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 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.

Purpose The clinical manifestation of primary lymphoma of bone (PBL) is lack of specificity,and it is easy to be misdiagnosed.This study is to investigate the characteristics of ~F-fluorodeoxyglucose (~F-FDG) positron emission tomography/computed tomography (PET/CT) of PBL and to improve the understanding of its imaging findings.Materials and Methods Fourteen patients with PLB (9 males and 5 females) proved by pathology in the Affiliated Hospital of Southwest Medical University from January 2011 to October 2015 were enrolled.18F-FDG PET/CT findings of all the patients were retrospectively analyzed.The CT image,PET image and fusion image were analyzed by 3 physicians of medical imaging.The SUVmax value of the lesion was measured through region of interesting.Results Ten patients with unifocal lesion involved 4 cases of femoral bone,2 cases of pelvis,2 cases of vertebrae,1 case of ulna and 1 case of tibia.The other 4 patients had multifocal lesions.The lesions showed different level of increased radioactivity on the PET imaging with SUVmax of 9.85±4.29.On syn-CT images,6 cases of unifocal PLB showed cribriform or fuzzy boundary insect erosion osteolytic bone destruction,5 of which were accompanied by cortical bone destruction.The other 4 cases of unifocal PLB showed mixed bone destruction.Among the 10 cases of uniffocal PLB,7 of them showed soft tissue masses with unclear boundary and no obvious necrosis or cystic change,1 of them showed pathological fracture and periosteum reaction.The 4 cases of multifocal PBL patients showed multiple osteolytic bone destruction,2 of them had localized soft tissue masses.Conclusion 18F-FDG PET/CT manifestations of PBL have certain characteristics,which is helpful for early diagnosis.It may provide important information for clinical treatment and prognosis evaluation.
