利用免疫组织化学ＬＳＡＢ法，观察了５１例子宫颈鳞状细胞癌中ｂｃｌ２和ｂａｘ基因产物的表达，以探讨ｂｃｌ２和ｂａｘ与该肿瘤临床病理特征及患者预后的关系。结果表明，５１例子宫颈鳞癌中，４３１３％（２２／５１）ｂｃｌ２产物阳性，５２９４％（２７／５１）ｂａｘ产物阳性。在分化程度高、无淋巴结转移患者中，ｂｃｌ２高表达。在临床分期晚、分化程度低、有淋巴结转移患者中，ｂａｘ高表达。ｂｃｌ２和ｂａｘ表达间呈负相关。提示ｂｃｌ２和ｂａｘ基因蛋白均参与了子宫颈鳞癌的发生发展过程，有着不同的生物学作用 The expression of bcl2 and bax gene in 51 cases of cervical squamous cell carcinoma was observed by immunohistochemistry LSAB method to explore the relationship between bcl2 and bax and the clinicopathological features and prognosis of the patients. The results showed that in 51 cases of cervical squamous cell carcinoma, 43.13% (22/51) were positive for bcl-2 and 52.94% (27/51) for bax. In a high degree of differentiation, no lymph node metastasis, bcl  2 expression. Late in the clinical stage, low differentiation, patients with lymph node metastasis, bax high expression. bcl  2 and bax expression was negatively correlated. Tip bcl  2 and bax gene proteins are involved in the development of cervical squamous cell carcinoma has a different biological role
