Metabolic syndrome is characterized by simultaneous occurrence of central obesity,hyperglycemia,dyslipidemia and hypertension,posing a serious health problem.Exercise plays a pivotal role in preventing and treating metabolic syndrome:it can(1)reduce weight and improve the fat deposit in organs;(2)improve insulin sensitivity and glucose transporter4 level and down-regulate blood glucose by promoting muscle glucose utilization;(3)improve the vascular endothelial function,increase the secretion of nitric oxide,decrease the secretion of endothelin,and finally reduce blood pressure;and(4)decrease blood levels of triglyceride and low density lipoprotein cholesterol,and increase the level of high density lipoprotein cholesterol.This paper is to review the effect of exercise on metabolic syndrome in an all around manner.

Objective To explore the lipopolysaccharide(LPS)-induced changes of heat shock protein A12B(HSPA12B)expression and its effect on the permeability of human umbilical vein endothelial cells(HUVECs).Methods The HUVECs cultured in vitro were divided into four groups: control group(without any treatment); LPS group(1 μg / m L LPS); LPS + p IRES2-EGFPHSPA12B-3Flag group(The HSPA12 B gene overexpression plasmid was transiently transfected into HUVECs and then LPS of 1 μg / m L was added); and LPS + p IRES2-EGFP-3Flag group(The negative control plasmid was transiently transfected into HUVECs and then LPS of 1 μg / m L was added).The transendothelial electrical resistance(TEER) of HUVECs was measured by MERSST × 01 Electrode.The expression of VE-cadherin was studied by flow cytometry.RT-PCR and Western blotting analysis were used to examine the expression changes of HSPA12 B mRNA and protein in HUVECs stimulated with LPS at various time points.Results It was showed that after stimulated with LPS,HSPA12 B mRNA and protein were gradually upregulated,and peaked at 12 h.HSPA12 B significantly increased the TEER value of HUVECs(P 0.001),and it could completely offset the decline of TEER value induced by LPS(P 0.001).Besides,HSPA12 B could cause upregulation of VE-cadherin expression.Conclusion HSPA12 B can reduce the permeability of vascular endothelial cells by up-regulating the expression of VE-cadherin,thus protecting the vascular endothelial barrier function of endothelial cells.
目的探讨脂多糖(LPS)诱导热休克蛋白A12B(HSPA12B)表达的变化及其对人脐静脉内皮细胞(HUVECs)通透性的影响。方法将体外培养的HUVECs分为4组:对照组(未经处理);LPS组(1 μg / m L LPS);LPS + p IRES2-EGFPHSPA12B-3Flag组(将hspa12b基因过表达质粒瞬时转染HUVECs，然后加入1 μg / m L的LPS);LPS + p IRES2-EGFP-3Flag组(将阴性对照质粒瞬时转染HUVECs，然后加入1 μg / m L的LPS)。采用MERSST × 01电极测定HUVECs的跨内皮电阻(TEER)。流式细胞术检测VE-cadherin的表达。采用RT-PCR和Western blotting方法检测LPS刺激HUVECs不同时间点hspa12b mRNA和蛋白的表达变化。结果LPS刺激后，hspa12b mRNA和蛋白水平逐渐上调，并在12 h时达到峰值，hspa12b显著提高了HUVECs的TEER值(P 0.001)，完全抵消了LPS诱导的TEER值下降(P 0.001)。hspa12b可引起VE-cadherin表达上调。结论hspa12b可通过上调VE-cadherin的表达来降低血管内皮细胞的通透性，从而保护内皮细胞的血管内皮屏障功能。

Objective To investigate the effect of activating α7 nicotinic acetylcholine receptor(α7n AchR) on cerebral cortical neurons injury induced by oxygen-glucose deprivation(OGD) and the possible mechanism.Methods Cerebral cortical neurons cultured for 7 d were randomly divided into three groups: control group,OGD group(Cells experienced a 12 h oxygen-glucose deprivation) and OGD group treated with PNU-282987(Cells experienced a 12 h oxygen-glucose deprivation with PNU-282987 pretreatment for 24 h).Cell viability was determined by CCK-8 assay,lactate dehydrogenase(LDH) was examined to reflect cell injury,apoptosis and reactive oxygen species(ROS) production were analyzed by flow cytometry,and expression of hemeoxygenase-1(HO-1) and hypoxia inducible factor-1α(HIF-1α) were detected by Western blotting analysis.Results OGD resulted in cell death,LDH increase,and cell apoptosis.Compared with the OGD group,PNU-282987 pretreated group had significantly increased cell survival(P 0.05),significantly decreased LDH level and ROS production(P 0.05),and significantly inhibited cell apoptosis(P 0.05).Meanwhile,HO-1 protein expression was significantly increased and HIF-1α protein expression was significantly reduced in PNU-282987 pretreated group compared with the OGD group(P 0.05).Conclusion Activation of α7n AchR can protect cerebral cortical neurons against OGD-induced injury,which may be related to the anti-oxidative stress.

Objective To observe the expression ofβ-arrestin2 in cardiac tissues of ovariectomzied(OVX)rats,and to explore the role ofβ-arrestin2 in estrogen-mediated cardiovascular protection in OVX rats.Methods OVX rats were evaluated by monitoring the serum levels of estrogen and the ratio of uterine weight to body weight.The cardiovascular function of rats was assessed by measuring the ratio of heart weight to body weight,blood pressure and heart rate after estrogen replacement treatment for 4weeks,Western blotting analysis was performed to detect the protein expression ofβ-arrestin1,β-arrestin2 and angiotensin receptor type 1(AT1R)in the cardiac tissues.Results Compared with rats in the sham group,the serum estrogen level and the ratio of uterine weight to body weight in OVX rats were decreased significantly(P0.05);meanwhile,the cardiovascular parameters including blood pressure,heart rate and the ratio of heart weight to body weight were significantly increased(P0.05)in OVX rats,and they were attenuated after treatment with estrogen replacement.Compared with the sham controls,the cardiac expression ofβ-arrestin2 was decreased significantly in OVX rats(P0.05),with up-regulated estrogen expression and unchanged expression ofβ-arrestin1 and AT1R.Conclusion β-Arrestin2 expression is decreased in the cardiac tissues of OVX rats,which can be increased by estrogen replacement therapy.
目的观察β-arrestin2在卵巢切除(OVX)大鼠心脏组织中的表达，探讨β-arrestin2在雌激素介导的OVX大鼠心血管保护中的作用。方法通过监测OVX大鼠血清雌激素水平和子宫重量与体重之比对其进行评价。雌激素替代治疗4周后，通过测量大鼠的心重与体重之比、血压和心率来评估大鼠的心血管功能，采用Western blotting分析检测心脏组织中β-arrestin1、β-arrestin2和血管紧张素受体1型(angiotensin receptor type 1, AT1R)蛋白的表达。结果与假手术组比较，OVX大鼠血清雌激素水平、子宫重量/体重比均显著降低(P0.05); OVX大鼠血压、心率、心重/体重比均显著升高(P0.05)，经雌激素替代治疗后均有所降低。与假对照组相比，OVX大鼠心脏β-arrestin2表达显著降低(P0.05)，雌激素表达上调，β-arrestin1和AT1R表达不变。结论OVX大鼠心脏组织中β-Arrestin2表达降低，雌激素替代治疗可使其表达升高。
