Integrin is a kind of crucial adhesive molecule on the membrane,and it exerts its function through activating its intra-cellular effectors.One of the most important effectors is integrin-linked kinase (ILK),which is a serine/threonine protein kinase located in focal adhesions and has a key position in transducing many of the biochemical signals.It plays an important roles in regulating fundamental processes such as cell-matrix interactions,growth,proliferation,survival,differentiation,migration,invasion and angiogenesis under both physilogical and pathological processes.

Angiogenesis is a fundamental physiological and pathological process in human body.Angiogenesis is regulated by integrins,a family of cell surface receptors.After binding with their ligands such as extracellular matrix proteins and immunoglobulin superfamily molecules,integrins can promote the proliferation and migration of endothelial cells during angiogenesis.Several integrin-targeted therapeutic agents are currently used in clinical trials for the therapy of angiogenesis related diseases.Here,there will show the roles of integrins in angiogenesis and clinical application.

To understand the present application of gene chip in ischemic brain damage,investigate the application value and the future trends of gene chip technology,the literatures on the application of gene chip in the research of all kinds of ischemic brain damage in the database including MEDLINE,EMBASE,CNKI and VIP were reviewed and comprehensively analyzed.Literatures showed that many differential expressed genes including the significant regulating genes in the pathomechanism and some new neuroprotective genes were found during the application in the research of brain damage including global ischemia,focal cerebral ischemia,and hypoxic ischemic brain damage.Therefore,gene chip has manifested its great application value in the research of ischemic brain damage and deserves a further investigation.

Phosphatase and tensin homology deleted on chromosome 10 (PTEN) is a tumor suppressor with dual protein and lipid phosphatase activity.PTEN is involved multisystem diseases and cancer,though the mechanisms of PTEN regulation are far from clear.Recent advances concerning regulation of PTEN including protein-protein interaction,phosphorylation,ubiquitination,oxidation and acetylation will be discussed.

Phosphatase and tensin homologue deleted on chromosome 10(PTEN) is a tumor suppressor which can inhibit proliferation and migration and control apoptosis in a number of cell types,mainly through inhibiting the phosphoinositide 3-kinase(PI3K) signaling pathway.A number of in vitro and in vivo studies has been instrumental in uncovering a direct correlation between deregulated PTEN/PI3K signaling and changes in neuronal morphogenesis,which is likely to have profound bearings upon the pathogenesis of neurological symptoms.This review outlines recent work on the function of PTEN during the formation and maintenance of neuronal circuits in the brain.

Objective To observe the therapeutic effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type.Methods 60 patients with cervical spondylosis of vertebral artery type were randomly divided into the treatment group and control group with 30 cases in each group. The patients of the treatment group were treated with plum-blossom needle therapy and cupping therapy combined with traction, and those of the control group only with traction. The therapeutic effects of two groups were compared.Results The total effective rate of the treatment group was 83.3 %, that of the control group was 60.0%. There was a significant difference between two groups ( P<0.05).Conclusion The effect of plum-blossom needle therapy and cupping therapy combined with traction on cervical spondylosis of vertebral artery type is superior to traction therapy alone.

Phosphatase and tensin homology deleted on chromosome 10 (PTEN) plays an important role in the proliferation,migration,differentiation,apoptosis and synapse establishment of nervous system.Elucidation of PTEN function is helpful to understand the mechanisms of neural development,and thus may find new therapies for diseases in central nervous system using PTEN as a target.
