BACKGROUND: Decoy receptor 1 (DcR1), which acts as decoy receptors, is resistant to apoptosis induction by related apoptosis inducing ligand (TRAIL). OBJECTIVE: To investigate the expression of the DcR1 (TRAIL-R3) protein in human herniated and normal lumbar intervertebral discs (IVD). METHODS: The expression and distribution of DcR1 proteins were assessed by using immunohistochemistry in 20 herniated lumbar IVD and 8 normal lumbar IVD tissues samples following discoidectomy from January to September 2010. RESULTS AND CONCLUSION: Percentage of nucleus pulposus and anulus fibrous cells with DCR1 expression was obviously more in the herniated group than in normal IVD group. The current results indicate that the expression of DCR1 rises after herniation.

In this paper, duloxetine was chosen as the lead compound. The pharmacophores with 5-HT(1A) antagonism activity were used to replace the naphthyl of duloxetine. A series of duloxetine derivatives had been designed and synthesized and whose structures were confirmed with elemental analysis, MS and H NMR. All synthesized compounds were tested by tail suspension test and forced swimming test in vivo. The test results revealed that most of the compounds have shown better activity than duloxetine at the same dosage. Some of them are worth to be studied further.

OBJECTIVE To study the antidepressant effects of ammoxetine(AMX)and the underlying mechanisms. METHODS Two behavioral despair models,the tail suspension test (TST) and the forced swimming test(FST),were used to evaluate the antidepressant-like effects of AMX 2.5-20 mg · kg-1 following oral administration. Monoamine neurotransmitter p-chloro-phenylalanine(p-CPA)andα-methyl-p-tyrosine(AMPT) depletion models in mice were used to investigate the effects of AMX on levels of 5-serotomin(5-HT)and norepinephrine(NE)in the brain. RESULLTS The results of behavioral study showed that compared with normal control group,AMX(10 and 20 mg · kg-1)reduced the immobility time of mice by 51.4% and 80.7% in the TST(P<0.05,P<0.01) or by 48.0% and 66.2% in the FST (P<0.05),respectively. Locomotion activity test indicated that AMX did not increase or decrease the movement distance of mice,demonstrating that AMX had no excitatory or inhibitory actions on the central nervous system. Moreover,AMX(5,10 and 20 mg·kg-1)exerted antidepressant effects in the p-CPA induced 5-HT depletion model and AMPT induced NE depletion model,as evidenced by the significantly reduced immobility time,ie,63.9%,93.4%,90.5% and 61.9%,77.2%,100% reduction in the TST (P<0.01),respectively,and AMX at the dose of 20 mg·kg-1 significantly increased the concentrations of 5-HT and NE by 144.7% and 57.2% in the mouse brain(P<0.05) ,respectively. CONCLUSION AMX has strong antidepressant-like effects in behavioral despair models and monoamine neurotransmitter depletion models in mice,which is involved in the increased levels of 5-HT and NE in the brain.

OBJECTIVE: To evaluate the clinical therapeutic effect of the combination therapy of traditional Chinese and Western medicines in treating gouty arthritis based on the stage of disease, and to explore a safe, effective and reasonable therapeutic regimen for prevention and treatment of gouty arthritis. METHODS: One hundred and sixty-six cases of gouty arthritis were divided into three groups randomly, 58 cases in traditional Chinese drug (TCD)-treated group, 56 cases in Western medicine (WM)-treated group and 52 cases in TCD plus WM-treated group. They were all treated for 12 weeks. In the acute stage, patients in TCD-treated group were treated with Huzhang Gout Granule and Jinhuang Ointment, and patients in WM-treated group were treated with diclofenac sodium dual release enteric-coated capsules. In the intermission, patients in TCD-treated group were given Yinlian Gout Granule, and patients in WM-treated group were given benzbromarone or allopurinol. Patients in TCD plus WM-treated group were given both TCD and WM. Clinical symptom score and blood uric acid (BUA) level were measured. The effect initiating time, relapse rate, efficacy rate and the incidence rate of adverse effects were also studied. RESULTS: There were no significant differences in the efficacy rate and effect initiating time among the three groups in the acute stage. The clinical symptom score and BUA level were obviously reduced in three groups. In the intermission, BUA level in the WM-treated group and TCD plus WM-treated group were obviously reduced. Although there was a drop tendency in the BUA level in TCD-treated group, there was no statistical difference. The relapse rates in TCD-, WM- and TCD plus WM-treated groups were 12.07%, 26.79% and 9.62%, respectively. There was statistical difference in relapse rates among the three groups (P<0.05). The relapse rate was decreased in TCD plus WM-treated group as compared with those in TCD-treated and WM-treated groups. The average clinical symptom scores during recurrence in the three groups were (10.00+/-3.61), (12.38+/-1.85) and (10.75+/-1.89), respectively. The incidence of adverse effects in TCD-treated group (3.45%) was lower than the other two groups (21.43% and 15.38%). CONCLUSION: The combination therapy of traditional Chinese and Western medicines based on the stage of disease can control the symptoms of gouty arthritis in the acute stage, improve joint function, and can control the BUA level during the intermission, prevent recurrence and relieve the adverse effects.
