OBJECTIVETo investigate the long-time effects of nylon fixation at the internal and external canthus combined with skin graft for recurrent lower eyelids ectropion.

METHODSUnder local anesthesia, the cicatricial contraction was released to repostion the lower eyelid. Then nylon thread was implanted in the fascial tissue at the upper margin of tarsus and was fixed on the periosteum at the internal and external canthus. The skin graft was applied on the wound of lower eyelids.

RESULTS12 patients with lower eyelids ectropion at 19 sides were treated with primary healing. The patients were followed up for 6-24 months. All cases were satisfied with functional and cosmetic results. No complication and no recurrence happened.

CONCLUSIONSThe technique of nylon fixation at the internal and external canthus combined with skin graft is an effective method for recurrent lower eyelids ectropion.

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.

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 study the extraction method of total flavonoids in Mosla hangzhowensis Matsuda.Methods:Orthogonal experiment design was used,with the content of the total flavonoids as the index,to study the effect of ethanol concentration,solvent quantity and extraction time on recovery rate of total flavonoids.Results:The best extraction condition was:extract two times;adding 20 fold 65% ethanol and to extract an hour each time.Conclusion:This extraction method is convenient and feasible.

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.

ObjectiveTo present 4 cases of primary c ar cinoid tumor of urinary bladder and to discuss the characteristics,diagnosis,tre atment and prognosis.MethodsA retrospective study of p athological and clinical data of 4 cases of primary bladder carcinoid tumor was made.Three were male patients and 1 female with an average age of 58.Two cases w ere considered as benign carcinoid tumor whereas the other 2 carcinoid of high malignancy.All of them presented macroscopic or microscopic hematuria but with no carcinoid syndrome noted.ResultsOne case of maligna nt carcinoid tumor with deep muscle invasion underwent radical cystoprostatectom y and adjurvent chemotherapy,but the prognosis was poor (died 5 months after the operation).Transurethral resection were performed for 2 cases of benign carcino id tumor and 1 case of focal malignant carcinoid with good prognosis.ConclusionsThe primary carcinoid tumor of urinary bladder has no specific symptoms,and should be diagnosised on histopathologic studies.Surgical intervention is the mainstay to treat the disease but the prognosis is hard to b e predicted.
