目的研究溃疡性结肠炎(UC)患者外周血T细胞亚群、红细胞免疫、免疫球蛋白、补体及炎性介质的变化,探讨机体免疫功能变化在UC形成中的作用。方法纳入2014年10月至2015年10月我院收治的UC患者(观察组)、健康体检对象(对照组)各30例。取外周血测T细胞亚群(CD3+、CD4+、CD8+)水平、红细胞C3b受体花环率(RCR)、红细胞免疫复合物花环率(RICR)、血清红细胞C3b受体花环促进率(RFER)及抑制率(RFIR)、免疫球蛋白(IgA、IgG、IgM)水平、补体(C3、C4)水平、炎性介质(TNF-α、IL-6、sIL-2R)水平。结果观察组CD3+明显低于对照组,CD4+/CD8+水平明显高于对照组;观察组RCR、RFER明显低于对照组、RICR、RFIR明显高于对照组;观察组TNF-α、IL-6、sIL-2R水平均明显高于对照组(P均<0.05)。两组其它指标未见明显差异。结论溃疡性结肠炎患者存在T细胞亚群紊乱、红细胞免疫功能缺陷、炎症因子水平上升等现象,监测上述指标有助于评价病情变化,值得关注。

【Abstract】Objective To investigate the changesof T cell subsets,erythrocyte immunity,immune globulin,complementand inflammatorymediators in patientswith ulcerative colitis(UC),and explore the role ofimmune function in the formation ofUC.M ethods 30 patientswith UC(observation group)and healthy physicalexam ination(controlgroup)were treated in our hospital from October 2015 to October 2014.The levelsof T,CD4+,CD3+receptor(CD8+),erythrocyte C3b receptor(RCR),erythrocyte immune complex(RICR),inhibition rate(RFIR),IgA(IgG),IgM(C4),TNF-(IL-6)and C3b(sIL-2R)weremeasured.Results the CD3+levels in the observation group w ere significantly lower than those in the controlgroup,the CD4+/CD8+levelw as significantly higher than that in the control group,the RCR and RFER in the observation group were significantly lower than those in the controlgroup,RICR and RFIRwere significantly higher than those in the control group,the levelsof IL-6,sIL-2R and TNF-in the observation group were significantly higher than those in the control group.Statistically significantdifferenceswere significant(P<0.05).Therewasno significantdifference in other indexes in the two groups.Conclusion T cell subsets disorder,red cell immune function defects,and inflammatory factors increase occur in patientswith UC andmonitoring these indicators ishelpful to evaluate the stateof UC.

溃疡性结肠炎(ulcerative colitis,UC)是慢性非特异性结肠炎症,多表现为炎症或溃疡,可累及直肠及远端结肠,患者临床症状主要为腹痛、便血等,可严重影响其生活质量[1]。目前尚未完全探明UC发生机制,多认为其与免疫、遗传、环境及肠道细菌等多种因素有关[2],但针对性分析UC患者多种免疫功能指标变化情况的研究尚不多见。本研究旨在以我院收治的30例UC患者为对象,探讨UC对外周血T细胞亚群、红细胞免疫、免疫球蛋白、补体及炎性介质的影响,现报道如下。
