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， ΔΨ_m） 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 ΔΨ_m （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 ΔΨ_m 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.

This case report introduces Professor ZOU Wei 's experience of treating a patient with Wernicke encephalopathy using the "regulating spirit and promoting yang acupuncture method". The patient was diagnosed as spleen and stomach deficiency with internal liver wind. The treatment principle focused on regulating spirit and awakening the brain, strengthening the spleen, calming wind, and relaxing the tendons. Three groups of acupoints were selected: ①acupoints for awakening the brain by regulating spirit and unblocking meridians (Baihui [GV20], Qianshencong [EX-HN1] and bilateral Taiyang [EX-HN5], Fengchi [GB20]), etc.; ②acupoints for harmonizing the spleen, stomach, qi, and blood (bilateral Tianshu [ST25], Daheng [SP15], Taixi [KI3], etc.); ③acupoints for relaxing and softening the tendons (bilateral Waiguan [TE5], Hegu [LI4], Yanglingquan [GB34], Xuanzhong [GB39]).The needles were retained for 50 min per session, once daily, 7 days a week. After 16-week treatment, the patient was able to walk a few steps slowly with assistance, and other symptoms returned to normal. A two-month follow-up showed the patient's condition remained stable, walking distance further increased, and overall health significantly improved.

OBJECTIVE To optimize the forming process of Yindan huoxue tongyu granules， and evaluate the quality of the granules. METHODS Taking forming rate， angle of repose， moisture， moisture absorption rate and dissolution rate as indexes， single factor experiment combined with Plackett-Burman design was adopted to screen key process parameters； analytic hierarchy process combined with entropy weight method and Box-Behnken response surface method were used to optimize the molding process of Yindan huoxue tongyu granules， and the forming process was verified. The relative homogeneity index， bulk density， vibration density， Hausner ratio， angle of repose， moisture and hygroscopicity were used as secondary physical indexes to establish the physical fingerprints of 10 batches of Yindan huoxue tongyu granules to evaluate particle quality consistency. RESULTS The optimal molding process of Yindan huoxue tongyu granules was as follows： mannitol as the fixed excipient， the drug-assisted ratio was 1∶1（m/m） and the drying time was 1 h； 90% ethanol was used as wetting agent and the amount of it was 32%， the drying temperature was 70 ℃. The results of validation tests showed that the average comprehensive score was 97.45， which was close to the predicted value of 97.18. The similarities between the physical fingerprints of 10 batches of Yindan huoxue tongyu granules prepared by the optimal molding process and the reference physical fingerprint were all higher than 0.99. CONCLUSIONS The molding process is stable and feasible， and the quality of Yindan huoxue tongyu granules produced is stable and controllable.

Traditional Chinese medicine (TCM) exerts integrative effects on complex diseases owing to the characteristics 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.

Objective:To investigate the effects and mechanisms of angiotensin-converting enzyme 2 (ACE2) and Captopril (CAP) on mechanical ventilation-induced lung injury (VILI) in mice.Methods:Seventy-two healthy male BALB/c mice were randomly assigned (using a random number table) into six groups ( n=12 per group): normal control (NC) group, VILI group, ACE2 group, VILI+ACE2 group, CAP group, and VILI+CAP group. One hour prior to mechanical ventilation, the ACE2 and VILI+ACE2 groups were intraperitoneally injected with ACE2 at a dose of 0.1 mg/kg, while the CAP and VILI+CAP groups were intraperitoneally injected with CAP at a dose of 2.5 mg/kg. Following mechanical ventilation, serum samples were collected and enzyme-linked immunosorbent assay (ELISA) was used to detect inflammatory factors [platelet activating factor (PAF), endothelin-1 (ET-1), soluble intercellular adhesion molecule-1 (sICAM-1), prostaglandin E2 (PGE2)] and cardiovascular system related indicators [von Willebrand factor (vWF), thrombomodulin (TM), angiotensin (Ang) (1-9), Ang (1-7), prostacyclin I 2 (PGI2)]. Bronchoalveolar lavage fluid (BALF) was gathered, and total protein concentration was determined using BCA method, and sICAM-1 levels were measured by ELISA. Lung tissues were collected and subjected to hematoxylin and eosin staining (HE staining) for the assessment of pathological lung injury and lung injury scoring. Western blot and reverse transcription quantitative polymerase chain reaction (RT-qPCR) were utilized to detect the relative expression levels of ACE2 protein and mRNA, respectively. Statistical analysis was performed using IBM SPSS 20.0 software. Intergroup comparisons were conducted using one-way analysis of variance followed by the least significant difference (LSD) test. Results:No statistically significant differences were observed in the levels of PAF, ET-1, sICAM-1, vWF, TM, Ang(1-9), Ang(1-7), and PGI2 in serum and lung tissues between the ACE2/CAP groups and the NC group (all P>0.05). Compared with the VILI group, the VILI+ACE2 and VILI+CAP groups exhibited significantly decreased serum and lung tissue levels of PAF, ET-1, sICAM-1, and vWF (all P<0.05), while the levels of TM, Ang(1-9), Ang(1-7), and PGI2 were significantly increased (all P<0.05). Pathological lung injury was alleviated, and the lung wet/dry weight ratio was significantly reduced (all P<0.05) in the VILI+ACE2 and VILI+CAP groups. Furthermore, both ACE2 protein and mRNA expression levels were significantly increased in these groups (all P<0.05). Conclusion:Both ACE2 and CAP can inhibit inflammation and protect the cardiovascular system, possibly by promoting the ACE2/Ang(1-9)/Ang(1-7) axis, thereby exerting a protective effect against VILI.

Objectives:To analyze the cardiac involvement of patients with Fabry disease(FD)in Anhui region.Methods:This retrospective analysis included 48 previously and currently diagnosed FD patients(25 males)in Anhui region,overall patient and gender specific cardiac involvement was analyzed.Results:The median age of FD patients is 28.0(19.0,46.0)years.The cardiac manifestations of patients with FD were most commonly characterized by palpitations/arrhythmias(13/42 cases)and exertional dyspnea(11/42 cases),electrocardiographic changes were most commonly characterized by T-wave inversion(22/42 cases),ST-segment depression(16/42 cases),and left ventricular hypervoltage(18/42 cases),cardiac structural and functional changes were most common in papillary muscle hypertrophy(29/36 cases),bilateral sign(22/37 cases)and left ventricular hypertrophy(21/46 cases),as well as reduced left ventricular global longitudinal strain(26/39 cases).Neuropathic pain(28/43 cases)was the most common extracardiac manifestation of FD patients.FD patients of different gender differed in age at diagnosis(P=0.018),alpha galactosidase A activity(P<0.001),globotriaosylsphingosine(lyso-GL3)levels(P<0.001),enzyme replacement therapy rate(P=0.043),dyshidrosis(P<0.01),and the incidence of angiokeratoma(P=0.004).Correlation analysis showed that genotype was not correlated with enzyme activity or Lyso-GL-3 levels,whereas the Sokolow-Lyon index was positively correlated with Lyso-GL-3 levels(ρ=0.423,P=0.008),and the Sokolow-Lyon indices(septal thickness:ρ=0.562,P<0.001;left ventricle posterior wall thickness:ρ=0.569,P<0.001)and QRS duration(septal thickness:ρ=0.543,P<0.001;left ventricle posterior wall thickness:ρ=0.557,P<0.001)were positively correlated with left ventricular wall thickness.Conclusions:Cardiac involvement in patients with FD in the Anhui region is characterised by palpitations or arrhythmias,accompanied by nonspecific electrocardiographic changes.Echocardiography frequently reveals papillary muscle hypertrophy.The manifestation of cardiac involvement in patients of different genders is similar.

Objective:To summarize and analyze the clinical characteristics, drug resistance and treatment of 36 neonates with Enterobacter sepsis in the Children′s Hospital of Soochow University in the past 3 years, so as to provide reference for clinical treatment.Methods:A retrospective analysis was conducted on neonates hospitalized in the Department of Neonatology of the Children′s Hospital of Soochow University from January 2021 to March 2024 who were diagnosed with Enterobacter sepsis. The birth status, clinical manifestations, blood culture drug sensitivity, treatment status and disease outcome of the neonates were analyzed.Results:A total of 36 neonates with Enterobacter sepsis were collected. Premature infants accounted for 38.9%(14/36), and late-onset cases accounted for 66.7%(24/36). The incidence of complications was high. The main complications were central nervous system infection (15/36, 41.7%), urinary system infection (13/36, 36.1%) and neonatal necrotizing enterocolitis (7/36, 19.4%). The main pathogenic bacteria were Escherichia coli (19 cases) and Klebsiella (11 cases). Among the 19 escherichia coli strains, 7 were extended-spectrum β-lactamase (ESBL)-producing strains and 1 was carbapenem-resistant enterobacteriaceae (CRE) strain. Among the 11 Klebsiella strains, 9 were ESBL-producing strains and 6 were CRE strains. The 6 neonates with CRE sepsis were treated with sensitive antibiotics such as meropenem, amikacin and ceftazidime-avibactam, and achieved good therapeutic effects.Conclusions:Escherichia coli and Klebsiella are the main pathogens of Enterobacter sepsis in neonates, especially premature infants, with high incidence of complications and high drug resistance rate.

Objective:To compare the application effects of upper arm autogenous arteriovenous fistula (AVF) and forearm arteriovenous graft (AVG) in maintenance hemodialysis (MHD) patients, and to analyze the factors influencing the long-term patency rate of arteriovenous fistulas in MHD patients.Methods:It was a retrospective cohort study. The data of MHD patients treated in the First Affiliated Hospital of Zhejiang University School of Medicine from January 2021 to May 2023 was collected. Participants were stratified into two groups: forearm AVG and upper arm AVF. The parameters including urea clearance index (Kt/V), serum C-reactive protein (CRP), albumin levels, access-related costs, complication rates, and long-term primary patency were compared. The end event was defined as arteriovenous fistula failure, that was, the arteriovenous fistula could not be used for dialysis puncture, or the arteriovenous fistula lost function after adequate blood flow was achieved. Kaplan-Meier survival curves with log-rank tests were employed to compare access survival, while multivariable Cox regression was used to analyze the independent associated factors of patency.Results:A total of 71 MHD patients were enrolled in this study, including 35 males, with age of (64.9±11.7) years and fistula establishment time of 30.0(17.0, 58.0) months. There were 32 cases (45.1%) in the forearm AVG group and 39 cases (54.9%) in the upper arm AVF group. Compared with the forearm AVG group, the upper arm AVF group had higher serum albumin levels [38.9 (37.0, 42.1) g/L vs. 38.0 (34.6, 40.0) g/L, Z=-2.364, P=0.018], higher pain scores [3.0(2.0, 5.0) points vs. 2.0(1.0, 3.0) points, Z=-3.012, P=0.003], and higher long-term patency rates of arteriovenous fistulas (at 3, 6, 12, and 24 months, all P<0.01), while the complication rate[61.5% (24/39) vs. 93.7% (30/32), χ2=10.015, P=0.002], the cost of the access [0 (0, 9,117.0) yuan·year -1·person -1vs. 10 380.5 (7 186.0, 30 228.5) yuan·year -1·person -1, Z=-4.094, P<0.001] were lower, and the length of the available puncture vessel segment was shorter [3.5(3.0, 5.0) cm vs. 6.5(6.0, 8.0) cm, Z=-6.477, P<0.001].The Kaplan-Meier survival analysis results showed that the primary patency rate of the upper arm AVF group was significantly higher than that of the forearm AVG group (Log-rank test, χ2=23.690, P<0.001). The multivariate Cox regression analysis results indicated that the type of fistula being forearm AVG (with upper arm AVF as reference, HR=4.907, 95% CI 1.740-13.840) and increased complications number ( HR=1.234, 95% CI 1.040-1.464) were the independent factors promoting the arteriovenous fistula failure in MHD patients. Conclusions:The type of internal fistula and the complications are the factors affecting the long-term patency rate of internal fistula in MHD patients.Upper arm AVF offers cost-effectiveness and sustained patency advantages over forearm AVG but requires careful consideration of puncture challenges and patient discomfort. Individualized access selection should balance anatomical constraints with clinical priorities.
