Abstract: The present invention discloses a series of new compounds containing beraprost and nitric oxide donors, as shown in formula I below, relating to the series of compounds and their pharmaceutical compositions and uses. The invention provides a class of beraprost sodium and NO donor combination drugs, solves the short half-life of clearance problem of beraprost sodium , more daily administration, efficacy of saturation capping effect, and rapid catabolism half-life of NO. The new compound could reduce the dose and frequency, at the same time in-situ generated of NO could induce relaxation smooth muscle effect, through dual action, showcasing the synergistic effect, improving the effectiveness and safety of the drug.

Abstract: The present invention provides a method, an apparatus and a system for realizing communication between blockchains, and the method comprises: receiving a first communication packet sent by a first blockchain, the first communication packet comprising a first transaction, and the first transaction corresponding to a change of a database state on the first blockchain; generating a second communication packet according to the first communication packet; and sending the second communication packet to a second blockchain. In the present invention, the communication between a first blockchain and a second blockchain is realized by receiving a first communication packet including a transaction sent by the first blockchain, generating a second communication packet according to the first communication packet and sending the second communication packet to the second blockchain, and thus the transaction processing capability of a blockchain is improved.

Abstract: A data sharing method includes: reading, by a second participant of a plurality of participants participating in data sharing, first data and a first ring signature from a blockchain; verifying, by the second participant, the first ring signature by using a ring signature verification algorithm according to the public keys of the plurality of participants, the first data and the first ring signature; and using the first data when the second participant verifies that the first ring signature is legal. In the data sharing method according to the embodiments of the present invention, privacy of a data sharer is protected and the data sharer has authority to share data is believed by a verifier, and a responsibility investigation mechanism of the data sharing is established.

Abstract: The present invention provides a method for establishing a personalized association between voice and pattern, comprising: acquiring voice data of a user; converting the voice data into a pattern and storing the pattern; and reading the voice data corresponding to a to-be-queried pattern according to a query instruction of the user. The present invention establishes a personalized association relationship between voice and pattern, and takes the pattern corresponding to the voice as a pattern capable of effectively propagated on the Internet. Moreover, the present invention can form a pattern-voice double medium by converting a pattern into a voice, thus improving propagation range and effectiveness.

Abstract: Present invention teaches a method of producing electric guitar body without the costly and time-consuming process of wood-carving or other traditional woodworking technique. By creating the molds and injecting proper materials, present invention also achieves the 3-D artistic rendition of desired shape for an electric guitar body and at reduced weight than solid wood carving guitar body.
