摘要
目的探讨原发陛胆汁陛肝硬化(PBC)患者肝脏雌激素受体(ER-仅)与外周血T淋巴细胞亚群细胞因子和自身抗体的相关性。方法采取横断面研究方法,设未治疗的80例女性PBC患者为PBC组;健康对照组为10例基线匹配的健康女性志愿者;非PBC对照组为20例非自身免疫陛肝病患者,ELISA法检测各组外周细胞因子:白细胞介素6(IL-6)、IL-8、IL_22、肿瘤坏死因子α(TNF-α)、干扰素γ(IFNγ);自身抗体:M2型抗线粒体抗体(AMA-M2)、抗-Sp00及抗-gp210水平;免疫组织化学法检测PBC组及非PBC对照组肝组织ER-α的表达,指标相关性采用spea彻an相关f生检验,数值资料比较采用秩和检验。结果与健康对照组相比,PBC组和非PBC对照组的细胞因子水平显著升高;而PBC组和非PBC对照组比较,差异无统计学意义。PBC组肝组织ER-cc阳性率为(50.7±8.9)%显著高于非PBC对照组(10.2±2.8)%,z=4.82,P〈0.05,差异有统计学意义。PBC组肝组织ER-α阳性率与血清AMA-M2、抗-SPl00、抗-gp210的阳性率呈正相关,相关系数,分别为0.898、0.819和0.814,P值均〈0.05,差异有统计学意义;ER-α与血清细胞因子IL-22、TNF-α、IFNv的含量也呈正相关,相关系数,分别为0.71、0.89和0.82,P〈0.05,差异有统计学意义。非PBC对照组血清AMA-M2、抗-Sp100、抗-gp210为阴性,肝组织ER-α表达与血清细胞因子水平无相关性(P〉0.05)。结论PBC患者血清细胞因子水平和ER-α阳性率显著升高,与自身抗体阳性率呈正相关,提示PBC患者肝组织高表达ER-α,可能是PBC的发病原因之一。
Objective To investigate the correlation between ER-α in the liver and cytokines of T lymphocytes subsets and serum signatures in PBC patients. Methods The research is performed with cross- sectional study. 80 PBC women patients without treatment were enrolled in PBC group, 10 healthy women as baseline-matched in healthy-control group, and 20 patients with non-autoimmune liver disease in non-PBC control group. The expression of IL-6, IL-8, IL-22, TNF-α, IFNγ AMA-M2, Sp 100 and gp210 were analyzed in Peripheral Blood using ELISA in all groups, and ER-α of patients were performed on tissues from liver biopsies in PBC group and non-PBC control group with immunohistochemistry. Spearman correlation test were performed on the indices to identified the association of all Parameters. numerical data were compared with Wilcoxon rank-sum test. Results Compared with healthy-control group, expression of serum cytokines are significantly higher in PBC and non-PBC groups (P 〈 0.01), while no significant difference were observed between PBC and non-PBC groups. The positive rate of ER-α in PBC patients liver tissues in PBC group is higher than that in non-PBC group (Z =4.82, P〈 0.01 ). Expression of ER-α is positively correlated with positive rates of AMA-M2 antibody, Sp 100 and gP210 of tissues of PBC patients (r= 0.898, 0.819, 0.814, P 〈 0.01 ). ER-α is positive correlated with the expression o f cytokines, among which the coefficient of correlation of IL-22, TNFα, IFNγ is more than 0.7(r=0.71, 0.89, 0.82,P〈0.01), AMA-M2, Spl00, gp210 is negative in serum of non-PBC control group. No obviously correlations were indicated between the expression of ER-α and cytokines. Conclusion A high level of expression of cytokines in the serum might be one of the factors of etiopathogenisis of PBC.
