The invention discloses application of porous frame materials in masks. To solve the problems that a traditional mask matrix is high in irritation and poor in cleaning capacity, an added homogeneous preservative easily causes skin allergy and inflammation, and active matter can not be fully utilized, the high adsorbability and antibacterial property of the porous frame materials and the property of slowly releasing active ingredients are creatively utilized to solve the problems in the existing mask technology. Meanwhile, through many experiments and long-term exploration, screening criteria of the porous frame materials for different kinds of masks are established, and the interaction mechanism of the porous frame materials and guest molecules is studied according to the material structures.

The present invention provides methods for predicting the in vivo skin sensitizing activity of chemical compounds using a combination of mammalian cell models with multiple endpoint analysis, time and concentration response curves. The methods allow the determination of a predicted in vivo sensitization value of a compound—for example, a EC3 LLNA value, a GPMT value or a IVTI value—without the use of animals, with a high degree of accuracy. The methods involve detecting expression levels of genes implicated in skin sensitization, combining expression level data with concentration response data, conducting a computational analysis, and comparing test compound data to a database of known skin sensitizers.

The invention provides an externally used medicament for expelling rheumatism, promoting blood circulation and relieving a pain and a preparation method thereof. The medicament is prepared from a pain-relieving liquid extract for affections by dampness, methyl salicylate, menthol, borneol, camphor, liguidamber resinoid and belladonna liquid extract. The externally used medicament for expelling the rheumatism, promoting the blood circulation and relieving the pain links the cause and the pathogenesis of a disease closely, has medicaments in compatibility with each other reasonably, expels the rheumatism, promotes the blood circulation and relieves the pain. Serving as an externally used cataplasm which is applied through skin, a stimulus to a gastrointestinal tract caused by oral preparations is avoided, and toxic and side effects on a whole body are lightened necessarily by a relatively slow absorption process through the skin without the reactions of skin sensibility and skin stimulus. Therefore, the externally used medicament improves the medicinal safety to a certain extent and provides a new choice for clinical medicinal safety after the medicament is delivered through the skin.

The invention provides a dog-skin plaster and a preparation technique thereof. The dog-skin plaster is made from a substrate and raw herbal materials of black-plaster dog-skin plasters. The mass ratio of the raw herbal materials is the same as the mass ratio in the prescription of the black-plaster dog-skin plaster. A processed radix aconiti replaces an unprocessed radix aconiti, and a processed kusnezoff monkshood root replaces an unprocessed kusnezoff monkshood root, wherein no lead is contained. The preparation uses an ethanol extracting technology and a volatile-oil extracting technique to replace the extracting technology of frying vegetable oil in the original preparation, which can completely extract drug ingredients, without such disadvantages as drug ingredients being easily destroyed by high temperature and air pollution which are generated by the extracting technique of frying vegetable in the original preparation; the new substrate replaces the original black-plaster substrate, which has the advantages of larger drug quantity, easy putting up and off, good compatibility, release property and skin penetration property, without toxic lead content. The unprocessed radix aconiti and the unprocessed kusnezoff monkshood root in the original prescription are replaced respectively by the processed radix aconiti and the processed kusnezoff monkshood root, thus ensuring the effectiveness and safety of the preparation and eliminating the skin sensitization caused by the original dog-skin plaster.
