The correlation between tumor-associated macrophages and the prognosis of east Asian hepatocellular carcinoma patients: A systematic review and meta-analysis.

Background: Previous related studies have found that the levels of tumor-associated macrophages (TAMs) were correlated with prognoses in hepatocellular carcinoma. However, the prognostic value of TAMs for East Asian HCC patients remains inconclusive.

Methods: Our objectives were to systematically review the performance and explore the prognostic and clinical value of TAMs in patients with HCC.

Integrated numerical model of nitrogen transportation, absorption and transformation by two-dimension in soil-crop system.

A series of simulation experiments of nitrogen transportation, absorption and transformation were conducted, and the different cropping patterns of winter wheat and wastewater irrigation plans were taken into consideration. Based on the experiments, an integrated model of crop growth, roots distribution, water and nitrogen absorption by roots, water and nitrogen movement and transformation in soil-crop system by two-dimension was developed. Parameters and boundary conditions were identified and an effective computing method for optimizing watering and wastewater irrigating plans was provided.

A simulation analysis of the migration and transformation of pollutants contained in landfill leachate.

A dynamic composite model for a soil-water system that can be used to simulate the movement of leachate from a landfill. The composite model includes nine sub-models that trace water movement and the migration and transformation of five pollutants (organic N, NH4-, NO3-, NO2-, and Cl-) in saturated and unsaturated soil. The model to simulate the movement of leachate from a landfill in Laogang Town, Shanghai City was used.
