ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory, Qijia Rougan prescription, combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted, and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis (CHB-HF) who met the diagnosis and inclusion criteria were randomly assigned to an observation group (Qijia Rougan prescription + entecavir) and a control group (entecavir). The treatment duration was 24 weeks. Liver stiffness measurement (LSM), fibrosis-4 index (FIB-4), portal vein diameter, hepatitis B serology, biochemical indicators, hepatic fibrosis markers in serum [hyaluronic acid (HA), laminin (LN), procollagen Ⅲ peptide (PⅢP), and type Ⅳ collagen (Ⅳ-C)], and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis, with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment, the observation group showed a significant reduction in LSM and FIB-4 (P<0.01), as well as notable improvements in LN, Ⅳ-C, and various TCM syndrome scores (P<0.05, P<0.01). When compared to the control group after treatment, the observation group demonstrated significant improvements in LSM, FIB-4, and various TCM syndrome score indicators (P<0.05, P<0.01), indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment, the observation group had better improvement in regression of stages F2 and F3 (P<0.05). When compared to the control group after treatment, the observation group exhibited superior improvement in regression of stage F3 (P<0.05). No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone, the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3, which is a potential “interception” point of the “Zhu Ke Jiao” theory.

ObjectiveAngelicae Sinensis Radix, a commonly used medicinal herb with both medicinal and edible properties, is frequently adulterated in the market, severely affecting the clinical efficacy of preparations. While qualitative identification techniques for adulterants and counterfeits are now relatively mature, quantitative detection methods for adulterated processed products remain unexplored. Quantitative detection research of Angelicae Sinensis Radix and its primary closely related adulterant, "Tu Danggui" (Angelica gigas), was conducted to establish a herbal quantitative molecular detection (Herb-Q) method for Angelicae Sinensis Radix and its processed products, providing a model for the establishment of quantitative detection technologies for Angelicae Sinensis Radix and related health products. MethodsThe specific single-nucleotide polymorphism (SNP) loci of Angelicae Sinensis Radix and Angelica gigas Nakai were screened based on the complete chloroplast genome sequence. The specific SNP loci of Angelicae Sinensis Radix were selected for quantitative methodological investigations (linearity, limit of quantification, limit of detection, and reproducibility) by mixing the powder of the herbs with different adulteration ratios. Huoxue Zhitong powder with three distinct adulteration ratios (15%, 25%, and 35%) was utilized to ascertain the precision of the Herb-Q method for the quantitative detection of Chinese patent medicines containing Angelicae Sinensis Radix. ResultsBy comparing the 123 chloroplast genome sequences of Angelicae Sinensis Radix, based on the principles of intraspecies conservation, interspecies specificity, and meeting the requirements of pyrophosphate high-throughput sequencing, it was determined that 9 674th locus (A/G) in the chloroplast genome sequence NC_042826.1 and 38 592nd locus (T/C) in the chloroplast genome sequence NC_029393.1 could be the exclusive molecular identification loci of Angelicae Sinensis Radix and Angelica gigas Nakai, respectively. The linear relationship R2 of the Herb-Q method established by selecting the specific 9 674th locus (A/G) of Angelicae Sinensis Radix was 0.997 4 (R2>0.99), indicating an excellent linear relationship. The limits of quantification and detection were established at 2.0%, exhibiting excellent reproducibility [relative standard deviation(RSD)<2.0%]. The established quantitative system based on the Herb-Q method detected the adulteration amount of counterfeit A. gigas in the Huoxue Zhitong powder, with an average deviation of 1.3% for three molecular quantitative replicates. ConclusionThis research demonstrates that the Herb-Q quantitative detection method established based on the 9 674th locus (A/G) in the chloroplast genome sequence NC_042826.1 of Angelicae Sinensis Radix has good applicability, objectivity, and accuracy for Angelicae Sinensis Radix and A. gigas, and its processed products. This method has the capacity to provide technical support for the quantitative detection of commercially available Angelicae Sinensis Radix derivatives, including traditional Chinese medicinal preparations, dietary supplements, and nutraceuticals.

Progress in Biochemistry and Biophysics 2026;53(3):609-622
Hepatocellular carcinoma (HCC) is a lethal cancer with high morbidity rates worldwide. It is a major threat to public health in China, due to the combination of known and new risk factors, such as endemic hepatitis B virus (HBV), dietary aflatoxin exposure, and the occurrence of metabolic dysfunction-associated steatotic liver disease (MASLD). Although many methods for surveillance and multimodal therapies, such as surgery, local ablation, transarterial therapy, and new systemic agents, have been available, the survival rates of HCC remains poor. They have very limited durable responses, long post-treatment recurrence rates, and high resistance to treatment. This reflects an imperfect picture of the biological cause of the disease and a need for new mechanistic or targeted techniques. A significant characteristic of HCC, in common with other aggressive cancers, is the presence of reprogrammed, hyperactive cell metabolism. Tumor cells hijack metabolic pathways to promote their uncontrolled growth, stress survival, invasion and metastasis. While classical mechanisms such as the Warburg effect, lipid metabolism and glutamine utilization have been understood, the lysosome, which was once viewed as a static “waste disposal unit” to remove old organelles and proteins, is instead a dynamic signaling and metabolic core. The lysosomes incorporate nutrients, energy and stress signals by master regulators such as mTORC1 (activated on its surface) that balance anabolic growth and catabolic recycling to the cellular demands. In HCC, lysosomes are not passive, but are highly active and dysregulated. HCC cells upregulate lysosomes, which scavenge intracellular components via enhanced autophagy and engulf extracellular proteins via macropinocytosis, crucial for survival in the nutrient-poor, hypoxic tumor microenvironment. In addition to metabolism, lysosomes exhibit pro-invasive functions by secreting hydrolases to remodel the extracellular matrix, promote angiogenesis, and suppress stromal immune cells to foster a pro-tumor microenvironment. In a clinical context, lysosomes play an important role in therapeutic resistance: they sequester and inactivate chemotherapeutics via lysosomal sequestration, and enhanced autophagic flux protects the cell from therapy-induced damage, contributing to relapse, as lysosomal dysfunction is a key cause of treatment failure. This makes lysosomes promising yet challenging therapeutic targets in HCC. Recent preclinical and early clinical studies investigate multiple strategies to exploit the susceptibility of lysosomes: lysosome-specific agents, alkalinizing the lysosome lumen or inducing membrane permeabilization and lysosome-dependent cell death; pharmacological inhibition of key lysosomal enzymes or autophagy to impair nutrient recycling and stress adaptation; smart nanotherapeutic agents or antibody-drug conjugates, specifically activated in the acidic lysosomal environment or utilizing lysosomal pathways for efficient intracellular drug release; and combination strategies of lysosome-targeting agents with tyrosine kinase inhibitors or immunotherapy to overcome resistance and achieve synergistic antitumor effects. In summary, our review systematically presents the role of lysosomes in HCC, from metabolic reprogramming and microenvironmental adaptation to therapeutic resistance. By synthesizing the latest mechanistic insights and preclinical advances, this review highlights the indispensable role of lysosomes in the complex HCC biological network, emphasizing that an in-depth understanding of this dynamic organelle holds great promise for developing innovative, targeted therapies, offering new hope for improving the poor prognosis of global HCC patients.

ObjectiveTo investigate the association between chronic liver disease (CLD) and depression and the mediating role of nocturnal sleep duration, as well as the consistency of this association between Chinese and American populations. MethodsThe data from two databases were integrated, i.e., China Health and Retirement Longitudinal Study (CHARLS) (n=14 225) in China and National Health and Nutrition Examination Survey (NHANES) (n=11 353) in the United States, and the subjects were divided into CLD group and non-CLD group. A stepwise Logistic regression model was used to assess the independent association between CLD and depression. Bootstrap resampling (1 000 times) was used to quantify the proportion of the mediating effect of nocturnal sleep duration, and interaction effects were evaluated through stratified analyses based on the factors including registered residence/race and income. The independent-samples t test was used for comparison of continuous data between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data; a multivariate Logistic regression model analysis was used to investigate the association of different types of CLD with depression. ResultsAfter multivariate adjustment, CLD was significantly associated with the increased risk of depression (CHARLS: odds ratio [OR]=1.76, 95% confidence interval [CI]: 1.46 — 2.12, P<0.001; NHANES: OR=1.87, 95%CI: 1.50 — 2.35, P<0.001). Nocturnal sleep duration played a partial mediating role in the association between CLD and depression, with a mediating effect accounted for 12.41% in CHARLS and 2.16% in NHANES (P<0.05). The interaction analysis showed that in CHARLS, the association between CLD and depression was more significant in the residents with agricultural registered permanent residence (OR=2.07, 95%CI: 1.67 — 2.57, P<0.001), and in NHANES, this association was more significant in the population with moderate poverty income ratio (OR=2.66, 95% CI: 1.92 — 3.69, P<0.001). The subtype analysis showed that autoimmune hepatitis (OR=3.63, 95%CI: 1.49 — 8.88, P=0.005), liver cirrhosis (OR=2.46, 95%CI: 1.32 — 4.60, P=0.005), and fatty liver disease (OR=1.75, 95%CI: 1.27 — 2.39, P=0.001) significantly increased the risk of depression, while no statistical significance was observed for viral hepatitis or other liver diseases (P>0.05). ConclusionThis study reveals the significant association between CLD and depression at the population level and suggests that nocturnal sleep duration may play a partial mediating role, which is consistent between the Chinese and American populations. These research findings provide quantitative evidence-based support for understanding the underlying mechanism of CLD-related depression and points out the potential significance of sleep issues in CLD management.

According to traditional Chinese medicine (TCM) theory, impaired spleen transportation function disrupts nutrient distribution, causing metabolic accumulation of lipids that transform into pathogenic phlegm-dampness. These pathological factors disseminate through the San Jiao and obstruct meridian pathways, ultimately forming the pathogenesis described as "all disorders involve phlegm". Phlegm and dampness share common pathogenic origins but manifest distinct clinical manifestations. Dampness, as the precursor, may congeal into phlegm, while existing phlegm accumulation can further exacerbate dampness stagnation, thereby establishing a self-perpetuating pathological cycle. Modern medical research has confirmed that the essence of "phlegm-dampness" syndrome is closely associated with energy metabolism disorders, serving as a common pathological basis for metabolic syndrome, type 2 diabetes mellitus, atherosclerosis, and other major chronic diseases. As a crucial vehicle for medical experimental research, disease-syndrome combination animal models serve as an indispensable means to advance the modernization of TCM. Currently, based on classical theories such as "rich and greasy foods produce phlegm" and "physical coldness combined with cold consumption causes external pathogens to invade the skin and hair, thereby generating internal dampness", researchers primarily employ two paradigms to construct animal models of phlegm-turbidity, dampness obstruction, and phlegm-dampness syndromes: the first involves simulating TCM etiological factors (through methods like dietary irregularities, imblanace between work and rest, and combined internal-external dampness exposure), while the second combines disease with syndrome differentiation (inducing pathological changes through physical, chemical, or biological interventions). Through comprehensive evaluation incorporating macroscopic observation and microscopic index detection, model animals undergo systematic biological and pathological assessment, with further syndrome type verification achieved via the "prescription-based syndrome detection" approach. However, existing models still exhibit significant deficiencies in both the standardization of modeling methodologies and the systematization of evaluation criteria. This paper reviews the strategies for constructing "phlegm-dampness" syndrome animal models and their corresponding evaluation indices, focusing on the pathological correlations among different modeling approaches. The aim is to provide methodological guidance for research on TCM syndromes related to "phlegm-dampness" syndrome and to support the development of TCM therapies for resolving phlegm and eliminating dampness. This study not only contributes to advancing the standardization of TCM syndrome research but also provides crucial technical support for the modernization of TCM.

ObjectiveThis paper aims to investigate the differential mechanisms underlying the staged therapeutic effects of Qijia Rougan formula on liver fibrosis using proteomic technology. MethodsThe staged rat model of liver fibrosis was established by subcutaneous injection of carbon tetrachloride (CCl4) and olive oil. One hundred and four SD rats were randomized into thirteen groups:a normal group,a two-week model group,a four-week model group,a six-week model group,an eight-week model group,a two-week Qijia Rougan formula group,a four-week Qijia Rougan formula group,a six-week Qijia Rougan formula group,an eight-week Qijia Rougan formula group,a two-week compound Biejia Ruangan tablet group,a four-week Compound Biejia Ruangan Tablet group,a six-week Compound Biejia Ruangan Tablet group,and an eight-week compound Biejia Ruangan tablet group. After two weeks of drug intervention,liver tissue and abdominal aortic blood samples were collected from the rats for testing. Hematoxylin-eosin (HE) staining,Masson staining,and Picro Sirius red staining were used to observe pathological damage and collagen fiber deposition in liver tissues. Immunohistochemistry (IHC) was employed to detect the contents of fibrosis markers in liver tissues. The contents of liver function indicators in the serum were measured using a fully automated biochemical analyzer,and the levels of liver fibrosis indicators in the serum were assessed by enzyme-linked immunosorbent assay (ELISA). Liver tissues from the normal group,each model group,and each Qijia Rougan formula group were subjected to label-free quantitative proteomic analysis to identify differential proteins among the groups,with key proteins validated by Western blot. Finally,bioinformatics analysis was performed on the differential proteins. Results(1) The staged rat model of liver fibrosis constructed with CCl4 and olive oil showed pathological results at the 2nd,4th,6th,and 8th weeks of modeling that were consistent with the Metavir standards for the F1,F2,F3,and F4 stages. Compared with those in the normal control group,the protein expressions of α-smooth muscle actin (α-SMA) and Collagen Ⅰ were significantly increased in each stage (P<0.05). The levels of liver function indicators in the serum,including alanine aminotransferase (ALT),aspartate aminotransferase (AST),alkaline phosphatase (ALP),direct bilirubin (DBIL),and total bilirubin (TBil) in each model group,were significantly elevated in each stage (P<0.01). The levels of liver fibrosis indicators in the serum,including procollagen Ⅲ peptide (PⅢP),type Ⅳ collagen(Ⅳ-C),hyaluronic acid (HA),and laminin (LN) in each model group,were significantly increased in each stage (P<0.05,P<0.01). This study successfully established a staged rat model of liver fibrosis. (2) Compared with the model groups at each stage,the administration groups showed a reduction in hepatocyte ballooning degeneration,a more orderly arrangement of hepatocytes,and a decrease of inflammatory cell infiltration. The blue-stained collagen fibers became significantly thinner and finer,with reduced and narrowed fibrous septa. The areas of collagen fibers and Picro Sirius red staining were reduced (P<0.05). The positive areas of α-SMA and Collagen Ⅰ expression were significantly decreased (P<0.05). The levels of ALT,AST,ALP,DBIL,and TBil in the rats of the model groups at each stage were significantly reduced (P<0.05,P<0.01). The levels of PⅢP,Ⅳ-C,HA,and LN in the rats of the model groups at each stage were significantly decreased (P<0.05). Among these,the improvements in all indicators were most significant in the F3 stage (P<0.01).(3) The proteomic results show that a total of 165 differential proteins exhibit a callback trend when comparing the model groups at four stages with the normal group,and when comparing the Qijia Rougan formula group with the model group. Western blot analysis reveals that the levels of NAD(P)H:quinone oxidoreductase 1 (NQO1),mitogen-activated protein kinase 1 (MAPK1),arginase 1 (Arg1),and glutathione S-transferase α1 (GSTA1) were consistent with the proteomic results. Bioinformatics results reveal that 165 differentially expressed proteins are enriched in multiple signaling pathways. Notably,signaling pathways such as drug metabolism-cytochrome P450,arginine biosynthesis,and the peroxisome proliferator-activated receptor (PPAR) signaling pathway were found to be closely associated with liver fibrosis,suggesting that the Qijia Rougan formula may exert its staged regulatory effects on liver fibrosis by regulating these pathways. ConclusionThe Qijia Rougan formula may achieve staged regulation of liver fibrosis by regulating drug metabolism-cytochrome P450,arginine biosynthesis,and the PPAR signaling pathway.

ObjectiveThis paper aims to investigate the potential molecular biological mechanism of Buyang Huanwu Tongfeng decoction in treating hyperuricemia and gouty arthritis by network pharmacology and molecular docking technology and preliminarily verify the mechanism through animal experiments. MethodsThe active ingredients and targets in the Buyang Huanwu Tongfeng decoction were obtained by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and ETCM databases. The DisGeNET and GeneCards databases were utilized to acquire disease targets associated with hyperuricemia and gouty arthritis. These disease targets were then intersected with drug targets to identify key targets. The R language ClusterProfiler package and Python were employed for conducting gene ontology(GO) enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) enrichment analysis. The regulatory network diagram of the drug-key target-function-pathway was visualized using Cytoscape 3.9.1 software, and the protein-protein interaction (PPI) network for key targets was depicted. Finally, the hub gene was determined through topological analysis. Auto Dock, PyMOL, and other software were used for molecular docking to explore the possible therapeutic mechanism of Buyang Huanwu Tongfeng decoction for hyperuricemia and gouty arthritis. In animal experiments, a composite rat model of hyperuricemia induced by intraperitoneal injection of oteracil potassium combined with gouty arthritis induced by the modified Coderre method was established. Through hematoxylin-eosin(HE) staining, uric acid test, enzyme linked immunosorbent assay(ELISA), Western blot, and real-time polymerase chain reaction(Real-time PCR), the molecular mechanism and key targets of Buyang Huanwu Tongfeng decoction for treating hyperuricemia and gouty arthritis were observed. ResultsAfter screening and removing duplicate values, 76 active ingredients and 15 key targets were finally obtained. GO enrichment analysis yielded that the treatment of hyperuricemia and gouty arthritis with Buyang Huanwu Tongfeng decoction was significantly associated with acute inflammatory response, astrocyte activation, regulation of interleukin (IL)-8 production, nuclear receptor activity, and binding of growth factor receptor. KEGG pathway enrichment analysis obtained that the key target genes were significantly associated with the IL-17 signaling pathway, advanced glycosylation end/receptor of advanced glycation endproducts(AGE/RAGE) signaling pathway, anti-inflammatory, and other pathways. PPI network indicated that albumin(ALB), peroxisome proliferator-activated receptor-γ (PPAR-γ), IL-6, IL-1β, and C-reactive protein(CRP) were the key protein targets. The molecular docking results showed that ALB had the strongest binding force with beta-carotene (β-carotene). Biochemical results showed that blood uric acid decreased in the Buyang Huanwu Tongfeng decoction groups. HE staining results showed that the low-dose (7.76 g·kg-1·d-1), medium-dose (15.53 g·kg-1·d-1), and high-dose (31.05 g·kg-1·d-1) groups of Buyang Huanwu Tongfeng decoction had different degrees of remission, and the remission of the high-dose group was the most obvious. Fibroblastic tissue hyperplasia in synovial joints accompanied with inflammatory cell infiltration, as well as inflammatory cell infiltration in renal tissue of the high-dose group was significantly reduced, followed by the medium-dose and low-dose groups, and the expression of ALB, PPAR-γ, IL-6, IL-1β, and CRP was down-regulated to different degrees. ConclusionBy regulating the targets such as ALB, PPAR-γ, IL-6, IL-1β, and CRP, inhibiting the PPAR-γ/nuclear transcription factor (NF)-κB pathway, and reducing AGEs/RAGE-mediated inflammation, Buyang Huanwu Tongfeng decoction exerts anti-inflammatory and analgesic effects and activates blood circulation and diuresis in the treatment of hyperuricemia and gouty arthritis.
