A method and apparatus for mitigating health risk from cell phone usage wherein a cell phone having a source of radiation generating excitatory radiation toward brain tissue and an earphone electrically connected to the cell phone via a cord of sufficient length to permit the cell phone to be located more than ten inches from brain tissue during operation of the cell phone. An automatic shutoff mechanism preventing operation of the cell phone unless the cord is extended at least ten inches whereby the excitatory radiation is at a sufficient distance from the brain tissue to prevent brain tissue damage from the excitatory radiation.

The invention discloses application of curcumin to preparation of drugs for treating cerebral ischemia / reperfusion injuries, belonging to the technical field of drug preparation. A cerebral ischemia / reperfusion injury model is prepared and curcumin-PVP (polyvinylpyrrolidone) solid dispersions are used for treating the disease model after being dissolved with the saline for injection. Results show that curcumin can obviously improve the injuries of vital organs such as distant livers and kidneys caused by cerebral tissue injuries and cerebral ischemia / reperfusion injuries and can control the expression levels of several factors related to apoptosis, inflammations and oxidation, control further aggravation of the injuries and protect the vital organs such as cerebral tissues and livers and kidneys.

An application of the brasileiin in preparing the medicines for treating the cerebral ischemia, encephalorrhagia and the cerebral disfunction caused by excessive peroxide in cerebral tissue is disclosed.

The invention discloses application of salvianolic acid C in preparing ischemic stroke resistant drug and / or healthcare products. The invention finds that the salvianolic acid C can remarkably improveneurobehavioral defect symptoms of cerebral ischemia-reperfusion rats, lower cerebral infarction volume and cerebral edema of the cerebral ischemia-reperfusion rats and reduce opening degree and permeability of rat blood brain barrier. The salvianolic acid C can be used for preparing the drug and / or the healthcare products for treating ischemic stroke, brain tissue nerve cell apoptosis can be reduced, survival rate of nerve cells can be increased, brain tissue injury degree can be lowered, and an effective solution is provided for disease prevention and treatment.

The invention relates to application of a salvianolic acid A composition in preparing medicines for protecting ischemic brain tissue damage. The composition is prepared from the following components in percentage by weight: 90-99% of salvianolic acid A, 0.1-3% of alkannic acid, 0.1-3% of rosmarinic acid, 0.1-3% of salvianolic acid B and 0.1-5% of salvianolic acid C.

The invention discloses functional mandulapalka milk rich in crocin and iridoid glycoside and a preparing method thereof. The functional mandulapalka milk is composed of, by weight, 1-10 parts of gardenia milk pulp, 1-9 parts of mandulapalka milk pulp and 1-3 parts of tea pulp. The gardenia milk pulp is composed of, by weight, 10-20 parts of gardenia powder and 80-90 parts of water. The gardenia powder is prepared by at least one of gardenia whole fruits, gardenia florida and skim gardenia meal. The mandulapalka milk pulp is composed of, by weight, 10-20 parts of mandulapalka powder and 80-90 parts of water. The mandulapalka powder is prepared by mandulapalka and / or skim mandulapalka meal. The tea pulp is composed of, by weight, 1-5 parts of tea and 95-99 parts of water. The functional mandulapalka milk contains protein, unsaturated fat and other nutritious substance, the health care functions of the crocin and iridoid glycoside in gardenia can be fully utilized, and the functions of being resisting to depression, preventing nerve cell and brain tissue damage and improving the heart and cerebral vessel functions and cognitive ability of middle-aged and aged people are achieved.

The invention provides calcium silicate nano hollow microsphere modified thermosensitive hydrogel and a preparation method and application thereof. The preparation method includes: preparing calcium silicate nano hollow microspheres, dispersing the microspheres in the complex solution of carboxymethyl chitosan and beta-sodium glycerophosphate, and processing at 30-70 DEG C. The preparation methodhas the advantages that the method is simple and low in cost, the reaction conditions of the method can be achieved easily, and the raw materials used by the method are cheap and easy to obtain; the prepared thermosensitive hydrogel is safe, low in cytotoxicity, good in biocompatibility and good in low-temperature flowability, the hydrogel can fast turn into gel at 37 DEG C, the surface of the gelis loose and porous, and the gel is large in specific surface and capable of benefiting neural stem cell adsorption; the calcium silicate nano hollow microspheres are evenly dispersed in the thermosensitive hydrogel, and the thermosensitive hydrogel can promote neural stem cell differentiation; when the thermosensitive hydrogel is applied to brain tissue damage repairing, neural stem cell adsorption can be promoted effectively, the neural stem cells can be effectively promoted to differentiate into neurons and neuroglia, and the thermosensitive hydrogel is promising in clinical application prospect.
