摘要
目的:探究Klotho蛋白结合纤连蛋白(FN)在瘢痕疙瘩术后复发的相关性.方法:选取2020 年4 月至2023 年4 月于我科就诊的耳部瘢痕疙瘩患者43 例及普通求美者37 例,实验对象分为研究组(瘢痕疙瘩组织和血清)及对照组(正常组织和血清).采用免疫组织化学染色法及酶联免疫吸附法(ELISA)检测比较两组组织和血清标本中 Klotho 蛋白及上皮间质转化标志物纤连蛋白 FN 的表达.同时在术后1 月、3 月、6 月、12 月对瘢痕疙瘩患者进行随访、记录复发情况,分为复发组及未复发组.应用统计学方法分析 Klotho 的表达与瘢痕疙瘩纤维化标志物 FN 的表达及术后复发的相关性.结果:免疫组化结果:研究组Klotho阳性率较对照组低(P＜0.05),为 37.20%;研究组 FN 阳性率为 72.10%,高于对照组阳性率(P＜0.05);复发组Klotho阳性率为21.40%,低于未复发组(P＜0.01);复发组FN阳性率为92.90%,高于未复发组(P＜0.05).Klotho和FN 两种蛋白水平的相关性存在统计学差异(r=-0.307,P＜0.05);ELISA检测血清结果:研究组Klotho 表达含量为 65.99(55.05,79.06)ng/mL,低于对照组(P＜0.05);研究组 FN 表达含量为 83.56(62.67,91.85)ng/mL,较高于对照组(P＜0.01);经Logrank检验,在术后复发患者中Klotho阴性表达与FN 蛋白阳性表达相关(P 均＜0.05).结论:Klotho蛋白结合上皮间质转化标志物FN可作为预测瘢痕疙瘩术后复发的重要标志物.
Abstract
Objective:To investigate the correlation between Klotho protein binding to fibronectin Fn and postoperative recurrence in keloids.Methods:A total of 43 patients with ear keloids and 37 general cos-metic seekers who visited our department from April 2020 to April 2023 were selected.The subjects were di-vided into a study group(keloid tissues and serum)and a control group(normal tissues and serum).Immu-nohistochemistry and enzyme-linked immunosorbent assay(ELISA)were used to detect and compare the ex-pression of Klotho protein and the epithelial-mesenchymal transition marker fibronectin FN in tissue and serum samples from both groups.Keloid patients were followed up at 1 month,3 months,6 months,and 12 months postoperatively to record recurrence,which divided them into recurrence and non-recurrence groups.Statisti-cal methods were used to analyze the correlation between Klotho expression and fibronectin FN expression and postoperative recurrence in keloids.Results:Immunohistochemistry results showed that the positive rate of Klotho in the study group was lower than in the control group(P＜0.05),at 37.20%.The positive rate of FN in the study group was 72.10%,higher than in the control group(P＜0.05).The positive rate of Klotho in the recurrence group was 21.40%,lower than in the non-recurrence group(P＜0.01),and the positive rate of FN in the recurrence group was 92.90%,higher than in the non-recurrence group(P＜0.05).There was a statistically significant correlation between the levels of Klotho and FN proteins(r=-0.307,P＜0.05).Elisa results showed that the expression level of Klotho in the study group was 65.99(55.05,79.06)ng/mL,lower than in the control group(P＜0.05),and the expression level of FN in the study group was 83.56(62.67,91.85)ng/mL,higher than in the control group(P＜0.01).Logrank tests indicated that negative Klotho expression and positive FN protein expression were associated with postoperative recurrence(both P＜0.05).Conclusion:The combination of Klotho protein and the epithelial-mesenchymal transition marker FN can be used as an important marker to predict postoperative recurrence of keloids.
