ABSTRACT

Objective:To investigate the effect and mechanism of Fuzheng Touxie prescription (FZTX) on the immune homeostasis of drug-resistant <italic>Pseudomonas aeruginosa</italic> lung infection in rats at different time points. Method:A total of 168 rats were divided into a blank group (<italic>n</italic>=8),a model group (<italic>n</italic>=40),a Touxie (TX) group (<italic>n</italic>=40),an early Fuzheng (FZ) group (<italic>n</italic>=40), and a delayed FZ group (<italic>n</italic>=40). The blank group was given distilled water by gavage, the model group was given distilled water by gavage after infection,the TX group was given clear heat and penetrate evil drug free decoction granules(3.5 g·kg<sup>-1</sup>) by gavage after infection, the early FZ group was given Fuzheng Touxie whole formula free decoction granules(10.75 g·kg<sup>-1</sup>) by gavage after infection, the delayed FZ group was given clear heat and penetrate evil drug free decoction granules by gavage after infection, on the third day plus Fuzheng drug free decoction granules[(3.5+10.75) g·kg<sup>-1</sup>] by gavage, the three treatment groups were gavaged twice a day, 2 mL each time .Each drug treatment group was divided into five groups according to five time points (3 h,1 d,3 d,5 d, and 7 d), with eight rats in each group. The levels of tumor necrosis factor-<italic>α</italic>(TNF-<italic>α</italic>),high mobility group protein 1(HMGB1),interleukin-10(IL-10), and tumor necrosis factor -<italic>α</italic>-induced protein-8-like2 (TIPE2) were measured by enzyme-linked immunosorbent assay (ELISA), and HMGB1 protein expression level by Western blot. Result:At 3 h,the TNF-<italic>α</italic> content in the drug treatment groups was higher than that in the blank group and the model group (<italic>P</italic><0.05). At 3 d,the TNF-<italic>α</italic> content in the early FZ group and the delayed FZ group was lower than that in the model group (<italic>P</italic><0.05) and the TX group (<italic>P</italic><0.05). At 1 d,the HMGB1 content in the TX group and the delayed FZ group was higher than that in the model group (<italic>P</italic><0.05). At 5 d,the HMGB1 content was lower in the delayed FZ group than in the model group (<italic>P</italic><0.05). At 7 d,HMGB1 protein expression in the model group was higher than that in the blank group (<italic>P</italic><0.05) and the early FZ group (<italic>P</italic><0.05). At 3 d,the IL-10 content was significantly higher in both the early FZ group and the delayed FZ group than that in the model group (<italic>P</italic><0.05). At 5 d,the IL-10 content was higher in the early FZ group than that in the TX group (<italic>P</italic><0.05). At 7 d,the IL-10 content in the early FZ group and the delayed FZ group was lower than that in the TX group (<italic>P</italic><0.05). At 5 d,the TIPE2 content in the early FZ group was lower than that in the model group (<italic>P</italic><0.05). At 7 d,the TIPE2 content in the TX group and the delayed FZ group was lower than that in the model group (<italic>P</italic><0.05). Conclusion:FZTX or modified prescription can promote the inflammatory response to eliminate pathogenic bacteria in the early stage and suppress the inflammatory response in the late stage to avoid the inflammatory cascade effect and lung tissue damage,indicating that Fuzheng drugs have an important role in maintaining the immune homeostasis of the body after infection.

ABSTRACT

The aim of this paper was to explore the key genes and pathogenesis of ischemic stroke(IS) by bioinformatics, and predict the potential traditional Chinese medicines for IS. Based on the gene-chip raw data set of GSE22255 from National Center of Biotechnology Information(NCBI), the article enrolled in 20 patients with ischemic stroke and 20 sex-and age-matched controls, and differentially expressed genes(DEGs) were screened based on R language software. The DAVID tool and R language software were used to perform gene ontology(GO) biological process enrichment analysis and Kyoto encyclopedia of genes and gnomes(KEGG) pathway enrichment analysis. The DEGs were imported into STRING to construct a protein-protein interaction network, and the Molecular Complexity Module(MCODE) plug-in of Cytoscape software was used to visualize and analyze the key functional modules. Moreover, the core genes and the medical ontology information retrieval platform(Coremine Medical) were mapped to each other to screen the traditional Chinese medicines and construct drug-active ingredient-target network. Compared with healthy controls, 14 DEGs were obtained, of which 12 genes were up-regulated and 2 genes were down-regulated. DEGs were mainly involved in immune response, inflammatory process, signal transduction, and cell proliferation regulation. The interleukin-17(IL-17), nuclear factor kappaB(NF-κB), tumor necrosis factor(TNF), nucleotide binding oligomerization domain(NOD)-like receptor and other signaling pathways were involved in KEGG pathway enrichment analysis. The key modules of the DEGs-encoding protein interaction network mainly focused on 7 genes of TNF, JUN, recombinant immediate early response 3(IER3), recombinant early growth response protein 1(EGR1), prostaglandin-endoperoxide synthase 2(PTGS2), C-X-C motif chemokine ligand 8(CXCL8) and C-X-C motif chemokine ligand 2(CXCL2), which were involved in biological processes widely such as neuroinflammation and immunity. TNF and JUN were the key nodes in this module, which might become potential biological markers for diagnosis and prognosis evaluation of IS. The potential traditional Chinese medicines for the treatment of IS includes Salviae Miltiorrhizae Radix et Rhizoma, Croci Stigma, Scutellariae Radix, and Cannabis Fructus. The occurrence of stroke was the result of multiple factors. Dysregulation of genes and pathways related to immune regulation and inflammation may be the key link for the development of IS. This study provided research direction and theoretical basis for further exploring the mechanism of action of traditional Chinese medicine in the treatment of IS and searching for potential drug targets.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of Qiguiyin Decoction, QGYD) on multidrug-resistant Pseudomonas aeruginosa infection in Sprague-Dawley (SD) rats.</p><p><b>METHODS</b>A pseudomonal infection model in SD rats was established by injecting multidrug-resistant P. aeruginosa intraperitoneally. Infected rats were randomized into four groups treated with Pure water, QGYD, ceftazidime, or combined QGYD and ceftazidime. Blood samples were obtained from the abdominal aorta. Serum was then collected and analyzed by peptide array for immune responsiveness to multidrug-resistant beta-lactamase proteins, including Verona integronen-coded metallo-beta-lactamase 1 (VIM-1), Sao Paulo metallo-beta-lactamase 1 (SPM-1), and Temoniera (TEMs). Blood levels of interleukin-1β (IL-1β), interleukin-4 (IL-4), and interferon-γ (IFN-γ) were assessed by enzyme-linked immunosorbent assay.</p><p><b>RESULTS</b>QGYD enhanced antibody reactivity against VIM-1 [epitopes 7-11 and 36-40] and TEM-1 [epitopes 26-27, 52-55, and 66-70]. QGYD treatment restored the compromised antibody reactivity against VIM-1 [epitopes 53-54 and 56-58] and SPM-1 [epitopes 16-19 and 82-85] following pseudomonal infection. Serum levels of IL-1β and Th1/Th2 in the rats were significantly elevated following pseudomonal infection (P<0.05 orP<0.01). In contrast, QGYD and combination QGYD and ceftazidime treatment restored the elevated serum IL-1β and Th1/Th2 levels to normal (P>0.05).</p><p><b>CONCLUSIONS</b>QGYD improves the immune response to pseudomonal infection in rats by stimulating the production of protective antibodies against drug-resistant proteins VIM-1, SPM-1, and TEM-1. In addition, it protects the immune system and maintains immune responsiveness by restoring IL-1β and Th1/Th2 levels.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the role and mechanism of the Fas/Fas ligand (FasL) system and its downstream signaling pathway related to the progression of alcoholic steatohepatitis and liver fibrosis.</p><p><b>METHODS</b>Eighteen C57BL/6J mice were randomly divided into three groups: controls; alcoholic steatohepatitis model, given four-weeks of a 4% ethanol-containing Lieber-DeCarli liquid diet; alcoholic steatohepatitis and liver fibrosis model, given the four-week alcohol diet followed by twice weekly intraperitoneal injections of carbon tetrachloride (5% olive oil solution; 2 mL/kg dose) during the fifth to eighth weeks. Mice in the model groups were sacrificed at the end of week 4 and 8, respectively, along with control mice for comparative analyses. Liver tissue sections were evaluated for hepatocellular apoptosis by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay. The mRNA expression of Fas, FasL, cysteine aspartate-specific proteases 3 (caspase 3), and cytochrome P450 2E1 (CYP 2E1) in liver tissues was detected by reverse transcription (RT)-PCR, visualized by ethidium bromide staining, and normalized to the gray-value of GAPDH expression. The protein expression of Fas and caspase 3 were detected by western blotting (b-actin normalized), and of FasL and CYP 2E1 by immunohistochemistry staining. Intergroup differences and statistical significance were evaluated by single factor analysis of variance and the least squares difference-t test or the Kruskal-Wallis H test and the Mann-Whitney U test.</p><p><b>RESULTS</b>The number of apoptotic cells in the liver sections was significantly higher in both model groups with alcoholic steatohepatitis (vs. controls) and the amount in the alcoholic steatohepatitis plus liver fibrosis model was significantly higher than that in the model with only alcoholic steatohepatitis. In addition, activation of Fas, FasL and its downstream signaling pathway showed an increasing trend with extent of liver injury. The hepatic mRNA (by RT-PCR) and protein (by western blotting) normalized expression levels in the controls, alcoholic steatohepatitis models, and alcoholic steatohepatitis plus liver fibrosis models were, respectively: Fas mRNA: 0.50+/-0.05, 0.61+/-0.10, 0.76+/-0.03 (H=12.137, P less than 0.05), protein: 0.52+/-0.14, 0.86+/-0.10, 0.99+/-0.09 (F=12.758, P less than 0.01); FasL mRNA: 0.31+/-0.03, 0.53+/-0.02, 1.02+/-0.04 (F=153.260, P less than 0.01); caspase 3 mRNA: 0.86+/-0.11, 0.85+/-0.05, 1.33+/-0.16 (F=8.740, P less than 0.01), protein: 0.40+/-0.03, 0.69+/-0.06, 1.02+/-0.10 (F=90.785, P less than 0.01); CYP 2E1 mRNA: 0.72+/-0.14, 1.00+/-0.15, 1.30+/-0.20 (H=4.713, P less than 0.01). The changes in hepatic FasL and CYP 2E1 expression detected by immunohistochemistry were consistent with the mRNA expression.</p><p><b>CONCLUSION</b>Activation of Fas/FasL and its downstream signaling pathway, which induces hepatocellular apoptosis, contributes to the development of alcoholic steatohepatitis and liver fibrosis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To create a convenient method to establish an alcoholic liver fibrosis model in mice and use it to explore the putative pathogenic mechanisms involving the immunomodulatory proteins osteopontin (OPN) and transforming growth factor-betal (TGF-beta1).</p><p><b>METHODS</b>Forty C57BLI6J mice were fed the Lieber-DeCarli 4% ethanol-containing liquid diet for four weeks, followed by an additional four weeks of the 4% ethanol diet combined with intraperitoneal injection of carbon tetrachloride (CC14 5% solution in olive oil; 2ml/ kg body weight, 2 times/week) to induce alcoholic liver fibrosis. Control groups (n = 6 each) included: normal diet; normal diet plus CCl4 injections; ethanol diet alone; ethanol diet plus solvent (olive oil) injections. Model establishment was monitored by sacrificing six mice at model inception (week 0), and weeks 4, 5, 6, 7, and 8 of modeling to collect liver tissues and blood for histological and biochemical analyses. Extent of hepatic steatosis, inflammation, and fibrosis was assessed by hematoxylin-eosin and Masson staining. Liver function markers, serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, were tested by automated enzymatic assays. Alpha-smooth muscle actin (alpha-SMA) expression was detected by immunohistochemistry. The mRNA and protein expression of OPN and TGF-beta1 was detected by real-time quantitative reverse transcription-PCR and western blotting, respectively. Significance of differences between multiple groups was assessed by one-way ANOVA analysis followed by least significant difference t-test or Kruskal-Wallis H test followed by the Mann-Whitney U test.</p><p><b>RESULTS</b>Compared to the control groups, the group of mice administrated ethanol and CCl4 developed mild to moderate hepatic steatosis at week 4 of modeling, progressive necroinflammation and perisinusoidal and portal fibrosis from weeks 5-8, and irregular necrosis and bridging fibrosis at week 8. In addition, the model group showed progressive up-regulation of a-SMA expression in the activated hepatic stellate cells (HSCs) and fibrotic areas from weeks 5-8. Both hepatic OPN and TGF-beta1 showed significantly increasing trends in mRNA and protein expressions from weeks 5-8 (OPN mRNA: 1.83 +/- 0.25, 2.94 +/- 0.19, 3.45 +/- 0.31, and 5.99 +/- 0.17 (F= 476.27, P < 0.001); OPN protein: 0.52 +/- 0.06, 1.02 +/- 0.10, 1.52 +/- 0.11 and 1.50 +/- 0.08 (F= 298.03, P< 0.001); TGF-beta1 mRNA: 13.19 +/- 0.40, 3.31 +/- 0.28, 1.58 +/- 0.18 and 2.08 +/- 0.26 (F= 85.55, P < 0.001); TGF-P31 protein: 1.26 +/- 0.16, 0.96 +/- 0.12, 1.09 +/- 0.25 and 1.10 +/- 0.20 (F = 43.64, P < 0.001).</p><p><b>CONCLUSION</b>Feeding C57BL/6J mice the Lieber-DeCarli ethanol-containing liquid diet combined with CCl4 intraperitoneal injection is a convenient method to establish a model of alcoholic liver fibrosis within a relatively short amount of time (eight weeks). Progression of alcoholic liver fibrosis is accompanied by increased hepatic expression of OPN and TGF-beta1, which may contribute to the pathogenic mechanism of this disease and may be targets of future molecular therapies.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the association of single nucleotide polymorphisms (SNPs) in the interleukin 17 (IL-17) gene and serum protein levels in patients with chronic hepatitis C virus (HCV) infection.</p><p><b>METHODS</b>A total of 228 patients with chronic HCV infection and 81 healthy controls were enrolled in the study. The frequencies of IL-17 rs8193036 and rs2275913 polymorphisms were detected by the TaqMan SNP genotyping assay. Serum levels of IL-17 protein were detected by ELISA. Pairwise comparisons were made by the Chi-square test, and the significance of between-group differences was assessed by the Student's t-test with P less than 0.05.</p><p><b>RESULTS</b>The patients with chronic HCV infection and the healthy controls showed similar frequencies of the rs8193036 C/T allele (x2 = 1.428, P = 0.232) and the rs2275913 A/G allele (x2 = 0.106, P = 0.744). In addition, the two groups showed similar distribution of the rs8193036 CC (chronic HCV infection: 46.49% vs. healthy controls: 41.98%), CT (45.61% vs. 44.44%) and TT (7.89% vs. 13.58%) genotypes (x2 = 2.346, P = 0.309), and of the rs2275913 AA (16.23% vs. 13.58%), AG (48.25% vs. 50.62%) and GG (35.53% vs. 35.80%) genotypes (x2 = 0.340, P = 0.844). Subgroup analysis of chronic HCV infection patients stratified according to HCV genotypes 1 and 2 showed no differences in the distribution of rs8193036 and rs2275913 alleles (x2 = 1.127, P = 0.288; x2 = 1.088, P = 0.297) and genotypes (x2 = 2.825, P = 0.246; x2 = 0.970, P = 0.616). However, the chronic HCV infection group did show significantly higher levels of serum IL-17 than the controls (97.67+/-39.68 vs. 71.60+/-19.78 pg/ml, t = 2.414, P = 0.033).</p><p><b>CONCLUSION</b>Chronic HCV infection is associated with increased serum IL-17; however, the IL-17 polymorphisms rs8193036 and rs2275913 were not associated with chronic HCV infection susceptibility in this study's Chinese cohort.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To elucidate the effect of targeted gene modulation of peroxisome proliferator activated receptor gamma (PPARg) on hepatocellular apoptosis in nutritional fibrotic steatohepatitis in mice. C57BL/6J mice were fed with high fat, methionine-choline deficient (MCD) diet for 8 weeks to induce fibrotic steatohepatitis. Mice fed the MCD diet were treated with adenovirus carrying PPARg (Ad-PPARg), adenovirus-beta-galactosidase (Ad-LacZ), Ad-PPARg plus PPARg agonist rosiglitazone, or PPARg antagonist 2-chloro-5-nitro- benzanilide (GW9662), respectively. H and E stain was performed for observation of hepatocellular apoptosis, hepatic steatosis, inflammation and fibrosis in the liver sections. The expression levels of mRNA and protein of PPARg and apoptosis related genes, Fas, Fas Ligand (FasL), B cell lymphoma/leukemia-2 (Bcl-2), Bcl-2 associated X protein (Bax) and cysteine-containing aspartate-specific proteases-3 (caspase-3) were detected by real-time RT-PCR and Western blot assay, respectively.</p><p><b>RESULTS</b>Mice fed with MCD diet for 8 weeks showed severe hepatic injury including steatosis, hepatocellular apoptosis, inflammatory infiltration and fibrosis, concomitancy with enhanced expression of pro-apoptosis genes, Fas, FasL, Bax and caspase-3 and increased expression of anti-apoptosis gene Bcl-2, by comparing with the control group. The mRNA expression levels of these genes were 3.59+/-0.35 vs 1.11+/-0.37, 4.37+/-1.03 vs 1.09+/-0.33, 4.27+/-0.48 vs 1.03+/-0.10, 4.93+/-0.67 vs 1.12+/-0.24 and 3.95+/-0.34 vs 1.20+/-0.19, and LSD-t values were 2.49, 3.28, 3.25, 3.80 and 2.75, as compared with the control group, P is less than 0.01; the protein expression levels were 1.96+/-0.07 vs 0.45+/-0.07, 0.53+/-0.07 vs 0.22+/-0.02, 1.32+/-0.06 vs 0.59+/-0.03, 1.51+/-0.23 vs 0.36+/-0.09 and 0.57+/-0.01 vs 0.29+/-0.01, and LSD-t values were 1.51, 0.31, 0.73, 1.14 and 0.28, P is less than 0.01. Administration of PPARg agonist rosiglitazone and/or Ad-PPARg significantly ameliorated hepatic steatosis, hepatocellular apoptosis, necro inflammation and fibrosis. These effects were associated with repressed expression of pro-apoptosis genes and up-regulated expression of anti-apoptosis gene. After rosiglitazone treatment, the mRNA expression levels were 3.78+/-0.58, 3.66+/-0.83, 3.04+/-0.37, 2.54+/-0.62 and 4.42+/-0.42, and LSD-t values were 0.18, 0.71, 1.23, 2.39 and 0.46, as compared with MCD group, the P values were 0.627, 0.241, less than 0.01, less than 0.01 and 0.278, the protein expression levels were 1.06+/-0.03, 0.30+/-0.01, 0.70+/-0.05, 1.19+/-0.30 and 0.90+/-0.01, and LSD-t values were 0.90, 0.23, 0.62, 0.31 and 0.34, the P values were less than 0.01, less than 0.01, less than 0.01, 0.122, less than 0.01. After Ad-PPARg treatment, the mRNA expression levels were 2.31+/-0.16, 2.71+/-0.23, 2.52+/-0.27, 1.79+/-0.32 and 5.97+/-0.72, and LSD-t values were 1.28, 1.66, 1.75, 3.13 and 2.02, as compared with MCD group, P is less than 0.05; the protein expression levels were 1.73+/-0.07, 0.43+/-0.04, 1.01+/-0.08, 1.31+/-0.10 and 1.56+/-0.04, and LSD-t values were 0.23, 0.10, 0.30, 0.20 and 0.99, with P values equal 0.009, 0.01, less than 0.01, 0.322 and less than 0.01.</p><p><b>CONCLUSIONS</b>This study provided evidences for the protective role of activation and overexpression of PPARg in ameliorating hepatocellular apoptosis in mice with hepatic fibrosing steatohepatitis.</p>

ABSTRACT

<p><b>OBJECTIVE</b>Our previous study indicated that the death receptor Fas played a key role on hepatocyte apoptosis in nutritional steatohepatitis in mice. This study aimed to explore whether Fas mutation accelerated hepatic steatosis and inflammatory infiltration in methionine-choline deficient (MCD) diet feeding mice.</p><p><b>METHODS</b>Mice homozygous for the lymphoproliferation spontaneous mutation (C57BL/6J-Faslpr) and wild type C57BL/6J mice were fed with MCD diet for three weeks to induce non-alcoholic steatohepatitis (NASH). Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG) and total cholesterol (TC) levels were detected by an Olympus AU5400 automatic chemical analyzer. The role of Fas gene mutation on NASH was assessed by comparing the severity of hepatic steatosis and inflammation in the liver sections, the mRNA and protein expressions of hepatic inflammatory and fibrogenesis related factors, proliferating cell nuclear antigen (PCNA) and transforming growth factor beta 1 (TGFb1).</p><p><b>RESULTS</b>The serum ALT levels of the wild type and Faslpr mice fed with MCD were significant higher than that of the control mice (126.33+/-10.50 U/L vs (25.00+/-10.14) U/L, (160.33+/-48.29) U/L vs (18.33+/-9.08) U/L, with the LSD-t value 12.02, 5.08 respectively, the P value<0.001, 0.007 respectively. The serum ALT levels showed no significant difference between the Faslpr and wild type mice fed with MCD, with the LSD-t value 1.19, the P value 0.229. The serum AST, TG and TC levels showed neithere significant difference among the four groups. MCD diet induced hepatic steatosis and inflammatory infiltration in both of the wild type and Faslpr mice. Especially, severer hepatic injury was observed in Faslpr mice as compared with wild type mice. The mRNA expression levels of cell proliferation factor PCNA and fibrogenesis growth factor TGF b1 in wild type mice fed with MCD were significantly higher than that of the control mice (2.84+/-0.73, 2.77+/-0.54 vs 1.31+/-0.18, 0.89+/-0.18), with the LSD-t value 4.99, 8.08 respectively, the P value 0.001, <0.001 respectively. The mRNA expression levels of PCNA and TGFb1 in Faslpr mice fed with MCD were significantly higher than that of the Faslpr control mice and the wild type mice fed with MCD (5.57+/-1.13, 5.73+/-0.89 vs 1.04+/-0.16, 0.85+/-0.11 and 2.84+/-0.73, 2.77+/-0.54), with the LSD-t value 10.15, 13.19 and 5.33, 6.91 respectively, the P value<0.001. The protein expressions levels of PCNA and TGFb1 were concordant with the mRNA.</p><p><b>CONCLUSIONS</b>Faslpr promoted hepatic steatosis and inflammatory infiltration in mice fed with MCD diet, which might associated with excessive release of cell proliferative, inflammatory and fibrogenesis factors.</p>
