Objective To verify the applicable significance of confocal scanning laser retinal tomography in age-related macular degeneration (AMD). Methods Heidelberg confocal scanning laser tomography was used to measure 75 eyes of 59 patients with AMD, including 25 eyes of 20 patients with exudative AMD, 25 eyes of 16 patients with atrophic AMD , and 25 eyes of 23 patients with macular drusen. The differences of the width, volume and maximum height of Z profile signal of macula were analyzed. Results Z profile signal width in macular tomography of exudative AMD was wider than that of macular drusen; maximum height and volume in macular tomography of exudative AMD were larger than that of macular drusen (P

Objective To discuss the image of indocyanine green angiography (ICGA) about high myopia. Methods Tweenty seven patients (54 eyes) with high myopia underwent ocular examination, fundus color photography, simultaneous ICGA and fluorescein angiography (FFA) with the confocal scanning laser ophthalmoscope.The findings for the two modes of amgiographies were compared. Results Lacquer crack was evident on ICGA in 19 eyes among which the focal, plaque choroidal neovascularization (CNV) were apparent in the middle part of lacquer cracks in 10 eyes (52.6%) .In comparison the lacquer cracks were seen in only 7 eyes on FFA. Choroidal capillary atrophy was seen on ICGA and FFA in 14 eyes and ICGA shew thick choroidal vessels in 3 eyes. Conclusion ICGA is superior to FFA for showing choroidoretinal degeneration and atrophy,lacquer crack and CNV in high myopic eyes, and conduce to evaluating prognosis.

Purpose To discuss changes of macular choriocapillaris hemodynamics in AMD. Methods Eighty six eyes of 86 patients underwent ICGA,including macular drusen in 15 eyes of 15 patients,exudative AMD in 52 eyes of 52 patients,atrophic AMD in 19 eyes of 19 patients,for the observation of macular choriocapillaris perfusion. Results Choriocapillaris filling phase (CFP) of exudative AMD was obviously longer than that of eyes with normal, atrophic AMD and drusen groups ( P

ObjectiveTo observe and estimate the image characters of indocyanine green angiography (ICGA) and fundus fluorescein angiography (FFA) in atrophic age-related macular degeneration(AMD) and macular drusen.MethodsFFA, ICGA and fundus photography were performed on 95 eyes of 73 atrophic AMD patients, including 19 patients (26 eyes) with depigmentation and atrophy of retinal pigment epithelium (RPE), 15 (30 eyes) with macular drusen, and 39 (39 fellow eye) with unilateral exudative AMD. ResultsIn 26 eyes with depigmentation and atrophy of RPE, the result of FFA of 24 eyes with depigmentaion showed patch hyperfluorescence, and of ICGA showed patch hyperfluorescence and hypofluorescence on the late photographs; in 2 eyes with maplike atrophy of RPE, the result of FFA showed patch hyperfluorescence, and of ICGA showed choriocapillaris defect with sharply demarcated boundaries and hypofluorescence of large choroidal vessels. In 30 eyes with macular drusen, the result of FFA of 8 eyes with hard drusen showed hyperfluorescence, and of ICGA showed patch and spot hyperfluorescence; the result of FFA of 16 eyes with soft drusen showed hyperfluorescence, and of ICGA showed persistent patch hypofluorescence intermixed with cluster hyperfluorescence; and the result of FFA of 6 eyes with both soft and hard drusen showed hyperfluorescence, and of ICGA showed patch hyperfluorescence intermixed with hypofluorescence. When it was hypofluorescence in ICGA in patients with macular drusen, larger quantity and range of fluorescence were found in FFA than in ICGA; when it was hyperfluorescence in ICGA, smaller quantity and range of fluorescence were found in FFA than in ICGA. In 39 fellow eyes of unilateral exudative AMD, 32 or 31 eyes, examined by ICGA or FFA, had abnormal fluorescence of drusen and depigmentation and atrophy of RPE damage.ConclusionsSimultaneous examination of ICGA and FFA can be useful for accurate evaluation of fundus image characters of types of angiography in atrophic AMD.

AIM: To investigate the relationship between NF-?B activation and intimal hyperplasia.METHODS: The protein extract from aorta was used to detect the expression of NF-?B p65,I?B?,ICAM-1 and COX-2 by Western blotting,and detection of threonine phosphorylation of p65 was performed by immunoprecipitation analysis.RESULTS: The level of p65 reached a maximum level at day 7,and then decreased significantly,which was higher than that in the control,in both cellular extract and nuclear extract at day 21 after balloon injury.The p65 level in cytoplasm had no obvious changes at different time points after balloon injury.The threonine phosphorylation of NF-?B p65 was negative correlated with the nuclear translocation of NF-?B.I?B? level showed a 15% decrease at day 1 after balloon injury,compared with control group,then returned at day 14,and reached to normal level at day 21.However,the expression of ICAM-1 and COX-2 was maximal at day 14,and then declined but higher than that in control group at day 21 after balloon injury.CONCLUSION: The activation of NF-?B p65 and the expression of ICAM-1 and COX-2 are parallel to the neointimal thickening after balloon injury.

Objective To describe the psychological experience of the patients with end-stage cardiopathy in China. Methods Phenomenology method was used in the study. Fifteen end stage cardiopathy patients received a non-structured interview. Results Four themes were extracted including heavy psychological burden about the disease and the selection of treatment options; complex psychological responses to families and relatives; wishing of social support;lose heart to personal future and prospects. Conclusions The patients on the end stage cardiopathy have complicated and intensive psychological responses. Medical staff should focus on the emotional of these patients, and provide effective strategies to promote patients'physical and psychological rehabilitation.

Serum levels of CXC chemokine ligand 10 (CXCL10) and chemokine receptor 3 (CXCR3) were determined in 50 patients with type 1 diabetes mellitus (T1 DM) and 30 normal control subjects by ELISA method.The results showed that serum levels of CXCL10 and CXCR3 in T1DM patients were significantly higher than those in normal subjects [(258.17 ± 39.12 vs 96.47 ± 26.91) ng/L,(851.87 ± 70.04 vs 441.82 ± 72.24) pg/ml,both P＜0.05].Serum level of CXCL10 in patients dropped sequentially with durations of diabetes ＜6 weeks,≥6 weeks or ＜3 years,and ≥ 3 years,being statistically significant between groups (P＜0.05).These results suggest that serum levels of CXC10 and CXCR3 may reflect the immune activity in T1DM.

Objective To investigate the role of lysyl oxidase (LOX) in synovitis and cartilage destruction by comparing the expression of LOX in synovial fluid and synovium of active rheumatoid arthritis (RA) and active osteoarthritis (OA).Methods LOX in the synovium was detected by immunohistochemistry from 14 patients with active RA,24 patients with active OA and 20 patients with knee injury (the control group).LOX in the synovial fluid was measured by enzyme linked immunosorbent assay (ELISA) from 14 patients with active RA and 24 patients with active OA.T-test was used for statistical analysis.Results The level of LOX expression in active RA synovium (0.012±0.007) was similar to that in active OA synovium (0.013±0.011,P＞0.05).But the expression of LOX in synovium of active RA and active OA was significantly higher than that in synovium of the control group (0.003±0.004,P＜0.01).The amount of LOX in the synovial fluid of active RA [(1.9±1.4) μg/ml] was significantly higher than that of active OA [(1.0±0.4) μg/ml,P＜0.05].Conclusion High expression of LOX in the synovial fluid and synovium of active RA and active OA suggest that LOX may be involved in chronic synovitis and cartilage destruction,and may be related with the extent of synovitis and cartilage destruction.
