ABSTRACT
AIM:To explore the effect of acteoside on behavioral changes and endoplasmic reticulum stress(ERS)in prefrontal cortex of depressive rats.METHODS:Sprague-Dawley(SD)rats(n=108)were randomly divided into 6 groups:control group,model group,fluoxetine(20 mg/kg)group,low-dose(30 mg/kg)acteoside group,medium-dose(60 mg/kg)acteoside group and high-dose(120 mg/kg)acteoside group,with 18 rats in each group.The depres-sive-like rat model was established by chronic unpredictable mild stress(CUMS)combined with solitary way for 28 d.The rats in fluoxetine group and acteoside groups were treated with fluoxetine(20 mg/kg)or acteoside(30 mg/kg,60 mg/kg and 120 mg/kg)once daily by intragastric administration for 3 weeks.The rats in control group and model group were both given equal volume of saline by intragastric administration for 3 weeks.The behavioral changes were detected by the open-field test and sugar preference experiment.The protein expression of glucose-regulated protein 78(GRP78 )and C/EBP homologous protein(CHOP)was assessed by immunofluorescence and Western blot.The caspase-3 activity was measured by spectrophotometer.RESULTS:Compared with control group ,the total distance ,time spent in the center and sugar in-take were all decreased ,the expression of GRP78 and CHOP was increased ,and the activity of caspase-3 was increased in model group ,fluoxetine group and acteoside groups(P<0.05 ).Compared with model group ,the total distance ,time spent in the center and sugar intake were increased ,the expression of GRP78 and CHOP was reduced ,and the activity of caspase-3 was decreased(P<0.05)in fluoxetine group and acteoside groups.CONCLUSION:Acteoside improves de-pressive-like behaviors in depressive rats ,which may be related to the inhibition of ERS and neuronal apoptosis in prefron-tal cortex.
ABSTRACT
@#Objective To observe the effect of stellate ganglion block on patients with cerebral infarction.Methods36 patients with cerebral infarction were randomly divided into the control group and research group.Both two groups were treated with traditional treatment.The research group was added with stellate ganglion block.ResultsAfter 20 days treatment,the Neuro-function Deficit(NFD) scores of both two groups were significantly lower than that before treatment(P<0.01);but the NFD scores of the research group were significantly lower than that of the control group(P<0.01).The scores of Fugl-Meyer Assessment(FMA) and Barthel Index(BI) of both two groups were significantly higher after treatment(P<0.01);but the scores of FMA and BI of the research group were significantly higher than that of the control group(P<0.01).ConclusionStellate ganglion block can improve the nerve function of patients with cerebral infarction.
