摘要:

近年来的研究发现,一些2型糖尿病(type 2 diabetes mellitus, T2DM)易感基因位点不仅与T2DM的发病风险有关,还会影响生活方式干预效果。为进一步探究T2DM易感基因单核苷酸多态性(single nucleotide polymorphism, SNP)位点对生活方式干预降低高危人群血糖应答效果的修饰作用,本课题组在德清农村社区开展了生活方式干预试验(2017年6月~12月,对干预组的研究对象进行强化生活方式干预,对照组仅接受常规健康知识宣教),并对研究对象进行SNP基因分型。研究发现,对于rs9502570,干预组中的CC+CT基因型人群的空腹血糖降低值显著高于TT基因型(P=0.031);干预组中CC+CT基因型人群的糖化血红蛋白值降低值为0.03%,TT基因型人群的糖化血红蛋白值升高了0.27% (P=0.012);CC+CT和TT基因型干预组和对照组的空腹血糖和糖化血红蛋白前后差值差之间也有统计学差异(均为P<0.001)。对于rs10811661,干预组中TT基因型人群的空腹血糖降低值显著高于CC+CT基因型(P=0.021);TT和CC+CT基因型干预组和对照组的空腹血糖前后差值差之间亦有统计学差异(P<0.001)。上述研究结果表明,rs9502570、rs10811661两个位点会在一定程度上修饰高危人群对T2DM生活方式干预降低血糖的应答效果,为今后进一步研制糖尿病高危人群个体化干预措施提供了客观依据。

Abstract:

In recent years, it has been demonstrated that some susceptible gene loci of type 2 diabetes mellitus (T2DM) are not only associated with the susceptibility risk of T2DM, but also the modifying effects of lifestyle interventions. To further explore the modifying effects of the single nucleotide polymorphism (SNP) on the onset of T2DM and the reduction of blood glucose in response to lifestyle interventions among the high-risk population, we performed a lifestyle intervention study in two Deqing rural communities during the period from June to December in 2017. The intensive lifestyle interventions were conducted among the study subjects of the intervention group while those in the control group only received conventional and general health education. All participants were genotyped by the MassARRY system. This study showed that for SNP rs9502570, fasting blood glucose showed a significantly greater reduction for individuals with CC + CT genotype than those with TT genotype (P=0.031). In the intervention group, the glycated hemoglobin A1C (HbA1C) decreased by 0.03% for those with CC+CT genotype, while HbA1C increased by 0.27% for those with TT genotype (P=0.012). The difference in the reduction of fasting blood glucose and HbA1c between the intervention and control groups was also statistically significant between individuals with TT and those with CC+CT genotype. For SNP rs10811661, the reduction of fasting blood glucose was significantly higher in people with TT genotype than those with CC + CT genotype (0.44 mmol/L vs 0.12 mmol/L, P=0.021). The difference in reduction of fasting blood glucose between the intervention group and control group was also statistically significant between TT and CC+CT genotype (P<0.001). In summary, the SNP genotypes of both rs9502570 and rs10811661 could modify the effects of lifestyle interventions on reducing fasting blood glucose and HbA1C among the high risk rural population for T2DM. The present study has provided supporting evidence for future development of individualized intervention measures for high-risk population of T2DM.
