This review focuses on the association of the anoikis with instability and rupture of atherosclerotic plaque.

Central nervous system(CNS) disease induces functional deficits in persons.Simultaneously,there appears axonal destruction and the formation of scar tissue,as well as cavity and physical gaps in the lesions.Olfactory ensheathing cells(OECs),acting as prime candidates for autologous transplantation,secrete neurotrophic factors for neuroprotection,angiogenesis and outgrowth of both intact and lesioned axons to different degrees,change the response status of endogenous glia after lesion,as well as remyelinate axons after a range of demyelinating insults.OECs transplantation has become an ongoing clinical therapeutic approach for human CNS disease in recent years.Thus,OECs transplantation can be used for cell-mediated repair following a variety of CNS lesions.Here,the paper reviews the current status of foundational research of OECs transplantation in treating CNS disease underlying the wide variation of results obtained in the field.

Objective To study the frequency of lymphocyte cells in hypertrophic adenoid in children with otitis media with effusion. Methods The study group consisted of 45 children suffering from hypertrophic adenoid coexisting with otitis media with effusion (HA/OME). The control group consisted of 34 children with adenoid hypertrophy(HA),but without otitis media. Adenoids excision was implemented. Cells were stained with fluorescently labeled protein-specific antibody. The lymphocyte of adenoids was determined by flow cytometry. Results Lymphocyte cells(CD3+CD4+CD69+T cells(1.29%),CD3+CD4+HLA-DR+T cells(0.61%),CD3+CD8+CD69+ T cells (1.39%),CD3+CD8+HLA-DR+ T cells (0.09%),CD19+CD69+ B cells (2.07%) and CD19+CD62L+B cells(0.21%)in HA/OME group were higher than in HA group:(CD3+CD4+CD69+T cells(1.94%), CD3+CD4+HLA-DR+T cells(0.84%),CD3+CD8+CD69+T cells(2.08%),CD3+CD8+HLA-DR+T cells(0.18%), CD19+CD69+ B cells (3.98%),CD19+CD62L+ B cells (0.46%). In addition ,there are the higher percentage lymphocyte cells(CD3+CD4+ T cells(8.97%),CD3+CD8+ T cells(4.27%),CD3+CD8+ Fas+ T cells(1.24%) and CD19+Fas+ B cells (3.23%) in HA/OME group than those in HA group:(CD3+CD4+ T cells (6.37%), CD3+CD4+CD69+ T cells (1.29%),CD3+CD4+HLA-DR+ T cells (0.61%) and CD3+CD8+ T cells(3.61%). Conclusions The local immune dysfunction resulting from hypertrophic adenoids may have a relationship with otitis media.
