ABSTRACT
Objective:To investigate the effect of Clostridium butyricum on renal tissue of db/db mice and to explore its mechanism. Methods:Fourteen-week-old db/db mice were divided into db/db group( n=10) and db/db+ Cb group( n=7) according to random number table method. Age-matched db/m mice were selected as the normal control group. The db/m and db/db mice were administered 0.9% sodium chloride solution by gavage, while the db/db+ Cb mice were administered an equivalent amount of Clostridium butyricum solution by gavage for 8 weeks. Serum creatinine , fasting blood glucose, urinary albumin to creatinine ratio(ACR) and other biochemical indicators were also detected. HE staining was used to observe the pathological changes of kidney tissue. The expressions of peroxisome proliferators-activated receptor γ coactivator-1α(PGC-1α) mRNA were detected by realtime PCR, while the expressions of nuclear factor-κB(NF-κB), glucagon-like peptide 1 receptor(GLP-1R), and adenosine monophosphate-activated protein kinase(AMPK) in kidney tissue were determined by immunohistochemistry and Western blotting. The levels of intestinal flora, serum and fecal short-chain fatty acids(SCFAs) were measured by 16S rRNA, liquid chromatograph-mass spectrometer, and gas chromatograohy-mass spectrometry respectively. Results:Compared to db/db mice, db/db+ Cb mice showed improvement in general condition after supplementation with Clostridium butyricum. Fasting blood glucose, blood urea nitrogen, albumin-to-creatinine ratio(ACR), blood creatinine, and levels of interleukin-6(IL-6) in kidney tissue were reduced(all P<0.05). The pathology showed various degrees of amelioration of kidney tissue injury in mice. The expression of PGC-1α mRNA increased in kidney tissue( P<0.05). Decreased expression of NF-κB protein, as well as increased expression of GLP-1R and phosphorylated(p-)AMPK/AMPK protein(all P<0.05) were detected in kidney tissues. Clostridium butyricum modulated the composition of the gut microbiota with elevated total SCFAs in blood and feces. Conclusion:Clostridium butyricum increased the expression of GLP-1R in kidney tissue, promoted AMPK phosphorylation, and alleviated renal tissue damage in mice. This suggests that it may be associated with regulating the abundance of SCFA-producing bacterial populations.
ABSTRACT
Purpose: This study investigated the effects of oral administration of Clostridium butyricum (C. butyricum) on inflammation, oxidative stress, and gut flora in rats with hepatic ischemia reperfusion injury (HIRI). Methods: The rats from C. butyricum group were given C. butyricum for 5 days. Then, hepatic ischemia for 30 min and reperfusion for 6 h were performed in all the rats. After the animals were sacrificed, alanine transaminase (ALT), aspartate aminotransferase (AST), lipopolysaccharide (LPS) in serum, short-chain fatty acids (SCFAs), and gut microbiota composition in feces, and malondialdehyde (MDA), glutathione (GSH), tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6), Toll-like receptor 4 (TLR4), nuclear factor-kappa Bp65 (NF-κBp65) and histological analysis in the liver were performed. Results: The rats given C. butyricum showed decreased ALT, AST, LPS, and MDA; improved GSH and histological damage; changes in SCFAs; declined TNF-α, IL-6, TLR4, and pNF-κBp65/NF-κBp65; and changes in the gut microbial composition, which decreased the Firmicutes/Bacteroidetes ratio and increased the relative abundance (RA) of probiotics. Conclusions: C. butyricum supplementation protected against HIRI by regulating gut microbial composition, which contributed to the decreased LPS and attenuation of inflammation and oxidative stress. These indicate C. butyricum may be a potent clinical preoperative dietary supplement for HIRI.

Objective:To investigate the effects of Clostridium butyricum on colitis and intestinal microbiota in mice with or without antibiotic pretreatment. Methods:Thirty specific pathogen free BALB/c mice were randomly divided into the blank control group, dextran sulfate sodium (DSS) group, antibiotic + DSS group, Clostridium butyricum + DSS group and antibiotic+ Clostridium butyricum + DSS group, with 6 mice in each group. After the mice were pretreated with quadruple antibiotics (ampicillin 1 g/L, neomycin 1 g/L, metronidazole 1 g/L, and vancomycin 0.5 g/L) in normal drinking water for 30 d, the mice colitis model was induced with DSS. At the same time, the mice in Clostridium butyricum + DSS group and antibiotics+ Clostridium butyricum + DSS group were given 1×10 6colony-forming unit (CFU) Clostridium butyricum by gavage. The effect of Clostridium butyricum on mice with colitis was evaluated by disease activity index (DAI), colon length and histopathological score. The level of serum inflammatory factors was detected by enxyme linked immunosorbent assay, and the effect of Clostridium butyricum on gut microbita in mice was determined by fecal 16S rRNA sequencing. Results:The general condition of mice of the blank control group were good, and their DAI scores fluctuated around 0. Since the fourth day after DSS drinking water was given, the mice of the DSS group showed signs of colitis such as weight loss, unformed stools and bloody stools. On the fourth day after intervention, the DAI score of Clostridium butyricum + DSS group was lower than that of DSS group (0.000±0.000 vs. 0.444±0.111), and the difference was statistically significant ( t=4.000, P=0.016 1). On the tenth and twelfth day after the intervention, the DAI scores of antibiotic+ Clostridium butyricum + DSS group were both lower than those of antibiotic+ DSS group (0.000±0.000 vs. 1.111±0.222, 0.667±0.000 vs. 1.889±0.222), and the differences were statistically significant ( t=5.000 and 5.500, both P<0.05). The histopathological score of mice colon tissue of Clostridium butyricum + DSS group was lower than that of DSS group (2.50±1.73 vs. 5.50±1.00), and the histopathological score of mice colon tissue of antibiotic+ Clostridium butyricum+ DSS group was lower than that of antibiotic+ DSS group (1.25±0.96 vs. 5.00±0.82), and the differences were statistically significant ( t=3.000 and 5.960, both P<0.05). The serum level of interleukin (IL)-1β Clostridium butyricum+ DSS group was higher than that of blank control group ((4.464±0.075) ng/L vs. (3.907±0.080) ng/L), the serum levels of tumor necrosis factor-α, IL-6 and IL-1β of Clostridium butyricum+ DSS group and antibiotic+ Clostridium butyricum + DSS group were all lower than those of DSS group ((2.402±0.383) ng/L , (1.845±0.345) ng/L vs. (6.958±1.084) ng/L, (1.752±0.146) ng/L, (1.307±0.048) ng/L vs. (3.537±0.608) ng/L, (4.464±0.075) ng/L, (4.066±0.190) ng/L vs. (7.477±0.339) ng/L), and the differences were statistically significant ( t=5.005, 3.964, 4.495, 4.693, 6.294, 8.674 and 8.774 , all P<0.05). The results of 16S rRNA sequencing showed that there were a significantly large number of anti-inflammatory or short-chain fatty acid producing bacteria in the gut microbiota of mice intervened by Clostridium butyricum, among which the dominant bacteria genus in Clostridium butyricum + DSS group and antibiotic+ Colstridium butyicum+ DSS group were Mucispirillum (linear discriminant analysis (LDA)=3.667 log10, P=0.004) and Stenotrophomonas (LDA=2.778 log10, P=0.044). In the antibiotic+ Clostridium butyricum+ DSS group, the dominant bacteria genus were Peptococcus (LDA=2.685 log10, P=0.018), Butyricimonas (LDA=2.712 log10, P=0.011), Bilophila (LDA=3.204 log10, P=0.014), Intestinimonas (LDA=3.346 log10, P=0.010), Candidatus- Saccharimonas (LDA=3.363 log10, P=0.029), Desulfovibrio (LDA=3.402 log10, P=0.025), Oscillibacter (LDA=2.870 log10, P=0.019) and Akkermansia (LDA=4.031 log10, P=0.005). Conclusions:Clostridium butyricum can effectively improve colitis in mice and regulate the intestinal microbial structure of mice, whlie antibiotic pretreatment can strengthen its regulation of intestinal microbiota to and enhance the efficacy of Clostridium butyricum.

ABSTRACT
Objective To explore the effect of Clostridium butyricum ( C. butyricum ) and its metabolite butyrate on the function of intestinal mucosal barrier and intestinal flora in acute necrotizing pancreatitis ( ANP) rats with intra-abdominal hypertension ( IAH) . Methods Eighty SD rats were randomly divided into normal control group (A group, n=20), ANP with IAH group(B group, n=20), ANP with IAH and C. butyricum treated group ( C group, n=20 ) , ANP with IAH and sodium butyrate treated group ( D group, n=20). Rats of C and D group were given intragastric administration of C. butyricum 1 × 109 CFU once a day or 100 mg/kg sodium butyrate once a day from 10 days before modeling. Sodium taurocholate injection method via pancreatobiliary ducts was used to establish ANP with IAH rat model, and the intra-abdominal pressure was measured by direct puncture of left lower belly 24 h after modeling. Blood samples were collected for detecting serum amylase(AMY), tumor necrosis factor alpha (TNF-α), diamine oxidase( DAO ) , lipopolysaccharide ( LPS ) and D-Lactate, and the pathological changes of terminal ileum was observed. Real-time quantitative PCR was used to detect the populations of 6 bacteria in ileum mucosa. Results The levels of AMY, TNF-α, LPS,DAO, D-Lactate and ileum mucosa score were obviously higher in B, C and D group than those in A group, but the number of piobiotic flora in ileum mucosa was lower than that in A group, while the number of pathogenic bacteria was higher than that in A group. The levels of LPS, DAO, D-Lactate and ileum mucosa pathological score were lower in C group and D group than those in B group, but the number of piobiotic flora in ileum mucosa was lower than that in B group, while the number of pathogenic bacteria was higher than that in B group. All the differences above were statistically different (P<0.05). Conclusions C. butyricum and butyrate can maintain the function of intestinal mucosal barrier in ANP rats with IAH, and also readjust the imbalance of intestinal flora.

ABSTRACT
OBJECTIVE:To investigate the effects of clostridium butyricum combined with antibiotics on inflammatory factors and gastrointestinal function of patients with acute appendicitis after laparoscopic surgery. METHODS:A total of 102 patients with acute appendicitis undergoing laparoscopic surgery in our hospital during Jan. 2014-Jan. 2015 were divided into observation group and control group according to odd-even admission number,with 51 cases in each group. Control group was given Cefuroxime sodi-um for injection,Metronidazole injection and Cefixime dispersible tablets for anti-infective therapy after surgery. Observation group was additionally given Clostridium butyricum capsule 1260 mg,tid,for consecutive 3 d,on the basis of control group. The levels of serum inflammatory factors(TNF-α,IL-6),gastrin(GAS)and motilin(MTL)were compared between 2 groups before surgery and 3 d after surgery. The time of gastrointestinal function recovery(the time of bowel sounds,the time of first flatus,the time of postoperative first defecation)and the occurrence of compliance were recorded in 2 groups. RESULTS:Before surgery,there was no statistical significance in the levels of serum inflammatory and GAS,MTL factors between 2 groups (P>0.05). 3 d after sur-gery,the levels of TNF-α,IL-6 and CRP in 2 groups were decreased significantly,while the levels of GAS and MTL were in-creased significantly;above indexes of observation group were significantly better than those of control group,with statistical sig-nificance(P<0.05). The time of bowel sounds,the time of first flatus and the time of postoperative first defecation in observation group were significantly shorter than control group,with statistical significance(P<0.05). The incidence of complications in obser-vation group was 3.92％,which was significantly lower than 15.69％of control group(P<0.05). CONCLUSIONS:Clostridium bu-tyricum combined with antibiotics can effectively relieve inflammatory state of patients with acute appendicitis after laparoscopic sur-gery,promote gastrointestinal function recovery,and reduce the occurrence of complications.

ABSTRACT
Objective To explore the influence of Clostridium butyricum on the expression of vascular endothelial cell growth factor (VEGF) and its receptor 2 (VEGFR-2), proliferating cell nuclear antigen (PCNA), and tight junction protein claudin-2 in intestinal tissue in newborn rat with necrotizing enterocolitis (NEC). Methods Forty-eight-hour-old Sprague-Dewley (SD) rats were randomly divided into model group, control group, low-dose group, mid-dose group, and high-dose group, 12 rats each. Rats in each group were fed with milk substitute. The NEC model were created by hypoxia and cold stimulation for 3 consecutive days in model group, low-dose group, mid-dose group, and high-dose group. Meanwhile, low-dose group, mid-dose group, and high-dose group were intervened by being fed with Clostridium butyricum 0.2, 0.4, and 0.8 g/(kg·d), respectively. All rats in each group were sacriifced on day 4 and the intestines tissue was obtained. The pathological changes had been observed. The expression of VEGF, PCNA, and claudin-2 were detected by immunohistochemistry. The expression of VEGFR-2 was detected by RT-PCR. Results The intestines pathological scores was signiifcantly different among ifve groups (P?0 . 05 ). Conclusion The expression of VEGF, VEGF-2 , and claudin-2 were higher in rats with NEC, while the expression of PCNA was lower. Supplementation of Clostridium butyricum may protect newborn rats by its act on these factors.
ABSTRACT
Background The production of biofuels from renewable energy sources is one of the most important issues in biotechnology today. The process is known to generate various by-products, for example glycerol that is obtained in the making of biodiesel from rapeseed oil. Crude glycerol may be utilized in many ways, including microbial conversion to 1,3-propanediol. The main drawback of that technology is the use of high concentrations of glycerol, which inhibits the growth of bacterial cells. Results This study investigated the impact of crude glycerol on Clostridium butyricum DSP1 and its ability to adapt to an environment of high osmotic pressure. It was found that a crude glycerol concentration of up to 70 g/L did not have an inhibitory effect on C. butyricum DSP1. Adaptation procedures involving the passage of metabolically active biomass from a fermentation medium with a lower concentration of crude glycerol to one with a greater substrate concentration allowed breaking the barrier of high osmotic pressure (150 g/L crude glycerol) and receiving a 1,3-PD concentration of 74 g/L in a batch culture operation. The work looked into intracellular modifications shown by proteomic profiling in order to explain the mechanisms underlying the response and adaptation of bacterial cells exposed to unfavorable environmental conditions. Conclusions This study of the effect of glycerol on the growth and metabolism of C. butyricum DSP1 demonstrated that the maximum substrate concentrations that do not inhibit the metabolic activity of bacterial cells are 90 g/L and 70 g/L for pure and crude glycerol, respectively.

[ ABSTRACT] AIM:To investigate the preventive effects of Clostridium butyricum ( C.butyricum) on the type of pylorus ligated gastric ulcer ( GU) in mice and the underlying mechanisms.METHODS:ICR mice were randomly divided into 4 groups:sham operation group, model group, C.butyricum pretreatment group and omeprazole pretreatment group. Gastric pyloric ligation was adopted to establish GU model in mice.The gastric juice was collected to measure the content of gastric free mucus, the pH of gastric juice and the activity of pepsin.The gastric tissues were collected for routine HE stai-ning to observe the pathological changes.The content of glycogen was detected by PAS staining.The protein expression of Bax and Bcl-2 in the gastric mucosa was also assessed by immunohistochemical staining.RESULTS: The HE and PAS staining showed that the C.butyricum pretreatment obviously attenuated the mucosa lesion induced by ligation.Compared with model group, the pH of gastric juice was significantly raised.The activity of pepsin fell off in C.butyricum group, which was lower than that in omeprazole group.In comparison with model group, the content of gastric free mucus was dra-matically increased and PAS staining showed a significant rise in C.butyricum group, but not in omeprazole group.The protein expression of Bax was decreased and the protein expression of Bcl-2 was upgraded in C.butyricum group than those in model group.CONCLUSION:C.butyricum protects gastric mucosa against the challenge of pylorus ligation in mice and its mechanism may be related to inhibiting gastric acid secretion and the activation of pepsin, increasing the production of gastric free mucus, strengthening the expression of bcl-2 gene and inhibiting the expression of bax gene.
ABSTRACT
@#An agar diffusion method was used to investigate the antimicrobial activities of fermentation broth of Lactobacillus acidophilus(L. acidophilus), and Clostridium butyricum(C. butyricum)against Shigella flexneri(S. flexneri)infection in vitro. It was found that cell-free culture supernatants(CFCSs)of L. acidophilus and C. butyricum possessed remarkable synergistic anti-S. flexneri activity in vitro and the antimicrobial activity of the mixed culture was 17. 2% and 22. 4% greater, than single strains alone, respectively. Meanwhile, there was a symbiotic relationship between L. acidophilus and C. butyricum. The result showed that the biomass accumulation of the mixed culture reached 4. 27 g/L(DCW)and increased by 6. 0% and 30. 6% compared to the L. acidophilus and C. butyricum, respectively. Moreover, L. acidophilus and C. butyricum clearly inhibited S. flexneri adhesion to Caco-2 cells by 75. 8% and 81. 2%, and the combination of these two probiotic strains demonstrated the highest inhibition rate, reaching 84. 2%, while the viability of Caco-2 cells treated with L. acidophilus, C. butyricum or their combination was increased by 11. 5%, 12. 5% and 22. 9%, respectively. The synergistic effect of L. acidophilus and C. butyricum provided better protection against Shigella flexneri infection, which represents a promising alternative therapy for shigellosis.
ABSTRACT
Five acid forming bacteria, SK3-3, SK3-6B, SK3-7B, SK13-3 and PL20-4S were isolated from soils collected in Samut Songkhram and Phitsanulok provinces. All isolates were Gram-positive, anaerobic, spore-forming, rodshaped bacteria. The isolates were screened for their end product fermentation and were identified based on their phenotypic characteristics and 16S rRNA gene sequence analyses. They were belonged to the genus Clostridium and were closely related to Clostridium butyricum DSM 10702T (99.7-100%) and Clostridium saccharoperbutylacetonicum N1-4T (98.0-98.2%) based on 16S rRNA gene sequence similarity. All 5 isolates were identified as Clostridium butyricum. They produced 4.51-8.90 g/L (19.40-54.82% yield) of L-lactic acid with 0.06-0.12 g/L/h productivity, 6.15-7.52 g/L of acetic acid and 24.32-29.67 g/L of ethanol as the end product fermentation.
