ABSTRACT
Objective To assess the impact of physical training on physiological function of adult renal transplant recipients by meta-analysis and to provide theoretical guidance for clinical practice.Methods Randomized controlled trials of physical training for the treatment of renal transplant recipients until October 2017 were searched in the database of Cochrane library,PubMed,Embase,Web of Science,Wanfang Data and CNKI.Data extracted from the literatures were analyzed with RevMan software (version 5.3).Results A total of 10 studies in 10 manuscripts met the inclusion criteria,and 557 cases were included.Meta-analysis results were as follows.Compared with the control group (routine drug therapy),the level of peak exercise oxygen uptake (peak VO2) was significantly increased in physical training group (routine drug therapy and physical training) (MD=2.40,95％ CI 0.15-4.64,P=0.04).However,there was no statistically significant difference in the change of blood lipid,blood pressure,hemoglobin and serum creatinine between the two groups (all P ＞0.05).Conclusions Physical training can improve cardio respiratory fitness of renal transplant recipients in the early stage,but it has no obvious effect on blood pressure,blood lipid,hemoglobin and blood creatinine.
ABSTRACT
Objective To investigate the effect and the mechanism of epithelial-mesenchymal transition (EMT) in renal tubular cells induced by uric acid.Methods Normal rat kidney tubular cell line (NRK-52E) were exposed to different concentrations of uric acid (100,200,400,600,800 μmol/L UA) for 48 hours to induce EMT.Morphological changes of the NRK-52E cells were examined under an inverted phase contrast microscope.The protein expression of E-cadherin,α-SMA,p-Akt and Akt were detected by Western blotting.The distribution of E-cadherin and α-SMA were detected by immunofluorescence.NRK-52E cells were pretreated by different concentrations of LY294002(0,2.5,5,10,15 μmol/L),the inhibitor of PI3K/p-Akt signaling pathway,and then processed by uric acid (400 μmol/L) for 48 hours.Western blotting was used to detect the protein expression of p-Akt and Akt.NRK-52E cells were then divided into four groups:normal group (N),uric acid group (UA),LY294002 group (LY),uric acid with LY294002 group (UA + LY).The protein expression of E-cadherin and α-SMA were detected by Western blotting,the distribution of E-cadherin,α-SMA and p-Akt were detected by immunofluorescence.Results There was abundant cellular expression of E-cadherin in unstimulated renal tubular cells whereas its expression was significantly decreased in uric acidstimulated cells (P ＜ 0.05).In addition,uric acid induced de novo expression of α-SMA in contrast to almost negative staining in untreated cells (P ＜ 0.05).p-Akt were obviously increased in high uric acid group (P ＜ 0.05) and Akt changed not significantly (P ＞ 0.05).NRK-52E cells transformed into elongated fibroblast-like cells from cuboidal clustered epithelial cells.These indicated that uric acid has induced EMT and activated PI3K/p-Akt signaling pathway in NRK-52E cells.However,the above effects of uric acid were abolished when p-Akt was blocked by the PI3K inhibitor (10,15 μmol/L LY294002),indicated that LY294002 has reversed the trend of EMT.Conclusions High uric acid induces phenotypic transition of renal tubular cells probably via activating PI3K/Akt signaling pathway.
ABSTRACT
Objective Macrophage activation syndrome (MAS) is a severe, potentially life-threatening clinical condition. The clinical features including precipitating events, clinical presentations, treatment strategies, outcome in systemic onset juvenile idiopathic arthritis (So-JIA) children with MAS were reviewed. Perforin A91V gene analysis was also performed. Methods Retrospective review of fourteen MAS cases with So-JIA from 2003 to 2008 from a collected database. Gene-specific polymerase chain reaction ( PCR) primers were used to analyze the perforin A91V gene polymorphism. Results Fourteen patients with age from 4 months to 12 years were considered to have evidence of MAS. Nine of them were boys. The primary diagnosis was systemic onset juvenile idiopathic arthritis. No medication was identified as trigger. Eleven of them had infections prior to MAS. Among them specific infectious agents were identified in four patients. High fever, new onset of hepatosplenomegaly, lymphadenopathy, liver function abnormality, abnormal lipid metabolism and hemophagocytosis were common clinical features. Two cases presented with acute respiratory distress syndrome (ARDS). Multiple organ failure (MOF) occurred in three cases. Three patients died. The variant form (NCBI: SNP rs35947132) of perforin A91V gene was detected in seven systemic onset juvenile idiopathic arthritis compolicated with MAS cases. However no mutation was detected. Clucocorticoid, intravenous immunoglobulin, immunoimpressive therapy were effective treatment of this condition. Plasmapheresis (HP) was successfully used in one case with severe MAS. Conclusions MAS is a rare and potentially fatal complication of childhood rheumatoid diseases such as systemic onset juvenile idiopathic arthritis. In this series, majority of them were male and most of them were preceded by infection. Bone marrow studies support the diagnosis. MOF may be a poor prognostic sign of So-JIA. Aggressive and early therapy is essential. There is no relationship between the variant form (NCBI: SNP rs35947132) of perforin A91V gene and So-JIA with MAS in this small sample's study. More research need to be done by increasing sample's numbers.

Objective To analyses the mutation of connexin30gene in a pedigree with hidrotic ec-todermal dysplasia(HED).Methods Blood samples were obtained from18affected and16normal individ-uals in this family.Mutation scanning was carried out by PCR and direct sequencing.Results A transition,at position on connexin30gene31(G→A),leading to a missense mutation(G11R),was detected in18patients,but was not found in16normal individuals in this HED family and in188unrelated,population-matched control individuals,which indicated that it did not represent common polymorphism.Conclusion A missense mutation(31G→A)in the connexin30gene has been determined in the pedigree with HED,which is probably one of the molecular bases of the pathogenesis of the disease.
ABSTRACT
Objective To detect ED1 gene mutations in the families with X-linked hypohidrotic ec-todermal dysplasia (XLHED). Methods Blood samples were obtained from 2 pedigrees. All 8 exons and flanking intronic boundaries of ED1 gene were amplified with polymerase chain reaction technique and then directly sequenced. Results Two mutations were found in ED1 gene. One was splicing mutation (IVS8+5 del G), the other was missense mutation (A959G). None of the mutations was found in normal individuals of two XLHED families and in 188 unrelated, population-matched control individuals. Conclusion Out of the ED1 gene mutations identified in 2 Chinese XLHED families, IVS8+5del G is a novel mutation.
