To investigate the effects of Shugan Hewei Decoction and its active substance fractions on behavior and neurotransmitter levels in hypothalamus of depression model rats,and preliminarily explore its possible mechanism. Male SD rats were randomly divided into blank control group,model group,fluoxetine( positive control) group,Shugan Hewei Decoction high and low dose groups,high and low dose groups of three different substance fractions. After 3 weeks' CUMS and social isolation to induce models,intragastrical administration lasted for 7 d. Behavioral experiments( sucrose consumption test,open-field test,and forced swimming test) were then performed to evaluate the depression status of rats. Several neurotransmitters in hypothalamus of rats were determined by LC-MS/MS method,including dapamine( DA),norepinephrine( NE),serotonin( 5-HT),5-indoleacetic acid( 5-HIAA),γ-aminobutyric acid( GABA),and glutamic acid( Glu). As compared with the blank control group,the sucrose consumption was reduced( P<0. 01); the total distance and the number of crossing the central area were also significantly reduced( P< 0. 01,P< 0. 01),while the resting time increased significantly( P<0. 01); the forced swimming time was significantly prolonged( P<0. 01); DA,5-HT,NE,5-HIAA and GABA levels in hypothalamus were significantly reduced( P < 0. 01),while Glue level was significantly increased( P < 0. 01) in model group. As compared with the model group,all the above indexes had changes in fluoxetine group,Shugan Hewei Decoction whole recipe groups,volatile oils group,polysaccharides group,and terpenoids group( P<0. 01 or P<0. 05). Shugan Hewei Decoction whole recipe and its active substance fractions can improve the behavior of depression model rats and may exert anti-depression effects by regulating the content of neurotransmitters in the hypothalamus.

To study the antidepressant effect of Shugan Hewei Tang on chronic stress depression model rats, and select the effective substance fractions. Several male SD rats were randomly divided into 17 groups: blank control group, model group, positive control group(fluoxetine), Shugan Hewei Tang high and low dose groups, 6 high and low dose groups of different substance fractions. After modeling for 3 weeks and administration for 1 week, the effective substance fractions were selected according to the body mass and behavioral performance of SD rats in each group; several neurotransmitters in hippocampus of rats were determined by LC-MS/MS method, including norepinephrine(NE), serotonin(5-HT), 5-indoleacetic acid(5-HIAA), r-aminobutyric acid(GABA), and glutamic acid(Glu). Behavioral results after modeling showed that as compared with the blank group, the body mass growth of the model group was significantly reduced(P<0.01); the sugar water consumption was reduced(P<0.01); the distance between the open field and the number of crossing the central area were also significantly reduced(P<0.01, P<0.01); the resting time was increased significantly(P<0.01); and the forced swimming time was significantly prolonged(P<0.01), indicating that the depression model was effective. After intragastric administration, as compared with the model group, the above detection indicators of volatile oils, total polysaccharides and terpenoid in Fluoxetine, Shugan Hewei Tang groups were all changed(P<0.05 or P<0.01). The levels of NE, 5-HT and GABA in the hippocampus of the model group were significantly lower than those in the blank group(P<0.01), and the levels of 5-HIAA and Glu were significantly increased(P<0.01). As compared with the model group, neurotransmitters of the treatment groups were changed obviously or significantly(P<0.05 or P<0.01). Shugan Hewei Tang showed obvious anti-depressant effects, and the volatile oils, total polysaccharides and terpenoids acted as the main active substances. The mechanism of anti-depression may be related to its regulation of various neurotransmitter levels in the hippocampus.

OBJECTIVETo evaluate the effects of acupuncture on post-stroke spastic paralysis.

METHODSA systematic evaluation including all the relavant randomized controlled trials (RCTs) or quasi-RCTs of acupuncture and moxibustion for treatment of post-stroke spastic paralysis were carried out according to the method recommended by the Cochrane Collaboration.

RESULTSNine hundred and seventy-eight patients being included in fourteen papers met the enrolled criteria. However, their methodological quality was relatively poor. Meta-analysis of nine trials indicated that there was no significant difference between the treatment groups and the control groups in Ashworth scores, Carr-Shepherd scores, nerve defect scores and hip adductor tension scores. Whereas the Fugel-Meyer scores in one trial and the Barthel scores in three trials were better in the treatment groups than those of the control group.

CONCLUSIONA reliable conclusion can not be drawn from the present data because of the defects in methodological quality and insufficient numbers of trials, especially lack the long-term terminal outcomes, although it appears a tedency that acupuncture can improve the conditions of post-stroke spastic paralysis. Therefore, it is necessary to perform more multi-central RCTs of high quality in future.
