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.

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.

Objective To investigate the effects ofLiuwei-Dihuang Pills combined with Ginkgo Biloba Leaves Extract Tablets on diabetic complications in patients with type 2 diabetes mellitus (T2DM). Methods Seventy-eight patients with T2DM were randomized into a TCM treatment group and a conventional treatment group by random number table method, 39 in each group. The patients in the conventional treatment group were regularly using antihyperglycemic drugs or insulin. On the basis of conventional treatment group, the patients in the TCM treatment group were additionally treated withLiuwei-Dihuang Pills and Ginkgo Biloba Leaves Extract Tablets. Intima-media thickness (IMT) of internal carotid artery, vibration perception threshold (VPT) and diabetic retinopathy in both groups were detected before the treatment, 12 and 36 months after the treatment.Results The VPT in the left foot 12 months after the treatment in the TCM treatment group were significantly lower than that in the conventional treatment group (13.98 ±4.38 Vvs. 18.70 ±2.43 V;t=2.764, P=0.008). IMT of internal carotid artery (left: 0.81 ± 0.16 mmvs.0.70 ± 0.10 mm,t=3.120,P=0.003; right: 0.81 ± 0.17 mmvs. 0.73 ± 0.12 mm,t=2.286,P=0.026), VPT (left foot: 14.82 ± 6.45 Vvs. 20.63 ± 9.75 V,t=2.714, P=0.009; right foot: 16.73 ± 7.10 Vvs. 20.73 ± 10.35 V,t=2.001,P=0.048) and incidence of diabetic retinopathy (35.9%vs. 53.8%;χ2=5.804,P=0.016) 36 months after the treatment in the TCM treatment group were significantly lower than those in the conventional treatment group.ConclusionsLiuwei-Dihuang Pills combined with Ginkgo Biloba Leaves Extract Tablets can effectively reduce the progression of diabetic complications in patients with T2DM.

There were 50 cases using raltitrexed combined with concurrent radiotherapy as observation group. Others were treated with 5-Fu combined with concurrent radiotherapy as control group. The clinical therapeutic effect and survival situation of two groups were evaluated. Results After treatment, the total response rate of observation group (86.0%) was higher than control group (58.0%), the differences between the two groups was statistical difference(P<0.05).The one- and two-year survival rates in observation group were higher than control group (χ2 = 4.32, 7.954, P=0.038, 0.005<0.05).There was no significant difference between the two groups in incidence rate of acute esophagitis, acute bone marrow suppression and acute skin reaction. Conclusion The clinical therapy of raltitrexed plus radiotherapy in treatment of esophagus cancer is distinct, and improve the survival time and the quality of life of patients.

AIM: To investigate whether celecoxib,a cyclooxygenase-2(COX-2) inhibitor,potentiates the anti-leukemia activity of STI571 in K562 cells.METHODS: K562 cells were treated with STI571,celecoxib or combination of both at different concentrations in suspension culture.Cell proliferation was documented by MTT assay,and cell apoptosis was determined by flow cytometry and morphology.Meanwhile,RT-PCR was applied to analyze the probable mechanism underlying the effects of the drugs.RESULTS: The combination of STI571 and celecoxib dramatically suppressed the proliferation of K562 cells,in which 0.25 ?mol/L STI571 and 40.0 ?mol/L celecoxib enhanced the inhibiting rate to 76.1%?1.6%.Furthermore,the combining administration of drugs significantly promoted the apoptosis induced by STI571,which showed characteristic changes of morphologic features and increase in sub-G_1 cells.By using RT-PCR technique,the expression of COX-2 had no decline by single administration of celecoxib or STI571.However,a progressive down-regulation was caused by coadministration of two drugs.In contrast with COX-2,the expression of VEGF had no changes at any time.CONCLUSION: The administration of celecoxib alone only inhibits the proliferation of K562 cells.Combination treatment with STI571 and celecoxib promotes the apoptosis induced by STI571.

Objective To observe the protective effects of short-term continuous subcutaneous insulin infusion (CSⅡ) therapy on the peripheral blood circulating endothelial progenitor cells (EPCs) in patients with newly diagnosed type 2 diabetes mellitus (T2DM) and its antioxidation mechanism. Methods Forty T2DM patients (T2DM group) and 30 controls (control group) were involved in this study. Density gradient centrifugation was used to collect peripheral blood mononuelear cells. After 7 days' inducement and differentiation, FITC-UEA and DIL-acLDL double staining cells were identified to be differentiated EPCs by laser scanning conform microscope, and they were counted under inverted microscope. Serum levels of reactive oxygen species (ROS), malondialde-hyde (MDA), glutathione (GSH), superoxide dismutase (SOD) were examined. Results In T2DM group, the EPCs in peripheral blood were significantly reduced (46 ± 3 vs 23 ± 4, P< 0.01), BOS and MDA increased[(1125 ± 687) U/ml vs(2088 ± 765) U/ml, (4.58 ±3.03) μ mol/L vs (8.32 ± 4.15) μ mol/L, P < 0.01] , and GSH and SOD decreased [(263 ± 35) mg/L vs (206 ± 41) mg/L, (103 ± 7) U/ml vs (80 ± 15) U/ml, P < 0.05] . EPCs were negatively correlated with BOS and MDA (r = -0.7352,P < 0.01 ;r = -0.8454, P < 0.01) and was positively correlated with GSH and SOD (r =0.5435,P <0.05;r =0.6437,P <0.05). After short-term CSⅡ therapy, EPCs, GSH, and SOD in patients with T2DM significantly increased (P < 0.05),but BOS and MDA significantly decreased (P <0.05). Conclusion Short-term CSⅡ therapy can significantly reduce oxidative stress in patients with T2DM, promote the restoration of EPCs, and then prevent vascular disease.
