Hepatic fibrosis （HF） is an abnormal repair process that occurs after chronic liver injury. It is characterized by excessive accumulation of extracellular matrix in the liver， resulting in fibrous tissue hyperplasia， which may further develop into cirrhosis and even liver cancer. Currently， there is a lack of specific anti-HF drugs in clinical practice. Traditional Chinese medicine （TCM） has advantages in the treatment of HF， including multi-component and multi-target interventions with high safety， and can significantly delay the progression of HF. It has therefore become a current research hotspot. Nuclear factor erythroid 2-related factor 2 （Nrf2）， as a key transcription factor involved in antioxidant stress， can effectively intervene in the progression of HF by activating the expression of downstream antioxidant enzymes and detoxification genes. This article systematically reviews the mechanisms by which active components of Chinese medicine （such as flavonoids， polysaccharides， and saponins） and TCM compound prescriptions （such as Haobie Yangyin Ruanjian prescription and Biejia Xiaozheng pills） exert anti-fibrotic effects through activation of the Nrf2 signaling pathway， including enhancing antioxidant capacity， inhibiting inflammatory responses， reducing hepatocyte apoptosis， improving mitochondrial function， and inhibiting the ferroptosis pathway. In addition， this article points out the current shortcomings in research based on the Nrf2 signaling pathway and proposes corresponding suggestions to promote related studies. It also provides an important theoretical basis for the development of novel anti-HF Chinese medicine targeting Nrf2.

ObjectiveTo explore the mechanism by which Yinchenhao Tang intervenes in α-naphthylisothiocyanate （ANIT）-induced cholestatic liver injury by regulating the Takeda G-protein-coupled receptor 5（TGR5）/NOD-like receptor protein 3（NLRP3）/cysteine aspartate-specific protease-1 （Caspase-1） pyroptosis signaling pathway. MethodsForty male Wistar rats were randomly assigned into blank， model， ursodeoxycholic acid， and Yinchenhao Tang groups. Except the blank group， other groups were treated with ANIT dissolved in olive oil for the modeling of cholestatic liver injury. Ursodeoxycholic acid （0.1 g·kg^-1） and Yinchenhao Tang （9.23 g·kg^-1） were administered by gavage. The blank group and the model group were administrated with the same amount of pure water， once a day for 3 days. The blood and liver tissue samples were collected， and the serum levels of liver function indicators were measured by an automatic biochemical analyzer. Hematoxylin-eosin staining was employed to observe the pathological changes of the liver. The levels of interleukin （IL）-1β and IL-18 in the liver tissue were determined by ELISA. The mRNA levels of IL-1β， IL-18， TGR5， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， Caspase-1， and GSDMD in the liver tissue were assessed by Real-time PCR. The protein levels of TGR5， NLRP3， ASC， Caspase-1， and GSDMD in the liver tissue were determined by Western blot. ResultsCompared with the blank group， the model group showed elevated levels of alanine amino-transferase （ALT）， aspartate transferase （AST）， alkaline phosphatase （ALP）， total bile acid （TBA）， and total bilirubin （TBil） in the serum （P<0.01）， inflammatory cell infiltration， hepatocyte swelling， and bile duct epithelial cell proliferation in the liver， raised levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA and protein levels of TGR5 （P<0.01）， up-regulated mRNA levels of IL-18 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， IL-1β （P<0.05）， and NLRP3 （P<0.05）， and up-regulated protein levels of NLRP3 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， and GSDMD （P<0.05）. Compared with the model group， the ursodeoxycholic acid group showed declined levels of AST （P<0.01）， TBA （P<0.01）， TBil （P<0.01）， and ALT （P<0.05） in the serum， lowered levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA levels of NLRP3 （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， IL-1β （P<0.05）， IL-18 （P<0.05）， and ASC （P<0.05）， up-regulated mRNA and protein levels of TGR5 （P<0.05）， and down-regulated protein levels of NLRP3， ASC， Caspase-1， and GSDMD （P<0.05）. Compared with the model group， the Yinchenhao Tang group showed lowered levels of ALT， AST， ALP， TBA， and TBil in the serum （P<0.01）， declined levels of IL-1β and IL-18 in the liver tissue （P<0.01）， down-regulated mRNA levels of IL-1β （P<0.01）， NLRP3 （P<0.01）， ASC （P<0.01）， Caspase-1 （P<0.01）， GSDMD （P<0.01）， and IL-18 （P<0.05）， up-regulated mRNA and protein levels of TGR5 （P<0.01）， and down-regulated protein levels of Caspase-1 and GSDMD （P<0.05）. The liver tissue of the administration groups showed reduced infiltration of inflammatory cells， reduced swelling of hepatocytes， and alleviated proliferation of bile duct epithelial cells. ConclusionYinchenhao Tang can ameliorate ANIT-induced cholestatic liver injury by regulating the hepatocyte pyroptosis mediated by the TGR5/NLRP3/Caspase-1 signaling pathway.

ObjectiveThis study aims to investigate the mechanism of Yinchenhao Tang （YCHT） in regulating macrophage polarization to alleviate cholestatic liver injury，focusing on the TLR4/NF-κB signaling pathway as the entry point. MethodsCholestasis was induced in Wistar rats through a single gavage of 100 mg·kg^-1 α-naphthyl isothiocyanate （ANIT） dissolved in olive oil. The animals were randomly divided into four groups：Model group，YCHT group，ursodeoxycholic acid （UDCA） group （n=10），and a blank group （n=10） that received only 5 mL·kg^-1 olive oil. The YCHT group received 9.23 g·kg^-1·day^-1 of YCHT by gavage，and the UDCA group was treated with 0.1 g·kg^-1·day^-1 of UDCA suspension. Both the normal and model groups were given an equal volume of normal saline，all for three consecutive days. Serum liver function was assessed using an automatic biochemical analyzer. Hematoxylin-eosin （HE） staining was used to observe liver tissue morphology. Levels of tumor necrosis factor-α （TNF-α），interleukin-1β （IL-1β），transforming growth factor-β （TGF-β），and interleukin-10 （IL-10） were quantified in liver homogenate supernatants via enzyme-linked immunosorbent assay （ELISA）. Western blot analysis measured the relative protein expression of Toll-like receptor 4 （TLR4），nuclear factor-κB （NF-κB），CD206，inducible nitric oxide synthase （iNOS）， CD86，and arginase-1 （Arg-1）. The relative mRNA expression of TLR4/NF-κB，CD206，iNOS，CD86，and Arg-1 in liver tissue was evaluated using real-time quantitative PCR. ResultsCompared with the normal group，the model group exhibited significantly elevated levels of alkaline phosphatase （ALP），total bile acid （TBA），total bilirubin （TBil），aspartate aminotransferase （AST），and alanine aminotransferase （ALT） （P<0.01）. There was a portal area expansion and pronounced inflammatory cell infiltration. The expression of pro-inflammatory markers TNF-α and IL-1β was significantly upregulated （P<0.01），and macrophage markers CD86 and CD206 showed positive expression. Protein and mRNA expressions of iNOS and CD86 were significantly elevated （P<0.01）. The mRNA and protein expressions of the related pathway molecules TLR4 and NF-κB were significantly increased （P<0.01）. Compared with those in the model group， the liver function indicators in the YCHT group showed significant decreases （P<0.05， P<0.01）. The bile duct hyperplasia was significantly alleviated， and the tissue structure became more orderly. The levels of IL-1β and TNF-α were significantly reduced （P<0.01）， while the expression levels of IL-10 and TGF-β significantly increased （P<0.05， P<0.01）. The expression of CD86 significantly decreased （P<0.01）， and the expression of CD206 significantly increased （P<0.01）. The protein and mRNA expressions of iNOS and CD86 significantly decreased （P<0.01）， and those of Arg-1 significantly increased （P<0.01）. The protein and mRNA expressions of CD206 significantly increased （P<0.05， P<0.01）， and the mRNA and protein expressions of related pathway molecules TLR4 and NF-κB significantly decreased （P<0.01）. ConclusionYCHT ameliorates cholestatic liver injury in rats by improving bile metabolism，reducing bile duct dilatation，and mitigating inflammation. These effects are achieved through the inhibition of M1 macrophage activation and the promotion of M2 macrophage polarization，likely via modulation of the TLR4/NF-κB signaling pathway.

Cholestatic liver injury refers to the bile production， secretion， and excretion disorder caused by various reasons. It induces liver injury， metabolic disorders， and dysfunction of the hepatobiliary system， which can further develop into liver fibrosis， cirrhosis， liver failure， and even death. At present， the preferred drug for clinical treatment is ursodeoxycholic acid， which， however， induces adverse reactions and is intolerant in some patients. Yinchenhao Tang is a representative prescription of traditional Chinese medicine for the treatment of jaundice due to Yang jaundice. It has the effects of clearing heat， eliminating dampness， and removing jaundice and has shown good therapeutic effect in long-term clinical application. Modern pharmacological studies have found that this prescription has anti-inflammatory， anti-oxidation， bile acid balance-regulating， hepatocyte apoptosis-inhibiting and other liver-protecting effects. This paper reviews the relevant clinical and animal experimental studies on Yinchenhao Tang in the treatment of cholestatic liver injury in recent years. Yinchenhao Tang can intervene in the progression of cholestatic liver injury by regulating bile acid metabolism and excretion， reducing inflammatory response， inhibiting oxidative stress， alleviating endoplasmic reticulum stress， inhibiting hepatocyte apoptosis， and protecting intestinal mucosal barrier. This paper systematically expounds the molecular mechanisms by which Yinchenhao Tang regulates cholestatic liver injury that are confirmed by current research， aiming to provide reference for the clinical application and in-depth study of Yinchenhao Tang.

Objective To investigate the incidence and epidemiological characteristics of herpes zoster in Jinshan District, Shanghai, in 2024, and to provide a scientific basis for the development of prevention and control measures. Methods The visit information of herpes zoster cases in 2024 was collected through the outpatient diagnosis and treatment system of medical institutions in Jinshan District. Descriptive epidemiological methods were used for statistical analysis. Results In 2024, there were a total of 7 270 cases of herpes zoster in Jinshan District, including 3 398 male cases and 3 872 female cases. The incidence rate among females was higher than that among males (χ² =125.25, P< 0.001). Cases occurred in all age groups, with an average age of 59.58 ± 15.28 years. The highest proportion of cases was in the 50-year-old group (21.99%) and the 60-year-old group (25.45%). The incidence rate increased with age (χ² = 4 505.99, P< 0.001). The main departments for consultation were dermatology, pain clinics, and neurology. The main clinical diagnoses were herpes zoster without complications, postherpetic neuralgia, and incomplete herpes zoster. Among the cases, 3,102 patients had follow-up visits, and the number of follow-up visits increased with age. From 2020 to 2024, a total of 2,032 doses of herpes zoster vaccine were administered in the district, with the highest vaccination rate in the 50-year-old group (54.48%). Conclusion The majority of herpes zoster cases in Jinshan District are concentrated in the 50- and 60-year-old groups. The main complication is postherpetic neuralgia. The incidence rate and number of follow-up visits increase with age. The vaccination rate of herpes zoster vaccine in the entire district is relatively low. It is recommended to enhance monitoring and analysis, carry out health education for key populations (aged 50 years old and above), and promote vaccination and other preventive and control measures.

BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

OBJECTIVES: To study the therapeutic mechanism of Tuihuang Mixture against cholestasis. METHODS: Forty-eight Wistar rats were randomized equally into blank group, model group, ursodeoxycholic acid group and Tuihuang Mixture group. Except for those in the blank group, all the rats were given α‑naphthylisothiocyanate (ANIT) to establish rat models of cholestasis, followed by treatments with indicated drugs or distilled water. Serum levels of ALT, AST, ALP, γ-GT, TBA and TBIL of the rats were determined, and hepatic expressions IL-1β, IL-18, FXR, NLRP3, ASC, Caspase-1 and GSDMD were detected using q-PCR, ELISA or Western blotting. Histopathological changes of the liver tissues were observed using HE staining. RESULTS: The rat models of cholestasis had significantly increased serum levels of ALT, AST, ALP, γ-GT, TBA and TBIL with increased mRNA and protein expressions of IL-1β and IL-18, decreased protein and mRNA expressions of FXR, and increased protein expressions of NLRP3 and Caspase-1 and mRNA expressions of NLRP3, ASC, Caspase-1 and GSDMD in the liver tissue, showing also irregular arrangement of liver cells, proliferation of bile duct epithelial cells and inflammatory cells infiltration. Treatment of the rat models with Tuihuang Mixture significantly decreased serum levels of ALT, AST, ALP, γ-GT, TBA and TBIL, lowered IL-1β and IL-18 and increased FXR protein and mRNA expressions, and reduced NLRP3, ASC, Caspase-1 and GSDMD proteins and NLRP3, ASC and Caspase-1 mRNA expressions in the liver tissue. Tuihuang Mixture also significantly alleviated hepatocyte injury, bile duct epithelial cell proliferation and inflammatory cell infiltration in the liver of the rat models. CONCLUSIONS Tuihuang Mixture can effectively improve cholestasis in rats possibly by inhibiting NLRP3 inflammatosome-mediated pyroptosis via regulating FXR.

Salvia miltiorrhiza (Danshen) is a traditional Chinese herb that is commonly known for its cardiovascular and hepatoprotective benefits. Recent studies have confirmed that Danshen and its bioactive components can influence gut microbial homeostasis, thereby affecting Helicobacter pylori (HP) colonization in the human stomach. HP is a bacterial pathogen associated with various gastrointestinal diseases. Current HP treatments mainly involve antibiotics and proton pump inhibitors. However, their efficacy is strongly compromised by the rapid emergence of antibiotic resistance in HP and genetic heterogeneity among patients. The interaction between Danshen and gut microbial status provides a novel perspective for HP treatment. Understanding the medical properties of Danshen in altering gut microbiota and eliminating HP, as well as the underlying mechanisms, is important for improving human gastrointestinal healthcare. This review investigates the interaction between Danshen and gut microbiota and its impact on HP infection using databases including Web of Science, PubMed, and Google Scholar. We explored the unconventional intersection between Danshen, gut microbiota, and HP infection, shedding light on their intricate interplay and potential therapeutic implications. A comprehensive understanding of this interaction provides valuable insights into developing novel therapeutic strategies that target the gut microbiota to mitigate HP-associated gastrointestinal disorders.
