OBJECTIVE To investigate the therapeutic effect and mechanism of Qiwei dongqingye powder (QDP) on bronchial asthma in mice. METHODS The mice were divided into blank group (normal saline), model group (normal saline), dexamethasone group (2 mg/kg), and QDP low-, medium-, and high-dose groups (200, 400, 800 mg/kg), with 14 mice in each group. Except for the blank group, mice in all other groups were given ovalbumin via intraperitoneal injection followed by aerosol inhalation to induce a bronchial asthma model. During the modeling process, mice in each group were administered corresponding drug solutions or normal saline intragastrically/intraperitoneally. After the last medication, the number of cells in the bronchoalveolar lavage fluid (BALF) of the mice was observed and counted; the pathological changes of the bronchus and lung tissue were observed; the levels of malondialdehyde (MDA), nitric oxide (NO), total superoxide dismutase (T-SOD), and glutathione peroxidase (GSH-Px) in the lung tissue of the mice were determined, and the level of interleukin-17 (IL-17) in the BALF and serum was determined. Transcriptomics was employed to predict and validate the mechanism of action of QDP against bronchial asthma. RESULTS Compared with the model group, the total cell count, neutrophil count, lymphocyte count, and macrophage counts in the BALF of the QDP high-dose group were all significantly reduced ( P <0.05); the levels of MDA and NO in the lung tissue, and the levels of IL-17 in the BALF and serum were all decreased significantly ( P <0.05); the levels of T-SOD and GSH-Px were significantly increased ( P <0.05); the arrangement of lung tissue cells tended to normalize, with reduced infiltration of inflammatory cells and decreased exfoliation of bronchial simple columnar epithelial cells. The transcriptomic results revealed that the differentially expressed genes were B-cell receptor signaling pathway, nuclear factor κB (NF-κB) signaling pathway, ferroptosis signaling pathway, and others. Further validation revealed that, compared with the model group, the expression levels of NF-κB p65 and chemokine ligand 20, as well as the phosphorylation level of NF-κB inhibitor protein α, were significantly decreased in the lung tissues of the mice in all QDP groups ( P <0.05). Conversely, the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase 1 (HO-1) were significantly increased ( P <0.05). CONCLUSIONS QDP can effectively alleviate bronchial asthma by inhibiting the NF-κB signaling pathway, activating the Nrf2/HO-1 signaling pathway, regulating oxidative stress, and reducing inflammatory responses.

ObjectiveColorectal cancer (CRC) is a highly heterogeneous malignancy, and traditional Chinese medicine (TCM) syndrome differentiation is widely used in its clinical management. However, the biological basis underlying different TCM syndromes remains insufficiently understood. This study aimed to investigate the proteomic differences between qi-blood deficiency syndrome (QBDS) and damp-heat syndrome (DHS) in CRC patients and to establish a “syndrome-differential protein-herbal component” network for exploring potential molecular mechanisms and therapeutic targets associated with syndrome-specific treatment strategies. MethodsTumor tissue samples were collected from 10 patients with pathologically confirmed CRC, including 5 patients diagnosed with QBDS and 5 with DHS according to standardized TCM syndrome differentiation criteria. Tandem mass tag (TMT)-based quantitative proteomics was employed to identify differentially expressed proteins (DEPs) between the two syndrome groups. Functional enrichment analyses, including Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses, were performed to characterize the biological functions and signaling pathways associated with the identified DEPs. Least absolute shrinkage and selection operator (LASSO) regression analysis was further applied to screen key syndrome-related proteins and construct a core protein prediction model. Subsequently, molecular docking was conducted to evaluate the binding affinities between representative herbal compounds, astragaloside IV and berberine, and the identified core proteins. Finally, cell counting kit-8 (CCK-8) assays were performed in HCT 116 and HT-29 colorectal cancer cell lines to validate the anti-proliferative activities of these compounds in vitro. ResultsA total of 44 DEPs were identified between QBDS and DHS tissues, including 21 upregulated and 23 downregulated proteins in the QBDS group relative to the DHS group. Functional enrichment analyses revealed that these proteins were primarily associated with antiviral immune responses, regulation of inflammatory signaling, NF‑κB signaling pathways, cholesterol metabolism, and other biological processes relevant to tumor progression and host immune regulation. LASSO regression analysis identified eight core proteins with potential syndrome-specific significance. Among them, ST7, GPCPD1, and PODXL were closely associated with QBDS, whereas FAT1, GRB7, KRT7, MAFF, and MMP8 were associated with DHS. Molecular docking demonstrated favorable interactions between astragaloside IV and QBDS-related proteins, with binding energies lower than -5 kcal/mol, indicating stable binding activity. Berberine exhibited even lower binding energies and stronger binding specificity toward DHS-related core proteins. In vitro experiments further confirmed that both compounds inhibited CRC cell proliferation, while berberine displayed significantly greater anti-proliferative efficacy. The lowest 48 h IC50 value of berberine reached 15.21 mg/L in CRC cells, indicating a stronger growth-inhibitory effect than astragaloside IV. ConclusionCRC patients with QBDS and DHS exhibit distinct proteomic characteristics, suggesting that different TCM syndromes possess unique molecular signatures. The identified core proteins may serve as potential biomarkers for syndrome differentiation, while astragaloside IV and berberine may exert therapeutic effects through targeting syndrome-specific molecular networks. These findings provide preliminary proteomic evidence supporting syndrome-guided precision integrative medicine in CRC and offer new insights into the biological basis of TCM syndrome differentiation and individualized therapeutic strategies.

ObjectiveTo explore the mechanism by which Xianglian Huazhuo prescription ameliorates chronic atrophic gastritis (CAG) through regulating the Golgi protein 73 (GP73)/protein kinase R-like endoplasmic reticulum kinase (PERK)/activating transcription factor 4 (ATF4) signaling pathway and modulating endoplasmic reticulum stress (ERS). MethodA mouse model of CAG was induced by multiple factors, including ranitidine, N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), and irregular feeding. The CAG mice were randomized into five groups: model, Morodan (2.0 g·kg-1), and high-dose, medium-dose, and low-dose (7.6, 3.8, 1.9 g·kg-1, respectively) Xianglian Huazhuo prescription, with 10 mice in each group. At the same time, 10 mice in normal group were set up. The mice in the Morodan group and the high-dose, medium-dose, and low-dose groups of Xianglian Huazhuo prescription were administrated with corresponding agents by gavage, and those in the normal group and the model group were administrated with an equal volume of normal saline. All the mice were intervened once a day for 60 consecutive days. After the last administration, the overall morphological changes of the gastric tissue were observed. Hematoxylin-eosin (HE) staining and transmission electron microscopy (TEM) were used to evaluate the pathological morphology and the endoplasmic reticulum ultrastructure in the gastric tissue. The serum levels of pepsinogen Ⅰ (PGⅠ), pepsinogen Ⅱ (PGⅡ), gastrin-17 (G-17), and GP73 were determined by enzyme-linked immunosorbent assay (ELISA). The pepsinogen ratio (PGR, PGⅠ/PGⅡ) was calculated. The protein levels of GP73, PERK, phosphorylated (p)-PERK, glucose-regulated protein 78 (GRP78), ATF4, CCAAT enhancer-binding protein homologous protein (CHOP), cysteinyl aspartate-specific protease-12 (Caspase-12), B-cell lymphoma-2 (Bcl-2), and Bcl-2-associated X protein (Bax) were assessed by Western blot. The expression of GRP78 was detected by immunofluorescence (IF) assay, and the location of Bcl-2 and Bax by immunohistochemistry (IHC). ResultsCompared with the normal group, the model group showed pale gastric mucosa with flattened folds and reduced and loosely arranged gastric mucosal glands, declined serum levels of PGI, PGR, G-17, and GP73 (P<0.01). downregulated protein levels of GP73, p-PERK, ATF4, GRP78, CHOP, Caspase-12, and Bax in the gastric tissue, and upregulated protein level of Bcl-2 (P<0.01). Compared with the model group, the Morodan group and each Xianglian Huazhuo prescription group exhibited red gastric mucosa with increased folds, alleviated pathological damage, swelling endoplasmic reticulum, elevated serum levels of PGI, G-17, and GP73 (P<0.05, P<0.01), and upregulated protein levels of Caspase-12 and Bax and downregulated protein level of Bcl-2 in the gastric tissue (P<0.05, P<0.01). The Morodan group and the high-dose and medium-dose Xianglian Huazhuo prescription groups exhibited increased serum level of PGR (P<0.05, P<0.01) and upregulated protein levels of GP73, p-PERK, ATF4, GRP78, and CHOP in the gastric tissue (P<0.05, P<0.01). ConclusionXianglian Huazhuo prescription can activate the GP73/PERK/ATF4 signaling pathway and induce ERS-mediated apoptosis to alleviate the pathological damage of the gastric mucosa, thereby demonstrating a protective effect against CAG in mice.

ObjectiveTo investigate the therapeutic effect of paeoniflorin on metabolic dysfunction-associated fatty liver disease (MASLD) combined with insulin resistance (IR), and to elucidate its regulatory mechanisms on the Toll-like receptor 4 (TLR4)/nuclear transcription factor (NF)-κB-insulin receptor substrate 1 (IRS1) inflammation-insulin signaling axis. MethodsMASLD mouse model was established using a 60% high-fat diet. Mice were randomly assigned to a normal control group, a MASLD model group, and paeoniflorin groups (low dose: 25 mg·kg-1·d-1, medium dose: 50 mg·kg-1·d-1, high dose: 100 mg·kg-1·d-1), receiving intragastric administration for consecutive 12 weeks. Concurrently, a palmitic acid/oleic acid (PA/OA)-induced lipid deposition model was established in HepG2 cells. Cell counting kit-8 (CCK-8) assay was performed to determine the optimal concentrations of PA/OA and paeoniflorin for intervention. Mice body weight, liver index, and serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglycerides (TG), and total cholesterol (TC) were measured. Fasting blood glucose (FBG) and fasting insulin (FINS) levels were measured, and the homeostatic model assessment of insulin resistance (HOMA-IR) was calculated, while an oral glucose tolerance test (OGTT) was performed to evaluate glucose metabolism. Hematoxylin and eosin (HE) staining was used to observe pathological changes and inflammatory cell infiltration in liver tissue, and oil red O staining was used to evaluate lipid droplet deposition in liver tissue and HepG2 cells. Potential targets were screened using network pharmacology and molecular docking. Western blot analysis was performed to detect the expression of HSP90AA1, TLR4, p-NF-κB p65, p-IRS1, and p-Akt proteins in liver tissue and HepG2 cells. ResultsCompared with the normal control group, mice in the MASLD model group exhibited significantly increased body weight, liver index, and serum levels of ALT, AST, TG, and TC, as well as markedly elevated FBG, FINS, and HOMA-IR, and impaired glucose tolerance (P<0.01). HE staining revealed marked hepatic steatosis and inflammatory cell infiltration, while oil red O staining showed a significant increase in lipid droplet deposition. Compared with the MASLD model group, after intervention with various doses of paeoniflorin, the increase in body weight and liver index was reduced, serum ALT, AST, TG, and TC levels decreased, and FBG, FINS, and HOMA-IR were significantly lowered, with glucose tolerance markedly improved (P<0.05, P<0.01), showing a certain dose-dependent trend. HE and oil red O staining results showed a marked reduction in hepatic steatosis and lipid deposition. In vitro experiments demonstrated that, compared with the control group, PA/OA treatment significantly induced increased lipid deposition in HepG2 cells. Compared with the model group, paeoniflorin intervention significantly reduced intracellular lipid droplets, and lipid deposition showed a dose-dependent decreasing trend. Mechanism studies indicated that, compared with the normal control group, the MASLD model group exhibited significantly elevated expression of TLR4, HSP90AA1, and p-NF-κB p65, while p-IRS1 (Ser307) expression was elevated and p-Akt (Ser473) expression was reduced (P<0.01). Compared with the model group, the expression of the aforementioned proteins was significantly reversed in all treatment groups following intervention (P<0.05, P<0.01). ConclusionPaeoniflorin significantly alleviates lipid deposition and insulin resistance in MASLD mice. Its mechanism of action may involve targeting HSP90AA1, TLR4, and NF-κB1 to regulate the TLR4/NF-κB-IRS1 inflammation-insulin signaling axis. This regulation suppresses inflammatory responses and restores insulin signaling, thereby ameliorating abnormalities in glucose and lipid metabolism.

ObjectiveThis study aimed to investigate whether dexmedetomidine (Dex) alleviates stress-induced mammary tumor progression in mice by inhibiting the TLR4/NF‑κB signaling pathway, and to examine its effects on anxiety‑depression‑like behaviors and stress hormone levels. MethodsAn orthotopic EMT6 mammary tumor model was established in mice, and chronic mild stress (CMS) was applied to induce anxiety‑depression‑like states. The mice were divided into six groups: naive, tumor, CMS, CMS+tumor, CMS+tumor+Dex, and CMS+tumor+Vehicle groups. Behavioral changes were evaluated using the open field test and tail suspension test. Plasma stress hormone levels were measured by high‑performance liquid chromatography. Western blot and RT‑qPCR were performed to detect the expression of TLR4, p‑NF‑κB p65, p‑IκBα, and inflammatory cytokines (IL‑6, IL‑1β, TNF‑α) in tumor tissues. In vitro, EMT6 cells were treated with cortisol to mimic the stress-related microenvironment, and the effects of Dex on the TLR4/NF‑κB pathway were assessed by CCK‑8, Western blot, and RT-qPCR. ResultsTumor‑bearing mice exhibited significant anxiety‑depression‑like behaviors (P<0.05), along with markedly elevated plasma levels of norepinephrine, epinephrine, and cortisol (P<0.05). Chronic stress further aggravated these behavioral abnormalities and promoted tumor growth (P<0.05). Dexmedetomidine intervention significantly improved anxiety‑depression‑like behaviors (P<0.05) and lowered peripheral stress hormone levels (P<0.05) in stress‑exposed tumor‑bearing mice. In vitro experiments demonstrated that cortisol treatment activated the TLR4/NF‑κB pathway (P<0.001) and upregulated the expression of inflammatory cytokines (P<0.05 in EMT6 cells, whereas dexmedetomidine effectively suppressed this activation (P<0.001). In the in vivo model, dexmedetomidine treatment downregulated the expression of TLR4, p‑NF‑κB p65, p‑IκBα, and pro‑inflammatory cytokines in tumor tissues (P<0.001) and significantly inhibited tumor growth (P<0.05). ConclusionDexmedetomidine inhibits the TLR4/NF‑κB signaling pathway, alleviates stress‑induced inflammatory responses, improves anxiety- and depression‑ like behaviors, reduces stress hormone levels, and suppresses mammary tumor progression. These findings provide an experimental basis for understanding anxiety- and depression- associated breast tumor progression and suggest that Dexmedetomidine and the TLR4/NF-κB pathway may serve as potential therapeutic targets.

Diabetic nephropathy belongs to diabetic microvascular aseptic inflammation, which is the main cause of end-stage renal disease and can cause damage to the structure of glomeruli and tubulointerstitium. Pyroptosis is a potent pro-inflammatory model of programmed cell death mediated by gasdermin (GSDM) protein family, which is characterized by nuclear shrinkage, chromatin DNA fragmentation, plasma membrane rupture, cell swelling and deformation. Related studies have found that pyroptosis is closely related to the occurrence and development of diabetic nephropathy. Inhibition of pyroptosis to a certain extent can reduce diabetic renal injury, so the pathway of pyroptosis involved in the pathogenesis of diabetic nephropathy is the current research focus. The characteristics of multi-components, multi-targets and multi-pathways of traditional Chinese medicine have significant advantages in the treatment of diabetic nephropathy. Some components of traditional Chinese medicine, single traditional Chinese medicine and compound prescription of traditional Chinese medicine can improve diabetic renal injury by inhibiting pyroptosis pathway and related targets. Based on the molecular mechanism of pyroptosis, this paper clarifies the mechanism of pyroptosis in diabetic nephropathy by expounding the relationship between pyroptosis and its pathway targets and diabetic nephropathy. This paper summarizes the research status of traditional Chinese medicine in the treatment of diabetic nephropathy by interfering with related pyroptosis pathways in recent years, so as to provide perspectives and ideas for the prevention, early diagnosis, drug development and molecular treatment of diabetic nephropathy in the future.

Background/Aims:
Endoscopic radiofrequency ablation (ERFA) is a treatment option for superficial esophageal squamous cell neoplasia (ESCN), with a relatively low risk of stenosis; however, the long-term outcomes remain unclear. We aimed to compare the long-term outcomes of patients with widespread superficial ESCN who underwent endoscopic submucosal dissection (ESD) or ERFA.
Methods:
We retrospectively analyzed the clinical data of patients with superficial ESCN who underwent ESD or ERFA between January 2015 and December 2021. The primary outcome measure was recurrence-free survival.
Results:
Ninety-two and 33 patients with superficial ESCN underwent ESD and ERFA, respectively. The en bloc, R0, and curative resection rates for ESD were 100.0%, 90.2%, and 76.1%, respectively. At 12 months, the complete response rate was comparable between the two groups (94.6% vs 90.9%, p=0.748). During a median follow-up of 66 months, recurrence-free survival was significantly longer in the ESD group than in the ERFA group (p=0.004), while no significant differences in overall survival (p=0.845) and disease-specific survival (p=0.494) were observed.Preoperative diagnosis of intramucosal cancer (adjusted hazard ratio, 5.55; vs high-grade intraepithelial neoplasia) was an independent predictor of recurrence. Significantly fewer patients in the ERFA group experienced stenosis compare to ESD group (15.2% vs 38.0%, p=0.016).
Conclusions
The risk of recurrence was higher for ERFA than ESD for ESCN but overall survival was not affected. The risk of esophageal stenosis was significantly lower for patients who underwent ERFA.

Objective:
This study investigated the value of multiparametric MRI (mpMRI) in predicting Gleason score (GS) upgrading and downgrading in radical prostatectomy (RP) compared with presurgical biopsy.
Materials and Methods:
Clinical and mpMRI data were retrospectively collected from 219 patients with prostate disease between January 2015 and December 2021. All patients underwent systematic prostate biopsy followed by RP. MpMRI included conventional diffusion-weighted and dynamic contrast-enhanced imaging. Multivariable logistic regression analysis was performed to analyze the factors associated with GS upgrading and downgrading after RP. Receiver operating characteristic curve analysis was used to estimate the area under the curve (AUC) to indicate the performance of the multivariable logistic regression models in predicting GS upgrade and downgrade after RP.
Results:
The GS after RP was upgraded, downgraded, and unchanged in 92, 43, and 84 patients, respectively. The AUCs of the clinical (percentage of positive biopsy cores [PBCs], time from biopsy to RP) and mpMRI models (prostate cancer [PCa] location, Prostate Imaging Reporting and Data System [PI-RADS] v2.1 score) for predicting GS upgrading after RP were 0.714 and 0.749, respectively. The AUC of the combined diagnostic model (age, percentage of PBCs, tPSA, PCa location, and PIRADS v2.1 score) was 0.816, which was larger than that of the clinical factors alone (P < 0.001). The AUCs of the clinical (age, percentage of PBCs, ratio of free/total PSA [F/T]) and mpMRI models (PCa diameter, PCa location, and PI-RADS v2.1 score) for predicting GS downgrading after RP were 0.749 and 0.835, respectively. The AUC of the combined diagnostic model (age, percentage of PBCs, F/T, PCa diameter, PCa location, and PI-RADS v2.1 score) was 0.883, which was larger than that of the clinical factors alone (P < 0.001).
Conclusion
Combining clinical factors and mpMRI findings can predict GS upgrade and downgrade after RP more accurately than using clinical factors alone.
