Background Retinopathy of prematurity is mainly due to retinal neovascularization.Objective This laboratory work was to evaluate the efficacy of different dosage of avastin for inhibiting retinal neovascularization.Methods Ninety 7-day-old clean C57BL/J6 mice were randomized into six groups as follows:air control group,hyperxia control group,hyperxia BSS group and avastin groups.C57BL/J6 mice in air control group were raised in regular air environments.The fifty mice were fed under the environment with 75％ ±2％ oxygen for 5 days to establish the retinal neovascularization models.The 1.25,2.50 and 5.00 g/L avastin (0.5 μl) were injected inteavtreally in forty-five mice models as low,moderate and high dosage avastin groups respectively,and 0.5 μl BSS was used at the same way in fifteen models as hyperxia BSS group.The mice were sacrificed in the 17-day-old age using excessive anesthesia method and the retina sections were prepared for the calculation of the numbers of vascular endothelial cell nuclei broken retinal inner membrane after hemotoxylin and eosin staining.The expression of CD34 in the retina was detected by immunochemistry.The morphology and distribution of retinal neovascular vessel in various groups were observed using retinal flat.The use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The numbers of cell nuclei broken the inner limiting membrane was significant increased in the hyperxia group compared with the air control group( P＜0.01 ),and those in difference doses of avastin were considerably reduced in comparison with hyperxia BSS group (P＜0.01) and hyperxia group (P＜0.01 ).The decrease of numbers of cell nuclei broken the inner limiting membrane was obvious in low dose of high dose of avastin compared with low dose of avastin (P＜0.05 ).CD34 was positively expressed in retina internal membrane of hyperxia group.Retinal flat revealed the regular distribution and normal structure of retinal vessels in air control group and avastin groups.However,retinal and vitreous cavity neovascularization,leakage and enlarged non-perfusion regions in the perimeter of the retina were seen in hyperxia group and hyperxia BSS group. Conclusions Intravitreal injection of avastin can arrest retinal angiogenesis in oxygen-induced retinal neovascularization models in a dose-dependent manner.

Objective To investigate the effects of exercise training(ET)on the expression of glucogen synthase kinase 3 bate(GSK 3?)in the adipose tissues of insulin resistant(IR)rats on a high fat diet(HFD). Methods Thirty male Wistar rats were randomly divided into a control group(n=10)and a model group(M group,n=20).Insulin resistance was established by feeding a HFD to the M group for 4 w,while rats in the control group were fed a normal diet.The IR rats were then randomly divided into two subgroups:an IR group and an ET group.All rats in the IR and ET groups were fed a HFD,but ET was administrated to the ET group for 6w.The expres- sion of GSK 3?protein in the rats'epididymis adipose tissue was detected using Western blotting,and body weight (BW),the concentrations of serum triglyceride and cholesterol(TG and TC),fasting plasma glucose(FPG)and serum insulin(FINS),as well as insulin sensitivity index(ISI)were regularly detected.Results Compared with the con- trol group,BW and the concentrations of serum TG and TC,FPG and FINS in the model group were significantly in- creased(P＜0.05),while ISI was decreased(P＜0.01).Compared with the control group,there was no difference in GSK 3 protein expression in the ET group,but the expression of GSK 3?protein in the ET group was obviously de- creased in comparison with that in the IR group(P＜0.05).Conclusion ET can ameliorate IR by decreasing GSK 3?protein expression in adipose tissues and enhancing the ingestion of glucose and the synthesis of glycogen.
