A new Monte Carlo transport code RMC has been being developed by Department of Engineering Physics, Tsinghua University, Beijing as a tool for reactor core analysis on high-performance computing platforms. To meet the requirements of reactor analysis, RMC now has such functions as criticality calculation, fixed-source calculation, burnup calculation and kinetics simulations. Some techniques for geometry treatment, new burnup algorithm, source convergence acceleration, massive tally and parallel calculation, and temperature dependent cross sections processing are researched and implemented in RMC to improve the effciency. Validation results of criticality calculation, burnup calculation, source convergence acceleration, tallies performance and parallel performance shown in this paper prove the capabilities of RMC in dealing with reactor analysis problems with good performances.

This study retrospectively evaluated the effectiveness and safety of traditional Chinese medicine Shenqilixin Formula (SQLXF) as an adjunctive intervention for treating patients with chronic heart failure (CHF).This retrospective study included 135 patients with CHF. They were allocated to a treatment group or a control group according to the different treatments they received. Seventy five patients in the treatment group underwent SQLXF plus routine treatment, while 60 subjects in the control group received routine treatment only. The primary outcome was cardiac function. It was measured by the left ventricular end diastolic diameter (LVDD), left ventricular ejection fraction (LVEF), cardiac output (CO), every cardiac output (ECO), and cardiac index (CI). The secondary outcome included motor function. It was measured by the standard 6-MinuteWalk Test (6MWT). In addition, adverse events (AEs) were also recorded.Compared to subjects in the control group, patients in the treatment group revealed greater effectiveness in cardiac function, measured by LVEF (P < .05), CO (P < .05), and ECO (P < .05), and motor function, measured by the 6MWT scale (P < .05). Moreover, no significant differences of AEs were found between the 2 groups.SQLXF as an adjunctive therapy to routine treatment may help to improve both cardiac and motor function in patients with CHF.
