摘　　要：目的探讨降钙素基因相关肽(CGRP)rs155209和受体活性蛋白1(RAMP1)rs3754701两个基因位点突变是否与干扰素治疗慢性乙型肝炎(乙肝)预后有关。方法采用调查问卷的方法收集317例研究对象的一般资料,收集其抗凝血,提取DNA,用基质辅助激光解吸电离飞行时间质谱实验平台进行SNPs分型,使用单因素及多因素logistic回归方法分析CGRP及RAMP1基因多态性与干扰素治疗慢性乙肝预后的关系。结果携带RAMP1基因rs3754701T者更容易出现DNA应答和ALT应答(OR=2.277,95%CI:1.386~3.741,P=0.001;OR=1.694,95%CI:1.073~2.675,P=0.024),而携带CGRP基因rs155209C者更不易出现DNA应答和ALT应答(OR=0.150,95%CI:0.083~0.271,P<0.001;OR=0.583,95%CI:0.367~0.925,P=0.022)。结论在中国北方汉族人群中,CGRP基因的rs155209和RAMP1基因的rs3754701位点与干扰素治疗慢性乙肝预后有关,rs3754701T在干扰素治疗后的DNA应答和ALT应答中起保护作用,而rs155209C携带者不易出现DNA应答和ALT应答。Objective To analyze the association of two single-nucleotide polymorphisms(SNP)[Calcitonin gene related peptide(CGRP)rs155209 and receptor activity modifying protein 1(RAMP1)rs3754701]and the prognosis of chronic hepatitis B patients who were under interferon therapy.Methods A total of 317 patients and their anticoagulant blood samples were collected in this study.The SNPs in the CGRP and region RAMP1 were genotyped using matrix-assisted laser desorption/ionization time of flight mass spectrometry.Logistic regression method was used to assess the results from different phenotypic outcomes between cases and controls,after adjusted for sex and age in co-dominant,dominant and recessive genetic models.Results Data from this study clearly demonstrated the relevance of CGRP rs155209 and RAMP1 rs3754701 with DNA response and ALT response.RAMP1 rs3754701T was strongly associated with both DNA response and ALT response(OR=2.277,95%CI:1.386-3.741,P=0.001;OR=1.694,95%CI:1.073-2.675,P=0.024).However,CGRP rs155209C was less prone to DNA response and ALT response(OR=0.150,95%CI:0.083-0.271,P<0.001;OR=0.583,95%CI:0.367-0.925,P=0.022).Conclusions Results from our study suggested that both RAMP1 rs3754701 and CGRP rs155209 were associated with the prognosis of patients under interferon therapy in Han population,from the northern parts of China while RAMP1 rs3754701T was a protective factor for both ALT response and DNA response,but CGRP rs155209C carriers were less prone to DNA and ALT responses.
