方法便利选取该院2016年3月—2017年3月确诊的子宫颈上皮内瘤变CINⅡ~Ⅲ级并拟行宫颈环切术的未孕者80例为研究对象,根据切割深度(≥或<15mm)分为观察组和对照组。
观察组切割深度≥15mm,对照组<15mm。
术后对两组患者进行随访,对比分析两组患者受孕时间及妊娠结局有无差异。
结果术后随访3年,观察组成功妊娠28例,妊娠率为70.0%,对照组成功妊娠31例,妊娠率为77.5%,两组比较差异无统计学意义(χ2=0.581,P>0.05)。
两组孕妇妊娠结局方面,胎儿病死率、剖腹产率、妊娠时间、新生儿体质量及Apgar 评分差异无统计学意义(P>0.05);术后随访3年,对照组复发6例,观察组复发0例,对照组术后复发风险高于观察组,差异有统计学意义(χ2=4.505,P<0.05)。
结论宫颈上皮内瘤变患者行LEEP 刀宫颈环切术深度对妊娠率及妊娠结局无明显影响,但切割深度≥15mm 可显著降低术后复发风险。

宫颈上皮内瘤变发生的相关危险因素分析目的调查分析宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)发生的相关危险因素。
方法对入组的148例宫颈疾病患者(包括CIN组105例和宫颈炎组43例)通过问卷调查的形式采集相关资料分析CIN发生的相关危险因素。
结果经单因素非条件Logistic回归分析,首次性生活年龄、妊娠次数、性生活频率和性生活前清洗习惯这4项因素差异有统计学意义(P 3次是CIN发生的危险因素(P 0.05),具有可比性。
1.2 方法在纳入研究的调查对象知情同意的基础上,采用自编问卷进行调查,其内容主要包括被调查对象的年龄、受教育程度、职业、吸烟史、饮酒史、既往病史及用药史、月经史、初次性行为的年龄、首次生产年龄、孕产史、避孕史、宫颈癌家族史、宫颈细胞学检查史、行为与习惯、相关知识的了解程度等。
调查问卷均由调查员进行一对一详细询问填写。
1.3 统计学方法建立Epi Data和Excel数据库,应用SPSS 13.0软件对数据进行统计分析,采用单因素及多因素非条件Logistic回归分析CIN发生的相关影响因素,以P 3次是CIN发生的危险因素,性生活前双方清洗阴部是CIN的保护因素。

3 讨论CIN是宫颈癌的癌前病变,反映了宫颈癌的连续发展过程。
从宫颈癌前病变发展成宫颈癌,是一个较长时间的渐进性病理过程。
CIN有可能发展为宫颈癌,也有可能自发消退或逆转[6]。
宫颈癌是由HPV感染引起的,是一种感染性疾病。
生殖道HPV在有性活动的人群中普遍存在,每一名妇女在一生中都有可能接触到HPV的一种或多种亚型,大多数HPV的感染是暂时性的。
国外一项研究观察到,608例女大学生中HPV的感染率为43%,其中90%以上感染在2年内自然消退,仅有不足5%的人发展为CIN[7-9]。
从HPV携带者发展到CIN甚至宫颈癌还依赖其他因素的共同作用。
国际肿瘤研究机构多中心的研究资料表明,多次妊娠可能会增加HPV阳性妇女患CIN及宫颈癌的风险。
