Objective To know the primary effect of nutrition intervention in farmers. Methods The questionnaires were used to do baseline and evaluation survey. The intervention ways were used in trial group, including holding lectures, posting posters, sending out healthy material, quizzes with prizes, recommending salts low in sodium to each family, training to make healthy food by the chef; but there were no measures in control group. Results There were statistical significance in healthy awareness of nutrition, exercises and chronic diseases between two groups after intervention; However, the average intake amounts of vegetables did not reach the recommendation of diet guidelines; After intervention, the intake frequency of vegetables and fruits had statistical significance between before and after intervention in trial group, and also had statistical significance in two groups. Conclusion The awareness of healthy knowledge and attitudes has been obvious improvement, but the diets and life styles of farmers have no obvious change. The diet structure and behavior of farmers have been increasingly rational but not enough. The farmers have started to increase the intake times of vegetables and fruits and built up the conception of eating more vegetables and fruits.

BACKGROUND:Corneal stromal fibroblasts have been shown to express interleukin-8 in the stimulation of lipopolysaccharide. Different reactions of fibroblasts to lipoprotein or other inflammatory mediators may constitute different characteristics of different tissues in the inflammatory response. OBJECTIVE:To observe the inhibitory effect of IKK-2 receptor blocker TPCA-1 on human corneal stromal fibroblasts to secrete inflammatory cytokines, chemokines and cel adhesion molecules under the stimulation of lipopolysaccharide and its signal transduction pathway, to compare with dexamethasone, and to explore alternative or synergistic effects after their combination. METHODS:This study measured the secretion of interleukin-1, tumor necrosis factor alpha, interleukin-6, and interleukin-8 from cultured human corneal stromal fibroblasts under the action of basic state and lipopolysaccharide, and their changes after the intervention with IKK-2 receptor blocker TPCA-1 and dexamethasone. We also detected expression level of intercelular adhesion molecule-1 and interleukin-6 in cel surface, and verified the changes in expression levels of intercelular adhesion molecule-1, interleukin-6, and interleukin-8 from mRNA level, as wel as examined the expression of nuclear factor kappa B under above conditions.

Objective To study the effect of Konjac polysaccharide (KP) on motilin (MOT) and somatostatin (SS) of gastrointestinal tissue in mice. Methods The mice were divided into four groups randomly. Normal control group (NC) was given normal feed. High, middle, low dose KP treated groups (KPH,KPM,KPL)were given KP 0.8, 0.4, 0.2g per 100g normal feed. The level of motilin and somatostatin of gastrointestinal. tissue was determined simultaneously by radioimmunassay, and blood glucose was determined by blood glucose analyzer after 20 d. Body weight, adipose tissue and wet weight of stool were also examined. Results The level of motilin of stools of KPH group was 8.26?0.53ng/g ,which increased compared with NC group.Somatostatin was 207.32?21.89 ng/g ,which decreased compared with NC group. The differences between two groups were significant (P

Mesenchymal stem cells(MSCs)have a unique role in immune regulation and focus to T-cells.In the mixed lymphocyte reactions,MSCs inhibit T-cells proliferation by cycle arrest,but they do not increase T-cell apoptosis and the suppress T-cell activation.In addition,MSCs can reduce CD8~+T cells and Thl cells,and simultaneously increase Th2 cells in the reaction system to suppress the inflammatory response,which may play a therapeutic effect on the T-cells mediated autoimmune diseases.

Objective:To explore the effect of fortified human milk feeding on growth and complica-tions of infants with extremely and very low birth weight (ELBW/VLBW)during hospital stay by a pro-spective,random and controlled study.Methods:In the study,1 22 ELBW/VLBW infants were enrolled and divided into two groups.The infants fed with human breast milk,combined with human milk fortifi-cation (HMF)during hospital stay were named HMF group (n=62),and those fed exclusively with pre-mature formula were named premature formula feeding group (PF group,n=60 ).The data of the in-fants’growth (the velocity of increase on the weight,length,head circumference and upper arm circum-ference),the time of rebounding to birth weight,the time of needing intravenous nutrition,the time of hospitalizing,the proportion of extrauterine growth retardation (EUGR)during hospital stay,the level of hemoglobin,bone metabolism and incidence of complications were compared between the two groups. Results:Among the 1 22 infants included,(1 )the length increment in HMF group was higher than PF group [(0.89 ±0.23)cm/week vs.(0.79 ±0.34)cm/week,P=0.04];there were no significant differences in the weight gain,head circumference increment and upper arm circumference increment (P>0.05);(2)the age of rebounding to birth weight [(1 0.1 3 ±4.03)d vs.(8.03 ±3.28)d,P=0.002]and the duration of intravenous nutrition [(1 6.77 ±6.63)d vs.(1 4.23 ±4.1 5)d,P=0.01 ] in HMF group were longer than that in PF group,there were no significant differences between the two groups in the hospital stay and age achieved feeding;(3 )there were no significant differences between the two groups in the incidence rate of EUGR during hospital stay (P>0.05);(4)the level of calcium at birth in HMF group was lower than that in PF group [(2.1 9 ±0.22)mmol/L vs.(2.32 ±0.27) mmol/L,P=0.005 ],and the level of alkaline phosphatase (AKP)in HMF group at discharge was higher than in PF group [(363.98 ±1 22.49)mmol/L vs.(299.73 ±1 1 7.39)mmol/L,P=0.004];(5)the incidence of the feeding intolerance (6.5% vs.1 8.3%,P=0.04)and sepsis (4.8% vs. 1 6.7%,P=0.03)in HMF group were less than in PF group,there were no significant differences be-tween the two groups on the morbidity of necrotizing enterocditis,retinopathy of prematurity (ROP),and bronchopulmonary dysplasia (BPD)(P>0.05).Conclusion:HMF for premature infants may ensure the same growth pattern as those fed by premature formula,promote the calcium absorption,decrease the inci-dence of sepsis and feeding intolerance,and does not increase the incidence of necrotizing enterocolitis.

TLR4-MD-2 complex plays a key role in LPS recognition and its signal transduction. These steps are the vital elements of the host's defensive reaction. Studying the functional domain of TLR4 and MD-2 is very important to further understand the mechanism of LPS signal transduction. It was studied the interaction domain of TLR4 and MD-2 in living cells based on gene mutation, gene transfection and fluorescence resonance energy tramsfer(FRET) which is considered as one of the best methods used for intracellular protein-protein interaction study. CY-15P which was fused by CFP and YFP through 15 neutral amino acids was used as positive control, while co-expressed CFP and YFP proteins were used as negative control. The results showed that the ability of TLR4 binding to MD-2 decreased dramatically after the deletion of Glu~(24) ～ Met~(41) in N terminal of TLR4. Aggregation of TLR4 to LPS stimulation was observed, however, TLR4 without the Glu~(24)～ Met~(41) mutation did not aggregate. All these results indicated that TLR4 Glu~(24)～ Met~(41) might be the interaction domain of TLR4 binding to MD-2 and participate in the aggregation effect of TLR4 upon LPS stimulation.

Objective To analyze and determine the clinical, molecular pathology and genetic features of a Chinese family with dystrophinopathy. Methods Clinical data of the proband and his family members were collected. Immunohistochemistry staining was performed on muscular biopsy tissues with antimerosin, emerin and the N, C and central rod domains of dystrophin. Genomic DNA was extracted using standard procedures from the peripheral blood leukocytes. Multiplex ligation-dependent probe amplification (MLPA) was used to test Duchenne muscular dystrophy (DMD) gene to determine the ways and sites of genetic mutation, and analyze the relationships between genotype and phenotype. Results Patients from this family were clinically diagnosed as muscular dystrophy, and they presented serious manifestations although the immunohistochemistry analysis for the proband exhibited partial loss of dystrophin staining, and positive expression with merosin and emerin. Further test with MLPA detected the loss of exons 45--54 in DMD gene in the proband, while his mother had heterozygositic loss in exons 45--54. Conclusions The losses of exons 45--54 in the proband are all derived from his mother, who carries genetic mutation with normal phenotype. He has been diagnosed as dystrophinopathy. At the same time, his partial loss of dystrophin is not parallel to the out-of-frame mutation of the gene and his severe clinical manifestations. Abnormal expression of dystrophin is the pathological basis for dystrophinopathy phenotype. Its clinical outcome depends not only on the degree of the protein expression, but also on the function of the sites where the DMD gene less occurs.
