The chronicity of infectious diseases is an important field in the collaborative research of traditional Chinese and Western medicine. The warm disease theory of pathogen invading nutrient and blood aspects in traditional Chinese medicine （TCM） takes the struggle between healthy Qi and pathogenic Qi and cementation of Yin as the core pathogenesis， providing a unique theoretical framework for explaining the common pathology of infectious chronic diseases. This theory originated from Yin-Yang interaction in the Internal Classic and was enriched with WU Youke's theory of intruding pathogen interacting and lingering in blood vessels and YE Tianshi's theory of long-term illness entering collaterals. Combining the theory with modern medical knowledge， our team has condensed the dynamic pathogenesis model of deficiency （nutrient and blood aspects） and excess （pathogen） interacting in the blood collaterals of Yin aspect， the core feature of which is the four-dimensional interactions of cause （pathogen characteristics）， location （three Yin locations of diseases）， nature （deficiency and excess）， and potential （transmission trend）. The common pathology of infectious chronic diseases is reflected in interactions. That is， the interactions between nutrient and blood deficiency （immune exhaustion and metabolic disorder） and pathogen excess （pathogen persistence and fibrous hyperplasia） in the liver collaterals （Jueyin）， kidney collaterals （Shaoyin）， lung collaterals （Taiyin） and other blood collaterals of Yin aspect form the pathological damage characterized by immune inflammatory response-continuous tissue damage with excessive repair. Taking the inheritance and innovative development of classics as the main line， this paper systematically discusses the scientific connotation of the theory of pathogen invading nutrient and blood aspects and the paths of inheritance and innovation and clarifies the original significance of this theory in the chronic development of infectious diseases. Furthermore， taking clinical diseases as an example， this paper reflects the guiding value of this classical theory in the modern diagnosis and treatment of infectious diseases with integrated traditional Chinese and Western medicine and the application potential of this theory in solving complex medical problems through the construction of the innovative paradigm of precise diagnosis and treatment with integrated traditional Chinese and Western medicine.

Hepatocellular carcinoma （HCC）， a malignancy with high mortality， exhibits poor survival rates and prognosis. The profound suppression of the tumor immune microenvironment （TIME） and the abnormal hyperactivity of metabolic reprogramming （MR） are the two primary factors driving HCC progression. Traditional Chinese medicine has demonstrated significant efficacy in HCC treatment. The team proposed that "deficiency of healthy Qi and stasis toxins" was the core pathogenesis of HCC， closely associated with TIME suppression and MR hyperactivity. This paper proposed that a suppressed state of the TIME was the biological manifestation of "deficiency of healthy Qi"， where the functional exhaustion of effector T lymphocytes and natural killer cells reflected the decline of "healthy Qi" in eliminating pathogens. Conversely， the expansion and activation of immunosuppressive cells， such as regulatory T cells （Tregs）， M2-like tumor-associated macrophages （TAM-M2）， and myeloid-derived suppressor cells （MDSCs） ， represent the dysfunction of "healthy Qi" in maintaining homeostasis. MR serves as the material basis of "stasis toxins". Stasis toxins exhibit heat stagnation， manifested by abnormal hyperactivity of glycolysis and lipid synthesis. They demonstrate migratory propensity， as toxic metabolites like lactic acid and prostaglandin E2 promote tumor invasion and metastasis. They display a consumptive nature， reflected in the functional suppression of immune cells. The vicious cycle between TIME and MR is the biopathological reflection of "deficiency of healthy Qi intertwined with stasis toxins". Immunosuppression exacerbates MR， while toxic metabolites further impair immune function， establishing a pathogenic chain of "deficiency leading to stasis， and stasis toxins damaging healthy Qi". The primary therapeutic approach is reinforcing healthy Qi， resolving stasis， and removing toxins， which can reinforce and tonify healthy Qi to regulate pathways， such as phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， C-X-C chemokine receptor type 4/ C-X-C chemokine ligand 12 （CXCR4/CXCL12）， and toll-like receptor 4/ nuclear factor-kappa B/ signal transducer and activator of transcription 3 （TLR4/NF-κB/STAT3）， adjust T lymphocyte ratios， inhibit Tregs/TAM-M2 function， and downregulate immune checkpoints， including programmed death ligand 1/programmed death 1（PD-L1/PD-1）， and reshape TIME. It is also involved in resolving stasis and removing toxins to modulate phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR） and hypoxia-inducible factor-1α （HIF-1α） signaling pathways， suppress key enzymes in glycolysis and lipid synthesis， and block toxic metabolite production. Thus， this therapy synergistically regulates the immune and metabolic network， breaks the vicious cycle of "deficiency in healthy Qi and stasis toxins"， and offers a novel strategy for integrating traditional Chinese medicine and Western medicine in HCC treatment.

The best evidence included a total of 34 pieces in seven aspects of comprehensive screening, nursing plan construction, preoperative prehabilitation, nutritional interventions, Chinese medicine interventions, exercise interventions, and psychological interventions for frailty.Conclusions:The summary of the best evidence for frailty management in patients undergoing postoperative chemotherapy for gastric cancer may provide an evidence-based basis for frailty interventions by clinical medical and staff.

Objective:To investigate the effect of tumor necrosis factor α (TNF-α) on the permeability of blood labyrinth barrier in C57BL/6J male mice and its possible mechanism.Methods:As for the design of animal experiment, twenty male C57BL/6J mice aged 6-8 weeks were randomly divided into control group and cisplatin group with 10 mice in each group by software method. The control group was intraperitoneally injected with normal saline every day, and the cisplatin group was intraperitoneally injected with 4 mg/kg cisplatin for 4 consecutive days. After administration, auditory brainstem response (ABR) was used to detect hearing changes in mice. HE staining was used to observe the morphological changes of mouse cochlea vasculature. The expression of TNF-α was detected by immunohistochemistry and ELISA. The permeability of the blood labyrinth barrier was observed by Evans blue staining. With respect to the design of cell experiment, primarily cultured cochlea pericytes (PC) and endothelial cells (EC) were divided into EC group, EC+TNF-α group, EC+PC group, EC+PC+TNF-α group, EC+PC+TNF-α+SB-3CT (MMP-9/MMP-2 secretion inhibitor) group, PC group, PC+TNF-α group, PC+TNF-α+LY294002 (PI3K/AKT pathway inhibitor) group, PC+LY294002 group. The protein expressions of ZO-1, VE-cadherin, MMP-9, MMP-2, PI3K, p-PI3K, AKT, and p-AKT were detected by Western blot. TEER and FITC-dextran penetration experiment were used to detect EC resistance and monolayer EC permeability, respectively. The data were statistically analyzed using GraphPad Prism 8 software.Results:In animal experiment, compared with control group, the ABR response threshold of mice in cisplatin group was increased ( P<0.01). The vaccine ular structure of the cochlea was disordered red, wrinkled and vacuole increased. The extravasation of vascular red fluorescent dye increased ( P<0.05), and also, levels of serum TNF-α and cochlear veins increased ( P<0.01). In cell experiment, by treatment of EC with different concentrations of cisplatin, 20 μmol cisplatin led to the highest expression of TNF-α ( P<0.01). The expression of TNF-α was the highest after 3 h intervention in EC ( P<0.05). Compared with those in EC+PC group, the resistance value of EC was decreased, the permeability of monolayers EC was increased, the expression of ZO 1 and VE cadherin proteins was decreased, and however, the resistance value was increased and the permeability of EC was decreased after the intervention of SB-3CT in EC+PC+TNF-α group. The expressions of ZO-1 and VE-cadherin proteins were increased ( P<0.05). The expression of MMP-9 increased after TNF-α intervention ( P<0.05), the expression of MMP-2 had no significant change, and the expression of p-PI3K/PI3K and p-AKT/AKT were increased ( P<0.05). The expression of MMP-9 decreased in PC+TNF-α+LY294002 group ( P<0.05). Conclusion:The hearing loss of C57BL/6J male mice induced by cisplatin may be related to the increased release of TNF-α from the blood labyrinth barrier EC in the cochlear stria vascularis, and the activation of PI3K/AKT signaling pathway by TNF-α in PC, which increases the secretion of MMP-9 from PC, ultimately leads to the increased permeability of the blood labyrinth barrier.

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.
