Objective To investigate the chang and impaction of TM and D- Dimer on peripherally inserted central catheter (PICC) associated thrombosis in cancer patients. Methods The expression of TM and D-Dimer from 207 cancer patients with PICC was examined using nzyme-linked immunoassay. Paitents were divided into thrombosis group and control group according to Doppler Sonography. Results The thrombosis group had 33 cases and the control group had 174 cases in 207 malignant tumor patients with PICC. Compared with that in control group, the expression of TM (6.806 ± 1.805)μg/L and D-Dimer (0.786 ± 0.294) mg/L was significantly higher in thrombosis group and respectively statistically significant (P<0.05), The expression of TM and D-Dimer was positively correlated with thrombosis respectively (r=0.572 and 0.530, P<0.05). The multi-factor Logistics analysis showed the odd ratio of TM was 1.899 and the odd ratio of D-Dimer was 7.292, and the difference was statistically significant (P<0.05). Patients were dichotomized into elevated and noneelevated groups according to the 50th percentile of the levels of TM and D-Dimer of the total study population. In multivariable analysis, the odd ratio of both elevated TM and elevated D-Dimer was 2.04, which was higher than elevated TM (1.286) alone and elevated D-Dimer (1.044) alone, and there was difference in statistics (P<0.05). The results showed that the risk of PICC associated with thrombosis in both elevated TM and elevated D-Dimer TM increased 2.042 times. The expression of TM and D-Dimer was correlated with clinical stage respectively (r=0.477 and 0.492, P<0.05);but was not correlated with age, sex, site of tumor and concurrent radiochemotherapy (P>0.05). Conclusions The expression of TM, D-Dimer is elevated, which is expected to assess the early diagnosis and clinical value of PICC associated thrombosis in cancer.

Model-informed drug development (MIDD) in the development of pediatric drugs is drawing more and more attention due to the insufficiency of subjects, lack of research on ontogeny, and the limitation of ethic. The core of MIDD used for dose selection includes the population pharmacokinetic (PopPK) model and physiologically based pharmacokinetic (PBPK) model, as well as model-based simulation and prediction. PBPK model has the advantage of predicting the optimal pediatric dose before the clinical trials and has the ability of extrapolation from adult model to pediatric model. PopPK model characterizes the pediatric PK feature based on the analysis of clinical data and can be used to explore the significant covariates, which is a power tool for individualized medicine in children. With their own advantages and disadvantages, PBPK and PopPK model should be jointly used in the pediatric drug development to refine the dose regimen for children at different ages. In this study, the pediatric drug development of rivaroxaban was taken as an example to introduce the combined application of PBPK model and PopPK model in the design and validation of pediatric dose regimen in Phase Ⅰ, Ⅱ and Ⅲ trials, which may provide reference to MIDD in other pediatric drug development.
