ABSTRACT
<p><b>OBJECTIVE</b>To determine the efficacy and safety of a diuretic agent, frusemide, combined with doxazosin in the treatment of nocturia in patients with benign prostate hyperplasia / lower urinary tract symptoms (BPH/LUTS).</p><p><b>METHODS</b>Sixty-four BPH/LUTS patients with nocturia were equally randomized into two groups, one treated with doxazosin (4 mg/d), and the other with frusemide (40 mg/d) and doxazosin (4 mg/d), given 6 h before sleep, both for 4 weeks. Urine volume, IPSS, QOL, serum electrolytes, plasma osmolality were recorded and compared between the two groups before and after the treatment.</p><p><b>RESULTS</b>Compared with the doxazosin group, the frusemide plus doxazosin group showed significantly reduced nocturia frequency (P < 0.01), increased daytime urine output (P < 0.01), decreased nocturia urine output (P < 0.01), unchanged total urine output (P > 0.05), improved IPSS and QOL (P < 0.05, P < 0.01), but with no remarkable differences in the levels of serum sodium, potassium, chlorine, and osmotic pressure (P > 0.05).</p><p><b>CONCLUSION</b>Four-week treatment with frusemide plus doxazosin was safe and effective for nocturia in patients with BPH/LUTS.</p>

<p><b>OBJECTIVE</b>To investigate the value of detection of AMACR (P504S), P63 and 34betaE12 cocktail in the early diagnosis of prostate cancer (PCa).</p><p><b>METHODS</b>The expressions of AMACR, P63 and 34betaE12 were examined in the biopsy specimens of 42 cases of prostate cancer, 12 cases of high-grade prostatic intraepithelial neoplasia (HGPIN) and 30 cases of benign prostatic hyperplasia (BPH) using the Maxvision single-step immunohistochemical method with triple-antibody cocktail (AMACR/P63/34betaE12) staining and double-color chromogens in single paraffin sections .</p><p><b>RESULTS</b>The expressions of AMACR, P63 and 34betaE12 were significantly different between PCa and BPH (P < 0.01). The staining of PCa was positive for AMACR and negative for P63 and 34betaE12, and the positivity rate of AMACR was 100%. BPH was strongly expressed for P63 and 34betaE12, but negatively for AMACR. The expression of AMACR was significantly different between HGPIN and BPH (P < 0.01), but not between HGPIN and PCa (P > 0.05), and the positivity rate of AMACR in HGPIN was 91.67%. However, the expressions of P63 and 34betaE12 were significantly different between HGPIN and PCa (P < 0.01), but not between HGPIN and BPH (P > 0.05), and the positivity rate of AMACR in HGPIN was 100%. The level of AMACR expression was not correlated with PCa Gleason score (P > 0.05).</p><p><b>CONCLUSION</b>AMACR is a sensitive and specific marker for PCa. P63 and 34betaE12 cocktail staining can increase the sensitivity and specificity of the basal cell detection. The immunohistochemical analysis with triple-antibody cocktail (AMACR/P63/34betaE12) staining and double-color chromogens can improve diagnostic accuracy and has an important applied value for the early diagnosis of prostate cancer.</p>
