Evaluation of Clinical Efficacy of Combined Use of Acupuncture and Medicine in Treating Sleep Disorder in Patients with Anxiety Disorder

[Objectives]To evaluate the clinical efficacy of combined acupuncture and medicine in the treatment of sleep disorders in patients with anxiety disorders.[Methods]A total of 300 anxiety patients with sleep disorders were randomly selected and divided into a research group and a control group,with 150 cases in each group.The control group was administered with western medicine,and the research group was treated with acupuncture and medicine to compare their clinical treatment effects.[Results]The total effective rate of treatment in the research group was significantly higher than that in the control group;after treatment,both the PSQI and SAS scores of the two groups were significantly reduced,and the reduction degree of the research group was higher than that of the control group,the difference was statistically significant(P<0.05).[Conclusions]Combined use of acupuncture and medicine to treat sleep disorders in patients with anxiety disorders has better curative effect and fewer adverse reactions,so it has high clinical application value.

Facile synthesis of silicapolymer hybrids via simultaneous RAFT process and hydroxyl-alkoxysilane coupling reaction

This study aimed at the synthesis of silica particles grafted with better-defined homopolymers and block copolymers by tandem approach.Z-functionalized Sbenzyl S’-(3-trimethoxysilyl)propyltrithiocarbonate(BTPT)was used as a couplable RAFT agent to synthesize the target inorganic-organic hybrids.Simultaneous coupling reaction and RAFT process using silica particles and BTPT as raw materials efficiently afforded homopolymers grafted silica,and RAFTsynthesized macro chain transfer agents withω-terminal trimethoxysilane moiety were utilized to mediate graft reaction to prepare silica particles grafted with di-,tri-and tetrablock copolymers comprised of polymer segments such as polystyrene,polyacrylamides and polyacrylates.When the grafted chains had molecular weights ranging between 3920 and 24800 g/mol,the molar grafting ratios,which were dependent on reaction conditions and types and compositions of grafted chains,were estimated to be in the range of 15.2–101μmol/g,and grafted polymers usually had polydispersity indices lower than 1.3,revealing that the grafting process was almost controllable.To the best of our knowledge,this versatile tandem approach is one of the most facile techniques to prepare silica particles grafted with polymeric chains with controlled molecular weight,low polydispersity and precise composition due to its minimal reaction steps,mild conditions,straightforward synthesis and satisfactory controllability.
