicine term "new warm diseases" related to latent heat diseases. Based on the "collaterals-meridians-collaterals" transformation pathway described in The Inner Canon of Yellow Emperor （《黄帝内经》） and the pathogenesis of external pathogens entering the zang-fu organs via the meridians as described in Treatise on Febrile Disease （《伤寒论》）， as well as the external warm diseases' transformation rule explained by YE Gui from the perspective of collaterals， the concept of "new pathogen invading the collaterals" is proposed. Further analysis indicates that this concept aligns with the transmission and pathogenesis patterns of viral respiratory diseases. The treatment method of "clearing epidemic pathogens， detoxifying， and spreading the lung to relieve heat" is considered important for the prevention and control of viral respiratory infectious diseases.

ObjectiveExploring the formula rules of commonly used traditional Chinese medicines（TCMs） for epidemic treatment from the Qin and Han dynasties to the Qing dynasty through data mining， providing reference for the prevention and control of contemporary epidemics. MethodsThe articles on epidemic treatment in the electronic database of Chinese Medical Code V5.0 were systematically searched， and the contents such as source， dynasty， author， diagnosis， formula name， therapeutic method and efficacy， and composition of medicines from each article that met the inclusion criteria were extracted. Then， an Excel standardized database was established， and Python programs were used for data mining to summarize the frequency of commonly used medicines and perform hierarchical cluster analysis， Pearson correlation analysis， and association rule analysis. ResultsA total of 1 595 formulas were included， involving 558 TCMs. The efficacy of these medicines could be classified into two categories， namely， expeling pathogenic factors and reinforcing healthy Qi. According to the frequency deconstruction analysis， high-frequency medicines were mainly detoxification， Fu-organ dredging， aromatization and promoting blood circulation， followed by the medicines with the effect of treating the lungs， such as clearing the lungs and resolving phlegm， clearing heat and purging the lungs， relieving cough and asthma， and purging the lungs and relieving asthma. And the proportions of acrid-warm herbs and acrid-cold herbs varied in different periods. Hierarchical clustering and correlation analysis both suggested TCMs for expeling pathogenic factors and reinforcing healthy Qi often formed stable combinations with high association degrees. Association rule analysis showed that the core acrid-warm herb was mainly Ephedrae Herba， and the core acrid-cold herb was mainly Forsythiae Fructus， resulting in the core formulas of Maxing Shigantang and Yinqiaosan. ConclusionThroughout history， the prevention and control of epidemics have been based on the principle of "preserving healthy Qi and avoiding toxic Qi"， focusing on the treatment of the causes and characteristics of epidemics through detoxification， Fu-organ dredging， and aromatization， emphasizing the use of Rhei Radix et Rhizoma and other herbs to dredge Fu-organ， eliminate toxins and pathogens， and playing the role of actively intervene with symptomatic medication. And based on the external manifestations of the body's struggle between evil and righteousness， diagnose and treatment according to syndrome differentiation was performed.

Diabetic retinopathy（DR）， as one of the most common and serious microvascular complications of diabetes mellitus， seriously threatens human health， and belongs to "Xiaoke eye diseases" in traditional Chinese medicine（TCM）， which has been richly experienced by medical practitioners through the ages， but is mostly recorded in a piecemeal manner and has not been systematically researched. This disease is featured by long course and repeated attack， and is refractory， which belongs to the research category of "persistent illness entering collaterals". Systematic establishment of TCM collateral disease theory for guiding prevention and treatment of DR has important clinical value. On the basis of close correlation between tertiary collaterals at the terminal of collaterals and capillaries and microcirculation， the concept of "tertiary collaterals-microvascular" is proposed. It is pointed out that DR falls within the scope of "tertiary collaterals-microvascular" diseases， and presents four types of micro-pathological characteristics， including stasis， insufficiency， growth and bleeding of tertiary collaterals. It is concluded that "deficiency of both Qi and Yin" is the basic pathogenesis of DR， and "blood stasis and collateral obstruction" is the important pathogenesis and key factor. Thus， the treatment method of "dispersing blood stasis， dredging collateral， tonifying Qi and Yin， stopping hemorrhage and improving eyesight" is determined， and the formula of Tongluo Mingmu capsules is developed. The article tightly focuses on the pathological changes such as stasis， growth， insufficiency and bleeding of collaterals， addresses both symptoms and root causes， and plays a synergistic role of both dispersing stasis and stopping bleeding. In this way， it can realize the purpose of tonifying Qi and Yin to replenish the essence， dispersing stasis and dredging collaterals to meet the requirement， as well as stopping hemorrhage and improving eyesight to deal with changes. Fundamental researches demonstrate that Tongluo Mingmu capsules has synergy effects of protecting both retinal capillaries and retinal cells. Phase-Ⅲ clinical trial of new drug has proven definite clinical efficacy and good safety， which provides a new drug choice for enhancing clinical effect of DR， and further supports the scientific value of Luobing theory in preventing and treating DR and other clinically significant diseases.

This study summarizes Professor Qin Zhenhua's clinical experience in treating cutaneous pruritus using a modified self-prescribed formula,Yinqiao Xingzi Decoction.Following the viewpoints from the classical Chinese medical literature and after years of clinical practice,Professor Qin proposes that the onset of cutaneous pruritus is often associated with the attack of exogenous pathogens,disharmony of qi and blood,or debility due to prolonged illness.The disease primarily involves the skin,with the fundamental pathogenesis of pathogens stagnating in the muscular superficies.Clinically,the treatment is frequently conducted from the perspective of fire-heat syndrome,and the therapeutic methods of clearing heat and removing toxins,releasing muscles and dispersing pathogens from the superficies,and dispelling wind to relieve itching are utilized.The approaches aim to cool heat in the blood,expel pathogens from the muscular layer,eliminate heat for stopping itching,and extinguish wind for calming the skin.The basic prescription,Yinqiao Xingzi Decoction(composed of Lonicerae Japonicae Flos,Forsythiae Fructus,Armeniacae Semen Amarum,Arnebiae Radix,Tribuli Fructus,Dictamni Cortex,Kochiae Fructus,and Glycyrrhizae Radix et Rhizoma),is used by modification depending on the predominance of pathogenic factors of wind,heat,dryness,or dampness-toxins,and according to the various syndromes like blood-heat,yin deficiency,or qi-blood deficiency.Yinqiao Xingzi Decoction is applicable to cutaneous pruritus with the most of clinical common syndrome types,but it is unsuitable for cases caused by yang deficiency or qi stagnation with blood stasis.

Chronic obstructive pulmonary disease(COPD)is a common disease with a high global incidence and mortality rate.It is charac-terized by chronic inflammation and structural airway obstruction that is not fully reversible,leading to shortness of breath caused by air trapping and increased physical exertion.Over the past few decades,the incidence of COPD has continued to rise.Although commonly used therapeutic agents,such as glucocorticoids and bronchodilators,have demonstrated significant symptomatic relief,they primarily target symptoms rather than halting disease progression.Therefore,further research is needed to better understand the underlying mechanisms of COPD and to develop novel therapeutic strategies for its prevention and management.Early studies on the pathogenesis of COPD primarily focused on airway epithelial cell injury,while relatively less attention was given to pulmonary vascular endothelial cells(PVECs).However,recent evidence indicates that COPD is not only an airway and systemic inflammatory disorder but also a vascular disease,with PVECs playing a critical role in its pathogenesis.PVECs are among the main cellular targets damaged in COPD and are involved in mediating its initiation and progression.In this review,we summarize emerging evidence that highlights the close association between PVEC injury and COPD pathogenesis.We also explore the roles and mechanisms of various therapeutic interventions targeting PVECs,including chemical agents and traditional Chinese medicine,in the treatment of COPD.
