ObjectiveTo investigate the potential mechanisms of Zingiberis Rhizoma in treating inflammatory bowel disease （IBD） by integrating network pharmacology with in vitro and in vivo experiments. MethodsTraditional Chinese Medicine Systems Pharmacology Database And Analysis Platform （TCMSP）， Traditional Chinese Medicine Integrated Database （TCMID） Database were used to obtain the active component targets of Zingiberis Rhizoma. GeneCards was used to obtain the IBD targets. DAVID was used to perform Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses on core targets. Cytoscape 3.10.2 was used to establish the "active component-disease target-signaling pathway" interaction network. Mice were randomly assigned to control， model， and Zingiberis Rhizoma （400 mg·kg^-1） groups. An IBD model was induced via dextran sulfate sodium （DSS）. The colonic tissue was collected post-treatment to assess histology， expression of Ly6C⁺ monocytes/macrophages， and mRNA levels of Toll-like receptor 4 （TLR4）， and inflammatory cytokines. The effect of Zingiberis Rhizoma aqueous extract on RAW264.7 cell viability was evaluated. Furthermore， the effects of the extract at 100， 10， and 1 mg·L^-1 on LPS-induced differentiation of RAW264.7 cells into Ly6C^hi monocytes/macrophages， mRNA levels of TLR4 and inflammatory cytokines， and protein levels of factors in the TLR4/mitogen-activated protein kinase （MAPK） signaling pathway. ResultsA total of 241 targets were identified for Zingiberis Rhizoma and 6 787 for IBD， with 122 shared targets among Zingiberis Rhizoma， ulcerative colitis （UC）， and Crohn's disease （CD）. The enrichment analyses yielded 297 GO terms and 88 KEGG pathways. Associations were noted between Zingiberis Rhizoma's active component targets and IBD targets. In vivo experiments： Compared with the control group， the model group showed decreased body weight and disease activity index （DAI）（P<0.01）， shortened colon length， damaged mucosal epithelium with inflammatory cell infiltration， raised pathological scores （P<0.05）， increased Ly6C^hi and Ly6C^lo monocytes/macrophages （P<0.05）， and up-regulated mRNA levels of TLR4， TNF-α， IL-1β， and IL-6 （P<0.05） and protein levels of TLR4， phosphorylated extracellular signal-regulated protein kinase 1/2 （p-ERK1/2）， and phosphorylated p38 MAPK （p-p38 MAPK） （P<0.05）. Zingiberis Rhizoma intervention reversed these changes and reduced Ly6C^hi monocytes/macrophages （P<0.01）. In vitro experiments： compared with the control， LPS increased the proportion and number of Ly6C^hi monocytes/macrophages and mRNA levels of TLR4， TNF-α， IL-1β， and IL-6 （P<0.01） and enhanced the expression of TLR4， p-ERK1/2， and p-p38 MAPK （P<0.05）. Zingiberis Rhizoma reduced Ly6C^hi monocytes/macrophages （P<0.05）， down-regulated the mRNA levels of inflammatory cytokines （P<0.05）， and suppressed the TLR4/MAPK pathway （P<0.05）. ConclusionZingiberis Rhizoma alleviates IBD by suppressing the TLR4/ERK/p38 MAPK signaling pathway and reducing inflammatory cytokine levels in Ly6C^hi monocytes/macrophages.

ObjectiveTo clarify the repair effect of Mume Fructus on the intestinal mucosal epithelial barrier in the mouse model of inflammatory bowel disease （IBD） and explore the repair mechanism. MethodsThirty-six male C57BL/6 mice were randomly assigned into six groups： normal， model， low-， medium-， and high-dose （200， 400， and 800 mg·kg^-1） Mume Fructus， and sulfasalazine （300 mg·kg^-1）. Except the normal group， the rest groups had free access to 2% dextran sulfate sodium （DSS） solution for seven days to establish the IBD model， followed by a seven-day drug intervention. The body weight change and disease activity index （DAI） were recorded. After the last administration， spleen and colon tissue samples were collected to analyze the differences in colon length and spleen index. Hematoxylin-eosin staining was used to observe the morphology of the colon tissue. The level of diamine oxidase （DAO） in the serum was measured by the DAO assay kit. Immunohistochemistry was employed to determine the expression of tight junction proteins such as Claudin-1， Occludin， and zonula occludens-1 （ZO-1） in the colon tissue. Real-time PCR was performed to measure the mRNA levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in the colon tissue. Finally， Western blot was employed to determine the protein levels of mitogen-activated protein kinase kinase （MEK）， extracellular signal-regulated kinase （ERK）， phosphorylated （p）-MEK， and phosphorylated ERK in the colon tissue. ResultsCompared with the normal group， the model group exhibited decreases in body weight and colon length （P<0.01）， increases in DAI， spleen index， and serum DAO level （P<0.01）， damaged colonic epithelium and goblet cells， and obvious infiltration of inflammatory cells. In addition， the model group exhibited higher positive expression of Claudin-1， Occludin， and ZO-1 （P<0.01）， higher mRNA levels of TNF-α and IL-1β （P<0.01）， and higher protein levels of p-MEK and p-ERK （P<0.05， P<0.01） than the normal group. However， sulfasalazine and three doses of Mume Fructus markedly decreased the body weight and DAI （P<0.05）， recovered the colon length and spleen index， alleviated colon tissue damage， lowered the level of DAO in the serum （P<0.01）， and down-regulated the mRNA levels of TNF-α and IL-1β （P<0.01） and the protein levels of p-MEK and p-ERK （P<0.05）. Sulfasalazine and low- and medium-dose Mume Fructus increased the positive expression of Occludin， Claudin-1， and ZO-1 （P<0.05， P<0.01）. Furthermore， high-dose Mume Fructus elevated the protein expression of Occludin （P<0.05）. ConclusionMume Fructus can restore the expression of intestinal epithelial tight junction proteins by inhibiting the phosphorylation of proteins in the MEK/ERK signaling pathway and down-regulating the levels of TNF-α and IL-1β， thus repairing the intestinal mucosal barrier in the mouse model of IBD.

ObjectiveTo investigate the modulating effect of modified Wumeiwan （MWMW） on the ulcerative colitis （UC）-associated intestinal helper T cell 17 （Th17）/regulatory T cell （Treg） balance and intestinal flora by using a human flora-associated model of UC patients with dampness-heat obstruction syndrome， thus providing a new idea for the UC-related research and therapeutic strategies. MethodsThe 24 male C57BL/6J mice were randomized into normal control， model， and MWMW groups （n=8）. Model and MWMW groups were first treated with an antibiotic cocktail （vancomycin， 0.1 g·kg^-1； neomycin sulfate， 0.2 g·kg^-1； ampicillin， 0.2 g·kg^-1； metronidazole， 0.2 g·kg^-1） for 21 days. At the end of antibiotic treatment， the gavage of fecal microbiota suspension from UC patients with dampness-heat obstruction syndrome was started at a dose of 0.2 mL·d^-1 for 19 consecutive days， by which a human flora-associated model of UC was obtained. The MWMW group was administrated daily with MWMW liquid （12.5 g·kg^-1）， while the normal control and model groups were administrated by gavage with an equal amount of sterile water for 7 consecutive days. The symptoms of dampness-heat obstruction were observed. The colon length and spleen index were measured and calculated， and the proportions of Th17 and Treg cells were detected by flow assay. The intestinal flora was analyzed by 16S rRNA high-throughput sequencing. ResultsCompared with the normal control group， the model group showed shortened colon （P<0.05） and increased spleen index （P<0.01）. Compared with the model group， the MWMW group showed prolonged colon （P<0.01） and decreased spleen index （P<0.05）. After the intervention of MWMW， the Th17 proportion and Th17/Treg ratio in the colon decreased （P<0.01）， and the proportion of Treg cells increased （P<0.05）. The number of species and alpha and beta diversity of intestinal flora in mice were regulated by MWMW （P<0.05）. In terms of intestinal flora composition， MWMW increased the relative abundance of several phyla （Firmicutes， Proteobacteria， Fusobacteriota， Actinobacteriota， and Gemmatimonadota）， the genus Bacteroides， and two species （Bacteroides thetaiotaomicron and B. fragilis） in model mice. Moreover， Spearman's correlation analysis showed that the relative abundance of B. thetaiotaomicron and B. fragilis were negatively correlated with the Th17 level （P<0.05）. In addition， the above changes in intestinal flora caused the changes in microbial genes involved in 14 pathways， such as glycolysis， amino acid degradation， inorganic nutrient metabolism， biosynthesis of pyrimidine deoxyribonucleotides， antibiotic resistance， and degradation of polysaccharides. ConclusionsThe human flora-associated model successfully simulated the changes （marked by a decrease in the abundance of Bacteroides） of intestinal flora in UC patients with dampness-heat obstruction syndrome. MWMW can enrich the abundance of beneficial bacteria such as B. thetaiotaomicron and B. fragilis and promote the synergistic intestinal immune modulation with the metabolic functions centered on glycolysis， amino acid metabolism， and nucleotide synthesis through bacterial polysaccharide utilization sites to reduce the Th17/Treg ratio， thereby exerting a protective effect on UC.

ObjectiveTo investigate the effect and mechanism of Sishenwan in restoring the intestinal barrier function in the rat model of diarrhea-predominant irritable bowel syndrome （IBS-D） due to spleen-kidney Yang deficiency based on intestinal flora and short-chain fatty acids. MethodsAfter the delivery of 10 SPF-grade pregnant rats， 4 male suckling rats were kept in each litter for the experiment. The male suckling rats were randomly allocated into blank， model， low-dose （3.51 g·kg^-1） Sishenwan， high-dose （7.02 g·kg^-1） Sishenwan， and Peifeikang （0.54 g·kg^-1） groups， with 8 rats in each group. The blank group was fed conventionally， and the other groups were subjected to mother-child separation and Sennae Folium gavage （1 g·mL^-1， 10 mL·kg^-1） for the modeling of IBS-D due to spleen-kidney Yang deficiency. After the modeling was completed， the rats in Sishenwan groups were administrated with the corresponding dose of Sishenwan decoction by gavage， and the Peifeikang group with bifidobacterium triple live powder+normal saline suspension. The blank and model groups were treated with an equal volume of normal saline by gavage. The general conditions and fecal characteristics of rats were observed. After 2 weeks of administration， the rats were anesthetized for sample collection. The pathological changes of the colon tissue in rats were observed by hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was employed to measure the levels of transforming growth factor-beta （TGF-β）， interleukin-10 （IL-10）， and interleukin-22 （IL-22）. Immumohistochemical staining （IHC） was performed to detect the positive expression of zonula occludens-1 （ZO-1） and occludin in the colon tissue. Western blot was employed to determine the protein levels of ZO-1 and occludin in the colon tissue of rats， and 16S rRNA gene sequencing was performed for intestinal flora. Gas chromatography-mass spectrometry was employed to determine the content of short-chain fatty acids （SCFAs） in the cecum contents of rats. ResultsThe colon tissue in the blank group presented a clear structure， neat glands， and no inflammatory cell infiltration. In the model group， the colon tissue showcased a disorganized structure， irregular arrangement of glands， and inflammatory cell infiltration. Compared with the model group， the low-dose and high-dose Sishenwan groups and the Peifeikang group exhibited an intact colon tissue structure， regular arrangement of glands， and reduced inflammatory cell infiltration. Compared with the blank group， the modeling lowered the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.01）， down-regulated the protein levels of ZO-1 and occludin in the colon tissue （P<0.01）， and decreased the content of acetic acid and propionic acid and increased the content of butyric acid in cecum contents （P<0.05）. Compared with the model group， low-dose and high-dose Sishenwan raised the levels of TGF-β， IL-10， and IL-22 in the serum （P<0.05， P<0.01）， and Peifeikang elevated the levels of TGF-β and IL-10 in the serum （P<0.01）. High-dose Sishenwan and Peifeikang up-regulated the protein levels of ZO-1 and occludin （P<0.05， P<0.01）， increased the content of acetic acid and propionic acid in cecum contents （P<0.05）， and decreased the content of butyric acid （P<0.05）. The 16S rRNA gene sequencing results showed that the intestinal flora structure of the model group changed compared with that of the blank group. Compared with the model group， Sishenwan and Peifeikang increased the relative abundance of Lachnospiraceae， Muribaculaceae， Akkermansiaceae， Ligilactobacillus， UBA3282， Akkermansia， and Corynebacterium while reducing the relative abundance of Oscillospiraceae， Desulfovibrionaceae， Lactobacillus， Romboutsia， and Desulfovibrio. They can restore the intestinal flora structure similar to that in the blank group. ConclusionSishenwan can alleviate diarrhea symptoms and colonic mucosal inflammation， increase the expression of tight junction proteins in the colonic mucosa， and strengthen the intestinal barrier in IBS-D rats with the syndrome of spleen-kidney Yang deficiency. The mechanism of action may be related to optimizing the structure and balance of intestinal flora and regulating the SCFAs， and the effect of high-dose Sishenwan is obvious.

Objective To investigate the changes of serum metabolites in patients with occupational chronic lead poisoning using non-targeted metabolomics, and to screen differential metabolic pathways. Methods A total of 14 patients with occupational chronic lead poisoning were selected as the poisoning group, and 14 healthy people without occupational hazard exposure history were selected as the control group using the judgment sampling method. Serum of the individuals from the two groups was collected. Non-targeted metabolomics technology based on ultra high performance liquid chromatography-tandem mass spectrometry was used to detect serum metabolite levels in the two groups. Differential metabolites (DMs) were screened by the principal component analysis, partial least squares discriminant analysis and orthogonal partial least squares discriminant analysis, and related metabolic pathways were explored. Results The blood lead level in the poisoning group was higher than that in the control group (median: 359.59 vs 5.04 μg/L, P<0.01). There were significant differences in serum metabolites between the poisoning group and control group. After the combination of results from the positive and negative ion patterns, a total of 89 DMs were screened in serum of patients in the poisoning group, including 50 upregulated and 39 downregulated metabolites compared with the control group. The serum DMs of poisoning group were mainly enriched in arginine biosynthesis, ABC transporter, purine metabolism, choline metabolism in malignant tumor, glycerophospholipid metabolism and ether lipid metabolism compared with the control group (all P<0.05). Conclusion Abnormal changes of serum metabolic profile occurred in patients with occupational chronic lead poisoning. The metabolic pathways such as arginine biosynthesis, ABC transporter, purine metabolism, choline metabolism, glycerophospholipid metabolism and ether lipid metabolism may be involved in the occurrence and development of lead poisoning.
