Objective To study the diagnostic value of double-balloon endoscopy (DBE) and capsule endoscopy (CE) for small intestinal bleeding. Methods Overall detection rates of small intestinal bleeding with DBE, CE and the whole alimentary tract barium meal were compared. Positive rates of bleeding detection with DBE and CE were compared within the same patients. Influence of CE on one-procedure rate of DBE was analyzed. Results In 105 cases of small intestine bleeding, DBE detected 24 cases of Crohn's disease, 15 adenocarcinoma, 12 chronic nonspecific inflammation, 10 small intestinal ulcer of unknown reason, 8 entero-mesenchymoma, 8 polypus, 6 vascular deformation hemorrhage, 5 ancylostomiasis, 5 Mechel's diverticula ( including multiple diverticula), 3 lymphoma and 9 of no evident abnormalities. The positive detection rate of DBE is 91.4% (96/105). Disease detection rates of CE and whole alimentary tract barium meal were 75.0% (30/40) and 33.3% (25/75), respectively. The one-procedure rate of DBE is 90% (36/40) based on CE results, but it was only 69. 2% (45/65) according to clinic features and the whole alimentary tract barium meal. Conclusion The main causes of small intestinal bleeding are benign ulcers (including Crohn's disease) and tumor, as well as chronic inflammation. Polyps, vascular deformation, parasitosis, Mechel's diverticulum and lymphoma are the secondary causes.DBE is superior to CE in diagnosis of small intestine bleeding, but CE can increase the one-procedure rate of DBE.

Background Traction of epiretinal membrane results in macular morphologic change and visual functional impairment in eye with idiopathic epiretinal membrane (IERM),therefore figuring out their relationship is helpful for evaluation of disease prognosis.Objective This study was to observe the morphological change of macula and microstructure,and analyze the relationship between retina thickness,integrity of cone outer segment tips (COST) line in fovea and visual acuity.Methods This was a retrospective case-observational study.Fifty-six consecutive cases diagnosed as IERM in Zhongshan Ophthalmic Center from March 2011 to December 2011 were enrolled in this study,and all the patients showed unilateral IERM with the normal fellow eyes.Sixteen patients were males and 40 were females,with a mean age of (61.05 ± 6.58) years old.Spectral-domain optical coherence tomography (SD-OCT) examination was performed on the eyes,and Macular Cube (512×128) and HD 5 Line program were selected.Mean retinal thickness of central area (＜1 mm diameter),inner ring area (1-3 mm diameter) and outer ring area (＞3-6 mm diameter) of macula and the status of COST line (intact or fractured) was recorded.Mean thickness of whole macular areas and the difference of foveal microstructure were compared,and the correlation between retinal thickness and visual acuity was analyzed using Pearson linear correlation analysis.Related parameters including age,visual acuity,retinal thickness were also compared between the continuous COST lines group and the fractured COST lines group by independent sample t test.Results The flatted or disappeared fovea was seen in IERM eyes on the SD-OCT image.Retinal thicknesses were (446±89)μm,(418±64)μm and (328±34)ttm in the central area,inner ring area and outer ring area of macula in the IERM eyes,exhibiting significant increasing in comparison with (250±22) μm,(319±17) μm and (279±17) μm in the normal fellow eyes (t=13.370,9.523,7.769,all P =0.000).Significantly negative correlations were found between the visual acuity and the central macular thickness,inner ring thickness or outer ring thickness (r=-0.686,-0.653,-0.417,P＜0.05).In the IERM eyes,COST band was intact in 20 eyes and lack in 36 eyes.Compared with COST band intact group,aging,worse vision and increased retinal thickness were seen in the COST band absent group (t =2.109,P =0.039 ; t =-4.093,P =0.000 ; t =6.669,P=0.000;t=5.376,P=0.000;t=4.247,P=0.000).COST band was clear in all the normal fellow eyes on the SD-OCT image.Conclusions Increase of macular thickness and disruption of COST band reflect the visual function damage in IERM eye.Deficiency of COST band on OCT image seems to be an early indication of photoreceptor damage.Incomplete fovea COST band is often seen in older patients.

· AIM:To determine whether the multifocal visual evoked potential (mfVEP) can be used as a clinical method to assess the patients with optic nerve disease.· METHODS: Fifteen patients with optic nerve disease were examined in this study. All patients underwent visual acuity examination, slit-lamp inspection, ophthalmoscopy, Goldmann perimeter, fundus fiuorescein angiography, visual field and mfVEP. Although these patients with unilateral optic nerve damage,data from both eyes were included in the analysis.· RESULTS:In all patients the visual fields defect was demonstrated on the mfVEP and showed good correspondence in location of the scotoma. However, we also found some slight difference between visual field and mfVEP. In some locations, when the local visual fields were normal, mfVEP showed that its amplitude reduced. In reverse, when the local mfVEP seemed normal, visual field showed abnormity.· CONCLUSION:Multifocal visual evoked potential could be used as a clinical diagnosis option in patients with optic nerve disease. Local monocular damage to the optic nerve can be measured by an interocular comparison of the mfVEP.

Objective To explore the relationships between serum adiponectin,IL-6 and hypoxic-ischemic encephalopathy(HIE) degree in newborn infant.Methods Enzyme-linked immunoabsorbent assay was used to detect the serum adiponectin and IL-6 in 58 neonatal HIE and 26 neonates without HIE.And all the data were processed by SPSS 10.0 software.Results The level of serum adiponectin in moderate and severe HIE at acute stage were significantly lower than that of mild and control groups(Pa0.05).The level of serum IL-6 in moderate and severe HIE at acute stage were significantly higher than that of the mild and control groups(Pa0.05).The level of adiponectin were significant negative correlation with IL-6(r=-0.852 P

Authors described the patterns,core measures and mechanisms of coordinated care delivery in the localities and analyzed initial outcomes of this practice.It is found that such practice has optimized distribution of regional healthcare resources,implemented first visit to primary institutions, and the care delivery to separate emergency from outpatient service.In addition,the paper analyzed problems found in localities in terms of policy,public hospitals and primary institutions,and proposed elements required for coordinated care delivery system to succeed,such as enhanced policy support, enhanced multi-departmental coordination,and public hospital reform to explore feasible approaches.
