Background It has been proved that as an important adhesion protein of extracellular matrix,osteopontion (OPN) can affect tumor neovascularization.Some new researches showed that anti-OPN antibody plays a role in regulating the neovascular vessel formation.Choroidal neovascularization (CNV) has the same structure with tumor neovascularization,but whether anti-OPN antibody restricts new vessel formation is unclear.Objective This study was to investigate the inhibitory effect of anti-OPN antibody on CNV.Methods Laser-induced CNV models were created in 40 eyes of 40 male SPF C57BL/6J mice by Argon laser photocoagulation of retinas,with the wavelength 514 nm.Thirty-six successful models were randomly divided into anti-OPN antibody group,mouse-IgG group and PBS group by the randomized number table.On the second day after photocoagulation,anti-OPN antibody of 400 μg was intraperitoneally injected in the anti-OPN antibody group,and the equivalent amount of mouse IgG and PBS were used in the same way in the mouse IgG group and PBS group.The CNV was evaluated by fundus fluorescein angiography (FFA) on the seventh days after photocoagulation.The mice were immediately sacrificed and the eyeballs were enucleated on the fourteenth day after photocoagulation,and 4 eyeballs in each group were used to observe the areas of CNV on the retinal pigmental epithelium-choroid-sclera fiat mounts,and the other 8 eyeballs of each groups were used to analyze the expression levels of OPN mRNA and vascular endothelial growth factor(VEGF) mRNA using quantitative fluorescence-PCR (QF-PCR).Results FFA showed fluorescein leakage areas around laser spots 7 days after photocoagulation,indicating that CNV appeared.The CNV areas were ([16.98±0.70] × 103) μm2,([27.13 ± 0.81] × 103) μm2 and ([35.39±2.14] ×103) μm2 respectively in the anti-OPN antibody group,mouse IgG group and PBS group,with a significant difference among the 3 groups (F =533.76,P =0.00),and the CNV area was significantly smaller in the anti-OPN antibody group compared with those of the mouse IgG group and PBS group (q =-3.95,-4.40,both at P＜0.05).No significant difference was found in the OPN mRNA expression between the antiOPN antibody group and mouse IgG group (t =-5.26,P =0.66).However,the expression of VEGF mRNA in choroidal tissue was significantly declined in the anti-OPN antibody group than that in the mouse IgG group (t =-6.74,P＜0.01).Conclusions Anti-OPN antibody suppresses the formation of CNV in laser-induced mouse model by down-regulating VEGF.

?AIM: To study the changes of choroidal thickness and hemodynamic parameters in patients with diabetic retinopathy and their influencing factors.?METHODS: From January 2013 to January 2015, 100 patients (100 eyes) with type 2 diabetes were divided into 3 groups:34 patients without diabetic retinopathy ( NDR) , 36 patients with non proliferative diabetic retinopathy ( NPDR) group, and 30 patients with proliferative diabetic retinopathy (PDR). According to the results of OCT, the patients with diabetic retinopathy were divided into 2 groups: diabetic macular edema ( DME ) group ( 28 cases) , and 38 cases without diabetic macular edema. During the same period in our hospital 35 subjects for physical examination were selected as the control group. The hemodynamic parameters of the posterior ciliary artery in different groups of patients at different distance from the center of the macular were compared, analyzing influencing factors.?RESULTS:With the aggravation of diabetic retinopathy, the choroidal thickness in different distance from the center of the macular decreased. The choroidal thickness of NPDR and PDR group were thinner than that of the control group (P<0. 05). The choroidal thickness of NDR group was not different from the control group (P>0. 05). There was no significant difference in the choroidal thickness between the DME patients and non DME patients (P>0. 05). Pearson correlation analysis showed that there was no significant correlation between choroidal thickness of patients with diabetic retinopathy and diabetic duration, fasting blood glucose, HbA1c, eye axis length, systolic blood pressure and diastolic blood pressure (P>0. 05), but there was a correlation with BCVA (logMAR) (P<0. 01). EDV and PSV in NDR group and NPDR group were significantly lower than those in control group, RI was higher than that in control group. PSV and EDV in PDR group were significantly lower than those in other three groups, RI was higher than the other three groups, and the difference was statistically significant ( P<0. 05).?CONCLUSION:With the severity of retinopathy in type 2 diabetic patients, the choroidal thickness decreased, and the thickness of the choroid is beneficial in the comprehensive analysis of 2 diabetic retinopathy.

OBJECTIVETo observe the effect of Oxymatrine on left cardiac function and ventricular remodeling in rabbits after acute myocardial infarction.

METHODSLigation of the left anterior descending artery was adopted to establish acute myocardial infarction model, forty eight rabbits were randomized into the sham operation group, model group and Oxymatrine group. Eight models were successfully established in each group. the sham operation group and model group were given conventional feed. Oxymatrine were gavage administration 0.5 ml/100 g, once a day, lasted for 4 weeks. Respectively in postoperative week, and three weeks, to observe the Oxymatrine on cardiac output (CO), left ventricular end systolic pressure (LVESP), left ventricular end-diastolic pressure (LVEDP), left indoor pressure change rate peak (dp/dtmax)), and left ventricular cavity internal diameter (D), ventricular weight index (VWI), ventricular weight (VW).

RESULTSLeft ventricular anterior wall was from red to deep purple, electrocardiogram showed II guide ST-segment camber up ≥ 0.25 mv. Postoperative week in Oxymatrine group compared with model group, LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P < 0.01); After three weeks in Oxymatrine group compared with model group, VW, VWI decreased (P < 0.05), D significantly reduced (P < 0.01); LVESP increased significantly (P < 0.01), LVEDP decreased obviously (P <0.01); dp/dt(max), CO increased (P < 0.05).

CONCLUSIONAfter acute myocardial infarction in rabbit Oxymatrine can improve the left ventricular reconstruction parameters, increase cardiac output, and improve cardiac function.
