The US Preventive Services Task Force （USPSTF） analyzed the benefits and harms of prostate specific antigen （PSA）- based screening for prostate cancer （PCa）. The Grade ＇D＇ recommendation of the USPSTF was based mainly on the Prostate, Lung, Colorectal, and Ovarian （PLCO） study in the United States. That result showed only a small reduction in PCa mortality. However, the data from the International Agency for Research on Cancer （IARC） iUustrated the PCa mortality rate （MR） decreased marked. To avoid the over-diagnosis and over-treatment, the American Cancer Society has changed its strategy and updated its guidance. The USPSTF neglected the aggressive PCa accounted for more then 30% of all PCa. Highly aggressive PCa can be diagnosed by PSA screening combined with Gleason grade. We hope that the USPSTF changes the ＇D＇ recommendation for PSA screening.

This study proposed the design, fabrication, and assembly of membrane integrity detection instruments in membrane bioreactors (MBR) based on fluorescence spectroscopy. Based on the PARAFAC model, we found that the peak at 280/335 nm strengthened after membrane breakage. The peak at 340/430 nm reflected the sludge concentration in the MBR and reduced the influence of internal filtration effects on detection. Therefore, we determined that the dual-LED light source excitation detection system can detect tryptophan-like substances at 280 nm (T-peak) and humic acid at 340 nm (C-peak). T-peak was identified as the core index indicating membrane integrity. Moreover, the C-peak is the reference indicator factor for a sensitive response to changes in the sludge concentration. The portable fluorescence instrument exhibited high sensitivity and good feedback accuracy compared to particle counting and turbidity detection, where the log reduction value was greater than 3.5. This overcomes the disadvantage of false alarms in particle counters and is not affected by the position of the pump system. This portable instrument provides a flexible and highly sensitive method for the assessment of industrial membrane integrity.
