Structural shifts in the intestinal microbiota of rats treated with cyclosporine A after orthotropic

Frontiers of Medicine 2019, Volume 13, Issue 4,   Pages 451-460 doi: 10.1007/s11684-018-0675-3

Abstract: Understanding the effect of immunosuppressive agents on intestinal microbiota is important to reduce the mortality and morbidity from orthotopic liver transplantation (OLT). We investigated the relationship between the commonly used immunosuppressive agent cyclosporine A (CSA) and the intestinal microbial variation in an OLT model. The rat samples were divided as follows: (1) N group (normal control); (2) I group (isograft LT, Brown Norway [BN] rat to BN); (3) R group (allograft LT, Lewis to BN rat); and (4) CSA group (R group treated with CSA). The intestinal microbiota was assayed by denaturing gradient gel electrophoresis profiles and by using real-time polymerase chain reaction. The liver histopathology and the alanine/aspartate aminotransferase ratio after LT were both ameliorated by CSA. In the CSA group, the numbers of rDNA gene copies of cluster I, cluster XIV, and Enterobacteriaceae decreased, whereas those of increased compared with the R group. Cluster analysis indicated that the samples from the N, I, and CSA groups were clustered, whereas the other clusters contained the samples from the R group. Hence, CSA ameliorates hepatic graft injury and partially restores gut microbiota following LT, and these may benefit hepatic graft rejection.

Fatigue analysis of steel box girder in key sections for threetower suspension bridge under random vehicle load

Chen Ce,Ji Bohai and Liu Rong

Strategic Study of CAE 2012, Volume 14, Issue 5,   Pages 75-79

Abstract:

Taizhou Bridge is the first kilometer level threetower and twospan suspension bridge in the world. The three-dimensional fullbridge FEM (finite element method) model of the Taizhou Bridge and the random vehicle loading on the bridge finite element model by simplified vehicle load model are established. The vertical displacement and bending moment values are calculated to analyze the position of the maximum stress for the steel box girder under vehicle load. Then the critical position can be determined to carry out fatigue analysis for the steel box girder.
