目的  研究C-C亞族趨化因子單核細胞趨化蛋白-4(MCP-4/CCL13)在系統性紅斑狼瘡(SLE)患者外周血的表達水平,并分析MCP-4的水平與狼瘡腎炎的關系,以探討MCP-4在SLE發病機制中可能起的作用。 方法  選取2007年9月-2010年8月在四川大學華西醫院和宜賓市第一人民醫院診斷明確的SLE及類風濕關節炎(RA)患者各40例。另收入正常健康對照組(20例),應用酶聯免疫吸附試驗定量方法測定SLE組、RA患者和正常健康對照者血清中MCP-4的水平,SLE患者根據有無腎臟受累分為非狼瘡腎炎組和狼瘡腎炎組,其中非狼瘡腎炎組20例,狼瘡腎炎組20例,并分析SLE組血清MCP-4水平是否與抗核抗體、補體C3、C4等指標及SLE疾病活動指數SLEDAI評分相關性,血清MCP-4水平采用方差分析、LSD-t檢驗和Spearman相關進行統計分析。 結果  血清MCP-4水平SLE組為(216.32 ± 12.65)pg/mL,RA組為(203.79 ± 18.64)pg/mL,正常健康對照組為(125.13 ± 11.08)pg/mL。SLE組、RA組血清MCP-4水平與正常健康對照組相比均有統計學意義(P<0.05),SLE組與RA組比較血清MCP-4水平無統計學意義(P>0.05);SLE患者中狼瘡腎炎組與非狼瘡腎炎組比較血清MCP-4水平無統計學意義(P>0.05)。SLE組血清MCP-4水平與抗核抗體、補體C3、C4等指標及SLEDAI評分無相關性。 結論  MCP-4在SLE組患者血清中表達增高,MCP-4可能參與了SLE的發病過程,可能成為SLE新的血清學有用指標并作為治療的靶點。
