Abstract: Provided is a finger tendon sheath brace capable of adjusting fixing pressure, including a brace fixing plate, a compression screw, a compression plate, an adjustable pressure push rod and a spring. The brace fixing plate is configured as a fixing structure for accommodating a finger to extend in the finger tendon sheath brace, and is provided with a threaded opening in a center of the brace fixing plate in a vertical direction perpendicular to the finger. The compression screw is embedded in the threaded opening of the brace fixing plate through threads to make an end of the compression screw slightly higher than the brace fixing plate and a head end of the compression screw pass through the brace fixing plate and enter a cavity for accommodating the finger. The compression plate is connected with a head end of an adjustable pressure push rod inner sleeve.

Abstract: A nerve conduit loaded with adipose-derived stem cells and a preparation method thereof are provided. The preparation method includes: S1, adding polycaprolactone and polyvinylpyrrolidone into a binary organic solvent, performing ultrasonic treatment, and then adding reduced graphene oxide nanoparticles to obtain a spinning solution; S2, electrospinning with the spinning solution and then washing for several times to obtain a semi-finished conduit product; and S3, injecting a cell mixture into the semi-finished conduit product to obtain the nerve conduit. A fiber surface of the nerve conduit has groove structures, and thus a specific surface area and cell adhesion sites are increased, and adhesion and proliferation of cells are facilitated.

Abstract: A coating composition including (a) a first polyester material having a number-average molecular weight (Mn) of 500 to 5,500 Daltons, and (b) a second polyester material having a number-average molecular weight (Mn) of 6,000 to 100,00 Daltons. The first polyester material may have a glass transition temperature (Tg) of from 40° C. to 120° C. The coating composition is useful for, among other things, coating food and/or beverage containers, such as an undercoat layer of a two layer coating system that includes an undercoat layer and an overcoat layer.
