[Effects of Polystyrene Microplastics on Growth, Physiology, Biochemistry, and Canopy Temperature Characteristics of Chinese Cabbage Pakchoi ( L.)].

The aim of this study was to clarify the response characteristics of Chinese cabbage pakchoi ( L.) under two particle size (100 nm and 1000 nm) polystyrene microplastic (PS-MPs) stress conditions. This study can provide a theoretical basis and experimental reference for the interpretation of the physiological and ecological mechanism of microplastic pollution and the bioremediation of microplastic-contaminated soil.

[The effect of pro-angiogenic factors and their receptors on angiogenesis in hepatocellular carcinoma].

Objective: To explore the effect of pro-angiogenic factors and their receptors on angiogenesis in hepatocellular carcinoma.

Methods: Expression of VEGF/KDR and Angiopoietins/Tie2 was detected by RT-PCR and Western blot in 15 cases with hepatocellular carcinoma, 15 tumor adjacent tissues (<1 cm, >5 cm), 8 cirrhotic liver, and 4 normal liver. Immunohistochemistry (IHC) was used to detect CD34 expression, and the relationship between neovascular density and angiogenesis was analyzed.
