Influence of Chuanshentong Injection on Expression of Sex Hormone Receptor in Human Benign Prostatic Hyperplasia / 中药新药与临床药理

Objective: To investigate the mechanism of Chuanshentong injection (CJ) in treating benign prostatic hyperplasia (BPH). Methods: The expression of androgen receptor (AR), estrogen receptor (ER), progesterone receptor (PR) was examined with immunohistochemical technique in 49 cases of BPH. Among 49 cases, 18 served as control (group A), 21 failed in the treatment of CJ (group B) and 10 recurrent (group C) after CJ treatment. Results: As compared with Group A, the positive rate of ER expression (81 %vs 38.9 %, P
