Objective To investigate the effects of B.adolescentis and L.acidophilus in treatment of dextran sulphate sodium (DSS)-induced ulcerative colitis(UC) in mice and their potential mechanisms. Methods Seventy-five BABL/C mice were randomly divided into control,saline (NS),B.adolescentis BF0624 treatment (B),L.acidophilus LT0637 treatment (L) and salicylazosulpha-pyridine treatment (S) groups.Except control group,the other four groups were received DSS to induce ulcerative colitis. The weight-loss,fecal trait and bleeding were recorded every day.Colonic length and histological scores were evaluated on day 3,5 and 7.The gene and protein expression of hot shock protein (HSP)70, glucocorticoid receptor (GR),interleukin (IL)-10 and tumor necrosis factor (TNF)-α were detected by Western blot and reverse polymerase chain reaction (RT-PCR) respectively.Results B.adolescentis BF0624 and L.acidophilus LT0637 could relieve the inflammatory reaction of the experimental UC.The DAI scores were 1.84±0.4 in L group on day 3,which was lower than that in NS group (2.8±1.0).The DAI scores in all treatment groups were decreased on day 5.Compared with NS group[(8.1±0.6)cm ], the colon length on day 8 were (9.0±0.6)cm in B group,(9.35±0.6)era in L group and (8.8±1.1)cm in S group (P＜0.05).The colonic mucosa was improved pathohistologically in L group (6.0±1.0) on day 8.The expression of HSP70 and IL-10 in B and L groups were up-regulated and the expression of TNF-α was down-regulated.Conclusions Both B.adolescentis BF0624 and L.acidophilus LT0637 were effective in treatment of acute ulcerative colitis.The potential mechanism of two probiotics may be related with up-regulation of HSPT0 and IL-10 expressions and down-regulation of TNF-α expression.

Objective To compare the quality of life ( QOL) in different family life cycle residents and analyze its influencing factors. Methods Based on the stratified cluster sampling,517 married residents from three communities of Dongguan city were chosen to be investigated by a questionnaire on the general status and the MOS health survey (SF-36).The One-Way ANOVA and Multiple Regression Analysis were used to analyze the data. Result There were significant differences on the seven domains of the SF-36 ex-cept of physical pain in different family life cycle residents (P<0.05) . The scores of different domains at the retirement or senior years were the lowest ( ranging from 37.10-59.81) ,and the scores of different domains at the child-bearing period were highest (ranging from 37.10-59.81). The results of Multiple Linear Stepwise Regression showed that the QOL of different family life cycle residents were influenced by some factors. The influencing factors on PCS at the child-bearing period were income (β=1.51) and life events (β=-6.13), while that at the period of families with adolescents were economic income (β=1.81) and age (β=-0.65);that at the period of empty nest were economic income (β=-3.64) and age (β=-0.65);and that at the re-tirement or senior years were unhealthy living habit (β=-15.06),age (β=-0.56) and income (β=3.06). The influencing factors on MCS at the child-bearing period was medical insurance (β=5.86),while that at the period of families with adolescents were medical insurance (β=6.28),education (β=2.32),life events (β=-4.68) and occupation (β=-5.53);that at the period of the empty nest were age (β=-0.61) ,gender (β=-10.35) and chronic disease (β=-8.35);that at the retirement or senior years were age (β=-0.27) , economic income (β=2.55) and unhealthy living habit (β=-6.95) . Conclusion The influencing factors of QOL for different family cycle residents are not conformity with each other. It suggested that in order to im-prove the QOL of residents, the community health service including health education and health promotion should be based on different family life cycle.

OBJECTIVETo explore the effect of Se-riched soybean peptide (SSP) on antioxidant function in rats of fatty liver caused by high-fat diet.

METHODSForty Wistar rats were divided into 4 groups randomly and fed with standard diet and water (NC), high-fat diet and water (HC), high-fat diet and SSP (0.1 g/d) (SeH), standard diet and SSP (0.1 g/d) (SeN) respectively. After 10 weeks, the rats were killed to investigate the pimelosis level in liver tissues by Sudan III staining and the expression of hepatic GRP78 by immunohistochemical analysis. We also analyzed the changes of liver function, blood lipid, the glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in livers and serum.

RESULTSThe pimelosis level, total cholesterol (TC), triglyceride (TG), MDA contents and the expression of GRP78 in HC group were significantly higher than those in NC, SeN, SeH groups. The activities of GSH-Px and SOD in liver and serum were markedly up-regulated in SeH (P < 0.01). There was no significant difference between NC and SeN groups.

CONCLUSIONSSP can improve liver cell injury and the antioxidant functions in rats with fatty liver effectively and decrease the expression of GRP78 in liver.

The efficacy of Chinese herbal formula in treating depression has been proved in many studies. In this study, six different Kaixin San formulas were compared to investigate their effects on central monoamine neurotransmitters of chronic stress rats and against depression based on their different components in plasma, in order to discuss the efficacy-comparability relationship and the possible efficacy mechanism. The classic isolation method and the chronic unpredictable mild stress (CUMS) depression model were combined to investigate the changes in contents in hippocampus and monoamine neurotransmitters (NE, DA, 5-HT) and the components of some formulas in plasma with HPLC and UPLC-Q-TOF-MSE methods. As a result, Dingzhi Xiaowan recorded in Essential Recipes for Emergent Use Worth A Thousand significantly increased the behavioral scores, NE and 5-HT contents in hippocampus and NE, DA and 5-HT contents in cortex, with the best anti-depressant effect. Dingzhi Xiaowan recorded in Complete Records of Ancient and Modern Medical Works showed a notable increase in sucrose preference and open field score in model rats, NE content in hippocampus and NE, DA and 5-HT contents in cortex, with a certain anti anti-depressant effect. Kaixin San recorded in Ishinpo showed remarkable rise in weight of model rats. NE content in hippocampus and DA content in cortex. Puxin Decoction recorded in A Supplement to Recipes Worth A Thousand Gold showed 5-HT content in hippocampus and DA content in cortex. Kaixin San recorded in Yimenfang only showed DA content in cortex. Kaixin Wan recorded in Essential Recipes for Emergent Use Worth A Thousand did not mention the antidepressant effect. According to the results, the formulas' different anti-depressant effects may be related to the different plasma components.

OBJECTIVETo investigate the effect of Compound Qingqin Liquid (CQL) on the expression level of angiotensin II (Ang II) and COX-2 mRNA transcription and protein expression in the renal tissue of rats with uric acid nephropathy.

METHODSSD rats were randomly divided into the blank control group, the model group, the positive drug group, the high, moderate, and low dose CQL group according to number randomization principle. The model was established by gastrogavage of adenine, accompanied with yeast feeding. Distilled water was given by gastrogavage to rats in the blank control group and the model group. Allopurinol at the daily dose of 9.33 mg/kg was given by gastrogavage to rats of the positive control group. CQL at the daily dose of 3.77 g/kg, 1.89 g/kg, and 0.09 g/kg was respectively given by gastrogavage to rats in the high, moderate, and low dose CQL groups. All treatment lasted for 6 weeks. Rats were randomly divided at week 4 (3 in the blank control group, and 6 in the rest groups), and the rest rats were killed at week 6. The renal tissue was extracted. The expression level of Ang II and COX-2 mRNA transcription were detected by RT-PCR. The expression level of Ang II was detected by ELISA. The expression level of COX-2 protein was detected by Western blot and immunohistochemical assay.

RESULTSCompared with the blank control group, except the mRNA expression of Ang II at week 4, the mRNA and protein expression of Ang II and COX-2 obviously increased at week 4 and 6 in the model group (P < 0.01, P < 0.05). The COX-2 protein expression at week 4 was obviously lower in the high and moderate dose CQL groups than in the model group and the low dose CQL group (P < 0.05); the average integral of optical density value was obviously lower in the positive control group than in the model group. Except the mRNA expression of Ang II in the high dose CQL group at week 6, the mRNA and protein expression of Ang II obviously decreased in the positive control group and each dose CQL group (P < 0.01, P < 0.05). Of them, the effects were better in the high and moderate dose CQL groups than in the positive control group and the low dose CQL group (P < 0.05, P < 0.01). Besides, the mRNA expression of COX-2, the average integral of optical density value were obviously lower in the positive control group and each dose CQL group than in the model group (P < 0.05). The protein expression of COX-2 was obviously lower in the high and moderate dose CQL groups than in the model group (P < 0.05). Of them, the mRNA expression of COX-2 was better in the moderate dose CQL group than in the positive control group (P < 0.05); the protein expression of COX-2 was better in the high dose CQL group than in the low dose CQL group (P < 0.05).

CONCLUSIONCQL was capable of lowering the expression level of Ang II, COX-2 mRNA transcription and protein expression, thus suppressing the inflammatory pathological injury of the renal tissue.

OBJECTIVEThe objective of this study is to investigate the influence of zirconia content which is 0-30.0% weight percentage of matrix on translucency of zirconia-toughened alumina glass-infiltrated ceramics.

METHODSSeven groups were divided according to different weight percentage of zirconia (0, 2.5%, 5.0%, 7.5%, 10.0%, 20.0% and 30.0%). After sintering, infiltrating and polishing, spectral transmittance was determined with spectrophotometer under D65 standard source. Contrast ratio was also tested by whiteness colorimeter.

RESULTSWith mass fraction of zirconia increasing from 0 to 30.0%, spectral transmittance reduced from 0.406% to 0.058%, while contrast ratio value increased from 0.849 +/- 0.005 to 1.015 +/- 0.006. When zirconia content was 10.0%, contrast ratio was 0.990 +/- 0.008. When it was more than 10.0%, transmission rate of the downward trend and contrast ratio of the rising trend became flat.

CONCLUSIONZirconia content has a direct impact on translucency of zirconia-toughened alumina glass-infiltrated ceramic, which is essentially opaque when zirconia content is 10.0%. When mass fraction of zirconia is more than 10.0%, the influence of zirconia content is reduced.
