Objective: To investigate the prevalence and characteristics of pathogenic variants in complement genes in Han Chinese children with atypical hemolytic uremic syndrome (aHUS). Method: Eleven Han Chinese children with aHUS, including 9 boys and 2 girls aged between 1 year and 4 months and 13 years, were investigated in Department of Pediatrics, Fuzhou General Hospital, from November 1998 to February 2014. Analysis of variants of all the exons of 10 complement genes (CFH, MCP, CFI, C3, CFB, CFHR1, CFHR2, CFHR3, CFHR4 and CFHR5), including 25 bases from 3′ end and 25 bases from 5' end, was performed in the 11 cases by targeted sequence capture and next generation sequencing. Significant variants detected by next generation sequencing were confirmed by Sanger sequencing. To understand pathogenicity of variants found in the captured genes, we investigated genetic conservation by multiple protein sequence alignment among different species, and analyzed whether the variants were located in protein domains or not, and investigated functional significance by functional computational prediction methods. Result: Twenty-seven percent of Han Chinese children with aHUS carried pathogenic variants in the 10 complement genes. Pathogenic variant CFB 221G>A (R74H) was detected in Patient 3 and Patient 9, which was not found in parents of Patient 3′ , and was found in healthy father of patient 9. Pathogenic variant CFHR5 242C>T (P81L) was found in Patient 2, and was found in healthy father of patient 2. However, no pathogenic variants in genes CFH, MCP, CFI, C3, CFHR1, CFHR2, CFHR3 and CFHR4 were identified. Conclusion Pathogenic variants in the 10 complement genes were identified in 3/11 of Han Chinese children with aHUS in our study and CFB was the most frequently mutated gene.

Objective To investigate the expression of IL-6/STAT3 signal pathway induced by lipopolysaccharide (LPS) on human intrahepatic biliary epithelial cells (HiBECs) in vitro.Methods The HiBECs were cultured in vitro.The cells were stimulated by LPS at different concentrations (0,0.1,1,2,4,8 μg/ml) and different time (24,48,72 h).The expression of IL-6 was measured by ELISA to determine the best concentration and time of LPS.Then we chose the best concentration and time of LPS to intervene the cells in the further experiments.The levels of mRNA expression of c-Myc and Mcl-1 were detected by fluorescence quantitative reverse transcrption PCR (RT-qRCR).The proportion of p-STAT3/STAT3 protein and the expression of c-Myc and Mcl-1 protein in HiBECs were analyzed by Western blot.Results LPS upregulated the expression of IL-6, and reached its peak at 4 μg/ml and 24 h(F=16.492,17.763,P<0.001,P<0.01).LPS increased the mRNA expression of c-Myc and Mcl-1(P<0.01).Meanwhile, The ratio of p-STAT3/STAT3 (P<0.05) protein and the expression of c-Myc (P<0.001) and Mcl-1 (P<0.05) protein were upregulated after stimulating with LPS.Conclusion The IL-6/STAT3 signal pathway can be activated by LPS in HiBECs, and LPS may promote the expression of c-Myc and Mcl-1 through this signal pathway.
