Objective: To analyze chromosome aberrations in bladder transitional cell carcinoma with exfoliated cells, and to evaluate the clinical value of fluorescence in situ hybridization (FISH) in bladder cancer. Methods: FISH was performed using centromeric probes of 3, 7, 17 and locus probe of p16 to examine chromosome aberrations of exfoliated cells of 56 bladder cancer patients and 20 healthy controls to analyze the correlation of chromosome aberration with the pathological features of bladder cancer. The urine cytology of the 56 bladder cancer patients was performed. Results: The rates of aneuploidy of chromosomes 3, 7, and 17 were 58.9%, 39.3%, 58.9% and 75.0% for aberration of p16 in exfoliated cells from the 56 bladder cancer patients. All of the aberrations had no correlation with tumor stage (P>0.05). The aberrations of chromosomes 3, 7, and 17 were significantly correlated with pathological grade (P<0.05). The sensitivity of the 4 chromosome probes for detecting bladder cancer was 80.4%. The detection rate of FISH was obviously higher than that of udne cytology. Conclusion: Chromosome aberration is correlated with the growth of bladder cancer. The detection of FISH has significance for early di-agnosis, prognosis evaluation, and recurrence monitoring of bladder cancer.

Objective:To observe the inhibition of Chuanhong Baliu Paste on S180 tumor and investigate its apoptotic induction. Methods:60 mice were divided into 5 groups randomly after inoculating S180 tumor. S180-bearing mice were smeared with different dosages of Chuanhong Baliu Paste respectively on skin of right armpit. Model group was administrated with normal sodium and positive group was injected intraperitoneally with Cyclophosphamide (25mg/kg) respectively. The growth inhibition was evaluated; apoptotic cells were detected by DNA agarose gelelectrophoresis and flow cytometry. The expression of Caspase-3 was determined by reverse transcription polymerase chain reaction method.
