Objective To explore the effects and safety of citalopram combined with low-dose risperidone on refractory depression. Methods All of 54 patients with the refractory depression were ran-domly divided into two groups: augmented treatment group (taken citalopram 20 mg/d, risperidone 0.5-2.0mg/d) and mono-thempy group (taken citalopram alone 20 mg/d). The treatment lasted for 6 weeks. They were estimated with Hamilton depression scale (HAMD), Hamilton anxiety scale (HAMA), and treatment emergent symptom scale (TESS) at baseline and every two weeks subsequently. Results In the augment-ed treatment group, total effective rate was 60.7% and recovery and excellence rate was 50.0%, while that was 26.9% and 15.4% in mono-therapy group (P< 0.05). The adverse effect of two groups was minor. Conclu-sion Rispefidone may be a useful and safe adjunct to citalopram in treatment of refractory depression.

Objective To investigate the anti-fatigue mechanism of Relieving Fatigue Decoction(RFD). Methods 33 male SD rats were evenly randomized into control, model and RFD groups. 21d exhausted swim exercise was used to make an exercise-induced fatigue rat model. RFD group was given RFD in routine doses by gastric perfusion for 21d, once a day. After decapitation, the rats’ testis, liver and blood were taken, detecting MDA with thio-barbituric acid method, GSH and GSH-PX with chromatometry method, SOD with xanthine oxidase method, testosterone and corticosterone with ELISA method respectively. Results (1)Compared with control group, the serum MDA in model group increased significantly(P0.05); the testis, liver and serum GSH, GSH-PX reduced significantly(P0.05); the serum testosterone and corticosterone increased significantly(P0.05); the testis, liver and serum GSH increased significantly(P0.05); the liver SOD increased significantly(P0.05); the serum corticosterone decresed significantly(P0.05).Conclusion RFD may improve the activity of antioxidant enzymes in liver, testis and serum, and raise serum T/C level, which may underlie its action in impoving fatigue.

Results One pterocarpan, (6aR, 11aR) 9, 10-dimethoxypterocarpan-3-O-?-D-glucopyanoside (Ⅴ) and four isoflavones, formononetin (Ⅰ), calycosin (Ⅱ), formononetin-7-O-?-D-glucopyanoside (Ⅲ), and calycosin-7-O-?-D-glucopyranoside (Ⅳ) were identified. Conclusion All five compounds were isolated for the first time from BHT.

Objective To explore the effect of different frequencies interference of electoracupuncture on acute stress of C57BL/6 mice. Methods Thirty male C57BL/6 mice were randomly divided into model group,2Hz electroacupunture group and 100 Hz electroacupunture group.After interfering 7 days by electroacupuncture,all the mice were carried forced swimming tests and tail suspension test,and the immobility time in 5 minutes were taken down. Results The immobility time of forced swimming test and tail suspension test of 2 Hz eletroacupuncture group(32.00±14.73)s,(72.50±20.44)s was shorter than those of 100 Hz electoracupuncture group(145.60±34.62)s,(124.22±21.67)s( P <0.05); and the immobility time of 2 Hz eletroacupuncture group was shorter than that of model group(129.50±33.94)s,(142.23±20.05)s( P <0.05); but the immobility time of 100 Hz electroacupuncture group was no difference with that of model group( P >0.05). Conclusions The effect of 2 Hz eletroacupuncture could improve the behaviors of the acute stress of C57BL/6 mice and had the more effectiveness on anti-depression.

Object To study the isomers of amygdalin in BUYANG HUANWU TANG and its production Methods Amygdalin was isolated from both peach seeds and BUYANG HUANWU TANG by using various column chromatography Their structures were identified by the various spectral data Results Amygdalin had been isolated from n BuOH fraction of aqueous extract of BUYANG HUANWU TANG and found to be a pair of D , L epimers and their ration was 1∶1 It was also found that the structures and the ration of D , L epimers of amygdalin in decoction of single peach seed were similar to that in BUYANG HUANWU TANG. The peach seed only gave D amygdalin when it was extracted in 95% EtOH at reflux temperature, and D amygdalin cannot be isomerized when it was treated in water at 100 ℃ Conclusion Isomerization of D amygdalin results from interaction between it and other compounds of peach seed in water at high temperature, and has no evident relation to other constituents in BUYANG HUANWU TANG L amygdalin is a new compound generated due to decoction of peach seed

Objective To study the antithrombotic compounds and bioactive fraction from Buyang(Huanwu) Decoction(BHD).Methods Four alkaloids have been isolated from BHD by repeated chromatographies.Their structures were elucidated by means of spectral and single-crystal Xray diffraction analysis.Results They are N-(3′-maleimidyl)-5-hydroxymethyl-2-pyrrole formaldehyde(Ⅰ),4-carbamoyl-2-pyrrole carboxylic acid(Ⅱ),N-(1′-D-deoxyxylitolyl)-6,7-dimethyl-1,4-dihydro-2,3-quinoxalinedione(Ⅲ),and 2,3,4,9-tetrahydro-1H-pyrido indole-3-carboxylic acid(Ⅳ).Conclusion All these compounds are isolated from BHD for the first time and compounds Ⅰ-Ⅲ are new alkaloids.

p70 ribosomal protein S6 kinase (p70S6K), an important member of AGC family, is a kind of multifunctional Ser/Thr kinases, which plays an important role in mTOR signaling cascade. The p70 ribosomal protein S6 kinase is closely associated with diverse cellular processes such as protein synthesis, mRNA processing, glucose homeostasis, cell growth and apoptosis. Recent studies have highlighted the important role of S6K in cancer, which arose interests of scientific researchers for the design and discovery of anti-cancer agents. Herein, the mechanisms of S6K and available inhibitors are reviewed.

Objective To evaluate the early effect of leukocyte-and platelet-rich fibrin (L-PRF)on tendon-bone healing in rabbits' extra-articular bone tunnel.Methods Thirty healthy New Zealand rabbits were randomly divided into an experimental group and a control group,each of 15.The semitendinosus tendon harvested from the hind leg of each rabbit was prepared as free autografts.Each autograft was implanted into the bone tunnel created at ipsilateral proximal tibial metaphysis.The experimental group was added with autologous peripheral blood-derived L-PRF,while the control group did not add anything.Speciments from each group were harvested at 4,8 and 12 weeks after operation.The morphological changes were observed and evaluated at each time point.The fibroblasts on the tendon-bone interface were counted and analyzed under the high magnification microscope.Results The number of fibroblasts between the tendon and bone in the experimental group was significantly higher than that of the control group at each time point (P＜0.05).And the connection between tendon and bone was closer and the collagen fibers were more regular in the experimental group than the control group at each time point.Sharpey's-like fibers which marked the early healing of the tendon to bone,were observed at 4th week in the experimental group,while they were observed at 8th week in the control group.As the healing time extended,Sharpey's like fibers continue to increase in both groups and significant differences were observed in the histological morphology (Buark grades)between the two groups (P＜0.05).Conclusion Autologous peripheral blood-derived L-PRF can promote early healing of autologous tendon to bone in the extra-articular bone tunnel of model rabbit.

OBJECTIVE: To evaluate the efficacy and ADR of palipeddone sustained release tablet in the treatment of schizophrenia in outpatient. METHODS: Outpatients with schizophrenia treated with palipeddone sustained release tablet(observation group) in our hospital from Apr. to Sep. in 2009 were followed up and compared with those treated with risperidone(control group) during the same period. PANSS and TESS were applied to evaluate efficacy and ADR. RESULTS: The cure rates were 42.4% for control group and 49.6% for observation group. The effective rates were 74.8% for control group and 80.3% for observation group (P
