This study establishes an integrated research paradigm based on traditional Chinese medicine (TCM) theory, guided by pathological characteristics, centered on formula compatibility principles, and supported by multidisciplinary technologies, to systematically analyze the mechanisms of hepatotoxicity induced by toxic Chinese herbal medicinals and strategies for reducing toxicity through compatibility. The findings revealed that the pathomechanism aligns closely with the "liver aversion to acute irritation" theory from Inner Canon of Yellow Emperor (《黄帝内经》). The core pathology involves an imbalance between liver's form and function, which is characterized by malnourishment of liver form due to yin-blood depletion and dysfunction in ascending-dispersing and free-flowing activities, and closely linked to modern pathological mechanisms such as microcirculatory disturbances, oxidative stress, inflammatory response, metabolic disorder and gut-liver axis dysregulation. Based on this, a multi-layered compatibility strategy for toxicity reduction is put forward, which involves using sweet medicinals to alleviate urgency, balancing the liver form and its function, and pre-regulating other organs. This provides a theoretical basis for the safe application of toxic Chinese herbal medicinals.

ObjectiveTo investigate the mechanism of Guizhi Fulingwan (GFW) against hepatic fibrosis, focusing on elucidating the regulatory effect of GFW on the mitochondrial DNA (mtDNA)/NOD-like receptor protein 3 (NLRP3)/cysteinyl aspartate-specific proteinase-1 (Caspase-1)/gasdermin D (GSDMD) signaling pathway. MethodsForty-two male Sprague-Dawley (SD) rats were randomly allocated into six groups (n=7): control, model, low/medium/high-dose (0.14, 0.28, 0.56 g·kg-1·d-1) GFW (GFW-L, GFW-M, GFW-H), and Dahuang Zhechong pills (DZW, 1.8 g·kg-1·d-1). The rat model of hepatic fibrosis was induced by intraperitoneal injection of carbon tetrachloride. General conditions of the rats were observed. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured. Liver histopathology and collagen deposition were observed through hematoxylin and eosin (HE) staining and Masson's trichrome staining. Transmission electron microscopy (TEM) was employed to observe structural alterations and damage of cellular ultrastructures including mitochondria. Mitochondrial membrane potential (MMP, ΔΨm) was detected by flow cytometry. Serum levels of interleukin-1β (IL-1β) and interleukin-18 (IL-18) were measured by enzyme-linked immunosorbent assay (ELISA). The mRNA levels of mtDNA and NLRP3 in the liver tissue were quantified by Real-time polymerase chain reaction (Real-time PCR). The protein levels of key molecules in the NLRP3/Caspase-1/GSDMD signaling pathway in the liver tissue were determined by Western blot. ResultsCompared with the control group, the model group exhibited a decrease in body weight (P<0.01), an increase in liver index (P<0.01), elevations in serum ALT and AST levels (P<0.01), and typical fibrotic features such as disorganized hepatocytes, inflammatory infiltration, and increased collagen deposition in the liver tissue. TEM revealed significant karyotheca degeneration, mitochondrial swelling, endoplasmic reticulum expansion, and organelle efflux in the model group. In addition, the model group showed decreased ΔΨm (P<0.01), up-regulated mRNA levels of mtDNA and NLRP3 (P<0.01) and protein levels of NLRP3, Caspase-1, and GSDMD (P<0.01) in the liver tissue, and increased serum levels of IL-1β and IL-18 (P<0.01). Compared with that in the model group, the body weight increased in GFW-L, GFW-M, and DZW groups (P<0.05) and markedly increased in the GFW-H group (P<0.01). The liver index decreased in the GFW groups and DZW group (P<0.01). The serum ALT level declined in the GFW-L group (P<0.05), and the serum ALT and AST levels decreased in the GFW-M, GFW-H, and DZW groups (P<0.01). Histopathological damage and fibrosis were alleviated to varying degrees, and TEM revealed mitigated ultrastructural injuries including mitophagy, mitochondrial swelling, and endoplasmic reticulum expansion in the drug intervention groups. The ΔΨm increased in GFW groups without statistical significance. The mRNA level of mtDNA in the liver tissue was down-regulated in the GFW-M (P<0.05), GFW-H (P<0.01), and DZW (P<0.01) groups. The mRNA level of NLRP3 was down-regulated in GFW-M, GFW-H, and DZW groups (P<0.01). Western blot analysis showed significantly down-regulated protein level of NLRP3 in all the GFW groups and the DZW group (P<0.01). The protein level of GSDMD-N was down-regulated in GFW-H and DZW groups (P<0.01). The protein level of cleaved Caspase-1 was down-regulated in GFW-M (P<0.05), GFW-H (P<0.01), and DZW (P<0.01) groups. In addition, the serum levels of IL-1β and IL-18 declined in GFW-H and DZW groups (P<0.01). ConclusionGFW can suppress pyroptosis to ameliorate CCl4-induced hepatic fibrosis, potentially through mitigating mitochondrial damage, inhibiting inflammasome assembly and activation, and blocking pro-inflammatory cytokine release.

OBJECTIVE To investigate the molecular mechanism of Tiaozhong huashi decoction in improving gastroesophageal reflux disease (GERD) by regulating endoplasmic reticulum autophagy in rat esophageal interstitial cells of Cajal (ICC) through p62 signaling pathway.METHODS After establishing a rat GERD model via the weak acid intragastric administration and irregular diet, the rats were randomly divided into model group, western medicine group [1.56 mg/(kg·d) of mosapride, 3.125 mg/(kg·d) of lansoprazole] and low-, medium- and high-dose Tiaozhong huashi decoction [4.713, 9.425, 18.85 g/(kg·d)] groups. A blank group was also set up, with 8 rats in each group. The rats in each group were intragastrically administered with corresponding liquid or normal saline twice a day for 14 days. During the intervention period, the general conditions of rats’ hair, spirit, diet and defecation were observed. After the last gavage, the pathological changes of esophageal tissue and the ultrastructure of ICC were observed. The relative expression and positive expression levels of p62, autophagy-related protein 8 (ATG8), 200 kDa FAK family kinase-interacting protein (FIP200) and Unc-51 like autophagy activating kinase 1 (ULK1) in esophageal tissue were detected.RESULTS Compared with the blank group, rats in the model group exhibited listlessness; thickening of the esophageal basal layer, elongation of lamina propria papillae with inflammatory cell infiltration; markedly dilated endoplasmic reticulum appearing as round vacuolar cisternae with ribosome detachment; and a small number of accumulated autophagosomes. The relative expression and positive expression levels of p62, ATG8, FIP200, and ULK1 were significantly decreased ( P <0.05). Compared with the model group, the above pathological injuries in the medium- and high-dose Tiaozhong huashi decoction groups had all improved to varying degrees; the damaged endoplasmic reticulum structure was repaired, and no autophagosome accumulation was observed. In particular, the relative expression levels and positive expression levels of p62, ATG8, FIP200, and ULK1 in esophageal tissue of rats in the medium-dose Tiaozhong huashi decoction group were significantly increased ( P <0.05).CONCLUSIONS Tiaozhong huashi decoction ameliorated esophageal mucosal injury in GERD rats, and its mechanism was possibly associated with activation of the p62 signaling pathway and restoration of the endoplasmic reticulum structure, morphology, and autophagic capacity of ICC.

Objective:To investigate the function changes in neurovascular coupling (NVC) in patients with white matter hyperintensities (WMHs) and its correlation with cognitive impairment.Methods:Thirty patients with moderate to severe WMHs admitted to the First People's Hospital of Changzhou from April 2023 to June 2024 (as case group), and 30 subjects with no or mild WMH matched by age, gender and educational level (as the control group) were included prospectively. The general clinical information was collected and cognitive assessment was conducted. Three-dimensional pseudo-continuous arterial spin labeling (3D-pCASL) and resting state functional magnetic resonance imaging (rs-fMRI) data were collected to quantify cerebral blood flow (CBF) and functional connectivity strength (FCS). NVC function was evaluated through voxel-wise CBF-FCS correlation analysis. The CBF-FCS coefficients between groups were compared, the correlation between NVC and cognitive function was explored using partial correlation analysis, controlling for the false discovery rate (FDR).Results:The prevalence of hypertension and diabetes in moderate to severe WMHs group was significantly higher than that in the no or mild WMH group (all P<0.05), while the overall cognitive function, executive function and episodic memory function were significantly lower than those in the no or mild WMH group (all P<0.05). There was no significant difference in the CBF-FCS coefficients of the whole brain gray matter between the moderate to severe WMHs group and the no or mild WMHs group. The CBF-FCS coefficients of the bilateral orbital frontal gyrus, right anterior cingulate gyrus, and bilateral hippocampus in the moderate to severe WMHs group were significantly lower than those in the no or mild WMHs group, while the CBF-FCS coefficients of the bilateral parietal gyrus and caudate nucleus were significantly higher than those in the no or mild WMHs group (all q<0.05 after FDR adjustment). Partial correlation analysis showed that after adjusting for age, gender, and education level, the CBF-FCS coefficients of the right anterior and lateral cingulate gyrus were negatively correlated with the executive function completion time in the moderate to severe WMHs group ( r=-0.55, q=0.04 after FDR adjustment), and the CBF-FCS coefficients of the right hippocampus were significantly positively correlated with the episodic memory scores ( r=0.59, q=0.03 after FDR adjustment). These correlations were not statistically significant in the no or mild WMHs group. Conclusion:Patients with moderate to severe WMHs exhibit NVC abnormalities in specific brain regions, which are closely associated with executive function and episodic memory impairment, suggesting that NVC dysfunction may be an important mechanism for WMHs-related cognitive impairment.

Objective :
To investigate the impact of fecal microbiota transplantation (FMT) on the composition of 15 intestinal-derived estrogens and their metabolites (EMs) and its correlation with non-alcoholic fatty liver disease (NAFLD) .
Methods:
Thirty male C57BL/6J mice were divided into a normal control group (Control) , a high- sugar high-fat diet combined with low-dose CCl4 -induced NAFLD model group ( Model) , and a group of model mice treated with fecal microbiota from normal female mice (FMT) . After 17 weeks of modeling , liver pathology in each group was observed using HE staining , biochemical methods were used to measure serum alanine aminotrans- ferase (ALT) and aspartate aminotransferase (AST) levels , as well as hepatic triglyceride (TG) and total choles- terol (TC) levels. and the content of 15 EMs in portal vein serum was detected using ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS) . The correlation between disease phenotype and intesti- nal EMs was analyzed using Pearson ′s method.
Results:
The NAFLD model was successfully established , and the FMT group showed improved liver structure and morphology , with significant decreases in liver function and hepatic lipids compared to the Model group. In NAFLD mice , the contents of E1 , E2 , and their 2- and 4-position metabo- lites in portal vein blood serum was reduced compared to normal mice , while the content of most 16- and 17-posi- tion metabolites ( except 16α-OHE1) increased compared to normal mice. Correlation analysis showed that ALT was strongly positively correlated with E3 and 17-epiE3 , and strongly negatively correlated with E1 , E2 , 4- MeOE1 , and 16α-OHE1 . The TC was strongly positively correlated with 17-epiE3 and strongly negatively correla- ted with E1 , 4-MeOE1 , and 16α-OHE1 .
Conclusion
FMT restores the disrupted composition of intestinal EMs and improves NAFLD.

Traditional Chinese medicine(TCM)exerts integrative effects on complex diseases owing to the char-acteristics of multiple components with multiple targets.However,the syndrome-based system of diagnosis and treatment in TCM can easily lead to bias because of varying medication preferences among physicians,which has been a major challenge in the global acceptance and application of TCM.Therefore,a standardized TCM prescription system needs to be explored to promote its clinical application.In this study,we first developed a gradient weighted disease-target-herbal ingredient-herb network to aid TCM formulation.We tested its efficacy against intracerebral hemorrhage(ICH).First,the top 100 ICH targets in the GeneCards database were screened according to their relevance scores.Then,SymMap and Traditional Chinese Medicine Systems Pharmacology(TCMSP)databases were applied to find out the target-related ingredients and ingredient-containing herbs,respectively.The relevance of the resulting ingredients and herbs to ICH was determined by adding the relevance scores of the corresponding targets.The top five ICH therapeutic herbs were combined to form a tailored TCM prescriptions.The absorbed components in the serum were detected.In a mouse model of ICH,the new prescription exerted multifaceted effects,including improved neurological function,as well as attenuated neuronal damage,cell apoptosis,vascular leakage,and neuroinflammation.These effects matched well with the core pathological changes in ICH.The multi-targets-directed gradient-weighting strategy presents a promising avenue for tailoring precise,multipronged,unbiased,and standardized TCM prescriptions for complex diseases.This study provides a paradigm for advanced achievements-driven modern innovation in TCM concepts.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective:To evaluate the predictive value of simplified geriatric assessment (sGA) in elderly Chinese patients diagnosed with diffuse large B-cell lymphoma (DLBCL) .Methods:It retrospectively analyzed the relationships of sGA with the clinical characteristics, outcome, and prognosis of 219 patients aged ≥60 years who were newly diagnosed with DLBCL at six hospitals in Jiangsu province between January 2018 and December 2022.Results:The median age of 219 patients was 68 years (60-87 years). According to the sGA system criteria, 101 (46.1%), 103 (47.0%), and 15 (6.8%) elderly patients with DLBCL were categorized as fit, unfit, and frail, respectively. The most common adverse reactions after chemotherapy were hematologic, and the incidence of grade >2 hematologic adverse reactions was similar among the three groups (47.5% vs 41.7% vs 46.7%, respectively; χ2=0.712, P=0.700). Compared with the fit and unfit groups, the frail group showed tendencies toward for higher proportions of grade >2 gastrointestinal, pulmonary, and infectious adverse reactions ( P>0.05 for all). The fit, unfit, and frail groups had respective remission rates of 74.3%, 46.6%, and 20.0% ( χ2=25.249, P<0.001) ; disease progression rates of 5.9%, 11.7%, and 26.7% ( χ2=6.763, P<0.05) ; 2-year overall survival rates of 92.1% (95% CI 86.6% to 97.9%), 77.6% (95% CI 69.5% to 86.6%), and 70.1% (95% CI 49.4% to 99.6%) ( P<0.05) ; and 2-year progression-free survival rates of 76.8% (95% CI 67.0% to 84.8%), 69.7% (95% CI 61.8% to 82.0%), and 65.7% (95% CI 53.3% to 100%) ( P=0.399) . Conclusion:sGA can effectively predict treatment adverse effects and efficacy, disease progression, and long-term survival in elderly DLBCL.
