The invention discloses an application of adipose tissue-derived stromal cells in treating premature ovarian failure, and belongs to the technical field of a biological medicine. Adipose tissue-derived stromal cells and its excreted cell factors, and other components at a certain ratio are applied to form adipose tissue-derived stromal cells; then the adipose tissue-derived stromal cells are prepared to be injection fluid and a drug patch; the injection fluid is injected to the zone where a focus locates through a local target injection method, and then the patch is pasted to a patient's navel; through an electromagnetic impulse generator, a drug is intermittently stimulated, and the secretion of follicle-stimulating hormone is promoted, ovary endometrium can be effectively repaired, the functional ovulation is promoted, and premature ovarian failure is effectively treated. In short, the application has the advantages of being safe and effective, higher in controllability and strong inpracticability.

The present invention discloses a novel chemical drug patch ketoprofen paster and a preparation method thereof. The novel chemical drug patch ketoprofen paster comprises a styrene-isoprene-styrene triblock copolymer, a styrene-isoprene diblock copolymer, a tackifier, a softener and an antioxygen; the patch has the characteristics that the stimulation to skins is very slight, an adhesive is free from the stimulation to the skins, the drug stabilization in long-term storage is good, the pasting with the skins is good, the repeatable pasting is realized, pasting is kept when contacted with water, particularly the pasting with knees, elbows and other parts; the adhesive in the patch comprises components in percentage by weight: 10%-55% of the styrene-isoprene-styrene triblock copolymer and the styrene-isoprene diblock copolymer totally, less than 22% of polyisobutene with high molecular weight, less than 30% of polyisobutene with middle molecular weight, less than 25% of polyisobutene with low molecular weight, 10%-60% of the tackifier, and 12%-55% of the softener; the antioxygen accounts for 0.01%-2.5% of the sum amount of framework materials.

The invention relates to a biphasic transdermal drug delivery system and a preparation method thereof, which is obtained by using the drug-loaded ethosome / natural material nanofiber membrane as a receiver to receive electrosprayed drug-loaded ethosome composite microspheres. The invention has good skin compatibility, air permeability and water permeability, and will be softer when wet, and more closely adhered to the skin, and is an ideal material for a transdermal drug delivery patch.

A beauty / medication patch including a substrate, an outer layer, and a medication lotion; the outer layer being made of a degradable material being disposed on the substrate; one or a plurality of micro-probe array being disposed on a surface of the outer layer; the medication lotion being coated between the substrate and the outer layer, and / or admixed in the substrate; the patch being attached to a human skin, the micro-probe array piercing through a stratum corneum layer of the human skin and naturally being degraded by human skin or absorbed and metabolized by a human body; and the medication lotion penetrating into the skin and being absorbed by the human skin.

The invention relates to a drug patch and equipment with heating and cooling functions, and belongs to the technical fields of make-up and skin care products as well as medical equipment. The drug patch and equipment are utilized for nursing or treatment of the chest, abdomen, face, elbow joints, knee joints and several other parts of a human body. The equipment comprises the drug patch, a heating and cooling device, a DC power supply device, a feeding device and an intelligent control device, wherein the drug patch comprises two or more layers of closed film bag-shaped patches; closed channels are formed in the drug patch; a quick connector B is arranged at the lower end of the drug patch; tiny capillary porosities are formed in both the closed channels and the closed film bag-shaped patches; a drug can be separated out through the tiny capillary porosities, and permeate into a corresponding part of a user; a plurality of bulges are arranged on the drug patch and have a massage function, so that the drug using effect of the drug patch is improved. The drug path and equipment are rapid in cooling and heating, free of noise and low in energy consumption; through adoption of the drug patch, skin pores can be expanded or shrunk, so that the drug can be sufficiently absorbed, and the nursing or treating function of the drug can be more obvious.
