Background The main cause of X linked juvenile retinoschisis is mutation of RS1 gene.The phenotype of X linked juvenile retinoschisis is associated with the mutation types of RS1 gene.However,the relationship of genotype and phenotype of X linked juvenile retinoschisis is unclear.Objective The present study was to survey the clinical phenotype of X-linked juvenile retinoschisis in twelve Chinese families with eleven different mutations in the XLRS1 gene. Methods Complete ophthalmic examinations with slit lamp biomicroscopy,fundus examination and Dhotography were carried out in 28 affected males.Ganzfeld electroretinography (ERG),fundus fluorescein angiography,A and B-scan standardized echography and optical coherence tomography(OCT)were also performed in some patients.The coding regions of the XLRS1 gene that encodes retinoschisin were amplified by polymerase chain reaction(PCR)and analyzed by the single strand conformation polymorphism(SSCP)assay.The RS1 gene mutations were determined by direct sequencing in an automated sequencer.Written informed consent wasobtained prior to the survey. Results The 28 affected males showed a typical foveal schisis with or without peripheral retinoschisis.The typical response to white single flash ERG was seen with a reduction of the b-wave amplitude and a relative preservation of the a-wave amplitude.causing a reduced b/a ratio in the male patients.A total of eleven different XLRS1 mutations in 12 families were identified,four of these mutations,including one frameshift mutaion(22 del T)of exon 1,Asp145His,Arg156Gly and Trp163X mutations of exon 5,were first described in this survey.One non-disease-related polymorphism(NSP),or the 576C to T(Pro192Pro)change of exon 6 was also newly reported herein.In the families with a frameshift(22 del T)mutation of exon 1,a splice donor site mutation(IVS1+2T

Objective To explore the expressions of circulating microRNAs (miRNAs) in acute liver failure mice induced by D-galactosamine (GalN)/lipopolysaccharides (LPS) and the correlation with miRNAs in the liver.Methods Forty clean grade Balb/C mice,with 32 in the model group and 8 in the control group were enrolled in the study.Liver failure was induced by intraperitoneally injection of D-GalN and LPS in mice of the model group,while mice of the control group were intraperitoneally injected with 1 mL 0.9 % sodium chloride solution.Serum and liver samples were collected at 0,3,5,7 hours following administration,and eight mice should be supplied to each sample,and changes of alanine aminotransferase (ALT),aspartate aminotransferase (AST) and histopathology of the liver were observed.miRNA from both the serum and the liver was extracted,miRNA expression profile in the liver at 0,5,7 hours by locked nucleic acid (LNA)-miRNA microarray was analyzed and miRNA by quantitative real-time reverse transcription polymerase chain reaction (RT-PCR) was detected.Means of the two groups were compared using one-way ANOVA and correlation analyses were performed using Pearson and Spearman correlation.Results Expression of miRNAs in the liver tissue changed significantly over time with the occurrence of acute liver failure in the mice.Twenty-one miRNAs were up-regulated and 27 were down-regulated,among which miRNA-122 and miRNA-1187 were down-regulated while miRNA-146a and miRNA-155 were up-regulated.It was confirmed by the PCR assay that the expression of miRNA-122 and miRNA-1187 in the liver gradually decreased,while those in the serum were up-regulated over time.However,the expressions of inflammation associated miRNA-155 and miRNA-146a were up-regulated both in the serum and the liver after administration.The expressions of miRNA-122 and miRNA-1187 were negatively correlated between serum and liver (r=-0.477,P=0.0089,r=-0.420,P=0.231),while the expressions of miRNA-155 in serum and liver were positively correlated (r=0.678,P=0.0001).Moreover,the expressions of miRNA-122 (r=0.571,0.554) and miRNA-1187 (r=0.471,0.542) were also positively correlated with serum levels of ALT and AST (all P<0.05).Liver and serum levels of miRNA-122 and miRNA-1187 changed significantly at 5 hours after administration,which preceded the changes of ALT/AST.Conclusions The expressions of miRNA-122 and miRNA-1187 in serum are well inversely correlated with the corresponding expressions in liver tissues during acute liver failure in mice.The changes of miRNA-122 and miRNA-1187 in the serum precede those of ALT/AST.These data suggest that serum miRNA-122 and miRNA-1187 might be the candidate serum biomarkers for early prediction of liver injury.

ObjectiveTo investigate the histological features as well as the factors influencing liver disease progression in Chinese patients with chronic hepatitis C (CHC). MethodsA total of 102 CHC patients who underwent percutaneous liver biopsy between August 2007 and May 2010 were recruited. Age, gender, body mass index (BMI) and transmission route of recruited patients were recorded. Serum levels of alanine transaminase (ALT) and aspartate transaminase (AST), HCV genotypes, HCV viral load and liver histological changes were detected. Statistical analysis was done by t test and Logistic regression. ResultsThe serum levels of ALT and AST in CHC patients with histological activity index (HAI) ≥4 were much higher, while platelet (PLT) counts were lower than those with HAI <4(t=2.209, 2. 298 and 2. 565, respectively; all P<0.05). Likewise, in patients with F≥3, the serum levels of ALT and AST as well as the mean age and the duration of infection were significantly elevated compared with F < 3 group ( t = 3.497, 2. 758, 2. 340 and 2. 570,respectively; all P<0. 05), while PLT counts were much lower (t = 2. 761, P=0. 007). The unvariate predictors for HAI≥4 were female, ALT>1 × upper limits of normal (ULN), AST level,F≥3, HCV RNA≥6 lgIU/mL and PLT counts. By mutivariate analysis, the Ishak stage score was the only independent predictor for HAI≥4 (OR 3.098, 95%CI 1.884-5. 092; P<0.01). Finally,the univariate predictors for F≥3 were age, BMI≥24 kg/m2 , ALT>1 × ULN, AST level, HAI≥4,PLT counts and duration of infection≥ 15 years. Multivariate analysis revealed that age (OR 1. 074,95%CI 1.006-1. 146; P=0.033), ALT level (OR 1. 035, 95%CI 1.015-1.055; P<0.01), ASTlevel (OR 0. 969, 95%CI 0. 948-0. 990; P=0. 005), the duration of infection ≥15 years (OR 37. 215, 95%CI 5. 816-238. 127; P<0.01) and HAI≥4 (OR 1. 939, 95%CI 1. 426-2. 636; P<0.01) were independent predictors for F≥ 3. ConclusionAge, ALT level, AST level, duration of infection≥15 years, HAI≥4 are independent predictors for liver fibrosis.
