OBJECTIVE To explore the mechanism of improvement effect of Chanbao zhichuang suppository (CBZCS) on hemorrhoids in rats through network pharmacology and metabolomics. METHODS A hemorrhoid model was established by subcutaneous injection of rhododendron oil to induce anal swelling. SD rats were divided into blank group (NC group, 0.32 g/kg vaseline), model group (Model group, 0.32 g/kg vaseline), CBZCS low-, medium-, and high-dose groups (CBZCS-L, CBZCS- M, CBZCS-H groups, with dosages of 0.16, 0.32, and 0.64 g/kg respectively), and Mayinglong musk hemorrhoids suppository group (Positive group, 0.32 g/kg), with 9 rats in each group. Anal administration was performed at 6, 12, 24, 48, and 72 hours after modeling. After the last administration, the pathological changes of the anal tissues in rats were observed, and the serum levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) in rats were detected. Differential metabolite analysis and enrichment analysis were conducted by metabolomics methods, and the target proteins of CBZCS in treating hemorrhoids were obtained by network pharmacology. The core metabolic pathways were screened by interaction and enrichment analysis of differential metabolites and proteins, and the core proteins were experimentally verified. RESULTS Compared with the NC group, the anal tissues of the Model group showed obvious lesions, and the levels of IL-6 and TNF- α in the serum were significantly increased (P<0.05); compared with the Model group, the pathological damage of the anal tissues in the treatment groups was alleviated to varying degrees, and serum levels of IL-6 in CBZCS-H group, CBZCS-M group, and Positive group as well as serum levels of TNF-α in CBZCS-H group were significantly reduced (P<0.05). The metabolomics results showed that 34 differential metabolites were screened from the anal tissues of rats, and 22 of them showed a return after CBZCS administration. The differential metabolites mainly enriched in arachidonic acid metabolism, histidine metabolism, and glycerophospholipid metabolism. Through the network pharmacology, 138 intersection genes of CBZCS against hemorrhoids were determined. The analysis results showed that differential metabolites and target proteins were mainly enriched in the arachidonic acid metabolism pathway, and the regulation of this pathway might be related to cyclooxygenase-2 (COX-2), Myc proto-oncogene protein (c-MYC), cytochrome P450 1B1 (CYP1B1), interleukin-1β (IL-1β), and IL-6 protein expression. The experimental verification results showed that the expression levels of key proteins (COX-2, c-MYC, CYP1B1, IL-6, IL-1β) in the anal tissues of the Model group were significantly higher than those in the NC group (P<0.05), and the levels of the above proteins in the anal tissues of CBZCS-H group and Positive group were significantly lower than those in the Model group (P<0.05). CONCLUSIONS The mechanism of CBZCS in treating hemorrhoids may be to inhibit the expression of COX-2, c-MYC and CYP1B1 proteins, thereby inhibiting arachidonic acid metabolism and reducing the release of inflammatory factors IL-6 and IL-1β.

Chinese Journal of School Health 2025;46(8):1125-1129
Objective:
To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality.
Methods:
From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two.
Results:
The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05).
Conclusions
Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

ObjectiveThis study aims to explore the neurotoxicity mechanism of Dictamni Cortex by integrating network toxicology and metabolomics techniques. MethodsThe neurotoxicity targets induced by Dictamni Cortex were screened by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Traditional Chinese Medicine Information Database (TCM-ID), and Comparative Toxicogenomics Database (CTD). The target predictions of the components were performed by the Swiss Target Prediction tool. Neurotoxicity-related targets were collected from the Pharmacophore Mapping and Potential Target Identification Platform (PharmMapper), GeneCards Human Gene Database (GeneCards), DisGeNET Disease Gene Network (DisGeNET), and Online Mendelian Inheritance in Man (OMIM), and the intersection targets were identified. Protein-protein interaction (PPI) analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis, and Gene Ontology (GO) enrichment analysis were conducted. A "drug-compound-toxicity target-pathway" network was constructed via Cytoscape software to display the core regulatory network. Based on the prediction results, the neurotoxicity mechanism of Dictamni Cortex in mice was verified by using hematoxylin-eosin (HE) staining, Nissl staining, enzyme-linked immunosorbent assay (ELISA), quantitative real-time fluorescence polymerase chain reaction (Real-time PCR), and Western blot. The effects of Dictamni Cortex on the metabolic profile of mouse brain tissue were further explored by non-targeted metabolomics. ResultsNetwork toxicology screening identified 13 compounds and 175 targets in Dictamni Cortex that were related to neurotoxicity. PPI network analysis revealed that serine/threonine-protein kinase (Akt1) and tumor protein 53 (TP53) were the core targets. Additionally, GO/KEGG enrichment analysis indicated that Dictamni Cortex may regulate the phosphatidylinositol 3-kinase (PI3K)/Akt pathway and affect oxidative stress and cell apoptosis, thereby inducing neural damage. The "Dictamni Cortex-compound-toxicity target-pathway-neural damage" network showed that dictamnine, phellodendrine, and fraxinellone may be the toxic compounds. Animal experiments showed that compared with those in the blank group, the hippocampal neurons in the brain tissue of mice treated with Dictamni Cortex were damaged. The level of superoxide dismutase (SOD) and acetylcholine (ACh) in the brain tissue was significantly reduced, while the content of malondialdehyde (MDA) was significantly increased. The level of Akt1 and p-Akt1 mRNAs and proteins in the brain tissue was significantly decreased, while the level of TP53 was significantly increased. Non-targeted metabolomics results showed that Dictamni Cortex could disrupt the level of 40 metabolites in mouse brain tissue, thereby regulating the homeostasis of 13 metabolism pathways, including phenylalanine, glycerophospholipid, and retinol. Combined analysis revealed that Akt1, p-Akt1, and TP53 were significantly correlated with phenylalanine, glycerophospholipid, and retinol metabolites. This suggested that Dictamni Cortex induced neurotoxicity in mice by regulating Akt1, p-Akt1, and TP53 and further modulating the phenylalanine, glycerophospholipid, and retinol metabolism pathways. ConclusionDictamni Cortex can induce neurotoxicity in mice, and its potential mechanism may be closely related to the activation of oxidative stress, inhibition of the PI3K/Akt signaling pathway, and regulation of phenylalanine, glycerophospholipid, and retinol metabolism pathways.

ObjectiveThis study aims to investigate the effect of Dictamni Cortex on intestinal barrier damage in rats and its mechanism by untargeted metabolomics and targeted metabolomics for short-chain fatty acids (SCFAs). MethodsRats were randomly divided into a control group, a high-dose group of Dictamni Cortex (8.1 g·kg-1), a medium-dose group (2.7 g·kg-1), and a low-dose group (0.9 g·kg-1). Except for the control group, the other groups were administered different doses of Dictamni Cortex by gavage for eight consecutive weeks. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in the ileal tissue. Enzyme-linked immunosorbent assay (ELISA) was employed to detect the level of cytokines, including tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β), in the ileal tissue of rats. Quantitative real-time fluorescence polymerase chain reaction (Real-time PCR) technology was used to detect the expression level of tight junction proteins, including zonula occludens-1 (ZO-1), Occludin, and Claudin-1 mRNAs, in the ileal tissue of rats to preliminarily explore the effects of Dictamni Cortex on intestinal damage. The dose with the most significant toxic phenotype was selected to further reveal the effects of Dictamni Cortex on the metabolic profile of ileal tissue in rats by non-targeted metabolomics combined with targeted metabolomics for SCFAs. ResultsCompared with the control group, all doses of Dictamni Cortex induced varying degrees of pathological damage in the ileum, increased TNF-α (P<0.01), IL-6 (P<0.01), and IL-1β (P<0.01) levels in the ileal tissue, and decreased the expression level of ZO-1 (P<0.05, P<0.01), Occludin (P<0.01), and Claudin-1 (P<0.05) in the ileal tissue, with the high-dose group showing the most significant toxic phenotypes. The damage mechanisms of the high-dose group of Dictamni Cortex on the ileal tissue were further explored by integrating non-targeted metabolomics and targeted metabolomics for SCFAs. The non-targeted metabolomics results showed that 21 differential metabolites were identified in the control group and the high-dose group. Compared with that in the control group, after Dictamni Cortex intervention, the level of 14 metabolites was significantly increased (P<0.05, P<0.01), and the level of seven metabolites was significantly decreased (P<0.05, P<0.01) in the ileal contents. These metabolites collectively acted on 10 related metabolic pathways, including glycerophospholipids and primary bile acid biosynthesis. The quantitative data of targeted metabolomics for SCFAs showed that Dictamni Cortex intervention disrupted the level of propionic acid, butyric acid, acetic acid, caproic acid, isobutyric acid, isovaleric acid, valeric acid, and isocaproic acid in the ileal contents of rats. Compared with those in the control group, the level of isobutyric acid, isovaleric acid, and valeric acid were significantly increased, while the level of propionic acid, butyric acid, and acetic acid were significantly decreased in the ileal contents of rats after Dictamni Cortex intervention (P<0.05, P<0.01). ConclusionDictamni Cortex can induce intestinal damage by regulating glycerophospholipid metabolism, primary bile acid biosynthesis, and metabolic pathways for SCFAs.

ObjectiveThis study aims to reveal the mechanism of liver and kidney injuries caused by Dictamni Cortex and its interrelationship by metabonomics analysis of liver and kidney via ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS). MethodsThe content of the marker compounds of Dictamni Cortex was measured by high-performance liquid chromatography (HPLC) to carry out quality control. Sprague Dawley (SD) rats were randomly divided into a blank group (normal saline), an administration group (0.9, 2.7, 8.1 g·kg-1), and a high-dose withdrawal control group, with eight rats in each group. Continuous administration was performed once daily for 28 days. The liver and kidney injuries caused by each administration group were assessed by organ indices, pathological observations, and serum and plasma biochemical indices measured by enzyme-linked immunosorbent assay (ELISA). The potential biomarkers of liver and kidney injuries caused by Dictamni Cortex were screened, and pathway enrichment analysis and correlation analysis were performed based on UPLC-Q-TOF-MS. ResultsCompared with the blank group, both the medium- and low-dose groups showed insignificant damage to the liver and kidney of rats. The high-dose group exhibited the most serious damage, and the level of liver and kidney function indices [alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr), and blood urea nitrogen (BUN)] and serum inflammatory indices ([interleukin 1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α)] in the serum were significantly changed (P<0.01). The liver and kidney metabolism pathways and differential metabolites were quite different. Among them, phenylalanine metabolism, niacin and nicotinamide metabolism, and glycerophospholipid metabolism were common pathways. Correlation analysis of differential metabolites showed that there were significant correlations among disorders of 4′-Phosphopantothenoylcysteine, PC (16∶0/15∶0), phenylethylamine, arachidonic acid, and linoleic acid in liver and kidney tissue. ConclusionThe decoction of Dictamni Cortex can cause liver and kidney injuries, and its mechanism may be related to oxidative stress and lipid metabolism disorders. The correlation of differential metabolites indicates the interaction between liver and kidney injuries.

ObjectiveTo explore the mechanism of the immunotoxicity induced by dictamnine (DIC) in rats and the recovery effect after drug withdrawal by ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry, thereby providing a theoretical basis for elucidating the toxic mechanism of DIC. MethodsSD rats were randomized into blank (normal saline), DIC (10 mg·kg-1), and DIC withdrawal (recovery period) groups (n=8). The rats were continuously treated for 7 days, once a day, and the body weight and organ weight were recorded. The levels of interleukin-1 (IL-1), IL-6, and tumor necrosis factor-α (TNF-α) in the serum and immunoglobulin A (IgA), immunoglobulin G (IgG), and immunoglobulin M (IgM) in the spleen were determined by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was used to observe the pathological changes in the spleen. ultra performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was employed to screen the potential biomarkers of immune inflammation caused by DIC, and pathway enrichment analysis and correlation analysis were performed. The mRNA levels of IL-1β, TNF-α, lysophosphatidylcholine acyltransferase 2 (LPCAT2), and farnesoid X receptor (FXR) in the serum were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with the blank group, the DIC group showed elevated levels of IL-1β, IL-6, and TNF-α in the serum (P<0.01), and the DIC withdrawal group showcased lowered levels of IL-1β, IL-6, and TNF-α in the serum (P<0.01). The levels of IgA, IgG, and IgM in the spleen of rats in the DIC group were decreased (P<0.01), while those in the DIC withdrawal group were recovered (P<0.05, P<0.01). Untargeted metabolomics of the serum and spleen screened out 14 common differential metabolites and 14 common metabolic pathways. The Spearman correlation analysis between differential metabolites and inflammatory factors identified PC (32∶0), LysoPC (20∶4/0∶0), LysoPC (P-18∶0/0∶0), taurochenodeoxycholic acid, taurocholic acid, LysoPC [20∶5(5Z,8Z,11Z,14Z,17Z)/0∶0], chenodeoxycholic acid, arachidonic acid, LysoPC (18∶0/0∶0), LysoPC (15∶0/0∶0), LysoPC (16∶0/0∶0), and LysoPC (17∶0/0∶0) as the biomarkers of immunotoxicity induced by DIC in SD rats. In the process of immunotoxicity caused by DIC, lipid metabolism disorders such as glycerophospholipid metabolism, primary bile acid metabolism, and arachidonic acid metabolism were enriched, which was consistent with the DIC-induced inflammatory factors and pathological characteristics of the spleen. Compared with the blank group, the DIC group exhibited up-regulated mRNA levels of IL-1β, TNF-α, LPCAT2, and FXR (P<0.01), and the up-regulation was decreased in the withdrawal group (P<0.01). ConclusionDIC can lead to immune and inflammatory disorders. DIC withdrawal can regulate the expression of biomarkers related to serum and spleen metabolites, regulate the inflammatory metabolic pathway, reduce the inflammation level, and alleviate the metabolic disorders, thus attenuating the potential toxicity induced by DIC.

ObjectiveTo explore the mechanism of action of Wuwei Shenqintang in improving pulmonary fibrosis by using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) for metabolomic analysis of lung tissue and feces. MethodsA rat model with pulmonary fibrosis was established by intratracheal injection of 5 mg·kg-1 bleomycin. The successfully modeled rats were randomly divided into a blank group, a model group, a prednisone (3.15 mg·kg-1) group, and low-dose, medium-dose, and high-dose groups of Wuwei Shenqintang (4.586, 9.172, 18.344 g·kg-1). The rats were given intragastric administration once a day for 28 consecutive days. Hematoxylin-eosin (HE) staining was used to measure the pathological changes in lung and colon tissue, and Masson staining was used to detect the degree of pulmonary fibrosis. Enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of interleukin-1β (IL-1β), IL-6, IL-8, tumor necrosis factor-α (TNF-α), and secretory immunoglobulin A (SIgA) in bronchoalveolar lavage fluid and intestinal mucus. Immunohistochemistry and reverse transcription quantitative polymerase chain reaction (Real-time PCR) were used to detect the expression of type Ⅰ collagen (Col-Ⅰ), fibronectin (FN), and alpha smooth muscle actin (α-SMA) in lung tissue. UPLC-Q-TOF-MS was used to study the changes in the metabolic network of lung tissue and feces in rats with pulmonary fibrosis treated with Wuwei Shenqintang, screen potential biomarkers for the treatment of pulmonary fibrosis by Wuwei Shenqintang, and perform pathway enrichment analysis. ResultsCompared with the blank group, the model group showed extensive inflammatory cell infiltration and continuous fibrotic lesions in lung tissue, colonic mucosal damage, and connective tissue hyperplasia. The expression of IL-6, IL-8, IL-1β, TNF-α, and SIgA in bronchoalveolar lavage fluid and intestinal mucus was significantly increased (P<0.01). The expression of Col-Ⅰ, FN, and α-SMA proteins and mRNAs in lung tissue was significantly upregulated (P<0.01). Compared with the model group, the groups of Wuwei Shenqintang exhibited significantly reduced inflammatory infiltration and blue collagen deposition in lung tissue, alleviated colonic damage, decreased expression of IL-6, IL-8, IL-1β, TNF-α, and SIgA in bronchoalveolar lavage fluid and intestinal mucus (P<0.01), and reduced average absorbance values and mRNA expression of Col-Ⅰ, FN, and α-SMA in lung tissue (P<0.05, P<0.01), with the prednisone group and the medium-dose and high-dose groups of Wuwei Shenqintang showing the most significant effects. The metabolomics results for lung tissue showed that compared with the blank group, the model group had 19 significantly different compounds (P<0.05, P<0.01). Wuwei Shenqintang could normalize 17 of these compounds compared with the model group (P<0.05, P<0.01). Fecal metabolomics results showed that compared with those in the blank group, there were 42 compounds with significant differences in the model group (P<0.05, P<0.01). Compared with the model control group, Wuwei Shenqintang could normalize 41 of these compounds (P<0.05, P<0.01). The combined analysis results indicated that Wuwei Shenqintang might inhibit pulmonary fibrosis by regulating the biosynthesis of phenylalanine, tyrosine, and tryptophan as well as the retinol metabolism pathway. ConclusionWuwei Shenqintang can ameliorate pulmonary fibrosis, which may be related to the regulation of the "lung-intestine axis".

Objective To investigate the relationship between Helicobacter pylori (Hp) infection and disease severity and pathological type of intestinal polyps in inpatients. Methods The data of 303 inpatients with intestinal polyps in the hospital from August 2022 to February 2025 were collected and analyzed. The clinical characteristics of patients were analyzed, and the influencing factors of pathological types of polyps were explored. Results Among the 303 inpatients with intestinal polyps, there were 135 Hp positive cases and 168 Hp negative cases. The number of polyps, maximum polyp diameter, number of ileocecus/ascending colon/transverse colon polyps, number of descending colon/sigmoid colon/rectal polyps and adenomatous polyps in the Hp-positive group were higher than those in the Hp-negative group (P<0.05). Multivariate logistic regression analysis indicated that age [OR (95%CI)=1.03 (1.01-1.05)] and positive Hp[OR (95%CI)=2.61 (1.62-4.20)] were independent risk factors of occurrence of adenomatous polyps (P<0.05). ROC curve results revealed that the AUCs of age, positive HP and combination in the diagnosis of adenomatous polyps were 0.574, 0.608 and 0.646, and the 95%CI values were 0.509-0.638, 0.545-0.672 and 0.584-0.708 respectively. The efficiency of combination of the two indexes was higher than that of single diagnosis. Conclusion Hp infection is associated with disease severity in inpatients with intestinal polyps, and it may be involved in the occurrence and development of adenomatous polyps.
