The perfusion parameters of region of interest in renal cortex and medulla were obtained by CEUS offline data quantitative analysis software.

The perfusion parameters derived from CEUS quantitative analysis and Color Doppler parameter resistance index (RI) were not statistically different among renal function stabilization, acute rejection and chronic rejection groups (P>0.05); as compared with stable renal function group, there were marked reductions in peak intensity of cortex (PIc), peak intensity of medulla (PIm), ascending slope of cortex (a3c), ascending slope of medulla (a3m) and area under the curve of cortex (AUCc) in chronic rejection group. And mean transit time of cortex (MTTc) and mean transit time of medulla (MTTm) became significantly prolonged (P<0.05). Except for a3m, PIc and PIm were not significantly different between stable renal function and acute rejection groups (P<0.05).

Allogeneic hematopoietic stem cell transplantation was performed after inducted remission. The conditioning regimen was decitabine + FLAG + modified Bu/Cy. Prophylaxis of GVHD was performed with cyclosporine mycophenolate mofetil and short-term methotrexate. The patient received 11.73×108 mononucleated cells/kg and 17.59×106CD34+ cells/kg from donor. At Day 13 post-transplantation, neutrophils reached 0.5×109/L and platelet count was 20×109/L. Decitabine was prescribed since Day 50 post-transplantation monthly for 5 courses.

Samples were assayed for high-throughput NGS. Target analysis was used for functional pathways and screening target genes prediction. \u0000 \u0000 \u0000Results \u0000There were differentially expressed 908 mRNAs and 1228 lncRNAs between slow metabolic and fast metabolic groups (P<0.05). According to the abundance and difference, 22 up-regulated and 18 down-regulated mRNAs, 13 up-regulated and 24 down-regulated lncRNAs were selected. In addition to CYP3A5, CYP2C19, CYP1A2 and UGT1A1 might affect the metabolism of tacrolimus. At the same time, NONHSAT108617.2 in differentially expressed lncRNAs might regulate the expression of CYP3A5 gene. \u0000 \u0000 \u0000Conclusions \u0000This study has comprehensively analyzed the expression of lncRNAs in donor liver from pediatric liver transplantation. Some differentially expressed drug metabolism related genes may affect tacrolimus metabolism in vivo and thus the postoperative use of immunosuppressive drugs. \u0000 \u0000 \u0000Key words: \u0000Liver transplantation; Long noncoding RNA; Drug metabolism","PeriodicalId":9885,"journal":{"name":"Chineae Journal of Organ Transplantation","volume":"19 1","pages":"219-225"},"PeriodicalIF":0.0,"publicationDate":"2019-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72956441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
