Abstract
INTRODUCTION Emphysematous epididymo-orchitis is a rare cause of acute scrotum pain characterized by gas formation within the tissue. Diabetes mellitus and recto-seminal fistula secondary to sigmoid diverticulitis are generally accepted as being responsible for this disease. However, prostate invasion secondary to rectal cancer may be considered to be a newly identified pathogenetic mechanism. Herein, we report this rare case and illustrate the pathogenesis. CASE PRESENTATION A 69-year-old man arrived at our emergency department presenting with sepsis and acute scrotal pain. Emphysematous epididymo-orchitis was diagnosed by scrotal sonography initially; however, advanced rectal cancer with prostate invasion was diagnosed by CT after a recurrent episode. An exploratory laparotomy with abdominoperineal resection and radical prostectomy were performed after neoadjuvant chemoradiotherapy. Histopathologic analysis confirmed the previous diagnosis. Emphysematous epididymo-orchitis caused by advanced rectal cancer is very rare, and our case is the first to be reported according to a literature search. Neoadjuvant chemoradiotherapy plus extended surgery can achieve a good oncological outcome. CONCLUSION This case indicated that the very rare presentation as emphysematous epididymo-orchitis caused by locally advanced colorectal cancer.

Abstract
Immunotherapy using bacille Calmette-Guerin (BCG) instillation is the mainstay treatment modality for superficial urothelial cancer (UC) through toll-like receptor (TLR) activation of cognitive immune response. We investigated the roles of TLR7 in the activation of apoptosis in UC cells after BCG treatment. The in vitro cytotoxicity effect of BCG on UC cells was measured by a modified 3-(4,5-dimethylthiazo-2-yl)-2,5-diphenyl tetrazolium assay. Expressions of TLR7 mRNA and protein in native UC cells prior to and after BCG treatment were analyzed using real-time quantitative polymerase chain reaction and western blot methods. Phagocytotic processes after BCG treatment in UC cells were observed microscopically using a specific immunostain, subsequent cellular apoptosis-related signals induced by TLR7 were analyzed by western blot. Low-grade UC cells, TSGH8301, showed significant cellular death (4.23-fold higher than the high-grade UC cells T24 and J82) when treated with BCG and the BCG cytotoxicity was displayed in a dose-time-dependent manner. TSGH8301 cells had the highest content of TLR7 mRNA, 7.2- and 4.5-fold higher than that of T24 and J82 cells, respectively. TLR7 protein expression was also significantly increased in TSGH8301 cells. Phagocytosis-related markers, including beclin 1, ATG2, and LC3, were increased when TSGH8301 cells were treated by BCG. Interleukin-1 receptor-associated kinases 2 and 4 were also increased markedly in TSGH8301 cells. On the contrary, cellular apoptosis of TSGH8301 cells decreased by 34% when TLR7 activation was suppressed by the TLR antagonist IRS661 after BCG treatment. Our findings suggest that well differentiated TCC cells have higher expression of TLR7 and BCG can drive cellular death of TCC cells directly via TLR7 activation and related apoptotic pathway.

Abstract
BACKGROUND To assess the impacts of age, performance status, and clinical stage on advanced urothelial carcinoma of the bladder (UCB) in patients treated with different treatment modalities. METHODS This retrospective study included 160 patients who underwent radical cystectomy (RC) with/without neoadjuvant or adjuvant chemoradiotherapy, palliative chemotherapy/radiotherapy/chemoradiotherapy (CRT), and transurethral resection of bladder tumor (TURBT) monotherapy for advanced UCB in one institution from 2000 to 2010. Kaplan-Meier analysis was used to calculate the survival distributions of overall survival (OS). The quality of life of the patients was also analyzed. RESULTS The median age of the patients was 74.0 years, and the mean survival interval was 31.5 months. The 2-year OS was significantly different among the three modalities [RC > TURBT monotherapy, odds ratio (OR): 1.86, 95% CI: 1.17-2.96, p = 0.009; CRT > TURBT monotherapy, OR: 1.65, 95% CI: 1.06-2.57, p = 0.026]. There were no significant differences in the 5- and 10-year OS rates between the three treatment modalities. Those younger than 76 years receiving RC had a significantly better 2-year OS than those undergoing CRT and TURBT monotherapy (RC > TURBT monotherapy, OR: 2.38; 95% CI: 1.30-4.33, p = 0.005). The number and duration of re-hospitalizations were highest in the CRT group and lowest in the TURBT group. CONCLUSION The short- and long-term OS rates of the three modalities were similar in those older than 76 years. Therefore, patients younger than age 76 years are likely to have a better outcome undergoing radical cystectomy for advanced UCB.

Abstract
The polycomb group gene, EZH2, is highly expressed in advanced bladder cancer. Here we demonstrated that down-regulation of EZH2 in tumor tissues after neo-adjuvant chemotherapy correlated with good therapeutic response in advanced bladder cancer. We next developed a small molecule, NSC745885, derived from natural anthraquinone emodin, which down-regulated EZH2 via proteasome-mediated degradation. NSC745885 showed potent selective toxicity against multiple cancer cell lines but not normal cells. NSC745885 treatment overcame multiple-drug resistance and inhibited growth of resistant cancer cells. Over-expression of EZH2 in cancer cells attenuated effects of NSC745885, suggesting that down-regulation of EZH2 was responsible for growth inhibition of NSC745885. NSC745885 also suppressed tumor growth and down-regulated EZH2 in vivo. These results indicate that NSC7455889 suppresses bladder cancer by targeting EZH2.

Abstract
Mitochondria are the powerhouses of cells. Mitochondrial C-Raf is a potential cancer therapeutic target, as it regulates mitochondrial function and is localized to the mitochondria by its N-terminal domain. However, Raf inhibitor monotherapy can induce S338 phosphorylation of C-Raf (pC-Raf(S338)) and impede therapy. This study identified the interaction of C-Raf with S308 phosphorylated DAPK (pDAPK(S308)), which together became colocalized in the mitochondria to facilitate mitochondrial remodeling. Combined use of the Raf inhibitors sorafenib and GW5074 had synergistic anticancer effects in vitro and in vivo, but targeted mitochondrial function, rather than the canonical Raf signaling pathway. C-Raf depletion in knockout MEF(C-Raf-/-) or siRNA knockdown ACHN renal cancer cells abrogated the cytotoxicity of combination therapy. Crystal structure simulation showed that GW5074 bound to C-Raf and induced a C-Raf conformational change that enhanced sorafenib-binding affinity. In the presence of pDAPK(S308), this drug-target interaction compromised the mitochondrial targeting effect of the N-terminal domain of C-Raf, which induced two-hit damages to cancer cells. First, combination therapy facilitated pC-Raf(S338) and pDAPK(S308) translocation from mitochondria to cytoplasm, leading to mitochondrial dysfunction and reactive oxygen species (ROS) generation. Second, ROS facilitated PP2A-mediated dephosphorylation of pDAPK(S308) to DAPK. PP2A then dissociated from the C-Raf-DAPK complex and induced profound cancer cell death. Increased pDAPK(S308) modification was also observed in renal cancer tissues, which correlated with poor disease-free survival and poor overall survival in renal cancer patients. Besides mediating the anticancer effect, pDAPK(S308) may serve as a predictive biomarker for Raf inhibitors combination therapy, suggesting an ideal preclinical model that is worthy of clinical translation.

Abstract
The purpose of this study is to build a cost-effective and easy-to-popularize laparoscopic training system based on improving traditional training box. The system has the capability of objective skills assessment and the function of automatic recording of training process and results, as well as 3-dimensional coordinate tracking of instruments. The results of pilot experiment in laparoscopic-assisted grip skill assessment had been shown the system can assess the different grip ability level between the senior surgeons and junior residents. Regarding to the evaluation of training effectiveness, five subjects without laparoscopic surgery experiences were asked to perform grip training for five days to observe their training curves. According to the experimental results, the total time taken for subject 1 to subject 5 are improved by 54.9%, 52.0%, 60.6%, 23.3%, and 63.5% separately.
