【摘 要】目的:探讨妊娠期糖尿病患者血清25-OH-D水平与胰岛素抵抗的相关性。方法:选择我院2016年1月~2017年7月在我院就诊的妊娠期糖尿病患者112例(GDM组)、同期正常妊娠孕妇110例(正常妊娠组),测定两组孕妇的空腹血清25-OH-D水平;同时测定两组孕妇空腹血糖(FPG)、血清胰岛素(FINS)、糖化血红蛋白(HbA1c)水平。并且根据公式计算出两组孕妇的HOMA-IR,以评价胰岛素抵抗程度。结果:(1)GDM组孕妇空腹血清25-OH-D为19.78±12.84 ng/mL,正常妊娠组孕妇为28.36±15.83 ng/mL。两组比较,差异有显著性(P<0.01)。(2)GDM组孕妇空腹血糖、血清胰岛素、HbA1c、HOMA-IR分别为5.68±1.67 mmol/L、13.48±5.00 mU/L、5.59%±0.47、3.64±2.13;正常妊娠組孕妇空腹血糖、血清胰岛素、HbA1c、HOMA-IR分别为4.73±1.07 mmol/L、9.51±5.36 mU/L、4.70%±0.57、2.27±1.48,两组分别比较,差异有显著性(P<0.01)。(3)GDM组孕妇空腹血清25-OH-D与HOMA-IR呈显著负相关(r=-0.404,P<0.01),与HbA1c呈显著负相关(r=-0.299,P=0.001)。正常妊娠组孕妇空腹血清25-OH-D与HOMA-IR呈负相关(r=-0.242,P=0.024<0.05),但相关性显著小于GDM组,与HbA1c无相关性(p=0.061>0.05)。结论:GDM组孕妇空腹血清25-OH-D水平明显降低,且与HOMA-IR呈显性负相关,提示GDM孕妇25-OH-D可能有助于减轻胰岛素抵抗。

[Abstract] Objective:To investigate the correlation between serum 25-OH-D level and insulin resistance in gestational diabetes patients.Methods We selected 112 gestational diabetes patients (GDM group)and 110 normal pregnant women at the same time (normal gestation group)from our hospital from January 2016 to July 2017 to determine fasting plasma 25- OH-D levels,fasting plasma glucose (FPG)levels,serum insulin levels (FINS),and glycosylated hemoglobin (HbA1c)levels in both groups.The HOMA-IR of two groups of pregnant women was calculated according to the formula to evaluate the degree of insulin resistance.Results (1)Fasting serum 25-OH-D level in GDM group was 19.78±12.84 ng/mL,and 28.36±15.83 ng/mL in normal pregnant women.There was a significant difference between the two groups (P<0.01).(2)Fasting blood glucose,serum insulin,HbA1c,HOMA-IR in the GDM group were 5.68±1.67 mmol/L,13.48±5.00 mU/L,5.59%±0.47,and 3.64±2.13,respectively.The levels of fasting blood glucose,serum insulin,HbA1c,HOMA-IR in normal pregnant women were 4.73±1.07 mmol/L,9.51±5.36 mU/L,4.70%±0.57,and 2.27±1.48,respectively.There was significant difference between the two groups.(P<0.01).(3)Fasting serum 25-OH-D was significantly negatively correlated with HOMA-IR in pregnant women with GDM (r=-0.404,P<0.01),and negatively correlated with HbA1c (r=-0.299,P=0.001).Fasting serum 25-OH-D was negatively correlated with HOMA-IR in normal pregnant women (r=-0.242,P=0.024<0.05),but the correlation was significantly lower than that in GDM group,and there was no correlation with HbA1c (p=0.061>0.05).).Conclusion The serum level of 25-OH-D in GDM group was significantly lower than that in HOMA-IR group,suggesting that 25-OH-D in GDM pregnant women may help to reduce insulin resistance.

维生素D近年来引起了人们的极大关注,因为维生素D缺乏症的全球流行与人类各种疾病的风险增加密切相关。同样,孕妇中的维生素D缺乏症也非常普遍,并且对母体和子代的终身健康具有重要意义。因此,在妊娠期间调节维生素D代谢的因素显得至关重要。近年来研究认为维生素D缺乏与GDM的发生有密切的关系,孕期补充维生素D能减轻胰岛素抵抗[1]。但目前国内外这方面的相关研究并不是完全一致,因此有必要继续探讨妊娠期糖尿病患者维生素D与胰岛素抵抗的相关性。该研究通过调查妊娠期糖尿病患者的血清25-OH-D的水平,进而分析25-OH-D与胰岛素抵抗之间的关系。现将结果报道如下。

1 资料与方法

1.1 一般资料

选择我院2016年1月—2017年7月在我院行产前检查的妊娠妇女,行75g无水葡萄糖OGTT试验,确诊妊娠期糖尿病112例(GDM组),并于同期筛选出糖耐量正常的孕妇110例作为对照(正常妊娠组)。……
