摘要
目的探讨健康人群趋化因子CXC配体16(CXCL16)基因多态性与血清CXCL16、C反应蛋白(CRP)水平的相关性。方法采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP)方法检测204名健康体检者CXCL16基因A181V多态性,同时分别应用酶联免疫吸附试验(ELISA)和免疫比浊法检测血清CXCL16和高敏CRP(hs-CRP)水平,并进行统计学分析。结果 AA基因型血清hs-CRP水平明显高于GG、GA基因型(P=0.01);多元线性回归显示A等位基因是高hs-CRP水平的独立危险因素(OR=1.25,95%CI:1.08~2.59,P=0.021);以血清hs-CRP水平中位数(0.91 mg/L)为界定值分为2组,AA基因型和A等位基因频率在hs-CRP〉0.91 mg/L组中显著升高(P=0.008,0.036);而血清CXCL16水平与其基因型间差异无统计学意义(P〉0.05)。结论 CXCL16基因A181V位点基因多态性与血清hs-CRP水平相关,A等位基因可能参与机体炎症反应的发生、发展。
Objective To investigate the association of serum chemokine CXC ligand 16(CXCL16)and C reactive protein(CRP) levels with CXCL16 gene polymorphism in healthy subjects.Methods The polymorphisms of CXCL16 gene A181V were detected in 204 healthy subjects by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).Enzyme-linked immunosorbent assay(ELISA) and particle-enhanced immunonephelometry were used to detect serum CXCL16 and high sensitive CRP(hs-CRP) levels respectively,and the results were analyzed statistically.Results Serum hs-CRP levels in AA genotype were significantly higher than those in GG and GA genotypes(P=0.01).Multiple linear regression showed that A allele was an independent risk factor of high-level hs-CRP(OR=1.25,95%CI:1.08-2.59,P=0.021).2 groups were set according to the median of hs-CRP levels(0.91 mg/L).AA genotype and A allele frequencies were significantly higher in group with higher hs-CRP level than those in group with lower one(P=0.008,0.036).However,there was no significant difference between serum CXCL16 levels and its genotypes(P〈0.05).Conclusions CXCL16 gene A181V polymorphism is associated to serum hs-CRP levels,and A allele may be involved in the occurrence and development of inflammatory response.
