Objective To measure the concentration of electrolytes such as potassium,sodium,chloride,calcium in EPS and urine of patients with chronic prostatitis and to analyze the correlation of the electrolytes in different patient groups. Methods The concentrations of potassium,sodium,chloride and calcium in EPS and urine of 31 controls and 79 patients with prostatitis were measured and analyzed. Results There was no significant difference between the patients and normal controls in electrolytical concentration of potassium,sodium,calcium except chloride (P=0.001).The concentration of chloride in the patients was significantly higher than that in the normal controls.In the treatment effective group, potassium concentrations were decreased from 40.66?17.10 to 33.42?17.27 mmol/L after treatment.In the treatment ineffective group, potassium concentrations were (37.57?16.93)mmol/L before treatment and 50.66?18.77 mmol/L after treatment.Potassium concentrations were 36.02?12.36 and 48.90?16.93 mmol/L in the pain group and painless group,respectively.There were positive correlations between the concentrations of potassium and calcium of EPS,sodium and chloride of urine as well. Conclusions The concentrations of potassium in EPS are obviously different between the effective group and ineffective group or the pain group and painless group.There is a close relationship between the concentration of potassium and calcium of EPS,sodium and chloride of urine; and they are positively correlated.

Objective To establish animal model for hypertrophic scar and study the characters of its morphology and collagen metabolism. Methods A total of 64 round wounds (diameter of 6 mm each) with total skin loss were made on the ventral side of rabbit ear using a trephine. Morphology and collagen metabolism of scar wounds were studied at 14,21,35,70 and 98 days after operation, respectively. Results There were 76% elevated scars developed (45/59 wounds) on the ventral side of rabbit ear at 21 days and 46% elevated scars disappeared (11/24) at 98 days after operation. There were numerous fibroblast proliferation and whorl-arranged collagen fibers at 21 and 35 days. The number of fibroblast decreased, but irregular-arranged fibers still presented in the elevated scars at 70 and 98 days after operation. Hydroxyproline content in elevated scars at 21 days was higher than that in normal skin (P<0.05), and at 35 days was 3 times as that in normal skin and at 98 days was also markedly higher than that in normal skin (P<0.05). Conclusion Excessive deposition of collagen is a characteristic of hypertrophic scar in rabbits. The conversion of normal scarring to hypertrophic scarring in rabbits occurs at 14~21 days after operation. Both development and regression of hypertrophic scar in rabbit are quicker than that in human.

Objective To investigate the effect of reptroperitoneal laparoscopic operation on the parameters of platelet, D-dimer and thrombomodulin(TM). Methods Forty cases were divided into two groups according to the operative way, retroperitoneal laparoscopic operation (n= 20) and open operation (n=20). Blood samples were taken preoperatively and at the end of the surgery. The following parameters were measured and compared within each group and between groups: platelet count (PLT), mean platelet volume (MPV), platelet distributionwidth(PDW), D-dimer, TM. ResultsThere were no significant differences for the PLT, PDW, MPV, TM and D-dimer between before and after operation in each group. There was no difference between 2 groups either for all these indicators.No patients from either group suffered thrombosis or abnormal bleeding as a pastoperative complication. Conclusion Compared with the conventional operation, retroperitoneal laparoscopic operation dioesd not induce more change on parameters of platelet, D-dimer and TM.

Objective To analyze the diagnosis and treatment for complications of renal caliceal diverticulum with calculi or infection. Methods A retrospective investigation was performed on 29 cases with renal caliceal diverticulum. The 29 cases included 11 males and 18 females aged 18 to 61 years. Among the study group, 3 cases were simple renal caliceal diverticulum, 12 cases were diagnosed as diverticular calculi and 14 cases presented recurrent urinary tract infections including 3 cases with urinary fistula after unroofing and decompression as renal simple cyst from another hospital. Ten cases underwent an open operation that unroofed and decompressed the cyst, and sutured the diverticular neck. Eight cases underwent laparoscopic operation similar to the open operation, including lithotomy in caliceal diverticulum in 2 cases. Eleven cases diagnosed with caliceal diverticular calculi were taken one-stage percutaneous nephrolithotomy including dilating the diverticular neck, remaining the nephrostomy catheter and Double-J ureteral stents, and 1 case was transferred to open operation.Results The open and laparoscopic operations were performed successfully. One case was cured by Double-J ureteral stenting after postoperative urinary leakage. One case was transferred to open operation for the failure of percutaneous puncturation. X-ray examination revealed that there were no remaining stones after the operation. All the patients were followed up for 6 to 24 months without calculi and infection recurrence. Conclusions Stones and infection are common that complications of renal caliceal diverticulum. Percutaneous nephrolithotomy, laparoscopy and other operations were effective and feasible treatment options for cases with complications of renal caliceal diverticulum. Exact diagnosis was very important for treatment of renal caliceal diverticulum before operation.
