摘要
目的研究南宁市126名健康体检儿童载脂蛋白B(ApoB)基因Xba I位点各基因型的分布情况,探讨其多态性对儿童生长发育、营养状况、血脂代谢及肾功能的影响。方法应用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术检测126例健康体检儿童ApoB基因Xba I位点的基因型,计算体质指数(BMI),测定血清总蛋白(TP)、白蛋白(AIB)、球蛋白(GLO)、白蛋白/球蛋白(A/G)、脂蛋白a(LPa)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、非高密度脂蛋白胆固醇(non-HDL)、低密度脂蛋白胆固醇(LDL-C)、载脂蛋白A1、(ApoA1)、ApoB、ApoA1/B、尿素氮(BUN)、肌酐(Ccr)及尿酸(UA)。结果(1)Xba I位点各基因型的频率分别为X-/X-:92.06%(116/126),X+/X-:7.14%(9/126),X+/X+:0.79%(1/126);等位基因X-与X+的频率分别为95.63%和4.37%;(2)等位基因X+组血清TP、AIB、A/G和ApoA1/B显著低于X-组,而BMI、LPa、TC、TG、non-HDL、LDL-C、ApoB、BUN和Ccr明显高于X-组。结论ApoB基因Xba I位点多态性对儿童生长发育、营养状况、血脂代谢及肾功能有影响。
Objective To study the distribution characteristics of ApoB gene Xba I locus among healthy children in Nanning, and to probe the effect of polymorphism on children's growth, nutritional status, serum lipids metabolism and renal function. Methods Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) technique was used to analyze the Xba I genotypes of ApoB gene among 126 healthy children in Nanning, body mass indexes(BMI), serum levels of total protein(TP), albumin(AIB), globulin(GLO), A/G, lipoprotein a(LPa), total cholesterol (TC), triglyceride(TG), highdensity lipoprotein cholesterol (HDL-C), non-HDL, low-density lipoprotein cholesterol (LDL-C), ApoA1, ApoB, ApoA1/B , blood urea nitrogen(BUN), creatinine clearance rate(Ccr) and uric acid(UA) were detected. Results (1) The distribution of the Xba I genotypes were X -/X - : 92.06 % (116/126), X +/X- : 7.14 % (9/126), X +/X + : 0.79 % (1/126) ; and the allele frequencies were X - :92.06% (116/126), X + :7.94 % (10/126) ; (2)The serum levels of TP,AIB,A/G 和 ApoA1/B among X + children were lower than tho^e in X- children, while BMI. LPa,TC,TG, non-HDL. LDL-C,ApoB, BUN and Ccr of X + were higher than X - significantly. Conclusion The Xba I locus polymorphism of apolipoprotein B gene can affect children's growth, nutritional status, serum lipids metabolism and renal function.
