A memory power supply circuit includes a memory module, a micro control unit, a phase switch circuit, and a multi-phase pulse-width modulation controller. The compositions can comprise a plurality of different nucleosomal DNA fragments derived from either primary cells or cell lines. The multiple streak is initially the active streak. The sampling adsorber is utilized to absorb the body fluid secreted by the intima of an organ, and the filtering device is employed to prevent the mucosal tissue of the intima of the organ from entering the sampling adsorber and enable the body fluid secreted by the intima of the organ to enter the sampling adsorber, so as to be absorbed by the sampling adsorber.
