BACKGROUNDEarly diagnosis and timely treatment are important for improving therapeutic efficiency of prostate cancer. DNA array is a new bio-technology for disease diagnosis. This study was conducted to diagnose prostate cancer with cDNA macroarray and analysis gene expression profiles of some selective genes in prostate cancer.

METHODSTotal RNA was isolated from patients with prostate cancer and from normal people, and poly (A) RNA was further purified. Then it was analyzed for differentially expressed genes in prostate cancer and normal prostate by cDNA macroarray system.

RESULTSThere were different expressions in the nine prostate-associated specific genes in prostate cancer as compared with normal prostate, in which, 7 were significantly upregulated and 2 were down-regulated.

CONCLUSIONAs a diagnostic approach at molecular level, the cDNA macroarray is an effectively diagnostic method for prostate cancer.

OBJECTIVESTo evaluate the efficacy of intrameatal application of low dosage alprostadil (PGE1) cream (300 mcg) for the treatment of erectile dysfunction (ED).

METHODSA total of 43 ED patients were selected in the study based on the inclusion criteria. All of the patients signed informed consent forms and entered a 4-week open-label clinical study. A dosage of 300 mg PGE1 in 75 mg cream was applied intrameatally.

RESULTSThe results showed that the primary efficacy (IIEF Q3 + Q4) reached 70.73% after application of the cream. The successful intercourse rate was 86.41%. Based on the GAQ (global assessment Question); 73.17% of the patients were satisfied with their sexual life. At the same time, all of the secondary criteria supported the primary efficacy results. Two patients withdrew during the study period. Six patients (14.63%) had urethral pain or penile redness, which were mostly mild and transient.

CONCLUSIONSWith intrameatal low dosage (300 mcg PGE1) of the PGE1 cream can achieve an equivalent efficacy as that with the full dosage.

OBJECTIVETo explore the effect of prostatectomy on nocturia in patients with benign prostatic hyperplasia (BPH).

METHODSThe data of patients who had received prostatectomy for BPH between June 2006 and December 2007 were collected. Nocturia severity was assessed preoperatively and 3 to 6 months after prostatectomy by the number of nocturia events, the time from falling sleep to the first awakening to void (hours of undisturbed sleep, HUS), the score of the nocturia quality of life (N-QOL) questionnaire, the International Prostatic Symptom Score (IPSS) and the quality of life (QOL) score.

RESULTSOne hundred and twenty five cases were included. Of them, 73 patients finished the follow-up completely. There were 62 patients whose number of nocturia events before the operation was equal or more than 2. The data from these 62 patients were analyzed. Of them, 56 patients underwent transurethral resection of prostate, the remaining 11 patients suprapubic prostatectomy. Significant improvement (P < 0.01) was noted in all the following parameters after treatment: the number of nocturia events decreased from 4.2 ± 2.4 to 2.2 ± 1.0, HUS increased from (1.8 ± 0.7) h to (3.0 ± 1.4) h, N-QOL score raised from 30 ± 10 to 40 ± 7, IPSS decreased from 23 ± 5 to 8 ± 5, and QOL score fell down from 4.4 ± 0.7 to 1.5 ± 1.0.

CONCLUSIONThe prostatectomy can markedly improve the symptoms of nocturia, sleep and life quality in the BPH patients who accompanied with nocturia.
