BACKGROUND: Umbilical cord mesenchymal stem cells (UC-MSCs) have made certain curative effect on hepatic failure, but little is reported on the effect of hepatic failure patient's serum microenvironment on UC-MSCs differentiation ability. OBJECTIVE: To investigate the effect of hepatic failure patient's serum on the differentiation of umbilical cord mesenchymal stem cells into hepatic cells. METHODS: UC-MSCs were isolated by tissue adherent method and the cell morphology and phenotype identified by microscope and flow cytometry. Alpha-MEM media with serum before/after plasmapheresis were used to culture the hirdgeneration of UC-MSCs, and regular fetal bovine serum culture medium acted as control group. Inverted microscope was used to observe the cell morphology in three groups. Immunohistochemical method was used to measure expression level of alpha fetoprotein, albumin and cytokeratin 18. RESULTS AND CONCLUSION: A great amount of high-purity UC-MSCs could be obtained using tissue adherent method, which highly expressed CD44, CD73, CD90, CD10, but did not express CD45. Hepatic failure patient's serum could change the morphology of UC-MSCs and induce UC-MSCs to express alpha fetoprotein, albumin and cytokeratin 18. The positive expression of alpha fetoprotein, albumin and cytokeratin 18 was significantly increased after plasmapheresis (P < 0.05). To conclude, hepatic failure patient's serum after plasmapheresis exert more benefits to induce UC-MSCs to differentiate into hepatic cells than that before plasmapheresis.

Objective To investigate the whole genomic expression profiles of chronic atrophic gastritis with interleukin(IL)-1β-31CC/-511TT genotype as measured by oligonucleotide microarray technique.Methods Genomic RNA was extracted from gastric biopsies of 12 patients with chronic atrophic gastritis(6 with IL-1β-31CC/-511TT and 6 with IL-1β-31TT/-511CC).The genomic profiles of IL-1β gene polymorphisms 31CC/-511TT and 31TT/-511CC were compared and tested for differential expressed genes associated with 31CC/-511TT using Agilent human whole genomic oligonucleotide microarrays.The results were further analyzed in terms of gene ontology(GO).Results There were 200 differentially expressed genes associated with IL-1β-31CC/-511TT,159 of which were up-regulated and 41 were down-regulated.These genes mainly involved in macromolecule metabolic process,post-translational protein modification,ubiquitin cycle,and protein kinase cascade.Five genes had biological activities,one of which was down-regulated gene(PCSK5)and 4 were upregulated genes(PRKCA,NPLOC4,TRIB3 and MAPKAPK3).Conclusions The chronic atrophic gastritis with IL-1β-31CC/-511TT genotype has molecular phenotypes which is associated with malignance and inflammation.These individuals are needed more intensive preemptive treatment and dynamic surveillance.

Objective To investigate the association of IL-23R and IL-12B polymorphisms with susceptibility to psoriasis in Chinese Han population. Methods Patients with psoriasis were recruited based on the diagnostic criteria. In the first phase of the study, three SNPs (rs6887695, rs11465817 and rs1343152)were genotyped in DNA samples from 217 unrelated patients with psoriasis as well as 288 control subjects by direct sequencing. The positive SNP rs6887695 was validated in a larger combined sample including 578 patients with psoriasis and 1422 human controls, by using Taqman fluorescent PCR. The data were assessed by Hardy-Weinberg equilibrium test, chi square test, haplotype analysis and logistic regression model analysis. Results There was a significant difference in the allele frequency of SNP rs6887695 ( OR = 1.33, 95% CI 1.03 - 1.73,P = 0.028) of IL-12B between patients and controls, but not in that of the other two SNPs, rs11465817 and rs1343152 of IL-23R (P > 0.05 ). Hardy-Weinberg test showed that there was a linkage disequilibrium between rs11465817 and rs1343152 SNPs (D' = 0.744, r2 = 0.281 ); further analysis revealed a risk haplotype for psoriasis (A-A: OR = 2.890, P = 0.0018) constructed with 2 risk alleles of rs11465817 and rs1343152. Conclusions The susceptibility to psoriasis seems to be associated with the SNP rs6887695 of IL-1B gene but not with the SNPs rs11465817 or rs1343152 of IL-23R gene in Chinese Han population. The A-A haplotype of rs11465817-rs1343152 in IL-23R gene may increase the risk of psoriasis in Chinese Han population.
