Chinese Journal of Experimental Ophthalmology 2014;32(1):88-93
Retinal pgment epithelial (RPE) cells plays a key role in maintaining the normal physiological function and structure of retina and choroids.However,RPE cells are vulnerably damaged by many detrimental factors,such as anoxia,physical and chemical elements,pharmic,immunizing factors and oxidant stress,etc.The damage of RPE cells lead to multiple eye diseases,and therefore cause severe abnormality of visual function.To understand the causative factors of RPE cell-related eye diseases is very important for the prevention and treatment of these diseases.Recently,many studies about damage factors and treatments for RPE cells have received more attention.This article reviews the advances in RPE cell-related eye diseases.

Objective To evaluate the clinical significance of the changes of plasma B-type natriuretic paprid and NT-pro BNP levels in patients with chronic heart failure(CHF).Methods 120 consecutive patients hospitalized for CHF were retrospectively studied.NT-pro BNP and LVEDD,LVESD,LVEF were measured and compared in 120 patients and 50 normal control subjects before medical treatment and on discharge.Results The plasma NT-pro BNP levels in patients with CHF were significantly higher than controls( P <0.05).The plasma NT-pro BNP levels in patients with cardiac function NYHA Ⅰ were significantly higher than controls( P < 0.05).As the cardiac function deteriorated from NYNA Ⅰ to NYNA Ⅳ,the NT-pro BNP levels increased consecutively with significant differences from each other ( P < 0.05).The plasma NT-pro BNP levels was low when CHF was cured ( P < 0.05 ).Conclusion Determination of plasma NT-pro BNP levels in patients with CHF were helpful to study the severity and prognosis of disease.

BACKGROUND: The central position of dendritic cells (DCs) has aroused increasing attention due to strong antigen presentation capability in anti-tumor. However, how to obtain enough functional DCs and reports regarding immunomodulator with low toxicity are few. OBJECTIVE: To investigate the effect of mycobacterium phlei F.U.36 (Utilins) on the proliferation and maturity of DCs derived from human umbilical cord blood in vitro.METHODS: The mononuclear cells were isolated from human umbilical cord blood using Ficoll-Hypaque method and cultured with Utilins, cytokine (human recombinant granulocyte/macrophage colonystimulating factor + recombinant human tumor necrosisfactor-α + recombinant human interleukin-4), or combination cytokine + Utilins, respectively. In addition, cells cultured with RPMI-1640 served as controls. Morphological features and growth of DCs were observed by an inverted microscope. Thephenotype changes of DCs, such CD1a and HLA-DR, were detected by flow cytometry at 9 days after culture. Moreover, DCs were stained by Wright-Giemsa and observed under oil lens. RESULTS AND CONCLUSION: Typical DCs with high expressions of CD1a and HLA-DR were obviously detected in all experimental groups except the control group. The positive rates of CD1a and HLA-DR in the Utilins group were higher than those in the control group, but lower than the cytokine group (P < 0.05). The HLA-DR positive rate of the combination group was higher than that of the cytokine group (P < 0.05). The results revealed that, Utilins can not only promote the proliferation of DCs derived from human umbilical cord blood in vitro but also cooperate with cytokines to induce the maturity of DCs.

Objective Through pathological and histological examination on retina to research the dosage relevance of trace PFD with toxicity in rabbit retina,and provide experimental reference basis for clinical practice.Methods Fourty eight eyes from 24 experimental rabbits were randomly divided into experimental group(36 eyes) and control group(12 eyes).The experimental one was divided into 3 groups,12 eyes in each group.The surface of rabbit retina was directly injected with 30,50,and 100 ?L liquids of PFD and BSS.The conditions of rabbit retina were observed under ophthalmoscope every day after the liquid injection.The sections of retina tissue were observed under transmission electron microscope in each experimental and control groups at the 4th,7th,14th and 21th day after injection.Results All samples were normal by ophthalmoscope examination while no pathological change of retina was found at various time points .At the 4th day,none substantial damage had been made in any dosage groups by transmission electron microscope examination except for 100 ?L group.Only one retina of 100 ?L group showed that the space around cell nucleus broadened appreciably,slightly atactic nucleus and slightly compact cytoplasm.It showed some early changes.From the 7th day,similar pathological changes were found: damage on outer segments of light receptor and outer plexiform layer,properties changes of light receptor,forming of vesicles of inner nuclear cells,damage of ganglion cell,dying of inside retina,actions of gulping cells in retina,swallow of film plates by pigment epithelial cell of retina,and dropping of top fine hair. But the retina of control group had no pathological changes.Conclusion Trace PFD exists in eyes.There is no relevance between poisonous development of retina and remaining dosage of PFD.However,large remaining of PFD can lead to retina toxicity early.
