Abstract
PURPOSE This study aimed to investigate dynamic change of permeability of blood-labyrinth barrier (BLB) after noise exposure and its effect on the drug delivery efficiency of systemic administration. METHODS Gadopentetate dimeglumine (Gd-DTPA) and dexamethasone (DEX) were used as tracers, and magnetic resonance imaging (MRI) and immunofluorescence were used to observe the change of the BLB after strong noise exposure in guinea pigs. High-performance liquid chromatography-mass spectrometry (LC-MS) was used to observe the effect of the breakdown of BLB after noise exposure on the drug delivery efficiency of intravenous DEX. The guinea pigs were divided into 6 groups: normal group (N), 1, 3, 5, 8, and 12 days after noise exposure groups (P1, P3, P5, P8, P12), with 5 animals in each group. RESULTS The BLB changes dynamically after noise exposure. Increased permeability of the blood-endolymph barrier, the endolymph-perilymph barrier, and the blood-nerve barrier was observed at days 1-3, 1-5, and 1-8, respectively, after noise exposure in guinea pigs. Higher drug concentration in the cochlear tissue was obtained by intravenous administration of DEX in guinea pigs during the time window of increased permeability of the BLB. CONCLUSION After noise exposure, the increased BLB permeability makes it easier for drugs to enter the inner ear from blood. In guinea pigs, 1-8 days after strong noise exposure, the drug delivery efficiency of systemic administration increased. After 8 days, the efficiency gradually returned to normal level. 1-8 days after noise exposure may be the best intervention time for systemic administration. LEVEL OF EVIDENCE NA Laryngoscope, 134:2377-2386, 2024.

Abstract
PURPOSE Intraductal carcinoma of the prostate (IDC-P) is a histological subtype that differs from conventional acinar adenocarcinoma in terms of its origin, appearance, and pathological features. For IDC-P, there is currently no recognized best course of action, and its prognosis is unclear. The goal of this study is to analyze independent prognostic factors in IDC-P patients and to develop and validate a nomogram to predict overall survival (OS) and cancer-specific survival (CSS). METHODS Clinical data for IDC-P patients were collected from the Surveillance, Epidemiology, and End Results database. To identify the independent variables influencing prognosis, multivariate Cox regression analysis was performed. A nomogram model was created utilizing these variables after comparing the variations in OS and CSS among various subgroups using Kaplan‒Meier curves. Internal validation of the nomograms was verified using the bootstrap resampling method. RESULTS The study included 280 IDC-P patients in total. Marital status, summary stage, grade, and the presence of lung metastases were significant factors impacting OS, and CSS was significantly influenced by marital status, summary stage, AJCC stage, the presence of lung metastases, the presence of bone metastases, and PSA according to univariate and multivariate Cox regression models (P < 0.05). Nomogram models were created to estimate OS and CSS using these parameters. The OS prediction model's C-index was 0.744, whereas the CSS prediction model's C-index was 0.831. CONCLUSION We developed and verified nomogram models for the prediction of 1-, 3-, and 5-year OS and CSS in patients with IDC-P. These nomograms serve as a resource for evaluating patient prognosis, therapy, and diagnosis, ultimately improving clinical decision-making accuracy.

Abstract
BACKGROUND Age-related hearing loss (ARHL) is a major cause of chronic disability among the elderly. Individuals with ARHL not only have trouble hearing sounds, but also with speech perception. As the perception of auditory information is reliant on integration between widespread brain networks to interpret auditory stimuli, both auditory and extra-auditory systems which mainly include visual, motor and attention systems, play an important role in compensating for ARHL. OBJECTIVES To better understand the compensatory mechanism of ARHL and inspire better interventions that may alleviate ARHL. METHODS We mainly focus on the existing information on ARHL-related central compensation. The compensatory effects of hearing aids (HAs) and cochlear implants (CIs) on ARHL were also discussed. RESULTS Studies have shown that ARHL can induce cochlear hair cell damage or loss and cochlear synaptopathy, which could induce central compensation including compensation of auditory and extra-auditory neural networks. The use of HAs and CIs can improve bottom-up processing by enabling 'better' input to the auditory pathways and then to the cortex by enhancing the diminished auditory signal. CONCLUSIONS The central compensation of ARHL and its possible correlation with HAs and CIs are current hotspots in the field and should be given focus in future research.

Abstract
Despite the distortion of speech signals caused by unavoidable noise in daily life, our ability to comprehend speech in noisy environments is relatively stable. However, the neural mechanisms underlying reliable speech-in-noise comprehension remain to be elucidated. The present study investigated the neural tracking of acoustic and semantic speech information during noisy naturalistic speech comprehension. Participants listened to narrative audio recordings mixed with spectrally matched stationary noise at three signal-to-ratio (SNR) levels (no noise, 3 dB, -3 dB), and 60-channel electroencephalography (EEG) signals were recorded. A temporal response function (TRF) method was employed to derive event-related-like responses to the continuous speech stream at both the acoustic and the semantic levels. Whereas the amplitude envelope of the naturalistic speech was taken as the acoustic feature, word entropy and word surprisal were extracted via the natural language processing method as two semantic features. Theta-band frontocentral TRF responses to the acoustic feature were observed at around 400 ms following speech fluctuation onset over all three SNR levels, and the response latencies were more delayed with increasing noise. Delta-band frontal TRF responses to the semantic feature of word entropy were observed at around 200 to 600 ms leading to speech fluctuation onset over all three SNR levels. The response latencies became more leading with increasing noise and decreasing speech comprehension and intelligibility. While the following responses to speech acoustics were consistent with previous studies, our study revealed the robustness of leading responses to speech semantics, which suggests a possible predictive mechanism at the semantic level for maintaining reliable speech comprehension in noisy environments.

Abstract
The vascular and morphological features of tumors are important predictors of the nature, grade, and stage of various cancers. However, this association has not been tested in bladder cancer. The aim of our study was to investigate the correlation between the morphological characteristics of tumor vessels and the nature, stage and grade of bladder cancer. Between November 2021 and March 2023, we prospectively collated clinical information and cystoscopy information from a series of patients with bladder cancer. Univariate and multivariate logistic regression analysis were used to identify independent risk factors for the nature, grade and stage of bladder cancer. Our analysis showed that cauliflower-like tumors, dotted vessels, and circumferential vessels were independent risk factors for bladder cancer. Reticular vessels were an independent risk factor for high-grade bladder cancer. Thick branching vessels in bladder tumors, along with a wide base, were independent risk factors for the invasion of bladder cancer into the lamina propria. Primary diagnosis, lesion location (beside the left ureteral orifice) and obscure lesion boundaries were all identified as independent risk factors for muscle invasive bladder cancer.

Abstract
PURPOSE At present, the prediction of bladder tumor nature during cystoscopy is partially dependent on the clinician's own experience. Subjective factors may lead to excessive biopsy or delayed treatment. The purpose of our study is to establish a reliable model for predicting the nature of bladder tumors using narrow band imaging. METHODS From November 2021 to November 2022, the clinical data of 231 patients who required a cystoscopy were prospectively collected at our center. Cystoscopy was performed in 219 eligible patients, in which both tumor and vascular morphology characteristics were recorded. Pathological results were used as the diagnostic standard. A logistic regression analysis was used to screen out factors related to tumor pathology. Bootstrap resampling was used for internal validation. A total of 71 patients from four other centers served as an external validation cohort. RESULTS The following diagnostic factors were identified: tumor morphology (cauliflower-like or algae-like lesions), vascular morphology (dotted or circumferential vessels), tumor boundary (clear or unclear), and patients' symptoms (gross hematuria) and were included in the prediction model. The internal validation results showed that the area under the curve was 0.94 (95% CI 0.92-0.97), and the P value from the goodness-of-fit test was 0.97. After external validation, the results showed the area under the curve was 0.89 (95% CI 0.82-0.97) and the P value of the goodness-of-fit test was 0.24. CONCLUSION A diagnostic prediction nomogram was established for bladder cancer. The verification results showed that the prediction model has good prediction performance.

Abstract
Objective The mechanism by which migraines produce inner ear-related symptoms is not well understood. Previous studies have found that the latency of auditory brainstem response (ABR) in animal models of migraine has changed, but the threshold has not changed significantly. Therefore, it is necessary to establish a better animal model with both migraine and hearing loss to explore the relationship between migraine and auditory function deeply. Methods In this study, the rat model of migraine was induced by postauricular injection of nitroglycerin (NTG), and the effect on the auditory function of the inner ear was explored by comparing with intraperitoneal injection of nitroglycerin. The rats were given the drug repeatedly on alternate days, a total of 5 dosing, with the body weight monitored during the drug administration. The tactile threshold of the rats' forepaw was measured using von-Frey filaments and auditory function was assessed by ABR. Results The results showed that the baseline tactile threshold of rats gradually decreased during the modeling process, and hyperalgesia appeared. Postauricular injection of NTG did not affect the weight gain of rats, while intraperitoneal injection of NTG showed slow or even negative weight gain. The ABR threshold of Click, 4 and 8 kHz of postauricular NTG injection rats increased, the latency was prolonged, and the ABR threshold in the right ear was higher than that in the left ear. Conclusions We demonstrated that postauricular injection of nitroglycerin may be safer and more effective than intraperitoneal injection of nitroglycerin in the process of creating rat migraine model without affecting the weight gain. Postauricular injection of nitroglycerin has more damage to the auditory function of rats. Therefore, the migraine model rat induced by postauricular injection of nitroglycerin may be a new model of cochlear migraine.

Abstract
Objective: The aim of this study was to evaluate efficacy and safety of 1470 nm diode laser enucleation of the prostate (DiLEP) and plasmakinetic resection of the prostate (PKRP) in elderly benign prostatic hyperplasia (BPH) patients with lower urinary tract symptoms. Methods: A total of 123 elderly patients with BPH were randomized to undergo either 1470 nm DiLEP or PKRP by means of a random number table from September 2020 to April 2022. The perioperative and postoperative data were studied during a 3- and 6-month follow-up. Results: The patients treated with 1470 nm DiLEP had significantly decreased operation time (74.6 ± 17.0 vs 98.8 ± 18.9 minutes, p < 0.001), hemoglobin loss (1.06 ± 0.49 vs 1.59 ± 0.60 g/dL, p < 0.001), bladder irrigation time (22.1 ± 8.1 vs 33.9 ± 10.0 hours, p < 0.001), catheter duration (3.2 ± 1.3 vs 5.8 ± 1.0 days, p < 0.001), and hospital stay (7.6 ± 1.4 vs 9.6 ± 1.3 days, p < 0.001) compared with the PKRP group. Besides, International Index of Erectile Function-5 score of 1470 nm DiLEP group at postoperative 3- and 6-month follow-up was significantly higher than PKRP group. No differences achieving statistical significance were identified in total prostate-specific antigen, maximum urinary flow rate, International Prostate Symptom Score, quality-of-life score, and the postvoid residual urine volume, transient incontinence, urethral stricture, bladder neck contracture, and retrograde ejaculation at 3- and 6-month follow-up. Conclusions: 1470 nm DiLEP is safer than PKRP, with a smaller effect on sexual function, and it is comparable with the efficacy of PKRP, thus making it more suitable for elderly BPH patients. Clinical Trial Registration number: S2021-463-01.

Abstract
Objective The present study aimed to explore the pathogenesis of the ascending sudden sensorineural hearing (SSNHL) loss by comparing the clinical characteristics and prognosis of acute low-frequency hearing loss (ALFHL) and ascending SSNHL. Methods A total of 43 patients with ALFHL and 122 patients with ascending SSNHL were enrolled in this study. First, the prognosis of patients with ALFHL and ascending SSNHL were compared, and the prognostic factors of AFHL and ascending SSNHL were analyzed. Results Acute low-frequency hearing loss and ascending SSNHL have no remarkable difference in complete recovery rate. Compared to ascending SSNHL, ALFHL has younger onset age, female prevalence, lower hearing threshold, shorter time from onset to recovery, and a lower proportion of combined tinnitus. The PTA at admission and delay from onset to therapy were significantly related to the prognosis of patients with ascending SSNHL, while only delay from onset to therapy was significantly related to the prognosis of patients with ALFHL. The majority of patients with ascending SSNHL and ALFHL recovered completely within 10 days from onset. Conclusion Audiogram shape plays a critical role in the prognosis of SSNHL. Ascending SSNHL and ALFHL may share a common pathological mechanism.

Abstract
The purpose of this study was to measure the vestibular function and plasma fibrinogen level in the nitroglycerin (NTG)-induced chronic migraine rats, and explore the effect of defibrinogenation on migraine and associated vestibular dysfunction. The chronic migraine rat model was built by recurrent NTG injection. Batroxobin was administrated as a defibrinogenating drug. We measured the mechanical withdrawal threshold, vestibular function, and fibrinogen level of the rats 30 min before and 2 h following the model establishment, as well as 1 h after batroxobin administration. The results showed that vestibular function was impaired in NTG-induced chronic migraine rats. The fibrinogen levels were increased following repeated NTG injections. However, defibrinogenation did not affect either aggravating or alleviating mechanical hyperalgesia or vestibular dysfunction in the migraine model rats. These findings suggest that the NTG-induced chronic migraine rat model can be used for research on migraine-associated vestibular symptoms. Albeit the association between elevated fibrinogen levels and migraine attacks can be observed, the role of excessive fibrinogen in the pathogenesis of chronic migraine is yet to be determined.

Abstract
BACKGROUND Identifying cellular and functional heterogeneity within aged prostate is critical for understanding the spatial distribution of prostate diseases. METHODS Aged human prostate peripheral zone (PZ) and transitional zone (TZ) tissues were used for single-cell RNA-sequencing. Results were validated by immunofluorescence staining. RESULTS We found that club/hillock epithelial cells, compared with other epithelial cells, had significantly higher NOTCH signaling activity and expressed higher levels of neuro-stems but lower androgen-related genes. These cells were primarily found in the TZ and provided a stem-like niche around the proximal prostate ducts. Significant heterogeneity was observed in the aged luminal population. A novel TFF3+ luminal subtype with elevated MYC and E2F pathway activities was observed, primarily in the PZ. Further analysis revealed that epithelial cells in the TZ had higher levels of stem- and inflammation-related pathway activities but lower androgen/lineage-related pathway activities than those in the PZ. Notably, the activation of MYC, E2F and DNA repair pathways significantly increased in PZ luminal cells. In the immune landscape, we found that the immune microenvironment in the TZ is more complex and disordered with more infiltration of NK and Treg cells. CD8 T cell and macrophage in the TZ exhibit both inflammation activation and suppression phenotypes. In the stroma, the TZ had a higher fibroblast density, and fibroblasts in the TZ exhibited stronger transcriptome activity in immunity and proliferation. Ligand-receptor interaction analysis revealed that fibroblasts could contribute to a NOTCH signaling niche for club/hillock cells in the TZ and balance the prostate immune microenvironment. The activation of stem properties, inflammatory infiltration and loss of androgen/lineage activity are prominent features distinguishing the TZ from PZ. CONCLUSIONS Our study explains the heterogeneity between the TZ and PZ of aged prostate, which may help understand the spatial distribution of prostate diseases and establish a foundation for novel target discovery.

Abstract
Subjective tinnitus patients experience more hearing difficulties than normal peers in complex hearing environments, even though most of these patients have normal pure-tone hearing thresholds. Using speech recognition tasks under different masking conditions can provide insight into whether the effects of tinnitus are lateralized and the mechanisms behind the effects. By simulating sound field recordings, we obtain a target speech sentence that can be perceived as presented on one side and noise or speech masking with or without spatial separation from it. Our study used the virtual sound field technique to investigate the difference in speech recognition ability between chronic subjective tinnitus patients and a normal-hearing control group under the four masking conditions (speech-spectrum noise masking or two-talker speech masking, with or without perceived spatial separation). Experiment 1 showed no differences for target speech perceived location (left or right), which rules out a lateralization of the effect of tinnitus patients. Experiment 2 further found that although tinnitus patients had weaker performance than normal people in very complex auditory scenarios, when the spatial cue of the target speech exists, they can make good use of this cue to make up for the original processing disadvantage and achieve a similar performance as the normal-hearing group. In addition, the current study distinguished the effects of informational masking and energetic masking on speech recognition in patients with tinnitus and normal hearing. The results suggest that the impact of tinnitus on speech recognition in patients is more likely to occur in the auditory center rather than the periphery.

Abstract
Bladder neck contracture (BNC) is a rare, late complication of transurethral resection of the prostate (TURP). Although the endoscopic procedure is the primary treatment for BNC, the recurrence rate remains high. Y-V plasty offers excellent surgical results for those individuals with refractory and recurrent BNC. Traditional open operations usually fail to provide satisfactory exposure to the operating field and lead to greater invasiveness. Interrupted sutures lead to prolonged operative time and increased anastomotic leakage. Laparoscopic modified Y-V plasty is performed through extraperitoneal access to the pelvis, which provides adequate exposure to the surgical view and avoids intra-abdominal injury. After incising the anterior bladder wall neck in a Y-shaped fashion, anastomosis is performed using two absorbable barbed sutures. The mucosa and submucosa layer of the bladder is closed to both sides with consecutive sutures in a V-shape before suturing serosa, and tunica muscularis are sutured to reinforce. The aforementioned procedures reduce leakage from the anastomosis and decrease operative time and patient trauma. Extraperitoneal laparoscopic modified Y-V plasty offers significant advantages over the open approach in terms of post-surgical recovery and invasiveness, making it a feasible and safe surgical option for patients with refractory BNC.

Abstract
The adrenal gland is a frequent site for metastasis, and the majority of the metastatic lesions of the adrenal gland normally originate from lung cancer, colon cancer, renal cell carcinoma, and melanoma. However, adrenal gland metastasis from breast invasive mucinous carcinoma is extremely rare. This report described a rare case of right adrenal gland metastasis in a 48-year-old female, who was diagnosed with breast invasive mucinous carcinoma and underwent right modified radical mastectomy with axillary lymph node dissection 5 years previously. A mass located on the right adrenal gland was detected during a routine examination 2 months ago. The patient was asymptomatic and adrenal gland MRI revealed a mass in the right adrenal gland. Definitive preoperative diagnosis failed to be established. Right adrenal gland laparoscopic adrenalectomy was performed and the diagnosis of adrenal gland metastasis of breast carcinoma was confirmed by pathological and immunohistochemical examination, especially ER, PR, GATA3, and HER-2. The patient remained in good condition by the time of writing.

Abstract
Objective To analyze the correlation between prognosis of sudden total deafness (STD) and peripheral blood inflammation markers including white blood cell count (WBC), monocytes, neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), fibrinogen (FIB). Methods 125 patients with STD who were hospitalized in our department from 2014 to 2019 were enrolled. The general physical conditions, clinical manifestations, pure tone audiometry, imaging examination, and peripheral blood inflammation markers were collected, and all patients were divided into effective and ineffective two groups according to the degree of hearing recovery at the time of discharge. Then binary logistic regression was used to analyze the correlation between multiple factors and prognosis, meanwhile the receiver operating characteristic (ROC) curve was used to evaluate the predictive value of the above prognostic factors. Results Compared with the ineffective group, patients in the effective group were younger and have higher PLR level and lower FIB levels. Age and PLR are independent prognostic factors. Taking age ≤ 56 years old, PLR >142.6 as the standard to predict the prognosis of patients with STD has the largest AUC with the potential effective rate reaching 78.1%. Conclusions Age and PLR are independent prognostic factors for patients with STD. The younger the age and the higher the PLR, the better the prognosis. Clinically, the prognosis of patients with STD can be evaluated by the patient's age and PLR level, which is of great significance to predict the prognosis of patients with STD.

Abstract
PURPOSE To investigate the risk factors for residual dizziness (RD) in patients with benign paroxysmal positional vertigo (BPPV) after successful repositioning. METHODS Searches were performed in PubMed, Embase, Cochrane library, Web of Science, Chinese National Knowledge Infrastructure, and Sino Med up to March 7, 2021 and references of relevant articles were screened. Data from eligible studies were meta-analyzed using Stata version 16.0 and Review Manager 5.4. RESULTS In this systematic review and meta-analysis of 4487 patients from 31 studies, the prevalence of RD was 43.0% (95% CI 39.0-48.0%). Age (MD 4.17; 95% CI 2.13-6.21, P = 0.000), female gender (OR = 1.28, 95% CI 1.11-1.47, P = 0.001), secondary BPPV (OR 1.88; 95% CI 1.27-2.77, P = 0.001), a longer duration of BPPV before treatment (MD 3.45; 95% CI 1.87-5.02, P = 0.000), abnormal ocular vestibular evoked myogenic potential (OVEMP, OR 4.34; 95% CI 2.78-6.78, P = 0.000), abnormal cervical vestibular evoked myogenic potential (CVEMP, OR 2.48; 95% CI 1.54-3.99, P = 0.000), higher Dizziness Handicap Index (DHI) score before treatment (MD 10.88; 95% CI 5.96-15.80, P = 0.000), anxiety (OR 9.58; 95% CI 6.32-14.52, P = 0.000), osteopenia (OR = 4.40, 95% CI 2.17-8.96, P = 0.000), onset in winter (OR 7.27; 95% CI 2.38-22.24, P = 0.001) and with a history of BPPV (OR 1.79; 95% CI 1.06-3.04, P = 0.03) are the risk factors for RD in patients with BPPV after successful repositioning. The affected side, location or type of semicircular involvement, hyperlipidemia, diabetes, hypertension, heart disease, migraine, sleep disorders, canalolithiasis/cupulolithiasis, the number of times the canalith repositioning procedures (CRPs) were performed and number of vertigo attacks did not correlate with the occurrence of RD. CONCLUSIONS Despite successful treatment, nearly half of the BPPV patients developed RD. RD seems to be a syndrome caused by multiple factors. The pathogenesis of most factors can be explained by psychological and/or physical disorders. Early recognition of these risk factors contributes to the prevention and treatment of RD.

Abstract
This study aimed to screen and verify the important prognostic genes related to clear cell renal cell carcinoma (ccRCC) and further analyze their relationship with the immune microenvironment. Gene expression profiles from the TCGA-KIRC, GSE46699, GSE36895, and GSE16449 datasets were utilized to explore differentially co-expressed genes in ccRCC. We screened 124 differentially co-expressed genes using a weighted gene co-expression network and differential gene expression analyses. Univariate and multivariate Cox survival analyses revealed that the expressions of genes CGN, FECH, UCHL1, and WT1 were independently related to the overall survival of ccRCC patients. Kaplan–Meier survival analysis was performed, and CGN was found to have the strongest correlation with the prognosis of ccRCC patients and was consequently selected for further analyses and experimental verification. The results showed that NK cell activation, resting dendritic cells, resting monocytes, and resting mast cells were positively correlated with CGN expression; CD4+ memory activated T cells, regulatory T cells, and M0 macrophages were negatively correlated with CGN expression. Finally, using western blotting and reverse transcription polymerase chain reaction, we verified that the CGN protein level was down-regulated in ccRCC samples, which was consistent with the mRNA levels. CGN was thus identified as diagnosis and prognosis biomarker for ccRCC and is related to the immune microenvironment.

Abstract
To explore whether patients with unilateral idiopathic sudden sensorineural hearing loss (uISSNHL) have normal speech in noise (SIN) perception under different masking conditions after complete recovery of pure tone audiometry. Eight completely recovered uISSNHL patients were enrolled in ISSNHL group, while 8 normal-hearing adults matched with age, gender, and education experience were selected as the control group. Each group was tested SIN under four masking conditions, including noise and speech maskings with and without spatial separation cues. For both ISSNHL and control groups a two-way ANOVA showed a statistically significant effect of masking type (p = 0.007 vs p = 0.012). A significant effect of perceived spatial separation (p < 0.001 vs p < 0.001). A significant interaction between masking type and perceived spatial separation was found (p < 0.001 vs p < 0.001). A paired sample T-test showed that the SIN perception of the control group was statistically significant lower than that of ISSNHL patients only under speech masking without spatial separation cues (p = 0.011). There were still abnormalities in the auditory center shortly after complete recovery in the ISSNHL group (within 2 weeks). However, the auditory periphery and higher-level ability to use spatial cues was normal.

Abstract
Introduction Measurement of intra-cavernous pressure (ICP) is an internationally recognized method to evaluate erectile function of animals, however, this process is invasive, destructive, and cannot be repeated, leading to a daunting challenge for monitoring the changes in erectile function throughout the whole treatment duration. Aim To verify whether infrared ray thermography technology based system could be a good substitution of ICP for evaluating rat erectile function. Methods A novel thermal image-based method, infrared ray thermography technology (IRT) was employed to monitor erectile function in erectile dysfunction (ED) rats. To detect the sensitivity and specificity of this new technology, 4 ED rat models (Diabetic, nerve-injury, vascular-injury and aged ED models) were established and subjected to both ICP and IRT test. Outcomes Statistical comparisons were done to test the effectiveness of this new way for detecting and dynamically monitoring erectile function. Results Based on the data curves obtained from ICP and IRT, the IRT showed a similar trend (including peak value, climbing speed) as that of ICP. IRT is considered as a precise way to monitor the real-time changes of erectile function in all ED rat models. The AUC of peak temperature detected by IRT in DMED, aged ED, vascular-injury ED, the nerve-injury ED and total ED rat models were 0.9811,0.9836,0.9893,0.9989 and 0.9882, respectively. Meanwhile, the AUC of temperature climbing rate were 0.6486,0.8357,0.9184,0.8675and 0.8168.Also,it is a non-invasive process of dynamically monitoring erectile function of a same rat at different time points (before and after drug intervention). The data showed that the real-time recovery by tadalafil was obtained by IRT methods even after treatment for only 2 weeks in the diabetic ED (DMED) rat model. Conclusion A novel noninvasive method for monitoring erectile function in rat ED models was established, and can replace or supplement ICP test. Liu S, Zhao Z, Wang Z et al.

Abstract
Objective: The relation between cognition and hearing loss has been increasingly paid high attention, however, few studies have focused on the role of high-frequency hearing loss in cognitive decline. This study is oriented to role of hearing loss especially high-frequency hearing loss in cognitive impairment among elderly people (age ≥ 60 years). Methods: The Montreal Cognitive Assessment Scale (MoCA) and pure tone audiometry were used to investigate the hearing loss and cognitive function of 201 elderly people older than 60 years. Factors possibly related to cognitive impairment including age, years of education, occupation, living conditions, history of otologic diseases, and high blood pressure were registered. This study consisted of two parts. First, univariate analysis and multiple linear regressions were performed to analyze the possible influencing factors of cognitive function among the 201 elderly people. Second, average hearing thresholds of low frequencies (250, 500 Hz), intermediate frequencies (1 k, 2 kHz), and high frequencies (4 k, 8 kHz) were calculated to screen out 40 cases with high-frequency hearing loss alone and 18 cases with normal hearing. Univariate analysis was used to compare the general condition, cognitive function, and each cognitive domain between the two groups, analyzing the relation between high-frequency hearing loss and cognitive function. Result: We found that age, years of education, pure tone average (PTA), occupation, living condition, history of otologic diseases, years of self-reported hearing loss, and hypertension history were related to cognitive function. Furthermore, age, education experience, duration of self-reported hearing loss, and hypertension were independent factors (p < 0.05). PTA was negatively related with attention, orientation, and general cognition (p < 0.05). There were only 18 cases (9.0%) with normal hearing, and 40 cases (19.9%) with abnormal high-frequency hearing alone. The overall cognitive function showed no significant difference between them (p > 0.05); in contrast, the speech and abstract ability were significantly decreased in cases with high-frequency hearing loss (p < 0.05). Conclusion: The increase of PTA among the elderly may affect the overall cognition by reducing attention and orientation. High-frequency hearing loss alone can affect the language and abstract ability to a certain extent, which is worthy of more attention.

Abstract
Objective:To explore the distribution of pathogenic bacteria and drug sensitivity among patients with chronic suppurative otitis media. Methods:Patients with chronic suppurative otitis media who were hospitalized in the Department of Otolaryngology, People's Hospital, Peking University for surgery from January 1, 2019 to May 1, 2021 were enrolled as the subjects, then take the deep secretions of the external auditory canal for bacterial culture. Finally, the distribution and drug sensitivity of the pathogenic bacteria are analyzed. Results:A total of 126 patients were enrolled, of which 53 were culture-positive, and 57 strains of bacteria were isolated, including 47 strains of Gram-positive cocci, 10 strains of Gram-negative bacilli. Among Gram-positive cocci, 24 methicillin-sensitive staphylococcus aureus(MSSA) strains, 7 methicillin-resistant staphylococcus aureus(MRSA) strains, 14 coagulase-negative staphylococcus strains, 1 strain enterococcus faecium, and 1 strain otitis Zurich. 4 strains(4/10) of pseudomonas aeruginosa among Gram-negative bacilli. Among them, MSSA has a high resistance rate to levofloxacin, moxifloxacin, clindamycin, and gentamicin, and high sensitivity to oxacillin, vancomycin, linezolid, and rifampin. MRSA is highly resistant to common antibiotics except vancomycin, rifampicin, and linezolid. The Gram-negative bacilli have higher resistance rates to levofloxacin, aztreonam, ciprofloxacin, ceftazidime, and piperacillin/tazobactam, and to meropenem, imipenem, amika star, cefepoxime, cefoperazone/sulbactam, and tobramycin are more sensitive. The results of univariable and multivariable analysis showed that age and bacterial infection were independent factors related to dry ears, and the duration of the disease history was a non-independent factor. Conclusion:The main pathogenic bacteria infections in patients with chronic suppurative otitis media are MSSA, MRSA, and pseudomonas aeruginosa. Whether it is combined with bacterial infection and age are independent factors related to whether patients with chronic suppurative otitis media could have dry ears. Therefore, patients with chronic suppurative otitis media should be treated with specific antibiotics or surgical interventions as soon as possible in combination with drug sensitivity results to avoid prolonging disease course or causing serious infectious complications.

Abstract
OBJECTIVE To analyze the factors affecting the long-term prognosis of tinnitus accompanied by unilateral idiopathic sudden sensorineural hearing loss (SSNHL). METHODS A total of 161 patients with sudden hearing loss (HL) accompanied by tinnitus were enrolled. All patients had two separate telephone follow-ups and were asked about changes in tinnitus. The severity of tinnitus at admission and the outcome at discharge were assessed in terms of the patients' sex, age, level of HL, type of audiogram, etc. Results: The prognosis of tinnitus after SSNHL had no relationship with grades of HL or hearing recovery. Initial tinnitus level was remarkably associated with tinnitus improvement at discharge and was an independent risk factor for the long-term prognosis of residual tinnitus after SSNHL (odds ratio 0.722, 95% confidence interval 0.550-0.949, p = 0.019), and the median recovery time was 23.00 ± 3.80 months. CONCLUSIONS Residual tinnitus after SSNHL has a tendency of self-recovery. The short-term prognosis of tinnitus may be related to psychological changes caused by hearing recovery, while the long-term prognosis of residual tinnitus after SSNHL is related only to the initial tinnitus level, with a median recovery time of approximately 2 years.

Abstract
BACKGROUND Migraine is more common in Meniere's disease patients, who have some certain anatomical variations. But there are limited studies focusing on the anatomical variations in patients with Meniere's disease and migraine. OBJECTIVE To explore the clinical and anatomical features in Meniere's disease patients with and without migraine, determining whether the coexistence of migraine can be used as a basis for clinical subtyping of Meniere's disease. METHODS Ninety-five Meniere's disease patients and ninety-five healthy subjects matched with age, sex were selected. A detailed questionnaire based on the diagnosis criteria of Meniere's disease and migraine was designed. According to the CT scan, we divided the mastoid cell system of all the subjects into two types: well-pneumatization type and poor-pneumatization type. Meanwhile, the shortest distance between the sigmoid sinus and the posterior wall of the external acoustic canal was measured. RESULTS Compared with those without migraine, Meniere's disease patients with migraine had a higher female comorbidity, poorer mastoid pneumatization, shorter distance between the sigmoid sinus and posterior wall of the external acoustic canal, longer history, higher frequency of vertigo attacks and better average hearing threshold. CONCLUSIONS In our study, anatomical features as well as several clinical manifestations were proved to differ significantly between Meniere's disease patients with and without migraine, indicating the coexistence of migraine may be one standard for the clinical subtyping of Meniere's disease.

Abstract
Lymph node metastasis (LNM) is an important prognostic factor for bladder cancer (BCA) and determines the treatment strategy. This study aimed to determine related clinicopathological factors of LNM and analyze the prognosis of BCA. A total of 10,653 eligible patients with BCA were randomly divided into training or verification sets using the 2004-2015 data of the Surveillance, Epidemiology, and End Results database. To identify prognostic factors for the overall survival of BCA, we utilized the Cox proportional hazard model. Independent risk factors for LNM were evaluated via logistic regression analysis. T-stage, tumor grade, patient age and tumor size were identified as independent risk factors for LNM and were used to develop the LNM nomogram. The Kaplan-Meier method and competitive risk analyses were applied to establish the influence of lymph node status on BCA prognosis. The accuracy of LNM nomogram was evaluated in the training and verification sets. The areas under the receiver operating characteristic curve (AUC) showed an effective predictive accuracy of the nomogram in both the training (AUC: 0.690) and verification (AUC: 0.704) sets. In addition, the calibration curve indicated good consistency between the prediction of deviation correction and the ideal reference line. The decision curve analysis showed that the nomogram had a high clinical application value. In conclusion, our nomogram displayed high accuracy and reliability in predicting LNM. This could assist the selection of the optimal treatment for patients.

Abstract
OBJECTIVE To validate a prognostic nomogram (Xylinas' nomogram) for intravesical recurrence after radical nephroureterectomy for primary upper urinary tract urothelial carcinoma patients of Asian descent. METHODS Clinicopathological and survival data from 243 primary urinary tract urothelial carcinoma patients who underwent radical nephroureterectomy with bladder cuff excision between January 2004 and May 2017 were collated. Univariate and multivariable Cox regression analyses were performed to identify independent risk factors associated with intravesical recurrence-free survival. External validation was determined using regression coefficients abstracted from previously published data. Performance was then quantified through calibration and discrimination, according to concordance indexes (c-index) in receiver operating characteristic curves. RESULTS 163 patients met our eligibility criteria and were finally included in this study. At a median follow-up of 60 months, intravesical recurrence occurred in 29.4% (n = 48). Multivariable analysis revealed that being male, ureteral tumor location, tumor multifocality and previous bladder cancer were independent prognostic factors of intravesical recurrence-free survival. When Xylinas' nomogram was applied to our cohort, the discriminatory power was found to be roughly equivalent with a c-index of 68.3% for the reduced model and 68.4% for the full model. Calibration plots also revealed intravesical recurrence predictions at 3, 6, 12, 18, 24 and 36 months had relative concordance. Contrasting the respective performances of the reduced and full model suggests there is no significant difference between the two (all P > 0.05). CONCLUSIONS This nomogram appears accurate at predicting intravesical recurrence after radical nephroureterectomy for primary urinary tract urothelial carcinoma in Asian populations. However, it remains necessary to data mine for unknown prognostic factors for optimization. Further external validation is required across larger, ethically diverse populations before applying this nomogram in clinical practice.

Abstract
The dysregulation of caspase 4 (CASP4) expression is related to the occurrence, development, and outcome of many malignant tumors; however, its role in clear cell renal cell carcinoma (ccRCC) remains unclear. Herein, we investigated the expression of CASP4 in tumor tissues and its relationship with clinical prognosis, immune infiltration, and drug sensitivity status of ccRCC patients. Oncomine and The Cancer Genome Atlas (TCGA) databases were used to determine CASP4 mRNA expression in ccRCC patients. The correlation between CASP4 expression and disease prognosis was evaluated using Kaplan–Meier analysis. Related pathways were obtained from TCGA database via gene set enrichment analysis (GSEA) and gene set variation analysis (GSVA). Meanwhile, genes co-expressing with CASP4 in ccRCC were investigated. Finally, we analyzed the proportion of tumor-infiltrating immune cells (TICs) using the CIBERSORT computational method and assessed CASP4 methylation and its relationship with drug sensitivity. Immunohistochemical analysis of 30 paired ccRCC and adjacent normal tissues confirmed the in silico results. CASP4 mRNA expression in ccRCC was significantly higher than that in the normal tissues, positively correlated with clinicopathological features (clinical stage and pathological grade), and negatively correlated with patient overall survival (OS). GSEA and GSVA showed that the genes in the CASP4-high expression group were primarily enriched in immune-related activities. Moreover, CIBERSORT analysis of TIC proportions revealed that activated CD4 memory T cells were positively correlated with CASP4 expression. Notably, methylation analysis revealed that the abnormal upregulation of CASP4 might be caused by hypomethylation. Finally, we found that the abnormal expression of CASP4 may be related to tumor drug resistance. Overall, our study shows that CASP4 is overexpressed in ccRCC and is an important factor affecting disease prognosis. Hence, CASP4 may serve as a potential prognostic biomarker and therapeutic target in ccRCC.

Abstract
Background The curative effect of sacral neuromodulation (SNM), used to treat overactive bladder (OAB) patients, is definite. However, some patients still have recurrent symptoms after SNM and unsatisfactory symptom improvement after repeated adjustments of the stimulation parameters combined with oral drugs. These are referred to as black-zone OAB patients. The described SNM is the standard method, which involves a constant-frequency stimulation (CFS) of the patient's specific sacral nerve. A new treatment strategy, which combines the advantages of high-frequency and low-frequency stimulations to generate variable-frequency stimulation (VFS), has not yet undergone a formal randomized clinical trial. Therefore, we designed this clinical trial to evaluate the efficacy and safety of VFS-SNM and CFS-SNM in the treatment of black-zone OAB patients. Methods We designed a multicenter, prospective, randomized, blinded, self-controlled trial with a 12-week follow-up period. The trial randomly divides the enrolled patients into CFS-SNM and VFS-SNM groups. The main evaluation index is the comparative effectiveness of VFS-SNM and CFS-SNM at the last follow-up. The secondary evaluation indices include the change in the OAB symptom score, the quality of life (QOL) score, and the visual analog scale compared with the baseline period at each follow-up time point. Discussion Previous studies and our pre-experimental results suggest that black-zone OAB patients may benefit from VFS-SNM. Twelve weeks of VFS-SNM are effective in 40%, and the non-inferior cutoff value is 10% (80% power, 0.05 significance level, 20% loss to follow up). Thus, the calculated sample size is 37 cases each for CFS and VFS groups. The trial is expected to be carried out in 18 centers, but centers will be added or removed as appropriate depending on specific implementation conditions. Clinical researchers at each center will be responsible for screening qualified participants. This is the first randomized controlled trial to comprehensively evaluate the efficacy and safety of VFS-SNM in black-zone OAB patients, which will provide high-quality clinical evidence and may provide new clinical options for such patients.

Abstract
Overactive bladder (OAB) is a common urological disease, reducing patient quality of life (QoL). Sacral neuromodulation (SNM) is a treatment option used when conservative treatment is inadequate. However, constant frequency stimulation-SNM (CFS-SNM) may not be sufficiently effective in achieving targeted symptom reduction in some patients. For such black-zone patients, a different treatment strategy is needed. Variable frequency stimulation (VFS) has been used for deep-brain stimulation treatment in patients with Parkinson’s disease with positive outcomes. Accordingly, in this study, we hypothesized the promising outcomes of VFS-SNM in black-zone OAB patients. Here, we evaluated the efficacy and safety of VFS-SNM viz-a-viz CFS-SNM in a black-zone patient with refractory OAB whose frequent micturition symptoms were not relieved after undergoing traditional conservative treatment. A 50-year-old male patient was treated with CFS-SNM at our hospital in October 2016, but his symptoms recurred after administering multiple medications and program-controlled parameter adjustments. We then treated the patient with VFS-SNM in March 2020. A 2-week follow-up through telephonic interviews was conducted; the improvements in voiding symptoms were evaluated by calculating the OAB symptom score (OABSS) and OAB-related QoL (OAB-QoL) score. We observed that OABSS was significantly lower after VFS-SNM than after CFS-SNM. Further, we observed that VFS-SNM significantly improved daytime and nocturnal micturition frequency, as evident from the reduced OABSSs from after CFS-SNM to after VFS-SNM. The main reason for patient dissatisfaction after CFS-SNM was the increased average daily micturition frequency and urgency. VFS-SNM controlled the micturition frequency to within the patient’s acceptable range, significantly improving the patient’s QoL (40% improvement in OAB-QoL score). To the best of our knowledge, this is the first case report on the use of VFS-SNM with positive outcomes in a black-zone OAB patient, suggesting that VFS-SNM is not inferior to CFS-SNM in the treatment of black-zone patients.

Abstract
The purpose of this study was to identify key autophagy-related genes (ARGs) in patients with renal cancer (RC) by bioinformatics analysis, and to clarify their potential prognostic value. Thirty-eight differentially expressed ARGs were identified between RC and normal tissues based on The Cancer Genome Atlas database. Functional enrichment analysis suggested that autophagy may play a tumor-promoting role in the initiation of RC. We established a prognostic model with two ARGs (CASP4 and BIRC5) demonstrating significant correlations in expression levels with patient overall survival (OS). Multivariate Cox regression analysis showed that age and the autophagy genes prognostic model were independent prognostic factors for patients with RC. Considering the known prognostic significance of clinical stage in RC, we constructed a nomogram based on age, clinical stage, and the prognostic model. The prognostic model was verified in a separate validation set and external cohort of patients from Beijing Hospital. Patients of low and high risk were defined based on the median risk value calculated by the model and the high risk appeared associated with a significant shorter OS (P < 0.01). Overall, our findings reveal that ARGs have potential prognostic value in patients with RC, providing new directions for targeted therapy.

Abstract
Bladder cancer (BLCA) is a common malignancy arising from the urinary bladder and therapeutic options are limited. However, the mechanisms underlying BLCA development are poorly understood. In this study, robust rank aggregation was used to integrate five GEO BLCA microarray datasets for identifying differentially expressed genes (DEGs) between non-muscular invasive BLCA and muscular invasive BLCA. One-hundred fifty-four DEGs related to the degree of BLCA infiltration, including 24 immune-related genes (IRGs), were identified. Missense mutations were the most common type in IRGs. Ten hub IRGs were identified by protein-protein interaction network analysis. Gene set enrichment analysis and gene set variation analysis of two novel BLCA-related genes (TYROBP and FCER1G) revealed that they were related to immunity. Nine survival-related IRGs were identified, and their potential regulation by transcription factors was analyzed. An immune-related gene-based prognostic index (IRGPI) comprising CTSE, CXCL10, FAM3B, MMP9, OLR1, and S100P was constructed using multivariate analysis. The reliability of the IRGPI was evaluated using independent datasets, and correlations between the IRGPI and clinicopathological characteristics, as well as the immune microenvironment, were evaluated. Finally, a nomogram was established to evaluate the prognosis of patients with BLCA. Our data provide new insights into the pathogenesis of BLCA and target genes for immunotherapy. The application of molecular markers for hierarchical prediction paves the way for precision medicine.

Abstract
BACKGROUND The risk of positive lymph nodes in patients with muscle-invasive bladder urothelial carcinoma (MIBC) can be used to guide treatment recommendations. However, little is known about the effect of age on lymph node positivity (LN+). This study aimed to evaluate the effect of age on LN+ in MIBC. METHODS We analyzed patients with stage T2-T4 bladder urothelial carcinoma who had not received preoperative radiotherapy, had at least one lymph node examined, and underwent cystectomy between 1998 and 2015. The Cochran-Armitage trend test and logistic univariate and multivariate analyses were used to evaluate the effect of age on LN+ in all T stages. RESULTS In total, 15,624 patients with MIBC were identified, including 747 patients aged ≤50 years (4.78%), 2614 patients aged 50-59 years (16.73%), 4914 patients aged 60-69 years (31.45%), 5225 patients aged 70-79 years old (33.44%), and 2124 patients aged > 80 years (13.59%). In T2-T4 staging, LN+ was negatively correlated with age. After adjustment for several covariates, multivariate logistic regression analysis revealed that age was an independent risk factor for LN+. CONCLUSIONS In this large SEER analysis, Young patients with MIBC have a higher risk of lymph node metastasis. This finding is worthy of further study and may eventually affect the treatment decisions of young patients.

Abstract
OBJECTIVES To develop an evidence base to guide clinicians treating adults with large proximal ureteral stones (LPUS) greater than 10 mm. METHODS A systematic search of PubMed, EMBASE, and Cochrane Library was conducted to identify randomized controlled trials (RCT) concerning different LPUS management techniques including laparoscopic ureterolithotomy (LU), percutaneous nephrolithotomy (PCNL) and ureteroscopic lithotripsy (URL) up until March 2020. We followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement when searching and determining inclusion. All included articles were quality assessed and the data analyses were conducted with Review Manager (5.3). RESULTS 12 RCTs involving 1416 patients met our eligibility criteria and were analyzed. Of these participants, 44.6% (n = 632) underwent URL, 25.5% (n = 361) PCNL, and 29.9% (n = 423) LU. Pooled analysis revealed that URL had a significantly lower stone-free rate (SFR) compared to PCNL and LU (both with p < 0.05). URL had a significantly higher ureteral injury rate compared to LU (Relative risk (RR) = 5.27, 95% confidence interval (CI) 1.52 to 18.22, p = 0.009) and PCNL (RR = 4.11, 95% CI 1.03 to 16.34, p = 0.04). However, no significant differences were found between PCNL and LU in terms of SFR or overall complications, both with p > 0.05. URL initially costs less than PCNL (Weighted mean difference (WMD) -597.35US$, 95% CI -823.10 to -371.60, p < 0.00001), but being less effective creates greater demand for repeat or ancillary treatments compared to LU (RR 15.65, 95% CI 2.11-116.12, p = 0.007) and PCNL (RR 8.86; 95% CI 3.19-24.60; p < 0.00001). CONCLUSIONS Both PCNL and LU appear more effective and safer than URL for LPUS; although, LU has higher risk of urine leakage and is more likely incur trauma which requires additional support. However, caution must be taken because this recommendation is based upon a very limited number of clinical studies, and even fewer comparing flexible ureteroscopic technologies. Further prospective real-world studies or RCTs comparing flexible URL, LU and PCNL are required, as well as an in depth analysis of the hidden costs involved in unsuccessful URL treatments.

Abstract
BACKGROUND Stress urinary incontinence (SUI) is a common, distressing health issue which affects many women. Mid-urethral sling (MUS) surgeries are recommended as gold standard interventions, although evidence regarding their impact on female sexual function remains controversial. AIM To provide high-quality evidence of the impact of MUS surgeries on sexual functions in women with SUI. METHODS A systematic search of PubMed, Embase, and the Cochrane Library was conducted to identify studies assessing the effect of MUS treatments on sexual functions in women with SUI. The included studies were prospective randomized or non-randomized trials which assessed patients using 2 validated questionnaires, the Female Sexual Function Index (FSFI) and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Pre- and postoperative data regarding sexual function were extracted. Meta-analysis of comparable data was performed using Review Manager (version 5.3) software. MAIN OUTCOME MEASURES The relationship between MUS interventions and sexual functions was analyzed by pooling weighted mean differences (WMD) with 95% CI from studies which used either the FSFI or PISQ-12 questionnaires, before and after receiving surgical interventions. RESULTS Of the 22 eligible studies, 13 utilized FSFI and 9 adopted the PISQ-12. Pooled analysis indicates that 6-month postoperative PISQ-12 scores were significantly higher than preoperative scores (WMD -3.31 points; 95% CI -5.32 to -1.30; P = .001). Similar results were found at the 12-month juncture (WMD -3.30 points; 95% CI -6.01 to -0.58; P = .02) and at 24 months (WMD -4.44 points; 95% CI -5.45 to -3.44; P < .00001). Likewise, pooled postoperative FSFI total scores were significantly higher than preoperative scores at 6 months (WMD -2.22 points; 95% CI -3.36 to -1.08; P = .00001) and 12 months (WMD -3.49 points; 95% CI -5.96 to -1.02; P = .006). Postoperative FSFI sub-scores also suggest that desire, arousal, orgasm, lubrication, satisfaction, and pain during sexual intercourse significantly improved postoperatively (all P < .05). Moreover, combined evidence highlighted a significant reduction in coital incontinence postoperatively (risk ratio 5.78; 95% CI 3.16-10.58; P < .00001). CLINICAL IMPLICATIONS These assessment tools might be more appropriately used to create opportunities for counseling. STRENGTHS & LIMITATIONS We encountered substantial heterogeneity and insufficient long term follow-up data. There is also a distinct lack of standards, in terms of data recording and reporting across this evidence base which adds to the problems with the PISQ-12 and FSFI which, even though validated, appear unsophisticated and not necessarily fit-for-purpose. CONCLUSION This meta-analysis confirms that sexual functions do improve after MUS surgeries for women with SUI. Lai S, Diao T, Zhang W, et al.

Abstract
BACKGROUND Bladder cancer (BCA) is the most common urinary tumor, but its pathogenesis is unclear, and the associated treatment strategy has rarely been updated. In recent years, a deeper understanding of tumor epigenetics has been gained, providing new opportunities for cancer detection and treatment. METHODS We identified prognostic methylation sites based on DNA methylation profiles of BCA in the TCGA database and constructed a specific prognostic subgroup. RESULTS Based on the consistent clustering of 402 CpGs, we identified seven subgroups that had a significant association with survival. The difference in DNA methylation levels was related to T stage, N stage, M stage, grade, sex, age, stage and prognosis. Finally, the prediction model was constructed using a Cox regression model and verified using the test dataset; the prognosis was consistent with that of the training set. CONCLUSIONS The classification based on DNA methylation is closely related to the clinicopathological characteristics of BCA and determines the prognostic value of each epigenetic subtype. Therefore, our findings provide a basis for the development of DNA methylation subtype-specific therapeutic strategies for human bladder cancer.

Abstract
Background Abiraterone and MDV3100 are two effective anticancer agents for prostate cancer, however, the mechanism of their downstream action remains undefined. Methods A dual fluorescent biosensor plasmid was transfected in LNCaP cells to measure mitophagy. The DNA of LNCaP cells was extracted and performed with quantitative real-time PCR to detect mitochondrial DNA copy number. JC-1 staining was utilized to detect the mitochondrial membrane potential and electron microscope was performed to analyze mitochondrial morphology. Moreover, the protein levels of mitochondrial markers and apoptotic markers were detected by western blot. At last, the proliferation and apoptosis of LNCaP cells were analyzed with CCK-8 assay and flow cytometry after abiraterone or MDV3100 treatment. Results Mitophagy was induced by abiraterone and MDV3100 in LNCaP cells. The low expression level of mitochondrial DNA copy number and mitochondrial depolarization were further identified in the abiraterone or MDV3100 treatment groups compared with the control group. Besides, severe mitochondria swelling and substantial autophagy-lysosomes were observed in abiraterone- and MDV3100-treated LNCaP cells. The expression of mitochondria-related proteins, frataxin, ACO2 and Tom20 were significantly downregulated in abiraterone and MDV3100 treated LNCaP cells, whereas the expression level of inner membrane protein of mitochondria (Tim23) was significantly upregulated in the same condition. Moreover, the proliferation of LNCaP cells were drastically inhibited, and the apoptosis of LNCaP cells was increased in abiraterone or MDV3100 treatment groups. Meanwhile, the addition of mitophagy inhibitor Mdivi-1 (mitochondrial division inhibitor 1) could conversely elevate proliferation and constrain apoptosis of LNCaP cells. Conclusions Our results prove that both abiraterone and MDV3100 inhibit the proliferation, promote the apoptosis of prostate cancer cells through regulating mitophagy. The promotion of mitophagy might enhance the efficacy of abiraterone and MDV3100, which could be a potential strategy to improve chemotherapy with these two reagents.

Abstract
OBJECTIVE To assess the efficacy and safety of green-light laser photoselective vaporisation of the prostate (PVP) compared with transurethral resection of the prostate (TURP) for lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). DESIGN Systematic review and meta-analysis, conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. DATA SOURCES PubMed, EMBASE, the Cochrane Library until October 2018. ELIGIBILITY CRITERIA Randomised controlled trials and prospective studies comparing the safety and efficacy of PVP versus TURP for LUTS manifesting through BPH. DATA EXTRACTION AND SYNTHESIS Perioperative parameters, complications rates and functional outcomes including treatment-related adverse events such as International Prostate Symptom Score (IPSS), maximum flow rate (Qmax), postvoid residual (PVR), quality of life (QoL) and International Index of Erectile Function (IIEF). RESULTS 22 publications consisting of 2665 patients were analysed. Pooled analysis revealed PVP is associated with reduced blood loss, transfusion, clot retention, TUR syndrome, capsular perforation, catheterisation time and hospitalisation, but also with a higher reintervention rate and longer intervention duration (all p<0.05). No significant difference in IPSS, Qmax, QoL, PVR or IIEF at 3, 24, 36 or 60 months was identified. There was a significant difference in QoL at 6 months (MD=-0.08; 95% CI -0.13 to -0.02; p=0.007), and IPSS (MD = -0.10; 95% CI -0.15 to -0.05; p<0.0001) and Qmax (MD=0.62; 95% CI 0.06 to 1.19; p=0.03) at 12 months, although these differences were not clinically relevant. CONCLUSION PVP is an effective alternative, holding additional safety benefits. PVP has equivalent long-term IPSS, Qmax, QoL, PVR, IIEF efficacy and fewer complications. The main drawbacks are dysuria and reintervention, although both can be managed with non-invasive techniques. The additional shortcoming is that PVP does not acquire histological tissue examination which removes an opportunity to identify prostate cancer.

Abstract
Background: Prostate cancer is the second leading cause of cancer-related deaths in Western countries. Most patients diagnosed with advanced prostate cancer can be treated with the main treatment: androgen deprivation therapy (ADT). The androgen receptor (AR) signaling axis plays a pivotal role in the progression of prostate cancer. However, most patients can ultimately progress to the castration-resistant prostate cancer (CRPC) stage within 2 years. At this stage, drugs targeting the AR signaling axis, including enzalutamide and abiraterone acetate, cannot prevent the progression of prostate cancer, thus predicting a poor prognosis. The molecular mechanism lies in the aberrant AR reactivation, which exhibits an adaptive response to ADT, such as the presence of AR splice variants. Thus, CRPC treatment remains a challenge. Purpose: In addition to the AR axis, a mechanism leading to this progression should be determined. The present study mainly compared palmitoylated proteins between androgen-treated LNCaP cells and non-treated LNCaP cells by palmitoylome profiling, to illustrate the changes at proteomic levels. Materials and methods: To screen the androgen-induced palmitoylated proteins, we conducted proteomic experiments using clickable palmitate probe (Alk-C16) between three individual pairs of androgen-treated and non-treated LNCaP cells. Results: We identified 4351 unique peptides corresponding to 835 proteins, among them a number of these identified proteins were palmitoylated proteins, particularly eIF3L. Androgen treatment significantly increased the palmitoylation level of eIF3L, an individual subunit of eIF3. As an initiation factor, eIF3L plays a pivotal role in the translation of mRNAs encoding growth-promoting proteins by enhancing translation rates, thus controlling cell proliferation. Conclusion: In this study, we demonstrated that the regulation of eIF3L palmitoylation may provide new directions for the therapy of prostate cancer. Moreover, the increased level of androgen-induced eIF3L may be used as a biomarker for the diagnosis of early-stage prostate cancer.

Abstract
RATIONALE Simple renal cyst (SRC) is a benign disease. However, rarely renal cell carcinoma (RCC) may be raised at the wall of a preexisting SRC. We herein describe 2 unusual cases of RCC arising from the outer surface of the free wall of the renal cyst. PATIENT CONCERNS A 75-year-old female and a male were admitted to our department because of an asymptomatic renal cystic mass. Although the case history, preoperative imaging, and intraoperative examination of the cyst were carefully evaluated, no concerns were raised with respect to the underlying malignancy. DIAGNOSIS RCC of the clear cell type was diagnosed based on the histology and pathological examination. INTERVENTIONS With an initial diagnosis of SRC, the retroperitoneal laparoscopic de-roofing of the SRC was performed in both of the patients. When the diagnoses were confirmed 7 days postoperative, both of them were readmitted to our department for a radical nephroureterectomy. OUTCOMES The postoperative course was uneventful and the two patients did not undergo further chemotherapy. They are currently well and have no clinical or radiological signs of recurrence. LESSONS Such cases remind us that seemingly benign renal cysts may harbor underlying neoplasia. Further evaluation and periodical follow-up are also recommended on the management of those seemingly benign renal cysts.

Abstract
To assess the clinical effect of miniaturized percutaneous nephrolithotomy (MPCNL) and flexible ureteroscopy lithotripsy (FURL) for the treatment of renal and proximal ureteral calculi of ≤2 cm.A retrospective analysis was carried out on clinical data of 106 patients with kidney or upper urethral calculi. Among these patients, 58 underwent the MPCNL, and 48 received FURL. Stone-free rates, operating time, blood loss, hemoglobin drop, length of hospital stay, complications, and renal damage indexes were compared.The stone removal rates of the FURL and MPCNL groups were 81.25% versus 87.93% (p > .05). Although operating time was significantly shorter in the MPCNL group, hospital stays were significantly shorter in the FURL group. In addition, pooled analysis showed that mean estimated blood loss was significantly higher in the PCNL group but the hemoglobin decline of the FURL group and PCNL group had no significant difference. The PCNL group had no significant difference in complications compared to the FURL group. Differences on the creatinine levels and urea nitrogen levels before the operation and after the operation were not statistically significant.FURL is an effective method for treating renal stone. FURL not only had a similar stone-free rate as compared to MPCNL but also was associated with less blood loss and more favorable recovery time. However, FURL had a longer operative time.

Abstract
OBJECTIVE It is believed that Meniere's disease (MD) is associated with vascular disorders, but few studies have reported the relationship between retinal vascular disorders and MD. We evaluated and compared the retinal vascular calibres in patients with MD with healthy subjects matched for age, sex and vascular risk factors using retinal photographs to explore the association between MD and retinal vascular calibre. STUDY DESIGN A prospective study. SETTING Tertiary referral centre. PARTICIPANTS Sixty patients with MD and 62 healthy subjects matched for age, sex and vascular risk factors were enrolled in this study. Twenty-four patients with MD had migraines, and 36 patients with MD did not have migraines. MAIN OUTCOME MEASURE Retinal vascular calibres were calculated and compared not only between patients with MD and healthy subjects but also between subgroups of patients with MD. RESULTS Compared with healthy subjects, patients with MD had a slightly larger retinal artery calibre (126.30±10.45vs 119.61±15.86, p=0.006) and a higher retinal artery/vein ratio (0.79±0.09vs 0.75±0.10, p=0.005). Among patients with MD, those with migraines had a larger retinal artery calibre (130.73±11.55vs 123.35±8.61, p=0.006) than those without migraines. Moreover, the presence of migraines and the high frequency of vertigo attacks appeared to increase the retinal artery calibre. CONCLUSIONS Our study suggests that a relationship exists between retinal vascular calibre and MD. Although the pathophysiological relationship between migraine and MD remains unclear, the presence of migraine attacks may aggravate endolymphatic hydrops (EH) and accelerate the outflow of EH in patients with MD. More extensive studies are required to explore the association between retinal vascular calibre and MD.

Abstract
Different types of inner ear diseases can damage different cochlear subsites by different mechanisms. Steroids administered by different methods are commonly used for treating inner ear diseases. There is reason to believe that dexamethasone (Dex) may reach cochlear subsite targets via different pathways after administration by different methods: Intratympanic (IT), postaural (PA), and intraperitoneal (IP). The purpose of this study was to explore the cochlear concentration and distribution of Dex after administration by different methods. High-performance liquid chromatography-mass spectrometry and immunofluorescence technology were employed to measure and compare the Dex concentration in the perilymph and cochlear tissue and the cochlear distribution of Dex. IT administration resulted in higher Dex concentrations in the perilymph and cochlear tissues than those with the other administration methods. Intratympanic and postaural administration could result in higher Dex concentrations in the organ of Corti than systemic administration, but systemic administration could result in higher Dex concentrations in the stria vascularis than the other administration methods. A decreasing basal-apical gradient of Dex uptake was present in the cochlea after IT but not IP or PA administration. These results indicate that different administration methods result in different Dex distributions, which can be attributed to features of the cochlear vascular system and intracochlear diffusion. Our results provide clinicians with an experimental basis for the use of different steroid injection routes to optimize the effects on inner ear diseases with different target organs.

Abstract
BACKGROUND To assess the current evidence of effectiveness and safety of single-incision mini-slings (MiniArc) versus transobturator midurethral slings in the management of female stress urinary incontinence (SUI). METHODS A systematic search was performed from the electronic databases including PubMed, EMBASE, and Cochrane Library by November 2017. Using RevMan5.3 statistical software, the primary outcomes including subject and objective cure rates at 6 to 24 months follow-up were evaluated. Meanwhile, analysis was also performed for comparing the secondary outcomes such as peri- and postoperative complications, operative data, and quality of life. RESULTS Six randomized controlled trials (RCTs) and 6 retrospective cohort studies involving 1794 patients with SUI were analyzed based on the inclusion criteria. On the basis of our analysis, MiniArc was proven to have a noninferior clinical efficacy compared with transobturator midurethral slings with respect to the objective cure rate (risk ratio [RR] = 0.98, 95% confidence interval [CI] 0.94-1.03, P = .43) and subjective cure rate (RR = 0.97, 95% CI 0.91-1. 04, P = .38). In addition, pooled analysis showed that MiniArc had significantly lower postoperative pain scores (mean difference [MD] = -1.70, 95% CI -3.17 to -0.23, P = .02) and less postoperative groin pain (RR = 0.42, 95% CI 0.18-0.98, P = .04). Moreover, the MiniArc group also had a significantly shorter operation time (MD = -6.12, 95% CI -8.61 to -3.64, P < .001), less blood loss (MD = -16.67, 95% CI -26.29 to -7.05, P < .001), shorter in-patient stay (MD = 1.30, 95% CI -1.74 to -0.86, P < .001), and less urinary retention risk (RR = 1.15, 95% CI 0.46-2.87, P = .77). However, overall evidence was insufficient to suggest a statistically significant difference in the adverse event profile for MiniArc compared with transobturator slings. CONCLUSIONS This meta-analysis indicates that MiniArc is an effective method treating SUI. When compared with transobturator slings, it not only has a similar high cure rates, but also is associated with shorter operation time, less blood loss, more favorable recovery time, lower postoperative pain scores, less postoperative groin pain, less urinary retention, and absence of a visible wound. However, the findings of this study should be further confirmed by well-designed prospective RCTs with a larger patient series.

Abstract
Treatment options for simple renal cyst (SRC) include open surgery, laparoscopy with decortication, or percutaneous aspiration with or without sclerotherapy. Though laparoscopic unroofing achieves better results than percutaneous sclerotherapy, the reported recurrence rate is still up to 19%. Thus, it is necessary to find methods to reduce the recurrence rate.To investigate whether the perirenal pedicled fat tissue wadding technique during retroperitoneal laproscopic deroofing (RLD) of SRC affects the incidence of recurrence.A retrospective analysis was carried out on clinical data of 254 patients with SRC treated by RLD in our hospital from 2008 to 2016. Among these patients,119 had a simple retroperitoneal deroofing (SRD) and 135 received a retroperitoneoscopic deroofing with wadding of the cyst using perirenal fat tissue (RDCW). The recurrence rate and variables, as well as perioperative complications, were compared. To further explore the potential variables influencing cyst recurrence rate, univariate and multivariate regression analyses were applied.A total of 251 patients were included in the analysis. The operation was successfully completed laparoscopically in all cases with no conversion to open surgery. No mortality or significant complication occurred in both groups. After a median follow-up of 38.67 months, we noted 41 recurrences. According to the univariate and multivariate regression analyses, patients managed with the wadding technique had superior recurrence-free survival (RFS), compared with patients in SRD group (log-rank P = .03 and P = .04, respectively). Moreover, patients with single renal cyst had a lower recurrence rate, compared with patients with multiple renal cysts (log-rank P < .01). Regarding the operation time, blood loss, and hospital stay, no statistically significant difference was found between 2 groups (P values .13, .30, and .75, respectively). However, less postoperative drainage and shorter postoperative interval until tube removal (P = .04) were observed in RDCW group.The perirenal pedicled fat tissue wadding technique can decrease the cyst recurrence rate and RCDW represents an effective and safe treatment option in the management of renal cysts.
