The compound extract is extracted from a composition at least comprising the following raw material medicines in parts by weight: 0.9-10 parts of tricholoma matsutake, 0.9-10 parts of mulberry and 0.5-10 parts of rhizoma polygonati. The raw material medicine composition further comprises the following raw material medicines in parts by weight: 0.7-10 parts of longan, 0.5-10 parts of pericarpium citri reticulatae, 0.5-10 parts of scorched hawthorn fruit, 0.5-10 parts of fructus amomi, 1.1-10 parts of cordyceps sinensis rice flour and 2.5-15 parts of rice peptide. The selected raw material medicines are all medicinal and edible components, do not cause adverse effects on liver and kidney functions and gastrointestinal tracts of eaters, and are high in safety and high in patient acceptance degree. Effect verification results show that the mulberry compound extract has an improvement effect on the side effect of bone marrow suppression of tumor patients, especially in the early stage, no related adverse reaction is found, and a safe and effective treatment choice is provided for bone marrow suppression.

The present invention provides a positive electrode for a lithium secondary battery and a lithium secondary battery comprising the same. In the positive electrode, a positive electrode additive represented by Chemical Formula 1 is contained in a positive electrode mixture layer, and control is performed on a specific X-ray diffraction (XRD) and / or extended X-ray absorption fine structure (EXAFS) peak such that cobalt remaining in the positive electrode mixture layer after initial charging to SOC 100% has a specific oxidation number, thereby improving a side reaction caused by an irreversible additive, i.e., the positive electrode additive, and reducing the amount of gas such as oxygen generated during charging / discharging. Accordingly, the lithium secondary battery has an excellent effect of improving battery safety and electrical performance.

The invention provides a lithium ion battery electrolyte and a lithium ion battery containing the same. The lithium ion battery electrolyte comprises an electrolyte, a non-aqueous organic solvent and an additive, the additive comprises a film-forming additive and at least one compound A, and the compound A has a structure as shown in any one of formulas I-V. By adding the compound A, a layer of protective film can be formed on the surface of the negative electrode, and meanwhile, water and HF acid in the electrolyte can be removed, so that the stability of the electrolyte is greatly improved, and the safety and high-temperature performance of the lithium ion battery are improved.

This invention relates to a modified MDI with low temperature resistance and narrow molecular weight distribution and its preparation method. By modifying MDI with carbodiimide and urea-ketimide under high pressure, the content of high molecular weight MDI polymer in the product can be significantly reduced. This not only solves the problem of turbidity in some formulations during downstream applications, but also gives the product excellent low temperature resistance.

The utility model provides a structure for relieving motion sickness fatigue, and belongs to the technical field of life health. According to the utility model, the winding carrier is worn around the eyes, the plurality of semiconductor temperature changing pieces are arranged on one side, close to the eyes, of the winding carrier, meanwhile, the winding carrier is also provided with the air ducts connected to the semiconductor temperature changing pieces, and the fans are arranged in the air ducts, so that the peripheries of the eyes are stimulated through the temperature change when the semiconductor temperature changing pieces work; the generated heat is quickly discharged through the air duct, the influence of motion sickness is relieved in time, fatigue and tension are relieved, the influence of motion sickness is reduced, in addition, temperature change adjustment of the semiconductor temperature changing piece can be directly and electrically controlled, personalized adjustment can be achieved according to different individuals, adjustment is convenient and easy to achieve, and the application range is wide. In addition, stimulation to the periorbital region is a non-invasive natural method, side effects are smaller, response is timely, the intervention effect on motion sickness is better, and application and popularization are facilitated.

The invention discloses a separation method and application of a sheep placenta-derived exosome for treating psoriasis. Application of the sheep placenta-derived exosome in preparation of drugs for treating the following diseases: (1) psoriasis; (2) diabetic foot; and (3) wound healing. When the sheep placenta-derived exosome separated by the separation method disclosed by the invention is used for performing intervention treatment on a C57 wild type mouse psoriasis model, the sheep placenta-derived exosome is found to be capable of remarkably promoting pathological improvement of psoriasis and reducing formation of skin erythema and scurf; skin inflammation and abnormal keratinogenesis caused by the psoriasis are reduced, the effect of improving and treating the psoriasis is achieved, and no obvious side effect exists. In general, the invention can be used as a strategy and means for treating psoriasis.
