Abstract: A pharmaceutical composition, a preparation and a use for treating oral mucosal wounds. The pharmaceutical composition includes a glutamine, s mucoadhesive polymer, and a slow-release polymer. The mucoadhesive polymer is charged polymer. The slow-release polymer is uncharged polymer. Based on the total weight of the pharmaceutical composition, the content of glutamine is 5% by weight to 75% by weight, the content of mucoadhesive polymer is 20% by weight to 70% by weight, and the content of slow-release polymer is 20% by weight to 70% by weight.

Abstract: A deadlock free synchronization synthesizer for must-happen-before relations in at least two parallel programs or at least two threads each having multiple code segments has an input device to specify a synchronization point to involving code segments for each parallel program or thread and must-happen-before relations to the synchronization point, an analyzing module connected to the input device to detect existence of a deadlock in the parallel programs by using the must-happen-before relations, and a synthesizing module connected to the analyzing module to synthesize a practice code corresponding to the parallel programs if the deadlock existence detection is negative.
