AIM:To investigate retinal vascular endothelial growth factor(VEGF)level and retinal cells apoptosis in the early stage of diabetic NOD mouse retina.METHODS:Animals were divided into the control group(non-diabetes mice)(2,4,6,8,12 weeks group,n=30)and diabetes group(2,4,6,8,12 weeks group,n=30).EUSA(Enzyme-Linked Immunosorbent Assay)was performed to detect VEGF level in both serum and retina.Transmission electron microscope method was used to examine retinal cell apoptosis.RESULTS:Compared with the control group,VEGF levels in serum and retina were increased significantly in the NOD group(12 weeks:4.9±0.4μg/g versus 0.19±0.1μg/g in serum sample,P ＜ 0.01;165.0±9.0μg/g versus 18.0±4.0μg/g in retinal sample,P＜0.01).There exists a positive correlation between serum VEGF and retinal VEGF levels in the early diabetic NOD mice(γ=0.9902,P=0.001).The number of the cells apoptosis in the ganglion significantly in the NOD group(P＜0.01).CONCLUSION:The high VEGF expression may be contributed to increase retinal cells apoptosis.Many factors associated with retinal VEGF expression might involve in the early diabetes stage.

Diabetes is a complex and heterogeneous disorder presently affecting more than 100 million people worldwide and causing serious socio-economic problems. Spontaneous rodent models of diabetes mellitus have proved invaluable in understanding the pathogenesis, complications, and genetic or environmental influences that increase the risks of diabetes. We have reviewed here in the development and characterization of spontaneous rodent models that displayed most features commonly associated with diabetic retinopathy.

Objective To investigate the effects of deguelin on the proliferation inhibition and apoptosis induction in RPMI-8226 cells in vitro,as well as the regulation of steroid receptor coactivator-3(SRC-3)to explore the relationship between them.Methods The effect of deguelin on the growth of RPMI-8226 cells was studied by MTT assay.Apoptosis was detected through Hoechst 33258 staining and Annexin-V FITC/PI double-labeled cytometry.RT-PCR Technology was applied to assessment of the mRNA expression of SRC-3,whereas,SRC-3 protein expression and localization were determined by using immunohistochemistry method.Results Deguelin presented striking proliferation inhibition potency on RPMI-8226 cells in vitro and apoptosis induction activity in a time-and dose-dependent manner.The IC50 value for 24 h was(54.55?0.40)nmol/L,(17.04?0.73)% RPMI-8226 cells went apoptotic when treated with 25 nmol/L deguelin for 24 h,with the dose of deguelin increasing to 100 nmol/L,(63.57?1.36)% cells were apoptotic.Over-expression of SRC-3 was found in RPMI-8226 cells,whereas the mRNA and protein expression levels of SRC-3 were significantly downregulated in RPMI-8226 cells induced by deguelin in a dose-dependent manner.The disposition of SRC-3 was situated mainly at the nuclear,occasionally in the cytoplasm.Conclusion Deguelin exhibited potent proliferation inhibition to the human myeloma cell line RPMI-8226 cells,furthermore,deguelin might induce RPMI-8226 cells apoptosis in a dose-dependent manner,which might correspond to the regulation of the expression of SRC-3.

Aldose reductase ( AR ) belonging to nicotinamide-adenine dinucleotide phosphate ( NADPH ) -dependent aldehyde-keto reductase superfamily, is the key rate-limiting enzyme in the polyol pathway which plays an important role in the body’s high-sugar metabolism. AR is widely present in the kidneys, blood vessels, lens, retina, heart, skeletal muscle and other tissues and organs, converts glucose to sorbitol which easy permeability of cell membranes, cause cell swelling, degeneration, necrosis, and have a close relationship with the development of chronic complications of diabetes mellitus. Diabetic retinopathy ( DR ) is a multifactorial disease, the exact cause is currently unknown, but polyol pathway has been demonstrated to play an important role in the pathogenesis of DR. Clinical risk factors such as blood sugar control, blood pressure and other treatments for DR only play a part effect of remission or invalid, if we can find out DR genes associated with the disease, this will contribute to a better understanding of the pathological mechanisms and contribute to the development of new treatments and drugs. The current research progress of AR, AR gene polymorphism, Aldose reductase inhibitors to DR was reviewed in this article.

AIM: To evaluate the effect of intravitreal bevacizumab (IVB) injection 1 week before pars plana vitrectomy (PPV) in proliferative diabetic retinopathy (PDR) patients. METHODS: A retrospective research was done on 46 PDR patients who were divided into PPV group (n=28) and IVB group (n=18, PPV with preoperative IVB). Bevacizumab was injected 1 week before PPV. Main outcome measures were visual acuity, incidence of iatrogenic retinal breaks, intraoperative and postoperative bleeding. RESULTS: At 1 month after surgery, visual acuity in PPV (82.1%) and IVB group (88.9%) improved significantly (P<0.01) and the difference between the two groups was not significant. Iatrogenic retinal breaks were reported in 18 cases (64.3%) in PPV group and 4 cases (22.2%) in IVB group (P<0.05). Intraoperative bleeding was encountered in all cases in PPV group and 7 cases (39%) in IVB group (P<0.01). Postoperative bleeding was reported in 9 cases (32.1%) in PPV group and none in IVB group (P<0.01). CONCLUSION: IVB injection before PPV is helpful in reducing iatrogenic retinal breaks, intraoperative and postoperative bleeding in PDR patients.

?ln recent years, the number of patients with diabetes increase rapidly. Diabetic retinopathy ( DR ) , one of the complications of diabetes, is also the important aspect of current and future prevention of blindness in our country. Now, more and more scholar have noticed the important role of immune inflammation in the pathogenesis of diabetic retinopathy. ln this article, we reviewed the role of interleukin-6 ( lL-6 ) in diabetic retinopathy.

Medical emergency response is a part of emergency response to nuclear accident,and the equipment and technology play an important role in the process.So it's important and necessary to research the equipment and technology requirements of medical emergency response to nuclear and radiation accident.The aim of the paper is to screen and list some basic equipments and technology in medical emergency response to nuclear and radiation accident,such as individual internal and external exposure dose monitor,radiation detection appliance,decontamination and radiation protection equipment as well as first-aid instrument.
