摘　　要：目的探讨慢性乙型肝炎(CHB)患者血清铁调素(Hepc)和铁代谢指标的变化,并在体外观察HBV转染肿瘤细胞Hepc表达的变化。方法在71例CHB患者和24例健康体检者,采用ELISA法检测血清Hepc水平,使用全自动蛋白分析仪检测血清铁(SI)、铁蛋白(Ferr)和转铁蛋白(Tf)水平。使用电化学发光全自动免疫分析仪检测血清IL-6水平。构建HBV感染Huh7细胞模型,分别采用RT-qPCR和Western blot法检测细胞Hepc表达情况。结果与健康人比较,CHB组血清SI、Ferr、IL-6、丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、血清总胆红素(TBIL)水平均显著升高,Hepc、Tf和可溶性转铁蛋白受体(sTfR)、白蛋白(ALB)显著降低(P<0.05);转染细胞24 h,Hepc mRNA相对水平为(5.21±0.43),空白对照细胞的(0.73±0.14)显著升高(P<0.05),在转染48 h,细胞Hepc mRNA水平为(8.45±0.61),较空白对照的(1.16±0.17)显著升高(P<0.05);在质粒转染48 h后,细胞Hepc蛋白相对表达量为(0.78±0.08),较空白对照的(0.41±0.02)显著升高(P<0.05)。结论检测铁调素及其铁代谢相关指标有助于评估慢性乙型肝炎病情进展,适当予以铁调素或者其相应内源性激活剂针对性地治疗铁超载CHB患者,是否可应用于临床,值得期待。Objective To investigate the changes of serum hepcidin and iron metabolism index in patients with hepatitis B and in pC1.3 plasmid containing HBV genome-transfected Huh7 cells in vitro.Method 71 patients with CHB and 24 healthy subjects were recruited in this study,and serum hepcidin,serum iron(SI),ferritin(Ferr),and transferrin(Tf)as well as IL-6 levels were detected.The HBV-infected Huh7 cells were constructed,and the expression of Hepc were detected by RT-PCR and Western blot,respectively.Result Serum SI,Ferr,IL-6,alanine aminotransferase(ALT),serum aspartate aminotransferase(AST),and serum total bilirubin(TBIL)levels were significantly elevated and serum Hepc,Tf,soluble transferrin receptor(sTfR),and albumin(ALB)levels were significantly decreased(P<0.05)in patients with CHB as compared to those in healthy persons(P<0.05);the relative levels of Hepc mRNA in HBV-transfected Huh7 cells at 24 h after transinfection was(5.21±0.43),significantly higher than(0.73±0.14)in vacant plasmid-infected Huh7 cells(P<0.05),and at 48 h,it was(8.45±0.61),also significantly higher than(1.16±0.17)in the control(P<0.05);the relative expression of Hepc protein in HBV-transfected Huh7 cells at 48 h of plasmid transfection was(0.78±0.08),significantly higher than(0.41±0.02)in the vacant(P<0.05).Conclusion Detection of hepcidin and iron metabolism-related indicators might help to assess the progress of chronic hepatitis B,and an appropriate administration of hepcidin or its corresponding endogenous activators needs clinical trials.
