Abstract: The present disclosure provides a method for preparing a composition including mesenchymal stem cells, extracellular vesicles produced by the mesenchymal stem cells, and growth factors, the composition prepared by the method, and use of the composition for treating arthritis. The composition of the present disclosure achieves the effect of treating arthritis through various efficacy experiments.

Abstract: An integrated circuit (IC) structure includes a semiconductor substrate, a first gate line, a second gate line, and a first auxiliary gate portion. The semiconductor substrate comprises a semiconductor fin. The semiconductor fin extends substantially along a first direction. The first gate line and the second gate line extend substantially along a second direction different form the first direction from a top view. The first auxiliary gate portion connects the first gate line to the second gate line from the top view.

Abstract: A prone position ventilation health bed includes a front bedstead pivotally connected with a rear bedstead. The frame includes two side bars and a front crossbar connecting the two side bars. Two parallel fixed bars are transversely mounted between the two side bars. A head and face support rack is transversely arranged and movable between the front crossbar and one of the two fixed bars. A left chest and abdomen support rack and a right chest and abdomen support rack are longitudinally arranged between the two fixed bars. The left chest and abdomen support rack and the right chest and abdomen support rack are parallel with each other and are movable between the two fixed bars. Thus, the user's head, face, chest, and abdomen are exposed outward without being pressed when the user is situated at the prone position.

Abstract: A foldable bed includes a base, a first frame and a second frame. The first frame is provided with two chest and abdomen support rods. The first frame is connected with two retractable bars which are connected with a head support. The second frame is provided with a plurality of support bars. Thus, when the user is disposed at a prone positioning state, the two chest and abdomen support rods are adjusted to fit the user's body, such that the user's chest and abdomen are exposed and will not be compressed, while the head support is adjusted to fit the user's face, such that the user's eyes, nose, mouth and ears are exposed and will not be compressed, to prevent the user's respiratory tract from being clogged.

Abstract: A multipurpose prevents epidemics band contains a body, at least one elastic rope, and an adjusting member. The body includes a first outer layer, a second outer layer, and a movable replacing layer. The first outer layer is attached on the second outer layer, and an accommodating pocket is defined between the first outer layer and the second outer layer and has at least one opening so as to accommodate the movable replacing layer. The first outer layer has a filtering nonwoven fabric soaked with herbal liquid. The at least one elastic rope is inserted into two opposite sides of the body, and the adjusting member is fixed on each of the at least one elastic rope. Thereby, the body is hanged on user's head or other portions, and the adjusting member is arranged to adjust an expansion and retraction of the at least one elastic rope.

Abstract: A Venturi tube device is provided with a Venturi tube; a hollow cylindrical fitting; a shroud; and a hollow, cylindrical flow guide member disposed in the Venturi tube. In a showing operation, air can flow through one communicating hole of the shroud, a space defined by two adjacent ridges on the fitting, a conic hole between the two adjacent ridges, and a transverse hole of the Venturi tube in addition to water flowing through the flow guide member and the Venturi tube.
