A method and device for detecting acne quantitative information, the method comprising: based on optical imaging technology, acquiring coordinate information of each area acne and corresponding physical characteristic information, the physical characteristic information at least including fluorescence intensity signal and light intensity signal; acquiring physiological characteristic information of each area acne according to the physical characteristic information of the area acne, the physiological characteristic information including bacterial content and blood oxygen saturation; wherein the bacterial content of acne is acquired based on the fluorescence intensity signal, and the blood oxygen saturation of acne is acquired based on the light intensity signal; fitting calculation is carried out based on the physiological characteristic information of each area acne, and a quantitative detection result for representing the lesion degree of acne is obtained. In this application, through the fitting operation of the physical characteristic information and the physiological characteristic information, the fitting result is calculated, the fitting result is used for quantitative detection of acne, so as to classify and grade, so as to be able to objectively detect acne and improve the detection accuracy of acne.

The application discloses a DNA methylation biomarker composition for bladder cancer detection and application thereof, and the DNA methylation biomarker composition comprises any two or any two or more combinations of markers OTX2_28, PTPRN2_16, cg05091238_46, cg11536474_41, cg19763461_39 and cg25092838_2nd_55. A kit for detecting bladder cancer can be prepared according to the six markers, the kit can be used for simultaneously detecting DNA methylation levels of the six markers, the kit overcomes the defect of low single DNA methylation signal, the detection result is more accurate, and a non-invasive detection mode can also avoid complications caused by cystoscopy.

The application belongs to the technical field of edible fungus physiological characteristic detection, and discloses a determination method and application of reed coprinus micaceus mycelium aging, which quantitatively evaluates the aging degree of mycelium by detecting the changes of carboxymethyl cellulase (CMC) enzyme activity and TTC (triphenyltetrazolium chloride) reductase activity in the reed coprinus micaceus mycelium. The application quantitatively determines the aging degree of the reed coprinus micaceus mycelium by establishing double-enzyme activity indexes. The CMC enzyme activity directly reflects the nutritional acquisition ability of the reed coprinus micaceus mycelium, and the TTC enzyme activity indicates the overall vitality of cells, so that the combination of the two can comprehensively capture the aging characteristics and avoid the limitations of a single index.
