Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.

Objective To determine the content of gallic acid and evaluate the quality of Galla chinensis of different habitats in Guizhou Province. Methods HPLC method was used to determine the content of Gallic acid on Alltima C18 column (4.6 mm?250 mm, 5 ?m) with the mobile phase of methanol-water-phosphoric acid (15∶85∶0.085). The flow rate was 1.0 mL/min and the detective wave length was 270 nm. Results The contents of Gallic acid in Galla chinensis of 10 different habitats in Guizhou Province were 51.43%～ 60.25%. Conclusion The quality of Galla Chinensis in different habitats in Guizhou Province are up to the Chinese Pharmacopoeia, and the individual varibility is significant.

AIM:To compare the clinical efficacy of three combined surgical treatments for cataract induced by silicone oil -filled eye.
METHODS: The data of 75 eyes of 75 patients with cataract induced by silicone oil-filled eye were reviewed. Those patients were divided into group A, B, C. The patients in group A were treated by phacoemulsification combined with silicone oil removal through pupil and IOL implantation, the patients in group B were treated by phacoemulsification combined with silicone oil removal through 23G vitrectomy system and IOL implantation, the patients in group C were treated by phacoemulsification combined with silicone oil removal through 20G vitrectomy system and IOL implantation. The operation time, intraocular pressure, best corrected visual acuity ( BCVA ) , discomfort days and complications before and after the surgery were compared.
RESULTS: The differences of the intraocular pressure were not statistically significant between the three groups after the surgery. The BCVA of the three groups were all improved, but the differences were not statistically significant between three groups. The differences in postoperative complications showed no statistically significant. Otherwise, group A and B cost less operation time. The discomfort days of group A were less than other groups.
CONCLUSION: Three different surgical methods were safe and effective, appropriate surgical approach could be chosen according to the patients' clinical manifestations. For patients with cataract induced by silicone oil-filled eye whose retina recovered well, phacoemulsification combined with silicone oil removal through pupil and IOL implantation is a time-saving, safe and effective method.

Background The early diagnosis and treatment is vital for the age-related macular degeneration (AMD).Previous examining methods were fundus fluorescein angiography(FFA)and optical coherence tomography (OCT).However,a new diagnostic technique,fundus autofluorescence(FAF),is applying in ophthalmology.objective This study was to observe the FAF characteristics of atrophic AMD. Methods Thirty-nine eyes of 28 patients with atrophic AMD were diagnosed and collected in our hospital and classified based on the criteria of Chen Song.FAF was performed by a confocal scanning laser ophthalmoscope(Heidelberg Retina Angiograph 2,HRA2).Characteristics of FAF images were compared with FFA images or color fundus photographs.Written informed consent was obtained from each patient prior to the examination. Results Areas with abnormal increased or decreased FAF signals were consisted or unconsisted with funduscopically visible alterations.Seven manifestations of FAF were found in the eyes with preatrophic stage of atrophic AMD,including slight change,focal increase pattern,patchy pattern,linear pattern,lacelike pattern,reticular pattern,and speckled pattern.In atrophic stage of atrophic AMD,geographic atrophy showed a well-defined hypoautofluorescence area;while non-geographic atrophy showed a ill-defined hypoautofluorescence area.There were three abnormal FAF patterns(focal,band and diffuse)in the junctional zone of geographic atrophy and diffuse pattern in the junctional zone of non-geographic atrophy. Conclusion FAF imaging is helpful for the diagnosis of atrophic AMD as a new non-invasive technique.
