针吸细胞学诊断恶性肿瘤方法简单、迅速 ,病人容易接受 ,是诊断肿瘤的重要手段 ,但在日常病理工作中 ,对细胞涂片一般只做ＨＥ染色 ,这样 ,对有些肿瘤不能做出明确诊断 ,需进一步作免疫组织化学(ＩＨ)检查再行明确诊断。因此 ,我们选了 4类不同的化学试剂 ,分别对ＨＥ染色的涂 The needle aspiration cytology diagnosis of malignant tumors is simple, rapid, and easy for patients to accept. It is an important means for diagnosing tumors. However, in routine pathological work, smears of cells are generally only stained with HE, so that certain tumors cannot be diagnosed clearly. The need for further immunohistochemistry (IH) examination to confirm the diagnosis. Therefore, we selected 4 different chemical reagents, respectively, for HE staining.
