OBJECTIVE: To detect the expression of Ki-67, Bcl-2, Bax and caspase-3 in simple benign prostatic hyperplasia (BPH) and BPH combined with prostatitis,and to evaluate the effect of inflammation on the development and progression of BPH.
METHODS: All specimens were obtained from patients undergoing surgical resection of the prostate. The paraffin section of the specimens was stained with hemotoxyline and eosin, and observed under light microscope to examine the inflammation hispathological changes. Sixteen patients with simple BPH (Group A) and 42 patients with BPH combined with prostatitis (Group B) were included. Immunohistochemical analysis and Western blot were used to examine the expression of Ki-67, Bcl-2, Bax and caspase-3.
RESULTS: The expression of Ki-67 and Bcl-2 was significantly higher in Group B than that in Group A (P<0.05), and caspase-3 expression was significantly lower (P<0.05). There was no difference in Bax expression between the 2 groups (P>0.05).
CONCLUSION: Prostatitis can up-regulate Ki-67, Bcl-2 expression, and down-regulate the expression of caspase-3 in BPH. Prostatitis appeared to play an important role in the development of BPH by affecting the proliferation and apoptosis of the prostatic cells.
