Objective: To investigate the action of low level soybean isoflavones (genistin, genistein and daidzein) on the oxidative modification of lipoproteins in serum. Methods: After a system of lipoprotein oxidation mediated by Cu 2+ was established in a dilute serum, the effects of soybean isoflavones on the course and the end of lipoprotein oxidation could be reflected by monitoring the production of conjugated dienes and thiobarbituric acid-reactive substances (TBARS) respectively when isoflavones were added. Results: After 0.5-10 ?mol/L genistein, daidzein, genistin or ?-tocopherol was added into the lipoprotein system respectively before the oxidation initiated by Cu 2+ , the production of conjugated dienes or TBARS in the system was significantly reduced with a dose-dependent relationship. When the lipoprotein oxidation was initiated by Cu 2+ at 37 ℃ for 1 h or 1.5 h, soybean isoflavones also revealed strong inhibition on the oxidation in a weakening way. In comparison with soy isoflavones, ?-tocopherol had smaller inhibition on the production of conjugated dienes, but had promotion on the increase of TBARS. Conclusion: Lipoprotein oxidative modification in serum was weakened by low level soybean isoflavones, and its action after the oxidation initiated was more effective than that of ?-tocopherol.

Objective To improve the diagnosis and treatment of ureteral cancer. Methods A retrospective analysis of 24 cases of primary ureteral cancer treated from January 1990 to March 2005 was performed.The diagnostic value of ultrasound,IVU,CT,MRU and the patients' outcomes were reviewed. There were 19 males and 5 females aged 38-72 years(mean,59 years).The tumors were on the left side in 16 cases and on the right in 8.Of the 24 cases,17(71%)had gross hematuria and 7(29%)had micro- scopic hematuria.Urine cytology was performed in 16 cases with a positive rate of 6.3%.B-ultrasonic exami- nation showed hydronephrosis in 19 cases(79%)and low-echo space-occupying disease of middle-inferior ureter in 3(12%).IVU demonstrated hydronephrosis in 20 cases(83%)and filling defect of the diseased ureter in 3(12%).Retrograde pyelography showed filling defect of the diseased ureter in 16(76%)of 21 cases(5 cases had failure of intubation).CT scan was performed in 20 cases,indicating thickening of the ureteral wall and infiltration of the cancer in 14(70%).In 3 cases who had undergone spiral CT thin layer scan and 1 of 3 cases who had undergone MRU,the definite diagnosis was made.Results All the 24 pa- tients underwent surgical treatment.Among them,nephroureterectomy and bladder cuff or partial resection were performed in 18 cases,and nephrectomy and partial ureterectomy in 6 cases.Postoperative pathology showed transitional cell carcinoma in 23 cases,and adenoma in 1.Of the 14 cases during 1990-1999 peri- od,1,5,3,2,2 and 1 cases had survival time of 1,2,3,4,5 and 6 years,respectively.Of the 10 cases during 2000-2005 period,3 were lost to follow-up;2 survived for 3 years and 2,for 1 year;the other 3 who have survived near 5 years have been followed till now.Conclusions IVU and retrograde urography are the most common diagnostic measures for primary ureteral cancer.They can be used in combination with other imaging study to reduce missed diagnosis rate.The 5-year survival rate was lower because of late pathologic stage of the tumors in the patients of this series.
