摘要:
Nitroglycerine, the classic drug for myocardial ischemia, has been used over a century. By providing exogenous No., it alleviates the myocardial ischemia and is mainly used in the first aid of myocardial ischemia. The 4-Medicinal-Plant-Derived Coronary Blood Flow enhancing Agent is the result of strictly controlled processing procedures including the followings: extracting with Carbon Dioxide Supercritical Fluid; WLD resin adsorbing, eluting, separating and purifying; high performance liquid chromatography and fingerprint analysis to ensure the balanced and stable quality. Pharmacological experiments indicated that it increased coronary blood flow, lowered peripheral vascular resistance, regulated myocardial oxygen supply-demand balance and decreased the oxygen consumption index as well as myocardial oxygen consumption. It takes effect in a way different from Nitroglycerine. This agent can be used for the prevention and treatment of myocardial ischemia, coronary heart disease and angina pectoris.

摘要:
A system for maintaining network information. The system resides in a network comprising a plurality of sub-networks in communication with one another over a communications backbone. Each sub-network has a router for use in performing communications with other sub-networks. A directory service is linked to the communications backbone and includes a database. The database stores router attribute information that is published by each of the routers. Using a query engine associated with the directory service, meaningful information can be gathered from the database as a function of specified router attribute information.

The invention relates to an enteric-coated capsule containing cationic nanoparticles for oral insulin delivery, in particular to a type of cationic nanoparticle including a polycationic and mucoadhesive polymer and a biodegradable polymer, wherein each of the nanoparticles has positive surface charge and enhanced permeability for paracellular insulin delivery; the enteric-coated capsule further includes a pH-sensitive polymer as the coating. The enteric-coated capsule containing cationic nanoparticles, when being orally administered to a subject, are configured to prevent the acidic degradation of the active substance such as insulin before being released from said cationic nanoparticles to a specific absorption site along the gastrointestinal tract.
摘要:
A direct polycondensation method for medical biodegradable polylactic acid (PLA). The invention uses commercialized creatinine (a type of biomaterial organic guanidine compounds—the arginine metabolite creatinine in human body) as the catalyst and industrial lactic acid (mass content 85-90%, aqueous solution) as the monomer to synthesize the PLA in terms of second polycondensation without solvent. Instead of tin catalysts having cytotoxicity, the catalyst used in the invention has high biocompatibility and biosafety. The synthesized PLA does not contain any metal and other toxic components; therefore, it can be used as the carrier for targeting drugs and controlled release drugs. The green catalyst and green processing method (no solvent applied and no toxic products produced) are used to synthesize the green biodegradable PLA with high biosafety. The molecular weight distribution for all synthesized products is narrow and the molecular weight is controllable within 1.5-3.0×104.

Scalable session management is achieved by generating a cookie that includes an encrypted session key and encrypted cookie data. The cookie data is encrypted using the session key. The session key is then signed and encrypted using one or more public/private key pairs. The encrypted session key can be decrypted and verified using the same private/public key pair(s). Once verified, the decrypted session key can then be used to decrypt and verify the encrypted cookie data. A first server having the private/public key pair(s) may generate the cookie using a randomly generated session key. A second server having the same private/public key pair(s) may decrypt and verify the cookie even if the session key is not initially installed on the second server. A session key cache may be used to provide session key lookup to save public/private key operations on the servers.
