Abstract
OBJECTIVE To investigate the safety and feasibility of using a novel purpose-built single-port robotic system (the SHURUI Robotic Surgical System) with deformable surgical instruments to perform retroperitoneal single-port partial nephrectomy. MATERIALS AND METHODS A prospective study was conducted to recruit patients with a single renal tumor no more than 4 cm. Robot-assisted single-port partial nephrectomy was performed by using the novel purpose-built single-port robotic system with deformable surgical instruments. Patients' demographics, tumor characteristics, and perioperative parameters were recorded and analyzed. RESULTS Sixteen patients were recruited to the study. The median tumor size was 2.0 cm (IQR: 1.2-2.4 cm). The median R.E.N.A.L score was 6 (IQR: 4-4.5). In 3 cases, pure single-port surgery was carried out, and all the assistance was through the robotic port. Median docking time was 15.5 min (IQR: 14.25-22.25 min). Median operating time was 148.5 min (IQR: 178-238.5 min). Median console time was 107 min (IQR: 92.75-149.75 min). Median warm ischemic time was 26.5 min (IQR: 24.5-30 min). Median blood loss was 17.5 ml (IQR: 10-50 ml). CONCLUSIONS Retroperitoneal partial nephrectomy can be safely performed with this novel purpose-built single-port robotic system (SHURUI) with deformable surgical instruments. Further studies are needed to fully evaluate the role of this new platform.

Abstract
BACKGROUND Further stratification of the risk of recurrence of clear-cell renal cell carcinoma (ccRCC) with venous tumor thrombus (VTT) will facilitate selection of candidates for adjuvant therapy. OBJECTIVE To assess the impact of tumor grade discrepancy (GD) between the primary tumor (PT) and VTT in nonmetastatic ccRCC on disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS). DESIGN, SETTING, AND PARTICIPANTS This was a retrospective analysis of a multi-institutional nationwide data set for patients with pT3N0M0 ccRCC who underwent radical nephrectomy and thrombectomy. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS Pathology slides were centrally reviewed. GD, a bidirectional variable (upgrading or downgrading), was numerically defined as the VTT grade minus the PT grade. Multivariable models were built to predict DFS, OS, and CSS. RESULTS AND LIMITATIONS We analyzed data for 604 patients with median follow-up of 42 mo (excluding events). Tumor GD between VTT and PT was observed for 47% (285/604) of the patients and was an independent risk factor with incremental value in predicting the outcomes of interest (all p < 0.05). Incorporation of tumor GD significantly improved the performance of the ECOG-ACRIN 2805 (ASSURE) model. A GD-based model (PT grade, GD, pT stage, PT sarcomatoid features, fat invasion, and VTT consistency) had a c index of 0.72 for DFS. The hazard ratios were 8.0 for GD = +2 (p < 0.001), 1.9 for GD = +1 (p < 0.001), 0.57 for GD = -1 (p = 0.001), and 0.22 for GD = -2 (p = 0.003) versus GD = 0 as the reference. According to model-converted risk scores, DFS, OS, and CSS significantly differed between subgroups with low, intermediate, and high risk (all p < 0.001). CONCLUSIONS Routine reporting of VTT upgrading or downgrading in relation to the PT and use of our GD-based nomograms can facilitate more informed treatment decisions by tailoring strategies to an individual patient's risk of progression. PATIENT SUMMARY We developed a tool to improve patient counseling and guide decision-making on other therapies in addition to surgery for patients with the clear-cell type of kidney cancer and tumor invasion of a vein.

Abstract
Bisphenol A (BPA), as an environmental endocrine disruptor can cause damage to the reproductive, nervous and immune systems. Laccase can be used to degrade BPA. However, laccase is easily deactivated, especially in organic solvents, but the specific details are not clear. Molecular dynamics simulations were used to investigate the reasons for changes in laccase activity in acetonitrile (ACN) and dimethyl formamide (DMF) solutions. In addition, the effects of ACN and DMF on the activity of laccase and surfactant rhamnolipid (RL) on the degradation of BPA by laccase were investigated. Results showed that addition of ACN changed the structure of the laccase, not only decreasing the van der Waals interaction that promoted the binding of laccase with BPA, but also increasing the polar solvation free energy that hindered the binding of laccase with BPA, so it weakened the laccase activity. DMF greatly enhanced the van der Waals interaction between laccase and BPA, and played a positive role in their binding. The addition of surfactant RL alleviated the effect of organic solvent on the activity of laccase by changing the polar solvation energy. The mechanism of surfactant RL affecting laccase activity in ACN and DMF is described, providing support for understanding the effect of organic solvents on laccase.

Abstract
Purpose: The aim of this study was to explore the safety and efficacy of radical prostatectomy with a novel Shurui single-port (SR-SP) robotic surgical system. Methods: A total of 11 patients with prostate cancer were enrolled in this study. Extraperitoneal radical prostatectomy was performed using the SR-SP robotic surgical system for all patients. Clinicopathologic data, perioperative data, and short-term surgical outcomes were prospectively collected and analyzed. Results: Of the 11 patients, the median age was 65 years (range 52-73), and the median body mass index was 22.6 kg/m2 (range 20.2-26.7). The median operative time was 229 minutes (range 194-317), and the median console time was 167 minutes (range 141-265). The median blood loss was 40 mL (range 10-120), and none of the patients required intraoperative transfusion. There was no conversion to open surgery during the operation, and no assistant ports were added. The surgeons reported a good task load rating with a National Aeronautics and Space Administration Task Load Index (NASA-TLX) score of 25.1 ± 3.3 points. The median postoperative hospital stay time was 7 days (range 4-15). There were no severe intraoperative or postoperative complications (Clavien grade ≥3). Postoperative positive surgical margin occurred in 4 (36.4%) patients. No biochemical recurrence occurred within 1 month of surgery. The continence rate was 72.7% (8/11) 1 month after surgery. Conclusions: The new SR-SP robotic surgical system is safe, effective, flexible, and stable for application in radical prostatectomy.

Abstract
There is significant variability with respect to the prognosis of nonmetastatic clear cell renal cell carcinoma (ccRCC) patients with venous tumor thrombus (VTT). By applying multiregion whole-exome sequencing on normal-tumor-thrombus-metastasis quadruples from 33 ccRCC patients, we showed that metastases were mainly seeded by VTT (81.8%) rather than primary tumors (PTs). A total of 706 nonmetastatic ccRCC patients with VTT from three independent cohorts were included in this study. C-index analysis revealed that pathological grading of VTT outperformed other indicators in risk assessment (OS: 0.663 versus 0.501-0.610, 0.667 versus 0.544-0.651, and 0.719 versus 0.511-0.700 for Training, China-Validation, and Poland-Validation cohorts, respectively). We constructed a risk predicting model, TT-GPS score, based on four independent variables: VTT height, VTT grading, perinephric fat invasion, and sarcomatoid differentiation in PT. The TT-GPS score displayed better discriminatory ability (OS, c-index: 0.706-0.840, AUC: 0.788-0.874; DFS, c-index: 0.691-0.717, AUC: 0.771-0.789) than previously reported models in risk assessment. In conclusion, we identified for the first-time pathological grading of VTT as an unheeded prognostic factor. By incorporating VTT grading, the TT-GPS score is a promising prognostic tool in predicting the survival of nonmetastatic ccRCC patients with VTT.

Abstract
PURPOSE To explore the preliminary safety and efficacy of the Shurui single-port surgical robot in partial nephrectomy. METHODS This study prospectively enrolled patients with T1a renal tumours who met the inclusion criteria from February to July 2022 in The First Affiliated Hospital School of Medicine Zhejiang University. The operative outcomes and perioperative data, including clinical and histological data, were prospectively collected and analysed. RESULTS A total of 13 patients were included in this study, including 7 males and 6 females. The median age was 53 (33-74) years, and the average body mass index was 24.9±4.2 kg/m2. There were 6 cases of left kidney tumours and 7 cases of right kidney tumours in the 13 patients. The average tumour diameter was 1.9±0.9 cm. In all operations, the diseased tissue was removed according to the established surgical plan. The average warm ischaemia time was 26.2±9.7 minutes; the average device docking time was 3.6±1.8 minutes; and the average robotic arm operation time was 124.7±40.4 minutes. All operations were successfully completed; there was no conversion to open surgery during the operation; and no operation holes were added. The NASA-TLX score was 26.3±2.6 points, and no device-related adverse events occurred during the operation. The median time to discharge was 6 days (range, 4-11 days). Postoperative pathological examination showed that all tumour margins were negative. There were no Clavien grade ≥3 surgical complications in any of the patients during the perioperative period or at the 1-month postoperative follow-up. CONCLUSION The new single-port surgical robot system is safe, effective, flexible, and stable for application in partial nephrectomy.

Abstract
Background Diabetes mellitus-induced erectile dysfunction (DMED) is a frequent complication of diabetes mellitus (DM), with limited therapy at present. This study aimed to explore the role and mechanism of Ganoderma lucidum polysaccharide (GLP) on DMED. Methods DMED was induced in the experimental rats [male 12-week-old Sprague-Dawley (SD) rats] by treatment with streptozotocin (60 mg/kg) and apomorphine (APO). Next, rats in the GLP low dose (GLP-L)/GLP high dose (GLP-H) groups were treated with GLP (100 or 400 mg/kg/d, respectively) for 8 weeks. Subsequently, erectile function was assessed by APO and electrostimulation of the cavernous nerve (CN). Serum or penile testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH), and cyclic guanosine monophosphate (cGMP) contents were evaluated by enzyme-linked immunosorbent assay (ELISA). The levels of oxidative stress indicators in the corpus cavernosum (CC) were measured by corresponding kits, and histological changes in the CC were observed by hematoxylin-eosin (HE) and Masson staining. Additionally, the apoptosis index, caspase-3, caspase-9, and eNOS expression, and mitochondrial membrane potential (MMP) were also detected. Furthermore, quantitative polymerase chain reaction (qPCR) and western blot assays were conducted to determine the NOS, TGF-β1 mRNA expression, ERK1/2, eNOS, JNK phosphorylation, and arginase II protein expression. Results The erectile function test revealed that erectile dysfunction (ED) was alleviated in the DMED rats following treatment with GLP. Moreover, GLP upregulated the T and cGMP content, improved the oxidative stress and histological injuries of CC, and also inhibited the apoptosis and MMP loss of penile tissues in DMED rats. Furthermore, GLP treatment enhanced the mRNA expression of NOS and TGF-β1 and suppressed the phosphorylation of ERK1/2, eNOS, and JNK, as well as the protein expression of arginase II in DMED rats. Conclusions GLP ameliorated DMED by repairing the CC pathological damage and upregulating NOS expression and ERK/JNK phosphorylation, indicating that GLP may be a candidate drug for DMED therapy.

Abstract
OBJECTIVE To investigate the effects of persistent Echinococcus multilocularis infections on hepatic fibrosis in mice, so as to provide insights into the understanding of liver fibrogenesis induced by E. multilocularis infections and the treatment of alveolar echinococcosis. METHODS Hepatic stellate HSC-T6 and LX-2 cells were exposed to the sera (25, 50 and 100 μL) from Meriones unguiculatus infected with E. multilocularis, and E. multilocularis, germinal layer cells (GCs) and protoscoleces (PSCs) for 48 hours, respectively. The cell proliferation was measured using a CCK-8 assay, and the levels of collagen 1 (Col1) and α-smooth muscle actin (α-SMA) were measured in the culture supernatant of HSC-T6 cells using ELISA. In addition, the serum and liver samples were collected 1, 2, 4, 6, 8 months post-infection with E. multilocularis, respectively. The serum Col1 and α-SMA concentrations were measured using enzyme-linked immunosorbent assay (ELISA), and the deposition of collagen fibers was examined in mice livers using Sirius red staining. RESULTS The sera of E. multilocularis-infected gerbils promoted the proliferation of HSC-T6 and LX-2 cells in vitro, and there were significant differences seen in the proliferative rate of HSC-T6 (FHSC-T6 = 126.50, P < 0.05) and LX-2 cells (FLX-2 = 201.50, P < 0.05) among different serum groups, with the highest proliferative rate of HSC-T6 (573.36% ± 206.34%) and LX-2 cells (940.38% ± 61.65%) found following exposure to 100 μL mouse sera. Exposure to serum from E. multilocularis-infected gerbils resulted in an increase in the Col1 and α-SMA levels in the culture supernatant of HSC-T6 cells, with the greatest Col1 (20.99 ng/mL ± 2.01 ng/mL) and α-SMA levels (305.52 pg/mL ± 16.67 pg/mL) measured following exposure to 100 μL sera. The metacestodes (142.65% ± 9.17% and 189.99% ± 7.75%), GCs (118.55% ± 8.96% and 122.54% ± 0.21%) and PSCs of E. multilocularis (156.34% ± 17.45% and 160.59% ± 31.41%) all promoted the proliferation of HSC-T6 and LX-2 cells in vitro, and there were significant differences in the proliferative rates of HSC-T6 (FHSC-T6 = 11.24, P < 0.05) and LX-2 cells among groups (FLX-2 = 47.72, P < 0.05). Exposure to E. multilocularis resulted in an increase in Col1 and α-SMA levels in the culture supernatant of HSC-T6 cells, and the highest Col1 (4.43 ng/mL ± 2.23 ng/mL) and α-SMA levels (285.20 pg/mL ± 90.67 pg/mL) were detected following treatment with E. multilocularis metacestodes. In addition, a persistent increase was seen in the deposition of collagen fibers in mice livers 1 to 8 months post-infection with E. multilocularis, with the greatest Col1 level (280.26 ng/mL ± 23.04 ng/mL) seen 6 months post-infection and the highest α-SMA level (33.68 ng/mL ± 4.45 ng/mL) detected 8 months post-infection, respectively. CONCLUSIONS Persistent E. multilocularis infections promote hepatic stellate cell proliferation, induce an increase in mouse serum Col1 and α-SMA levels, and cause elevated deposition of collagen fibers in mice livers. The infective stage of E. multilocularis is a critical period for inducing hepatic fibrosis of alveolar echinococcosis.

Abstract
INTRODUCTION Neurogenic tumors are the most frequent neoplasms of the lower posterior mediastinum. Traditionally, lower posterior mediastinal tumors are excised by video-assisted thoracic surgery. However, the available robotic treatment for the lower posterior mediastinum tumors to date are rare. Herein, we report a case of a right lower posterior mediastinal tumors successfully treated with retroperitoneal robot-assisted surgery using a transdiaphragmatic approach. PATIENT CONCERNS A 54-year-old male patient without any symptoms was admitted into our department with a right lower posterior mediastinal paravertebral tumor that was detected during a medical check-up. DIAGNOSIS A right lower posterior mediastinal paravertebral tumor. INTERVENTIONS Retroperitoneal robot-assisted resection using a transdiaphragmatic approach was performed. OUTCOMES The patient was treated with retroperitoneal robot-assisted surgery using a transdiaphragmatic approach and remained disease-free throughout a 6-month follow-up. His postoperative course was uneventful. Histopathological examination revealed a benign schwannoma. CONCLUSION Our initial experience showed that retroperitoneal robot-assisted resection of a lower posterior mediastinal tumor using a transdiaphragmatic approach is technically feasible and can be considered a potential alternative for either video-assisted thoracic surgery or a thoracotomy.

Abstract
Background: Surgical management of complicated retroperitoneal mass is one of the most challenging urologic oncologic surgeries. This study aims to describe our technique and experience in dealing with retroperitoneal mass. Methods: Three patients with complicated retroperitoneal mass were treated with robot-assisted surgery with four arms through retroperitoneal approach. Surgical Procedure: Our standardized anatomic-based "kidney safe first, then mass resection" technique for robot-assisted complicated retroperitoneal mass resection focused on minimizing the chance of renal pedicle injury. Baseline demographics, pathology data, and latest follow-up outcome were obtained. Results: In this retrospectively reviewed case series, all 3 patients were successfully treated with robot-assisted surgery with four arms during retroperitoneal space. One patient received paravertebral mass resection 2 weeks after the robotic surgery. Mean data included operative time of 175 minutes, estimated blood loss was 133 mL, and hospital stay was 4 days. No complications occurred. Conclusions: Robot-assist surgery for complicated retroperitoneal mass with four arms is a safe and feasible way. Patient Summary: Mini-invasive treatment for retroperitoneal mass with robotic four arms through retroperitoneal approach is a feasible way. The approach reduces interruption of intracorporeal structure and organs. And patients could benefit from the retroperitoneal approach with a quicker recovery.

Abstract
OBJECTIVE To evaluate the possibility and efficiency of a modified margin strategy in laparoscopic partial nephrectomy with selective renal artery clamping. METHODS Seventy-six cases of laparoscopic partial nephrectomy with segmental renal artery clamping in Shanghai Changhai Hospital between July 2014 and September 2017 were retrospectively reviewed. Relevant clinical data were recorded including baseline patient and tumor characteristics, and surgical outcomes (segmental artery mobilization time, operating time, warm ischemic time, estimated blood loss, complications, and so on). A comparative analysis between standard technique and margin strategy was performed. RESULTS In 38 cases, margin strategy to mobilize segmental artery was successfully performed. In the other 38 cases, the surgery was performed in traditional method. The use of new strategy led to a shortened segmental artery mobilization time (5 min vs 12 min, p < 0.001). There was no difference in terms of perioperative complications between the two techniques. CONCLUSIONS The margin strategy is a practical method in laparoscopic partial nephrectomy with selective renal artery clamping. It provides a simplified way of finding segmental arteries. Further studies are needed to confirm these preliminary findings.

Abstract
Background: To report our experience with retroperitoneal robot-assisted laparoscopic upper pole heminephrectomy in adult patients with duplex kidneys. Methods: We retrospectively reviewed the medical records of 7 patients who underwent retroperitoneal robot-assisted laparoscopic upper pole heminephrectomy at our institution between September 2014 and July 2017. Of the robot-assisted laparoscopic procedures, 5 were on the left and 2 on the right side. Results: All patients underwent robot-assisted laparoscopic surgery successfully in a totally retroperitoneal manner without conversion to open surgery. The mean operative time was 175 mins (range 140-270). The mean estimated blood loss was 84 mL (range 20-200). The mean postoperative hospital stay was 7 days (range 5-9). No major intraoperative and postoperative complications occurred. All patients had a resolution of their presenting symptoms after surgery at a mean follow-up of 24 months (range 14-38). Conclusion: Our initial clinical experience suggests that robot-assisted laparoscopic upper pole heminephrectomy using a retroperitoneal approach for a duplex kidney appears to be safe with acceptable perioperative outcomes.

Abstract
BACKGROUND Recently, the effects of hydroxytyrosol on autophagy during acute lung injury (ALI) have drawn increasing attention. OBJECTIVE We explored the underlying molecular mechanisms by which hydroxytyrosol exerts its anti-inflammatory effects in a murine model of ALI by up-regulating autophagy. METHODS Male BALB/c mice, challenged with intranasal instillations of LPS, were treated with or without hydroxytyrosol (HT, 100 mg/kg, intragastrically) 1 h prior to LPS exposure. Twenty-four hours later, lung and bronchoalveolar lavage (BAL) fluid samples were obtained for the determination of lung wet to dry weight (W/D) ratios, protein leakage levels, and differential counts of inflammatory cells in BAL fluid. LPS-induced cytokine activity, inflammatory factor levels, sirtuin (SIRT1/3/6) expression, mitogenactivated protein kinase (MAPK) activation, and autophagy marker expression in ALImice were examined by western blotting and staining methods. Molecular docking between HT and SIRT and MAPK was studied with a Sybyl/Surflex module. RESULTS LPS-stimulated SIRT inhibition, MAPK phosphorylation, and autophagy suppression were all notably abolished by HT administration. HT treatment significantly attenuated pulmonary edema and inflammatory cell infiltration into lung tissues, accompanied by decreased lung W/D ratios, protein concentrations, and inflammatory cell levels in BAL fluid. LPS driven release of inflammatory mediators, including TNF-α, IL-1β, IL-6, IL-10, and MCP-1, was strongly regulated by HT. CONCLUSIONS The protective effect of HT on lung inflammation in ALI mice may be attributed to the promotion of autophagy, which is likely associated with the activation of the SIRT/MAPK signaling pathway. Importantly, this study provides new insight into the molecular mechanisms of HT and its therapeutic potential in the treatment of acute respiratory distress syndrome.

Abstract
OBJECTIVE To investigate the effect of add-on exenatide to insulin on glycemic excursion and the counter-regulatory hormone in response to hypoglycemia in patients with type 1 diabetes mellitus (T1DM). METHODS 30 patients with T1DM were recruited and randomly assigned to exenatide + insulin-treated group (group 1, n = 15) or insulin-only-treated group (group 2, n = 15) for 4 weeks. All patients had continuous glucose monitor system (CGMS) applied at before (week-0) and after (week-4) treatment to evaluate the glycemic variability. All patients had an arginine-stimulated test at before and after treatment. Six patients from each group also had hypoglycemic clamp test to assess counter-regulatory hormone level. RESULTS Patients in the exenatide group had significant reductions in body weight, body mass index (BMI), total insulin dose, bolus insulin dose, fructosamine, and glycemic excursion after 4 weeks' treatment. Compared with patients in group 2, the mean amplitude of glycemic excursion (MAGE) and coefficient of variation (CV) of exenatide group decreased significantly. Similarly, a significant decrease of glucagon (GLC) in the arginine-stimulated test was found in group 1. No significant changes of GLC, growth hormone (GH), cortisol (COR), epinephrine (E), and norepinephrine (NE) were found in both groups during hypoglycemia clamp test. However, patients who had residual islet function in group 1 showed an upward trend of basic C-peptide (C-P) and GLC during the hypoglycemia period. CONCLUSION Although exenatide could inhibit glucagon secretion during euglycemia or hyperglycemia in patients with T1DM, it has no effect on GLC and counter-regulatory hormones during hypoglycemia clamp in patients with no functional residual islet test.

Abstract
AIM To determine the clinical non-inferiority of recombinant glargine-Basalin vs glargine-Lantus, in treatment of type 2 diabetes mellitus (T2DM) using continuous glucose monitoring system (CGMS). METHODS One hundred patients with T2DM were recruited. They were either regularly taking Basalin (Basalin group) or Lantus (Lantus group) (n = 50 each). CGMS was employed to real-time monitor blood glucose profile for 4 days (from day 1 to day 5). To exclude the effect of patient background, the study design was to have a blinded crossover from glargine-Basalin to glargine-Lantus on day 3, and vice versa. 24-hour mean blood glucose (24hMBG), 24-hour standard deviation of blood glucose (24hSDBG), 24-hour mean amplitude of glycemic excursion (24hMAGE), and number of glycemic excursion (NGE) every 24 h (24hNGE) were calculated for each glargine from 100 patients. RESULTS No significant difference of 24hMBG, 24hSDBG, 24hMAGE, and 24hNGE (p > 0.05 for all) was found between Basalin and Lantus treatments. The glucose area under the curve and time when blood glucose was below 3.9 mmol/L, between 3.9 and 10.0 mmol/L, or above 10.0 mmol/L were similar between Basalin and Lantus treatment. The frequency of hypoglycemic episodes was also similar. However, the mean cost of Basalin was only 72% of Lantus's in one treatment course. CONCLUSION Glargine-Basalin is non-inferior in clinical efficacy compared to glargine-Lantus. In view of the large difference in the cost of glargine-Basalin, it would be much more cost-effective for our patients.

Abstract
RATIONALE Typically robot-assisted laparoscopic retroperitoneal lymph node dissection (R-RPLND) has been performed via a transperitoneal approach. Herein we report the first case of a novel R-RPLND using an extraperitoneal approach. PATIENT CONCERNS A 38-year-old man presented with an enlarging right scrotal mass. DIAGNOSES Scrotal ultrasonography demonstrated a 5.5-cm solid mass of the right testis. The patient underwent right radical inguinal orchiectomy. Pathologic examination demonstrated a mixed germ cell tumor, predominately embryonal carcinoma with yolk sac tumor. INTERVENTIONS Extraperitoneal R-PRLND was performed 3 weeks after the radical orchiectomy. OUTCOME The final pathologic examination showed a count of 19 lymph nodes, all of them negative. Normal antegrade ejaculation returned within 4 weeks postoperatively. No retroperitoneal recurrence or elevation of tumor marker levels were seen via surveillance imaging. LESSONS Our study shows that extraperitoneal R-RPLND is a safe and feasible procedure using an extraperitoneal approach that provides minimal invasion and rapid recovery of patients.

Abstract
Iron is essential for rapidly dividing spermatocytes during normal mammalian spermatogenesis. Decreased transferrin and transferrin receptor levels were observed in seminal plasma from idiopathic azoospermia (IA) patients, suggesting disturbed iron metabolism in IA testes. However, how Sertoli cells (SCs) contribute to the iron homoeostasis in IA is still unclear. In this study, we analysed 30 IA and 30 age-matched obstructive azoospermia (OA) patients undergoing testicular sperm aspiration (TESA). SCs hyperplasia was indicated by higher SC density and Ki-67 labelling index in the IA TESA specimens. The attenuated expression of superoxide dismutase (SOD) suggested an impaired antioxidative capacity in IA testes. We further detected increased levels of iron importer divalent metal transporter 1 with iron responsive element (DMT1 + IRE) in IA testes, whereas the increasing trend of iron exporter ferroportin 1 (FPN1) was not statistically significant. Next, we demonstrated that iron regulatory protein 1 (IRP1) and hypoxia-inducible factor-1α (HIF-1α), which can potentially bind to the IRE and hypoxia-responsive element in the DMT1 + IRE mRNA, were both up-regulated in IA testes. Unexpectedly, HIF-2α was down-regulated in IA testes. These results indicate that there is a dysregulation of DMT1 + IRE in IA testes, which might due to the up-regulation of IRP1 and HIF-1α.

Abstract
OBJECTIVE Estramustine, an agent with both hormonal and non-hormonal effects in men, is supposed to be effective in treating castration-resistant prostate cancer. However, previous studies have reported conflicting results. We conducted this meta-analysis to evaluate the efficacy and toxicity of additional estramustine to chemotherapy. METHODS Data sources including PubMed, Medline, EMBASE, and Cochrane Controlled Trials Register were searched to identify potentially relevant randomized controlled trials. Prostate specific antigen (PSA) response, overall survival, and grade 3 to 4 toxicity were analyzed. RESULTS Seven randomized controlled trials, a total of 839 patients, were enrolled. The pooled odds ratio for PSA response was 3.02 (95% CI=1.69-5.39, P=.0002); the pooled hazard ratio for overall survival was .95 (95% CI=.80-1.14, P=.58); the pooled odds ratio for nausea/vomiting and cardiovascular toxicity were 3.90 (95% CI=1.05-14.45, P=.04) and 2.22 (95% CI=1.15-4.30, P=.02). No significant difference was detected for neutropenia, anemia, thrombocytopenia, diarrhea, fatigue, or neuropathy (P>.05). CONCLUSIONS According to this meta-analysis, chemotherapy with additional estramustine increased the PSA response rate. However, it increased the risk of grade 3 or 4 adverse effects such as nausea/vomiting and cardiovascular events, and the overall survival was not improved for castration-resistant prostate cancer patients.

Abstract
ABSTRACTWe measured the equivalent noise charge of a-Si:H pin diodes (5 ∼ 45 μm i-layer) with a pulse shaping time of 2.5 μ.sec under reverse biases up to 30 V/μm and analyzed it as a four component noise source. The frequency spectra of 1/f noise in the soft-breakdown region and of the Nyquist noise from contact resistance of diodes were measured. Using the conversion equations for a CR-RC shaper, we identified the contact resistance noise and the 1/f noise as the main noise sources in the low bias and high bias regions respectively. The 1/f noise of a-Si:H TFTs with channel length of 15 μm was measured to be the dominant component up to ∼100kHz for both saturation and linear regions.

Abstract
To facilitate the wider use of genetic resources including newly collected cultivated and wild azuki bean germplasm, the genetic diversity of the azuki bean complex, based on 13 simple sequence repeat (SSR) primers, was evaluated and a core collection was developed using 616 accessions originating from 8 Asian countries. Wild germplasm from Japan was highly diverse and represented much of the allelic variation found in cultivated germplasm. The SSR results together with recent archaeobotanical evidence support the view that Japan is one center of domestication of azuki bean, at least for the northeast Asian azuki bean. Cultivated azuki beans from China, Korea, and Japan were the most diverse and were genetically distinct from each other, suggesting a long and relatively isolated history of cultivation in each country. Cultivated azuki beans from eastern Nepal and Bhutan were similar to each other and quite distinct from others. For two primers, most eastern Nepalese and Bhutanese cultivated accessions had null alleles. In addition, wild accessions from the Yangtze River region of China and the Himalayan region had a null allele for one or the other of these primers. Whether the distinct diversity of azuki bean in the Himalayan region is due to introgression or separate domestication events requires further study. In contrast, western Nepalese azuki beans showed an SSR profile similar to that of Chinese azuki beans. The genetic distinctness of cultivated azuki beans from Vietnam has been revealed for the first time. The specific alleles indicate that Vietnamese azuki beans have been cultivated in isolation from Chinese azuki beans for a long time. Wild germplasm from the Himalayan region showed the highest level of variation. Based on the results, Himalayan germplasm could be considered a novel gene source for azuki bean breeding. A comparison with mungbean SSR analysis revealed that the mean gene diversity of cultivated azuki bean (0.74) was much higher than that of cultivated mungbean (0.41). The reduction in gene diversity due to domestication, the domestication bottleneck, in azuki bean is not strong compared with that in mungbean.

Abstract
Sex hormones are strongly associated with bone mineral density (BMD) in adult humans. Leptin, a hormonal product of the OB gene, also appears to be associated with BMD, but results from previous studies are conflicting. Most of the studies in this area have been in women and apparently none have simultaneously analyzed the relationship of estradiol, testosterone, and leptin with BMD in healthy men. To address these issues, serum sex hormones, sex-hormone-binding globulin (SHBG), leptin, dehydroepiandrosterone sulfate (DHEAS), and insulin were measured in 50 apparently healthy men, 18-66 years of age. After controlling for age and body mass index (BMI), BMD correlated positively with estradiol ( p=0.007) and testosterone ( p=0.019), but negatively with leptin ( p=0.001). No significant correlations between BMD and SHBG, DHEAS, or insulin were observed. In multiple regression analysis with age, BMI, estradiol, testosterone, and leptin as the independent variables, only age ( p<0.05), BMI ( p<0.001), and leptin ( p=0.004) were significantly related to BMD. These findings suggest that in men, leptin may have an important negative relationship with BMD.

Abstract
Overexpression of the receptor tyrosine kinase p185ErbB2 confers Taxol resistance in breast cancers. Here, we investigated the underlying mechanisms and found that overexpression of p185ErbB2 inhibits Taxol-induced apoptosis. Taxol activates p34Cdc2 kinase in MDA-MB-435 breast cancer cells, leading to cell cycle arrest at the G2/M phase and, subsequently, apoptosis. A chemical inhibitor of p34Cdc2 and a dominant-negative mutant of p34Cdc2 blocked Taxol-induced apoptosis in these cells. Overexpression of p185ErbB2 in MDA-MB-435 cells by transfection transcriptionally upregulates p21Cip1, which associates with p34Cdc2, inhibits Taxol-mediated p34Cdc2 activation, delays cell entrance to G2/M phase, and thereby inhibits Taxol-induced apoptosis. In p21Cip1 antisense-transfected MDA-MB-435 cells or in p21-/- MEF cells, p185ErbB2 was unable to inhibit Taxol-induced apoptosis. Therefore, p21Cip1 participates in the regulation of a G2/M checkpoint that contributes to resistance to Taxol-induced apoptosis in p185ErbB2-overexpressing breast cancer cells.

Abstract
We recently found that overexpression of p185c-erbB2 in c-erbB2 transfected MDA-MB-435 breast cancer cells (435.eB transfectants) confers a 5-9-fold increase in Taxol resistance. To examine whether Taxol resistance is a common phenomenon in other c-erbB2 overexpressing breast cancer cell lines, we tested a panel of human breast cancer cell lines established from different patients and expressing pl85c-erbB2 at different levels for their sensitivity to Taxol and Taxotere, a synthetic taxoid. Higher expression of p185c-erbB2 in these breast cancer cell lines indeed correlated well with resistance to Taxol and Taxotere, and the degree of resistance was about 100-fold that in c-erbB2-overexpressing 435.eB transfectants, demonstrating that these breast cancer cells are highly resistant to Taxol. Since mdr-1-encoded p-glycoprotein (p170mdr-1) has been implicated in Taxol resistance, we next examined the p170mdr-1 levels in these breast cancer cell lines that are highly resistant to Taxol. Higher levels of p170mdr-1 expression were found in several breast cancer cell lines that are highly resistant to Taxol. Since these same breast cancer cell lines also expressed higher levels of p185c-erbB2, we sought to determine the relative contribution of p185c-erbB2 and p170mdr-1 overexpression to Taxol resistance. We first specifically down-regulated cell surface p185c-erbB2 using anti-p185c-erbB2 monoclonal antibodies and assayed sensitivity of these cells to Taxol. We next specifically inactivated p170mdr-1 function using p170mdr-1 blockers (thioridazine or verapamil) and again assayed Taxol sensitivity. Both p185c-erbB2 down-regulation and p170mdr-1 blockade significantly sensitized the breast cancer cell lines to Taxol. The results indicate that overexpression of either p185c-erbB2 or p170mdr-1 renders human breast cancer cells resistant to Taxol. Furthermore, p185c-erbB2 synergizes with p170mdr-1 conferring higher degrees of Taxol resistance. Finally, combination therapy (down-regulation of p185c-erbB2 plus blocking p170mdr-1 plus administration of Taxol) may be beneficial to breast cancer patients whose tumors express high levels of both p185c-erbB2 and p170mdr-1.
