Objective To compare the effects of different prone and supine position duration within 24-hour period on mini-pig acute lung injury (ALI)models. Methods Fifteen female mini-pigs,mean weight (30.2±3.2) kg, length (76.5±5.9) cm were anesthetized and ventilated. Hydrochloric acid (pH 1.0)was aspirated intratracheally to create ALI model. Mini-pigs were assigned randomly into three groups: p rone 8 h group, prone 8h then supine 16 h; 16 h group, prone 16 h then supine 8 h; 24 h group, prone 24 h continuously. Min-pigs were euthanasia at the end of the experiment to take out the lung, examine the tissue change and calculate the wet to dry weight ratio of lung (W/D). Sample was cut into slices and carried on hematoxylin and eosin (HE) stain which was intended to calculate injury score by semi ration score criteria. Results W/D, and injury score were lower in 16 h group and 24 h group than the 8 h group,whereas no significant differences among the three groups. Conclusions Prone position for 16 hours or longer could decrease oxygenation by decreasing inflammation in acute lung injury(ALI)animal models.

Objective To investigate the effects of peroxisome proliferator-activated receptor γ (PPARγ) agonist on serum adiponectin (ADP),urine microalbumin (mALB) and kidney pathology of obese mice,and discuss the significance of PPARγagonists preventing obesity-related glomerulopathy (ORG).Methods Sixteen male ob/ob mice and 8 male C57BL/6 mice which were 8 weeks old were selected in this study.Ob/ob mice were dividing into 2 groups according to body mass:obesity group (M group) and pioglitazone intervention group (T group) which were fed with high lipid chow.C57BL/6 mice were control group (C group) which were fed with ordinary chow for 12 weeks.Body mass,blood glucose,serum ADP,urine mALB were assayed in each group and compared.The morphological changes of kidney were observe by HE staining,glomerular diameters were measured and compared.Zonula occludens-1 (ZO-1) and Wilms tumor 1 (WT1) were positioned by immunohistochemistry,the level of ZO-1 expression in podocyte and podocyte number which was signed with WT1 in each group were evaluated and compared.And then the correlations between serum ADP,urine mALB,body mass,blood glucose,kidney mass,glomerular diameter,the level of ZO-1 expression,podocyte number were analyzed.Results The serum ADP of obese mice decreased (P ＜ 0.05),and the urine mALB increased (P ＜ 0.05),when compared with that of control group,and there was a negative correlation between ADP and mALB (r =-0.538,P ＜ 0.01).Renal pathology showed glomerular hypertrophy,in part associated with focal segmental glomerulosclerosis (FSGS),the expression of ZO-1 in podocyte and podocyte number were lower than that of control group (P ＜ 0.05).After the intervention with pioglitazone,the urine mALB of obese mice reduced (P ＜ 0.01),and the serum ADP level of them was higher than that of obese mice without intervention (P ＜ 0.01).There was no glomerular hypertrophy and glomerulosclerosis in kidney of obese mice,the expression of ZO-1 in podocyte and podocyte number were higher tban that of obese mice without intervention (P ＜ 0.05).Conclusions The kidneys of obese mice have clinical and pathological changes indicating that obesity can lead to kidney damage.Pioglitazone can make the low serum ADP level of obese mice ameliorated,and make the urine mALB of them reduced.Renal pathological change significantly is alleviated,the expression of ZO-1 in podocyte and podocyte number are increased,indicating pioglitazone can improve renal injury related to obesity.

[ ABSTRACT ] AIM: To investigate the effect of advanced oxidation protein product-human serum albumin ( AOPP-HSA) at different concentrations on the permeability of human umbilical vein endothelial cell ( HUVEC) monolayer and the protective effect of NADPH oxidase inhibitor diphenyleneiodonium ( DPI ) against AOPP-HSA exposure. METHODS: Cultured HUVECs were exposed to 200 mg/L HSA (control) or AOPP-HSA (50, 100 and 200 mg/L).The permeability of the endothelial monolayer was assessed by measuring CMFDA-labeled THP-1 cells across the endothelial cells.The cultured HUVECs were treated with HSA (200 mg/L), AOPP-HSA (200 mg/L), or AOPP-HSA (200 mg/L)+DPI (100 μmol/L), and the activation of NADPH oxidase, endothelial monolayer permeability and cytoskeleton rear-rangement were evaluated.RESULTS: AOPP-HSA increased the permeability of the endothelial cell monolayer, and AOPP-HSA at 200 mg/L significantly increased the phosphorylation level of NADPH oxidase in the cells.Treatment with 100 μmol/L DPI obviously attenuated AOPP-HSA-induced NADPH oxidase activation, the increase in the permeability of the cell monolayer and the cytoskeleton rearrangement.CONCLUSION: AOPP-HSA increases the hyperpermeability of HUVEC monolayer via the phosphorylation of NADPH oxidase, and the NADPH oxidase inhibitor DPI reverses such effects.

Objective To evaluate the correlation between periodontitis and life style. Methods By using randomized cluster sampling method,2990 health check-up receivers were enrolled in this cross sectional survey from September 2007 to September 2008. The participants were requested to fill in a questionnaire to assess community periodontal index and synthesis grades. Multiple linear regression was used for data analysis. Results Gender (P = 0. 000) , age (P = 0. 000 ) , educational level ( P = 0. 001) , smoking (P = 0.011 ) and duration of teeth brush ( P = 0.026 ) were positively correlated with periodontitis. However, periodontitis showed no relationship with alcohol consumption, food intake, daily activity,frequency of teeth brush, periodontal bleeding. Conclusion Periodontitis is a condition with multiple risk factors. Improving life style may help to prevent general population from periodontitis.
