those of control (P=0.0026 and 0.000 2 respectively). Further investigation for <40 yr and ≥40 yr subgroups showed that the differences between FDR and control were revealed in ≥40 yr subgroup in which plasma glucose (PG)、 INS and C-peptide (CP) levels were higher than those of control in addition to the similar changes of HOMA-B and FPG in the whole group comparison. These changes were mainly revealed in the 40~60 yr subgroup and in the BMI 22~27 subgroup. Conclusion The INS action and INS secretion in FDR non-diabetic individuals of type 2 diabetes pedigrees slightly decrease before appearance of IGT, especially in the members over 40 yr. 【Key words】 Diabetes mellitus, non-insulin-dependent; Pedigree; Insulin; C-peptide; First degree relatives
现已明确,2型糖尿病(DM)具有明显的家族聚集性〔1,2〕,DM 患者的家族成员 发生DM和糖耐量低减(IGT)的机会远高于非DM患者的家族成员。近年发现DM患者的子女及其一级亲属(一级亲)有胰岛素(INS)抵抗倾向〔3,4〕,但对2型DM发病初是否存在原发性β细胞功能减退仍有争论。国外少数研究提示2型DM患者的非DM而糖耐量减退的一级亲中存在INS分泌异常〔5〕。本研究对2型DM家系一级亲的血糖、INS、C-肽水平和INS作用及分泌的简易指标等8个参数水平比较旨在进一步明确中国人2型DM家系成员中是否存在这些变化,以便进一步认识2型DM的遗传机制。
