ABSTRACT

Retinal vein occlusion(RVO), the second most prevalent retinal vascular disease, has complex pathophysiological mechanism. Except for mechanical pressure on blood vessel, inflammation and endothelin have been confirmed to be involved in the pathogenesis of RVO. However, its specific mechanism remains unclear. Hypertension, diabetes and dyslipidemia have been previously shown to be the most common risk factors in elder population, while recent studies found that coagulation and hemorheological abnormalities are more common in people under 50 years old. Ocular risk factors including glaucoma, high corrected intraocular pressure and retinal vessels abnormality, have gained more and more attention. These factors probably exert a synergistic effect when present simultaneously in the same patient. Therefore, early identification and intervention of those factors could lower the incidence of RVO. This article aims to review recent research and summarize existing mechanism and theories, giving some new research ideas for potential therapy targets and providing references for identification and management of risk factors.

ABSTRACT

Objective To develop transgenic mice harboring the fusion gene of mutant amyloid precursor protein and two types of fluorescent protein for the future study on Alzheimer's disease.Methods The fusion gene CFP-54 bp-YFP-C99 was introduced into mice by mieroinjection.The presence of CFP-54 bp-YFP-C99 was confirmed by PCR in the founders.Results CFP-54 bp-YFP-C99 gene was injected into pronucleus of 2202 zygotes and 1806 injected eggs were implanted into 56 foster mothers, 13 of which were pregnant.There were 13 foster mothers who borne 52 offspring and 32 of them survived.Recipient mouse pregnancy rate was 23.2% (13/56) and the integration rate was 3.9% (2/52).Conclusion CFP-54 bp-YFP-C99 transgenic mice is obtained, but the transgenic efficiency is low.
