Abstract
Erectile dysfunction (ED) is a common clinical condition that mainly affects men aged over 40 years. Various causes contribute to the progression of ED, including pelvic nerve injury, diabetes, metabolic syndrome, age, Peyronie's disease, smoking, and psychological disorders. Current treatments for ED are limited to symptom relief and do not address the root cause. Stem cells, with their powerful ability to proliferate and differentiate, are a promising approach for the treatment of male ED and are gradually gaining widespread attention. Current uses for treating ED have been studied primarily in experimental animals, with most studies observing improvements in erectile quality as well as improvements in erectile tissue. However, research on stem cell therapy for human ED is still limited. This article summarizes the recent literature on basic stem cell research on ED, including cavernous nerve injury, aging, diabetes, and sclerosing penile disease, and describes mechanisms of action and therapeutic effects of various stem cell therapies in experimental animals. Stem cells are also believed to interact with host tissue in a paracrine manner, and improved function can be supported through both implantation and paracrine factors. To date, stem cells have shown some preliminary promising results in animal and human models of ED.

Abstract
Bladder cancer, the most common malignant tumor in the urinary system, exhibits significantly up-regulated expression of P3H4, which is associated with pathological factors. The objective of this study was to elucidate the underlying mechanism of P3H4 in bladder cancer. Initially, we analyzed P3H4 gene expression using the TCGA database and evaluated P3H4 levels in clinical samples and various bladder cell lines. P3H4 was found to be markedly overexpressed in bladder cancer samples. Subsequently, bladder cancer cells were transfected with shRNA targeting P3H4 (sh-P3H4), sh-METTL3, and P3H4 overexpression vectors (P3H4 OE). Viability, migration, and invasion of bladder cancer cells were assessed using CCK-8, wound healing, and transwell assays. Western blot analysis was performed to determine the levels of EMT-associated proteins, while RNA stability assays determined the half-life of P3H4. Knockdown of P3H4 resulted in inhibition of bladder cancer cell proliferation, migration, invasion, and EMT progression. Mechanistically, METTL3 was found to regulate the mRNA stability of P3H4 in bladder cancer. Moreover, overexpression of P3H4 reversed the inhibitory effects of METTL3 knockdown on bladder cancer cell behaviors. Stable cell lines were established by infecting EJ cells with lentiviral vectors containing sh-METTL3 or P3H4 OE. These cells were then implanted into the skin of BALB/c nude mice, and IHC analysis was used to analyze the expression levels of EMT-associated proteins. In vivo studies demonstrated that inhibition of METTL3 suppressed bladder cancer growth and EMT through P3H4. In conclusion, our findings suggest that METTL3 regulates the proliferation, metastasis, and EMT progression of bladder cancer through P3H4, highlighting its potential as a therapeutic target.

Abstract
Background High-grade bladder cancer (HGBC) has a higher malignant potential, recurrence and progression rate compared to low-grade phenotype. Its early symptoms are often vague, making non-invasive diagnosis using urinary biomarkers a promising approach. Methods The gene expression data from urine samples of patients with HGBC was extracted from the GSE68020 dataset. The clinical information and gene expression data in tumor tissues of HGBC patients were obtained from The Cancer Genome Atlas (TCGA) database. Multivariate Cox analysis was used to predict the optimal risk model. The protein-protein interaction (PPI) analysis was performed via the Search Tool for the Retrieval of Interacting Genes (STRING) database and visualized using Cytoscape. Overall survival (OS) was evaluated in the Gene Expression Profiling Interactive Analysis (GEPIA) online platform. Competing endogenous RNA (ceRNA) network was also visualized using Cytoscape. The expression levels of specific genes were assessed through quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR). Moreover, co-expressed genes and potential biological functions related to specific genes were explored based on the Cancer Cell Line Encyclopedia (CCLE) database. Results A total of 560 differentially expressed genes (DEGs) were identified when comparing the urine sediment samples from HGBC patients with the benign ones. Using these urinary DEGs and the clinical information of HGBC patients, we developed an optimal risk model consisting of eight genes to predict the patient outcome. By integrating the node degree values in the PPI network with the expression changes in both urine and tissue samples, eighteen hub genes were selected out. Among them, DKC1 and SNRPG had the most prominent comprehensive values, and EFTUD2, LOR and EBNA1BP2 were relevant to a worse OS in bladder cancer patients. The ceRNA network of hub genes indicated that DKC1 may be directly regulated by miR-150 in HGBC. The upregulation of both SNRPG and DKC1 were detected in HGBC cells, which were also observed in various tumor tissues and malignant cell lines, displaying high correlations with other hub genes. Conclusions Our study may provide theoretical basis for the development of effective non-invasive detection and treatment strategies, and further research is necessary to explore the clinical applications of these findings.

Abstract
BACKGROUND Recurrent bladder cancer is the most common type of urinary tract malignancy; nevertheless, the mechanistic basis for its recurrence is uncertain. Innovative technologies such as single-cell transcriptomics and spatial transcriptomics (ST) offer new avenues for studying recurrent tumour progression at the single-cell level while preserving spatial data. METHOD This study integrated single-cell RNA (scRNA) sequencing and ST profiling to examine the tumour microenvironment (TME) of six bladder cancer tissues (three from primary tumours and three from recurrent tumours). FINDINGS scRNA data-based ST deconvolution analysis revealed a much higher tumour heterogeneity along with TME in recurrent tumours than in primary tumours. High-resolution ST analysis further identified that while the overall natural killer/T cell and malignant cell count or the ratio of total cells was similar or even lower in the recurrent tumours, a higher interaction between epithelial and immune cells was detected. Moreover, the analysis of spatial communication reveals a marked increase in activity between cancer-associated fibroblasts (CAFs) and malignant cells, as well as other immune cells in recurrent tumours. INTERPRETATION We observed an enhanced interplay between CAFs and malignant cells in bladder recurrent tumours. These findings were first observed at the spatial level.

Abstract
Objective: To improve the understanding of ectopic prostatic hyperplasia tissue with chronic inflammation, and to explore its occurrence mechanism and diagnosis and treatment. Methods: The clinical data of a patient with ectopic prostate tissue admitted to our hospital were analyzed and the literature was reviewed. Results: This paper reports a 71 year old male patient with benign hyperplasia in ectopic prostate tissue with chronic inflammation in bladder. This patient underwent a transperineal biopsy of prostate and transurethral resection of bladder mass because the imaging examination indicated a space-occupying mass and abnormally elevated blood prostate-specific antigen (PSA). During the operation, an isolated, smooth solid nodule was observed in the middle of the interureteric ridge in the bladder. Postoperative pathological examination of prostate biopsy specimen and bladder mass specimen showed benign hyperplasia in prostate tissue accompanied with local chronic inflammation. The patient received the postoperative follow-up for half a year, and no recurrence was observed. Conclusion: Intravesical ectopic prostatic hyperplasia tissue is clinically rare, and cases with chronic inflammation are even more rare. Diagnosis depends on imaging examination, and diagnosis is based on pathology. Surgical complete resection is currently the preferred treatment option.

Abstract
BACKGROUND Urinary bladder cancer (UBC) is a common malignancy of the urinary tract; however, the mechanism underlying its high recurrence and responses to immunotherapy remains unclear, making clinical outcome predictions difficult. Epigenetic alterations, especially DNA methylation, play important roles in bladder cancer development and are increasingly being investigated as biomarkers for diagnostic or prognostic predictions. However, little is known about hydroxymethylation since previous studies based on bisulfite-sequencing approaches could not differentiate between 5mC and 5hmC signals, resulting in entangled methylation results. METHODS Tissue samples of bladder cancer patients who underwent laparoscopic radical cystectomy (LRC), partial cystectomy (PC), or transurethral resection of bladder tumor (TURBT) were collected. We utilized a multi-omics approach to analyze both primary and recurrent bladder cancer samples. By integrating various techniques including RNA sequencing, oxidative reduced-representation bisulfite sequencing (oxRRBS), reduced-representation bisulfite sequencing (RRBS), and whole exome sequencing, a comprehensive analysis of the genome, transcriptome, methylome, and hydroxymethylome landscape of these cancers was possible. RESULTS By whole exome sequencing, we identified driver mutations involved in the development of UBC, including those in FGFR3, KDMTA, and KDMT2C. However, few of these driver mutations were associated with the down-regulation of programmed death-ligand 1 (PD-L1) or recurrence in UBC. By integrating RRBS and oxRRBS data, we identified fatty acid oxidation-related genes significantly enriched in 5hmC-associated transcription alterations in recurrent bladder cancers. We also observed a series of 5mC hypo differentially methylated regions (DMRs) in the gene body of NFATC1, which is highly involved in T-cell immune responses in bladder cancer samples with high expression of PD-L1. Since 5mC and 5hmC alternations are globally anti-correlated, RRBS-seq-based markers that combine the 5mC and 5hmC signals, attenuate cancer-related signals, and therefore, are not optimal as clinical biomarkers. CONCLUSIONS By multi-omics profiling of UBC samples, we showed that epigenetic alternations are more involved compared to genetic mutations in the PD-L1 regulation and recurrence of UBC. As proof of principle, we demonstrated that the combined measurement of 5mC and 5hmC levels by the bisulfite-based method compromises the prediction accuracy of epigenetic biomarkers.

Abstract
OBJECTIVE To investigate the difference in the levels of metabolites in the seminal plasma exosomes (SPE) of men with a high sperm DNA fragmentation index (DFI) from those with a low DFI. METHODS We performed a sperm exosomal metabolomics analysis of 5 healthy married men with DFI ≤15% (the control group) and another 5 with DFI ≥30% and matched in marital status, age and body mass index with the controls (the case group). Using high-performance liquid chromatography and mass spectrum, we examined the metabolites, observed their difference, and analyzed the metabolite enrichment pathway by Kyoto encyclopedia of genes and genomes (KEGG). According to the inclusion and exclusion criteria, we also selected 11 men in the control group and 20 men in the case group, and detected the differences in the seminal plasma amino acid and carnitine between the two groups using liquid measurement systems. RESULTS After primary and secondary analyses and qualified screening, 23 metabolites related to sperm DNA integrity were obtained, including 9 organic acids, 2 amino acid intermediate metabolites, and 11 acylcarnitine, purine, niacin and other intermediate products. KEGG enrichment analysis showed that 23 metabolites were mainly involved in the sphingoid signaling pathway, niacin and niacinamide metabolic pathway, and arginine and proline metabolic pathway. Further verification revealed no difference in the level of seminal plasma amino acid between the two groups, and significantly lower levels of seminal plasma acylcarnitine, free carnitine, propionylcarnitine, 3-hydroxybutyrylcarnitine and malonylcarnitine, 3-hydroxyisovalerylcarnitine and succinylcarnitine, and isoamyl (enylcarnitine) in the case group than in the controls (P<0.05). CONCLUSION There are significant differences in the levels of the metabolites organic acids, amino acids and acylcarnitine in the SPE of males with a high DFI from those with a low DFI. The level of seminal plasma acylcarnitine is significantly correlated with sperm DFI, which can be used as an indicator in quantitative and rapid assessment of the degree of sperm DNA damage.

Abstract
OBJECTIVE To study the effect and safety of microscopic varicocele cluster ligation (MVCL). METHODS We selected 28 patients undergoing bilateral microscopic spermatic vein ligation in Xuzhou Central Hospital from July 2021 to June 2022. Using the computerized randomization method, we performed MVCL or microscopic varicocele ligation (MVL) for the right or the left spermatic cord, respectively. We recorded the operation time, intraoperative blood loss, the numbers of the spermatic veins ligated and the arteries and lymphatic vessels preserved in each surgical side. A surgeon unaware of the surgical approach on the operative side collected the Visual Analogue Scale (VAS) pain scores, nodular foreign body sensation, relief of scrotal cramps, complications, and long-term recurrence from the patients. RESULTS Compared with the MVL group, the MVCL group showed significantly shorter time for spermatic vein ligation ([56.21±13.96] vs [31.43±10.13] min, P<0.01), lower VAS scores on the 1st postoperative day (P <0.05) and a lower incidence of intra-scrotal nodular foreign body sensation in the 1st postoperative month (P <0.05). There were no statistically significant differences in the intraoperative blood loss, numbers of spermatic veins ligated and arteries and lymphatic vessels preserved, VAS scores at 3 and 7 postoperative days, incidence of complications and long-term recurrence between the two groups (P >0.05). CONCLUSION MVCL is superior to MVL in reducing the time of spermatic vein ligation and improving the efficiency, efficacy and safety of the procedure, and therefore worthy of clinical promotion.

Abstract
Despite the success of targeted therapies in cancer treatment, therapy-induced resistance remains a major obstacle to a complete cure. Tumor cells evade treatments and relapse via phenotypic switching driven by intrinsic or induced cell plasticity. Several reversible mechanisms have been proposed to circumvent tumor cell plasticity, including epigenetic modifications, regulation of transcription factors, activation or suppression of key signaling pathways, as well as modification of the tumor environment. Epithelial-to-mesenchymal transition, tumor cell and cancer stem cell formation also serve as roads towards tumor cell plasticity. Corresponding treatment strategies have recently been developed that either target plasticity-related mechanisms or employ combination treatments. In this review, we delineate the formation of tumor cell plasticity and its manipulation of tumor evasion from targeted therapy. We discuss the non-genetic mechanisms of targeted drug-induced tumor cell plasticity in various types of tumors and provide insights into the contribution of tumor cell plasticity to acquired drug resistance. New therapeutic strategies such as inhibition or reversal of tumor cell plasticity are also presented. We also discuss the multitude of clinical trials that are ongoing worldwide with the intention of improving clinical outcomes. These advances provide a direction for developing novel therapeutic strategies and combination therapy regimens that target tumor cell plasticity.

Abstract
The current study aimed to investigate the sagittal morphology of the spinopelvic complex and the components of the lumbar spine in the normal population. In total, 132 adult volunteers were retrospectively evaluated and divided into four groups according to the Roussouly classification. Statistical analysis of radiological parameters, including lumbar lordosis (LL), thoracic kyphosis (TK), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), PI-LL, LL-TK, lumbar vertebral lordosis from L1 to L5 (L1L-L5L), the intervertebral angle from L1-L2 to L5-S1 (IVA1-2-IVA5-1), segmental lordosis from L1 to L5 (S1L-S5L), the proportion of L1-L5 (L1%-L5%), the proportion of the intervertebral angle from L1-L2 to L5-S1 (IVA1-2%-IVA5-1%), and proportion of segmental lordosis from L1 to L5 (S1L%-S5L%), was performed. Based on the classification, type II (n = 46) was the most common, followed by type I (n = 39), type III (n = 36), and type IV (n = 11). The quantitative values of the sagittal parameters of the four groups were obtained. Results showed a significant difference in terms of LL, PI, SS, and LL-TK. Further, L1%, L2%, L3%, IVA1-2%, IVA2-3%, S1L%, S2L%, and S3L% had an increasing trend. PI was positively correlated with LL, S1L, S2L, S3L, S4L, S1L%, and S2L%, but not with S5L%. In conclusion, pelvic parameters had a significant effect on lumbar curvature and lordosis distribution. Further, the abovementioned results were beneficial for individual surgical decision-making regarding targeted intervertebral angle, screw-insertion dimension, and rod contouring.

Abstract
OBJECTIVE To compare the safety of transurethral plasma resection of the prostate (TuPkRP) in the treatment of advanced PCa (APC)-related acute urinary retention (AUR) with that in the treatment of BPH-related AUR and investigate the oncologic characteristics of the PCa patient after TuPkRP. METHODS In this retrospective study, we first compared the baseline data between the patients with APC-related AUR (group A, n = 32) and those with BPH-related AUR (group B, n = 45) as well as their surgical parameters, such as the operation time, pre- and post-operative hemoglobin levels, IPSS at 3 months after TuPkRP and length of postoperative hospital stay. Then, we observed possible TuPkRP-induced tumor progression by comparing the oncologic parameters, such as the PSA level and ECT-manifested bone metastasis, between the APC-AUR patients treated by androgen-deprivation therapy (ADT) + TuPkRP and those treated by ADT only (group C, n = 24). RESULTS There were no statistically significant differences in the baseline data between the APC-AUR and BPH-AUR patients (P > 0.05). The operation time and postoperative hospital stay were significantly longer in the APC-AUR than in the BPH-AUR group (P < 0.05), but the decreases in the hemoglobin level and IPSS at 3 months after operation showed no significant differences between the two groups of patients (P > 0.05). Besides, no statistically significant differences were observed in the oncologic parameters between the APC-AUR patients treated by ADT + TuPkRP and those by ADT only (P > 0.05). CONCLUSION The safety of TuPkRP was not significantly lower and the rates of postoperative complications and adverse events were not significantly higher in the patients with APC-related AUR than in those with BPH-related AUR. And this surgical strategy did not significantly improve the progression of APC.

Abstract
On March 23, 2022, the U.S. Food and Drug Administration (FDA) approved Pluvicto (lutetium Lu 177 vipivotide tetraxetan), also known as 177Lu-PSMA-617, for the treatment of adult patients with metastatic castration-resistant prostate cancer (mCRPC) who have highly expressed prostate-specific membrane antigen (PSMA) and have at least one metastatic lesion. It is the first FDA-approved targeted radioligand therapy for eligible men with PSMA-positive mCRPC. Lutetium Lu 177 vipivotide tetraxetan is a radioligand that strongly binds to PSMA, making it ideal for treating cancers of the prostate by targeted radiation, resulting in DNA damage and cell death. PSMA is overexpressed in cancer cells while being lowly expressed in normal tissues, which makes it an ideal theranostic target. As precision medicine advances, this is a thrilling turning point for highly individualized treatments. This review aims to summarize the pharmacology and clinical studies of the novel drug lutetium Lu 177 vipivotide tetraxetan for the treatment of mCRPC, emphasizing its mechanism of action, pharmacokinetics and safety.

Abstract
The binding of programmed death-1 (PD-1) on the surface of T cells and PD-1 ligand 1 (PD-L1) on tumor cells can prevent the immune-killing effect of T cells on tumor cells and promote the immune escape of tumor cells. Therefore, immune checkpoint blockade targeting PD-1/PD-L1 is a reliable tumor therapy with remarkable efficacy. However, the main challenges of this therapy are low response rate and acquired resistance, so that the outcomes of this therapy are usually unsatisfactory. This review begins with the description of biological structure of the PD-1/PD-L1 immune checkpoint and its role in a variety of cells. Subsequently, the therapeutic effects of immune checkpoint blockers (PD-1 / PD-L1 inhibitors) in various tumors were introduced and analyzed, and the reasons affecting the function of PD-1/PD-L1 were systematically analyzed. Then, we focused on analyzing, sorting out and introducing the possible underlying mechanisms of primary and acquired resistance to PD-1/PD-L1 blockade including abnormal expression of PD-1/PD-L1 and some factors, immune-related pathways, tumor immune microenvironment, and T cell dysfunction and others. Finally, promising therapeutic strategies to sensitize the resistant patients with PD-1/PD-L1 blockade treatment were described. This review is aimed at providing guidance for the treatment of various tumors, and highlighting the drug resistance mechanisms to offer directions for future tumor treatment and improvement of patient prognosis.

Abstract
OBJECTIVE We aimed to assess the impact of the coronavirus disease 2019 (COVID-19) pandemic on the incidence of intussusception. MATERIALS AND METHODS Literature search of the PubMed and EMBASE databases was conducted for articles published in English until August 5, 2022. RESULTS Overall, 127 articles were retrieved, and five studies from South Korea (n=4) and the United States of America (n=1) containing clinical data from single-center medical records to nationwide databases were ultimately included in the systematic review. All the included studies reported that the incidence of intussusception decreased significantly during the pandemic period compared with the pre-pandemic period. The communicable disease incidence tended to decrease even as the incidence of non-communicable diseases did not significantly change. There was no significant difference in the time to diagnosis between the pre-pandemic and pandemic periods; however, the time to radiologic reduction was significantly longer or not depending on the study. CONCLUSIONS The COVID-19 pandemic significantly reduced the incidence of intussusception in children, supporting the hypothesis that infection plays a major role in the etiology of intussusception. Future studies in the late pandemic or post-pandemic era, which would represent the level of implementation of non-pharmaceutical interventions and social distancing as well as additional data from various countries will be needed.

Abstract
Background: With the continued advancement of RNA-seq (RNA-sequencing), microRNA (miRNA) editing events have been demonstrated to play an important role in different malignancies. However, there is yet no description of the miRNA editing events in recurrent bladder cancer.Objective: To identify and compare miRNA editing events in primary and recurrent bladder cancer, as well as to investigate the potential molecular mechanism and its impact on patient prognosis.Methods: We examined the mRNA and miRNA transcriptomes of 12 recurrent bladder cancer cases and 13 primary bladder cancer cases. The differentially expressed mRNA sequences were analyzed. Furthermore, we identified the differentially expressed genes (DEGs) in recurrent bladder cancer. The Gene Ontology (GO) functional enrichment analyses on DEGs and gene set enrichment analysis were performed. The consensus molecular subtype (CMS) classification of bladder cancer was identified using the Consensus MIBC package in R (4.1.0); miRNA sequences were then further subjected to differentially expressed analysis and pathway enrichment analysis. MiRNA editing events were identified using miRge3.0. miRDB and TargetScanHuman were used to predict the downstream targets of specific differentially edited or expressed miRNAs. The expression levels of miR-154-5p and ADAR were validated by RT-qPCR. Finally, survival and co-expression studies were performed on the TCGA-BLCA cohort.Results: First, the mRNA expression levels in recurrent bladder cancer changed significantly, supporting progression via related molecular signal pathways. Second, significantly altered miRNAs in recurrent bladder cancer were identified, with miR-154-5p showing the highest level of editing in recurrent bladder cancer and may up-regulate the expression levels of downstream targets HS3ST3A1, AQP9, MYLK, and RAB23. The survival analysis results of TCGA data revealed that highly expressed HS3ST3A1 and RAB23 exhibited poor prognosis. In addition, miR-154 editing events were found to be significant to CMS classification.Conclusion: MiRNA editing in recurrent bladder cancer was detected and linked with poor patient prognosis, providing a reference for further uncovering the intricate molecular mechanism in recurrent bladder cancer. Therefore, inhibiting A-to-I editing of miRNA may be a viable target for bladder cancer treatment, allowing current treatment choices to be expanded and individualized.

Abstract
Cancer is a major public health problem worldwide. Studies on oncogenes and tumor-targeted therapies have become an important part of cancer treatment development. In this review, we summarize and systematically introduce the gene enhancer of rudimentary homolog (ERH), which encodes a highly conserved small molecule protein. ERH mainly exists as a protein partner in human cells. It is involved in pyrimidine metabolism and protein complexes, acts as a transcriptional repressor, and participates in cell cycle regulation. Moreover, it is involved in DNA damage repair, mRNA splicing, the process of microRNA hairpins as well as erythroid differentiation. There are many related studies on the role of ERH in cancer cells; however, there are none on tumor-targeted therapeutic drugs or related therapies based on the expression of ERH. This study will provide possible directions for oncologists to further their research studies in this field.

Abstract
Background Melatonin is a hormone naturally produced by the pineal gland in the brain. In addition to modulating circadian rhythms, it has pleiotropic biological effects including antioxidant, immunomodulatory, and anti-cancer effects. Herein, we report that melatonin has the ability to decrease the growth and metastasis of androgen-dependent prostate cancer. Methods To evaluate the anti-cancer effect of melatonin on androgen-sensitive prostate cancer in vitro or in vivo, the effects of cell proliferation, apoptosis, migration and invasion were analyzed by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), colony formation, flow cytometry, Transwell assay, and immunohistochemistry (IHC), respectively. Next, the interaction between androgen receptor (AR) and SUMO specific protease 1 (SENP1) was detected by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blotting, and confirmed by luciferase reporter assay. Furthermore, the Small Ubiquitin-like Modifier (SUMO) proteins are a group of small proteins that are covalently attached to and detached from other proteins in cells to modify their function. (SUMOylation) of histone deacetylases 1 (HDAC1) was measured by proximity ligation assay (PLA). Results The treatment of melatonin cripples the transcriptional activity of AR, which is essential for the growth of the androgen-dependent prostate cancer cell, LNCaP. The lower activity of AR was dependent on melatonin induced SUMOylation of HDAC1, which has been established as a key factor for the transcriptional activity of AR. Mechanistically, the effect of melatonin on AR was due to the decreased SENP1 protein level and the subsequent increased HDAC1 SUMOylation level. The overexpression of SENP1 abrogated the anti-cancer ability of melatonin on LNCaP cells. Conclusions These findings indicate that melatonin is a suppressor of androgen-dependent prostate cancer tumorigenesis.

Abstract
Background Clear cell renal cell carcinoma (ccRCC) is one of the most lethal urological malignancies, but the pathogenesis and prognosis of ccRCC remain obscure, which need to be better understand. Methods Differentially expressed genes were identified and function enrichment analyses were performed using three publicly available ccRCC gene expression profiles downloaded from the Gene Expression Omnibus database. The protein-protein interaction and the competing endogenous RNA (ceRNA) networks were visualized by Cytoscape. Multivariate Cox analysis was used to predict an optimal risk mode, and the survival analysis was performed with the Kaplan-Meier curve and log-rank test. Protein expression data were downloaded from Clinical Proteomic Tumor Analysis Consortium database and Human Protein Atlas database, and the clinical information as well as the corresponding lncRNA and miRNA expression data were obtained via The Cancer Genome Atlas database. The co-expressed genes and potential function of candidate genes were explored using data exacted from the Cancer Cell Line Encyclopedia database. Results Of the 1044 differentially expressed genes shared across the three datasets, 461 were upregulated, and 583 were downregulated, which significantly enriched in multiple immunoregulatory-related biological process and tumor-associated pathways, such as HIF-1, PI3K-AKT, P53 and Rap1 signaling pathways. In the most significant module, 36 hub genes were identified and were predominantly enriched in inflammatory response and immune and biotic stimulus pathways. Survival analysis and validation of the hub genes at the mRNA and protein expression levels suggested that these genes, particularly complement component 3 (C3) and fibronectin 1 (FN1), were primarily responsible for ccRCC tumorigenesis and progression. Increased expression of C3 or FN1 was also associated with advanced clinical stage, high pathological grade, and poor survival in patients with ccRCC. Univariate and multivariate Cox regression analysis qualified the expression levels of the two genes as candidate biomarkers for predicting poor survival. FN1 was potentially regulated by miR-429, miR-216b and miR-217, and constructed a bridge to C3 and C3AR1 in the ceRNA network, indicating a critical position of FN1. Conclusions The biomarkers C3 and FN1 could provide theoretical support for the development of a novel prognostic tool to advance ccRCC diagnosis and targeted therapy.

Abstract
Objective To explore the significance of the prostate central gland to total gland volume ratio (PVc/PV) in the diagnosis of prostate cancer (PCa) in patients with prostate specific antigen (PSA) levels in the grey zone (4–10 ng/ml). Methods This retrospective study enrolled patients that had undergone prostate biopsy. The volume of the prostate and the central prostate gland were measured. The differences in PSA, the ratio of free to total PSA (f/tPSA), PSA density (PSAD) and PVc/PV between the PCa and non-PCa groups were compared. Receiver operating characteristic curve analysis for PCa and clinically significant PCa (csPCa) diagnosis were calculated according to PSA (reference), f/tPSA, PSAD and PVc/PV. Results This study enrolled 136 patients. There was no significant difference in PSA and f/tPSA between the PCa and non-PCa groups, while there were significant differences in PSAD and PVc/PV. The area under the curve values of PVc/PV for PCa or csPCa diagnosis were 0.876 and 0.933, respectively; and for PSAD, they were 0.705 and 0.790, respectively. These were significantly different compared with the PSA curve, whereas f/tPSA showed no significant difference from the PSA curve. Conclusion PVc/PV could be a predictor of PCa when PSA is between 4–10 ng/ml.

Abstract
Bladder urothelial carcinoma (BC) is a fatal invasive malignancy and the most common malignancy of the urinary system. In the current study, we investigated the function and mechanisms of Neuropilin-1 (NRP1), the co-receptor for vascular endothelial growth factor, in BC pathogenesis and progression. The expression of NRP1 was evaluated using data extracted from GEO and HPA databases and examined in BC cell lines. The effect on proliferation, apoptosis, angiogenesis, migration, and invasion of BC cells were validated after NRP1 knockdown. After identifying differentially expressed genes (DEGs) induced by NRP1 silencing, GO/KEGG and IPA® bioinformatics analyses were performed and specific predicted pathways and targets were confirmed in vitro. Additionally, the co-expressed genes and ceRNA network were predicted using data downloaded from CCLE and TCGA databases, respectively. High expression of NRP1 was observed in BC tissues and cells. NRP1 knockdown promoted apoptosis and suppressed proliferation, angiogenesis, migration, and invasion of BC cells. Additionally, after NRP1 silencing the activity of MAPK signaling and molecular mechanisms of cancer pathways were predicted by KEGG and IPA® pathway analysis and validated using western blot in BC cells. NRP1 knockdown also affected various biological functions, including antiviral response, immune response, cell cycle, proliferation and migration of cells, and neovascularisation. Furthermore, the main upstream molecule of the DEGs induced by NRP1 knockdown may be NUPR1, and NRP1 was also the downstream target of NUPR1 and essential for regulation of FOXP3 expression to activate neovascularisation. DCBLD2 was positively regulated by NRP1, and PPAR signaling was significantly associated with low NRP1 expression. We also found that NRP1 was a predicted target of miR-204, miR-143, miR-145, and miR-195 in BC development. Our data provide evidence for the biological function and molecular aetiology of NRP1 in BC and for the first time demonstrated an association between NRP1 and NUPR1, FOXP3, and DCBLD2. Specifically, downregulation of NRP1 contributes to BC progression, which is associated with activation of MAPK signaling and molecular mechanisms involved in cancer pathways. Therefore, NRP1 may serve as a target for new therapeutic strategies to treat BC and other cancers.

Abstract
BACKGROUND Solanum nigrum L. decoction has been used as a folklore medicine in China to prevent the postoperative recurrence of bladder cancer (BC). However, there are no previous pharmacological studies on the protective mechanisms of this activity of the plant. Thus, this study aimed to perform a systematic analysis and to predict the potential action mechanisms underlying S. nigrum activity in BC based on network pharmacology. METHODS Based on network pharmacology, the active ingredients of S. nigrum and the corresponding targets were identified using the Traditional Chinese Medicines for Systems Pharmacology Database and Analysis Platform database, and BC-related genes were screened using GeneCards and the Online Mendelian Inheritance in Man database. In addition, ingredient-target (I-T) and protein-protein interaction (PPI) networks were constructed using STRING and Cytoscape, Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted, and then the pathways directly related to BC were integrated manually to reveal the pharmacological mechanism underlying S. nigrum-medicated therapeutic effects in BC. RESULTS Seven active herbal ingredients from 39 components of S. nigrum were identified, which shared 77 common target genes related to BC. I-T network analysis revealed that quercetin was associated with all targets and that NCOA2 was targeted by four ingredients. Besides, interleukin 6 had the highest degree value in the PPI network, indicating a hub role. A subsequent gene enrichment analysis yielded 86 significant GO terms and 89 significant pathways, implying that S. nigrum had therapeutic benefits in BC through multi-pathway effects, including the HIF-1, TNF, P53, MAPK, PI3K/Akt, apoptosis and bladder cancer pathway. CONCLUSIONS S. nigrum may mediate pharmacological effects in BC through multi-target and various signaling pathways. Further validation is required experimentally. Network pharmacology approach provides a predicative novel strategy to reveal the holistic mechanism of action of herbs.

Abstract
Objective: To analyze the clinico pathological features, differential diagnosis and prognosis of metastatic renal cell carcinomas. Methods: The clinical data, histology, immunophenotype and follow-up data of 196 patients with metastatic renal cell carcinoma diagnosed from 1994 to 2017 at the Department of Pathology, Changhai Hospital, Naval Military Medical University, Shanghai, China were analyzed retrospectively. Results: There were 142 males and 54 females, with a median age of 61 years. The top three metastatic sites for the 196 cases of metastatic renal cell carcinoma were lung (31.1%, 61/196), bone (29.1%, 57/196) and digestive system (19.4%, 38/196). Among the pathological subtypes of metastasis, the proportion of clear cell renal cell carcinoma was 94.4% (185/196) and that of type II papillary renal cell carcinoma was 3.6% (7/196). The TFE3 translocated renal cell carcinoma and congestive tubular carcinoma were rare, with 3 cases and 1 case, respectively. CK, vimentin, CAⅨ and CD10 were expressed in all metastatic clear cell renal cell carcinomas. CK7, CD10 and P504s were expressed in papillary renal cell carcinomas. TFE3 was expressed in TFE3 translocated renal cell carcinoma. The collecting duct carcinoma was positive for HCK. Conclusions: Lung metastasis and bone metastasis are still the most frequent metastatic sites of renal cell carcinoma. Five years after primary lesion resection may be the high risk time for metastasis. Most of the metastases are solitary when they are first identified. To better diagnose and identify the renal origin of a metastatic renal cell carcinoma, one should consider morphological characteristics, clinical history information of the metastasis and the combined immunohistochemistry of CK, vimentin, CD10, CK7, TFE3, PAX2 and PAX8.

Abstract
BACKGROUND Ureteral intussusception, a rarely reported unique condition, occurs primarily as a complication of ureteric tumours. CASE PRESENTATION We present a case of ureteral intussusception accompanied with a large ureteral polyp periodically protruding into the bladder cavity occurring in a 56-year-old man who experienced vague flank pain and intermittent haematuria. The patient was successfully treated by ureteroscopic cauterization combined with partial ureterectomy with reanastomosis. CONCLUSIONS This is the first report that describes polyp-related ureteral intussusception using comprehensive and representative ureteroscopic images and video. Our findings suggest that ureteroscopy is vital for diagnosis. Extensive biopsies through ureteroscopy are less invasive, and make it easier to exclude the presence of ureteral malignancies. Ureteroscopic resection of the whole polyp with its stalk and intussusceptum using Holmium: YAG laser did not seem viable in this case. However, cauterization of partial polyp tissues followed by open surgery for segmental resection of the ureter with reanastomosis is helpful in controlling such patient well-being.

Abstract
BACKGROUND: Long-term mortality following tuberculosis (TB) diagnosis in Korea remains unclear.METHODS: The present study used data from the National Health Insurance Service database, an extensive health-related database including most Korean residents. TB patients were identified using International Classification of Diseases, Tenth Revision coding (A15-19, U88.0-88.1) and the type of anti-TB drug(s) between 2003 and 2016. Long-term mortality and causes of death in TB patients were analysed.RESULTS: A total of 357 211 individuals had TB over the period from 2003 to 2016 and 103 682 died. The mean age of the cohort was 54.7 ± 20.7 years, and 59.8% were male. The survival probability of TB patients at 1, 5, and 10 years after diagnosis was 87.8%, 75.3%, and 63.3%, respectively. High mortality and TB-related death rates were especially prominent in the early stages after TB diagnosis. The overall standardized mortality ratio of TB patients to the general Korean population was 3.23 (95% confidence interval 3.21-3.25).CONCLUSION: Mortality in TB patients was especially high in the early stages of disease after TB diagnosis, and mostly due to TB. This figure was approximately three-times higher than the mortality rate in the general population.

Abstract
OBJECTIVE To investigate the clinical effect of plaque excision plus autologous perididymal patch grafting in the treatment of Peyronie's disease. METHODS This study included 10 patients with Peyronie's disease received in our Department of Urology between January 2013 and December 2015, who had failed to respond to over 12 months of expectant drug therapy and remained stable for more than 6 months, none able to perform sexual intercourse due to penile curvature (>60°). All the patients underwent plaque excision plus autologous perididymal patch grafting. RESULTS Postoperative follow-up ranged from 6 to 24 months. All the patients achieved normal penile erection, without testicular atrophy, torsion or necrosis at the surgery side and all were satisfied with the surgical results without complaining about obvious penile shortening. CONCLUSIONS Plaque excision plus autologous perididymal patch grafting is a safe, simple, economic and effective method for the treatment of Peyronie's disease.

Abstract
Bladder cancer is one of the most common cancers. Approaches that block tumor angiogenesis are a new therapeutic strategy for locally advanced or metastatic BC. VEGF/VEGFR signaling has been obviously and negatively correlated with the progression and invasion of cancer. In this study, we constructed the recombinant adenovirus vAd-VEGFR-3 to investigate its antitumor effector in vitro/vivo. First, we used the recombinant adenovirus vAd-VEGFR-3 to infect bladder cancer cells and then collected the cell culture supernatant to treat human umbilical vein endothelial cells (HUVECs). The proliferation, migration and apoptosis of HUVECs were respectively detected by MTT, transwell and Annexin V-FITC/PI double staining. In addition, mouse bladder mucosa was injured by trypsin, and the orthotopic transplantation model of human bladder cancer was successfully constructed to clarify the anti-tumor effect of Ad-VEGFR in vivo. The results showed that Ad-VEGFR could inhibit the cancer's proliferation and migration, while promoting the apoptosis of HUVECs in vitro. Moreover, Ad-VEGFR could significantly promote the apoptosis of bladder cancer cells and then prevent tumor growth in vivo. In addition, it also down-regulated the expression levels of CD31, an endothelial cell marker which is closely related to the angiogenesis. Taken together, it suggests that the infection of adenovirus-carrying VEGFR in bladder cancer cells may inhibit blood vessel formation and prevent tumor progression.

Abstract
OBJECTIVE To gain a deeper insight into the local anatomic structures of the seminal vesicle and ejaculatory duct and provide some anatomic guidance in seminal vesiculoscopy. METHODS We analyzed the clinical data on 48 cases of seminal vesiculoscopy and recorded the surgical approaches to the seminal vesicle and clinical effects after operation. At the same time, we made an anatomic study of the seminal vesicle, ejaculatory duct and prostatic utricle and simulated the surgical approaches in 12 adult pelvis specimens. RESULTS The anatomical results accorded well with the surgical findings. The ejaculatory ducts failed to be revealed for 52.1%(25/48), but 93.8%(45/48) of the operations were completed through different approaches into the seminal vesicle. CONCLUSIONS Transurethral seminal vesiculoscopy can be applied in the treatment of seminal tract and seminal vesicle diseases, but has its obvious limitations and has to be used with other strategies to achieve better results.

Abstract
The present study explored the effects of disodium cantharidinate (DC) on the peripheral blood-derived dendritic cells of patients with bladder carcinoma. The peripheral blood mononuclear cells from the 15 cases of urinary bladder carcinoma of middle and advanced stage were separated, and dendritic cells were prepared. The morphological changes of dendritic cells were observed. Flow cytometry was used to detect the expression levels of CD1a and CD83 on dendritic cell surface. MTT assay was utilized to measure the proliferation ability of allogeneic lymphocyte stimulated by DC. Annexin V-FITC/propidium iodide (PI) double staining flow cytometry method was carried out to detect cell apoptosis after treatment with DC. The changes in caspase-3 and PARP expression levels were investigated by western blot method. The high-dose DC resulted in a significant increase in the expressions of dendritic cell phenotyptic molecules CDla and CD83 as compared to control group. In addition, the proliferation index of allogenic lymphocyte stimulated by DC was significantly higher than that of control group. Moreover, MTT assay showed significant inhibition of the growth of BIU-87 cells. After 24 h of DC treatment, double staining flow cytometry confirmed the ability of DC to induce cell apoptosis. Further, western blot method showed a significant elevation of caspase-3 and PARP protein expression after DC treatment. In conclusion, DC treatment could induce dendritic cell maturation of patient with carcinoma of urinary bladder and promote its functional changes. Furthermore, DC was able to inhibit the proliferation of cell BIU-87 and also has the ability to induce cell apoptosis.

Abstract
Necroptosis has been found to be involved in the pathogenesis of some lung diseases, but its role in hyperoxic acute lung injury (HALI) is still unclear. This study aimed to investigate contribution of necroptosis to the pathogenesis of HALI induced by hyperbaric hyperoxia exposure in a rat model. Rats were divided into control group, HALI group, Nec-1 (necroptosis inhibitor) group and edaravone group. Rats were exposed to pure oxygen at 250 kPa for 6 h to induce HALI. At 30 min before hyperoxia exposure, rats were intraperitoneally injected with Nec-1 or edaravone, and sacrificed at 24 h after hyperoxia exposure. Lung injury was evaluated by histology, lung water to dry ratio (W/D) and bronchoalveolar lavage fluid (BALF) biochemistry; the serum and plasma oxidative stress, expression of RIP1, RIP3 and MLKL, and interaction between RIP1 and RIP3 were determined. Results showed hyperoxia exposure significantly caused damage to lung and increased necroptotic cells and the expression of RIP1, RIP3 and MLKL. Edaravone pre-treatment not only inhibited the oxidative stress in HALI, but also reduced necroptotic cells, decreased the expression of RIP1, RIP3 and MLKL and improved lung pathology. Nec-1 pretreatment inhibited necroptosis and improved lung pathology, but had little influence on oxidative stress. This study suggests hyperoxia exposure induces oxidative stress may activate necroptosis, involving in the pathology of HALI, and strategies targeting necroptosis may become promising treatments for HALI.

Abstract
The effect of recombinant and purified tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) on the proliferation and apoptosis of PC-3 prostate cancer cells and the 5637 bladder cancer cells were investigated. We used a cell proliferation assay and flow cytometry to measure the proliferation and apoptosis of cancer cells after 24-h incubation of PC-3 and 5637 cells with different concentrations of TRAIL. PC-3 cell proliferation rate significantly decreased when TRAIL was used at concentrations of 20, 40, 80 and 160 ng/ml compared with the untreated group. In the 5637 cells, the proliferation rate significantly decreased when TRAIL was used at concentrations of 5, 10, 20 and 40 ng/ml compared with the untreated group. The flow cytometry results also confirmed that the apoptosis rate of both cancer cell lines increased with TRAIL protein concentration. In conclusion, recombinant and purified TRAIL has anticancer activity by inhibiting proliferation and promoting apoptosis of prostate and bladder cancer cells.

Abstract
OBJECTIVE To investigate the effects of cynomorium songaricum (CS) decoction on the testis weight, serum testosterone level, and sperm parameters of rats with oligoasthenospermia (OAS), explore its action mechanism of improving the proliferation of undifferentiated spermatogonial cells, and provide some experimental and theoretical evidence for the development of new Chinese drugs for OAS. METHODS Thirty 8-week-old male SD rats were randomly divided into five groups of equal number: blank control, model control, high-dose CS, medium-dose CS, and low-dose CS. OAS models were established by intraperitoneal injection of cyclophosphamide and, a month later, treated intragastrically with normal saline or CS at 2, 1, and 0.5 g per kg of the body weight per day, all for 4 weeks. Then, the testes of the animals were harvested to obtain the testicular weight, sperm concentration and motility, and the level of serum testosterone (T), detect the expressions of the transcription factor 1 (Oct4), Thy-1 cell surface antigen (Thy1), promyelocytic leukemia zinc finger (PLZF), KIT proto-oncogene receptor tyrosine kinase (C-kit) and glial cell-derived neurotrophic factor (GDNF) in the testis tissue of the rats in the low-dose CS group by real-time PCR. RESULTS The testis weights in the blank control, model control, high-dose CS, medium-dose CS, and low-dose CS groups were (1.52±0.06), (1.55±0.06), (1.43±0.30), (1.35±0.40) and (1.34±0.04) g, respectively, not significantly different in the blank and model controls from those in the CS groups (P>0.05). The visual field sperm count per 10 HP was significantly increased in the high-, medium-, and low-dose CS groups (202±20, 196±5 and 216±25) as compared with the blank and model controls (200±15 and 134±30) (P<0.05). The mRNA expressions of the Oct4, Thy1, PLZF and GDNF genes were remarkably higher in the low-dose CS group than in the controls (P<0.05), but that of the C-kit gene showed no significant difference from the latter (P>0.05). The visual field sperm motility per 10 HP was markedly increased in the blank control ([52.1±5.5]%), model control ([38.1±2.5]%), high-dose CS ([59.1±9.5]%), medium-dose CS ([58.7±9.5]%), and low-dose CS ([49.6±1.0]%) groups, and so was the level of serum testosterone ([190±87.5], [82.5±25.8], [229±75.6], [331±86.7] and [185±82.4] mmol/L), both remarkably higher in the CS groups than in the model controls (P<0.05) but with no statistically significant difference between the CS groups and the blank controls (P>0.05). CONCLUSIONS CS can significantly improve sperm concentration, sperm motility and serum T level in OAS rats, probably by inducing the expression of GDNF in the rat Sertoli cells, promoting the proliferation of undifferentiated spermatogonial cells, and enhancing spermatogenesis.

Abstract
In the present study, the clinical effects of flexible ureteroscopy lithotripsy (FURL) and percutaneous nephrolithotomy (PCNL) for the treatment of kidney stones of ≤2 cm was studied. Seventy-two patients with kidney stones were randomly divided into the FURL group (n=39) under ureteroscope lithotripsy with holmium laser and PCNL group (n=33) under PCNL with holmium laser and compared their clinical effects. At 3 months after the operation, the stone removal rate of the FURL group was significantly higher than that of the PCNL group. The subgroup analysis revealed that the difference in the lower kidney calyx was more obvious (P<0.05) while the difference in the complex kidney stones was not statistically significant (P>0.05). The incidence of complications of the FURL group was significantly lower than that of the PCNL group (P<0.05). The operation time and recurrence rate of the FURL group were significantly less than that of the PCNL group (P<0.05). Differences regarding the creatinine and urea nitrogen levels before operation, and 3 and 7 days after the operation between the two groups were not statistically significant (P>0.05). Additionally, 3 and 7 days after operation, the cystatin C levels of the FURL group were significantly higher than those of the PCNL group, and the KIM-1 levels were significantly lower than the PCNL group (P<0.05). In conclusion, compared with PCNL with holmium laser, FURL with holmium laser was more safe and effective in treating kidney stones ≤2 cm. Therefore, the method is worthy of wide application in clinic.

Abstract
We aim to investigate the correlations between hemodynamic parameters, penile rigidity grading, and the therapeutic effects of phosphodiesterase type 5 inhibitors using color Doppler flow imaging after intracavernosal injection in patients with erectile dysfunction. This study involved 164 patients. After intracavernosal injection with a mixture of papaverine (60 mg), prostaglandin E 1 (10 mg), and lidocaine (2%, 0.5-1 ml), the penile vessels were assessed using color Doppler flow imaging. Penile rigidity was classified based on the Erection Hardness Score system as Grades 4, 3, 2 or 1 (corresponding to Schramek Grades V to II). Then, the patients were given oral sildenafil (50-100 mg) and scored according to the International Index of Erectile Function (IIEF-5) questionnaire. The number of patients with penile rigidities of Schramek Grades II to V was 14, 18, 21, and 111, respectively. The IIEF-5 score was positively correlated with the refilling index of the penile cavernosal artery (r = 0.79, P< 0.05), the peak systolic velocity (r = 0.45, P< 0.05), and penile rigidity (r = 0.75, P< 0.05), and was negatively correlated with the end diastolic velocity (r = -0.74, P< 0.05). For patients with erectile dysfunction, both the IIEF-5 score after sildenafil administration, which is correlated with penile rigidity, and the hemodynamic parameters detected using color Doppler flow imaging may predict the effects of phosphodiesterase type 5 inhibitor treatment and could provide a reasonable model for the targeted-treatment of erectile dysfunction.

Abstract
Oxygen is essential to sustain life, but at a high partial pressure oxygen may cause toxicity to the human body. These injuries to the lung are known as hyperoxic acute lung injury [HALI]). To date, numerous studies have been conducted to investigate the pathogenesis of HALI, for which some hypotheses have been proposed. Accumulating evidence indicates that the renin-angiotensin system (RAS) plays an important role in the pathogenesis of some lung diseases, including acute lung injury (ALI), chronic obstructive pulmonary disease (COPD) and HALI. In this review, we briefly introduce the classic RAS, local (tissue) RAS and intracellular RAS, and we summarize findings on the relationship between local/classic RAS and HALI. The importance--and ambiguity--of the results of these studies indicate a need for further investigations of the RAS and its role in the patho- genesis of HALI.

Abstract
Hyperoxia induced lung injury (HILI) refers to the acute lung injury secondary to prolonged exposure to hyperoxia at elevated partial pressure. With the advent of efficient systems for delivery of high concentrations of oxygen in hospitals, the population at risk for this condition has been markedly increased. Although numerous studies have been conducted to investigate the pathogenesis of HILI, the specific mechanism is still poorly understood and some hypotheses have been proposed. Transforming growth factor β (TGF-β) is a secreted protein that controls proliferation, cellular differentiation and other functions in most cells and is a type of cytokine that plays a role in many diseases. In this mini-review, we summarize the role of TGF-β in HILI according to its relationships with reactive oxygen species (ROS), pro-inflammatory cytokines, cell apoptosis and pulmonary fibrosis. We hope it may help the understanding of pathogenesis of HILI and provide a greater understanding for the target therapy of HILI.

Abstract
The aim of the study was to optimize the in vitro induction and expression of the human tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and also study the processes of its denaturation, renaturation, and purification. The pGEX-6P-1/TRAIL114-281 plasmid was induced by isopropyl-β-D-1-thiogalactopyranoside (IPTG) in Escherichia coli BL21 (DE3), and the expressed target protein was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The protein expressed in the form of inclusion body was first denaturalized and then renaturalized by dilution and dialysis technique. GST-rTRAIL114-281 fusion protein was purified by Glutathione-Superflow Resin affinity chromatography and confirmed by Western blot. The molecular weight of GST-rTRAIL expressed in E. coli BL21 (DE3) was approximately 40 kDa. GST-rTRAIL was mainly expressed in the form of inclusion bodies. An optimum expression was induced by IPTG at a concentration of 0.2 mM for 8 h at 37 °C. Glutathione-Superflow Resin affinity chromatography yielded the purified GST-rTRAIL protein which was confirmed by Western blot using anti-GST mouse monoclonal antibody. The optimum prokaryotic cell expression of the human GST-rTRAIL was obtained by 0.2 mM IPTG induction for 8 h at 37 °C. The denatured inclusion body protein can be refolded by dilution and dialysis and purified by Glutathione-Superflow Resin affinity chromatography.

Abstract
Neuropilin-1 (NRP-1) overexpression has been reported in a variety of human cancers. However, the role of NRP-1 in bladder cancer (BC) remains unclear. The aim of present study was to analyze NRP-1 protein expression in BC tissues and to assess its prognostic significance for BC. NRP-1 messenger ribonucleic acid (mRNA) and protein expression were determined by real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) and immunohistochemistry in specimens of primary cancer and their adjacent noncancerous tissues in BC patients. Additionally, NRP-1 protein expression in 139 archived paraffin-embedded BC samples was analyzed by immunohistochemistry and correlated with clinicopathological characteristics and survival. Student's t test, Spearman's rank correlation, Kaplan-Meier plots, and Cox's proportional hazards regression model were used to analyze the data. By qRT-PCR and immunohistochemistry, the levels of NRP-1 mRNA and protein were significantly higher in BC, compared to that in adjacent noncancerous tissues (P<0.001). High expression of NRP-1 was significantly associated with histologic grade (P=0.016) and tumor stage (P=0.001). Multivariate analysis showed that high expression of NRP-1 was an independent prognostic factor for overall survival. Our study suggests that overexpression of NRP-1 may play an important role in the progression of BC, and NRP-1 expression may serve as a biomarker for poor prognosis for BC.

Abstract
OBJECTIVE To evaluate the effect of elective microscopic resection of dorsal penile nerves in the treatment of primary premature ejaculation (PPE). METHODS Seventy-eight PPE patients received elective microscopic resection of dorsal penile nerves, 5 branches in 9 cases, 6 in 17, 7 in 15, 8 in 14, 9 in 8, 10 in 6, 11 in 6, and 12 in 3. The patients were followed up for 12 months, and their intravaginal ejaculation latency time (IELT) and sexual intercourse satisfaction scores were recorded before and after treatment. RESULTS Compared with the baseline, the IELT was significantly prolonged after surgery ([0.86 +/- 0.32] vs [6.65 +/- 3.9] min, P < 0.01), and the sexual intercourse satisfaction scores of the patients were dramatically increased (7.32 +/- 2.52 vs 12.32 +/- 3.76, P < 0.01), so were those of their sexual partners (4.46 +/- 1.36 vs 12.73 +/- 1.45, P < 0.01). CONCLUSION Elective microscopic resection of dorsal penile nerves is safe and effective for the treatment of PPE.

Abstract
BACKGROUND AND OBJECTIVE Polycan is a promising candidate for the treatment of periodontal disease. This study was undertaken to examine whether Polycan, a type of β-glucan, has a protective effect on ligature-induced experimental periodontitis and related alveolar bone loss in Sprague-Dawley rats. MATERIAL AND METHODS Polycan was orally administered, daily, for 10 d, at 21.25, 42.5 or 85 mg/kg, beginning 1 d after ligation. Changes in body weight and alveolar bone loss were monitored, and the anti-inflammatory effects of Polycan were determined by measuring the levels of myeloperoxidase (MPO), interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α) in gingival tissue. We also evaluated inducible nitric oxide synthase (iNOS) activity and malondialdehyde (MDA) concentrations as a measure of the antioxidant effect. RESULTS Ligature placement led to a marked decrease in body weight, increased alveolar bone loss and increased concentrations of MPO, IL-1β, TNF-α and MDA, as well as increased iNOS activity and inflammatory cell infiltration and decreased collagen-fiber content. Histological examination revealed increases in the number and activity of osteoclast cells, decreases in alveolar bone volume and elevated percentages of osteclasts on the alveolar bone surface. Daily oral treatment with 42.5 or 85 mg/kg of Polycan for 10 d led to significant, dose-dependent inhibition of the effect of ligature placement. CONCLUSION Taken together, these results suggest that 10 d of oral treatment with Polycan effectively inhibits ligature placement-induced periodontitis and related alveolar bone loss via an antioxidant effect.

Abstract
A simple and efficient solid-phase extraction – spectrofluorimetric method has been developed to determine glutathione (GSH). Fluorescent probe N-(4,4-difluoro-5,7-dimethyl-4-bora-3a,4a-diaza-s-indacene-3-yl)methyl)iodoacetamide (BODIPY Fl-C1-IA) was used as the derivatization reagent. The procedure was based on a BODIPY Fl-C1-IA selective reaction with GSH to form the highly fluorescent product BODIPY Fl-C1-IA–GSH, using a solid-phase extraction column and spectrofluorimetric determination. The variables affecting analytical performance were studied and optimized. The calibration graph using the preconcentration system for GSH was linear over the range of 1–200 nmol/L with a limit of detection of 0.05 nmol/L (signal-to-noise ratio = 3). The relative standard deviation for six replicate determinations of GSH at the 100 nmol/L concentration level was 3.9%. The method was applied to water samples and average recoveries between 87.5% and 111.5% were obtained for spiked samples.

Abstract
Reversible posterior leucoencephalopathy syndrome is a neurological condition seen in various areas of acute medicine, including the administration of antineoplastic therapies used in haemato-oncology patients. It is a rare complication that has been increasingly recognized. It is characterized by altered mental status, visual disturbance, headache and seizures. Magnetic resonance imaging typically shows vasogenic oedema in the posterior regions of the brain. Although its name suggests reversibility, it may result in an irreversible brain injury without prompt treatment. Therefore, it is vital for treating clinicians to recognize this syndrome. We describe the case of a 55-year-old woman with advanced pancreatic adenocarcinoma, who developed clinical and radiological manifestations consistent with this syndrome as a complication of gemcitabine monotherapy.

Abstract
A nano-material carboxylic acid functionalized graphene (graphene-COOH) was prepared and used to construct a novel biosensor for the simultaneous detection of adenine and guanine. The direct electrooxidation behaviors of adenine and guanine on the graphene-COOH modified glassy carbon electrode (graphene-COOH/GCE) were carefully investigated by cyclic voltammetry and differential pulse voltammetry. The results indicated that both adenine and guanine showed the increase of the oxidation peak currents with the negative shift of the oxidation peak potentials in contrast to that on the bare glassy carbon electrode. The electrochemical parameters of adenine and guanine on the graphene-COOH/GCE were calculated and a simple and reliable electroanalytical method was developed for the detection of adenine and guanine, respectively. The modified electrode exhibited good behaviors in the simultaneous detection of adenine and guanine with the peak separation as 0.334V. The detection limit for individual determination of guanine and adenine was 5.0×10(-8)M and 2.5×10(-8)M (S/N=3), respectively. Furthermore, the measurements of thermally denatured single-stranded DNA were carried out and the value of (G+C)/(A+T) of single-stranded DNA was calculated as 0.80. The biosensor exhibited some advantages, such as simplicity, rapidity, high sensitivity, good reproducibility and long-term stability.

Abstract
Ptercarpus santalinus (Fabaceae) has been used as a folk remedy in Korea, and it has been shown to exhibit antiinflammations, antiulcers and anticancer effects. In this study, therefore, we report the cytotoxic activity and the mechanism of cell death exhibited by the methanol extract of Ptercarpus santalinus (MEPS) against human cervical adenocarcinoma cell line, HeLa. Treatment of HeLa cells with various concentrations of MEPS resulted in growth inhibition and induction of apoptosis in a dose-dependent manner as determined by cell viability, chromatin condensation, DNA fragmentation and sub-G1 phase accumulation. In Western blot analysis, apoptosis in the HeLa cells was associated with the release of cytochrome C from mitochondria into the cytosol, activation of caspases-3, -8, -9 and proteolytic cleavage of PARP. These results suggest that MEPS exhibits antiproliferative effect on HeLa cells via apoptosis, and it may be a potential candidate in field of anticancer drug discovery.
