Objective To explore the effect of bone marrow mesenchymal stem cells (MSCs) on LPS-stimulated BV2 microglia in inflammatory reaction. Methods Mouse MSCs were isolated and purified by adherence screening. The routinely cultured BV2 microglia in vitro were divided into PBS control group (group A),PBS plus MSCs treatment group(group B),LPS stimulation group(group C) and LPS plus MSCs group(group D).MSCs and BV2 microglia were cultured in the transwell co-culture system for 24 hours. We observed BV2 microglia morphological changes under the microscope,detected the concentrations of NO by Griess reaction,and the level of IL-1β,TNF-αby ELISA. Results MSCs can improve the morphology of activated microglia. The concentrations of TNF-a, IL-1βand N0 in culture supernatants were increased significantly (P < 0.05) after microglia activation, however, at the present of MSCs,the concentration of these inflammatory factors declined dramaticly (P<0.05). Conclusions MSCs can significantly inhibit the activation of microglia. It may play a neuroprotective effect by reducing the inflammation of microglia. MSCs showing anti-inflammatory effects through non-direct contact with nicroglial, suggesting that MSCs outside the brain may also inhibit the activation of microglia.

AIM: To study the clinical efficacy and safety of venlafaxine in the treatment of depression.　METHODS: One hundred and thirty-one patients with depression were randomly divided into 3 groups: venlafaxine group of 43 patients (M23, F20; age 39 a± s 12 a) was treated with venlafaxine, 25-100 mg, po, bid for 6 wk; imipramine group of 43 patients (M 21, F 22; age 38 a±11 a) was treated with imipramine, 25-75 mg,po, bid for 6 wk; sertraline group of 45 patients (M 25, F 20; age 40 a±12 a) was treated with sertraline, 50-100 mg, po, qd for 6 wk.　RESULTS: The total clinical effective retes were 88% for venlafaxine group, 91% for imipramine group and 89% for sertraline group (P>0.05). The adverse reactions in venlafaxine group were lower than that in imipramine group, but were higher than that in sertraline group.　CONCLUSION: Venlafaxine is a safe and effective drug for treatment of depression.

Objective To improve the therapeutic response and survival of locally advanced pancreatic cancer treated with radiochemotherapy. Methods Fifty nine patients with stage Ⅱ Ⅲ pancreatic cancer were divided into two groups: 33 patients were treated with three dimensional conformal radiotherapy (3DCRT) plus regional intra arterial infusion chemotherapy (CT)and 26 patients received 3DCRT alone.Results The response (pain alleviating) rates were 78.8% in 3DCRT+CT group and 80.8% in 3DCRT group,while the overall response (CR+PR) rates were 78.8% and 42.3% (P

AIM: To quest the relationship bwteen BDNF and seizures. METHODS: BDNF and other correlative proteins in the hippocampus of audioepileptic rat (P77PMC) have been detected by immunohistochemistry at different stages of seizures including quiet stage, preconvulsive stage, convulsive stage and postconvulsive stage. Wistar rats were served as controls. RESULTS: At quiet stage, the BDNF in the hippocampus of P77PMC were less than that of control group and stepped up after stimulation, trkB in the hippocampus of P77PMC were high at every stages, but PY20 were increased only after stimulation. NPY in the hippocampus of P77PMC were in a low level before seizures. CONCLUSION: The endogenetic BDNF may alter the excitement of P77PMC by adjusting the expression of NPY in hippocampus and activating its receptor trkB.

Objective To observe the protection effect of thrombopoietin on adriamycin-inducod acute myocardium injury in rats model.Methods 32 Wistar rats were randomized into four groups (n=8):Control group,ADM group,ADM +TPOL group and ADM +TPOH group.All agents were given by intraperitoneal injection.The control group was given normal saline,while the other three groups were given adriamycin at the dosage of 20 mg/kg once.TPO groups were injected TPO at different dosages of 10 μg/kg or 30 μg/kg three times on alternate days.ELISA was used to detect CK-MB and cTnI content of serum in the rats.By HE staining,pathological change was found and grade of tissue morphology was scored.The ultrastructure change of cadiocyte was observed by the electron microscope.Results The energy of CK-MB (14.65±1.91,14.21±1.70) and cTNI (9.66±1.31,10.07±1.20) in TPO groups were obviously lower than that of the ADM group(19.58±3.49,12.50±1.62) (P<0.05),respectively.Pathological score of ADM group was higher than TPO groups (P<0.01).The ultrastructure of myecard tissue in the ADM group was damaged more severely than TPO groups.Above-mentioned indexes were with no significant difference between ADM+TPOL group and ADM+TPOH group.Conclusion TPO can protect the heart which was injured by the ADM.
