RESUMO
Renal transplantation is still the most effective treatment for end stage renal disease up to date. Immunosuppression therapy can complicate the rejection and severe complications if it is used insufficient or excessive, which may lead to poor survival of patients and grafts . Currently and in the future, discovery of more sensitive biomarkers and better detection methods of allograft rejection and renal function is a major subject of clinical investigation and transplant medicine. This paper reviews the latest research progress in assessment of immune state and renal function after kidney transplantation.
RESUMO
AIM:To investigate the mechanism of microRNA-138-5p (miR-138-5p) inhibiting the proliferation,migration and invasion abilities of lung cancer cells.METHODS:The lung cancer A549 and H460 cells were transfected with miR-NC (control group) or miR-138-5p (experimental group).The bioinformatic analysis was performed to predict the target genes of miR-138-5p.The expression levels of miR-138-5p,forkhead box protein C1 (FOXC1) mRNA and vimentin mRNA were detected by RT-qPCR.The protein expression of FOXC1,vimentin,E-cadhcrin,N-cadherin and β-catenin was determined by Western blot.MTS method and colony formation assay were used to detect cell viability and proliferation ability.Wound healing assay and Transwell assay were used to detect cell migration and invasion ability.RESULTS:Over-expression of miR-138-5p significantly reduced the expression of FOXC1 and vimentin at mRNA and protein levels (P ＜ 0.05).The expression of E-cadherin and β-catenin were up-regulated and the expression of N-cadherin was down-regulated.The proliferation,migration and invasion abilities of the lung cancer cells were inhibited by the over-expression of miR-138-5p.CONCLUSION:miR-138-5p inhibits the proliferation,migration and invasion abilities of lung cancer cells by targeting FOXC1 and vimentin.It may be a potential target for lung cancer gene therapy.

RESUMO
OBJECTIVE@#By measuring lengths of tibias and fibulas in computed radiography (CR) of living body, regression formulae for stature estimation were obtained from these measurements that were adapted to the population of northern adults of Han.@*METHODS@#The length of tibias and fibulas were measured in radiography, including 422 subjects (207 men and 215 women). The body height of each subject was also recorded. Linear regression analysis between body height and the length of tibias and fibulas , analysis of variance of hypothesis test of linear regression model and t-test of the partial regression coefficient were applied to establish the regression equations for stature estimation. Then the paired t-test between the predictive value and the actual body height, the residual analysis, the tests of equal scedasticity and colinearity had been done to evaluate whether the equations accord with the model.@*RESULTS@#Thirty five regression equations which were statistical significant were obtained. The multiple correlation coefficient was from 0.909 to 0.823 and the standard error of the estimation was between 2.48-3.87 cm.@*CONCLUSION@#The lengths of tibias and fibulas on the CR films could be helpful to estimate stature. These equations could be used to estimate the body height of the Han population in North China.
