Objective To carry out the detection of JAGI gene in children with chronic cholestasis and to im-prove the diagnostic level and understanding of Alagille syndrome. Methods Two cases of chronic cholestasis with multiple organ involvement were selected as the research subjects and their clinical data,laboratory test results were col-lected. Two milliliter peripheral intravenous heparin anticoagulan blood was drawn from each patient. All fragments of 26 exons of the JAGI gene were amplified by polymerase chain reaction - sequence based on typing method. Results One patient with chronic cholestasis,heart murmur and dysmorphic face showed bile duct paucity in liver biopsy and a novel heterozygous mutation c. 809 809delG(p. G270Dfs*142)in 6 exon. Abnormal amino acid replaced JAG1 protein and resulted in truncation of the JAG1 protein. The part of epidermal growth factor(EGF)like repeats region loss and the cysteine rich region completely lost. One case with typical chronic cholestasis and dysmorphic face showed a known IVS20 - 2 5delTAAG heterozygous mutation which resulted in splice site changes. Conclusion A novel JAGI gene mutation c. 809 809delG(p. G270Dfs*142)is helpful to screen JAGI gene of Notch signal transduction pathway for chronic cholestasis with multiple organs involvement in children.

AIM:To explore the clinical value of combined detection of C-reactive protein ( CRP ) , erythrocyte sedimentation rate ( ESR) and white blood cell ( WBC) count in patients with ocular syphilis.
METHODS:Dates of CRP, ESR, WBC, TPPA and RPR of 51 ophthalmopathy patients caused by syphilis and 50 normal control from Jan. 2012 to Dec. 2015 in eye hospital were recruited and analyzed statistically.
RESULTS:The positive rates of CRP, ESR and WBC of oculopathy patients were 16%, 18% and 39%, respectively, which were higher than those in the control group. In patients group, the positive rate of ESR was higher than CRP and WBC. There were no obvious relationships between RPR titers and positive ratios of CRP, WBC and ESR.
CONCLUSION: The blood level of CRP, WBC and ESR may have certain help in estimating and monitoring condition of patients with ocular syphilis.
