Corneal neovascularization is a significant and sight-threatening complication of many ocular surface disorders, and may cause corneal sear and rejection reaction after corneal grafting. Recent studies have revealed that vascular endothelial growth factor (VEGF) plays an important role in corneal neovascularization, and inhibition of VEGF has become a main strategy for treatment of corneal neovascularization. This article reviews the research progress in inhibition of corneal neovascularization by anti-VEGF therapy.

Objective:To investigate the effect of silver diamine fluoride(SDF)on the bonding strength between dentine and glass ion-omer cement(GIC).Methods:1 2 extracted sound molars were prepared into dintine samples and distributed into sound dentine group and demineralized dentine group.According to the treatment methods,the samples in each group were respectively divided into 3 sub-groups:A(control group),B[coated with 38% Ag(NH3 )F2 ]and C(SDF treatment with additional lighting-curing)(n =20).Then a hand-mixed conventional glass ionomer cement Fuji IX was placed on the dentine surface.After 24 h,micro tensile bond strength test and scanning electron microscope (SEM)analysis were conducted.Results:The bonding strength of demineralized dentine was higher than that of sound dentine(P <0.01 ).SDF with additional lighting-curing treated dentine showed a higer bonding strength value than only SDF treated dentin(P <0.01 ).Conclusion:SDF may improve the bonding between dentine and GIC.

Objective To detect serum CA125 and VEGF in patients of non-Hodgkin lymophoma (NHL) involved in bone marrow and analyse prognostic criteria for NHL. Methods The clinical data of 97 patient were chosen as research objects. They were all first-visit patients. Bone marrow infiltrated with lymphoma cell leukemia of 50 patients were identified by bone marrow aspiration or bone marrow biopsy 46 cases of normal bone marrow were used as controls. The serum CA125 and VEGF were detected by ELISA before treatment. Results Among 97 cases of non-Hodgkin disease, there were 50 cases of bone marrow infiltrated lymphoma cells with a incidence rate of 51.5 %. CA125 and VEGF level in the patients whose bone marrow or lymphoma cell leukemia existed NHL cells was much higher than that of NHL with negative bone marrow infutration (P <0.05). Conclusion CA125 and VEGF can be concluded clinical markers which decide bone marrow or lymphoma cell leukem of the NHL patients whether existed NHL cells or not.

Objective To observe the effects of human retinal pigment epithelium conditioned medium(HRPE-CM) on the biological characteristics of human retinal stem cells(HRSCs). Methods HRSCs were exposed to HRPE-CM and cultivated in three different cultures,including the control,epidermal growth factor(EGF) + basic fibroblast growth factor(bFGF) and HRPE-CM.Cell counting was performed to explore the effects of different culture media on the proliferation of HRSCs,and their properties as neural stem cells were further identified. Results Compared with control group,HRPE-CM significantly promoted the proliferation of HRSCs(P

Objective To investigate the distribution, isolation and culture of the epidermal stem cells from rats. Methods Immnohistochemical methods were used to confirm the location of the epidermal stem cells. The skin of neonatal rats were dissociated into single cells by dispaseⅡ and trypsin solution,the rapidly adherent cells to collgenⅣ were cultured with KSFM,and those no rapidly adherent cells were regarded as control. Immunohistology and flow cytometry were conducted to identify the epidermal stem cells. Results ? 6-integrin and K15 were expressed in the basal layer cells and hair follicle bulge cells, while the CD71 was negative negatively expressed. CD34 were expressed in the hair follicle bulge cells while not in the basal layer cells. The epidermal stem cells isolated by collgenⅣ had higher colony forming efficiency. Immunocytochemical staining showed that ? 6-integrin and K15 were strongly expressed in the cultured epidermal stem cells. Flow cytometry indicated that 84% cultured epidermal stem cells were expressed ? 6-integrin. Conclusion The epidermal stem cells of rats are located at the basal layer of epidermis and the hair follicle bulge.
