In vitro,platelets are readily activated,which complicates the process of quality control.In con-trast,nanoparticles possess distinct advantages due to their small size,high surface area ratio,biocompatibili-ty,and modifiability.These properties enable them to inhibit platelet aggregation through encapsulation or multi-modification,thereby ensuring the stability of quality control products for clinical platelet assays.This paper delineates the properties of the two existent forms of platelet-nanoparticle complexes,their synthesis principles,and their applications in the medical field.The text goes on to examine the preparation methods of some platelet-nanoparticle complexes and their applications in the fields of cancer therapy,wound healing,and immune disorders.It also explores the potential relationship between platelet-nanoparticle complexes and exo-some-nanoparticle complexes.Additionally,the future research directions of nanoparticles in platelet plasmino-genics are discussed in this paper,emphasizing the effects of nanoparticle concentration,size,and surface modi-fication on platelet aggregation.This provides a theoretical basis for the development of stable and controllable platelet plasminogenics.

Objective: To explore the effects of lipoic acid in the treatment of burning mouth syndrome. Methods : From May 2015 to May 2016, patients with burning mouth syndrome were selected and divided into experimental group (n=14) and control group (n=15). Patients were treated with lipoic acid in the experiment group while oryzanol, vitamin B2 and vitamin were given in the control group. The pain degrees in two groups were compared before and after treatment, and the adverse drug reaction were monitored during the process. Results: Before and after 1 week treatment, there was no statistical difference between VAS scores in two groups (P > 0.05). However, there were significant differences after 2 or 3 weeks (P < 0.05). Improvement of VAS score was found in both groups after treatment (P < 0.05). No adverse drug reaction was found during the treatment. Conclusion Lipoic acid can relieve the pain of patients with burning mouth syndrome.
