RESUMO

The root of Codonopis bulleynana Forest ex Diels (cbFeD), a tonic food widely used in Yunnan Province of China, was found to have a wide range of pharmacological effects. The present study was designed to investigate the anti-fibrotic effect of water extracts of cbFeD in chronic liver injury mice model induced by carbon tetrachloride (CCl4) and to explore its underlying mechanisms. Phytochemical analysis revealed multiple components were present in the water extract of cbFeD and the compounds were mostly enriched in organic acid and its derivatives, flavone, amino acid derivatives, nucleotide and its derivatives, carbohydrates etc. Treatment with cbFeD significantly attenuated liver injury and fibrosis in CCl4-administered mice evidenced by improved liver histology, ameliorated apoptosis of hepatocytes, and decreased transaminase levels in the serum. Decreased activities of superoxide dismutase (SOD) and catalase (CAT) were markedly reversed upon treatment with cbFeD while levels of malondialdehyde (MDA) and glutathione (GSH) were significantly restored towards normal values. cbFeD also suppressed intrahepatic inflammatory cell infiltration and Kupffer cell activation. Furthermore, our study revealed an inhibitory effect of cbFeD on hepatic stellate cells (HSCs) activation both in vitro and in vivo. In conclusion, cbFeD could exert a protective role against liver fibrosis in mice model induced by CCl4 that is comparable to the positive control silymarin and might be developed into a promising anti-fibrotic drug.

RESUMO

OBJECTIVES: This study aimed to explore the effects of Psidium guajava L. extracts on mice diarrhea model and changes in their intestinal microflora diversity. METHODS: Mice diarrhea model was constructed with Folium Sennae. and The therapeutic effects of Psidium guajava L. extracts on diarrhea were evaluated by loose stools rates, diarrhea rates, diarrhea index and motor functions of intestine. RESULTS: Our results showed that all three kinds of extracts from Psidium guajava L. had inhibitory effects on Folium Sennae -induced diarrhea model. The proportion of Bacteroidetes is lower in Group DF (diarrhea model group) compared with Group B (blank group), while abundance of Deferribacteraceae was found in Group DF. The proportion of Deferribacteraceae lowered in Group DTF (diarrhea treatment group) treated with extracts from Psidium guajava L. CONCLUSIONS: However, mechanisms underlying the therapeutic effect of Psidium guajava L. and the changes in intestinal microflora still await further exploration.

RESUMO

As a complicated micro-ecosystem, gut microbes are closely related to metabolic disease, immune disease and tumor (such as constipation. Long-term constipation would cause intestinal mucosal injury, enteritis, ileus, etc., thus inducing intestine cancer). In this research, intestine cancer model group and Codonopsis foetens treatment group were successfully constructed, and the variation of intestinal microbes were analyzed by 16S rRNA sequence. Results showed that there were changes in bacteria abundance of Firmicutes, Bacteroidetes, Proteobacteria, Deferribacteres, Tenericutes, and Actinobacteria, etc. Codonopsis foetens could directly or indirectly affect the growth and metabolism of Deferribacteres by altering the nutritional ingredient and pH value of intestine "medium", thus affecting the occurrence and development of intestinal microbes.

RESUMO

To verify the laxative effect of Codonopsis bulleyana and its effect on intestinal microbiota, a long-term constipation model was established using 3.0 mg/kg loperamide hydrochloride, after which, the long-term constipation model was administered by 0.2 g/ml high-dose Codonopsis bulleyana water extract. The therapeutic effects were observed by measuring defecation amount and feces moisture content. The composition of intestinal microbiota was detected and analyzed using16S rDNA sequencing technology. The results showed that Codonopsis bulleyana water extract can increase stool quantity and promote intestinal tract movement in constipated mice. Obvious changes were shown in intestinal microbiota of chronically constipated mice treated with Codonopsis bulleyana water extract as the proportion of beneficial bacteria increased in the model treated by Codonopsis bulleyana. Codonopsis bulleyana water extract alleviates constipation symptoms caused by loperamide hydrochloride and improves the intestinal microbiota in constipated mice.

RESUMO

Intestinal cancer is a disease with high morbidity and high mortality in China. Previous studies have shown that Codonopsis foetens can inhibit cellular autophagy and promote the apoptosis of intestine cancer cells. Based on metabolomics method coupled with liquid chromatography-mass spectrometry (LC-MS) technology, we aimed to analyze intestinal small molecule metabolites in the intestinal cancer model group and the Codonopsis foetens treated group. Principal component analysis (PCA) and Partial Least Squares (PLS-DA) were used to identify the pattern of the data. And the metabolic characteristics of the cancer model group were explored based on the metabolic differences between the groups. Multivariate statistical analysis revealed that metabolites presented with differences included: Acetamide, Phosphoric acid, Hydrogen sulfite, Pyruvic acid, Cytosine, 2-Hydroxypyridine, Phosphoric acid, Uracil, Gamma-Aminobutyric acid, Glycerol alpha-monochlorohydrin, Thiosulfic acid, L-Valine, Cysteamine, Taurine, Creatine, Homocysteine, Hypoxanthine, Se-Methylselenocysteine, 5-Hydroxymethyluracil, Oxoglutaric acid, LysoPC(20:0), LysoPC(22:4(7Z,10Z,13Z,16Z)), LysoPC(18:2(9Z,12Z)), LysoPC(16:1(9Z)), LysoPE(0:0/16:0), LysoPE(0:0/18:2(9Z,12Z)), LysoPE(18:0/0:0), LysoPE(20:1(11Z)/0:0), etc. Combined with metabolic pathway analysis, pathways presented with differences included: Citrate cycle (TCA cycle), ABC transporters, 2-Oxocarboxylic acid metabolism, Taurine and hypotaurine metabolism, Butanoate metabolism), Phenylalanine, tyrosine and tryptophan biosynthesis, Biosynthesis of amino acids, Protein digestion and absorption, Aminoacyl-tRNA biosynthesis, C5-Branched dibasic acid metabolism, GABAergic synapse, Proximal tubule bicarbonate reclamation, Mineral absorption, Phenylalanine metabolism. The results showed that the proliferation of intestinal cancer cells caused cell metabolism disorders, manifesting as changes in metabolic pathways and resulting in changes in metabolites.

RESUMO

Despite its favorable clinical efficacy, oxaliplatin­based chemotherapy frequently results in treatment withdrawal and induces liver damage in colon cancer. Therefore, it is important to develop novel drugs, which can safely and effectively complement or replace the therapeutic effects of oxaliplatin. Codonopis bulleynana Forest ex Diels (cbFeD) has wide range of pharmacological effects, including anticancer effects. In the present study, the anticancer activity of cbFeD and its potential molecular mechanisms were investigated. In vitro, cell counting kit­8 assays and flow cytometry were used to assess the anti­proliferation and apoptosis­promoting activities of cbFeD. Transmission electron microscopy was used to monitor the autophagic vesicles. Immunofluorescence staining was performed to observe the nuclear translocation of p65 and the fluorescence of microtubule­associated protein 1 light chain 3 (LC3) B­II. The protein expression levels of p65, inhibitor of nuclear factor (NF)­κB (IκB) a, LC3B­I, LC3B­II and Beclin­1 were detected using western blot analysis. In vivo, the antitumor effect of cbFeD was assessed in colon cancer­bearing nude mice as a model. H&E staining and immunohistochemistry (IHC) were performed, with oxaliplatin set as a positive control. The results showed that cbFeD inhibited cell proliferation and promoted cell apoptosis in a dose­dependent manner. The effects of a high dose of cbFeD on colon cancer cells were similar to those of oxaliplatin. In HCT116 and SW480 cells, cbFeD inhibited the expression of IκBα, LC3B­I/II and Beclin­1, and the results of western blot analysis and immunofluorescence showed that, in the cells treated with cbFeD, p65 gradually entered nuclei in a dose­dependent manner, and the expression of LC3B­II was gradually reduced. The results of the acridine orangestaining and electron microscopy demonstrated fewer autophagic vesicles in the high­dose cbFeD group and the oxaliplatin group. The high dose of cbFeD reversed the effect of pyrrolidine dithiocarbamate, a p65­inhibitor, on the expression of p65, LC3B­I, LC3B­II and Beclin­1, and on the production of autophagic vacuoles. The high dose of cbFeD and oxaliplatin also suppressed tumorigenicity in vivo. The results of the H&E and IHC staining confirmed the inhibition of autophagy (LC3 and Beclin­1) and activation of p65 by treatment with the high dose of cbFeD and oxaliplatin. Taken together, cbFeD exhibited an antitumor effect in colon cancer cells by inhibiting autophagy through activation of the NF­κB pathway. Therefore, cbFeD may be a promising Chinese herbal compound for development for use in cancer therapy.

RESUMO

The roots of Codonopsis cordifolioidea (classified as campanulaceae cordifolioidea), locally known as Tsoong, have been used as a tonic food. The major components isolated from Tsoong have been demonstrated to present anti­human immunodeficiency virus­1 activities and cytotoxicity against various tumor cell lines. However, the possible effects of the novel compound isolated from Tsoong, cordifoliketones A, on pancreatic ductal adenocarcinoma (PDAC) cells, are still unknown. In the present study, cordifoliketones A extractions were prepared from Tsoong, and the possible effects on PDAC cell growth, apoptosis, migration and invasion in vitro and in vivo were exlored. The cytotoxicity assay, apoptosis assay, western blotting, migration and invasion assay, and a PDAC cell (AsPC­1, BxPC­3 and PANC­1) xenograft mice model were employed. The results demonstrated that treatment with cordifoliketones A: i) inhibited proliferation and promoted apoptosis of PDAC cells; ii) significantly induced apoptosis and altered expression of apoptosis­associated proteins in a dose­dependent manner; iii) suppressed migration and invasion of PDAC cells in a dose­dependent manner; and iv) restrained the growth of PDAC neoplasm in nude mice. Furthermore, cordifoliketones A demonstrated non­cytotoxic activity in a panel of normal human cells, including hTERT­HPNE, 293, hepatocyte HL­7702 and HL­1 cells. Therefore, these data indicated that cordifoliketones A may be a potential candidate compound for the prevention of PDAC cell proliferation and metastasis, presumably by induction apoptosis and inhibiting viability, invasion and migration of PDAC cells.
