Prostate cancer is one of the most common malignant tumors in the male urinary system as well as the second leading cause of cancer death in men. Prostate specific antigen (PSA) screening is the main method for the early diagnosis of prostate cancer, but has a low specificity for its detection. In recent years, a variety of tumor markers with high sensitivity and specificity have been found. This review focuses on some of the more promising tumor biomarkers such as prostate cancer antigen 3, early prostate cancer antigen, prostate-specific membrane antigen, alpha-methylacyl-CoA racemase, and vascular endothelial growth factor.

Dapoxetine for premature ejaculation: Advances in clinical studies.

Ting-you ZHOU ; Yan-feng LI

National Journal of Andrology.2015;21(10):931-936.

Premature ejaculation (PE) is a most common sexual dysfunction, for which dapoxetine, a novel selective serotonin (5-HT) re-uptake inhibitor (SSRI), is the only licensed oral medicine at present. With the advantages of fast absorption, rapid action, on-demand medication, and short half-life time, dapoxetine has been proved by clinical trials to be effective in prolonging the intravaginal ejaculation latency time (IELT) and improving the overall condition of PE patients in various areas and populations. Compared with the traditional SSRIs, dapoxetine has a better safety and tolerability. The most frequently reported dapoxetine-related adverse events include nausea, diarrhea, headache and dizziness, but with very few severe or serious cases.

Fang FANG ; Ke NI ; Cheng-liang XIONG

National Journal of Andrology.2015;21(10):925-930.

Spermatogenesis is a complex process. Current knowledge about human spermatogenesis is mainly based on the mouse model while little is known about the initial stage of this fundamental process in humans. The establishment of the model of spermatogenesis in vitro may contribute to an overall understanding of male germ cell development, an insight into the mechanisms of infertility, and clinical management of male infertility. This review summarizes current knowledge about the generation of germ cell-like cells from induced pluripotent stem cells (iPSCs) in vitro and discusses the potential application of iPSCs in the treatment of male infertility.

National Journal of Andrology.2015;21(10):921-924.

OBJECTIVETo investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).

METHODSTotally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.

RESULTSOne patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).

CONCLUSIONOral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.

National Journal of Andrology.2015;21(10):917-920.

OBJECTIVETo investigate the characteristics, diagnosis, and treatment of ovotesticular disorder of sex development (OT-DSD).

METHODSWe retrospectively analyzed 2 cases of OT-DSD treated in our hospital. The patients were 19 and 15 years old, respectively, and both received systematic physical examination and examinations of the karyotype, sex hormone, adrenocorticotropic hormone (ACTH), color Doppler ultrasonography, urethrocystoscopy, and human chorionic gonadotropin (HCG) test. Under the laparoscope, we performed surgical gonad exploration, gonadectomy, and vulvar orthopedics. Intraoperative exploration and pathology confirmed true hermaphroditism in both cases, with sex selection as female. One underwent laparoscopic resection of the ovotestis, and the other removal of the testis with the ovarian tissue reserved.

RESULTSThe patients were followed up for 12 months postoperatively, which found no abnormality in either the vulvas or the genital glands.

CONCLUSIONSurgical exploration of the gonad is the only method for the diagnosis of OT-DSD and sex selection is the key to treatment. Laparoscopic surgical exploration of the gonad and vulvar orthopedics are the first treatment options.

National Journal of Andrology.2015;21(10):913-916.

OBJECTIVETo investigate the correlation of the fertilization strategy and embryo transfer (ET) time with the incidence of ectopic pregnancy.

METHODSWe selected 3,331 fresh and 2,706 frozen-thawed ET cycles for the patients undergoing in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). The fresh transfers included 2 546 IVF-ET and 785 ICSI-ET cycles and 2,220 day-3 embryo and 1,111 day-5 blastocyst transfers, while the frozen-thawed transfers included 2,080 IVF-ET and 626 ICSI-ET cycles and 741 day-3 embryo and 1 965 day-5 or -6 blastocyst transfers. We compared the incidence rate of ectopic pregnancy associated with different fertilization strategies and ET time.

RESULTSThe incidence rate of ectopic pregnancy was 1. 41% (36/2 546) in the IVF-ET cycles and 3.44% (27/785) in the ICSI-ET cycles of the fresh transfers, significantly lower in the IVF-ET than in the ICSI-ET cycles (P < 0.01), and it was 1.01% (21/2,080) in the IVF-ET cycles and 0.80% (5/626) in the ICSI-ET cycles of the frozen-thawed transfers, with no remarkable difference between the two groups (P > 0.05). The IVF-ET and ICSI-ET cycles included 2,220 fresh day-3 (F-D3) embryos, 1,111 F-D5 blastocysts, 741 frozen-thawed day-3 (T-D3) embryos, and 1,965 T-D5/6 blastocysts. The incidence rate of ectopic pregnancy was 1.71% (n = 38) in the F-D3, 2.25% (n = 25) in the F-D5, 1.35% (n = 10) in the T-D3, and 0.81% (n = 16) in the T-D5/6 group, respectively, significantly lower in the T-D5/6 than in the other three groups (P < 0.05).

CONCLUSIONThe incidence rate of ectopic pregnancy is associated with fertilization strategies, which is significantly lower in frozen-thawed than in fresh embryo transfers.

National Journal of Andrology.2015;21(10):908-912.

OBJECTIVETo explore the clinical application value of Provider-Initiated HIV Testing and Counseling (PITC) by analyzing the positive rate of HIV tests for people in need of PITC and that of routine HIV tests.

METHODSWe retrospectively analyzed the demographic and epidemiologic data about the patients seeking PITC services or undergoing routine HIV tests in Nanjing Drum Tower Hospital between January and December 2013.

RESULTSThe positive rate of initial HIV screening was 1.98% in the PITC group and 0.24% in the routine test group, while that of confirmed HIV was 0. 40% in the former and 0.07% in the latter, both with statistically significant differences between the two groups (P < 0.01). The positive rate of HIV was markedly higher in males than in females, particularly in the PITC group.

CONCLUSIONPITC has a high clinical value in HIV detection for targeted subjects and therefore deserves general application in dermatology.

OBJECTIVETo compare the outcomes and complications of 3D versus 2D laparoscopic radical prostatectomy ( LRP) in the treatment of prostate cancer.

METHODSWe retrospectively reviewed 18 cases of prostate cancer treated by 3D LRP and another 32 by 2D LRP. We compared the general data, intraoperative blood loss, postoperative drainage time and hospital stay, Gleason scores, and incidence of complications between the two groups of patients.

RESULTSAll the operations were successful and none was transferred to open surgery. The two groups of patients were similar in terms of age, body mass index, Gleason scores, and clinical stages. However, compared with the 2D LRP group, the 3D LRP group showed significantly shorter operation time ([180.2 ± 69.1] vs [118.3 ± 55.1] min, P < 0.01), less blood loss ([236.5 ± 60.6] vs [89.1 ± 35.2] ml, P < 0.01), less postoperative drainage time ([7.1 ± 1.1] vs [5.3 ± 2.1] d, P < 0.01), shorter postoperative hospital stay ([20.2 ± 5.5] vs [14.4 ± 7.2] d, P < 0.01), and lower incidence of perioperative complications (3.1% vs 0, P < 0.01). The incisal margin was pathologically negative in both groups and urinary incontinence was found in neither at 6 months after surgery (P > 0.05).

CONCLUSION3D LRP, with its advantages of shorter operative time, faster recovery, and better outcomes than 2D LRP in the treatment of prostate cancer, deserves general application in lower-level hospitals.

National Journal of Andrology.2015;21(10):900-903.

OBJECTIVETo explore the efficacy and safety of prostatic arterial embolization (PAE) in the treatment of benign prostatic hyperplasia ( BPH) in high-risk aged males.

METHODSWe retrospectively analyzed the clinical data about 21 high-risk BPH patients aged 77-91 (mean 80) years treated by PAE.

RESULTSPAE was successfully performed in all the 21 patients, with the operation time of 90-120 min. At 2 weeks, 3 months, 6 months, and 12 months after surgery, the International Prostate Symptom Scores (IPSS) were 18.3 ± 3.1, 9.8 ± 2.7, 9.4 ± 2.5, and 10.1 ± 2.2, the quality of life scores ( QOL) were 4.6 ± 1.4, 4.3 ± 1.2, 4.6 ± 1.1, and 4.9 ± 0.6, the maximum urinary flow rates ( Qmax) were (12.5 ± 2.5), (15.8 ± 2.4), (16.6 ± 2.2), and (16.3 ± 1.8) ml/s, and the postvoid residual urine volumes (PVR) were (35.0 ± 3.4), (13.0 ± 3.3), (10.0 ± 3.0), and (8.0 ± 2.5) ml, respectively, markedly improved as compared with the baseline (IPSS: 24.5 ± 3.7, QOL: 5.7 ± 1.6, Qmax: [8.3 ± 2.1] ml/s, and PVR: [98.0 ± 11.0] ml), with statistically significant differences in IPSS, QOL, Qmax, and PVR (all P < 0.05). The maximal velocity of blood flow in the prostate was obviously decreased and the prostate volumes were (74.4 ± 4.8), (42.5 ± 4.4), (38.3 ± 4.0), and (36.7 ± 3.5) cm3 at 2 weeks, 3 months, 6 months, and 12 months, respectively, also significantly reduced in comparison with (84.3 ± 5.4) cm3 preoperatively (all P < 0.05).

CONCLUSIONPAE is a safe and effective option for the treatment of BPH in high-risk aged males.

OBJECTIVETo investigate the feasibility and advantages of transurethral transumbilical laparoendoscopic single-site surgery (TU-LESS) for radical prostatectomy.

METHODSFive patients with prostate cancer underwent TU-LESS for radical prostatectomy, with a four-channel single-port device inserted into a 2. 5 cm periumbilical incision and another placed through the urethra, followed by analysis of the perioperative data.

RESULTSAll the operations were successfully accomplished, with neither conversion to open surgery nor additional channel. The mean operation time, intraoperative blood loss, and postoperative hospital stay were 168 min, 120 ml, and 15 d, respectively. No severe perioperative complications were observed. TNM stage classification manifested T2cN0M0 in 2 cases and T2bN0M0 in the other 3. Postoperative pathology showed no negative surgical margins in any of the cases.

CONCLUSIONTU-LESS is safe and feasible for radical prostatectomy and can reduce the complication of low urinary tract surgery by single-site laparoendoscopy.
