1、乙醇對(duì)慢性丙型肝炎患者HCV基因型分布及肝損害的影響作者:孫慧慧 王敏 張孝國(guó) 陳建 劉靚文 智緒亭【摘要】目的:對(duì)比嗜酒與非嗜酒的慢性丙型肝炎(chronichepatitisC,CHC)患者HCVRNA基因型及分布,以明確嗜酒的CHC患者病情發(fā)展是否與某種特定基因型有關(guān)。檢測(cè)CHC患者IFN-γ及TNF-α水平,了解嗜酒的HCV感染者肝損害的機(jī)制。方法:收集CHC患者114名,分為嗜酒組和非嗜酒組,以基因芯片技術(shù)對(duì)2組患者進(jìn)行HCVRNA基因分型。采用Ficoll梯度離心法提取所有患者外周血單個(gè)核細(xì)胞(PBMC)并培養(yǎng),
2、ELISA法檢測(cè)IFN-γ及TNF-α的水平。結(jié)果:嗜酒組和非嗜酒組HCVRNA的基因型均以1b型為主(嗜酒組的比例為60%,非嗜酒組為43.75%),二者之間無統(tǒng)計(jì)學(xué)意義(P=0.22)。嗜酒組和非嗜酒組的HCVRNA定量測(cè)定分別為(11100±14174.3)×103mL-1和(3927.8±4549.6)×103mL-1,二者比較差異有統(tǒng)計(jì)學(xué)意義(P=0.025)。嗜酒組和非嗜酒組TNF-α水平分別為(4528±3587)ng/L和(3262±3131)ng/L,二者相比差異有統(tǒng)計(jì)學(xué)意義(P=0.048),但2組IFN
3、-γ水平差異無統(tǒng)計(jì)學(xué)意義(P>0.05)。結(jié)論:乙醇促CHC肝患者HCVRNA復(fù)制,導(dǎo)致肝損傷加重,但并不能增加慢性HCV感染者對(duì)某種HCVRNA基因型的易感性。TNF-α在嗜酒的CHC患者中起重要作用,是導(dǎo)致肝損害的重要細(xì)胞因子之一。13【關(guān)鍵詞】肝炎病毒,丙型·乙醇·基因型·IFN-γ·TNF-α 【ABSTRACT】Objective:ToanalyzethegenotypesofHCVRNAinalcoholicandnonalcoholicHCVpatientsandcontrastthedistribut
