The method includes administering to a subject in need thereof a therapeutically effective amount of mesenchymal stem cells or secretome thereof, wherein the mesenchymal stem cells or secretome are derived from human amniotic fluid.

Abstract: A centrifugal fan is disclosed and includes a lower case, an impeller and an upper case. The lower case includes a bottom plate and a sidewall. The impeller is disposed on the bottom plate. The upper case is assembled with the sidewall to form an outlet. The upper case is formed by stamping and includes a first plane, an inlet and a grille. When the impeller is rotated, an airflow flowing from the inlet to the outlet is formed. The grille is protruded outwardly from the first plane, and includes a connecting frame and plural ribs. A spacing height is formed between the connecting frame and the inlet. Each rib has a first end connected to the connecting frame and a second end connected to the first plane. A pair of notches are disposed adjacent to two opposite lateral edges of the second end of the corresponding rib, respectively.

Abstract: An impeller includes a fan frame, a hub, a plurality of axial blades and a plurality of wind guiding blades. The fan frame has a wind inlet, a wind outlet and an inner ring-shaped oblique surface, wherein the wind inlet is opposite to the wind outlet, and the inner ring-shaped oblique surface is formed at an inner side wall of the fan frame and adjacent to the wind inlet. The hub is disposed in the fan frame. The axial blades are connected to the inner side wall of the fan frame and the hub. The wind guiding blades protrude from the inner ring-shaped oblique surface.

Abstract: A pico projection fixing module includes a bracket main body, plural color light sources, and plural collimator lenses. The bracket main body includes plural assembling seats. The plural assembling seats are arranged side by side. Each of the plural assembling seats includes a first assembling part and a second assembling part beside the corresponding first assembling part. The plural color light sources are installed on the first assembling parts of the plural assembling seats, respectively.

Abstract: The present invention discloses an aberration correcting method for use between an optical disc drive and an optical disc. The optical disc drive includes an optical pickup head having an aberration-correcting unit and a control chipset. The method includes steps of: operating the optical pickup head in a focusing-locked and tracking-unlocked state; generating a read-back signal by projecting a laser beam to the optical disc; converting the read-back signal into a radio frequency signal and a tracking error signal by the control chipset; detecting corresponding amplitudes of the radio frequency signal or the tracking error signal at different compensation values by the control chipset; determining a target compensation value by selecting the compensation value corresponding to the maximum amplitude of the tracking error signal or the radio frequency signal; and controlling the aberration-correcting unit according to the target compensation value.
