Abstract
Objective: To analyze and compare the risk factors for hemorrhagic stroke and ischemic stroke and understand the exposure levels in population. Methods: A cohort study of risk factors of stroke was conducted in a rural community in Fengxian District of Shanghai in 2003, and the common risk factors of stroke were investigated at baseline survey, the cerebrovascular hemodynamics indexes were detected, the cerebrovascular function score was calculated according to the unified integral rule, and the incidence of stroke was observed in follow up. The risk factors for hemorrhagic stroke and ischemic stroke were analyzed by cohort study. The risk factors for two subtypes of stroke were compared. Result: A total of 10 565 participants were included in the study, with a mean follow-up period of (11.15±2.26) years, and 103 hemorrhagic stroke cases and 268 ischemic stroke cases were observed during follow-up period. The independent risk factors of hemorrhagic stroke included decreased cerebrovascular function score [hazard ratio (HR)=1.56, 95%CI: 1.23-1.98], history of alcohol consumption (HR=2.46, 95%CI: 1.39-4.34), hypertension (HR=1.75, 95%CI: 1.00-3.07) and older age (HR=1.07, 95%CI: 1.04-1.10). The independent risk factors of ischemic stroke included decreased cerebrovascular function score (HR=1.43, 95%CI: 1.25-1.65), smoking history (HR=1.52, 95%CI: 1.13-2.05), hypertension (HR=1.51, 95%CI: 1.10-2.07), family history of stroke (HR=1.89, 95%CI: 1.13-3.15), left ventricular hypertrophy (HR=1.74, 95%CI: 1.07-2.81) and older age (HR=1.07, 95%CI: 1.05-1.08). Conclusions: Decreased cerebrovascular function score, hypertension, and older age were common independent risk factors of both types of stroke, alcohol consumption history was an independent risk factor of hemorrhagic stroke, and smoking history, and family history of stroke and left ventricular hypertrophy were independent risk factors of ischemic stroke.

Abstract
Objective: To investigate the clinical efficacy and safety of 125I seed implantation in the treatment of mediastinal lymph node metastasis of lung cancer. Methods: Clinical data of 36 patients who underwent CT-guided 125I seed implantation for mediastinal lymph node metastasis of lung cancer from August 2013 to April 2020 in three hospitals of the Northern radioactive particle implantation treatment collaboration group were retrospectively collected, including 24 males and 12 females, aged 46 to 84 years. Cox regression model was used to analyze the relationship between local control rate, survival rate and tumor stage, pathological type, postoperative D90, postoperative D100 and other variables, and to analyze the occurrence of complications. Results: The objective response rate of CT-guided 125I seed implantation in the treatment of mediastinal lymph node metastasis of lung cancer was 75% (27/36), the median control time was 12 months, the 1-year local control rate was 47.2% (17/36), and the median survival time was 17 months. The 1-year and 2-year survival rates were 61.1% (22/36) and 22.2% (8/36) respectively. Univariate analysis showed that in the treatment of mediastinal lymph node metastasis with CT-guided 125I implantation, factors related to local control included tumor stage (HR=5.246, 95%CI: 2.243-12.268, P<0.001), postoperative D90 (HR=0.191, 95%CI: 0.085-0.431, P<0.001), postoperative D100 (HR=0.240, 95%CI: 0.108-0.533, P<0.001); The factors affecting survival were tumor stage (HR=2.712, 95%CI: 1.356-5.425, P=0.005), postoperative D90 (HR=0.110, 95%CI: 0.041-0.294, P<0.001), postoperative D100 (HR=0.212, 95%CI: 0.092-0.489, P<0.001). Multivariate analysis showed that tumor stage (HR=5.305, 95%CI: 2.187-12.872, P<0.001) and postoperative D100 (HR=0.237, 95%CI: 0.099-0.568, P<0.001) were correlated with local control rate. Tumor stage (HR=2.347, 95%CI: 1.095-5.032, P=0.028) and postoperative D90 (HR=0.144, 95%CI: 0.051-0.410, P<0.001) were correlated with survival. In terms of complications, 9 of the 36 patients had pneumothorax, and 1 of them was cured by closed thoracic drainage for severe pneumothorax; 5 cases developed pulmonary hemorrhage and 5 cases developed hemoptysis, which recovered after hemostasis treatment. One case developed pulmonary infection and recovered after anti-inflammatory treatment. No radiation esophagitis and radiation pneumonia occurred; No grade 3 or higher complications occurred. Conclusion: 125I seed implantation in the treatment of lung cancer mediastinal lymph node metastasis has a high local control rate and controllable adverse effects.

Abstract
OBJECTIVES The Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 classified chronic obstructive pulmonary disease (COPD) patients into more and less symptomatic groups. This study aimed to analyze the clinical characteristics, risk of future exacerbation and mortality among patients in more symptomatic group. DESIGN A retrospective cohort study. SETTING Data were obtained from patients enrolled in a database setup by Second Xiangya Hospital of Central South University. PARTICIPANTS 1729 stable COPD patients listed from September 2017 to December 2019 in the database. The patients were classified into more and less symptomatic groups based on GOLD 2017 report. OUTCOMES All patients were followed up for 18 months. We collected baseline data and recorded the number of exacerbations and mortality during follow-up. RESULTS The more symptomatic patients were older, had higher Clinical COPD Questionnaire (CCQ) scores, more severe airflow limitation and higher number of exacerbations and hospitalizations in the past year (P < 0.05). Logistic regression showed that having more symptoms correlated with the CCQ scores and exacerbations in the past year (P < 0.05). After patients were followed up, there were higher numbers of exacerbations, hospitalizations and mortality rates in more symptomatic patients (P < 0.05). The multivariate model showed that age more than 65 years (OR = 2.047, 95% CI = 1.020-4.107) and COPD assessment test scores more than 30 (OR = 2.609, 95% CI = 1.339-5.085) were independent risk factors for mortality, whereas current smoker (OR = 1.565, 95% CI = 1.052-2.328), modified Medical Research Council scores (OR = 1.274, 95% CI = 1.073-1.512) and exacerbations in the past year (OR = 1.061, 95% CI = 1.013-1.112) were independent risk factors for exacerbation in more symptomatic patients (P < 0.05). CONCLUSIONS More symptomatic COPD patients have worse outcomes. In addition, several independent risk factors for exacerbation and mortality were identified. Therefore, clinicians should be aware of these risk factors and take them into account during interventions.

Abstract
Objective: To examine the significance and prognostic value of the classification of hilar cholangiocarcinoma based on actual anatomical location. Methods: A retrospective study was conducted including 120 patients of hilar cholangiocarcinoma treated at the Second Affiliated Hospital,Zhejiang University School of Medicine and Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2019 to December 2021. Patients with hilar cholangiocarcinoma were classified for seven types according to the site of tumor location. The clinicopathological and prognostic data of 120 patients were retrospectively analyzed(There were 57 males and 63 females,the age (M(IQR)) was 61(22)years(range:42 to 85 years)). All patients received radical resection without visible intraoperative tumor residue and negative bile duct resection margin according to intraoperative pathological biopsy. The classification variables were analyzed by Pearson χ2 test or Fisher's exact probability test,one-way ANOVA or Kruskal-Wallis rank sum test.Kaplan-Meier method was used for survival analysis. Cox proportional risk model was used for prognostic factors. Results: The coincidence rate of preoperative surgical planning and actual operational styles was verified in 33 cases. Twenty-six cases were consistent,and 7 cases were inconsistent,with a coincidence rate of 78.8%. According to the actual anatomical location,patients in type of secondary branch experienced a significantly longer operation duration,a higher portal vein resection rate,margin positive rate and more advanced T stage(all P<0.05). The median overall survival time of the unilateral main trunck group was 27.0 months,and the bilateral group was 17.0 months. Survival analysis based on the tumor classification of the actual anatomical location showed that the unilateral or main trunck group predicted less aggressive clinical features and favorable outcomes(HR=1.931,95%CI:1.066 to 3.499,P<0.05). Multivariate analysis demonstrated that the actual anatomical location of the tumor type(HR=2.269,95%CI:1.333 to 3.861,P=0.003),combined liver resection(HR=0.464,95%CI:0.253 to 0.848,P=0.013) and N stage(HR=6.317,95%CI:3.083 to 12.944,P<0.01) were independent factors affecting the prognosis of patients. Conclusion: The classification based on the actual anatomy can be used as a promising scheme in refining patient stratification and predicting survival in hilar cholangiocarcinoma,and it can guide the selection of surgical methods,and predict operative safety and radical resection rate.

Abstract
Objective: To explore the application of Endo-GIA stapler in laparoscopic radical cystectomy, especially in the treatment of lateral bladder ligament, and to evaluate its clinical feasibility and practicability. Methods: A retrospective analysis of clinical data about 38 cases of laparoscopic radical cystectomy (LRC) treated in the Department of Urology, Chaoyang Hospital of Beijing and Cancer Hospital, Chinese Academy of Medical Sciences from July 2017 to June 2019 were conducted. The patients were divided into Endo-GIA stopler group(18 cases) and non-Endo-GIA stopler group (20 cases) according to whether Endo-GIA stapler were used. The basic clinical data, operation time of bladder lateral ligament, operation time of bladder lateral wall, operation time of bladder resection, amount of bleeding during operation, pathological data after operation and related indicators of recovery after operation were compared between the two groups. Results: All 38 patients underwent radical cystectomy (RC) successfully under 3-D laparoscopy without conversion to open surgery. The operation time of bladder lateral ligament in Endo-GIA stapler group was significantly shorter than that in non-Endo-GIA stapler group [(3.25±0.75) min vs (9.20±2.95) min, P=0.042]; the operation time of bladder lateral wall in Endo-GIA stapler group was significantly shorter than that in non-Endo-GIA stapler group [(8.06±1.66) min vs (14.30±3.37) min, P=0.016]. The operation time of cystectomy in the Endo-GIA stapler group was significantly shorter than that in the non-Endo-GIA stapler group [(47.06±4.70) min vs (61.60±14.91) min,P=0.003]. The amount of bleeding in the Endo-GIA stapler group was significantly shorter than that in the non-Endo-GIA stapler group [(37.77±21.30) ml vs (114.50±39.80) ml, P=0.015]. The time of drainage tube removal in Endo-GIA group was significantly shorter than that in the non-Endo-GIA group [(5.83±1.54) d vs (7.30±3.00) d, P=0.002]. The length of post-hospitalization in Endo-GIA group was significantly shorter than that in the non-Endo-GIA group [(7.67±1.78) d vs (9.60±3.25) d,P=0.036]. However, there was no significant difference in other basic clinical data, post-operative pathology and post-operative recovery related indicators. Conclusions: Laparoscopic radical cystectomy using Endo-GIA stapler device is safe and feasible. It is easy to operate, shorten the operation time significantly, and reduce the amount of bleeding. To a certain extent, it is conducive to the recovery of patients after operation to some extent, and worthy of clinical application.

Abstract
AIMS Trimethylamine N-oxide (TMAO), choline and betaine serum levels have been associated with metabolic diseases including type 2 diabetes (T2D) and non-alcoholic fatty liver disease (NAFLD). These associations could be mediated by insulin resistance. However, the relationships among these metabolites, insulin resistance and NAFLD have not been thoroughly investigated. Moreover, it has recently been suggested that TMAO could play a role in NAFLD by altering bile acid metabolism. We examined the association between circulating TMAO, choline and betaine levels and NAFLD in obese subjects. METHODS Serum TMAO, choline, betaine and bile acid levels were measured in 357 Mexican obese patients with different grades of NAFLD as determined by liver histology. Associations of NAFLD with TMAO, choline and betaine levels were tested. Moreover, association of TMAO levels with non-alcoholic steatohepatitis (NASH) was tested separately in patients with and without T2D. RESULTS TMAO and choline levels were significantly associated with NAFLD histologic features and NASH risk. While increased serum TMAO levels were significantly associated with NASH in patients with T2D, in non-T2D subjects this association lost significance after adjusting for sex, BMI and HOMA2-IR. Moreover, circulating secondary bile acids were associated both with increased TMAO levels and NASH. CONCLUSIONS In obese patients, circulating TMAO levels were associated with NASH mainly in the presence of T2D. Functional studies are required to evaluate the role of insulin resistance and T2D in this association, both highly prevalent in NASH patients.

Abstract
Objective: To analyze the metabolism of blood glucose and lipid in breast cancer patients after the first chemotherapy. Methods: Breast cancer patients who received chemotherapy for the first time from December 2016 to January 2020 were collected in our hospital, and their blood glucose and lipid levels were monitored. Patients were grouped according to different treatment plans. Non-parametric rank sum test was used for statistical analysis on SPSS software. Results: There were 1 356 female breast cancer patients were enrolled, blood glucose and lipid levels were compared before and after chemotherapy. Our results showed that baseline medium blood glucose was 5.2 mmol/L, lower than 5.3 mmol/L after chemotherapy (P<0.05). The baseline triglyceride (TG) was 1.2 mmol/L, lower than 1.6 mmol/L after chemotherapy (P<0.05). The baseline small dense low-density lipoprotein (sdLDL) was 0.7 mmol/L, lower than 0.8 mmol/L after chemotherapy (P<0.05). The baseline high density lipoprotein (HDL) was 1.3 mmol/L, higher than 1.2 mmol/L after chemotherapy (P<0.05). Patients' menstrual status and body mass index were related with blood glucose, TG, LDL and sdLDL (all P< 0.05). Conclusions: Abnormal metabolism of blood glucose and lipid are observed in breast cancer patients after the first chemotherapy. More awareness of cardiovascular disease in breast cancer patients might ensure their overall clinical benefits.

Abstract
Objective: To analyze the correlative factors of sigmoid sinus diverticulum(SSD) formation in individuals without pulsatile tinnitus based on computed tomography angiography (CTA). Methods: A hospital-based 1∶2 matched case-control study was performed on 42 cases with unilateral SSD and 84 controls for age, gender, and side-matched in Beijing Friendship Hospital affiliated to the Capital Medical University from January 2018 to December 2018.The signs including sigmoid sinus wall dehiscence, venous outflow dominance, transverse sinus stenosis, high jugular bulb, large emissary veins, degree of mastoid pneumatization (grade Ⅰ-Ⅳ) and empty sella, were detected and analyzed. Results: In SSD group and control group, there were statistically significant differences in the incidence of the sigmoid sinus wall dehiscence (66.7%(28/42) vs 19.0%(16/84)), ipsilateral transverse sinus stenosis on the dominant side of venous outflow (26.2%(11/42) vs 4.8%(4/84)), and empty sellae (19.0%(8/42) vs 7.1%(6/84))(all P<0.05).The degree of mastoid pneumatization was worse in SSD group (P<0.05). After stepwise logistic regression analysis,the sigmoid sinus wall dehiscence (P<0.01,OR=6.794,95%CI 2.530-18.245), ipsilateral transverse sinus stenosis on the dominant side (P=0.001, OR=13.293, 95%CI 2.841-62.194), and degree of mastoid pneumatization (P<0.01, OR=0.289, 95%CI 0.156-0.536) were found independently correlated with SSD. Conclusion: Sigmoid sinus wall dehiscence, ipsilateral transverse sinus stenosis on the dominant side of venous outflow and mastoid pneumatization may be some of the independent correlative factors of SSD.

Abstract
AIM To report the initial experiences with functional cine magnetic resonance urography (cine MRU) and assess its usefulness as a novel postoperative evaluation method of ileal ureter substitution. MATERIALS AND METHODS The medical records of 17 patients from who underwent cine MRU during June 2010 to December 2019 during their follow-up after ileal ureter substitution were collected. The cine MRU videos of reconstructive urinary tract were observed, and the luminal diameter, contraction ratio, peristaltic waves, and ureteral jets were measured. RESULTS Seventeen patients underwent cine MRU after ileal ureter substitution during their follow-up. Based on their cine MRU videos assessing the morphology and the peristaltic motility of the reconstructive urinary tract, there was resolution of preoperative hydronephrosis, which matched their ameliorative renal function. Clearly, peristaltic motility of the ileal graft was observed in 14 patients with obvious peristaltic waves and ureteral jets. CONCLUSION This study is the first to assess the clinical utility of functional cine MRU during the patient follow-up after ileal ureter substitution. Cine MRU is a radiation-free, non-invasive imaging method that can clearly show the morphology and the peristaltic motility of the ileal graft. Therefore, cine MRU, as a novel technique, will be extremely useful in the postoperative evaluation of patients after ileal ureter substitution.

Abstract
Summary In recent years, the cartilage tissue engineering technology has rapid development, and shows a bright prospect in the field of cartilage defect and repair. In this paper, the field of rhinology cartilage tissue engineering research progress were reviewed, with the purpose to understand the status quo, and determine the next step research direction. From the research in recent years, we found that although cartilage tissue engineering technique could play an important role in the field of rhinology, but the progress to date was still lagging behind. In the published literature, there were few basic and applied research about cartilage tissue engineering techniques for nasal diseases. There have a small amount of applied research report, mainly concentrated in the animal experiments. There are still quite a distance from a wide range of clinical application. Based on the existing research results, cartilage tissue engineering technique in nasal plastic and reconstruction surgery has great potential in clinic application and needs more further research.

Abstract
OBJECTIVE To evaluate the feasibility and effectiveness of the totally extraperitoneal renal autotransplantation with boari flap-pelvis anastomosis in the treatment of upper urinary tract urothelial carcinoma (UTUC), and to review the experience of renal autotransplantation for UTUC treatment. METHODS One case of applying the totally extraperitoneal renal autotransplantation with boari flap-pelvis anastomosis to the UTUC treatment was reported, and related literature was reviewed. The patient was a sixty-four-year old man who received right radical nephroureterectomy for right ureteral carcinoma 1 year before and diagnosed as left ureteral carcinoma(G2, high grade) this time. In order to preserve his renal function and avoid the shortness of common kidney-sparing surgery, a totally extraperitoneal procedure, including retroperitoneoscopic nephrectomy, ureterectomy, renal autotransplantation and Boari flap-pelvis anastomosis, was performed to the patient. RESULTS The operation was completed successfully without perioperative complications. The renal function recovered to preoperative level within 1 week. No deterioration of renal function during the follow-up and no tumor recurrence was observed under cystoscopy at the 3-month postoperative consult. CONCLUSION The totally extraperitoneal renal autotransplantation with Boari flap-pelvis anastomosis is a feasible and effective treatment for UTUC. The innovative procedure has several advantages compared to the former ones. The extraperitoneal procedure results in significantly less pain, shorter hospital stay, decreased overall time to recovery and lower bowel complications risk without warm ischemia time extension. Meanwhile, the Boari flap-pelvis anastomosis simplifies the follow -up protocols and creates an easy route for cystoscopy and topical therapy. From the systematic clinical analysis, as well as the related literature review, it's been concluded that the renal autotransplantation can be a reasonable option for the patients who have UTUC in solitary kidney or have bilateral UTUC. This type of treatment possesses advantages of preservation of renal function and total resection of malignant lesions. But long-term data and large cohort study on renal function or tumor recurrence are still absent which will be necessary to confirm the advantages of this approach.

Abstract
OBJECTIVE To evaluate the clinicopathologic features and potential prognostic predictors of locally recurrent renal cell carcinoma patients after initial surgery. METHODS Authors retrospectively analyzed data extracted from 81 patients who were treated for postoperative locally recurrence of renal cell carcinoma from January 2006 to June 2016 in the Department of Urology, Peking University First Hospital. Postoperative locally recurrence of renal cell carcinoma was defined as disease recurring in the remnant kidney, renal fossa, adjacent abdomen, ipsilateral adrenal and retroperitoneal lymph nodes. RESULTS In the study, 81 patients were finally included, of whom 43 were initially treated in our hospital and 38 were initially treat in other centers. Partial nephrectomy (PN) was performed for 38 cases (26 in our hospital and 12 in other hospitals) as initial treatment and radical nephrectomy (RN) was conducted for the remnant 43 cases (17 in our hospital and 26 in other hospitals). Overall median recurrence time was 26 months (range: 3-164 months), in which 26 months (range: 3-55 months) for PN cases and 30 months (range: 4-164 months) for RN cases (P=0.009). Sixty-nine patients had single site recurrence, including remnant kidney (n=29), renal fossa (n=20), abdomen (n=4), ipsilateral lymph nodes (n=5), ipsilateral adrenal (n=11), while 12 patients had multiple sites recurrence. Seventy-eight patients were managed by complete surgical resection, while three patients were managed by radiofrequency ablation. Postoperative pathological diagnoses included clear cell carcinoma (n=72), papillary renal cell carcinoma (n=8, 7 cases with type 1, 1 case with type 2) and Xp11 translocation/TFE3 gene fusion renal cell carcinoma (n=1). Complete pathologic information of the initial surgery could be extracted from 43 patients who were initially treated in our hospital. Seventeen patients with initial radical nephrectomy were staged as T1a (n=4), T1b (n=2), T2a (n=1), T3a (n=8), and T3b (n=2). Twenty-six patients with initial partial nephrectomy were staged as T1a (n=18), T1b (n=7), and T3a (n=1). For PN cohort, the patients with T1a stage disease had longer median recurrence time than those with beyond T1a stage disease, and the difference was significant (29 months vs. 18 months, P=0.041). At the end of the follow-up, 58 patients were alive, 4 died and 19 lost the follow-up. Overall, 3-year and 5-year disease free survival rates were 81.9%, and 53.6%, respectively. CONCLUSION The present research reported a large-scale single central experience of locally recurrent renal cell carcinoma. The recurrence time of the PN group is shorter than that of the RN group. For patients after PN surgery, median recurrence time is longer for patients with T1a stage tumor when compared with those with stage beyond T1a. Patients can obtain relative long-term survival after complete secondary surgery resection.

Abstract
Ureteral injury can be classified as iatrogenic or traumatic, which represents a rare but challenging field of reconstructive urology. Due to their close proximity to vital abdominal and pelvic organs, the ureters are highly susceptible to iatrogenic injury, while ureteral injury caused by external trauma is relatively rare. The signs of ureteric injury are difficult to identify initially and often present after a delay. The treatment of ureteral injury, which is depended on the type, location, and degree of injury, the time of diagnosis and the patient's overall clinical condition, ranges from simple endoscopic management to complex surgical reconstruction. And long defect of the ureter presents much greater challenges to urologists. Ureterotomy under endoscopy using laser or cold-knife is available for the treatment of 2-3 cm benign ureteral injuries or strictures. Pyeloplasty is an effective treatment for ureteropelvic junction obstruction and some improved methods showed the possibility of repairing long-segment (10-15 cm) stenosis. Proximal and mid-ureteral injuries or strictures of 2-3 cm long can often be managed by primary ureteroureterostomy. When not feasible due to ureteral defects of longer segment, mobilization of the kidney should be considered, and transureteroureterostomy is alternative if the proximal ureter is of sufficient length. And autotransplantation or nephrectomy is regarded as the last resorts. Most of the injuries or strictures are observed in the distal ureter, below the pelvic brim, and are usually treated with ureteroneocystostomy. A non-refluxing technique together with a ureteral nipple or submucosal tunnel method, is preferable as it minimizes vesico-ureteral reflux and the risk of infection. In order to cover a longer distance, ureteroneocystostomy in combination with a psoas hitch (covering 6-10 cm of defect) or a Boari flap (covering 12-15 cm) is often adopted. Among various ureteral replacement procedures, only intestinal ureteral substitution, which includes ileal ureter, appendiceal interposition and reconfigured colon substitution, has gained wide acceptance when urothelial tissue is insufficient. Ileal ureter can be used to replace the ureter of >15 cm defect and even to replace the entire unbilateral ureter or bilateral ureter. Laparoscopic and robotic-assisted techniques are increasingly being employed for ureteral reconstruction and adopted with encouraging results.

Abstract
OBJECTIVE To investigate the efficacy of intraoperative cognitive navigation on laparoscopic radical prostatectomy using 3D prostatic models created by U-shaped convolutional neural network (U-net) and reconstructed through Medical Image Interaction Tool Kit (MITK) platform. METHODS A total of 5 000 pieces of prostate cancer magnetic resonance (MR) imaging discovery sets with manual annotations were used to train a modified U-net, and a set of clinically demand-oriented, stable and efficient full convolutional neural network algorithm was constructed. The MR images were cropped and segmented automatically by using modified U-net, and the segmentation data were automatically reconstructed using MITK platform according to our own protocols. The modeling data were output as STL format, and the prostate models were simultaneously displayed on an android tablet during the operation to help achieving cognitive navigation. RESULTS Based on original U-net architecture, we established a modified U-net from a 201-case MR imaging training set. The network performance was tested and compared with human segmentations and other segmentation networks by using one certain testing data set. Auto segmentation of multi-structures (such as prostate, prostate tumors, seminal vesicles, rectus, neurovascular bundles and dorsal venous complex) were successfully achieved. Secondary automatic 3D reconstruction had been carried out through MITK platform. During the surgery, 3D models of prostatic area were simultaneously displayed on an android tablet, and the cognitive navigation was successfully achieved. Intra-operation organ visualization demonstrated the structural relationships among the key structures in great detail and the degree of tumor invasion was visualized directly. CONCLUSION The modified U-net was able to achieve automatic segmentations of important structures of prostate area. Secondary 3D model reconstruction and demonstration could provide intraoperative visualization of vital structures of prostate area, which could help achieve cognitive fusion navigation for surgeons. The application of these techniques could finally reduce positive surgical margin rates, and may improve the efficacy and oncological outcomes of laparoscopic prostatectomy.

Abstract
Summary Deformity of the auricle can result from congenital defects, oncologic resection, or traumatic injury. Current clinical strategy is to utilize autologous costal cartilage for reconstructing auricular scaffolds with long-term stability. However, this method is limited by donor-site morbidity, a complex surgical sculpting process, and differing mechanical properties compared to elastic auricular cartilage. Alternatively, alloplastic implants can offer precise shape and avoid donor-site surgery, but suffer from poor biocompatibility and high rates of infection and extrusion. A tissue engineering approach to auricular reconstructions would overcome the limitations of both autologous and alloplastic transplants. In this review we focus on tissue engineering auricular cartilage reconstruction, including auricular seed cells culture and their differentiated control strategy, scaffolds choices and design technique. Many studies found that auricular chondrocytes were the most suitable seed cells to fabricate elastic cartilage; progenitor cells from auricular cartilage could differentiate into elastic chondrocytes, and other types of chondrocytes had its limitation because of the final ossification. Many types of growth factors had the differing potential ability for accelerating chondrocytes growth, differentiation, or maintaining chondrocytes phenotype. Recent advances in tissue engineering auricular cartilage, including several clinic applications, implied that tissue engineering auricules would become a hopefully potential soulution for the future of auricular reconstruction.

Abstract
Objective:To assess the role of LPR in the development of complications, such as hemorrhage, following tonsillectomy in adult patients. We want to provide a guidence for future clinical practice.Method:Totally 70 adult patients who had indication of tonsillectomy were recruited and divided into two groups, the laryngopharyngeal reflux (LPR) group and the control group, which were identified by the results of Reflux Symptom Index (RSI) and Reflux Finding Score (RFS). We observed and compared the postoperative complications of the two groups and analyzed the role of LPR.Result:All the patients complained pain after surgery. The duration of the pain in LPR group was much longer than that of control group. The mean body temperature in both groups was not significantly different (P>0.05). There were six cases of bleeding in the LPR group, while only one case of bleeding occurred in the control group. The difference was statistically significant (P<0.05). There were no cases of infection or pulmonary complications in both groups. All patients were discharged successfully.Conclusion:LPR is closely related to the complications following tonsillectomy.

Abstract
Objective: To study the relationship between the average hearing of different frequencies and the audiometry staging in patients with Meniere's disease. Methods: A total of 259 patients from 1996 to 2016 were collected .All patients underwent pure tone audiometry, of which 93 patients underwent 3 000 Hz audiometry. The patients were divided into five groups according to the frequencies of hearing(Ⅰ: 500, 1 000, 2 000, 3 000 Hz; Ⅱ: 250, 500, 1 000, 2 000, 3 000 Hz; Ⅲ: 250, 500, 1 000, 2 000; Ⅳ: 500, 1 000, 2 000, 4 000 Hz; Ⅴ: 500, 1 000, 2 000 Hz), then calculated the average audiometry and made the hearing staging. The obtained data were analyzed by chi-square test and Bonferroni correction was performed among the groups, P<0.05 was defined as a statistically significant criterion. Result: There were no significant difference between the five groups(P=0.441>0.05). Conclusions: The choice of different pure tone audiometry frequency has no significant effect on the hearing staging. It would be more likely upstaging when plus 250 Hz. There is no statistically significant difference in staging between the latest guidelines and the 1995 guidelines.500, 1 000 and 2 000 Hz are recommended when 3 000 Hz examine is not available.

Abstract
Objective: To investigate the imaging diagnosis, treatment and prognosis of primary hepatic neuroendocrine tumors. Methods: The clinical features, imaging manifestations, histopathological and immunohistochemical findings and interventional therapy of 6 patients identified with pathologically confirmed primary hepatic neuroendocrine tumors were retrospectively analyzed, and the related literatures were reviewed. Results: All 6 patients presented with symptoms of abdominal pain. 4 patients had solitary hepatic mass and 2 patients had multiple hepatic masses. Magnetic resonance imaging showed low signal intensity on T1 weighted imaging, high signal intensity on T2 weighted imaging and clear boundary; the arterial phase of enhancement scan was uneven and enhanced, and portal venous phase or delayed phase showed continuous enhancement, surrounded by ring enhanced capsule. A pathological diagnosis was primary neuroendocrine tumor of the liver. After interventional treatment, 6 patients had some therapeutic effects. Among them, 4 patients underwent multiple interventional therapies, followed by 4 years of follow-up has shown satisfactory results. Conclusion: Primary hepatic neuroendocrine tumors are very rare and their imaging manifestations are specific. Eventually, relies on pathological and immunohistochemical diagnosis. Transarterial chemoembolization therapy can bring satisfactory results in the treatment of primary hepatic neuroendocrine tumor.

Abstract
Objective: To study the clinical characteristics, image findings, therapeutic method and prognosis of metanephric adenoma. Method: The clinical characteristic, image findings, operation methods and prognosis of 16 metanephric adenoma patients treated at Department of Urology, Peking University First Hospital from January 2004 to March 2016 were analyzed retrospectively. Results: There were 6 male and 10 female patients in the study. The mean age of patients was 33.7 years (ranging from 14 to 83 years). Two patients came to the hospital because of fever, while other 14 patients had no symptoms and found renal tumor by medical examination. One case was found polythemia vera and another 1 case showed mild anemia. Serum creatine of all the cases were in normal range. The tumor of 11 cases were at left side and 5 cases were at right. All patients took urinary tract ultrasound. Fifteen patients took CT examination. Among them, 14 cases were solid mass and 1 case was cystosolid.CT value was (41±4) HU. CT scan showed that the tumor was slight enhanced and CT value increased to (77±9) HU. Six patients took MRI examination. The MRI showed high or low signal of T1WI or T2WI scans.Tumor size was (4.7±3.9)cm (ranging from 1.7 to 17.5 cm). All 16 patients took operation and 11 of them took laparoscopic surgery while the other 5 cases took open surgery. Eleven cases took partial nephrectomy, 4 cases took nephrectomy and 1 case took nephroureterectomy. The surgical procedures were all successful and no complications occured during perioperative period. All cases were all confirmed metanephric adenoma by postoperative pathology and surgery cut edge were all negative. Immunohistochemical study showed that the positive rate of Vimentin, CD57, AE1/AE3, WT1, CK7 and AMACR respectively were 16/16, 15/16, 12/16, 10/16, 3/16 and 2/16. The median follow-up time of 16 cases was 44 months (ranging from 8 to 125 months) and none had recurrence or metastasis.One case died 125 months after surgery because of advanced age(83 years old). Conclusions: Metanephric adenoma is difficult to be diagnosed relying on clinical characteristics and image features. Pathology can help confirm the diagnosis. Partial nephrectomy is the first choice for operation and can achieve good prognosis. But it still needs a regular follow-up.

Abstract
Objective: To investigate the value of preoperative dynamic contrast-enhanced MRI in reducing the rate of tumor-positive resection margins after breast conserving surgery in patients with early non-mass breast carcinoma. Methods: Seventy-two patients with early non-mass breast carcinoma received ultrasonographic and mammographic examination and subsequently underwent dynamic contrast-enhanced MRI examination before breast conserving surgery. The control group consisted of 74 patients who had early non-mass breast carcinoma. They only received ultrasonographic and mammographic examination and didn't undergo contrast-enhanced MRI examination. The comparison of the rate of tumor-positive resection margins between two groups was performed. The MRI findings that had the significant influence on the rate of tumor-positive resection margins were analyzed using Logistic regression model. Results: In 28 patients (28/72, 38.9%), dynamic contrast-enhanced MRI could correct or supplement the ultrasonographic and mammographic findings and resulted in the reasonable change of surgical program. The preoperative MRI examination group (n=30) had lower rate of tumor-positive resection margins than control group for invasive ductal carcinoma (23.3% vs 40.0%, P=0.02), but there was no significant difference (21.4% vs 26.9%, P=0.10) between two groups for ductal carcinoma in situ (n=28). The preoperative MRI examination group (n=14) had lower rate of tumor-positive resection margins than control group for the other pathologic types of breast carcinoma (14.3% vs 38.9%, P=0.02). The statistical analysis on the basis of Logistic regression model showed that some main MRI findings, including change surrounding the tumor, distance between tumor and nipple and tumor size, had the significant influence on the rate of tumor-positive resection margins. Conclusion: Preoperative dynamic contrast-enhanced MRI significantly increased the accuracy of resection margins evaluation, and greatly reduced the rate of tumor-positive resection margins after breast conserving surgery in patients with early non-mass breast carcinoma.

Abstract
Objective: To study the impact to operation safety of preoperative renal artery embolization for management of ≥10 cm renal cell carcinoma. Methods: The clinical data of 239 cases with ≥10 cm renal cell carcinoma which all had underwent operation in Department of Urology, Peking University First Hospital from January 2002 to December 2014 were retrospectively analyzed. Fifty-three patients underwent preoperative renal artery embolization (therapeutic group) and 186 patients did not (control group). The effect of embolization on operative time, transfusion requirements, hospitalization, ICU stay and perioperative complications were analyzed by comparing the two groups using rank sum test and χ(2) test or Fisher exact test. Results: Comparing the therapeutic group and control group, there was significant difference in tumor location (on the left or right). The mean age, sex, mean primary tumor size, and TNM stage were similar in both groups. Comparing the therapeutic group and control group, there were more open surgeries in therapeutic group (96.2% vs. 82.3%, χ(2)=6.438, P=0.013). There were no significant differences in mean operative time (238 (525) minutes vs. 208 (583) minutes, Z=-2.182, P=0.062). The mean blood transfusion (700 (1 900) ml vs. 925 (8 800) ml, Z=-1.064, P=0.006) had significant difference. The therapeutic group had a longer mean hospitalization (21 (50) days vs. 15 (79) days, Z=-4.322, P=0.000) and higher rate of intensive care unit stay (54.7% vs. 34.4%, χ(2)=6.103, P=0.027). There was no significant difference in perioperative complications between two groups (0 vs.3.2%, P=0.408). Conclusion: Preoperative renal artery embolization in ≥10 cm renal cell carcinoma patients undergoing operation provides benefit in increasing operation safety and reducing perioperative death.

Abstract
OBJECTIVE To assess the diagnostic rate, safety and clinical application of percutaneous renal masses biopsy for advanced renal cell carcinoma patients. METHODS In this retrospective study, we collected the data of renal masses from the patients who underwent renal masses biopsy under ultrasound from April 2001 to December 2014 in Peking University First Hospital. A total of 75 patients who were undiagnosed or diagnosed with advanced renal cell carcinoma by the imageological method were enrolled in this study. The patient and lesion characteristics such as tumor size, pathology of tumor, histologic subtype, pathological grade, biopsied location and biopsied cores were recorded and analyzed. RESULTS Among all the 75 patients, biopsy was diagnostic in 64 cases (85.3%) and non-diagnostic in 11 cases (14.7%). Of the 64 diagnostic biopsies, 60 were malignant, including 37 (61.7%) renal cell carcinoma (RCC), 13 (21.7%) urothelial carcinoma and 10 (16.7%) other malignant masses. Of all the RCC subjects, 24 suffered from clear cell RCC, 5 papillary RCC, 3 collecting duct carcinomas, 1 unclassified RCC and 4 unknown subtypes. The 11 non-diagnostic biopsied samplings included inflammatory, blood and extrarenal tissue and normal renal tissue. The proportion of collecting duct carcinoma in RCC was 10.8% and the proportion of squamous carcinoma in urothelial carcinoma was 23.1%, which were both higher than the previous research findings. For the male and female groups, non-diagnostic yields were 6.5% and 30.4%, respectively (P=0.022). Of all the 75 patients, 13 renal cell carcinoma patients underwent the surgical treatment and got the results of postoperative pathology. Comparing preoperative biopsy pathological diagnosis with postoperative pathological diagnosis, we found the diagnostic correct rates for benign and malignant lesions, pathological subtype and pathological grade were 100%, 81.8% and 60%, respectively. Mild macroscopic hematuria occurred in 1 case after RMB and there were no serious complications in all the cases. CONCLUSION Percutaneous renal masses biopsy under ultrasound with a high diagnostic rate which can define the histologic subtype of renal cell carcinoma. With targeted therapy, more and more patients whose evaluation suggests local advanced disease or metastatic tumors adopt renal tumor biopsy to define the histologic subtype, which could avoid unnecessary surgical treatment.

Abstract
Objective: To detect the effect of brain cytoplasmic RNA 1 (BCYRN1) on the proliferation and migration of airway smooth muscle cells (ASMCs) in rat model of asthma. Methods: Male SD rats were randomly divided into control group and asthma group (n=10 each). The ovalbumin (OVA) model was constructed in asthma group. Real time-qPCR was performed to detect the level of BCYRN1 in the ASMCs separated from the airway tissue of these rats. Then 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-(2, 4-disulfophenyl)-2H-tetrazolium (WST-1) assay, roche real-time cell analyzer assay and Transwell cell migration assay were performed to detect the viability/proliferation and migration of ASMCs which were transfected with Ad-BCYRN1.Platelet-derived growth factor (PDGF)-BB was used to treat ASMCs to induce proliferation and migration, and the level of BCYRN1 was examined.The viability/proliferation and migration of ASMCs treated with PDGF-BB and transfected with si-BCYRN1 were detected. Inspiratory resistance and expiratory resistance were measured in rats with BCYRN1 knockdown.Briefly, rats were randomly divided into four groups: control (group A), sensitization + Ad-GFP (group B), sensitization + AdSM22α-siBCYRN1 (group C), control + Ad-SM22α-siBCYRN1 (group D) (n=10 each). The corresponding adenovirus vectors were sent to lung of group B, group C and group D through nasal spray. The OVA model was constructed in group B and group C. The rats in group A and group D were treated with saline.After 24 h of the last treatment with OVA or saline, rats of each group were given tracheal intubation, connected with breathing machine. Rats were injected with methacholine to measure the inspiratory resistance and expiratory resistance. Results: The level of BCYRN1 in ASMCs separated from rats in asthma group and in ASMCs treated with PDGF-BB was 3.60±0.45 and 3.53±0.35, respectively, significantly higher than those of the corresponding control (both P<0.01). Ad-BCYRN1 significantly increased the expression of BCYRN1 in ASMCs. The cell viability and proliferation rates of ASMCs transfected with Ad-BCYRN1 increased 1.75-and 1.47-fold compared to those of the control group, respectively (P<0.01); mobility increased 2.42-fold compared to that of the control group (all P<0.01). BCYRN1 knockdown reversed the increasing proliferation and migration of ASMCs induced by PDGF-BB. The cell proliferation rate and cell migration number in the PDGF-BB treatment group were (4.87±0.21)% and 80.00±5.00, respectively, which were significant higher than those in the si-BCYRN1 transfected group ((3.63±0.21)% and 25.33±2.52, all P<0.01). BCYRN1 knockdown reduced the inspiratory resistance and expiratory resistance in sensitization + Ad-SM22α-siBCYRN1 group. When the concentration of acetylcholine reached 1 mg/kg, the inspiratory resistance in the group A, group B, group C, and group D were 8.27±0.21, 25.40±0.56, 12.07±0.67 and 8.40±0.46 cmH2O·s·ml-1, and expiratory resistance were 13.30±0.56, 38.37±1.33, 16.40±0.56 and 13.40±0.46 cmH2O·s·ml-1, respectively (all P<0.01). Conclusion: Overexpression of BCYRN1 promotes the proliferation and migration of ASMCs in rat model of asthma.

Abstract
OBJECTIVE To explore risk factors including prostate-specific antigen (PSA) kinetics for the prediction of castration-resistant prostate cancer (CRPC), and to build a practical model for predicting the progression to CRPC after androgen deprivation therapy (ADT) so as to facilitate clinicians in decision-making for prostate cancer patients receiving ADT. METHODS A total of 185 patients with prostate cancer who had received ADT as the primary therapy in Department of Urology of Peking University First Hospital from 2003 to 2014 were enrolled retrospectively. All the patients were diagnosed with prostate cancer via prostate biopsy and followed up every four weeks from the initiation of ADT. All the patients received ADT with luteinizing hormone-releasing hormone agonists (LHRH-A) or surgical castration accompanied with an antiandrogen (bicalutamide or flutamide, combined androgen blockade). The clinical information of the patients were collected including age, clinical TNM stage, Gleason score (GS), risk groups of prostate cancer, PSA at the initiation of ADT, PSA nadir after ADT, PSA decline velocity, and the time to PSA nadir. The end point of this study was the diagnosis of CRPC, which was based on the European Association of Urology (EAU) Guideline 2016. Cox proportional hazards regression models were established to analyze and estimate their effects on the time of progression to CRPC. RESULTS In this study, 185 patients with prostate cancer who had received ADT as the primary therapy were included. The mean age was (71.02±8.67) years. The median time to progression to CRPC in this cohort was 38 months (ranging from 4 to 158 months). On univariate analysis, we found clinical T stage, N stage, the metastasis state before ADT, risk groups of prostate cancer, PSA decline velocity, and PSA nadir were all related to the time to CRPC progression, P<0.01 for all the above variables. And on multivariate analysis, the presence of distant metastasis before ADT (HR=6.030, 95% CI: 3.229-11.263, P=0.001), higher PSA nadir (HR=1.185, 95% CI: 1.080-1.301, P=0.001), higher PSA decline velocity>11 μg/(L×month) (HR=2.124, 95% CI: 1.195-3.750, P=0.001), and time to PSA nadir ≤9 months (HR=3.623, 95% CI: 1.640-4.817, P=0.004) were found to be significantly associated with an increased risk of progression to CRPC. CONCLUSION Patients with rapid decreasing of PSA in the initial ADT were more likely to progress to CRPC.

Abstract
OBJECTIVE To evaluate the impacts of the prognostic factors of T2N0M0 upper tract urothelial carcinoma (UTUC) for Chinese patients. METHODS A retrospective study was conducted including 235 patients who were diagnosed with T2N0M0 UTUC in our hospital and received radical nephroureterectomy (RNU) or partial ureterectomy during January 2000 and December 2013. The 3 and 5-year cancer-specific survival rates and bladder recurrence-free survival rates of all the patients were valued using Kaplan-Meier method, and the survival curves with statistical significance between the two were compared using the Log-rank test. Variables with significant differences in the univariate analysis were subjected to the multivariate analysis by Cox regression model. RESULTS A total of 235 patients were included in this study, including 95 (40.4%) male patients and 140 (59.6%) female patients. The mean age was 66.73±10.49 years.The median follow-up time was 53 (rang: 3-142) months, and during the follow-up, 74 (31.5%) patients died of UTUC after a median of 35 months,and 96 (40.9%) patients developed intravesical recurrence after a median of 19.5 months. The 3 and 5-year cancer-specific survival rates of all the patients were 89.1% and 85.9%, respectively; the bladder recurrence-free survival rates were 85.5% and 80.2%, respectively. The independent prognostic factors of cancer-specific mortality were tumor age elder than 55 years (HR=3.138, 95%CI: 1.348-7.306, P=0.008) and diameter larger than 5 cm (HR=3.320, 95%CI: 1.882-5.857, P<0.001). The independent prognostic factors of bladder recurrence-free survival were ureter tumor (HR=1.757, 95%CI: 1.159-2.664, P=0.008) and lower tumor grade (HR=1.760, 95% CI: 1.151-2.692, P=0.009). CONCLUSION T2N0M0 UTUC has a better cancer-specific survival. The intravesical recurrence was equivalent to non-muscle invasive UTUC but earlier. The tumor diameter larger than 5 cm and the patient age elder than 55 years were independently associated with cancer-specific mortality; the primary tumor located in ureter and lower tumor grade were more likely to develop intravesical recurrence.

Abstract
OBJECTIVE To investigate the mechanisms of nuclear export signal of androgen receptor (NESAR) in the regulation of androgen receptor (AR) protein expression and stability in prostate cancer. METHODS The green fluorescent protein fusion protein expression vectors pEGFP-AR(1-918aa), pEGFP-NESAR (743-817aa), pEGFP-NAR (1-665aa) and pEGFP-NAR-NESAR, and lysine mutants of NESAR pEGFP-NESAR K776R, pEGFP-NESAR K807R and pEGFP-NESAR K776R/K807R, were transiently transfected into prostate cancer cell line PC3. Fluorescence microscopy, Western blot and immunoprecipitation were used to detect NESAR regulation of androgen receptor stability. RESULTS Under the fluorescence microscope, NESAR-containing fusion proteins were cytoplasmic localization, and their fluorescence intensities were much weaker than those without NESAR. The expression levels of NESAR-containing fusion proteins were significantly lower than those without NESAR. The half-lives of GFP-NESAR and GFP-NAR-NESAR were less than 6 h, while the expression of GFP and GFP-NAR was relatively stable and the half-life was more than 24 h in the presence of cycloheximide. The expression levels of GFP-NESAR were significantly increased by proteasome inhibitor MG132 treatment in a dose-dependent manner; in contrast, MG132 did not show any significant effect on the protein levels of GFP. When new protein synthesis was blocked, MG132 could also prevent the degradation of GFP-NESAR in the transfected cells in the presence of cycloheximide, while it had no significant effect on GFP protein stability in the parallel experiment. GFP immunoprecipitation showed that the ubiquitination level of GFP-NESAR fusion protein was significantly higher than that of the GFP control. The mutations of lysine sites K776 and K807 in NESAR significantly reduced the level of ubiquitination, and showed increased protein stability, indicating that they were the key amino acid residues of NESAR ubiquitination. CONCLUSION NESAR was unstable and decreased the stability of its fusion proteins. NESAR was the target of polyubiquitination and mediated the degradation of its fusion proteins through the ubiquitin-proteasome pathway in prostate cancer cells. Our research provides a new way to regulate the level and/or activity of AR proteins, thus helping us understand the molecular mechanisms of AR degradation and strict control of AR in the progression to castration-resistance.

Abstract
Objective: To analyze the influence of growing experience on non-heterosexual orientation among male college students. Methods: From October to November in 2015, a total of 2 535 male students from 96 classes in 14 colleges/departments were recruited from two colleges that participated in the experimental work of AIDS prevention by cluster random sampling method. A structured questionnaire was administered in this study, including general demographic information, growing experience and Kinsey scale (to evaluate sexual orientation). Out of 2 500 questionnaires distributed in this study, 2 332 effective copies were withdrew, with the effective rate at 93.3%. Chi square test was used to analyze the differences of non-heterosexual orientation among the individuals with different social demographic characteristics. Multivariate logistic regression model was used to analyze the influencing factors of non-heterosexual orientation. Results: Among the 2 332 individuals, the proportion of self-reported non-heterosexual was 6.2% (144).The proportions of male students who identify as non-heterosexual from freshman to junior year were 5.2%(63/1216),6.9%(65/941),11.7%(13/111) and 4.7%(3/64), respectively (χ(2)=9.06,P=0.029). Compared with the individuals of very good relationship with parents, those with bad relationship (OR=3.3, 95%CI: 1.7-6.5) and general relationship (OR=1.7, 95%CI: 1.0-2.9) with parents had a higher risk of non-heterosexual orientation, respectively. Those encountered sexual assault had a higher risk of non-heterosexual orientation than those without encountered sexual assault (OR=5.9, 95%CI: 3.2-10.9). Conclusions: This study reported a high proportion of self-reported non-heterosexual among college male students in Nanjing, and highlighted the importance of targeting students with poor parental relationships and who subjected to sexually abused.

Abstract
Engineering a small diameter vascular graft with mechanical and biological properties comparable to living tissues remains challenging. Often, current devices lead to thrombosis and unsatisfactory long-term patency as a result of poor blood compatibility and a mismatch between the mechanical properties of the living tissue and the implanted biomaterial. Addressing all these requirements is essential to produce scaffolds able to survive throughout the life of the patient. For this purpose, we fabricated a novel three-layered vascular graft by combining electrospinning and braiding. Mirroring the structure of human blood vessels, the proposed device is composed of three layers: the intima, the media, and the adventitia. The intima and media layers were obtained by sequentially electrospinning silk fibroin (SF) and poly(L-lactide-co-ε-caprolactone), with ratios selected to match the mechanical properties of the native tissue. For the outer layer, the adventitia, SF yarns were braided on top of the electrospun tubes to create a structure able to withstand high pressures. Compliance, Young's modulus and deformability of the obtained scaffold were similar to that of human blood vessels. Additionally, cytocompatibility of the two layers, media and intima, was assessed in vitro by analysing cell metabolic activity and proliferation of endothelial cells and smooth muscle cells, respectively. Furthermore, heparin functionalization of the scaffolds led to improved anticoagulant properties upon incubation in whole blood. The obtained results indicate a potential application of the herewith designed three-layered construct as a vascular graft for small diameter blood vessel engineering.

Abstract
OBJECTIVE To identify the preoperative prognostic factors of upper tract urothelial carcinoma (UTUC) and construct preoperative risk stratification system. METHODS A retrospective study including 686 patients who were diagnosed with UTUC and received radical nephroureterectomy or partial ureterectomy in Peking University First Hospital during 2003 and 2013. RESULTS Of the 686 UTUC patients, 303 (44.2%) were male and 383 (55.8%) female. The postoperative pathological examination showed that 203 (29.6%) had high tumor stages (T3, T4), 300 (43.7%) had high tumor grades (G3) and 54 (7.9%) had lymph nodes metastasis (N1). After multivariate analysis, renal pelvic tumor, large tumor, estimated glomerular filtration rate (eGFR)≥30 mL/min, and male were associated with high tumor stage. Ureteral tumor, large tumor, and non-smoking history were associated with high tumor grade. Renal pelvis tumor, large tumor, and preoperative anemia were associated with positive N status. During the follow-up, 208 (30.3%) died for cancer and 210 (30.6%) developed intravesical recurrence. Multivariate analysis showed: large tumor (P=0.001), concomitant ipsilateral hydronephrosis (P=0.041), and preoperative anemia (P=0.001) were independently associated cancer-specific mortality after surgery, while ureteral tumor (P=0.04), multiple tumor (P=0.005), and high preoperative creatinine (P=0.036) were independent risk factors for intravesical recurrence. CONCLUSION Of the preoperative clinical parameters of UTUC patients, the large tumor, concomitant ipsilateral hydronephrosis, and preoperative anemia were independently associated with cancer-specific mortality after surgery. Ureteral tumor, multiple tumor, and high preoperative creatinine were independently associated with intravesical recurrence after surgery.

Abstract
OBJECTIVE To evaluate the impacts of clinical, pathological, and laboratory factors on oncological outcomes of patients with T3N0M0 renal cell carcinoma. METHODS The clinical data, laboratory exam results, and follow-up outcomes of 182 patients with T3N0M0 renal cell carcinoma who underwent nephrectomy from 2007 to 2012 in Peking University First Hospital were retrospectively collected. The 5-year cancer-specific survival and 5-year recurrence-free survival of all the patients were calculated using Kaplan-Meier method, and the statistical significance between the survival curves were compared using the Log-rank test. Variables with significant differences in the univariate analysis were subjected to the multivariate analysis by Cox regression model. All the comparisons were conducted using two-tailed test and P<0.05 was considered statistically significant. RESULTS A total of 182 patients were included in this study. Of all the 182 patients, 126 were male (69.23%) and 56 were female (30.77%). The mean age was (56.75±12.45) years. The median follow-up time was 48 months (3-99 months). At the end of the follow-up, 50 patients (27.47%) died due to the disease after a median of 29.74 months and 59 patients (32.42%) had tumor recurrence after a median of 22.12 months. The 5-year cancer-specific survival of all patients was 68.30% (95% CI: 60.16%-75.84%); the 5-year recurrence-free survival was 60.70% (95% CI: 53.16%-68.84%). In the univariate analysis, diabetes mellitus, tumor invasion status, Fuhrman grade, serum album, serum cholestenone, anemia, and neutrophils percentage were associated with the cancer-specific survival and Fuhrman grade, serum album and anemia were associated with the recurrence-free survival. Variables with significant differences on univariate analysis were included in Cox multivariate regression analysis. Multivariate Logistic regression analysis showed that diabetes mellitus (HR=2.434, 95% CI: 1.243-4.769, P=0.010), hypoalbuminemia (HR=2.188, 95% CI: 1.074-1.074, P=0.031), and anemia (HR=3.320, 95% CI: 1.839-5.991, P<0.001) were independent risk factors significantly associated with cancer-specific survival; and higher Fuhrman grade (HR=2.552, 95% CI: 1.433-4.545, P=0.001), anemia (HR=2.535, 95% CI: 1.497-4.293, P=0.001) were independent factors significantly associated with recurrence-free survival. CONCLUSION Diabetes mellitus, hypoalbuminemia, and anemia were independent risk factors significantly associated with cancer-specific survival of T3N0M0 renal cell carcinoma patients; higher Fuhrman grade and anemia were independent risk factors significantly associated with tumor recurrence of T3N0M0 renal cell carcinoma patients.

Abstract
OBJECTIVE To discuss the therapy for ureteral endometriosis. METHODS The clinical data of 25 cases of histopathologically confirmed ureteral endometriosis during 2001-2015 were retrospectively analyxed. RESULTS In the 25 cases, all the patients took urinary ultrasound for examination before surgery, of whom 21 (84%) were examined by CT and 5 (20%) by MRI. Three (12%) cases underwent preoperative KUB and intravenous pyelogram (IVP) examination. Four (16%) cases were examined by retrograde pyelography before surgery. Eight (32%) of them took cystoscope for examination and 11 (44%) took preoperative radionuclide renal dynamic imaging examination. All of these cases were affected with unilateral ureter, 13 (52%) in the right and 12 (48%) in the left. The ureter lesions were at the upper part in 21 (84%) cases and at the middle part in 4 (16%) cases. In these cases, 11 (44%) received partial ureteral resection and end-to-end ureteral anastomosis, 10 (40%) received partial ureteral resection and ureterocystoneostomy, 3 (12%) received retroperitoneal laparoscopic nephroureterectomy, and 1 (4%) received endoscopic resection of ureteral endometriosis lesion. All of these cases were confirmed with ureteral endometriosis by post-surgery pathology results, with the expression of CA125 and ER in the glandular tissue and expression of PR in the mesenchymal tissue inside the ureteral muscle detected by immunohistochemistry. Four (16%) cases took postoperative adjuvant hormonal therapy. And no recurrence was found among 16 (64%) cases with the successful follow-up which ranged from 3 to 76 months and the median follow up was 28 months. Fifteen cases were submitted to the follow-up by urinary ultrasound (93.8%) and 5 (31.3%) underwent CT for examination. All the cases relieved from hydronephrosis, and symptoms of 10 (63.5) cases disappeared. The cases with double-J stent all had the stent removed within 3 to 6 weeks. CONCLUSION Surgical procedures should be considered as the main therapy for ureteral endometriosis. We recommend ureterolysis for patients with mild ureteral obstruction and hydronephrosis. As for those with moderate and severe ureteral obstruction and hydronephrosis, we recommend partial ureteral resection. When the situation comes to patients with little renal function of the affected side, the recommended management is nephroureterectomy.

Abstract
OBJECTIVE Carcinoma of bladder is the most common malignancy in the urinary system in China. Most patients with this disease had non-muscle invasive bladder cancer (NMIBC) at the time of diagnosis. Radical cystectomy was indicated for patients with high risk or refractory NMIBC. We aimed to investigate the overall survival and disease-specific survival and related influence factors in patients undergoing radical cystectomy for pathological non-muscle invasive bladder cancer. METHODS From Jan. 2006 to Dec. 2012, a total of 164 patients with pathological non-muscle invasive bladder cancer underwent radical cystectomy in Peking University First Hospital. Clinical data were retrospectively collected.Incidence of lymph node metastasis and disease recurrence were calculated. The risk factors of disease recurrence were analyzed. Kaplan-Meier plots were used to estimate the overall survival and cancer-specific survival. Multivariate Cox regression analysis was used to evaluate the prognostic factors for survival. RESULTS Of all the patients included, 159 had T1 disease, and 5 had CIS only. The median follow-up duration was 46.5 months (range: 7-99 months). Fourteen patients were lost during the follow-up. Lymph node metastasis was noted in 6 patients (3.7%), 4 patients had N1 disease, one patient had N2 disease, and one patient had N3 disease. Disease recurrence occurred in 16 patients (9.8%).The most common recurrence sites were the liver, bones, and lungs. The 5-year overall survival and disease-specific survival for all the patients were 85% and 91%, respectively. The patients who underwent pelvic lymph node dissection showed a better prognosis in terms of disease-specific survival than those without (P=0.012). Patients with recurrence harbored a significant poorer survival (P<0.001). According to univariate Cox regression analysis, whether lymph node dissection was performed was an independent risk factor of disease recurrence (P=0.050, OR=2.695, 95%CI 0.999-7.271). In COX regression model, age (P=0.008, OR=1.071, 95%CI 1.018-1.126) and whether lymph node dissection was performed (P=0.011, OR=3.385, 95%CI 1.329-8.621) were related to disease-specific survival. CONCLUSION Patients with pathological non-muscle invasive bladder cancer underwent early radical cystectomy have a favorable prognosis, and bilateral pelvic lymph node dissection is essential for this procedure as it gains a survival benefit for the patients.

Abstract
OBJECTIVE To investigate the methylation status of the RASSF1A gene promoter in upper tract urothelial carcinoma (UTUC) tissues and its correlation with clinicopathologic characteristics and postoperative recurrence of primary UTUC. METHODS In a retrospective design, a total of 687 patients who underwent surgeries for primary UTUC in the urology department of Peking University First Hospital were enrolled. The methylation status of the RASSF1A gene promoter was analyzed using methylation-sensitive polymerase chain reaction on tumor specimens. RESULTS Aberrant methylation for the RASSF1A gene promoter was detected in 183 (26.6%) DNA samples in total. Aberrant methylation of the RASSF1A gene was strongly associated with tobacco consumption (P=0.044), ipsilateral hydronephrosis (P<0.001 ), tumor location (P<0.001 ), tumor stage (P=0.001), tumor grade (P=0.007), lymph node metastasis (P=0.001) and growth pattern (P=0.013). The methylated RASSF1A gene promoter was an independent risk factor for bladder recurrence (P<0.001, HR=0.471) and contralateral recurrence (P=0.030, HR=0.269) of UTUC after surgery. Hypermethylated RASSF1A was predictive for improved bladder recurrence-free survival (BRFS) (P<0.001) and contralateral recurrence-free survival (CRFS) (P=0.021) in the UTUC patients. Compared with the patients with unmethylated RASSF1A, the patients containing tumors with hypermethylated RASSF1A had tendency toward longer recurrence-free survival time [(114.4±3.9) months vs. (84.0±3.2) months for BRFS, (138.1±1.8) months vs. (132.9±1.9) months for CRFS] and higher estimated cumulative recurrence-free survive rates ( five-year survival rate for example, 79.8%±3.4% vs. 57.4%±2.6% for BRFS, 98.9%±0.8% vs. 93.0%±1.4% for CRFS). Additionally, tumor multifocality (P=0.002, HR=1.538), and ureteroscopy before surgery (P=0.001, HR=1.725) were independent risk factors for bladder recurrence in postoperative UTUC patients. CONCLUSION The methylation status of the RASSF1A gene promoter appears to be a promising epigenomic biomarker for assessing the aggressiveness of UTUC and a predictor predicting the urinary tract recurrence after surgery.

OBJECTIVE To investigate the clinical characteristics, treatment and prognosis of primary penoscrotal extra-mammary Paget's disease (PSPD). METHODS The clinical and pathological data of 22 cases of primary PSPD were retrospectively reviewed. Survival rate of the overall patients, the invasive patients, and the patients with positive surgical margin or negative surgical margin were analyzed with Kaplan-Meier survival curve method. RESULTS Among all the patients with primary PSPD, the median age of onset was 64.5 (39-84) years, the median time of disease duration was 40 (2-300) months, and the median long diameter of lesion was 4.75 (1-10) cm. In the study, 12 patients (54.5%) were in pathological stage A1, 6 patients (27.3%) were in pathological stage A2, and 4 patients (18.2%) were in pathological stage B. Scrotum and penile of most patients (n=12, 54.5%) were involved, 5 patients (22.7%) were scrotum only, and 5 patients (22.7%) were penile only. Erythema (n=18, 81.8%), itchiness (n=16, 72.7%), ulcerate (n=12, 54.5%), exudation (n=11, 50.0%), and pain (n=4, 18.2%) were the major manifestations. All the patients with primary PSPD were treated with wide surgical excision. The rate of invasive patients was 77.3% (n=17). Of them, 6 patients had positive surgical margin. The surgical margins of non-invasive patients were all negative. Twelve patients exhibited local recurrence or/and metastases, and the status of surgical margins (P=0.015) and the depth of invasion (P=0.010) were important risk factors. Inguinal lymph nodes were generally involved. The difference of the delay of diagnosis between metastasis and non-metastasis was significant (P=0.040). The 5-year survival rates of the overall and invasive patients were 33.7% and 27.9%, respectively. The patients with positive surgical margin had poor prognosis. CONCLUSION Primary PSPD, with the characteristics of long duration, high invasive tendency and high incidence of local recurrence or metastases, generally occurs in the elderly. Surgery should be performed at first. The delay of diagnosis, positive surgical margins and the involvement of inguinal lymph node are important risk factors. Biopsy, frozen section and inguinal lymph node biopsy (ILNB) can standardize diagnosis and treatment.

Abstract
Quercetin, a dietary flavonoid abundant in fruits, vegetables, and herbs, presents various pharmacological effects. This study aimed to investigate the anti-inflammatory effect and the underlying mechanism of quercetin in lipopolysaccharide (LPS)-stimulated human peripheral blood mononuclear cells (PBMCs). Cell viability was measured by the Cell Counting Kit-8 assay. The mRNA expression of Toll-like receptor 2 (TLR2) was assessed by quantitative real-time polymerase chain reaction. Inflammatory cytokine secretions and nuclear factor (NF)-kB levels were analyzed by enzyme-linked immunosorbent assay. Our findings showed that quercetin significantly reduced LPS-induced cytotoxicity in human PBMCs. Quercetin suppressed the secretion of tumor necrosis factor-a, interleukin (IL)-1b, and IL-6 in LPS-stimulated human PBMCs. Moreover, quercetin reduced the LPS-induced increase in the expression of TLR2 mRNA and decreased the NF-kB concentration in LPS-stimulated human PBMCs. The data indicates that quercetin plays an important role in LPS-induced inflammation in human PBMCs via suppression of the TLR2-NF-kB pathway.

Abstract
OBJECTIVE To evaluate the influencing factors of type 2 diabetes mellitus in Chinese, and provide evidence for developing health promotion policy in the future. METHODS Relevant studies published from January 1997 to May 2015 were retrieved from PubMed, Medline, EBSCO, Science Direct, CBM, CNKI, VIP, and Wanfang Database. Quality evaluation of the included literatures was conducted according to the inclusion and exclusion criteria, followed by data extraction and Meta-analysis with software RevMan 4.4.2. RESULTS A total of 29 studies involving 92 970 subjects(11 150 cases and 81 820 controls)were included. The pooled OR and its 95% CI of each influencing factor were: overweight OR=1.66(1.49-1.85), abdominal obesity OR=1.98(1.31-3.01), family history of diabetes OR =3.13(2.52-3.87), smoking OR=1.46(1.24-1.72), drinking OR=1.19(1.09-1.29), hypertension OR=2.64(2.23-3.13), systolic blood pressure(SBP)OR=1.15(1.06-1.24), hyperlipoidemia OR=2.26(1.75-2.92), total cholesterol(TC)OR=1.87(1.14-3.08), triglyceride(TG)OR=1.73(1.23-2.44), history of coronary heart disease(CHD)OR=2.55(1.78-3.65), cerebrovascular accident(CVA)OR=2.21(1.62-3.02), dietary fat OR=0.52(0.27-0.99). The results of subgroup analysis identified 4 common influencing factors shared by the three subgroups, i.e. overweight, family history of diabetes, smoking and hypertension. CONCLUSION Overweight, abdominal obesity, family history of diabetes, smoking, drinking, hypertension, SBP, TC, TG, history of CHD, history of CVA, and subtypes of dietary fat are the influencing factors for type 2 diabetes mellitus in Chinese. Among these factors, overweight in recent 20 years, family history of diabetes, smoking and hypertension are persistent factors. More attention should be paid to overweight and obesity.

Abstract
OBJECTIVE Carcinoma of bladder is the most common malignancy in the urinary system in China. Most patients with this disease had non-muscle invasive bladder cancer (NMIBC) at the time of diagnosis. Radical cystectomy was indicated for patients with high risk or refractory NMIBC. We aimed to investigate the overall survival and disease-specific survival and related influence factors in patients undergoing radical cystectomy for pathological non-muscle invasive bladder cancer. METHODS From Jan. 2006 to Dec. 2012, a total of 164 patients with pathological non-muscle invasive bladder cancer underwent radical cystectomy in Peking University First Hospital. Clinical data were retrospectively collected.Incidence of lymph node metastasis and disease recurrence were calculated. The risk factors of disease recurrence were analyzed. Kaplan-Meier plots were used to estimate the overall survival and cancer-specific survival. Multivariate Cox regression analysis was used to evaluate the prognostic factors for survival. RESULTS Of all the patients included, 159 had T1 disease, and 5 had CIS only. The median follow-up duration was 46.5 months (range: 7-99 months). Fourteen patients were lost during the follow-up. Lymph node metastasis was noted in 6 patients (3.7%), 4 patients had N1 disease, one patient had N2 disease, and one patient had N3 disease. Disease recurrence occurred in 16 patients (9.8%).The most common recurrence sites were the liver, bones, and lungs. The 5-year overall survival and disease-specific survival for all the patients were 85% and 91%, respectively. The patients who underwent pelvic lymph node dissection showed a better prognosis in terms of disease-specific survival than those without (P=0.012). Patients with recurrence harbored a significant poorer survival (P<0.001). According to univariate Cox regression analysis, whether lymph node dissection was performed was an independent risk factor of disease recurrence (P=0.050, OR=2.695, 95%CI 0.999-7.271). In COX regression model, age (P=0.008, OR=1.071, 95%CI 1.018-1.126) and whether lymph node dissection was performed (P=0.011, OR=3.385, 95%CI 1.329-8.621) were related to disease-specific survival. CONCLUSION Patients with pathological non-muscle invasive bladder cancer underwent early radical cystectomy have a favorable prognosis, and bilateral pelvic lymph node dissection is essential for this procedure as it gains a survival benefit for the patients.

Abstract
OBJECTIVE To discuss the therapy for ureteral endometriosis. METHODS The clinical data of 25 cases of histopathologically confirmed ureteral endometriosis during 2001-2015 were retrospectively analyxed. RESULTS In the 25 cases, all the patients took urinary ultrasound for examination before surgery, of whom 21 (84%) were examined by CT and 5 (20%) by MRI. Three (12%) cases underwent preoperative KUB and intravenous pyelogram (IVP) examination. Four (16%) cases were examined by retrograde pyelography before surgery. Eight (32%) of them took cystoscope for examination and 11 (44%) took preoperative radionuclide renal dynamic imaging examination. All of these cases were affected with unilateral ureter, 13 (52%) in the right and 12 (48%) in the left. The ureter lesions were at the upper part in 21 (84%) cases and at the middle part in 4 (16%) cases. In these cases, 11 (44%) received partial ureteral resection and end-to-end ureteral anastomosis, 10 (40%) received partial ureteral resection and ureterocystoneostomy, 3 (12%) received retroperitoneal laparoscopic nephroureterectomy, and 1 (4%) received endoscopic resection of ureteral endometriosis lesion. All of these cases were confirmed with ureteral endometriosis by post-surgery pathology results, with the expression of CA125 and ER in the glandular tissue and expression of PR in the mesenchymal tissue inside the ureteral muscle detected by immunohistochemistry. Four (16%) cases took postoperative adjuvant hormonal therapy. And no recurrence was found among 16 (64%) cases with the successful follow-up which ranged from 3 to 76 months and the median follow up was 28 months. Fifteen cases were submitted to the follow-up by urinary ultrasound (93.8%) and 5 (31.3%) underwent CT for examination. All the cases relieved from hydronephrosis, and symptoms of 10 (63.5) cases disappeared. The cases with double-J stent all had the stent removed within 3 to 6 weeks. CONCLUSION Surgical procedures should be considered as the main therapy for ureteral endometriosis. We recommend ureterolysis for patients with mild ureteral obstruction and hydronephrosis. As for those with moderate and severe ureteral obstruction and hydronephrosis, we recommend partial ureteral resection. When the situation comes to patients with little renal function of the affected side, the recommended management is nephroureterectomy.
