International Journal of Biomedical Engineering 2008;31(2):102-106
Penis is one of the most important components of male external genitalia.Congenital abnormalities and trauma may lead to genitourinary organ damage or default,which require reconstruction.With the development of tissue engineering(TE),penile corpora cavernosa tissue engineening has becoming the core of the penis reconstruction.Recent researches mainly focus on forming scaffolds and transplanting cells(including of endothelial cells and caveruosal smooth muscle cells). Recently, stem cell technology, gene therapy and nervous reconstructive techniques have been combined to promote the development of tissue engineering.Tissue engineering has been thought to be able to make possible the restoring and constructing of the structure and normal funetion of penile corpora cavernosa.This paper gives a review of the recent progress in associated researches on tissue engineering of the penile corpora cavernosa.
2.Research Advances in Baculovirus Occlusion-derived Virions.
Chinese Journal of Virology 2016;32(1):93-100
Baculoviruses are a family of arthropod-specific viruses that produce two morphologically distinct types of virions (budded and occlusion-derived) in their lifecycle. Baculoviruses establish infection in the midgut of their host via the oral route: occlusion-derived virions have pivotal roles in these processes. This review summarizes the basic characteristics of baculoviruses, and discusses the composition and classification of baculovirus occlusion-derived virions. The latter focuses mainly on the evolution and role of multiple occlusion-derived virions in the lifecycle of baculoviruses. These achievements should aid understanding the evolution and infection mechanisms of baculoviruses.

The adherent state of oxide layer on the surface of substrate alloy was observed .Results:The oxide layer on the surface of alloy had stable thickness and contain ed more and more oxide as porcelain firing times increased.In some area,oxide la yer fractured from the substrate metal.Conclusion:Cobalt-chromium alloy frame should be abrased and polished thoroughl y after porcelain bake cycles.
4.The Present Status of Reseach on Varicella-zoster Virus Infection
Chinese Journal of Vaccines and Immunization 2001;7(2):119-122
Chickenpox is an acute and highly infectious respiratory disease commonly seen in children.Varicela-zoster often results from the activation of latent virus in chickenpox called varicella-zoster virus(VZV)or called human herpesvirus type 3. Primary infection of VZV may induce typical disease of various severity and most healthy children infected with VZV have mild symptoms and good prognosis.But VZV infection,if occurs in special population such as persons of immune inhibition treatment will induce serious consequence or even death and it is as same serious as in adults.A detailed illustration of molecular biology,epidemiology,laboratory diagnosis,treatment and preventive strategy of the VZV were given.
