00 ± 18.25］ vs ［67.93 ± 15.89］ min, P less then 0.01), particularly in the patients with an interval of less then 2 weeks between HoLEP and TRPB than in those with an interval of ≥2 weeks (［91.17 ± 16.51］ vs ［68.13 ± 12.45］ min, P less then 0.01). Statistically significant differences were not found in the postoperative hemoglobin level, continuous bladder irrigation duration, catheter-indwelling time and hospital stay, nor in the incidence rate of transient urinary incontinence between the PB and NPB groups (47.62% vs 45%, P = 0.794). learn more There were no transurethral resection syndrome, bladder or rectal injury, or blood transfusion in either group, nor statistically significant differences in PVR, Qmax, IPSS and QOL score between the two groups of patients at 3, 6 or 12 months after operation. CONCLUSIONS HoLEP is a safe and effective surgical treatment of BPH for patients with a history of TRPB, which can reduce the time and increase the safety of operation when performed at ≥2 weeks after TRPB.Objective To investigate the effect of saw palmetto extract (SPE) on the reproductive function of rats with chronic prostatitis (CP). METHODS Forty male SD rats were equally randomized into groups A (blank control), B (blank control + SPE, C (CP model control) and D (CP model + SPE), and the CP model was made by injection of 1% λ-carrageenan solution into the prostate. The animals in groups A and C were gavaged with normal saline while those in groups B and D with SPE at 0.10 g/kg/d, all for 30 successive days. After drug withdrawal, the rats were mated with female ones in the ratio of 1∶1) and sacrificed 7 days later, their bilateral epididymides collected for detection of sperm count and motility. The numbers of pregnancies and fetuses were recorded and compared among different groups. RESULTS Compared with the rats in group A, those in group C showed a marked decrease in epididymal sperm motility (［68.01 ± 1.80］% vs ［62.59 ± 4.82］%, P 0.05). CONCLUSIONS SPE can improve the semen parameters of CP rats, and has no adverse effect on the rate of pregnancy and number of fetuses.Objective To investigate the influence of subchronic exposure to low-dose subchronic nano-nickel oxide (NNO) on the reproductive function of male rats and embryonic development of the pregnant rats. METHODS Fifty normal healthy male SD rats weighing 180－220 g were randomly divided into five groups of equal number, negative control, 4 mg/ml micro-nickel oxide (MNO), and 0.16, 0.8 and 4 mg/ml NNO, those of the latter four groups exposed to MNO or NNO by non-contact intratracheal instillation once every 3 days for 60 days, and then all mated with normal adult female rats in the ratio of 1∶2. After the female animals were confirmed to be pregnant, the males were sacrificed and the weights of the body, testis and epididymis obtained, followed by calculation of the visceral coefficients, determination of epididymal sperm concentration and viability and the nickel contents in the blood and semen by atomic fluorescence spectrometry. The female rats were killed on the 20th day of gestation for counting of the implanteckel level in the semen was correlated significantly with that in the blood (r = 0.912, P less then 0.01), negatively with the rate of viable sperm (r = －0.879, P less then 0.01) and positively with the percentage of morphologically abnormal sperm (r = －0.898, P less then 0.01). CONCLUSIONS Sixty-day exposure to nano-nickel oxide at 0.8 and 4 mg/ml can produce reproductive toxicity in male rats and result in fetal abnormality in the females, while that at 0.16 mg/ml has no significant toxic effect on the reproductive function of the males.Transurethral resection of the prostate (TURP) is a gold standard for the treatment of BPH. However, for large-volume BPH, TURP has its disadvantages of longer operation time, more residual glands, more intraoperative bleeding, lower efficiency, and longer hospital stay, which increase the risks of surgery and postoperative symptomatic recurrence. Therefore, minimally invasive treatment of large-volume BPH remains a clinical challenge. This paper focuses on the status quo and prospects of minimally invasive treatment of large-volume BPH, hoping to give some help with clinical practice.The prevention and control of human immunodeficiency virus (HIV) infection is important for public health. Sexual contact transmission has replaced blood transmission as a major route of HIV transmission in China. The incidence of HIV infection increased significantly among young men who have sex with men (MSM). Online social software instead of traditional venues has become a main means of seeking sexual partners. The application of online social software may contribute to an increased incidence of HIV among young MSMs by promoting such risky behaviors as having occasional or multiple sexual partners and drug abuse. Compared with the MSMs enrolled from traditional venues, those recruited online showed significant differences in the educational level, sexual behaviors, and HIV knowledge. Online social software is a promising way to improve the prevention and control of HIV as well as HIV-related epidemic surveys.ED is a common male disease, often caused by neurological, vascular or psychological factors, and the diagnostic methods for ED vary widely. The nocturnal penile tumescence test (NPT) by RigiScan is an objective assessment method used mainly to detect ED and has gained a wide clinical application in recent years. This review focuses on the application value of the six RigiScan parameters in the diagnosis of ED, namely, the number of erections, total erection time, event rigidity of tip/base, event tumescence of tip/base, tumescence activated unit and rigidity activated unit, aiming to provide some help to clinicians and researchers with the application of NPT.Objective To assess the clinical effects of transurethral holmium laser enucleation of the prostate (HoLEP) combined with Jisheng Shenqi Decoction (HoLEP + JSSD) on BPH. METHODS This study included 110 BPH patients treated in our hospital from August 2017 to April 2018, who were randomly assigned to receive HoLEP (n = 55) or HoLEP + JSSD (n = 55). We compared the pre- and post-operative IPSS, quality of life (QOL) score, prostate volume, postvoid residual urine volume (PVR), maximum urinary flow rate (Qmax), average urinary flow rate (Qavg) and levels of serum T, E2 and T/E2 as well as postoperative complications between the two groups of patients. RESULTS After treatment, both IPSS and QOL score were significantly lower in the HoLEP + JSSD than in the HoLEP group (P 0.05). CONCLUSIONS HoLEP + JSSD can significantly alleviate the lower urinary tract symptoms as well as improve the QOL and bladder and urinary tract functions of BPH patients.
