To investigate the clinical effect of transurethral enucleation and resection of the prostate (TUERP) versus that of transurethral resection of the prostate (TURP) in the treatment of high-risk BPH.From June 2018 to December 2018, a total of 60 patients with high-risk BPH were randomly assigned to receive TUERP (n = 30) or TURP (n = 30). Comparisons were made between the two groups of patients in the operation time, intraoperative blood loss, volume of the resected prostate, and postoperative complications.Compared with the patients treated by TURP, those in the TUERP group showed a significantly shorter operation time(［76.2±15.9］ min vs ［47.5±16.1］ min, P0.05), less intraoperative blood loss(［93.7±33.6 vs ［60.5±25.4］ ml］ ml, P0.05), but a larger volume of the resected prostate(［30.6±8.5］ g vs ［42.3±12.2］ g, P0.05)， and a less incidence of postoperative complications, such as secondary bleeding, uracratia and urethrostenosis.Both TUERP and TURP are clinically effective for the treatment of high-risk BPH, but TUERP is even better than TURP for its advantages of shorter operation time, less intraoperative blood loss, larger volume of resected prostate, fewer postoperative complications, and less surgical trauma.

Renal cell carcinoma (RCC) is a primary malignant kidney cancer subtype. It has been suggested that long non‑coding RNAs (lncRNAs) serve important roles in the progression of kidney cancer. In fact, the lncRNA small nucleolar RNA host gene 12 (SNHG12) was discovered to be overexpressed in various types of cancer. However, to the best of our knowledge, the role of SNHG12 in RCC remains unclear. The present study aimed to investigate the function of SNHG12 and its underlying molecular mechanism of action in RCC. In patient samples and datasets from The Cancer Genome Atlas. Reverse transcription‑quantitative PCR, demonstrated that SNHG12 expression levels were upregulated in RCC tumor tissues, but not in normal kidney tissues. SNHG12 upregulation was also observed in RCC cell lines. Kaplan‑Meier survival analysis indicated a poor prognosis for those patients with RCC who had upregulated SNHG12 expression levels. Following lentivirus transduction, SNHG12 was successfully knocked down (validated by western blot analysis) and cell migration and invasion assays were performed. SNHG12 knockdown markedly inhibited cell viability and invasion, while increasing apoptosis in both A498 and 786O cell lines. The results of the luciferase reporter assay suggested that SNHG12 exerted its role by sponging microRNA (miR)‑200c‑5p, which led to the upregulation of its target gene, collagen type XI α1 chain (COL11A1). This was further validated, as miR‑200c‑5p inhibition reduced the effects of SNHG12 downregulation on cell viability and apoptosis, without affecting SNHG12 expression levels. Furthermore, the findings indicated that SNHG12 may partially exert its role through COL11A1, which was also upregulated in RCC. In conclusion, the results of the present study suggested that the SNHG12/miR‑200c‑5p/COL11A1 axis may be crucial for RCC progression, which provided an insight into potential therapeutic strategies for RCC treatment.

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder of unclear etiology, which commonly presented with the enlargement of lymph nodes of the neck and the head. Here, we report an unusual case of 77-year-old male patient presenting with left kidney lesion with several small enlarged lymph nodes around the abdominal aorta. The diagnosis of left kidney cancer was suspected and the patient underwent left laparoscopic exploration and lymph node biopsy. Only saponification of the renal surrounding fat and enlargement of the left renal pedicle and 5 abdominal aortic lymph nodes were found; no kidney cancer was found. Surrenalectomy and lymphadenectomy dissection were then performed and the left kidney was retained. Intraoperative frozen and postoperative pathology indicates Rosai-Dorfman disease. RDD with kidney involvement is uncommon, and its x-ray imaging appearances are atypical, and often resemble kidney cancer leading to kidney loss. A systematic literature review was also performed to investigate the x-ray imaging and treatment features of this disease.

Objective To investigate the effect of transforming growth factor-β1 (TGF-β1) on the expression of Fascin1 protein and its impact on cell invasion and metastasis in human renal carcinoma. Methods Renal tissue slices of 52 cases when undergoing radical nephrectomy were collected to be the observation group, and the normal renal tissues of 23 cases when undergoing nephrectomy due to trauma were collected to be the control group. The expressions of TGF-β1 and Fascin1 were measured by immunohistochemical staining. Human renal carcinoma 786-0 cell line was selected as the study subject. The cells were divided into six groups including NT (no transfection), si-NC (transfection with pGenesil-1-con) si-Fascin1 (transfection with pGen-1-FSCN1) groups, and three corresponding groups: NT, si-NC and si-Fascin1 groups treated with TGF-β1. RT-qPCR, Western-Blot, Transwell, and flow cytometry method were used in this study. Results The expressions of TGF-β1 and Fascin1 in the observation group were significantly higher than those in the control group. The expression of TGF-β1 was positively correlated with that of Fascin1. After 24 and 48 h of treatment with TGF-β1 (10 ng/mL), the invasive and metastatic abilities of the 786-0 cells in the NT and si-NC groups were higher than those before the treatment (P

OBJECTIVE To evaluate the effects of microRNA-21 (miR-21) in peripheral blood mononuclear cells (PBMC) in the diagnosis and prognosis of prostate cancer (PCa). METHODS Proved by pathologic biopsy, 92 patients diagnosed with PCa and also underwent resection operation and 85 patients with benign prostatic hyperplasia (BPH) were selected in this study, as well as 97 healthy volunteers were chosen as the control group. PBMC were extracted to examine the relative expression of miR-21 by real time reverse transcriptase-polymerase chain reaction (RT-PCR). The relative operating characteristic (ROC) curves were drew to analyze the diagnosis value of PCa. The survival function curves were made by Kaplan-Meier method to show the miR-21 expression levels of PCa patients. The Log-rank test was adopted to compare the differences among the different groups. The Cox proportional hazard risk regression analysis was used to screen the independent factors affected the PCa patients. RESULTS The expression levels of miR-21 in PCa group were increased compared to BPH and control group (P < 0.05). The expression of miR-21 was significantly correlated with the Gleason score, clinical stages, bone metastasis and tumor recurrence (all P < 0.05). ROC curves demonstrated that the area under the curve of PCa and BPH distinguished by the miR-21 were 0.974 and 95% confidence intervals (95% CI) were 0.956∼ 0.993. The sensitivity and specificity were 93.5% and 92.9%. ROC curves demonstrated that the area under the curve of PCa and control group distinguished by the miR-21 were 0.984 and 95% CI were 0.972∼ 0.997. The sensitivity and specificity were 94.6% and 92.8%. The results of Kaplan-Meier Method demonstrated that the miR-21 expression levels were related to the prognosis of PCa (all P < 0.05). The results of the COX analysis suggested that the miR-21 expression level, tumor recurrence and bone metastasis could be the independent factors affected the prognosis of PCa patients (all P < 0.05). CONCLUSION miR-21 is highly expressed in the PCa patients, which could be the molecule biomarker of diagnosis and prognosis of PCa.

Objective The study is performed to explore the correlations of forkhead box O3 (FoxO3) and forkhead box O4 (FoxO4) expressions with clinicopathological features and prognosis of bladder cancer. Methods Bladder cancer tissues and adjacent normal tissues from the recruited 222 patients were collected. Quantitative real-time polymerase chain reaction (qRT-PCR), Western blotting and immunohistochemistry were applied to determine the expressions of FoxO3 and FoxO4. Spearman correlation analysis was conducted to examine the correlation between the expressions of FoxO3 and FoxO4. All patients were followed up and overall survival (OS) and disease-free survival (DFS) were recorded. Kaplan-Meier survival curve was drawn to determine the associations of FoxO3 and FoxO4 expressions and postoperative survival. Cox proportional hazards model was conducted to analyze the risk factors for poor prognosis of bladder cancer. Results The mRNA and expressions of FoxO3 and FoxO4 proteins in the bladder cancer tissues were lower than that in the adjacent normal tissues (both P 0.05). The positive rates of FoxO3 and FoxO4 were lower in the patients with lymph node metastasis than that in the patients without lymph node metastasis ( P 0.05), and significantly lower in the patients with non-muscle invasive bladder cancer (T is -T 1 ) than in those with non-muscle invasive bladder cancer (T 2 -T 3 ) in TNM staging, and remarkably lower in the patients with high grade than in those with low grade in the histological type ( P 0.05). Furthermore, the expressions of FoxO3 and FoxO4 were positively correlated in the bladder cancer tissues ( P Conclusions The FoxO3 and FoxO4 expressions may potentially associate with the clinicopathological features and prognosis of bladder cancer.

To explore the optimal methods for the reconstruction and preservation of the glans after partial penis resection in the treatment of early-stage penile cancer.Between January 2012 and June 2015, we treated 6 cases of early- stage penile cancer by partial penis resection, inner thigh skin graft, and glans reconstruction and followed them up for 0.5-3 years.The length of the penis before and after operation was ([6.5 ± 1.2] vs [4.5 ± 1.8] cm) in the flaccid state and ([12.8 ± 2.3] vs [9.1 ± 2.1] cm) in the erectile state. The sense of the reconstructed glans was completely recovered at 3 months after surgery. The glans skin was pale red and soft, nearly normal at 12 months, with no obvious graft contracture or scar formation. All the patients achieved normal erection and their partners were satisfied with their intercourse. No recurrence or metastasis was observed.The strategy of partial penis resection, inner thigh skin graft and glans reconstruction, simple, effective, and with few complications, is one of the best treatments of early-stage penile cancer, which not only ensures radical removal of the tumor but also maximally reserves the function of the organ.

The present study investigated the potential association between matrix metalloproteinase-9 (MMP-9) expression and the pathogenesis of bladder cancer. The present study reviewed previous studies published in Chinese and English using predefined selection criteria, which identified high-quality studies concerning MMP-9 and bladder cancer. Statistical analyses of the data were conducted using Comprehensive Meta-Analysis software version 2.0. In total, 23 case-control studies were selected, which consisted of 1,040 bladder cancer patients and 244 healthy controls. The expression rates and protein levels of MMP-9 were significantly increased in bladder cancer patients compared with the healthy controls, which was demonstrated using immunohistochemistry (IHC) and enzyme-linked immunosorbent assay-based methods. Furthermore, the expression rate of MMP-9 in histological G1/G2 grade bladder cancer tumors was significantly decreased compared with G3 tumors. Subgroup analysis based on ethnicity demonstrated that the rate of MMP-9 protein expression between bladder cancer patients and healthy controls was significantly different in African, Asian and Caucasian patients, which was identified using IHC. The MMP-9 protein levels in bladder cancer patients and healthy controls were significantly different between Asian and Caucasian patients, but not African patients. The differences between MMP-9 expression in ethnic groups were also evident in the expression rate of MMP-9 identified in histological G1/G2 grade tumors in Asian and Caucasian patients compared with G3 grade tumors, which was not evident in African patients. In conclusion, the present meta-analysis results markedly indicate that MMP-9 expression is associated with clinicopathological features of bladder cancer, suggesting that MMP-9 may be a useful biomarker in the diagnosis and clinical management of bladder cancer, and may be a valuable therapeutic target.

Our study aimed to evaluate the diagnostic and prognostic values of microRNA-21 (miR-21) expression levels in peripheral blood mononuclear cells (PBMCs) for prostate cancer (PCa).Between February 2010 and June 2014, 75 consecutive patients with localized PCa confirmed by radical prostatectomy and biopsy were enrolled as the case group. Among them, 25 patients were confirmed with recurrence or metastasis (R/M) (PCa with R/M group) and 50 patients without R/M (PCa without R/M group). During the same period, 75 healthy volunteers were enrolled as the control group. Blood was collected from all subjects, and PBMCs were isolated. Relative miR-21 expression levels from the PBMCs were determined by fluorescence real-time quantitative polymerase chain reaction (RT-qPCR).The relative miR-21 expression levels in the preoperative case group was significantly higher than that in the postoperative case group and the control group (both p0.001). miR-21 expression levels were associated with tumor differentiation, clinical stage, and lymph node metastasis (all p0.001). Furthermore, miR-21 expression levels in PCa patients with R/M were significantly higher than that in PCa patients without R/M and healthy controls (both p0.001). Receiver operating characteristic (ROC) curve analysis revealed that the cut-off point of miR-21 for diagnosis of PCa was 0.9 with a sensitivity of 87.5% and a specificity of 85.7%.Our study demonstrates that high miR-21 expression levels in PBMCs were correlated with the presence, recurrence, and metastasis of PCa and that this may be a useful biomarker for screening PCa and monitoring the risk of PCa recurrence and metastasis.

Prostate cancer (PCa) remains the second leading cause of cancer diagnosis worldwide. Early diagnosis and treatment of PCa is critical since the long-term prognosis is excellent in patients with tumors confined to the prostate gland. The current meta-analysis investigates the diagnostic value of resistive index (RI) measurement using color Doppler ultrasound in patients with PCa. Electronic literature databases were exhaustively searched for relevant studies published prior to May 31, 2014. Nine studies met our predetermined inclusion criteria for the present meta-analysis. The methodologic quality of the selected studies was independently assessed by 2 reviewers based on Quality Assessment of Diagnostic Accuracy Studies tool. Our meta-analysis results showed that RI values were significantly higher in malignant prostate tissues compared to normal prostate tissues (standardized mean difference [SMD] 0.42, 95% confidence interval [CI] 0.12~0.73, p = 0.007) and benign prostate tissues (SMD 0.41, 95% CI 0.26~0.56, p

To explore multi-drug resistance (MDR) of bladder cancer for the intravesical instillation.Using immunohistochemical staining, in 44-case human bladder cancer cells, the expressions of P-glycoprotein (P-gp), glutathione S-transferase (GST-pi) and topoisomerase (TOPO-II), were detected to find out the resistance to drugs.P-gp had a higher expression in 54.5% cases. GST-pi had no or a lower expression in 65.9% cases. TOPO-II had a higher expression in 29.5% but a lower expression in 65.9% cases.Detecting the factors of MDR in bladder cancer cells could help to choose drugs for intravesical chemotherapy.

The incidence of varicocele in older adolescence varies from 12.4% to 17.8% with an average of 14.7%, similar to the incidence in adult males. Varicocele is associated with testicular growth arrest in adolescents. Varicocelectomy can reverse the testicular growth arrest. But without the testicular growth arrest, prophylactic surgery for every adolescent with varicocele is not advised. Surgery treatment should be offered to: 1. adolescents with testicular growth arrest more than 2 ml of difference between left and right testicle, 2. adolescents with abnormal semen analysis with high-grade varicocele, 3. adolescents with symptoms: pain, heaviness, swelling, 4. adolescents with bilateral varicoceles. Recurrence of the varicocele after surgery treatment can occur in 9% to 16% of adolescents. But rate of recurrence can be kept below 2% in adolescents treated by high retroperitoneal ligation with testicular artery ligation.
