Abstract
Background Acquiring well-focused digital images of cytology slides with scanners can be challenging due to the 3-dimensional nature of the slides. This study evaluates performances of whole-slide images (WSIs) obtained from 2 different cytopreparations by 2 distinct scanners with 3 focus modes. Methods Fourteen urine specimens were collected from patients with urothelial carcinoma. Each specimen was equally divided into 2 portions, prepared with Cytospin and ThinPrep methods and scanned for WSIs using Leica (Aperio AT2) and Hamamatsu (NanoZoomer S360) scanners, respectively. The scan settings included 3 focus modes (default, semi-auto, and manual) for single-layer scanning, along with a manual focus mode for 21 Z-layers scanning. Performance metrics were evaluated including scanning success rate, artificial intelligence (AI) algorithm-inferred atypical cell numbers and coverage rate (atypical cell numbers in single or multiple Z-layers divided by the total atypical cell numbers in 21 Z-layers), scanning time, and image file size. Results The default mode had scanning success rates of 85.7% or 92.9%, depending on the scanner used. The semi-auto mode increased success to 92.9% or 100%, and manual even further to 100%. However, these changes did not affect the standardized median atypical cell numbers and coverage rates. The selection of scanners, cytopreparations, and Z-stacking influenced standardized median atypical cell numbers and coverage rates, scanning times, and image file sizes. Discussion Both scanners showed satisfactory scanning. We recommend using semi-auto or manual focus modes to achieve a scanning success rate of up to 100%. Additionally, a minimum of 9-layer Z-stacking at 1 μm intervals is required to cover 80% of atypical cells. These advanced focus methods do not impact the number of atypical cells or their coverage rate. While Z-stacking enhances the AI algorithm's inferred quantity and coverage rates of atypical cells, it simultaneously results in longer scanning times and larger image file sizes.

Evaluating Urine Cytology Slide Digitization Efficiency: A Comparative Study Using an Artificial Intelligence-Based Heuristic Scanning Simulation and Multiple-Z-Plane Scanning.

Abstract
INTRODUCTION Digitizing cytology slides presents challenges because of their three-dimensional features and uneven cell distribution. While multi-Z-plane scan is a prevalent solution, its adoption in clinical digital cytopathology is hindered by prolonged scanning times, increased image file sizes, and the requirement for cytopathologists to review multiple Z-plane images. METHODS This study presents heuristic scan as a novel solution, using an artificial intelligence (AI)-based approach specifically designed for cytology slide scanning as an alternative to the multi-Z-plane scan. Both the 21 Z-plane scan and the heuristic scan simulation methods were used on 52 urine cytology slides from three distinct cytopreparations (Cytospin, ThinPrep, and BD CytoRich™ (SurePath)), generating whole-slide images (WSIs) via the Leica Aperio AT2 digital scanner. The AI algorithm inferred the WSI from 21 Z-planes to quantitate the total number of suspicious for high-grade urothelial carcinoma or more severe cells (SHGUC+) cells. The heuristic scan simulation calculated the total numbers of SHGUC+ cells from the 21 Z-plane scan data. Performance metrics including SHGUC+ cell coverage rates (calculated by dividing the number of SHGUC+ cells identified in multiple Z-planes or heuristic scan simulation by the total SHGUC+ cells in the 21 Z-planes for each WSI), scanning time, and file size were analyzed to compare the performance of each scanning method. The heuristic scan's metrics were linearly estimated from the 21 Z-plane scan data. Additionally, AI-aided interpretations of WSIs with scant SHGUC+ cells followed The Paris System guidelines and were compared with original diagnoses. RESULTS The heuristic scan achieved median SHGUC+ cell coverage rates similar to 5 Z-plane scans across three cytopreparations (0.78-0.91 vs. 0.75-0.88, P=0.451-0.578). Notably, it substantially reduced both scanning time (137.2-635.0 seconds vs. 332.6-1278.8 seconds, P<0.05) and image file size (0.51-2.10 GB vs. 1.16-3.10 GB, P<0.05). Importantly, the heuristic scan yielded higher rates of accurate AI-aided interpretations compared to the single Z-plane scan (62.5% vs. 37.5%). CONCLUSION We demonstrated that the heuristic scan offers a cost-effective alternative to the conventional multi-Z-plane scan in digital cytopathology. It achieves comparable SHGUC+ cell capture rates while reducing both scanning time and image file size, promising to aid digital urine cytology interpretations with a higher accuracy rate compared to the conventional single (optimal) plane scan. Further studies are needed to assess the integration of this new technology into compatible digital scanners for practical cytology slide scanning.

Abstract
Liver fibrosis is a chronic liver disease caused by prolonged liver injuries. Excessive accumulation of extracellular matrix replaces the damaged hepatocytes, leading to fibrous scar formation and fibrosis induction. Lactoferrin (LF) is a glycoprotein with a conserved, monomeric signal polypeptide chain, exhibiting diverse physiological functions, including antioxidant, anti-inflammatory, antibacterial, antifungal, antiviral, and antitumoral activities. Previous study has shown LF's protective role against chemically-induced liver fibrosis in rats. However, the mechanisms of LF in liver fibrosis are still unclear. In this study, we investigated LF's mechanisms in thioacetamide (TAA)-induced liver fibrosis in rats and TGF-β1-treated HSC-T6 cells. Using ultrasonic imaging, H&E, Masson's, and Sirius Red staining, we demonstrated LF's ability to improve liver tissue damage and fibrosis induced by TAA. LF reduced the levels of ALT, AST, and hydroxyproline in TAA-treated liver tissues, while increasing catalase levels. Additionally, LF treatment decreased mRNA expression of inflammatory factors such as Il-1β and Icam-1, as well as fibrogenic factors including α-Sma, Collagen I, and Ctgf in TAA-treated liver tissues. Furthermore, LF reduced TAA-induced ROS production and cell death in FL83B cells, and decreased α-SMA, Collagen I, and p-Smad2/3 productions in TGF-β1-treated HSC-T6 cells. Our study highlights LF's ability to ameliorate TAA-induced hepatocyte damage, oxidative stress, and liver fibrosis in rats, potentially through its inhibitory effect on HSC activation. These findings suggest LF's potential as a therapeutic agent for protecting against liver injuries and fibrosis.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a progressive and life-threatening lung disease with high mortality rates. The limited availability of effective drugs for IPF treatment, coupled with concerns regarding adverse effects and restricted responsiveness, underscores the need for alternative approaches. Kefir peptides (KPs) have demonstrated antioxidative, anti-inflammatory, and antifibrotic properties, along with the capability to modulate gut microbiota. This study aims to investigate the impact of KPs on bleomycin-induced pulmonary fibrosis. METHODS Mice were treated with KPs for four days, followed by intratracheal injection of bleomycin for 21 days. Comprehensive assessments included pulmonary functional tests, micro-computed tomography (µ-CT), in vivo image analysis using MMPsense750, evaluation of inflammation- and fibrosis-related gene expression in lung tissue, and histopathological examinations. Furthermore, a detailed investigation of the gut microbiota community was performed using full-length 16 S rRNA sequencing in control mice, bleomycin-induced fibrotic mice, and KPs-pretreated fibrotic mice. RESULTS In KPs-pretreated bleomycin-induced lung fibrotic mice, notable outcomes included the absence of significant bodyweight loss, enhanced pulmonary functions, restored lung tissue architecture, and diminished thickening of inter-alveolar septa, as elucidated by morphological and histopathological analyses. Concurrently, a reduction in the expression levels of oxidative biomarkers, inflammatory factors, and fibrotic indicators was observed. Moreover, 16 S rRNA sequencing demonstrated that KPs pretreatment induced alterations in the relative abundances of gut microbiota, notably affecting Barnesiella_intestinihominis, Kineothrix_alysoides, and Clostridium_viride. CONCLUSIONS Kefir peptides exerted preventive effects, protecting mice against bleomycin-induced lung oxidative stress, inflammation, and fibrosis. These effects are likely linked to modifications in the gut microbiota community. The findings highlight the therapeutic potential of KPs in mitigating pulmonary fibrosis and advocate for additional exploration in clinical settings.

Abstract
The matrix metalloprotease A disintegrin and metalloprotease with thrombospondin motifs 1 (ADAMTS1) was reported to be involved in tumor progression in several cancer types, but its contributions appear discrepant. At present, the role of ADAMTS1 in oral squamous cell carcinoma (SCC; OSCC) remains unclear. Herein, The Cancer Genome Atlas (TCGA) database showed that ADAMTS1 transcripts were downregulated in head and neck SCC (HNSCC) tissues compared to normal tissues, but ADAMTS1 levels were correlated with poorer prognoses of HNSCC patients. In vitro, we observed that ADAMTS1 expression levels were correlated with the invasive abilities of four OSCC cell lines, HSC-3, SCC9, HSC-3M, and SAS. Knockdown of ADAMTS1 in OSCC cells led to a decrease and its overexpression led to an increase in cell-invasive abilities in vitro as well as tumor growth and lymph node (LN) metastasis in OSCC xenografts. Mechanistic investigations showed that the cyclic increase in ADAMTS1-L1 cell adhesion molecule (L1CAM) axis-mediated epidermal growth factor receptor (EGFR) activation led to exacerbation of the invasive abilities of OSCC cells via inducing epithelial-mesenchymal transition (EMT) progression. Clinical analyses revealed that ADAMTS1, L1CAM, and EGFR levels were all correlated with worse prognoses of HNSCC patients, and patients with ADAMTS1high/L1CAMhigh or EGFRhigh tumors had the shortest overall and disease-specific survival times. As to therapeutic aspects, we discovered that an edible plant-derived flavonoid, apigenin (API), drastically inhibited expression of the ADAMTS1-L1CAM-EGFR axis and reduced the ADAMTS1-triggered invasion and LN metastasis of OSCC cells in vitro and in vivo. Most importantly, API treatment significantly prolonged survival rates of xenograft mice with OSCC. In summary, ADAMTS1 may be a useful biomarker for predicting OSCC progression, and API potentially retarded OSCC progression by targeting the ADAMTS1-L1CAM-EGFR signaling pathway.

Abstract
BACKGROUND Among the novel robotic platforms, the Hugo RAS system is the second most studied platform, next to the da Vinci system, and we aim to address our experiences in radical prostatectomy (RP) with the Hugo RAS system. METHODS We recorded our first 12 cases of prostate cancer undergoing RP with the Hugo RAS system. The median console time was 145 min and median hospital stay was 7 days. Hedge' g was applied to search for the cut-off case in four parameters in surgeries. RESULTS Pre-console preparation was significantly improved after the first seven cases, and the console time was remarkably shortened after the first two cases. The intraoperative pause for trouble shooting was remarkably shortened after the first three cases. CONCLUSIONS We found that RP with the Hugo RAS system was feasible, and the learning curve was short as surgeons may benefit from the previous experience with the da Vinci system.

Abstract
BACKGROUND Kidney transplantation is the most important treatment for end-stage renal disease. Immunosuppressive therapies can prevent acute rejection for kidney transplant recipients. Tacrolimus is usually administered to prevent graft rejection after transplantation. Previous studies have indicated that once-daily tacrolimus may improve medication adherence. Therefore, this meta-analysis aimed to compare clinical outcomes between once-daily and twice-daily tacrolimus in de novo renal transplant patients. METHODS Eligible studies were identified from the Cochrane Library Database, PubMed, and Embase until July 2022. Those randomized controlled trials (RCTs) evaluating once-daily versus twice-daily tacrolimus formulations in de novo renal transplantation were included. A summary risk ratio (RR) and standardized mean difference (SMD) with the 95% confidence interval (CI) were estimated using a random-effects model. RESULTS In total, nine RCTs were included. There were no differences in biopsy-confirmed acute rejection rates between patients with once-daily and those with twice-daily tacrolimus (RR, 0.91; 95% CI, 0.73-1.13) in 12 months. Regarding renal function, there was no significant difference between the once-daily and twice-daily tacrolimus groups (SMD, -0.03; 95% CI, -0.12 to 0.07). In addition, the risk of graft failure, death, and adverse events in the first year was similar for the once-daily and twice-daily tacrolimus groups. CONCLUSION Our major findings suggest that de novo renal transplantation recipients receiving once-daily tacrolimus immediately after transplantation have comparable efficacy and safety with those recipients who received twice-daily tacrolimus. Therefore, once-daily tacrolimus medication can be an alternative for de novo renal transplantation recipients.

Abstract
PURPOSE This study investigated the oncological and functional surgical outcomes for patients with renal tumor who underwent robot-assisted partial nephrectomy (PN) by a single surgeon in Taiwan from 2006 to 2019. METHODS This retrospective study assessed patients who underwent robot-assisted PN for renal tumor. Patient data were analyzed for age, sex, body mass index, operative time and total ischemic time, surgical margin (positive/negative), and surgical complications. To evaluate functional and oncological outcomes, achievement of trifecta, and pentafecta criteria was used. Trifecta criteria were defined as a negative surgical margin, no postoperative complications, warm ischemia time <25 min. Pentafecta criteria were the trifecta criteria, >90% preservation of estimated glomerular filtration rate (eGFR) preservation, and no stage progression of chronic kidney disease at 1-year follow-up. RESULTS Of 101 patients who received robot-assisted PN, the most common type of renal tumor was clear cell renal cell carcinoma (RCC) (38%), followed by angiomyolipoma (26%). Patient characteristics were mean age 54.59 ± 13.8 years; mean RENAL Nephrometry score 6.63 ± 2.16; mean operative time 102.34 ± 50.06 min; and warm ischemia time 20.01 ± 14.12 min. The mean eGFR was 104.43 ± 31.73 mL/min/1.73 m2 preoperatively and 89.39 ± 32.3 mL/min/1.73 m2 postoperatively. Pathologic evaluation showed malignant tumors in 57 patients, among whom achievement of trifecta criteria occurred for 39 (68.42%) and pentafecta criteria for 18 (31.57%). Operation time was the only predictor for pentafecta achievement. CONCLUSION Robotic PN is a safe and effective approach for patients with renal tumor that can preserve most renal function and achieve oncological control. Pentafecta criteria can be used to more clearly define the surgical outcome of RAPN.

Abstract
OBJECTIVE This study aimed to explore the benefits of theranostic robot-assisted radical prostatectomy (T-RARP) for clinically highly suspicious prostate cancer (PCa) without proven biopsies. MATERIAL AND METHODS Between February 2016 and December 2020, we included men with clinically highly suspicious PCa in this study. They were assessed to have possible localized PCa without any initial treatments, and were categorized into previous benign biopsies or without biopsies. Furthermore, another group of malignant biopsies with RARP in the same time frame was adopted as the control group. The endpoints were to compare the oncological outcome and functional outcome between malignant biopsies with RARP and T-RARP. p < 0.05 was considered to be significant. RESULTS We included 164 men with proven malignant biopsies treated with RARP as the control group. For T-RARP, we included 192 men. Among them, 129 were preoperatively benign biopsies, and 63 had no biopsies before T-RARP. Approximately 75% of men in the T-RARP group had malignant pathology in their final reports, and the other 25% had benign pathology. T-RARP provides several oncological advantages, such as a higher initial pathological T stage, lower Gleason grade, and lower odds of positive surgical margins. However, the biochemical recurrence rates were not significantly decreased. From our cohort, T-RARP (odds ratio with 95% confidence interval; erectile recovery: 3.19 (1.84-5.52), p < 0.001; continence recovery: 2.25 (1.46-3.48), p < 0.001) could result in better recovery of functional outcomes than malignant biopsies with RARP. CONCLUSIONS For clinically highly suspicious PCa, T-RARP was able to detect around 75% of PCa cases and preserved their functional outcomes maximally. However, in 25% of men with benign pathology, approximately 6% would have incontinence and 10% would have erectile impairment. This part should be sufficiently informed of the potential groups considering T-RARP.

Abstract
BACKGROUND KH-type splicing regulatory protein (KHSRP, also called KSRP), a versatile RNA-binding protein, plays a critical role in various physiological and pathological conditions through modulating gene expressions at multiple levels. However, the role of KSRP in clear cell renal cell carcinoma (ccRCC) remains poorly understood. METHODS KSRP expression was detected by a ccRCC tissue microarray and evaluated by an in silico analysis. Cell loss-of-function and gain-of-function, colony-formation, anoikis, and transwell assays, and an orthotopic bioluminescent xenograft model were conducted to determine the functional role of KRSP in ccRCC progression. Micro (mi)RNA and complementary (c)DNA microarrays were used to identify downstream targets of KSRP. Western blotting, quantitative real-time polymerase chain reaction, and promoter- and 3-untranslated region (3'UTR)-luciferase reporter assays were employed to validate the underlying mechanisms of KSRP which aggravate progression of ccRCC. RESULTS Our results showed that dysregulated high levels of KSRP were correlated with advanced clinical stages, larger tumor sizes, recurrence, and poor prognoses of ccRCC. Neural precursor cell-expressed developmentally downregulated 4 like (NEDD4L) was identified as a novel target of KSRP, which can reverse the protumorigenic and prometastatic characteristics as well as epithelial-mesenchymal transition (EMT) promotion by KSRP in vitro and in vivo. Molecular studies revealed that KSRP can decrease NEDD4L messenger (m)RNA stability via inducing mir-629-5p upregulation and directly targeting the AU-rich elements (AREs) of the 3'UTR. Moreover, KSRP was shown to transcriptionally suppress NEDD4L via inducing the transcriptional repressor, Wilm's tumor 1 (WT1). In the clinic, ccRCC samples revealed a positive correlation between KSRP and mesenchymal-related genes, and patients expressing high KSRP and low NEDD4L had the worst prognoses. CONCLUSION The current findings unveil novel mechanisms of KSRP which promote malignant progression of ccRCC through transcriptional inhibition and post-transcriptional destabilization of NEDD4L transcripts. Targeting KSRP and its pathways may be a novel pharmaceutical intervention for ccRCC.

Abstract
Urothelial carcinoma (UC) could be observed in urinary bladder (UBUC) and upper urinary tracts (UTUC). In the National Comprehensive Cancer Network guidelines for bladder cancer, extirpative surgery is indicated in certain cases. However, some extreme cases might also need the extirpation of the majority of the urinary tract, which is called complete urinary tract extirpation (CUTE). We present a patient diagnosed with high-grade UBUC and UTUC. He underwent dialysis for end-stage renal disease (ESRD) at the same time. Considering his non-functional kidneys and removing his high-risk urothelium at the same time, we performed robot-assisted CUTE to extirpate both his upper urinary tracts, urinary bladder, and prostate. In our experience, the console time was not significantly elongated, and the perioperative course was uneventful. To our knowledge, this is the first case report adopting a robotic system in such an extreme case. We conclude that robot-assisted CUTE is worth further study regarding its oncological survival outcomes and perioperative safety in patients with ESRD on dialysis.

Abstract
Currently, the active surveillance of men with favorable intermediate-risk localized prostate cancer (PCa) is a longstanding controversy, in terms of their oncological outcomes, and radical prostatectomy would constitute a similar concern of overtreatment, regarding its functional outcomes. Thus, focal therapy could be considered in men belonging to favorable intermediate-risk group. Among all focal therapies, high-intensity focused ultrasound (HIFU) was the most studied methodology in clinical trials. Although HIFU provided better functional outcomes than radical prostatecomy, the oncological outcomes were inferior in men with intermediate-risk localized PCa. Two articles have been published discussing the feasibility and clinical outcomes of robot-assisted partial prostatectomy (RAPP), and both the functional and oncological outcomes were superior than those with HIFU. However, the rate of positive surgical margins (PSMs) was reported as high in the literature. Here, we present a case of favorable intermediate-risk localized PCa with an isolated tumor at the anterior apex. After reconstructing a personal three-dimensional (3D) image, we utilized it in a 3D image-guided precise excise, followed by intraoperative frozen specimen review. We found that this method may present a resolution to the high PSM rate documented in the current literature regarding RAPP. This method merits further study with a well-designed prospective study.

Abstract
Current literature has indicated that Peyronie's disease (PD) could be initiated by microtrauma and the subsequent inflammation episodes that follow. PD could be sorted into acute or chronic status, and it can differ when selecting the clinical therapeutics. PD would cause pain and penile deformity to diseased men and impair their erectile function. Occasionally, surgical revision of the penis might be needed to correct the penile curvature. We find that there are limited effective options of intra-lesion injections for the PD plaques. By searching the databases and screening the literature with the PRISMA 2020 guideline, we observed that several preclinical studies that applied stem cell therapy in treating PD were fruitful in the acute phase. Although in the chronic phase of PD, erectile parameters were not significantly improved, and therefore, future studies might be better elevated in certain aspects, such as the sites selected for harvesting stem cells or changing the centrifugation forces. In this review, we concluded the contemporary understanding of inflammatory microenvironments in PD, the stem cell therapy in PD, and our perspectives on future studies. We concluded that there may be great potential in stem cell therapy for treating both acute and chronic phases PD.

Abstract
Renal cell carcinoma (RCC) is one of the most lethal genitourinary malignancies with poor prognoses, since it is largely resistant to chemotherapy, radiotherapy, and targeted therapy. The persistence of cancer stem cells (CSCs) is the major cause of treatment failure with RCC. Recent evidence showed that dopamine receptor D2 (DRD2)-targeting antipsychotic drugs such as penfluridol exert oncostatic effects on several cancer types, but the effect of penfluridol on RCC remains unknown. Here, we uncovered penfluridol suppressed in vitro cell growth and in vivo tumorigenicity of various RCC cell lines (Caki-1, 786-O, A498, and ACHN) and enhanced the Sutent (sunitinib)-triggered growth inhibition on clear cell (cc)RCC cell lines. Mechanistically, upregulation of endoplasmic reticulum (ER) stress-induced unfolded protein response (UPR) was critical for autophagy-mediated apoptosis induced by penfluridol. Transcriptional inhibition of OCT4 and Nanog via inhibiting GLI1 was important for penfluridol-induced stemness and proliferation inhibition. The anticancer activities of penfluridol on ccRCC partially occurred through DRD2. In clinical ccRCC specimens, positive correlations of DRD2 with GLI1, OCT4, and Nanog were observed and their expressions were correlated with worse prognoses. Summarizing, DRD2 antagonists such as penfluridol induce UPR signaling and suppress the GLI1/OCT4/Nanog axis in ccRCC cells to reduce their growth through inducing autophagy-mediated apoptosis and stemness inhibition. These drugs can be repurposed as potential agents to treat ccRCC patients.

Background Inguinal hernia sac, extended tissue from peritoneum, gradually enlarged in size with hernia disease time and prolapsed tissue volume. We hypothesize that mesenchymal stem cells are present in the development of hernia sac. The current study aimed to test the hypothesis that hernia sac, which is often resected and discarded as medical waste, contains mesenchymal stem cells and thus might be a suitable source to harvest mesenchymal stem cells. Methods Between July 2019 and June 2020, 4 hernia sacs were resected during hernia surgery and then obtained for mesenchymal extraction using the Miltenyi gentleMACS Dissociator. The presence of mesenchymal stem cells was determined by the markers CD105, CD73, and CD90, with assessment of the expressions ≥ 95%, whereas markers CD45, CD34, CD11b, CD19, and HLA-DR were used to assess lack expression (≤ 2%). Moreover, von Kossa staining, Alcian blue staining, and Oil Red O staining were used to verify the cells' ability for differentiation. Results Cells retrieved from the hernia sacs displayed a spindle-shaped morphology and exhibited adherence to plastics. The cell surface immunophenotypic profile was confirmed using surface markers APC-A (CD73), FITC-A (CD90), and PerCP-Cy5-5-A (CD105), with results showing 100%, 100%, and 99.2%, respectively, strongly indicating the presence of mesenchymal stem cells. Moreover, staining of in vitro cell cultures showed in vitro differentiation of precursor cells into osteoblasts, adipocytes, and chondroblasts, suggesting positive differentiation ability and identification of mesenchymal stem cells. Conclusion Inguinal hernia sac is a novel source of mesenchymal stem cells that can be easily obtained and stored for future usage.

Abstract
ABSTRACT There is a lack of evidence supporting the association between carbon monoxide (CO) poisoning and acute kidney injury (AKI). Hence, the present study aimed to evaluate the association between CO poisoning and AKI.From 2000 to 2011, we identified patients diagnosed with CO poisoning from the inpatient claims data. Patients aged below 20 years, who had a history of chronic kidney disease or end-stage renal disease before the index date and had incomplete medical information were excluded. Control patients without CO poisoning were randomly selected from all National Health Insurance beneficiaries, and the same exclusion criteria were used. The control group was frequency matched to patients with CO poisoning based on age, sex, and year of CO poisoning diagnosis. Cox proportional hazards regression analyses were conducted to assess the effects of CO poisoning on the risk of AKI. The hazard ratios and 95% confidence interval (CI) were calculated in the models.Compared with the control cohort, patients with severe CO poisoning were 3.77 times more likely to develop AKI (95% CI = 2.20-6.46), followed by those with less severe CO poisoning (adjusted hazard ratio = 2.21, 95% CI = 1.61-3.03).The findings of this nationwide study suggest an increased risk of AKI in patients with CO poisoning.

Abstract
Monoacylglycerol lipase (MAGL), a serine hydrolase, converts endocannabinoid 2-arachidonoylglycerol (2-AG) to arachidonic acid (AA) and glycerol in the brain and plays a bidirectional role in controlling nueroinflammation. MAGL, involved in Alzheimer's and Parkinson's diseases, is a promising target for treatment of neurodegenerative disorders. However, the irreversible inhibitors of MAGL lead to the desensitization of CB1 receptors further impairing the benefits associated with the indirect CB1 stimulation. Therefore, development of potent reversible inhibitors from natural products (NPs) and traditional chinese medicines (TCMs) are safer and free from adverse side effects and feasible to avoid drawbacks which irreversible inhibitors cause. Here, we employed pharmacophore-based screening of drug candidates coupled with molecular docking, biochemical assay and Ligplot analyses to identify and characterize inhibitors targeting human MAGL (hMAGL). The built pharmacophore model, Phar-MAGL successfully identified inhibitors NP-2 (IC50 = 9.5 ± 1.2 μM), NP-5 (IC50 = 14.5 ± 1.3 μM), and NP-3 (IC50 = 15.2 ± 1.4 μM), which apparently attenuated the activities of hMAGL in vitro. The evident activities of the identified inhibitors against hMAGL showed that the pharmacophore model, Phar-MAGL is reliable and efficient in screening inhibitors against hMAGL. Our study successfully identified a natrual product inhibitor, NP-2 (8-PN), from the plant Humulus lupulus L. (hops) and its positive effects in neurogenesis and neurodifferentiation along with the evident inhibitory potency against hMAGL revealed the potential for further optimizing and developing into drugs to treat neuroinflammation, Alzheimer's and Parkinson's diseases.

Abstract
BACKGROUND/AIM Incisional hernia is a complication that occurs occasionally, and surgical intervention is required to prevent more severe sequela. While there are several options for management, robotic-assisted incisional repair has not been well discussed yet. We herein report a case series of 10 patients who underwent robotic-assisted incisional hernia repair (RIHR) after robotic-assisted radical prostatectomy (RARP). The aim of the study was to examine the feasibility of incisional hernia repair with da Vinci® robotics. PATIENTS AND METHODS We recruited patients from a group of 2,000 consecutive patients who underwent RARP from December, 2005 to June, 2020 by a single surgeon. Patient characteristics included age, body mass index (BMI), PSA level, pathology Gleason score, and pathology TNM staging. The variants regarding the patients' incisional hernia included incisional hernia occurrence time after RARP, defect size, operation time, console time, blood loss, and follow-up time after the herniation occurrence. Furthermore, we established a defect size of 3x2 cm2 as the cutoff value for using mesh reinforcement or not. RESULTS The mean defect area was 27.7 cm2, and the average operative time was 114.8 min, with a mean console time of 87 min. Blood loss was 32.5 ml, and the hospital stay for all patients was 3 days without complications. The mean follow-up period was 29.5 months, with no recurrence. CONCLUSION RIHR is a feasible surgical method that is not inferior to the traditional open or laparoscopic repair. Furthermore, RIHR can possibly lessen the burden of both the surgeon and patient.

Abstract
BACKGROUND Due to the difficulties in early diagnosing and treating hepatocellular carcinoma (HCC), prognoses for patients remained poor in the past decade. In this study, we established a screening model to discover novel prognostic biomarkers in HCC patients. METHODS Candidate biomarkers were screened by liquid chromatography with tandem mass spectrometry (LC-MS/MS) analyses of five HCC normal (N)/tumor (T) paired tissues and preliminarily verified them through several in silico database analyses. Expression levels and functional roles of candidate biomarkers were respectively evaluated by immunohistochemical staining in N/T paired tissue (n = 120) and MTS, colony formation, and transwell migration/invasion assays in HCC cell lines. Associations of clinicopathological features and prognoses with candidate biomarkers in HCC patients were analyzed from GEO and TCGA datasets and our recruited cohort. RESULTS We found that the transmembrane P24 trafficking protein 9 (TMED9) protein was elevated in HCC tissues according to a global proteomic analysis. Higher messenger (m)RNA and protein levels of TMED9 were observed in HCC tissues compared to normal liver tissues or pre-neoplastic lesions. The TMED9 mRNA expression level was significantly associated with an advanced stage and a poor prognosis of overall survival (OS, p = 0.00084) in HCC patients. Moreover, the TMED9 protein expression level was positively correlated with vascular invasion (p = 0.026), OS (p = 0.044), and disease-free survival (p = 0.015) in our recruited Taiwanese cohort. In vitro, manipulation of TMED9 expression in HCC cells significantly affected cell migratory, invasive, proliferative, and colony-forming abilities. CONCLUSIONS Ours is the first work to identify an oncogenic role of TMED9 in HCC cells and may provide insights into the application of TMED9 as a novel predictor of clinical outcomes and a potential therapeutic target in patients with HCC.

Abstract
The cytosolic non-receptor protein kinase, spleen tyrosine kinase (SYK), is an attractive drug target in autoimmune, inflammatory disorder, and cancers indications. Here, we employed pharmacophore-based drug screening combined with biochemical assay and molecular dynamics (MD) simulations to identify and characterize inhibitors targeting SYK. The built pharmacophore model, phar-TanI, successfully identified tanshinone (TanI (IC50 = 1.72 μM)) and its analogs (TanIIA (IC50 = 3.2 μM), ST32da (IC50 = 46 μM), and ST32db (IC50 = 51 μM)) which apparently attenuated the activities of SYK in vitro. Additionally, the MD simulations followed by Ligplot analyses revealed that TanI and TanIIA interfered SYK activity through binding deeply into the active site. Besides, TanI and TanIIA mainly interact with residues L377, A400, V433, M448, M450, A451, E452, L453, G454, P455, and L501, which are functional hotspots for structure-based inhibitor optimization against SYK. The structure-activity relationships (SAR) study of the identified SYK inhibitors demonstrated that the pharmacophore model, phar-TanI is reliable and precise in screening inhibitors against SYK. This study disclosed the structure-function relationships of tanshinones from Traditional Chinese Medicine (Danshen), revealing their binding site and mode of action in inhibiting SYK and provides applicability in developing new therapeutic agents.

Abstract
N-α-Acetyltransferase 10 protein (Naa10p) was reported to be an oncoprotein in androgen-dependent prostate cancer (PCa; ADPC) through binding and increasing transcriptional activity of the androgen receptor (AR). PCa usually progresses from an androgen-dependent to an androgen-independent stage, leading to an increase in the metastatic potential and an incurable malignancy. At present, the role of Naa10p in androgen-independent prostate cancer (AIPC) remains unclear. In this study, in silico and immunohistochemistry analyses showed that Naa10 transcripts or the Naa10p protein were more highly expressed in primary and metastatic PCa cancer tissues compared to adjacent normal tissues and non-metastatic cancer tissues, respectively. Knockdown and overexpression of Naa10p in AIPC cells (DU145 and PC-3M), respectively, led to decreased and increased cell clonogenic and invasive abilities in vitro as well as tumor growth and metastasis in AIPC xenografts. From the protease array screening, we identified a disintegrin and metalloprotease 9 (ADAM9) as a potential target of Naa10p, which was responsible for the Naa10p-induced invasion of AIPC cells. Naa10p can form a complex with ADAM9 to maintain ADAM9 protein stability and promote AIPC's invasive ability which were independent of its acetyltransferase activity. In contrast to the Naa10p-ADAM9 axis, ADAM9 exerted positive feedback regulation on Naa10p to modulate progression of AIPC in vitro and in vivo. Taken together, for the first time, our results reveal a novel cross-talk between Naa10p and ADAM9 in regulating the progression of AIPC. Disruption of Naa10p-ADAM9 interactions may be a potential intervention for AIPC therapy.

Abstract
BACKGROUND/AIM Expanded indications for patients with preoperatively suspected prostate cancer (PC) undergoing theranostic robotic-assisted laparoscopic radical prostatectomy (T-RARP) are reported. We aimed to build a nomogram of T-RARP to predict final pathologically proven PC. This study reviewed data of 153 patients that underwent T-RARP for suspected PC performed by the same surgeon. PATIENTS AND METHODS Patients' preoperative demographic and clinical characteristics included age, prostate-specific antigen (PSA) level, PSA density (PSAD), history of acute urinary retention (AUR), abnormal digital rectal examination (DRE) of the prostate, and Prostate Imaging Reporting and Data System (PI-RADS) classification at 3-T multiparametric magnetic resonance imaging (MRI). Logistic regression with backward elimination was used to select potential risk factors. RESULTS Based on Harrell's guidelines, we chose seven variables for our final model: Age, DRE corresponding with MRI, AUR, PSAD, prostate-specific antigen velocity (PSAV), PI-RADS, and biopsy pathology. A nomogram for prediction of adenocarcinoma was developed. The original C-index for the nomogram was 0.80 (95% confidence interval=0.74-0.89). The cut-off of the nomogram score for predicting PC was 50 (sensitivity=55.4%; specificity=91.9%). The receiver operating characteristic curve of the model analysis showed an area under the curve of 0.801. CONCLUSION A nomogram was produced using age, DRE-corresponding MRI, AUR, PSAD, PSAV, PI-RADS, and biopsy pathology. A preoperative nomogram prediction of prostate adenocarcinoma can help the patient and his family understand the possibility of PC and assist them in their decision-making.

Abstract
Xanthogranulomatous prostatitis is a rare occasion that mimics the prostate cancer in every aspect of clinical diagnosis. These two occasions require totally diverse therapeutics principles. Thus, emphasis should be exerted to distinguish them. The most precise tool to distinguish them is tissues’ evidence. However, another possible overlooking occasion is successive xanthogranulomatous prostatitis after complete remission under androgen deprivation therapy. This case demonstrated one metastatic prostate cancer with initial treatment of androgen deprivation therapy. PSA was suppressed to the lowest and then radical prostatectomy was performed. Hints from the specimen gave complete remission of cancer cell and development of xanthogranulomatous prostatitis.

Abstract
Lymphoepithelioma-like carcinoma, named after nasopharyngeal lymphoepithelioma and rarely seen at genitourinary malignancy, accounts for 1%–2% along the upper and lower urinary tract. For its rarity, no published guideline can be adhered to. Roles of surgery and chemotherapy are solid, and rich Programmed Death-Ligand 1 characteristics may furthermore light on the possible immunotherapy. This female case had it at both upper and lower urinary tract simultaneously. No involved regional lymph nodes and no distant metastasis were investigated. No adjuvant chemotherapy was given after robotics-assisted left nephroureterectomy and bladder cuff excision with partial cystectomy, and no recurrence was observed.

Abstract
In the present study, we have generated several H5N2 HA recombinant baculoviruses for production of a HA subunit vaccine against the lethal H5N2 avian influenza virus (AIV). The effective display of functional HA on the cell membrane and baculoviral envelope was examined. Our results reveal that chickens immunized with the chimeric AIV HA protein fused with the baculovirus gp64 cytoplasmic domain (CTD) induced higher HI titer. To further increase the expression level of the H5N2 AIV HA protein, the HA gene of H5N2 AIV was amplified and cloned into three novel baculovirus surface display vectors BacDual DisplayEGFP-2HA, BacDual DisplayEGFP-3HA, BacDual DisplayEGFP-4HA which contains multiple expression cassettes for higher level display of HA proteins on the cell membrane and baculovirus envelope. To determine the optimum conditions for producing HA protein, various MOI, infection times, and shaker times for virus transfection were tested. Our results reveal that the conditions of an MOI of 5, 3 day post infection, and 15 min of shaker time have higher efficiency for HA protein production. Our results reveal that the baculovirus surface display vector pBacDual DisplayEGFP-4HA increases significantly the expression level of the H5N2 AIV HA protein. Chickens that received two doses of BacDual DisplayEGFP-4HA cell lysates formulated with Montanide ISA70 adjuvant elicited efficient immunogenicity and had an average HI titer of 7 log2 at 2 weeks post-vaccination. Challenge studies revealed that vaccinated chickens with HI titers 5 log2 were completely protected against the lethal H5N1 AIV challenge. Furthermore, HI titers could be maintained at 5 log2 for 20 weeks for laying hens. This study suggests that the HA protein expression from the baculovirus surface display system could be a safe and efficacious subunit vaccine for chickens.

Abstract
Background: To evaluate the efficacy of early dutasteride administration in patients with a detectable prostate-specific antigen (PSA) levels after robot-assisted radical prostatectomy (RARP). Methods: We retrospectively analyzed RARP patients whose pathological stage is T2a to T3b without lymph node or distant metastasis from 2007 to 2017. All patients received a daily dose of 0.5 mg of dutasteride when post-RARP PSA levels were increasing but had not achieved biochemical recurrence. PSA levels were monitored every 3 months after dutasteride administration. None of the patients received radiotherapy (RT) or androgen-deprivation therapy (ADT) before taking dutasteride. All follow-ups were begun from RARP to January 2019 or to the date of RT/ADT. Results: Thirty-five patients were included in this analysis. The median followed up was 53.6 months. Twenty-two patients (62.9%) showed a PSA response in which the PSA decreased more than 10% at the first follow-up after dutasteride administration. The Pathological stage > T2 (p = 0.012) and positive surgical margin (p = 0.046) were prognostic factors for a PSA response. Twenty-three out of 35 included patients (65.7%) did not require further RT/ADT. The significant risk factor was the PSA level (p = 0.011) at the beginning of dutasteride treatment. The cut-off value of the PSA level to avoid further RT/ADT was 0.195 ng/ml. Conclusions: Early dutasteride administration showed a significant decline in the PSA levels of patients with pathology stage >T2 and positive surgical margin in our retrospective hypothesis-generating study. If dutasteride was provided before the PSA value increased to 0.195 ng/ml after RARP, it would reduce the probability of acquirement of RT/ADT.

Abstract
The prevalence of temporomandibular disorder (TMD) among elderly people with Parkinson’s disease (PD) is relatively high, but a population-based study of the relationship between PD and TMD is still lacking. This study, therefore, sought to investigate the association between TMD and PD by using data for one million randomly sampled beneficiaries of Taiwan’s National Health Insurance program, including 6,185 PD patients who were matched through propensity score matching with 18,555 non-PD patients. Both the PD and non-PD cohorts were followed until death, any diagnosis of TMD, or December 31, 2013, whichever occurred first. Each diagnosis of TMD was made by a qualified physician according to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM), using the diagnosis codes 524.60, 524.62, 524.63, and 524.69 while excluding tooth abscess, wisdom tooth eruption, herpes zoster and postherpetic neuralgia, mastoiditis, otitis externa, otitis media, parotitis, sialadenitis, and trigeminal neuralgia. We used Cox proportional hazard regression models to calculate the relative risk of TMD and found a 2.11-fold (95% CI: 1.35–3.30) increased risk of TMD overall in the PD group compared with the non-PD group. Stratified by follow-up period, there was a 4.25-fold (95% CI: 1.51–11.93) increased risk in the PD group in the first year after the initial PD diagnosis and a 3.88-fold (95% CI: 1.33–11.28) increased risk in the second year. Over the long-term (>5 years), PD was significantly associated with an increased risk of TMD. These findings suggest that it is important to closely monitor the temporomandibular joint health of PD patients.

Abstract
Increasing evidence shows that dysregulated expression of long non-coding (lnc)RNAs can serve as diagnostic or prognostic markers in urothelial cell carcinoma (UCC), the most common pathological type of bladder cancer. lncRNA HOX transcript antisense RNA (HOTAIR) was shown to promote tumor progression and be associated with a poor prognosis in multiple cancers including bladder cancer. Polymorphisms of HOTAIR were recently linked to a predisposition for diverse malignancies. Herein we conducted a case-control study to evaluate whether genetic polymorphisms of HOTAIR were associated with UCC risk and clinicopathologic characteristics. Four loci (rs920778 T>C, rs1899663 G>T, rs4759314 A>G, and rs12427129, C>T) of HOTAIR were genotyped by a TaqMan allelic discrimination method in 431 cases and 862 controls. We found that female patients who carried AG + GG genotype of rs4759314 were associated with an increased UCC risk after controlling for age and tobacco consumption (adjusted odds ratio (AOR) = 1.92, 95% confidence interval (CI): 1.01–3.64, p = 0.047) and a lower overall survival rate (p = 0.008). Moreover, patients with a smoking habit or younger age (≤65 years), who had at least one T allele of HOTAIR rs12427129 were at a higher risk of developing advance tumor T satge (p = 0.046), compared to those patients with CC homozygotes. In contrast, rs920778 C allele carriers were negatively correlated with the development of lymph node metastasis (OR = 0.51, 95% CI: 0.28–0.94, p = 0.031). Further analyses of clinical datasets revealed correlations of the expression of HOTAIR with tumor metastasis and a poor survival rate in patients with UCC. Our results verified the diverse impacts of HOTAIR variants on UCC susceptibility and clinicopathologic characteristics.

Abstract
Background: Several reports have revealed the presence of lymph nodes in the prostatic anterior fat pad (PAFP). To date, no study has described the characteristics of Taiwanese patients harboring PAFP lymph nodes with metastatic prostate cancer involvement. Method: Between December 2006 and May 2015, a total of 849 consecutive patients underwent robot-assisted laparoscopic radical prostatectomy with PAFP dissection. Pathological examination of the dissected PAFP was conducted to assess the presence of lymphoid tissue and prostate cancer involvement. Results: Of the 849 patients, 76 (9.0%) had 1-3 PAFP lymph nodes. Moreover, 11 (1.3%) of the 76 patients had positive lymph node metastases of prostate cancer in the PAFP; 5 (0.6%) of the 11 patients, who had negative pelvic lymph node involvement, were upstaged because of positive metastases in PAFP lymph nodes. Among the 76 patients having PAFP lymph nodes, metastatic lymph nodes were associated with the clinical T stage, preoperative Gleason score, pathological T stage, and pathological N stage (p < 0.001). Patients with pathological seminal vesicle invasion and a higher surgical Gleason score also exhibited PAFP lymph node metastases (p < 0.005). Conclusion: Our data show that 9.0% of patients had PAFP lymph nodes and that 1.3% had prostate cancer metastases. Additionally, 0.6% of patients were upstaged because of positive metastases in PAFP lymph nodes. Because of the pathological analysis of the PAFP, a few patients were upstaged. Thus, routine pathological analysis of the PAFP should only be conducted for those with higher preoperative prostate-specific antigen, higher Gleason score, and advanced T stage observations.

Abstract
Dopamine receptor D2 (DRD2) is overexpressed in several kinds of cancers and was correlated with the prognosis of these cancers. Polymorphisms within the DRD2 gene were shown to be associated with lung and colon cancers. The purpose of this study was to explore effects of DRD2 gene polymorphisms on the susceptibility to and clinicopathological characteristics of urothelial cell carcinoma (UCC). In total, 369 patients diagnosed with UCC and 738 healthy controls were enrolled to analyze DRD2 genotypes at four loci (rs1799732, -141C>del; rs1079597, TaqIB; rs6277, 957C>T; and rs1800497, TaqIA) using a TaqMan-based real-time polymerase chain reaction (PCR). We found a significantly lower risk for UCC in individuals with the DRD2 rs6277 CT genotype compared to those with the wild-type CC genotype (adjusted odds ratio (AOR)=0.405, 95% confidence interval (CI): 0.196~0.837, p=0.015). In 124 younger patients (aged < 65 years) of the recruited UCC cohort, patients who carried at least one T allele of DRD2 rs1800497 were at higher risk (AOR=2.270, 95% CI: 1.060~4.860, p=0.033) of developing an invasive stage (pT2~pT4). In 128 female patients of the recruited UCC cohort, patients who carried at least one deletion allele of DRD2 rs1799732 showed a higher incidence of having an invasive stage (AOR=2.585, 95% CI: 1.066~6.264, p=0.032) and a large tumor (AOR=2.778, 95% CI: 1.146~6.735, p=0.021). Further analyses of The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) datasets revealed correlations of the expression of DRD2 with an invasive tumor, tumor metastasis, and the lower survival rate in patients with UCC. Our findings suggest that DRD2 levels might affect the progression of UCC, and the polymorphisms rs6277, rs1800497, and rs1799732 of DRD2 are probably associated with the susceptibility and clinicopathologic development of UCC in a Taiwanese population.

Abstract
MicroRNA-184 suppresses cell growth and survival via targeting c-Myc and Bcl- 2. We recently reported that miR-184 promotes tumor progression in non-small cell lung cancer via targeting CDC25A and c-Myc. We here hypothesized that miR-184 could be down-regulated by E6 oncoprotein to confer cisplatin resistance in NSCLC. Human papillomavirus (HPV) 16-positive lung cancer TL-1 and cervical cancer SiHa cells compared with HPV16-negative TL-10 and C33A cells were enrolled for E6 manipulation. MiR-184 expression levels were increased by E6-knockdown in TL-1 and SiHa cells, but decreased by E6-overexpression in TL-10 and C33A cells. The MTT assay showed that the inhibition concentration of cisplatin yielding for 50% cell viability was dependent on miR-184 levels. Bcl-2 de-targeted by E6-mediated miR- 184 reduction was responsible for cisplatin resistance. Luciferase reporter assay and real- time PCR analysis indicated that the miR-184 promoter activity and its expression were modulated by E6 and/or p53 manipulation. Chromatin immunoprecipitation (ChIP) assay confirmed that p53 was bound onto the miR-184 promoter and its binding activity was modulated by E6 and/or p53 manipulation. Among patients, high miR184 and high Bcl-2 mRNA expression was more commonly occurred in E6- positive tumors than in E6-negative tumors. Fifty-nine out of 136 patients receiving cisplatin-based chemotherapy were available for the retrospective study. Patients with low-mR-184, E6-positive, high-Bcl-2 tumors, and both combinations were more prevalently occurred unfavorable response to cisplatin-based chemotherapy than their counterparts. In conclusion, a decrease in miR-184 level by E6 oncoprotein may predict unfavorable response to cisplatin-based chemotherapy in HPV-infected NSCLC patients via increasing Bcl-2 expression.

Abstract
BACKGROUND Urothelial carcinoma (UC) is derived from the urothelium of the urinary tract, and includes cancers of the bladder, renal pelvis and ureter. The aim of this study was to investigate the clinical and demographic features among patients with bladder cancer and urothelial carcinoma of the upper urinary tract (UTUC) in Taiwan. METHODS The present study recruited a total of 736 histopathologically confirmed UC cases, which consisted of 470 bladder cancer and 266 UTUC between September 1998 and December 2009. Clinical and demographic features were collected by an interview utilizing a structured questionnaire, and supplemented by medical chart review. This study was approved by institutional review boards of the collaborating hospitals. The multivariate Cox proportional hazards model was performed to investigate prognostic factors for disease-free survival (DFS) and overall survival (OS). All statistical analyses were performed using the Statistical Analysis Software for Windows, version 9.1 (SAS Institute, Cary, NC, USA). RESULTS UTUC patients had higher proportions of advanced clinical stage (T2-4) and poor cell differentiation (G3). Bladder cancer patients with advanced clinical stages (T2-3 and T4) had increased risks of poorer OS (hazard ratio, HR = 1.7 and 3.9, respectively). UTUC patients with the advanced clinical stage (T4) had a significantly greater risk of poorer OS (HR = 8.7). Bladder cancer patients with a high grade (G2-3) had a significantly increased risk of poorer OS (HR = 3.8). CONCLUSION Based on the limited parameters and heterogeneous data, the present study merely observed that bladder cancer and UTUC patients with the higher tumor stage have a significant increased risk of poor overall survival. Therefore, the causal mechanisms of UC prognosis remained to be further explored in a larger population.

Abstract
AIM To report the outcomes of salvage robot-assisted radical prostatectomy (S-RaRP). PATIENTS AND METHODS Fourteen patients underwent S-RaRP. The mean initial prostatic-specific antigen level was 14.3 ng/ml and mean Gleason score was 6.93. Initial definitive treatment was external irradiation in 11 cases, cyberknife in two, and high-intensity focused ultrasound in one. Time from definitive treatment to S-RaRP was a mean of 36.5 months. RESULTS The mean console time was 134.9 min and blood loss was 99.6 ml. Stage pT2N0, T3N0, and T3N1 were found in eight, four, and two cases, respectively. A positive surgical margin was found in 21.4% (3/14) of the patients. The continence rate was 71.4% (10/14). Mild stress urinary incontinence (one or two pads/day) was noted in 28.6% (4/14) of patients. Biochemical recurrence-free status was noted in 11 (78.5%) patients with a mean follow-up of 32.4 months. CONCLUSION S-RaRP is feasible with a low complication rate, good continence rate, and an acceptable potency rate. The short-term oncological outcomes are encouraging.

Abstract
BACKGROUND/AIM Expanded indications are not yet reported for robotic-assisted laparoscopic radical prostatectomy (RARP) performed by experienced surgeons for patients with preoperative suspicion of prostate cancer. We report our experience with 55 cases of prophylactic RARP for preoperative suspicion of prostate cancer, including postoperative pathological characteristics and outcomes. PATIENTS AND METHODS This retrospective study reviewed data of a subset of 55 consecutive patients among 1,060 patients who underwent RARP for preoperative suspicion of prostate cancer. Pathological characteristics and outcomes of patients with suspected prostate cancer were analyzed and preoperative, intraoperative and postoperative parameters were compared between three groups. Patients were stratified by final pathology reports of RARP specimens: Group I: Prostate cancer, N=22 (40%); group II: abnormal (prostate intraepithelial neoplasia; atypical small acinar proliferation), N=18 (32.7%); and group III: benign (nodular hyperplasia or inflammation), N=15 (27.3%). RESULTS Mean preoperative prostate-specific antigen (PSA) was 16.04±2.21 ng/ml. Twenty-two patients with adenocarcinoma had pathology stage pT2a/T2b/ T2c/T3a/T3b (6/7/2/6/1 patients, respectively), with positive surgical margins in 18.2% (4/22). Preoperative incidence of PSA velocity >0.75 ng/ml/yr was significantly higher in group I than in groups II and III (81.8% vs. 38.9% vs. 33.3%, p=0.004). Predictive parameters of prostate cancer showed that PSA velocity (>0.75 vs. ≤0.75 ng/ml/yr) had crude odds ratio of 9.0 for group I vs. group III, p=0.005. Posteperatively, statistically significant improvements were found in uroflow rate, post-voiding residual urine and symptom scores (all p<0.0001). CONCLUSION Prophylactic RARP with bilateral neurovascular bundle preservation performed by experienced surgeons is a safe and viable option for preoperative suspicion of prostate cancer.

Abstract
Melatonin counteracts tumor occurrence and tumor cell progression in several cancer types in vitro and in vivo. It acts predominantly through its melatonin receptor type 1A (MTNR1A), and genetic variations of MTNR1A affect the susceptibility several diseases and cancer. The purpose of this study was to explore the effect of MTNR1A gene polymorphisms on the susceptibility to and clinicopathological characteristics of urothelial cell carcinoma (UCC). We recruited 272 patients with UCC and 272 normal controls to analyze three common single-nucleotide polymorphisms (SNPs) (rs2119882, rs13140012, and rs6553010) of MTNR1A related to cancer risk and clinicopathological relevance according to a TaqMan-based real-time polymerase chain reaction (PCR). We found that these three SNPs of MTNR1A were not associated with UCC susceptibility. However, patients with UCC who had at least one G allele of MTNR1A rs6553010 (in intron 1) were at higher risk (1.768-fold, 95% confidence interval: 1.068~1.849) of developing an invasive stage (p < 0.026), compared to those patients with AA homozygotes. In conclusion, polymorphic genotypes of rs6553010 of MTNR1A might contribute to the ability to predict aggressive phenotypes of UCC. This is the first study to provide insights into risk factors associated with intronic MTNR1A variants in the clinicopathologic development of UCC in Taiwan.

Abstract
AIM Tuberous sclerosis complex (TSC) presents with multisystem benign neoplasm induced by dysregulation of the mammalian target of rapamycin pathway. This study aimed to examine the effects of oral everolimus at either 2.5 or 5.0 mg daily on the treatment of TSC-associated renal angiomyolipoma (AML). METHODS Between July 2012 and August 2015, patients with TSC-associated renal AML were selected for everolimus therapy protocol. An oral everolimus starting dose at 2.5 mg was administered daily, and was gradually increased to 5.0 mg daily. All patients were evaluated using magnetic resonance imaging or computed tomography scanning at baseline, 12, 24, and 36 months after the start of treatment for measuring the changes of renal AML mass volume. RESULTS Eight patients were finally enrolled for analysis in this study. Everolimus treatment had a statistically significant effect on the renal AML volume reduction during follow-up (P < 0.05). Renal AML mass volume reduction rates were 10.5-45.3% in four patients with everolimus 2.5 mg and 40.7-73.1% in four patients with everolimus 5.0 mg daily; the difference was statistically significant between the two groups (P < 0.05). Longitudinal follow-up for response to everolimus showed volume reduction rates to be around 10.5-73.1% in the initial 6-24 months after everolimus treatment, which remained stable during follow-up up to 36 months. CONCLUSION The results suggest that an oral everolimus is effective and provides a non-invasive way to treat TSC-associated renal AML, and patients are likely to require maintenance therapy to continue to derive benefit.

Abstract
Abstract
Previous studies have investigated the association between TNF-α-308 G/A polymorphism and bladder cancer risk in various populations. However, these findings remain inconclusive. Therefore, we performed a meta-analysis to explore the relationship between TNF-α-308 G/A polymorphism and bladder cancer risk. A literature search in PubMed was performed to select eligible studies regarding the association between TNF-α-308 G/A polymorphism and bladder cancer risk. The strength of risk under fixed- and random- effects models were estimated using the odds ratios (ORs) with 95% confidence intervals (CIs). We identified 7 case-control studies including 1153 cases and 1587 controls were included in the present meta-analysis. Compared with subjects carrying the G/G genotype of TNF-α-308 G/A polymorphism, those with the A/A and G/A genotypes had non-significant bladder cancer risks under the fixed effects model (OR = 1.037) and the random effects model (OR = 1.012). In the recessive model, subjects with the A/A genotype had an increased bladder cancer risk (OR = 1.875) compared with those carrying the G/A and G/G genotypes of TNF-α-308 G/A polymorphism. The major finding of this meta-analysis suggest that TNF-α-308 G/A polymorphism is correlated with the risk of bladder cancer in Asian population under the recessive model. We should further investigate the joint effects of environmental risk factors and TNF-α-308 G/A polymorphism on bladder cancer risk.

Abstract
Background Cystic hygroma is a rare benign abnormality of the lymphatic system generally occurring in young children less than 2 years old. The standard transcervical surgical treatment of cystic hygroma may often leave a permanent scar in the neck region. Case presentation We report a case of cystic hygroma in a 19-month-old Asian baby girl successfully treated with robot-assisted excision through a hairline neck-lift approach. We present the use of the Yang’s retractor as an instrumental advancement to this surgical approach. Conclusions Treatment options for cystic hygroma may be surgical or nonsurgical. We report a case of cystic hygroma in a 19-month-old child successfully treated with robot-assisted excision through a small concealed retroauricular hairline approach. This is the first report in the medical literature of treating cystic hygroma with a minimally invasive robot-assisted excision via a small, concealed, hairline incision.

Prevention and Management of Complications During Robotic-assisted Laparoscopic Radical Prostatectomy Following Comprehensive Planning: A Large Series Involving a Single Surgeon.

Abstract
AIM To report a series of 1,000 patients treated by a single surgeon using robotic-assisted laparoscopic radical prostatectomy (RALP) and to show how to prevent and manage complications of the procedure. PATIENTS AND METHODS Complication rates were prospectively assessed in a series of 1,000 consecutive patients who underwent RALP (group I, cases 1-200; IIa, 201-400; IIb, 401-600; IIIa, 601-800; and IIIb, 801-1000). Preoperative evaluation focused on patients' history of gout, use of drugs that can influence clotting time, and cardiopulmonary problems. Magnetic resonance imaging (MRI) was routinely performed. Operative difficulty was assessed based on the following variables: neoadjuvant hormonal therapy (NHT), obesity [body mass index (BMI) >30 kg/m(2)], prostate volume >70 g, presence of a large median lobe with intravesical protrusion >1 cm, previous transurethral resection of the prostate, previous pelvic surgery, previous extended pelvic lymph node dissection (EPLND), and salvage robotic radical prostatectomy (SRP). RESULTS Operative difficulty tended to increase significantly with greater age, higher American Society of Anesthesiologists' anesthetic/surgical risk class scores, increased BMI, and more advanced clinical stage. The number of cases with NHT, obesity, previous pelvic surgery, EPLND, and SRP significantly increased from early to later groups of patients. Conversely, significantly less blood loss occurred in later groups of patients (group I, 179 ml to 97 ml in group IIIb; p<0.001). The need for blood transfusions gradually reduced from 3.5% to 0.5% in groups I and IIIb, respectively (p=0.022). The total complication rate was 6.4% (64/1,000; surgical/medical=5%/1.4%). Complication rates decreased significantly: 12%, 6%, 6%, 4%, and 4% in groups I, IIa, IIb, IIIa, and IIIb, respectively (p=0.003). The most common complications were blood transfusion and bowel problems (11/1,000=1.1%). CONCLUSION Assessed in terms of groups of 200 cases, the surgeon's learning curve for RALP showed significantly fewer complications even as the operative difficulty of cases increased. The keys to preventing complications were meticulous preoperative evaluation of patients, MRI planning, and a dedicated robotic team for performing RALP. Early diagnosis and management of complications are paramount in patients who present any deviation from the normal postoperative course and clinical care pathway.

Abstract
Nrf2 is a key transcription factor for genes coding for antioxidants, detoxification enzymes, and multiple drug resistance and it also confers resistance to anticancer drugs. Here, we hypothesized that mutant p53 could upregulate Nrf2 expression at the transcriptional level, thereby conferring cisplatin resistance in non-small cell lung cancer (NSCLC). Luciferase reporter assays and real-time PCR analysis indicated that the Nrf2 promoter activity and its mRNA levels were markedly suppressed by wild-type p53, but not by mutant p53. Chromatin immunoprecipitation (ChIP) further confirmed that wild-type p53 binds at the p53 putative binding site to block Sp1 binding to the Nrf2 promoter and consequently to suppress the Nrf2 promoter activity. The MTT assay indicated that an increase in Nrf2 expression by mutant p53 is responsible for cisplatin resistance. Among the Nrf2 downstream genes, Bcl-2 and Bcl-xL contribute more strongly to Nrf2-mediated cisplatin resistance when compared with heme oxygenase 1 (HO-1). Cox regression analysis showed that patients with high-Nrf2, high-Bcl-2, high-Bcl-xL mRNA tumors were more commonly occurred unfavorable response to cisplatin-based chemotherapy than their counterparts. The prognostic significance of Nrf2 mRNA levels on OS and RFS was also observed in patients who have received cisplatin-based chemotherapy, particularly in p53-mutant patients. Collectively, mutant p53 may confer cisplatin resistance via upregulation of Nrf2 expression, and Nrf2 mRNA level may predict chemotherapeutic response and outcomes in NSCLC.
