Metabolic syndrome (MS) refers to a complex disease, characterized by metabolic disorders. The prevalence of MS have a greater difference in different nations, regional, ethnic and nationals. The associations between gamma-glutamyltransferase, adipocytokines and MS have been given the most attention by researchers. But the accurate relations between them were not still explicit. Using laboratory study and field epidemiological survey, the blood pressure, gamma-glutamyltransferase, lipocalin2, blood-lipidant, glucose were measured in general health checkup among Korean minority and Han-Chinese in Yanbian. The study explored the associations of GGT, LCN2 with MS and multiple metabolic disorders in Korean and Han-Chinese, and the interaction between GGT and LCN2, which can provide basic information and blood samples to future investigation on the effects of genes and environment in various nationals, prospective studies and epidemiological studies. This research not only clarified the role of GGT and LCN2 in the incidence of MS and the differences of risk factors in different nationals, but also lay the foundation for future research on metabolic disease etiology and the etiology of other disease among different nationals.
代谢综合征是(MS)是以代谢紊乱为特征的复杂性疾病,不同国家、地区、种族、民族的患病率差别较大。谷氨酰基转肽酶(GGT)、脂肪细胞因子和代谢综合征(MS)的相关性研究日益被受关注,但它们之间的关系尚不明确。本课题采用现场流行病学和实验室研究方法,在延边独有的少数民族朝鲜族和汉族人群中通过体检方式测量血压等指标和检测血浆中GGT、脂肪细胞因子脂质转运蛋白2(LCN2)和血脂、血糖等MS有关的指标。分析比较朝鲜族和汉族人群中GGT、LCN2水平与MS及多代谢异常的相关性及GGT与LCN2在MS中的交互作用,并为下一步不同民族人群基因与环境的相互关系研究、前瞻性研究和移民流行病学研究提供基础资料和血液标本。这一研究将阐明不同民族GGT、LCN2在MS中的作用及不同各民族MS患病危险因子的差异,为进一步建立代谢疾病病因的研究和有民族差异的其他疾病的病因研究奠定基础。
本课题利用现况研究和实验室研究方法探讨通过朝鲜族和汉族的MS患病中GGT、LCN2的作用及交互作用结果显示,朝鲜人群和汉族人群中GGT、LCN2水平有差异,且MS组GGT、LCN2水平均高于对照组。在朝鲜族和汉族人群中未调整时LCN2第四分位数组MS患病危险分别是第一分位数组的1.476倍和2.013倍,调整年龄和性别后,朝鲜族人群是这种患病风险消失,汉族是仍存在;GGT第四分位数组MS患病危险分别是第一分位数组的2.415倍和2.493倍(调整年龄和性别)。在朝鲜族人群中,调整性别和年龄后LCN2第四分位组中心性肥胖、低HDL血症的患病风险分别是第一分位组的1.811倍和1.645倍。GGT第四分位组中心性肥胖、高血糖、高血压、高TG血症、低HDL血症的患病风险分别是第一分位组的3.539倍、5.324倍、3.408倍、19.286倍、4.288倍。在汉族人群中,调整性别和年龄后LCN2第四分位组中心性肥胖、高TG血症的患病风险分别是第一分位组的1.483倍和1.126倍,LCN2第三分位组低HDL血症的患病风险是第一分位组的1.538倍。GGT第四分位组中心性肥胖、高血糖、高血压、高TG血症、低HDL血症的患病风险分别是第一分位组的6.067倍、5.103倍、3.942倍、16.366倍、5.640倍。朝鲜族LCN2、GGT水平预测MS的临界值分别是24.69mmol/L和 32.50 U/L,在汉族中LCN2和GGT预测MS临界值分别为31.86mmol/L和36.50 U/L。本研究为探讨不同民族MS的预防提供科学依据。
