Abstract: The invention relates to fat emulsions, particularly to a use of high-concentration glycerol in freeze-thaw resistant emulsions and a free-thaw resistant emulsion thereof. The said high-concentration glycerol is the glycerol that is greater than or equal to 3 w/v % in the emulsion composition. The maximum percentage of the glycerol in the emulsion is 50 w/v %. When the percentage of the oil in the emulsion is 2%-30 w/v %, the glycerol is more than or equal to ? of the oil in the emulsion. The invention comprises a drug-contained emulsion through including drugs. Compared with prior arts, the invention provides a freeze-thaw resistant emulsion which tolerates the low-temperature freeze-thaw experiments, avoiding the pharmaceutical stability issues due to the temperature changes during the emulsion transport, storage and utilization, ensuring medicine quality, meanwhile it drastically reduces the requirements of the transport and storage conditions as well as the medicine costs.

Abstract: A protein-phospholipid dispersion preparation in a drug delivery system is provided, in which the weight ratio of protein to phospholipid is 1:300-300:1 and the particle size is between 5 nm and 1000 nm. The preparation process of the said preparation contains the mixture of protein phase and phospholipid phase and the homogenization process. The said drug delivery system can be used in many different pharmaceutical agents.

Abstract: A composite emulsifier, contains two or more emulsifiers selected from phospholipid, PEG emulsifier and poloxamer-like substance, and may contain cryoprotectant. An emulsion prepared from the composite emulsifier and a preparation method of the emulsion.

Abstract: The invention discloses an information switch, which comprises a management system, a core switching system and an information routing system. The core switching system at least comprises an information bus, a switching module and a switching management module. The information bus comprises an access bus (D-Bus) for connecting with device access gateways, a service bus (S-Bus) for connecting with service gateways, a management bus (M-bus) for connecting with the management system, and a routing bus (R-Bus) for connecting with the information routing system. The management system and the information routing system are connected with core switching via the information bus to perform, respectively, system management and routing management.
