膜式和沉降式宫颈液基细胞学制片方法的比较研究

目的 分析评价膜式和沉降式宫颈液基细胞学制片方法和质量,以寻求提高宫颈液基细胞学制片质量的方法.方法 对我院妇产科送检的液基细胞学标本310份行相关处理后加入原细胞保存液1倍体积的保存液,充分振荡后取一半标本保存液置入另一个干净的保存瓶中.2瓶标本保存液分别按照膜式和沉降式两种制片方法制作涂片,所有涂片均经95%乙醇固定后行改良巴氏染色,并于肉眼及光学显微镜下观察染色情况.结果 肉眼观察膜式法所制涂片细胞分布不均,涂片周围细胞较多或较厚,部分区域细胞缺如或过厚;沉降式法所制涂片细胞分布均匀,有时细胞较厚,偶见较大细胞团块沉积.光学显微镜下见膜式法制作的涂片背景干净,细胞分布不均匀,涂片周围细胞较多或重叠严重,部分区域细胞缺如或重叠较多,有些细胞固缩明显,红细胞或炎细胞污染较少,染色不鲜艳;沉降式法制作的涂片背景尚干净,细胞分布均匀,有时细胞层次较多,细胞固缩或重叠较少,偶有红细胞或炎细胞污染,染色鲜艳.结论 本研究中沉降式法制作宫颈液基细胞学涂片可控性较膜式法好,制片质量较高.

A Comparative Study of Two Methods of Smear-making: Membrane-Based and Sedimentation in Liquid-Based Cervical Cytology

Objective To analyze and evaluate the methods and quality of membrane-based and sedimentation for smear-making in liquid-based cervical cytology,and to find ways to improve the quality of smear-making in liquid-based cervical cytology.Methods 1 time volume of preservation solution was added into 310 specimens collected from the Obstetric and Gynecologic Department,and half of the samples solution were put into a clean bottle after full oscillation.The samples from two kinds of bottles were made into smears ...
