摘要:

目的 探讨三结构域家族蛋白22(TRIM22)基因表达在溃疡性结肠炎(UC)患者中的临床意义。方法 从GEO数据库中下载UC数据集GSE119600,进行生物信息学分析。选取2023年12月—2024年6月南京医科大学第一附属医院UC患者62例(UC组)、健康体检者60名(正常对照组)。检测所有研究对象血清TRIM22基因相对表达量。根据改良Mayo评分将UC患者分为非活动期组(22例)和活动期组(40例)。根据溃疡性结肠炎内镜严重程度指数(UCEIS)评分将所有患者分为轻度组(16例)、中度组(19例)和重度组(27例)。根据治疗3个月后的内镜复查结果将活动期UC患者分为预后良好组(29例)和预后不良组(11例)。采用Spearman相关分析评价UC患者血清TRIM22与实验室常规指标的相关性。采用Logistic回归分析评估UC发生的影响因素。采用受试者工作特征(ROC)曲线评估TRIM22判断UC患者病情和预后不良的效能。结果 TRIM22参与了抗病毒反应、干扰素介导的信号通路、炎症性肠病等生物学途径。UC组血清TRIM22基因相对表达量显著高于正常对照组(P<0.001)。活动期组血清TRIM22基因相对表达量高于非活动期组(P=0.012)。重度组血清TRIM22基因相对表达量显著高于轻度组和中度组(P<0.001)。与治疗前比较,治疗3个月后预后良好组血清TRIM22基因相对表达量降低(P=0.025)。C反应蛋白(CRP)水平升高和TRIM22表达升高均是UC发生的独立危险因素[比值比(OR)值分别为1.10、1.69,95%可信区间(CI)分别为1.85~9.40、1.15~2.48,P<0.05]。TRIM22判断UC为活动期、病情为重度和预后不良的曲线下面积(AUC)分别为0.71、0.77、0.76。结论 UC患者血清TRIM22表达显著升高,且与病情严重度有关,或可作为UC潜在的分子标志物。

Abstract:

Objective To investigate the clinical significance of tripartite motif-containing protein 2(TRIM22) gene expression in patients with ulcerative colitis(UC). Methods The UC dataset GSE119600 was downloaded from the GEO database for bioinformatics analysis. Totally,62 patients with UC(UC group) and 60 healthy subjects(healthy control group) at the First Affiliated Hospital of Nanjing Medical University from December 2023 to June 2024 were enrolled. The relative expression levels of serum TRIM22 gene were determined. UC patients were classified into non-active group(22 cases) and active group(40 cases) according to the modified Mayo score. All the patients were classified into mild,moderate and severe groups according to the ulcerative colitis endoscopic index of severity(UCEIS) score. The active UC patients were classified into good prognosis group(29 cases)and poor prognosis group(11 cases)based on the endoscopic reexamination results after 3 months of treatment. Spearman correlation analysis was used to evaluate the correlation between serum TRIM22 and laboratory routine indicators in UC patients. Logistic regression analysis was used to assess the influencing factors of UC. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of TRIM22 in judging the severity and poor prognosis of UC patients. Results TRIM22 was involved in anti-viral responses,interferon-mediated signaling pathways and inflammatory bowel diseases. The relative expression level of serum TRIM22 gene of UC group was higher than that of healthy control group(P<0.001). The relative expression level of serum TRIM22 gene in active group was higher than that in non-active group(P=0.012). The relative expression level of serum TRIM22 gene in severe group was higher than those in mild and moderate groups(P<0.001). Compared with before treatment,the relative expression level of serum TRIM22 gene in good prognosis group after 3 months of treatment was decreased(P=0.025). Elevated C-reactive protein(CRP) levels and TRIM22 expression were independent risk factors for the occurrence of UC [odds ratios(OR) were 1.10 and 1.69,95% confidence intervals(CI) were 1.85-9.40 and 1.15-2.48,P<0.05]. The areas under curves(AUC) of TRIM22 for judging the active stage of UC,severe disease condition and poor prognosis were 0.71,0.77 and 0.76,respectively. Conclusions TRIM22 is expressed in the serum of UC patients and is related to the severity of the disease. TRIM22 is expected to become a potential molecular marker for UC.
