卵巢上皮性癌中RBM3及CD146的表达与临床意义(1)
【摘要】 目的:分析总结卵巢上皮性癌中CD146、RNA结合基序蛋白3(RBM3)的表达与临床意义。方法:选取2018年1-12月50例卵巢上皮性癌组织标本、25例卵巢上皮良性肿瘤组织标本、同期因其他手术治疗切除25例正常卵巢组织标本,经免疫组织化学法对所有标本的RBM3及CD146表达水平进行分析。结果:卵巢上皮性癌组织中CD146与RBM3阳性表达率均高于卵巢上皮良性肿瘤与正常卵巢组织(P<0.05);卵巢上皮性癌FIGO Ⅲ、Ⅳ期RBM3与CD146表达阳性率均高于Ⅰ、Ⅱ期,中低分化卵巢上皮性癌RBM3与CD146表达阳性率均高于高分化,但差异均无统计学意义(P>0.05)。结论:RBM3及CD146参与卵巢上皮性癌的形成,临床诊断工作中应引起足够的重视。

[Abstract] Objective: To analyze the expression and clinical significance of CD146 and RNA-binding motif protein 3 (RBM3) in epithelial ovarian cancer. Method: From January to December 2018, 50 cases of ovarian epithelial carcinoma tissues, 25 cases of ovarian epithelial benign tumor tissues, and 25 cases of normal ovarian tissues removed due to other surgical treatments during the same period were selected. The expression levels of RBM3 and CD146 in all samples were analyzed by immunohistochemistry. Result: The positive expression rates of CD146 and RBM3 in ovarian epithelial carcinoma tissues were higher than those in ovarian epithelial benign tumors and normal ovarian tissues (P<0.05). The positive expression rates of CD146 and RBM3 in ovarian epithelial carcinoma tissues FIGO Ⅲ, Ⅳ stage were higher than those in Ⅰ, Ⅱ stage, and the positive expression rates of RBM3 and CD146 in middle and low differentiated ovarian epithelial carcinoma were higher than those in high differentiated, but the differences were not statistically significant (P>0.05). Conclusion: RBM3 and CD146 are involved in the formation of epithelial ovarian cancer, and should be paid enough attention in clinical diagnosis.

卵巢癌为一种常见危及女性生命健康的恶性肿瘤,据统计,其发生率逐年升高,其中卵巢上皮性癌最为常见。因卵巢所处位置隐匿,早期确诊难度大,多数患者病情确诊已处于晚期,导致患者5年存活率仅为30%~40%,威胁着女性生命健康[1]。关于该疾病的诊断方法多样,但仪器检测均为侵入性操作,会给患者造成不可避免的应激损伤,而随着临床诊断技术发展,临床提出可采用分子诊断[2]。近些年研究提出,CD146分子、RNA结合基序蛋白3(RBM3)的特异表达与恶性黑色素瘤、乳腺癌、卵巢癌等在内的癌症疾病发生密切相关,但关于CD146、RBM3表达在卵巢上皮性癌的研究较少[3]。本次研究中,积极分析CD146、RBM3在卵巢癌组织中的阳性表达,用于指导临床诊治。现报道如下。
1 资料与方法
1.1 一般资料 选取2018年1-12月本院住院患者50例卵巢上皮性癌组织标本、25例卵巢上皮良性肿瘤组织标本、同期因子宫脱垂手术切除的25例正常卵巢组织标本。纳入标准:所有标本经HE染色后,需由两名经验丰富的病理医生共同阅片检查,符合卵巢上皮良性肿瘤或卵巢上皮性癌诊断标准。排除标准:合并肝肾功能异常、心肺功能异常等严重内外科疾病者;严重精神疾病、不能配合治疗者;术前未接受内分泌、化疗、放疗治疗者。该研究对象知情同意,且经医学伦理委员会批准同意。
1.2 方法 对各组织上的RBM3与CD146表达,经免疫组化技术定位、定性检测,主要免疫组化技术实验步骤:(1)筛选蜡块。登记每个病例的玻片号,在玻片库中,找到具体病例玻片,于显微镜下筛选最佳适合实施免疫组化玻片,并将所选择的玻片登记具体的信息。根据登记玻片信息,从蜡块库中挑选对应蜡块,制作组织切片。(2)高压抗炎修复操作:常规组织切片经二甲苯进行脱蜡处理以及梯度酒精水化处理后,浸泡在蒸馏水中,留作待用。取pH值6.0柠檬酸盐缓冲液(800~1 500 mL)放入压力锅中,大火加热处理,直至沸腾,脱蜡水化后,组织切片放入耐高温或不锈钢切片架上,加入已经沸腾缓冲液中。盖上锅盖,扣上压力阀,继续加热直至喷气。自开始喷气计时,1~2 min后,拿开压力锅,冷却到室温下,将玻片取出,经蒸馏水冲洗2次,用PBS冲洗2次,冲洗时间3 min/次。(3)免疫组化染色步驟:切片脱蜡处理后进行冲洗,安装固定好塑料栏,并用蒸馏水冲洗。将柠檬酸液加入塑料栏中,之后放入微波炉中进行抗原修复。之后取出冷却15 min,倒掉柠檬酸液,再次经蒸馏水冲洗,玻片放入到试剂盒画圈,画圈后经PBS冲洗。冲洗后,加入过氧化氢,于室温下进行孵育,孵育时间10 min。PBS至少冲洗3遍后,去掉PBS,将一抗分别加入到增强剂中,于室温下孵育至少20 min。PBS冲洗3遍后,加入二抗,于室温下孵育30 min。PBS冲洗3遍后,甩去PBS液,将新调配好的DAB液体加入到每张切片上,PBS冲洗3次,冲洗时间3 min/次。采用自来水或蒸馏水冲洗,利用苏木素进行复染,采用0.1%盐酸分化,并用自来水冲洗,PBS冲洗变蓝。自来水冲洗,切片经梯度酒精进行脱水干燥处理后,采用中性树胶进行封片操作。, 百拇医药(曾丹 华金仁 安云婷)
