To clarify the effects of zinc on the proliferation and apoptosis of cultured human retinal pigment epithelia (RPE) and the expression of caspase-3 in RPE cells. The effect of Zinc on the proliferation of RPE were examined with MTT method. TUNEL method was used to detect the apoptosis of RPE cells. Caspase-3 was detected by immunohistochemistry. A concentration of zinc higher than 0.001 microM could inhibit the proliferation of RPE. And the relationship between concentration of zinc higher than 10 microM and growth prohibition rate of RPE cells was dose-dependent. All concentrations of zinc including 0.001 microM enhanced the expression of caspase-3 of RPE. But only the concentration of zinc higher than 0.01 microM could induce apoptosis of RPE. It is concluded that zinc could enhance the expression of caspase-3 of RPE cells and induce apoptosis of RPE cells. Caution should be taken when using zinc supplements for the treatment of ARMD patients without deficiency of zinc.

Objective To comprehend the action mechanism of simvastatin in pulmonary hypertension(PH)when it induced by high pulmonary blood flow.Methods Abdominal aorta-inferior vena cava shunting was made in rats to establish animal model of PH induced by high pulmonary blood flow,simvastatin with dose of 2 mg/(kg?d)was used to interfere for 11 weeks.And then,pulmonary arterial pressure,apoptosis rate and proliferation rate of pulmonary vascular smooth muscle cell were determined.Results were compared with other groups.Results Simvastatin could cut down the pulmonary arterial pressure well,pulmonary arterial pressures of simvastatin group rats were lower than those of spliting groups obviously(Pa

Objective To explore the role of the preoperative DSA examination and selected embolization in surgical treatment of intracranial huge meningiomas .Methods The clinical materials of 13 patients was collected and analyzed .Preoperative DSA was carried out in all cases ,10 of 13 underwent selected preoperative embolization ,the meningiomas were totally excised by surgery 4 to 7 days after the embolization .Results After the embolization ,DSA showed that the blood fed to the tumors was completely blocked in 8 cases ,and in great part in 2 cases .All tumors were totally removed ,the bleeding during operation was significantly decreased in patients who underwent preoperative embolization compared to the patients without embolization (P<0 .05) .Necrosis in different degree of meningiomas was found in postoperative pathological examination .There were no severe complications occurred during and after operations in all patients .Conclusion Preoperative selective embolization could significantly decrease the bleeding during operations .

Objective To investigate changes of serum cystatin C(Cys C),uric acid,HsCRP, IL-6,TNF-?,and lipids in patients with primary and secondary type Ⅱ b hyperhpidemia.Methods Seventy- five patients with primary and secondary type Ⅱb hyperlipidemia and 75 healthy controls were included in this study.Serum levels of TC,TG,HDL-C,LDL-C,apoAI,apoB,Lp(a),Cys C,UA,HsCRP were measured by immunoturbidimetric assay on AU-640,and IL-6,TNF-? were detected.Results Patients showed higher serum TC,TG,LDL-C,apoB,UA,Cys C and HsCRP than the controls.The levels in patients were(3.70? 0.66)mmol/L,(9.50?0.92)mmol/L,(4.50?0.31)mmol/L,(1.70?0.21)g/L,(1.21?0.17) mg/L,(441.4?114.7)?mol/L,(11.5?3.2)mg/L respectively,while levels in controls were(1.88? 0.66)mmol/L,(4.00?0.66)mmol/L,(2.80?0.33)mmol/L,(0.74?0.23)g/L,(0.71?0.18) mg/L,(343.0?113.9)?mol/L,(1.8?0.7)g/L respectively.Serum Cys C was positively correlated with HsCRP and UA(P

Background The key premise of genetic research and treatment is to select the desired gene vector,ultrasound microbubbles as a new type of gene vector can safe,fast and effectively enhance the gene transfection and expression by reversibility increasing the permeability of cells. Objective This study was to observe the effects of ciliary neurotrophic factor(CNTF)gene mediated by ultrasound microbubbles intraocular transfer on visual function and retinal ganglion cell(BGCs)after optic nerve injury. Methods Fifty-five adult Sprague-Dawley(SD)rats were divided into 6 groups randomly,including normal control group(n=5),sham injury group(n=10),simple injury group(n=10),naked plasmid group(n=10),plasmid+ultrasonic irradiation group(n=10)and ultrasound microbubbles group(n=10).The model of optic nerve injury Was made by forceps clip on the fight optic nerve.and the corresponding intervene was performed in different groups.Flash visual evoked potential(F

AIM:To establish the murine model of oxygen induced retinopathy ( OIR) and to evaluate the inhibition of retinal neovascularization by erythropoietin ( EPO) blockade.
METHODS: Neonates of C57BL/6 mouse ( P7 ) were exposed to 75%±2% oxygen for 5d and return to normal air environment when 12d ( P12 ) to establish oxygen-induced retinal neovascularization model. The neonates were divided into groups, injected with 0. 5μL solution containing 25ng ( group A), 50ng ( group B), 250ng ( group C) of soluble erythropoietin receptor ( EPO-R) or PBS (group D) at P12, P14 and P16 in the right eye. On P17, the litters were sacrificed and their right eyes were enucleated and fixed with 4% paraformaldehyde, made pathological section. The number of breakthrough internal limiting membrane neovascular nuclei was counted with pathological retinal morphology, understanding theproliferative degree of retinal neovascularization.
RESULTS: The pathological sections showed the neovascular cell nuclei which penetrating the inner limiting membrane in intravitreal EPO receptor injection group was reduced statistically than that in PBS injection group, the difference was statistically significant ( P<0.01). And, neovascular nuclei count differences in the
various concentrations of EPO receptor group was statistically significant (P<0. 01). With the EPO receptor concentration increase, neovascular endothelial cells broken through the internal limiting membrane was reduced.
CONCLUSION: Intravitreal injection of soluble EPO receptor can block EPO and improve neovascularization. The new method is expected to become new treatment of ocular neovascular diseases.
