Background The primary pathological basis of diabetic retinopathy (DR) is new blood formation due to anoxia and inflammation,which results in breakdown of blood-retinal barrier (BRB).Vascular endothelial growth factor (VEGF) is a key factor promoting neovascularization.Researches determined that lycium barbarum polysaccharides (LBP) can protect cells against oxidative damage.However,the study of LBP in ophthalmology is lack.Objective This study was to investigate the effects of LBP on the dynamic pathological change of retinal vessels and expression of VEGF in retina of diabetic rats.Methods One hundred and seventeen SPF male SD rats were randomly divided into the normal control group,the diabetic mellitus (DM) group and the LBP group according to random number table.Type 1 DM models were induced by intraperitoneal injection of streptozotocin (STZ,55 mg/kg) in the rats of the DM group and the LBP group,and then 250 mg/kg LBP was intragastically administered in the rats of the LBP group.The morphological change of retinal vessels was dynamically observed by retinal stretched preparation with Evans blue (EB) in 4,10 and 16 weeks after modeling.E B (45 mg/kg) was slowly injection via jugular vein,and 1％ polyoxymethylene was infused into the left ventricule.The eyeballs were extracted and retina were isolated.EB content in the retinas (mg/g) was calculated using retinal stretched preparation method at the time points mentioned above.Expressions of VEGF protein and mRNA in the retinas were detected by immunohistochemistry and real-time quantitative PCR at various time points,respectively.Results Retinal stretched preparation with EB exhibited that the abnormal degree in the shape,diameter of vessels and leakage of the retinal blood vessels were significantly slighter in the LBP group than those of the DM group in 4,10,16 weeks after modeling.At 4,10,16 weeks,EB content in the retinas was (12.17±1.55),(16.46±1.60) and (19.55±1.49) mg/g,which was significantly lower than (15.76± 1.90),(21.61 ±2.05) and (26.30±2.28) mg/g of the DM group (P＜0.05).Immunochemistry showed that the expression of VEGF protein primarily located at retinal ganglion cells (RGCs) layer.The staining intensity for VEGF protein was weaker in the LBP group than that of the DM group.The expression levels of VEGF protein (A value) in the LBP group were 0.234±0.011,0.331±0.023 and 0.536±0.031at various time points,with significant decline in comparison with 0.281±0.018,0.533±0.055 and 0.765±0.075 of the DM group (all at P＜0.05).Real-time quantitative PCR revealed that the expression levels of VEGF mRNA were 0.157±0.013,0.505 ±0.114 and 1.577±0.074 in the LBP group at various time points,which were significantly lower than 0.235±0.209,1.043±0.084 and 2.446±0.061 of the DM group (all at P＜0.05).Conclusions LBP can alleviate the DM-induced retinal vasculopathy,lessen the leakage of vessels well,and further protect the BRB.

T was genotyped by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)in all the patients.Results The occurrence of CR in this population was 23.3%(70/300).There was CYP3A4 894C/T polymorphism in the study population.The frequencies of the three kinds of genotypes(CC,CT,TT)in CR group and non-CR(NCR)group were 45.7%,50.0%,4.3% and 63.5%,31.7%,4.8%,respectively.The frequency of TT genotype was significantly higher in NCR group than that in CR group(OR=2.06,95% CI:1.201-3.547,P=0.020).C allele carriers were more likely to develop clopidogrel resistance compared with that of T allele carriers(OR=1.59,95% CI:1.037-2.442,P=0.023).Conclusion CYP3A4 gene 894C/T polymorphism is associated with the risk of CR,and C allele carriers may be a possible genetic susceptibility factor for patients with CR.

Objective To explore the perioperative antithrombotic strategy in percutaneous coronary intervention(PCI)for the patients with coronary heart disease(CHD)who were treated with long-term warfarin anticoagulation,and to evaluate the safety of the strategy and short-term efficacy.Methods The clinical data of 76 patients were analyzed,who underwent coronary stenting while treated with long-term warfarin anticoagulation.All of them had unstable angina.The reasons of requiring warfarin anticoagulation were cardiac valve replacement [51(67.1%)],pulmonary embolism within half a year [6(7.9%)],and sustained atrial fibrillation at high risk of stroke [19(25.0%)].Warfarin was withdrawn and low molecular weight heparin(LMWH)was administered as alternative anti-thrombus drugs before PCI.PCI was performed when international normalized ratio(INR)went less than or equal to 1.3.LMWH was administered combined with low dose aspirin(100mg/d)and clopidogrel(75mg/d)post PCI,while warfarin was resumed too.When INR arrived at 1.8,LMWH was withdrawn.Warfarin was administered in a dose adjusted to achieve the target INR of 1.8 to 2.3.Clopidogrel was withdrawn 1 month later.Aspirin(75-100mg/d)was continued,and then warfarin was resumed to the dose before PCI.The data of the incidence of ischemic events,major adverse cardiac events(MACE),subacute instent thrombus(SAT),and hemorrhage events during hospital period were analyzed.Results The incidence of hemorrhage events was 5.3%(4/76),one of them was secondary hemorrhage events.The rate of MACE was 1.3%(1/76).No main hemorrhage events and SAT occurred during hospitalization related to regulating antithrombotic strategy.Conclusions As alternatives of warfarin,LMWH is taken before PCI,and then the low dose of aspirin,clopidogrel,LMWH and warfarin are admitted in a short period after PCI,the dosage of warfarin should be accurately adjusted according INR post PCI,and then the LMWH is taken out of service timely,such a strategy is safe and efficient in peri-percutaneous coronary intervention for the patients with CHD who were treated with maintaining warfarin anticoagulation.
