Objective To study the characteristics of optical coherence tomography (OCT) in idiopathic macular epiretinal membranes (IMEM) and the relationship between the thickness of fovea and the vision of affected eyes. Methods Total of 67 cases (73 eyes) with clinical diagnosis of IMEM by direct, indirect ophthalmoscopy, three mirror contact lens, fundus color photography or fundus fluorescein angiography(FFA) were examined with OCT. Results Epiretinal membranes(ERMs) with macular edema were found in 32 eyes, proliferative ERMs in 20 eyes, ERMs with macular pseudoholes in 14 eyes and ERMs with laminar macular holes in 7 eyes. Based on OCT, the ERMs were clearly and partially seperated from the retina (27 eyes, 38.36%), the retinal thickness of the fovea was the thickest in proliferative ERMs and the thinnest in ERMs with laminar macular holes. The statistical analysis showed there was a negative correlation between the thickness of fovea and visual acuity (r=-0.454, P= 0.000 ). Conclusion There were four types of image of OCT in IMEM: ERMs with macular edema, proliferative ERMs, ERMs with macular pseudohole and ERMs with laminar macular hole;and the thicker the fovea under the OCT, the poorer the visual acnity in the affected eyes with ERMs.

Objective To investigate the characteristics and analyze the differences of choroidal neovascularization (CNV) image between exudative age-related macular degeneration (AMD) and central exudative chorioretinopathy (CEC) using optical coherence tomography (OCT). Methods Twenty-three eyes of 22 patients with exudative AMD and 20 eyes of 19 patients with CEC, which were diagnosed as CNV using fundus fluorescein angiograph (FFA) or indocyanine green angiograph (ICGA), were exami- ned by OCT. The size of CNV and the thickness of retinal neurosensory layer in foveola were measured by OCT software. Results On OCT image, CNV had three main types of morphological features including simple CNV, CNV with serous retinal neurosensory layer detachment and CNV with choroidoretinal exudation. Exudative AMD mainly showed CNV with choroidoretinal exudation (56.52%) and CEC showed simple CNV (90 0%). The thickness of retinal neurosensory layer in foveola of patients with exudative AMD was thicker than that of patients with CEC and the size of CNV of patients with exudative AMD was larger than that of patients with CEC. Negative correlation was found between retinal neurosensory layer thickness in foveola and vision in both groups (?=-0.521, P =0.001). Conclusions There were certain discrepancy in morphology and area involved of CNV between exudative AMD and CEC on OCT images.

Objective To explore lymphocyte differentially expressed protein profile and its pathogenic significance in Huaihua Dong peoples with hypertension.Methods The lymphocyte protein profiles among 130 cases of blood specimen were detected and identified with matrix-assisted laser desorption ionization/time of flight mass spectrometry (MALDI-TOF-MS) and Mascot search against protein database.Results The reproducible protein-maps of two-dimensional gel electrophoresis were obtained among three groups.Compared with Dong normal peoples,the protein disulfide isomerase-related protein 5 and heat shock protein 27 showed higher expressions in the Dong peoples with hypertension (P < 0.01),but chain A,structure of haemoglobin in the deoxy quaternary state with ligand bound at the alpha haems is no statistical significance(P >0.05).Those three proteins were upregulated in Han peoples with hypertension (P <0.01).Conclusions The up-regulation of the protein disulfide isomerase-related protein 5 and heat shock protein 27 in the Dong and Han peoples with hypertension suggest that those two proteins might be associated with the occurrence and development of hypertension.

AlM: To explore the clinical therapeutic effect of the integrated traditional Chinese and Western medicine treatment of idiopathic panuveitis.
METHODS: Totally 47 patients ( 69 eyes ) with the idiopathic panuveitis were included in this study, which were randomly divided into control group and treatment group. Twenty-four cases (33 eyes) with the method of Western medicine-glucocorticoid and mydriatic were in control group, while 23 cases (36 eyes) with integrated traditional Chinese and Western medicine were in treatment group. Those patients were followed up 12-36mo, the vision before and after treatment, the therapeutic effects, the complications and the side effects of glucocorticoid were recorded.
RESULTS: Both of two groups' vision after treatment were improved, but the vision of treatment group was better than the control group. The effective rate and the cure rate of the treatment group were increased significantly. Of all of the complications, the incidence rate of complicated cataract and secondary glaucoma of the treatment group were reduced significantly. Of all of the side effects of glucocorticoid, the central excitation, hypertension and central obesity of the treatment group were reduced significantly (P<0. 05).
CONCLUSlON: Dialectical therapy of integrated traditional Chinese and Western medicine has better therapeutic effect than simple Western medicine treatment of idiopathic panuveitis, and could better reduce the side effect of glucocorticoid long-term use. lt is worthy applying in clinical practice.
