Objective To evaluate the quantitative determination of urine nuclear matrix protein 22 (NMP-22) and bladder tumor antigen (BTA) in the screening of bladder tumor recurrence. Methods 90 patients who had undergone TURBT were recruited in this study.Standard ELISA test was used to determine the quantity of NMP-22 in urine and urine BTA stat test was also performed.the findings were analyed with reference to the cystoscopic and pathological results. Results In comparison with the results of cystoscopy,urine NMP-22 test might denote 77% (32/43) recurrence of bladder cancer and this positive rate would increase to 93% (40/43) with the combined use of urine NMP-22 and BTA test. Conclusions Examination of NMP-22 in urine is a rapid and effective means of detecting the recurrence of bladder cancer.With the combined use of BTA test,urine NMP-22 determination might be a useful non-invasive method in screening the recurrence of bladder cancer,and the conventional invasive cystoscopy might be avoided.

0) and the correlation coefficient were low.The absence of intravesical occurrence of the cancer in solitary primary tumor cases was significantly less than that in the multiple ones ( P =0).The intravesical occurrence rate of the cancer elevated with the pathological stage of the primary cancer ( P =0.0039).92.5% of cases with initial concurrent involvement of the bladder have had the occurrence of bladder cancer within 2 years after surgical treatment. Conclusions The number and the stage of the primary tumor,with concurrent bladder involvement or not and the internal between the occurrence of the bladder cancer and the upper urinary tract cancer are the significant factors for prognosis,the coefficient correlation between the 4 factors being low.

Objective To verify the presence of tumor necrosis factor receptor (TNF R 2) in spermatozoa of fertile men,and to provide experimental evidence for the direct action of TNF on spermatoza. Methods Using Western blotting the expressions of TNF R 2 in spermatozoa of 15 fertile men were assessed. Results TNF R 2 was expressed in spermatozoa of all the 15 fertile men. Conclusions The spermatozoa of fertile men have TNF R 2,which may transmit the cytokines signal into cytoplasm and modulate the spermatozoa function.

Objective To evaluate the inhibitory effect of endostatin on bladder tumor and to investigate the possible mechanism of the inhibition. Methods (1)By means of MTT method,the effects of endostatin on ECV304 and EJ cells proliferation were studied.(2)Ten nude mice were subcutaneously implanted with EJ bladder tumor cells (1?10 7/ml). After the tumor volume exceeded 100～200 mm 3,the mice were randomized into two groups.One group received recombinant human endostatin (2 mg?kg -1 ?d -1 ) whereas the other group received PBS as control.All the treatment lasted 21 days.(3) After that,the mice were sacrificed and then MMPs and TIMPs mRNA expression were measured in implanted tumor by RT PCR and Western blot method. Results (1)Endostatin inhibits ECV304 proliferation stimulated with bFGF (5 ng/ml).In addition,we report for the first time that endostatin also inhibits EJ cells proliferation.(2)The mean tumor weight of endostatin treated group (0.70?0.16 g) was significantly lower than that of control group (1.14?0.21)g, P
