目的 分析2型糖尿病患者25-羟维生素D[25（OH）D]、糖化血红蛋白（HbA_1c）水平和外周血管病变（PVD）的相关性,为疾病的预防及早期诊断提供参考。方法 分析于南通市中西医结合医院进行治疗的2型糖尿病患者基本资料,检测其25（OH）D、HbA_1c以及肌酐、血钙等多项实验室指标,按照彩色多普勒超声检查结果将所有82例患者分为PVD阳性和阴性两组,通过样本检测分析PVD的影响因素。结果 经彩色多普勒超声诊断,82例T2DM中PVD阳性50例、阴性32例;PVD阳性患者病程、BMI、LDL-C、HbA_1c、高于阴性组,25（OH）D低于阴性组（P<0.05）;经Logistic回归分析,患者BMI、糖尿病病程、HbA1c以及LDL-C是PVD的影响因素（P<0.05）;82例患者中HbA_1c控制不佳62例,维生素D缺乏者PVD发生率71.43%,明显高于维生素D充足患者的45.00%（χ²=4.055,P=0.044）。结论 患者BMI、糖尿病病程、HbA_1c、LDL-C以及25（OH）D水平均会对PVD的发生起到重要影响作用,且对于HbA_1c控制不佳患者,出现维生素 D 缺乏时发生PVD的概率更高。

目的 探讨糖化血红蛋白(HbA1c)联合超敏C反应蛋白(hs-CRP)在筛查妊娠期糖尿病(GDM)的临床意义。方法 选择2013年9月1日—2014年8月31日在我院妇产科孕期产前检查及分娩的孕妇,根据糖耐量试验(OGTT)、HbA1c和hs-CRP检查,筛查出92例孕妇为GDM组,并随机抽取OGTT正常的健康孕妇90例为NGT组,25例健康孕龄女性为对照组,分析3组FPG、HbA1c、hs-CRP及OGTT结果。结果 GDM组OGTT、HbA1c、hs-CRP高于NGT组和对照组,差异有统计学意义(P<0.01),NGT组与对照组比较,HbA1c、hs-CRP浓度差异无统计学意义(P>0.05),但3组FPG差异无统计学意义(P>0.05),Pearson相关分析显示,HbA1c与hs-CRP呈正相关(r=0.79,P<0.01)。结论 GDM患者HbA1c、hs-CRP水平升高,HbA1c联合hs-CRP可能成为GDM筛查的良好指标。

Objective To evaluate the feasibility of combination of glycosylated hemoglobin A1c(HbA1c) and high-sensitivity CRP in screening of gestational diabetes mellitus(GDM). Methods According to glucose tolerance test(OGTT),HbA1c and hs-CRP during 24~28 pregnant weeks,92 women with GDM (GDM group) and 90 normal pregnant women (NGT group) were enrolled in this study with another 25 women of child-bearing age as the control group. The results of FBG, OGTT, HbA1c and hs-CRP among three groups were analyzed. Results OGTT, HbA1c and hs-CRP level in GDM group were higher than that in NGT group and control group (P<0.05), but there were no significant differences of the level of FPG of 3 groups(P>0.05).Compare with NGT group and control group, There were no significant differences of the level of HbA1c and hs-CRP(P>0.05). Pearson correlation analysis showed that HbA1c had significant association with hs-CRP(r=0.79, P<0.01). Conclusion HbA1c and hs-CRP level in GDM group were increased, HbA1c combined with hs-CRP could be of some value in screening of GDM.
