OBJECTIVE:To observe the effects of Tanshinone ⅡA sulfonic acid sodium injection on blood supply and blood rheology of patients with central retinal vein occlusion )CRVO). METHODS:92 CRVO patients were selected and randomly divided into control group and trial group with 46 cases in each group. Control group was given routine treatment of laser photocoagulation;trial group was additionally given Tanshinone ⅡA sulfonic acid sodium injection 80 mg added into 0.9% Sodium chloride injection 150 ml,ivgtt,qd. A treatment course of 2 groups lasted for 7 days,and both received 4 courses of treatment. The hemodynamics and hemorheology of central retinal artery (CRA) were recorded in 2 groups before and after treatment. The fluorescence angiogra-phy (FFA) and optical coherence tomography (OCT) of 2 groups were also observed. RESULTS:Before treatment,there was no statistically significant difference in Vmax,Vmin and RI of CRA between 2 groups (P>0.05);after treatment,Vmax,Vmin and RI of CRA in 2 groups were improved significantly,the trial group was better than control group,with statistical significance(P<0.05). After treatment,whole blood high shear viscosity,whole blood low shear viscosity,plasma specific viscosity and fibrinogen of trial group were significantly lower than those of control group,and FFA and OCT of trial group were better than those of control group, with statistical significance(P<0.05). CONCLUSIONS:TanshinoneⅡA sulfonic acid sodium injection can obviously improve hemo-dynamics and hemorheology of CRVO and blood supply and vision of lateral eye.

Objective To evaluate the effect of refractive correction on the dynamic variation of diopter in children with hyperopia ametropic amblyopia. Methods Optometry with 1 % atropine oculentum was used to examine 105 patients(210 eyes) with ametropic amblyopia aged 3～6 years old. The diopter of all the cases was compound hyperopic astigmatism. The prescriptions of spectacles were made according to that the diopter of retinoscopy subtracted different degree hyperopia. Thus,all the patients were divided into group 1(subtract 20% off the diopter of retinoscopy,30 cases),group 2(subtract 25% off the diopter of retinoscopy,40 cases),group 3(subtract 30% off the diopter of retinoscopy,35 cases). During three years' treating periods, their dynamic variation of hyperopia diopter were observed time yearly. Results The hyperopia diopter of each group reduced year after year. But the average reduction of hyperopia diopter of group was significantly lower than that of other two groups(P0.05).Conclusion Refractive corrections of different degree have effect on emmetropization of children with hyperopia ametropic amblyopia. Moderate undercorrection is useful on emmetropization of children with hyperopic ametropic amblyopia.

Objective: To obtain the bFGF mimic peptide binding to FGFR via phage display, and to provide the base for developing peptide agonist of bFGF. Methods: Using Balb/c 3T3 cells as the target cells and COS-7 cells as the subtractive panning, the phage display heptapeptide library was biopanned for 4 rounds to obtain the single phage clones. The affinity and the specificity of the clones were assessed by ELISA. DNA sequencing was applied to further analyze the positive clones. Results: Twelve positive clones were selected from the enriched phages. A group of hydrophobic peptides containing a conserved motif, PR, was identified. Conclusion: Two bFGF mimic heptapeptides binding to FGFR were selected, which may be used as the candidates for bFGF agonist.

Objective To establish a calcification mode in vitro of human vascular smooth muscle cells (HVSMCs) induced by β-GP. Methods Primary HVSMCs were obtained from human embryo by plant method and confirmed by stain with α-sm-actin antibody. The cells after 4-6 passages were divided into two groups.The control group was incubated with normal DMEM medium while the calcification group was incubated with the medium containing 10 mmol/L β-glycerophosphate for 10 days.Calcification was confirmed by alizarin red S stain and alkaline phosphatase(ALP) assays. Results The primary cells observed by S-P stain were positive and the cells after being stained were pale yellow. After being induced with β-GP, the cells of calcification group began concentric growth and formed vesicles. Alizarin red S staining showed that the reaction of calcifying nodules was red,ALP activity was higher than that of controls at various time points(4 d,6 d,8 d and 10 d,P＜0.01 ).Conclusion The HVSMCs could be induced into calcification in vitro by β-GP, and this model contribates to further studies of vascular diseases.

Objective To observe effects of ganoderma lucidum triterpenoids(GLT) on learning and memory function and anti-oxidative ability of aging model mice induced by D-galactose. Methods Senile model mice were established by D-galactose hypodermic injection for 8 weeks.GLT had been administered to two therapy groups.All the mice of different groups were tested with Morris water maze.Then the mice were killed and biochemically assayed of total anti-oxidative capacity(T-AOC),superoxide dismutase(SOD) and malondialdehyde(MDA) in the brain. Results The model mice showed worse ability in learning and memory in comparison with control mice.The T-AOC activity and SOD activity in the brain decreased and the MDA content increased in model rats in comparison with control.GLT significantly improved the changes mentioned above. Conclusion GLT improved the learning and memory dysfunction in aging model mice by modulation of the anti-oxidative ability.
