Disclosed is a method for allocating QKD network resources, which includes the following steps: obtaining a network structure of a QKD network, and constructing a key topology according to distributions condition of quantum key resources in the QKD network; in response to arrival of a service requiring encryption, judging whether the encrypted service is delay sensitive; when the service is delay sensitive, distributing quantum key resources to the service according to the key topology of the QKD network; and when the service is not delay sensitive, distributing quantum key resources to the service according to the network structure of the QKD network. Moreover, the present disclosure also provides a device for allocating QKD network resources and a non-transitory computer-readable storage medium.

Medicinal composition containing ginseng secondary glycosides, its preparation method and application. The present composition contains mainly, as active ingredients, the ginsenoside with protopanoxadiol as aglucone (ginsenoside Rg3) and the ginsenoside with protopanoxatriol as aglucone (ginsenoside Rg2 and ginsenoside Rh1). It is prepared from the ginseng genus of plants through extracting, acid hydrolyzing and using macroreticular resin to separate, purify and concentrate. It is useful in the manufacture of medicaments for treating CHD, angina pectoris, myocardial ischemia, hemorrhagic shock, heart failure, and arrhythmia.

This invention relates to salts of sulfodehydroabietic acid with bismuth or zinc, a kind of new salt useful in treating digestive canal ulcer, acute & chronic gastritis, and erosive gastritis etc., as well as its preparation and use. Said salts can be represented by formula (1), wherein R is Bi(OH)or Zn, 2Bio, 1/2ZnH, n=0&#x2013;10. The preparation method comprises following steps: (a) sequentially treating the industrial abietic acid calcium salt with acid, base and extracting with organic solvent to give abietic acid with less isomer; (b) reacting said abietic acid with Pd/C to provide dehydroabietic acid, then converting it to pure sulphonic product, namely sulfodehydroabietic acid, via sulphonation and recrystallization; (c) by use of neutralization or salt displacement reaction to convert the sulphonic product of zinc or bismuth salts of sulfodehydroabietic acid. The resultant salts can used to prepare medicine for treating digestive canal ulcer and gastritis.
