Background Fundus photography is a traditional method for detecting local retinal nerve fiber layer (RNFL) defects,but the evaluation of its result depends on the observer's experience.The spectral domain optical coherence tomography (OCT) exhibit the defects of RNFL very clearly.Objective This study was to evaluate the diagnosis value and correlation between topographic profiles of localized RNFL defects determined by spectral domain and time domain OCT with fundus photography.Methods Forty-one normal eyes of 41 subjects and 55 eyes of 55 glaucomatous patients with localized,wedge-shaped RNFL defects identified by two glaucoma specialists in fundus photographs were enrolled in the clinical study.The angular location and width of RNFL defects determined on the images of fundus photography,Cirrus HD-OCT and Stratus OCT were analyzed respectively using Pearson's correlation coefficient and linear regression analysis.This study followed the Helsinki declaration and was approved by Ethic Committee of Shenzhen Eye Hospital.Written informed consent was obtained from each individual before the clinical examination.Results Seventy-five RNFL defects were identified in 55 eyes by two glaucoma specialists unanimously with the defect position at superior-temporal and inferior-temporal quadrants.The sensitivity of Cirrus HD-OCT and Stratus OCT to determining RNFL defects were 88.0% and 69.3% respectively and their specificities were 92.7% and 97.6% respectively.The angular locations of RNFL defects by Cirrus HD-OCT and Stratus OCT were highly correlated with those by fundus photography(r=0.993,r=0.992,P<0.001);while the angular widths of RNFL defects by Cirrus HD-OCT and Stratus OCT were moderately correlated with those by fundus photography(r=0.420,r=0.432,P=0.019,P=0.002).No significant differences were found in the defect width of RNFL between Cirrus HD-OCT or Stratus OCT and fundus photography(Cirrus HD-OCT:P=0.114;Stratus OCT:P=0.074),and significant difference was found in that between Cirrus HD-OCT and Stratus OCT(P=0.002).Conclusion Spectral domain OCT and time domain OCT can localize RNFL defects with high sensitivity and specificity.The measure value of Cirrus HD-OCT and Stratus OCT for RNFL defects shows a good diagnostic agreement with fundus photography.

Objective To investigate the relationship between serum levels of alanine aminotransferase (ALT)or aspartate aminotransferase (AST)apportioned by the same hepatic parenchyma cell volume and liver histological necroinflammation grades in HBeAg-negative chronic hepatitis B (CHB)patients.Methods A total of 145 CHB patients were divided into four groups:Gl,G2,G3 and G4 based on the liver histological necroinflammation grade.The serum ALT and AST levels were determined by automatic biochemical instrument in these four groups.Furthermore,serum ALT and AST levels were then apportioned by the same hepatic parenchyma cell volume.The data were analyzed by ANOVA.Results Mean serum ALT levels in G1,G2,G3 and G4 groups were (35.3±29.1),(91.6±120.4),(111.6± 116.1)and (118.0±122.1)U/L,respectively,and the serum ALT levels apportioned by same hepatic parenchyma cell volume were ( 54.0 ± 45.1 ),( 144.2 ± 184.9 ),(191.3± 204.8)and (215.1 ± 226.5)U/L,respectively.The pairwise comparison between G1 and other three groups all showed statistically significant difference (P<0.05).Meanwhile,AST levels in G1 to G4 groups were (35.5± 29.0),(64.9±71.7),(96.0±81.9)and (102.8±77.0)U/L,respectively and the serum AST levels apportioned by the same hepatic parenchyma cell volume were (54.3±44.6),(102.3± 107.9),(165.2±148.7)and (189.4±145.4)U/L,respectively.The pairwise comparison between G1 and G3,G1 and G4,G2 and G3,G2 and G4 all showed statistically significant difference (P<0.05).Conclusion Both AST and ALT levels are sensitive indicators for liver inflammation grading in HBeAg-negative CHB patients during the natural history of the disease.

Objective:To establish the model of rats with UC by 2,4,6 trinitrobenzene sulfonic acid ( TNBS)/ethanol to understand the changes of IL-17,IL-23,TGF-β1,IFN-γin pathogenesis of ulcerative colitis (UC) and the impacts of mesalazine,mont-morillonite powder and clostridium on that.Methods:85 rats were divided randomly into 6 groups including the model ,mesalazine, montmorillonite,clostridium,mesalazine combined with montmorillonite powder group (15 rats per group ) and an additional control group of 10 normal rats.TNBS/ethanol was used to establish the model of rats with UC.The dosage of model, mesalazine, montmorillonite powder ,clostridium and mesalazine combined with montmorillonite powder were converted by surface area of rat and given to the rats by gastric-tube daily.All rats were executed at the 12th day of the molding and treatment ,and the blood and colon samples were collected.The content of IL-17,IL-23,TGF-β1,IFN-γwas measured in the blood by the ELISA method.The different changes of the four cytokines were compared separately.Results: ( 1 ) TNBS/ethanol was used to establish the model of rats with UC.The obvious inflammation can be observed on distal colon of rats by pathologic sections of HE stained .(2) The levels of plasma IL-17,IL-23 and IFN-γin the model,mesalazine,montmorillonite,clostridium and mesalazine combined with montmorillonite powder group were higher than ones in the control gruop (P<0.05),meanwhile,the levels of plasma TGF-β1 are lower (P<0.05).3.Comparing with the model group,the levels of plasma IL-17,IL-23 and IFN-γin the mesalazine,montmorillonite,clostridium and mesalazine combined with montmorillonite powder group were lower , and the levels of TGF-β1 were higer.The differences have statistic significative ( P<0.05).(4)Comparing the efficacy of treatment among mesalazine ,montmorillonite powder,clostridium and mesalazine combined with montmorillonite powder ,mesalazine and mesalazine combined with montmorillonite powder gets the best results ( P<0.05 ).The efficacy between montmorillonite powder and clostridium is similar.Conclusion:(1) TNBS/ethanol can be used to establish the model of rats with UC and can be successfully approved by the measurement of symptoms and pathologic investigation .(2)The IL-17,IL-23 and IFN-γare very active higher in the blood of rats with experimental ulcerative colitis induced by TNBS /ethanol, and have a positive correlation with inflammation.The TGF-β1 is in decrease in the blood of rats with colitis , and has a Negative Correlation with inflammation.(3)Mesalazine,montmorillonite powder,clostridium and mesalazine combined with montmorillonite powder may renovate the damage of inflammatory tissues of rats with experimental ulcerative colitis , and relieve the symptom of inflammation by reducing exudation of proinflammatory cytokines IL-17, IL-23 and immune regulatory cytokines IFN-γby producing the exudation of proinflammatory cytokines TGF-β1 to be good for recovery of UC.

OBJECTIVETo analyze the clinical characteristics and effects of rehabilitation treatment on hemophiliacs with iliopsoas hemorrage.
METHODSThe hemophilia patients with iliopsoas bleeding treated in Peking Union Medical College Hospital between January 2006 to December 2010 were enrolled. The clinical characteristics including symptoms, signs, complications, and rehabilitation treatment were analyzed retrospectively.
RESULTSAll of the forty-one hemophiliacs with iliopsoas bleeding were male, 20 cases wee the left bleeding, 18 the right, and 3 the bilateral. The median median age was 18 (6 - 61) years old(y). The median age of the iliopsoas bleeding for the first time was 17 (6 - 20) y. 34 patients accompanied with femoral nerve injury, 19 of them had secondary knee bleeding on the same side. 20 patents had quadriceps atrophy. Pelvic pseudotumor developed in 2 patients and permanent abnormal posture in 2 patients. The main finding of the ultrasound image was low-echo mass in iliopsoas muscles or inguinal region. 34 patients received rehabilitation therapy for 8 - 12 weeks under the support of factor replacement, complete hematomas absorption in 33 of them, with hip range of motion recovering back to baseline. 27 of 32 (84.4%) cases with femoral nerve injury got quadriceps strength above 4/5 grade, 20 cases of femoral nerve injury (62.5%) still had numbness on front of their thigh after treatment.
CONCLUSIONSIn this cohort of iliopsoas bleeding, most of the patients are adolescent. High prevalence of the femoral nerve injury and the secondary knee bleeding are found. Rehabilitation treatment under the support of factor replacement is safe and effective on hematoma absorption and neurological function recovery.
