A 32-year-old woman with a history of acute hepatitis at age 9 years was found to have jaundice during pregnancy in 2008, and was diagnosed as having intrahepatic cholestasis of pregnancy. In 2009, she underwent cholecystectomy for gallstones and chronic cholecystitis. However, itching and jaundice did not resolve postoperatively. She was admitted to our hospital with fatigue, jaundice, and a recently elevated γ-glutamyl transpeptidase level. Liver biopsy led to the diagnosis of biliary cirrhosis with ductopenia. Genetic testing revealed a pathogenic heterozygous mutation, ex13 c.1531G > A (p.A511 T), in the ABCB4 gene. Her father did not carry the mutation, but her mother's brother carried the heterozygous mutation. We made a definitivediagnosis of familial intrahepatic cholestasis type 3. He symptoms and liver function improved after 3 mo o treatment with ursodeoxycholic acid.展开更多

METHODS： An assay using oligonucleotide chip was developed for detection of HBV genotypes in serum samples from HBV DNA-positive patients in Eastern China. This method is based on the principle of reverse hybridization with Cy5-labeled amplicons hybridizing to type-specific oligonucleotide probes that are immobilized on slides. The results of 80 randomly chosen sera were confirmed by direct sequencing. RESULTS： HBV genotype B, C and mixed genotype were detected in 400 serum samples, accounting for 8.3% （n = 33）, 83.2% （n = 333）, and 8.5% （n = 34）, respectively. The evaluation of the oligonucleotide assay showed 100% concordance with the amplicon phylogenetic analysis except 9 mixed genotype infections undetected by sequencing. CONCLUSION： The study indicates that HBV genotype C and B prevail in the Eastern China. It is suggested that the oligonucleotide chip is a reliable and convenient tool for the detection of HBV genotyping.展开更多

The levels of inflammatory cytokines and oxidative stress response indicators in serum as well as the expression of inflammation and oxidative stress signal molecules in peripheral blood were measured before treatment and 3 d after treatment.Results:Compared with those of same group before treatment, serum TNF-α, CysLTs, sTREM1, sP-selectin, sICAM1, MDA, SF and COR levels as well as peripheral blood TLR4, NF-κB, COX2, NOX4, MPO and iNOS expression intensity of both groups of patients significantly decreased whereas SOD and IgA levels significantly increased after treatment. Moreover, serum TNF-α, CysLTs, sTREM1, sP-selectin, sICAM1, MDA, SF and COR levels as well as peripheral blood TLR4, NF-κB, COX2, NOX4, MPO and iNOS expression intensity of experimental group were lower than those of control group whereas SOD and IgA levels were higher than those of control group. Conclusion: Early warning and evidence-based intervention combined with drug therapy can reduce the inflammatory response and oxidative stress response in the infection process of children with mycoplasma pneumonia.展开更多
