OBJECTIVE: To establish a rat model of nonalcoholic fatty liver disease (NAFLD) using high-fat diet, and to dynamically observe the influence of the changes in gut microbiota on the development and progression of NAFLD in rats during and after modeling.METHODS: Sprague-Dawley rats were given high-fat diet to establish the model of NAFLD, and these rats were randomly divided into high-fat group, antibiotic pretreatment group, antibiotic treatment group, restricted diet group, and control group. The rats were sacrificed in different feeding periods, and 16sRNA fluorescent quantitative PCR was used to analyze the changes in ileocecal microbiota in rats. The liver pathological scores were determined, and enzymatic colorimetry was used to measure blood lipid level in serum and liver homogenate. The sample mean t-test was used for comparison between groups.RESULTS: Compared with the high-fat group, the restricted diet group showed the most significant improvements in quality of life and biochemical parameters. In the restricted diet group, the number of probiotics (Bifidobacterium and Lactobacillus) at the end of the ileum gradually increased and tended to increase over the time of intervention, and the most significant difference between this group and the high-fat group occurred at the 10th week (Bifidobacterium: 0.91±0.23 vs 0.28±0.12, P < 0.05; Lactobacillus: 0.78±0.04 vs 0.21±0.03, P < 0.05), while the number of enterococci decreased. There were no significant differences in enteric bacilli between groups (all P > 0.05). At the 10th week, the liver pathological scores in the control group, antibiotic treatment group, and restricted diet group were 1.13±1.74, 4.86±0.86, and 2.94±1.91, respectively, significantly lower than 7.09±2.03 in the high fat group (all P < 0.05).CONCLUSION: Diet structure change and antibiotic intervention can adjust gut microecology, alleviate the lesions of NAFLD, and thus provide new strategies for the prevention and treatment of NAFLD from the perspective of microecology.

Bu-Shen-Ning-Xin Decoction (BSNXD) administration has alleviated the early pathologic damage of atherosclerosis by inhibiting the adhesion molecule expression and upregulating the estrogen receptor (ER) b expression in endothelial cells, and increasing the serum nitric oxide (NO) level without any effect on serum lipid status, endometrium and fat deposition in liver in ovariectomized rabbits. The BSNXD-derived serum increases ER b expression in the human umbilical vein endothelial cells (HUVECs), and decreases malondialdehyde (MDA) production, and upregulates eNOS expression then increases NO synthesis through ERβ-dependent pathway. NO not only suppresses the LPS-induced NF-kb transcription in HUVECs, but also decreases apoptosis of endothelial cells. The BSNXD-derived serum decreases monocyte chemoattractant protein-1 production, and suppresses cell adhesion molecules (ICAM-1, VCAM-1 and E-selectin) expression in HUVECs injured by oxidized low-density lipoproteins (ox-LDL), and these effects can be abolished by ERβ antagonist (R,RTHC) and NO synthase inhibitor (L-NAME). The BSNXD-derived serum-treated HUVECs supernatant reduces CCR2, LFA-1 and VLA-4 expression in monocytes cell line U937 cells, which in turn inhibits adherence of U937 to injured endothelial cells. NO synthesis increases, and MDA production decreases through ERβ-mediated pathway that suppresses apoptosis and NF-kb activity in endothelial cells that downregulates adhesion molecules expression on endothelial cells via ERβ/NO/NF-kb pathway, and in turn leukocyte adhesion, which suggests BSNXD potential value in prophylaxis atherosclerosis. © 2013 Macmillan Publishers Limited.

Epithelial-mesenchymal transition (EMT) is considered a critical event in cancer cell invasion and metastasis. Emerging evidence has shown that curcumin may prevent or delay the progression of cancer, an effect that may be partially due to its ability to disrupt EMT, yet this has not yet been demonstrated. In this study, we used lipopolysaccharide (LPS) to trigger EMT in MCF-7 and MDA-MB-231 breast cancer cell lines and showed that curcumin inhibited LPS-induced morphological changes, decreased the expression of LPS-induced markers of EMT such as vimentin, and increased the expression of E-cadherin, resulting in the inhibition of in vitro cell motility and invasiveness. We discovered that these actions were mediated through the inactivation of NF-?B-Snail signaling pathways. Our results indicate that curcumin plays an important role in the inhibition of LPS-induced EMT in breast cancer cells through the downregulation of NF-?B-Snail activity. These data provide a new perspective of the anti-invasive mechanism of curcumin, indicating that the effect is partly due to its ability to attack the EMT process.

To investigate the influence of temperature on the expressions of c-kit and PI3K in spermatogonia cultured in vitro at 32 degrees C and 37 degrees C, and provide basic scientific data for the mechanism of spermatogenic impairment due to body temperature (37 degrees C). Isolated spermatogenic cells were cultured in vitro at 32 degrees C and 37 degrees C, and their adherence, proliferation and morphologic changes were observed and recorded under the inverted phase contrast microscope. At 8 days, the spermatogonia were separated by Percoll density gradient centrifugation and the differential adhesion method. The expressions of c-kit and PI3K mRNA and proteins in the separated cells were detected by real time polymerase chain reaction and Western blot, respectively. The c-kit gene was sequenced to identify the occurrence of mutations. Adherence, division and proliferation of the cells were observed in both the 32 degrees C and 37 degrees C groups. The expressions of c-kit and PI3K mRNA and proteins in the spermatogonia were significantly higher in the 32 degrees C group than in the 37 degrees C group (P < 0.05). The 32 degrees C group showed no mutation of c-kit in exon 9, 11 and 13; the 37 degrees C group exhibited no mutation in exon 11 and 13, but possible insertion or deletion mutations in exon 9. Culturing in vitro at 37 degrees C could inhibit the expression of proliferation- and differentiation-related genes in spermatogenic cells and lead to the mutation of the c-kit gene.

To explore the correlation between single nucleotide polymorphisms (SNPs) of interleukin-28B (IL-28B) gene and the susceptibility to primary hepatocellular carcinoma (HCC). A total of 300 histologically confirmed HCC cases (from November 2001 to April 2010) and 310 healthy controls with no history of chronic hepatitis B or hepatocellular carcinoma (2009-2010) were selected from a hospital in Guilin and a hospital in Beijing for this case-control study.139 HCC patients in the case group had complete clinical tracking data. All the subjects were Han Chinese, with no age or gender restrictions.2 ml peripheral blood samples were drawn from each subject with informed consent. SNP of rs12972991, rs4803223, rs8099917 and rs12979860 four loci in IL-28B gene were analyzed by matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF). The frequencies of C allele at rs12972991, G allele at rs8099917 and G allele at rs4803223 were 6.7% (40/598), 7.9% (47/598) and 10.0% (59/588) respectively in case group; all higher than the corresponding frequencies in control group, separately 2.9% (18/618), 4.1% (25/616) and 3.6% (21/608). The differences were statistically significant (χ2=9.542, 7.858, 20.736, P values all<0.05). The above alleles could increase the risk of HCC, and the OR (95%CI) values were separately 1.67 (1.13-2.46), 1.49 (1.08-2.06) and 2.91 (1.79-4.72). The genotype frequencies of AC+CC at rs12972991, GT+GG at rs8099917, GA+GG at rs4803223 were 13.0% (39/299), 14.7% (44/299) and 19.0% (56/296) respectively in case group; while the frequencies were lower in control group, separately 5.8% (18/309), 8.1% (25/308) and 6.6% (20/304). The differences were statistically significant (χ2=9.319, 6.557, 20.948, P values all<0.05). These genotypes may increase the risk of HCC, and the adjusted OR (95%CI) values were 2.24 (1.31-3.83), 1.81 (1.14-2.88) and 2.90 (1.78-4.70), respectively. The stratified analysis of the clinical data indicated that the frequency of genotype GA+GG at rs4803223 was 50.0% (13/26) in patients of tumor thrombosis in portal vein (TTPV), higher than the frequency of genotype AA (21.1%, 23/109). The difference was statistically significant (χ2=8.965, P=0.003). The results suggested that IL-28B gene polymorphisms was correlated to the susceptibility to HCC in Chinese Han ethnic population. Among them, GA + GG genotype at rs4803223 could increase the risk of TTPV in HCC patients.

To investigate the effects of atorvastatin on matrix metalloproteinase-9 (MMP-9) and the tissue inhibitor-1 of matrix metalloproteinase (TIMP-1) levels in bronchoalveolar lavage fluid (BALF) and serum of rats with experimental pulmonary fibrosis. Pulmonary fibrosis was induced by intratracheal administration of bleomycin in 30 female rats, which were further divided into two groups: Group M (without treatment) and Group A (treated with atorvastatin 10 mg/kg); control group (n = 5, Group C) was intratracheally administrated with same volume of saline. Five animals were sacrificed at 2 weeks (M2 and A2), 4 weeks (M4 and A4) and 6 weeks (M6 and A6) after model establishment, respectively. Lung tissue samples were harvested and prepared for HE and Masson's trichrome staining. Concentrations of MMP-9 and TIMP-1 in BALF and serum were measured by ELISA. The severity of inflammation and pulmonary fibrosis was significantly reduced in Group A than that in Group M, especially at week 6. No significant difference was noted in the serum concentrations of MMP-9 and TIMP-1 among the Group M, A and Group C. The BALF concentrations of MMP-9 in Group M2 and M6 were significantly higher than those in Group C (P < 0.01 and 0.05), whereas those in the atorvastatin groups (A2, A4 and A6) were lower than those in M2, M4 and M6. Although the MMP-9 was still higher in Groups A2 and A4 than in the Group C, there was no significant difference in MMP-9 between Group A6 and Group C. TIMP-1 levels in BALF were significantly higher in M4 and M6 than Group C (P < 0.01 and 0.05), there were no significant differences between Group M2 and Group C. The TIMP-1 levels in BALF of atorvastatin groups were significantly lower than those of model groups and control group (P < 0.01 and 0.05), which resulted in a significantly increased ratio of MMP-9 to TIMP-1 in the atorvastatin groups. Atorvastatin inhibits the synthesis and release of MMP-9 and TIMP-1 in the lung tissue of rats with bleomycin-induced pulmonary fibrosis, and has no significant effect on circulating MMP-9 and TIMP-1, which may be associated with the attenuation of experimental pulmonary fibrosis in rats.

To investigate the levels of FasL mRNA in peripheral blood mononualear cells (PBMCs), serum soluble Fas ligand (sFasL) and their regulatory effect on T lymphocyte subsets in patients with severe acute pancreatitis (SAP). Forty-eight patients with pancreatitis were randomly divided into two groups: 20 cases with SAP and 28 cases with mild acute pancreatitis (MAP). Twenty-eight healthy volunteers were selected as control group. The expression of FasL mRNA in PBMCs was detected by real-time quantitative PCR(qRT-PCR), and serum sFasL was measured by ELISA. T lymphocyte subsets in peripheral blood were detected by flow cytometry. Compared with control group and MAP group, FasL mRNA of PBMCs and serum sFasL increased significantly in SAP group (P<0.05), a little increase in MAP group, and there was no significant difference between MAP group and control group (P>0.05). The CD4(+) T cell ratio, CD4(+)/CD8(+) ratio decreased significantly in SAP group (P<0.05) vs control group and MAP group), and they were found negatively related to FasL mRNA, serum sFasL level. The SAP patients showed the significantly increased FasL mRNA of PBMCs and serum sFasL and decreased CD4(+) T-cell ratio, CD4(+)/CD8(+) ratio. FasL may mediate the apoptosis of T lymphocytes.
