Abstract: A schematic diagram of a portable fan of the present disclosure is shown. The portable fan includes a housing, a substrate, and a fan assembly. The housing includes an accommodating cavity. The housing is further formed with an air inlet communicated to the accommodating cavity. At least a portion of the substrate is arranged on a radial inner side of the housing, and an air outlet is formed between the substrate and the housing. The fan assembly is arranged inside the accommodating cavity and is connected to a rear side of the substrate. The fan assembly includes a motor and a fan blade. The motor is a high-speed motor. A maximum diameter of the substrate is greater than or equal to a maximum diameter of the fan assembly, a front side of the substrate includes a protrusion. The protrusion protrudes forwards out of a front end of the housing.

Abstract: A use of D-arabitol in lipid-lowering and hepatoprotection is provided. Blood or liver lipid abnormalities refer to abnormalities in a quantity and a quality of lipids in the blood or liver, and usually refer to the elevation of cholesterol and/or triglycerides (TGs). Blood and liver lipid abnormalities can lead to atherosclerosis, increase the morbidity and mortality rates of cardio-cerebrovascular diseases, and cause the liver damage. D-arabitol has an excellent lipid-lowering and hepatoprotective effect, and has a prospect of being developed into a drug or health care product or food for lipid-lowering and hepatoprotection.
