Objective To evaluate the domestic made penile prosthesis for the management of erectile dysfunction. Methods The domestic made three piece inflatable prosthesis has been implanted to 20 ED patients from 1997 to 2001. Results The overall complication rate was 20% (4/20), nonmechanical in 4 (20%) and there has been no mechanical complication.Infection after operation occurred in 1 case (5%). The penile prosthesis penetrated out in 3(15%). Conclusions The mechanical function and concealment have been significantly improved with the domestic made three piece inflatable penile prosthesis.

Objective To present the experience of diagnosis and treatment of 21 cases of retrocaval ureter. Methods 21 cases of retrocaval ureter were retrospectively analysed. Results The main clinical symptom was right waist pain in 20 cases,4 of them with typical renal colic.8 cases had gross hematuria and calculus in the renal pelvis.1 case was void of symptom.The diagnosis of the disease depended mainly on intravenous urography (IVU) and retrograde ureteropyelography (RGU).IVU and RGU showed a "S" shaped upper ureteral segment with dilatation. Ureteral replacement and ureteroplasty were carried out in 20 cases which have been followed up from 2 months to 28 years with an average of 13 years.The symptom disappeared in 19 cases,with hydronephrosis and hydroureter significantly reduced on IVU and ultrasonography.1 case underwent ureteral reanastomosis because of stenosis at anastomosis site. Conclusions In patients with hydronephrosis and hydroureterosis of upper segment on the right side,the possibility of retrocaval ureter should be considered.Intravenous urography and retrograde ureteropyelography are the main means of diagnosis.Ureteral replacement and ureteroplasty are the treatment of choice.

Objective To study the diagnosis and treatment of spontaneous perirenal hemorrhage(SPH). Methods The clinical data of 31 cases of SPH were reviewed retrospectively.In the 31 cases,flank pain,flank mass,shock,gross hematuria,abdominal bleeding occured in 31,10,8,3 and 3 cases,respectively.The final diagnosis was established on CT scan,B-ultrasonography and IVU were 18,22 and 7 cases. Results In 31 cases,nephrectomy were performed in 18,radical nephrectomy in 1 case,nephron spare surgery in 4,renal artery embolization in 2,inspiration and drainage of hemorrage in 1 and careful watching in 5 cases.There were 11 cases of angiomyolipoma,6 renal cyst,4 of renal cell carcinoma,3 infectious diseases,2 aneurysm of renal artery and 2 hydronephrosis. Conclusions The clinical presentation may vary greatly depending on the degree and duration of bleeding,and the severe pain in the upper abdomen of abrupt onset is the common sign and symptom.The spontaneous rupture of renal cell carcinoma and angiomyolipoma are the most common cause of SPH.CT scan and B-ultrasonography are the most valuable in the diagnosis of SPH.It is demanded that management of SPH depends on the histopathology and the degree of bleeding.

Objective To investigate the morphological changes of peritoneum during peritoneal dialysis (PD) and elucidate the possible mechanism of its functional deterioration. Methods Peritoneal biopsies were obtained from normal subjects( n = 10), uremic predialysis patients( n = 12) at catheter insertion and PD patients ( n = 10) at the time of catheter remove or reinsertion or renal transplantation, peritoneal morphology was studied by light microscopy, scanning electron microscopy and transmission electron microscopy. Results Normal peritoneal membrane consisted of a monolayer of mesothelial cells on a basement membrane, and a layer of connective tissue containing cells, blood vessels, lymphatic vessels and so on. Mesothelial cells were polygonal, often elongated, and had numerous microvilli on their luminal surface. Sometimes the microvilli ended with roundish formation or resembled a corona. There were lots of oval or roundish pinocytotic vesicles in the cytoplasm of mesothelial cell. Submesothelial connective tissue contained many collagen and elastic fibers. The peritoneal morphology of uremic predialysis patients was similar to that of normal subjects. But significant abnormalities of peritoneal morphology were observed in PD patients and the changes were progressive. Microvilli were the first site of damage, including microvilli shortening, gradual reduction in number and following total disappearance. Then mesolhelial cell detachment from basement membrane and total disappearances were found. Finally the peritoneal membrane only consisted of submesothelial connective tissue denudation of cells. Conclusions PD can modify peritoneal morphology and structure. The morphological change is progressive and might be one of the important causes of peritoneal failure. Peritoneal biopsy can provide lots of valuable informations about the impact of PD, and thus further study on the relationship between peritoneal structure and its function is very useful for understanding of the physiopathology of peritoneum during PD.

RT-PCR and in situ hybridization were observed during dialyzer reuse. Results Every plasma cytokine level was decreased during reuse compared with first use dialyzer, but no significant difference was found between them. The levels of gene expression of IL-1?、TNF-? and IL-6 were different from the first use significantly. Conclusion If effective dialysis volumn was maintained, formaldehyde as disinfectant on reprocessing the dialyzer may amilorate membrane bio-compatibility. It would be benificial to decrease appearance of long term hemodialysis -related complications.

To determine whether uremia per se can activate peripheral blood mononuclear cells (PBMCs). Methods Maintained hemodialysis patients with cuprophane, non-dialysis uremic patients and healthy volunteers were selected to investigate IL-1?、 TNF-? and 11,6 mRNA in PBMCs by RT-PCR and cells in situ hybridization. Results IL-1?,TNF-? and IL-6 mRNA in PBMCs were undetected in healthy volunteers, but these cytokine gene expression were detected in hemodialysis patients and non-dialysis uremic patients. IL-1?、TNF-? and IL-6 mRNA level was lower in non-dialysis uremic patients than that in hemodialysis patients. Conclusion Uremia per se or its related factors may activated PBMCs and the preactivation of PBMCs might be associated with the body resistance against infection in uremic patients.

OBJECTIVE:To provide reference for the establishment of clinical skills evaluation system in students majored in clinical pharmacy and pharmacy of China. METHODS:Retrieved from pharmacy OSCE literatures and the related websites,phar-macy OSCE contents and evaluation in the United States,the United Kingdom,Canada,Japan,Malaysia and other countries were introduced to provide suggestions for clinical skills evaluation system in students majored in clinical pharmacy and pharmacy of Chi-na. RESULTS & CONCLUSIONS:OSCE had widely applied in medicine,nursing and other professional clinical skills,the United States,the United Kingdom and other countries had applied OSCE into pharmacy,and confirmed its important role in assessment of clinical competence in pharmacy students. There was no uniform standard in OSCE,and OSCE examinations were slightly different in different countries and different schools. Pharmacy OSCE usually based on school courses such as pharmacotherapy,clinical pharmacokinetics,medicine information,pharmaceutical care,doctor-patient communication,identification and solving ability of clinical drug-related issues. Numerous college of pharmacy in domestic colleges and universities has added the practice-based cours-es,but evaluation system and assessment methods are poor. Almost no OSCE is applied for the assessment of pharmacy students. OSCE has short application time in pharmacy education and relatively less study,therefore,pharmacy OSCE in foreign countries should be learnt to assess clinical skills of pharmacy students,establish and improve the pharmacy OSCE that is suitable for China by combining with the pharmacy education status.
