摘要: 目的 探究非哺乳期乳腺炎(NPM)患者外周血及单核细胞来源高迁移率族蛋白B1(HMGB1)水平变化及与病情的相关性。方法 共83例NPM患者根据病情分为急性组(acute)42例和慢性组(chronic)41例,另以40例健康受试者作为对照组(control)。采用ELISA检测各组的外周血HMGB1、C反应蛋白(CRP)、白细胞介素6(IL-6)水平;流式细胞测量术检测单核细胞的数量及HMGB1水平;qPCR和Western blot检测单核细胞中HMGB1表达;Pearson法分析单核细胞的HMGB1表达与外周血CRP、IL-6水平的相关性。绘制ROC曲线评估单核细胞的HMGB1表达水平对NPM病情的诊断价值。结果 NPM患者的外周血HMGB1、CRP、IL-6水平、M1型单核细胞数量及单核细胞的HMGB1 mRNA均高于对照组,同时急性组高于慢性组(P<0.05)。单核细胞的HMGB1 mRNA水平与外周血CRP(r=0.426)、IL-6(r=0.569)呈正相关(P均<0.05)。M1型单核细胞的HMGB1蛋白水平诊断NPM的AUC为0.739(95% CI:0.67~0.82),敏感度与特异度分别为69.8%和77.2%;评估病情的AUC为0.828(95% CI:0.73~0.91),敏感度与特异度分别为83.3%和71.4%。结论 NPM患者外周血单核细胞上HMGB1表达水平增加,且其与外周血CRP、IL-6水平呈正相关,有助于NPM诊断及病情评估。

Abstract: Objective To investigate the changes in peripheral blood and monocyte-derived high mobility group protein B1 (HMGB1) levels in patients with non-puerperal mastitis (NPM) and their correlation with the disease. Methods A total of 83 patients with NPM were divided into the acute group (42 cases) and the chronic group (41 cases) according to their conditions Additionally, 40 healthy subjects were taken as the control group. The levels of HMGB1, C-reactive protein (CRP), and interleukin-6 (IL-6) in the peripheral blood of each group were detected by ELISA. The number of monocytes and the level of HMGB1 were detected by flow cytometry; the expression of HMGB1 in monocytes was detected by qPCR and Western blot; the correlation between the expression of HMGB1 in monocytes and the levels of CRP and IL-6 in peripheral blood was analyzed by the Pearson method. ROC curves were constructed to evaluate the diagnostic value of HMGB1 expression level in monocytes for the condition of NPM. Results The levels of HMGB1, CRP, IL-6 in the peripheral blood of patients with NPM, the number of M1-type monocytes and the HMGB1 mRNA expression in monocytes were all higher than those in the control group. Meanwhile, these levels in the acute group were higher than those in the chronic group (P<0.05). The level of HMGB1 mRNA in monocytes was positively correlated with CRP (r=0.426) and IL-6 (r=0.569) in peripheral blood (all P<0.05). The AUC of HMGB1 protein level in M1 monocytes for diagnosing NPM was 0.739 (95% CI: 0.67-0.82), the sensitivity and specificity were 69.8% and 77.2%. The AUC for evaluating the disease condition was 0.828 (95% CI: 0.73-0.91), the sensitivity and specificity were 83.3% and 71.4%. Conclusions The expression of HMGB1 in monocytes of patients with NPM increases and is positively correlated with the levels of peripheral blood CRP and IL-6, which is helpful for the diagnosis and condition assessment of NPM.
