ABSTRACT
OBJECTIVE@#To study the antidepressant-like effect and action mechanism of geniposide and eleutheroside B combination treatment on the lipopolysaccharide (LPS)-induced depression mice model.@*METHODS@#Depression mice model was established by lipopolysaccharide (LPS) injection. Totally 48 mice were randomly divided into 6 groups (8 rats per group) according to a random number table, including normal, model, fluoxetine (20 mg/kg), geniposide (100 mg/kg) + eleutheroside B (100 mg/kg), geniposide + eleutheroside B + WAY 100635 (0.03 mg/kg), geniposide + eleutheroside B+ N-methyl-D-aspartic acid receptor (NMDA, 75 mg/kg) groups, respectively. After continuous administration for 10 days, autonomic activity tests after 30 min of administration were performed on the 10th day. On the 11th day, except for the normal group, the mice in the other groups were intraperitoneally injected with LPS (1 mg/kg), and the behavioral tests were performed 4 h later. Enzyme linked immunosorbent assay was used to detect tumor necrosis factor alpha (TNF- α) and interleukin-1 β (IL-1 β) levels in mice serum. The mRNA expression of indoleamine 2,3-dioxygenase (IDO) and nuclear transcription factor (NF- κB) were detected by real-time quantitative polymerase chain reaction. Western-blot analysis was used to detect IDO and NF- κB protein expressions in hippocampus tissue.@*RESULTS@#Compared with the normal group, a single administration of LPS increased the immobility time in the forced swimming test (FST) and tail suspension test (TST, P<0.01), without affecting autonomous activity. Compared with the model group, fluoxetine and geniposide + eleutheroside B administration significantly improved the immobility time of depressed mice in the FST and TST, decreased serum IL-1 β content, inhibited the expression levels of NF- κ B gene and protein in hippocampus tissues (P<0.05 or P<0.01). Compared with the model group, geniposide + eleutheroside B treatment significantly reduced serum TNF-α content and inhibited IDO mRNA and protein expressions in hippocampus (P<0.05 or P<0.01). In addition, NMDA partly prevented the inhibition of IDO mRNA expression by geniposide + eleutheroside B; NMDA and WAY-100635 also partly prevented the reduction of IL-1 ß content induced by geniposide + eleutheroside B treatment (P<0.05 or P<0.01).@*CONCLUSIONS@#The combination of geniposide and eleutheroside B showed a certain antidepression-like effect. Its main mechanism of action may be contributed to inhibiting the activation of NF- κB, decreasing the proinflammatory cytokines such as TNF-α, IL-1 β, and inhibiting in the neuroinflammatory reaction. Additionally, it also affects tryptophan metabolism, reduces the expression of a key enzyme of tryptophan metabolism, IDO. And this antidepressant-like effect may be mediated by 5-hydroxytryptamine and glutamate systems.
ABSTRACT
Objective:To study the effect and related mechanism of Fuyou granule on danazol-induced precocious puberty model in rats. Method:Totally 21 cages of SD female rats were randomly divided into normal group， model group， Leuprorelin（0.1 g·kg<sup>-1</sup>） and Fuyou mixture group（37.9 g·kg<sup>-1</sup>）， and high-dose， mid-dose and low dose Fuyou granule<italic> </italic>groups（17.0，8.5，4.3 g·kg<sup>-1</sup>）. Rats at 5 days of age were given a single subcutaneous injection of 300 μg danazol to establish the precocious puberty model. After 10 days of modeling， drug intervention was started. Vaginal opening was examined at the age of 20 days， and the gonadal development was observed by hematoxylin-eosin （HE） staining. The levels of serum luteinizing hormone （LH）， follicle-stimulating hormone （FSH） and estradiol （E<sub>2</sub>） were determined by radioimmunoassay. The mRNA expressions of hypothalamic gonadotropin releasing hormone （GnRH）， Kiss-1， G protein-coupled receptor 54 （GPR54） were detected by Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR）， and the expression of GnRH cells in the hypothalamus was detected by immunohistochemistry. Result:Compared with the normal group， the vaginal opening of the model group was significantly earlier， and the uterus and ovarian coefficients were significantly increased （<italic>P</italic><0.05）， indicating that the danazol-induced precocious puberty model was successfully established. The expression levels of GnRH， Kiss-1， and GPR54 also increased significantly （<italic>P</italic><0.05）， indicating that the danazol model can activate the HPG axis in advance， thereby inducing precocious puberty<bold>. </bold>Compared with the model group， the mid-dose Fuyou granule group significantly delayed the time of vaginal opening （<italic>P</italic><0.01）， high-dose Fuyou granule group<italic> </italic>significantly reduced uterine wall thickness and uterine coefficient （<italic>P</italic><0.05，<italic>P</italic><0.01）， mid-dose group reduced ovarian coefficient and uterine wall thickness （<italic>P</italic><0.05）. All the three dosage groups of Fuyou granule significantly reduced the content of serum hormones E<sub>2</sub>， LH and FSH （<italic>P</italic><0.05，<italic>P</italic><0.01）， reduced the expression levels of hypothalamic GnRH， Kiss-1 and GPR54 mRNA （<italic>P</italic><0.05）， and decreased the expression of GnRH cells （<italic>P</italic><0.05）. Conclusion:Fuyou granule can achieve therapeutic precocity by regulating the Kiss-1/GPR54 system and down-regulating the expression of GnRH to inhibit the activation of the HPG axis.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of acupuncture on quality of life (QOL) in post-ischemic stroke patients with dysphagia.</p><p><b>METHODS</b>Sixty-six patients with dysphagia were randomly assigned to 3 groups, the 23 patients in the electro-acupuncture (EA) group treated by EA, 18 in the control group received rehabilitation training combined with acupoint percutaneous electric stimulation, and 25 in the acupoint token puncturing (TP) group received rehabilitation training combined with acupoint TP, once every day for 20 days in total. Changes in QOL scale specified for dysphagia of patients before and after treatment were compared.</p><p><b>RESULTS</b>The total effective rate was 69.6% in the EA group, 50.0% in the control group and 64.0% in the TP group with insignificant difference among them (P > 0.05), but the improvements dealing with patients' general condition, time for taking food, frequency of uneasiness, emotion, appetite, social intercourse ability, fatigue, sleep and mental health, etc. in the EA group were superior to those in the other two groups (P < 0.05).</p><p><b>CONCLUSION</b>Acupuncture could improve the QOL of patients with dysphagia after ischemic stroke.</p>

<p><b>OBJECTIVE</b>To evaluate the pre-clinical effect of YJ-XCC1Z3 on the treatment of depression with the mice mouse.</p><p><b>METHOD</b>YJ-XCC1Z3 was administered at the dose of 405 mg x kg(-1) and 135 mg x kg(-1) to observe the locomotor activity with the mouse locomotor activity recorder apparatus, to observe the effect of YJ-XCC1Z3 on the duration of immohility in the mouse forced swimming test and tail suspension test, to observe the effect of YJ-XCC1Z3 on the body temperature and the metabolism of monoamine neurotransmitters in mouse brain in the mouse model of reserpine induced hypothermia, and to observe the effect of YJ-XCC1 Z3 on the times of 5-HTP induced head-twitches in mice.</p><p><b>RESULT</b>There were no significant changes in the locomotor activity, but a significant reduction in the immobility time was observed in the mice treated with YJ-XCC1Z3 405 mg x kg(-1) and imipramine in the forced swimming test and the tail suspension test. YJ-XCC1Z3 135 mg x kg(-1) and 405 mg x kg(-1) could improve the range of reserpine induced hypothermia in mice, and the latter could also enhance the times of 5-HTP induced head-twitches in mice. YJ-XCC1Z3 405 mg x kg(-1) and 135 mg x kg(-1) could increase the content of 5-HT and NE and decrease the ratio of 5-HIAA/5-HT in mouse brain, but the dose of 405 mg x kg(-1) could decrease the content of DA. The dose of 405 mg x kg(-1) could increase the content of 5-HIAA and had no obvious effect on the content of HVA and DOPAC.</p><p><b>CONCLUSION</b>YJ-XCC1Z3 shows potent antidepressant effect by improving the behaviour of the mouse in depression and not inducing hyperlocomotion in the mice. This effect results in the increase of the content of 5-HT and NE in the mouse brain. YJ-XCC1Z3 can decrease the metabolism of 5-HT to effect the content of 5-HT.</p>
