ObjectiveTo study the role of Kukoamine B (KB) in inhibiting the inflammatory response of small intestine in septic mice and its molecular mechanisms.Methods Twenty-four male ICR mice were randomly divided into control group, model group, and KB intervention group (each,n= 8). Sepsis model was reproduced by intra-peritoneal injection of 20 mg/kg lipopolysaccharide (LPS), while equivalent normal saline was given in control group, and 20μg/kg KB was injected through caudal vein 4 hours after LPS challenge in KB intervention group. The blood/tissue samples (jejunum and ileum) were harvested 8 hours after LPS injection. The levels of plasma LPS, tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were measured. The pathological changes in small intestine tissues were observed under light microscope, while the levels of inflammatory cytokines TNF-α and IL-1β in the tissue homogenates (jejunum and ileum) were assessed by enzyme linked immunosorbent assay (ELISA). The activity of myeloperoxidase (MPO) was measured by colorimetry. The expression of intercellular adhesion molecule-1 (ICAM-1) was determined by immunohistochemistry. The expressions of inducible nitric oxide synthase (iNOS) mRNA was assayed by reverse transcription-polymerase chain reaction (RT-PCR). The activation of nuclear factor-κΒ (NF-κΒ) was determined by Western Blot.Results The mice in model group were found to have an increase in microvascular permeability, interstitial edema, and infiltration of white blood cells, and the levels of LPS, TNF-α and IL-1β in their plasma, with an increase in concentrations of TNF-α and IL-1β, activity of MPO, positive expression of ICAM-1, expression of iNOS mRNA and NF-κB protein in small intestine (jejunum and ileum). Compared with model group, in mice with KB intervention, microvascular permeability, interstitial edema, and infiltration of white blood cells were reduced significantly, while the levels of LPS, TNF-α and IL-1β in plasma, the concentration of TNF-α and IL-1β, the activity of MPO, the positive expression of ICAM-1, the expression of iNOS mRNA and NF-κB protein in small intestine (jejunum and ileum) were significantly decreased [plasma LPS (kEU/L): 654.09±28.13 vs. 1 155.65±47.15, TNF-α (ng/L): 12.75±0.47 vs. 30.61±0.71, IL-1β (ng/L): 53.06±5.32 vs. 64.47±2.61; jejunum TNF-α(ng/L): 43.27±1.20 vs. 64.82±2.09, IL-1β (ng/L): 326.38±14.47 vs. 535.22±13.48, MPO (U/g): 0.14±0.01 vs. 0.32±0.02, iNOS mRNA (2-ΔΔCt): 2.39±0.13 vs. 10.80±0.22, NF-κB protein (gray value): 0.687±0.062 vs. 1.404±0.046; ileum TNF-α (ng/L): 62.75±3.92 vs. 104.24±2.82, IL-1β(ng/L): 408.06±1.70 vs. 521.97±1.16, MPO (U/g): 0.36±0.08 vs. 0.66±0.05, iNOS mRNA (2-ΔΔCt): 1.65±0.11 vs. 3.59±0.29, NF-κB protein (gray value):0.830±0.114 vs. 1.609±0.051, allP< 0.05].Conclusion KB can combine with LPS and inhibit LPS/Toll-like receptor 4 (TLR4) signaling pathway, thereby significantly inhibit the inflammatory response and protect the function of the small intestine in LPS-induced septic mice.

Objective To explore the changes in expression of Klotho, an aging-suppression protein, and neutrophil gelatinase associated lipocalin ( NGAL) and their relationship with rat mesangial cells ( RMCs) cultured with high glucose in vitro, and to explore the role played by Toll-like receptor-4 (TLR4) / nuclear factor-kB(NF-kB) p65 pathways in this process. Methods Three NGAL-siRNA sequences were designed and synthesized. The effective sequence in subsequent experiments was chosen. RMCs were preincubated with pyrrolidinedithiocarbamate (PDTC)or exogenously added Klotho prior to high glucose treatment. Realtime PCR was used to analyze Klotho, TLR4, NGAL mRNA expressions. Western blot was used to observe Klotho, TLR4,NF-kB p65, NGAL,fibronectin (FN), and connective tissue growth factor ( CTGF) protein expression. ELISA assay was used to detect monocyte chemoattractant protein-1 ( MCP-1) and CXCL5 secretions. Results High glucose suppressed Klotho expression significantly(P<0. 05) and activated TLR4 / NF-kB p65 pathway. Meanwhile,the levels of NGAL,FN,CTGF, MCP-1, and CXCL5 were highly expressed ( P < 0. 01). NGAL gene silencing obviously down-regulated the increased expressions of FN, CTGF, MCP-1, and CXCL5 ( P < 0. 01). After PDTC treatment the overexpression of NGAL protein was markedly lowered(P<0. 01). In addition, Klotho treatment significantly inhibited the activity of TLR4 /NF-kB p65 pathways and down-regulated the expressions of NGAL, FN, CTGF, MCP-1 and CXCL5 stimulated by high glucose(P<0. 01). Conclusion Klotho inhibits the activity of TLR4 / NF-kB p65 pathways and thus inhibits NGAL expression in RMCs cultured with high glucose in vitro. And then it suppresses the expressions of FN, CTGF, MCP-1, and CXCL5. This provides a new basis to illustrate the protection mechanism of the anti-aging protein Klotho in diabetic nephropathy, and may provide new ideas and therapeutic targets for prevention and treatment.
