It was investigated that the effect of various inducing mediums,times and temperatures on the number of the zoospores from Diasporangium sp.producing polyunsaturated fatty acid of Eicosapentaenoic acid(EPA) and Arachidonic acid(AA).The results showed that the zoospores were detected in various liquid mediums after 1 day,They were globose and about 23.9 ?m in diameter.And maximum number of spores was obtained 6 days after translocation of mycilium to carrot patches at 25℃.But the number of the zoospores was the most 8 days at the same condition.The highest germination rate of the fungus was obtained in the vegetative agar.

Objective To investigate role of interleukin-1?(IL-1?),interleukin-8(IL-8),tumor necrosis factor-?((TNF-?)) and insulinlike growth factor-1(IGF-1) in meconium aspiration syndrome(MAS) in newborns.Methods The concentrations of(IL-1?),IL-8,TNF-? and IGF-1 in peripheral serum were detected in 32 newborns with MAS and 15 normal newborns by radio-immunity at the first,the third and seventh day after being born.Correlations between IGF-1 and changes of IL-1?,IL-8,TNF-? was analyzed.Results Compared with control group,the concentration of IL-1?,IL-8 and TNF-? increased significantly in newborns with MAS in three days after being born(all P0.05).On the other hand, the concentration of IGF-1 in newborns with MAS was obviously lower than that of normal newborns one week after birth.The concentration of IGF-1 showed negative correlations with that of IL-1?,IL-8 and TNF-?(r=-0.67,-0.61,-0.73 all P

Background Cystoid macular edema(CME) is an important cause of visual impairment of central retinal vein occlusion(CRVO).Spectral-Domain optical coherence tomography(SD-OCT) has increased speed and higher resolution,offering a better chance of understanding the morphological changes and pathogenesis of CME. Objective This study was to survey the morphologic features of macular edema associated with CRVO by SD-OCT. Methods Clinical data of the patients with CRVO diagnosed in Department of Ophthalmology,Peking Union Medical College Hospital from March 2008 to August 2009 were retrospectively analyzed.SD-OCT features of macular edema induced by CRVO were analyzed and recorded.Results The average macular foveal thickness was(527.5±218.2) μm in macular edemas eyes.Main morphological changes included 55 cases(84.6%) of CME,15 cases of(23.1%) serous macular detachment(SMD),and 10 cases(15.4%) of simple macular edema,and these findings occurred at the same time in some eyes.Cystoid spaces in the parafoveal region were seen in the inner nuclear layer,outer plexiform layer and outer nuclear layer,and discontinuous or weak inner segment/outer segment(IS/OS) line was often seen in CME.The incidence of CME associated with incomplete posterior vitreous detachment(PVD) was 14.5%,and that of neural epithelial edema associated with incomplete PVD was 10.0%,showing an insignificant difference between them(χ2=0.000,P=1.000).The average area of SMD was 1838.4μm ×1428.1μm×190.1μm,and the incidence of partial PVD was higher(χ2=4.266,P=0.039).Conclusion SD-OCT can reveal the micro-morphological change of macular zone in macular edema eye.SD-OCT enabled visualization of its spatial extent in each retinal layer and the condition of IS/OS layer.Serous macular edema is related with partial PVD.

?AlM: To investigate theprotective effect of melatonin against hydrogen peroxide ( H2 O2 )-induced oxidative damage to human lens epithelial cells.
?METHODS: Sub-culture human lens epithelial cells preprocessed with different concentrations of melatonin for 12h and then 100 μmol/L H2 O2 for 24h. The impact of melatonin on H2 O2-induced lens epithelial cell viability was detected by MTT assay, rate of apoptosis was detected by flow cytometry instrument and activity of apoptosis-related factors, Caspase-3 and Caspase-9, were detected by colorimetric method.
?RESULTS: MTT assay showed that melatonin had no effect on the activity of lens epithelial cells, and the drug can inhibit the decrease of H2 O2-induced cell activity, as well as flow cytometry showed that melatonin can inhibit H2 O2-induced apoptosis. ln addition, melatonin can also reduce H2 O2-induced Caspase-3 and Caspase-9 activity in lens epithelial cells, and their activity decreased with effect of melatonin along with extending time.
?CONCLUSlON: Melatonin can obviously inhibit H2 O2 -induced apoptosis of human lens epithelial cells, which provide reliable experimental basis for drug on treatment of cataract.

ObjectiveTo investigate the positive rates of serum antibodies to TORCH in women who want to have a baby or in the early period of pregnancy.MethodsSerum TORCH-IgM or TORCH-IgG in 500 women were measured with IgM capture ELISA.ResultsThe positive rates of serum TORCH-IgM were 0 in TOX samples,0.2% in RV samples,0.2% in CMV samples,1.4% in COXB samples and 0 in HSV samples;while the positive rates of serum TORCH-IgG were 0.2% in TOX samples,51.6% in RV samples.ConclusionSerum TORCH-IgM and TORCH-IgG screening in women who want to be a mother or in the early period of pregnancy should be strengthened.
