Prostate cancer, bladder cancer, and rectal cancer are common malignancies in the male pelvis. The incidence rate of erectile dysfunction (ED) following radical prostatectomy, cystectomy or rectal cancer surgery is about 25% - 100%. The main cause of post-surgery ED is mainly attributed to injury of neurovascular bundles, which may lead to reduced oxygenation in and fibrosis of the penile tissue. Early penile rehabilitation after surgery can improve or restore the erectile function of the patients. This article focuses on penile rehabilitation after radical pelvic surgery.

Objective To investigate the effects of maternal long-term exposure to low-dose trichlorfon on the serum paraoxonase (PON) activity of pregnant mice and development of embryos. Methods Female ICR mice (n=120) were randomly divided into control group and trichlorfon groups of different doses,and were managed by intragastric injection with trichlorfon of 0,2,10 and 50mg/kg,respectively. All the mice were managed once a day for a consecutive of 27 days,and were subjected to mating. The pregnant mice were continued to be managed with trichlorfon for 3 days,and were sacrificed on day 3 of gestation. The serum PON and acetylcholinesterase (AchE) activities were detected,and the development of embryos was evaluated. Results The serum PON activity of 2,10 and 50mg/kg trichlorfon group were (14.15?1.22),(12.78?1.80) and (10.45?1.95)IU/mL,respectively,and that of 50mg/kg trichlorfon group was significantly lower than that of control group [(13.37?2.31)IU/mL] (P0.05),while the the percentage of abnormal embryos of 50mg/kg trichlorfon group had an increased tendency. Conclusion Long-term exposure to low-dose trichlorfon can inhibit serum PON and AchE activity in pregnant mice without obvious effect on the development of embryos.

Objective To evaluate the long-term outcome of acute kidney injury (AKI) during hospitalization after cardiac surgery.Methods 1 770 patients underwent cardiac surgery in Fudan University Zhongshan Hospital from April 2009 to February 2011 were enrolled.Based on the Kidney Disease:Improving Global Outcomes (KDIGO) guideline of AKI,the patients were divided into the AKI and the nonAKI groups,and followed up for 2 years.The 2-year survival rate and incidence of the advanced chronic kidney disease (CKD) was compared between the two groups.Factors influencing the 2-year survival rate and incidence of the advanced CKD were also analyzed.Results Among all the patients,715 (40.4%) of them were developed AKT.(1) The 2-year survival rate of the AKI group was lower than that of the non-AKI group (83.2% vs 93.6% ;P <0.05).Compared with the non-AKI group,AKI group had an increased risk for death with the hazard ratio of 1.710 (95% CI 1.250-2.340).COX regression analysis showed that AKI was an independent factor for death with the risk intensity just less than diabetes and chronic cardiac insufficiency.The advanced age,the preoperative history of chronic cardiac insufficiency and the time of staying in ICU also significantly increased the risk of death.(2) Compared with patients without AKI (0.2 %),the incidence of the 2-year of advanced CKD was higher in patients with AKI (6.7 % ; P < 0.05) with an hazard ratio of 31.220 (95 % CI 7.550-129.110).COX regression analysis showed that AKI was still the independent risk factor for advanced CKD after adjustment of other factors.In addition,diabetes,the time of the cardiopulmonary bypass and the time of staying in ICU were also associated with the risk for the advanced CKD.Conclusions AKI is common after cardiac surgery,which was associated with a decrease in the 2-year survival rate and an increase in the incidence of advanced CKD of patients,which emphasized the importance of prevention and treatment of AKI,and close follow-up of renal function for the improvement of patient long-term prognosis.

Objective To investigate the situation of prevalence,treatment and control of hypertension in patients with chronic kidney disease(CKD)by CROSS-sectional study. Methods Nine hundred out-patients with CKD in our department from November 2006 to March 2007 were enrolled in the study,including 480 male and 420 female.Among 900 CKD cases,354 patients underwent maintenance dialysis,including 228 on hemodialysis and 126 on peritoneal dialysis.Results The prevalence of hypertension in CKD patients was 80.2%(nude 83.5%vs female 76.4%,P<0.01).The prevalence of hypertension in patients on dialysis was significantly higher than that in non-dialysis patients(90.1%vs 73.8%,P<0.01),but there was no significant difference between hemodialysis and peritoneal dialysis cases.Antihypertensive treatment rate was 92.4%in CKD patients with hypertension.and was significantly higher in patients on dialysis than that in non-dialysis patients(95.6%vs 89.8%.P<0.01).The control rate according to current recommendations for CKD patients (BP<130/80 mm Hg) was very low. Control of both SBP and DBP was only achieved in 20.4% of non- dialysis patients. The control rate of hypertension (BP< 125/75 mm Hg) in patients with proteinuria >1 g/24 h was 8.4%. The proportion of dialysis patients with BP<140/90 mm Hg was significantly lower than that of non-dialysis patients (45.2% vs 55.5%, P<0.01). The percentage of hemodialysis patients with BP < 140/90 mm Hg was significantly higher than that of peritoneal dialysis patients (49.8% vs 36.5%, P<0.05). The prevalence of hypertension was associated with the decrease of renal function and the increase of age. The prevalence of hypertension in diabetic nephropathy was higher than that in primary glomerular diseases. Patients received 1, 2, 3 and 4 or more kinds of antihypertensive drugs accounted for 37.2%, 37.5%, 19.3% and 5.9% respectively. The combination of calcium channel blocker (CCB) and renin-angiotensin-aldosterone system (RAAS) inhibitors was more frequently used in CKD patients. The CCB was the most frequently prescribed drug (74.1% ), followed by angiotensin Ⅱ receptor blockers (ARB) (48.4%), angiotensin-converting enzyme inhibitors (ACEI) (25.6%) and alpha, beta-blockers (24.7%). Conclusions The prevalence of hypertension in CKD patients is quite high, which is associated with the progression of renal function, increase of age, the type of underlying kidney disease, obesity and diabetes mellitus. The control of hypertension is unsatisfied in CKD patients, especially in dialysis patients and those with overt proteinuria.

ObjectiveTo compare the efficacy and safety of intermittent patient-initiated single-dose antibiotic prophylaxis and continuous antibiotic prophylaxis for the prevention of recurrent urinary tract infection (UTI) in postmenopausal women. MethodsA randomized controlled clinical trial was conducted for the prevention of recurrent urinary tract infection. Single dose of antibiotic was given every night in continuous antibiotic prophylaxis group and every time after exposure to conditions predisposed to UTI in intermittent antibiotic prophylaxis group. The duration of prevention was 12 months in both groups. ResultsThe effective rates of intermittent antibiotic prophylaxis and continuous antibiotic prophylaxis were 71.0% and 81.8% respectively (P>0.05). The incidence of gastrointestinal adverse reaction in intermittent antibiotic prophylaxis group was significantly lower than that in continuous antibiotic prophylaxis group (7.7% vs 28.6%,P<0.05). ConclusionsCompared with continuous antibiotic prophylaxis, intermittent patient-initiated single-dose antibiotic prophylaxis is a better prophylaxis with less gastrointestinal adverse reactions for the prevention of recurrent urinary tract infection in postmenopausal women.

Objective To study the efficacy of low-dose daytime ambulatory peritoneal dialysis (DAPD) and low-dose CAPD in diabetic end-stage renal disease (ESRD) patients with better residual renal function (RRF). Methods Forty stable diabetic ESRD patients with better RRF (rGFR ≥ 5 ml/min and urine volume ≥ 750 ml/d) were enrolled. They were randomly divided into two groups: low-dose DAPD group (n=20) and low-dose CAPD group (n=20). DAPD group received three 1.5 L to 2 L daily exchanges with a nocturnal empty belly, dwelling for 3 to 4 hours. CAPD group received three 1.5 L to 2 L daily exchange or four 1.5 L daily exchange regimens and dwelled during the night. At the beginning of the study and 6 months later, total weekly Kt/V and Ccr (peritoneal+renal), rGFR were calculated. Meanwhile 24-hour urinary protein,serum albumin (Alb), hemoglobin (Hb), fasting plasma glucose, glycosylated hemoglobin and insulin dosage were measured. Nutritional status was assessed by SGA. Results Thirty-five patients fulfilled the study. There were no significant differences between two groups in age, gender, BMI,PD time, D/Pcr, etc. At the end of the 6th month, the insulin dose[(33.6±10.9) U/d] and 24-hour dialysate protein [(11.13t4.95) g] in CAPD group were significantly higher as compared to DAPD group [(20.6±6.2) U/d, P<0.05 and (5.66±2.88) g, P<0.01 respectively]. Alb in CAPD group [(29.7±4.2) g/L] was significantly lower than that in DAPD group [(36.5 ±3.9) g/L, P<0.05].While the net ultrafiltration [(554±187) ml vs (309±177) ml], 24-hour urine volume [(1090±361)ml vs (750±258) ml] and rGFR [(8.21±2.40) ml/min vs (4.88±2.11) ml/min] in DAPD group were all significantly higher than those in CAPD group (all P<0.05). Conclusion For the diabetic ESRD patients with better RRF, the low-dose DAPD regimen is more effective to control plasma glucose, improve nutritional status and protect RRF than the low-dose CAPD.
