Low-concentration hydrogen peroxide solution for continuous bladder irrigation after transurethral resection of the prostate / 中华男科学杂志

<p><b>Objective</b>To evaluate the effectiveness and safety of low-concentration hydrogen peroxide solution (HPS) for continuous bladder irrigation after transurethral resection of the prostate (TURP).</p><p><b>METHODS</b>We retrospectively analyzed the clinical data about 148 cases of benign prostatic hyperplasia (BPH) treated by TURP from January 2013 to January 2016. Seventy-six of the patients received postoperative continuous bladder irrigation with 0.15% HPS (group A) and the other 72 with normal saline (group B). We compared the two groups of patients in their postoperative hemoglobin (Hb) levels, duration of bladder irrigation, frequency of catheter blockage, time of catheterization, and length of hospital stay.</p><p><b>RESULTS</b>There were no statistically significant differences between the two groups of patients preoperatively in the prostate volume, International Prostate Symptoms Score, maximum urinary flow rate, postvoid residual urine, or levels of serum PSA and Hb (P > 0.05). At 48 hours after operation, a significantly less reduction was observed in the Hb level in group A than in group B (［3.38 ± 2.56］ vs ［7.29 ± 6.58］ g/L, P < 0.01). The patients of group A, in comparison with those of group B, also showed remarkably shorter duration of postoperative bladder irrigation (［32.57 ± 5.99］ vs ［46.10 ± 8.79］ h, P < 0.01), lower rate of catheter blockage (3.3% vs 11.8%, P < 0.01), shorter time of catheterization (［3.74 ± 0.79］ vs ［4.79 ± 0.93］ d, P < 0.01), and fewer days of postoperative hospital stay (［4.22 ± 0.81］ vs ［4.67 ± 0.88］ d, P < 0.01).</p><p><b>CONCLUSIONS</b>Low-concentration HPS for continuous bladder irrigation after TURP can reduce blood loss, catheter blockage, bladder irrigation duration, catheterization time, and hospital stay, and therefore deserves a wide clinical application.</p>

Efficacy and safety of Saw Palmetto Extract Capsules in the treatment of benign prostatic hyperplasia / 中华男科学杂志

<p><b>OBJECTIVE</b>To assess the efficacy and safety of Saw Palmetto Extract Capsules in the treatment of benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>We conducted a multi-centered open clinical study on 165 BPH patients treated with Saw Palmetto Extract Capsules at a dose of 160 mg qd for 12 weeks. At the baseline and after 6 and 12 weeks of medication, we compared the International Prostate Symptom Scores (IPSS), prostate volume, postvoid residual urine volume, urinary flow rate, quality of life scores (QOL), and adverse events between the two groups of patients.</p><p><b>RESULTS</b>Compared with the baseline, both IPSS and QOL were improved after 6 weeks of medication, and at 12 weeks, significant improvement was found in IPSS, QOL, urinary flow rate, and postvoid residual urine. Mild stomachache occurred in 1 case, which necessitated no treatment.</p><p><b>CONCLUSION</b>Saw Palmetto Extract Capsules were safe and effective for the treatment of BPH.</p>

Inhibition of stromal interaction molecule 1 and the expression of apoptosis-related proteins in prostate cancer PC-3 cells / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the effects of stromal interaction molecule 1 (STIM1) on the expression of apoptosis-related proteins in prostate cancer PC-3 cells.</p><p><b>METHODS</b>We transfected the lentivirus vector STIM1-pGCSIL-GFP carrying STIM shRNA into human hormone-independent prostate cancer PC-3 cells, and 3 days later observed the transfection efficiency by fluorescence microscopy. At 7 days after transfection, we determined the expression of STIM1 in the PC-3 cells by RT-PCR and Western blot and those of apoptosis-related proteins Bcl-2, Bax, survivin and activated Caspase-3 by Western blot.</p><p><b>RESULTS</b>At 3 days, inverted microscopy revealed a transfection efficiency of > 80%. At 7 days, the STIM1 expression was significantly inhibited at both mRNA and protein levels. The Bcl-2/Bax rate was remarkably decreased as compared with that of the control group (0. 31 vs 1.24 ) , and the survivin expression was markedly reduced, 0. 14 times that of the relative expression in the control. However, the Caspase-3 cleavage was significantly activated, 1.52 times that of the control (P <0.05).</p><p><b>CONCLUSION</b>STIM1 can be regarded as an oncogene in prostate cancer PC-3 cells. Inhibition of its expression can induce PC-3 cell apoptosis by reducing the Bcl-2/Bax rate, decreasing the survivin expression, and activating the Caspase-3 pathway.</p>

Evaluation of 80-W and 120-W GreenLight laser vaporization for benign prostatic hyperplasia in high-risk patients / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate and compare the effectiveness and safety of 80-W GreenLight laser vaporization and GreenLight high-performance system (HPS) 120-W laser vaporization for the treatment of benign prostatic hyperplasia (BPH) in high-risk patients.</p><p><b>METHODS</b>We allocated 290 high-risk patients with BPH to two groups to receive 80-W (n = 220) and HPS 120-W GreenLight laser vaporization (n = 70). We recorded and compared the pre-, intra- and post-operative clinical data of the two groups.</p><p><b>RESULTS</b>The operations were successful in both of the groups. There were statistically significant differences in the prostate volume, IPSS, Qmax and PVR before and after surgery (P < 0.01), but not between the two groups (P > 0.05). The operation time, lasing time and energy consumption were (56.5 +/- 22.6) min, (31.2 +/- 10.3) min and (159.8 +/- 29.0) kJ in the 80-W group, as compared with (45.1 +/- 20.4) min, (24.6 +/- 8.3) min and (134.2 +/- 23.3) kJ in the 120 W group, with significant differences between the two (P < 0.01).</p><p><b>CONCLUSION</b>GreenLight laser vaporization of the prostate is a safe and effective procedure for the treatment of BPH, and the new HPS 120-W laser therapy, with its advantages of easier operation and shorter surgical time, is an even better minimally invasive option for elderly high-risk patients.</p>

Expressions of transforming growth factor-beta1, desmin and CD34 in the penile corpus cavernosum of rats / 中华男科学杂志

<p><b>OBJECTIVE</b>To detect the expressions of transforming growth factor-beta1 (TGF-beta1), Desmin and CD34 in the penile corpus cavernosum of SD rats in different age groups.</p><p><b>METHODS</b>We randomly selected 10 SD rats in each of the 2-, 5- and 20-month age groups, harvested their penile corpus cavernosum tissues under ether anesthesia, and detected the mRNA and protein expressions of TGF-beta1, Desmin and CD34 by RT-PCR and immunohistochemistry.</p><p><b>RESULTS</b>The results of RT-PCR showed the mRNA expressions of TGF-beta1, Desmin and CD34 in the corpus cavernosum tissues, with significant differences between every two groups (P < 0.01). The TGF-beta1 protein was mainly expressed in the trabeculae and around the arteries of the corpus cavernosum for membrane and cytoplasm staining, the Desmin protein mainly in the membrane and cytoplasm for muscle tissue staining; and the CD34 protein mainly in the vascular and sinusoidal endothelia. The mRNA expression of TGF-beta1 was correlated positively (r = 0.944, P < 0.01) while those of Desmin and CD34 negatively with the age of the rats (r = -0.947, P < 0.01; r = -0.934, P < 0.01). And the mRNA expressions of both Desmin and CD34 had a significant correlation with that of TGF-beta1 (r = -0.888, P < 0.01; r = -0.887, P < 0.01).</p><p><b>CONCLUSION</b>With the increase of age, the expression of TGF-beta1 is significantly up-regulated, while those of Desmin and CD34 significantly down-regulated in the corpus cavernosum tissues, and it is negatively correlated with the latter two. TGF-beta1 is an important influencing factor on ED.</p>
