METHODS: MTT assay and immunohistochemical staining method were used to detect the activity of the proliferation and metabolic status of human bladder cancer BIU 87 cells and the expression of proliferating cell nuclear antigen ( PCNA) after the BPD MA were activated by laser.

方法采用亚甲基噻唑蓝（MTT）法和免疫组化染色法检测激光活化BPD-MA后人膀胱癌细胞株BIU-87细胞增殖代谢活性及增殖细胞核抗原（proliferating cell nuclear antigen，PCNA）的表达。

Integrally, the RISC CPU has BIU ( Bus Interfacing Unit), IDU ( Instruction Decoding Unit)-. ALU ( Arithmatic& logic Unit), MMU ( Memory Management Unit) etc.

从整体方面来说，整个微处理器大致分为BIU（总线接口单元）、IDU（指令译码单元）、ALU（算术逻辑单元）、MMU（存储管理单元）等等。

Results: The expression of Bcl 2 gene was strongly positive in BIU 87/ ADM cells but poorly positive in BIU 87 cells.

结果：BIU87/ADM细胞Bcl2基因表达呈强阳性（），BIU87细胞呈弱阳性（+）。

Results The expression of FasL in BIU 87 cells was positive.

结果膀胱癌细胞系BIU87FasL表达阳性。
