摘　　要：目的:探究膀胱癌组织壳多糖酶3样蛋白1(chitosanase 3-like protein 1,CHI3L1)、Y性别决定基因7(sex determining region Y-box,SOX7)表达及与经尿道膀胱肿瘤电切术(transurethral resection of bladder tumors,TURBT)术后复发的关系。方法:收集2019年8月—2021年8月保定市第二医院收治的146例行TURBT的膀胱癌患者作为观察对象,取患者癌组织和癌旁组织,采用免疫组织化学法测定膀胱癌组织和癌旁组织CHI3L1、SOX7蛋白表达,对患者进行2年随访,根据术后复发情况,分为复发组32例和未复发组114例,采用logistic回归分析膀胱癌患者TURBT术后复发的影响因素,四格表分析膀胱癌组织CHI3L1、SOX7蛋白表达对TURBT术后复发的预测价值。结果:膀胱癌组织CHI3L1阳性表达率(65.75%)显著高于癌旁组织(34.93%),SOX7阳性表达率(41.10%)显著低于癌旁组织(73.29%)(P<0.05)。肿瘤数目多发、T1期的膀胱癌组织CHI3L1阳性表达和SOX7阴性表达的患者比例显著高于肿瘤数目单发、Ta期的患者比例(P<0.05)。CHI3L1是膀胱癌患者TURBT术后复发的独立危险因素,SOX7是复发的保护因素(P<0.05)。CHI3L1、SOX7联合预测术后复发的特异度、准确度高于各自单独预测,误诊率低于各自单独预测(P<0.05)。结论:在膀胱癌组织中CHI3L1表达水平较高,SOX7表达水平较低,二者与患者临床病理特征以及TURBT术后复发有关,可能作为膀胱癌患者行TURBT术后预后评估的标志物。Objective To investigate the expression of chitosanase 3-like protein 1(CHI3L1)and sex determining region Y-box 7(SOX7)in bladder cancer tissue and their relationship with the recurrence after transurethral resection of bladder tumor(TURBT).Methods A total of 146 cases of bladder cancer treated by TURBT in Baoding Second Hospital from August 2019 to August 2021 were collected as observation objects,then immunohistochemical method was applied to detect the expression of CHI3L1 and SOX7 proteins in bladder cancer tissues and adjacent tissues.Patients were followed up for 2 years and grouped into a recurrence group of 32 cases and a non-recurrence group of 114 cases based on postoperative recurrence.Logistic regression was applied to analyze the factors influencing the recurrence of bladder cancer after TURBT,and the predictive value of CHI3L1 and SOX7 protein expression in bladder cancer tissues for recurrence after TURBT was analyzed by four-fold table.Results The positive expression rate of CHI3L1 in bladder cancer tissues(65.75%)was obviously higher than that in adjacent tissues(34.93%),while the positive expression rate of SOX7(41.10%)was obviously lower than that in adjacent tissues(73.29%)(P<0.05).The proportions of positive expression of CHI3L1 and negative expression of SOX7 in patients with multiple tumors,and T1 tumor stage were obviously higher than those in patients with single tumor and Ta tumor stage(P<0.05).CHI3L1 was an independent risk factor in recurrence of bladder cancer after TURBT,while SOX7 was a protective factor in recurrence(P<0.05).The specificity and accuracy of CHI3L1 and SOX7 combined to predict postoperative recurrence were higher than those of each individual prediction,and the misdiagnosis rate was lower than that of each individual prediction(P<0.05).Conclusion CHI3L1 is highly expressed,while SOX7 is lowly expressed in bladder cancer tissues.Both are related to the clinicopathological characteristics of patients and the recurrence after TURBT,so they may be used as markers for the
