糖尿病视网膜病变(DR)是糖尿病(DM)最常见的严重并发症之一。长期慢性高血糖是DR发病的基础,微血管病变是最关键的病理改变,其发病机制与氧化应激,细胞凋亡、微血栓形成、细胞因子异常活化等多种因素有关。血红素氧合酶(HO)是一种广泛存在于各种组织中的血红素降解代谢的限速酶,其抗氧化应激、抗细胞增殖、抗凋亡、抑制血小板聚集等多种生物学效应得到了肯定并成为新的研究热点。本文就0H与SDR二者间的关系作一概述。 相似文献

血红素氧合酶是血红素降解的起始酶和限速酶。在糖尿病及糖尿病心血管并发症、糖尿病肾病和糖尿病视网膜病变的发展过程中多种组织细胞血红素氧合酶的表达水平发生了改变,而应用血红素氧合酶的抑制剂、诱导剂或基因干扰技术人为改变血红素氧合酶表达的水平可以加速或延缓该病程进展。提示血红素氧合酶做为糖尿病病情诊断和治疗的手段有一定临床应用前景。 相似文献

血脂异常与代谢综合征 总被引:25,自引:0,他引:25
流行病学研究发现 ,许多人往往同时存在高血压、中心性肥胖、血脂异常及高血糖 ,这些人发生心血管疾病的危险性很高。 1998年Reaven对此提出了“X综合征”的概念 ,以后又有学者冠以“胰岛素抵抗综合征”。 1999年WHO采用了“代谢综合征 (metabolicsyndrome)”的名称 ,定义为 :一个个体存在糖尿病或糖耐量减退 ,并同时具有下列两项以上组合 ,如高血压、血脂异常、中心型肥胖或微量蛋白尿。近年来 ,高尿酸血症、高纤维蛋白原血症、纤溶 /凝血异常等都被列入代谢综合征范畴。当前认为代谢综合征是多基因和多种环境因素综合作用所致的疾病。在… 相似文献

高血糖是糖尿病(diabetes mellitus,DM)最具特征性的临床表现,它可以增加活性氧(reactive oxygen species,ROS)的产生,引发氧化应激(oxidative stress,OS),从而导致DM时细胞生理功能失调.OS是指机体遭受各种有害刺激时,体内高活性分子如ROS和活性氮(RNS)产生过多,氧化程度超出氧化物的清除,氧化系统和抗氧化系统失衡,进而导致组织损伤等[1],由此可见,氧化系统在DM及其并发症发生过程中发挥着重要作用.而血红素氧合酶(heme oxygenase,HO)-1及其代谢产物是重要的抗氧化系统,目前大量研究证实HO-1在抗OS损伤中具有举足轻重的作用,可延缓DM及其并发症的发生.本文主要介绍近年来HO在DM及其并发症领域的研究进展.关键词:糖尿病;非胰岛素依赖型;血红素氧合酶-1;DM并发症分类号:R587.1 文献标识码:A文章编号:1671-038X(2014)03-0168-04 相似文献

The chronic intraperitoneal administration of the heme oxygenase inducer, hemin (15 mg/kg daily), for three weeks reduced blood pressure in adult spontaneously hypertensive rats (SHR) from 210.1±1.03 mmHg to 127±0.9 mmHg (n=10, P<0.01) but had no effect on age-matched normotensive Wistar-Kyoto or Sprague-Dawley strains. The antihypertensive effect of hemin was accompanied by reduced expression of aldosterone synthase messenger RNA and depleted levels of plasma aldosterone (675.7±121.6 pg/mL versus 365.7±37 pg/mL; n=4, P<0.05).Because aldosterone is known to stimulate phospholipase C (PLC), the effect of hemin on PLC was examined. Hemin abated PLC activity (29.6±1.5 nmol/min/mL versus 3.1±0.9 nmol/min/mL; n=5, P<0.01) and this was accompanied by depleted levels of intracellular calcium (551±46 nM versus 103.2±6.3 nM; n=4, P<0.01) in the aorta of SHR. In contrast, enhanced heme oxygenase activity and elevated cyclic GMP levels (17.74±0.08 pmol/mg versus 30.4±2.3 pmol/mg protein; n=6, P<0.01) were detected in hemin-treated SHR. Additionally, hemin therapy also suppressed inflammatory and oxidative insults by significantly reducing nuclear factor kappa B messenger RNA expression while enhancing the total antioxidant capacity (0.22±0.02 Trolox equivalent antioxidant capacity (TEA C)/mg protein versus 0.60±0.04 TEA C/mg protein; n=4, P<0.01).The concomitant depletion of aldosterone, PLC activity, intracellular calcium and the corresponding decline of inflammatory and oxidative insults may account for the antihypertensive effects of hemin. 相似文献

代谢综合征与阻塞性睡眠呼吸暂停低通气综合征独立相关 总被引:1,自引:0,他引:1
目的 探讨代谢综合征(Ms)与阻塞性睡眠呼吸暂停低通气综合征(OSAHS)可能存在的关系.方法 将82例经多导睡眠图(PSG)监测的肥胖者分为肥胖OSAHS组(55例)和肥胖非OSAHS组(27例),并选取30名正常体重者为正常对照组.测肥胖者的多导睡眠参数呼吸暂停低通气指数(AHI)、手指脉搏血氧饱和度(Spo2);所有受试者均测身高、体重、血压、腰围以及外周循环中代谢参数空腹血糖(FBG)、空腹胰岛素(FINS)、血清尿酸和血脂;以稳态模式评估胰岛素抵抗(HOMA-IR).比较肥胖OSHAS组和肥胖非OSAHS组间MS的患病率、各组间代谢指标的差异性,并分析肥胖OSHAS组各指标之间的相关性.结果 肥胖OSAHS组MS患病率明显高于肥胖非OSAHS组(69.09% us 37.04%,P<0.01).肥胖OSAHS组的收缩压、舒张压、FBG、HOMA-IR均高于肥胖非OSAHS组(P<0.05或P<0.01),而高密度脂蛋白胆固醇(HDL-C)则低于肥胖非OSAHS组(P<0.01).多元逐步回归分析表明舒张压与最低手指脉搏血氧饱和度(LSpo2)呈负相关,FINS、HOMA-IR与AHI呈正相关.结论 OSAHS与MS具有独立相关性,并可能是心脑血管疾病和其它全身性疾病的危险因素. 相似文献

代谢综合征(MS)是以中心性肥胖、高血压、脂质代谢异常、微量蛋白尿、葡萄糖耐量受损和(或)糖尿病等为特征的一组临床综合征,是导致糖尿病、心脑血管疾病的危险因素。1999年WHO将其正式命名为MS,并做了工作定义。2005年国际糖尿病联盟(IDF)对其提出了新的工作定义,进而达成全球共识。胰岛素抵抗是指机体对一定量胰岛素的生物学反应低于预计正常水平的一种现象,是导致MS发病的主要机制,其与MS各组分之间密切相关,但机制尚未完全阐明。本文就MS的定义及有关胰岛素抵抗在MS发生中的作用机制的研究的新进展做简要综述。 相似文献

AimsResults regarding the association between fish intake and risk of metabolic syndrome (MetS) are ambiguous. Therefore, this study aims to evaluate whether there is an association between fish consumption and risk of MetS.Data synthesisA comprehensive literature search was conducted of PubMed, Embase, ScienceDirect and Google Scholar up to August 2019. A random-effects model was used to pool the risk of MetS in the highest category of fish consumption compared with the lowest one. Subgroup analysis was conducted based on country of region, gender, dietary tool, MetS definition, energy adjustment and sample size. A dose–response of analysis of fish intake and risk of MetS was also conducted. Twelve studies with a total of 16 effect sizes (10 cross-sectional and six cohort) were included. An inverse association was observed between fish intake and risk of MetS in cohort (OR = 0.80, 95% CI: 0.66, 0.96; P = 0.017, I2 = 62.9%) but not cross-sectional studies (OR = 0.80, 95% CI: 0.70, 1.02; P = 0.085, I2 = 50.1%). Subgroup analysis suggested that the results were influenced by all the included variables but sample size. A significant non-linear association was observed between fish intake levels and risk of MetS (P-value for non-linearity = 0.010).ConclusionAn inverse association existed between fish intake and risk of MetS when combining data from prospective cohort studies. Further studies are needed to confirm such an effect. 相似文献

Aims
To determine the association between serum levels of vitamin B12 and metabolic syndrome (MetS) in a population of euthyroid adults.Materials and methods
We carried out an analytical cross-sectional study in euthyroid adults of both sexes, who attended the outpatient service of a private clinic in Lima-Peru during the 2012–2016 period. Participants were divided into tertiles (low, intermediate and high) according to their serum vitamin B12 values. MetS was defined when three or more metabolic criteria were met by the participants. We elaborated crude and adjusted Poisson regression models to evaluate the association between the serum vitamin B12 tertiles and the presence of MetS. The reported association measure was the prevalence ratio (PR) with their respective 95% confidence intervals (95%CI).Results
We analyzed 346 participants, the average age was 38.3?±?10.8 (SD) years, 117 (33.8%) were males, the serum vitamin B12 median was 364.1 (IQR: 274.2–473.4) pmol/L and the prevalence of MetS was 30.1% (n?=?104). In the crude Poisson regression model, we found an association between the serum vitamin B12 tertiles and the presence of MetS, with marginal significance. The association gained statistical significance in the adjusted model by potential confounders; and compared with the low serum vitamin B12 tertile, the prevalence of MetS was 36% lower (aPR?=?0.64; 95%CI: 0.43–0.96) among the high tertile group.Conclusion
Euthyroid participants with elevated levels of serum vitamin B12 showed a lower prevalence of MetS compared to those who had low levels of this marker. 相似文献18.

探讨代谢综合征(MS)患者血清Apelin的变化.用ELISA法测定血清Apelin.MS组Apelin明显升高(P<0.01),2型糖尿病MS组Apelin明显高于糖调节受损MS组和超重或肥胖者[(475.8±37.3对451.5±54.3及430.3±52.1)ng/L,P<0.01].多元逐步回归分析显示,胰岛素抵抗、体重指数和总胆固醇是Apelin独立相关因素.MS多种代谢组分异常与Apelin升高密切相关,可能是胰岛素抵抗加重所致. 相似文献

目的探讨代谢综合征(MS)胰岛素抵抗(IR)及高胰岛素血症与血浆醛固酮水平的关系。方法101例原发性高血压(EH)、135例特发性醛固酮增多症(IHA)患者按是否伴MS各分为两个亚组进行比较。结果EH伴MS组血浆卧位醛固硐(ALD)水平、胰岛素曲线下面积(InsAUC)、HOMA-IR及IR所占百分率均显著高于非MS组;IHA伴MS组血浆卧位ALD水平、InsAUC、HOMA-IR及IR所占百分率均显著高于非MS组和EH组。相关分析显示,伴MS两亚组的卧位ALD水平均与InsAUC及HOMA-IR显著正相关。结论MS患者较高的血浆ALD水平与高胰岛素血症及IR显著正相关,在高血压和心血管并发症的发生中起到一定作用。 相似文献
