Objective To compare the result of T2/T3 transitional cell carcinoma (TCC) of the urinary bladder after segmental cystectomy, treated by postoperative radiation plus intravesical chemotherapy and postoperative intravesical chemotherapy alone.Methods From 1985 to Dec.1995 patients with T2/T3 TCC bladder cancer who had been treated by segmental cystectomy were eligible for this retrospective analysis. Fifty-eight patients received postoperative radiotherapy plus intravesical chemotherapy (RT+IVC) and 35 patients were given postoperative intravesical chemotherapy (IVC) with thio-TEPA or calmette-Gue'rin bacilli (BCG). For radiation,8 or 18 ?MV X-ray was given with total dose of 50-60 ?Gy. Vesicoclysis was performed on 50-60 mg thio-TEPA twice per week and 0.5 mg BCG per week.Results The 3-year local control rates of RT+IVC and IVC groups were 68.6% and 48.2% showing a difference statistically significant (? 2=4.08,P=0.044).The 3- and 5-year survival rates of RT+IVC and IVC groups were 70.7%,49.5% and 59.9%,35.7% ,showing no significant difference (? 2=1.77,P=0.184). Among the 5 year survivors of the RT+IVC patients, 78.6% had their bladder preserved. Though untoward radiation reactions were severer, they were tolerated well.Conclusions Combined radiation therapy plus intravesical chemotherapy is indicated for T2/T3 bladder cancer after segmental cystectomy. Multimodality therapy is more favored to improve both the local control and the possibility of preserving the bladder.

Objective:To investigate the effects of safflor yellow ( SY) on body fat, fatty liver and insulin resistance in diet-in-duced obese mice. Methods:Male C57BL/6 mice at the age of 4 weeks were fed with high fat diet ( HF) for 8 weeks to make the obese model. The mice were intraperitoneally injected SY (100 mg·kg-1 ·d-1 ) for 6 weeks. At the end of experiment, the introper-itoneal glucose tolerance test ( IPGTT) and insulin tolerance test ( ITT) were performed, and the body fat, blood lipid profile and the other metabolic parameters were detected. Meanwhile, the epididymis fat and liver tissue were withdrawn for HE staining, the adipo-cyte area was quantified and the morphology of liver was observed. Results:SY significantly reduced the body weight, body fat mass, adipocyte area, liver weight and blood lipid levels of the obese mice (P<0. 05), and fatty liver was obviously alleviated after the ad-ministration of SY. Meanwhile, IPITT and ITT tests showed that SY significantly improved the glucose intolerance and insulin resist-ance of the obese mice(P<0. 05). Conclusion:SY has significant weight-loss effects and it can alleviate fatty liver, and improve glu-cose intolerance and insulin resistance in diet-induced obese mice.

Objective To investigate the influence of different diluents(physiologic saline, dis-tilled water and human inactivated serum) on measurement of 15 items of biochemical parameters.Methods Fifteen items of biochemical parameters [alanine transaminase(ALT), aspartic transaminase (AST), alkaline phosphatase( ALP), gamma glutamyl transpeptidase ( GGT), creatine kinase ( CK),lactate dehydrogenase(LD), hydroxybutyrate dehydrogenase(HBDH), total bilirubin(TBIL), direct bilirubin(DBIL), total bile acid(TBA), ereatinine(Cr), uric acid(UA), eholesterol(CHO), glucose (GLU), and blood urea nitrogen(BUN)] were chosen. For each parameter, 45 serum samples with different eoncentrations of the parameter were collected. After diluted with different diluents(physio-logic saline, distilled water or human inactivated serum), the serum samples were detected by applying the fully automated biochemical analyzer. The mean value was calculated and statistical analysis was performed. Results There were some differences of detection results when the specimens were diluted with different diluents. ALT, AST, GGT, DBIL, and HBDH serum samples could be diluted by 10 times with physiologic saline, distilled water or human inactivated serums ALP and TBA serum sam-ples could only be diluted with inactivated serum, otherwise its result would be lower; GLU, TBIL samples could be diluted with distilled water and inactivated serums for BUN, CR, UA, CK, LDH,and CHO samples, physiologic saline or human inactivated serum might be optimal; if distilled water was chosen, the results of other parameters tented to decline except UA. It was BUN was improper to dilute the BUN samples with distilled water. In addition, there was no significant difference between the items diluted by 5 times and 10 times with physiologic saline. All the 15 items could be diluted with inactivated serum. Conclusion The inactivated serum should be the first choice of diluents to e-nure the accurate results of biochemical parameters. If the prepared inactivated serum is absent, we may choose other diluents according to the above-mentioned results.
