Objective To evaluate the effect of lifestyle intervention on the indexes of patients with dyslipidemia.Methods CNKI,Wanfang Database,VIP,PubMed,Web of Science,EBSCO,EMbase,the Cochrane Library,Clinical Trials,MEDLINE were retrieved.The search terms included lifestyle intervention,lifestyle,diet,physical activity,dyslipidemia,hypercholesterolemia,lipid,low fat diet,plant sterols,low-glycemic index(GI)diets,mono-unsaturated fatty acids.Articles on randomized controlled trials(RCTs)to study the effect of lifestyle intervention on the indexes of patients with dyslipidemia were screened according to inclusion and exclusion criteria.Meta-analyses were conducted by using RevMan 5.3 software after extracting data.Results 19 articles were internalized,including 2 294 patients(intervention group,n=1,170)and(control group,n =1,124).According to the results of intervention group versus control group,total cholesterol of weighted mean difference(WMD)was (-0.61,95 ％CI.-0.84～-0.38,P＜0.01),triglyceride of WMD was(-0.28,95 ％ CI:-0.42～ 0.15),P＜0.01),low-density lipoprotein cholesterol of WMD was (-0.45,95 ％ CI:-0.72 ～ 0.18,P ＜0.01),(all P＜0.01),with significantly lower WMD in intervention group than in control group.The high-density lipoprotein cholesterol of WMD was (-0.05,95 ％ CI:-0.22 ～ 0.12,P =0.59),the difference was not significant.Conclusions Lifestyle intervention improves serum levels of total cholesterol,triglyceride and low-density lipoprotein cholesterol for dyslipidemia patients,but its effect on high-density lipoprotein cholesterol is not significant.

Quantitative calibration strategy as an essential issue in laser ablation ICP-MS plays an important role for the guarantee of analytical accuracy.In this study, uncertainties of reference values in current available glass certified reference materials (NIST, MPI-DING and USGS) as well as the matrix effect among them were systematically evaluated.The results illustrated that NIST610 was better than other reference materials from aspect of reference value uncertainty.The matrix effect among NIST, MPI-DING and USGS reference materials was insignificant under our experimental conditions.A quantification strategy based on two reference materials (NIST610 and StHs6/80-G) and normalization to 100% (w/w) was proposed to avoid the insufficiency of single reference material strategy, which suffered the very low content and large uncertainty for some elements.The comparision of ML3B-G results obtained from three quantification strategies (single reference material NIST610, single reference material StHs6/80-G and two refterence materials) illustrated that the proposed strategy improved the analytical accuracy.Three reference materials (BCR-2G, CGSG-2 and KL-2G) were quantified with the proposed strategy, and almost all data matched well with reference value, meanwhile the data reported here could supplement the reference value database.

Stroke is the disease which caused by many risk factors.The relationship between insulin resistance(IR) and young adult stroke is one of the focuses now in the neurological field.IR refered to the series of pathological and physiological changes,it happens when the response of the target tissue organ to insulin is depressing or losing.There are many ways of detection of IR,the insulin sensitivity index(ISI) is one of the most satisfied indexes to reflect the sensitivity to insulin.IR could cause a series of pathological and physiological changes,which caused hyperinsulinemia,hyperglycemia,hyperpiesia,blood-fat derangement,fibrinolytic system anomaly,blood vessel endothelium change,artherosclerosis,et al,maybe in ways of many metabolic risk factors.Atherosclerosis is the main etiopathogenisis factor in young adult stroke,as a conclusion,IR is also existed in young adult stroke.But,does IR exist in all types of young adult stroke? What is the mechanism? Is the level of IR related with the pathogenetic condition and prognosis? These questions are still not clear at present,and the study on the relationship between IR and young adult stroke is important to prevent young adult stroke.

ObjectiveTo investigate the effect of immunoglobulin G (IgG) extravasated from blood circulation on the expression of toll-like receptor 4 (TLR4) induced by peripheral lipopolysaccharide (LPS) in rat brain. Methods The rats were divided into four groups in random, 5 rats in each. Group one received LPS 100μg/kg by intraperitoneal administration, normal saline was given by intravenous injection 6 hours later; group two was injected with adrenalin (AD) 15μg/kg intravenously; group three was treated with LPS intraperitoneally, AD was injected 6 hours later; group four was injected normal saline intravenously as control. For all groups, the animals were sacrificed 30 min after the last injection, and the brains were taken for investigation of the TLR4 expressions by immunofluorescence staining and RT-PCR. Result Immunofluorescence staining showed that IgG immunoreactive product was patch-like, distributed in the brain parenchyma in all the animals that received AD. In the LPS+normal saline group, IgG was found merely around the blood vessels. Meanwhile, in LPS+AD animals, TLR4 immunoreactive product coexisted with microglia marker Iba-1 within the IgG extravasated area. The double-labeled cells dispersed in the brain parenchyma and near to the cerebral vessels. In the LPS+saline group, TLR4 positive cells were endothelial-like. RT-PCR results indicated that the expression level of TLR4 in the LPS+AD group were significantly higher than that in the LPS+saline group or AD group or the saline control (P<0.01). Conclusion Extravasated circulating IgG may enhance the TLR4 expression in the rat brain induced by peripheral LPS.

Objective:To reveal the dynamic characteristics of the intracellular complement mRNA from mouse macrophage ANA-1 treated with LPS or IL-4. Methods:The polarization models of macrophage ANA-1 were established by treating with LPS(1μg/ml) and IL-4(20 ng/ml),respectively. After treating at 3,8,12 and 24 h,the total RNA were abstracted by Trizol lysis methods . The macrophage polarization were estimated by the expression of IL-1β, CCL2 and Arg-1 mRNA detected by Real-time fluorescent quantitative PCR. The intracellular complement C1q, C3, CfB and CRIg mRNA were quantitatively analyzed. Results: The mouse macrophage ANA-1 cells treated with LPS was polarized to M1 since the levels of IL-1β and CCL2 mRNA were up-regulated significantly,in which their 2-△△Ct value were up to 297. 0±31. 0 and 19. 9±3. 3 respectively at 12 h. On the other hand,the ANA-1 cells treated with IL-4 was polarized to M2 because the level of Arg-1 mRNA was obviously higher( the 2-△△Ct value of Arg-1 mRNA was up to 27.3±9.1 at 24 h)(P<0.05).The intracellular complement C1q,C3,CfB and CRIg mRNAs all were up-regulated in different polarized macrophages. The intracellular C1q and C3 mRNA in polarized M2 were significantly higher,in which the peak value of C1q and C3 were to 94. 9±12. 9 and 11. 3±2. 4 at 12 h,respectively(P<0. 05). Reversely,the CfB mRNA in polarized M1 increased obviously,in which its 2-△△Ct was to 61. 4±6. 2 at 12 h. In addition,the CRIg mRNA in both groups was only up-regulated at 24 h,in which the 2-△△Ct value was 6. 5±1. 8 in M1 and 10. 8±3. 2 in M2(P<0. 05). Conclusion: The macrophage ANA-1 cell polarization models were successfully established by treated with LPS or IL-4. The intracellular complement C1q,C3 and CRIg mRNA in polarized M2 were transcripted more than in M1. But the intracellular CfB mRNA in polarized M1 was up-regulated significantly. These results suggested that the dynamic characteristic of complement components in different polarized macrophage would be correlated with its fun-tions.

0.05). It was revealed by correlation analysis that p-AMY level was negative correlated with that of fasting serum glucose (r=-0.127 6), 2h-glucose (r=-0.096 4) and GSP (r=-0.109 4), implying the hyper-glucose might increase pancreas fibrosis and lead to decreased secretion of p-AMY. Conclusion Changes of serum digestive enzymes are correlated with the progress of diabetes mellitus and hypertension, may reflect the pancreatic function, and should be much concerned.

Objective To investigate the effects of antisense p21 oligodeoxynucleotide (p21 ASODN) on the expression of p21 protein and extracellular matrix in cultured human glomerular mesangial cells (HGMC) under high glucose medium. Methods HGMCs were transfected with 50 nmol/L or 100 nmol/L p21 ASODN or scrambled control oligodeoxynucleotide (SCODN) using lipofectamine 2000. After incubation under normal (5.5 mmol/L) or high (30 mmol/L) glucose media and different times, HGMCs lysates were collected and the expression of p21, fibronectin and laminin was examined by Western blot. The secretion of fibronectin and laminin by HGMCs in supernatants of culture media was also detected with EOSA. Results High glucose media significantly stimulated the expression of p21, increased the syntheses and secretion of fibronectin and laminin in cultured HGMCs in a time-dependent manner. Transfection of HGMCs with p21 ASODN not only decreased p21 protein level caused by high glucose media, but also attenuated the expression and secretion of fibronectin and laminin in supematants of HGMCs lysates and culture media. Meanwhile, SCODN had no significant effects on the expression of p21, fibronectin and laminin. Conclusions High glucose promotes the expression of p21 , fibronectin and laminin in cultured HGMCs. Transfection of HGMCs with p21 ASODN can decrease p21 protein level caused by high glucose media, and attenuate the expression of fibronectin and laminin in supematants of HGMCs lysates and culture media. Modulation of p21 expression in HGMCs may work as an effective way to mitigate the progression of diabetic nephropathy.

To programming one Child's Behavior Problems Computer Screening System (CBPCSS), a series of software for analyzing child behavior individual and group sample. According to the world-famous American ACHENBACH child's behavior checklist, to ensure the screening quality and compatibility of cultures, we revised and standardized the norms of different ages in primary schools and nursery schools in various cities based on the principle of cluster stratified sampling. Then we designed CBPCSS carefully. The system can reliably and rapidly screen an individual child behavior and output the behavior factor curve (appearing in front of the profile). With CBPCSS we can observe the child behavior clearly. It takes twenty times shorter than that of manual screening. On the other hand, CBPCSS has a function of group analysis. The clinical practice proved that CBPCSS could substitute for manual screening completely. It is a powerful tool for social, scientific and pediatric medical workers.
