支气管刷取物(以下简称支刷)系机械性取材,细胞非自然脱落,故涂片中常见多种多样的裸核。由于它失去了胞浆外形,识别裸核自然比识别完整细胞困难得多。而正确地识别这些裸核对提高细胞学诊断的阳性率和准确性又颇为重要,现将我们的经验体会介绍如下。 The bronchial brush material (hereinafter referred to as brush) is mechanically drawn and the cells are unnaturally detached, so a wide variety of bare nuclei are common in smears. Because it loses its cytoplasmic profile, recognizing naked nuclei is naturally much more difficult than identifying intact cells. Accurately identifying these naked nuclei is important for improving the positive rate and accuracy of cytological diagnosis. Now we will introduce our experience as follows.
