This invention provides a traditional Chinese medicine compound for treating chronic pharyngitis, belonging to the field of biomedical technology. The invention comprises a self-formulated traditional Chinese medicine compound consisting of *Pearl Umbrella*, *Trichosanthes kirilowii*, *Sapindus mukorossi*, *Lycoperdon perlatum*, *Panax japonicus*, *Gnaphalium affine*, *Aster tataricus*, and prepared licorice root for the treatment of chronic pharyngitis. Addressing the complex pathogenesis of chronic pharyngitis, characterized by a mixture of deficiency and excess, phlegm and blood stasis, and yin deficiency, the ingredients in the compound are rationally combined and work synergistically to achieve the effects of promoting blood circulation without depleting yin, clearing heat without harming yang, resolving phlegm without hindering the spleen, nourishing yin without being cloying, combining tonification and purgation, using both warming and cooling methods, and treating both the root cause and the symptoms. This compound is suitable for the treatment and management of chronic pharyngitis.

The invention belongs to the technical field of food processing, and particularly relates to a panax japonicus and dendrobium protocorm co-extract as well as a preparation method and application thereof. The preparation method of the co-extract comprises the following steps: (1) extraction: mixing panax japonicus and dendrobium protocorm, adding a natural deep eutectic solvent, controlling the solid-to-liquid ratio to be 1: (30-50) g / mL, and extracting under an ultrasonic condition to obtain a crude extract; (2) anti-solvent precipitation and purification: dropwise adding the crude extract obtained in the step (1) into excessive ethanol, standing for precipitation, and carrying out centrifugal separation to obtain a precipitate; and (3) drying treatment: drying the precipitate obtained in the step (2) at 40 DEG C until the weight is constant, so as to obtain the panax japonicus and dendrobium protocorm co-extract. The co-extract can remarkably promote proliferation and acid production of various probiotics, effectively regulate intestinal flora balance, show excellent prebiotic activity and have the potential of being developed into functional medicines or health-care foods.

This utility model discloses a storage and preservation device for bamboo-joint ginseng, including a sealed box. A light-shielding layer is fixedly installed on the inner wall of the sealed box, and the box is divided into multiple inner cavities by at least one dividing layer. A drawer unit is slidably installed in each inner cavity, and the bottom of the drawer unit is provided with a wavy, hollowed-out elastic silicone mesh tray. The light-shielding layer is connected to the lower part of the dividing layer via a disassembly and assembly mechanism. This utility model offers upgraded physical protection: the hollowed-out structure of the wavy, elastic silicone mesh tray disperses the stress on the bamboo-joint ginseng nodes, resulting in a reduced fracture rate when the ginseng is subjected to a 500g load. The light-shielding layer is efficiently disassembled and assembled: the Y-shaped insertion groove and the inclined guide design of the limiting block shorten the replacement time of the light-shielding layer, and the elastic component automatically locks to prevent loosening.

The application belongs to the technical field of traditional Chinese medicine, and particularly relates to a preparation method and application of a Gastrodia elata Yin-boosting oral preparation. The oral preparation comprises the following raw materials in parts by weight: Gastrodia elata 20-25 parts, Rehmannia glutinosa 15-20 parts, Cornus officinalis 14-17 parts, Fructus Lycii 17-21 parts, Rubus corchorifolius 15-20 parts, Anoectochilus roxburghii 10-15 parts, Ophiopogon japonicus 10-20 parts, Polygonatum odoratum 10-14 parts, Panax ginseng 5-10 parts, Atractylodes macrocephala 7-12 parts, Poria cocos 5-10 parts, Ziziphus jujuba var. spinosa 10-15 parts, Schisandra chinensis 5-10 parts, Angelica dahurica 5-8 parts, Angelica sinensis 1-5 parts, and Glycyrrhiza uralensis 3-8 parts. Animal experiments prove that the oral preparation can prolong the exhaustive swimming time of mice, reduce the content of blood lactic acid and serum urea of mice after swimming, increase the storage of liver glycogen, and has a significant anti-fatigue effect.

This invention discloses the application of *Gynostemma pentaphyllum* polysaccharide in the preparation of drugs against porcine reproductive and respiratory syndrome virus (PRRSV). This invention explores the regulatory effect of *Gynostemma pentaphyllum* polysaccharide on PRRSV replication, and for the first time discovers that *Gynostemma pentaphyllum* polysaccharide can effectively inhibit PRRSV replication in Marc-145 cells. Based on this, this invention proposes a new application of *Gynostemma pentaphyllum* polysaccharide in the preparation of drugs against PRRSV, preferably with a concentration of 12.5 μg / mL to 100 μg / mL. This invention enriches the research on the antiviral activity of *Gynostemma pentaphyllum* polysaccharide and also provides a new technical means for the research and clinical application of anti-PRRSV drugs.
