Methods: A total of 135 elderly male and 50 healthy volunteers enrolled in this study were classified into three groups: (i) 93 patients with bladder cancer; (ii) 42 patients with urinary benign conditions; and (iii) 50 healthy volunteers. BTA TRAK and NMP 22 kits were used to detect bladder cancer. Voided urine cytology was used to compare the sensitivity and specificity of the screening tests. Results: The sensitivity and specificity of cytology, BTA TRAK and NMP 22 were 24% and 97%, 51% and 73%, 78% and 73%, respectively. The level of NMP 22 increased with tumor grading. The BTA TRAK kit has the lowest sensitivity among the screening tests. The NMP 22 with the best sensitivity can be an adjunct to cytology for evaluating bladder cancer. Conclusion: The NMP 22 test has a better correlation with the grading of the bladder cancer than BTA TRAK. As cytology units are typically not available in hospitals or in outpatient clinics, NMP 22 might be a promising tool for screening bladder cancer.展开更多

The unique structure and excellent enzyme mimetic activity of porous Pd nanoparticles favor to oxidize o-phenylenediamine (OPD) into 2,3-phenazinediamine (oxOPD) by H2O2, producing colorimetric and fluorescence dual-readout signal for the detection of NMP 22. The developed immunoassay method will offer great potential in clinical research and diagnostic applications.展开更多
