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.

Journal of International Oncology 2011;38(2):158-160
Objective To investigate the expression of Skp2 and P27kip1 and their relationship with the clinicopathologic characters in basal cell carcinoma(BCC). To explore their expression between with the types of BCC of skin, especially in morpheaform BCC group. Methods Immunohistochemical SP technique was used to examine the expression of Skp2 and P27kip1 in 50 cases of BCC and 30 cases of normal tissues of skin.The expression level was analyzed combined with clinicopathological features of age, sex and types of tumor.Results Skp2 positive products located in cytoplasm or nucleus. P27kip1 positive products located in nucleus.The high expression of Skp2 and the low expression of P27kip1 were observed in BCC, there was statistical significance between the tumor group and the control group (P < 0. 05 ) . The expression of Skp2 and P27kip1 were correlated with clinical types of BCC ( P < 0. 05 ), while which were not correlated with age and sex ( P >0.05 ). In BCC tissue, Skp2 expression was negatively correlated with P27kip1 ( - 0.624; P < 0.05), there was no correlated with each other in morpheaform BCC group ( P > 0. 05 ). Conclusion The expression of Skp2 and P27kip1 in BCC are significant differences to normal skin tissues, and they are correlated with each other.They may play an important role in carcinogenesis and the development of BCC, and also make targets to treat it. Compared to nodular and superficial BCC group, the expression of Skp2 are higher in morpheaform BCC group, and the expression of P27kip1 is lower. They may play an important role in the types of the BCC and useful factors to predict the types of the tumor, also determine surgical margin for BCC cases.

5.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.
6.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.
