Abstract
BACKGROUND Hong Kong catfish (Clarias fuscus) is an ecologically and economically important species that is widely distributed in freshwater regions of southern China. Hong Kong catfish has significant sexual growth dimorphism. The genome assembly of the Hong Kong catfish would facilitate study of the sex determination and evolution mechanism of the species. RESULTS The first high-quality chromosome-level genome of the Hong Kong catfish was constructed. The total genome was 933.4 Mb, with 416 contigs and a contig N50 length of 8.52 Mb. Using high-throughput chromosome conformation capture (Hi-C) data, the genome assembly was divided into 28 chromosomes with a scaffold N50 length of 36.68 Mb. A total of 23,345 protein-coding genes were predicted in the genome, and 94.28% of the genes were functionally annotated in public databases. Phylogenetic analysis indicated that C. fuscus and Clarias magur diverged approximately 63.7 million years ago. The comparative genome results showed that a total of 60 unique, 353 expanded and 851 contracted gene families were identified in Hong Kong catfish. A sex-linked quantitative trait locus identified in a previous study was located in a sex-determining region of 30.26 Mb (0.02 to 30.28 Mb) on chromosome 13 (Chr13), the predicted Y chromosome. This QTL region contained 785 genes, of which 18 were identified as sex-related genes. CONCLUSIONS This study is the first to report the chromosome-level genome assembly of Hong Kong catfish. The study provides an excellent genetic resource that will facilitate future studies of sex determination mechanisms and evolution in fish.

Abstract
Non-small cell lung cancer (NSCLC) is one of the most severe malignant tumors worldwide. Lobectomy and systematic nodal dissection remain the standard treatment for stageⅠNSCLC. Stereotactic body radiotherapy (SBRT) has become the standard treatment for medically inoperable patients. Though the prognosis of stage Ⅰ NSCLC patients is generally good, there are still about 20% of patients with local recurrence and distant metastasis. There is significant heterogeneity in the prognosis and failure phenotype of patients, which cannot be precisely distinguished by the pathological TNM classification system. Identification of the risk factors for the prognosis of patients with stage Ⅰ NSCLC is a key step to realize the treatment from experience to precision. Screening the high-risk patients will facilitate to individually develop the adjuvant therapy strategy after surgery or SBRT and improve the overall curative effect. There are many factors that are significantly related to the prognosis of stage Ⅰ NSCLC including individual factors such as gender, age, and systemic inflammatory biomarkers; treatment-related factors such as the extent of surgical resection of the primary tumor and lymph nodes, the choice of different radiation rays, and different dose fractionation; and tumor-related factors such as imaging information, pathology information; and molecular biology information. This review will analyze the treatment failure phenotype and prognostic factors of stageⅠ NSCLC in various perspectives such as individual-, tumor- and treatment-related factors.

Abstract
Abstract
Background
The incidence of diabetes mellitus and coronary artery disease continue to rise and collectively comprise two of the most prevalent and costly diseases worldwide. The goal of this study is to report the prognosis of young patients with diabetes presented with acute myocardial infarction (AMI).
Methods
This is a retrospective observational cohort study that included consecutive patients aged 18–45 years who underwent cardiac catheterization for AMI between 2006 and 2016 in an integrated healthcare system in Southern California. The prognosis of patients with diabetes were compared to those without diabetes.
Results
A total of 1,560 patients (average age 40.2±5.3 years, 25.6% female) presenting with AMI were included. Of these 272 (17.4%) had diabetes. Diabetics were older (41.1±4.4 vs 40.0±5.4 years), more likely to be female (32.4% vs 24.1%, p=0.006), Hispanic (51.5% vs 40.5%, p<0.001), have a higher body mass index (BMI) (33.6±7.1 vs 31.2±6.8kg/m2, p<0.001), have hypertension (HTN) (67.6% vs 23.8%, p<0.001), hyperlipidemia (HLD) (78.3% vs 24.1%, p<0.001), peripheral vascular disease (9.9% vs 1.9%, p<0.001), chronic kidney disease (CKD) (23.2% vs 2.7%, p<0.001), hypothyroidism (7% vs 4%, p=0.034), and prior strokes (4.4% vs 2.2%, p=0.034).
On multivariate analysis accounting for other cardiovascular risk factors, the association remained significant (OR 1.82, 95% CI 1.04–3.19, p=0.036). At a median follow-up of 5.8 years (interquartile range 3.7–8.7 years), diabetes was independently associated with increased all-cause mortality (Hazard ratio [HR] 3.10, 95% CI 1.68–5.69, p<0.001) when adjusting for age, sex, race, BMI, HTN, HLD, CKD, hypothyroidism, prior stroke, and ACS etiology. In a propensity score matched cohort, diabetes remained significantly associated with all-cause mortality (HR 5.29, 95% CI 2.34–12.02, p<0.001).
Conclusion
Diabetes is an independent predictor of increased mortality in young adults <45 years old presenting with AMI.

Abstract
Objective: To investigate the effect of programmed death receptor (PD)-1 antibody therapy in patients with hepatitis B-associated liver cancer. Methods: Data of 29 chronically infected HBV patients with liver cancer who received PD-1 antibody combined with tyrosine kinase inhibitor in the Department of Infectious Diseases of the Fifth Medical Center of PLA General Hospital from March 2020 to January 2021 were selected. At the same time, all of the above-mentioned hepatitis B virus (HBV) patients were treated with nucleos(t)ide analogues. Patients clinical diagnostic data, laboratory test results, tumor response and the incidence of adverse reactions were collected retrospectively to understand the overall safety, therapeutic anti-tumor effect, HBV changes condition and the correlation between HBV changes and anti-tumor PD-1 antibody efficacy, high viral load treatment condition, and HBV reactivation safety issues. Statistical analysis was performed by non-parametric rank sum test. Results: Therapeutic anti-tumor effect and safety profile were good in patients. The complete remission rate was reached 27.6%. Adverse reactions were mostly mild, and the incidence of serious adverse reactions was low. After 12 weeks of follow-up, HBV DNA and hepatitis B surface antigen (HBsAg) was quantitatively decreased (P < 0.05). HBV DNA and HBsAg were decreased more significantly in patients with progressive disease (PD), stable disease (SD) and partial response (PR) (P < 0.05). Five patients with HBV DNA ≥ 10(4) IU/ml had responded well to the tumor treatment without serious adverse reactions. One patient had a slight increase in HBV DNA and alanine aminotransferase, while there was no HBV reactivation and correlated liver damage. Conclusion: Patients with HBV-associated liver cancer who received combined therapy have good anti-tumor efficacy and safety profile. PD-1 treatment has a certain effect on HBV. Compared with non-responders, patients with tumor response have better antiviral treatment efficacy. The safety of treatment in patients with high viral load is manageable, and there are no safety issues related to HBV reactivation.

Abstract
OBJECTIVE To investigate the changes in the size of the penis after radical prostatectomy (RP) and the possible influencing factors. METHODS This study included 45 cases of RP for PCa performed by the same surgeon from January to June 2019. Before and at 2 weeks after surgery, we measured the stretched penile length (SPL), flaccid penile length (FPL) and penile circumference of the patients. We conducted an IIEF-5 questionnaire investigation on the preoperative characteristics of the patients and their attitudes towards postoperative penile rehabilitation. We also analyzed the factors associated with the postoperative changes in the size of the penis. RESULTS Compared with the baseline, the postoperative SPL ([9.72 ± 1.87] vs [7.80 ± 1.57] cm, P = 0), FPL ([6.26 ± 1.14] vs [5.13 ± 1.10] cm, P = 0) and penile circumference ([7.69 ± 0.83] vs [7.26 ± 0.78] cm, P = 0.012) were decreased significantly, by (1.92 ± 0.12) cm, (1.13 ± 0.09) cm and (0.43 ± 0.08) cm, respectively. The age of the patients was significantly correlated with the change of the FPL (P = 0.042), but not the other factors with the change of the penile size. Twenty-six (57.7%) cases of severe and moderate ED were observed in the patients postoperatively. Those with better preoperative sexual function took a more positive attitude towards penile rehabilitation and treatment postoperatively (n = 3, 75.0%). CONCLUSIONS The penile size of the PCa patient is decreased markedly after radical prostatectomy, with a significant correlation between the patient's age and the postoperative change of the flaccid penile length. The patients with better preoperative sexual function are more likely to seek penile rehabilitation and treatment postoperatively.

Abstract
With the rapid development of global tourism, traveling gradually becomes an important part of daily lives, and travelers'health is paid more and more attention. Traveler's diarrhea (TD) is one of the most common diseases among international or trans-regional travelers, which causes great disease and economic burdens. Currently, there is still a lack of systematic studies on the correlation between parasites and TD. The review mainly summarizes intestinal protozoa and helminth infections among patients with TD, so as to provide insights into the development of the control measures for parasitic diseases associated with TD and the prevention of risk factors before the journey to and during the journey of the areas endemic for parasitic diseases.

Abstract
Background: Of patients with upper urinary tract urothelial carcinoma (UTUC), 22–47% developed bladder recurrence after radical nephroureterectomy. Furthermore, the effect of surgery for UTUC-bladder cancer (BC) has not been well validated. The aim of this study was to assess the impact of standard primary BC surgical strategy on survival of patients diagnosed with UTUC-BC. Patients and Methods: A total of 676 UTUC-BC patients and 197,753 primary BC patients diagnosed from 2004 to 2016, were identified based on the SEER database. The Kaplan-Meier method and the Fine and Gray competing risks analysis were performed to assess overall survival (OS) and cancer-specific mortality (CSM). Multivariate Cox regression model and competing risks regression model were used to identify independent risk factors. Propensity score matching (PSM) was also performed to adjust potential confounding factors. Results: The baseline characteristics and survival outcomes of the two BC patient cohorts are quite different. For UTUC-BC patients, no significant difference in OS (NMIBC: p = 0.88; MIBC: p = 0.98) or cumulative incidence of CSM (NMIBC: p = 0.12; MIBC: p = 0.96) were noted for various surgical procedures. Local tumor treatment and partial cystectomy for UTUC-NMIBC patients produced lower 1-year (6.1%) and 3-year CSM (16.2%). Radical cystectomy for UTUC-MIBC patients produced lower 1-year (11.8%) but higher 3-year CSM (62.7%). After PSM for covariates, UTUC-BC patients still had a worse prognosis after surgery compared with primary BC patients. Based on regression models, older age, advanced T stage, N positive disease, M positive disease, and shorter interval between UTUC and BC were identified as independent risk factors for UTUC-BC patients. Conclusion: Standard primary BC surgical strategy did not provide significant survival benefit for UTUC-BC patients. Compared with primary BC patients, UTUC-BC patients had a worse prognosis after surgery, suggesting that current primary BC surgical guidelines are not entirely appropriate for UTUC-BC patients. Our findings underscore the continued importance and need for better prognosis and improved guidelines for management of UTUC-BC patients.

Abstract
This study investigated the clinical activity of abiraterone plus prednisone in docetaxel-naïve and docetaxel-resistant Chinese patients with metastatic castration-resistant prostate cancer (mCRPC). A total of 146 patients with docetaxel-naïve group (103 cases) and docetaxel-resistant group (43 cases) were enrolled from the Shanghai Cancer Center (Shanghai, China) in this retrospective cohort study. The efficacy endpoints were prostate-specific antigen response rate, prostate-specific antigen progression-free survival, clinical/radiographic progression-free survival, and overall survival in response to abiraterone plus prednisone. Significantly higher prostate-specific antigen response rate was found in docetaxel-naïve group (54.4%, 56/103) compared to docetaxel-resistant group (34.9%, 15/43) (P = 0.047). In addition, significantly higher median prostate-specific antigen progression-free survival (14.0 vs 7.7 months, P = 0.005), clinical or radiographic progression-free survival (17.0 vs 12.5 months, P = 0.003), and overall survival (27.0 vs 18.0 months, P = 0.016) were found in docetaxel-naïve group compared to docetaxel-resistant group, respectively. The univariate and multivariate analyses indicated that lower albumin and visceral metastases were independent significant predictors for shorter overall survival. To sum up, our data suggested that abiraterone plus prednisone was efficient in both docetaxel-naïve and docetaxel-resistant Chinese patients. Moreover, higher PSA response rate and longer overall survival were observed in the docetaxel-naïve group, which suggested that abiraterone was more effective for docetaxel- naïve patients than for docetaxel failures.

Abstract
OBJECTIVE To characterize the trehalase gene in Thelazia callipaeda through screening the annotated data of the T. callipaeda genome, and to investigate the biological characteristics of the trehalase gene-coding protein. METHODS The trehalase gene was screened from the T. callipaeda genome and subjected to validation by using a PCR assay. The structural features of the coding protein were analyzed with bioinformatics tools, including hydrophobicity, transmembrane region, signal peptides, conserved domains, as well as the secondary and tertiary structures and the antigen epitope. Homology analysis of the amino acid sequences was performed, and the phylogenetic tree was built by the MEGA X software. In addition, the protein-protein interaction network was deduced from the STRING database. RESULTS The sequence of the trehalase gene with the complete CDS region was obtained from T. callipaeda genome, which had a length of 1 638 bp and encoded 545 amino acids. The encoded protein was predicted to have a molecular weight of 63 478.48 ku and be a secretory protein. The 5' domain of the encoded protein contained a signal peptide without transmembrane regions, and was predicted to contain 7 antigen epitopes. Based on the protein-protein interaction network of nematodes in the STRING database, the protein-protein interaction network of the trehalase gene of T. callipaeda was deduced, and 27 interactions covering 10 genes were identified. CONCLUSIONS A trehalase gene is successfully identified in T. callipaeda genome and its coding protein receives a bioinformatics analysis, which provides insights into the research on the biological functions of the protein and the screening of vaccine candidates for thelaziasis callipaeda.

Abstract
The aims of this study were to determine the prognostic value of primary tumor surgery and identify optimal candidates for such surgery among patients with seminoma and distant metastasis at diagnosis. We identified 521 patients with seminoma and distant metastasis at diagnosis between 2004 and 2014 from the Surveillance, Epidemiology, and End Results database. Among these patients, 434 had undergone surgery, whereas 87 had not. The prognostic value of primary tumor surgery was assessed by Kaplan–Meier methods, log-rank analyses, and multivariate Cox's proportional hazards model. Survival curves and forest plots were also plotted. Survival analysis indicated that patients who underwent surgery had a better 5-year overall survival and cancer-specific survival than those who did not. Multivariate analyses demonstrated that primary tumor surgery is an independent prognostic factor for overall survival and cancer-specific survival, along with age at diagnosis, M stage, and marital status. In addition, primary tumor surgery still had considerable prognostic value in the subgroup of patients with lymph node metastasis. Further, forest plots demonstrated that patients with M1a stage, N1 or N2–3 stage, and a younger age at diagnosis (<60 years) may benefit from primary tumor surgery. In conclusion, our findings indicate that primary tumor surgery is correlated with improved survival in patients with seminoma and distant metastasis. Furthermore, primary tumor surgery is an independent prognostic indicator for patients with seminoma and distant metastasis.

Abstract
BACKGROUND Pelvic lymphadenectomy (PLND) is an integral part of curative surgery for high-risk non-muscle invasive and muscle-invasive bladder cancer. The therapeutic value of extended PLND is controversial. METHODS We conducted a comprehensive online search in PubMed, EMBASE, and the Cochrane Library databases for relevant literature directly comparing extended PLND (e-PLND) with non-extended PLND (ne-PLND) from database inception to June 2019. We performed the meta-analysis to evaluate the impact of PLND templates on recurrence-free survival (RFS), disease-specific survival (DSS), overall survival (OS), rates of postoperative major complications, and mortality within 90 days of surgery. RESULTS A total of 10 studies involving 3979 patients undergoing either e-PLND or ne-PLND were included. The results showed that e-PLND was significantly associated with better RFS (HR 0.74, 95% CI 0.62-0.90, p = 0.002) and DSS (HR 0.66, 95% CI 0.55-0.79, p < 0.001). However, no correlation was found between e-PLND template and a better OS (HR 0.93, 95% CI 0.55-1.58, p = 0.79). Postoperative major complications were similar between e-PLND group and ne-PLND group, as was mortality within 90 days of surgery. CONCLUSION e-PLND template is correlated with favorable RFS and DSS outcomes for patients with bladder cancer. e-PLND did not have more postoperative major complications than did ne-PLND.

Abstract
Objective: To investigate the association between tumor PD-L1 expression and patient survival to determine whether PD-L1 represents an independent prognostic feature for patients with non-metastatic clear cell renal cell carcinoma (RCC). Patients and Methods: The tissue bank of the Fudan University Shanghai Cancer Center was queried to identity tissue samples of patients treated with radical nephrectomy, for non-metastatic sporadic clear cell RCC (ccRCC) between 2008 and 2015. Real-time polymerase chain reaction and immunohistochemistry staining was performed to detect the expression level of PD-L1 in paired cancer tissue and paracancerous tissue. Results: Three-hundred-and-thirty patients were enrolled in this study, with a mean age of 55.0 years at surgery and a mean tumor size of 5.2 cm. Two-hundred-and-forty-two (73.3%) and 88 (26.7%) patients showed a high and low expression of PD-L1 mRNA, respectively, while 254 patients had positive PD-L1 immunohistochemistry staining. Two-hundred-and-ninety-two patients had consistent results for mRNA and the PD-L1 protein based on these different detection methods. Patients with high PD-L1 expression were more likely to exhibit adverse pathologic features including an advanced T stage (P = 0.002) and lymph node metastasis (P = 0.044). The Kaplan-Meier curves of PFS and OS stratified by PD-L1 expression had a statistically significant difference. PD-L1 expression maintained a significant predictive role for PFS and OS in the multivariate cox model. Conclusions: Our data suggests that PD-L1 correlates with prognosis in RCC and targeting the PD-1/PD-L1 pathway should be considered in the treatment of RCC patients.

Abstract
OBJECTIVE To investigate the dynamics changes of the myeloid-derived suppressor cells (MDSCs) and regulatory T (Treg) cells in mice infected with Echinococcus granulosus and explore the possible biological significance. METHODS Thirty female BALB/c mice of 6 weeks old were randomly divided into the infection and control groups, of 15 mice in each group. Mice in the infection group were intraperitoneally injected with 2 000 E. granulosus protoscoleces, while those in the control group were injected with the same volume of physiological saline. Mouse liver white blood cells were harvested 3 (early stage), 6 (medium stage) and 12 months (late stage) post-infection, and the proportions of MDSCs, their subpopulations (M-MDSCs and PMN-MDSCs) and Treg cells were assessed by flow cytometry. RESULTS The proportions of MDSCs were (1.61 ± 0.36)%, (5.68 ± 0.69)% and (16.18 ± 0.69)% in mouse liver white blood cells in the infection group 3, 6 and 12 months post-infection with E. granulosus, and (2.19 ± 0.42)%, (0.99 ± 0.07) % and (4.18 ± 0.84)% in the control group, and there were significant differences in the proportion of the MDSCs in mouse liver white blood cells between the infection and control groups 6 and 12 months post-infection (P < 0.01). The proportions of M-MDSCs were (0.69 ± 0.27)%, (5.30 ± 0.72)% and (10.75 ± 0.29)% in mouse liver white blood cells in the infection group 3, 6 and 12 months post-infection, and (0.42 ± 0.24)%, (0.69 ± 0.02)% and (2.12 ± 0.13)% in the control group, and there were significant differences in the proportion of the M-MDSCs in the mouse liver white blood cells between the infection and control groups 6 and 12 months post-infection (P < 0.01). The proportions of PMN-MDSCs were (0.93 ± 0.23)%, (0.32 ± 0.02)% and (5.14 ± 1.03)% in mouse liver white blood cells in the infection group 3, 6 and 12 months post-infection, and (1.77 ± 0.26)%, (0.28 ± 0.05)% and (1.99 ± 0.90)% in the control group, and there were significant differences in the proportion of PMN-MDSCs in mouse liver white blood cells between the infection and control groups 3 and 12 months post-infection (P < 0.05). The proportions of Treg cells were (3.35 ± 0.14)%, (6.24 ± 0.38)% and (3.41 ± 0.07)% in mouse liver white blood cells in the infection group 3, 6 and 12 months post-infection, and (3.48 ± 0.46)%, (3.65 ± 0.45)% and (3.12 ± 0.12)% in the control group, and there were significant differences in the proportion of Treg cells in mouse liver white blood cells between the infection and control groups 6 and 12 months post-infection (P < 0.01). CONCLUSIONS The percentages of both MDSCs and Treg cells increase in mouse liver white blood cells 6 and 12 months post-infection with E. granulosus, and a more remarkable increase is seen in the percentage of MDSCs, which is mainly found in M-MDSCs. These findings suggest that M-MDSCs may play a major immunosuppressive role in the medium and late stages of E. granulosus infection in mice.

Abstract
The tumorigenic role and underlying mechanisms of lipid accumulation, commonly observed in many cancers, remain insufficiently understood. In this study, we identified an AMP-activated protein kinase (AMPK)-GATA-binding protein 3 (GATA3)-enoyl-CoA hydratase short-chain 1 (ECHS1) pathway that induces lipid accumulation and promotes cell proliferation in clear cell renal cell carcinoma (ccRCC). Decreased expression of ECHS1, which is responsible for inactivation of fatty acid (FA) oxidation and activation of de novo FA synthesis, positively associated with ccRCC progression and predicted poor patient survival. Mechanistically, ECHS1 downregulation induced FA and branched-chain amino acid (BCAA) accumulation, which inhibited AMPK-promoted expression of GATA3, a transcriptional activator of ECHS1. BCAA accumulation induced activation of mTORC1 and de novo FA synthesis, and promoted cell proliferation. Furthermore, GATA3 expression phenocopied ECHS1 in predicting ccRCC progression and patient survival. The AMPK-GATA3-ECHS1 pathway may offer new therapeutic approaches and prognostic assessment for ccRCC in the clinic. SIGNIFICANCE: These findings uncover molecular mechanisms underlying lipid accumulation in ccRCC, suggesting the AMPK-GATA3-ECHS1 pathway as a potential therapeutic target and prognostic biomarker.

Abstract
Objective: To investigate the short-term efficacy and adverse events of chemotherapy combined with androgen-deprivation therapy in high-volume metastatic hormone sensitive prostate cancer. Methods: From March 2015 to August 2017, 55 patients with high-volume metastatic hormone sensitive prostate cancer were enrolled at Department of Urology, Fudan University Shanghai Cancer Center receiving chemotherapy combined with androgen-deprivation therapy. The age was 65(8) years (M(Q(R))) (range: 46 to 79 years). Patients were enrolled in the study for continuous androgen-deprivation therapy (medical or surgical castration), combined with docetaxel 75 mg/m(2) intravenous injection on the first day, repeated every 21 days (6 cycles). Endpoints included overall survival, progression-free survival of prostate cancer, prostate specific antigen (PSA) response rate, and adverse events. Results: The follow-up time was 21.2(11.7) months. The PSA value before chemotherapy was 144.9(415.3) μg/L. The days in patients undergoing androgen deprivation therapy before chemotherapy was 14(23) days. Four patients (7.3%) presented 0 in Eastern Cooperative Oncology Group scoring system and 51 patients(92.7%) presented 1. Thirty-nine patients (70.9%) completed more than 6 cycles of combined chemotherapy, 17 patients (30.9%) showed PSA<0.2 μg/L at 6 months after treatment, and 14 patients (25.5%) showed PSA<0.2 μg/L at 12 months after treatment. Twenty-eight patients (50.9%) had grade 3 to 4 neutropenia and 1 patient (1.8%) developed infectious neutropenia and died. Nausea and vomit occurred in 16 patients (29.1%). Twelve patients (21.8%) underwent dose adjustment due to adverse events in blood system. Conclusions: The short-term effect was confirmed in high-volume metastatic hormone sensitive prostate cancer using chemotherapy combined androgen-deprivation therapy, and the long-term effect remains to be seen. Myelosuppression during chemotherapy requires close attention, and taking timely examination is recommended.

Abstract
OBJECTIVE To investigate the attitudes of prostate cancer (PCa) patients towards postoperative penile rehabilitation and their influencing factors. METHODS Seventy-nine PCa patients underwent radical prostatectomy from January through June 2017 and all received a questionnaire investigation before surgery on IIEF-5 and their attitudes towards postoperative penile rehabilitation. We analyzed the reasons for the patients' rejection of postoperative penile rehabilitation. RESULTS Totally 56 (71%) of the patients accepted and the other 23 (29%) refused postoperative penile rehabilitation. The factors influencing their attitudes towards penile rehabilitation mainly included age (P = 0.023), income (P = 0.040), tumor stage (P = 0.044), and preoperative sexual activity (P = 0.004). The patients who accepted penile rehabilitation had significantly higher IIEF-5 scores than those who refused it (14.75 ± 0.88 vs 8.48 ± 1.16, P = 0.000 2). During the follow-up period, only 29 (36.7%) of the patients bought the vacuum erection device but not the other 50 (63.3%). The tumor stage (P = 0.004), income (P < 0.01) and preoperative androgen-deprivation therapy (P = 0.039) significantly influenced the patients' decision on the purchase of the device. Relevant admission education achieved a 45% decrease in the number of the patients unwilling to accept penile rehabilitation for worrying about its negative effect on cancer treatment, a 25% decrease in those rejecting penile rehabilitation because of age, and a 20% decrease in those refusing it due to the tumor stage. The cost of treatment was an important reason for the patients' rejection of postoperative penile rehabilitation. CONCLUSIONS The tumor stage and income are the main factors influencing PCa patients' decision on postoperative penile rehabilitation. Relevant admission education and reduced cost of rehabilitation are important for popularization of postoperative penile rehabilitation in PCa patients.

Abstract
Objective: To investigate the safety and efficacy of radiofrequency ablation (RFA) with percutaneous iohexol-ethanol injection (PIEI), compared with RFA plus transcatheter arterial chemoembolization (TACE) for patients with primary liver cancer(PLC)in high-risk locations. Methods: From January 2012 to December 2014, 54 patients with PLC in high-risk locations were enrolled. They were divided into Group A (RFA combined with PIEI) and Group B (RFA plus TACE). The efficacy and adverse events were assessed. Results: 54 patients had 74 lesions in high-risk locations. There were 26 cases with 40 lesions in Group A, and 28 cases with 34 lesions in Group B. The complete ablation rate of Group A was significantly higher than that of Group B (92.5% vs 70.6%, P=0.014). The two-year local tumor progressionrateand two-year overall survival rate were similar between these two groups (Group A 20.0% vs Group B 38.2%, P=0.083; 90.3% vs 84.3%, P=0.523). Furthermore, the surgery-related severe adverse events of Group A (7.1%, one case of liver abscess and one case ofhematobilia) were more common than that of Group B (0%, P=0.491). No significant differences were found in common adverse events including fever, pain, elevation of aminotransferase and bilirubin. Conclusions: Compared with RFA plus TACE, RFA plus PIEI resulted inbetter complete ablation rate in patients with primary liver cancer in high risk locations. Prospective, randomized, controlled trials are warranted for further evaluation.

Abstract
The role of adjuvant hormonal therapy and optimized regimens for high-risk localized prostate cancer after radical prostatectomy remains controversial. Herein, the clinical trial CU1005 prospectively evaluated two regimens of maximum androgen blockage or bicalutamide 150 mg daily as immediate adjuvant therapy for high-risk localized prostate cancer. Overall, 209 consecutive patients were recruited in this study, 107 of whom received 9 months of adjuvant maximum androgen blockage, whereas 102 received 9 months of adjuvant bicalutamide 150 mg. The median postoperative follow-up time was 27.0 months. The primary endpoint was biochemical recurrence. Of the 209 patients, 59 patients developed biochemical recurrence. There was no difference between the two groups with respect to clinical characteristics, including age, pretreatment prostate-specific antigen, Gleason score, surgical margin status, or pathological stages. The maximum androgen blockage group experienced longer biochemical recurrence-free survival (P = 0.004) compared with the bicalutamide 150 mg group. Side-effects in the two groups were similar and could be moderately tolerated in all patients. In conclusion, immediate, 9-month maximum androgen blockage should be considered as an alternative to bicalutamide 150 mg as adjuvant treatment for high-risk localized prostate cancer patients after radical prostatectomy.

Abstract
Background Genetic polymorphism was hypothesized to be reason of variation in prostate cancer incidence among different racial group. Based on that published data on the association of prostate cancer susceptibility with polymorphisms in genes encoding Glutathione S-transferases (GSTs) were inconclusive, the aim of this study was to more precisely address the role of GSTs polymorphisms (especially, GSTT1 and GSTM1 deletions) on prostate cancer risk in Asian descent. Methods A meta-analysis including 8 articles with 711 cases and 1122 controls for GSTT1 and 1098 cases and 1588 controls for GSTM1 was performed. Results Significantly increased prostate cancer risk was found among subjects carrying GSTM1 null genotype (odds ratio (OR) = 1.403; 95% confidence interval (CI) = 1.088 – 1.808) but not among subjects carrying GSTT1 deletion genotype (OR = 0.959; 95%CI = 0.709 – 1.297). When stratified by country, the null genotype of GSTT1 neither increased nor decreased prostate cancer risk significantly in China (OR = 1.355; 95%CI = 0.895 – 2.049), Japan (OR = 0.812; 95%CI = 0.545 – 1.211), and Korea (OR = 1.056; 95%CI = 0.727 – 1.534). While significant association of elevated prostate cancer risk with GSTM1 deletion were found in China (OR = 1.665; 95%CI = 1.324 – .094) and Korea (OR = 1.914; 95%CI = 1.311 – 2.793) but not in Japan (OR = 0.980; 95%CI = 0.726 – 1.321). Conclusion In summary, this meta-analysis suggested that the null genotype of GSTM1 rather than GSTT1 may be involved in the etiology of prostate cancer in Asian population.

Abstract
Castration-resistant prostate cancer (CRPC) remains the most critical challenge in the clinical management of prostate cancer (PCa). Reactive stromal changes in PCa are likely involved in the emergence of CRPC. In the present study, we identified a novel oncogene termed COL6A1 which was upregulated in the reactive stroma of CRPC. We established an androgen-independent LNCaP (LNCaP-AI) cell line in steroid-reduced (SR) medium within 2 months. We examined COL6A1 expression with western blot during the LNCaP-AI induction, and studied the function of COL6A1 in vitro and in vivo. Immunohistochemical staining of COL6A1 was performed in ten pairs of androgen-sensitive PCa and CRPC samples. We demonstrated that COL6A1 expression was markedly increased in LNCaP-AI cells and CRPC tissues compared with LNCaP cells and paired androgen-sensitive PCa specimens. In vitro, COL6A1 knockdown resulted in G1-S cell cycle arrest and descended vitality. Overexpression of COL6A1 was associated with accelerated S phase entry and elevated vitality in prostate cancer cells. COL6A1 also promoted tumorigenesis of LNCaP cells in vivo. Taken together, these data suggest an important role of COL6A1 in the molecular etiology of castration-resistant prostate cancer, and support the potential use of COL6A1 in CRPC therapy.

Abstract
Estrogen is a crucial hormone for osteoclast inhibition and for preventing osteoporosis. However, the hormone's role in osteoblast growth and differentiation remains unclear. The complexity of estrogen's role in guiding osteoblast behavior arises partly from crosstalk with other signaling pathways, including Wnt signaling. In this study, we show that the Wnt agonist, LiCl, induced Fhl1 gene expression, which substantially enhanced osteoblast differentiation. Staining with alizarin red revealed that MC3T3-E1 mineralization was enhanced by overexpression of Fhl1. In addition, Fhl1 promoted the expression of the osteogenic markers, Runt-related transcription factor 2 (Runx2), osteocalcin (OCN), and osteopontin (OPN), whereas MC3T3-E1 cells with gene knockdown of Fhl1 exhibited limited mineralization and expression of Runx2, OCN, and OPN. We further demonstrate evidences from quantitative reverse transcription real-time polymerase chain reaction and reporter assay that Fhl1 expression was synergistically stimulated by estrogen (E2) and LiCl, but reduced by the estrogen-receptor inhibitor fulvestrant (ICI 182,780). However, estrogen could not enhance osteogenesis while Fhl1 expression was knocked down. Because estrogen and Wnt signaling frequently interact in developmental processes, we propose that Fhl1 can be an acting molecule mediating both signaling pathways during osteogenesis.

Abstract
OBJECTIVE To investigate whether visceral obesity is associated with certain histological subtypes of renal cell carcinoma (RCC) ina multicentre Chinese cohort. PATIENTS AND METHODS A kidney tumour database was created using three tertiary centres in China; 487 patients were enrolled presenting with localised RCC and complete computer tomography(CT)/magnetic resonance imaging (MRI) information. A single-slice CT image was used to measure the area of visceral and subcutaneous adipose tissues in each patient. Statistical methods were used to analyse clear-cell RCC (ccRCC) and non-clear-cell RCC (non-ccRCC) as they relate to visceral fat area (VFA) and other risk factors, such as age, gender, tumour size, diabetes, hypertension, total fat area (TFA) and body mass index (BMI). RESULTS In all, 418 patients had a ccRCC subtype and 69 had a non-ccRCC subtype. For all the patients with RCC, the mean VFA was 102 cm2, while mean BMI was 24 kg/m2. The mean VFA was greater in ccRCC than non-ccRCC patients by 25 cm2. There were significant differences in the mean VFA and TFA between patients with ccRCC and those with non-ccRCC.Multivariate analysis showed that the presence ofVFA was more important than the effects of BMI and Type 2 diabetes on pathology prediction. In patients with a normal BMI, those with a higher quartile of VFA were more likely to develop ccRCC than those with a low VFA. CONCLUSIONS Increased visceral fat was found to be associated with ccRCC and the significance of VFA outweighed the effects of BMI and Type 2 diabetes for the prediction of RCC pathology in multivariate analyses. As a result, VFA could constitute a primary explanation for the link between obesity and ccRCC.

Abstract
Spectroscopic characterization of a Ho:LuVO4 crystal grown by the Czochralski method has been performed, including the absorption and emission spectra. We demonstrate a 2 μm room temperature Ho:LuVO4 laser, resonantly pumped by a 1.94 μm Tm:YAP laser. By use of an output coupler with T=10% transmission, the Ho:LuVO4 laser generated continuous-wave output power of 2.5 W at 2074.18 nm, with a beam quality factor of Mx2=My2=1.3, for a total incident pump power of 19.4 W. The slope efficiency with respect to the pump power was 17.6%, and the optical-to-optical efficiency was 12.9%. Moreover, we obtained a Ho:LuVO4 laser that operated at 2073.77 and 2055.27 nm, by using different output couplers with transmissions of T=15 and 30%.

Abstract
The DOC-2/DAB2 interactive protein (DAB2IP) is a member of the Ras GTPase-activating protein family. It has been shown to be often downregulated and a poor prognostic factor in several human malignancies. In this study, we analyzed the clinicopathological features and outcomes of DAB2IP expression in 135 patients with urothelial carcinoma of the bladder (UCB) treated by radical cystectomy plus bilateral lymph node dissection, and evaluated the effect of DAB2IP knockdown in vitro using the MTT method, colony formation assay, cell cycle assay, and cell migration and invasive assay. We found low expression of DAB2IP was significantly associated with high pathological stage (P = 0.002), high pathological grade (P = 0.02), tumor size more than 3 cm (P = 0.04), and presence of histological variants (P = 0.01). DAB2IP was an independent prognostic factor of disease recurrence (hazard ratio, 2.67; P = 0.034) and cancer-specific survival (hazard ratio, 2.79; P = 0.038). Knockdown of DAB2IP could promote cell proliferation, migration, and invasion. Downregulation of DAB2IP could activate the ERK and Akt pathways and was correlated with the expression of epithelial–mesenchymal transition markers, such as E-cadherin and vimentin. In conclusion, downregulation of DAB2IP is associated with features of biologically aggressive UCB and results in cell proliferation, migration, and invasion of bladder cancer. DAB2IP may serve as a promising biomarker in patients with UCB treated by radical cystectomy and bilateral lymph node dissection.

Abstract
Using a population-based cancer registry, Thuret et al. developed 3 nomograms for estimating cancer-specific mortality in men with penile squamous cell carcinoma. In the initial cohort, only 23.0% of the patients were treated with inguinal lymphadenectomy and had pN stage. To generalize the prediction models in clinical practice, we evaluated the performance of the 3 nomograms in a series of penile cancer patients who were treated with definitive surgery. Clinicopathologic information was obtained from 160 M0 penile cancer patients who underwent primary tumor excision and regional lymphadenectomy between 1990 and 2008. The predicted probabilities of cancer-specific mortality were calculated from 3 nomograms that were based on different disease stage definitions and tumor grade. Discrimination, calibration, and clinical usefulness were assessed to compare model performance. The discrimination ability was similar in nomograms using the TNM classification or American Joint Committee on Cancer staging (Harrell's concordance index = 0.817 and 0.832, respectively), whereas it was inferior for the Surveillance, Epidemiology and End Results staging (Harrell's concordance index = 0.728). Better agreement with the observed cancer-specific mortality was shown for the model consisting of TNM classification and tumor grade, which also achieved favorable clinical net benefit, with a threshold probability in the range of 0 to 42%. The nomogram consisting of TNM classification and tumor grading was shown to have better performance for predicting cancer-specific mortality in penile cancer patients who underwent definitive surgery. Our data support the integration of this model in decision-making and trial design.

Abstract
Dysregulation of long noncoding RNAs (lncRNAs) has been regarded as a primary feature of several human cancers. However, the genome-wide expression and functional significance of lncRNAs in bladder cancer remains unclear. The aim of this study was to identify aberrantly expressed lncRNAs that may play an important role in contributing to bladder cancer pathogenesis. In this study, we described lncRNAs profiles in four pairs of human bladder cancer and matched normal bladder tissues by microarray. We finally determined 3,324 differentially expressed human lncRNAs and 2,120 differentially expressed mRNAs (≥2-fold change). A total of 110 lncRNAs were significantly differentially expressed between the tumor and the control groups (≥8-fold change). Four lncRNAs (TNXA, CTA-134P22.2, CTC-276P9.1 and KRT19P3) were selected for further confirmation of microarray results using quantitative PCR (qPCR), and a strong correlation was identified between the qPCR results and microarray data. We also observed that numerous lncRNA expression levels were significantly correlated with the expression of tens of protein coding genes by construction of the lncRNA-mRNA co-expression network. Kyoto Encyclopedia of Genes and Genomes annotation showed a significant association with p53, bladder cancer, cell cycle and propanoate metabolism pathway gene expression in the bladder cancer group compared with the normal tissue group, indicating that deregulated lncRNAs may act by regulating protein-coding genes in these pathways. We demonstrated the expression profiles of human lncRNAs in bladder cancer by microarray. We identified a collection of aberrantly expressed lncRNAs in bladder cancer compared with matched normal tissue. It is likely that these deregulated lncRNAs play a key or partial role in the development and/or progression of bladder cancer.

Abstract
Objective To investigate the behavior of Chinese erectile dysfunction (ED) patients after radical prostatectomy (RP) who were offered the penile rehabilitation and to assess their attitude and feasibility of rehabilitation after RP in China. Materials and methods Comprehensive medical and sexual histories of 187 evaluable PCa patients for RP were obtained together with their attitude towards penile rehabilitation. The rehabilitation data was compared between patients who accepted this treatment or not. The successful intercourse rate six months after treatment was also compared among three rehabilitation interventions, including phosphodiesterase type 5 inhibitor (PDE-5i), vacuum erection device (VED) and combination of both. Results 141 (75.4%) patients reported being sexually active in the six months before RP.122 (65.2%) patients wished to preserve sexual activity and 80 (42.8%) had interest in penile rehabilitation after RP. Penile rehabilitation rate was 30.5%. The patients with younger age (P<0.001), higher IIEF-5 score preoperatively (P=0.03) and no adjuvant therapy post-RP (P=0.01) were more acceptable for rehabilitation. Main reasons for refusal of rehabilitation included lack of sexual interest followed by high cost of treatment. The successful intercourse rate was not significantly different among three rehabilitation interventions (P=0.32). Conclusions Less than one-third of Chinese RP patients accepted penile rehabilitation postoperatively. Patients’ attitude towards rehabilitation was conservative because of many reasons from traditional Chinese culture, doctors and patients themselves. Penile rehabilitation was feasible and effective in Chinese RP patients.

Abstract
OBJECTIVE To assess the efficacy and safety of the Osbon ErecAid Vacuum Therapy System in the treatment of erectile dysfunction (ED) that fails to respond to PDE-5i. METHODS This study included 70 cases of ED not responding to the medication of PDE-5i. The patients were aged 25 -66 (38.9 +/- 9.1) years. Under our direction, the patients used the Osbon ErecAid Vacuum Therapy System for a month to increase blood oxygenation to the corpora cavernosa, and then employed the vacuum constriction device (VCD) to maintain penile erection for sexual intercourse. We compared their IIEF-5 scores and their and their partners' sexual satisfaction before and 3 months after treatment, and evaluated the safety and effect of the vacuum therapy. RESULTS The mean IIEF-5 scores of the patients were significantly increased from 10.2 +/- 4.0 before treatment to 13.3 +/- 4.7 at 3 months after the vacuum therapy (P < 0.05). The rate of therapeutic effectiveness was 77.1% (54/70), and the rates of sexual satisfaction of the patients and their partners were 64.3% (45/70) and 65.7% (46/70), CONCLUSION Vacuum therapy for ED that does not respond to PDE-5i can significantly improve the patients' erectile function as well as their and their partners'sexual satisfaction, and therefore deserves clinical application.

Abstract
The aim of the present study was to investigate the effects of Pseudomonas aeruginosa-mannose-sensitive hemagglutinin (PA-MSHA) on inhibiting the proliferation of bladder cancer cell lines and to further define its functional mechanisms. T24 and 5637 cells were treated with PA-MSHA at various concentrations and times. Cell proliferation was analyzed using Cell Counting Kit-8 (CCK-8) assays. The cell cycle distribution and apoptosis induced by PA-MSHA were measured by flow cytometry with propidium iodide (PI) and annexin V-fluorescein isothiocyanate (FITC) staining. Western blotting was used to evaluate the expression levels of the apoptosis-related molecules and PI3K-AKT-mTOR signaling pathway proteins. A time- and concentration-dependent cytotoxic effect of PA-MSHA was observed in the T24 and 5637 cells. Flow cytometry with PI and annexin V-FITC staining showed that the various concentrations of PA-MSHA were all able to induce the apoptosis and G0-G1 cell cycle arrest of the bladder cancer cells. Cleaved caspase-8 and -9 and Fas protein expression levels were markedly associated with an increase in the apoptosis of the bladder cancer cells. The cells stimulated with PA-MSHA also exhibited a downregulation of PI3K-AKT-mTOR signaling. PA-MSHA inhibits proliferation and induces apoptosis in the T24 and 5637 bladder cancer cell lines by modulating caspase family proteins and affecting the cell cycle regulation machinery. The PI3K-AKT-mTOR signaling pathway may be important in the direct anticancer cytotoxic effect of PA-MSHA.

Abstract
Killer cell immunoglobulin-like receptor (KIR) and human leucocyte antigen (HLA) play crucial role in maintaining immune homoeostasis and controlling immune responses. To investigate the influence of KIR and HLA-C ligands on the risk of pulmonary tuberculosis (PTB), we studied 200 patients who were confirmed to have PTB and 200 healthy controls on the different frequencies of KIR and HLA-C ligands. Genotyping of these genes was conducted by sequence-specific primer polymerase chain reaction (SSP-PCR) method. Gene frequencies were compared between PTB group and the control group by χ(2) test, and P < 0.05 was regarded as statistically significant. As a result, the frequency of KIR genotype A/B was increased in PTB than controls but A/A was decreased. Moreover, striking differences were observed in the frequencies of HLA-Cw*08 between the two groups. Besides, the frequencies of '2DL2/3 with C1' in PTB were increased compared with control group. In addition, individuals with no KIR2DS3 and no Cw*08 were higher in controls than in PTB. KIR2DS1 was increased in PTB when HLA-C group 2 alleles were missing. In conclusion, KIR and HLA-C gene polymorphisms were related to susceptibility to PTB.

Abstract
PURPOSE Accurate assessment of disease characteristics is a prerequisite for treatment decision making regarding small renal masses. In this study we evaluate the association between visceral obesity and Fuhrman grade in patients with cT1a renal cell carcinoma. MATERIALS AND METHODS We retrospectively collected data on 186 patients with surgically treated cT1a renal cell carcinoma. Single slice computerized tomography was used to measure the area of visceral and subcutaneous adipose tissue. Visceral obesity was calculated as the proportion of visceral adipose tissue to overall adipose tissue. Other analyzed factors included clinical characteristics (age, gender, body mass index and tumor size) and anatomical features of the tumor defined by the R.E.N.A.L. nephrometry score. The association between predictors and high grade disease (Fuhrman grade III or IV) were assessed using logistic regression analyses. RESULTS A total of 47 (25.3%) tumors were classified as high grade. The percentage of visceral adipose tissue was higher in male participants but did not correlate with body mass index, age or tumor size. In univariate analyses the percentage of visceral adipose tissue and tumor size were significantly associated with higher Fuhrman grade. Multivariate analysis showed that the percentage of visceral adipose tissue (OR 1.06, p = 0.0018) and tumor size (OR 1.91, p = 0.047) were independent predictors of high grade cancer. Addition of the percentage of visceral adipose tissue to a model including clinical characteristics and anatomical features of the tumor remarkably improved its discriminatory ability (p = 0.0010). CONCLUSIONS Increased visceral obesity was found to be strongly associated with higher Fuhrman grade in patients with cT1a renal cell carcinoma. Further studies are needed to confirm these findings and discover the underlying biological mechanism.

Abstract
After severe thermal injury, hypertrophic scarring which is associated with accumulation of extracellular matrix proteins including fibronectin, frequently develops. We have recently demonstrated that interferon alfa-2b significantly reduces the level of type 1 procollagen messenger RNA expressed by both hypertrophic and normal dermal fibroblasts. In this report, we provide evidence that this cytokine also significantly decreases the expression of fibronectin messenger RNA in human hypertrophic scar and normal dermal fibroblasts. Four dermal fibroblast cell strains were established in cell culture from four human postburn hypertrophic scar tissues with the use of normal dermal fibroblasts from the same patients as controls. These cells were then treated with 2000 U/ml interferon alfa-2b in culture medium at various times. The results of Northern analysis of interferon-treated dermal fibroblasts indicate that this cytokine reduced the expression of fibronectin messenger RNA as early as 12 hours after treatment and reached its lowest level (24% relative to untreated fibroblasts) after 96 hours. When the expression of fibronectin messenger RNA was quantified by densitometry for each individual paired cell strain, a differential response to interferon treatment was found among cell strains. The level of fibronectin messenger RNA expression decreased from 17.2% to 69% in hypertrophic scar fibroblasts and 47% to 83.7% in normal fibroblasts relative to that of untreated control values. Although this decrease was less pronounced in normal fibroblasts than in hypertrophic scar fibroblasts, this reduction was significant in both interferon alfa-2b treated hypertrophic scar fibroblasts (6.39 +/- 0.71 versus 2.88 +/- 0.9, n = 4, p < 0.05) and normal cells compared with untreated controls (5.47 +/- 0.89 versus 3.64 +/- 0.99, n = 4, p < 0.05) as assessed with Student's paired t test. Rehybridization of the RNA blot prepared from interferon alfa-2b treated and untreated hypertrophic scar fibroblasts with a complementary DNA for the tissue inhibitor of metalloproteinase type 2 gelatinase inhibitor showed no significant changes in abundance of this transcript. This result suggests that this cytokine selectively suppresses the expression of fibronectin messenger RNA and that this reduction is not due to RNA loading. A dot blot analysis of total RNA extracted from these tissues was carried out to compare the expression of fibronectin messenger RNA between human hypertrophic scar tissues and normal dermis obtained from the same patients. The blot was initially hybridized with fibronectin complementary DNA and subsequently with a complementary DNA for the tissue inhibitor of metalloproteinase type 2 to correct for RNA loading. When the ratio of fibronectin to tissue inhibitor or metalloproteinase type 2 messenger RNA expression for each hypertrophic scar tissue was compared with its normal control, this ratio was fourfold higher in human hypertrophic scar tissues relative to normal controls. In contrast, the expression of this message in cultured hypertrophic scar fibroblasts was not significantly different from that in normal fibroblasts. The results of this study suggest that hypertrophic scarring developing after thermal injury is associated with an overexpression of fibronectin messenger RNA, and interferon alfa-2b may be of therapeutic value to down-regulate the expression of this transcript.

Abstract
OBJECTIVE To investigate the efficacy and safety of vacuum erection device (VED) for erectile dysfunction (ED) after radical prostatectomy (RP). METHODS Six cases of ED after open RP were reviewed. Three of the patients started a daily rehabilitation protocol using VED 10 min/d within 3 months after RP (group A, early intervention), while the other 3 initiated the same protocol after 12 months (group B, late intervention). We compared the IIEF-5 scores as well as stretched penile lengths and mid-shaft circumferences before and after 3 and 6 months of VED rehabilitation. We also assessed the safety of the device and sexual satisfaction of the patients and their partners. RESULTS The mean IIEF-5 score of the six cases was remarkably increased at 3 and 6 months of VED rehabilitation (P < 0.05), significantly higher in group A than in B at 3 months (8.7 +/- 0.6 vs 6.7 +/- 0.6, P < 0.05) and 6 months (13.0 +/- 1.0 vs 8.3 +/- 1.5, P < 0.05). After 6 months of VED rehabilitation, there were no significant changes in stretched penile length or mid-shaft circumference in group A, both significantly decreased in group B (P < 0.05), and sexual satisfaction of the patients and their partners were 83.3% and 50%, respectively. No serious adverse events were observed except mild complaint of pe- nile skin darkening in 1 case and numb feeling during the intercourse in 2. CONCLUSION Early use of VED after RP improves erectile function and helps to preserve the length and mid-shaft circumference of the penis.

Abstract
We demonstrated a 1.91 μm pumped, injection-seeded Q-switched Ho:YAG laser operating at room temperature. By inserting two Fabry-Perot etalons into the laser cavity, single-frequency Tm, Ho:YAG seed lasing was achieved at a wavelength of 2090.9 nm, with a typical output power of 60 mW. Single-frequency, nearly transform-limited Q-switched operation of the Ho:YAG laser was achieved by injection seeding. The output energy of the single-frequency Q-switched pulse is 7.6 mJ, with a pulse width of 132 ns and a repetition rate of 100 Hz. We measured the pulse spectrum, half-width of which was 3.5 MHz, by a heterodyne technique.

Abstract
Several prediction models have been developed to estimate the outcomes of prostate biopsies. Most of these tools were designed for use with Western populations and have not been validated across different ethnic groups. Therefore, we evaluated the predictive value of the Prostate Cancer Prevention Trial (PCPT) and the European Randomized Study of Screening for Prostate Cancer (ERSPC) risk calculators in a Chinese cohort. Clinicopathological information was obtained from 495 Chinese men who had undergone extended prostate biopsies between January 2009 and March 2011. The estimated probabilities of prostate cancer and high-grade disease (Gleason >6) were calculated using the PCPT and ERSPC risk calculators. Overall measures, discrimination, calibration and clinical usefulness were assessed for the model evaluation. Of these patients, 28.7% were diagnosed with prostate cancer and 19.4% had high-grade disease. Compared to the PCPT model and the prostate-specific antigen (PSA) threshold of 4 ng ml(-1), the ERSPC risk calculator exhibited better discriminative ability for predicting positive biopsies and high-grade disease (the area under the curve was 0.831 and 0.852, respectively, P<0.01 for both). Decision curve analysis also suggested the favourable clinical utility of the ERSPC calculator in the validation dataset. Both prediction models demonstrated miscalibration: the risk of prostate cancer and high-grade disease was overestimated by approximately 20% for a wide range of predicted probabilities. In conclusion, the ERSPC risk calculator outperformed both the PCPT model and the PSA threshold of 4 ng ml(-1) in predicting prostate cancer and high-grade disease in Chinese patients. However, the prediction tools derived from Western men significantly overestimated the probability of prostate cancer and high-grade disease compared to the outcomes of biopsies in a Chinese cohort.

Abstract
It has been suggested that pancreatic cancer is associated with a greater prevalence of depression than many other cancers, but the mechanism accounting for this potential association has not yet been illustrated. In the present study, conditioned media (CM) from three pancreatic cancer cell lines and primary pancreatic cancer cells from two patients were added to culture system of differentiated pheochromocytoma cell line PC12. The release of dopamine (DA) and norepinephrine (NE) by PC12 was significantly inhibited after CM treatment (P < 0.05), similar to what happened after recombinant interleukin 6(IL-6) treatment. Furthermore, pretreatment with anti-IL-6 antibody significantly blocked the inhibitory effects of pancreatic cancer CM on DA and NE production (P < 0.05). We also demonstrated that tyrosine hydroxylase (TH), the rate-limiting enzyme for synthesis of catecholamine, was reduced after exposure to IL-6, which was accompanied by JAK-STAT3 pathway activation. Our results demonstrated that IL-6 in CM from pancreatic cancer down-regulated the production of DA and NE by PC12 cell. The possible underlying mechanisms might be decreasing TH production via activation of JAK-STAT3 signal transduction pathway. The present study might help to better understand the close relationship between pancreatic cancer and depression.

Abstract
PURPOSE We developed a nomogram to predict the duration of drainage in patients with penile cancer treated with inguinal lymph node dissection. MATERIALS AND METHODS A total of 111 groin basins in 56 patients who underwent radical inguinal lymph node dissection for penile cancer were retrospectively assessed. We retrieved the clinicopathological factors from the medical records including age, body mass index, albumin, smoking history, hypertension, diabetes, preoperative radiotherapy/chemotherapy, palpable lymph nodes, previous lymph node biopsy, total number of resected lymph nodes and ratio of positive lymph nodes. The criterion of drain removal was total drain output of 50 ml or less per day for 2 days starting from postoperative day 3. A multivariate Cox proportional hazards model was used to explore the risk factors of drainage duration and variable selection was performed according to Akaike's information criteria. A nomogram was built based on regression coefficients and internally validated with 200 bootstrap resamples. RESULTS Median postoperative drainage duration was 7 days. The prediction model using pretreatment factors showed a concordance index of 0.55. With the addition of lymph node related variables a second model was constructed which produced a better concordance index (0.65) and good calibration. On multivariate analysis young age, high body mass index, total number of resected lymph nodes and ratio of positive lymph nodes were independent predictors of prolonged lymphatic drainage. CONCLUSIONS On the basis of readily obtained clinicopathological variables we developed a nomogram to predict the duration of lymphatic drainage which, if externally validated, could be helpful for patient consultation, treatment decision making and clinical trial design.

Abstract
OBJECTIVES To determine whether carbonic anhydrase IX (CA IX) has prognostic value of lymph node metastases and cancer-specific survival in penile squamous cell carcinoma treated with surgery. MATERIALS AND METHODS CA IX expression was detected in the primary disease of 73 penile cancer patients using the method of immunohistochemistry. The expression levels of CA IX were categorized into 2 groups according to the cutoff of 10% of positively stained tumor cells. Associations between CA IX expression and clinicopathologic characteristics, immunoreactivity of p53 and Ki-67, and outcomes were analyzed. RESULTS High CA IX expression was observed in 31 (42.5%) of cases. CA IX expression was not associated with patient age, T stage, grade, lymphovascular invasion, and Ki-67 expression, but was associated with p53 expression (P = 0.015). Both univariate and multivariate analysis failed to show CA IX expression was a statistically significant predictor of lymph node metastases and cancer-specific survival. CONCLUSIONS Immunohistochemical expression of CA IX did not associate with lymph node metastases and cancer-specific survival in penile squamous cell carcinoma. A panel of prognostic markers that reflect the characteristic of tumor cell and organ microenvironment may be more suitable for prognostication in penile cancer.
