The invention specifically discloses application of VGF as a diagnostic biomarker for prostatic cancer, and relates to the technical field of biological medicines. The secretory protein VGF is identified to be remarkably up-regulated in prostatic fluid of a prostatic cancer patient before puncture for the first time, high expression of the secretory protein VGF is proved to be independently related to shorter progression-free lifetime and total lifetime through a public database, and a brand-new liquid biopsy marker is provided for PCa non-invasive early screening and prognosis evaluation.

The utility model belongs to the technical field of body position pad, specifically a prostate massage multifunctional body position pad, it includes body position pad main part, one end of body position pad main part is swollen, the swollen end of body position pad is equipped with collection cavity, the other end fixedly connected with arm pad of body position pad main part, the one end fixedly connected with headrest of arm pad away from body position pad main part, the one end of swollen end away from arm pad is equipped with knee pad, beneficial effect: convenient patient one step to the position and comfortable to arrange knee chest lying position, the collection cavity at rear can place urine cup and leave prostate fluid in time.

The invention relates to the technical field of medical instruments, and discloses a balloon vibration pressing type prostatic fluid collecting device which comprises a handle and a vibration pressing assembly fixedly installed above the handle, the vibration pressing assembly comprises a rubber shell fixedly connected with the inner wall of the handle, and an external pipeline is fixedly connected to the outer wall of the rubber shell; an expandable balloon is arranged outside the external pipeline, the expandable balloon can be attached to the prostate contour in a self-adaptive mode after being filled with liquid, the expandable balloon can be tightly attached to the prostate contour in a self-adaptive mode after being filled with the liquid, a gap between the expandable balloon and the prostate can be eliminated in the massage process, and the massage effect is improved. The situation that part of the area cannot be effectively stimulated due to untight attachment is avoided, it is ensured that all the areas of the prostate can be effectively massaged and stimulated, and therefore the prostatic fluid extraction effect is remarkably improved.

The application discloses application of a silicone quaternary ammonium salt in preparation of a prostatitis typing diagnosis medical material, and the silicone quaternary ammonium salt can improve typing diagnosis of prostatitis, forms a biocompatible film of a molecular level or a nanotube in a urethra, prevents or destroys a bacterial biofilm, and the prostatic fluid flows out through the tube and is not polluted by bacteria and leukocytes, thereby improving a typing diagnosis rate, providing a basis for prostatitis treatment, and providing a new method for typing diagnosis of prostatitis.
