The invention relates to a synthesis method of urophosphoryl in citicoline injection, which comprises the following steps: a, adding uridine disodium monophosphate, dicyclohexylcarbodiimide, morpholine and a solvent into a reaction container, heating for reaction, and cooling for suction filtration; b, adding choline chloride phosphate calcium salt into the obtained filtrate, adjusting the pH value to an acidic condition, heating to react, and carrying out suction filtration after full reaction; and c, leaching the obtained filter cake by using a solvent, and drying to obtain urocholine. The synthesis method provided by the invention can be used for preparing the urinary phosphorylcholine, and citicoline with higher purity can be obtained through research and analysis of the urinary phosphorylcholine.

Message distribution method and terminal in high throughput environment

Номер: CN116032866A

The invention discloses a message distribution method and terminal in a large throughput environment, and the method comprises the steps: obtaining a to-be-pushed message of a message push processing table, and obtaining a receiver device of the to-be-pushed message; and judging whether the number of receiver devices of the to-be-pushed messages is greater than a set threshold, if so, performing message pushing on the to-be-pushed messages in batches, otherwise, performing message pushing normally. By processing the data in batches and setting the upper limit threshold value of each batch of the data in batches, the number of threads in operation cannot be too small, the exertion of a hardware function cannot be affected, the situation that the calculated amount of thread scheduling is too large and the probability of deadlock is too large is also prevented, and the operation efficiency and stability of a message distribution mechanism in a large-throughput environment are improved.
