医学免费论文:超敏C-反应蛋白及脂联素与2型糖尿病大血管病变的相关性研究
[摘要]目的:分析2型糖尿病合并大血管病变与血清超敏C-反应蛋白及脂联素水平的相关性。方法:79例2型糖尿病患者,按有无大血管病变分为伴大血管病变组(A)40例,无大血管病变组(B组)39例。另选40例健康者作正常对照组(C组),均检测血清超敏C-反应蛋白,脂联素及空腹血糖、空腹胰岛素、血脂等指标。结果:A组血清超敏C-反应蛋白高于B组及C组(P<005),B组明显高于C组(P<005),A组脂联素水平明显低于B组及C组(均P<005),B组明显低于C组(P<005)。相关分析提示血清超敏C-反应蛋白与脂联素有相关性(P<005)。结论:超敏C-反应蛋白,脂联素对于2型糖尿病患者发生大血管病变的预测具有重要意义。

Association of ultrasensitive C-reactive protein and adiponectin with macrovascular complications in patients with type 2 diabetes mellitusBAI Hua,LIN Yang,WU Chun-fang (The Fourth People′s Hospital of Zhanjiang City,Zhanjiang524008,China)Abstract:ObjectiveTo explore the association of hypersensitivity C-reactive protein (hs-CRP) and adiponectin with macrovascular complications in patients with type 2 diabetes mellitus (DM)MethodThe 79 cases of type 2 diabetes mellitus were divided into two groups (40 cases with macrovascular process as group A and 39 cases without as group B),and 40 heathy subjects served as a control groupHs-CRP,adiponectin,fasting blood glucose (FBG),fasting insulin (FINS),serum lipid and other indicators were measuredResultsThe level of hs-CRP in group A was higher than that in group B and group C(P<005),and group B was significantly higher than that in group C (P<005)The level of adiponectin in group A was significantly lower than that in group B and C(P<005),and group B was lower than that in group C(P<005)Linear correlation analysis showed that there was association between the serum hs-CRP with adiponectin(P<005)ConclusionHs-CRP and adiponectin seem to be risk factors of type 2 diabetes and the macrovascular complication and plays an important role in risk prediction of type 2 DM patients with macrovascular complicationKey Words:Type 2 diabetes mellitus;Macrovascular complications;Hypersenditivity C-reactive protein;Adiponectin
2 型糖尿病(DM)是一种严重影响人类生命健康的疾病,其血管并发症是其死亡和致残的主要原因。近年来糖尿病炎症学说备受关注,认为DM是一种自然免疫和低底炎症性疾病。C-反应蛋白(CRP)是血管炎症反应的一个敏感指标。脂联素是一种由脂肪细胞合成、分泌的由244个氨基酸组成的脂肪特异蛋白,具有抗炎、抗动脉硬化的作用。我们分析了2型糖尿病合并大血管病变及无大血管病变与超敏CRP(hs-CRP)、脂联素的相关性,旨在探讨2型糖尿病与慢性炎症的关系医.学.全.在.线www.lindalemus.com。
1对象与方法
11对象:2型DM 79例,均为我院就诊患者,其中男49例,女30例,年龄55~75岁,均符合1999年WHO的2型糖尿病诊断标准,排除急慢性感染性疾病,免疫性疾病及肿瘤患者。DM伴大血管病变组(A组)40例,男23例,女17例,年龄(525±106)岁,其中冠状动脉硬化者15例,脑动脉硬化者11例,颈动脉硬化者10例,既患冠状动脉硬化又患脑动脉硬化者4例。2型DM无大血管病变组(B组)30例,男17例,女13例,年龄(502±125)岁。正常人群组(C组)30例,男14例,女16例,年龄(476±136)岁。各组在性别、年龄等方面差异无统计学意义(P<005),具有可比性。
12方法:所有研究对象均经全身体检及颈动脉和双下肢动脉彩色多普勒超声波和头颅CT检查。Hs-CRP采用北京利德曼生化技术有限公司产品。批内CV 03%,批间CV 21%。甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)与低密度脂蛋白胆固醇(LDL-C)、空腹血糖(FBG)均使用美国贝克曼CX5 PRO全自动生化分析仪测定,脂联素测定采用放射免疫法,试剂购于广州标佳科技有限公司,批内CV<512%,批间CV<725%。
13统计学方法:采用EXCEL2003统计数据,计量资料用(x±s)表示。两组间比较采用t检验,各组间比较采用方差分析。Hs-CRP为非正态分布,以中位数和四分位间距表示,转换为自然对数后呈正态分布。Hs-CRP、脂联素与各指标间的相关性采用简单相关分析,P<005有统计学意义。
