Objective To summarize the clinical features,diagnosis and treatment of autologous urologic neoplasms in renal transplant recipients.Methods A retrospective analysis on the clinical data of 25 renal transplant recipients was done in our center.The onset time of new neoplasms was between 29 to 72 months after transplantation,with an average of 48.2 months.Intermittent hematuria was the first symptom in 23 patients,and the rest two cases were diagnosed through routine examination. The pathological diagnoses of thee cases were renal carcinoma,which were treated by transperitoneal laparoscopic radical nephrectomy.Eight cases were diagnosed as having renal pelvic tumor,which was treated by radical resection for the renal pelvic carcinoma.Fourteen cases were diagnosed as having bladder cancer,which was treated by transurethral resection of bladder tumor (13 cases) or radical cystectomy (one case).All patients were subjected to surgical treatment.The dosage of MMF,CSA/Tacrolimus was decreased to 1/2-2/3 of their original dosage. Sirolimus was used in place of calcineurin inhibitors in four patients.Immunosuppressive regimes and adjuvant therapy were given after surgery treatment.Results Twenty-five patients were followed up for 12-84 months.Contralateral renal carcinoma combined with lung and chest multiple metastases occurred in one case after radical nephrectomy,who died after targeted therapy 6 months later.Two patients with lymph node metastasis died 14 months and 20 months after surgery respectively.The rest 22 patients were closely followed up,whose creatinine remained 98-163μmol/L.Conclusion More attention should be paid to patients with hematuria after renal transplantation to screen the autologous urinary neoplasms.Patients should be treated with surgical procedures,and immunosuppressive regimens should be adjusted postoperatively.

Objective: To establish a risk assessment index system for epidemic infectious diseases in primary and secondary schools, for early warning and prevention of school infectious diseases accurately and timely. Methods: Through literature review, the indicators pool was established by consulting relevant experts and referring to practical experience. Then two rounds of expert consultation using the Delphi method were conducted(13 experts of round 1, and 20 experts of round 2). The concentration of expert opinions (the average, the percentage of full marks) and the coordination of expert opinions (the coefficient of variation, the coordination coefficient W ) were calculated and analyzed. The coordination coefficient W was obtained by nonparametric Kendall s W test of multiple samples. According to the experts feedback, necessary addition, reduction and modification of the indicators were carried out to determine the evaluation index system, and the analytic hierarchy process (AHP) was used to calculate the weight of each indicator. Results: The expert authority coefficients of the two rounds of consultation were 0.89 and 0.88, respectively, and the form recovery rate was 100%. The range of the variation coefficient of each three level indicator was 0.07-0.31 and 0.06-0.19, and the coordination coefficient W was 0.25 and 0.47, respectively, indicating that the consistency and credibility of expert opinions were good. Finally, the risk assessment index system of infectious diseases in primary and secondary schools was established, which was composed of 5 first level indexes, 23 second level indexes and 86 third level indexes. The AHP was used to calculate the intra level weight of the index. The variation coefficient of five first level indicators of school health management and security system, school health personnel facilities, health monitoring and cognition level, severity and coping measures were 0.09, 0.06, 0.08, 0.12 and 0.06 , respectively, and the weight coefficients were 20.42%, 21.19%, 19.87%, 17.45% and 21.08%, respectively. Conclusion The risk assessment index system of school infectious diseases is applicable to primary and secondary schools. The initiative, coordination and authority of experts in this system are all high. It is of practical guiding significance for the early warning of infectious diseases in primary and secondary schools.

Objective To review the clinical characteristics of prostate mucinous adenocarcinoma cases and update literatures,and recommend the corresponding clinical treatment strategy.Methods From October 2010 to March 2018,36 cases of prostate mucinous adenocarcinoma were involved from 5 urinary centers in China,including 9 cases from Shanghai Changhai Hospital,4 cases from Wuhan Tongji Hospital,13 cases from Shanghai Renji Hospitals,8 cases from the First Affiliated Hospital of Nanjing Medical University,and 2 cases from Sichuan West China Hospitals.The patients' age were (66.8 ±7.2) years (53-83 years) and the median PSA was 22.89 ng/ ml (2.67-1786 ng/ ml).Prostate biopsy confirmed Gleason score 3 + 3 points in 6 cases,3 + 4 points in 9 cases,4 + 3 points in 5 cases,8 points in 11 cases,and 9 to 10 points in 5 cases.According to D'Amico risk stratification,2 patients were in the low-risk group,9 in the intermediate-risk group,and 25 in the high-risk group.Eight cases underwent radical retroperitoneal prostatectomy,13 cases underwent laparoscopic radical prostatectomy,and 12 cases underwent robotic laparoscopic radical prostatectomy.Twenty-three cases underwent pelvic lymphadenectomy,including 12 cases of bilateral obturator lymph node dissection,and 11 cases of bilateral obturator + intraorbital + para-vascular para-aortic lymphadenectomy.Results All 36 operations were completed successfully.Twenty-three cases underwent pelvic lymphadenectomy,including 12 of bilateral obturator lymph node dissection,and 11 of bilateral obturator,intraorbital,and para-aortic lymphadenectomy.Pathological examination showed 9 cases of prostate mucinous adenocarcinoma,26 cases of mucinous adenocarcinoma with acinar adenocarcinoma,and 1 case of mucinous adenocarcinoma with neuroendocrine and immunohistochemical positive of MUC2 (+).Among 33 cases undergoing radical surgery,the pathological stage of ≤T2b in 12 cases (36.3％),T2c in 7 cases (21.2％),T3a in 7 cases (21.2％),T3b in 6 cases (18.2％),and T4 in 1 case (3.0％).Four cases had positive pelvic lymph nodes and 9 cases had positive margin.The median follow-up period was 26 months (6-48 months).The biochemical recurrence occurred in 6 patients one year after surgery,including 3 cases in the intermediaterisk group and 3 cases in the high-risk group.Six cases with postoperative biochemical recurrence and 19 cases with PSA ＞ 0.2 ng/ml after radical or palliative resection underwent adjuvant androgen deprivation therapy(ADT),no postoperative adjuvant radiotherapy or chemotherapy was administered,and 4 cases progressed to castration-resistant prostate cancer.Four cases with CRPC were in the high-risk group and had underwent radical surgery,and the median period progressed to CRPC was 26 months(3-37months)with 2 cases of death.However,there was no significant difference in the rate of biochemical recurrence and the incidence of CRPC in the low-risk group,the intermediate-risk group and the high-risk group.In addition,2 cases had metastases,with pelvic MRI presenting pelvic multiple nodular mass in one case which was consistent with recurrence and metastasis at the 5th month after radical surgery,and pathological examination presenting the mucinous adenocarcinoma being neurosecretory in another case and mestastasis being detected on glans at the 3rd months after radical surgery.The recovery rate of urinary continience at 6 and 12 months after radical surgery was 86.2％ (31/36) and 89.7％ (32/36) respectively.Conclusions Prostate mucinous adenocarcinoma is a variant of acinar adenocarcinoma.This study clarifies prostate mucinous adenocarcinoma of Chinese patients with high Gleason scores,advanced pathological stage,variant in prognosis,and prone to recurrence and metastasis.For treatment strategy,the low-risk and intermediate-risk mucinous adenocarcinoma is recommended undergoing radical surgery,and the prognosis maybe good.High-risk mucinous adenocarcinoma could treated with radical surgery or palliative surgery with adjuvant ADT,and most high-risk patients can benefite,with a small number of poor prognosis.
