ABSTRACT
This study aimed to assess the association between psychological disorders and erectile dysfunction (ED) in patients with different degrees of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). This was a retrospective study conducted from June 2017 to October 2019 and included 182 outpatients. Patients were interviewed using the Structured Interview on Erectile Dysfunction (SIEDY) for pathogenic quantification. The National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Index of Erectile Function-5 (IIEF-5) were used for the evaluation of CP/CPPS and ED. The Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) were used to assess anxiety symptoms and depressive symptoms. The number of patients with mild CP/CPPS and mild ED, mild CP/CPPS and moderate-to-severe ED, moderate-to-severe CP/CPPS and mild ED, and moderate-to-severe CP/CPPS and moderate-to-severe ED was 69 (37.9%), 36 (19.8%), 35 (19.2%), and 42 (23.1%), respectively. The corresponding PHQ-9 scores of the four groups were 6.22, 7.19, 10.69, and 7.71, respectively. The corresponding GAD-7 scores of the four groups were 5.26, 6.31, 8.77, and 6.36, respectively. Among patients with moderate-to-severe CP/CPPS, the PHQ-9 and GAD-7 scores of the moderate-to-severe ED group were significantly lower than those of the mild ED group (P = 0.007 and P = 0.010, respectively). The prevalence of ED and premature ejaculation (PE) in patients with moderate-to-severe CP/CPPS was significantly higher than that in patients with mild CP/CPPS (P = 0.001 and P = 0.024, respectively). Our findings proved that the severity of ED was negatively associated with psychological symptoms in outpatients with moderate-to-severe CP/CPPS.
ABSTRACT
AIM:To investigate the effect of microRNA(miR)-153-targeted positive regulatory domain zinc finger protein 2(PRDM2 )on invasion and migration abilities of bladder cancer cells through JAK /STAT signaling path-way.METHODS:The expression levels of miR-153 in bladder cancer tissues were detected by qPCR.The expression of PRDM2 in normal tissues and bladder cancer tissues was detected by immunohistochemistry.The effect of miR-153 on the transcriptional activity of PRDM2 was examined by dual-luciferase reporter assay system.The effect of miR-153 over-ex-pression on the invasion ability of bladder cancer RT 4 cells was detected by Transwell assay ,and the cell invasion ability was analyzed by scratch test.The protein levels of PRDM2,p-JAK2 and p-STAT3 were determined by Western blot.RE-SULTS:The expression of miR-153 was significantly lower in the bladder cancer tissues than that in normal tissues(P<0.05).PRDM2 was highly expressed in the bladder cancer tissue(P<0.05).The results of dual-luciferase reporter assay system showed that miR-153 regulated the expression of PRDM2.miR-153 over-expression significantly decreased the invasion and migration abilities of bladder cancer RT 4 cells.miR-153 over-expression also down-regulated the protein levels of p-JAK2 and p-STAT3(P<0.05).CONCLUSION:miR-153 targets PRDM2,and regulates the invasion and migra-tion abilities of bladder cancer cells by JAK/STAT signaling pathway.
ABSTRACT
Symptomatic seminal vesicle cysts (SVCs), especially those of a large size, can be removed by surgical treatments. Currently, open surgeries for SVC are rarely performed due to their extensive surgical trauma, and minimally invasive surgical therapies for treating seminal vesicle cysts are still in the early stages. In addition, relevant studies are mostly confined to case reports. In this study, we retrospectively reviewed 53 patients who had received transperitoneal laparoscopic unroofing or fenestration under seminal vesiculoscopy for SVC in our institution. Both surgeries decreased the cyst volume to a significant extent; however, according to the remnant lesion size after rechecking images, seminal vesiculoscopic fenestration tended to have a higher recurrence than laparoscopic unroofing. Regarding complications, two individuals in the laparoscopic unroofing group experienced ureteral injury and rectal injury, while patients in the fenestration group only had temporary hemospermia, which indicates that fenestration surgery tends to have less severe complications than laparoscopic unroofing. There was no solid evidence confirming semen improvement after these surgical therapies in our study. Future studies with a prospective design, larger sample size, and longer follow-up period are required to verify and further explore our findings.

<p><b>OBJECTIVE</b>To search for a new method of screening for molecular targets for androgen-dependent prostate cancer.</p><p><b>METHODS</b>We collected tissue samples and paired serum samples from 3 cases of androgen-dependent prostate cancer (ADPC) treated by surgical resection, and included another 3 samples of benign prostatic hyperplasia (BPH) tissue and normal human serum in the control group. The total proteins extracted were separated and transmembrane by two-dimensional gel electrophoresis, followed by hybridization with the sera of the patients with ADPC and those with hormone-independent prostate cancer (HIPC) as the primary antibodies. The differentially expressed proteins were compared by Western blot, analyzed by MALDI-TOF-MS mass spectrography, and verified by RT-PCR and Western blot following bioinformatic identification.</p><p><b>RESULTS</b>This modified method exhibited a significantly better effect in displaying differentially expressed proteins, by which 12 differentially expressed protein spots were identified, including Beclin1, glutathione S-transferase P (GSTP1-1), ZBTB7, dihydrodiol dehydrogenase 2 (DDH), enolase (ENO1), glucose-dependent insulin-releasing peptide receptor (GIPR), Mn-superoxide dismutase (MnSOD), phosphoglycerate mutase 1 (PGAM1), amino-peptidyl-prolyl cistrons isomerase (PPIA), and phospholipid-PE-binding protein (PEBP). The mRNA and protein expressions of Beclin1 were significantly down-regulated in androgen-dependent prostate cancer tissues.</p><p><b>CONCLUSION</b>This modified serum-guided immunoblotting technique has provided a new method for clarifying the molecular mechanisms of the occurrence and progression of HIPC, in which Beclin1-mediated autophagy may play a key role.</p>

OBJECTIVE@#To determine the expression of Smad4 and TGF-beta1 in bladder transitional cell carcinoma (BTCC), and to understand the mechanism of invasion, angiogenesis, and metastasis of BTCC.@*METHODS@#The expressions of Smad4 and TGF-beta1 in samples of 42 human bladder carcinoma and 12 normal bladder mucosa tissues were determined with standard immunohistochemical analysis. We also analyzed the relationship among the expressions of Smad4 and TGF-beta1 and invasion, angiogenesis, and metastasis of BTCC, and the correlation between Smad4 and TGF-beta1.@*RESULTS@#The positive rate of Smad4 in BTCC was significantly lower than those in normal bladder mucosa tissues (33.3% vs 83.3%, P < 0.01). The expressions of Smad4 in poorly differentiated, invasive, recurrent, or with lymph node metastasis of BTCCs were lower than those in well differentiated, superficial, nonrecurrent, or without lymph node metastasis ones (P <0.05). The positive rate of TGF-beta1 in BTCC was significantly lower than that in normal bladder mucosa tissues (64.3% vs 100%, P <0.01), which was positively correlated to that of Smad4 (P = 0.000).@*CONCLUSION@#The expressions of Smad4 and TGF-beta1 in BTCC decrease with the increase in clinical stage, poor pathological grade, and the recurrence and metastasis of BTCC.

OBJECTIVE@#To evaluate the therapeutic effect of harnal and proscar in treating benign prostatic hyperplasia (BPH).@*METHODS@#Two hundreds and twenty-two patients with BPH were randomly assigned into 2 groups:harnal (0.2 mg/d) group (n = 112) and proscar (5 mg/d) group (n = 108). American Urologic Association Symptom Index (AUA-SI) scores, the maximal urinary flow rate (Qmax) and prostatic volume were analyzed in the 2 groups.@*RESULTS@#After 12 weeks of treatment, 54.5% of the harnal group improved in AUA-SI score; 54.6% of the proscar group improved in AUA-SI score; and there was no significant difference between the 2 groups (P > 0.05). After 24 weeks of treatment, the proscar group (79.6%) had a greater improvement in AUA-SI score than the harnal group (64.3%) (P < 0.05); Qmax in the 2 groups was significantly increased than that before the treatment, and it is proportional to the therapeutic time. The prostatic volume in 2 groups had no significant change.@*CONCLUSION@#Harnal and proscar can significantly improve BPH symptoms and the urinary flow rate. The therapeutic effect of harnal and proscar has their own characteristics.

Objective To investigate the expression of Mta-1 in bladder transitional cell carcinoma (BTCC)and to analyze its correlation with the clinical staging,pathologic grading,metastasis and recur- rence,and to explore the possible molecular mechanisms.Methods Samples of 42 cases of BTCC and 12 normal bladder mueosa tissues were examined with immunohistochemical analysis for the expression of Mta- 1,ER,u-PA and PAI-1.Endothelial cells were stained by anti-CD34,and microvascular density(MVD)of carcinoma tissue was calculated.The correlation of Mta-1 expression with the invasion,metastasis,angiogene- sis and recurrence of BTCCs was analyzed;and the correlation of Mta-1 expression with ER,u-PA,PAI-1,and MVD was also analyzed.Results The positive rate of Mta-1 expression in BTCCs was 73.8%(31/42) , while it was 0.0% in normal bladder mucosa tissues(P<0.01).The expression level of Mta-l increased with the higher clinical stages and pathologic grades of BTCCs;it was higher in recurrence group(100.0% , 15/15)than in non-recurrence group(59.3%,16/27),and high in metastasis group(100.0%,14/14) than in non-metastasis group(60.7%,17/28)(P<0.05).The expression level of ER increased with the lower clinical stages and pathologic grades of BTCCs;the positive rate of ER expression was 0.0% in 14 ca- ses with metastasis and was 53.6% in 13 of 28 cases without metastasis(P<0.05);and the rate was 6.7% in 1 of 15 cases with recurrence and 44.4% in 12 of 27 cases without recurrence(P<0.05).Negative cor- relation was found between Mta-1 and ER expression(r=-0.739,P<0.01).The positive rate of u-PA ex- pression(59.5%,25/42)was significantly higher in BTCCs than that in normal bladder mucosa tissues (16.7%,2/12)(P<0.05).Positive correlation was found between u-PA and Mta-1 expression(r= 0.875),while negative correlation was found between u-PA and PAI-1 expression(r=-0.535).The posi- tive rate of PAI-1 expression in normal bladder mucosa tissues(50.0%,6/12)was significantly higher than that in BTCCs(19.0%,8/42)(P<0.05).In addition,negative correlation was found between PAI-1 and Mta-1 expression(r=-0.706).And positive correlation was found between MVD in BTCCs marked by an- ti-CD34 and Mta-1 expression(r=0.683).Conclusions Mta-1 is highly expressed in BTCCs,and it correlates closely with tumor pathologic grades,clinical stages,recurrence and metastasis.Mta-1 up-regulates the expression of u-PA and down-regulates that of PAI-1,which is associated with invasion and metastasis and acts as an angiogenic mediator in BTCCs.A negative correlation is found between Mta-1 and ER in inva- sion and metastasis of BTCCs.
