[Abstraci]Objechva To analyze the expmss/x of P16protein in different levels of cervical inWaeyitheligi neoplasia and its di/laent functiox in the auxi/arp diagnosis.Methods113pa/ents with CIN were selected in the study and all the pa/ents with cervical biopsy specimens or couiza/ox were collected.According to the pathologio results,the pahents were divided into CIN I group with43cases i CIN II group with57cases,CIN III group with48cases and25cases of benign les/xs.The expressioxs of P16protein in each group were measured by immunoUistochemishp and the data was analyzed.Res
ults The positive expmss/x rate of P16protein in different lee-els of cervical squamous inhaepitUelivi les/xs sUowed an increasing Wend.Compared with the coxhci group,the difference was sm/sti-cally significant(P<425).The differences wem also sm/stica/p significant in the expenmenmi group(P<4.45).Conclusion The expmss/x of P16protein is correlated with the grading of cervical inhaepithe/vi les/xs,which could be used as a clinical indicator for stm/fied management cervical les/xs.

宫颈上皮内瘤变(CIN)为宫颈癌前病变,及时和精准诊治对其转归和预防发展为宫颈癌具有重要意义。只有尽早对CIN进行准确分级,且提出合理化管理,才能真正降低宫颈癌的发病率和病死率[-8]。病理诊断是CIN诊断和分级的金标准⑷,有关研究报道表明在不同的病理学医师之间高级别CIN诊断的可重复性较好9氐级别CIN的可重复性较差[「4]。因此,寻一种鉴别不同级别宫颈鳞状上皮变的用分级诊断分的。
前,通过分子标志物检测对肿瘤进行诊断是国内外的研究热点,有关文献报道2「7]P10基因在宫颈病变进展过程中是一个较有价值的标志物。本研究旨在通过检测pl6蛋白表达以探讨其在宫颈病变中的辅

1资料与方法
91一般资料:收集2017年5月-2619年7月期间宁夏医科大学总医院经宫颈活检、宫颈锥切确诊为SIL的宫颈上皮组织石蜡包埋标本共115例,其中CIN I43例,年龄10-69(40.07±1922)岁;CIN I27例,年龄29-63(9975±1125)岁;CIN皿48例,年龄21-70(40.00±1934)岁。因妇科良性疾病行全子宫切除的正常宫颈组织20例,年龄40-69 (5328±621)岁。所有患者术前均未接受激素,经两位中级以上职称病理学专科医生确诊。
12试验方法
12.1yl6蛋白检测方法:采用免疫组化SP法检测 P16蛋白的表达。具体步骤:宫颈组织石蜡标本切片^45°C烘烤、脱蜡、水化—3%去离子水去除内源性过氧化物酶—柠檬酸高压热修复抗原—用兔抗人P10免疫组化试剂盒,SP法行免疫组化染,严格按空调一晚上几度电
