ABSTRACT
Objective To explore the antidepressant effect and mechanism of Chaihu Shugan San (CHSGS) composition, a compound traditional Chinese herb medicine and its components. Methods Rats were randomly divided into 6 groups: normal control group, model control group, a CHSGS group, a component I group, a component II group and a fluoxetine control group. The depression model was replicated by chronic unpredictable mild stress and single house for 28 d. Behavioral scores of the rats were detected by Open-field test and sucrose solution consumption test, and ERK1/2 mRNA expression in the hippocampus tissue was assayed by real-time fluorescent quantitative PCR. Results ERK1/2 mRNA expression was down-regulated in the depression model group compared with the normal control group (P<0.01). Compared with the model group, ERK1/2 mRNA expression in the CHSGS group and fluoxetine group was both up-regulated (P<0.05 or P<0.01); and only ERK1 mRNA expression in the component I group was up-regulated (P<0.05). No significant difference existed between the component II group and the model group (P>0.05). Conclusion Isolated-living condition and chronic mild unpredictable stress can down-regulate the expression of ERK1/2 mRNA in the hippocampus tissue. CHSGS may exert an antidepressant effect through increasing the expression of ERK1/2 mRNA in the hippocampus, component I may play an important role in its antidepression effect, while compatibility of the use of component II can enhance the antidepressant efficacy.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the therapeutic effect and safety of acupuncture at points of The Liver and Gallbladder Meridians for treatment of migraine.</p><p><b>METHODS</b>Multi-central, randomized and controlled trial was used and 253 cases of migraine were divided into an acupuncture group and a western medicine group. The acupuncture group was treated with acupuncture at points of The Liver and Gallbladder Channels with Taichong (LR 3), Yang-lingquan (GB 34), Fengchi (GB 20), Ququan (LR 8) selected as main points, and the western medicine group with oral administration of Flunarizine tablets for 4 therapeutic courses. The total therapeutic effects 3 and 6 months after the treatment, the scores of various symptoms of migraine before and after treatment, and the stability of therapeutic effect in one-year following-up survey were observed in the two groups.</p><p><b>RESULTS</b>After treatment, mean times and duration of the headache attack were significantly improved in the two groups (all P < 0.01) with the acupuncture group better than the western medicine group (P < 0.05). The total effective rates for stopping pain after treatment, 3 months and 6 months after treatment in the acupuncture group were 93.0%, 93.0% and 87.7%, respectively, which were better than 85.6%, 86.5% and 69.2% in the western medication group (all P < 0.01). One year later, the stability of the therapeutic effect in the acupuncture group was better than that in the western medicine group (P < 0.05); the adverse reaction and the compliance in the acupuncture group were significantly superior to those in the western medicine group.</p><p><b>CONCLUSION</b>Acupuncture at points of The Liver and Gallbladder Meridians for treatment of migraine is safe, effective, and with stable long-term therapeutic effect.</p>

OBJECTIVE@#To examine the differential expression of protein of thalamus in rats with diffuse axonal injury.@*METHODS@#Twenty-five rats were randomly divided into a normal group (n=10) and a trauma group (n=15). Total proteins of brain trauma tissue and normal brain tissue were extracted separately, and then proteins were separated by two dimensional gel electrophoresis and stained with Coomassie brilliant blue. The differentially expressed protein spots were identified with biospectrometry. Images were analyzed by PDQuest 7.0.@*RESULTS@#The distribution of protein spots in the trauma group was similar to that of the normal group, the matching rate was 95%, and the repeatability was good. Proteins were mainly displayed at pI 3-8, with relative molecular mass 14.4-75.0 kD. Compared with the normal group, 16 spots of proteins increased and 18 spots of proteins decreased in the trauma group.@*CONCLUSION@#There is some difference in protein expression between the normal group and the trauma group. Brain trauma may lead to changes of proteins in the thalamus.
