  • Publication number: 20140364187
    Abstract: Real-time betting, drawing and winning system and method are provided for a bettor to conduct an online betting service. The bettor is connected to a service server via a user device. The service server generates a lottery number in advance, and generates a verification public key, a signing code and a verification private key according to the lottery number. The bettor selects a betting mechanism, and selects a betting item corresponding to the betting mechanism to generate a betting content. The betting content is compared with the lottery number to generate lottery information. The lottery number and the lottery information are transmitted to the user device. The bettor can identify, by using the verification public key, the signing code and the verification private key, to determine whether the lottery number is identical to the betting content.

  • Publication number: 20060234956
    Abstract: The present invention relates to a series of dicarboxylic acid ester derivatives of ginsenosides such as succinate and glutarate derivatives of 20-O-?-D-glucopyranosyl-protopanaxadiol (compound K, abbreviated as CK), preparation thereof and pharmaceutical uses thereof. The dicarboxylic acid ester derivatives of ginsenosides of the present invention can be used to form pharmaceutical acceptable salts thereof having a high water solubility or can be directly dissolved in an aqueous solution of metal salt, and retain the pharmaceutical activities of ginsenosides such as tumor growth inhibition and cancer preventive cytotoxicity. The dicarboxylic acid ester derivatives of ginsenosides of the present invention are thus suitable for use in the manufactures of various pharmaceutically and cosmetically acceptable dosage forms of preparations, such as peripheral, oral, and topical dosage forms.
