The present invention relates to an osmotic pump controlled-release tablet of an insoluble drug and a preparation method therefor. The osmotic pump controlled-release tablet comprises a tablet core, a semi-permeable membrane coating and a drug-release hole, wherein the tablet core comprises a solid dispersion of the insoluble drug and a penetration enhancer, the solid dispersion of the insoluble drug comprises the insoluble drug and a carrier, the insoluble drug is selected from nicardipine, nifedipine and felodipine and pharmaceutically acceptable salts thereof, and the carrier is selected from organic acids. Compared with the prior art, the drug solubility of the osmotic pump controlled-release tablet of the insoluble drug of the present invention is greatly improved, a large amount of penetration enhancers or other excipients do not need to be used in the tablet core, the drug-loading capacity is improved, and the tablet core is not too large; the degree of release in vivo is greatly improved; and the preparation process is simple, has low requirements for equipment and a low cost, and facilitates industrialized production.

Provided is a method of manufacturing a skin attachable thin film coated with a functional mixture, the method including: preparing a microstructured thin film including a base thin film and at least one microstructure protruding from the base thin film; and coating a functional mixture on the microstructure excluding a region of the base film of the microstructured thin film, wherein in the coating the mixture, the functional mixture is irregularly coated on the at least one microstructure.

Provided is a Low-E glass plate protective sheet having excellent long-term reliability. A Low-E glass plate protective sheet is provided. The protective sheet has a PSA layer. The PSA layer has a chloride ion amount of 105 µg or less per gram of PSA, determined by hot water extraction.

The present application relates to a multi-layer film comprising a nutrient material for cell culture, a method for preparing same, and the use of same. The multi-layer film of the present application can be utilized for cell culture for preparing cultured meat.

A rotating pad holder (10) adapted to hold a textile pad (20) and adapted to be engaged with a driving unit of a wet vacuum cleaner nozzle having a water supply unit (17), wherein the pad holder (10) comprises a first set (11) of openings (15) arranged in a circle, wherein the center of the circle coincides with a rotation axis of the pad holder (10) and an arrangement of ribs (13) for water distribution, wherein a second set (12) of openings (15) is arranged on a circle which radius (R1) is greater than the radius (R2) of the circle on which the first set (11) of openings (15) is located, wherein outer walls (16) of openings (15) of the second set (12) are inclined towards the center of the pad holder (10). The present invention enables a rotating pad holder for vacuum cleaner of construction which facilitates the evenness of water distribution and faster penetration of the water into the pad thanks to which the device is ready for operation very fast. The cleaning results of the device are improved with no production costs increase.
