摘要: 目的 探讨维生素D受体TaqI基因多态性与儿童肾病综合征激素治疗敏感性的关系.方法 研究对象为2015年5月至2016年11月收住昆明医科大学第一附属医院儿科的70例肾病综合症患儿, 维生素D受体TaqI基因多态性检测方法为PCR扩增产物酶切后琼脂糖凝胶电泳检测.结果 在70例肾病综合征患儿中, 其中激素敏感型42例, 激素耐药型28例.在42例激素敏感型肾病综合症患儿中, TT基因型频率57.1%, 在28例激素耐药型肾病综合症患儿中, TT基因型频率57.1%, (P=1.000) .在42例激素敏感型肾病综合症患儿中, Tt基因型频率26.2%, 在28例激素耐药型肾病综合症患儿中, Tt基因型频率25.0%, (P=0.911) .在42例激素敏感型肾病综合症患儿中, tt基因型频率16.7%, 在28例激素耐药型肾病综合症患儿中, tt基因型频率17.9%, (P=0.897) .在42例激素敏感型肾病综合症患儿中, T基因频率70.2%, t基因频率29.8%, 在28例激素耐药型肾病综合症患儿中, T基因频率69.6%, t基因频率30.4%, (P=0.096) .等位基因型频率与等位基因频率在激素敏感型与激素耐药型之间无统计学意义.结论 维生素D受体TaqI基因多态性不能作为肾病综合症的标志基因, 也不能预测肾病综合症患儿对激素治疗的反应性.不能作为激素耐药型肾病综合征的标志基因.

Abstract: Objective To determine the frequency of gene and the association of VDR gene polymorphismswith nephrotic syndrome (NS) and steroid responsiveness in Yun Nan children, so as to guide the use of hormone and immune inhibitor in this disease.Methods The subjects of the study were the 70 cases of children with nephrotic syndrome in pediatrics in the first affiliated hospital of kunming medical university from2015, May to 2016, November. Genotypes of the VDR TaqI gene polymorphism were analyzed using the PCR amplification product enzyme and agarose gel electrophoresis.Results A total of 70 NS (42 steroid sensitive [SS]and 28 steroid resistant [SR]) patientswith a mean age of 9.14 ±3.80 years were studied. The TT genotypeof VDR-TaqI polymorphism was detected in 57.1% of the SS patients compared to 57.1% of SR patients (P=1.000) .The Tt genotype was detected in 26.2% of SS patientscompared to 25.0% of SR patients (P =0.911) . The tt genotype was detected in 16.7% of SS patients compared to 17.9% of SR patients (P =0.897) . The T-allele frequency was 70.2% in SS patients compared to 69.6% of SR patients.The t-allele frequency was 29.8% in SS patients compared to 30.4% of SR patients (P =0.096) .No significant difference was detected in terms of VDR-Apal polymorphism in SS patients compared to SR patientsfor all the three genotypes (P =1.000, P =0.911, and P=0.897) . No significant difference was found in any of the allele frequencies between SS and SR (P =0.096) .Conclusion Vitamin D Receptor Gene TaqI polymorphisms has no correlation with the steroid responsiveness in childhood nephrotic syndrome. -
