To investigate the effects of negative therapy at back meridian points on blood gas components and immune functions in male college students, this study was conducted on treatment types(abdomen group and back group) at three sampling times (before, post-2 wks and post-4 wks) by using $2{\times}3$ factoral design. Blood gas $components(pH,\;PCO_2,\;PO_2,\;HCO_3^-,\;O_2SAT,\;BE)$, red blood cell, hematocrit, hemoglobin, white blood cell and subsets(neutrophil, basophil, eosinophil. lymphocyte, monocyte), total T cells, helper T cells, suppressor T cells, Th/Ts ratio, total B cells, serum immunoglobulin levels (IgG, IgA, IgM, IgD, IgE), Cytokines(Interlukin$-1{\beta}$, -2, -4, 2 receptor, -6 and ${\gamma}$-interferon), NK cells were measured. Collected with data were analyzed statistically by repealed measured ANOVA. The pattern of change between two groups for hematocrit, hemoglobin, suppressor T cells, interleukin-6, ${\gamma}-interferon$, NK cells at post-2 weeks and BE, lymphocyte, basophil at post-4 weeks was significantly different(p<0.05) And also the pattern of change over time for ${HCO_3}^-$(2 wks vs 4 wks), WBC, neutrophil, lymphocyte(0 wks vs 2 wks and 2 wks vs 4 wks) was significantly different(p<0.05). In summary, these data suggest that negative therapy at back meridian points had an effect on blood gas components and immune functions in male college students because practicing negative therapy at back meridian points was not associated with changes of all blood gas components and immune factors but associated with changes of BE, hematocrit, hemoglobin, WBC. neutrophil, lymphocyte, interleukin-6. ${\gamma}-interferon$, NK cells.

The mulberry tree (Morus alba L.) has been traditionally used in Chinese medicine to treat inflammatory diseases. We investigated the effects of bioconversion on different components of the mulberry tree, and determined changes in the physiological activities. Ethyl acetate-soluble fractions of five different segments (fruit, Mori Fructus; leaf, Mori Folium; twig, Mori Ramulus; root, Mori Cortex; and mistletoe, Loranthi Ramulus) of the mulberry tree show enhanced anti-oxidant effects in the 2,2-diphenyl-1-picrylhydrazyl, and 2,2'-azinobis-(3-ethylvenzothiazoline-6-sulfonic acid) assays, and enhanced anti-inflammatory effects of lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production in RAW 264.7 macrophages, after being treated with a crude enzyme extract from Aspergillus kawachii, in the following order of activity: Mori Folium>Mori Cortex>Mori Ramulus>Mori Fructus>Loranthi Ramulus. Ethyl acetate- soluble fraction of mulberry leaves (Mori Folium) that underwent bioconversion was most effective, and was devoid of any cytotoxicity. The fraction was also effective against mRNA expression of LPS-induced pro-inflammatory cytokines, such as inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis $factor-{\alpha}$, $interleukin-1{\beta}$, and interleukin-6. In addition, the fraction was effective in LPS-induced phosphorylation of mitogen-activated protein kinases and IKK, and $I{\kappa}B$ degradation, followed by translocation of the nuclear $factor-{\kappa}B$ from the cytoplasm to the nucleus. Thus, bioconversion increased the anti-oxidative and anti-inflammatory activities of the mulberry leaf.

In this study, an evaluation of the anti-inflammatory effect of ferulic acid isolated from Tetragonia tetragonioides in lipopolysaccharide (LPS) simulated RAW 264.7 cells was made. The chemical structure of the active compound was elucidated by $^1H$-NMR, $^{13}C$-NMR, and FAB-MS, and was confirmed to be ferulic acid. Ferulic acid was purified via open column chromatography with Sephadex LH-20 and MCI gel CHP-20. To test the anti-inflammatory effect of ferulic acid, LPS-stimulated RAW 264.7 cells were treated in subsequent experiments with different concentrations of ferulic acid (5, 10, and $25{\mu}g/mL$) and the levels of inflammatory cytokines and enzymes were also measured by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay. Cell viability was above 95% at acid concentrations ranging from $5-25{\mu}g/mL$. The results showed that 30% of the production of nitric oxide and 66% of prostaglandin $E_2$ were inhibited by $25{\mu}g/mL$ of ferulic acid, it also inhibited the protein expression of both inducible nitric oxide synthase and cyclooxygenase-2 by 70%. Additionally, it inhibited the production of the pro-inflammatory cytokines, tumor necrosis factor-${\alpha}$, interleukin-6, and interleukin-$1{\beta}$ by 40, 75, and 77%, respectively. According to these results, the anti-inflammatory activity of ferulic acid was demonstrated via his implication in the inhibition of the expression and secretion of inflammatory substances in LPS-stimulated RAW 264.7 cells. Therefore, we concluded that ferulic acid can be used as a functional additive having anti-inflammatory activity.

In this study we aim to extensively investigate the anti-influenza virus immune responses in human pharyngeal epithelial cell line (Hep-2) and evaluate the protective role of Toll-like receptor (TLR) ligands in seasonal influenza A H1N1 (sH1N1) infections in vitro. We first investigated the expression of the TLRs and cytokines genes in resting and sH1N1 infected Hep-2 cells. Clear expressions of TLR3, TLR9, interleukin (IL)-6, tumour necrosis factor (TNF)-${\alpha}$ and interferon (IFN)-${\beta}$ were detected in resting Hep-2 cells. After sH1N1 infection, a ten-fold of TLR3 and TLR9 were elicited. Concomitant with the TLRs activation, transcriptional expression of IL-6, TNF-${\alpha}$ and IFN-${\beta}$ were significantly induced in sH1N1-infected cells. Pre-treatment of cells with poly I:C (an analog of viral double-stranded RNA) and CpG-ODN (a CpG-motif containing oligodeoxydinucleotide) resulted in a strong reduction of viral and cytokines mRNA expression. The results presented indicated the innate immune response activation in Hep-2 cells and affirm the antiviral role of Poly I:C and CpG-ODN in the protection against seasonal influenza A viruses.

Scutellaria baicalensis Georgi, which has been known to be able to clear away heat and remove dampness, was used for febrile disease. It is now clear that Advanced glycation end products (AGEs) play major roles in the pathogenesis of diabetic complications such as atherosclerosis. In this study, we examined whether Scutellaria baicalensis Georgi suppress the AGE mediated inflammatory responses in the THP-1 cells. AGE treatment increased the gene expression of pro-inflammatory cytokines such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), monocyte chemotactic protein-1 (MCP-1) and cyclooxygenase-2 (COX-2). Reverse transcriptase-polymerase chain reaction and Western blot analysis revealed that S. baicalensis had inhibitory effects on the expression of pro-inflammatory genes and protein levels in AGE-treated THP-1 cells. S. baicalensis had also reduced the production of ROS in the AGE-treated THP-1 cells. These results suggest that S. baicalensis has inhibitory effects for the development of diabetic vascular complication.

Purpose : Panax ginseng(PG) is considered to have salutary effects and stimulant actions on physical capacity. However, the effects of PG on the inflammatory cytokine secretion and hypoxia condition are still not understood. This study wasto elucidate the effect of PG on inflammatory cytokine secretion such as interleukin (IL)-1, IL-6, granulocyte macrophage colony stimulating factor (GM-CSF), and tumor necrosis factor $(TNF)-{\alpha}$. Also, the effects on the expression of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1 (HIF-1) were measured. Methods : The water extract of PG was administrated to HMC-1 cells before phorbol myristate acetate (PMA)+A23187 treatment. $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, GM-CSF, and VEGF secretion were measured by a modified enzyme-linked immunosorbent assay (ELISA). HIF-1 activation was measured by transcription factor enzyme-linked immunoassay (TF-EIA) Results : PG significantly decreased secretion of $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, and GM-CSF in PMA+A23187-induced HMC-1 cells. VEGF secretion was not changed but HIF-1 activation was decreased by the treatment of PG. Conclusions : PG inhibited the secretion of inflammatory cytokines, which impliesPG might contribute to treatment of mast cell-mediated inflammatory disease. Also, PG inhibited PMA+A23187-induced $HIF -1{\alpha}activation}$ and DNA-binding activity for HIF-1. Therefore, these data demonstrate that PG modulates inflammatory cytokines through inhibition of $HIF-1{\alpha}activation}$ activation.

FK506 binding protein 12 (FK506BP) belongs to a family of immunophilins, and is involved in multiple biological processes. However, the function of FK506BP in corneal disease remains unclear. In this study, we examined the protective effects on dry eye disease in a Botulinum toxin A (BTX-A) induced mouse model, using a cell-permeable PEP-1-FK506BP protein. PEP-1-FK506BP efficiently transduced into human corneal epithelial cells in a time- and dose-dependent manner, and remained stable in the cells for 48 h. In addition, we demonstrated that topical application of PEP-1-FK506BP was transduced into mouse cornea and conjunctiva by immunohistochemistry. Furthermore, topical application of PEP-1-FK506BP to BTX-A-induced mouse model markedly inhibited expression levels of pro-inflammatory cytokines such as interleukin-$1{\beta}$ (IL-$1{\beta}$), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and macrophage inhibitory factor (MIF) in corneal and conjunctival epithelium. These results suggest PEP-1-FK506BP as a potential therapeutic agent for dry eye diseases.

Background: Compound K (CK) is an active metabolite of ginseng saponin, ginsenoside Rb1, that has been shown to have ameliorative properties in various diseases. However, its role in inflammation and the underlying mechanisms are poorly understood. In this report, the antiinflammatory role of CK was investigated in macrophage-like cells. Methods: The CK-mediated antiinflammatory mechanism was explored in RAW264.7 and HEK293 cells that were activated by lipopolysaccharide (LPS) or exhibited overexpression of known activation proteins. The mRNA levels of inflammatory genes and the activation levels of target proteins were identified by quantitative and semiquantitative reverse transcription polymerase chain reaction and Western blot analysis. Results: CK significantly inhibited the mRNA expression of inducible nitric oxide synthase and tumor necrosis factor-${\alpha}$ and morphological changes in LPS-activated RAW264.7 cells under noncytotoxic concentrations. CK downregulated the phosphorylation of AKT1, but not AKT2, in LPS-activated RAW264.7 cells. Similarly, CK reduced the AKT1 overexpression-induced expression of aldehyde oxidase 1, interleukin-$1{\beta}$, interferon-${\beta}$, and tumor necrosis factor-${\alpha}$ in a dose-dependent manner. Conclusion: Our results suggest that CK plays an antiinflammatory role during macrophage-mediated inflammatory actions by specifically targeting the AKT1-mediated signaling pathway.

Numerous studies have revealed the importance of tumor-derived exosomes in rectal cancer (RC). This study aims to explore the influence of tumor-derived exosomal integrin beta-1 (ITGB1) on lung fibroblasts in RC along with underlying mechanisms. Exosome morphology was observed using a transmission electron microscope. Protein levels of CD63, CD9, ITGB1, p-p65 and p65 were detected using Western blot. To determine ITGB1's mRNA expression, quantitative real-time polymerase chain reaction was used. Moreover, levels of interleukin (IL)-8, IL-1β, and IL-6 in cell culture supernatant were measured via commercial ELISA kits. ITGB1 expression was increased in exosomes from RC cells. The ratio of p-p65/p65 as well as levels of interleukins in lung fibroblasts was raised by exosomes derived from RC cells, while was reduced after down-regulation of exosomal ITGB1. The increased ratio of p-p65/p65 as well as levels of pro-inflammatory cytokines caused by exosomes from RC cells was reversed by the addition of nuclear factor kappa B (NF-κB) inhibitor. We concluded that the knockdown of RC cells-derived exosomal ITGB1 repressed activation of lung fibroblasts and the NF-κB pathway in vitro.

Objective: The aim of this study was to measure the concentrations of cytokines contained in the hydrosalpingeal fluid and to evaluate the effect on the mouse embryo development with the different cytokine concentration. Methods: The hydrosalpingeal fluids (HSF) were collected during the surgery for hydrosalpinx which was confirmed by hysterosalphingogram. The cytokines in HSF including interleukin (IL)-$1{\alpha}$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-$\alpha$, Interferon-$\gamma$ (IFN-$\gamma$), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), monocyte chemotactic protein-1 (MCP-1) were measured by ELISA method. HSF were added up to culture media with 5%, 10%, and 30% concentrations. The blastulation rates were compared. Results: IL-$\alpha$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-$\alpha$, IFN-$\bamma$, VEGF, EGF, and MCP-1 were detected, but the concentrations were different from each sample. IL-6 and IL-10 were increased in HSF-1 group, and IFN-$\gamma$, MCP-1, VEGF were increased in HSF-2 compared with normal serum range. The Th1/Th2 ratio of HSF-2 (IFN-$\gamma$:IL10) was highly elevated to 61.64, compared with that of HSF-1 (3.69). The blastulation rate was significantly decreased in HSF-2 group (27.7%) compared those of the HSF-1 group (74%) and control group (76.7%). It showed the trend that the blastulation rate was decreased depending on the concentration HSF of culture media in HSF-2 group, but it was not statistically significant. Conclusion: The composition and concentration of cytokines in each HSF were different, and increased proinflammatory cytokines in HSF might be associated with poor embryonic development. Further study will be needed about the effect of each cytokines in HSF.
