ObjectiveTo investigate the effects of Shen-wu capsule on learning and memory ability and its mechanism in APP transgenic mice. MethodsThe APP 695V717I transgenic mice were randomly divided into model group, Shen-wu low dose group (0.4g/kg·d) and high dose group (1.2g/kg·d). Normal control adopted the same age and background C57BL/6J mice. The animals were administered intragastrically by the drug or water from 4 month old to 10 month old. Morris water maze and object recognition test were performed to measure the learning and memory ability. The content of β-amyloid (Aβ) in the brain cortex homogenate was detected with RIA,and amyloid plaques were measured with Congo red staining. ResultsIn the Morris water maze test, swimming time and swimming distance of model group were prolonged distinctly(P<0.01). Shen-wu high dose group obviously shortened swimming time(P<0.05). In the object recognition test, the relative time to the new objection in model group was obviously shorter than that in the control group(P<0.05). The relative time to the new objection for Shen-wu high dose group was obviously longer than the model group(P<0.05). The content of soluble Aβ in model group was higher than that of the control group(P<0.05). Shen-wu group decreased the soluble Aβ distinctly(P<0.01). The amyloid plaques were increased in the brain of model mice(P<0.01). Each group of Shen-wu decreased amyloid plaques significantly(P<0.01).ConclusionShen-wu Capsule ameliorated the learning and memory function disorder and decreased Aβ formation in the brain of APP transgenic model mice.

Objective To explore the effects of 2,3,5,4'-tetrahydroxy stilbene-2-β-D-glycoside(TSG)on the over-expression and aggregation of α-synuclein in vitro.Methods TSG in different concentrations was incubated with α-synuclein transgenic COS-7 cells for 24 h.The cell viability was measured by MTT method.The expression of α-synuclein protein was determined by immunocytochemistry and Western blotting method.Results Incubation of TSG at the range of 12.5～200.0 μmol/L with α-synuclein transgenic COS-7 cells for 24 h did not influence cell viability,but a dose-dependently inhibition for the over-expression of α-synuclein protein could be observed in the tests of immunocytochemistry and Western blotting.Conclusion TSG can inhibit the over-expression of α-synuclein protein in COS-7 cells in vitro.

In our gastroenterology clinic from Jun. 2008 to Jan. 2009, 20. 9% (277/1320) patients were diagnosed with functional dyspepsia (FD) and 14. 8% (41/277) of them with psychological problems according to Minnesota Multiphasic Personality Inventory (MMPI). In those with psychological disorders,92.7% were found with somatization, 60. 9% with depression and anxiety, 97.6% with abdominal pain,75.6% with bloating, 63.4% with early fullness and 36. 6% with nausea. More than 80% patients with anxiety and depression complained irritability, worry, fatigue, poor concentration, memory loss and insomni.a. After 4 weeks of psychological consultation and anti-depression treatment, 5 patients had significant improvement, 31 had improvement and 3 had no response. The overall response rate was 87. 8%.In summary,there is a high prevalence of depression and anxiety in population with FD. Hypochondria and somatization are common among these patients. Psychological consultation with anxiolytic drugs may have good therapeutic effects.

Objective To evaluate the influence of duration of laser irradiation on histomorphometric meas- urements in experimentally tenotomized and repaired rabbit Achilles tendons and to explore the best irradiation time. Methods A total of 20 male New Zealand rabbits aged 10-12 weeks were used and randomly divided into 4 groups:a control group and three experimental groups.All the animals underwent surgical excised and then repair of their Achillis tendon.The animals in the control group were then treated with sham laser irradiation,while those in the three experimental groups were treated with 10,20 and 30 minutes of He-Ne laser irradiation(632.8 nm, 18.9 mW)daily,respectively,for 14 days.On the 28th day after surgical operation,the animals were sacrificed and their Achilles tendons were sampled.HE stain and Van Geison stain were used to observe morphometric changes of tendons.The SDS-PAGE electrophoresis method and CS-930 photodensity scan instrument were employed to measure the content of typesⅠandⅢcollagen.Results it was shown that laser irradiation enhanced cell proliferation,cel- lular content,granulation tissue formation and collagen deposition in laser-treated tendons,especially in those irradia- ted for 20 minute daily,as compared to the control group.TypeⅠand typeⅢcollagen levels were significantly in- creased at the 28th day in the healing tendons and the ratio of collagenⅢtoⅠincreased in all the 3 experimental groups,and the increase of both collagen content and ratio of collagen typeⅢtoⅠwas significantly greater in those ir- radiated 20 minutes daily(P

Objective To research the effects of transcutaneous electrical stimulation (TES) on the expression of neurotrophin-3 (NT-3) and tumor necrosis factor-α (TNF-a) in the ventral horn of rats' spinal cords and in the injured region after spinal cord injury (SCI),and to explore the effects of TES on neuron reconstruction and functional recovery and their mechanisms. Methods Forty-eight Wistar rats were selected and divided using stochastic methods into a model group and a TES group.Using Allen's method,a complete SCI model was created at T9.Rats of the TES group were given TES treatment.Basso-Beattie-Brasnahan ( BBB ) ratings were used to evaluate locomotor function.Both groups were sampled at 1,3,5 and 7 days after the operation.Immunohistochemical techniques were used to detect the expression of NT-3 and TNF-α in the rats' spinal cords at the different time points. Results The post-operative BBB ratings of both groups showed an increasing trend.In the TES group the improvement was significantly better at 5 and 7 days than in the model group.The expression of NT-3 immuno-positive cells increased in both groups,peaking at 5 days post-operation,then declining at day 7.The expression of NT-3 positive cells at days 5 and 7 had increased significantly more in the TES group than in the model group.TNF-α immuno-positive expression increased with time in both groups,but in the TES group the expression increased substantially less than in the model group.At days 5 and 7 post-operation,the expression was significantly lower than in the model group. Conclusions TES can promote NT-3 expression in rats with SCI,inhibit the increase in TNF-α expression,and aid repair and reconstruction of neurons and related functional recovery.

Objective To investigate the relationship between cysteine-rich protein 61 ( Cyr61 ) and phosphatidylinositol 3-kinase ( PI3K ) signal pathway on cell proliferation and apoptotic in human ovarian carcinoma cells.Methods Recombinant human Cyr61 (rhCyr61) was pretreated with ovarian carcinoma cells.The expression of Cyr61 protein was detected by confocal spectral microscopy.Then treated the ovarian carcinoma cells with PI3K transduction inhibitors (LY294002) for 24 hours.Cell apoptosis was detected by flow cytometry (FCM).Cell viability was determined by methyl thiazolyl tetrazolium (MTT) method.The mRNA expressions of Cyr61,the protein levels of protein kinase B ( PKB),phospho-PKB and Cyr61 were assaved by real time-PCR and western blot analysis,respectively.Results The Cyr61 and phospho-PKB protein expression in two ovarian carcinoma cells (OV2008 and OVCAR-3 ) were increased in rhCyr61pretreated group.The decreasing of cell apoptosis [ ( 1.4 ±0.9)％,(2.1 ± 1.0)％ ] and increasing of cell proliferation [ ( 124.0 ± 1.8)％,( 133.0 ±2.2)％ ] was detected in the same time,compared with negative control group,there were significant difference ( P ＜ 0.05 ).After exposed to LY294002 for 24 hours,the apoptosis rate of OV2008 and OVCAR-3 in pretreated with rhCyr61 group exposed to LY294002 were (21.1 ± 1.6)％ and (26.4 ± 1.5 )％,respectively.Cells viability [ (59.0 ± 2.3 )％,(51.0 ± 2.0)％ ]was also significantly decreased in OV2008 and OVCAR-3 pretreated with rhCyr61 cells.Meanwhile,the mRNA expressions of Cyr61 (3.2 ± 0.8,6.2 ± 1.1 ) and the protein levels of phospho-PKB and Cyr61 were greatly decreased.Compared with negative control group,there were significant difference in OV2008 and OVCAR-3 cells (all P ＜ 0.0l ).Conclusions The activation of PI3K intracellular signaling pathways may lead to up-regulation of Cyr61 expression.Block PI3K signal pathway could significantly inhibit the expression of Cyr61,and may promote the apoptotic effects and inhibit the cell growth of ovarian carcinoma cells.
