The golden standard for the treatment of invasive bladder cancer is radical cystectomy. However its application is limited in certain circumstances because of surgical trauma,complications,and impacts on quality of life. As organ preservation protocols have become the standard in the treatment of some malignancies such as breast cancer、anal cancer、esophageal cancer,the multimodality treatment with bladder preservation was introduced to cure invasive bladder cancer, which can retain normal bladder function without a marked compromise of overall survival and is a viable, reasonable alternative for the treatment of invasive bladder cancer. This review highlights the advances in multimodality treatment with bladder preservation for invasive bladder cancer.

The competence of scientific research ethnical review in domestic hospital was inadequate,which was associated with the development of medical ethnics,values of Chinese traditional society,unsound domestic laws and regulations,weak administrative management,unqualified committee of medical ethnics,the drive of scientific deriving interests and restriction of project funds.Aiming at the above problems,countermeasures were carried out to strengthen the construction of laws and regulations,strengthen the constraint of administrative management,standardize the self-construction of ethnic committee,implement the standard operative procedure,thus to provide a reference for the standardized construction of scientific research ethnical review.

Objective To observe the effects of extracorporeal membrane oxygenation (ECMO) on coagulation during lung trangplantation.Method Forty cases of end stage lung diseases received bilateral sequential single lung transplantation during July 2007 and Mar.2012.The patients were divided into two groups in terms of ECMO.ECMO was applied before lung transplantation if needed.The amount of bleeding during surgery was recorded.The venous blood samples were collected during and after operation for the measurements of the following parameters:activated whole blood clot time (ACT),prothrombin time (PT),activated partial thromboplastin time (APTT),thrombin time (TT) and plasma fibrinogen (Fg).Result The coagulation and the amount of bleeding showed no significant difference between the two groups.Wound infection occurred in 2 patients where the ECMO tube was inserted and femoral arterial thrombosis in one patient.All of the three patients were cured and discharged.Conclusion ECMO didn't cause excessive bleeding or coagulation dysfunction during lung transplantation,yet it maybe increase the occurrence of local thrombosis.

Objective To construct a nomogram for estimating disease free survival of node-positive penile cancer treated with surgery.MethodsThe clinicopathological data of 32 node-positive penile squamous cell carcinoma patients were retrospectively reviewed.All patients had undergone primary tumor excision and regional lymphadenectomy.The pathological records showed that 10 were N1,13 were N2 and 9 were N3.Median level of preoperative squamous cell carcinoma antigen (SCCAg) was O.9 μg/L.With a median follow-up of 16.5 months,13 patients developed recurrence.Based on the stage,histological grade and preoperative serum squamous cell carcinoma antigen level,a nomogram was drawn on the basis of the Cox regression model.Results Stage and preoperative serum SCCAg levels were independent prognostic factors for disease free survival in node-positive penile cancer treated with surgery.The hazard ratio of SCCAg level and N stage was 2.76 (95％ CI:1.40-5.44,P=0.0034) and 28.51 (95％ CI:2.55 -319.11,P =0.0066).The nomogram demonstarted good discrimination and calibration with a concordance index of 0.855.Conclusions Based on the N stage and preoperative serum SCCAg level,a nomogram to predict disease free survival in node-positive penile cancer treated with surgery was set up.The prediction model could be helpful in predicting the risk of recurrence.

Objective To evaluate the prognostic value of bilateral inguinal lymph node metastases in node-positive penile cancer. Methods Sixty patients with surgically resected node-positive penile cancer were analyzed. All the patients underwent regional lymph node dissection. Recurrence free survival curves were plotted by Kaplan-Meier method and compared by the Log-rank test. Multivariate survival analysis was performed using Cox regression model. Results Of all the patients, 18 cases had bilateral inguinal lymph node metastases. The 3-year recurrence free survival rate in patients with bilateral invovlement was significantly lower than those with unilateral disease (26.7 % vs 65.3 %, χ2 =10.6, P=0.001). In order to evaluate wether the prognostic significance of bilateral lymph node metastases was dependent of increased number of positive nodes, the two predictors were included in multivariate survival analysis.Both the number of metastatic nodes and bilateral nodal disease were independent prognostic factors (P ＜0.05).Comparisons of survival curves showed those patients with bilateral nodal disease and more than 2 metastatic nodes had worst outcome. Conclusion Bilateral inguinal lymph node metastases is an important prognostic factor in penile cancer irrespective of the number of positive lymph node.

Objective To discuss the benefits of extracorporeal membrane oxygenation (ECMO) applied in the patients with primary or secondary pulmonary hypertension during the operation of lung transplantation. Methods Thirty cases of end stage lung disease subject to primary or secondary pulmonary hypertension received lung transplantation supported with ECMO between Nov. 2005 and July 2009. The single lung transplantation was performed on 18 cases and bilateral sequential single lung transplantation on 12 cases. ECMO was used in 2 patients as a bridge to the lung transplantation to maintain 19 and 6 days respectively, and ECMO support was given during lung transplantation. ECMO was removed after the transplantation if the oxygenation and hemodynamics were stable, otherwise, ECMO was applied continuously until the situation improved. Results All the operations of these patients were accomplished successfully and the ECMO was removed in 27 patients after the operation immediately. The average time with ECMO was 6. 81 + 0. 95 h, and pulmonary artery systolic pressure after lung transplantation was 31.67 + 8. 42 mmHg. The ECMO was continuously used after lung transplantation in three patients until the hemodynamics was stable, and ECMO in 2 of them was removed at 36th h and 6th day respectively after the operation, and one,receiving postoperative ECMO for 5 days, died of acute renal failure 2 weeks after the operation.Conclusion ECMO can replace CPB safely and effectively in lung transplantations for primary or secondary pulmonary hypertension patients. As a respiratory and circulatory support it can control pulmonary hypertension during operative period and can decrease the complications of lung transplantation.

Objective To construct and evaluate a nomogram for predicting the risk of regional lymph node metastases according to pathological features of the primary penile squamous cell carcinoma. Methods The clinical and pathological data of 73 patients who had undergone partial/radical penectomy and ilio/inguinal lymphadenectomy for squamous cell carcinoma of the penis from 1990 to 2005 were retrospectively collected. The expressions of molecular markers (p53, Ki-67, E-cadherin and MMP-9) were determined by immunohistochemistry. A logistic regression model was used to construct the nomogram. Results Tumor grade, the expression level of p53 and lymphovascular invasion were independent prognostic factors of regional lymph node involvement (P<0. 05). The nomogram predicting the risk of metastatic lymph node involvement showed a good concordance index (0. 92) and good calibration. Conclusions Based on the pathological findings of primary tumor, a nomogram to predict the probability of regional lymph node involvement in penile squamous cell carcinoma patients is constructed. This statistical tool is not only helpful in judging individualizing tumor risk, but also in facilitating patients communication in treatment options.

Objective:This study aimed to detect the special methylation profile in peripheral blood for hepatocellular carcinoma (HCC). Methods:The methylation status of 12 tumor suppressor genes (TSGs) in the plasma of 55 HCCs and 54 chronic liver diseases (CLDs) was tested by methylation-specific PCR (MSP). Results:In HCC, the methylation frequencies were 78.18%in APC, 63.64%in cyclin D2, 58.18% in TFPI2, 49.09% in DKK3, 49.09% in GSTP1, 47.27% in p16, 40.00% in Sigma 14-3-3, 18.18% in SFRP2, 16.36% in ppENK, 9.09% in DKK2, 7.27% in NPTX2, and 5.45% in LHX1. In CLD, the methylation frequencies were 27.78% in APC, 22.22%in cyclin D2, 7.41%in TFPI2, 3.70%in DKK3, 16.67%in GSTP1, 37.04%in p16, 37.04%in Sigma 14-3-3, 11.11%in SFRP2, 20.37%in ppENK, 7.41%in DKK2, 7.41%in NPTX2, and 9.26%in LHX1. The methylation frequencies of APC, cyclin D2, TFPI2, DKK3, and GSTP1 were higher in HCC than in CLD (P<0.01). The methylation index (MI) of the five-gene methylation profile was statistically higher in HCC (median, 0.6;IQR, 0.4-0.8) than CLD (median, 0.2;IQR, 0-0.2) (P<0.01). In HCC, MI was statistically related to the patient's age. Older patients with HCC had a higher MI. No significant correlation was observed between MI and other clinicopathological data. Moreover, MI was not related to the disease free survival and the overall survival in HCC. Conclusion:This five-gene methylation profile may be a promising biomarker for the assistant diagnosis of HCC.

Background and purpose:Liquid biopsy is a kind of blood, urine and other non-solid biologi-cal tissue sampling analysis, mainly for malignant tumor diagnosis, monitoring and predicting its prognosis. In this research, we optimized the extraction of miRNA in urine, established a standardized means of liquid biopsy, screened and verified the miRNA markers in patients with bladder cancer.Methods:From Jan. 2014 to Sept. 2015, we used miRNA microarray in six patients with bladder cancer and six healthy controls. Samples of 78 cases of bladder cancer and 23 healthy controls were tested by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) to verify the relationship between miRNA markers in liquid biopsy and clinical pathological parameters. The diagnostic value of miRNA markers was also analyzed and compared.Results:We screened 10 miRNAs differential expression in urine. Combined with previous literature, we selected 20 miRNAs to verify their expression levels in bladder cancers and healthy controls. miR-509-5p/miR-124 ratio in the urine was found higher in patients with bladder cancer than in healthy controls (P<0.0001). With the rise of miR-509-5p/miR-124 ratio in urine, tumor stage and grade were also increased (P=0.003). When the cutoff was set at 0.41, the diagnostic sensitivity and specificity of miR-509-5p/miR-124 ratio were 73.1% and 82.6%, respectively. The AUC of miR-509-5p/miR-124 ratio to detect bladder cancer was 0.864, higher than that of urinary exfoliated cells (P=0.0002).Conclusion:We optimized the extraction of miRNAs in urine,established a standardized liquid biopsy of miRNA markers. The miR-509-5p/miR-124 ratio could be an ideal diagnos-tic marker for bladder cancer.

Objective:To learn the cognition and attitudes of psychometric ethics of graduate students whose major was clinical psychology or counseling psychology,and to investigate whether ethics training could influence their cognition and attitude.Methods:Researchers distributed the questionnaire online regarding cognition and attitudes of psychometric ethics among clinical and counseling psychology graduate students.Seventy-six feedbacks were collected (4 students were learning ethics courses,27 students had learned ethics courses,45 students hadnt learned ethics courses).The questionnaire included the Psychometric Cognition Questionnaire (PCQ),Situational Judgement Questionnaire (SJQ) and Psychometric Attitude Questionnaire (PAQ).The first two sets of questionnaires reflected ethics knowledge.The last one showed ethics attitudes and behavioral tendencies.Results:The correct rates in participants who had learned or were learning ethics were 76.5％ and 75.1％ at the first and second set of questionnaires,while were 73.9％ and 74.2％ in other participants.The correct rates of three major clauses in PCQ were 90.3％,67.7％ and 74.2％,significantly higher than participants who never learned ethics,whose correct rates were 88.9％,66.7％,and 44.4％ (Ps ＜ 0.05).There were no significant differences in SJQ between those who had learned or was learning ethics and those who had never learned ethics (Ps ＞0.05).Participants who had learned or were leaning ethics scored in sum in PAQ that had no significant differences with those who had never learned ethics(Ps ＞ 0.05).Conclusion:Clinical and counseling psychology graduate students master considerable level of knowledge on ethics and attitude.Ethics training is essential for acquiring psychometric ethics.
