肿瘤细胞代谢功能比正常细胞高,同时肿瘤细胞表面钙价低,致密细胞凝集力低于正常细胞10倍以上,故肿瘤细胞比正常上皮细胞更易脱落,因此对脱落细胞提供了早期诊断创造了条件[1]。我们利用HE—pmb组织化学染色收集2010年6月~2012年12月2171例胸腹腔积液、细针穿刺,各种分 Tumor cells have higher metabolic function than normal cells, meanwhile the surface calcium of tumor cells is low, the density of dense cells is 10 times lower than that of normal cells, so the tumor cells are easier to fall off than the normal epithelial cells, thus providing the conditions for early diagnosis of exfoliated cells [1]. We used HE-pmb histochemical staining collected from June 2010 to December 2012 in 2171 cases of pleural effusion, fine needle aspiration, various points
