To investigate the effect of menopause on chemokine receptor CXCR2 expression on monocyte, 21 postmenopausal and 20 premenopausal women were enrolled in the present study. Fasting venous blood was collected, and plasma estrogen levels were determined with radio immunoassay. Monocytes were separated from peripheral blood with gelatin method. Protein expression of chemokine receptor was assayed with flow cytometry and mRNA concentration was measured with RT PCR. The results showed that the levels of plasma estrogen decreased, whereas protein and mRNA expression of chemokine receptor CXCR2 increased after menopause. The plasma estrogen levels were negatively correlated with chemokine receptor CXCR2 expression in monocytes. These data suggested that the changes in CXCR2 on monocytes might contribute to,at least partially,the increased risk of developing coronary heart disease associated with estrogen secretory changes.

Objective To evaluate the effect of ecoimmunonutrition on systemic inflammatory response in swine with acute necrotizing pancreatitis (ANP). Methods Swine model of ANP was induced by retrograde injection of 5% sodium taurocholate and trypsin into the pancreatic duct. 24h after the ANP models were established, eighteen swine were randomly divided into total parenteral nutrition (PN) group (n = 6), enteral nutrition (EN) group (n = 6), and ecoimmunonutrition (E1N) group (n = 6). Each of the three nutrition formulas was given to each group respectively for eight days. The level of plasma endotoxin and serum concentrations of TNF-α, IL-1β, IL-6 and IL-10 were measured before, 24 h after the induction of ANP and 1,2, 4, 8 d after nutrition support. Results 24 hours after the ANP models were established, the serum level of plasma endotoxin, TNF-α, IL-1β, IL-6 and IL-10, NF-κB activities in EIN group were ( 1.85 ± 0.18) EU/L,(461.59 ± 128.25 ) pg/ml, ( 185.49 ± 58.81 ) pg/ml, ( 354.26 ± 34.63 ) pg/ml, ( 110.32 s 25. 18 ) pg/ml,(51.06 ± 2.27 )%, respectively, which all were significantly higher than those before the ANP models were established, but there were no difference among three groups. Eight days after nutrition support, those levels in EIN group were (1.48 ±0.16 )EU/L, (30.11 ±9.12)pg/ml, (20.17 ±7.04)pg/ml, (36.42 ±7.24) pg/ml and ( 89.46 ± 13.54 ) pg/ml, (9.06 ± 0. 17 ) %, respectively, which all were significantly lower than those of TPN and EEN group ( P ＜ 0. 05 ). The ration of IL-10/IL-6 was 2.51 ± 0.42 in EIN group, and 2.28 ± 0. 19 before the ANP models were established. Conclusions EIN could attenuate endotoxemia, decrease NF-κB activities and serum concentrations of cytokines and maintained the balance of pro- and anti-inflammation.

Objective To evaluate the effect of ecoimmunonutrition on maintenance of the mucosal barrier function in pigs with severe acute pancreatitis(SAP).Methods Twenty pigs were injected with5% sodium taurocholate and trypsin into the pancreatic duct to establish SAP models.Twenty four hours later,18 suvival pigs were randomly given parenteral nutrition(PN group,n=6),elemental enteral nutrition(EEN group,n=6),or ecoimmunonutrition(EIN group,n=6)for 8 days.The serum amylase,endotoxin and intestinal permeability were determined on different times.All pigs were sacrificed 8days later,and their venous blood,mesenteric lymph nodes(MLN),liver,lung,spleen and pancreas specimens were cultured quantitatively and qualitatively with standard techniques.The morphology of small bowel was observed and pathological changes of the pancreas was analyzed.Results Serum amylase of all groups were obviously elevated,but there was no significant difference among them(P＞0.05).The plasma endotoxin and intestinal permeability were lower in EIN group[(1.50±0.18)EU/L and(42.8±20.0)×10-3 respeetively]compared to EEN group[(1.98 4±0.20)EU/L and(67.4±23.0)×10-3 respectively]and PN group[(3.96±0.40)EU/L and(197.2±47.4)×10-3.respectively](all P value＜0.05).The incidence and the magnitude of bacterial translocation in EIN group were lower than those in PN and EEN groups.However,the ileum mucosa thickness,villus height,crypt depth and the rate of the normal intestinal villi in EIN group were(398.27±52.93)μm,(269.72±41.66)μm,(681.98±58.33)μm and 79%,respectively,but in PN group were(218.32±35.81)μm,(145.76±23.34)μm,(376.20±48.23)μm and13%,respectively and in EEN group were(305.70±42.72)μm,(192.52±38.17)μm,(507.31±68.23)μm and 47%,respectively.Conclusions EIN can maintain the integrity of intestinal mucosal barrier and decreasing intestinal bacterial and endotoxin translocation in SAP pigs.

Objective To explore the clinical,laboratory,and pathologic manifestations of the interstitial lung disease(ILD)associated with primary Sj(o)gren's syndrome(pSS,pSS-ILD).Methods Clinical data of 15 patients with pSS-ILD admitted to our hospital from 2006 to 2008 were collected and the different features were compared with 18 patients with pSS without ILD.Eight patients with pSS-ILD were followed up and observed the changes of high-resolution computed tomography (HRCT).Results The age at onset was later in pSS-ILD[(57±11)years]than in pSS without ILD[(43±11)years](P<0.01).The initial symptoms in six of patients with pSS-ILD were cough,expectoration,chest distress or dyspnea upon exertion.The respiratory clinical manifestations,circulationsystem involvement and pulmonary artery hypertension (PAH) were more common in pSS-ILD than in pSS without ILD(P<0.01).Compared with patients with pSS without ILD,patients with pSS-ILD had significantly higher serum IgG level(P<0.01).The common findings of HRCT included reticular changes,irregular linear hyper-attenuating areas,and nodules.Pleural involvement was found in 8 patients,honeycomb change in 5 patients and PAH in 3 patients.After treated for 6 months of 8 patients,radiological findings improved in 4 patients,stable in 2 patients,and worse in 2 patients.The comlnon histological findings included focal fibrosis in alveolar wall and alveolus with and alveolar space inflammatory cell infiltration,interstitial inflammation with mulifocal lymphocyte infiltration.One patient had the pathological changes of nonspecific interstitial pneumonia(NSIP).Conclusion The age at onset of pSS-ILD is late and tends to produce respiratory symptoms and prone to have circulationsystem involvement such as PAH and elevated serum IgG level.Honeycomb change in HRCT can be seen in one third of patients and most patients can improve after treatment,however.NSIP can be observed in histopathologieal
